Orthosorb resorption evaluation using MRI and histologic analysis.

Resorbable bone fixation devices may be used in various surgical procedures for internal fixation in place of traditional metallic devices. Currently, there is no radiographic technique for tracing the postsurgical location and resorption of these devices. This study was undertaken to ascertain whether magnetic resonance imaging is a suitable tool for performing such evaluations. Using an animal model, the authors investigated the correlation over time between the magnetic resonance image of a surgically implanted pin and its histologically verified location and state.

MRI evaluation of Orthosorb pin insertion for surgical treatment of hallux abducto valgus.

This preliminary study considers the advantage of magnetic resonance imaging over plain film radiography in assessing pin resorption and bone marrow regeneration over a 6-month period. The Orthosorb pin was used to fixate an Austin osteotomy in a patient and was followed with serial magnetic resonance imaging at scheduled intervals. This study expands on the preceding study in this issue of the Journal, which was carried out in the rat model.

Dermatofibrosarcoma protuberans: 4 years after local trauma.

Dermatofibrosarcoma protuberans (DFSP) is a low grade, fibrohistiocytic malignant soft tissue tumor that arises infrequently in the foot and ankle region. It most frequently demonstrates a "storiform" histologic pattern, and if incompletely excised, may be recurrent, more anaplastic and metastatic. Soft tissue plain film radiography, as well as magnetic resonance imaging (MRI) help outline the tumor and involved tissues, which is beneficial in staging, determining surgical approach and evaluation of therapy. Definitive diagnosis is made by biopsy. A dermatofibrosarcoma protuberans is reported in the foot of a 14-year-old female patient, 4 years after trauma to the site.
