Psychological symptoms and the MCID of the DASH score in shoulder surgery

The timed 100 mL water swallow test for patients with head and neck cancer: What constitutes a clinically significant difference?

OBJECTIVES

Swallowing function in patients with head and neck cancer (HNC) is often assessed pre-treatment, during and at intervals post-treatment to identify those with dysphagia as early as possible. This study aims to investigate the minimal clinical important difference (MCID) for the 100 mL water swallow test (100 mL WST) to increase its utility in clinical practice and in clinical trials.

METHODS

Data from 211 HNC patients, treated by either single or combined modality were included. Patients completed both the 100 mL WST and M.D. Anderson Dysphagia Inventory (MDADI) at baseline (i.e., prior to treatment) and 12 months post-treatment. The MCID for the 100 mL WST was calculated using two approaches of the anchor-based method (using the MDADI), including mean change, and ROC curve. Additionally, the distribution-based method was used utilizing the half standard deviation approach.

RESULTS

In the anchor-based method, a 4 mL/s in the 100 mL WST was defined as an MCID for deterioration, with a sensitivity of 75% and a 1-specificity of 46%. In contrast, a change of 5 mL/s was deemed as an MCID for improvement, based on the distribution-based method.

CONCLUSION

The findings showed that deterioration of 4 mL, or an increase of 5 mL from baseline to 12 months post-HNC treatment equates to an MCID from the patients' perspective. Based on these findings, it may be beneficial to increase the utilization of the 100 mL WST in clinical practice to observe the changes, and in clinical trials to interpret and compare different study arms.

Patients with rotator cuff tears present a psychological impairment, not only a functional deficit: a systematic review

INTRODUCTION

Psychological factors impact patients with rotator cuff tears (RCT) in terms of pain level, shoulder function, sleep disturbance, and quality of life (QoL). The aim of this study was to quantify the prevalence of psychological factors in those patients, evaluate their influence on patient-reported outcomes (PROMs), and assess the possible improvement with surgical treatment.

METHODS

The literature search was performed on PubMed, Web of Science, Wiley Cochrane Library up to January, 2023.

INCLUSION CRITERIA

RCT treated with arthroscopic rotator cuff reconstruction (ARCR), description of psychological variables evaluated with validated questionnaires, descriptions of PROMs.

RESULTS

Thirty-nine studies included 7021 patients. Depression was found in eight studies (19.2%), anxiety in 6 (13.0%), sleep disturbance in seven (71.3%), and distress in three studies (26.4%). Studies evaluating the relationship between psychological impairment and pain documented more pain and impaired shoulder function before and after ARCR in patients with altered psychological status.

DISCUSSION

An impaired psychological status has an important impact on patients' perception of their disease. RCT patients with psychological alterations often experience more pain and reduced shoulder function, thus having worse QoL.

CONCLUSION

This study underlines that psychological impairment largely affects RCT patient condition and treatment outcome, which underlines the importance of a multidisciplinary biopsychosocial intervention to achieve better results.

A novel surgical method for treating fractures of the middle third of the clavicle

BACKGROUND

The clavicle is recognized as the bone most vulnerable to fractures. Moreover, approximately 80% of fractures occur in the middle third of the clavicle. Conservative treatment is associated with a higher rate of nonunion, while surgical treatment of fracture via internal fixation may have a variety of postoperative complications. Therefore, to improve patient satisfaction and reduce the complications related to internal fixation techniques, we modified the surgical approach to external fixation.

OBJECTIVE

The purpose of this study was to assess the modified intervention's prospects for clinical application.

METHODS

A total of 36 patients with middle clavicle fractures were treated with screw-rod external fixation between April 2015 and October 2019. We observed the operative time, intraoperative blood loss, length of hospital stay, and fracture healing time. The patients were followed up regularly, and the clinical efficacy of the modified intervention was evaluated. Finally, the patients' shoulder function was assessed based on the disabilities of the arm, shoulder, and hand (DASH) score.

RESULTS

For the screw-rod external fixation, the mean operative time was found to be 48.6 ± 6.8 min, the intraoperative blood loss was 30.6 ± 17.2 mL, the length of hospital stay was 4.5 ± 1.5 days, and the fracture healing time was 2.8 ± 0.4 months. Eventually, all the patients healed well, with the combined "excellent" and "good" rate of shoulder function being assessed to be as high as 94.44%. Furthermore, the DASH scores were all less than 10, with the average score being 4.65 ± 3.34.

CONCLUSIONS

The screw-rod external fixation technique offers the advantages of convenience, reliability, and good aesthetics, suggesting that it could be used as an alternative treatment method for fractures of the middle third of the clavicle.

Quality of Life and Pain after Proximal Humeral Fractures in the Elderly: A Systematic Review

