For intramedullary nailing of femoral shaft fractures, talon fixation is helpful to cope with the troublesome distal locking, but conventional distal locking with screws offers a more stable construct: Talon femoral nail versus conventional femoral nail Femur şaft kırıklarının intramedüller çivilenmesinde, talon fiksasyonu zahmetli distal kilitlemeyle başa çıkmada yararlıdır, ancak vidalarla konvansiyonel distal kilitleme daha stabil bir yapı sunar: Talon femoral çiviye karşı konvansiyonel femoral çivi

All rights reserved.BACKGROUND: A novel-design femoral nail (FN) with distal talon deployment (Talon-FN) has emerged in the market to cope with problematic distal locking. We aimed to compare the radiological and functional outcomes of the Talon-FN with a conventional FN (Con-FN) for the treatment of femoral shaft fracture (FSFs). METHODS: This retrospective study included 85 patients (57 men, 28 women; mean age: 46.8±23.9 years) with FSFs (AO types 32-A and B) who were treated with FNs (Talon-FN: 41, Con-FN: 44) during October 2014–2018. Knee injury and Osteoarthritis Outcome Score Physical Function Shortform, Hip injury and Osteoarthritis Outcome Score Physical Function Shortform, Short musculoskeletal function assessment bother and dysfunction indexes were used for functional assessment. RESULTS: The mean follow-up time was 25.8±6.7 months. The complication rates were 19.6% and 20.5% for Talon-FN and Con-FN, respectively (p=0.92). Malunion was the most common complication for each FN type (Talon-FN: 9.8%, Con-FN: 9.1%). All of the Talon-FN group’s malunions were axial (shortening and malrotation) and happened gradually. In contrast, the Con-FN group’s malu-nions were angular (varus and valgus) and caused by initial malreduction. The Talon-FN group’s two patients with shortening (4.9%) had AO 32-B type fractures, and the other two with malrotation (4.9%) had AO 32-A3 type fractures, all of four fractures were localized distal to the femoral isthmus. The post-operative functional outcomes were similar between the groups (all p>0.05). The mean op-eration/fluoroscopy time and the mean blood loss were lower in the Talon-FN group, while the mean union time was shorter in the Con-FN group (all p<0.01). No nonunion was noted in either group. The reoperation rates were similar at approximately 5% (p=0.95). CONCLUSION: Our study results revealed that the Talon-FN shortens the operation/fluoroscopy time and decreases the intra-operative blood loss with similar functional outcomes. However, the Con-FN seems to offer a more stable construct against axial malunion with a shorter bone union time. The Talon-FN should not be used in FSFs distal to the femoral isthmus with certain types of fractures prone to shortening and malrotation.
