Total Hip Arthroplasty after Treatment of an Atypical Subtrochanteric Femoral Fracture in a Patient with Pycnodysostosis.

Yuasa T, Maeda K, Kaneko K, Yoshikata K - Case Rep Orthop (2015)

Bottom Line: She was of short stature with typical facial features, short stubby hands, and radiological features including open cranial sutures, obtuse mandible, and generalized skeletal sclerosis.The majority of cases of atypical subtrochanteric fractures are associated with long-term use of bisphosphonates; some occur in bisphosphonate-free patients.We performed cementless THA in combination with a plate and cables.

ABSTRACT
The authors describe the case of a 51-year-old woman with an osteonecrosis of her right femoral head after treatment of an atypical subtrochanteric fracture caused by pycnodysostosis. She had this fracture after a low-trauma fall. She was of short stature with typical facial features, short stubby hands, and radiological features including open cranial sutures, obtuse mandible, and generalized skeletal sclerosis. The majority of cases of atypical subtrochanteric fractures are associated with long-term use of bisphosphonates; some occur in bisphosphonate-free patients. We report a rare case of total hip arthroplasty (THA) in a patient with pycnodysostosis who developed an osteonecrosis of the femoral head after treatment of an atypical subtrochanteric femoral fracture. We performed cementless THA in combination with a plate and cables. Cementless THA is a potential intervention in a patient with pycnodysostosis; although the bone quality may have been sclerotic, healing is not a problem in this condition.

Mentions: One year and 4 months after operation, she was suffering from right hip pain and could not walk. Plain radiological examination revealed narrowing of joint space of the right hip joint and osteonecrosis of the femoral head (Figure 5). The adaptation of total hip arthroplasty due to osteoarthritis secondary to severe pain, limited ambulatory ability, and restriction of activities of daily life was determined (Harris hip score, 37).
