ABSTRACT
Objective:
To investigate the clinical effect of free chimeric bone flap pedicled with superficial palmar branch of radial artery in reconstruction of partial finger with composite tissue defect.Methods:
From July, 2018 to January, 2020, 9 cases of compound tissue defect of fingers were reconstructed by free transfer of chimeric bone flap pedicled with superficial palmar branch of radial artery. The wrist transverse striated flap and distal radius bone flap pedicled with superficial palmar branch of radial artery were harvested in operations. The size of flap were 2.0 cm × 4.0 cm -3.0 cm × 6.5 cm, and the length of bone flaps were 1.5-2.5 cm. All patients entered monthly follow-up by clinic visit in 6 months after the surgery, and thereafter by WeChat interviews.Results:
All of the 9 chimeric bone flaps survived well. The average healing time of bone flap was 1.7 months, and the average length of reconstructed finger was 2.4(1.8-3.0) cm; The appearance of the affected fingers restored well, the scars of the donor sites were mild, and average of the TPD of the flaps was 6.6(5.3-8.6) mm at 6 months after the surgery. The function of the affected finger was evaluated according to the Trial Standard of the Upper Limb Function Evaluation proposed by the Hand Surgery Society of the Chinese Medical Association excellent in 7 cases, good in 1 case and medium in 1 case.Conclusion:
Free chimeric bone flap pedicled with superficial palmar branch of radial artery can be used in reconstruction of the soft tissue and bone defects of fingers at the same time. It restores the functional length of fingers, improves the function and appearance of fingers, with less damage to the donor site. It is a simple method for reconstruction of finger defects.
