Abstract
Introduction
Primary wound closure in open tibial fractures has not been recommended. Traditionally initial debridement with fracture stabilisation and delayed wound closure was the accepted treatment. However this practice was developed before the use of prophylactic intravenous antibiotics and improved techniques for fracture stabilisation. Studies suggest that infections are not caused by the initial contamination but the organisms acquired in the hospital. Subsequent primary wound closure after adequate wound care and fracture stabilisation should be a safe concept and should not increase the rate of complications.
Material/methods
In a retrospective study we analysed 95 patients with open tibial fractures Gustilo-Anderson Type 1-3a treated at two different teaching hospitals with primary fracture stabilisation and delayed wound closure as group I and primary fracture stabilisation and primary wound closure as group II. Exclusion criteria to the study were the following conditions: Grade 3b and 3c fractures, polytrauma, other fractures, significant medical history, previous surgery 6 months prior to admission. In group I 46 patients (38 males, 8 females) with a mean age of 30.2 years (16-56) were included. 19 sustained Grade 1 open, 16 Grade 2 open, 4 Grade 3a open and 7 gunshot fractures to the shaft of the tibia. In group II 49 patients (36 males, 13 females) with a mean age of 33.4 (18-69) were included. 19 sustained Grade 1 open, 19 Grade 2 open, 3 Grade 3a open and 8 gunshot fractures. The mean follow-up in group 1 was 11.5 (9-18) and 11.7 (8-16) months. The criteria for post-operative infection were clinical/radiological.
Results
The mean operating time in group 1 was 96 (45-180) minutes, in group II 101 (40-170) minutes. The hospital stay in group 1 was 8.6 (3-20) days and in group 2 15.4 (4-52) days. One infectious case in group 1 was seen (2%) and two cases in group 2 (4.3%) were found. On further analysis one case in group 2 in our opinion should not have been treated with primary fixation and wound closure. He only had 3 doses of a first generation cephalosporin and was operated 20 hrs after admission to hospital. The corrected sepsis rate in group 2 should therefore should be calculated without that case and then is 2.1%.
Discussion
Our results support recent findings that primary wound closure after thorough debridement in Grade 1+2 open fractures does not increase the infection rate in comparison to the standard treatment. It shortens hospital stay and is cost effective treatment. We conclude that primary wound closure is safe. Prospective multicentre studies are needed to further evaluate and result in change of the current practice.
