Abstract/OtherAbstract:
OBJECTIVE: Minimally invasive stabilization of the posterior pelvic ring in type C injuries. INDICATIONS: Unstable type C injuries of the pelvic ring, uni- or bilateral. - Transsymphyseal-transsacral instability. - Transpubic-transsacral instability. - Transsymphyseal-transsacroiliac instability. - Transpubic-transsacroiliac instability. CONTRAINDICATIONS: Fractures in childhood. Comminuted fractures of the ilium. Patients with skin and soft tissues in a poor condition and/or local infection. Sacral fractures with a neurologic deficit are not a contraindication because they can be decompressed by distraction and stabilized in a neutral position by plate fixation. SURGICAL TECHNIQUE: Nut-shaped osteotomy of the posterior superior iliac spine bilaterally through two short, vertical skin incisions. Tunneling through the muscles of the back to the opposite side. Length measurement for a 4.5-mm pelvic reconstruction plate. The plate is bent by about 70 degrees over the fourth lateral hole. Slide-insertion of the plate and bending of the free plate end for close fit. Cancellous bone screws are inserted into the plate holes. Refixation of the osteotomized bone fragments over the plate with small-fragment, cancellous bone screws. RESULTS: 34 patients with an average age of 42.6 years were treated according to the described method from 1998 to 2005; 18 were polytraumatized. The anterior pelvic ring was also stabilized by surgery in 28 patients for eleven of whom it was the first intervention in a two-stage procedure. 25 patients were available for clinical and radiologic follow-up at 17 months, on average. The plain radiographs after 1 year showed a very good outcome in 16 patients (maximal displacement of the posterior pelvic ring < 5 mm) and a good outcome in eight patients (displacement of 5-10 mm). In two patients there was loss of reduction in the 1st postoperative year despite a very good reduction result immediately postoperatively (dislocation < 5 mm), whereby the dislocation for one patient was < 10 mm on the final radiograph and 19 mm for the other. One patient presented with a late infection 11 weeks postoperatively that healed after implant removal and wound debridement. In two other patients, prominent screw heads, which were used for refixation of the osteotomized posterior superior iliac spine, had to be removed under local anesthesia in the 10th postoperative week. The further course for these two patients was uneventful. In one patient the implants were retrieved in the 5th postoperative month because the patient complained of internal hot and cold sensations although the soft tissue was not irritated. The plates were removed in six other cases after the fracture/instability had healed, i. e., after 9-12 months, on average; in all other cases the implants were left in situ.