Background and Objectives: The proximal humeral fracture (PHF) is one of the most common fractures in elderly patients. A PHF might influence the quality of life (QoL) on several different levels, especially in elderly patients, but it is unclear which treatment option results in a better QoL outcome. Therefore, we aimed to systematically review the current literature for studies that have analyzed the QoL and pain of elderly patients treated either surgically or non-operatively for PHF. Materials and Methods: A comprehensive search of the literature was performed in the PubMed database from January to April 2023. Studies describing the QoL or the level of pain of patients older than 60 years with the EuroQoL-5 Dimension (EQ-5D) score or the visual analogue scale (VAS) after the treatment of PHF, either non-operatively (non-OP), with open-reduction and internal fixation using a locking plate (LPF), or with reverse total shoulder arthroplasty (RTSA) were included. Twelve studies were analyzed descriptively and the individual risk of bias was assessed using the ROB2 and ROBINS-I tools. Results: A total of 12 studies with 712 patients at baseline were included (78% female sex, mean age 75.2 years). The reported VAS scores at 12-month follow-up (FU) ranged from 0.7 to 2.5. The calculated overall mean VAS score across all studies showed a decreasing tendency for all treatments, with an increasing FU time up to 12 months after PHF. None of the studies reported any significant differences of the EQ-5D across the groups. The overall calculated EQ-5D indices showed an increasing trend after 6-8 weeks FU, but did not differ significantly between the three treatments. Conclusions: In conclusion, the current literature suggests that there are no clinically important differences between the QoL or pain in elderly patients with PHF after non-operative treatment or surgical treatment with LPF or RTSA. However, the number of studies and level of evidence is rather low and further trials are urgently needed.

Should we separately measure the pain parameter of the Constant-Murley score in patients with chronic shoulder pain?

BACKGROUND

The Constant-Murley Score (CMS) is a relatively unique shoulder assessment tool because it combines patient-reported outcomes (pain and activity), performance measurement and clinician-reported outcomes (strength and mobility). With these characteristics, the effect of patient-related psychological factors on the CMS remains debated. We aimed to investigate which parameters of the CMS are influenced by psychological factors by assessing the CMS before and after rehabilitation for chronic shoulder pain.

METHODS

This retrospective study screened all patients (18-65 years old) who were admitted for interdisciplinary rehabilitation for chronic shoulder pain (≥ 3 months) between May 2012 and December 2017. Patients with unilateral shoulder injuries were eligible. Exclusion criteria were shoulder instability, concomitant neurological injuries, complex regional pain syndrome (including Steinbrocker syndrome), heavy psychiatric issues, and missing data. The Hospital Anxiety and Depression Scale, Pain Catastrophizing scale, and Tampa Scale of Kinesiophobia were administered before and after treatment. Regression models were used to estimate associations between psychological factors and the CMS.

RESULTS

We included 433 patients (88% male, mean age 47±11 years) with a median duration of symptoms of 392.2 days (interquartile range: 266.5-583.5). Rotator cuff issue was present in 71% of patients. During interdisciplinary rehabilitation, patients were followed for a mean of 33.6±7.5 days. The mean CMS at entry was 42.8 ±15.5. The mean gain in CMS after treatment was 10.6 ±10.9. Before treatment, psychological factors were significantly associated with only the pain CMS parameter: -0.37 (95% CI: -0.46 to -0.28), p <0.001. After treatment, psychological factors were associated with the evolution of the four CMS parameters: -0.12 (-0.23 to -0.01) to -0.26 (95% CI: -0.36 to -0.16), p<0.05.

CONCLUSIONS

This study raises the question of a distinct assessment of pain when assessing shoulder function with CMS in patients with chronic shoulder pain. The separation of the "pain parameter" from the overall CMS score seems illusory with this tool that is used worldwide. However, clinicians should be aware that psychological factors can negatively influence the evolution of all CMS parameters during follow-up, which argues for a biopsychosocial approach to patients with chronic shoulder pain.

What Is the Clinical Benefit of Common Orthopaedic Procedures as Assessed by the PROMIS Versus Other Validated Outcomes Tools?

BACKGROUND

Patient-reported outcome measures (PROMs), including the Patient-reported Outcomes Measurement Information System (PROMIS), are increasingly used to measure healthcare value. The minimum clinically important difference (MCID) is a metric that helps clinicians determine whether a statistically detectable improvement in a PROM after surgical care is likely to be large enough to be important to a patient or to justify an intervention that carries risk and cost. There are two major categories of MCID calculation methods, anchor-based and distribution-based. This variability, coupled with heterogeneous surgical cohorts used for existing MCID values, limits their application to clinical care.

QUESTIONS/PURPOSES

In our study, we sought (1) to determine MCID thresholds and attainment percentages for PROMIS after common orthopaedic procedures using distribution-based methods, (2) to use anchor-based MCID values from published studies as a comparison, and (3) to compare MCID attainment percentages using PROMIS scores to other validated outcomes tools such as the Hip Disability and Osteoarthritis Outcome Score (HOOS) and Knee Disability and Osteoarthritis Outcome Score (KOOS).

METHODS

This was a retrospective study at two academic medical centers and three community hospitals. The inclusion criteria for this study were patients who were age 18 years or older and who underwent elective THA for osteoarthritis, TKA for osteoarthritis, one-level posterior lumbar fusion for lumbar spinal stenosis or spondylolisthesis, anatomic total shoulder arthroplasty or reverse total shoulder arthroplasty for glenohumeral arthritis or rotator cuff arthropathy, arthroscopic anterior cruciate ligament reconstruction, arthroscopic partial meniscectomy, or arthroscopic rotator cuff repair. This yielded 14,003 patients. Patients undergoing revision operations or surgery for nondegenerative pathologies and patients without preoperative PROMs assessments were excluded, leaving 9925 patients who completed preoperative PROMIS assessments and 9478 who completed other preoperative validated outcomes tools (HOOS, KOOS, numerical rating scale for leg pain, numerical rating scale for back pain, and QuickDASH). Approximately 66% (6529 of 9925) of patients had postoperative PROMIS scores (Physical Function, Mental Health, Pain Intensity, Pain Interference, and Upper Extremity) and were included for analysis. PROMIS scores are population normalized with a mean score of 50 ± 10, with most scores falling between 30 to 70. Approximately 74% (7007 of 9478) of patients had postoperative historical assessment scores and were included for analysis. The proportion who reached the MCID was calculated for each procedure cohort at 6 months of follow-up using distribution-based MCID methods, which included a fraction of the SD (1/2 or 1/3 SD) and minimum detectable change (MDC) using statistical significance (such as the MDC 90 from p < 0.1). Previously published anchor-based MCID thresholds from similar procedure cohorts and analogous PROMs were used to calculate the proportion reaching MCID.

