Recommendations for avoiding knee pain after intramedullary nailing of tibial shaft fractures

Abstract

Background: The objective of this study is to analyze the proximal tibiofibular joint in patients with knee pain after treatment of tibial shaft fractures with locked intramedullary nail.Findings: The proximal tibiofibular joint was analyzed in 30 patients, who reported knee pain after tibial nailing, and standard radiograph and computed tomography were performed to examine the proximal third of the tibia. Twenty patients (68.9%) presented the proximal screw crossing the proximal tibiofibular joint and 13 (44.8%) had already removed the nail and/or screw. Four patients (13.7%) reported complaint of knee pain. However, the screw did not reach the proximal tibiofibular joint. Five patients (17.2%) complained of knee pain although the screw toward the joint did not affect the proximal tibiofibular joint.Conclusion: When using nails with oblique proximal lock, surgeons should be careful not to cause injury in the proximal tibiofibular joint, what may be one of the causes of knee pain. Thus, the authors suggest postoperative evaluation performing computed tomography when there is complaint of pain. © 2011 Labronici et al; licensee BioMed Central Ltd.
