Patient Expectations of Pain Versus Experienced Expectations of Pain Following Shoulder Injection. J Perianesth Nurs 2024:S1089-9472(23)01033-X. [PMID: 38231147 DOI: 10.1016/j.jopan.2023.10.024] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/21/2023] [Revised: 10/27/2023] [Accepted: 10/31/2023] [Indexed: 01/18/2024]
Abstract
PURPOSE Corticosteroids, platelet-rich plasma, and hyaluronic acid injections to either the subacromial space (SAS) or the glenohumeral joint (GHJ) of the shoulder are commonly used for diagnostic and therapeutic purposes in outpatient settings. The first aim of this study was to determine whether the anticipated pain level differed significantly from the actual pain level experienced by patients who underwent shoulder injections. The second aim was to determine whether there was a significant difference in these pain levels between SAS and GHJ injections. The secondary goal was to investigate the correlation between patients' demographic data, anxiety characteristics, and pain scores. DESIGN Prospective clinical study. METHODS This study involved patients who completed a three-part questionnaire prior as well as following an injections to the GHJ\SAS. FINDINGS Sixty-three patients (28 males; 35 females), mean age of 54.28 years (standard deviation 13.95, range 25 to 84) met the inclusion criteria. There was a significant difference between the anticipated and the experienced pain (visual analog score 6.03 vs 3.17, P < .001). Experienced pain of the GHJ injections (n = 34) was rated as being greater than that of the SAS injections (n = 29) with borderline significance (visual analog scale 3.79 vs 2.36; P = .05). Forty-five patients (71.42%) reported a decrease in at least one pain category between anticipated and experienced pain compared to an increase reported by two patients (3.17%). CONCLUSIONS Injections to the GHJ and SAS were shown to be significantly less painful than anticipated by the patients. GHJ injections were perceived as more painful than SAS injections. Communicating this evidence-based reassuring information with patients prior to an injection may alleviate fear of the procedure, reduce the perception of pain, and ultimately improve compliance with the procedure.

The anterior superior iliac spine is a reliable novel landmark for preemptive periacetabular analgesia in hip arthroscopy. J Hip Preserv Surg 2023; 10:119-122. [PMID: 37900892 PMCID: PMC10604053 DOI: 10.1093/jhps/hnad011] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/30/2023] [Revised: 02/16/2023] [Accepted: 04/07/2023] [Indexed: 10/31/2023] Open
Abstract
Appropriate post-operative (post-op) pain control has been shown to reduce length of stay and facilitate day case surgery. Periacetabular injection of bupivacaine is effective in pain reduction after hip arthroscopy. This study aims to evaluate the anterior superior iliac spine (ASIS) as an anatomical landmark to facilitate needle insertion prior to fluoroscopy. The meeting point derived from a vertical line one fingerbreadth distal to the ASIS and a longitudinal line from the greater trochanter (GT) was used as a landmark in 30 consecutive hip arthroscopy patients for periacetabular analgesia. The distance between the tip of the needle and the acetabular roof was measured via fluoroscopy. Needle location was corrected if needed, followed by periacetabular bupivacaine injection (at anterior, lateral and posterior joint aspects). Post-op pain was measured using the Visual Analog Scale (VAS) 4-6 h post-op and at discharge. The ASIS and GT were identified and used for periacetabular analgesia landmarks in all cases. Results revealed that 93.3% of needle entries fell within 10 mm of the lateral acetabular rim and only one case had fallen distal to it. The post-op mean VAS score was 1.03 (range 0-6, standard error - 0.30, median = 0). At hospital discharge, 90% (27/30 of patients) reported VAS score ≤ 5. Twenty-six of the 30 patients were discharged on the same day as the operation (remaining four patients stayed due to accommodation/traveling issues). The ASIS and GT can be used as an anatomical landmark for periacetabular analgesia in hip arthroscopy with reproducible needle location, significant analgesic effect and minimal radiation.

The "Selfie Test": A Novel Test for the Diagnosis of Lateral Epicondylitis. MEDICINA (KAUNAS, LITHUANIA) 2023; 59:1159. [PMID: 37374364 DOI: 10.3390/medicina59061159] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/20/2023] [Revised: 06/12/2023] [Accepted: 06/14/2023] [Indexed: 06/29/2023]
Abstract
Background: Lateral epicondylitis (LE) is one of the most diagnosed elbow pathologies. The purpose of this study was to determine the diagnostic test accuracy of a new test (selfie test) for the diagnosis of LE. Methods: Medical data were collected from adult patients who presented with LE symptoms and ultrasound findings that supported the diagnosis. Patients underwent a physical examination, including provocative tests for diagnosis as well as the selfie test, and were asked to fill out the Patient-Rated Tennis Elbow Evaluation (PRTEE) questionnaire and subjectively rate the activity of their affected elbow. Results: Thirty patients were included in this study (seventeen females, 57%). The mean age was 50.1 years old (range of 35 to 68 years). The average duration of symptoms was 7 ± 3.1 months (range of 2 to 14 months). The mean PRTEE score was 61.5 ± 16.1 (range of 35 to 98), and the mean subjective elbow score was 63 ± 14.2 (range of 30 to 80). Mill's, Maudsley's, Cozen's, and the selfie tests had sensitivities of 0.867, 0.833, 0.967, and 0.933, respectively, with corresponding positive predictive values of 0.867, 0.833, 0.967, and 0.933. Conclusions: The selfie test's active nature, which allows patients to perform the assessment themselves, could be a valuable addition to the diagnostic process, potentially improving the accuracy of the diagnosis of LE (levels of evidence: IV).

Violation of expectations is correlated with satisfaction following hip arthroscopy. Knee Surg Sports Traumatol Arthrosc 2022; 31:2023-2029. [PMID: 36181523 DOI: 10.1007/s00167-022-07182-1] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/05/2022] [Accepted: 09/26/2022] [Indexed: 11/07/2022]
Abstract
PURPOSE The mechanism by which preoperative expectations may be associated with patient satisfaction and procedural outcomes following hip preservation surgery (HPS) is far from simple or linear. The purpose of this study is to better understand patient expectations regarding HPS and their relationship with patient-reported outcomes (PROs) and satisfaction using machine learning (ML) algorithms. METHODS Patients scheduled for hip arthroscopy completed the Hip Preservation Surgery Expectations Survey (HPSES) and the pre- and a minimum 2 year postoperative International Hip Outcome Tool (iHOT-33). Patient demographics, including age, gender, occupation, and body mass index (BMI), were also collected. At the latest follow-up, patients were evaluated for subjective satisfaction and postoperative complications. ML algorithms and standard statistics were used. RESULTS A total of 69 patients were included in this study (mean age 33.7 ± 13.1 years, 62.3% males). The mean follow-up period was 27 months. The mean HPSES score, patient satisfaction, preoperative, and postoperative iHOT-33 were 83.8 ± 16.5, 75.9 ± 26.9, 31.6 ± 15.8, and 73 ± 25.9, respectively. Fifty-nine patients (86%) reported that they would undergo the surgery again, with no significant difference with regards to expectations. A significant difference was found with regards to expectation violation (p < 0.001). Expectation violation scores were also found to be significantly correlated with satisfaction. CONCLUSION ML algorithms utilized in this study demonstrate that violation of expectations plays an important predictive role in postoperative outcomes and patient satisfaction and is associated with patients' willingness to undergo surgery again.

Preoperative Expectations Do Not Correlate With Postoperative iHOT-33 Scores and Patient Satisfaction Following Hip Arthroscopy for the Treatment of Femoroacetabular Impingement Syndrome. Arthroscopy 2022; 38:1869-1875. [PMID: 34838646 DOI: 10.1016/j.arthro.2021.11.027] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/20/2021] [Revised: 11/13/2021] [Accepted: 11/14/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE To examine the correlation between preoperative patient expectation and International Hip Outcome Tool (iHOT-33) score and postoperative satisfaction of patients undergoing hip arthroscopy for the treatment of femoroacetabular impingement syndrome. METHODS Patients scheduled for surgery completed the Hip Preservation Surgery Expectations Survey (HPSES), as well as the preoperative and a minimum 2-year postoperative iHOT-33. Patient demographics that were collected included gender, age, occupation, and body mass index (BMI). At the latest follow-up, patients were evaluated for their subjective satisfaction and postoperative complications. An in-depth analysis was performed to assess the correlation between HPSES, iHOT-33, and patient satisfaction. RESULTS Sixty-nine patients (62.3% males; mean age: 33.7 ± 13.1 years; BMI: 23.9 ± 3.5 kg/m2) were included in this study. The mean HPSES score was 83.8 ± 16.5. The mean iHOT-33 improved from 31.6 ± 15.8 preoperatively to 73 ± 25.9 postoperatively (95% CI = 35.2,47.8; P < .01), and the mean patient satisfaction was 75.9 ± 26.9. There were no statistically significant differences in mean HPSES score between males and females (95% CI = 79.9,87.8; P = .35) nor between different occupational groups (95% CI = 79.4,87.6, P = .095). No correlation was found between age and HPSES score (r = .036; P =.76). There was a negligible correlation between HPSES score and postoperative iHOT-33 score (r = -.117; P = .34) and patient satisfaction (r = -.042; P = .73). Postoperative iHOT-33 score had a significant high correlation with patient satisfaction (r = .8; P < .001). CONCLUSION Preoperative expectations do not correlate with postoperative iHOT-33 scores and patient satisfaction with surgery at 2 years after surgery. Gender and occupation did not differ significantly with regard to preoperative expectations, and there was no correlation between age and HPSES score. LEVEL OF EVIDENCE IV, retrospective case series.

