Specific approach to total hip arthroplasty in patients with childhood hip disorders sequelae

Hip arthroplasty in patients with a history of paediatric hip disorders presents a significant challenge for orthopaedic surgeons. These patients are typically younger and have greater functional demands. Therefore, achieving optimal biomechanical conditions is crucial, involving placement of the acetabulum at the ideal centre of rotation and securing a stable femoral component with good offset to preserve abductor muscle function and restore leg length. The altered anatomy in these cases makes total hip arthroplasty more complex, necessitating thorough preoperative imaging and an individualised surgical approach. Various techniques may be employed to optimise biomechanical outcomes. We propose a modified lateral hip approach, offering exceptional visualisation of the acetabulum and femur while preserving the continuity of the abductor muscles without requiring trochanteric osteotomy. To achieve the most biomechanically advantageous acetabular position, cotyloplasty is our preferred method.

The Radiologic Evaluation and Clinical Significance of Glenohumeral Bone Loss in Anterior Shoulder Instability

Glenoid and humeral bone loss is associated with a high incidence of recurrent shoulder instability and failure of arthroscopic stabilization procedures. However, the radiographic evaluation of bony Bankart and Hill-Sachs injuries continues to pose a diagnostic challenge, and a universally accepted optimal method of measurement is lacking. The purpose of this review is to summarize the advantages and disadvantages of various techniques and imaging modalities available for measuring glenoid bone loss in shoulder instability, including conventional roentgenography, 2-dimensional and 3-dimensional computed tomography (CT), and magnetic resonance imaging (MRI). We also review the concepts of engaging "on-track" and "off-track" Hill-Sachs lesions. Finally, we highlight the clinical importance of obtaining accurate determinations of bone loss by the various methods available, as it can affect surgical decision making and the appropriate procedure required to ensure shoulder stability is adequately restored.

Which Factors Are Associated With Rerupture After Superior Capsular Reconstruction of the Shoulder With Autologous Long Biceps Tendon? - A Systematic Review

Based on a systematic review, the present work analyses factors associated with the rerupture rate or non-healing after superior capsular reconstruction with autologous long biceps tendon in the reconstruction of the rotator cuff of the shoulder.A systematic review of the U.S. National Library of Medicine/National Institutes of Health (PubMed) database and the Cochrane Library was conducted in September 2021 using the PRISMA checklist. Articles were identified and analysed that contained data on the rerupture rate after superior capsular reconstruction with autologous long biceps tendon in reconstruction of the rotator cuff of the shoulder. The aim was to identify factors associated with rerupture or non-healing. The risk of bias was determined using the Newcastle-Ottawa scale.Primarily 86 hits could be generated. Seven articles from 2020 and 2021 met the inclusion criteria and were further analysed in terms of content. The evidence level was III to IV. Follow-up was between 12 (minimum) and 24 to 48 months. The risk of bias was not low. Factors that may be associated with rerupture or non-healing are diabetes mellitus and high-grade fatty degeneration of the subscapularis, infraspinatus, or teres minor as preoperative factors. Age, percent footprint coverage, tear size, symptom duration, number of bundles, acromioplasty performed, and tear configuration were not significant factors. Gender, degree of fatty degeneration of the supraspinatus and lesions of the subscapularis tendon were rated differently.According to the literature, but still currently with short-term observation periods, superior capsular reconstruction with an autologous long biceps tendon is another treatment option in the case of massive tears and elderly patients, if there is no high-grade fatty degeneration of the subscapularis, infraspinatus or teres minor. Diabetes mellitus has an unfavorable prognosis. Additional acromioplasty has so far not been associated with better outcomes.

Subscapularis Muscle Radiographic Integrity and Patient-Reported Outcomes Following Arthroscopic Anatomic Glenoid Reconstruction With Distal Tibial Allograft

BACKGROUND

Shoulder stabilization surgery has evolved over time, and bony augmentation procedures on the glenoid side are being performed more often. The Latarjet procedure modifies subscapularis anatomy because the conjoined tendon divides the subscapularis muscle fibers through a split/takedown, which has structural and functional implications. Arthroscopic anatomic glenoid reconstruction (AAGR) re-creates anatomy. This technique uses the Halifax portal to deploy and fix a distal tibial allograft (DTA) through the rotator interval, thus preserving the subscapularis anatomy.

PURPOSE/HYPOTHESIS

The purpose was to analyze the radiographic properties of the subscapularis muscle after AAGR. It was hypothesized that the subscapularis muscle structure remains preserved postoperatively.

STUDY DESIGN

Case series; Level of evidence, 4.

METHODS

A retrospective review was performed comprising a consecutive series of patients treated with AAGR with DTA between November 2012 and April 2021 for traumatic anterior shoulder instability with glenoid bone loss. Patients were excluded if they had posterior instability, glenoid fracture, missing pre- or postoperative computed tomography (CT) scans, or only CT arthrogram available. Radiographic variables measured on CT scans included estimates of subscapularis muscle volume, subscapularis/infraspinatus muscle ratio, and fatty infiltration according to the Goutallier classification. Pre- and postoperative Western Ontario Shoulder Instability index scores were collected as a secondary outcome of this study.

RESULTS

Ninety-three patients were included in the study with a clinical follow-up of 2.3 ± 1.5 years (mean ± SD). The subscapularis volume increased from 185.91 ± 45.85 mL preoperatively to 194.1 ± 49.0 mL postoperatively (P = .006). The subscapularis to infraspinatus muscle ratio showed a significant increase from 0.96 ± 0.27 to 1.05 ± 0.30 after surgery (P = .002). All patients had a Goutallier stage of 0 before and after surgery. The Western Ontario Shoulder Instability scores showed a significant improvement from 64.8 ± 15.5 preoperatively to 28.2 ± 24.0 postoperatively (P < .001).

CONCLUSION

Patients who undergo AAGR with DTA for traumatic shoulder instability with glenoid bone loss have a preserved subscapularis muscle volume with no fatty infiltration, while showing a significant improvement in clinical outcomes.

VTE rates and risk factors in major trauma patients

BACKGROUND

Venous thromboembolism (VTE) is a common and in some instances life-threatening complication following severe traumatic injury. Owing to a lack of high-quality evidence in VTE risk prediction and prevention in this cohort, major trauma patients receive variable VTE preventative care. The aim of this systematic review was to determine the reported rates of VTE in major trauma patients, and associated risk factors.

METHODS

A comprehensive database search was conducted using EBSCO/MEDLINE, EMBASE, CINAHL, Cochrane and Scopus to identify studies published between 1990 and 2023. Original Studies quantifying the occurrence of and/or evaluating risk factors for VTE, PE and DVT in a defined population were eligible for inclusion. Five reviewers screened, appraised, and extracted data from the selected studies.

RESULTS

A total of 22 studies fulfilled the inclusion criteria. Most studies were conducted in Northern America (72 %), followed by Asia (18 %), and Europe (9 %). Of the 22 studies, 17 were retrospective, 4 were prospective and 1 was the control arm of an RCT. The reported rates in included studies ranged from 0.39 % to 32 % (VTE), 0.59 % to 57.60 % (DVT) and 0.35 % to 24.0 % (PE). Operative procedure was the most consistently reported associated variable for DVT followed by delays to prophylaxis and pelvic injury. Lower extremity injury was the most frequently reported associated variable for PE followed by male sex and increased age. Age was the most frequently reported variable for both DVT and PE.

CONCLUSION

There exists significant variation in the reported rates of VTE in major trauma patients globally. Operative procedure, delays to prophylaxis and pelvic injury were the most consistently reported associated variables for DVT. Lower extremity injury followed by male sex and increased age were the most frequently reported associated variables for PE. Although studies indicate possible differences in risk factors for DVT and PE, heterogeneity in study characteristics and outcome reporting impedes any meaningful conclusions. Reconciliation of VTE rates in major trauma patients is necessary when comparing populations.

High Vertical and Horizontal Stability at Short-Term Follow-Up After an All-Endoscopic Double Cerclage Endobutton Technique for Acute Acromioclavicular Joint Separations

PURPOSE

To evaluate the clinical and radiological outcomes in the treatment of acute acromioclavicular (AC) joint separations using an all-endoscopic double cerclage endobutton technique compared with an arthroscopic-assisted single-bundle endobutton technique and to analyze the complication, failure, and revision rates of both procedures.

METHODS

All patients with acute Rockwood type IIIB and V AC joint separations who were operated on using an all-endoscopic double cerclage technique (2019-2022) or an arthroscopic-assisted single-bundle technique (2017-2019) were included. The follow-up period was at least 12 months. Clinical and radiographic assessment was performed at follow-up. Complications, failures, and revisions were also investigated.

RESULTS

Twenty-eight patients (14 double cerclage group, 14 single-bundle group, all male) with an average age of 37 years (interquartile range [IQR], 15) were available for follow-up after 45 months (IQR, 38). The median time between trauma and surgery was 7 days (IQR, 8). Very good clinical results without significant differences were observed in both groups (Constant score, 94 [IQR, 12] vs 95 [IQR, 15], P = .427, AC joint instability score, 95 [IQR, 11] vs 87 [IQR, 22], P = .210). All patients returned to sport, with an average sports level of 95% compared with preoperative status. The single-bundle group showed significantly increased anteroposterior instability (6 vs 0, P = .006). A total of 5 complications occurred (2 vs 3), leading to 1 revision surgery in each group.

