Estudo das fraturas peritrocanterianas instáveis do fêmur tratadas com haste céfalo-diafisária bloqueada: técnica minimamente invasiva Study of femur unstable peritrochanteric fractures treated with blocked cephalodiaphyseal shaft: a minimally invasive technique
Abstract
Sessenta e cinco pacientes com fraturas peritrocanterianas instáveis foram tratados cirurgicamente com fixação intramedular céfalo-diafisária bloqueada (sistema minimamente invasivo). Realizou-se redução fechada em mesa de tração com utilização da radioscopia. Carga parcial assistida foi encorajada a partir do segundo dia pós-operatório. Em todos os pacientes estudados, foi obtida consolidação entre 12 e 18 semanas (média de 14.5 semanas), sendo observados seis casos (9,2%) de consolidação viciosa, quatro (6,1%) de encurtamento do membro (Sixty five patients with unstable peritrochanteric fractures were surgically treated with blocked intramedullary cephalodiaphyseal fixation (minimally invasive system). Closed reduction in traction table was performed with radioscopy. Assisted partial load was encouraged after the second postoperative day. In all examined patients, healing was achieved within 12 to 18 weeks (average 14.5 weeks). Complications were seen in six cases (9.2%) with vicious union, four cases (6.1%) with shortening of the limb (<1cm), three cases (4.6%) with compression screw migration to acetabulum, and one case (1.5%) with intraoperative fracture of the lateral femur cortical. Five patients (7.6%) presented with distal deep venous thrombosis (DVT) with no clinical repercussion. No superficial or deep infection was seen up to the last review. In the three cases of proximal migration of the compression screw, system was removed without intercurrences. We concluded that the methodology employed here is efficient, safe, with low morbidity potential. It is a fast technique, presenting little complications, promoting an early rehabilitation for the patient.