RESULTS

Within a given distribution-based method, MCID thresholds for PROMIS assessments were similar across multiple procedures. The MCID threshold ranged between 3.4 and 4.5 points across all procedures using the 1/2 SD method. Except for meniscectomy (3.5 points), the anchor-based PROMIS MCID thresholds (range 4.5 to 8.1 points) were higher than the SD distribution-based MCID values (2.3 to 4.5 points). The difference in MCID thresholds based on the calculation method led to a similar trend in MCID attainment. Using THA as an example, MCID attainment using PROMIS was achieved by 76% of patients using an anchor-based threshold of 7.9 points. However, 82% of THA patients attained MCID using the MDC 95 method (6.1 points), and 88% reached MCID using the 1/2 SD method (3.9 points). Using the HOOS metric (scaled from 0 to 100), 86% of THA patients reached the anchor-based MCID threshold (17.5 points). However, 91% of THA patients attained the MCID using the MDC 90 method (12.5 points), and 93% reached MCID using the 1/2 SD method (8.4 points). In general, the proportion of patients reaching MCID was lower for PROMIS than for other validated outcomes tools; for example, with the 1/2 SD method, 72% of patients who underwent arthroscopic partial meniscectomy reached the MCID on PROMIS Physical Function compared with 86% on KOOS.

CONCLUSION

MCID calculations can provide clinical correlation for PROM scores interpretation. The PROMIS form is increasingly used because of its generalizability across diagnoses. However, we found lower proportions of MCID attainment using PROMIS scores compared with historical PROMs. By using historical proportions of attainment on common orthopaedic procedures and a spectrum of MCID calculation techniques, the PROMIS MCID benchmarks are realizable for common orthopaedic procedures. For clinical practices that routinely collect PROMIS scores in the clinical setting, these results can be used by individual surgeons to evaluate personal practice trends and by healthcare systems to quantify whether clinical care initiatives result in meaningful differences. Furthermore, these MCID thresholds can be used by researchers conducting retrospective outcomes research with PROMIS.

ICON 2020-International Scientific Tendinopathy Symposium Consensus: A Scoping Review of Psychological and Psychosocial Constructs and Outcome Measures Reported in Tendinopathy Clinical Trials

OBJECTIVE

To identify and describe the psychological and psychosocial constructs and outcome measures used in tendinopathy research.

DESIGN

Scoping review.

LITERATURE SEARCH

We searched the PubMed, EMBASE, Scopus, Web of Science, PEDro, CINAHL, and APA PsychNet databases on July 10, 2021, for all published studies of tendinopathy populations measuring psychological and psychosocial factors.

STUDY SELECTION

Studies using a clinical diagnosis of tendinopathy or synonyms (eg, jumper's knee or subacromial impingement) with or without imaging confirmation.

DATA SYNTHESIS

We described the volume, nature, distribution, and characteristics of psychological and psychosocial outcomes reported in the tendinopathy field.

RESULTS

Twenty-nine constructs were identified, including 16 psychological and 13 psychosocial constructs. The most frequently-reported constructs were work-related outcomes (32%), quality of life (31%), depression (30%), anxiety (18%), and fear (14%). Outcome measures consisted of validated and nonvalidated questionnaires and 1-item custom questions (including demographics). The number of different outcome measures used to assess an individual construct ranged between 1 (emotional distress) and 11 (quality of life) per construct.

CONCLUSION

There was a large variability in constructs and outcome measures reported in tendinopathy research, which limits conclusions about the relationship between psychological and psychosocial constructs, outcome measures, and tendinopathies. Given the wide range of psychological and psychosocial constructs reported, there is an urgent need to develop a core outcome set in tendinopathy.

Are short press-fit stems comparable to standard-length cemented stems in reverse shoulder arthroplasty? A prospective, randomized clinical trial

BACKGROUND

The literature comparing humeral implants in reverse shoulder arthroplasty is sparse. With minimal supporting literature, there has been a trend away from standard-length cemented humeral implants to press-fit stems and, recently, to shorter-stem implants. It is known that early implant migration, within the first 2 years postoperatively, is predictive of later implant loosening and possible revision surgery. Therefore, the purpose of this study was to compare clinical outcomes and implant migration between cemented standard-length humeral stems and press-fit short stems using model-based radiostereometric analysis.

METHODS

After a power analysis, 41 shoulders were prospectively randomized to receive either a cemented standard-length or press-fit short humeral stem for primary reverse shoulder arthroplasty between July 2017 and June 2019. Following surgery, participants were imaged with stereo radiographs acquired at 6 weeks (baseline), 3 months, 6 months, 1 year, and 2 years. Migration of the humeral stem at each time point was compared with baseline, with differences in migration between cohorts assessed using a mixed-effects model with the Bonferroni test for multiple comparisons. Patient-reported outcome measures (Subjective Shoulder Value; American Shoulder and Elbow Surgeons shoulder score; Simple Shoulder Test score; Disabilities of the Arm, Shoulder and Hand score; and Constant score) were also compared.

