- Discussion:
- femoral neck frx may increase intracapsular pressure and capsular distention;
- this may decrease perfusion through the capsular vessels and contribute to development of
osteonecrosis;
- immediate
joint aspiration following
femoral neck frx may reverse intracapsular pressure and
AVN;
- Capsulotomy Technique:
- straight lateral incision is made from the top of the trochanter to point 1 cm distal to the lesser trochanter;
- fascia lata is incised longitudinally & vastus lateralalis either split or lifted anteriorly;
- capsular attachements at trochanteric ridge/vastus tubercle can be exposed with anterior retraction and the
capsule
incised in line w/ neck of the femur and released proximally and distally from intertrochanteric ridge to produce a T shaped capsulotomy;
