- Discussion:
- anterior wall frx involve central portion of
anterior column & involves
iliopectineal line is involved;
- associated injury:
anterior hip dislocation;
- Technique of Fixation:
- anterior wall fractures are approached thru
Ilioinguinal Approach w/
supine positioning;
- traction removes femoral head from the centrally displaced position;
-
Reduction is achieved;
- fixation is with a curved plate placed along the pelvic brim from the
superior ramus to the internal iliac fossa;
- because screws are placed along brim, acetabulum can be easily entered;
- screws should be placed close to pelvic brim in direction parallel to the
quadrilateral surface;
- in area of pectineal eminence only short screw (approx 12-14 mm
long) is placed to avoid entering the joint;
- Anterior Wall Fracture: Implants:
- 6.5 mm cancellous bone screws as lag screws;
- 7.0 mm cannulated screws as lag screws;
- 4.0 mm cancellous bone screws;
- 3.5 mm reconstructed plate, curved;
