Assessment of fracture union in patients of subtrochanteric femoral fractures managed with dynamic condylar screw system and its association with type of fracture

ABSTRACT

Objective: To assessthe fracture union in patients of subtrochanteric femoral fractures managed with dynamic condylar screw system and its association with type of fracture. Material and methods: This was case series study and was conducted at Department of Orthpaedic Surgery DHQ Hospital Vehari. Total 80 patients with closed subtrochanteric fractures (within the 1 week of fracture) either male or female having age from 20 years to 70 years were recruited. Patients were managed with dynamic condylar screw system. Union of fracture was assessed after 8 weeks of surgery. Results: Mean age of the patients with subtrochanteric femoral fractures was 38.75±14.33 years and mean duration of fracture was 4.33±1.42 days. Total 80 patients were managed with dynamic condylar screw system and after 8 weeks, all the patients were assessed for union of fracture and union was found in 55 (69%) patients. Union of fracture was noted in 4 (26.27%) patients, 33 (89.19%) patients and 18 (64.29%) patients respectively in type A, B and C fracture. Highly significant association between union and type of fracture was noted with p value 0.000. Conclusion: Findings of present study showed high rate of union in patients of subtrochanteric femoral fractures treated by fixation with dynamic condylar screw system. Union of fracture is significantly associated with type of fracture and duration of fracture.
