The Relationship Between Tensor Fascia Latae and Gluteus Maximus Has the Potential to Indicate Early Intra-articular and Degenerative Pathologies of the Femoral-Acetabular Joint: A Narrative Review.

UNLABELLED

Intra-articular and degenerative hip pathologies have become common place with the number of total hip replacements rising year on year in the United Kingdom (UK). Pathology is identified by clinicians using special tests which are researched maneuvers used by clinicians to rule in or rule out specific musculoskeletal pathologies. Special tests used for hip pathology usually have high specificity to exclude degenerative and intraarticular pathology but vary in sensitivity. These special tests are usually only conducted when a person is symptomatic and typically require radiological confirmation to diagnose. The aim of this review was to appraise research to determine whether functional changes in the TFL and UGM muscle complex could indicate degenerative and/or intra articular pathology, with a specific focus on the utility of the ratio in strength of TFL and UGM to assist clinical diagnosis. The hypothesis was that the ratio of the strength of Tensor Fascia Latae (TFL) and the upper fibres of Gluteus Maximus (UGM) could suggest early intra-articular hip pathology, and that changes to this ratio could indicate deterioration of the hip joint before symptoms present/progress.
