BACKGROUND Female athletes have a higher incidence of anterior cruciate ligament injuries than do male athletes in similar sports. Hormones, particularly estrogen, have been indicated by some studies to be correlated with the disproportionate number of anterior cruciate ligament injuries in female athletes. HYPOTHESIS Estrogen does not affect the mechanical or material properties of primate a...

Improper diagnosis and treatment of finger injuries can cause deformity and dysfunction over time. A basic understanding of the complex anatomy of the finger and of common tendon and ligament injury mechanisms can help physicians properly diagnose and treat finger injuries. Evaluation includes a general musculoskeletal examination as well as radiography (oblique, anteroposterior, and true later...

Surgical procedures for double-bundle reconstruction of anterior cruciate ligament, which currently use semitendinous and gracilis tendon grafts, have been described in the last decade. Most of the techniques utilize twice the hardware used in single-bundle reconstructions. We report an original anterior cruciate ligament double-bundle reconstruction technique using semitendinous and gracilis t...

We treated 43 acute tears of the calcaneofibular ligament by operation in 43 patients after subtalar arthrography. There were 22 men and 21 women with a mean age of 22.3 years (14 to 61). Anteroposterior (AP), lateral and oblique views were obtained with the foot in 45 degrees of internal rotation and the ankle in the neutral position. Any communication or leakage to the ankle, tendon sheaths, ...

BACKGROUND Patellar and hamstring tendon autografts are the most frequently used graft types for anterior cruciate ligament reconstruction, but few direct comparisons of outcomes have been published. HYPOTHESIS There is no difference in outcome between the two types of reconstruction. STUDY DESIGN Prospective randomized clinical trial. METHODS After isolated anterior cruciate ligament rup...

During limb development, the interdigital mesenchyme has been proposed to play a signaling role instructing morphogenesis of different digit types, as well as undergoing programmed cell death necessary to free digits in animals not adapted for swimming or flying. We have generated a conditional, tamoxifen-dependent Cre line, Bmp2CreER, which drives highly selective recombination restricted to t...

To date, there is no consensus on the best technique to repair injured posterolateral structures of the knee. We evaluated the effects of a fibular head based isometric reconstruction of the posterolateral knee corner with a double bundle semitendinosus tendon. From February 2001 to February 2005, 18 isometric reconstructions of a chronic posterolateral corner (PLC) injury of the knee were perf...

Clear cell sarcoma (CCS, malignant melanoma of soft parts) is a rare neoplasm accounting for 1% of all soft tissue sarcomas (1). Young adults between the ages of 20 and 40 are most commonly involved (1). CCS is intimately associated with or in a tendon, ligament, or aponeurosis. Suggestive features of diagnosis best seen on MR imaging include a mass having components not only surrounding but wi...

Triceps tendon ruptures are rare injuries. Coexistence of ipsilateral ulnar collateral ligament injury is even rarer. Here, we describe an unusual combination injury to elbow of a 39-year-old male construction worker consisting of triceps tendon rupture, avulsion of elbow ulnar collateral ligament and flexor pronator muscle origin ipsilaterally. A simultaneous repair and reconstruction of all d...

Proximal junctional kyphosis is an increasingly recognized complication following long-segment posterior spinal fusion for adult spinal deformity. The authors describe a novel technique for interspinous ligament reinforcement at the proximal adjacent levels using a cadaveric semitendinosus tendon graft secured with an Ethibond No. 2 double filament (Ethicon, Somerville, New Jersey) via the Krac...