Abstract
INTRODUCTION Literature addressing postoperative pain management after hip arthroscopy is relatively scarce. This study aimed to assess if there was added analgesic benefit associated with postoperative intra-articular bupivacaine blockade for patients who received preoperative peri-acetabular blockade for hip arthroscopy procedures. METHODS 52 patients were included in this comparative cohort study. Group 1 consisted of 20 patients who received preoperative peri-acetabular blockade and postoperative intra-articular blockade. The control group (Group 2), consisted of 32 patients who received only preoperative peri-acetabular blockade. Postoperative pain was recorded via visual analogue scale (VAS) pain scores, analgesic consumption, and pain diaries for 2 weeks postoperatively. RESULTS Postoperative VAS pain scores were significantly lower in the experimental group at the 30-minute recovery room assessment (VAS scores Group 1: 1.1; Group 2: 3.00, p = 0.034). Other than the 30-minute recovery room assessment, VAS pain scores, narcotic medication consumption, and non-narcotic analgesic consumption did not differ between the 2 groups at any time point in the study period. CONCLUSIONS This study did not demonstrate significant clinical benefit for patients who receive postoperative intra-articular blockade in addition to preoperative peri-acetabular blockade with bupivacaine 0.5%. We recommend the use of preoperative peri-acetabular bupivacaine blockade without intra-articular blockade postoperatively for pain control in the setting of hip arthroscopy surgery.

Magnetic Resonance Imaging Is Not Reliable in Classifying Anterior Inferior Iliac Spine Morphology Compared to 3-Dimensional Computerized Tomography. Arthroscopy 2022; 38:793-798. [PMID: 34246520 DOI: 10.1016/j.arthro.2021.06.007] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/05/2021] [Revised: 05/30/2021] [Accepted: 06/06/2021] [Indexed: 02/02/2023]
Abstract
PURPOSE The purpose of this study is to determine the reliability of standard magnetic resonance imaging (MRI) evaluation of AIIS morphology compared with three-dimensional (3D) computerized tomography (CT) (reference standard). METHODS Sixty hips in 30 patients met the inclusion criteria. The images were reviewed and classified by two fellowship-trained orthopedic surgeons. A second imaging viewing session was conducted in the same manner for validation of AIIS evaluation. The agreement and accuracy indices between the two raters were calculated for each imaging modality (inter-rater agreement) as well the agreement across the imaging modality for each rater (intermethod agreement). RESULTS The inter-rater agreement for the morphological evaluation of the AIIS for the first session according to 3D CT was .553 (P < .05) and by means of MRI was .0163 (P < .05). The inter-rater agreement for the second session by means of 3D CT was .449 (P < .05) and according to MRI was 0 (P < .05). The inter-method agreement for rater 1 for the first session was .04 (P < 0.05), while the agreement for rater 2 was .016 (P < .05). The intermethod agreement for rater 1 on the second session was .35 (P < 0.05), while that of rater 2 was .297(P < .05). The overall accuracy of MRI compared to 3D CT for rater 1 for the first session was .531, .490, and .959 for types I, II, III respectively and .551, .531, and .980 for the second session for types I, II, and III respectively. The overall accuracy of MRI compared to 3D CT for rater 2 for the first session was .551, .469, and .918 for types I, II, III respectively and .633, .592, and .918 for the second session for types I, II, and III, respectively. CONCLUSION MRI evaluations and subsequent classifications of AIIS morphology demonstrated a poor to slight correlation compared with that of the reference standard of 3D CT.

Abstract
BACKGROUND Patient-reported outcome measures (PROMs) are essential clinical instruments used for assessing patient function, assisting in clinical decision making, and quantifying outcomes of surgical and nonsurgical management. However, PROMs are often designed using patients with preexisting pathology and typically assume that a patient without the pathology would have a perfect or near perfect score. This may result in unrealistic expectations or falsely underestimate how well a patient is doing after treatment. The influence of age on PROMs about the hip of healthy individuals has not been studied. HYPOTHESIS We hypothesize that in asymptomatic individuals hip-specific PROM scores will decrease in an age-dependent manor. STUDY DESIGN Cross-sectional study; Level of evidence, 3. METHODS In this multicenter survey study, volunteers who denied preexisting hip pathology and previous hip surgery completed 3 PROMs online or as traditional paper questionnaires. The International Hip Outcome Tool (iHOT), the modified Harris Hip Score (mHHS), and the Hip Outcome Score-Activities of Daily Living (HOS-ADL) and HOS-Sport were completed. Analysis of variance with a Tukey post hoc test was used to analyze differences in PROMs among subgroups. An independent-samples Student t test and a χ2 test were used to analyze differences in continuous and categorical data, respectively. RESULTS In total 496, 571, 534, and 532 responses were collected for the iHOT, mHHS, HOS-ADL, and HOS-Sport, respectively. Respondents' PROMs were scored and arranged into 3 groups by age: <40 years, 40 to 60 years, and >60 years. The iHOT, mHHS, HOS-ADL, and HOS-Sport of these asymptomatic respondents all decreased in an age-dependent manner: iHOT (<40, 94.1; 40-60, 92.4; >60, 87.0), mHHS (<40, 94.8; 40-60, 91.3; >60, 89.1), HOS-ADL (<40, 98.4; 40-60, 95.0; >60, 90.9), and HOS-Sport (<40, 95.7; 40-60, 82.9; >60, 72.9) (analysis of variance between-group differences, P < .05). CONCLUSION This study demonstrated that the iHOT, mHHS, and HOS-ADL and HOS-Sport scores in asymptomatic people decrease in an age-dependent manner. It is important to compare a patient's outcome scores with the age-normalized scores to establish an accurate reference frame with which to interpret outcomes.

Accelerated rehabilitation following reverse total shoulder arthroplasty. J Shoulder Elbow Surg 2021; 30:e545-e557. [PMID: 33418090 DOI: 10.1016/j.jse.2020.11.017] [Citation(s) in RCA: 9] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/15/2020] [Revised: 11/12/2020] [Accepted: 11/16/2020] [Indexed: 02/01/2023]
Abstract
BACKGROUND Postoperative rehabilitation is considered essential and indeed routine practice following rTSA. However, the optimal approach to postoperative rehabilitation is unknown, based on protocols for anatomic TSA, and published literature is sparse, as is the quantity and quality of research evidence. The aim of this study is to outline the accelerated rehabilitation protocol (with immediate activity and no immobilization at all) following reverse total shoulder arthroplasty (rTSA) and assess its safety and effectiveness compared to the more conservative rehabilitation protocols of immobilization in a sling for 6 weeks and for 3 weeks. MATERIALS AND METHODS Between July 2005 and October 2017, a total of 357 consecutive rTSA in 320 patients underwent a primary rTSA and were included in the study. Patients were divided into 3 groups depending on rehabilitation protocol (6 and 3 weeks' postoperative immobilization, respectively, for groups 1 and 2, and no immobilization for group 3). Patients were assessed preoperatively and reviewed at 3 weeks, 3, 6, and 12 months, and yearly thereafter postoperatively. Constant score (CS), Subjective Shoulder Value (SSV), patient satisfaction, and pain scores were used at each appointment and patients assessed both clinically and radiographically. RESULTS Mean age at surgery was 76 years (range 40-93). At 1-year follow-up, the CS improved from 16.6 (adjusted 23.9) to 63.2 (adjusted 91.5) in group 1 (n = 114), from 21.5 (adjusted 30.7) to 67.7 (adjusted 98.4) in group 2 (n = 125), and from 22.6 (adjusted 31.3) to 66.6 (adjusted 94.9) in group 3 (n = 118). Pain score improved from 3.1/15 preoperatively to 12.5/15 postoperatively in group 1, from 3.5/15 to 13/15 in group 2, and from 3.7/15 to 12.5/15 in group 3. SSV improved to 8.5/10, 8.6/10, and 8.1/10 for groups 1, 2, and 3, respectively. Mean range of motion (ROM) improved to 142° elevation and 131° abduction in group 1, 153° elevation and 144° abduction in group 2, and 149° elevation and 146° abduction in group 3. No statistically significance differences were observed in CS, SSV, patient satisfaction, pain, and ROM between the 3 groups. Less postoperative complications were observed in group 3 (No immobilization). CONCLUSION Accelerated rehabilitation regime post rTSA without immobilization is safe and lead to reliable good clinical results and quick return to function. This study confirms noninferiority of the accelerated rehabilitation regime with fewer postoperative complications related to falls. Accelerated rehabilitation regime post rTSA have further psychological and emotional advantage to the patient, with earlier return to normal function and regaining independence. We recommend the accelerated rehabilitation regime without immobilization following rTSA.

Clinical Assessment and Treatment Options for Posterior Hip Pain. THE ISRAEL MEDICAL ASSOCIATION JOURNAL : IMAJ 2021; 23:534-540.

