Objective:To investigate a surgical method and clinical effect on reconstruction of infective ulcer and soft tissue defects in dorsal fingers of the elderly patients with free perforator flap of peroneal artery.Methods:From March 2016 to June 2022, 13 elderly patients with infective ulcer and soft tissue defects in dorsal fingers were reconstructed with free perforator flaps of peroneal artery. The patients were 65-70 years with an average age of 66.5 years. Cause of infection: 10 ulceration and soft tissue defects were caused by diabetes and 3 by injury. Seven infective ulceration and soft tissue defects were in dorsal index fingers, 3 in dorsal middle fingers and 3 in dorsal ring fingers with the size of soft tissue defects at 2.0 cm×4.5 cm-2.0 cm×5.5 cm with an exposure of tendon and phalange. The donor site of the flaps was of contralateral calf and the flaps were 2.5 cm×5.0 cm-2.5 cm×6.0 cm in size. All donor sites were sutured directly. All patients were included in the postoperative follow-up at outpatient clinic to observe the appearance and sensation of the flap as well as finger movement.Results:All flaps survived and all wounds achieved stage I healing, without recurrence of infection. Twelve patients had the postoperative follow-up for 12 to 27 months, with an average of 21.6 months. There were satisfactory appearance of flaps and the function of fingers. Sensation of flaps recovered to S 2 in 5 patients and S 3 in 7 patients. The recovery of hand function was evaluated according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, with 8 hands in excellent and 4 in good. Conclusion:The free perforator flap of peroneal artery has advantages of constant vascular anatomy, reliable blood supply, moderate thickness and direct closure of donor site. It is a useful clinical method in reconstruction of infective ulcer and soft tissue defects in dorsal fingers of the elderly patients.

Objective:To explore the therapeutic effect of micro-flaps carrying sensory nerve in treatment of high-pressure injection injuries of the digit (HPIID).Methods:From January 2022 to June 2024, retrospective analysis of 7 patients who had HPIID were admitted to the Department of Hand Surgery Division 1, Norinco General Hospital. The patients were 5 males and 2 females with ages from 25 to 59 years. The digital injuries were: 3 index fingers, 2 middle fingers and 2 thumbs. All patients received debridement under microscope in primary surgery, with the defects at 1.5 cm×2.4 cm - 2.5 cm×5.5 cm in size after debridement. In stage Ⅱ surgery, 5 patients received the treatment of free fibular great toe flap carrying peroneal nerve of the great toe, with the flap size at 1.8 cm× 2.0 cm - 2.7 cm×4.0 cm. Two patients received the treatment of transfer of free fibular medial plantar flap carrying medial plantar nerve, with flap size at 1.9 cm×2.6 cm - 4.5 cm×5.7 cm. Donor sites were directly sutured in 5 patients, and 2 patients received skin grafting. Five patients received postoperative follow-up at outpatient clinic, 1 patient via telephone interview and 1 via WeChat review.Results:All 7 flaps survived and all wounds had primary healing. All donor and recipient sites and skin grafting sites healed primarily. Postoperative follow-up lasted for 4 to 9 months, with an average of 6.4 months. All the affected digits had satisfactory appearance and function, except 1 which was slightly slimmer than the healthy side. Range of motion of the affected digits was evaluated according to total active movement (TAM): 5 were in excellent and 2 in good. Sensory recovery of the digits was evaluated according to the British Medical Research Council (BMRC): 1 digit was at S 2, 2 at S 3 and 4 at S 4. One patient had two-point discrimination (TPD) at 9.0-15.0 mm, 2 at 6.0-10.0 mm, and 4 at 3.0-6.0 mm. Conclusion:For HPIID with a defect, surgical treatment with transfer of micro-flap carrying sensory nerve should be a preferred treatment option.

