INTRODUCTION: Revision shoulder arthroplasty presents many unique and complex challenges when glenoid bone loss is involved. A distorted and medialized anatomy prevents the proper mechanics of the reverse prosthesis with regard to deltoid tension and ultimate function. This paper highlights one surgeon's experience using structural allograft for glenoid bone loss. PATIENTS AND METHODS: In all, 20 patients for a total of 24 surgeries with a medialized glenoid and/or substantial glenoid bone loss of grade IIB or higher were evaluated in this retrospective study...

BACKGROUND: Both anatomic (TSA) and reverse total shoulder arthroplasty (RTSA) are common interventions for glenohumeral arthrosis, with the goal of relieving pain and restoring mobility. Understanding shoulder arthroplasty motion and frequency is of interest in evaluating effectiveness and in predicting bearing wear for implant development and optimization. The purpose of this study was to measure and compare the total daily shoulder motion of patients after TSA and RTSA. METHODS: Thirty-six human subjects who had undergone shoulder arthroplasty wore a custom instrumented garment that tracked upper extremity motion for the waking hours of 1 day...

The purpose of this study was to compare reverse total shoulder arthroplasty (RTSA) outcomes in normal weight, overweight, and obese patients. A RTSA outcomes registry was reviewed for rotator cuff-deficient patients with a minimum 2-year follow-up. Fractures, rheumatoid arthritis, and revisions were excluded. Based on World Health Organization body mass index (BMI) classification, there were 29 normal weight, 50 overweight, and 51 obese patients. All groups demonstrated significant improvements from preoperative to most recent follow-up in function scores, pain, and forward elevation...

INTRODUCTION: The use of reverse shoulder arthroplasty (RSA) has increased dramatically over the last two decades, with many surgeons now indicating RSA for the acute management of displaced proximal humerus fractures (PHF) in the elderly. RSA relies on adequate deltoid muscle function to obtain a good outcome, yet no literature to date exists which discusses preoperative assessment of deltoid structure prior to RSA. The purpose of this study was to assess for preoperative fatty deltoid-degeneration in patients with displaced PHF...

BACKGROUND: Proximal humeral bone loss in shoulder arthroplasty is a complex problem with a heterogeneous presentation. Different etiologies may contribute to varying degrees of severity in bone loss that dictate different treatment approaches. OBJECTIVES: The purpose of this is article is to describe our technique for treatment of proximal humeral bone loss with proximal humeral allograft prosthetic composites (APC) and identify factors that may predict when larger allografts may be necessary...

BACKGROUND: Although recent evidence suggests that any prior shoulder surgery may cause inferior shoulder arthroplasty outcomes, there is no consensus on whether previous rotator cuff repair (RCR) is associated with inferior outcomes after reverse total shoulder arthroplasty (RTSA). PURPOSE: To retrospectively compare outcomes in patients who underwent RTSA with and without previous RCR. STUDY DESIGN: Cohort study; Level of evidence, 3. METHODS: Patients with prior RCR and those without previous shoulder surgery (control) who underwent RTSA for cuff tear arthropathy or irreparable cuff tear were retrospectively identified from a prospective database...

Cryoneurolysis entails using low temperatures to reversibly ablate nerves, with a subsequent analgesia duration measured in weeks or months. Previously, clinical applications for acute pain were limited because treatment originally required exposing the target nerve surgically. However, three developments have now made it possible to provide prolonged postoperative analgesia by cryoneurolysis: 1) new portable, hand-held cryoneurolysis devices, 2) ultrasound machine proliferation, and, 3) anesthesiologists trained in ultrasound-guided peripheral nerve block administration...

BACKGROUND: Platform shoulder arthroplasty systems may allow conversion to a reverse total shoulder arthroplasty (RTSA) without removing a well-fixed, well-positioned humeral stem. We sought to evaluate the complications associated with humeral stem exchange versus retention in patients undergoing conversion shoulder arthroplasty with a platform shoulder arthroplasty system. METHODS: PubMed, MEDLINE, CINAHL (Cumulative Index to Nursing and Allied Health Literature), and Embase were searched from database inception through October 9, 2016, for all articles comparing humeral stem retention versus exchange during conversion RTSA or that pertained to conversion RTSA with stem retention alone...

BACKGROUND: There has been serious concern regarding the longevity and durability of outcomes of reverse total shoulder arthroplasty (RTSA) in younger patients. It was the purpose of this study to analyze long-term outcomes and complications of RTSA for irreparable rotator cuff tears in patients younger than 60 years. METHODS: Twenty patients (23 shoulders) with a mean age of 57 years (range, 47 to 59 years) were evaluated at a mean of 11.7 years (range, 8 to 19 years) after RTSA...

