Observations on AVN Development in Patients of Fracture Neck of Femur Treated with Delayed Fixation

ABSTRACT

Introduction: Incidence of displaced fracture neck of femuris high and there is lack of consensus over the definitivetreatment of such fractures as the incidence of complicationsespecially avascular necrosis remains very high. Objective ofthe study was to evaluate the incidence of avasular necrosisand its pattern in displaced fracture neck of femur managedwith osteosynthesisMaterial and methods: This study was a prospective studyconducted in Bone & Joint Hospital, Srinagar from 2003 to2018 on patients with displaced fracture neck of femur. Closereduction was done on traction table using Whitman’s Methodand reduction was confirmed under C Arm and was labelledsatisfactory using Lowell’s S Method and fixation was doneusing 3 Cannulated Screws of 6.5mm.Results: 118 patients {70 males and 48 females} with meanage 42.5 years {range 18 to 55 years} presented late in ourhospital which resulted in a delay in fixation from 24 hrs to7 days post trauma. Patients were followed till 2018 for aminimum period of 10 years.Conclusion: Our study suggest same AVN rates as of otherstudies if fixation is done within a period of one week.
