Abstract

In this study, 31 adolescent idiopathic scoliosis patients were evaluated etrospectively. Posterior instrumentation and usion were applied to the patients as surgical ntervention. The patients were divided into two groups according to the application of either hooks or pedicle screws at the superior vertebrae of instrumentation. The capital angle between inferior end plate of the superior vertebrae of the instrumented spine and the superior end plate of the vertebrae two levels above was measured. The two groups were compared in the preoperative, early postoperative and late postoperative periods by using lateral roentgenograms in terms of the angle of proximal junctional kyphosis. The results of this study demonstrated that the angle degree of the proximal junctional kyphosis increased significantly more in the pedicle screw group early in the postoperative period than the hook group and resulted in abnormal proximal junctional kyphosis. The fixation was established adequately rigid and proximal junctional kyphosis was measured higher in pedicle screw group than hook group. Only one patient had abnormal angle in our study and we attributed this low number of patients to the short follow-up time of these patients.

Özet

Geriye dönük olarak yapılan bu çalışmada, adölesan idiopatik skolyoz hastası olan ve cerrahi tedavi uygulanan 31 hasta incelendi. Cerrahi tedavide posterior enstrümantasyon ve füzyon uygulanan hastalar enstrümantasyonun üst bölgesinde çengel veya pedikül vidası uygulanmasına göre iki gruba ayrıldı. Bu iki grubun preoperatif, erken postoperatif ve geç dönem poliklinik kontrollerinde çekilmiş yan radyografilerinden ölçülen üst kavşak bölgedeki kifoz açıları karşılaştırıldı. Posterior enstrümantasyon esnasında üst vertebraya pedikül vidası uygulandığında çengel uygulanmasına göre sistem daha rijit olmakta ve proksimal kavşak bölgesinde üst kavşak kifoz açısı değerlerinin zamanla artmasını engellediği düşünülmektedir. Bu çalışmada pedikül vidası uygulanan hastalarda erken postoperatif üst kavşak kifoz açı değerlerinin zamanla artış gösterdiği, eğilmenin çengel uygulanan grupta daha fazla olduğu ve üst bölgede anormal kavşak kifozuna yol açabileceği bulundu. Bizim çalışmamızda sadece bir hastada anormal üst kavşak kifozu görüldü. Ayrıca proksimal bölgede pedikül vidası kullanıldığında çengel grubuna göre daha kısa segment füzyona ihtiyaç duyulduğu bulundu.
