Surgical management of the spastic elbow.

Abstract

Background: We performed a retrospective review of patients undergoing surgery for elbow spasticity. We present our findings and expected outcomes according to degree of elbow fixed flexion contracture.

Methods: Data collected included age, Modified Ashworth Score, pre and post-operative range of motion, indications for surgery and the Goal Attainment Score. Contracture severity was classified into five groups based on goniometric measurements. Surgical procedures were categorised into three groups.

Results: A total of 114 elbows underwent surgical release. The mean age at surgery was 18.5 years and the mean follow-up was 20 months. Preoperatively, the median Modified Ashworth Score was 2 and the mean contracture was 68° (35° fixed and 33° dynamic). The median number of structures released was 3 (range: 1-6). Surgical procedures were classified as biceps sparing (27%), biceps lengthening (53%) and extended releases (18%). Mean improvement in extension was 59°, and the mean improvement in Goal Attainment Score was 36 (mean attainment score 62). The mean residual contracture was 9°. Patient satisfaction was high with over 90% of surgical indications met.

Discussion: Contracture severity of the spastic elbow can be categorised by degree of fixed flexion deformity and therefore treatment can be allocated accordingly.
