Abstract Unstable pelvic ring injuries and open book injuries remain a clinical challenge to be efficiently and promptly managed. Traumatic disruptions of the pelvic ring result in an injury of varying degree to the bony pelvis, and its soft tissue envelop. Various nerve, vessel, and visceral structures may be damaged. The aim of this study is to evaluate the results of management of open book fractures with single symphseal plating versus double plating. This work was carried out in Department of Orthopaedics and Traumatology of Menofia University Hospital. It included 20 cases with open book injuries. The age of the patient ranged from 34 to 70 years with a mean 54.55 years. Road traffic accidents were responsible for the majority of cases. Males were more commonly affected than females with a ratio of approximately 2:1. Most patients were presented with open book fractures as a part of polytrauma to different body regions. The commonest associated injuries were located in the muskuloskeletal system. The lower extremities were more affected than the upper extremities, femoral fractures were the commonest. Urological injuries were recorded in 2 cases (10%), abdominal injuries were reported in 3 cases (15%), head injuries were reported in 3 cases (15%) and chest injuries were reported in 2 cases (10%). The pelvic fractures were type B3.1 according to modified Tile (1995) classification; According to the Young and Burgess classification system, most of the patients were of anteroposterior injury (APC) type APC(I) 9 cases (45%),type APC(II) 9cases (45%) and APC(III) 2 cases(10%). All the patients were treated by active resuscitation according to the guidelines of the Advanced Trauma Life Support protocol, with priority to cardiopulnionary conditions. At the same time primary and secondary surveys were carried out to rule out any life-threatening condition, and to evaluate the patient generally. After resuscitation, all patients underwent meticulous clinical examination and routine radiological views of the pelvis included anteroposterior, inlet, and outlet views, in addition to C.T scanning were taken. Emergent pelvic binder was done as a part of primary resuscitation for cases with haemodynamic and mechanical instability. Open reduction and internal fixation were used in all 20 patients (100%). Nine cases were fixed anteriorly with single plate, 11 cases were fixed anteriorly with double plate. For most cases, partial weight-bearing was started after 3 weeks and progressed gradually to full weight-bearing after 6- 8 weeks guided by radiological healing. The presence of lower limb fractures caused delay of weight-bearing in some cases. Reduction to within 10 mm seems to be adequate for functional results. This may be because the pelvis exhibits only structural properties with weight bearing and sitting as opposed to joint in which arthritis may ensue in a short time if there is no anatomic reduction. Early complications include : Infection occurred in 4 cases (20%); three had deep wound infection. The fourth was superficial wound infection. Deep vein thrombosis occurred in one patient (5%). Loss of reduction occurred in 3 cases (15%) and was more common after type APC(II) fracture. Posterior displacement more than 10mm was reported in 3 cases. Nonunion occurred in one patient (5%). Implant loosening occurred in 2 patients (10%), screw misplacement in one case (5%) and drill bit breakage in on case (5%) Majeed et al., (1990) grading scale were used and the results was unsatisfactory (Fair+poor) in 7 cases (35%) and satisfactory (excellent +good) in 13 cases (65%). The presence of associated injuries can have profound deleterious effects on the final outcome of patients with pelvic fractures. |
