Abstract:
Objective:To investigate the clinical efficacy of induced membrane technique in the staged treatment of adult chronic hematogenous osteomyelitis (CHOM) of long bone.Methods:The clinical data were retrospectively analyzed of the 22 adult patients with CHOM of long bone who had been admitted to the 920th Hospital, Joint Logistics Support Force of PLA from January 2016 to December 2019. There were 18 males and 4 females, aged from 16 to 56 years (average, 31.81 years). Their disease duration ranged from 0.6 to 42.0 years, averaging 18.4 years. By the Cierny-Mader anatomical classification, 4 cases were type Ⅰ, 6 cases Type Ⅲ, and 12 cases type Ⅳ. In the first stage, the bone defects were filled with antibiotic bone cement after thorough debridement. In the second stage when the infection had been controlled, the bone defects were repaired with bone grafts after removal of the bone cement. Bone healing time and complications were followed up. The treatment effects were evaluated by comparisons of the infection control indexes [including clinical manifestations like local redness, swelling, pus, and pain, and blood white blood cell count, C-Reactive protein (CRP), and erythrocyte sedimentation rate (ESR) as well] before the primary surgery, before the secondary surgery and at the last follow-up.Results:The volumes of the bone defects after stage-one debridement ranged from 54 cm 3 to 176 cm 3 (mean, 90.9 cm 3). All patients were followed up for 20 to 51 months (mean, 30.1 months) after surgery. All bone defects healed after 4 to 11 months (mean, 6.6 months). Postoperatively, infection developed at the bone extraction site of the posterior superior iliac spine in 3 cases and pain was observed at the donor site in one case, but the conditions were relieved after symptomatic treatment. Fracture and plate breakage occurred at the bone defect site in one case who had fallen down 7 months after operation, but responded to reoperation. The last follow-up revealed such symptoms as redness, swelling and pus discharge in none of the patients. The white blood cell count [(5.70 ± 1.57) × 10 9/L and (5.65 ± 1.58) × 10 9/L], CRP [(7.56 ± 2.57) mg/L and (7.25 ± 3.83) mg/L] and ESR [(9.64 ± 2.90) mm/h and (10.55 ± 5.23) mm/h] before the secondary surgery and at the last follow-up were significantly lower than those before the primary surgery [(8.24 ± 2.18) × 10 9/L, (49.54 ± 19.56) mg/L, and (42.68 ± 13.77) mm/h] (all P < 0.05). However, there were no significant differences between the indexes before the secondary surgery and at the last follow-up ( P > 0.05). Conclusion:In the staged treatment of adult CHOM of long bone, the induced membrane technique can effectively control infection, achieve repair of bone defects, and reduce complications.
