Introduction: The TFN-ADVANCED Proximal Femoral Nailing System (TFNA) 235 mm (DePuySynthes) and Proximal Femoral Nail Antirotation (PFNA)-II 240 mm (DePuySynthes) were developed to obtain better stability for patients with trochanteric hip fractures without increasing surgical time and amount of blood loss. However, there are currently no studies concerning clinical and radiological outcomes of patients treated using these proximal femoral nails (PFNs) that have been performed in the Japanese population. The aim of this study was to retrospectively evaluate the clinical outcomes associated with 235 to 240 mm PFNs for Japanese patients >70 years old with trochanteric hip fractures who could walk independently before the injury. Materials and Methods: This study involved a retrospective analysis of data on trochanteric hip fracture patients who had undergone internal fixation from March 2016 to June 2018. The inclusion criteria were patients >70 years old with trochanteric hip fractures who could walk independently before the injury and were followed up for ≥3 months after surgery. Initially, 124 patients were identified, but 33 of these were excluded because other implants were used for internal fixation. Of the remaining 91 patients in whom PFNs were used at the time of internal fixation who were included for the perioperative evaluation, 66 patients followed up for ≥3 months were included in the clinical evaluations. Results: The average surgical time was 56.8 ± 19.6 minutes (range, 23-123 minutes). The average blood loss was 89 ± 41 mL (range, 0-245 mL). The union rate was 98%. Discussion: There were no cases of nail jamming, and all nails were successfully inserted below the end of the distal isthmus without additional reaming to dilate the canal. Conclusions: Proximal femoral nails were a useful implant in Japanese elderly patients with trochanteric hip fractures and gave comparable clinical outcomes despite the femoral length being short and occurrence of intensive bowing.

<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).

<p class="abstract"><strong>Background:</strong> Intertrochanteric fractures are one of the commonest fractures encountered in elderly population. Though there are various implants, proximal femoral nail has been the standard choice for management of unstable fractures. Inspite of its biomechanical advantages, various complications like screw cut out, Z effect, reverse Z effect does occur in proximal femoral nailing. The aim of the study is to analyse various factors determining the mechanical failures in patients operated with proximal femoral nail.</p><p class="abstract"><strong>Methods:</strong> This is a prospective study conducted in our institution from June 2014 to May 2018. The study included 72 patients with unstable intertrochanteric fractures treated with proximal femoral nail. All patients were followed for average period of 2 years. Functional outcome was assessed using Harris Hip score.<strong></strong></p><p class="abstract"><strong>Results:</strong> Among the patients<strong> </strong>33%<strong> </strong>had excellent outcome. 42% had good and 14% had fair outcome. 11% of cases ended with poor outcome. Mechanical failure rate was less in patients with positive medial cortical support (PMCS) and in patients with tip apex distance difference between antirotation screw and lag screw (TAD<sub>AR </sub>-TAD<sub>LS</sub>) more than 15 mm. Whereas the difference in the position of lag screw centre had no significant influence in the mechanical failure rate in our study.</p><p class="abstract"><strong>Conclusions:</strong> From our study we like to conclude that the<strong> </strong>fracture reduction with positive medial cortical support and the TAD difference play a major role in determining the incidence of mechanical failure in proximal femoral nailing.</p>

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.

Aims Restoration of proximal medial femoral support is the keystone in the treatment of intertrochanteric fractures. None of the available implants are effective in constructing the medial femoral support. Medial sustainable nail (MSN-II) is a novel cephalomedullary nail designed for this. In this study, biomechanical difference between MSN-II and proximal femoral nail anti-rotation (PFNA-II) was compared to determine whether or not MSN-II can effectively reconstruct the medial femoral support. Methods A total of 36 synthetic femur models with simulated intertrochanteric fractures without medial support (AO/OTA 31-A2.3) were assigned to two groups with 18 specimens each for stabilization with MSN-II or PFNA-II. Each group was further divided into three subgroups of six specimens according to different experimental conditions respectively as follows: axial loading test; static torsional test; and cyclic loading test. Results The mean axial stiffness, vertical displacement, and maximum failure load of MSN-II were 258.47 N/mm (SD 42.27), 2.99 mm (SD 0.56), and 4,886 N (SD 525.31), respectively, while those of PFNA-II were 170.28 N/mm (SD 64.63), 4.86 mm (SD 1.66), and 3,870.87 N (SD 552.21), respectively. The mean torsional stiffness and failure torque of MSN-II were 1.72 N m/° (SD 0.61) and 16.54 N m (SD 7.06), respectively, while those of PFNA-II were 0.61 N m/° (SD 0.39) and 6.6 N m (SD 6.65), respectively. The displacement of MSN-II in each cycle point was less than that of PFNA-II in cyclic loading test. Significantly higher stiffness and less displacement were detected in the MSN-II group (p < 0.05). Conclusion The biomechanical performance of MSN-II was better than that of PFNA-II, suggesting that MSN-II may provide more effective mechanical support in the treatment of unstable intertrochanteric fractures.
