Abstract
Neck of femur fractures have often been termed as "The Unsolved Fractures", since they have a guarded outcome even after improved understanding of biomechanics and biology of this area. Gap-nonunion is one such dreaded complication of this fracture, especially in younger (<60 years) population, where arthroplasty may not be the best go-to option. We have earlier described "The AIIMS BOX" technique to manage such cases of gap non-union in neglected neck femur fractures [1]. Here we intend to describe a more successful modification of this technique. We operated 7 cases of gap non-union with our new "Cage in Box" strategy and followed these cases for 5 years. 6 patients from this group achieved excellent to good outcomes and only 1 reported a poor outcome. All the patients, except the one with poor outcome, could walk without aid and do activities of daily living independently. 3 patients developed AVN but had no evidence of collapse. 3 patients also developed Coxa vara, but it was significant only in one case. 6/7 patients were able to squat. We describe this method in detail and feel this can be a viable option in the armamentarium of orthopedic surgeons, along with valgus osteotomy, vascularized and non-vascularized fibular strut graft as well as Meyer's Graft, to help them solve this unsolved fracture.
