Abstract
Introduction
Management of open fractures is challenging and requires a multidisciplinary team approach. Gustilo Anderson Type IIIB fractures reportedly have a higher infection rate (up to 52%) and up to 16% amputation rate. This study aims to evaluate outcomes of using Adjuvant Local Antibiotic Hydroxyapatite Bio-Composite in management of Open Gustilo-Anderson IIIB fractures.
Materials and Methods
We reviewed a prospective data of 80 patients who presented with Gustilo Anderson Type IIIB Open Fracture to a single ortho-plastic centre. Only patients who were managed with single-stage “Fix and Flap” along with intra-operative Adjuvant Local Antibiotic Bio-Composite were included.
Results
Mean follow-up time was 22 months. The mean time from injury until definitive surgery was 7.73 days (1–30 days). Primary union achieved in 88.3% within 32 weeks on average. The delayed union reported in 7.8% of patients, for the bone healing stimulated by injecting the fracture site with Autologous Bone Marrow Aspirate Concentrate. Subsequent follow-up showed signs of successful fracture healing at 60 weeks post-injury. Three patients (3.9%) had non-union. Limb salvage rate was 96.25%, and only 1.25% deep infection rate.
Conclusions
Our results highlight that low infection rates, high limb salvage rates and high union rates can be achieved in these complex injuries with a combined OrthoPlastic approach, MDT input, meticulous technique and the use of adjuvant local antibiotic bio-composite. Delay in definitive surgery, gentamicin resistance and smoking were not associated with any increased deep infection or non-union in our series. At 22 months of follow-up, deep infection rate was 1.25%, limbs salvage rate was 96.25%, fracture union rate was 96.1%, and reoperation rate 18.75%.
