Arthroscopic Iliopsoas Fractional Lengthening

Area of Science:

• Orthopedic Surgery
• Sports Medicine

Background:

• Internal snapping hip syndrome involves painful iliopsoas (IP) tendon snapping over the femoral head or iliopectineal line.
• Arthroscopic Iliopsoas Fractional Lengthening (IFL) is indicated for symptomatic cases unresponsive to conservative management.

Purpose of the Study:

• To describe the arthroscopic technique for Iliopsoas Fractional Lengthening (IFL).
• To detail the surgical steps and portal usage for IFL in hip arthroscopy.

Main Methods:

• Hip arthroscopy performed in supine position with traction.
• Utilized anterolateral, mid-anterior, and DALA portals for joint access.
• IFL performed from the central compartment by making a transverse cut in the tendinous portion of the IP tendon.

Main Results:

• The described technique allows for visualization and release of the iliopsoas tendon.
• Supplementary procedures like labral repair can be performed prior to IFL.

Conclusions:

• Arthroscopic IFL is a viable surgical option for internal snapping hip syndrome.
• The technique requires careful execution to release the tendon while preserving muscular portions.
