Abstract:
Objective:To investigate the clinical effect of the repair and reconstruction of severe foot trauma by microsurgical methods.Methods:Patients with severe foot trauma were admitted to Xinhua Hospital (Chongming), Affiliated with Shanghai Jiao Tong University School of Medicine, and Taizhou Hospital, Affiliated with Wenzhou Medical University in Zhejiang Province from November 2008 to October 2019. All patients were treated with orthotopic replantation using microsurgical anastomosis in emergency and precise microsurgical reconstruction in the second stage. A retrospective analysis of the clinical effect of the reconstructed appearance and function was performed. The evaluation and surgical design were carried out according to the characteristics of the injury site, range, plane, degree, etc., and adequate debridement and orthotopic replantation of residual tissue was performed under the microscope in emergency. Then regular follow-up was conducted to evaluate the postoperative efficacy, the degree of foot swelling, and the observation of foot activity and function.Results:A total of 23 patients with severe foot trauma were enrolled, including 15 males and 8 females, aged from 17 to 69 years old, with an average of 38.5 years old. Among them were the left foot in 10 cases and the right foot in 13 cases. 15 of the 23 patients survived orthotopic replantation. 2 cases of medial plantar skin necrosis were treated by skin graft in the second stage, 1 case of heel skin necrosis and 2 cases of anterior plantar skin necrosis with infection were repaired by flaps, and 3 cases of dorsal skin necrosis with infection combined with bone defect were repaired by flaps or osteocutaneous flap. After the operation, 23 patients were followed up for 6 to 48 months, with an average of 18.5 months. The wounds were completely healed, the color and elasticity were close to the surrounding normal skin, and there was no apparent swelling deformity on foot. The sensory function of the foot was all restored to grades S3-S4, with a small scar, and they walked freely without noticeable limping. The efficacy was evaluated according to a survival situation, color elasticity, appearance and morphology, donor scar, skin sensation, infection control, and patient recognition. 16 cases were satisfied with the outcomes, and 7 reported moderate. Skin swelling rating in the early stage was 1st degree in 3 cases, 2nd degree in 10 cases, 3rd degree in 8 cases, 4th degree in 2 cases; in the later stage was 1st degree in 15 cases, 2nd degree in 6 cases, 3rd degree in 2 cases. Foot function is assessed by the degree of postoperative pain, function of flexion and extension, degree of deformity, and walking ability, which is excellent in 3 cases, good in 13 cases, general in 7 cases, with a reasonable rate of about 69.6%(16/23).Conclusions:The microsurgical technique is one of the most effective methods to repair and reconstruct the function and appearance of the foot with severe trauma for now.
