Summary
Metastasis can spread to bone around total hip arthroplasty, causing loosening. Revision surgery with metaphysodiaphyseal implants is a viable treatment option for these complex cases.
Area of Science:
- Orthopedic Surgery
- Oncology
- Radiology
Background:
- Total hip arthroplasty (THA) is a common procedure for osteoarthritis.
- Carcinoma metastasis can affect bone surrounding prosthetic implants.
- Prosthetic loosening is a potential complication of periprosthetic metastasis.
Observation:
- Three cases of carcinoma metastasis to bone around THA are presented.
- Metastases originated from kidney, prostate, and breast cancers.
- The bony metastases led to loosening of the hip prostheses.
Findings:
- All three patients required revision surgery with metaphysodiaphyseal implants.
- One patient with a seemingly solitary metastasis underwent oncological resection.
- The patient who underwent resection was disease-free at two-year follow-up.
Implications:
- This highlights the importance of considering metastatic disease in patients with hip pain after THA.
- Metastasis to bone around THA can compromise implant stability.
- Surgical intervention, including revision arthroplasty and oncological resection, can be effective in managing these cases.