RESULTS

At 6 months (P = .025), 1 year (P = .004), and 2 years (P = .001) postoperatively, press-fit short stems migrated significantly more than cemented stems along the superior-inferior translation axis; in addition, they showed greater total translation at 2 years (P = .003). Mean total translation (± standard deviation) at 2 years was 0.4 ± 0.2 mm and 1.0 ± 1.1 mm for the cemented and press-fit cohorts, respectively. Mean migration between the 1- and 2-year time points was minimal for both stem fixation groups along all axes (<0.1 mm and 0.6°). There was no difference in active range of motion, pain, or validated outcome measures between the cohorts at 2 years (P ≥ .170).

CONCLUSION

This randomized clinical trial shows that press-fit short humeral stems subside substantially more than standard-length cemented stems but ultimately achieve stability from 1 year through 2 years. Conversely, no significant differences were observed in clinical outcomes between cohorts.

Arthroscopic debridement for management of massive, irreparable rotator cuff tears: a systematic review of outcomes

Background

Surgical management of massive irreparable rotator cuff tears remains controversial. Arthroscopic debridement (AD) has shown promising results especially in the population older than 65 years; however, there is no consensus on the benefits of various AD procedures. The aim of this systematic review was to evaluate the functional midterm to long-term outcomes in patients treated with AD in combination with subacromial decompression, biceps tenotomy, tuberoplasty, or bursectomy, without repair of the rotator cuff tear.

Methods

A comprehensive search was performed in PubMed, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Cochrane databases for studies reporting clinical outcomes of AD of massive rotator cuff tears. Quality was determined using the Methodological Index for Nonrandomized Studies (MINORS) criteria by two independent reviewers. Pooled frequency-weighted means and standard deviations were calculated for patient-reported outcomes.

Results

Sixteen articles containing 643 patients and 662 shoulders met the eligibility criteria. The mean age at the time of surgery was 65.9 ± 4.4 years with a mean follow-up period of 46.5 ± 27.3 months. There was notable clinically significant improvement across all patient-reported outcome scores postoperatively: Constant 70.4 ± 8.9 (P value = .06), University of California, Los Angeles ultrasonography 26.7 ± 5.2 (P value = .001), American Shoulder and Elbow Surgeons score 71.7 ± 2.1 (P value = .12), Disabilities of the Arm, Shoulder, and Hand score 35.3, and visual analog score 1.7 ± 0.9. Forty-nine patients (7%) required reoperation, which most commonly was a reverse total shoulder arthroplasty for the development of rotator cuff arthropathy.

Conclusion

Arthroscopic debridement with a combination of subacromial decompression, tuberoplasty, subacromial bursectomy, and biceps tenotomy, for treatment of massive irreparable rotator cuff tears, produces good functional outcomes and improvement in pain at mid to long term follow up for the low-demand population greater than 65 years of age looking for pain relief over substantial increase in function.

Role of strengthening during nonoperative treatment of lateral epicondyle tendinopathy

INTRODUCTION

Lateral epicondyle tendinopathy (LET) is the most common cause of lateral elbow pain. The literature on rehabilitation of the condition encompasses a plethora of interventions with most current evidence indicating that stretches and some form of strengthening are vital components. However, patient outcomes are infrequently reported further than 12 weeks from the start of therapy and it is unclear which components of a home exercise program are necessary to alleviate symptoms up to one year from the initiation of a therapy program.

PURPOSE OF THE STUDY

The purpose of the study is to determine if a therapy program with 4 to 6 visits spaced out over 12 weeks focusing on self-management and strengthening is more effective in reducing pain and improving function long term than the same program without strengthening, for individuals with LET.

STUDY DESIGN

This is a randomized controlled trial.

METHODS

Ninety-four patients were randomly allocated into two groups: both groups received the interventions of education in pertinent pathoanatomy, stretching, pain management through rest and icing, and activity modification. Group 1 (n = 38) was also provided with a strengthening component to the home exercise program, whereas group 2 did not (n = 21). Our primary outcome measure was pain at rest and pain with activity; our secondary measure was the level of functional impairment as measured by the quick disabilities of arm shoulder and hand. Outcome measurements were assessed at baseline, 6, 12, 24, and 52 weeks after initiation of therapy.

RESULTS

Both groups demonstrated statistically significant improvement with a moderate to large effect size in pain and function scores when compared with previous time point at 6, 12, and 24 weeks. Pain continued to decrease for both groups from 24 weeks to 52 weeks, but interestingly, there was a significant increase with moderate effect size in the quick disabilities of arm shoulder and hand score at 52 weeks when compared with week 24. No statistically significant difference was found between the two groups at any time point up to 52 weeks from the start of therapy.

CONCLUSIONS

This study demonstrates that a therapy program consisting of a low number of visits spaced out over 12 weeks based on education, stretches, activity modification, and pain management techniques is effective at reducing pain and increasing function in patients with LET. The addition of strengthening to this program did not improve outcomes. The therapy approach used in this study is consistent with the International Classification of Function guidelines and focuses on engaging patients in self-management of the condition through patient education and self-empowerment.

Traumatic Brachial Plexus Injury in Indonesia: An Experience from a Developing Country

Background  Brachial plexus injuries (BPI) cause severe physical disability and major psycho-socioeconomic burden. Although various countries have reported BPI incidence, the data from Indonesia as the fourth most populated country in the world remains unknown. We aim to assess the distribution of traumatic BPI, patients' characteristics, and treatment modalities in Indonesia.

Methods  A retrospective investigation was performed comprising 491 BPI patients at a tertiary referral hospital in Indonesia from January 2003 to October 2019. Demographic and outcomes data were retrieved from medical records.

