<p class="abstract"><strong>Background:</strong> The incidence of inter trochanteric fracture is expected to have doubled by 2040. Inter trochanteric fractures account for about 45% to 50% of all hip fractures in the elderly populationand out of these, near about 50% to 60% are classified as unstable intertrochanteric fractures. The goal of treatment is restoring mobility safely and efficiently, while minimizing the risk of medical complications and technical failure. This study as performed<strong> </strong>to assess functional outcome with dynamic hip screw and proximal femoral nail in intertrochanteric fracture management.</p><p class="abstract"><strong>Methods:</strong> It was prospective observational study done for a period of 1year from January 2016-January 2017 among patients who attended OPD or emergency department with intertrochanteric fracture. Two different implants were used dynamic hip screw (DHS) and proximal femoral nail (PFN).<strong></strong></p><p class="abstract"><strong>Results:</strong> Excellent results in functional outcome was more in case of PFN (66.6%) compared to DHS (50%). The type of trauma in DHS group was road traffic accident in 38.8%, domestic fall in 50% and others such as assault was in 11.1% while in PFN group intertrochanteric fracture was seen in 61.1% due to domestic fall.</p><p class="abstract"><strong>Conclusions:</strong> The functional outcome was more better with proximal femoral nail (PFN) compared to dynamic hip screw (DHS). Therefore, proximal femoral nail (PFN) should be preferred for management of intertrochanteric fractures.</p>

Background. The dynamic hip screw (DHS) with the addition of an angular stable trochanter-stabilizing plate (TSP) has been considered the ideal treatment for the unstable intertrochanteric fracture type. However, there have been few comparisons between DHS+TSP augmentation with intramedullary (IM) nailing. The aim of this retrospectively registered study was to compare the clinical outcomes of patients with the unstable type of intertrochanteric fractures treated with DHS+TSP or IM nailing (proximal femoral nail antirotation (PFNA)). Methods. From June 2013 to April 2018, 358 patients with proximal femur fracture AO/OTA type 31A2 and 31A3 treated with PFNA or DHS+TSP and followed for ≥10 months postoperatively were included. The surgical-dependent outcome evaluation included the operation time, intraoperative blood loss, postoperative decrease in hemoglobin, and blood transfusion amount. Functional status was also measured. Radiographic findings and postoperative complications were recorded and analyzed. Result. The operation time was significantly shorter in the DHS+TSP group than that in the PFNA group for both A2 and A3 fractures (A2 type: 84.0 vs.96.4 min; p<0.05; A3 type: 102.4 vs.116.1 min; p<0.05). Postoperative decrease in hemoglobin was more significant in the PFNA group than that in the DHS+TSP group for both fracture types (A2 type: −1.88 vs. −1.29 (mg/dL); p<0.05; A3 type: −1.63 vs. −1.04 (mg/dL); p<0.05). However, the patients treated with DHS+TSP had significantly more residual pain than those treated with PFNA during the final follow-up (Visual Analog Scale score, A2 type: 28.4 vs.23.2; p<0.05; A3 type: 27.5 vs.23.6; p<0.05) and complained of greater implant irritation. Conclusion. We found that DHS+TSP was associated with less operation time and less postoperative decrease in hemoglobin but more residual pain and implant irritation than those of PFNA. As a treatment for unstable intertrochanteric fracture, DHS+TSP provided ideal surgical outcomes which were not inferior to the PFNA.

Introduction: Application of dynamic hip screw (DHS) implant for the treatment of unstable intertrochanteric fractures continues to raise concern related to risk of lag screw cut-out with or without subsequent damage to the acetabulum. Measurement of tip-apex distances (TAD) has been recommended to guide the optimal placement of lag screw and to predict subsequent risk of screw cut-out. In this study, the value of TAD was evaluated to verify its usefulness. Methods: This is a retrospective study of 33 consecutive patients with intertrochanteric fracture treated with DHS. Demographic data of the patients were traced from their case notes. Post-operative radiographs were reviewed by focusing on measurement of TAD on anteroposterior and lateral radiographs. Radiographs at one year follow-up were reviewed to depict any fixation-related failure or complication. Results: Fifty two percent of patients did not achieved the recommended TAD of ≤ 25mm. The mean post-operative TAD was 25.9mm and elderly patients were likely to achieve TAD of ≤ 25mm. The overall complication rate of 6% was attributed to screw cut-out in two cases. The unstable left-sided fracture was identified to be a potential risk for screw cut-out or migration. Conclusion: TAD is a valuable measurement to guide optimal placement of lag screw during DHS fixation of intertrochanteric fracture.
