Background

Proximal femur tumor resection often leads to hip joint instability and functional loss.

Purpose

This study aims to evaluate the advantages and disadvantages of the ligament advanced reinforcement system (ligament advanced reinforcement system) tumor tube in assisting soft tissue function reconstruction in patients undergoing tumor type artificial hip replacement surgery.

Methods

Were followed up and postoperative functional evaluations were conducted using the Musculoskeletal Tumor Society (Musculoskeletal Tumor Society) scoring system and Harris hip joint scoring system to assess limb function and hip joint function.

n = 85 patients

89.6±5.3

Results

89.6±5.3

hip function was good on average after surgery, higher scores mean better function

n = 85 patients

More results

Preoperative pathological fractures were present in 37 cases (43.5%), with a lesion length of (9.4±2.9) cm.

Among non-metastatic tumor patients, 7 experienced postoperative recurrence, including 6 cases of osteosarcoma and 1 case of fibrosarcoma.

Pulmonary metastases occurred in 9 osteosarcoma patients.

More results

Postoperatively, 5 patients exhibited Trendelenburg gait, and 6 had leg length discrepancies.

“

Conclusion

The ligament advanced reinforcement system tumor tube can effectively assist in reconstructing the soft tissue function of the hip joint and greatly reduce postoperative complications, making it an effective technical improvement in joint function reconstruction in tumor type artificial hip replacement surgery.
