OBJECTIVE: To investigate the clinical effect of skin flaps repairing severe thermopressure injury of hand. METHODS: From January 1989 to December 1998, 112 patients with severe thermopressure injury of hand were repaired by various skin flaps transfer, the size of skin flaps was 6 cm x 8 cm to 12 cm x 18 cm. Postoperative patients were treated by combined rehabilitation in early stage. RESULTS: All the flaps were survived with satisfactory effect. Sixty-six patients were followed up 6 to 12 months, skin flaps all showed better colour and texture, and function of the hand was satisfactory. CONCLUSION: Different skin flaps are adopted to repair severe thermopressure injury of the hand according to different skin defects of the hand, combined early rehabilitation treatment, to achieve good recovery of function and appearance of the hand to the greatest extent.
OBJECTIVE: To explore the importance of the posterior and lateral arterial network of elbow in the application of the super-regional and mutual-pedicled axial flap. METHODS: Twenty-seven upper extremities of adult cadavers were prepared as casts of Acrylomintril Batradiene Styrene(ABS) resin and corroded in a b solution of NaOH according to natural layers of human tissue. The source, site and structure of the posterior and lateral arterial network of elbow were observed, the number and total sectional area of anastomosing branches crossing the line between two humeral epicondyles were measured and compared with the medial and anterior region. RESULTS: There are 8.64 +/- 2.74(36.42%) and 8.30 +/- 1.19(35.0%) anastomosing branches crossing the posterior and lateral regions, and total section areas are (0.48 +/- 0.11) mm2 and (0.37 +/- 0.03) mm2 respectively. So there is very rich arterial network around the elbow. CONCLUSION: The enough number of anastomosing branches and their section areas of the posterior and lateral region of the elbow make it possible to connect super-regional and mutual-pedicled axial flaps crossing the elbow.
