Effect of distal locking type on radiological results of proximal femoral nails used in the surgical treatment of hip fractures

Abstract

Purpose: The aim of our study is to obtain data that will shed light on the effect of the distal locking type of proximal femoral nails (PFN) on fracture healing, causes of general complications, especially those in the distal of the nails, and reduction of possible complication rates. Materials and Methods: Patients who underwent surgery with the diagnosis of trochanteric hip fracture between 01.01.2015 and 01.01.2020 and completed the second year follow-up time were examined from the medical records. Patients were grouped first according to AO/OTA sub-types (Three groups as AO A1, A2 and A3), then grouped according to distal locking type (Two groups as group 1: dynamic, group 2: static distal locking with 2 screws). The fracture type, healing status, fracture healing time, complication rates and reoperation because of complication development data were evaluated. Results: 339 patients enrolled in the study [189 women, 150 men, mean age: 76.24 (60-102) years]. The overall complication rate was 15.6%. AO A3 type fractures had long fracture healing times in each distal locking group compared to the other fracture sub-types. AO A3 type fractures had more frequent complication rates than the other subtype groups. AO A3 type fractures in group 2 had higher overall complication rates than in group 1. There was a significant correlation between group 1 and lag screw cut-out complication occurrence in females and between group 2 and pseudoarthrosis occurrence in males. In addition, there was a statistically significant relationship between the AO fracture sub-type and total rate of complication occurrence, AO A2 fracture type and lag screw cut-out complication occurrence and AO A3 fracture type and pseudoarthrosis complication occurrence. Conclusion: Patients with AO/OTA 31 A3 type fractures with static distal locking have a longer fracture healing time and a higher complication rate compared to dynamic locking. However, dynamic or static distal locking is not associated with other implant-related complications, especially those in the distal to the tip of PFN’s.

Öz

Amaç: Çalışmamızın amacı proksimal femoral çivilerin (PFN) distal kilitlenme tipinin kırık iyileşmesine etkisi, çivi distalinde olanlar başta olmak üzere genel komplikasyonların nedenleri ve olası komplikasyon oranlarının azaltılmasına ışık tutacak veriler elde etmektir. Gereç ve Yöntem: 01.01.2015-01.01.2020 tarihleri arasında trokanterik kalça kırığı tanısı ile ameliyat edilen ve ikinci yıl takip süresini dolduran hastalar tıbbi kayıtlarından incelendi. Hastalar önce AO/OTA alt tiplerine göre (AO A1, A2 ve A3 olmak üzere üç grup) daha sonra distal kilitleme tipine göre gruplandırıldı (Grup 1: dinamik, grup 2: 2 vida ile statik distal kilitleme yapılan hastalar olarak iki grup). Kırık tipi, iyileşme durumu, kırık kaynama süresi, komplikasyon oranları ve komplikasyon gelişimi nedeniyle tekrar ameliyat verileri değerlendirildi. Bulgular: 339 hasta çalışmaya dahil edildi [189 kadın, 150 erkek, ortalama yaş: 76.24 (60-102) yıl]. Genel komplikasyon oranı %15.6 idi. AO A3 tipi kırıkların her bir distal kilitleme grubunda diğer kırık alt tiplerine kıyasla daha uzun kırık kaynama süreleri vardı. AO A3 tipi kırıklar diğer tip gruplara göre daha sık komplikasyon oranlarına sahipti. Grup 2'deki AO A3 tip kırıkların genel komplikasyon oranları grup 1'e göre daha yüksekti. Grup 1 ile kadınlarda lag vidası sıyrılma komplikasyonu arasında ve grup 2 ile erkeklerde psödoartroz komplikasyonu gelişimi arasında anlamlı bir korelasyon vardı. Ayrıca, AO kırık alt tipi ile toplam komplikasyon görülme oranı, AO A2 kırık tipi ve lag vidası sıyrılması komplikasyonu gelişimi ve AO A3 kırık tipi ve psödoartroz komplikasyon oluşumu arasında istatistiksel olarak anlamlı bir ilişki vardı. Sonuç: Statik distal kilitleme yapılmış AO/OTA 31 A3 tip kırıklı hastaların, dinamik kilitlemeye göre daha uzun kırık kaynama süresine ve daha yüksek komplikasyon oranına sahip olduğunu göstermektedir. Bununla birlikte, bulgularımız dinamik veya statik distal kilitlemenin özellikle PFN'lerin distalinde olanlar da dahil olmak üzere implant nedenli diğer komplikasyonlarla ilişkili olmadığını göstermektedir.