Abstract
Diagnosis and treatment of posterior hip pain has increased due to advancements in clinical, anatomical, biomechanical, and related pathological understandings of the hip. Due to its complexity and close anatomical relationship with many osseous, neurovascular, and musculotendinous structures, posterior hip pain must be appropriately categorized based on its origin. Therefore, it is crucial that clinicians are able to determine whether patient complaints are of extra-articular or intra-articular nature so that they can implement the optimal treatment plan. In the current review article, we discussed posterior hip pain with an emphasis on the main differential diagnoses of deep gluteal syndrome, ischiofemoral impingement, and hamstring tear/hamstring syndrome. For the appropriate diagnosis and etiology of posterior hip pain, a thorough and conclusive clinical history is imperative. Physicians should rule out the possibility of spinal involvement by physical examination and if necessary, by magnetic resonance imaging (MRI). Furthermore, because of the vicinity to other, non-orthopedic structures, an obstetric and gynecologic history, general surgery history, and urologic history should be obtained. Following the collection of patient history clinicians should adhere to an established and efficient order of evaluation starting with standing then to seated, supine, lateral, and prone testing. Imaging assessment of posterior hip pain begins with a standard anterior-posterior pelvic radiograph, in addition to frog-leg lateral. MRI is pivotal for assessing soft tissue-related extra-articular causes of hip in patients with posterior hip pain. Non-surgical treatment is preferred in most cases of deep gluteal syndrome, ischiofemoral impingement, pudendal nerve entrapment, and proximal hamstring pathologies. Surgical treatment is saved as a last resort option in cases of failed non-surgical treatment.

Abstract
To evaluate the outcome of a novel, combined endoscopic and mini-open repair (CEMR) of a chronic complete retracted proximal hamstring tendon avulsion (PHA). A retrospective case series of a single-surgeon database for all patients, with a minimum of 1-year follow-up, who underwent CEMR between July 2015 and September 2019 was performed. Patients were evaluated for their functional outcome using the Perth Hamstring Assessment Tool (PHAT). At the latest follow-up, patients were evaluated for their muscle strength, subjective satisfaction and post-operative complications. Twelve patients who underwent endoscopic surgery for chronic PHA were identified, of which seven patients underwent CEMR. After exclusion of one patient from the study due to an open claim for health insurance, six patients (five males) with a mean age of 48 years (range 20-61 years) were evaluated. The mean time from injury to surgery was 12 months (range 2-43 months). At a mean follow-up of 28 months (range 12-55 months), the average PHAT score was 73 (range 70-80). The mean subjective activity level percentage improved from 34 (range 20-50) pre-surgery to 81 (range 75-90) post-surgery. The mean strength of the quadriceps, hamstring at 30°, and hamstring at 90° of the operated leg compared to the uninjured leg did not differ significantly. One patient underwent adhesiolysis 1 year after the index procedure for treatment of subcutaneous adhesions. CEMR is a viable and safe option for the treatment of chronic complete proximal hamstring tears, with good to excellent short-term functional outcome. Level of evidence: IV.

Abstract
PURPOSE To compare ultrasound examination to false profile radiographs in identification and classification of AIIS morphology. The study hypothesis stated that sonographic imaging of the AIIS correlates well to AIIS morphology seen on false profile radiographs. METHODS Fifty-three hips in 30 consecutive patients met the inclusion criteria. A single, fellowship trained, orthopedic surgeon performed an ultrasound on all of the patients to evaluate the AIIS morphology. The patients underwent standing false profile radiographs. The US and radiographic images were independently reviewed and classified according to Hetsroni classification of AIIS morphology by two senior, fellowship trained, orthopedic surgeons. Agreement between the two raters was calculated for each imaging modality (inter-rater agreement) as well as the agreement between the rating in each modality by the same rater ("inter-method" agreement). RESULTS The agreement between the raters (inter-rater agreement) for morphologic evaluation of the AIIS by means of FP view was 88.8% (p < 0.001) and that by means of US was 81.5%(p < 0.001). The overall accuracy of the US compared to the FP view was 92.3% (48/52) for both rater 1 and 2. CONCLUSION This study showed near-perfect agreement in analyzing the morphology of the AIIS in a group of patients with hip pathology. Office sonographic evaluation of the AIIS is reliable and, therefore, may be routinely utilized in the clinic setting avoiding unnecessary radiation exposure to the patient.

Abstract
Background: With a greater understanding of the importance of the acetabular labrum in the function of the hip, labral repair is preferred over debridement. However, in some scenarios, preservation or repair of the labrum is not possible, and labral reconstruction procedures have been growing in popularity as an alternative to labral resection. Purpose: To provide an up-to-date analysis of the literature to determine the overall efficacy of labral reconstruction when compared with labral repair or resection. Study Design: Systematic review; Level of evidence, 3. Methods: PubMed, Embase, and MEDLINE databases were searched for literature regarding labral reconstruction in the hip before July 21, 2020. The results were screened and evaluated by 2 reviewers, and a third reviewer resolved any discrepancies. The final studies were evaluated using the MINORS (Methodological Index for Non-randomized Studies) score. Results: There were 7 comparative studies that fit the inclusion criteria, with 228 hips from 197 patients. The mean follow-up was 34.6 months, and the mean age of all patients was 38.34 years. There were slightly more female patients than male patients (105 vs 92). Arthroscopic reconstruction was performed in 86% of studies (6/7); open surgical techniques, in 14% (1/7). A variety of grafts was used in the reconstructions. The indications for labral reconstruction and outcome measures varied in these publications. Nine patients were lost follow-up, and 6 patients converted to total hip replacement postlabral reconstruction. The assessment of these comparative studies illustrated statistically equivalent results between labral reconstruction and labral repair. Comparisons of labral reconstruction with labral resection also showed statistically equivalent postoperative patient-reported outcome scores; however, the rates of conversion to total hip arthroplasty were significantly higher in the population undergoing resection. Conclusion: The review of current available comparative literature, which consists entirely of level 3 studies, suggests that labral reconstruction does improve postoperative outcomes but does not demonstrate superiority over repair. There may, however, be benefit to performing labral reconstruction over resection owing to the higher rate of conversion to total hip arthroplasty in the labral resection group.

Midterm Outcomes and Satisfaction After Hip Arthroscopy Are Associated With Postoperative Rehabilitation Factors. Orthop J Sports Med 2021; 9:2325967120981888. [PMID: 33614802 PMCID: PMC7869163 DOI: 10.1177/2325967120981888] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/25/2020] [Accepted: 11/03/2020] [Indexed: 11/16/2022] Open
Abstract
Background: Arthroscopic hip-preservation surgery is commonly performed to address
nonarthritic sources of hip pain in young, active individuals. However,
there is little evidence to support postoperative rehabilitation protocols,
including the most appropriate frequency and length of individual formal
physical therapy sessions. There is also a lack of information to look at
patients’ perceived value of their home program/self-practice in relation to
outcomes. Purpose: To investigate postoperative rehabilitation factors after hip arthroscopy
related to formal physical therapy and home program/self-practice and their
correlation with patient outcomes and satisfaction. Study Design: Cohort study; Level of evidence, 3. Methods: A total of 125 patients who underwent hip arthroscopy for femoroacetabular
impingement syndrome and a labral tear (75 men) were included. The mean age
was 34.6 ± 14.4 years, and the mean follow-up time was 4.9 ± 1.6 years. Hip
Outcome Score–Activities of Daily Living subscale (HOS-ADL) scores, overall
satisfaction scores, and factors related to supervised physical therapy and
home program/self-practice were collected. Correlations between continuous
variables and differences in the length of individual formal physical
therapy and patients’ rating of the importance of their home
program/self-practice between those who would and those who would not
undergo surgery again were assessed. Results: The frequency and length of individual formal physical therapy sessions were
significantly correlated with postoperative HOS-ADL scores
(r = 0.22, P = .014; and
r = 0.24, P = .007, respectively) and
level of satisfaction (r = 0.24, P = .007;
and r = 0.21, P = .02, respectively). The
length of individual formal physical therapy sessions was significantly
greater in those who noted they would undergo surgery again (35.3 vs 26.3;
P = .033). A significant correlation was identified
between the rating of the importance of their home program/self-practice and
postoperative HOS-ADL scores (r = 0.29; P
= .001) and their level of satisfaction (r = 0.23;
P = .009). There was a significant difference in the
rating of the importance of their home program/self-practice between those
who would undergo surgery again and those who would not (8.9 vs 7.8;
P = .007). Conclusion: Surgeons and physical therapists should emphasize the value of home
program/self-practice when it comes to outcomes and may want to encourage
their patients to participate in more frequent, longer, formal physical
therapy sessions.

Comparison of Caudal Block vs. Penile Block vs. Intravenous Fentanyl Only in Children Undergoing Penile Surgery: A Prospective, Randomized, Double Blind Study. Front Pediatr 2021; 9:654015. [PMID: 33842412 PMCID: PMC8033002 DOI: 10.3389/fped.2021.654015] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/15/2021] [Accepted: 03/03/2021] [Indexed: 11/16/2022] Open
Abstract
Objectives: Penile surgery is commonly performed in pediatric surgical centers. There is no consensus regarding which analgesic method is most effective in controlling pain in these children. Methods: Consecutive children between 4 months and 16 years of age who underwent elective penile surgery were recruited. After inhaled induction of anesthesia, children were randomized to one of three methods of intraoperative analgesia: caudal block, IV fentanyl titrated to surgical response and spontaneous respiration, or dorsal penile nerve block (DPNB). All patients were given inhaled agents; fentanyl was added if either block was insufficient. Demographic data, analgesic use and pain scores were recorded by a blinded investigator in the PACU and ward. Pain scores, analgesic requirement, and recovery parameters of returning to normal activity level, eating, and voiding post-operatively for up to 4 days, were compared. Results: 116 children were recruited. Pain scores in the post anesthesia care unit were significantly lower in the DPNB and caudal block groups compared to the fentanyl group for the first 30 postoperative min. Pain scores and analgesic use were subsequently similar among the three groups for the rest of the study period. There was no statistical difference in time to eat, return to normal activity or in parental satisfaction scores among the groups. There was a trend toward earliest time to void in the DPNB group. Conclusions: Regional blocks most effectively controlled pain for 30 min after surgery. The choice of intra-operative analgesia protocol had no effect on later pain and recovery parameters.

