Vascular complications of tibial exostosis: A case of popliteal vein thrombosis.

Tibial exostosis, also known as osteochondroma, is a common benign bone tumor found predominantly in adolescents and young adults. Vascular complications associated with this tumor, such as arterial occlusion and pseudoaneurysm formation, are rare but can lead to significant morbidity if not promptly diagnosed and managed. We present a case of a 25-year-old patient who presented with thrombosis of the left popliteal vein and a painless swelling in the popliteal fossa. Radiographic and CT angiography revealed an exostosis on the proximal tibia causing arterial occlusion and venous compression. Surgical resection of the exostosis via a posterior knee approach resulted in successful resolution of symptoms and a favorable outcome at a 12-month follow-up. Histopathological examination confirmed the benign nature of the tumor with no evidence of malignant transformation. This case highlights the importance of prompt recognition and surgical intervention in managing vascular complications associated with tibial exostosis. A multidisciplinary approach involving orthopedic and vascular specialists is crucial for achieving optimal outcomes in such cases.

Delayed slipped capital femoral epiphysis after orif for subtrochanteric femur fracture.

INTRODUCTION AND IMPORTANCE: Slipped capital femoral epiphysis (SCFE) is a common phenomenon of the proximal femur in adolescents with an unclear etiology. It is more common in boys than girls and there does seem to be some predilection to race, weight, and age (Lehmann et al., 2006 [7]). CASE PRESENTATION: We reported a 13-year-old boy who presented with unilateral SCFE following subtrochanteric left femur fracture, which was fixed by blade plate 6 monthes before the SCFE. The SCFE fixed by two cannulated screw. We aim to discuss the possible link between the surgical technique used for proximal femur fractures and the delayed onset of SCFE. CLINICAL DISCUSSION: Slipped capital femoral epiphysis (SCFE) after treatment of subtrochanteric fracture can be caused by inadequate treatment of the fracture. Orthopedic surgeons should be aware of this complication so that they can promptly recognize this complication and treat it urgently (Chinoy et al., 2020). CONCLUSION: Slipped capital femoral epiphysis (SCFE) after treatment of subtrochanteric fracture is a very rare condition, that it can be prevented by proper reduction and fixation of the fracture using appropriate osteosynthesis material.
