Cementoplasty in the treatment of avascular necrosis of the hip.


OBJECTIVE: This retrospective study evaluated the role of percutaneous cementoplasty in the treatment of avascular necrosis (AVN) of the hip in order to postpone or avoid total hip replacement. METHODS: The study population comprised 40 patients (47 hips) with mean age of 46 +/- 4.7 years and mean body mass index of 26.7 +/- 4.6 kg/m(2). AVN was classified according to the Ficat-Arlet classification as one stage I, 30 stage II, and 16 stage III. The minimum followup was 9 months. RESULTS: It was found that 74.5% of hips were secondarily operated for total hip replacement a mean of 19.9 +/- 15 months (median 14 mo) after cementoplasty. As well, 94% of patients with stage 3AVN and 68% with stage 2AVN underwent surgery. Twelve hips were not operated, with a mean followup of 39 +/- 19.2 months. Pain decreased by more than 80% after cementoplasty in two-thirds of patients, but the mean pain-free interval was only 8.1 +/- 6.6 months (median 5 mo). Nineteen of the 29 working patients were able to transiently return to work. The outcome was more unfavorable with radiological stage III AVN, joint effusion, and/or a double-line sign around the lesions on magnetic resonance images. CONCLUSION: Despite early relief of pain, the results of the cementoplasty technique were disappointing, with need for arthroplasty surgery in most cases within 2 years. Alternative percutaneous techniques using different filler materials with osteoinductive properties should be evaluated in further studies.
