Objective To investigate the effects of fibular head resection in prosthetic replacement for neoplasms of the proximal tibia in limb salvage surgery. Methods Between July 1999 and March 2013, 76 patients with neoplasms of the proximal tibia underwent tumor resection, prosthetic replacement, and gastrocnemius medial head flap transfer. Among them, 38 patients underwent fibular head resection (group A) and 38 underwent fibular head preservation (group B). There was no significant difference in gender, age, side, tumor classification and stage, and disease duration between 2 groups (P>0.05). The complications and the position of the components were observed, and American society for bone tumors scoring system (MSTS93) was used to evaluate the joint function. Results All patients were followed up 12-150 months (mean, 87 months). Incision infection occurred in 1 patient (2.63%) of group A and 6 patients (15.79%) of group B, showing significant difference (χ2=3.934, P=0.047). Necrosis of gastrocnemius medial head flap was found in 1 patient of group A and 2 patients of group B. Prosthetic loosening and instability of the knee were observed in 4 and 2 cases of group A and in 6 and 4 cases of group B, respectively. In groups A and B, there were 3 and 5 cases of local recurrence, 7 and 6 cases of distant metastasis, and 8 and 7 deaths, respectively. According to MSTS93, the results were excellent in 23 cases, good in 10 cases, fair in 3 cases, and poor in 2 cases, with an excellent and good rate of 86.84% in group A; the results were excellent in 21 cases, good in 11 cases, fair in 3 cases, and poor in 3 cases, with an excellent and good rate of 84.21% in group B; and no significant difference was found in the excellent and good rate between 2 groups (χ2=0.106, P=0.744). Conclusion Fibular head resection in prosthetic replacement for neoplasms of the proximal tibia in limb salvage surgery is beneficial to intra-operative tissue coverage, and it can reduce trauma by skin transplantation and related complications. Good stability and motion of the joint can be obtained after operation.