Abstract
PURPOSE This study was designed to (1) evaluate the clinical outcomes after arthroscopic subspinal decompression in patients with hip impingement symptoms and low AIIS, and to (2) assess the presence of low anterior inferior iliac spine on the pre-operative radiographs of patients with established subspinal impingement diagnosed intra-operatively. METHODS Retrospective analysis of patients who underwent arthroscopic subspinal decompression has been performed. The indications for surgery were femoroacetabular impingement (FAI), or subspinal impingement. Pre-operative radiographs were assessed for anterior inferior iliac spine type. Intra-operative diagnosis of low anterior inferior iliac spine was based on the level of anterior inferior iliac spine extension relative to the acetabulum and the presence of reciprocal labral and chondral lesions. In patients where low anterior inferior iliac spine was not diagnosed on pre-operative radiographs, the pre-operative radiographs were re-read retrospectively to assess missed signs of low anterior inferior iliac spine. RESULTS Thirty-four patients underwent arthroscopic subspinal decompression between 2012 and 2015. The patients were followed for a median of 25 months (13-37 months). Intra-operatively, grade 2 anterior inferior iliac spine was found in 27 patients and grade 3 anterior inferior iliac spine was found in 7 patients. MHHS, HOS, and HOSS scores increased from median (range) pre-operative scores of 55 (11-90), 48 (20-91) and 20 (0-80) to 95 (27-100), 94 (30-100) and 91 (5-100), respectively (p < 0.0001, p = 0.001, p < 0.0001, respectively). Pre-operative diagnosis of low AIIS was made in 6/34 patients via AP radiographs. On retrospective analysis of pre-operative radiographs, signs of low AIIS were still not observed in 21/34 (61.8%) patients. CONCLUSIONS Arthroscopic subspinal decompression of low AIIS yielded significantly improved outcome measures and high patient satisfaction at a minimum of 13 months follow-up. Low AIIS is often under-diagnosed on AP pelvis and lateral frog radiographs and if left untreated, may result in unresolved symptoms and failed procedure. LEVEL OF EVIDENCE IV.

Abstract
PURPOSE To determine if boney morphology influences the anatomic location of hip fractures in elderly patients. METHODS All patients with hip fractures between 2008 and 2012 who had hip radiographs taken prior to the fracture were reviewed. Fractures were classified as intracapsular or extracapsular and hip morphology was measured on the pre-fracture x-rays. Hip morphology was determined by alpha angle, lateral central edge angle, acetabular index, neck-shaft angle, hip axis length, femoral neck diameter, Tönnis classification for hip osteoarthritis (OA) and the presence of a crossover sign. RESULTS 148 subjects (78.4% female, age 83.5 years) with proximal femur fractures were included. 44 patients (29.7%) had intracapsular fractures and 104 (70.3%) had extracapsular fractures. 48% of patients had previous hip fractures on the contralateral side and 74.6% had the same type of fracture bilaterally. The rates of bilateral intracapsular and extracapsular fractures were similar (33.7% vs. 40.9% respectively, p = 0.39). Extracapsular fractures had a statically significant higher neck-shaft angle, a shorter hip axis length, a narrower femoral neck diameter and a higher grade of Tönnis classification of OA (p = 0.04, 0.046, 0.03, 0.02 respectively). Acetabular coverage and the proximal femoral head-neck junction, which were evaluated by lateral centre-edge angle (LCEA), acetabular index and the presence of a crossover sign, did not correlate with fracture type. The alpha angle > 40° had a statistically significant higher likelihood for extracapsular fractures (p = 0.013). CONCLUSIONS Acetabular coverage and proximal femoral head-neck junction morphology, were found to partially correlate with the location of hip fractures and do not fully elucidate fracture type susceptibility.

Abstract
BACKGROUND Hallux valgus is a common foot deformity that leads to functional disability with serious sequelae. Minimally invasive surgery is often used to treat hallux valgus in order to reduce wound complications and improve recovery time. The objective of this study was to compare a Simple, Effective, Rapid, Inexpensive (SERI) technique with a simple Chevron technique in patients with minimum of 1-year follow-up. METHODS AND MATERIALS Between the years 2014-2015, we performed a prospective study comparing the SERI minimally invasive technique to treat symptomatic hallux valgus with a standard chevron osteotomy technique. All procedures were performed by a single fellowship trained foot and ankle surgeon. Twenty-one patients were randomized to the SERI cohort and 15 to the standard Chevron technique. RESULTS The mean preoperative intermetatarsal angle (IMA) of the SERI group was 14.8 ± 1.9 (11.9-22.9). The mean preoperative IMA of the Chevron control group was 13.3 ± 2.3 (10.4-18.2) (p = 0.038). The mean IMA two weeks after the surgery was 6.0 ± 2.3 (2.4-12) in the SERI group, and 6.1 ± 3 (2.6-13.1) in the control group. At the two-week and 1-year follow-up, there was no significant difference found in the IMA between the two groups (p = 0.871). The mean hallux valgus angle reduction was 11.85 ± 4.88 (3-20.8) and 11.09 ± 6.51 (- 1.1 to 22.5) in the SERI and Chevron groups, respectively (p = 0.69). Neither groups reported symptomatic transfer metatarsalgia throughout the follow-up period. The SERI group had increased metatarsophalangeal joint (MTPJ) motion (p < 0.001); however, all other parameters with similar. CONCLUSION The SERI technique provided comparable outcomes at up to 1-year follow-up when compared with a standard Chevron osteotomy for moderate hallux valgus. This study demonstrated good reproducible results using the SERI technique for moderate hallux valgus. LEVEL OF EVIDENCE Level II Prospective Study. TRIAL REGISTRATION Approved by local IRB at MMC.

Postoperative Weightbearing Protocols After Arthroscopic Surgery for Femoroacetabular Impingement Does Not Affect Patient Outcome: A Comparative Study With Minimum 2-Year Follow-up. Arthroscopy 2020; 36:159-164. [PMID: 31864571 DOI: 10.1016/j.arthro.2019.08.012] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/11/2018] [Revised: 07/28/2019] [Accepted: 08/03/2019] [Indexed: 02/02/2023]
Abstract
PURPOSE To evaluate the effects of immediate postoperative weightbearing protocols after hip arthroscopy for femoroacetabular impingement (FAI) with minimum 2-year follow-up, as measured by patient-reported outcome measures and satisfaction rates. METHODS Between January 2011 and June 2016, patients undergoing hip arthroscopy for FAI and labral tears were reviewed. Exclusion criteria was previous hip pathology or arthroscopy, active Workers' Compensation claims, and concomitant pathologies impeding weightbearing. Patients who were operated on before September 2013 were treated with 3 weeks of postoperative non-weightbearing (NWB), with weightbearing as tolerated (WBAT) thereafter. From October 2013, patients were allowed immediate postoperative WBAT. RESULTS A total of 351 hip arthroscopic surgeries were performed; 133 of these patients met the inclusion criteria. Of the 133 included patients, 69 were in the NWB group and 64 were in the WBAT group. No differences were found in terms of sex (P = .603) or age (P = .241). No differences were found in postoperative scores (the Modified Harris Hip Score was 84.5 [range 79-89] for NWB vs 86.7 [78-89] for WBAT [P = .0.523], and the Hip Outcome Score was 83.1 [78-88] vs 88.4 [80-90], respectively; P = .130). Subjective rates of improvement, satisfaction score and the will to undergo surgery again did not differ between the groups (P = .674, P = .882, P = .730). The rate of subjects who met or exceeded the MCID in the NWB and WBAT groups was 82.6% and 81.2% for the Modified Harris Hip Score (P = .838) and 79.7% and 82.8% for the Hip Outcome Score (P = .647). There were no reported complications. Limitations include the possibility of the study being underpowered. CONCLUSIONS After a 2-year minimum follow-up, patient-reported outcome measures and satisfactory rates with immediate weightbearing after hip arthroscopy for isolated FAI syndrome and labral tears do not differ significantly from results after strict NWB rehabilitation protocols. Revising weightbearing restrictions may allow for a more comfortable rehabilitation process after arthroscopic hip surgery for FAI and labral repair. LEVEL OF EVIDENCE Level 3 - case-control study.

Abstract
Proximal hamstring avulsion is an uncommon injury which usually requires surgical intervention. When possible, primary surgical fixation is recommended. In chronic hamstring avulsion with significant retraction of the tendon, hamstring reconstructions using an autograft or allograft are required in order to bridge the gap. This is mainly performed using an open surgical technique. We describe a combined endoscopic and open surgical approach to hamstring reconstruction surgery.

