Advances in the Repair of Palmer type IB TFCC Injuries With Wrist Arthroscopy.

The triangular fibrocartilage complex (TFCC) is essential for maintaining wrist stability. Injury-caused pain is the primary cause of ulnar wrist pain. The TFCC injury refractory to conservative treatment requires further surgical treatment, and because Palmer type IB tears belong to peripheral injuries due to their proximity to the blood supply area, arthroscopic suture repair has become the preferred surgical method for TFCC injury repair, exhibiting strong healing ability.

Pseudoaneurysm of the brachial artery in an infant due to vaccination: a case report.

Background: Pseudoaneurysm is a known complication of penetrating arterial injuries such as catheterization, gunshot wounds, and open fractures. Vaccination is an effective method for preventing multiple, serious, infectious diseases in children. Common adverse reactions related to vaccination include fever, swelling, redness, and pain.

[Short-term effectiveness of Swanson artificial joint replacement in treating posttraumatic metacarpophalangeal joint stiffness].

Objective: To investigate the short-term effectiveness of Swanson artificial joint replacement in treating post-traumatic metacarpophalangeal joint stiffness.

Methods: Between August 2007 and May 2010, 11 cases (13 fingers) of metacarpophalangeal joint stiffness with soft tissue defects underwent Swanson artificial joint replacement. There were 7 males (9 fingers) and 4 females (4 fingers), aged 43 to 65 years with an average of 49 years.

[The reverse forearm flap pedicled with the ulnar branch of the ulnar artery].

Objective: To introduce a new flap for the repair of soft tissue defects in the hand.

Methods: The distally pedicled ulnar flap is based on the ascending branch of the upper-wrist cutaneous branch of the ulnar artery. The retrograde flow is ensured by the dorsal carpal arch via the descending branch.
