Definition of sustentacular screw length based on computed tomography measurements for calcaneus intraarticular fracture surgery

Öz

Objective: It was aimed to define radiologically the length of the sustentacular screw for guidance of calcaneus intraarticular fracture surgery. Materials and Methods: In this radiological measurement study, computed tomography (CT) images of 200 (100 males, 100 females) patients who underwent multidetector lower extremity CT were investigated. CT axial sections were subjected to coronal and sagittal multiplanar reconstruction. The longest calcaneal diameters in the axial, sagittal, and coronal planes were measured. The distance between the standardized entry point of the screw on the lateral wall of calcaneus and the sustentaculum tali was measured. Results: Mean age was 42.31 ± 13.64 years (minimum, 18 years; maximum, 82 years). The distance from the determined point on the lateral wall to the sustentaculum tali (LSA) was measured along the axial plane and was 46.08 ± 4.34 mm in males and 41.37 ± 2.97 mm in females. The distance between the lateral wall and the sustentaculum tali (LSC) in the coronal plane was 50.15 ± 3.89 mm in males and 43.65 ± 3.50 mm in females. Conclusion: If mean community values are available, evaluation of screw length and calcaneal morphometry using preoperative images will enhance surgical success.

Kalkaneus intraartiküler kırık cerrahi tedavisinde bilgisayarlı tomografi üzerinden sustentakuler vida uzunluğunun belirlenmesi

Öz

Amaç: Çalışmada kalkaneus intraartiküler kırıkları cerrahisinde kullanılan sustentakuler vidanın boyunun radyolojik olarak belirlenmesi amaçlanmıştır. Gereç ve Yöntem: Bu radyolojik ölçüm çalışmasına, alt ekstremite bilgisayarlı tomografisi (BT) çekilmiş olan 200 hasta (100 erkek, 100 kadın) dâhil edildi. Aksiyel BT kesitleri görüntüleri, koronal ve saggital multiplanar rekonstrükte edildi. Kalkanusun aksiyel, koronal ve saggital plandaki en uzun mesafesi ölçüldü. Ayrıca sustentakulum talinin en çıkıntılı noktası ile standardize edilmiş kalkaneus lateral duvarındaki nokta arasındaki mesafe koronal ve aksiyel planda ölçüldü. Bulgular: Ölçüm yapılan BT’lerin ait olduğu kişilerin ortalama yaşı 42,31±13,64 (minimum, 18; maksimum, 82) idi. Aksiyel planda kalkaneustaki vidanın giriş yerine ait olan lateral duvar noktası ile sustentakulum tali arasındaki mesafe (LSA) erkeklerde 46,08±4,34 mm ve kadınlarda 41,37±2,97 mm idi. Koronal planda kalkaneustaki vidanın giriş yerine ait olan lateral duvar noktası ile sustentakulum tali arasındaki mesafe (LSC) erkeklerde 50,15±3,89 mm ve kadınlarda 43,65±3,50 mm idi. Sonuç: Topluma ait ortalama ölçümlerin bilinmesi durumunda, ameliyat öncesi yapılacak ölçümlerle birlikte hesaplanacak sustentakuler vida uzunluğu ve morfometrik ölçümler cerrahinin başarısını arttıracaktır.