Does capsular closure influence patient-reported outcomes in hip arthroscopy for femoroacetabular impingement and labral tear? J Hip Preserv Surg 2019; 6:199-206. [PMID: 31798927 PMCID: PMC6874774 DOI: 10.1093/jhps/hnz025] [Citation(s) in RCA: 15] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/03/2018] [Revised: 05/05/2019] [Accepted: 05/21/2019] [Indexed: 12/18/2022] Open
Abstract
Capsulotomy is necessary to facilitate instrument manoeuvrability within the joint capsule in many arthroscopic hip surgical procedures. In cases where a clear indication for capsular closure does not exist, surgeon's preference and experience often determines capsular management. The purpose of this study was to assess the influence of capsular closure on clinical outcome scores and satisfaction in patients who underwent hip arthroscopy surgery for femoroacetabular impingement (FAI) and labral tear. Data were prospectively collected and retrospectively analysed for hip arthroscopy surgeries with a minimum 2 years follow-up. Patients with developmental dysplasia of the hip, previous back or hip surgeries, and degenerative changes to this hip and secondary gains were excluded. Demographic data, intraoperative findings and patient-reported outcome scores were recorded, including the Modified Harris Hip Score (MHHS) and Hip Outcome Score (HOS). A total of 29 and 35 patients were included in the non-closure and closure groups, respectively. The mean follow-up time was over 3 years for both groups. The mean pre-operative and post-operative HOS scores and MHHS scores did not significantly differ between groups (pre-operative HOS: 65.6 and 66.3, P = 0.898; post-operative HOS: 85.4 and 87.2, P = 0.718; pre-operative MHHS: 63.2 and 58.4, P = 0.223; post-operative MHHS: 85.7 and 88.7, P = 0.510). Overall patient satisfaction did not differ significantly between groups (non-closure 86.3%, closure group 88.6%; P = 0.672). Capsular closure did not significantly influence satisfaction or clinical outcome scores in patients who underwent arthroscopic hip surgery for FAI or labral tear.

Abstract
The diagnosis and treatment of chondral lesions in the hip is an ongoing challenge in orthopedics. Chondral lesions are common and several classification systems exist to classify them based on severity, location, radiographic parameters, and potential treatment options. When working up a patient with a potential hip chondral lesion, a complete history, thorough physical exam, and ancillary imaging are necessary. The physical exam is performed with the patient in standing, supine, prone, and lateral positions. Plain film radiographs are indicated as the first line of imaging; however, magnetic resonance arthrogram is currently the gold standard modality for the diagnosis of chondral lesions outside of diagnostic arthroscopy. Multiple treatment modalities to address chondral lesions in the hip exist and new treatment modalities continue to be developed. Currently, chondroplasty, microfracture, cartilage transplants (osteochondral autograft transfer, mosaicplasty, Osteochondral allograft transplantation) and incorporation of orthobiologics (Autologous chondrocyte implantation, Autologous matrix-induced chondrogenesis, Mononuclear concentrate in platelet-rich plasma) are some techniques that have been successfully applied to address chondral pathology in the hip. Further refinement of these modalities and research in novel techniques continues to advance a surgeon’s ability to address chondral lesions in the hip joint.

Abstract
OBJECTIVE Drilling through bone is a complex action that requires precise motor skills of an orthopedic surgeon. In order to minimize plunging and soft tissue damage, the surgeon must halt drill progression precisely following penetration of the far cortex. The purpose of this study was to create a low-cost and easy-to-use drilling simulator to train orthopedic residents in reducing the drill plunging depth. DESIGN, SETTING, PARTICIPANTS This prospective observational study was performed in the division of orthopedic surgery of a single tertiary medical center. The participants included 13 residents and 7 orthopedic specialists. The simulator consisted of a synthetic femur bone model and ordinary modeling clay, and the training unit consisted of a disposable plastic tube (∼US$14), clamps (∼US$58), and a power drill + drill bit (standard hospital equipment). Plunging depths were measured by the simulator and compared between orthopedic specialists, the 6 "senior residents" (3+ years) and the 7 "junior residents" during a training session. Measurements were taken again 2 weeks following the training session. RESULTS Initially, the plunging depths of the junior residents were significantly greater compared to those of the orthopedic specialists (7.00 mm vs. 5.28 mm, respectively, p < 0.038). There was no similarly significant difference between the senior residents and the orthopedic experts ([6.33 mm vs. 5.28 mm, respectively; p = 0.18). The senior residents achieved plunging depths of 5.17 mm at the end of the training session and 4.7 mm 2 weeks later compared to 7.14 mm at the end of the training session and 6 mm 2 weeks later for the junior residents. CONCLUSIONS This study demonstrated the capability of a low-cost drilling simulator as a training model for reducing the plunging depth during the drilling of bone and soft tissue among junior and senior residents.

Abstract
This report presents a case of a 37-year-old female with a history of hip pain. Magnetic resonance arthrography revealed loose bodies within the joint and synovial hypertrophy indicative of synovial chondromatosis (SC). Hip arthroscopy revealed free chondral bodies and focal villonodular synovial proliferation. The focal synovial proliferation was excised, a total synovectomy performed, and all cartilaginous free bodies removed. A post-operative histological examination of the removed nodular mass and synovium yielded evidence of both SC and pigmented villonodular synovitis (PVNS). A 1-year post-operative clinical examination showed marked clinical improvement and no signs of recurrence on MR images. Despite the clinical similarities, PVNS and SC are two distinct conditions that, to our knowledge, have never been reported as simultaneously occurring in a hip joint. The simultaneous presence of both pathologies may suggest a common origin of synovial metaplasia.

Abstract
The acetabular labrum plays a key role in maintaining hip function and minimizing hip degeneration. Once thought to be a rare pathology, advances in imaging have led to an increase in the number of diagnosed labral tears. While still a relatively new field, labral reconstruction surgery is an option for tears that are irreparable or require revision after primary repair. Various autograft and allograft options exist when considering labral reconstruction. The first labral reconstruction surgery was described using the ligamentum teres capitis, and has since evolved, incorporating more graft sources and reconstructive techniques. The purpose of this review is to assess and describe the different graft sources and technique currently implemented by hip surgeons. Moreover, this review attempts to determine whether a single labral reconstructive graft type is superior to the others. Techniques using the Ligamentum teres capitis autograft, ITB autograft, gracilis autograft, quadriceps tendon autograft, capsular autograft, semitendinosus allograft, indirect head of the rectus femoris autograft, peroneus brevis tendon allograft and Tensor fascia lata allograft were found. Scoring was available on 5 out of the 9 graft types. The advantages and disadvantages of each graft source is described as a comparative tool. No single graft type has shown increased benefit in acetabular labral reconstruction. The lack of uniform outcome measurements hinders comparison of reported outcomes. Surgeons should make an informed decision based on their experience as well as the patient's history and needs when choosing which graft type would be best suited for their patients.

Abstract
PURPOSE This study was designed to compare the results of clavicle fracture open reduction internal fixation (ORIF) with standard horizontal incision versus vertical incision. METHODS ORIF surgery performed between October 2012 and August 2016 was included. The surgical approach was chosen according to surgeon preference as vertical or horizontal. Functional outcomes, fracture union, complications, scar appearance, skin irritation, and denervation around the scar were assessed at a minimum follow-up of three months. RESULTS Thirty-eight patients, age 39 ± 12 years, were operated upon, 22 through vertical incisions and 16 through horizontal incisions. There were no significant group differences in functional scores, fracture union, or complications. Two patients in the vertical incision group had a post-operative haematoma. The scar length was significantly shorter when a vertical incision was used (6.75 ± 1.25 cm vs 8.9 ± 2.3 cm, P = 0.001). The typical distribution of hypoesthetic skin area distal and lateral to the scar represented iatrogenic damage to the supraclavicular nerves and was found in 66% of patients. The mean hypoesthetic surface area was smaller in the vertical incision group (38 ± 29 cm2 vs 48 ± 28 cm2, P = non-significant). CONCLUSION Vertical incision results in shorter scars but may be associated with increased incidence of haematomas. Meticulous closure of the subcutaneous tissue is recommended.

Hip arthroscopy as a treatment for obturator neuropathy secondary to intra-pelvic ganglion: a case report. J Hip Preserv Surg 2018; 5:319-322. [PMID: 30393561 PMCID: PMC6206690 DOI: 10.1093/jhps/hny023] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/27/2018] [Accepted: 07/02/2018] [Indexed: 11/13/2022] Open
Abstract
The most common types of cystic lesions around the hip joint are synovial or ganglion cysts. In rare cases, the cysts can compress adjacent structures and cause symptoms to arise. Obturator neuropathy secondary to a hip ganglion cyst is a rare phenomenon, with scarce reports on suggested treatment options. Hip arthroscopy is a potential minimally invasive treatment that has yet to be described in such cases. We present a 52-year-old male suffering from obturator neuropathy caused by an intra-pelvic ganglion cyst arising from the hip joint. Hip arthroscopy was performed for decompression of the cyst and dilation of the stalk opening. Six-month post-operative follow-up showed resolution of symptoms and complete elimination of the cyst on magnetic resonance imaging.

