1Hoffa骨折的诊断和治疗进展显示文摘Hoffa骨折是股骨远端冠状面骨折的统称,是罕见的关节内骨折。其多发生于两轮交通工具的碰撞事故,最可能的发生机制为在屈膝状态下,股骨髁的后半部受到冠状面的垂直暴力,并同时遭受前后及内外翻应力的冲击。Hoffa骨折极易漏诊,平片通常难以发现所有的Hoffa骨折,常需要CT矢状面及三维重建协助诊断。其手术入路有髌旁入路、股内侧肌下方入路、直接外侧入路和后外侧入路等。对于不同类型的Hoffa骨折,可选择不同入路以及内植物,以求通过最少的组织剥离获得最可靠的骨折固定。但目前有关Hoffa骨折的治疗多为个案报道,缺乏远期并发症及关节功能的随访研究,对手术入路的选择以及各种内植物生物力学性能的对比也有待进一步研究。谢威 赵航宇 王鑫 李岱洛 付海亮 2021医学综述2021,27,2:3
2Hoffa’s fracture in an adolescent treated with an innovative surgical procedure:A case report显示文摘BACKGROUND Hoffa fracture is rare,especially in adolescents,and has a high rate of complications such as avascular necrosis and osteoarthritis;moreover,there are no definitive guidelines for its treatment.This report could provide a new potential treatment for Hoffa fracture.CASE SUMMARY A 16-year-old girl presented to the orthopedic emergency department of No.2 People’s Hospital of Yibin City with persistent pain following a right knee injury sustained during a sprint race.Her knee was swollen and tender,and the range of motion was restricted by the pain.X-ray and computed tomography revealed a Hoffa fracture in the right knee.After consultation,surgical treatment was performed,and the fracture was fixed with three 3.5-mm cannulated cancellous screws;osteochondral plugs that were harvested from the screw insertion site were re-implanted to cover the screw head.The patient’s fracture and osteochondral plug healed 6 mo postoperatively,and she presented a knee range of motion of 0–135 without pain,and was walking without support with a normal gait.CONCLUSION Here,we describe an innovative surgical procedure for Hoffa fracture that could provide a new possibility for the treatment of similar fractures,and further improve their management.Zu-Xin Jiang Pan Wang Shun-Xin Ye Xiao-Ping Xie Chun-Xiu Wang Yue Wang 2022World Journal of Clinical Cases2022,10,4:1
