With an expanding application of magnetic resonance imaging in acute musculoskeletal injury, an increasing number of occult traumatic lesions of bone are being identified. The authors describe the entity of fracture without radiographic abnormality, which as the name suggests is a bony injury not apparent on plain radiographs. The clinical significance and(More)
One hundred ten cases of the transient neurological phenomenon, cervical cord neurapraxia (CCN), are presented. The authors established a classification system for CCN, developed a new computerized measurement technique for magnetic resonance (MR) imaging, investigated the relationship of the cervical cord to the canal, and analyzed clinical, x-ray, and MR(More)
Few reports address the reconstructive challenge of total knee arthroplasty after a surgically fused or ankylosed knee. The long term results and complications of a large series of patients who have had their ankylosed or arthrodesed knee converted to a total knee replacement were evaluated. Thirty-seven knees (35 patients, 28 female and 7 male) without any(More)
In addition to consultation with an experienced hematologist, the following are recommendations regarding compartment syndrome in a patient with an inherited bleeding disorder. Von Willebrand's Disease. Humate-P (rich in von Willebrand factor) is the replacement therapy of choice for surgical procedures in patients with von Willebrand's disease. In general,(More)
Three- and four-part fractures are the most severe injuries in the spectrum of fractures of the proximal humerus. Despite the shortcomings of the currently available imaging techniques, fracture displacement remains an important principle in guiding management. As a result, increasing emphasis has been placed on the use of Neer's criteria in intraoperative(More)
We evaluated 55 knees in 51 patients after Elmslie-Trillat-Maquet procedures. The procedure involves medialization of the tibial tubercle on a distal pedicle and elevating the tibial tubercle anteriorly 10 mm with a local bone graft. At a mean followup of 74.2 months (range 13 to 196), all patients completed postoperative surveys and 38 underwent(More)
OBJECTIVE Treatment of flexor tendon lacerations of the finger partly depends on the degree of injury, which is difficult to determine clinically. We used a cadaver model to investigate the potential of MR imaging in evaluating these injuries. MATERIALS AND METHODS A scalpel was drawn transversely across the volar surface of four cadaver hands, producing(More)
A case of medial subtalar dislocation associated with fracture of the posterior process of the talus is described. Although this injury pattern is uncommon, it is important to recognize the associated fracture, as it involves a weightbearing articular surface. In this case, the flexor hallucis longus also prevented anatomic closed reduction necessitating(More)
Failure of surgical management of fractures of the base of the fifth metatarsal distal to the tuberosity is uncommon. Only one such failure has been reported in the literature to date. The purpose of this article is to present the clinical course of 11 patients with failure of surgically managed jones fractures reviewed by the senior author (J.S.T.).(More)
Reconstructive options for glenohumeral arthritis revolve around the timing and success of hemi-joint arthroplasty and total joint arthroplasty techniques. The purpose of this article is to discuss the alternative treatment options of shoulder arthritis. Specific options include arthroscopic debridement, synovectomy, capsular release, osteotomy, resection(More)
