Reverse shoulder arthroplasty with a 155° neck-shaft angle inlay implant design without reattachment of the subscapularis tendon results in satisfactory functional internal rotation and no instability: a cohort study.

BACKGROUND: The aim of this study was to use the Activities of Daily Living which require Internal Rotation (ADLIR) questionnaire to assess the functional internal rotation in patients who had undergone reverse shoulder arthroplasty (RSA) without reattachment of the subscapularis (SSc) tendon at a minimum follow-up of 2 years. The secondary aim was to report the objective range of motion (ROM) and the rate of postoperative instability. MATERIALS AND METHODS: All consecutive primary RSA procedures without reattachment of the SSc tendon that were performed using a Delta Xtend prosthesis (an inlay system with a 155° neck-shaft angle) between January 2015 and December 2020 were identified to ensure a minimum follow-up of 2 years. Patients were contacted and requested to fill in several questionnaires, including the ADLIR and Auto-Constant scores. RESULTS: In total, 210 patients met the inclusion criteria; among those patients, 187 could be contacted and 151 completed questionnaires (response rate: 81%). The SSc tendon was fully detached without repair in all cases, and a superolateral approach was used in 130 (86%) cases. The median follow-up was 4.5 years (range: 2.0-7.6). At final follow-up, the mean ADLIR score was 88/100 (interquartile range (IQR): 81-96). The median level reached in internal rotation was the 3rd lumbar vertebra (IQR: lumbosacral region-12th thoracic vertebra). Of the 210 eligible patients, one required a revision for a dislocation within the first month after primary surgery. With regards to regression analysis with ADLIR score as the outcome, none of the factors were associated with the ADLIR score, although age and smoking approached significance (0.0677 and 0.0594, respectively). None of the explanatory variables were associated with ROM in internal rotation (p > 0.05). CONCLUSIONS: This study demonstrates that satisfactory ADLIR scores and internal rotation ROM were obtained at mid-term follow-up after RSA leaving the SSc detached. Leaving the SSc detached also did not lead to high instability rates; only one out of 210 prostheses was revised for dislocation within the first month after primary surgery.

Arthroscopic posterior capsulolabral repair grants adequate outcomes in shoulders with posterior instability without glenoid cartilage lesions.

INTRODUCTION: Posterior capsulolabral repair (posterior Bankart) is effective to restore shoulder stability and relieve pain, though a recent meta-analysis reported recurrent instability in 9.5% of patients, and that only 62.7% were able to resume sports. The purpose of this study was to assess the outcomes of arthroscopic posterior capsulolabral repair in a population of unselected patients, in terms of recurrence of instability, clinical scores, and return to sports. METHODS: The authors retrospectively studied a consecutive series of 22 patients that underwent posterior capsulolabral repair between 2009 and 2019. Patients were assessed before posterior capsulolabral repair and at a minimum follow-up of 24 months, in terms of subjective shoulder value (SSV), Western Ontario Shoulder Instability Index (WOSI), as well as level of sport. Following surgery, all complications, reoperations or episodes of instability were noted. RESULTS: The cohort comprised 21 men (95%) and 1 woman (5%), aged 38.8 ± 12.5 years (range 17-61) at index surgery. Of the 20 patients that performed sports, only 2 (10%) stopped sports after surgery, while 18 resumed their main sport (90%). At a follow-up of 65.4 ± 34.8 months (range 25-146), the SSV was 85.1 ± 14.7, pain on VAS was 1.9 ± 2.1, and the Constant-Murley score was 71.6 ± 17.9. Five patients had subjective instability without dislocation (23%). Nine patients (41%) had no pain (0 points), 6 patients (27%) had mild pain (1-2 points), 4 patients (18%) had moderate pain (3 points), while 3 patients (14%) had severe pain (5-8 points). CONCLUSION: Arthroscopic posterior capsulolabral repair prevented recurrent dislocation in patients with posterior shoulder instability at a minimum follow-up of 2 years, despite persistent pain in 32%, and subjective instability in 23%. These complications were mainly observed in patients with work-related accidents and glenoid cartilage lesions. LEVEL OF EVIDENCE: III, case series.

Outcomes of Secondary Arthroscopic Distal Clavicle Resection for Shoulders With Symptomatic Acromioclavicular Joint Arthropathy After Isolated Rotator Cuff Repair With Complete Tendon Healing.

