INTRODUCTION: Spastic foot deformity after central nervous system lesions is clinically heterogeneous and often combines equinus, varus, claw toes, pain, and gait limitation. Selective tibial neurotomy (STN) is a peripheral neurosurgical option for focal lower-limb spasticity, but data from low- and middle-income settings remain limited.
RESEARCH QUESTION: What are the long-term clinical and functional outcomes of STN for spastic foot deformity, and are these outcomes influenced by the extent of motor fascicle resection?
MATERIAL AND METHODS: We conducted a retrospective study of 31 patients (36 feet) who underwent STN. Deformity, clonus, ankle dorsiflexion, pain, gait performance, orthotic comfort, and patient satisfaction were assessed preoperatively and at long-term follow-up. The relationship between fascicle resection extent and outcomes was analysed.
RESULTS: Significant improvements were observed in equinus, varus, and claw-toe deformities, ankle dorsiflexion, and clonus (all p < 0.001). Pain resolved in all symptomatic patients, and toe-tip skin lesions markedly decreased. Walking distance increased significantly, and 10-m walking time improved. Orthotic comfort and patient satisfaction were high. Resection of more than two-thirds of fascicles was associated with better clonus and varus control.
DISCUSSION AND CONCLUSION: STN provides sustained clinical and functional benefits for spastic foot deformity. Greater fascicle resection may enhance outcomes in selected patients. This technique is feasible and effective in a Vietnamese neurosurgical setting.