CONCLUSIONS

Excellent clinical results and high vertical and horizontal stability can be achieved with the all-endoscopic double cerclage technique. Horizontal instability occurred significantly more frequently with the single-bundle technique. The prolonged operation time in the double cerclage group had no negative impact on postoperative outcomes, including complication and failure rates, and a learning curve to reduce this prolonged operative time should be considered.

LEVEL OF EVIDENCE

Level III, retrospective comparative clinical series.

Feasibility of continuous physical activity monitoring: first-month recovery markers following joint replacement surgery

Background

The role of physical activity (PA) monitoring during the recovery after orthopaedic surgeries is unclear. This study aimed to explore early changes in the pattern and level of PA following orthopedic surgeries.

Methods

This observational feasibility study included 11 hip replacement patients (four females) with a mean age of 66 years and five knee replacement patients (four females) with a mean age of 65 years. A PA tracker was used to collect the patients' daily PA data, including duration of various activity categories, steps taken, and activity intensity count. The PA tracker recorded data from two weeks prior to surgery until four weeks after the surgery. Ratios of PA parameters for each of the first four weeks following surgery were calculated in relation to preoperative measurements.

Results

Compared to preoperative measurements, during the first four weeks after the surgery, the time spent in a recumbent position decreased from 112% to 106%, while continuous walking time and activity intensity count increased from 27% to 77% and from 35% to 73%, respectively. Step counts increased from 18% to 67%, and sit-to-stands rose from 65% to 93%. No significant changes were found in sitting, standing, sporadic walk time, and sporadic steps.

Conclusion

Continuously measuring PA using wearable sensors was feasible in orthopedic patients during the perioperative period. Continuous step count, walking time, activity intensity count showed noticeable changes and stable patterns demonstrating their potential for remote monitoring of patients during the early postoperative period.

[Postoperative rehabilitation after knee arthroplasty]

BACKGROUND

Postoperative rehabilitation after knee arthroplasty plays a decisive role in restoring the function and mobility of the affected joint. However, there is still disagreement regarding the setting, structure and content of rehabilitation after knee arthroplasty, and the evidence on the individual measures is largely unclear. The aim of this article is to provide an evidence-based overview of the current status of rehabilitation after knee arthroplasty and to critically discuss the points that are still unclear. In view of the increasing prevalence of knee osteoarthritis and the rising number of knee endoprosthesis implantations, the optimization and scientific processing of postoperative rehabilitation is more important than ever in order to be able to offer scientifically sound, practice-oriented and cost-effective rehabilitation measures in the future.

MATERIAL AND METHODS

This review is based on a systematic literature search in Medline, Cochrane Library and Web of Science databases on the topic of postoperative rehabilitation after knee arthroplasty.

RESULTS

Regarding specific treatment components, duration and frequency after knee arthroplasty, the evidence is unclear. Passive therapies should only be used supportive to active interventions. Educational programmes before and after knee arthroplasty can play a crucial role in outcome and patient satisfaction. Regular strength training should always be combined with centrally oriented components, such as motor imagery, to achieve better movement visualization and central anchoring. There is still a frequent lack of scientific evidence regarding individual therapeutic measures, their intensity, frequency, duration, exercise selection and their specific implementation in rehabilitation after knee arthroplasty. In the future, digital diagnostic and training tools will become established in both inpatient and outpatient therapy, supporting the urgently needed data collection for the scientific analysis of individual therapeutic measures.

Comparison of Clinical Outcomes Between Nonoperative Treatment and Arthroscopically Assisted Stabilization in Patients With Acute Rockwood Type 5 Acromioclavicular Dislocation

Background

Currently, Rockwood type 3 acromioclavicular (AC) joint dislocations are initially treated nonoperatively, whereas surgery is recommended for Rockwood type 5 dislocations. However, multiple studies have been published favoring nonoperative approaches in patients with high-grade Rockwood injuries.

Purpose

To compare the clinical and radiological outcomes of patients with acute Rockwood type 5 AC joint dislocations treated nonoperatively versus with arthroscopically assisted stabilization.

Study Design

Cohort study; Level of evidence, 3.

Methods

Included were 48 patients with acute Rockwood type 5 dislocation who were initially treated nonoperatively between June 2010 and June 2022 and 48 patients matched according to age, sex, affected side, and follow-up interval who underwent arthroscopically assisted coracoclavicular (CC) stabilization using a suture-button technique, with additional percutaneous AC tape cerclage. Clinical outcomes were assessed based on the Subjective Shoulder Value, Nottingham Clavicle Score, Constant score, and visual analog scale for pain. The radiographic assessment included the CC distance, CC difference ratio, and degree of horizontal instability at final follow-up (62 ± 43 months).

Results

At the final follow-up, the Constant score was significantly higher in the nonoperative group (P = .02). The operative group had significantly higher pain levels on palpation of the AC joint (1.2 ± 2.2 vs 0.19 ± 0.5 for the nonoperative group; P = .003). In the operative group, the mean CC difference ratio was significantly higher at the latest follow-up compared with postoperatively (1.3 ± 0.3 vs 0.67 ± 0.3, respectively; P < .001), whereas the CC difference ratio of the nonoperative group was significantly reduced at the latest follow-up compared with postinjury (2.0 ± 0.5 vs 2.6 ± 0.8, respectively; P < .001). The operative group had a significantly lower CC difference ratio compared with the nonoperative group at final follow-up (P < .001). More than half of the patients (56%) who were treated operatively had a loss of reduction resulting in a Rockwood type 3 state at the latest follow-up, whereas 54% of patients treated nonoperatively had spontaneous reduction of injury severity from Rockwood type 5 to Rockwood type 3.

Conclusion

Although 15% of the nonoperatively treated patients eventually required surgery, successful nonoperative treatment showed similar outcomes to initial operative treatment in patients with acute Rockwood type 5 dislocation.

[The potential of wearable technology in knee arthroplasty]

BACKGROUND

Wearable technology has developed rapidly in recent years and offers promising possibilities for supporting and optimizing orthopaedic procedures, especially pre- and postoperatively. The continuous monitoring and precise analysis of movement patterns, as well as the individual adaptation of rehabilitation processes are just some of the potential benefits of wearable technology. The aim of this paper is to evaluate the potential of wearable technology in knee arthroplasty and to provide an overview of the evidence that is currently available.

MATERIAL AND METHODS

This overview is based on a literature search in Medline, Cochrane Library and Web of Science databases on the topic of wearables and knee arthroplasty.

RESULTS

Wearable technology enables precise and, above all, long-term and objective monitoring of knee joint movements and loads-regardless of the setting and environment in which the patient is located. So-called IMUs (inertial measurement units), which can record multidimensional directions of movement and speed, are most commonly used for movement analysis. Due to their small size and manageable costs, IMUs are suitable for movement monitoring in orthopaedics. In addition, continuous data acquisition through the corresponding development of algorithms allows early detection of complications and almost real-time adjustment of therapy. As wearables can also be used in the home setting, a combination with other telemedical and/or feedback applications is possible in the course of increasing ambulantization. Wearable technology has the potential to significantly improve pre- and post-operative care and rehabilitation in knee arthroplasty. Through the precise monitoring of movement patterns and the individual adjustment options, better or equivalent results could be achieved in the future compared to current standards. Despite the promising results so far, the current evidence is still limited and further clinical studies are needed to comprehensively assess the long-term effectiveness and cost-effectiveness of knee arthroplasty.

Arthroscopic-Assisted Lateral Ulnar Collateral Ligament Reconstruction for Posterolateral Rotatory Instability of the Elbow: A Technical Note

The lateral collateral ligament complex of the elbow is pivotal for maintaining the stability of the elbow joint. The open technique for reconstructing the lateral ulnar collateral ligament (LUCL) is a standard procedure to treat elbow instability caused by LUCL deficiency. Nevertheless, as arthroscopy procedures in the elbow have advanced, we describe an arthroscopic technique to reconstruct the LUCL with suture anchors and bone tunnel techniques.

Venous Thromboembolism in Outpatient Elective Foot and Ankle Procedure Patients Who Is at Risk?

BACKGROUND

Venous thromboembolism (VTE) is a rare but potentially serious complication following elective foot and ankle (F&A) procedures. The absence of guidelines for thromboprophylaxis in elective procedures underscores the importance of identifying patients at risk. This study aimed to identify key risk factors of VTE in patients who underwent elective foot and ankle (F&A) operations.

METHODS

Data was collected from the IBM MarketScan Database (2009-2019) for patients >18 years old without prior VTE who underwent elective F&A procedures. Patients were divided into 3 groups based on region of operation (forefoot, mid/hindfoot, lower leg/ankle). VTE incidence (including deep vein thrombosis and/or pulmonary embolism) was recorded 30 and 90 days postprocedure. Risk factors for VTE were identified through multivariate logistic regression.

