Bone Mass Density Assessment by Dual-Energy X-Ray Absorptiometry (Dexa) in Intertrochanteric Fracture of Femur Treated by Fixation

Abstract

Objective: To assess the differences in bone mass density (BMD) by Dual-Energy X-R.ay A bsorptiometery (DE XA ) in intertrochanteric fractures before and after fixation. Methods: This quasi experimental study was conducted in the department of Orthopedics and Traumatology, LtJ M HS. Jamshoro from June 2016 to Dec 2017, on 40 close Intertrochanteric femur fracture patients above 45 r-ars. The fracture was diagnosed by plain X-ray, after confirmation, the fiNt preoperative Bone Mass liensity (BMD) was measured by Dual-energy X-ray Absorptiometry and result was kept on record. Then On weeks after fixation BMD was measured and after every 06 weeks of fixation BMD was measured up to 26 weeks. The data collected was statistically analyzed. Results: The average age of the patients was 60.03 ± 11.21years. There were 22 (55'.0 males. mean BMD was significantly reduced at 2"d, 8th, 14', 20th and at 26th weeks after fixation as compared to before fixation (p<0.001). Pain was observed in all cases before fixation but reduced overtime after fixation. Wound condition was also observed and it was found that 3 to 5 wounds of patients were infected durint2 2 to 14 weeks while during 20 to 26 weeks, I case was round infected and 97.5% wounds were healed at 26 weeks after fixation. Pain and slight pain on weight bearing was reported in 100% cases during 2 to 8 weeks after fixation and reduced overtime with 95% cases reported no pain on full weight bearing and 5"./0 reported slight pain 26 weeks after fixation. Conclusion: DEX A is a quick, accurate, low-cost imaging method for the evaluation of bone mineral density.
