AbstractBackground: Femoral neck fracture is a very common injury encountered in orthopedics.The old fracture neck femur fixation is a great challenge to orthopaedic surgeons. The obliquity of the fracture line leads to shearing forces at the fracture site. By doing valgus osteotomy shearing forces are converted into compressive forces and it also compensates for the limb length shortening that occur due to absorption of neck and compressive forces increases healing. In this study, we have assessed the functional outcome of valgus osteotomy and fixation by dynamic hip screw (DHS) in femoral neck fracture patients.
Material and Methods: 10 cases which were diagnosed with fracture non union neck femur were included in this study. The details of history, mode of injury, time since injury, other relevant history for chronic illness, clinical and radiological examination, Harris Hip Score (HHS) were noted at the time of admission. All patients underwent valgus osteotomy and fixed using 135° angled dynamic hip screw and barrel plate assembly. Post operatively x-rays were done at 1 month, 3 months, 6 months and 1 year. At each visit Harris hip score was taken.
Results: In our study the time taken for fracture union was 5.00 ± 0.82 months with union seen in all the patients at the end of 12 months. HHS in 3 patients was excellent, good in 6 patients and fair in 1 patient. Mean HHS at end of 12 months was 84.30 ± 5.79.
