ABSTRACT
Objective:To analyze the therapeutic effect of sural neurocutaneous flap combined with antibiotic-impregnated calcium sulfate and autogenous iliac bone graft of chronic calcaneal osteomyelitis.Methods:A retrospective analysis was peformed in 29 patients with chronic calcaneal osteomyelitis treated with sural neurocutaneous flap combined with antibiotic-impregnated calcium sulfate and autogenous iliac bone graft in the Xi′an Honghui Hospital Affiliated to Xi′an Jiaotong University from April 2013 to January 2020. There were 19 males and 10 females, with the age of (45.38±12.85) years, ranged from 22 to 67 years. The course of disease was (16.00±6.96) months, ranged from 6 to 36 months. The skin defect area was (41.9±15.9) cm 2, ranged from 11.8 to 86.8 cm 2. The causes of injury: 18 cases of high fall, 6 cases of traffic accidents, 3 cases of heavy rolling, the remaining 2 cases were machine strangulation and sharp stab wounds. The inflammatory markers [white blood cell (WBC), erythrocyte sedimentation rate (ESR), procalcitonin (PCT), C reactive protein (CRP)] and bone healing time were recorded before operation, 2, 4, 8 weeks and 6 months after operation. During the follow-up period, the flap texture, survival were observed, and the ankle-posterior foot function recovery was evaluated by the American Association of Foot and Ankle Surgery (AOFAS) score were observed before and after the operation, and the incidence of complications were recorded. The measurement data were expressed as mean±standard deviation ( ± s), and the t-test was used for inter-group comparison; the levels of WBC, ESR, PCT and CRP at different time points before and after operation were compared by repeated measurement ANOVA, and the LSD t-test was used for pairwise comparison. Results:All the 29 patients were followed up for (14.51±6.10) months, ranged from 6 to 30 months. All the flaps survived without abrasion, ulceration, or skin protrusion, and all patients could walk normally with shoes. There were 28 cases of stage I bone healing, with an average of (5.87±2.07) months, ranged from 3 to 12 months. The inflammatory indexes was significantly decreased at different time points after operation ( P<0.05). There was no significant difference between 6 months and 8 weeks after operation ( P>0.05), while there was significant difference at other time points ( P<0.05). The ankle-posterior foot score of AOFAS at 6 months after treatment was significantly higher than that before treatment (83.44±7.93 vs 55.37±8.07), the differences was statistically significant ( P<0.05). The clinical efficacy of foot function recovery was excellent in 12 cases, good in 15 cases and fair in 2 cases among 29 patients .The excellent and good rate was 93.1% (27/29). One patient recurred 1 month after operation and was re-implanted with antibiotic-loaded calcium sulfate mixed autogenous iliac bone after debridement, no recurrence was found. The total complication rate was 31.0%, but there was no significant impact on the patient's life in the later period. All patients returned to daily life and work. Conclusion:The treatment of chronic calcaneal osteomyelitis with sural neurocutaneous flap combined with antibiotic-impregnated calcium sulfate and autogenous iliac bone graft can effectively control infection, reconstruct calcaneal and soft tissue structure, promote functional recovery of affected limb, and ultimately improve the patient′s quality of life.
