Presentation
Fell onto right hip with tenderness on palpation. Post-operative bipolar hemiarthroplasty performed 3 days after initial presentation.
Patient Data
There is an acute right femoral neck fracture seen with no dislocation. The pelvic ring is intact. Degenerative changes of the lower lumbar spine are seen.
The right hip bipolar hemiarthroplasty implants are intact. Expected postsurgical soft tissue changes in the right proximal thigh and gluteal region are noted. The left femoral central venous line is in a satisfactory position.
Case Discussion
A hip hemiarthroplasty is one of the surgical treatments for femoral neck fractures. The implant, in this case, is a bipolar hemiarthroplasty, where the femoral head is also replaced to reduce the high risk of post-traumatic avascular necrosis.
Assessment 1 of a hip arthroplasty should include leg length, vertical & horizontal center of rotation, lateral acetabular inclination, and femoral stem positioning. The acetabular anteversion can be defined on a true lateral radiograph or a cross-table lateral view.
Post-operative notes on the implant used:
- J&J Summit
- femoral stem size 4
- shell 46mm
- standard +5mm
