[Long-term results of treatment including creation of a gutter and muscle transposition for chronic sclerosing osteomyelitis].

OBJECTIVES

We evaluated long-term results of treatment including creation of a gutter and muscle transposition in patients with chronic sclerosing osteomyelitis (CSO).

METHODS

Between 1980 and 1996, 11 patients (5 women, 6 men; mean age 36 years; range 17 to 69 years) with CSO were treated with creation of a gutter and muscle transposition. Seven patients had femoral, and four patients had tibial involvement. The main complaint was pain. The patients were evaluated with respect to complaints and radiologically (X-ray, computed tomography, and magnetic resonance imaging) after a mean follow-up of 12.4 years (range 6 to 24 years).

RESULTS

During the follow up period, all the patients remained symptom-free without the need for antibiotic treatment except for one patient with tibial involvement, whose pain recurred after five years. The patient's complaint disappeared following reoperation with the same technique. Histologic examination of surgical biopsies showed nonspecific changes consistent with low-grade chronic osteomyelitis. Cultures were negative in all cases. Control radiographies showed no progression of sclerosis. Computed tomography showed cortical bone formation surrounding the transposed muscle, and magnetic resonance imaging showed fatty degeneration in the transposed muscle, without any signs of active osteomyelitis.

CONCLUSION

The aim of gutter creation and muscle transposition is to increase blood supply to the diseased bone segment, without the need for microsurgical interventions and secondary reconstructive procedures. Our long-term results show that this technique is efficacious in patients with femoral and tibial involvement.
