The purpose of this study was to determine if an association exists between scaphoid-trapezium-trapezoid arthritis and lunate morphology. Plain neutral posteroanterior radiographs were evaluated for 48 patients with STT arthritis and 96 patients from a control group. Lunate type was determined using capitate-triquetrum (C-T) distance. A type I lunate was defined as a C-T distance < or =2 mm. A type II lunate was defined as a C-T distance > or =4 mm. Lunate type was recorded and compared between those with STT arthritis and a control group. The groups were similar with regard to age, gender and handedness. Type II lunates were found in 83% of cases with STT arthritis and in 64% of controls. STT OA was associated with type II lunate wrists (P = 0.02; OR = 0.35; CI: 0.15-0.82). We postulate that variations in scaphoid motion secondary to lunate morphology may contribute to the development of STT OA.
本研究的目的是确定舟月三角关节炎与月骨形态之间是否存在关联。对48例舟月三角关节炎患者和96例对照组患者的中立位后前位X线平片进行评估。使用头状骨-三角骨（C-T）间距来确定月骨类型。I型月骨定义为C-T间距≤2mm。II型月骨定义为C-T间距≥4mm。记录舟月三角关节炎患者和对照组患者的月骨类型并进行比较。两组在年龄、性别和利手方面相似。在83%的舟月三角关节炎病例和64%的对照组中发现了II型月骨。舟月三角骨骨关节炎与II型月骨手腕相关（P = 0.02；OR = 0.35；CI：0.15 - 0.82）。我们推测，继发于月骨形态的舟骨运动变化可能促成了舟月三角骨骨关节炎的发展。
