Advantages and Disadvantages, Including Risks and Limitations, of Arthroscopic Iliopsoas Fractional Lengthening With Access Using an Iliopsoas Air Bursogram

Advantages	Disadvantages, Risks, and Limitations
Direct access to the iliopsoas bursa allows for maintenance of intact hip capsule without violating the space containing the prosthetic implant.	Access medial to the capsule and implant is nearby the adjacent neurovascular structures.
Use of an iliopsoas bursogram allows for visual confirmation of correct anatomic structure to be exposed and released.	Injection to other nearby potential spaces may create (overlapping) soft tissue shadows that make subsequent successful generation and visualization of an air bursogram difficult.
The described technique can be performed percutaneously, with standard (scope) access cannulas, without the need for additional instrumentation or large cannulas.	Surgeons should be comfortable with percutaneous instrumentation of the medial hip. Consideration may be given to use of an instrument skid.
