proximal hamstring tendinopathy
Degenerative condition affecting the hamstring tendons at their attachment to the ischial tuberosity, common in runners and dancers.
Full Definition
Proximal hamstring tendinopathy is a chronic degenerative condition affecting the origin of the hamstring muscles at the ischial tuberosity. This condition is particularly prevalent in distance runners, dancers, and athletes involved in sports requiring repetitive hip flexion and extension. The pathophysiology involves a continuum from reactive tendinopathy to tendon dysrepair and eventual degenerative tendinopathy. Unlike acute hamstring strains, this condition presents with insidious onset of deep buttock pain that may radiate down the posterior thigh. The pain is typically worse with sitting, particularly on hard surfaces, and during activities involving hip flexion with knee extension such as forward bending. Diagnosis can be challenging as symptoms may mimic piriformis syndrome or lumbar radiculopathy. MRI may show tendon thickening, signal changes, or associated bursitis.
Usage
Usage note: Distinguish from acute hamstring strain by chronicity and location of symptoms.
