Abstract

Introduction: Dynamic interaction of cam and pincer deformities can result in pathological contact forces in femoroacetabular impingement (FAI) syndrome. Similar deformities were noted during acetabular fracture reconstruction. We hypothesise that the prevalence of FAI deformity is higher in patients sustaining acetabular fractures than in a control group.

Methods: This retrospective radiographic study compared the parameters that define FAI deformity in 100 patients consecutively admitted to a trauma unit with an acetabular fracture and a control group of 100 patients with lateral compression pelvic fracture without acetabular injury. Both underwent identical clinical imaging. Centre-edge angles (CEA) and alpha angles were used to define patients with pincer, cam, or mixed FAI deformity.

Results: There were significantly more patients with FAI deformity in the acetabular fracture group than in the control group (71% vs. 18%, p < 0.0001). There were considerably more fractures involving both anterior and posterior acetabular columns in patients with 'pincer' sockets (p = 0.02, OR = 2.95, 95% CI, 1.12-7.78).

Conclusions: There is a high prevalence of cam and pincer deformities in patients with acetabular fractures, particularly bi-column fractures.

双柱髋臼骨折中股骨髋臼撞击畸形的高发率。

导言：凸轮和钳形畸形的动态相互作用可导致股骨髋臼撞击（FAI）综合征的病理性接触力。在髋臼骨折重建过程中也发现了类似的畸形。我们假设，髋臼骨折患者的 FAI 畸形发生率高于对照组：这项回顾性放射学研究比较了连续入住创伤科的 100 名髋臼骨折患者和对照组 100 名无髋臼损伤的骨盆侧向压缩性骨折患者中定义 FAI 畸形的参数。两组患者均接受了相同的临床影像学检查。中心边缘角（CEA）和α角用于界定钳形、凸形或混合型FAI畸形患者：结果：髋臼骨折组的 FAI 畸形患者明显多于对照组（71% 对 18%，P = 0.02，OR = 2.95，95% CI，1.12-7.78）：髋臼骨折患者，尤其是双柱骨折患者，凸轮和钳形畸形的发生率很高。

期刊介绍： HIP International is the official journal of the European Hip Society. It is the only international, peer-reviewed, bi-monthly journal dedicated to diseases of the hip. HIP International considers contributions relating to hip surgery, traumatology of the hip, prosthetic surgery, biomechanics, and basic sciences relating to the hip. HIP International invites reviews from leading specialists with the aim of informing its readers of current evidence-based best practice. The journal also publishes supplements containing proceedings of symposia, special meetings or articles of special educational merit. HIP International is divided into six independent sections led by editors of the highest scientific merit. These sections are: • Biomaterials • Biomechanics • Conservative Hip Surgery • Paediatrics • Primary and Revision Hip Arthroplasty • Traumatology
