BackgroundThis study aimed to compare the clinical and radiological outcomes of conventional locked intramedullary nailing (IMN) and talon IMN in AO Type 42A tibial fractures.MethodsA total of 93 patients with AO Type 42A fracture were retrospectively analyzed. The patients were divided into two groups: Those treated with conventional IMN (Group 1), and those treated with talon distal locked nailing (Group 2). The patients were statistically compared in terms of age, sex, mechanism of injury, follow-up time, time to union, smoking status, presence of open fracture, presence of concomitant fibula fracture, development of malunion and nonunion, and the number of intraoperative fluoros-copy shots captured. All patients were evaluated with American Orthopaedic Foot and Ankle Society and Tegner Lysholm scores for clinical outcomes.ResultsA total of 93 patients (68 men and 35 women) participated in the study. Group 1 consisted of 35 (71.4%) men and 14 (28.6%) women, a total of 49 patients, while Group 2 consisted of 33 (75%) men and 11 (25%) women, a total of 44 patients. There were no significant differences between the two groups in terms of age, sex, mechanism of injury, follow-up times, smoking status, concomitant fibula fracture, presence of malunion, and presence of open fracture (p>0.05). However, there were significant differences between both groups in terms of time to union, nonunion rate, and the number of fluoroscopy shots captured (p<0.05). American Orthopaedic Foot and Ankle Society and Tegner Lysholm score were analyzed and compared, no statistically differences were found (p=0.786 and p=0.764).ConclusionAlthough talon IMN reduces radiation exposure, locked conventional IMN has lower nonunion rates and achieves union faster.
