Shoulder Arthritis in the young adult arthroscopy to arthroplasty
Journal of Bone and Joint Surgery American Volume, 2006Co-Authors: John W Sperling, Scott P Steinmann, Frank A Cordasco, Ross D Henshaw, David A Coons, Wayne Z BurkheadAbstract:: Young adult patients with Shoulder Arthritis present challenging treatment decisions for the orthopaedic surgeon. Patients treated with Shoulder arthroplasty have the youngest average age of all patients who undergo joint arthroplasty. However, in the young, active patient or in those without advanced disease, joint arthroplasty may not be appropriate. Arthroscopic treatment or interposition arthroplasty may provide symptomatic relief without radically compromising future procedures.

economic decision model suggests total Shoulder arthroplasty is superior to hemiarthroplasty in young patients with end stage Shoulder Arthritis
Clinical Orthopaedics and Related Research, 2016Co-Authors: Suneel B Bhat, Mark D Lazarus, Charles L Getz, Gerald R Williams, Surena NamdariAbstract:Background Young patients with severe glenohumeral Arthritis pose a challenging management problem for Shoulder surgeons. Two controversial treatment options are total Shoulder arthroplasty (TSA) and hemiarthroplasty. This study aims to characterize costs, as expressed by reimbursements for episodes of acute care, and outcomes associated with each treatment.

Bone preserving technique for reverse arthroplasty: The preferred management option for osteoArthritis with glenoid bone loss in patients 70 and older
Seminars in Arthroplasty, 2018Co-Authors: Thomas R. Duquin, John W SperlingAbstract:Abstract Elderly patients with Shoulder Arthritis and glenoid bone loss represent a challenging patient population. Surgical treatment options include hemiarthroplasty, anatomic total Shoulder arthroplasty (TSA) with bone grafting or augmentation, and reverse total Shoulder arthroplasty (RSA). The RSA has multiple advantages compared to anatomic TSA, particularly in an older patient population with glenoid bone loss. RSA with an augmented glenoid baseplate is ideal for the treatment of patients who have glenoid bone loss. The augmented base plate has many advantages including bone preservation, longer central and peripheral screws, ability to dial the augment to match the region of bone deficiency, and lateralization to improve tensioning on the deltoid and rotator cuff. Additionally, a bone preserving RSA is possible with an augmented glenoid baseplate in patients with no glenoid bone loss.

MODERATE OA IN PATIENTS
Journal of Bone and Joint Surgery-british Volume, 2016Co-Authors: John W SperlingAbstract:There are a variety of potential causes of Shoulder Arthritis in young patients including osteoArthritis, inflammatory Arthritis, post-traumatic Arthritis, and avascular necrosis. However, the primary etiology in my practice is related to complications of instability surgery or labral repair: thermal or anchor/suture related chondrolysis. The outcomes of arthroscopic debridement have been disappointing in patients with Shoulder Arthritis with worse results with increasing severity of articular cartilage changes. Among all joint arthroplasty procedures, patients who undergo Shoulder arthroplasty have the youngest average age. Results of hemiarthroplasty (HA) have been approximately 75% to 80% compared to 90% with total Shoulder arthroplasty (TSA). The largest series in the literature on Shoulder arthroplasty in young patients is Schoch et al. They reviewed the results of 56 hemiarthroplasties and 19 TSA performed in patients less than 50 years old with a minimum 20-year follow-up or follow-up until reoperation. Both HA and TSA resulted in significant improvements in pain scores (p

Shoulder Arthritis secondary to rotator cuff tear a reproducible murine model and histopathologic scoring system
Journal of Orthopaedic Research, 2017Co-Authors: Alissa Zingman, Hiayan Li, Leigh Sundem, Becca Dehority, Michael B Geary, Theron Fussel, Robert A Mooney, Michael J Zuscik, John C ElfarAbstract:: Untreated rotator cuff tears can progress to a distinct form of Shoulder Arthritis, and the mechanism of this progression is poorly understood. Biomechanical, molecular and genetic factors may be at play, and a reliable animal model is needed to enable further research. The purpose of this study was to create a reproducible model of posttraumatic Shoulder Arthritis in the mouse, and to develop a scoring system for this model to enable future research on interventions, the role of various gene products, and the development of therapies to alter the natural course of the disease. Forty-five mice underwent operative ligation of the rotator cuff tendons and were followed for 45 weeks following surgery, with free cage activity post-operatively. Mice were sacrificed at various intervals from 2 to 45 weeks post-injury and histopathologic scoring was developed and tested by blinded reviewers using both quantitative computational analysis of coronal sections of the Shoulder joint and semi-quantitative grading. The scoring system revealed a progressive, time-dependent set of tissue changes in the Shoulder joint with features similar to human cuff tear arthropathy including acetabularization of the acromion and femoralization of the humeral head. This model establishes that osteoArthritis of the Shoulder is distinct from osteoArthritis of the knee or hip, with different stages of degeneration and unique histopathologic features. Using the novel grading procedure and quantitative assessments presented here, future research using this model will enable investigators to test established and novel therapies and evaluate the role of inflammatory factors and gene products in Shoulder Arthritis. This study provides a reproducible mouse model of Shoulder Arthritis following isolated injury to the rotator cuff which elucidates characteristics of cuff tear arthropathy and provides a scoring system and venue for future research. © 2016 Orthopaedic Research Society.
