Avulsión de la tuberosidad tibial anterior combinada con desinserción del tendón rotuliano en paciente con fisis abierta. Resolución quirúrgica. Reporte de un caso

Abstract

Introduction: avulsion of the anterior tuberosity of the tibia represents <1% of physeal injuries in the pediatric population, while patellar tendon ruptures are even more infrequent. In turn, the combination of both is a rare lesion with few reports in the bibliography.

Case: the case of a 15-year-old patient with open physis, with a combined lesion of the extensor mechanism is reported. Its surgical resolution and postoperative management are detailed based on the current bibliography.

Discussion: there is little precise information on the incidence, diagnosis and prognosis of this lesion. Recent works describe an increase in its incidence and propose a new classification that allows better management of this serious injury early.

Conclusion: combined extensor mechanism injuries are increasing in the skeletally immature population due to greater participation in competitive sports at increasingly younger ages. Currently there is no consensus on its diagnosis. Magnetic resonance imaging is proposed as the method of choice because it detects associated lesions and allows planning the surgical strategy.
