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...

We previously evaluated 94 patients (96 shoulders) who underwent reverse shoulder arthroplasty using a central compressive screw with 5.0-mm peripheral locking screws for baseplate fixation and a center of rotation lateral to the glenoid as treatment for end-stage rotator cuff deficiency. The purpose of this study was to report updated results at a minimum follow-up of 10 years. Forty patients (42 shoulders) were available for clinical follow-up. In the patients available for study, implant survivorship, with the end point being revision for any reason, was 90...

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...

BACKGROUND: Wheelchair-dependent patients rely on their upper extremities for mobility and transfers. This entails the heavy use of upper extremities as weight-bearing joints, leading to shoulder overuse with increased prevalence of rotator cuff-related disorders, and ultimately to challenging cases for shoulder surgeons when a joint replacement is needed. OBJECTIVE: To report the outcomes of reverse shoulder arthroplasty (RSA) in wheelchair-dependent patients with arthritis and rotator cuff tears...

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...

In a systematic review, we critically examined and synthesized the results of individual studies on reverse shoulder arthroplasty (RSA) with latissimus dorsi tendon transfer. Two electronic databases were searched. For each included study, 2 reviewers evaluated the quality of its methods and retrieved data. In cases in which outcomes data were similar between studies, data were pooled using frequency-weighted (FW) mean values to generate summary outcomes. Seven studies met the inclusion and exclusion criteria, and 133 patient cases were reviewed...

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 AND AIM OF THE WORK: Cuff tear arthropathy (CTA) is a well-defined  degenerative pathology  of the shoulder. When conservative treatments are unable to permit a good quality of life, the reverse shoulder arthroplasty (RSA) can guarantee a good restitution of range of motion, function and strength of the shoulder without pain. In this paper we show our clinical, functional and radiological outcomes, as well as complications of RSA in patients with CTA. METHODS: We analyzed 31 patients who underwent to reverse shoulder replacement with Modular Shoulder System (SMR, Systema Multiplana Randelli; Lima-LTO, San Daniele del Friuli, Italy) reverse shoulder system, between August 2010-July 2014...

TECHNIQUE: The treatment of bone defects in primary shoulder arthroplasty has evolved due to more detailed diagnostic tools, 3D planning and expanded indications for reverse shoulder arthroplasty. Glenoid bone defects combined with chronic posterior subluxation of the humeral head are gradually being treated by glenoid reconstruction and reverse implants even if the rotator cuff is still intact. The treatment of advanced bone loss due to glenoid loosening has been facilitated by bone augmentation using a cementless fixation as proposed by Norris...

BACKGROUND: Anatomic shoulder arthroplasty in osteoarthritis with biconcave glenoid wear results in decreased functional results and a higher rate of early glenoid loosening. AIM: The aim of the data analysis of the German shoulder arthroplasty register was to clarify whether reverse shoulder arthroplasty can provide better functional results and a lower complication rate than anatomic arthroplasty in osteoarthritis with biconcave glenoid wear. METHODS: The analysis included 1052 completely documented primary implanted arthroplasties with a minimum follow-up of 2 years...

BACKGROUND: Failure rates after rotator cuff repair remain high in patients with massive tears. Although superior translation of the humeral head has been used to assess the severity of rotator cuff tears, the relevance of anterior migration of the humeral head to clinical outcomes has not been established. The purpose of this study was to investigate the potential role of the T-scale, a measure of the anterolateral translation of the humeral head, as a prognostic factor for rotator cuff repair...

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...

Pseudoparalysis has been previously described as the inability to elevate the arm over 90° in the setting of a rotator cuff tear. Controversy exists regarding the optimal treatment for patients with a pseudoparalytic shoulder with a rotator cuff tear with options including rotator cuff repair and reverse shoulder arthroplasty. Recent literature suggests that pseudoparalysis can reliably be corrected with a rotator cuff repair and is more cost effective than reverse shoulder arthroplasty. We believe that the arbitrary cutoff of 90° is too generous and leads to confusion...

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...
