Background: Ruptures of the tendons rotator cuff lead to profound and possibly irreversible changes in structure physiological properties muscles. Muscle atrophy fatty infiltration are important prognostic factors that affect natural history outcome treatment. The purpose this study was examine amount muscle an animal model determine whether repair a long-standing tendon tear can reverse these changes. Methods: infraspinatus six sheep released encased silicone tube prevent spontaneous...

The purpose of this study was to evaluate the role radial head and coronoid process as posterolateral rotatory stabilizers elbow determine stabilizing effect replacement reconstruction.The displacement ulna measured after application a valgus supinating torque (1). in seven intact elbows, (2). excision, (3). sequential resection process, (4). subsequent insertion each two different types metal prostheses (a rigid implant bipolar with floating cup), (5). reconstruction techniques same...

Forty-one consecutive patients were managed for post-traumatic osteoarthrosis or dysfunction of the elbow with use a non-customized semiconstrained Coonrad-Morrey total prosthesis. The average age at time operation was fifty-seven years (range, thirty-two to eighty-two years). followed an five and eight months two twelve Radiographs made least postoperatively (average, one month; range, years) thirty-nine forty-one patients. According Mayo performance score, sixteen (39 per cent) had...

Retears after rotator cuff repairs occur relatively frequently and may compromise the functional result. The goal of this study was to analyze mechanical properties following arthroscopic techniques for repair evaluate possible alternative techniques.In first part, five different bone anchors (the Revo screw; Mitek Rotator Cuff anchor, 5.0-mm Statak, PANALOK RC absorbable Bio-Statak) were tested in vitro under cyclic loading on pairs cadaveric shoulders. Then types tendon suturing...

To determine the prevalence of articular cartilage lesions in patients with subacromial impingement syndrome and to assess diagnostic effectiveness magnetic resonance (MR) arthrography detecting such abnormalities.MR arthrographic images obtained 52 consecutive (mean age, 45.8 years; age range, 17-73 26 male female patients) were retrospectively evaluated for glenohumeral lesions. Two experienced musculoskeletal radiologists who blinded arthroscopy report independently analyzed cartilage....

Management of posttraumatic radiocapitellar and/or proximal radioulnar joint dysfunction and pain is a challenging problem, often with more than one pathological feature, to date there are no consistently reliable solutions. The unreliability prosthetic replacement prompted us develop an anconeus arthroplasty wherein the muscle rotated into joint.Three interposition options were assessed in our laboratory employed clinically: at (Type I), joints II), (wrap) III). clinical outcomes fourteen...

Background Conventional posterior interosseous flap has the disadvantage of partial or even complete necrosis when there is anatomical variation contusion around its distal pedicle. To make it a more reliable flap, three types auxiliary procedures were designed. Methods (1) When congestion after inset distally hased an additional venous anastomosis was carried out. (2) so that based could not be raised without compromising nerve branches, found pedicle, changed into free flap. This design...

In retrospectively analyzing 35 consecutive patients with chronic spondylotic radiculopathy treated by nerve root decompression, interbody fusion (Robinson technique), and plating, we studied the perioperative complication rate as well long-term clinical radiologic outcomes of an additional plate fixation in degenerative cervical disorders. After average 54 months (range 24–102 months), all cases were reviewed for purpose this study. There no or postoperative complications related to...

The macroscopic arterial vascularization of the extensor carpi radialis brevis tendon was investigated in 12 elbows from cadavers to provide fundamental anatomic information this which has been associated with lateral epicondylitis. blood supply highly consistent. radial recurrent artery vascularized entire proximal through direct branches medial and border forming a network small vessels on surface tendon. Important contributions were provided by posterior branch collateral artery, minor...
