Determinants of management outcome in open tibia fractures in ile-ife
Abstract
Background:Fracture of a normal tibia shaft constitutes a major trauma mostly sustained by young adults during high-energy injuries. Its superficial location and the subcutaneous characteristics of its anteromedial aspect easily causes open fracture. The objectives of this study were to determine the pattern of presentation, and determinants of management outcome in open fractures of the tibia.
Methods: This is a prospective hospital based study. A total of 89 patients aged 4 to 80 years with open fractures of the tibia with or without fibula involvement were studied. All the patients received anti tetanus prophylaxis and intravenous antibiotics as well as wound irrigation, debridement and skeletal stabilisation.
Results: Students and traders accounted for the majority of the cases (57.3%). Most of the open tibia fractures 69 (77.5%) had above knee Plaster of Paris cast. The majority of the cases were Gustilo and Anderson type II 32 (36.0%) cases and type I 22(24.7%) cases. There was Correlation between the presence of wound infection and (i) Gustilo and Anderson grading (F -.352, P .001); (ii) Injury to Debridement time in hours (F -.304, P .004); (iii) Osteomyelitis (F .397, P .001); (iv) Delayed union (F .253, P .017); and (v) Union time in weeks (F -.350, P .001). There was also correlation between the following: (i) Injury to Debridement time in hours and the distance from the accident scene to the hospital (F .464, P .001); (ii) The fracture pattern and the union time in weeks (F .353, P .001); and (iii) The presence of osteomyelities and delayed union (F .382, P .001). The commonest complications observed were wound infection 35(39.3%) patients and delayed union 30(33.7%) patients.
Conclusion:This study shows that the higher the Gustilo and Anderson grading of the open fractures of the tibia, the more severe the wound and bone infection that occurred. The interval between injury time and wound débridement time affected the treatment outcome.
