Abstract

Objective: The true incidence and clinical impact of instability at the adjacent segment after stabilization of the lumbar spine was unclear. This study investigates development of disc herniation or instability at the adjacent segment after stabilization of the lumbar spine. Methods: Twenty-nine patients who were operated upon using short segment posterior instrumentation and fusion were evaluated for development of adjacent upper segment disc herniation and instability. Stabilization and fusion were performed for listhesis or the presumed instability after stenosis operation or unstable disc herniation. In all patients, pre- and postoperative MRIs and X-ray images were obtained. In MRI, disc herniations were evaluated. In X-ray, slippage and rotational angling of the adjacent upper segment were measured. Results: Three patients had disc herniation and six patients had instability at the adjacent segment. No statistical correlation was found between development of instability and disc herniation and age, gender of the patient, type of the pathology, or the level stabilized. Conclusions: Stabilization and fusion were suff icient for the patients and did not produce too much instability at the adjacent upper segment. Randomized studies with more patients and diff erent instability criteria are needed to better understand adjacent segment instability

Özet

Amaç: Lomber omurga sabitlemesinden sonra gelişen komşu segment instabilitesinin gerçek insidansı ve kliniğe yansıması aydınlatılmamıştır. Bu çalışma lomber omurga sabitlemesinden sonra komşu segmentte disk hernisi veya instabilite gelişiminin incelemesi amaçlanmıştır. Yöntem: Kısa segment posterior enstrümantasyon ve füzyon uygulanan 29 hasta komşu segmentte disk hernisi veya instabilite gelişimi açısından incelenmiştir. Sabitleme ve füzyon listezis, instabil disk hernisi veya stenoz ameliyatı sonrasında gelişen instabilite nedeni ile uygulanmıştır. Tüm hastalara ameliyat öncesi ve sonrası MRG ve röntgen çekilmiştir. MRG’de komşu segment disk herniasyonu, röntgende kayma ve rotasyonal açılanma değerlendirilmiştir. Bulgular: Üç hastada komşu segmentte disk herniasyonu, 6 hastada instabilite saptandı. İnstabilite ve disk herniasyonu gelişimi ile hastaların yaşı, cinsiyeti, patolojinin tipi veya sabitlenen seviye arasında istatistiksel bağlantı bulunamadı. Sonuç: Sabitleme ve füzyon komşu segmentte anlamlı derecede instabiliteye neden olmamaktadır. Daha fazla hasta ile ve farklı instabilite ölçütleri ile yapılacak randomize çalışmalar komşu segment instabilitesini daha iyi anlamayı sağlayacaktır.