PURPOSE OF THE REVIEW: The goal of this review is to provide a guide on surgical decision-making options for complex anterior shoulder instability using a case-based approach. RECENT FINDINGS: Arthroscopic Bankart repair is well documented for having successful outcomes in patients with isolated labral tear involvement with minimal bone loss. Latarjet is a generally accepted procedure in patients with 20-30% glenoid bone loss. When bone loss exceeds that which cannot be managed through Latarjet, a range of options exist and are highly dependent upon the extent of osseous deficiency on both the glenoid and humeral sides, surgeon experience, and patient-specific factors...

INTRODUCTION: Obesity is an epidemic nowadays and this fact conditions results in orthopaedic surgery. Very few studies evaluates if obesity is a risk factor for reverse shoulder arthroplasty. The aim of this study is to confirm if there are differences with regard to the outcomes in patients undergoing reverse shoulder arthroplasty according to their body mass index (BMI). MATERIALS AND METHODS: A total of 35 patients were enrolled in the study. Then divided into subpopulations according to their BMI and analyzed twice...

This study described surgical treatment patterns for proximal humerus fractures among elderly patients, focusing on reverse total shoulder arthroplasty (TSA), and evaluated how the type of fixation affects inpatient factors (cost, length of stay), transfusion rates, and patient disposition (home vs skilled nursing facility). With Nationwide Inpatient Sample data from 2011 to 2013, the authors identified patients 65 years and older who had proximal humerus fractures and divided them into 3 groups: (1) open reduction and internal fixation (ORIF); (2) hemiarthroplasty; and (3) reverse TSA...

INTRODUCTION: In 2014, reverse total shoulder arthroplasty was approved in Japan. We were concerned that the base plate might be incompatible with Japanese who were generally smaller than Westerners. Therefore we investigated the dimensions and morphology of the normal Japanese glenoid and compare with the normal French glenoid. MATERIALS AND METHODS: One hundred Japanese shoulders without glenoid lesions (50 men and 50 women) were investigated and compared with 100 French shoulders (50 men and 50 women)...

PURPOSE: National registries are valuable tools for understanding the results of shoulder arthroplasty across populations. These databases provide an unselected view of shoulder joint replacement within geographical areas that cannot be obtained from case series or prospective studies. They can be particularly helpful in determining which diagnoses, patients, procedures, and prostheses have higher than expected rates of revision. In an attempt to determine the generalizability of registry data, we asked, 'how similar are the patients and procedures among the different national registries?' METHODS: We analyzed national shoulder arthroplasty registries and databases accessed via Internet portals and through a PubMed literature search...

Periprosthetic fractures is a severe complication after joint replacement. The rapidly increase of reverse shoulder arthroplasty surgeries, periprosthetic humeral fractures, which are described as rare, may increase in the near future. We report the case of displaced humeral fracture bellow the stem of reverse shoulder prosthesis. The patient was an 85-year-old woman who had a total shoulder replacement 6 years previously. The surgical solution consisted of plate osteossynthesis and cerclage. This report describes an unprecedented case in Brazilian literature; and gives an overview of the existing literature including this injury classification...

We report the case of a 70-year-old male with Parkinson's disease (PD) and recurrent traumatic left shoulder dislocations. This case is rare because (1) he had a massive irreparable rotator cuff tear and end-stage arthritis (i.e., rotator cuff-tear arthropathy) of the same shoulder and (2) his shoulder was ultimately reconstructed with a reverse total shoulder arthroplasty (RTSA). His first dislocation occurred after a fall. Recurrent shoulder dislocations occurred despite successful closed reduction and physical therapy...

BACKGROUND: Large glenoid bone defects in the setting of glenohumeral arthritis can present a challenge to the shoulder arthroplasty surgeon. The results of large structural autografting at the time of reverse total shoulder arthroplasty (RTSA) are relatively unknown. METHODS: This retrospective case series describes the clinical and radiographic results of large structural autografting from the humeral head to the glenoid during primary RTSA. RESULTS: Of 17 patients who met inclusion criteria, 14 (82% follow-up) were evaluated postoperatively at a mean of 2...

BACKGROUND: There is an increasing body of literature suggesting that the use of patient-specific instrumentation (PSI) in total shoulder arthroplasty (TSA) results in improved positioning of the glenoid component. The aim of this in vivo study was to assess the accuracy of PSI of the glenoid component in TSA in a consecutive series at a single center. METHODS: Eleven consecutive TSAs (7 TSAs and 4 reverse TSAs) were performed using custom-made patient-specific positioning guides for the glenoid component...