Results  The average BPI patients' age was 27.3 ± 11.6 years old, with a male/female ratio of 4.6:1. Motorcycle accidents caused the majority (76.1%) of all BPI cases. Concomitant injuries were present in 62.3% of patients, dominated by fractures (57.1%) and brain injuries (25.4%). BPI lesion type was classified into complete (C5-T1, observed in 70% patients), upper (C5-C6, in 15% patients), extended upper (C5-C7, in 14% patients), and lower type (C8-T1, in 1% patients). The average time to surgery was 16.8 months (range 1–120 months), with the majority (76.6%) of the patients was operated on six months after the trauma. Free functional muscle transfer (FFMT) was the most common procedure performed (37%). We also analyzed the functional outcomes (active range of motion (AROM) and muscle power), DASH (Disabilities of the Arm, Shoulder, and Hand) score, and VAS (Visual Analogue Scale) across four most frequent procedures involving nerve reconstruction (FFMT, nerve transfer, external neurolysis, and nerve grafting). We found that FFMT was significantly better than nerve transfer in terms of DASH score and VAS ( p  = 0.000 and p  = 0.016, respectively) in complete BPI (C5-T1). Moreover, we also found that nerve grafting resulted in a significantly better shoulder abduction AROM than nerve transfer and external neurolysis in extended upper BPI (C5-C7) ( p  = 0.033 and p  = 0.033, respectively). Interestingly, no significant differences were observed in other measurements.

Conclusion  This study provides an overview of traumatic BPI patients in a single tertiary trauma center in Indonesia, expressing the profile of their characteristics and functional outcomes after surgical procedures.

Homemade 3D mirror imaging models utility for surgical treatment of complex fractures of scapula

The treatment of complex articular scapular fractures requires obtaining an anatomic reduction. The experience of the surgeon and the surgical skills needed are still the most important aspect in this surgical field. 3D printed models at a 1:1 scale provides tactile and visual experience. We used a specular healthy scapula (reverse engineering) as a reliable template for preoperative planning. We pre-contour plates directly over a printed mold, for direct application, without further corrections during the surgical procedure. This reduces improvisation during surgery, the risks of complications and the total costs while improving the accuracy of the anatomical restoration of the native glenopolar angle derived from the indirect reduction of the fracture. Until recently, the use of RP (rapid prototyping) models for managing complex fractures required contracting the services provided by external companies, with the constraints posed on cost and time. We made the whole process ourselves in a DIY mode: from the post-processed radiological images to the 3D model printing, pre contoured plates and surgical simulation.

Arthroscopic Autologous Scapular Spine Bone Graft Combined With Bankart Repair for Anterior Shoulder Instability With Subcritical (10%-15%) Glenoid Bone Loss

PURPOSE

The purpose of our study is to prove that the autologous scapular spine bone graft is an alternative for the treatment of anterior shoulder instability and the clinical and radiological results are promising.

METHOD

From July 2016 to August 2018, patients who were diagnosed as having anterior shoulder instability with subcritical (10%-15%) glenoid bone loss were treated by arthroscopic repair with autologous scapular spine bone graft. The inclusion criteria were (1) anterior shoulder instability underwent arthroscopic autologous scapular spine bone graft; (2) glenoid bone loss was within 10% to 15% (measured by Sugaya's method); (3) three complete sets of computed tomography (CT) scans (preoperative, 1 week after surgery, and 1 year after surgery) available; and (4) clinical follow-up time was at least 2 years. The exclusion criteria were (1) concomitant rotator cuff tear; (2) concomitant remplissage or SLAP repair; (3) previous surgery of the affected shoulder; (4) open surgery; and (5) incomplete radiological or clinical follow-up. The preoperative and postoperative Constant-Murley score, dietary approaches to stop hypertension (DASH) score, visual analog scale (VAS) score, and range of motion (ROM) were recorded. CT scans with 3-dimensional reconstruction were obtained at the first week after operation and at 1 year after operation; the graft resorption rate was consequently calculated.

RESULTS

Twenty-seven patients were qualified and enrolled in the study. No severe complication was recorded during follow-up. No redislocation or subluxation was found, and the apprehension tests were all negative. At the last follow-up, the mean Constant-Murley score was 89.74 ± 3.71, the mean DASH score was 9.77 ± 5.31, the mean VAS score was 0.74 ± 0.64, which are all improved significantly compared with preoperative scores (P = .00,.00,.00, respectively). At the last follow-up, the ROM including anterior flexion, external rotation by side, and the internal rotation were well restored without significant difference compared with the contralateral shoulder (P =.48, .08, .47, respectively). At 1 year after operation, the resorption rate of the bone graft was 19.4%.

CONCLUSION

This study found that anterior shoulder instability with subcritical (10%-15%) glenoid bone loss treated with arthroscopic autologous scapular spine bone graft with suture anchor fixation is safe and could achieve satisfactory result at short-term follow-up.

Do psychological factors affect outcomes in musculoskeletal shoulder disorders? A systematic review

Background

Psychological factors may impact recovery in patients undergoing treatment for shoulder complaints. The aim of this review is to systematically analyse the evidence for the effect of modifiable psychological factors (MPF) on outcome, for patients with musculoskeletal shoulder disorders undergoing conservative or surgical treatment. MPF refers to factors that may change with intervention.

