Extensor Tendon Instability Due to Sagittal Band Injury in a Martial Arts Athlete: A Case Report.

A Taekwondo participant sustained a hand injury from punching an opponent that resulted in painful instability of the ring finger extensor digitorum communis tendon due to sagittal band damage. His symptoms resolved after reconstructive surgery on the sagittal band (SB) with stabilization of the extensor tendon over the metacarpophalangeal joint.

Thumb basal joint arthroplasty using abductor pollicis longus tendon: an average 5.5-year follow-up.

Purpose: The goal of this study was to evaluate the 4-year minimum (5.5-y average) results of trapeziectomy and ligament reconstruction using a modified Thompson technique with the abductor pollicis longus tendon for the primary treatment of advanced-stage basal joint arthritis (Eaton stages III and IV).

Methods: We evaluated 25 thumbs in 18 patients after ligament reconstruction arthroplasty for surgical treatment of advanced thumb basal joint arthritis.

New technologies for the management of major extremity wounds.

Soft tissue reconstruction for large or difficult defects, particularly of distal extremities, may be associated with a variety of problems. Crush injuries and infection are often background settings requiring use of considerable resources, time, and skilled personnel for appropriate treatment. Harvested tissue, known as a flap, is used for transferring healthy, viable tissue from one location to the area of tissue loss.

The effect of postconditioning on the muscle flap survival after ischemia-reperfusion injury in rats.

Background: Timely recognition of vascular compromise of free flaps is crucial to salvaging failing flaps due to the vulnerability of muscle tissues to ischemia. The concept of postconditioning (post-con) that has been introduced as an “after injury" strategy may be beneficial to salvage the failing muscle flaps. We aim to investigate the effect of post-con on the muscle flap survival after ischemia-reperfusion (I/R) injury in rats.

Extensor tendon reconstruction for zones II and IV using local tendon flap: a cadaver study.

Purpose: To assess the feasibility of reconstructing extensor tendon segmental defects in zones II (over the middle phalanx) and IV (over the proximal phalanx) using local tendon flaps (LTFs), explore in these 2 zones the anatomical constraints that limit the use of the LTF as regards the maximum defect that could be reconstructed, and compare this flap with distant tendon grafts (DTG) reconstruction for similar size defects.

Methods: We dissected 33 fresh-frozen cadaver extensor tendons from the fingers of 9 fresh-frozen cadaver forearms. A 0.
