ABDUCTION OSTEOTOMY IN COXA VARA DUE TO PAEDIATRIC FEMORAL NECK NON UNION. AN OUTCOME STUDY WITH DC PLATE
Journal Title: Journal of Indira Gandhi Institute of Medical Sciences - Year 2019, Vol 5, Issue 1
Abstract
Abstract: Coxa vara due to femoral neck non union is a common presentation. It is treated by abduction osteotomy usually fixed with DHS or double angle DCS. Narrow DCP was used to fix the osteotomy and fracture site together in 12 patients with average age of 6.1 yrs. Pre operative average neck shaft angle was 91.660 Pauwel’s angle was 61.250, shortening was 1.75 cm and neck was retroverted 10.410. Postoperative average neck shaft angle was 115.80, Pauwel’s angle was 38.50, persistent limb shortening was noticed in 3 cases and lengthening of 1.0 cm in one case. All the cases had complete union of osteotomy site in 7.5 weeks and fracture site in 12.5 weeks on average. No bone grafting or hip spica was done. Over 2 yrs follow up the implant position was intact, no loosening and change of neck shaft angle was noted. We conclude that narrow DCP is a good implant to fix these osteotomies and Pauwel angle correction is more important than correction of neck shaft angle.
