Diagnosis and management of musculoskeletal pain in the lower back, buttock, and hip can be complex due to the multilayered muscular anatomy in this region. Each structure or functional group (ie, hip abductors) may present as a local pain syndrome. Pain may arise from osseous, intra-articular, ligamentous, musculotendinous, myofascial, neural, or vascular sources. Diagnosis is challenging due to overlapping innervation and referred pain patterns, particularly sclerotomal referral from osseous and ligamentous structures. Effective treatment requires accurate diagnosis. A regionalized approach categorizing pain syndromes into 6 anatomic zones-above the iliac crest, the iliac crest, the lateral hip, the gluteal region, sciatic nerve related, and the ischial tuberosity-may improve diagnostic clarity and guide treatment. A regionalized, 6-zone framework for posterior buttock pain may enhance diagnostic accuracy and guide individualized management.
