Internal Snap of the Psoas (Iliopsoas) Tendon

The treatment for internal snapping of the hip may consist of a psoas tendon release in those patients who have failed nonoperative treatments and who have persistent pain. Nonoperative treatment for an internal snap typically consists of injections and avoidance of repetitive snapping if possible. Patients typically complain of a snap or click in the hip and on physical examination the snap can often be reproduced. Oftentimes there are other associated abnormalities in the hip that may be causing pain and that may need to be addressed. If there is no pain associated with the snap, typically no additional treatments are necessary. I have recently added a video to my website through youtube that demonstrates the arthroscopic surgical technique. Once the joint has been accessed arthroscopically, the procedure typically takes about 5 minutes to complete.

Types of treatment of hip labral (labrum) tears

There are 4 main treatment options for the treatment of labral tears. The best way to treat specific patterns of damage has not been fully clarified in publications on hip arthroscopy, but here I present some guidelines:
1. Debridement: This has been historically the main treatment for labral injury. This treatment is performed via hip arthroscopy and essentially consists of removing the damaged tissue with a shaver and/or with an electrocautery device. I perform this technique rarely, as preservation of this tissue when possible is beneficial.
2. Repair: This treatment also is performed via hip arthroscopy and consists of placing suture anchors in the bone and reattaching the labral tissue after it has been prepared. There is increasing evidence that this technique of repair is superior to debridement when possible.
3. Reconstruction: Also performed via hip arthroscopy, this technique may be performed when the labral tissue is too damaged or too small to be repaired. The technique consists of replacing the labrum with new tissue, and may be performed with autograft or allograft tissue.
4. Joint replacement: When the labral damage is associated with significant hip arthritis, the best treatment option is a hip replacement.

All arthroscopic allograft reconstruction of hip labral tear and deficiency

A young active patient who had previously undergone hip arthroscopy and labral debridement was reconstructed with allograft tissue. This was featured in a Channel 10 news story

Femoroacetabular Impingement

Ganz and colleagues recently described the concept of femoroacetabular impingement (FAI) as a source of labrum (labral) tears and articular cartilage injury. Two bony abnormalities, CAM and pincer, frequently occur together. CAM impingement results from abnormal contact between an abnormally shaped femoral head and neck with a morphologically normal acetabulum. This type of impingement may be of unknown cause or may be associated with femoral neck fractures that have healed incorrectly, slipped femoral capital epiphysis, or Legg-Calve-Perthes disease. Pincer impingement results from abnormal contact between a normal femoral head with an abnormal acetabulum. This type of impingement is the result of focal (acetabular retroversion) or global (deep socket) over-coverage.

Because of its association with articular cartilage injuries and labral tears, there is considerable overlap in terms of presenting symptoms. Asymmetrical range of motion, especially into flexion-internal rotation or flexion–abduction–external rotation, may be noted. Radiographs and MRIs are the current standard to assess for FAI.

Open or arthroscopic surgical interventions include osteoplasty to reshape the head – neck junction of the femur or rim trimming to remove excessive bone from the acetabular rim.

Impingement is due to a bony abnormality and therefore no true preventative measure can be taken. Proper maintenance of core strength and muscle balance in and around the hip may help protect the soft tissues in the joint.
