Intertrochanteric femur fractures are very common in patients over 65 years old, and are often associated with osteoporosis. Proximal femoral nails are preferred because of their biomechanical advantages in the treatment of these fractures, especially if the fracture is unstable. However, many complications associated with intramedullary fracture fixation have been described. The medial migration of the intramedullary gamma nail is a rare complication. The authors report an uncommon but potentially fatal complication, medial and intrapelvic migration of the intramedullary Gamma 3 nails, recorded after one month of osteosynthesis. This article aims to alert the orthopedic community to this rare complication, which may present a high risk of morbidity and mortality.
股骨粗隆间骨折在65岁以上患者中非常常见,且常与骨质疏松相关。由于股骨近端髓内钉在治疗这些骨折方面具有生物力学优势,尤其是在骨折不稳定的情况下,因此被优先选用。然而,已有许多与髓内骨折固定相关的并发症被描述。髓内γ钉的内侧移位是一种罕见的并发症。作者报告了一种不常见但可能致命的并发症,即髓内Gamma 3钉在骨合成一个月后出现内侧及盆腔内移位。本文旨在提醒骨科界注意这种罕见并发症,其可能带来较高的发病和死亡风险。
