Compressed Fixation Combined with Vacuum-Assisted Closure for Treating Acute Injury of the Heel Fat Pad.

BACKGROUND Treating acute injury of the heel fat pad is different from treating common soft tissue damage. Due to the paucity of literature on the topic, we described our initial experience treating acute injury of the heel fat pad to determine the ideal treatment method. MATERIAL AND METHODS A total of 53 patients with acute injury of the heel fat pad admitted to our hospital were selected for the study and were randomly divided into 2 groups: the compressed fixation combined with vacuum-assisted closure group and the only reimplanted and sewn group. Twenty-seven of the heel fat pads were compressed and fixed using a flat, hard piece of plastic and hollow screws; then, they were covered with a vacuum-assisted closure device. The other 27 were only sewn without tension. The clinical results were evaluated according to the American Orthopedic Foot and Ankle Society hindfoot score and the British Medical Research Council function evaluation criteria RESULTS In the compressed fixation combined with vacuum-assisted closure group, flaps of 12 feet with retrograde avulsion injury survived successfully. Partial flap necrosis occurred in 8 feet. Seven feet underwent repair using the neurocutaneous vascular resupinated island flap. Results were excellent or good for 74% of patients according to the AOFS. However, in the only reimplanted and sewn group, results were excellent or good for 44% of patients according to the AOFS. CONCLUSIONS Compressed fixation with vacuum-assisted closure is effective for treating acute injury of the heel fat pad, with high success rates and good utility.

[Analysis of the vacuum sealing drainage technique combined with sural neurovascular pedicle fascio-cutaneous flap to repair deep wounds in the foot near the ankle joint with exposed bone and tendons].

OBJECTIVE: To evaluate the practical method of vacuum sealing drainage (VSD) technique combined with sural neurovascular pedicle fasciocutaneous flap to repair deep wounds in the foot near the ankle joint with exposed bone and tendons. METHODS: From January 2006 to January 2009, 79 patients with deep wounds in the foot near the ankle joint with exposed bone and tendons were treated by VSD technique combined with sural neurovascular pedicle fasciocutaneous flap including 58 males and 21 females with an average age of 34 years old ranging from 7 to 59 years. There were 17 cases in low 1/3 part of leg and achilles tendon, 28 in lateral malleolus and lateral dorsum of foot, 21 in medial malleolus and medial dorsum of foot, 13 in heel and pelma. Firstly the wounds were debrided and cultivated by using VSD technique, then the soft tissue defections were repaired with sural neurovascular pedicle fasciocutaneous flap. RESULTS: The area of flap was from 6 cm x 5 cm to 18 cm x 15 cm; All patients stayed in hospital for 14 to 30 days, 18 days in average. Living flaps of all patients were followed-up from 6 months to 3 years, the flaps of 2 patients were mostly necrotic, 3 were necrotic, 5 cases appeared obstacle of venous back streaming. The others survived with no infections. CONCLUSION: The wound would become fresh and clean as soon as possible with VSD. The sural neurovascular pedicle fasciocutaneous flap could provide a good covering for the exposed wound. Therefore the wound healed faster with friction resistance and fine appearance. The time of hospitalization were greatly shortened after combined application.
