Abstract

Objective: To evaluate the results of segmental bone transport using monoaxial external fixator in patients
with non union of the tibia with segmental bone loss.
Material and Methods: This descriptive study was carried out at orthopedic unit of Hayatabad Medical
complex Peshawar from July 2004 to January 2007 with 32 patients of tibial non union with segmental
bone loss. Locally made "Naseer-Awais" uniplanner external fixator was applied and osteotomy
performed. Distraction started at tenth post operative day. Patients were followed fortnightly. Check
radiographs were taken on every visit. At the end of consolidation phase fixtor was removed. Results were
assessed using Association for the Study and Application of the Method of ILIZAROV (ASAMI) scoring
system.
Results: Out of 32 patients 29 were male and 3 were female. Eighteen patients had road traffic accidents,
10 fire arm injuries and 4 bomb blast injuries. Average length of bone transport was 7cm. Average
duration of fixator was 8 months and average follow up was 25 months. Eight(25%) patients had some
additional procedure in form of fibular osteotomy, fasciocutaneous flap and bone grafting. Twentyeight(
87.5%) patients had pin tract infection. Repositioning of pins was done in 18(56.25%) patients.
External fixator was changed in 10(31.25%) patients. Four patients developed mal-alignment which
required fixator resetting. Four(12.5%) patients had re-osteotomy. Five(15.62%) patients developed
persistent equinus deformity Nine(28.12%) patients had to modify their profession.
Conclusion: Distraction osteogenesis can be achieved with locally made Naseer Awais fixator in non union
of tibia with segmental bone loss.
