Chronic massive rotator cuff tears are challenging to repair completely because of the development of tendon retraction with inelasticity, muscle atrophy and fatty infiltration. The objective of this study was to investigate the clinical outcome and MRI findings after arthroscopic superior capsule reconstruction (ASCR) for symptomatic irreparable rotator cuff tears. From 2011 to 2013, 12 shoulders in 12 consecutive patients (mean, 70.8 years) with irreparable massive rotator cuff tears underwent ASCR using fascia lata. We used suture anchors to attach the graft medially to the glenoid superior tubercle and laterally to the greater tuberosity as same technique by Mihata et al. We added side-to-side sutures between the graft and infraspinatus tendon and between the graft and residual anterior supraspinatus/subscapularis tendon to improve force coupling. Physical examination, clinical rating system, and magnetic resonance imaging (MRI) were performed before surgery; at 6 and 12 months after surgery; and 6 months thereafter. Average follow-up was 19.1 months (12 to 28 months) after surgery. We assessed patients preoperatively by using the scoring systems of the shoulder index of the American Shoulder and Elbow Surgeons (ASES), the Japanese Orthopaedic Association, and the University of California, Los Angeles.Purpose
Methods
Surgical treatment is standard for advanced osteochondritis dissecans (OCD) of the humeral capitellum. When cartilage is seen to be separated or completely detached, this fragment fixation is not usually applied. There have been reports of cases in which advanced OCD of the humeral capitellum progressed to osteoarthritis (Fig), particularly in cases which involved the lateral wall. In these cases, every attempt should be made to reconstruct the lateral wall to avoid osteoarthritis. In this study, we followed up cases with rib osteochondral autograft transplantation technique. Subjects were 20 cases who were followed up until after they started pitching. The mean age was 13.8 years old and the mean observation period was 2 years and 6 months (from 7 months to 6 year 3 months). Kocher's approach was used to give a good access to the aspect of the radiohumeral joint. The majority of cases suffered from extensive OCD of the elbow. Detached fragment was removed (Fig. 2a) and graft from 5th or 6th rib with screw fixation was performed on 12 patients and 8 received fixation with no material (Fig. 2b). Follow-up assessment included the range of motion, start time of playing catch and throwing a ball with full power, sports activity, evaluation of radiography, a subjective (including Pain, Swelling, Locking/Catching and Sport activity) and objective (Flexion contracture, Pronation/Supination and sagittal arc of motion) modified elbow rating system by Timmeman et al. We also investigated the details of the arthroscopy observations and the 2nd arthroscopy findings for 4 cases.Objectives
Methods
The treatment of 3- or 4-part proximal humeral fractures in elderly can be carried out with hemiarthroplasty. Also hemiarthroplasty has performed for failed osteosynthesis or conservative treatment in Japan. However the secondary hemiarthroplasty has poor clinical outcome. The aim of this study was to compare the clinical outcomes of primary and secondary hemiarthroplasty for proximal humeral fractures. Between March 2004 and January 2013, twenty-four shoulders in 23 patients (22 females, 1 male) with proximal humeral fractures and fracture dislocations underwent hemiarthroplasty. The mean age was 75.6 years and the average follow-up period was 25.6 months (range 3 to 108 months). Eighteen shoulders in 17 patients were treated primary with hemiarthroplasty (primary group). Six shoulders in 6 patients were treated with hemiarthroplasty after other treatments had failed (secondary group). All patients were evaluated with the Japan Orthopaedic Association shoulder scoring system (JOA score) and range of motion.Introduction:
