Fractures of the proximal and diaphyseal femur are frequently internally fixed using a fracture table. Moreover, some femoral neck fractures may be treated with total hip arthroplasty using a direct anterior approach and a traction table. Fracture and traction tables both use a boot tightly fitted to the patient's foot in order to: 1) obtain fracture reduction by traction and adequate rotation exerted on the slightly abducted or adducted extremity; or 2) adequately expose the hip joint using traction, rotation and extension to implant total hip arthroplasty components. In some instances, multiply injured patients may present with both a proximal or diaphyseal femur fracture and a diaphyseal or distal tibia or ankle fracture necessitating an ankle spanning external fixator on the same limb. Frequently, the tibia or ankle fracture has to be treated first, and standard use of the fracture or traction table may be thereafter difficult due to the external fixator construct preventing tight fitting of the boot to the patient's foot.
In order to address this situation, the authors describe a simple technique allowing rigid fixation of the limb with an ankle spanning external fixator to the traction or fracture table, providing accurate control of the position of the lower limb in all planes for adequate fracture reduction and fixation or total hip arthroplasty. The technique is exemplified with a clinical case.
This technique allows an efficient way to: 1) timely stabilize diaphyseal or distal tibia or ankle fractures; and 2) subsequently use all the advantages of a fracture or traction table to adequately reduce and fix proximal or diaphyseal femur fractures, or optimally expose femoral neck fractures for total hip arthroplasty using a direct anterior approach.
股骨近端和骨干骨折常采用骨折复位固定床进行内固定。此外,一些股骨颈骨折可采用直接前路和牵引复位床行全髋关节置换术治疗。骨折复位固定床和牵引复位床均使用靴形固定器将患者的足部紧紧固定,以:1)通过牵引和对轻度外展或内收肢体施加的适当旋转获得骨折复位;或 2)通过牵引、旋转和伸展充分暴露髋关节,以植入全髋关节置换组件。在某些情况下,多发伤患者可能同时存在股骨近端或骨干骨折以及骨干或远端胫骨或踝关节骨折,需要在同一肢体上使用踝关节跨越式外固定器。通常,胫骨或踝关节骨折需要首先进行治疗,由于外固定器结构阻止靴形固定器与患者足部紧密贴合,因此标准使用骨折复位固定床或牵引复位床可能会变得困难。
为了解决这个问题,作者描述了一种简单的技术,可将带有踝关节跨越式外固定器的肢体刚性固定到牵引复位床或骨折复位固定床,以便在所有平面上精确控制下肢的位置,从而充分实现骨折复位和固定或全髋关节置换术。该技术通过一个临床病例进行了说明。
该技术可有效地实现:1)及时稳定骨干或远端胫骨或踝关节骨折;2)随后充分利用骨折复位固定床或牵引复位床的所有优势,充分复位和固定股骨近端或骨干骨折,或在直接前路行全髋关节置换术时最佳暴露股骨颈骨折。