RESULTS

Among the 301 256 patients who underwent elective F&A procedures, the overall 90-day incidence of VTE was 0.95%. The findings revealed that 31.9% of VTE incidents occurred within the first 2 weeks after operation, and 29.2% still occurred after 6 weeks. Analysis of the anatomical region of operation demonstrated that the lowest rate of 90-day VTE was amongst patients undergoing forefoot procedures (0.70%). There was a higher risk for VTE in patients undergoing midfoot/hindfoot procedures (1.22%, OR = 1.81) and lower leg/ankle procedures (1.76%, OR = 2.31). Additional risk factors for VTE included thrombophilia (4.02%, OR = 3.37), male sex (1.30%, OR = 1.47), increasing age (1.02% age 65+, OR = 1.41), and a high Charlson Comorbidity Index (1.12%, OR < 0.82 for scores <5).

CONCLUSION

This study identifies the incidence and timing for VTE after elective F&A procedures. Furthermore, this study defines the risk factors associated with increased odds of VTE after elective F&A procedures. These findings are helpful in educating patients about a continued risk for VTE throughout the 90-day postoperative period and beyond. These results can also be utilized to stratify patients who need thromboprophylaxis based on the individual risk level.

Long-term results of total hip arthroplasty in severe congenital hip disease: A ten- to 20-year follow-up study

INTRODUCTION

The impact of bone deformities, previous surgeries, and the surgical technique in total hip arthroplasty (THA) for congenital dislocation of the hip (CDH) at a long-term has not been clearly defined yet. In this single-centre observational study we sought to assess patients undergoing THA due to osteoarthritis secondary to severe CDH with low or high dislocation ten- to 20-years after surgery. To determine this purpose, we assessed: (1) THA-related complications and reoperations; (2) the clinical outcome, patients' satisfaction and radiological results; and (3) the possible risk factors for reoperation with particular attention to the surgical technique and the influence of prior surgeries.

HYPOTHESIS

We hypothesized that an anatomical reconstruction of the hip would decrease the reoperations rates in patients undergoing THA with severe CDH.

METHODS

Seventy-five patients (85 hips) operated between 1999 and 2012 at our large tertiary hospital were analyzed. Fifty-six hips were diagnosed as low dislocation (group 1) and 29 hips as high dislocation (group 2). The existence of prior surgeries was frequent: group 1, pelvic osteotomies 6 hips, femoral osteotomies 7, tectoplasty (shelf) 6, resection arthroplasty 1 and lowering of the greater trochanter 1; group 2 included pelvic osteotomies 10 hips, femoral osteotomies 10, and a femoral lengthening 2. The number of additional procedures during THA was: group 1 (19/56 [34%]), acetabular roof bone autograft 8 hips, acetabular medial wall autograft 2, hardware removal 6, extended femoral osteotomy 2, and a femoral shortening 1; group 2 (20/29 [69%]), acetabular bone autograft 12 hips, medial autograft 1, hardware removal 1, extended femoral osteotomy 2, and a femoral shortening 4 hips. The clinical and the radiological analysis were compared in both groups for a minimum follow-up of ten years. Cox regression models were used to detect risk factors for reoperation.

RESULTS

Nine patients (13.8%) required reoperation for the following reasons: cup loosening (5 hips), periprosthetic femoral fracture (3) and stem loosening (1); seven had prior surgeries. The 12-year survival rate for reoperation for any reason was 96.3% (95% confidence interval [CI] 91.2-100) in group 1 and 75.7% (95% CI, 65.8-90.8) in group 2 (p=0.003). Patients with high dislocation (p=0.02, hazard ratio [HR]: 6.25, 95% CI, 1.26-30.9) and those with an acetabular component inclination placed out of the target zone between 35° and 50° (p=0.03, HR: 4.27, 95% CI, 1.13-16.1) had a higher risk of reoperation.

DISCUSSION

An optimal placement of the acetabular component decreased the reoperation rates in patients undergoing THA for severe CDH. Hips with high dislocation and the existence of prior surgery can affect THA implantation.

A Comparative Study on Arthroscopic Superior Capsular Reconstruction Using Fascia Lata Autograft With and Without Long Head of the Biceps Tendon Augmentation: Two-Year Patient-Reported Outcomes and Radiographic Analysis

BACKGROUND

Given the growing concerns regarding objective measures of clinical outcomes, attention has recently been devoted to the establishment of clinically significant outcome (CSO) thresholds for patient-reported functional scores after rotator cuff surgery.

PURPOSE

To retrospectively compare patient-reported outcome (PRO) measures (PROMs) and radiographic data between patients who underwent arthroscopic superior capsular reconstruction (SCR) with and without long head of the biceps tendon (LHBT) augmentation.

STUDY DESIGN

Cohort study; Level of evidence, 3.

METHODS

A total of 43 patients receiving arthroscopic SCR between 2016 and 2020 were enrolled, including a biceps augmentation group (n = 27) and a nonaugmentation group (n = 16). Patients were asked an anchor question regarding their satisfaction and perception of improvements. PROMs of American Shoulder and Elbow Surgeons (ASES), Constant score, Single Assessment Numeric Evaluation (SANE), and visual analog scale (VAS) for pain scores and radiographic data including magnetic resonance imaging and plain radiographs were collected and compared between the 2 groups. Anchor questions in CSO analysis for deriving the minimal clinically importance difference (MCID), substantial clinical benefit (SCB), Patient Acceptable Symptom State (PASS), and maximal outcome improvement (MOI) values were applied ≥2 years postoperatively.

RESULTS

Based on satisfaction responses, 17 patients were classified as satisfied, 16 as unsatisfied, and 10 as fair. Additionally, 13 patients felt they were improved, 14 changed, and 16 unchanged. Intergroup comparison based on patients' satisfaction and perception of change or improvement exhibited significant differences in all 4 functional scores in favor of the satisfied and improved patients. However, there was no significant difference in the ΔVAS scores between the groups. CSO analyses showed no significant difference in percentage of patients achieving MCID, SCB, and PASS thresholds for the ΔASES, ΔConstant, and ΔSANE scores between patients undergoing arthroscopic SCR with or without LHBT augmentation. A significant difference was found in the percentage of patients achieving the MOI for ΔASES score with 70.4% in the augmented group and 37.5% in the nonaugmented group, respectively. The mean acromiohumeral distance (AHD) differed significantly between augmentation (8.1 ± 2.2 mm) and nonaugmentation (7 ± 1.9 mm) groups. The graft tear rate did not differ significantly.

CONCLUSION

There was no significant difference in PROs and percentage of patients achieving MCID, SCB, and PASS between isolated and augmented SCR groups. A higher percentage of patients achieving MOI and slightly greater AHD were found in the augmented group. Further evaluation is required to determine if there is any long-term benefit to LHBT augmentation of SCR.

Management of bone loss in anterior shoulder instability

Bone defects are frequently observed in anterior shoulder instability. Over the last decade, knowledge of the association of bone loss with increased failure rates of soft-tissue repair has shifted the surgical management of chronic shoulder instability. On the glenoid side, there is no controversy about the critical glenoid bone loss being 20%. However, poor outcomes have been described even with a subcritical glenoid bone defect as low as 13.5%. On the humeral side, the Hill-Sachs lesion should be evaluated concomitantly with the glenoid defect as the two sides of the same bipolar lesion which interact in the instability process, as described by the glenoid track concept. We advocate adding remplissage to every Bankart repair in patients with a Hill-Sachs lesion, regardless of the glenoid bone loss. When critical or subcritical glenoid bone loss occurs in active patients (> 15%) or bipolar off-track lesions, we should consider anterior glenoid bone reconstructions. The techniques have evolved significantly over the last two decades, moving from open procedures to arthroscopic, and from screw fixation to metal-free fixation. The new arthroscopic techniques of glenoid bone reconstruction procedures allow precise positioning of the graft, identification, and treatment of concomitant injuries with low morbidity and faster recovery. Given the problems associated with bone resorption and metal hardware protrusion, the new metal-free techniques for Latarjet or free bone block procedures seem a good solution to avoid these complications, although no long-term data are yet available.

The Latarjet Procedure for Recurrent Anterior Shoulder Instability in the Contact Athlete

In young athletes, anterior shoulder instability is a prevalent condition. Because of high-energy traumas, contact athletes often suffer recurrent instability, bone loss and postoperative recurrences. Patients younger than 20 years, symptomatic for more than 6 months, with ≥ 2 dislocations, with off-track Hill-Sachs lesion, glenoid bone loss, ALPSA lesion, Instability Severity Index Score > 3, and Glenoid Track Instability Management Score > 3 are at higher risk of failure. In cases of multiple dislocations with critical or subcritical glenoid bone loss, notably in collision and contact athletes, the Latarjet procedure is widely recognized as the treatment of choice.

