PURPOSE: Large rotator cuff tears present a challenge to orthopaedic surgeons. Because tissue may be insufficient or of inadequate quality to undergo repair, a variety of materials have been used as adjuncts. Human dermal tissue may be processed to render it acellular, and thus less immunogenic, but with the extracellular matrix left intact, creating a collagen scaffold with favorable characteristics. Because of these traits, use in rotator cuff repair was proposed.

METHODS: A canine ...

PURPOSE: Percutaneous release of the A1 pulley has been used for treatment of trigger fingers with success. However, lack of direct visualization raises concerns about the completeness of the release and about potential injury to the tendons or neurovascular structures. The purpose of this study was to assess the efficacy and safety of percutaneous release of the A1 pulley in a cadaveric model using a commonly available instrument, a #15 scalpel blade.

METHODS: Fourteen fresh frozen ...

BACKGROUND: This study investigated whether axillary nerve (AN) distance to the inferior border of the humeral head and inferior glenoid would change while placing the glenohumeral joint in different degrees of external rotation and abduction.

METHODS: A standard deltopectoral approach was performed on 10 fresh-frozen cadaveric specimens. The distance between AN and the inferior border of the humeral head and inferior glenoid while placing the shoulder in 0°, 45°, and 90° of external ...

Osteochondritis dissecans (OCD) of the humeral capitellum most commonly affects young athletes engaged in sports that repetitively stress the elbow. It is characterized by localized injury of subchondral bone of the humeral capitellum. To determine the best treatment option for OCD in young athletes, it is important to differentiate between stable and unstable OCD lesions. Stable lesions can be treated with rest, whereas unstable lesions, as well stable lesions that do not respond to ...

First carpometacarpal joint arthritis is a common condition encountered by hand surgeons. Traditionally, surgical approaches have included arthrodesis, trapeziectomy or reconstructive arthroplasty techniques. Previously, we described a technique for arthroscopic debridement and interposition arthroplasty of the first carpometacarpal joint. Patients with Eaton stages II and III symptomatic first carpometacarpal joint arthritis recalcitrant to >6 months of non-operative therapy underwent ...

Primary osteoarthritis of the elbow involves formation of bony spurs, loose bodies, and capsular contracture. This article presents the results of an arthroscopic technique for treatment of elbow arthritis in a series of patients. A retrospective chart review identified 41 patients with primary osteoarthritis in 42 elbows who underwent arthroscopic osteophyte resection and capsulectomy and who had more than 2 years of follow-up. Preoperative motion, pain, and Mayo Elbow Performance Index ...

The Essex-Lopresti lesion, or radioulnar longitudinal dissociation, results from an axial load to the forearm with injury to the radial head and disruption of the interosseous membrane and the distal radioulnar joint. Unfortunately, an appreciation of the true extent of injury is not always realized in the acute setting, and patients present later with persistent or new reports of forearm discomfort and wrist and elbow pain. Reconstruction of the central band of the interosseous membrane ...

A series of 103 acute fractures of the coronoid process of the ulna in 101 patients was reviewed to determine their frequency. The Regan-Morrey classification, treatment, associated injuries, course and outcomes were evaluated. Of the 103 fractures, 34 were type IA, 17 type IB, ten type IIA, 19 type IIB, ten type IIIA and 13 type IIIB. A total of 44 type-I fractures (86%) were treated conservatively, while 22 type-II (76%) and all type-III fractures were managed by operation. At ...

Because little information is currently available on the epidemiology of shoulder arthroplasty, this study was designed to evaluate the characteristics of patients undergoing this procedure and changes in practice patterns. Residents of Olmsted County, Minnesota, who underwent shoulder arthroplasty between 1976 and 2000 were identified (98 residents, 112 procedures). A relatively lower initial rate of shoulder arthroplasty was followed by a statistically significant steady increase (P < ...

PURPOSE: To compare outcomes of treatment for scapholunate instability between acute (< 6 wk from injury) and chronic (> 6 wk) injuries, between complete and partial tears, and among surgical techniques; identify risk factors for surgical failure; and compare ligament reconstruction with repair with or without capsulodesis in the chronic period.

METHODS: We performed a retrospective chart review of 82 primary scapholunate interosseous ligament surgeries, with median follow-up of 150 ...

BACKGROUND: Scaphoid fractures are commonly seen in orthopedic practice. An organized and thoughtful approach to diagnosis and treatment can facilitate good outcomes. However, despite optimal treatment, complications may ensue. In the setting of nonunion or an avascular proximal pole, vascularized bone grafting may be needed.

METHODS AND RESULTS: In this article we review the literature regarding these injuries and describe an approach to diagnosis, treatment, and management of scaphoid ...

Most studies on shoulder arthroplasty include a diverse group of patients presenting to a tertiary care center. Little information is available regarding outcomes in a community setting. We reviewed 98 residents (110 shoulders) of Olmsted County, Minnesota who had shoulder arthroplasties from 1976 to 2000. There were 65 total shoulder arthroplasties and 45 humeral head replacements. The most common indications were osteoarthritis for total shoulder arthroplasties (48/65) and acute ...

INTRODUCTION: Hand therapists selectively strengthen the first dorsal interosseus (FDI) to stabilize arthritic joints yet the role of the FDI has not yet been radiographically validated.

PURPOSE: To determine if FDI contraction reduces radial subluxation (RS) of the thumb metacarpal (MC).

METHODS: Fluoroscopy was used to obtain true anterior-posterior radiographs of non-arthritic CMC joints: 1) at rest, 2) while stressed and 3) while stressed with maximal FDI contraction. Maximal FDI ...

Forearm longitudinal instability results from an axial load to the forearm with fracture or dislocation of the radial head and disruption of the interosseous membrane and that of the distal radioulnar joint. Patients may present in the acute or chronic setting with radioulnar instability as manifested by persistent or new forearm discomfort and wrist and elbow pain. Reconstruction of the interosseous membrane has been described to restore longitudinal forearm stability. We describe ...

HYPOTHESIS/BACKGROUND: Coronoid fractures have traditionally been described by the Regan-Morrey classification system, based upon lateral plain film radiographs. However, use of computer tomography (CT) scans to determine fracture morphology, define associated injuries, and make treatment plans is now commonplace. In addition, it is increasingly recognized that classification systems based upon plain film imaging studies may not be adequate to describe complex fracture patterns. The ...