Objective:To investigate the clinical effects of Masquelet technique with the transfer of free iliac inguinal flap in reconstruction of infectious bone and soft tissue defect after metacarpal fracture surgery.Methods:From January 2014 to January 2020, 16 patients suffered from infectious bone and soft tissue defect after surgery of metacarpal fracture were treated in Department of Hand Surgery, Institute for Hygiene of Ordnance Industry (Weapon Industry 521 Hospital). Debridement and vacuume sealing drainage (VSD) coverage of wound were carried out in emergency surgery, and Masquelet technique combined with free iliac inguinal flap for reconstruction of infected metacarpal bone defect were performed in sub-emergency surgery. The patients were 14 males and 2 females with an average age of 38 (20-50) years old. Plates were removed in 10 patients and retained in 6 patients. Defects of metacarpal bone ranged from 0.8 cm×0.8 cm×2.0 cm to 1.5 cm×2.0 cm× 5.1 cm in size. Soft tissue defects ranged from 3.6 cm×6.8 cm to 7.8 cm×11.6 cm. Tendon defects were found in all 16 patients. After the primary procedure of Masquelet technique combined with free iliac inguinal flap, routine anti-infection, anticoagulant, antispasmodic and other treatments were offered to all patients. Then all patients were observed by fortnightly reviews. After infection was cleared, the second phase of Masquelet treatment began. The defects of metacarpal bone were reconstructed with autologous cancellous bone grafts, and measures to prevent from infection together with other therapies were offered after the surgery. Follow-up of the second phase surgery was carried out once per 1-2 weeks and then per 2-4 months after bone union. The follow-up review items included: wound infection and necrosis, appearance, shape, texture and sensory recovery of flap. Bone union of infectious metacarpal defect was evaluated, recurrence of infection was closely observed as well as the resorption or nonunion of bone by X-rays. Hand function was assessed according to the Evaluation Trial Standards of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association. Donor sites healing and functional recovery were also included in the postoperative observation.Results:The follow-up time ranged from 1.5-3.0 (average 2.4) years. There was no necrosis of iliac inguinal flap, no recurrence of infection, and the flaps all healed well. The appearance, shape and texture of flaps were found close to the adjacent skin in all patients. Two-point discriminations (TPD) of the transferred iliac inguinal flaps were at 8-10 mm. X-ray reviews showed that bone union achieved in all patients. The time of bone union were 2.1-3.4 months (2.9 months in average) after bone grafting. There was no bone resorption, infection or nonunion. According to the Evaluation Standard of Upper Limb Partial Functional of Hand Surgery of Chinese Medical Association, 13 patients were excellent and 3 patients were good. All donor sites had primary healing with the motion of donor hips unaffected.Conclusion:Masquelet technique combined with free iliac inguinal flap is an effective, safe and feasible surgical procedure in reconstruction of infectious bone and soft tissue defect after metacarpal fracture surgery. It offers a satisfactory outcome with relatively less damage to the donor site.

OBJECTIVE: To investigate the effectiveness of dorsal perforator flap of cross-finger proper digital artery in the treatment of finger soft tissue defect caused by high-pressure injection injury. METHODS: Between July 2011 and June 2020, 14 cases of finger soft tissue defect caused by high-pressure injection injury were repaired with dorsal perforator flap of cross-finger proper digital artery. All patients were male, with a mean age of 36 years (range, 22-56 years). The defects were located on the index finger in 8 cases, middle finger in 4 cases, and ring finger in 2 cases. The causes of injury include 8 cases of emulsion paint injection, 4 cases of oil paint injection, and 2 cases of cement injection. The time from injury to debridement was 2-8 hours, with a mean time of 4.5 hours. The soft tissue defects sized from 4.0 cm×1.2 cm to 6.0 cm×2.0 cm. The flaps sized from 4.5 cm×1.5 cm to 6.5 cm×2.5 cm. The donor site of the flap was repaired with skin graft. The pedicle was cut off at 3 weeks after operation, and followed by functional exercise. RESULTS: All flaps and skin grafts at donor sites survived, and the wounds healed by first intention. Twelve patients were followed-up 16-38 months (mean, 22.6 months). The texture and appearance of all flaps were satisfactory. The color and texture of the flaps were similar to those of the surrounding tissues. The two-point discrimination of the flap was 10-12 mm, with a mean of 11.5 mm. There were different degrees of cold intolerance at the end of the affected fingers. At last follow-up, the finger function was evaluated according to the Upper Extremity Functional Evaluation Standard set up by Hand Surgery Branch of Chinese Medical Association, 3 cases were excellent, 8 cases were good, and 1 case was poor. CONCLUSION The dorsal perforator flap of cross-finger proper digital artery can effectively repair finger soft tissue defect caused by high-pressure injection injury. The operation was simple, and the appearance and function of the finger recover well.
