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 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.

Posttraumatic stress disorder (PTSD) is a kind of mental disorder associated with traumatic experiences. The core symptoms of PTSD include intrusions, avoidance of trauma reminders, negative alterations in cognitions and mood and alterations in arousal. Cognitive processing therapy (CPT) may reduce PTSD symptoms by changing the connectivity of cerebellum, central executive network, and default mode network through the core therapeutic steps of preventing avoidance, releasing true emotion, and recognizing and challenging "stuck points". At present, a large number of empirical studies abroad have certified the significant efficacy of CPT, but it has not been widely promoted in China. Therefore, this article intends to summarize the clinical application of CPT in different populations and its possible therapeutic mechanism, in order to provide evidence-based medical evidence for the localization and clinical application in China.

This is a report of a complex defects in the right upper extremity treated in the Department of Hand and Microsurgery, 521 Hospital of Norinco Group, in October 2016. The patient received multi-transfers of flaps for one-stage reconstruction, including a double-paddled ALTPF and a compound flap of the great toe and the second toe. Vascular compromises occurred in flaps on the 2nd day after surgery. All the flaps were rescued and survived completely after surgical exploration. Followed-up at 3 year after surgery showed that the appearance and function of the affected limb recovered well. The flexion and extension of elbow and wrist were normal. The pinch function of the reconstructed thumb and index finger recovered well.

Objective To explore the clinical effects of sequential flap of thigh perforator for closure of the anterolateral thigh free flap donor site.Methods From March,2014 to May,2015,8 consecutive patients underwent elective anterolateral thigh free flap reconstruction for limb soft tissue defect.To design a sequential flap of thigh perforator to achieve primary closure of the anterolateral thigh free flap donor site.The area of anterolateral thigh free flap ranged from 9.0 cm×6.0 cm to 20.0 cm×1 1.0 cm,respectively.The area of thigh perforator flap ranged from 7.0 cm×3.0 cm to 12.0 cm×7.0 cm.Results All flaps healed uneventfully.Distal skin flap necrosis appeared in 1 flap which was healed after local transposition flap.All the patients were followed up for 1 to 6 months,with mean time of 4 months.The color,texture and appearance of flaps were satisfactory.Conclusion Sequential flap of thigh perforator,with reliable blood supply and constant position,represents an ideal model to close the anterolateral thigh free flap donor site of small defect.