Background: Recent meta-analyses have advised against distal clavicle resection (DCR) as an adjuvant procedure during rotator cuff repair (RCR), whether performed routinely or in shoulders diagnosed with symptomatic acromioclavicular joint (ACJ) arthropathy. However, the efficacy of DCR as a secondary procedure in patients with persistent pain attributed to symptomatic ACJ arthropathy remains unknown. Purpose: To evaluate outcomes of secondary DCR in patients with failed nonoperative treatment of symptomatic ACJ arthropathy after isolated RCR with complete tendon healing. Study Design: Case series; Level of evidence, 4. Methods: Between 2008 and 2018, the senior surgeon performed isolated RCR in 1935 patients, of which 23 (1.2%) presented with ACJ pain and discomfort at ≥12 months after the index RCR, despite complete healing of repaired tendons. Those 23 patients underwent secondary DCR, as ACJ arthropathy was confirmed clinically and radiographically. Clinical assessment before DCR included the Subjective Shoulder Value (SSV) and pain at rest. Clinical assessment at >12 months after DCR included the SSV, pain at rest, Constant-Murley score, range of motion, and satisfaction. Pre- and post-DCR SSV and pain scores were compared. Results: Of the initial cohort, 5 patients did not consent to the use of their data, leaving 18 patients aged 53.3 ± 7.6 years (mean ± SD; range, 39-68 years) for outcome assessment. At a mean follow-up of 7.0 ± 3.1 years after DCR, the SSV significantly improved from 58.7 ± 17.2 to 76.1 ± 20.2 (P < .001), and the pain at rest significantly decreased from 4.7 ± 1.5 to 2.8 ± 1.9 (P < .001). At final follow-up, the Constant-Murley score was 70.2 ± 21.0. Of 18 patients, 15 had none or mild residual pain (0-2; 83%), while 3 had substantial residual pain (5 or 6; 17%). Only 1 of the 3 patients with substantial residual pain had a poor SSV score (20 points) and was against opting for DCR in retrospect. No patient had infections or gross ACJ instability after DCR. Conclusion: Secondary DCR for cases of symptomatic ACJ arthropathy after isolated RCR with complete tendon healing reduced pain in 83% of patients, and 94% were satisfied and would undergo secondary DCR again.

A pilot-study focusing on internal rotation after reverse total shoulder arthroplasty using the Activities of Daily Living which require Internal Rotation (ADLIR) score.

Background: Loss of internal rotation remains an issue after reverse total shoulder arthroplasty (RTSA). Our goal is to define the expected functional internal rotation after RTSA using the Activities of Daily Living which require Internal Rotation (ADLIR) score in a homogenous population of patients treated with RTSA. Methods: 35 patients with a minimum follow-up of two years after RTSA were evaluated using the ADLIR and Constant-Murley questionnaires. A correlation between the ADLIR and Constant score was investigated and the internal validity of the ADLIR score used in a RTSA patient population was measured using Cronbach's alpha coefficient. The impact of internal rotation on the total rotational arc of motion was defined. Results: Excellent results were recorded for both the Constant score (79 ± 18) and ADLIR score (88 ± 16). Pearson's correlation coefficient was r = 0,84 (p-value <0,001). The ADLIR score showed a high reliability for all questions. Conclusions: The ADLIR score has proven to be a useful addition in the post-operative evaluation of patients treated with RTSA. Further studies are needed to investigate the evolution of the ADLIR score from pre- to postoperatively in order to determine the clinical and predictive value of this score. Level of evidence: Level IV - Observational study.

Food Accessibility in the Suburbs of the Metropolitan City of Antwerp (Belgium): A Factor of Concern in Local Public Health and Active and Healthy Aging.

Population aging and declining birth rates are key demographic trends of the 21st century. While the overall life expectancy and healthy life years increase, the quality of life and functional capacity worsens due to non-communicable diseases strongly related to aging. Therefore, aging citizens are often vulnerable to food insecurity. The aim of this paper is to provide insights into the physical accessibility of fresh food and possible alternatives within the setting of an aging society in Antwerp (Belgium), a metropolitan city at the heart of the EU Reference Site 'Three Rivers Food Delta'. We demonstrate that a large number of the Antwerp suburban areas in which 15 to 25% of current inhabitants are already over 65 years old are confronted with problematic physical accessibility of food due to long walking distances to the nearest food shop. E-commerce has the potential to provide better access to fresh food. This is especially relevant for people with specific needs, such as health-related diets, dysphagia, and/or limited mobility. However, e-commerce introduces new inequalities, as those who would benefit the most from digital accessibility currently use it least. Hence, the organization of fresh food access requires a more thoughtful organization of the 'last mile' and possible alternatives to home delivery. This makes food accessibility an urgent factor of concern in public health and healthy aging in the Antwerp suburban areas.

A novel plating technique for Ideberg type 1 A glenoid fractures: a report of five patients.

