ABSTRACT
As to terrible triad injury of elbow joint, because of the complexity of the surrounding anatomy of the elbow joint, the limited biomechanical study, the difficult treatments, and the poor prognosis, the choice of the treatment scheme is still controversial. This article summarizes the anatomy, injury mechanism, surgical treatment and prognosis of elbow joint by retrieving a large number of references. Currently, there are various surgical treatments for triad injury of elbow joint, but due to individual differences, the clinical efficacy is mostly uncertain. In the treatment of triad injury of elbow joint, most orthopedics doctors still choose the lateral surgical approach to fix the coronary fracture, repair or replace the radial head, routinely repair the lateral collateral ligament, and not recommend to repair the medial collateral ligament, so it still remains to be discussed.
ABSTRACT
<p><b>OBJECTIVE</b>To evaluate the effect of insular pectoralis major myocutaneous flap on repair of jaw and neck tissue defect as a result of high-voltage electric burn.</p><p><b>METHODS</b>Eighteen patients with large area tissue defect in jaw and neck caused by high-voltage electric burn hospitalized from August 2001 to December 2007 were repaired with insular pectoralis major myocutaneous flap. The flaps (from 12 cm x 10 cm to 16 cm x 13 cm) was transplanted in 8 patients after early wound debridement, and in 10 patients on infected wounds.</p><p><b>RESULTS</b>All flaps survived wells except in 4 patients necrotic area (length 2-5 cm, width 1-2 cm) appeared in the distal wound edge, localized dehiscence of wound edge in 2 cases, which were healed after dressing change or secondary suturing. Patients were followed up from 6 months to 3 years, and the appearance and function were satisfactory.</p><p><b>CONCLUSIONS</b>Pectoralis major muscle island myocutaneous flap has the advantage of large tissue mass, with thin and flat muscle belly, and rich blood supply, which is suitable for repair of large deep tissue defect in jaw and neck.</p>
