Ligamentum teres tendinopathy and tears

Abstract

SummaryBackground: The ligamentum teres (LT) consists of two bands that originate on the ischial and pubic sides of the acetabular notch and insert on the fovea capitis of the femoral head. Recent studies have established the LT as an important hip stabilizer in a squatting position, particularly in patients with osseous instability. Purpose: This review aims to concisely present the literature on LT tendinopathy and tears in order to guide health care professionals in the appropriate diagnosis and treatment of these disorders. Methods: We reviewed the literature on the diagnosis and surgical management of ligamentum teres tendinopathy and tears. Conclusions: The ligamentum teres is an important stabilizer to the hip joint, particularly with hip flexion and external rotation. Older age and acetabular bony pathomorphology are two of the known risk factors for LT tears. Symptoms of LT tendinopathy are largely non-specific, mimicking a wide range of other hip disorders including impingement and instability. Debridement of LT tears or reactive tissue has been reported with good outcomes, with more recent studies describing reconstruction of a completely torn, nonfunctional, or absent LT using various graft sources including synthetic grafts, autografts, and allografts. Level of evidence: II.

Upsloping lateral sourcil: a radiographic finding of hip instability

“…All patients underwent routine comprehensive physical examination of the lower spine and lower limbs with emphasis on the evaluation of hip pain and generalized joint laxity. Passive hip range of motion (supine, lateral, prone), the FADIR (flexion, adduction, internal rotation) test, the FABER (flexion, abduction, external rotation) test, the ligamentum teres test, the posterior impingement test and use of the Beighton Hypermobility Score (BHS) [28]. BHS was categorized as follows: no laxity (0–2 points), mild laxity (3–5 points), moderate to severe laxity (6–9 points).…”
