Evaluation and Management of the Snapping Iliopsoas Tendon

Diagnosis and Management of Snapping Hip Syndrome: A Comprehensive Review of Literature

“…A complex anatomic relationship exists between the iliopsoas tendon and the anterior surface of the hip, and many intra-articular hip pathologies as femoroacetabular impingement syndrome, labral tears ( Figure 9) and cartilage lesions can be associated with ISHS in more than 50% of the patients [34]. Endoscopic iliopsoas release may be performed at the level of the lesser trochanter by and additional portal, or by a transcapsular approach [2]. In this case, the iliopsoas tendon release is performed across the hip joint, and it is usually identify behind the anterior capsule at 3 o' clock.…”

“…The endoscopic release of the iliopsoas tendon can be performed at the lesser trochanter or by a transcapsular approach. The endoscopic release at the lesser trochanter was described by Byrd et al [2] in 2006, who reported good results in 9 patients, without complications or recurrence of symptoms. Others authors also reported good clinical results and low recurrence rate with this technique [28,29].…”

“…The prevalence of snapping hip is estimated to occur in up to 10% of the general population, but it may be higher in a selected population, in particular in athletes who require extreme hip ROM, as runners, soccer players, and weight lifters [2][3][4]. Winston et al [5] found that more than 90% of ballet dancers report a snap, crack, or dislocation sensation during certain movements that involve hip abduction and external rotation.…”

Case Report: Bifid Iliopsoas Tendon Causing Refractory Internal Snapping Hip

“…Treatment of painful internal snapping hip via arthroscopic release is becoming preferred over open techniques because of the benefits of minimal dissection, the ability to address concomitant intraarticular disorders, and a low complication rate [5,8,9,12]. Numerous authors have reported excellent results with arthroscopic iliopsoas tenotomy at 1 to 2 years postoperatively, with no refractory cases of snapping, minimal to no weakness, and a high prevalence of associated intraarticular disorders that can be managed arthroscopically at the same time [2,3,10,11,21].…”

Endoscopic Iliopsoas Tenotomy for Iliopsoas Impingement on a Collared Femoral Prosthesis

“…Both open and endoscopic techniques have been described, both aiming at lengthening or releasing of the tendon. [11][12][13][14][15][16] The results of endoscopic iliopsoas release are as good as the open results. [15][16][17][18] Encouraged by the good results reported with endoscopic release for internal snapping hip, similar techniques were used for iliopsoas impingement after THR.…”
