title: Resection of large tumors of the anterior pelvic ring while preserving functional stability of the hip.
abstract: Periacetabular tumors of the anterior pelvic ring often present difficult problems in diagnosis and treatment. The use of computed tomography is valuable. In cases of unquestionable malignancy, hemipelvectomy is the generally accepted treatment. In pelvic tumors of low grade or questionable malignancy, a local wide resection is indicated. Total acetabulectomy results in an unstable hip with marked leg shortening. Transacetabular anterior pelvic ring resection is recommended to preserve the superior part of the acetabular fossa. This procedure is illustrated in two men, 26 and 30 years of age, presenting with low or questionable malignancies.
