Ectopic bone after hip replacement. Excision and free fat transplants in four cases
Acta Orthopaedica Scandinavica
|December 1, 1984
Summary
Free fat transplants effectively treated ectopic bone formation after hip replacement surgery. Patients experienced significant pain relief and improved hip mobility, with reduced or absent bone regrowth one year post-procedure.
Area of Science:
- Orthopedic Surgery
- Regenerative Medicine
- Biomaterials
Background:
- Ectopic bone formation is a complication following total hip replacement.
- This can lead to pain and limited joint mobility.
Purpose of the Study:
- To evaluate the efficacy of free fat transplantation in treating heterotopic ossification after total hip replacement.
- To assess the impact of fat grafting on pain and hip function.
Main Methods:
- Four patients with ectopic bone post-hip replacement received free fat transplants.
- Clinical outcomes including pain and hip flexion were assessed one year later.
- Bone scintigraphy was used to monitor ectopic bone formation.
Main Results:
- Patients reported significant pain relief and an average increase of 60 degrees in hip flexion.
- Ectopic bone was completely resolved in one patient and markedly reduced in three others.
- Bone scintigraphy effectively detected early ectopic bone formation.
Conclusions:
- Free fat transplantation is a promising treatment for ectopic bone after hip replacement.
- Fat grafting can alleviate pain and improve hip function.
- Bone scintigraphy is a valuable tool for monitoring ectopic bone development.
