Interlocking nailing is a well-established procedure for managing unstable tibial shaft fractures. Closed reduction and internal fixation of the tibial shaft fractures require ease of intraoperative positioning, maneuvering, and biplane imaging. We describe the use of an innovative modular tibia-nailing stand, which greatly enhances the ergonomics of the tibia nailing procedure.
Closed tibia nailing is a popular, established, and commonly performed operative procedure for the treatment of tibial shaft fractures [1]. For improved outcomes, optimum fracture alignment and rotational correction play an important role [2]. Intraoperative fracture alignment is usually obtained by applying traction along the long axis of the leg manually or by distractor assistance. Final reduction and nail position depend on the accuracy of guidewire placement, which requires biplane imaging [3]. To achieve this, the procedure is performed on a radiolucent operation table with traction being applied either manually or on traction assembly [4,5]. Even though these techniques are well established and commonly used, there are few associated difficulties in patient positioning, maneuvering, and intraoperative biplane imaging. The availability of a fracture table exclusive to the tibia is also an issue. It is not portable and requires significantly longer positioning time than manual traction, making it inconvenient and time-consuming [6]. Also, it does not allow sequential or simultaneous procedures in a polytrauma patient with multiple lower limb injuries without re-positioning or re-draping. Manual traction overcomes all these drawbacks of standard fracture table traction and significantly decreases the operative time [3]. Manual traction can be applied using a radiolucent foam triangle, adjustable knee and tibial positioner device, tibial and femur triangles, or hanging free leg technique [5]. However, the inventory required for the manual traction using the above-mentioned commercially available devices is cumbersome, and maintaining operative field sterility can also be an issue.
We have developed a simple autoclavable modular tibial stand to overcome these technical difficulties with manual traction application in the tibia nailing procedure.
Patients are operated on under suitable anesthesia (neuraxial block or general anesthesia as required) in the supine position, under tourniquet control. After sterile draping and prepping, ensured a free position of drapes such that the knee can be flexed up to 90 degrees. Next, the foot is draped separately. A modular tibial stand is assembled (Figure 1) and used throughout the procedure to keep the knee in various degrees of flexion based on the requirement (Figure 2).

Routine steps for tibia nailing are done. Various degrees of knee flexion possible with a modular tibial stand is described pictographically (Figure 3).

The important peculiarities of the tibial stand and its advantages have been described in Table 1. Even though it is metallic, it does not hinder intraoperative fluoroscopic views, as shown in Figure 5.

Closed tibia nailing is a popular and commonly performed operative procedure for treating tibial fractures [1]. For better postoperative outcomes, optimum fracture alignment, ease of intraoperative biplane imaging, and rotational control play an important role [2]. Intraoperative fracture alignment is obtained by applying traction in the long axis of the leg during guidewire and interlock nail negotiation [3]. There are various intraoperative positioning and traction application techniques during the tibia nailing [4,5]. These techniques have been summarized with the pro and cons of each technique (Table 2).
It has been shown that manual traction can significantly reduce the operating time compared to fracture table traction without compromising fracture alignment and outcome [3]. However, the commercially available inventory required for applying intraoperative traction can be cumbersome and on-table space-occupying [6].
We have found that modular tibial stand overcomes the difficulties associated with manual traction with excellent on-table biplane imaging and good axial and rotational control of the fracture possible by the assistant applying longitudinal traction. The assistant applying manual traction can easily control the intraoperative fracture site's rotational and axial alignment. The heavy tibial base plate provides improved stability, traction/countertraction ability, and good varus/valgus control. The height of the stand can be easily altered as per requirement because of the modularity of the various size cylindrical blocks of various lengths. Being made of stainless steel, it can be autoclaved easily.
Over the last 10 years, we have operated on over 600 cases of all tibial interlocking nailing using a modular tibial stand at our center. With the use of a tibial stand, we have found that the ergonomic of tibia nailing procedure has significantly improved in terms of reduced operative time, ease of intraoperative fluoroscopy, and traction application.
Obtaining satisfactory fluoroscopic images during the tibia nailing procedure and effective fracture site manipulation throughout the treatment necessitates proper intraoperative limb positioning. The use of a modular tibial stand, in our experience, takes care of both these concerns and assures that the results are repeatable. This could be a useful and safe alternative to the currently available limb positioning modalities during tibia-closed intramedullary nailing.