Outcomes of arthroscopic stabilization for recurrent instability are equal to stabilization after a primary event

Aims

Extensive literature exists relating to the management of shoulder instability, with a more recent focus on glenoid and humeral bone loss. However, the optimal timing for surgery following a dislocation remains unclear. There is concern that recurrent dislocations may worsen subsequent surgical outcomes, with some advocating stabilization after the first dislocation. The aim of this study was to determine if the recurrence of instability following arthroscopic stabilization in patients without significant glenoid bone loss was influenced by the number of dislocations prior to surgery.

Methods

A systematic review and meta-analysis was performed using the PubMed, EMBASE, Orthosearch, and Cochrane databases with the following search terms: ((shoulder or glenohumeral) and (dislocation or subluxation) and arthroscopic and (Bankart or stabilisation or stabilization) and (redislocation or re-dislocation or recurrence or instability)). Methodology followed the PRISMA guidelines. Data and outcomes were synthesized by two independent reviewers, and papers were assessed for bias and quality.

Results

Overall, 35 studies including 7,995 shoulders were eligible for analysis, with a mean follow-up of 32.7 months (12 to 159.5). The rate of post-stabilization instability was 9.8% in first-time dislocators, 9.1% in recurrent dislocators, and 8.5% in a mixed cohort. A descriptive analysis investigated the influence of recurrent instability or age in the risk of instability post-stabilization, with an association seen with increasing age and a reduced risk of recurrence post-stabilization.

Conclusion

Using modern arthroscopic techniques, patients sustaining an anterior shoulder dislocation without glenoid bone loss can expect a low risk of recurrence postoperatively, and no significant difference was found between first-time and recurrent dislocators. Furthermore, high-risk cohorts can expect a low, albeit slightly higher, rate of redislocation. With the findings of this study, patients and clinicians can be more informed as to the likely outcomes of arthroscopic stabilization within this patient subset.

Venous Thromboembolism Prevention in Rehabilitation: A Review and Practice Suggestions

ABSTRACT

Venous thromboembolism is a frequent complication of acute hospital care, and this extends to inpatient rehabilitation. The timely use of appropriate thromboprophylaxis in patients who are at risk is a strong, evidence-based patient safety priority that has reduced clinically important venous thromboembolism, associated mortality and costs of care. While there has been extensive research on optimal approaches to venous thromboembolism prophylaxis in acute care, there is a paucity of high-quality evidence specific to patients in the rehabilitation setting, and there are no clinical practice guidelines that make recommendations for (or against) thromboprophylaxis across the broad spectrum of rehabilitation patients. Herein, we provide an evidence-informed review of the topic with practice suggestions. We conducted a series of literature searches to assess the risks of venous thromboembolism and its prevention related to inpatient rehabilitation as well as in major rehabilitation subgroups. Mobilization alone does not eliminate the risk of venous thromboembolism after another thrombotic insult. Low molecular weight heparins and direct oral anticoagulants are the principal current modalities of thromboprophylaxis. Based on the literature, we make suggestions for venous thromboembolism prevention and include an approach for consideration by rehabilitation units that can be aligned with local practice.

3D C-arm navigated suture button implantation for AC joint dislocations - the pilot study

PURPOSE

The surgical treatment of acute traumatic AC joint dislocations is still a subject of scientific debate in the literature. The arthroscopically assisted stabilization procedure with a suture button system has been successfully established and is widely used in daily practice. It is minimally invasive and allows the anatomical reconstruction of the torn coracoclavicular ligaments in one step with a permanent implant that does not have to be removed in a second operation. This clinical pilot study is the first to describe the new method of navigated suture button implantation with the future aim of further reducing surgical invasiveness and further increasing surgical precision.

MATERIALS AND METHODS

10 patients with a Rockwood 3b/5 injury could be included in the prospective study (DRKS00031855) within 5 months according to inclusion and exclusion criteria. Surgical stabilization was performed with a suture button system via a navigated coracoclavicular drill tunnel. Demographic and radiological data as well as information on health and shoulder function were collected from patient records, X-rays, DVT scan and 3 questionnaires (DASH, NHS and Eq. 5D) at the preoperative, intraoperative and postoperative (discharge, 6 weeks and 3 months) time points.

RESULTS

All operations could be performed within 8.8 days (± 6.81) after trauma. The average operation time was 50.3 min (± 8.81). The mean distance of the drill hole in the clavicle to the AC joint was 26.6 mm (± 2.63). The radiologically measured vertical coracoclavicular distance was 38.8 mm (± 6.16) at discharge and 41.11 mm (± 7.51) at 3 months. This loss of reduction was not statistically significant. In contrast, the DASH, NHS and Eq. 5D results showed significant improvement from discharge to 3 months postoperatively.

CONCLUSION

Image-guided 3D C-arm navigated AC joint suture button stabilization is feasible in everyday surgical practice. It may be possible to achieve a further reduction in invasiveness while at the same time increasing the accuracy of implant positioning. Further clinical studies with a larger number of patients and a longer follow-up period are necessary to enable a comparison with conventional methods.

Enoxaparin and Early Postoperative Tibial Nailing: Increased Nonunion Revision Rates

OBJECTIVES

To determine the association between postoperative enoxaparin use and the risk of requiring surgery for nonunion in patients treated with intramedullary nailing for midshaft fractures of the tibia.

METHODS

DESIGN

Retrospective cohort analysis.

SETTING

Data were sourced from the PearlDiver national database.

PATIENT SELECTION CRITERIA

Patients were identified through the PearlDiver database by using Current Procedural Terminology and International Classification of Diseases (ICD-10) codes. Included patients had undergone intramedullary nailing for midshaft fractures of the tibia between 2015 and 2020 and subsequently underwent revision surgery due to nonunion.

OUTCOME MEASURES AND COMPARISONS

The primary outcome measured in this study was the rate of nonunion following intramedullary nailing for the different types of tibial shaft fractures (closed, Type I/II open, Type III open). For each fracture subtype, the study compared nonunion rates between those who received enoxaparin in the postoperative period and those who did not receive enoxaparin at any time during the first 6 weeks postoperatively. Factors such as the timing and duration of enoxaparin therapy and demographic variables were also considered.

RESULTS

The study included 16,986 patients, average age was 49.2 years (SD 17.3); 43.1% were female. Five hundred four patients required revision surgery for nonunion (3.4%). Among patients who did not receive enoxaparin, the nonunion rates were 1.6%, 3.9%, and 6.9% for closed, Type I/II open, and Type III open fractures, respectively. For patients who received enoxaparin within the first 2 weeks, the nonunion rates were 2.6%, 4.7%, and 7.9% for closed (RR = 1.67, P < 0.0001), Type I/II open (RR = 1.21, P < 0.0001), and Type III open (RR = 1.17, P = 0.355) fractures, respectively. Logistic regression confirmed enoxaparin was independently associated with nonunion (odds ratios [OR] = 1.75, P = 0.0013 for closed fractures; OR = 1.51, P = 0.034 for Type I/II open fractures). Tobacco use was also a contributing factor (OR = 2.43, P < 0.0001 for closed fractures; OR = 2.00, P < 0.0001 for Type I/II open fractures; OR = 2.04, P = 0.0008 for Type III open fractures).

CONCLUSIONS

The postoperative use of enoxaparin was associated with an elevated risk of nonunion in patients treated with intramedullary nailing for fractures of the tibial shaft.

Sub-Acromioclavicular Decompression Increases the Risk of Postoperative Shoulder Stiffness after Arthroscopic Rotator Cuff Repair

OBJECTIVE

The sub-acromioclavicular (SAC) decompression is often performed during arthroscopic rotator cuff repair. However, the impact of SAC decompression on patients with postoperative shoulder stiffness (POSS) are controversial and unclear. This study is aim to evaluate the impact of additional sub-acromioclavicular (SAC) decompression during arthroscopic rotator cuff repair on the postoperative shoulder stiffness (POSS) in patients.

METHODS

This retrospective study examined digital data from patients with full-thickness rotator cuff tears who underwent arthroscopic rotator cuff repair at a local institution. Patient-reported outcomes were evaluated using the American Shoulder and Elbow Surgeons (ASES) Score, the University of California-Los Angeles (UCLA) score, and visual analog scale (VAS) scores. Restricted shoulder mobility occurring within 6 months postoperatively, lasting more than 12 weeks, characterized by a passive forward flexion angle of <120° or an external rotation angle of <30°, with or without associated shoulder pain was identified as POSS. Factors affecting POSS were analyzed by binary logistic regression analysis. The patient-reported outcomes scores were analyzed by generalized estimating equations to examine the impact of SAC decompression.

RESULTS

A total of 155 patients met the set criteria and were included in the study. The analysis of binary logistic regression showed that diabetes (p = 0.001) and SAC decompression (p = 0.003) were independent factors for POSS. In the analysis of each follow-up point, only at the 3-month follow-up, the ASES scores (p = 0.003), UCLA scores (p = 0.045), and VAS scores (p = 0.005) showed significant differences between the SAC decompression group and the non-decompression group. For the intergroup comparison, the results showed a significant difference in the ASES scores (β = -4.971, p = 0.008), UCLA scores (β = -1.524, p = 0.019), and VAS scores (β = 0.654, p = 0.010) throughout the study duration between the SAC decompression group and the non-decompression group.

