ABSTRACT
@#Tibial tuberosity avulsion fracture is a rare injury, and bilateral occurrence is more uncommon. Periosteal sleeve fracture is a unique fracture pattern which was first described in the lower pole of patella in children. We are reporting a rare case of bilateral tibial tuberosity sleeve fracture in a teenage boy which occurred while sprinting. The patient underwent open reduction, pull through suture fixation of the bilateral tibial tuberosity and screw fixation of left tibial tuberosity. Post-operative rehabilitation included gradual increment of range of motion with hinged brace and quadriceps muscle strengthening. Close follow-up was done to monitor the progression of his recovery. At six months follow-up, the patient recovered well. Both knees had full range of motion with an intact extensor mechanism.
ABSTRACT
Avulsion fractures of the anterior tibial tubercle are uncommon, occurring mainly in male sporting adolescents. We report four cases of acute tibial tubercle fractures. The fractures occurred in two patients after falling on their knees, a third patient presented a quadriceps contraction and in the remaining case suffered a direct blow to the knee. Acording to Ogdens classification the fractures were stage IIA, IIB, IIIA and IIIB. In all cases treatment was open reduction and internal fixation with good results.
Las fracturas por avulsión de la tuberosidad anterior de la tibia son infrecuentes, ocurriendo principalmente en adolescentes varones durante la práctica deportiva. Se presentan cuatro casos de fracturas de la tuberosidad tibial anterior. El mecanismo de la lesión en 2 de los casos correspondió a una caída a nivel asociada a golpe de ambas rodillas, un tercer paciente presentó una contracción excéntrica del cuadriceps y en el caso restante sufrió un golpe directo en la rodilla. Las fracturas corresponden a los tipos IIA, IIB IIIA y IIIB según la clasificación de Ogden. En todos los casos el tratamiento fue reducción abierta y fijación interna con tornillos, con buenos resultados.