Methods

This is a systematic literature review. Five databases searched (MEDLINE, CINAHL, Cochrane Library, Embase and PsycInfo), for longitudinal studies investigating the influence of MPF on prognosis of patients with shoulder disorders, all diagnoses, undergoing clinical interventions (conservative or surgical). Level of evidence was determined using Scottish Intercollegiate Guidelines Network (SIGN) methodology. Moderate and high quality evidence was included. We extracted all MPF, categorized constructs into the following domains: beliefs (self-efficacy, expectation of recovery), coping (catastrophizing, avoidant coping), and affect (depression, anxiety). We evaluated constructs for its predictive value of at least one outcome. Outcomes were informed by this review. Evidence was classified into three categories: evidence for, inconclusive evidence, and evidence against.

Results

Of 1170 references, 40 distinct publications based on 35 datasets were included (intervention type: 20 surgical; 20 conservative). Overall, 22 studies (20 cohort studies and 2 RCTs) were classified as high quality and 18 studies (16 cohort studies, 2 RCTs) were classified as moderate quality. Outcomes reported included pain, disability/function, perceived recovery, physical and mental health, and work status. Based on the review, of the psychological constructs explored, these data would suggest that expectation of recovery, catastrophizing, avoidant coping, depression, and anxiety may predict outcome for patients managed surgically. In patients undergoing conservative intervention the evidence was either against (catastrophizing, depression, anxiety) or inconclusive (self-efficacy, expectation of recovery, avoidant coping) for the predictive value of psychological factors on outcome.

Conclusions

Five constructs were predictive of outcome for surgically managed patients. This suggests that implementing the biopsychosocial approach (i.e., preoperative screening, intervention by a trained clinician) may be advantageous for patients recommended for shoulder surgery,,. The same is not indicated for conservatively managed patients as no conclusive association of MPF with outcomes was noted. The importance of other MPF on outcome requires further investigation.

The Relationship Between Fear Avoidance Beliefs, Muscle Strength, and Short-Term Disability After Surgical Repair of Shoulder Instability

CONTEXT

Arthroscopic surgical repair of the shoulder is recommended when conservative treatment for shoulder instability (SI) fails. However, many patients undergoing this procedure do not return to same level of activity. Psychological factors and muscle strength have been shown to be associated with postoperative outcomes in other musculoskeletal conditions.

OBJECTIVE

To investigate the association between fear avoidance, muscle strength, and short-term function in patients after surgical SI repair.

METHODS

Twenty-five male patients who underwent shoulder surgery following at least one event of SI were included in this study. Evaluations of fear avoidance related to physical activity and disability were performed at baseline (during the first encounter with the physical therapist) and 7 to 8 weeks postsurgery. Fear avoidance beliefs were assessed using the Fear Avoidance Beliefs Questionnaire. Disability was assessed using the Disabilities of Arm, Shoulder, and Hand questionnaire and the Western Ontario SI index. The follow-up evaluation (weeks 7-8) included measurement of maximal isometric strength of the internal and external rotators. Nonparametric Kendall tau was used to determine the correlations between baseline fear avoidance, muscle strength, and disability at follow-up.

RESULTS

Disabilities of Arm, Shoulder, and Hand questionnaire at follow-up was significantly correlated with baseline Disabilities of Arm, Shoulder, and Hand questionnaire (τ = .520, P < .001), baseline fear avoidance (τ = .399, P = .008), and both internal rotator (τ = -.400, P = .005) and external rotator strength (τ = -.353, P = .014). Western Ontario SI index at follow-up was moderately correlated with baseline Western Ontario SI index (τ = .387, P = .007), internal rotator (τ = -.427, P = .003), and external rotator (τ = -.307, P = .032), but not with baseline Fear Avoidance Beliefs Questionnaire (τ = .22, P = .145).

CONCLUSIONS

The results indicate a possible association between fear avoidance beliefs and short-term disability. Further studies are warranted to better explore and understand these relationships.

Minimal Clinically Important Difference, Substantial Clinical Benefit, and Patient Acceptable Symptom State of Outcome Measures Relating to Shoulder Pathology and Surgery: a Systematic Review

PURPOSE OF THE REVIEW

To provide a comprehensive summary of available literature on the minimal clinically important difference (MCID), substantial clinical benefit (SCB), and patient acceptable symptom state (PASS) of patient-reported outcome measures (PROMs) for various shoulder conditions and outcomes and to identify factors that influence these metrics.

RECENT FINDINGS

Over the past 2 years, there has been an increasing interest in utilizing MCID, SCB, and PASS as a gauge to evaluate the success of an intervention for shoulder conditions. Efforts at calculating these thresholds have yielded multiple and inconsistent values and are further compounded by the proliferation of different PROMs in the shoulder literature. The MCID, SCB, and PASS values of shoulder PROMs vary widely with study-specific characteristics, including patient demographics, shoulder pathology, treatment, shoulder instrument, study methodology, and calculation method. The differences in these factors are not inconsequential and could lead to large discrepancies in threshold values. It is crucial that clinicians are mindful of these variables when designing future studies to calculate these metrics or when utilizing previously published values to determine the success of an intervention.

Utility of Percutaneous Ultrasonic Tenotomy for Tendinopathies: A Systematic Review

CONTEXT

Chronic tendinopathy is a challenging problem that can lead to significant disability and limitation in not only athletics but also activities of daily living. While there are many treatment techniques described for this overuse injury, no single modality has been proven superior to all others. With recent advances in medical technology, percutaneous ultrasonic tenotomy (PUT) for tendinosis has gained traction with promising results.

OBJECTIVE

To examine the data published on PUT for treatment of tendinopathy, analyze the outcomes of the procedure, including duration of pain relief and patient-reported outcomes, and assess the rate of complications associated with the procedure.

