The Peritrochanteric Space

• Space between the Greater Trochanter and Iliotibial Band

• Analogous to the subacromial space in the shoulder

Greater Trochanter Iliotibial Band

Peritrochanteric Space Pathology

•External Snapping Hip• Greater Trochanteric Pain Syndrome

– Recalcitrant Trochanteric Bursitis

– Gluteus Medius Tears

– Gluteus Minimus Tears

Greater Trochanteric Pain Syndrome (GTPS)

•Lateral sided hip pain and tenderness•Common clinical syndrome peaking between the 4th and 6th decades of life. 4♀:1♂

•Previously known as “Trochanteric Bursitis”– Bursal distention is actually uncommon

– Kingzett-Taylor et al, 1999– Bird et al, 2001

– The initial pathology usually occurs in the tendons attached to the greater trochanter. The adjacent bursae are secondarily involved.

– Gordon EJ, 1961

GTPS (cont.)

• Vast majority respond to conservative mgt.

• Recalcitrant cases are often due to gluteus medius or minimus tendon tears.

• Prospective MRI evaluation of 24 middle aged women with intractable GTPS

• 45.8% had gluteus medius tendon tears» Bird et al, 2001

• Prospective US evaluation of 75 pts with GTPS• 53/75 had gluteus medius tendinopathy• 25 of these 53 had full or partial g. medius tears

» Connell et al, 2002

Rotator Cuff Tears of the Hip

• Bunker et al, 1997• 22% of patients with femoral neck

fractures had gluteus medius tears

• Kagan A, 1999• Seven pts with recalcitrant GTPS

ranging from 2mos – 10yrs• Open repair through bone tunnels &

or side-to–side after debride• F/u at 45 mos, all were free of pain

• Howell et al, 2001• 20% of women undergoing THA for

OA had abductor tears

Page 10: Arthroscopic Treatment of Abductor Failure ICL 250: Advanced Surgical Techniques Wednesday, February 16 th, 2011 Bryan T. Kelly, MD Co-Director Center

Footprint Anatomy• Most gluteus medius tears occur anteriorly, at the

junction with the minimus.

Gluteus Medius Gluteus Minimus

•4 facets, 3 have distinct insertions

Page 12: Arthroscopic Treatment of Abductor Failure ICL 250: Advanced Surgical Techniques Wednesday, February 16 th, 2011 Bryan T. Kelly, MD Co-Director Center

Anterior Facet

• 2 parts to Gluteus minimus– tendon attachment lateral to joint capsule

– Muscular attachment to superior joint capsule

Page 13: Arthroscopic Treatment of Abductor Failure ICL 250: Advanced Surgical Techniques Wednesday, February 16 th, 2011 Bryan T. Kelly, MD Co-Director Center

Lateral Facet

• Middle and Anterior portions of the medius attach to the lateral facet

• Also continues anteriorly to cover insertion of minimus

Page 14: Arthroscopic Treatment of Abductor Failure ICL 250: Advanced Surgical Techniques Wednesday, February 16 th, 2011 Bryan T. Kelly, MD Co-Director Center

Superoposterior Facet

• Main insertion point for the posterior portion of the medius.

Page 15: Arthroscopic Treatment of Abductor Failure ICL 250: Advanced Surgical Techniques Wednesday, February 16 th, 2011 Bryan T. Kelly, MD Co-Director Center

Posterior Facet

• No muscle attachments• Trochanteric bursa

Page 16: Arthroscopic Treatment of Abductor Failure ICL 250: Advanced Surgical Techniques Wednesday, February 16 th, 2011 Bryan T. Kelly, MD Co-Director Center

Clinical Presentation: Recalcitrant GTPS – Abductor Tear

• Sometimes a history of a “pop” or sudden injury.

• Age group late 50’s to 60’s• Females > Males.• Failure of corticosteroid

injections.• Refractory lateral sided hip

pain.• Abductor weakness.• MRI confirmation.• In some (many ?) cases,

refractory trochanteric bursitis may be overlooked tears of the gluteus medius and minimus.

Arthroscopic Management

An arthroscopic approach through the peritrochanteric space is now possible for the repair of focal gluteus medius and minimus tendon tears.

Abductor Repair - Preparation• In some cases trochanteric spurs may be present that can be

burred down to created a better surface area for tendon healing.

ResultsArthroscopic Abductor Repair

•Results of 10 patients with minimum of 2 year f/u:

– All patients had complete resolution of pain in the lateral hip.

– 9 out of 10 (90%) had 5 out of 5 abductor muscle strength and one patient had 4 out of 5 strength.

– All patients maintained full hip range of motion.

ResultsArthroscopic Abductor Repair

•Modified Harris Hip Scores at one year averaged 92.2 points (range 72-100) and Hip Outcomes Score 93.1 points (range 85-100).

•7 out of 10 patients said their hip was normal and 3 said their hip was nearly normal.

ConclusionAbductor Repair

• Endoscopic repair of the gluteus medius tendons to the greater trochanter can be performed in a predictable manner.

• In the short term, resolution of pain and return to activity is predictable.

• Long term follow-up and a larger number of patients in prospective trials will provide further insight into the treatment of abductor repairs.
