Abstract:
Objective:To investigate the curative effect of transfer of free anteriolateral thigh flap (ALTF) with partial iliotibial tract on reconstruction of composite tissue defects in dorsal wrist/hand.Methods:Ten patients who were admitted in the Department of Hand Surgery of Yongkang Orthopaedic Hospital from March 2018 to August 2022 were entered in the study due to extensive composite tissue defects in dorsal wrists and hands. The patients were 24-48 (37 in average) years old. All patients had tendon defects in 3 or more digits with 35 digits in total. The length of the tendon defects were 5.0-11.0 cm in various digits. The soft tissue defects ranged from 6.0 cm×8.0 cm to 11.0 cm×21.0 cm in size. Six patients had defects accompanied with metacarpal and phalangeal bone fracture and joint capsule. In emergency surgery, all patients received thorough debridement and VSD coverage after internal fixation for combined fractures. At 3-5 days after the primary surgery, free ALTF transfer with partial iliotibial tract was employed to reconstruct the defects on dorsal wrists and hands and the digit extension function. The size of flap was 6.0 cm×9.0 cm-9.0 cm×17.0 cm, and the rest of defect wound was covered by skin graft. All the donor sites were sutured directly, except 1 that received abdominal skin graft. Patients had the follow-ups in outpatient clinics, or via telephone or Wechat, to observe the sensation and appearance of the flap, and the healing of the donor site. The recovery of the extension function of the hand was evaluated according to the totle active motion (TAM) system.Results:All flaps survived except one that had vascular compromise after the surgery and it survived after two explorations and a vascular transfer. Postoperative follow-ups lasted for 6 to 24 months, with 13 months in average. At the last follow-up, a all the flaps were found soft in texture and slightly swollen in appearance. There was no obvious pigmentation or rupture of skin and extensor tendon. Sensory recovery achieved to S 2 in 7 patients and S 3 in 3 patients. The hand function was evaluated according to TAM system and rated as excellent for 3 digits, good for 18 digits, fair for 9 digits and poor for 5 digits. There were linear scars in the donor sites. Conclusion:Free ALTF transfer with partial iliotibial tract in the reconstruction of composite tissue defect of dorsal wrists and hands can not only reconstruct the wound surface, but also the extension of digits, which cuts short the course of treatment.
