Angled BIO-RSA leads to better inclination and clinical outcomes compared to Standard BIO-RSA and eccentric reaming: A comparative study.

Background: Two surgical techniques were compared : Standard BIO-RSA, performed with a glenoid eccentric reaming along with a cylindric bone graft augmentation vs. the Angled BIO-RSA, performed with a glenoid concentric reaming and a defect correction with an angled bone graft. Methods: Patients undergoing RSA from January 2016 to April 2019, with one of the two techniques being performed, were retrospectively reviewed. Glenoids were classified according to Favard. Clinical (Constant-Murley, VAS and ROM) and radiographic (superior tilt correction) data were collected pre-operatively and at 12 months post-operatively. Results: 141 shoulders were included. Angled BIO-RSA group showed statistically significant better outcomes in terms of forward flexion (149.9° Vs 139.3°) and abduction (136.4° Vs 126.7°). The use of an Angled BIO-RSA showed a statistically significant better superior tilt correction (1.252° Vs 4.09°). Angled BIO-RSA, leads to a better inclination correction and a mean postoperative tilt value inferior to 5° in E1 and E3 differently from standard BIO-RSA. Discussion: Both techniques were able to correct glenoid superior inclination with excellent postoperative short-term results. However, angled BIO-RSA technique appears to be more effective in ensuring a correct inclination of the prosthetic glenoid component with better clinical outcomes.

The management of the long head of the biceps in rotator cuff repair: A comparative study of high vs. subpectoral tenodesis.

BACKGROUND: Tenodesis of the long head of the biceps (LHB) is commonly undertaken during arthroscopic rotator cuff repair. We assessed the clinical and structural outcomes after high arthroscopic tenodesis (HAT) or mini-open subpectoral tenodesis (ST). We hypothesized that the clinical and structural results after HAT and ST are similar. METHODS: We included 40 patients with rotator cuff tear and LHB tendinopathy. Twenty patients (7 women and 13 men; mean age: 57.9 years; range: 56-63 years) were treated using HAT, and 20 patients (8 women and 12 men; mean age: 58.5 years; range: 55-64 years) were treated using ST. Functional evaluation was performed preoperatively and at 6 weeks, 6 months, and 1 year after surgery, using the Constant Murley Score and Simple Shoulder Test scores; the LHB was evaluated using the LHB score. A Visual Analogue Scale was administered to all patients preoperatively and 2 days after surgery. RESULTS: The postoperative total and pain subscale's Constant scores were significantly higher in the ST group. Moreover, 2 LHB score values were significantly different between the groups. The postoperative LHB total score in the ST and HAT groups averaged 86.9 ± 4.1 (mean ± SD) points and 73.3 ± 6.4 points, respectively. The Pain/Cramps subscale in the ST and HAT groups averaged 47.1 ± 5.9 and 33.2 ± 4.6 points, respectively. The 2 groups showed no difference in Visual Analogue Scale values (5.5 in the HAT group; 5.8 in the ST group) postoperatively. One patient in the HAT group reported a secondary onset of Popeye deformity. CONCLUSION: Both high arthroscopic and mini-open ST of the LHB tendon produced reliably good functional results, but the ST group was associated with better postoperative clinical outcomes.

Return to Sport After Total Shoulder Arthroplasty and Hemiarthroplasty: A Systematic Review.

PURPOSE: One of the most frequent concerns of the increasing number of patients undergoing shoulder arthroplasty is the possibility to resume sport after surgery. This systematic review determined the rate of return to sport after total shoulder arthroplasty (TSA) and hemiarthroplasty (HA). MATERIALS AND METHODS: The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines were followed to perform this systematic review. A systematic electronic search was performed using the PubMed (MEDLINE), EMBASE, and Cochrane Library databases. All the studies analyzing the rates of reverse shoulder arthroplasties were pooled; data were extracted and statistically analyzed. Only studies with at least 10 adult patients recruited were considered. All studies had to relate return to sport after TSA or HA. RESULTS: A total of 76 studies were included for a total of 694 patients. The mean age and average follow-up were, respectively, 64.5 years (range: 24 to 92 y) and 4.5 years (range: 0.5 to 12 y). The mean rate of return to sport ranged from 49.3% to 96.4%. The mean time to resume sports was 8.1 months. The overall rate of return to sport after the procedures, according to a random effect model, was 83%. The mean level of sports at the time of the survey was worsened in 9.4% (±2.82%), improved or reported from good to excellent in 55.6% (±13.6%), and did not change in 40% (±1.4) of patients. CONCLUSIONS: On the basis of current available data, return to sports after TSA and HA is possible and is highly frequent. The subjective level of practice does not change or improve in most patients. More studies and better designed trials are needed to enrich the evidence on specific sport recovery after the procedure.

Return to sport after reverse total shoulder arthroplasty is highly frequent: a systematic review.