CONCLUSION

The findings of this study suggested that SAC decompression during arthroscopic rotator cuff repair increase the risk of POSS compared with those without the decompression, which indicate surgeons do not perform SAC decompression unless necessary.

Effectiveness and safety of rivaroxaban or low-molecular-weight heparin in non-major orthopedic surgery: a meta-analysis of randomized controlled trials

BACKGROUND

Patients undergoing non-major orthopedic surgery often face an increased risk of venous thromboembolism due to the necessity of immobilization postoperatively. Current guidelines commonly recommend the use of low-molecular-weight heparin (LMWH) for prophylaxis, but it is associated with low patient compliance and certain side effects. We conducted a meta-analysis of randomized controlled trials (RCTs) to assess the effectiveness and safety of rivaroxaban or LMWH for thromboprophylaxis following non-major orthopedic surgery.

METHOD

Relevant literature was systematically searched in PubMed, Web of Science, Cochrane Library, and Embase from their inception to October 1, 2023, to evaluate the effectiveness and safety of rivaroxaban or LMWH in RCTs for thromboprophylaxis following non-major orthopedic surgery.

RESULTS

A total of 5 randomized controlled trials involving 5,101 patients were included. There was no statistically significant difference in the preventive effect against venous thromboembolism (VTE) when using rivaroxaban or LMWH following non-major orthopedic surgery (RR 0.80; 95%CI 0.31 to 2.07). In terms of safety, there was also no statistically significant difference in the incidence of bleeding events in patients undergoing non-major orthopedic surgery when using rivaroxaban or LMWH (RR 1.15; 95% CI 0.75 to 1.76).

CONCLUSION

In non-major orthopedic surgery, the risk of venous thromboembolism and bleeding complications is similar when using rivaroxaban or LMWH.

Transcriptome sequencing reveals inflammation and macrophage heterogeneity in subacromial bursa from degenerative shoulder disorders

PURPOSE

We aimed to investigate the transcriptomic alterations that occur in the subacromial bursa (SAB) following degenerative or traumatic shoulder diseases.

MATERIALS AND METHODS

RNA sequencing was employed to evaluate the transcriptomic alterations of the SAB in individuals afflicted with degenerative rotator cuff tear (RCT), traumatic RCT and proximal humerus fracture (PHF). To gain insights into the biological significance of differentially expressed genes (DEGs), we conducted an enrichment analysis utilizing Gene Ontology (GO) terms and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathways. We further utilized single-cell RNA sequencing datasets of SAB from a recently published study to explore the associated cellular dynamics and alterations.

RESULTS

We detected 1,790 up-regulated and 1,964 down-regulated DEGs between degenerative RCT and PHF, 2,085 up-regulated and 1,919 down-regulated DEGs between degenerative RCT and traumatic RCT, and 20 up-regulated and 12 down-regulated DEGs between traumatic RCT and PHF. Given the similar expression pattern between traumatic RCT and PHF, they were integrated as the traumatic group. In comparison with the traumatic group, 1,983 up-regulated and 2,205 down-regulated DEGs were detected in degenerative SAB. Enrichment analysis of up-regulated DEGs uncovered an elevated inflammatory and immunologic responses in degenerative SAB. Single-cell transcriptomic analysis revealed macrophage represented the immune cell with the most DEGs between the degenerative and traumatic RCT.

CONCLUSION

Our results revealed that the SAB in degenerative RCT exhibited a different transcriptional signature compared to that in traumatic RCT, and enrichment analysis showed immunologic and inflammatory activations. Macrophages may play a fundamental role in this process.

TASMAN Collaborative. Patterns of opioid use after surgical discharge: a multicentre, prospective cohort study in 25 countries

BACKGROUND

Excessive opioid prescribing following surgery contributes to the growing opioid crisis. Prescribing practices are modifiable, yet data to guide appropriate prescription of opioids at surgical discharge remain sparse. This study aimed to evaluate factors associated with opioid consumption following discharge from surgery.

METHODS

An international prospective multicentre cohort study was performed recruiting adult patients undergoing common general, orthopaedic, gynaecological and urological surgery, with follow-up 7 days after discharge. The primary outcome measures were the quantities of prescribed and consumed opioids in oral morphine milligram equivalents. Descriptive and multivariable analyses were performed to investigate factors associated with the primary outcome measures.

RESULTS

This analysis included 4273 patients from 144 hospitals in 25 countries. Overall, 1311 (30.7%) patients were prescribed opioids at discharge. For those patients prescribed opioids, mean (SD) 179 (240) oral morphine milligram equivalents were prescribed, yet only 81 (145) oral morphine milligram equivalents were consumed within the first 7 days after discharge. An increased dose of opioids prescribed at discharge was associated with an increased dose of opioids consumed during the follow-up period (β = 0.33 (95%CI 0.31-0.34), p < 0.001). The risk of prescribing more opioids than patients consumed increased as quantities of opioids prescribed at discharge exceeded 100 oral morphine milligram equivalents, independent of patient comorbidity, procedure and pain. Patients were prescribed more than twice the quantity of opioids they consumed in the first 7 days following discharge from surgery.

CONCLUSIONS

Our data suggest that the current quantities of opioids provided at discharge exceed patient needs and may contribute to increasing community opioid use and circulation.

Position paper on how technology for human motion analysis and relevant clinical applications have evolved over the past decades: Striking a balance between accuracy and convenience

BACKGROUND

Over the past decades, tremendous technological advances have emerged in human motion analysis (HMA).

RESEARCH QUESTION

How has technology for analysing human motion evolved over the past decades, and what clinical applications has it enabled?

METHODS

The literature on HMA has been extensively reviewed, focusing on three main approaches: Fully-Instrumented Gait Analysis (FGA), Wearable Sensor Analysis (WSA), and Deep-Learning Video Analysis (DVA), considering both technical and clinical aspects.

RESULTS

FGA techniques relying on data collected using stereophotogrammetric systems, force plates, and electromyographic sensors have been dramatically improved providing highly accurate estimates of the biomechanics of motion. WSA techniques have been developed with the advances in data collection at home and in community settings. DVA techniques have emerged through artificial intelligence, which has marked the last decade. Some authors have considered WSA and DVA techniques as alternatives to "traditional" HMA techniques. They have suggested that WSA and DVA techniques are destined to replace FGA.

SIGNIFICANCE

We argue that FGA, WSA, and DVA complement each other and hence should be accounted as "synergistic" in the context of modern HMA and its clinical applications. We point out that DVA techniques are especially attractive as screening techniques, WSA methods enable data collection in the home and community for extensive periods of time, and FGA does maintain superior accuracy and should be the preferred technique when a complete and highly accurate biomechanical data is required. Accordingly, we envision that future clinical applications of HMA would favour screening patients using DVA in the outpatient setting. If deemed clinically appropriate, then WSA would be used to collect data in the home and community to derive relevant information. If accurate kinetic data is needed, then patients should be referred to specialized centres where an FGA system is available, together with medical imaging and thorough clinical assessments.

A Retrospective Study of 1076 Cases of Shoulder Dislocation at a Single Center in Türkiye to Evaluate the Role of Post-Reduction Radiography in the Detection of Clinically Significant Fractures

BACKGROUND The role of post-reduction radiography in patients with shoulder dislocation remains controversial. Therefore, this retrospective study of 1076 cases of shoulder dislocation at a single center in Türkiye aimed to evaluate the role of post-reduction radiography in the detection of clinically significant fractures. MATERIAL AND METHODS Patients with radiographically confirmed anterior shoulder dislocation were included in the study, and their demographic data, mechanism of injury, pre- and post-reduction radiograph readings, reduction method, and patient outcome were recorded. The study analyzed patients who had pre- and post-reduction anterior-posterior and axillary shoulder radiographs. RESULTS During the 44-month study period, a total of 1076 patients were examined, and their pre- and post-reduction radiographs were reviewed by an independent radiologist. Of these patients, 27 (2.6%) had a fracture on their pre-reduction radiographs, while 32 (3.1%) had a fracture on their post-reduction radiographs. The difference between the 2 groups was not statistically significant (P=0.142). The study found that patients who did not undergo a post-reduction radiograph spent an average of 106 min in the emergency department, while patients who had the radiograph and were discharged spent an average of 237 min. The hospital stay of patients who had the radiograph was also significantly longer (P<0.01). CONCLUSIONS Our study supports that routine use of post-reduction radiographs in all cases of anterior shoulder dislocation may not be necessary and could potentially expose patients to unnecessary radiation exposure and healthcare costs. Shortening the examination time in the emergency department by not taking a follow-up radiograph will help prevent overcrowding.

Botulinum toxin type A injection combined with biofeedback in the treatment of spastic pelvic floor syndrome

BACKGROUND

Spastic pelvic floor syndrome (SPFS) is a refractory pelvic floor disease characterized by abnormal (uncoordinated) contractions of the external anal sphincter and puborectalis muscle during defecation, resulting in rectal emptation and obstructive constipation. The clinical manifestations of SPFS are mainly characterized by difficult defecation, often accompanied by a sense of anal blockage and drooping. Manual defecation is usually needed during defecation. From physical examination, it is commonly observed that the patient's anal muscle tension is high, and it is difficult or even impossible to enter with his fingers.

