Abstract Introduction Proximal Femoral Nail Anti-rotation (PFNA) is a routine method to deal with intertrochanteric fractures in the elder population. It is extremely difficult to remove PFNA in some cases as a result of stripping of blade heads. In this Technical Note, we report a simple technique using commonly available instrument that can be used to remove stripped even broken anti-rotation blade where regular methods have failed. Methods The subject underwent a PFNA removal surgery fifteen months after the previous fixation. We encountered difficulties using regular instrument to remove the anti-rotation blade. A 5mm tungsten carbide bur was used to drill a single cortical hole at the end of the blade. Then double-strand steel wire was threaded through the hole and the distal part was shaped into a circle which could tie to the extraction screw. Slide Hammer was applied to gently knocked out the blade along the anatomical direction of the femoral neck. Results The technique helped us successfully remove the dispatched anti-rotation blade and provided the patient with a satisfactory result. Conclusion The use of a tungsten reamer and steel wire loop to remove the proximal femoral anti-rotation blade may provide a simple and cost-effective method of dealing with extraction failure.

Resumo Objetivo Identificar a energia necessária para ocorrência de fratura do fêmur proximal em osso sintético após retirada de três modelos de implantes: parafusos canulados, parafuso dinâmico do quadril (dynamic hip screw-DHS) e haste femoral proximal (proximal femoral nail-PFN). Métodos Foram utilizados 25 modelos de ossos sintéticos da extremidade proximal do fêmur: 10 unidades de grupo controle (GC), 5 unidades após colocação e retirada de 3 parafusos canulados colocados em configuração de triângulo invertido (GPC), 5 unidades após colocação e retirada do parafuso de compressão dinâmico (GDHS), e 5 unidades após colocação e retirada da haste de fêmur proximal (GPFN). Uma análise biomecânica foi realizada em todas as amostras simulando uma queda sobre o grande trocânter utilizando uma máquina servo-hidráulica com o objetivo de verificar a energia (em Joules [J]) necessária até a ocorrência de fratura nos diferentes grupos. Resultados Todos os grupos apresentaram fratura basocervical. Os grupos GC, GPC, GDHS e GPFN apresentaram, respectivamente, valores de 7.1J, 6.6J, 6J e 6.7J de energia até ocorrência da fratura. Não houve diferença estatisticamente significativa (intervalo de confiança de 95%) na energia entre os grupos de estudo (p = 0,34). Conclusão Não houve diferença estatisticamente significativa nos valores de energia necessária para ocorrência de fratura da extremidade proximal do fêmur após a retirada de três tipos de implantes utilizando modelos sintéticos simulando queda sobre o grande trocânter.

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.
