Background: Cubitus varus is the most common delayed complication that results following supracondylar fracture of humerus in children with reported incidence 9%–58% in various series, with an average of 30%. Many types of corrective osteotomies with several fixation techniques proposed to correct this deformity.The dispute lies in the type of fixations which are most stable with minimum complications.Present study was designed to compare between fixation of modified French osteotomy for cubitus varus deformity with Tension bend wire and plate. Methods: A randomized comparative study (prospective) was conducted on 30 patients (5 to 15 years) with cubitus varus deformity (>10 degrees). In 15 cases the osteotomy was fixed with a figure-of-8 wire loop tightened over the screw heads (TBW Group) and in the other 15cases the osteotomy was fixed with plate (PLATE Group) in the Department of Orthopaedics and followed up for 24 weeks. Patients’ functional outcome were assessed with help of Bellmore’s criteria post-operatively. Results: Excellent outcome was observed postoperatively after 24 weeks with respect to difference of ROM-53.33 %, carrying angle - 66.66 %, LCPI- 46.66 % and post operative complications- 93.33 % in PLATE group as compared to TBW group in whom ROM-26.66 %, carrying angle 46.66 %, LCPI- 33.33 % & post operative complications- 73.33 %, respectively. Only 6.66 % cases had poor outcome with respect to ROM and carrying angle in PLATE group as compared to 26.66 % cases in TBW group. Conclusion: The osteotomy fixed with plate had better outcome and provides more stability and early mobilization as compared to TBW.
