Summary
Extra-articular resection and reconstruction of the hip joint for bone sarcomas can yield good oncologic and functional results. Pelvic tumors present higher risks of recurrence and infection compared to femoral tumors.
Area of Science:
- Orthopedic Oncology
- Surgical Oncology
- Reconstructive Surgery
Background:
- Bone sarcomas of the hip joint require complex surgical management.
- Extra-articular resection offers a limb-sparing approach for hip joint tumors.
Purpose of the Study:
- To evaluate oncologic, functional, and clinical outcomes of extra-articular hip joint resection and reconstruction.
- To compare outcomes based on tumor location (pelvis vs. femur).
Main Methods:
- Retrospective review of 34 patients with hip bone sarcomas.
- Tumor resection and limb-salvage reconstruction performed between 1996 and 2016.
- Analysis of surgical margins, local recurrence, survival, complications, and functional scores.
Main Results:
- Clear surgical margins achieved in 91% of patients.
- Local recurrence occurred in 21%, predominantly in pelvic tumors.
- 3-year overall survival was 63%; common complications included deep infection and dislocation.
- Musculoskeletal Tumor Society scores were comparable between pelvic and femoral tumors.
Conclusions:
- Extra-articular hip joint resection is a viable option for oncologic and functional outcomes.
- Pelvic tumors are associated with increased risks of infection and local recurrence.
- Femur tumor resections are well-tolerated with good functional results.
