Scapholunate ligament reconstruction using an acellular dermal matrix: a mechanical study.

Purpose: Numerous surgical techniques have been described for the treatment of chronic scapholunate ligament instability. We hypothesized that scapholunate ligament reconstruction using an acellular dermal matrix was biomechanically comparable to previously described surgical reconstructions.

Methods: The scaphoid and lunate with the entire scapholunate ligament were harvested from 15 cadaveric specimens.

Surgical management of posttraumatic elbow arthrofibrosis.

Background: Functional loss of motion is a frequent complication after elbow trauma. The purpose of this study was to determine the effectiveness of open elbow release in restoring functional elbow motion.

Methods: A retrospective chart review of 177 adult patients who underwent open elbow release at our institution by the senior surgeon (D.

Total elbow allografts with collateral ligament reconstruction for posttraumatic elbow injuries.

Background: The use of total osteoarticular elbow allografts as a salvage procedure for reconstruction of posttraumatic elbow periarticular defects and bone loss has been previously described. Although the procedure restores bone stock and provides a painless functional joint, it is associated with multiple complications, including infection, nonunion, and instability.

Methods: We report a consecutive series of eight patients with posttraumatic elbow injuries and extensive bone loss treated with massive osteoarticular elbow allografts augmented by collateral ligament reconstruction using hamstring allograft.

Skeletally mature patients with bilateral distal radius fractures have more associated injuries.

Bilateral distal radius fractures are rare injuries and only a handful of case reports exist. Understanding the demographic variables and associated injuries in patients with these fractures may improve awareness and treatment of concomitant injuries. We determined the differences in mode of trauma and associated injuries between skeletally mature and skeletally immature patients with bilateral distal radius fractures.

Biomechanical and anatomical effects of an external rotational torque applied to the knee: a cadaveric study.

Background: External rotational torque is one of the mechanisms that may occur during a pivoting or twisting injury to the knee.

Hypothesis: Simulated external rotational injury by applying external rotational torque will increase knee laxity and cause soft tissue damage to the knee.

Study Design: Controlled laboratory study.