AIM

To investigate the characteristics of anorectal pressure and botulinum toxin A injection combined with biofeedback in treating pelvic floor muscle spasm syndrome.

METHODS

Retrospective analysis of 50 patients diagnosed with pelvic floor spasm syndrome. All patients underwent pelvic floor surface electromyography assessment, anorectal dynamics examination, botulinum toxin type A injection 100 U intramuscular injection, and two cycles of biofeedback therapy.

RESULTS

After the botulinum toxin A injection combined with two cycles of biofeedback therapy, the patient's postoperative resting and systolic blood pressure were significantly lower than before surgery (P < 0.05). Moreover, the electromyography index of the patients in the resting stage and post-resting stages was significantly lower than before surgery (P < 0.05).

CONCLUSION

Botulinum toxin A injection combined with biofeedback can significantly reduce pelvic floor muscle tension in treating pelvic floor muscle spasm syndrome. Anorectal manometry is an effective method to evaluate the efficacy of treatment objectively. However, randomized controlled trials are needed.

Comparison between arthroscopic Bankart repair versus arthroscopic Bankart/SLAP lesion repair in limited-contact athletes with type V SLAP lesion. A prospective cohort study

PURPOSE

The aim of this study was to compare the functional outcomes, recurrence rate, range of motion (ROM) and return to sports activities between arthroscopic Bankart repair (ABR) versus arthroscopic Bankart/SLAP repair (ABR/S) in limited contact-athletes with a type V SLAP lesion in the scenario of recurrent anterior shoulder instability (RASI). Our hypothesis was that there is no difference between the two treatments.

METHODS

Two groups of 45 limited-contact athletes with type V SLAP lesion were created. Group 1 underwent an arthroscopic Bankart repair, while group 2 had an arthroscopic Bankart/SLAP repair. The minimum follow-up period was 2 years. The WOSI and ASES scores were used to assess primary functional outcomes. Recurrence rate, ROM and return to sport were also evaluated.

RESULTS

Significant differences were reported in the WOSI and ASES scores pre- and post-operatively in each group. There were no significant differences between the two groups (P = 0.78 and 0.43). We reported 4 recurrences (8.8 %) in group 1 and 5 (11.1 %) in group 2, with no difference between them (P = 0.62). There were no significant differences between the range of motion of each of the groups as well as between them. More than 90% of the athletes in both groups returned to their previous sporting activities.

CONCLUSIONS

Limited-contact athletes with RASI who have a type V SLAP lesion as their primary diagnosis can be treated using either ABR or ABR/S with equal efficacy. Both treatment alternatives preserve athlete's function, stability, ROM and return to sport.

Superior capsular reconstruction with the long head of the biceps tendon achieves excellent clinical results and low rotator cuff rerupture rates one year after cuff repair surgery

PURPOSE

To analyze the clinical one-year evolution of healed and rerupture lesions in patients who received a rotator cuff repair plus Superior Capsular Reconstruction (SCR) with the long head of the biceps (LHB). Moreover, to compare this evolution between men and women.

METHODS

A pilot study was conducted on patients who underwent a rotator cuff repair plus SCR with LHB between February 2021 and June 2022. All patients completed pre-operative and one-year post-operative evaluations for tendon type of tear and tendon integrity using Magnetic Resonance Imaging (MRI)after one year of the surgery. Besides, functionality was evaluated with the American Shoulder and Elbow Surgeons (ASES) score; the visual analog scale for pain (VAS); and the Constant score.

RESULTS

A total of 38 patients completed the one-year final evaluation, they presented an increased functionality score to 83 and 86 in Constant and ASES scales (p < .001), respectively. Besides, 84% of the patients presented a healed cuff, while rerupture occurred in 16% of the patients. There were differences between the healed and rerupture patients in the total Constant score, with a remarkable increase in the strength subscale, almost double for patients with healed cuff (p < .001); in the same way, daily life activity score, and balance subscale increased, while pain score decreased in the healed cuff group (p < .05). There was no difference in functionality between men and women (p > .05). Besides, almost all patients achieved the MCID in both ASES and Constant total scores, irrespectively of the healing group.

CONCLUSION

The cuff repair using SCR with the LHB achieved a low percentage of rerupture and a functional improvement after one year of follow-up. Patients who healed the lesion presented more strength and better performance in daily life activities than those with cuff repurture. Thus, SCR + LHB procedure can be considered an efficient technique for rotator cuff repair surgery for both men and women. Although a comparison with a control group is needed to confirm these findings.

Editor's Choice - International Perspective on Extremity Vascular Trauma in Children: A Scoping Review

OBJECTIVE

Extremity vascular trauma in children can result in significant morbidity and mortality. Most published studies have focused on supracondylar humeral fracture related injuries, with little focus on other injuries. This scoping review describes the current state of knowledge on paediatric vascular injuries in the upper and lower limbs, excluding injuries related to supracondylar humeral fractures.

METHODS

MEDLINE, PubMed, Web of Science, and Cochrane databases were searched for relevant studies evaluating the epidemiology, diagnosis, management, and outcomes of upper and lower limb vascular trauma in those aged under 18 years. Studies related to supracondylar humeral fractures were excluded. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) extension for Scoping Reviews was used.

RESULTS

A total of 39 studies was included, all of which were retrospective, and 74% of which were based in North America or Europe. Extremity vascular trauma was reported to cause 0.6 - 4.4% of all paediatric trauma admissions, with penetrating mechanisms and upper limb injuries being the most common. Operative intervention was reported in 80 - 100% of children in the included studies. Primary repair was the most commonly reported operative intervention, followed by interposition graft and bypass graft. Synthetic graft use was less commonly reported (incidence range 0.5 - 33%). Lower limb fasciotomies and amputations were not commonly reported (incidence range 0 - 23% and 0 - 13%, respectively). The mortality rate appeared low, with 23 studies reporting no deaths (incidence range 0 - 4%). Complications were reported inconsistently, with no uniform outcome or follow up measures used.

CONCLUSION

The incidence of extremity vascular trauma appears low in children, with penetrating mechanisms and upper extremity injuries appearing to dominate. Most studies are from high income countries, with probable selection bias towards those treated by operative intervention. Prospective studies are required focusing on patterns of injury, rates of operative and endovascular intervention, and long term outcomes.

Postoperative Multimodal Analgesia Strategy for Enhanced Recovery After Surgery in Elderly Colorectal Cancer Patients

Enhanced Recovery After Surgery (ERAS) protocols have substantially proven their merit in diminishing recuperation durations and mitigating postoperative adverse events in geriatric populations undergoing colorectal cancer procedures. Despite this, the pivotal aspect of postoperative pain control has not garnered the commensurate attention it deserves. Typically, employing a multimodal analgesia regimen that weaves together nonsteroidal anti-inflammatory drugs, opioids, local anesthetics, and nerve blocks stands paramount in curtailing surgical complications and facilitating reduced convalescence within hospital confines. Nevertheless, this integrative pain strategy is not devoid of pitfalls; the specter of organ dysfunction looms over the geriatric cohort, rooted in the abuse of analgesics or the complex interplay of polypharmacy. Revolutionary research is delving into alternative delivery and release modalities, seeking to allay the inadvertent consequences of analgesia and thereby potentially elevating postoperative outcomes for the elderly post-colorectal cancer surgery populace. This review examines the dual aspects of multimodal analgesia regimens by comparing their established benefits with potential limitations and offers insight into the evolving strategies of drug administration and release.

Axillary Artery Injury Encountered During Chest Wall Tumor Resection

Axillary artery injuries are rare because of their anatomy but are sometimes fatal because of the difficulty of obtaining vascular integrity. We report a 50-year-old patient with an iatrogenic axillary arterial injury that occurred during the resection of a chest wall tumor. The injury occurred during an incision of the intercostal muscle along the superior margin of the second rib. Following primary hemostasis achieved by forceps and amputation of the pectoralis minor muscle, the injury site was exposed sufficiently and successfully repaired by a vascular surgeon. This successful case provided valuable insight into strategies, primary hemostasis, and subsequent revascularization for an intraoperative vascular injury.

Anterior Labrum Periosteal Sleeve Avulsion Lesions of the Shoulder: A Scoping Review

Background

Anterior labrum periosteal sleeve avulsion (ALPSA) lesion of the shoulder is defined as a labral avulsion with an intact periosteum of the glenoid neck resulting in medial malattachment of the labrum, which is both nonanatomic and nonfunctional. It is relatively rare compared with Bankart lesions, and its results are usually reported in combination with other anterior labroligamentous lesions in the literature.

Purpose

To (1) assess the size and scope of the literature on ALPSA lesions, (2) highlight the importance of this lesion, and (3) distinguish between ALPSA and Bankart lesions in diagnostic and treatment strategies.

