Abstract

Transpedicular screw fixation is a complicated surgical procedure that has reached substantial popularity in the treatment of spinal instabilities. This procedure is particularly valuable for simultaneous posterior decompression and reconstruction in the cervical spine. This anatomic study was undertaken to provide a set of anatomical data to aid the technique on a large series of human bony C7 cervical vertebrae from 49 individuals. The mean pedicle length was measured as 5.84±0.95 mm, pedicle width as 6.07±1.1 mm, and pedicle height as 6.82±1.01 mm. The distance from the posterior point of the lateral mass to the anterior margin of the vertebral body through the pedicle axis (pedicle axis length) was 30.37±2.41 mm, and the interpedicular distance was 21.62±1.33 mm mm. The lateral mass thickness was measured as 21.99±1.35 mm. Successful placement of the pedicle screw requires a thorough knowledge of cervical spine transpedicle morphometry. The approximate values from the morphometric studies such as our study can be a guide in choosing the appropriate screw dimensions and to avoid the damage to important neighbouring neurovascular structures

Özet

Transpediküler vida fiksasyonu omurga instabilitelerinde son zamanlarda sıklıkla kullanılan bir cerrahi müdahaledir. Bu yöntemle omurgada posterior dekompresyon ve rekonstrüksiyon aynı anda yapılabilir. Bu anatomik çalışmada, transpediküler vida fiksasyonunda tekniğe yol gösterici olması amacıyla 49 adet insan C7 omurunun pediküllerinin anatomik özelliklerinin belirlenmesi hedeflendi. C7 omurun ortalama uzunluğu 5.84±0.95 mm, yüksekliği 6.82±1.01 mm, pedikül genişiliği 6.07±1.1 mm olarak bulundu. Massa lateralis’in arka kenarından corpus vertebra’nın ön kenarına olan mesafe (pedikül eksen uzunluğu) 30.37±2.41 mm, interpediküler mesafe 21.62±1.33 mm ölçüldü. Massa lateralis kalınlığı 7.64±1.4 mm idi. Başarılı bir vidalama pedikül anatomisinin ayrıntılı olarak bilinmesi ile mümkün olur. Bu çalışma gibi morfometrik anatomik çalışmalardan elde edilen bulgular daha iyi bir cerrahi yaklaşıma ve pedikül komşuluğundaki önemli nörovasküler yapıların korunmasını amaçlar.