Abstract
Background Acetabular cartilage lesions are a common abnormality found in patients undergoing hip arthroscopic surgery and may cause pain and functional limitations. Several strategies have been developed to treat chondral defects, with no overwhelming success. Recently, BST-CarGel has gained interest as a scaffolding material that can be injected into the microfracture site to stabilize the clot and facilitate cartilage repair. Purpose To perform a retrospective analysis of prospectively collected data to evaluate the safety profile and short-term clinical and radiographic outcomes of patients treated arthroscopically with BST-CarGel for acetabular chondral defects in conjunction with microfracture. Study Design Case series; Level of evidence, 4. Methods A retrospective chart review was performed on all patients who underwent hip arthroscopic surgery by the senior surgeon to identify those who had BST-CarGel applied to their hip from November 2014 to July 2016, and basic demographic information for those patients was obtained. Operative reports and patient charts were reviewed to assess intraoperative and postoperative complications as well as to obtain the details of surgery, including lesion size and treatment method of the labrum (repair vs reconstruction). All patients filled out self-reported questionnaires, including the international Hip Outcome Tool (iHOT), Hip Outcome Score-Activities of Daily Living (HOS-ADL), and Hip Outcome Score-Sports Profile (HOS-SP) at the time of consultation and at 1 year postoperatively, and results were used to assess the clinical outcomes of surgery. Results Thirty-seven patients (37 hips) with a mean age of 36.19 years at the time of the index procedure were evaluated. There were 30 male patients, and 20 procedures were performed on the right hip. The minimum follow-up was 1 year, with a mean follow-up of 12.72 months. There were no major adverse events of deep vein thrombosis, blood vessel or nerve damage, hemarthrosis, arthralgia, or device-related adverse events. Two patients (5.4%) were readmitted because of pain, probably resulting from an inflammatory reaction to BST-CarGel. At 1 year postoperatively, there were statistically significant improvements in the iHOT (40.4 to 59.1; P < .001), HOS-ADL (60.6 to 71.4; P = .02), and HOS-SP (36.9 to 51.6; P = .01) scores. When the patients were subdivided based on the chondral defect size, the iHOT score improved for all chondral defect sizes, and the HOS-SP score improved in patients with medium (2-4 cm2) and very large (>6 cm2) chondral defects. In addition, the iHOT score improved whether the patients had their labrum repaired or reconstructed (P < .001 and P = .02, respectively). Conclusion The arthroscopic treatment of chondral acetabular defects with BST-CarGel demonstrates a satisfactory safety profile, with statistically significant improvement in patient-reported clinical outcome scores, even for those with very large chondral defect sizes.

Acetabular labral reconstruction using the indirect head of the rectus femoris tendon significantly improves patient reported outcomes. Knee Surg Sports Traumatol Arthrosc 2018; 26:2512-2518. [PMID: 28717888 DOI: 10.1007/s00167-017-4641-4] [Citation(s) in RCA: 29] [Impact Index Per Article: 4.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/06/2017] [Accepted: 07/07/2017] [Indexed: 01/03/2023]
Abstract
PURPOSE AND HYPOTHESIS The aim of this study was to evaluate outcomes after acetabular labral reconstruction using the indirect head of the rectus femoris tendon. The study hypothesis stated that arthroscopic acetabular labral reconstruction may improve patient reported outcomes in patients with labral tears that were not amenable to repair. METHODS Between 2009 and 2015, the senior author performed 31 acetabular labral reconstructions using the indirect head of the rectus femoris tendon. The graft is harvested through the same arthroscopic portals established for the procedure. The graft was gradually secured to the acetabular rim starting at its origin to the myotendinous junction, reestablishing the suction seal of the joint. Medical records and surgical reports were reviewed for demographic data, and outcome measures were assessed with pre- and postoperative modified Harris Hip Scores (mHHS). RESULTS Twenty-two patients with follow-up of more than 2 years were evaluated. Fourteen procedures were revision hip arthroscopy and 8 were primary labral reconstruction in 13 males and 9 females. The median age was 43 (range 22-68 years old). The median follow-up time was 36.2 months with a range from 24 to 72 months. The median preoperative mHHS was 67.1. Postoperatively, patients improved to a median mHHS of 97.8 (range 73.7-100) (p < 0.0001). CONCLUSION Acetabular labral reconstruction using the indirect head of the rectus femoris tendon is a minimally invasive surgical procedure. The technique was applicable in all patients in this study with good outcomes. This procedure is clinically relevant for patients with large labral tears not amendable to labral repair as it offers good results using a local allograft. The local allograft is clinically advantageous as there is no additional donor-site morbidity and no risk of disease transmission. LEVEL OF EVIDENCE IV.

Abstract
Background: The results of arthroscopic anterior labral repair have demonstrated high
failure rates in patients with significant glenoid bone loss. Several
reconstruction procedures using a bone graft have been developed to overcome
bone loss. Purpose: The primary objective of this study was to generate a safety profile for
arthroscopic anatomic glenoid reconstruction using a distal tibial
allograft. The secondary objective was to evaluate the radiological outcomes
of patients who underwent this procedure. Study Design: Case series; Level of evidence, 4. Methods: This retrospective review included the medical charts and diagnostic images
of 42 consecutive patients who underwent arthroscopic shoulder stabilization
by means of capsule-labral reattachment and bony augmentation with a distal
tibial allograft. The safety profile was measured by detecting
intraoperative or postoperative complications, including neurovascular
(nerves and blood vessels) injuries, bleeding, infections, and dislocations.
A radiological evaluation was conducted by assessing computed tomography
(CT) scans obtained preoperatively and at approximately 6 months
postoperatively. Results: A total of 42 patients (29 male, 13 female) with a mean age of 26.73 ± 9.01
years were included. An excellent safety profile was observed, with no
intraoperative complications, neurovascular injuries, adverse events,
bleeding, or infections. CT bone scans were obtained for 31 patients, and
the mean follow-up for CT scanning (to measure resorption and union) was
6.31 ± 1.20 months (range, 6-7.5 months). There were no cases of nonunion or
partial union. Thirteen patients (42%) had no resorption, whereas 13 (42%)
and 5 (16%) patents had <50% and ≥50% resorption, respectively. Conclusion: Arthroscopic shoulder stabilization with distal tibial allograft
reconstruction is a safe operative procedure with a minimal risk to
neurovascular structures. Most patients had a healed allograft, but 16% of
patients had ≥50% resorption on CT at 6 months. Studies with a longer
follow-up are recommended for better assessment of the safety profile.

Abstract
BACKGROUND Previous research has revealed decreased bone mineral density (BMD) among children and adolescents who receive methylphenidate (MP) treatment for attention deficit hyperactivity disorder (ADHD). These findings have major clinical implications given that the prevalence of medication-treated ADHD is on the rise worldwide. We decided to investigate the clinical effect of MP exposure on the incidence of stress fractures, for which a low BMD is a risk factor. HYPOTHESIS Exposure to MP is a risk factor for stress fractures. STUDY DESIGN Case-control study; Level of evidence, 3. METHODS This is a case-control study of combat soldiers who served in the military for 3 years between 2005 and 2015. The case group included 2400 soldiers with at least 1 stress fracture diagnosed by a bone scan. The control group comprised 6187 combat soldiers without a diagnosis of a stress fracture. The use of MP was determined by an automated text search of medical records and manual sorting of the results. Other study variables included age; sex; weight; height; body mass index (BMI); place of birth; and characterization of fractures by location, side, and grade. Odds ratios of stress fractures, the attributable proportion among the exposed, and the population attributable fraction were calculated using standard contingency tables. Logistic regression was fitted after adjusting for covariates. RESULTS The previous use of MP was associated with a higher risk of stress fractures (odds ratio, 1.15 [95% CI, 1.07-1.24]). The attributable proportion was 13.2%, and the population attributable fraction was 0.3%. Logistic regression demonstrated an increased risk of stress fractures associated with past MP use, preserved after adjusting for BMI, sex, and place of birth ( P = .005). Female sex, BMI ≤20 kg/m2, and 20 < BMI ≤25 kg/m2 were independent positive predictors of a stress fracture, while African origin was a negative predictor. Most participants who used MP had only 1 fracture (77.8%), while the majority of participants who did not use MP in the past had ≥2 coincident fractures (53.5%) ( P = .003). CONCLUSION This study supports the hypothesis that an MP-associated reduction in BMD has a clinical effect in the form of an increased incidence of stress fractures. The high percentage of fractures attributed to MP use may serve as a basis for risk stratification, that is, the referral of patients with a history of MP use to BMD measurements.

Abstract
Prolonged sitting and mobilizing from a seated position are known to exacerbate the symptoms in patients with hip pathology. For patients who lack mobility and require extended periods of time in seated positions, such as amputees, the symptoms of femeroacetabular impingement can be debilitating and limit their ability to operate a wheelchair, use a prosthetic limb or complete activities of daily living. Hip arthroscopy surgery offers a minimally invasive technique to treat hip pathology but requires hip distraction to facilitate instrument maneuverability. Invasive methods of hip distraction have been previously described for use in amputees for hip arthroscopy. We herein describe a non-invasive surgical technique for hip distraction in the below-knee amputation patient.

