Amaç
Bu çalışmanın amacı, birinci karpometakarpal (KMK) eklem osteoartriti olan hastalarda tenar kasların ultrasonografik kalınlığını incelemek ve erken ile ilerlemiş evreleri karşılaştırarak parmak ve el kavrama kuvvetini değerlendirmektir.
Yöntem
Bu kesitsel çalışmaya, erken veya ilerlemiş evre birinci KMK eklem osteoartriti tanısı konmuş, 50-80 yaş aralığında toplam 34 kadın hasta dahil edildi. Hastalar erken evre (Eaton evre 1-2) veya ilerlemiş evre (Eaton evre 3-4) olarak sınıflandırıldı. abduktor pollicis brevis (APB), opponens pollicis (OPP) ve birinci dorsal interosseöz (FDI) kaslarının kalınlıkları, hem dominant hem de non-dominant ellerde ultrason kullanılarak ölçüldü. El kavrama kuvveti el dinamometresiyle, parmak kavrama kuvveti ise hidrolik pinçmetre ölçer ile değerlendirildi.
Bulgular
APB, OPP ve dominant taraftaki FDI kas kalınlıkları ile parmak kavrama kuvveti erken evre hastalarda anlamlı olarak daha yüksekti (p<0,05). El kavrama kuvvetinde ise anlamlı bir fark saptanmadı. Dominant OPP kalınlığı, parmak kavrama kuvveti ile pozitif korelasyon gösterirken (r=0,382, p=0,026), APB kalınlığı yaş ve ağrı şiddeti ile negatif ilişki içindeydi.
Sonuç
Birinci KMK osteoartritinde kas kalınlığı ve parmak kavrama kuvveti, hastalığın ilerlemesiyle birlikte azalmaktadır. Tenar kaslardaki değişikliklerin ultrasonografi ile erken tespiti, başparmak fonksiyonunu korumaya yönelik tedavi rehberliğine yardımcı olabilir.
