THR: Posterolateral Approach – Discussion

- Discussion:

- Anterior Capsule:
- a curved retractor is passed anterior to the anteior capsule and superior to psoas major tendon;
- retract femur anteriorly w/ a bone hook to keep capsule under tension;
- if sig flexion contracture is present before hip is dislocated, note tight structures capsule & insertions of rectus femoris & sartorius)
& incise them after dissecting along anterior border of Medius w/ hip flexed & externally rotated as such as possible;
- w/ relatively short head and neck segment, consider the need for complete capsulotomy during surgery;
- capsule is sectioned, allowing femur to be mobilized anteriorly w/ an intrapelvic cobra retractor placed just inferior to to ASIS