Abstract
The objectives of this study are to survey the weight-bearing limitation practices and delay for returning to running and impact sports of high volume hip arthroscopy orthopedic surgeons. The study was designed in the form of expert survey questionnaire. Evidence-based data are scares regarding hip arthroscopy post-operative weight-bearing protocols. An international cross-sectional anonymous Internet survey of 26 high-volume hip arthroscopy specialized surgeons was conducted to report their weight-bearing limitations and rehabilitation protocols after various arthroscopic hip procedures. The International Society of Hip Arthroscopy invited this study. The results were examined in the context of supporting literature to inform the studies suggestions. Four surgeons always allow immediate weight bearing and five never offer immediate weight bearing. Seventeen surgeons provide weight bearing depending on the procedures performed: 17 surgeons allowed immediate weight bearing after labral resection, 10 after labral repair and 8 after labral reconstruction. Sixteen surgeons allow immediate weight bearing after psoas tenotomy. Twenty-one respondents restrict weight bearing after microfracture procedures for 3–8 weeks post-operatively. Return to running and impact sports were shorter for labral procedures and bony procedures and longer for cartilaginous and capsular procedures. Marked variability exists in the post-operative weight-bearing practices of hip arthroscopy surgeons. This study suggests that most surgeons allow immediate weight bearing as tolerated after labral resection, acetabular osteoplasty, chondroplasty and psoas tenotomy. For cartilage defect procedures, 6 weeks or more non-weight bearing is suggested depending on the area of the defect and lateral central edge angle. Delayed return to sports activities is suggested after microfracture procedures. The level of evidence was Level V expert opinions.

Abstract
The purpose of this study is to demonstrate the assessment of intra-capsular femoral head and neck tumors, and to describe the arthroscopic surgical technique used to resect and fill the bone defects. Three cases of benign femoral head and neck lesions are presented. Two benign enchondromas and one benign osteochondroma were resected arthroscopically. Traction was used in one case. Modified Harris Hip Score improved in all three cases to scores of 95 or greater with an average improvement of 16 points with a minimum follow up of 15 months. Arthroscopic surgical resection of intra-capsular femoral hip lesions offers an effective alternative to open resection. This technique offered good outcomes in the limited cohort. We suggest that arthroscopic resection of intra-capsular femoral hip lesions be considered in relevant cases as an alternative to open resection.

Abstract
The aim of this study was to analyze dynamic patterns for scanning femoroacetabular impingement (FAI) radiographs in orthopedics, in order to better understand the nature of expertise in radiography. Seven orthopedics residents with at least two years of expertise and seven board-certified orthopedists participated in the study. The participants were asked to diagnose 15 anteroposterior (AP) pelvis radiographs of 15 surgical patients, diagnosed with FAI syndrome. Eye tracking data were recorded using the SMI desk-mounted tracker and were analyzed using advanced measures and methodologies, mainly recurrence quantification analysis. The expert orthopedists presented a less predictable pattern of scanning the radiographs although there was no difference between experts and non-experts in the deterministic nature of their scan path. In addition, the experts presented a higher percentage of correct areas of focus and more quickly made their first comparison between symmetric regions of the pelvis. We contribute to the understanding of experts’ process of diagnosis by showing that experts are qualitatively different from residents in their scanning patterns. The dynamic pattern of scanning that characterizes the experts was found to have a more complex and less predictable signature, meaning that experts’ scanning is simultaneously both structured (i.e. deterministic) and unpredictable.

Surgical Technique: Arthroscopic Osteoplasty of Anterior Inferior Iliac Spine for Femoroacetabular Impingement. Arthrosc Tech 2016; 5:e601-6.

Abstract
The anterior inferior iliac spine (AIIS) has variable morphology that correlates with hip range of motion. Subspinal impingement is an extracapsular cause for femoroacetabular impingement (FAI) and is clinically significant because it results in decreased range of motion and groin pain with flexion-based activity. In symptomatic patients with AIIS extension to or below the acetabular rim, AIIS decompression is considered part of an FAI corrective procedure. A consistent exposed bony area on the anterior and inferomedial aspect of the AIIS serves as a "safe zone" of resection allowing for decompression with preservation of the origin of the rectus femoris tendon. This surgical note describes a technique for AIIS decompression. The goal for low AIIS osteoplasty is to resect the AIIS to 2 burr widths (using a 5.5-mm burr) above the acetabular rim, achieving an 11-mm clearance, creating a type I AIIS. The resultant flat anterior acetabular surface between the most anteroinferior prominent point of the AIIS and the acetabular rim allows for free movement of the hip joint without impingement. Careful execution of AIIS decompression can alleviate clinical symptoms of FAI and restore function to the hip joint.

Arthroscopic Labrum Reconstruction in the Hip Using the Indirect Head of Rectus Femoris as a Local Graft: Surgical Technique. Arthrosc Tech 2016; 5:e361-4.

Abstract
The importance of the acetabular labrum has been well documented for the health and function of the hip joint. Labral reconstruction has proven effective but often requires the use of a cadaveric allograft or auto graft from the fascia lata or gracilis. The indirect head of the rectus femoris is in close proximity with the anterior superior acetabulum, which is the most common site of labral tears. Using the indirect head of the rectus femoris as a local graft minimizes surgical invasiveness by mitigating the need to harvest the graft from a different location, in case of an autograft, and by minimizing donor site morbidity and damage to local tissues. The graft is harvested and fixed to the acetabular rim through the same arthroscopic portals. Hip labral reconstruction using the reflected head of the rectus femoris tendon is a minimally invasive surgical procedure that restores stability to the hip joint, is applicable in all patients undergoing hip labral reconstruction, and offers decreased tissue morbidity compared with other grafting techniques.

Abstract
PURPOSE To compare outcomes of 3 patient groups undergoing hip arthroscopy. METHODS This study included 138 consecutive hip arthroscopies (106 analyzed) for femoral-acetabular impingement (FAI) with or without labral tear in patients with a minimum 1-year follow-up. Inclusion criteria included patients older than 18 with clinical or radiologic manifestation of FAI with or without labral tear. Exclusion criteria included previous hip surgery and various hip pathologies. Patients were classified into 3 study groups. Group 1 included work-related injuries with active claims ACs (n = 33); mean age, 32 (range, 19 to 63); group 2 included sports injuries with no ACs (n = 35); mean age, 32 (range, 18 to 69); and group 3 included non-sports-related injuries without pending ACs (NAS; n = 38); mean age, 45 (range, 20 to 68). Outcomes were assessed using modified Harris hip scores (mHHS) and hip outcome scores (HOS) preoperatively and during the final evaluation. RESULTS Baseline score for all groups did not significantly differ (P = .210 for mHHS, P = .176 for HOS). All groups significantly improved from preoperative to final evaluation (group 1: mHHS P = .42, HOS P = .001; group 2: mHHS P < .001, HOS P < .001; group 3 NAS: mHHS P = .001, HOS P = .007). AC patients had the lowest final evaluation scores, while the sports group had the highest. The NAS group did not differ from either group at final evaluation. Preoperative and final evaluation scores inversely correlated with age (r range, -24 to -28; P < .05). CONCLUSIONS This study has shown that patients may benefit from arthroscopic repair of FAI and labral tears regardless of ACs. The level of improvement, however, is not constant across patients with different characteristics. Moreover, it appears that age may impact perceived improvement after hip arthroscopy. Hip arthroscopy as an intervention in patients with ACs provided positive outcomes, corroborating that an AC is not a contraindication for this procedure. LEVEL OF EVIDENCE Level III, retrospective comparative study.

Abstract
BACKGROUND Heterotopic ossification (HO) after hip arthroscopic surgery is a common complication and may be associated with clinical sequelae such as pain, impingement, and decreased range of motion. Nonsteroidal anti-inflammatory drugs (NSAIDs) are commonly used medications for reducing or preventing HO. HYPOTHESIS/PURPOSE The purpose of this study was to evaluate the effectiveness of short-term selective cyclooxygenase-2 (COX-2) inhibitors used for HO prophylaxis after hip arthroscopic surgery. The hypothesis was that postoperative HO prophylaxis with 600 mg etodolac once daily for 2 weeks would significantly reduce the incidence of HO after hip arthroscopic surgery when compared with no prophylaxis. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Between July 2010 and April 2014, a total of 263 consecutive patients underwent hip arthroscopic surgery, performed by a single surgeon, for various pathological abnormalities at 1 medical center. The initial 163 patients received no postoperative NSAID prophylaxis for HO, and the subsequent 100 patients received 600 mg etodolac once daily for 2 weeks postoperatively. Prophylaxis compliance data, gastrointestinal side effects, and postoperative radiographs for HO were monitored. RESULTS A total of 100 control patients and 63 study patients met the inclusion criteria. The mean follow-up period was 12.88 months. No significant differences were observed in terms of age, sex, follow-up, or procedures performed. No gastrointestinal bleeding was observed. Radiographic findings of HO were present in 36 of 100 control patients with 17, 15, and 4 classified as having Brooker grades 1, 2, and 3, respectively. No patients in the study group presented with HO, and a significant difference in the HO rate between groups was observed (P < .0001). CONCLUSION HO after hip arthroscopic surgery is a relatively common complication, with a rate of 19% for Brooker grade ≥2 in the patients who did not receive NSAID prophylaxis. No HO was found in the patients who received short-term COX-2 inhibitor prophylaxis. The short-term administration of 600 mg etodolac once daily for 2 weeks was found to be safe and effective in preventing HO in patients undergoing hip arthroscopic surgery. HO prophylaxis protocols based on short-term etodolac treatment may be considered after hip arthroscopic surgery.

