A comparative study of Dynamic Hip Screw and Proximal Femoral Nail in the management of Intertrochanteric Fractures of the Femur

Introduction: Intertrochanteric fractures account for approximately half of the hip fractures in the elderly because of the osteoporotic nature of the bone. There are various modalities to treat these fractures. The objective of this study was to compare and evaluate the clinical and radiological outcome of intertrochanteric femur fracture treated with Dynamic hip screw (DHS) and proximal femoral nail (PFN). Methods: This study was conducted at Nepalgunj medical college, Department of orthopedics Nepalgunj over a time span of two years. A total of 52 patients were included and randomized into Dynamic hip screw (n=26) and Proximal femoral nail (n=26) group. Patient’s demographic details, perioperative findings, radiological findings and follow up findings were recorded. The results were evaluated and compared. Results: The mean age in our study was 57.63 years. Trivial fall was the most common mode of injury. There was significantly higher intraoperative blood loss in the DHS group. Radiological union and functional outcomes were similar overall, but in case of unstable fracture functional outcome was clinically better in PFN group. Conclusion: From our study we concluded that PFN has better outcome in case of unstable intertrochanteric fractures, however in stable fracture also it has distinct advantage over DHS.

Background: Unstable fractures accounts for approximately 50 to 60% of all intertrochanteric fractures. Failure rates of (DHS) dynamic hip screw for unstable fracture patterns are as high as 50%. Proximal femoral nail is technically more demanding surgery and also associated with complications like implant failure, femoral shaft fracture, improper reduction, screw cut-out and non-union. This study was done to compare the results of using Trochanteric stabilization plate in addition to dynamic hip screw versus proximal femoral nail which is considered as a better implant for unstable fractures.Methods: A prospective study was conducted comparing outcomes of proximal femoral nailing versus trochanteric stabilization plate with dynamic hip screw for 44 patients with unstable intertrochanteric fractures (22 each). Harris hip scoring system and Parker mobility score was used for evaluation.Results: In our study, Average time of union in all 22 patients of PFN group was about 12 weeks while average time of union in all 22 patients of DHS with TSP group was about 14 weeks. The Harris hip score was 85.45 in DHS with TSP group while it was 84.72 in the PFN group (p=0.846). The Parker mobility score was 7.81 in the DHS with TSP group while it was 7.95 in the PFN group (p=0.728). Conclusions: Use of TSP with DHS can give good results in unstable IT fractures. Addition of TSP to DHS gives good lateral wall buttress which prevent excessive medialisation of shaft and gives comparable result to PFN.

Background: 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 to assess functional outcome with dynamic hip screw and proximal femoral nail in intertrochanteric fracture management.Methods: 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).Results: 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.Conclusions: 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.

BACKGROUND Current management of Intertrochanteric (IT) fractures has evolved with the introduction of dynamic hip screw (DHS) and proximal femoral nail (PFN). The purpose of this study was to compare the functional outcomes between the DHS and PFN for IT fracture fixation. METHODS This study is a retrospective comparative analysis of 455 patients with IT fractures; DHS (292) and PFN (163), who were treated from June 2012 to June 2015. The patients were reviewed postoperatively for a minimum of 12 months to evaluate functional outcome using Salvati-Wilson score. Categorical data was present as absolute number or percentages, and parametric variables were presented as Mean ± SD, while non parametric data were presented as median. Statistical significance was defined as P < 0.05. RESULTS Intramedullary nails offer no advantage over extramedullary devices to treat IT fractures caused by low-energy trauma (AO 31 - A1). However, clinically significant outcomes were established for PFN group in terms of duration of surgery, x- ray exposure and SW Score for AO / OTA 31 - A2 and 31 - A3. Reoperations encountered for local pain due to implant prominence were significantly higher in the PFN group (4.90 % versus 1.02 %). Kaplan Meier survival probability of 69.3 % and 79.5 % predicted for DHS and PFN respectively, 3 years postoperatively. CONCLUSIONS Our conclusion reinforces indication for PFN in unstable IT fractures (31 - A2 and 31 - A3), owing to its better functional outcome and biomechanical properties. Functional outcomes for stable IT fracture (AO 31 - A1) were comparable between DHS and PFN, therefore final decision for implant choice depends on implant cost, surgeon’s preference for specific technique. However, understanding the morphology of proximal femur, peritrochanteric region is crucial to analyse the anatomical variations in Indian population which will provide the basis for intramedullary nail design modifications.

Objective: To analyze the effects of dynamic hip screw (DHS) and anatomical locking plate in the treatment of intertrochanteric fractures in elderly patients. Method: 56 cases of intertrochanteric femur fracture from March 2009 to October 2011 were treated by surgical treatment. The cases were divided into A and B groups with A group treated with DHS and B group with anatomical locking plates. Results: Treatments of the two groups were successful. Operation time, bleeding volume, postoperative drainage, hospitalization time and fracture healing time of B group were significantly less than that of A group (p < 0.05). The incidence of postoperative complications in B group was significantly less than that in the A group (p < 0.05). The excellent and good ratings of B group was 93.1% and 66.7% for the A group. The fine rating of B group was higher than that of A group (p < 0.05). Conclusion: Anatomical locking plate internal fixation for the treatment of intertrochanteric fractures in the elderly has certain advantages.
