Safety of Skeletal Traction through the Distal Femur, Proximal Tibia, and Calcaneus

Introduction: Skeletal traction provides pain relief and temporary stability in patients anticipating surgery for a variety of lower‑extremity fractures. Recent literature suggests that distal femoral traction provides pain relief and is safe; however, data regarding proximal tibial and calcaneal pins are primarily historical and limited. The purpose of this study is to document complications associated with distal femur, proximal tibia, and calcaneal traction pin placement. Materials and Methods: We identified patients with the distal femur, proximal tibia, and calcaneal traction pin placement from January 2013 to June 2016. Chart review was utilized to identify any complications, including nerve or vascular injuries, need for revision, or infection. Results: Five hundred and nineteen traction pins were eligible for review, consisting of 120 calcaneal traction pins, 129 distal femoral pins, and 270 proximal tibia traction pins. Primary diagnosis was defined as 305 femur fractures (58.8%), 60 tibial shaft fractures (11.6%), 60 acetabular fractures (11.6%), 38 pilon fractures (7.3%), 30 pelvic ring injuries (5.8%), 21 tibial plateau fractures (4.0%), and 5 hip dislocations (1.0%). We identified 17 (3.3%) adverse events potentially attributable to traction pin insertion. Pins that became infected were found to have been in place for a significantly longer duration (18.3 days compared to 5.8 days, P = 0.0001). Conclusions: Traction pin placement for skeletal traction is generally an uncomplicated procedure. Duration of pin placement is significantly related to the likelihood of pin site infection.