Study Design

Scoping review; Level of evidence, 4.

Methods

The PubMed, Scopus, Embase, and Google Scholar databases were searched with the keywords "ALPSA,""anterior labrum periosteal sleeve avulsion,""anterior labral periosteal sleeve avulsion," and "anterior labroligamentous periosteal sleeve avulsion" lesion. Duplicate articles and those that did not meet the inclusion criteria were excluded, resulting in the identification of 42 relevant articles. Their references were analyzed for further data curation.

Results

This scoping review demonstrated that ALPSA lesions are difficult to clinically identify. Magnetic resonance angiography in the adduction internal rotation position is the most sensitive and specific imaging modality for identification. Optimal views are the anterosuperior portal for accurate identification and the anteroinferior portal for surgical repair during arthroscopy. Treatment begins with correctly identifying the labrum, in contradistinction to dense reactive fibrous tissue, and reattaching the labrum to the correct anatomic glenoid footprint. Chronic lesions with bone loss require either bone block or soft tissue augmentation procedures.

Conclusion

There is paucity of exclusive literature on ALPSA lesions. It is important to distinguish this lesion from the Bankart lesion as it is associated with worse outcomes. The higher failure rates of ALPSA lesion repair indicate that the current repair techniques require further refinement to improve the outcomes to the standard of Bankart lesions.

Anti-Inflammatory and Antioxidant Properties of a New Mixture of Vitamin C, Collagen Peptides, Resveratrol, and Astaxanthin in Tenocytes: Molecular Basis for Future Applications in Tendinopathies

Tendinopathy is one of the most frequent musculoskeletal disorders characterized by sustained tissue inflammation and oxidative stress, accompanied by extracellular matrix remodeling. Patients suffering from this pathology frequently experience pain, swelling, stiffness, and muscle weakness. Current pharmacological interventions are based on nonsteroidal anti-inflammatory drugs; however, the effectiveness of these strategies remains ambiguous. Accumulating evidence supports that oral supplementation of natural compounds can provide preventive, and possibly curative, effects. Vitamin C (Vit C), collagen peptides (Coll), resveratrol (Res), and astaxanthin (Asx) were reported to be endowed with potential beneficial effects based on their anti-inflammatory and antioxidant activities. Here, we analyzed the efficacy of a novel combination of these compounds (Mix) in counteracting proinflammatory (IL-1β) and prooxidant (H2O2) stimuli in human tenocytes. We demonstrated that Mix significantly impairs IL-6-induced IL-1β secretion, NF-κB nuclear translocation, and MMP-2 production; notably, a synergistic effect of Mix over the single compounds could be observed. Moreover, Mix was able to significantly counteract H2O2-triggered ROS production. Together, these results point out that Mix, a novel combination of Vit C, Coll, Resv, and Asx, significantly impairs proinflammatory and prooxidant stimuli in tenocytes, mechanisms that contribute to the onset of tendinopathies.

Progressive Loss of Acromioclavicular Joint Reduction Correlated with Progressive Clavicular Tunnel Widening after Coracoclavicular Stabilization in Acute High-Grade Acromioclavicular Joint Injury

Objectives: This study aimed to compare 24-month radiographic follow-ups of clavicular tunnel widenings (CTWs) and coracoclavicular distances (CCDs) and examine correlations between these measurements in patients following combined coracoclavicular stabilization and acromioclavicular capsule repair in treatment of acute high-grade acromioclavicular joint injury. Methods: This retrospective study reviewed the records of patients with acute Rockwood type V acromioclavicular joint injury who underwent surgery within 3 weeks after their injury. All patients had follow-ups at 3 and 6 months and 1 and 2 years. The CTWs were measured on anteroposterior radiographs between the medial and lateral borders at the superior, middle and inferior levels of the tunnels. On anteroposterior radiographs of both clavicles, the CCDs were measured at the shortest distance between the upper border of the coracoid process and the inferior border of the clavicle and reported as the CCD ratio, which was defined as the ratio of the affected and unaffected clavicles. At the final follow-ups, clinical outcomes were assessed using American Shoulder and Elbow Surgeons (ASES) scores. Results: This study included seventeen men and six women with a mean age of 47.26 ± 10.68 years. At the final follow-ups, the mean ASES score of all patients was 95.28 ± 3.62. We found a significant correlation between the increase in the CTWs and the increase in the CCD ratios (Spearman's rho correlation coefficient range 0.578-0.647, all p-values < 0.001). Conclusions: We found long-term postoperative widening of the clavicular tunnels, which correlated positively with a gradual postoperative decline in the acromioclavicular joint alignment reductions.

Quality of Postoperative Pain Management in Orthopedic Patients and Its Impact on Sleep Quality and Patient Satisfaction: An Integrative Review

Pain is one of the most common manifestations in the postoperative stage and it has a detrimental effect on both sleep and patient satisfaction. Consequently, this integrative review seeks to identify the outcomes of pain management specifically concerning sleep quality and patient satisfaction among the patients receiving orthopedic surgeries. In a stepwise manner, peer-reviewed articles manually searched in four databases including Scopus, Science Direct, PubMed, and CINAML (Cumulated Index to Nursing and Allied Health Literature) published between 2019 and 2023 were selected. The current review finally encompassed 22 studies. The review elaborates and reaffirms the notion that pain after surgery is still a critical issue that impacts the quality of patients' sleep as well as their overall satisfaction. Chronic sleep disturbance is generally linked with pain while other factors such as light exposure and hospital environment were found to influence sleep quality. It is thus crucial to develop clear multifaceted pain management guidelines that include patient-tailored pharmacological and non-pharmacological interventions aimed at helping patients recover better, sleep better, and be satisfied with the procedures and results.

Arthroscopic Bankart Repair With Remplissage in Anterior Shoulder Instability Results in Fewer Redislocations Than Bankart Repair Alone at Medium-term Follow-up of a Randomized Controlled Trial

BACKGROUND

A multicenter, double-blinded randomized controlled trial comparing isolated Bankart repair (NO REMP) to Bankart repair with remplissage (REMP) reported benefits of remplissage in reducing recurrent instability at 2 years postoperative. The ongoing benefits beyond this time point are yet to be explored.

PURPOSE

To (1) compare medium-term (3 to 9 years) outcomes of these previously randomized patients undergoing isolated Bankart repair (NO REMP) or Bankart repair with remplissage (REMP) to manage recurrent anterior glenohumeral instability; (2) examine the failure rate, overall recurrent instability, and reoperation rate.

STUDY DESIGN

Randomized controlled trial; Level of evidence, 1.

METHODS

Recruitment and randomization for the original randomized trial occurred between 2011 and 2017. Patients ≥14 years diagnosed with recurrent traumatic anterior shoulder instability with an engaging Hill-Sachs defect of any size were included. Those with a glenoid defect >15% were excluded. In 2020, participants were contacted by telephone and asked standardized questions regarding ensuing instances of subluxation, dislocation, or reoperation on their study shoulder. "Failure" was defined as a redislocation, and "overall recurrent instability" was described as a redislocation or ≥2 subluxations. Descriptive statistics, relative risk, and Kaplan-Meier survival curve analyses were performed.

RESULTS

A total of 108 participants were randomized, of whom 50 in the NO REMP group and 52 in the REMP group were included in the analyses in the original study. The mean number of months from surgery to the final follow-up was 49.3 and 53.8 months for the NO REMP and REMP groups, respectively. Failure rates were 22% (11/50) in the NO REMP group versus 8% (4/52) in the REMP group. Rates of overall recurrent instability were 30% (15/50) in the NO REMP group versus 10% (5/52) in the REMP group. Survival curves were significantly different, favoring REMP in both scenarios.

CONCLUSION

For the treatment of traumatic recurrent anterior shoulder instability with a Hill-Sachs lesion and subcritical glenoid bone loss (<15%), a significantly lower rate of overall postoperative recurrent instability was observed with arthroscopic Bankart repair and remplissage than with isolated Bankart repair at a medium-term follow-up (mean of 4 years). Patients who did not receive a remplissage experienced a failure (redislocated) earlier and had a higher rate of revision/reoperation than those who received a concomitant remplissage.

Evaluating the Effect of Rotator Cuff Repair With Concomitant Distal Claviculectomy on 2 and 4 Year Reoperation Rates

BACKGROUND

The current literature has differing views on the efficacy of concomitant distal claviculectomy (DC) during rotator cuff repair (RCR) in preventing revision surgery. Our aim was to investigate the revision surgery rate between RCR with DC and RCR without DC.

METHODS

A retrospective cohort analysis was conducted using a national claims database. Patients undergoing open or arthroscopic primary RCR with or without concomitant DC were identified. The primary outcome was 4-year revision surgery rates. Univariate analysis was conducted using chi-square or Student t tests. Multivariable analysis was conducted using logistic regression, and an adjusted number needed to harm was calculated.

RESULTS

A total of 131,232 patients met inclusion criteria. After logistic regression, patients undergoing RCR with DC had higher odds of requiring a subsequent DC procedure [OR; 95% CI; P-value (1.49; 1.35-1.64; P < 0.001)] but lower odds of any revision surgery (0.87; 0.80-0.91; P < 0.001) within 4 years than those who underwent RCR without DC.

