Abstract
Nonunion after intramedullary nailing (IMN) in patients with tibial shaft fractures occurs up to 16%. There is no agreement whether reaming prior to IMN insertion would reduce the nonunion rate. We aimed to compare the nonunion rate between reamed and unreamed IMN in patients with tibial shaft fractures.A systematic search was conducted in Pubmed, Embase, and the Cochrane Library. The selected publications were: (1) randomised controlled trials; (2) comparing the nonunion rate; (3) in patients with tibial shaft fractures; (4) treated with either reamed or unreamed IMN.Seven studies that satisfied the criteria were identified. They showed that reamed IMN led to reduction of nonunion rate compared to unreamed IMN in closed tibial shaft fractures (risk difference ranging 7.0–20%, number needed to treat ranging 5–14), while the difference between compared treatments for open tibial shaft fractures was not clinically relevant.The evidence showed a consistent trend of reduced nonunion rate in closed tibial shaft fracture treated with reamed compared to unreamed IMN.
