Treatment of unstable sacral fractures with percutaneous reconstruction plate internal fixation

Abstract

To study the effects of percutaneous reconstruction plate internal fixation in the treatment of unstable sacral fractures. Percutaneous reconstruction plate internal fixation was applied on 21 cases of unstable sacral fracture (15 males and six females, at age range of 16-65 years, mean 38.3 years) including four cases of Denis Zone I, 14 cases of Zone II and three cases of Zone III. In operation, an arc incision (about 3-5 cm long) was made along the iliac crest on the outside border of posterior superior iliac spine (PSIS) on both sides, and then the plate was transported from the wounded side to the opposite one through the subcutaneous tunnel. The mean incision length, operation time, intraoperative blood loss was 4.3 cm, 45.2 min, and 160.8 ml respectively. All these patients were followed up for 12-33 months (average 16.3 months), which showed no incision infection, intraoperative neurovascular injury, internal fixation loose or breakage, disunion, or obvious lower limb length inequality. The function result was rated as excellent in six cases, good in 12 and fair in 3, with excellence rate of 85.7%, according to the Majeed scoring system. Percutaneous reconstruction plate internal fixation is an ideal surgical approach to unstable sacral fractures, as it is easy, safe, causing less trauma and fewer complications, and conducive to quicker recovery.
