A novel technique for reduction and immobilization of tibial shaft fractures: the hammock

Standard techniques for immobilization of a tibia shaft fracture in the emergency department in a long-leg splint can be cumbersome, technically difficult, and often requires the use of an assistant. We have developed a novel technique for the reduction and splinting of tibial shaft fractures, which uses a "hammock" constructed of stockinette, which allows a single consulting orthopaedic physician to rapidly reduce and place a long-leg plaster splint or cast on a patient. This technique was performed on 12 consecutive patients with a total of 12 tibial shaft fractures. Translation, angulation, and shortening of the fracture were documented in anteroposterior and lateral views of the injured tibia and these parameters were compared against values measured after the hammock technique was used to reduce and splint the fracture. Pre-"hammock" average values for fracture displacement in the anteroposterior plane for translation, angulation, and shortening were 10.5 mm (53.1%), 12.0°, and 9.4 mm, respectively. Post-"hammock" average values for fracture displacement in the anteroposterior plane for the same parameters were 8.7 mm (44.4%), 4.2°, and 7.9 mm, respectively. Pre-"hammock" average values for fracture displacement in the lateral plane for translation and angulation were 4.9 mm and 8.7°. Post-"hammock" average values for fracture displacement in the lateral plane for the same parameters were 4.9 mm and 2.0°, respectively. These results show that this technique is able to achieve the goals of fracture reduction and immobilization in a rapid fashion when help is not available.