IMPORTANCE: One of the most frequent concerns of the increasing number of patients undergoing shoulder arthroplasty is the possibility to resume sport after surgery. OBJECTIVE: The aim of this systematic review was to determine the rate of return to sport after reverse total shoulder arthroplasty (RSA) and the subjective level of performance. EVIDENCE REVIEW: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines were followed to perform this systematic review. A systematic electronic search was performed using the PubMed (MEDLINE), Embase and Cochrane Library databases. All the studies analysing the rates were pooled; data were extracted and statistically analysed. The eligibility criteria were studies with at least 20 adult patients recruited. All studies had to relate return to sports after RSA. FINDINGS: A total of six studies were included for a total of 457 patients. Mean age and average follow-up were, respectively, 74.7 years (range 33-88 years) and 3.6 years (range 1-9.4 years). The mean rate of return to sport ranged from 60% to 93%. The mean time for resuming sports was 5.3 months. The overall rate of return to sport after reverse shoulder arthroplasty was 79%. The mean level of sports at the time of the survey was worsened in 7.9%, improved in 39.6% and had no change in 55.2% of the cases. CONCLUSIONS AND RELEVANCE: Based on the current available data, return to sports after reverse shoulder arthroplasty is possible and highly frequent. The subjective level of practice undergoes no change or improves in most of the cases. More studies and better-designed trials are needed in order to enrich the evidence on specific sports recovery after the procedure. LEVEL OF EVIDENCE: IV.

The Efficacy of Injections for Partial Rotator Cuff Tears: A Systematic Review.

(1) Background: Even though rotator cuff tears are the most frequent tendon injuries in adults, the effectiveness of conservatively treated partial-thickness tears still remains a matter of debate. The purpose of this review is to compare corticosteroid injections to other drugs in the treatment of partial rotator cuff tears, focusing on the effectiveness of this therapeutic modality in terms of pain and shoulder functionality. (2) Methods: A systematic electronic search was performed using the PubMed (MEDLINE), EMBASE and Cochrane Library databases. All studies comparing the use of corticosteroids and other infiltrative techniques in the treatment of partial lesions (excluding studies that considered subacromial impingement as inclusion criteria) were pooled, data were extracted and statistically analyzed. (3) Results: Nine studies were included in this systematic review. Those studies, composed by a total of 494 shoulders treated, have been published from 1985 to 2019. All compared techniques have shown a significant improvement over baseline condition. PRP (Platelet Rich Plasma) injections have been shown to be significantly more effective in both functional and pain control only in the long term. (4) Conclusions: None of the techniques prevail indisputably on the others. Anyway, the treatment of partial rotator cuff tears with PRP injections seems to lead to significantly better outcomes in terms of pain and shoulder function in long term follow up. Whereas in short and medium term follow up, PRP injections was superior only in terms of shoulder function. The small number of studies on prolotherapy did not enable us to provide an opinion on the outcomes of this technique.

The role of the subscapularis tendon in a lateralized reverse total shoulder arthroplasty: repair versus nonrepair.

PURPOSE: The reverse shoulder prost hesis (rTSA) is now implanted by the same percentage of anatomic shoulder prosthesis in the USA. Scapular notching and loss of extrarotation have been underlined as complication at long-term follow-up due to the Grammont design. The current trend to reduce those limits is to position both components lateralized. As the role of the subscapularis tendon in this new rTSA design is unclear, the purpose of this study is to quantify rTSA outcomes in patients with or without subscapularis tendon suture. METHODS: The surgery was performed by the same orthopaedic surgeon (F.F.), using a Aequalis Ascend™ Flex prosthesis (Tornier, Montbonnot, France) with a bone autograft. Forty-four patients underwent surgery with the tendon sutured, whereas 40 patients underwent the same surgery without repairing it. Patients were evaluated pre-operatively and at the last follow-up using Constant score, VAS, and ROM. The minimum and mean follow-ups were six and 16.6 months, respectively. RESULTS: All patients showed statistically significant improvement in pain and joint function following surgery. This study highlighted significant higher values in intrarotation and abduction, respectively, with and without suturing the subscapularis tendon. However, no significant differences were underlined in Constant score, VAS, forward flexion, extrarotation at 0° and 90° of abduction, and rate of instability. CONCLUSIONS: As predicted, significant clinical improvements were observed in both groups with some differences. These clinical results showed that the use of rTSA with lateralized humerus and bony increase offset leads to realistic clinical improvements with a low risk of instability without the need for compression and stabilization of the tendon.

Surgical management of osteonecrosis of the humeral head: a systematic review.

PURPOSE: Osteonecrosis of the humeral head is a rare diagnosis. The aim of this systematic review was to identify published studies and analyse the best clinical evidence available related to the surgical management of osteonecrosis of the humeral head. METHODS: A systematic electronic search was performed using the PubMed (MEDLINE), EMBASE and Cochrane Library databases. Published studies that reported the outcomes for adult patients treated surgically for osteonecrosis of the humeral head were included. The PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement was followed. RESULTS: Twelve studies were included: five prospective case series and seven retrospective case series. A total of 309 patients, comprising 382 shoulders, were included. Three main surgical procedures were evaluated: core decompression, hemi-arthroplasty and total shoulder arthroplasty. CONCLUSIONS: Based on the current available data, core decompression is a safe and effective option for treating low-grade osteonecrosis of the humeral head, while hemi-arthroplasty and total shoulder arthroplasty should be considered for high-grade osteonecrosis. More studies and better-designed trials are needed in order to enrich the evidence and enable researchers to draw stronger conclusions. Since osteonecrosis is an uncommon, though challenging disease, a proper knowledge of its treatment is needed. LEVEL OF EVIDENCE: IV.

