Application of the island flap at the dorsum of the middle phalange with the pedicel of the digital proper artery / 中华整形外科杂志

<p><b>OBJECTIVE</b>To explore a method for the treatment of the skin defects at the distal phalanges of 2-5th fingers.</p><p><b>METHODS</b>The island flap at the dorsum of the middle phalange was designed with the pedicle of dorsal branches from the digital proper artery. When the flap was used to repair defect at finger pulp, the dorsal branch of the digital proper nerve in the flap was kept to be anastomosed to the digital proper nerve at the recipient finger. From Feb. 2005 to May. 2010, 54 cases with skin defects at the distal phalanges of 61 fingers were treated with the flap, including 35 defects at finger pulp and 26 defects at finger tip.</p><p><b>RESULTS</b>The maximum size of defects and flaps was 2.2 cm x 2.5 cm and 2.4 cm x 2.7 cm, respectively. 61 flaps survived completely. Blister was happened in 3 flaps 2 days after operation, which healed spontaneously without necrosis. 54 cases were followed up for 5 to 22 months (average, 11 months). The flaps had good texture and color match with normal sensation (grade S4). The 2-point discrimination distance was 6-9 mm. The interphalangeal joint had normal movement.</p><p><b>CONCLUSIONS</b>The island flap at the dorsum of the middle phalange is an ideal method for the skin defect at the distal phalange of finger.</p>

External fixation and bone grafting for collapsed and comminuted distal radius fracture / 中华创伤杂志(英文版)

<p><b>OBJECTIVE</b>To study the therapeutic effect of collapsed and comminuted distal radius fracture.</p><p><b>METHODS</b>Twenty-six patients with collapsed and comminuted distal radius fracture were hospitalized from July 1998 to June 2003. All fractures were treated by the methods of open reduction, sustained bone grafting and passing joint external fixator to restore the anatomic shape of distal radius.</p><p><b>RESULTS</b>All 26 cases were followed up, and the results showed that the fractures have been united radiographically. The joint surfaces were intact and there was no length discrepancy occurred in patient's radius. The average volar tilt was 6 to 15 degrees and the average ulnar tilt was 18 to 25 degrees. According to the Dieust criterion, 19 cases were rated as excellent and 7 as good.</p><p><b>CONCLUSIONS</b>The method that applying passing joint external fixator and bone grafting for the treatment of collapsed and comminuted distal radius fracture could maintain the stability of fracture and restore the length of radius and the intact of joint surface.</p>
