Degenerative Disc Disease, Herniated Nucleus Pulposus, Spondylolisthesis

Brief summary

The purpose of this study is to assess the course of hip weakness after LLIF or ALIF procedures. These outcomes include measures of hip strength using a dynamometer, which is a device used to measure muscle strength. While it is known that people experience temporary hip and leg weakness after an LLIF or ALIF, the exact timing of when hip and leg strength is regained after an LLIF or ALIF is not known.

Primary

MeasureTime frameDescription
Hip flexion and knee extension strength as measured by the Lafayette Instrument Manual Muscle Testing Device (Dynamometer).Assessing changes in hip flexion and leg extension strength from the preoperative baseline to postoperative measurements taken at 6 weeks, 12 weeks and 6 months following lumbar fusions.Using a Lafayette Instrument Manual Muscle Testing Device (Dynamometer), we will be measuring the force in pounds a given patient can exert upon hip flexion and knee extension at the preoperative timepoint and 6 weeks, 12 weeks and 6 months postoperatively.
