About this episode

This episode discusses the impact of a leg length discrepancy on gait mechanics and the use of heel lifts as a structural intervention.

How do you determine when a leg length discrepancy requires structural intervention? In this episode of Untold Physio Stories , Dr. Wells presents a case study of an 80-year-old patient managing the long-term effects of a complex total hip replacement. Following a revision surgery two decades ago, the patient was left with a 2cm leg length discrepancy on her right side. While she remained active with yoga and Pilates for years, a recent decrease in activity led to noticeable changes in her gait and discomfort in her lower extremities. Structural Findings : A functional and anatomical measurement confirmed the right lower extremity was 2cm longer than the left. Gait Observations : Assessment revealed a compensatory trunk lean to the right to facilitate clearing the left leg during the swing phase. Joint Mechanics : The patient exhibited significant pronation in the right ankle and a varus thrust in the left knee during ambulation. Strength Deficits : Evaluation showed weakness in the left gluteal and quadriceps muscle groups. Dr. Wells opted for a dual-track approach: Conservative Structural Support : A 0.5-inch heel lift was introduced to the shorter side to improve gait symmetry…
