Does primary treatment of proximal humerus fractures show favourable functional outcomes over secondary treatment with reverse shoulder arthroplasty?

Background: This multicentre retrospective cohort study assessed whether functional outcomes after primary reverse shoulder arthroplasty (RSA) are favourable compared to secondary placement in elderly patients with displaced proximal humerus fractures (PHFs).

Methods: Fifty-three patients with primary and 32 with secondary RSA were included. Patient-reported outcome measures (PROMs) were assessed: Constant-Murley Score (CMS), Oxford Shoulder Score (OSS), Disabilities of the Arm, Shoulder and Hand (DASH) score, and Visual Analogue Scale (VAS).

Two-year follow-up of the SMR stemless platform shoulder system: a multicenter, prospective clinical study.

Background: The use of stemless shoulder arthroplasty for osteoarthritis has grown substantially over the past decades. The goal of this study is to evaluate the clinical and radiological outcomes of the Lima SMR stemless anatomic and reverse total shoulder arthroplasty.

Methods: Seventy-three implants in 73 patients (61 anatomic total shoulder arthroplasties [aTSAs] and 12 reverse shoulder arthroplasties [RSAs]) were analyzed with a minimum follow-up of 2 years.

Diagnostic value of a preoperative acromioclavicular injection for symptomatic acromioclavicular osteoarthritis: a retrospective study of cross-sectional midterm outcomes.

Background: It is essential to distinguish between symptomatic- and asymptomatic radiographic acromioclavicular (AC) osteoarthritis (OA) because AC-targeted physical examinations are dubious. This study aimed to determine the diagnostic value of a preoperative AC injection in discriminating between symptomatic- and asymptomatic radiographic AC OA based on patient arthroscopic distal clavicle resection (aDCR) outcomes.

Methods: Forty-eight patients who underwent aDCR for AC OA were included.

Anterosuperior versus deltopectoral approach for primary reverse total shoulder arthroplasty.

Aims: The current evidence comparing the two most common approaches for reverse total shoulder arthroplasty (rTSA), the deltopectoral and anterosuperior approach, is limited. This study aims to compare the rate of loosening, instability, and implant survival between the two approaches for rTSA using data from the Dutch National Arthroplasty Registry with a minimum follow-up of five years.

Methods: All patients in the registry who underwent a primary rTSA between January 2014 and December 2016 using an anterosuperior or deltopectoral approach were included, with a minimum follow-up of five years.

Primary reverse total shoulder arthroplasty for fractures requires more revisions than for degenerative conditions 1 year after surgery: an analysis from the Dutch Arthroplasty Register.

Background: Although reverse total shoulder arthroplasty (RTSA) is considered a viable treatment strategy for proximal humeral fractures, there is an ongoing discussion of how its revision rate compares with indications performed in the elective setting. First, this study evaluated whether RTSA for fractures conveyed a higher revision rate than RTSA for degenerative conditions (osteoarthritis, rotator cuff arthropathy, rotator cuff tear, or rheumatoid arthritis). Second, this study assessed whether there was a difference in patient-reported outcomes between these 2 groups following primary replacement.

Mid- to long-term success rate and functional outcomes of acromioclavicular injections in patients with acromioclavicular osteoarthritis.

Background: Acromioclavicular (AC) osteoarthritis (OA) is a frequent pathology of the shoulder in elderly patients. Drug injection plays an important role in treatment of AC OA. Literature has demonstrated excellent short-term results regarding shoulder function and pain.

Prognostic factors associated with failure to return to sport following primary arthroscopic Bankart repair: a retrospective multicenter study.

Background: Even though many studies have been published regarding return-to-sport (RTS) rates following arthroscopic Bankart repair (ABR), evidence regarding prognostic factors for which patients do not RTS is limited. The aim of this study was to identify prognostic factors that are associated with failure to RTS and failure to return to preinjury level of sport (RTPS) following primary ABR. The hypothesis was that prognostic factors for failure to RTS and failure to RTPS would be similar to those predisposing recurrence.

Ninety-day complication rate based on 532 Latarjet procedures in Dutch hospitals with different operation volumes.

Background: In this study, we aimed to provide insight into the 90-day complication rates following the Latarjet procedure. Data from 2015 were collected from multiple hospitals in the Netherlands, with different volumes of Latarjet procedures. Our second aim was to examine which patient and surgical factors were associated with complications.

Role of Delay Between Injury and Surgery on the Outcomes of Rotator Cuff Repair: A Systematic Review and Meta-analysis.

Background: Outcomes of rotator cuff repair (RCR) are influenced by several well-described factors, but the role of delay from injury to surgery on the outcomes is not clear.

Purpose: To assess the role of delay to surgery on the outcomes of RCR in the literature.

Study Design: Systematic review with meta-analysis; Level of evidence, 4.

Long-term results of the uncemented resurfacing shoulder hemiarthroplasty (Global Conservative Anatomic Prosthesis).

Background: Treatment with uncemented resurfacing shoulder hemiarthroplasty has proved to be viable for patients with end-stage osteoarthritis at short- and mid-term follow-up. This study was essential to determine whether those outcomes will endure. This study presents the long-term results of the Global Conservative Anatomic Prosthesis (CAP) uncemented resurfacing shoulder hemiarthroplasty (DePuy Synthes, Warsaw, IN, USA).

Repair versus reconstruction for proximal anterior cruciate ligament tears: a study protocol for a prospective multicenter randomized controlled trial.