CONCLUSION

Although associated with a lower rate of overall revision surgeries within 2 and 4 years of RCR, those who underwent RCR with DC were 85% more likely at 2 years and 49% more likely at 4 years to undergo revision surgery of the distal clavicle than those without concomitant DC.

Comparative efficacy of aspirin versus direct oral anticoagulants for venous thromboembolism prophylaxis following primary total hip arthroplasty or total knee arthroplasty: A systematic review and meta-analysis of randomised controlled trials

Introduction

Venous thromboembolisms (VTEs), including deep vein thrombosis (DVT) and pulmonary embolisms (PE), are common after total knee (TKA) and hip arthroplasty (THA). Recent studies suggest that aspirin effectively prevents VTE following major orthopaedic surgery. This meta-analysis compares randomised controlled trials (RCTs) evaluating aspirin versus direct oral anticoagulants (DOACs) for VTE prevention after primary THA and TKA.

Methods

We included RCTs from 2017 to 2023 that looked at aspirin versus DOACs for VTE prophylaxis in primary THA and TKA. A search strategy was conducted which used Boolean operators and MESH terms. Primary outcomes included VTE rates, symptomatic, asymptomatic DVT and PE. Secondary outcomes were mortality and bleeding complications. Statistical analysis was performed using REVMAN software. An odds ratio with a 95% confidence interval was generated for the pooled studies. Heterogeneity was assessed using the I 2 variable, and publication bias was evaluated with a funnel plot.

Results

Seven RCTs with 3967 patients were included for analysis. Rivaroxaban 10 mg OD was compared to varying doses of aspirin (81-300 mg). There were no significant differences between the groups in the incidence of VTE (OR: 1.21, 95% CI: 0.72-2.01), PE (OR: 1.01, 95% CI: 0.39-2.61), asymptomatic DVT (OR: 1.39, 95% CI: 0.64-3.00), suspected DVT (OR: 1.13, 95% CI: 0.49-2.61) and major bleeding (OR: 0.84, 95% CI: 0.55-1.27).

Discussion

Aspirin is as effective as rivaroxaban for primary thromboprophylaxis post-THA and TKA, without increased incidence of complications. Further research is needed to determine the optimal dosing regimen of aspirin and its long-term efficacy in preventing VTE.

Intercondylar T-Type Distal Humerus Fracture in a 10-Year-Old: A Case Report

CASE

A 10-year-old, postmenarchal girl presented to the emergency department with a closed, displaced, intercondylar T-type distal humerus fracture. Open reduction and internal fixation was performed 3 days following initial presentation. The patient healed but experienced elbow stiffness in the 7 months following the procedure. Implant removal and capsular release were performed at that time. At the 31-month follow-up, the patient reported satisfactory elbow functionality.

CONCLUSION

There is limited literature available discussing optimal management and associated outcomes of intercondylar T-type distal humerus fractures in the young-adolescent population. This report presents a possible method for management of the initial injury and the most common associated complication.

Shoulder MRI parameters in anticipating anterior shoulder dislocation: Are they a reliable and reproducible tool in clinical practice?

BACKGROUND

Anterior shoulder dislocation (ASD) is a frequently observed musculoskeletal injury that is often encountered in the context of sports activities or as a result of trauma. Several magnetic resonance imaging (MRI) parameters have been previously investigated for the purpose of characterizing the anatomical features, which could potentially be responsible for the episodes of instability. These measurements have the potential to identify patients who are susceptible to dislocation. Consequently, ensuring the reliability and consistency of these measurements is crucial in the diagnosis and the management of athletic or traumatic shoulder injuries.

METHODS

A group of four students, who had no previous experience in reading MRI series, were selected to perform radiographic measurements on specific parameters of MRI scans. These parameters were glenoid version, glenoid depth, glenoid width, humeral head diameter, humeral containing angle, and the ratio of humeral head diameter to glenoid diameter. The four participants conducted two distinct readings on a total of 28 sets of shoulder MRI scans. Simultaneously, the aforementioned measures were assessed by a consultant shoulder surgeon.

RESULTS

A total of 1512 measurements were categorized into nine sets: eight from students' measurements (two per student) and one from the consultant. Intra-rater reliability assessed by the intra-class correlation (ICC) test indicated excellent or good reliability for all parameters (p < 0.05), with glenoid depth showing the highest (0.925) and humeral-containing angles the lowest (0.675) ICC value. Inter-rater correlation, also evaluated using ICC, demonstrated strong correlation (p < 0.05), with glenoid diameter having the highest ICC score (0.935) and glenoid depth the lowest (0.849). Agreement analysis, expressed by Cohen's Kappa test, revealed substantial agreement (p < 0.05) for all parameters, with humeral head diameter having the highest agreement (0.90) and humeral-containing angle the lowest (0.73).

CONCLUSION

In this study, intra- and inter-rater MRI parameters are substantially concordant. Credibility comes from these reliability and agreement analyses' statistical significance. Glenoid diameter and depth are the most reliable intrarater and interrater, respectively. Best agreement was with the humeral-containing angle. These data demonstrate repeatability and clinical relevance.

The History and Evolution of the Open Labral Repair with Capsular Shift for Shoulder Instability

PURPOSE OF REVIEW

The purpose of this review is to describe the evolution of the open labral repair with capsular shift, including the current role of this procedure in the treatment of shoulder instability.

RECENT FINDINGS

Currently, a subset of patients - high-level collision/contact sport athletes, patients with significant inferior or multi-directional instability, and individuals with failed arthroscopic Bankart repair without bone loss - may experience benefit from undergoing open Bankart repair with capsular shift. Surgeons performing open stabilization can benefit from instrumentation and anchors developed to assist with arthroscopic techniques. Understanding the history and evolution behind the procedure not only allows the surgeon to appreciate principles behind an arthroscopic approach, but also permits the utilization of an open approach when required by patient pathology and risk factors.

Ellipsoidal patellar bone tunnel fixation with Toggleloc suspension system for medial patellofemoral ligament reconstruction: A 5 years follow-up

BACKGROUND

This study aimed to evaluate the clinical and radiological features of the patella fixation technique using Toggleloc suspension system in a single ellipsoidal blind patellar tunnel during medial patellofemoral ligament (MPFL) reconstruction.

METHODS

This study included 52 patients (25 men, 27 women) who underwent MPFL reconstruction using a semitendinosus tendon graft. The graft was fixed to the ellipsoidal single blind tunnel opened on the medial side of the patella with an endobutton and was fixed to the femoral tunnel by using bioabsorbable screw. Clinical scores (Kujala score, Lysholm score, Tegner activity score and the visual analog scale [VAS] score) were evaluated preoperatively and at the end-follow up. Preoperative and postoperative radiological measurements (trochlea depth, sulcus angle, patellar height, patellar congruence angle, patellar tilt angle and lateral patellofemoral angle) were evaluated with X-ray (Merchant X-ray, anteroposterior and lateral radiography) and computed tomography (CT) of the knee.

RESULTS

Postoperative patellar redislocation or subluxation was not observed in any patient. Patellar congruence angle, patellar tilt angle and lateral patellofemoral angle mean values were found to return to normal values in the postoperative period and the results were statistically significant. Also statistically significant improvement in all clinical scores postoperatively. According to the Insall-Salvati index (ISI) and Caton-Deschamps index (CDI) on lateral radiography of the knee at 30° flexion, patellar height decreased in the postoperative period statistically significant. The CDI was above 1.3 in 17 (%32) of our patients. Thirteen of these values decreased to normal values. No radiological progression of patellofemoral osteoarthritis was observed in all patients at the final follow-up evaluation.

CONCLUSION

In cases of patellofemoral instability, fixation of the tendon graft in blind ellipsoid tunnel using the Toggleloc suspension system provides satisfactory patellar graft fixation strength, significant functional improvement and a low failure rate.

Biceps tendon autograft augmentation for rotator cuff and instability procedures: a narrative review

Rotator cuff tears (RCT) and instability are the most common surgically treated shoulder pathologies. The concept of augmentation using the long head of the biceps tendon (LHBT) autograft was created to improve the results of surgical treatment of these pathologies, especially in cases of chronic and massive injuries. The popularity of using the LHBT for augmentation is evidenced by the significant number of publications on this topic published in the last 3 years; however, only one systematic review has been published regarding only LHBT augmentation for massive RCTs. Several studies comparing partial repair with partial repair and additional LHBT augmentation for RCT showed superior clinical outcomes and lower re-tear rates when LHBT augmentation was performed. There is a rising popularity of using LHBT as an autograft to perform superior capsule reconstruction (SCR) in case of irreparable rotator cuff tears. In recent years, shoulder stabilization by arthroscopic Bankart repair with biceps augmentation has been promoted with very promising short-term results. The evidence provided by studies appears to be sufficient to recommend the use of LHBT for augmentation whenever necessary; however, larger studies with long-term follow-up are needed.
