PURPOSE: The purpose of this study was to review the average 4-year outcomes of a cohort of patients with wrist arthritis, treated by a single surgeon with a novel prosthetic hemiarthroplasty of the midcarpal joint. We hypothesized that midcarpal hemiarthroplasty would improve range of motion and grip strength of patients with wrist arthritis, with a complication profile comparable with that of alternative solutions for wrist arthritis. METHODS: We reviewed a series of 20 patients treated with a midcarpal hemiarthroplasty at an average of 4 years following surgery...

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...

BACKGROUND: Glenoid component loosening remains a significant issue after anatomic shoulder arthroplasty. Pegged glenoid components have shown better lucency rates than keeled components in the short term; however, midterm to long-term results have not fully been determined. We previously reported early outcomes of the current randomized controlled group of patients, with higher glenoid lucency rates in those with a keeled glenoid. The purpose of this study was to evaluate the radiographic and clinical outcomes of these components at minimum 5-year follow-up...

BACKGROUND: The PERFORM™ pegged glenoid system has been used for shoulder arthroplasty since 2012. This system offers multiple backside curvatures per size to better match variable patient anatomy. As a result, less reaming is required and subchondral bone is preserved-a critical factor in preventing glenoid migration and loosening, thus enhancing implant longevity. PURPOSE: The purpose of this study was to analyze all radiographic modifications around this new glenoid implant...

INTRODUCTION: Complications after internal fixation of proximal humerus fracture are common and may require surgical revision. Reverse total shoulder arthroplasty (RTSA) is frequently performed in such cases. The aim of the present study was to evaluate the functional results and complications after RTSA for the treatment of type I fracture sequelae after internal fixation of proximal humerus fractures. MATERIALS AND METHODS: 26 patients (18 female, 8 male) underwent surgical revision of type I fracture sequelae of the proximal humerus after locking plate (n = 22) or intramedullary nail (n = 4) fixation...

INTRODUCTION: Diabetes has been associated with negative outcomes following orthopaedic surgery. While previous studies have reported on diabetes-associated complications in shoulder arthroplasty, those cohorts were heterogeneous in terms of patient population, nature of elective surgery, and arthroplasty type. Given that the number of elective total shoulder arthroplasties (TSAs) performed has grown substantially in volume and is predicted to rise even further, it is important to recognize the role that diabetes may play in developing in-hospital complications within a more homogenous sample of patients undergoing elective TSA...

Reverse Shoulder Arthroplasty (RSA) has gained popularity over the recent years, but impingement concerns are still present. Surgeons aim to correct pre-operative glenoid deformities to reduce impingement but it can be challenging without assistance like patient specific guides. However, it is unclear how accurate glenoid correction affects the impingement. The main objective of this study was to determine whether accurate glenoid correction to neutral version and tilt can reduce the risk of impingement. Two types of virtual surgeries were performed on 22 pre-operative arthritic shoulders: i)'Interactive', the glenoid baseplate could be placed with accuracy, and ii)'Blind', surgeons placed the RSA baseplate while they could only visualize the glenoid...

BACKGROUND: Larger glenosphere diameters have been used recently to increase prosthesis stability and impingement-free range of motion in reverse total shoulder arthroplasty. The goal of this study was to evaluate the rate of polyethylene wear for 32-mm and 40-mm glenospheres. METHODS: Glenospheres (32 mm and 40 mm, n = 6/group) and conventional polyethylene humeral liners underwent a 5-million cycle (MC) wear simulation protocol. Abduction-adduction and flexion-extension motion profiles were alternated every 250,000 cycles...

BACKGROUND: The fractures of proximal humerus have a high incidence in elderly patients, especially 3- or 4-part fracture. There are 4 main treatments including nonoperation, open reduction and internal fixation(ORIF), hemiarthroplasty(HA) and reverse shoulder arthroplasty(RSA). However, which one is the optimal choice remains a controversial topic. METHODS: Through the search of three electronic databases (PubMed, Embase, and Cochrane), the randomized controlled trials of 3- or 4-part proximal humeral fracture, until the end of July 2017, which is concerned with the elderly patients, were identified...

BACKGROUND: In total hip arthroplasty (THA) surgery, hip muscle preservation is important in strengthening the stability of the hip and improving the activities of the patient. However, whether the type of femoral stem affects the recovery of the hip muscles remains unknown. The aim of this study was to compare the postoperative hip muscle recovery among femoral stem varieties after THA. METHODS: The computed tomography (CT) images of 44 patients (44 hips) who underwent THA using an anterolateral approach were reviewed...

Hemiarthroplasty implantation for proximal humerus fracture is challenging. In case of young demanding patients with functional rotator cuff, humeral head replacement is an option if open reduction internal fixation is not a viable solution. The criteria for success in terms of clinical outcomes and longevity are anatomic healing of the tuberosities and stem positioning (restoring correct height, version, and axis). The purpose of this article is to describe a technique including a new stem guide and a tuberosity anchor "lasso" system for the implantation of hemiarthroplasty in complex proximal humerus fractures...