DATA SOURCES

PubMed, MEDLINE, EMBASE, and Google Scholar.

STUDY SELECTION

The following combination of keywords was entered into the electronic search engines: ultrasonic tenotomy, ultrasound tenotomy, Tenex, and ultrasonic percutaneous tenotomy. The search results were screened for studies relevant to the topic. Only English-language studies were considered for inclusion. Studies consisting of level 4 evidence or higher and those involving human participants were included for more detailed evaluation.

LEVEL OF EVIDENCE

Level 4.

DATA EXTRACTION

Articles meeting the inclusion criteria were sorted and reviewed. Type of tendinopathy studied, outcome measures, and complications were recorded. Both quantitative and qualitative analyses were performed on the data collected.

RESULTS

There were a total of 7 studies that met the inclusion criteria and quality measures-5 studies involving the treatment of elbow tendinopathy and 1 study each involving the management of Achilles tendinopathy and plantar fasciitis. PUT resulted in decreased pain/disability scores and improved functional outcome scores for chronic elbow tendinopathy and plantar fasciitis. Results for Achilles tendinopathy showed modest improvement in the short term, but long-term data are lacking.

CONCLUSION

PUT is a minimally invasive treatment technique that can be considered in patients with tendinopathy refractory to conservative treatment measures. Further higher quality studies are necessary to accurately assess the comparative effectiveness of this treatment modality.

Responsiveness and minimal clinically important difference of the EQ-5D-5L in cervical intraepithelial neoplasia: a longitudinal study

Background

With the widespread clinical application of the five-level version of the EuroQol five-dimensional questionnaire (EQ-5D-5L), whether the questionnaire scores are responsive to changes in patients’ health and how much changes in questionnaire scores represent patients’ real health changes require consideration. Consequently, we assessed responsiveness and estimated the minimal clinically important difference (MCID) of the EQ-5D-5L in surgically treated patients with cervical intraepithelial neoplasia (CIN) to determine the relationship between MCID and minimal detectable change (MDC).

Methods

We conducted a longitudinal, observational study. Participants were patients with CIN from the gynecology inpatient department of a grade-A tertiary hospital in Shihezi, Xinjiang, China. Participants completed the EQ-5D-5L and the Global Rating of Change Questionnaire (GRCQ) at baseline and one month post-surgery. The Wilcoxon signed-rank test was used to compare EQ-5D-5L scores pre- and post-treatment. We calculated the effect size (ES) and the standardized response mean (SRM) to quantitatively assess responsiveness. Distribution-based, anchor-based, and instrument-defined methods were used to estimate MCID. MCID to MDC ratios at individual- and group-levels were also calculated.

Results

Fifty patients with CIN completed the follow-up investigation (mean age 44.76 ± 8.72 years; mean follow-up time 32.28 ± 1.43 days). The index value and EQ visual analogue scale (EQ VAS) of the EQ-5D-5L improved by 0.025 and 6.92 (all p < 0.05) at follow-up as compared to baseline respectively. The ES and the SRM of the index value were 0.47 and 0.42 respectively, indicating small responsiveness; while the ES and the SRM of EQ VAS were 0.50 and 0.49 respectively, indicating small to moderate responsiveness. The average (range) of MCIDs for index value and EQ VAS were 0.039 (0.023–0.064) and 5.35 (3.12–6.99) respectively. These values can only be used to determine whether patients have experienced clinically meaningful health improvements at the group level.

Conclusions

The EQ-5D-5L has only small to moderate responsiveness in post-surgical patients with CIN, and the MCIDs developed in this study can be used for group-level health assessment. However, further study is needed concerning health changes at the individual level.

Comparison between Two Methods to Evaluate Function in Postoperative Breast Cancer Survivors

INTRODUCTION

Treatment for breast cancer can cause adverse effects such as pain and reduced upper limb function which can affect activities of daily living. The Disabilities of the Arm, Shoulder and Hand (DASH) questionnaire is the most used tool for evaluating function in breast cancer survivors. However, some specific aspects have raised discussions about its restricted coverage, which can generate several biases.

OBJECTIVE

To determine if DASH scores differed when assessed before and after task-oriented training (TOT) at 3 and 6 months after breast cancer surgery.

DESIGN

Prospective cohort study.

SETTING

Institutional study of 22 women assessed at 3 and 6 months after breast cancer surgery.

MAIN OUTCOME MEASURES

The DASH questionnaire and TOT assessment. Two correlation tests were performed: Spearman's correlation between the total score of the two DASH scores (pre- and post-TOT) and the Kendall's tau correlation between each of the items.

RESULTS

There was a moderate and excellent correlation between final DASH scores, pre- and post-TOT, at both 3 and 6 months postoperatively. However, when assessed individually, most of the DASH items were poorly correlated. There was also no agreement between the total DASH scores pre- and post-TOT as assessed by Bland-Altman plots.

CONCLUSION

Both the DASH and TOT are considered useful in clinical practice to assess upper limb function, although the use of TOT in some of the DASH items may reduce memory bias and improve skills estimation.

Volar Locked Plating Versus Closed Reduction and Casting for Acute, Displaced Distal Radial Fractures in the Elderly: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

BACKGROUND

It remains unclear whether volar locked plating (VLP) yields a better functional outcome than closed reduction and casting (CRC) for elderly patients with an acute, displaced distal radial fracture. Our purpose was to conduct a systematic review and meta-analysis of randomized controlled trials comparing outcomes of VLP and CRC for elderly patients (age, ≥60 years).

