  • VENOUS SKIN GRAFT IN THE REPAIR OF SKIN DEFECTS OF FINGER REGION

    Patients receiving venous skin grafts having 3 different patterns of nutrient supply were introduced. It was considered that the venous skin graft had contain role in the repair of skin defects of fingers and dorsum of hands. The mechanism of the survival of the venous skin graft was discussed. It was assumed that, in the early stage, the skin nutrient was possibly in relation with the effusion or exudation from the wound surface, and in the later stage, depended upon the collateral circulation established with the surrounding tissues.

  • ECONSTRUCTION OF THUMB AND FINGER USING FREE NEUROVASCULAR BIG TOE NAIL SKIN FLAP WITH FROZEN FINGER COMPOSITE ALLOGRAFT AND SECOND TOE FREE GRAFT

    From April 1984 to March 1994, 31 reconstructive thumbs or fingers were followedup, including 16 cases with free neurovascular big toe nail skin flap and frozen preserved phalanxjointtendon composite allografts as well as 15 cases withfree second toe transfer. The method had the advantage of more fingers could bereconstructed and fewer toes would be lost. The decision of the site of reconstruction of finger, the augmentation of narrow web space between the thumb and the index finger, the prevention and treatment of vascular crisis and the degeneration of allogenic joint were discussed. It had been found that preserving the allogenic finger below -30℃ may lower the immunoreaction of the allogenic tissues. It was emphasized that the viable tissues should be preserved during the emergency debridement, so as to facilitate the following reconstruction procedure.

  • PATHOGENESIS OF SWAN-NECK DEFORMITY OF FINGERS AFTER BURN AND ITS TREATMENT

    The surgical treatment of 20 cases (58 fingers) of swan-neek deformity of fingers after burns was reported. The operativc techniques included: (1) The cicatrix at the dorsal aspect of the finger was relcased and the raw surface thus formed was covered by skin graft, while the palmar skin was tightened; (2) Thc extensor mechanism of the finger was partially resected with relcase of the interosscous muscles and shortening of tcnodesis of the tendon of flexor digitorum superficialis; and (3) Fusion of the interphalangeal joint. The results of various methods of treatment were analyzed, and the pathogenesis of swan-neck deformity of fingers was discussed. The importance of prevention of its occurrence was emphasized.

  • DOUBLE ADJACENT-FINGER SKIN FLAP IN THE TREATMENT OF SEVERE CICATRICIAL CONTRACTURE OF FINGERS

    Double adjacent-finger skin flap could be used to treat severe cicatricial contracture of fingers with resultant complete release of contracture and good coverage of raw surface. From the follow-up, it was noted that the appearance of the fingers following treatment looked nice, no recurrence of contracture in the late stage, and partial sensation of the fingers could be recovered as well. It had no ill-effect on the donor fingers, The method was simple and reliable,from 1987, a total of 4 cases had been done,and the functional recovery wassatisfactory.

  • Treatment of irreducible intertrochanteric femoral fractures in elderly by novel bone hook combined with finger-guided technique

    Objective To investigate the feasibility and effectiveness of the novel bone hook combined with finger-guided technique in the treatment of irreducible intertrochanteric femoral fractures in elderly. Methods Between January 2021 and August 2023, 23 elderly patients with irreducible intertrochanteric femoral fractures were treated with the novel bone hook combined with finger-guided technique. There were 10 males and 13 females; the age ranged from 68 to 93 years (mean, 76.2 years). The time from injury to operation ranged from 36 to 76 hours (mean, 51.2 hours). According to the classification standard proposed by TONG Dake et al in 2021, there were 10 cases of typeⅠA, 1 case of typeⅠB, 6 cases of type ⅡA, 4 cases of type ⅡB, and 2 cases of type ⅡC. The operation time, intraoperative blood loss, intraoperative fluoroscopy frequences, and quality of fracture reduction were recorded. The fracture healing time and occurrence of postoperative complications were observed during follow-up. At last follow-up, the Harris scoring system was used to evaluate the hip joint function. Results The operation time was 42-95 minutes (mean, 52.1 minutes). The intraoperative blood loss was 40-420 mL (mean, 126.5 mL). Intraoperative fluoroscopy was performed 14-34 times (mean, 20.7 times). According to the criteria proposed by Chang et al, the quality of fracture reduction was rated as good in 20 cases and acceptable in 3 cases. All patients were followed up 6-20 months (mean, 10.2 months). X-ray film showed that all fractures healed with the healing time of 3.0-5.5 months (mean, 4.0 months). At last follow-up, the Harris score of the hip joint ranged from 82 to 97 points (mean, 90.4 points). Among them, 14 cases were rated as excellent and 9 cases as good. No complication such as coxa vara, cutting of the cephalomedullary nail, nail withdrawal, or nail breakage occurred during follow-up. Conclusion The treatment of elderly patients with irreducible intertrochanteric femoral fractures by using the novel bone hook combined with finger-guided technique can achieve high-quality fracture reduction and fixation, and has a good effectiveness.

  • Application of groin flap combined with medial plantar artery perforator flap for degree Ⅲ-Ⅳ defects of multiple fingers

    Objective To investigate the effectiveness of groin flap combined with medial plantar artery perforator flap (MPAP) for degree Ⅲ-Ⅳ defects of multiple fingers. Methods Between January 2018 and June 2019, 12 patients with degree Ⅲ-Ⅳ defects of multiple fingers caused by crushing were admitted. There were 9 males and 3 females with a median age of 29 years (range, 16-42 years). The mean interval between the injury and admission was 3 hours (range, 1-9 hours). The injured fingers of 7 cases were index and middle fingers, 4 cases were middle and ring fingers, and 1 case was index, middle, and ring fingers. All fingers were taken thorough debridement and covered by the vacuum sealing drainage device during the emergency operation. The mean interval between the debridement and flap repairing was 18 hours (range, 12-36 hours). During the first-stage operation, the iliac bone graft was used to reconstruct bone frame, and the proximal interphalangeal (PIP) joint from the foot was transferred as the digital PIP joint, then the thin groin flap and MPAP were tailored to cover the dorsal and palmar defects, respectively. The size of the groin flap was 7.0 cm×4.5 cm-14.0 cm×9.0 cm, and the size of the MPAP was 8.0 cm×4.5 cm-14.0 cm×6.5 cm. The abdominal donor site was directly sutured, and the foot was repaired with full-thickness skin grafting. The flaps were separated into the finger shape at the second-stage. Results All the flaps survived, and the wounds healed by first intention; the incisions in the donor site healed by first intention, and the skin grafts survived completely. All patients were followed up 12-18 months (mean, 16 months). At last follow-up, the injured finger was similar to the contralateral one in terms of texture, appearance, and color. The mean two-point discrimination was 8 mm (range, 6-10 mm), and the sensate level recovered to the S3-S4. According to the Michigan Hand Outcomes Questionnaire (MHQ), the reconstructed hand function was excellent in 8 cases and good in 4 cases. There was no complication in the donor sites. Conclusion The degree Ⅲ-Ⅳ defects of multiple fingers were repaired by the groin flap and MPAP, and the reconstructed fingers can perform good texture and motion with being sensate, with less sacrifice on the foot.
