Snapping Hip Syndrome: A Comprehensive Update

Paul Walker et al. Orthop Rev (Pavia). .

Abstract

Purpose of review: This is a comprehensive literature review regarding the pathogenesis, diagnosis, and treatment of snapping hip syndrome (SHS). It covers the diverse etiology of the syndrome and management steps from conservative to more advanced surgical techniques.

Recent findings: Recent advances in imaging modalities may help in diagnosing and treating SHS. Additionally, arthroscopic procedures can prove beneficial in treating recalcitrant cases of SHS and have recently gained popularity due to their non-invasive nature.

Summary: SHS presents as an audible snap due to anatomical structures in the medial thigh compartment and hip. While often asymptomatic, in some instances, the snap is associated with pain. Its etiology can be broadly classified between external SHS and internal SHS, which involve different structures but share similar management strategies. The etiology can be differentiated by imaging and physical exam maneuvers. Treatment is recommended for symptomatic SHS and begins conservatively with physical therapy, rest, and anti-inflammatory medications. Most cases resolve after 6-12 months of conservative management. However, arthroscopic procedures or open surgical management may be indicated for those with persistent pain and symptoms. Different surgical approaches are recommended when treating internal SHS vs. external SHS. Due to advancements in treatment options, symptomatic SHS commonly becomes asymptomatic following intervention.
