吸収性材料を移植骨固定に用いた臼蓋形成術 (Spitzy変法) の術後短期成績

We evaluated the long-term results of a modified Spitzy shelf operation for secondary osteoarthritis in 119 hips with a mean follow-up of 23.8 years. The mean age of the patients at the time of surgery was 25 years. Preoperative osteoarthritic change, the age at operation and shelf height were important factors in determining the outcome. Of the 61 hips in the pre-stage (three) and the initial stage (58) of osteoarthritis, 53 (87%) had good results, compared with only 30 (51%) of 58 hips with advanced osteoarthritis. Of the latter, 72% of those aged less than 25 years had good results compared with only 40% of patients aged over 25 years. The shelf height in the group with good results was significantly lower than in those with poor results. This operation is a safe procedure and indicated for acetabular dysplasia or subluxation of the hip with early osteoarthritic change in patients aged less than 25 years.

The modified Spitzy shelf operation for patients with dysplasia of the hip. A 24-year follow-up study.

Since 1961 we have used the Spitzy shelf operation combined with a vertical flap osteotomy of the outer cortex of the ilium for early arthrosis secondary to acetabular dysplasia, subluxation, and dislocation. In 124 hips, followed for 10 (5-25) years, clinical improvement was maintained in 67/85 of patients who were operated on under the age of 30 and in 22/39 of patients treated after 30. However, less than half of the hips in the younger group and only one out of ten in the older group were symptom-free.
