Objective: To find the results of interlocking static nail in management of segmental tibia fractures and to achieve union, by maintaining length, alignment and rotational stability of fracture segments.
Methodology: In this prospective cross sectional study, we analyzed clinical data of 23 patients with segmental tibia fracture at the department of Orthopedics Surgery, Dow University of Health Sciences/Dr. Ruth K.M. Pfau Civil Hospital, Karachi, Pakistan from January 2017 to December 2019. All patients were treated with interlocking static nail.
Results: Out of 23 patients, 18 were male (78%), five female (22%). Thirteen patients (57%) out of 23 had right side while 10(43%) had left side segmental tibia fracture. Mode of injury in all patients was road traffic accidents. Out of 23 patients, three (13%) had grade I open fractures which were treated with wound debridement after which fixation with interlocking static nail was done later on. Closed interlocking nailing was done in all patients except four (17%) in whom fracture site was reduced open. Union was achieved in distal tibia in 4-5 months; one patient (5%) developed nonunion and two with distal tibia developed talar tilt. Post-operative complications were superficial infection at entry site in four patients (17%), two (9%) had superficial infection at distal screw insertion site while only one (5%) developed deep infection. Four patients (17%) complained of anterior knee pain.
Conclusion: Closed reduction and internal fixation with interlocking nail was successful in treatment of segmental tibia fractures with respect to achieving union, early range of motion and quick return to pre injury work status.
Key words: Interlocking nail, segmental tibia, tibial fracture.
