Bonesupport shares findings and experiences in a very detailed Case Report.

Patient

61-year-old male

Diagnosis

• Patient with history of wellpositioned, well-functioning bilateral uncemented THAs presented with progressive left hip pain over 6 months.
• X-rays showed a large cystic osteolytic lesion in the left acetabulum involving the superior dome and the medial wall with extension into the ischium.
• CT scan confirmed extensive amount of osteolysis.

Treatment

• Intraoperatively, significant wear of the polythylene liner allowing subluxation of the femoral head. The cup was solidly fixed and was not revised. The femoral head was exchanged for a new 32 mm head and the liner was exchanged to a10-degree elevated lip liner.
• A 2x2cm window was made above the acetabulum at the level of the cyst.
• The cyst was curetted and filled with 32cc CERAMENTTM|BONE VOID FILLER. Once CERAMENTTM solidified, the wound was irrigated and closed.

Outcome

• At 6 weeks post-op, the patient had good and painless range of motion and was weight-bearing without aides. X-rays confirmed good positioning of the acetabular implant CERAMENTTM|BONE VOID FILLER is still visible.
• At 8 months post-op, the patient was doing well and was pain-free. X-rays demonstrated CERAMENTTM|BONE VOID FILLER to be nearly completely resorbed and replaced with new cancellous bone.