Double-Row Repair Lowers the Retear Risk After Accelerated Rehabilitation.

BACKGROUND: Recently, an accelerated rehabilitation protocol after rotator cuff (RC) repair has been proposed for patients at risk of postoperative stiffness. PURPOSE: To investigate, in patients undergoing early accelerated mobilization, whether double-row (DR) repair provides better clinical outcomes and a lower retear rate compared with single-row (SR) configurations. STUDY DESIGN: Randomized controlled trial; Level of evidence, 1. METHODS: A total of 58 patients were randomized to undergo either SR or DR repair. After 2 years of follow-up, 12 men and 13 women (mean age, 61.8 years; range, 52-67 years) in the SR group and 15 men and 10 women (mean age, 58.9 years; range, 51-69 years) in the DR group were evaluated. To assess the retear rate, magnetic resonance imaging of the shoulder was performed at 2-year follow-up. The clinical evaluation was based on the modified University of California, Los Angeles (UCLA) shoulder score and range of motion (ROM) measurements. RESULTS: Magnetic resonance arthrography showed a significantly lower full-thickness retear rate for the DR group than for the SR group (8% vs 24%, respectively; P < .05). Conversely, at both 6-month and 2-year follow-up, there was no statistically significant difference in terms of the rate of stiffness in the SR and DR groups (8% vs 12% and 0% vs 0%, respectively; P > .05). No clinical differences were recorded regarding the UCLA score (SR group: mean, 32.6 [range, 30-35]; DR group: mean, 33.3 [range, 29-35]; P = .61) and ROM. CONCLUSION: In selected patients at a high risk of shoulder stiffness and therefore necessitating accelerated postoperative rehabilitation, DR repair of the RC could lower retear rates.

Volar locking plates versus K-wire/pin fixation for the treatment of distal radial fractures: a systematic review and quantitative synthesis.

INTRODUCTION: Volar locking plate and Kirschner wire/pin fixations are the most commonly used methods for surgical fixation of distal radius fractures. SOURCES OF DATA: A literature search was performed using PubMed, CINAHL, Cochrane Central and Embase Biomedical databases, selecting studies comparing two or more different surgical treatments including Kirschner wire fixation and volar locking-plate fixation. This systematic review was conducted following the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines. Methodological quality of all selected articles was assessed. AREAS OF AGREEMENT: A total of 14 publications (1306 patients) were included in this review, 10 of which were prospectively designed (8 randomized controlled trial). A total of 659 (50.5%) patients underwent volar locking plating (VLP group), while 647 of 1306 (49.5%) were treated with Kirschner wire/pin fixation (KW group). No differences were recorded in terms of ROM, grip strength, radiographic variables and total rate of complications. There is no clear superiority of either fixation method for the surgical management of distal radius fractures. AREAS OF CONTROVERSY: At a pooled analysis, VLP obtained statistically significant better DASH value compared to KW (18.1 ± 7.8 vs. 12.8 ± 6.4%, P = 0.026). Costs and surgical times were significantly higher for plate fixation. GROWING POINTS: Both techniques provide excellent clinical and radiographic results, without a clear superiority of either fixation method for the surgical management of distal radius fractures. RESEARCH: There is a need for more randomized trials performing standardized measurements at fixed follow-up, with results divided by subtypes of distal radius fractures.

Obesity as a risk factor for tendinopathy: a systematic review.

Purpose. In the last few years, evidence has emerged to support the possible association between increased BMI and susceptibility to some musculoskeletal diseases. We systematically review the literature to clarify whether obesity is a risk factor for the onset of tendinopathy. Methods. We searched PubMed, Cochrane Central, and Embase Biomedical databases using the keywords "obesity," "overweight," and "body mass index" linked in different combinations with the terms "tendinopathy," "tendinitis," "tendinosis," "rotator cuff," "epicondylitis," "wrist," "patellar," "quadriceps," "Achilles," "Plantar Fascia," and "tendon." Results. Fifteen studies were included. No level I study on this subject was available, and the results provided are ambiguous. However, all the 5 level II studies report the association between obesity measured in terms of BMI and tendon conditions, with OR ranging between 1.9 (95% CI: 1.1-2.2) and 5.6 (1.9-16.6). Conclusions. The best evidence available to date indicates that obesity is a risk factor for tendinopathy. Nevertheless, further studies should be performed to establish the real strength of the association for each type of tendinopathy, especially because the design of the published studies does not allow identifying a precise cause-effect relationship and the specific role of obesity independently of other metabolic conditions.