Background: For active patients with a tear of the anterior cruciate ligament (ACL) who would like to return to active level of sports, the current surgical gold standard is reconstruction of the ACL. Recently, there has been renewed interest in repairing the ACL in selected patients with a proximally torn ligament. Repair of the ligament has (potential) advantages over reconstruction of the ligament such as decreased surgical morbidity, faster return of range of motion, and potentially decreased awareness of the knee.

Age, activity level and meniscus injury, but not tear location, tibial slope or anterolateral ligament injury predict coping with anterior cruciate ligament injury.

Introduction: Early recognition of potential predictors on the success of conservative treatment of anterior cruciate ligament (ACL) is important, as appropriate treatment can be applied to each individual patient. The goal of this study is to assess the patient demographic and radiological parameters that predict coping with ACL injuries.

Methods: All patients presenting with a complete ACL injury between 2014 and 2018 at our clinic were included.

Results of stemless shoulder arthroplasty: a systematic review and meta-analysis.

Stemless shoulder arthroplasty relies solely on cementless metaphyseal fixation and is designed to avoid stem-related problem such as intraoperative fractures, loosening, stress shielding or stress-risers for periprosthetic fractures.Many designs are currently on the market, although only six anatomic and two reverse arthroplasty designs have results published with a minimum of two-year follow-up.Compared to stemmed designs, clinical outcome is equally good using stemless designs in the short and medium-term follow-up, which is also the case for overall complication and revision rates.

Humeral Retroversion (Complexity of Assigning Reference Axes in 3D and Its Influence on Measurement): A Technical Note.

Background: Humeral retroversion (RV) is important to the study of shoulder function and reconstruction. This study tests the hypothesis that clinically obtained computer tomography (CT) measurements for humeral RV (off-axis measurements) differ from those obtained after reformatting the image slice orientation so that the humeral shaft is perpendicular to the gantry (coaxial measurements) and explores deviations from true RV.

Materials And Methods: A custom-built application created in Mathematica was used to explore the effect of altering the humeral orientation on slice angle acquisition by 3D imaging technologies, on the perceived angle of RV from the 2D-projection of the reference axes.

The Impact of Minimally Invasive Treatment for Rotator Cuff Calcific Tendinitis on Self-Reported Work Ability and Sick Leave.

Purpose: To examine the impact of rotator cuff calcific tendinitis on patients' self-reported work ability and sick leave, to compare work ability and sick leave with shoulder function after minimally invasive treatment, and to assess which prognostic factors influence the change in work ability.

Methods: A prospective cohort was analyzed in this study. The primary outcome measure was the single-question work ability score (0-10 points).

Conversion to reverse shoulder arthroplasty fifty-one years after shoulder arthrodesis: A case report.

Background: Patients with a shoulder arthrodesis generally experience restriction in range of motion and limitations in activities of daily living. In addition, up to one-third of the patients deals with serious peri scapular pain. The conversion of a shoulder arthrodesis in a reverse shoulder arthroplasty (RSA) has been described as an effective treatment to achieve better function and decreased pain, although literature is sparse.

Quantifying the minimal and substantial clinical benefit of the Constant-Murley score and the Disabilities of the Arm, Shoulder and Hand score in patients with calcific tendinitis of the rotator cuff.

Background: To aid the interpretation of clinical outcome scores, it is important to determine the measurement properties. The aim of this study was to establish the minimal clinically important difference (MCID) and substantial clinical benefit (SCB) for the Constant-Murley score and Disabilities of the Arm, Shoulder and Hand score in patients with long-lasting rotator cuff calcific tendinitis treated with high-energy extracorporeal shockwave therapy and ultrasound guided needling. The secondary purpose was to assess the responsiveness of both questionnaires and to identify variables associated with achieving the MCID and SCB.

Capsulorraphy with Achilles allograft augmentation for shoulder instability in patients with Ehlers-Danlos syndrome.

Background: Surgical management of shoulder instability in patients with Ehlers-Danlos syndrome (EDS) remains challenging secondary to the pathologic nature of their connective tissue. Allograft reconstruction of the shoulder capsule in EDS has the potential to increase stability by providing healthier connective tissue. The purpose of this study was to report the surgical technique and outcome of open capsulorraphy and augmentation of the anterior capsule with an Achilles tendon allograft in patients with shoulder instability in the setting of EDS.

Treatment of coracoid process fractures: a systematic review.

Introduction: The coracoid process is a small hook-shaped feature on the scapula and a key structure of the superior shoulder suspensory complex (SSSC). Fractures of the coracoid are rare. Therefore, no consensus exists regarding treatment of coracoid process fractures.

Comparing Ultrasound-Guided Needling Combined With a Subacromial Corticosteroid Injection Versus High-Energy Extracorporeal Shockwave Therapy for Calcific Tendinitis of the Rotator Cuff: A Randomized Controlled Trial.

Purpose: To compare clinical and radiographic outcomes after treatment with standardized high-energy extracorporeal shock wave therapy (ESWT) and ultrasound-guided needling (UGN) in patients with symptomatic calcific tendinitis of the rotator cuff who were nonresponsive to conservative treatment.

Methods: The study was designed as a randomized controlled trial. The ESWT group received ESWT (2000 pulses, energy flux density 0.

Overstuffing in resurfacing hemiarthroplasty is a potential risk for failure.

Purpose: Literature describes the concern of an overstuffed shoulder joint after a resurfacing humeral head implant (RHHI). The purpose of this study was to evaluate inter-observer variability of (1) the critical shoulder angle (CSA), (2) the length of the gleno-humeral offset (LGHO), and (3) the anatomic center of rotation (COR) in a patient population operated with a Global Conservative Anatomic Prosthesis (CAP) RHHI. The measurements were compared between the revision and non-revision groups to find predictive indicators for failure.
