Abstract:
Objective:To investigate the clinical effects of antibiotic-loaded calcium sulfate-autologous iliac bone combined with sural neurocutaneous flap in the one-stage treatment of chronic calcaneus osteomyelitis plus skin and soft tissue defects.Methods:From January 2013 to September 2019, 48 patients were admitted to Department of Orthopedic Trauma, Xi'an Honghui Hospital Affiliated to Xi'an Jiaotong University for chronic calcaneal osteomyelitis complicated with skin and soft tissue defects. They were divided into 2 groups according to different bone grafts. In group A of 26 patients treated at one stage by antibiotic-loaded calcium sulfate-autologous iliac bone combined with sural neurocutaneous flap, there were 16 males and 10 females with an age of (45.0±11.7) years and an area of skin defect of (56.0±16.7) cm 2. In group B of 22 patients treated at one stage by simple autologous iliac bone combined with sural neurocutaneous flap, there were 13 males and 9 females with an age of (43.6±9.6) years and an area of skin defect of (53.8±16.2) cm 2. The volume of the ilium harvested, fracture healing time, infection control, donor site complications, pain score of visual analogue scale (VAS) and function recovery of the ankle were compared between the 2 groups. Results:There was no significant difference in the preoperative general data between the 2 groups, showing comparability ( P>0.05). The 48 patients were followed up for (15.3±6.0) months. Group A had a significantly smaller volume of the ilium harvested [(67.3±14.1) cm 3] than group B [(90.7±23.5) cm 3], a significantly lower rate of donor site complications [3.8% (1/26)] than group B [31.8% (7/22)], significantly lower VAS pain scores at 6, 12, 24, 48 and 72 hours than group B, and significantly lower WBC count, erythrocyte sedimentation rate and C-reactive protein at 2, 4, 8 weeks after operation than group B (all P<0.05). There was no statistically significant difference between the 2 groups in the infection control rate [96.2% (25/26) versus 77.3% (17/22)], the fracture healing time [(6.2±1.9) months versus (6.4±2.1) months], or the ankle-hindfoot score of AOFAS (The American Orthopaedic Foot and Ankle Society) (83.9±7.2 versus 82.5±8.7) at 6 months after operation (all P>0.05). Conclusion:In one-stage treatment of chronic calcaneal osteomyelitis complicated with skin and soft tissue defects, compared with simple autologous iliac bone combined with sural neurocutaneous flap, antibiotic-loaded calcium sulfate-autologous iliac bone combined with sural neurocutaneous flap can reduce the volume of the ilium harvested, pain score of VAS, and incidence of donor site complications, and improve the recovery of inflammatory indicators, leading to fine clinical effects.
