“…There is inconsistency in the literature about this finding. Some show increased carpal tunnel cross section areas in the carpal tunnel syndrome group (22), but some have found no difference or smaller carpal tunnel cross section areas in carpal tunnel patients (10,13,14,23). Carpal tunnel areas measured in our series were found to be larger than the control group in all sections but the difference was found to be statistically insignificant, and therefore this statistically significant (p<0.0016).…”

ABSTRACTaIM: The aim of this study was to try to find parametric ratios for the diagnosis and pathophysiology of carpal tunnel syndrome using MR. MaterIaL and MetHOds:Dominant side wrist MRI examinations of 27 female carpal tunnel patients and 21 normal females were compared. The carpal tunnel contents area / carpal tunnel cross section area ratio was defined, analysed and discussed with the literature. resuLts: Carpal tunnel contents / wrist area ratios of the carpal tunnel patients were measured and compared with the control group. This comparison revealed that the proportion of the contents of the carpal tunnel is increased in the carpal tunnel syndrome patients. Palmar bowing was found to be increased and median nerve cross section area was found to be increased at the proximal entrance of the carpal tunnel.cOncLusIOn: As Phalen has postulated, the volume of the contents of the carpal tunnel were found to be increased in the carpal tunnel syndrome patients. Carpal tunnel cross section areas remained the same with the control group. This increase can be demonstrated by MRI imaging which can provide an evidence for the pathophysiology of carpal tunnel syndrome.keywOrds: Carpal tunnel syndrome, Area measurement, Ratio ÖZ aMaÇ: Bu çalışmanın amacı, el bileği MR incelemesiyle tespit edilen karpal tünel kapsamı/karpal tunel alanı oranları ile karpal tunel sendromuna diagnostik ve patofizyolojik bir yaklaşımda bulunmaktır. yÖnteM ve gereÇLer: 27 karpal tunel hastası kadın ile dominant el bileği MR incelemesi yapılan 21 kadından oluşan kontrol grubunun el bilek MR ları karşılaştırılmıştır. Karpal tunel kapsamı / karpal tunel alanı oranı tanımlanarak bu oran, median sinir alanı ve transverse karpal ligamentteki palmar yaylanma ölçülerek analiz edilmiştir.BuLguLar: Seride karpal tunel kapsamı/karpal tunel alanı oranında karpal tunel sendromlu hastalarda karpal tunel kapsamı lehinde istatistiksel olarak anlamlı bir artış tespit edilmiştir. Hastalarda karpal tunel proksimal girişinde ölçülen median sinir kesit alanlarında ve transvers karpal ligament palmar yaylanmasında da istatistiksel olarak anlamlı bir artış bulunmuştur. sOnuÇ: Karpal tunel sendromlu hastalarda Phalen'in öne sürdüğü gibi karpal tunel kapsamında kronik travmaya bağlı bir artış tespit edilmiştir. Bu kapsam artışına karşılık karpal tunel yüzey alanlarında anlamlı bir artış tespit edilmemiştir. Bu bulgu MR ile gösterilebilmektedir ve karpal tunel sendromunun fizyopatolojisinin anlaşılması konusunda bir kanıt olabilmektedir.anaHtar sÖZcÜkLer: Karpal tunel sendromu, Alan ölçümü, Oran

“…Individuals with high blood pressure require higher intracarpal tunnel pressure elevation to decrease blood flow and impair nerve function (78). Whether large or small carpal tunnel areas increase the risk for carpal tunnel syndrome is a disputed issue (79,80). It may be that the residual volume plays an important role (81).…”

“…Smaller carpal canal area has been associated with CTS in some studies (Bleecker, Bohlman, Moreland, & Tipton, 1985). However, others have failed to find an association between wrist circumference and CTS (Winn & Habes, 1990).…”
