Abstract

Spondyloptosis is a type of severe spinal deformity that develops during childhood and progresses to adulthood. Spondyloptosis causes back pain, limited range of mobility, leg weakness and severe hamstring tightness. Correction of spondyloptosis requires careful preoperative analysis and special surgical techniques to ensure optimal nerve root stretch; both under-stretch and over-stretch pose a danger to the patient. In this paper, we describe a tensiometer useful for predicting impending nerve injury during spondyloptosis surgery.
