Posterior shoulder instability.

Posterior shoulder instability (PSI) is defined by dynamic, recurrent and symptomatic partial or total loss of posterior joint contact. Anatomic risk factors comprise ligament hyperlaxity, glenoid retroversion or dysplasia, and high horizontal acromial morphology. Associated anatomic lesions comprise labrum lesions, posterior glenoid erosion and/or fracture, and anterior humeral head notching.

Pyrocarbon Hemi-Shoulder Arthroplasty Provides Satisfactory Outcomes Following Prior Open Latarjet.

Purpose: To assess the clinical and radiographic outcomes, at a minimum follow-up of 4 years, following HSA using pyrocarbon in patients that had prior open Latarjet.

Methods: The authors retrieved the records of 61 consecutive patients that underwent HSA with a pyrocarbon humeral head at 2 centers between December 2013 and October 2019. Eight patients (9 shoulders) had undergone previous Latarjet procedures without other surgical antecedents.

Long-term (minimum 10 years) survival and outcomes of pyrocarbon interposition shoulder arthroplasty.

Background: There are some major controversies surrounding the use and longevity of pyrocarbon interposition shoulder arthroplasty (PISA). The objective of this study was to investigate the long-term survival and outcomes (minimum 10-year) following PISA for osteoarthritis (OA) in young and active patients.

Methods: This was a retrospective review of prospectively collected data of patients who underwent PISA (InSpyre; Tornier-Stryker) for OA between 2009 and 2012.

Clinical results and computed tomography analysis of intuitive shoulder arthroplasty (ISA) stemless at a minimum follow-up of 2 years.

Background: The utilization of stemless anatomic total shoulder arthroplasty is on the rise. Epiphyseal fixation leads to radiological bone remodeling, which has been reported to exceed 40% in certain studies series. The aim of this study was to present the clinical and radiological outcomes of a stemless implant with asymmetric central epiphyseal fixation at an average follow-up of 31 months.

Background: To compare shoulder range of motion (ROM) in dominant vs. nondominant shoulder of competitive tennis players, and to determine whether shoulder ROM is different between younger and older players, or males and females.

Methods: A search was performed on PubMed, Embase, and Epistemonikos on December 18, 2023.

Intraoperative repair of functional subscapularis during RSA by deltopectoral approach could improve internal rotation but does not prevent anterior dislocation.

Introduction: The role of the subscapularis following reverse shoulder arthroplasty (RSA) remains controversial as repair could restore adequate internal rotation and shoulder stability, but might compromise external rotation. The purpose of this multi-centre study, on a large cohort of RSAs performed using the deltopectoral approach, was to determine the effect of subscapularis preoperative status and intraoperative repair on range of motion, clinical scores and rates of complications at a minimum follow-up of 2 years.

Hypothesis: Repair of a functional subscapularis grants better internal rotation and stability without compromising external rotation.

Better Constant Scores and Active Forward Elevation Using Deltopectoral Versus Anterosuperior Approach for Reverse Shoulder Arthroplasty: Matched Cohort Study.

Purpose: To determine, from a sizable cohort of reverse shoulder arthroplasty (RSA), whether the deltopectoral (DP) or anterosuperior (AS) approach grant better outcomes at a minimum follow-up of 24 months.

Methods: The authors reviewed 743 RSAs in patients with primary osteoarthritis (OA) with or without rotator cuff lesions and secondary OA due to rotator cuff tears. The DP approach was used in 540 and the AS approach in 203.

Insufficient evidence to confirm benefit of adjuvant distal clavicle resection during rotator cuff repair: a systematic review and meta-analysis.

The aim of this study is to determine whether adjuvant Distal Clavicle Resection (DCR) improves outcomes of Rotator Cuff Repair (RCR) in terms of ROM, clinical scores as well as reducing complications and/or reoperations. This systematic review conforms to the PRISMA guidelines. Studies were included if they compared outcomes of RCR with and without adjuvant DCR and reported on postoperative ROM, clinical scores, complications, and/or reoperations.

Pyrocarbon humeral heads for hemishoulder arthroplasty grant satisfactory clinical scores with minimal glenoid erosion at 5-9 years of follow-up.

Background: Hemishoulder arthroplasty (HSA) is a more conservative alternative to total shoulder arthroplasty for young and active patients with minimal glenoid erosion or deformity. Pyrocarbon humeral heads were introduced as an alternative to metallic humeral heads, which were associated with glenoid erosion in 28%-43%. The purpose of this study was to evaluate the progression of glenoid erosion and clinical scores of HSA using pyrocarbon humeral heads from short- (2-4 years) to midterm (5-9 years).

Factors that affect external rotation following reverse shoulder arthroplasty: a retrospective multi-centre study on 501 shoulders.

Introduction: The purpose of this multi-centre study was to assess external rotation in a large cohort following reverse shoulder arthroplasty (RSA) at a minimum follow-up of 2 years, and identify factors that influence postoperative and/or net-improvement of external rotation.

Methods: The authors retrospectively reviewed records of 743 RSAs performed between January 2015 and August 2017 by 16 surgeons that participated in a large national society symposium; 193 (25.7%) were lost to follow-up, 16 (2.

Midterm results of pyrocarbon interposition shoulder arthroplasty: good outcomes after posttraumatic osteonecrosis without malunion of the tuberosities.

Background: In vitro data demonstrate the potential benefits of the pyrocarbon as a bearing material against cartilage or bone. And pyrocarbon-free interposition arthroplasty has been used with positive outcomes for over 10 years for hand and wrist joint replacements. This study reports the midterm results of a Pyrocarbon Interposition Shoulder Arthroplasty (PISA) in primary and secondary glenohumeral osteoarthritis and in avascular osteonecrosis.