METHODS

Multiple databases, including MEDLINE, were searched for randomized controlled trials evaluating outcomes following distal radial fracture treatment. Raw data were obtained for studies that included patients of all ages, and the elderly subgroup was included for analysis. The primary outcome was the Disabilities of the Arm, Shoulder and Hand (DASH) score at ≥1 year of follow-up. Secondary outcomes included the 3-month DASH score, range of motion, final radiographic alignment, and complications. Effect sizes for the comparison of each outcome between groups were pooled across studies using random-effects models with the inverse variance weighting method. Changes in DASH score were compared with a minimal clinically important difference (MCID) estimate of 10 to assess clinical relevance.

RESULTS

Of 2,152 screened articles, 6 were included. Demographics were similar for the 274 VLP and 287 CRC patients. DASH scores were significantly better following VLP than CRC at the time of final follow-up (12 to 24 months postoperatively; score difference, -5.9; 95% confidence interval [CI], -8.7 to -3.1) and at 3 months (-8.9; 95% CI, -13.0 to -4.8). VLP yielded significantly better palmar tilt, radial inclination, and supination, with no differences in ulnar variance, flexion-extension, pronation, or total complication rates.

CONCLUSIONS

Functional outcome was significantly better following VLP than CRC 3 months into the treatment of acute, displaced distal radial fractures in an elderly population and up to 2 years after injury. However, the observed differences in the final DASH score did not exceed published estimates of the MCID, suggesting that clinical outcomes are similar for both treatment options.

Operative versus non-operative treatment for 2-part proximal humerus fracture: A multicenter randomized controlled trial

BACKGROUND

Although increasingly used, the benefit of surgical treatment of displaced 2-part proximal humerus fractures has not been proven. This trial evaluates the clinical effectiveness of surgery with locking plate compared with non-operative treatment for these fractures.

METHODS AND FINDINGS

The NITEP group conducted a superiority, assessor-blinded, multicenter randomized trial in 6 hospitals in Finland, Estonia, Sweden, and Denmark. Eighty-eight patients aged 60 years or older with displaced (more than 1 cm or 45 degrees) 2-part surgical or anatomical neck proximal humerus fracture were randomly assigned in a 1:1 ratio to undergo either operative treatment with a locking plate or non-operative treatment. The mean age of patients was 72 years in the non-operative group and 73 years in the operative group, with a female sex distribution of 95% and 87%, respectively. Patients were recruited between February 2011 and April 2016. The primary outcome measure was Disabilities of Arm, Shoulder, and Hand (DASH) score at 2-year follow-up. Secondary outcomes included Constant-Murley score, the visual analogue scale for pain, the quality of life questionnaire 15D, EuroQol Group's 5-dimension self-reported questionnaire EQ-5D, the Oxford Shoulder Score, and complications. The mean DASH score (0 best, 100 worst) at 2 years was 18.5 points for the operative treatment group and 17.4 points for the non-operative group (mean difference 1.1 [95% CI -7.8 to 9.4], p = 0.81). At 2 years, there were no statistically or clinically significant between-group differences in any of the outcome measures. All 3 complications resulting in secondary surgery occurred in the operative group. The lack of blinding in patient-reported outcome assessment is a limitation of the study. Our assessor physiotherapists were, however, blinded.

CONCLUSIONS

This trial found no significant difference in clinical outcomes at 2 years between surgery and non-operative treatment in patients 60 years of age or older with displaced 2-part fractures of the proximal humerus. These results suggest that the current practice of performing surgery on the majority of displaced proximal 2-part fractures of the humerus in older adults may not be beneficial.

Combined navigated drilling and arthroscopy facilitate minimally invasive surgical treatment of ulnar-radial joint dislocation caused by epiphyseal premature closure: A case report

RATIONALE

In this paper, the efficacy and safety of using navigated drilling and arthroscopy (NDA) to assist surgery for ulnar-radial joint dislocation caused by epiphyseal premature closure (EPC) are described. Deformity correction surgery was mentioned in the literature, but there were numerous complications, for example, poor correction, infection, neurovascular injury, osteofascial compartment syndrome, failure of internal fixation, and nonunion after osteotomy. In order to minimize surgical complications, we utilized navigated drilling to finish accuracy bone bridge resection and applied arthroscopy to assess wrist lesions.

PATIENT CONCERNS

An 11-year-old male patient showed swelling and pain of the left wrist.

DIAGNOSES

The patient was diagnosed with a postoperative of Kirschner wire internal fixation for epiphyseal injury, left lower ulnar-radial joint dislocation, left wrist deformity, and EPC.

INTERVENTIONS

A NDA was used to assist the bone bridge resection in this patient.

OUTCOMES

Pain was relieved clearly in the patient. Dorsiflexion increased from 60.8° to 85.3°, palmar flexion increased from 45.3° to 65.8°, supination increased from 41.3° to 69.5°, and pronation increased from 31.6° to 62.9°. The preoperative disabilities of the arm, shoulder, and hand (DASH) score was 86.1, which was increased to 16.4 postoperatively. Surgery designing lasted for 2 minutes, bone bridge resection lasted for 56 minutes, and fluoroscopic time was 2.4 minutes. Complications, for example, neurological injury, vascular injury, infection and deformity aggressive, were not found during the 5-month follow up.

LESSONS

The outcome of the present study suggests that the NDA maximizes the bone bridge resection accuracy in EPC treatment, which is made efficient by reducing surgical trauma and avoiding neurovascular injury. An experience was gained that in the process of bone bridge removal, the bit of navigated drill should be continuously washed with normal saline to cool down, so as to avoid damage of nerve caused by heat conduction.
