Treatment of chronic osteomyelitis with one-stage allograft

<正>Objective: To avoid disadvantages of two-stage cancellus bone autograft, we investigated the feasibility of one-stage allograft for reconstructing the bone defect resulting from debridement of chronic osteomyelitis in limbs. Methods: Between Feb. 1999 and Apr. 2004, 35 cases of chronic osteomyelitis ( 8 cases of nonunion) underwent one-stage allograft after debridement in our hospital. Results: Thirty-five cases were followed up for an average period of 28 months (range, 13 to 55 months), in which 32 cases (91.43%) were found no infection, and 3 cases (8.57%) were confirmed recurrence of infection. Four out of 8 cases of bone nonunion healed in 9.5 months on average (range, 3 to 12 months), and another case also acquired union after redebridement and autograft of ilium due to infection recurrence 35 days after surgery. Renonunion occurred in 3 cases, 2 out of whom healed after secondary operation with autograft. One case of renonunion and 2 cases of infection recurrence refused further treatment. Conclusions: A high rate of infection arrest can be attained when one-stage allograft is used to reconstruct the bone defect of chronic osteomyelitis after debridement in limbs. Therefore, chronic osteomyelitis should not be regarded as a contraindication to one-stage aliogeneic bone grafting. Renonuion, however, achieves a relatively high rate, especially in cases of segmental bone defect.