Abstract
INTRODUCTION Intracapsular hip fractures (ICHF) are a common cause of morbidity and mortality and pose a great economic burden on the health care systems. Appropriate surgical treatment requires balancing optimal outcomes with the cost of treatment to the health care system. While in elderly patients with displaced ICHF arthroplasty became the standard of care, the internal fixation method for conserving the femoral head in younger patients or in nondisplaced ICHF is still in debate. We compared a dynamic locking plate with the standard cancellous cannulated screws (CCS) for treatment of nondisplaced ICHF. METHODS All patients treated with internal fixation for nondisplaced ICHF between July 2009 and December 2012 at our level one trauma center were included in this study. Patients treated with Targon FN (Aesculap) implants and CCS (Synthes) were compared. Charts were reviewed for demographics, intraoperative data and peri/post operative complications retrospectively. Radiographical analysis, pain (VAS), quality of life (SF12) and function (MHHS) data were prospectively gathered. RESULTS One hundred and fifteen non-displaced ICHFs were treated with internal fixation, 81 with CCS and 34 with Targon FN implant; the mean follow-up was 19 and 28 months, respectively. Group fracture characteristics (Garden/Powel classification), and demographics, excluding age, were not significantly different. Post-operative revision rates of the Targon FN and CCS groups, perioperative complications were not statistically different (p>0.05). Quality of life (SF-12), function (Modified Harris Hip Score) and Visual Analogue Scale (VAS) pain scores were not statistical different. CONCLUSIONS Complication rates and clinical outcomes for the treatment of nondisplaced ICHF with Targon FN and SCC showed no significant differences. Based on this evidence in consideration of the substantial cost differential between the Targon FN and SCC we suggest SCC for treatment of nondisplaced ICHF. LEVEL OF EVIDENCE III.

Abstract
BACKGROUND The popularity of bicycle riding for recreation, exercise and transportation has grown enormously in recent years, which has led to an increased incidence of bicycle-related injuries. While these injuries involve mainly the musculoskeletal system, data on shoulder-specific injuries incurred while bike riding are lacking. Classifying these shoulder injuries may provide insight and assistance in the creation and implementation of effective protective gear and measures. OBJECTIVES To investigate the types and mechanisms of shoulder injuries among cyclists. METHODS This study retrospectively examined all cyclists who incurred shoulder injuries while riding and were admitted to the emergency department and shoulder clinic between January 2008 and November 2013. The study included 157 subjects with various bicycle-related shoulder injuries treated with either conservative or surgical measures. RESULTS Eighty-four percent of injuries were caused by a direct blow to the shoulder, 7% by falling on an outstretched hand, 6% were traction injuries, and 3% were due to hyperabduction. Nine different clinical types of injury were observed; the most common injuries were clavicle fractures (32%), followed by acromioclavicular joint dislocations (22%), rotator cuff tears (22%), and humeral fractures (8%). Fifty-one percent of subjects were managed with conservative care and the remaining patients required surgical interventions. CONCLUSIONS Shoulder injuries incurred while riding a bicycle span the entire spectrum of shoulder injuries and often result in debilitating conditions. Although the use of helmets is increasing, there is currently no effective protective gear or measures to prevent riders from suffering shoulder injuries.

Abstract
Excision of the proximal femur for tumour with prosthetic reconstruction using a bipolar femoral head places a considerable load on the unreplaced acetabulum. We retrospectively reviewed the changes which occur around the affected hip joint by evaluating the post-operative radiographs of 65 consecutive patients who underwent proximal prosthetic arthroplasty of the femur, and in whom an acetabular component had not been used. There were 37 men and 28 women with a mean age of 57.3 years (17 to 93). Radiological assessment included the extent of degenerative change in the acetabulum, heterotopic ossification, and protrusio acetabuli. The mean follow-up was 9.1 years (2 to 11.8). Degenerative changes in the acetabulum were seen in three patients (4.6%), Brooker grade 1 or 2 heterotopic ossification in 17 (26%) and protrusion of the prosthetic head in nine (13.8%). A total of eight patients (12.3%) needed a revision. Five were revised to the same type of prosthesis and three (4.6%) were converted to a total hip arthroplasty. We conclude that radiological evidence of degenerative change, heterotopic ossification and protrusion occur in a few patients who undergo prosthetic arthroplasty of the proximal femur for tumour. The limited extent of these changes and the lack of associated symptoms do not justify the routine arthroplasty of the acetabulum in these patients. Cite this article: Bone Joint J 2015;97-B:1704–9

Platelet-rich plasma did not improve early healing of medial collateral ligament in rats. Arch Orthop Trauma Surg 2015; 135:1571-7. [PMID: 26298561 DOI: 10.1007/s00402-015-2306-7] [Citation(s) in RCA: 10] [Impact Index Per Article: 1.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/10/2014] [Indexed: 01/08/2023]
Abstract
BACKGROUND The medial collateral ligament (MCL) is the most frequently injured ligament of the knee. Platelet-rich plasma (PRP) is a relatively new treatment option developed to enhance the healing response after injury to different tissue types. This study aimed at investigating whether the addition of PRP to MCL tears in rats would alter healing both biomechanically and histologically. METHODS Bilateral full-thickness tears of the MCL were surgically induced in the knees of 32 rats. Right ligament was saturated with PRP (n = 32, study group), and the left ligament was saturated with saline (n = 32, control group). The animals were killed 3 weeks later and the surgical sites were evaluated by gross inspection, biomechanically and histologically. RESULTS There was no gross difference in the mass of granulation tissue, load to failure, stiffness and displacement between the study and control groups. Histological examination by means of maturity score revealed no significant differences between the study and control groups. CONCLUSION The addition of PRP to a healing MCL did not improve any of the outcome measures in this model.

Abstract
Heterotopic ossification (HO) after hip arthroscopy is the abnormal formation of mature lamellar bone within extra skeletal soft tissues. HO may lead to pain, impaired range of motion and possibly revision surgery. There has been a substantial amount of recent research on the pathophysiology, prophylaxis and treatment of HO associated with open and arthroscopic hip surgery. This article reviews the literature on the aforementioned topics with a focus on their application in hip arthroscopy.

Protective effects of rosuvastatin in a rat model of lung contusion: Stimulation of the cyclooxygenase 2-prostaglandin E-2 pathway. Surgery 2015; 157:944-53. [PMID: 25724093 DOI: 10.1016/j.surg.2014.12.017] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/07/2014] [Revised: 12/16/2014] [Accepted: 12/24/2014] [Indexed: 11/24/2022]
Abstract
BACKGROUND Lung contusion, which can occur in patients with blunt thoracic trauma, is a leading risk factor for development of acute lung injury (ALI) and acute respiratory distress syndrome. Statins are lipid-lowering drugs with many beneficial antiinflammatory and antioxidative effects. We therefore hypothesized that the administration of statins immediately after trauma will inhibit the production of inflammatory mediators, and thereby alleviate the severity of lung injury. METHODS A model of blunt chest injury in rat was employed. The effects of statins (rosuvastatin) and cyclooxygenase-2 (COX-2) inhibitors (meloxicam) on ALI were assessed by measuring inflammatory mediator levels in the serum and in the bronchoalveolar space. Animals were killed at the end of day 3. Histologic evaluation of lung tissue was performed to confirm the presence and severity of lung contusion as well as the effects of statins, nonsteroidal antiinflammatory drugs, and their combination. RESULTS Administration of meloxicam after lung contusion decreased the amount of neutrophil infiltration; however, marked hemorrhage and edema were still noticed. Administration of rosuvastatin decreased significantly cytokine levels that were increased after the blunt chest trauma. Rosuvastatin increased the expression of inducible nitric oxide (iNOS), COX-2, heme oxygenase-1 (HO-1), and prostaglandin E2 (PGE-2) in the bronchoalveolar lavage fluid of the rat contused lungs. Coadministration of meloxicam prevented these changes. CONCLUSION Rosuvastatin treatment after lung contusion attenuated several features of ALI. The enhanced activity of iNOS, COX-2, and HO-1 in the lung may reflect the advent of protective processes that took place in the contused lung. To our knowledge, this is the first demonstration that prostaglandin pathways play an essential role in the effects of statins in lung injury.

Capsular closure does not affect development of heterotopic ossification after hip arthroscopy. Arthroscopy 2015; 31:225-30. [PMID: 25442652 DOI: 10.1016/j.arthro.2014.08.026] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/04/2014] [Revised: 08/12/2014] [Accepted: 08/26/2014] [Indexed: 02/02/2023]
Abstract
PURPOSE The purpose of this study was to evaluate the role of capsular closure after hip arthroscopy in reduction of the incidence of heterotopic ossification (HO). METHODS One hundred (50 study group, 50 control group) consecutive hip arthroscopy procedures with radiographic follow-up of more than 9 weeks were included in the study. The study group consisted of 50 patients in whom capsular closure with 2 No. 1 polydioxanone (PDS) sutures was performed, and a control group consisted of 50 patients in whom the capsule remained open after capsulotomy. HO was assessed by radiographs using the Brooker classification. Statistical analysis of the data was carried out with the χ-square or Fisher exact test and Student t test, when appropriate, at a significance level of .05. RESULTS Thirty-six (36%) patients had radiographic evidence of postoperative HO (14 patients in the capsular closure group). No significant difference was found regarding sex, side of operation, age, or HO rate between the study and the control groups (P = .778, P = .123, P = .744, and P = .144, respectively). Furthermore, no significant difference was found in the rate of HO with potential clinical significance (Brooker classification > I) between the control and study groups (P = .764). CONCLUSIONS Capsular closure did not seem to alter the rate of HO when compared with a control group of patients in whom the capsulotomy was not repaired. LEVEL OF EVIDENCE Level III, retrospective comparative study.