Low healing rates and moderate functional outcome after arthroscopic superior capsular reconstruction using a porcine xenograft.

Purpose: In the absence of arthropathy, symptomatic massive irreparable rotator cuff tears contribute to a therapeutic challenge for orthopedic surgeons. The concept of superior capsular reconstruction (SCR) was introduced as an option for these challenging cases. The purposes of this study were to evaluate the clinical outcome scores when using a decellularized porcine xenograft and to evaluate the graft healing and incorporation.

Arthroscopic rotator cuff repair: Is healing enough?

Hypothesis/background: Arthroscopic rotator cuff repair most commonly results in good clinical outcomes, however understanding of predictive factors influencing the final clinical outcome is limited.

Aim: The purpose of our study was to evaluate clinical outcomes of patients with healed supraspinatus tendon after arthroscopic rotator cuff repair and to identify its pre- and peri-operative predictive factors of good clinical results.

Methods: A multi-center prospective study followed up 188 patients, who had a healed tendon after an arthroscopic repair of isolated supraspinatus tear.

Osteoarthritis of the shoulder in under-50 year-olds: A multicenter retrospective study of 273 shoulders by the French Society for Shoulder and Elbow (SOFEC).

Introduction: Osteoarthritis (OA) of the shoulder in under-50 year-olds is rare, and treatment is delicate. Shoulder replacement incurs frequent long-term risk of progression and a high revision rate, making it unsuited to young active patients. The aim of the present study was to determine the epidemiology of shoulder OA in under-50 year-olds and to assess the clinical results of the various treatment options.

Prospective study of tendon healing and functional gain after arthroscopic repair of isolated supraspinatus tear.

Introduction: In case of failure of non-operative treatment of isolated supraspinatus tear, tendon surgery can improve shoulder function and alleviate pain. The present study hypothesis was that isolated supraspinatus repair shows good healing, with improved clinical results.

Materials And Methods: A prospective multicentre study followed up 199 patients (mean age, 57 years) for one year.

Benefits of distal clavicle resection during rotator cuff repair: Prospective randomized single-blind study.

Introduction: Rotator cuff tears often occur in combination with acromioclavicular (AC) arthropathy. But it can be difficult to separate pain caused by the rotator cuff tear from pain caused by the AC joint, despite clinical and other examinations. Distal clavicle resection (DCR) is increasingly being done at the same time as arthroscopic rotator cuff repair.

Long term term follow-up of tyrosine kinase inhibitors treatments in inoperable or relapsing diffuse type tenosynovial giant cell tumors (dTGCT).

Rationale: CSF1R tyrosine kinase inhibitors (TKI) and antibodies yield response rates and tumor control in patients with diffuse type tenosynovial giant cell tumors (dTGCT). The long term management of patients with dTGCT treated with TKI is however not known.

Patients And Methods: We conducted a retrospective single center study on the 39 patients with advanced and/or inoperable dTGCT referred to the Centre Leon Berard for a medical treatment.

Glenoid Cartilage Lesions Compromise Outcomes of Surgical Treatment for Posterior Shoulder Instability.

Background: Posterior shoulder instability is associated with nonspecific symptoms, including pain, subluxation, and functional impairment, which complicate its diagnosis and management. Owing to the rarity of the condition, there are no present decision tools for its diagnosis and treatment.

Purpose: To investigate demographic, lesional, and surgical factors that influence functional outcomes in patients treated for posterior shoulder instability.

Internal impingement of the shoulder in overhead athletes: Retrospective multicentre study in 135 arthroscopically-treated patients.

Background: Internal impingement of the shoulder (IIS) is the leading cause of chronic shoulder pain in overhead throwing athletes. No consensus exists about which techniques are optimal when surgery is in order. The available studies are limited by small sample sizes and short follow-ups.

Internal impingement of the shoulder: An international survey of 261 orthopaedic surgeons.

Background: Internal impingement of the shoulder (IIS) is a specific disorder of young overhead-throwing athletes that was first described in 1991. The many non-operative and surgical treatments suggested to date have produced mixed outcomes. The objective of this study was to compare the practices of surgeons in France versus other countries regarding the diagnosis and treatment of IIS.

Is posterosuperior contact a normal occurrence in the shoulder?

Unlabelled: Posterosuperior (or internal) impingement at the shoulder is defined as contact between the underside of the supraspinatus or infraspinatus tendons with the posterosuperior labrum during extreme external rotation and abduction. In many cases, this contact damages the tendon and causes mirror posterosuperior labrum deterioration. The primary aim of this study was to define whether this contact occurs normally in patients who do not have a rotator cuff tear.

Pyrolytic carbon humeral head in hemi-shoulder arthroplasty: preliminary results at 2-year follow-up.

Background: In patients with osteoarthritis (OA) and an intact rotator cuff, hemi-shoulder arthroplasty (HSA) can be a viable option as it offers the advantage of keeping the native glenoid intact. However, glenoid erosion has frequently been reported. The aim of this study was to report preliminary clinical results of HSA with a new pyrolytic carbon (pyrocarbon) humeral head.

Comparison of revision rates and radiographic observations of long and short, uncoated and coated humeral stem designs in total shoulder arthroplasty.

There is no consensus on outcomes of long short and uncoated coated uncemented stems in total shoulder arthroplasty (TSA).We reviewed the literature to compare revision rates and adverse radiographic observations at ⩾ 2 years of various uncemented humeral stem designs.We performed an electronic PubMed search for studies on uncemented primary TSA that reported one or more of the following observations at ⩾ 2 years for distinct stem designs: stem revision; subsidence; stress shielding; radiolucent lines; and humeral loosening.
