We hypothesized that less malalignment and complications occur with intramedullary nailing of distal third tibia fractures (42A, B, C) after the implementation of orthopedic trauma surgeons to this level II community hospital. We also hypothesized that patients with < or =5 degrees of malalignment have poorer function as measured by the MODEMS functional outcome scale. Two cohorts of distal third tibia fractures were identified by discharge diagnosis or by the Orthopaedic Trauma Association database. Group I (n = 39) patients were stabilized with an intramedullary nail by community orthopedic surgeons. Group II (n = 18) patients were treated by orthopedic trauma surgeons. In Group I (community), 9 (23%) patients treated by the community surgeons exhibited >5 degrees of angulation in at least one direction. Five (13%) of these patients displayed angulation in more than one direction, and 3 of these patients exhibited >10 degrees of angulation. In Group II (trauma) 1 (5%) patient had >5 degrees angulation in any plane (P < .05). No differences were noted in time to union, nonunion, delayed union, hardware failure or infections between the two groups. Functional outcomes were assessed using the MODEMS lower limb module. In comparison of the patients with and without significant angulation, the P value for bodily pain was 0.042. Patients treated by the community orthopedic surgeons had a higher incidence of malalignment, as compared to those treated by orthopedic trauma specialists.
我们假设,在这家二级社区医院引入骨科创伤外科医生后,对胫骨干骺端骨折(42A、B、C型)进行髓内钉固定时,畸形和并发症会减少。我们还假设,根据MODEMS功能结果量表测量,畸形≤5度的患者功能较差。通过出院诊断或骨科创伤协会数据库确定了两组胫骨干骺端骨折患者。第一组(n = 39)患者由社区骨科医生用髓内钉固定。第二组(n = 18)患者由骨科创伤外科医生治疗。在第一组(社区组)中,社区医生治疗的9名(23%)患者至少在一个方向上出现>5度的成角。其中5名(13%)患者在多个方向上出现成角,3名患者出现>10度的成角。在第二组(创伤组)中,1名(5%)患者在任何平面上出现>5度的成角(P < 0.05)。两组在愈合时间、骨不连、延迟愈合、内固定失败或感染方面均未发现差异。使用MODEMS下肢模块评估功能结果。在有明显成角和无明显成角的患者比较中,身体疼痛的P值为0.042。与骨科创伤专科医生治疗的患者相比,社区骨科医生治疗的患者畸形发生率更高。