BACKGROUND: Glenoid rim fractures are uncommon and generally associated with high complication rates. The most common treatment techniques include screw or anchor fixation. Here, we introduce a new fixation method to treat Ideberg type 1 A fractures. METHODS: A retrospective analysis was performed on patients treated with open reduction and plate fixation for Ideberg type 1 A fractures. The active range of motion capacity of both shoulders was recorded postoperatively. Constant-Murley score and Oxford disability index scores were used as outcome tools. RESULTS: Five patients (three men and two women) were evaluated; their mean age was 56 years (standard deviation (SD), 10 years). The mean follow-up period was 25 months (range, 6-69 months); all fractures healed radiologically during the follow-up period. The mean Constant-Murley score was 80.36 (SD 11.01); the mean Oxford disability index was 37 (SD 9). The subsequent flexion and external rotation of the injured shoulders were similar to those of the uninjured side (injured vs. uninjured side: flexion, 176 ± 5.4 vs. 178 ± 4.4; external rotation, 48 ± 10.9 vs. 60 ± 0). No patient showed signs of osteoarthritis, stiffness, instability, or chronic pain at the last follow-up. DISCUSSION: Open reduction and internal fixation with a plate is suitable for Ideberg type 1A glenoid fractures.

The 360 Double Lasso Loop for Biceps Tenodesis: Tips and Tricks.

The management of the intra-articular portion of the long head of the biceps tendon (LHB) is a recurring topic in every discussion about shoulder pain. In massive rotator cuff tears or in tears of the superior third of the subscapularis tendon, our approach is to systematically perform a tenodesis of the LHB. In this Technical Note, we present our arthroscopic technique for LHB tenodesis at the articular margin of the humeral head using a single anchor and a 360 double lasso loop. This technique guaranties a strong and efficient fixation of the biceps tendon and is reproducible when following the steps and tips and tricks outlined herein.

Coracoid process transfer for anterior shoulder instability : a pectoralis minor sparing method.

The Latarjet procedure alters scapulothoracic motion by releasing the pectoralis minor insertion to the coracoid process and by changing the vector of the conjoint tendon. The purpose of this study is to evaluate the feasibility of retaining the pectoralis minor insertion and a part of the conjoint tendon on to the remainder of the coracoid, and to evaluate the efficiency of the procedure in avoiding scapular dyskinesis, without concessions to glenohumeral stability. Since June 2017, a modification to the Latarjet procedure has been used in the treatment of posttraumatic anterior shoulder instability. The pectoralis minor insertion and a part of the conjoint tendon is retained on its anatomical position, by harvesting only the lateral part of the coracoid. We retrospectively enrolled the first 9 consecutively treated shoulders with a minimum of 6 months follow up and recorded scapulothoracic position and scapulothoracic motion, patient satisfaction, Oxford score, and Short Form (SF)-36. All patients underwent a radiographic review at final follow up. No scapular dyskinesis was observed at final follow- up. Radiographies consistently showed a bony spur at the original osteotomy site, suggesting a functional attachment of the pectoralis minor tendon to the scapula. Harvesting only the lateral part of the coracoid is technically feasible, efficient in treating anterior shoulder instability and avoids scapular dyskinesis. Level of evidence : Level IV, Retrospective Cohort study, Treatment study.

What Can We Expect Following Anterior Total Hip Arthroplasty on a Regular Operating Table? A Validation Study of an Artificial Intelligence Algorithm to Monitor Adverse Events in a High-Volume, Nonacademic Setting.

BACKGROUND: Quality monitoring is increasingly important to support and assure sustainability of the orthopedic practice. Surgeons in nonacademic settings often lack resources to accurately monitor quality of care. Widespread use of electronic medical records (EMR) provides easier access to medical information, facilitating its analysis. However, manual review of EMRs is highly inefficient. Artificial intelligence (AI) software allows for the development of algorithms for extracting relevant complications from EMRs. We hypothesized that an AI-supported algorithm for complication data extraction would have an accuracy level equal to or higher than manual review after total hip arthroplasty (THA). METHODS: A total of 532 consecutive patients underwent 613 THA between January 1 and December 31, 2017. A random derivation cohort (100 patients, 115 hips) was used to determine accuracy. After generation of a gold standard, the algorithm was compared to manual extraction to validate performance in raw data extraction. The full cohort (532 patients, 613 hips) was used to determine recall, precision, and F-value. RESULTS: AI accuracy was 95.0%, compared to 94.5% for manual review (P = .69). Recall of 96.0% (84.0%-100%), precision of 88.0% (33%-100%) and F-measure of 0.85 (0.5-1) was achieved for all adverse events. No adverse events were recorded in 80.6%, 1.3% required reintervention and 18.1% had "transient" events. CONCLUSION: The use of an automated, AI-supported search algorithm for EMRs provided continuous feedback on the quality of care with a performance level comparable to manual data extraction, but with greater speed. New clinical information surfaced, as 18.1% of patients can be expected to have "transient" problems.
