Objective To discuss the clinical effect of repairing soft tissue defects in cnemis,ankle and foot with calf and sural distal fasciocutaneous flaps. Methods From August 1998 to July 2004, 34 cases of soft tissue defects in cnemis, ankles and feet were repaired with calf and sural distal fasciocutaneous flaps. There were 27 males and 7 females, aging from 17 to 61 years and the disease course was 4 hours to 8 months. The locations were metainferior segment of cnemis in 18 cases, ankle and foot in 11cases, weight loading region of calcar pedis in 5 cases. There were 13 cases chronic osteomyelitis in tibia or calcaneal bone, 8 cases of raw surface was infected, 3 cases of bone exposure.The sizes of the flap ranged from 6 cm×4 cm to 15 cm×12 cm. Results Thirty-one flaps survived except 3 cases which had partial necrosis. They were followed up from 6 months to 12 months. Both the quality and the appearance of the flaps were satisfactory. The blood supply and function of cnemis, ankle and foot returned to normal. Conclusion It is a convenient, simple and reliable method to repair softtissue defects in cnemis, ankle and foot with calf and sural distal fasciocutaneous flaps,without sacrifice of major arteries and with high survival rate and beautiful outlook form of skin flaps.
Objective To investigate the clinical effect of the reverse transposition of pedicled soleus muscle flap in repairing soft tissue defects after Pilon fracture fixation. Methods From May 2002 to June 2006, 14 patients (11 males, 3 females; aging 2050 years) with soft tissue defects afterPilon fracture fixationunderwent repairing operations with the reverse soleus muscle flaps. The soft tissue defects ranged from 7.0 cm×3.5 cm to 100 cm×60 cm. Of the patients, Pilon fractures were treated by internal fixations in 9 cases, open Pilon fractures weretreated by external fixations in 5 cases. The area of muscle flap ranged from 8.5 cm×5.5 cm to 12.5 cm×7.5 cm. Results All patients achieved primary healings, and the grafting skin survived. Twelve flaps survived completely but 2 flapshad mildinfection, which survived after dressing change. Eleven patients were followed up for 3 to 26 months, averaged 15 months. The flap appearances were good and smooth without ulceration. The dorsiflexion ranges of ankle joint were 10-25°, and plantar flexion ranges were 15-40°. The gait was normal. Conclusion The reverse soleus muscle flap is no need to reveal blood vessel pedicle and has constant position of anatomy. It has big muscle belly, convenient to move and circuitation 180°. It is profitable to reduce infection rate and to promote wound healing to raise local osteotylus.
