The volumes enclosed by each of 108 hands in 54 rheumatoid arthritis patients were calculated using individual joint measurements. The difference between the flexion and extension volumes is the 'working space' of the hand. Correlations between the working space and parameters of stiffness, pain, deformity, movement, grip and functional disability were performed. The average working space volume was 4921 cc in rheumatoid patients with no visible hand deformity and 1154 cc in the presence of combined finger deformities (P < 0.005). The loss in volume was due mainly to loss of extension. The Patient Evaluation Measure and the Functional Disability Score were significantly related to changes in the working space (P < 0.05). The concept of the working space of the hand may aid the assessment of the rheumatoid hand and help surgical decision-making.
通过对54例类风湿性关节炎患者的108只手进行逐个关节测量，计算出每只手的容积。屈伸容积之差即为手的“工作空间”。对工作空间与僵硬、疼痛、畸形、活动、握力及功能残疾等参数进行相关性分析。无明显手部畸形的类风湿患者平均工作空间容积为4921立方厘米，合并手指畸形时为1154立方厘米（P<0.005）。容积减少主要是由于伸展功能丧失。患者评估指标和功能残疾评分与工作空间变化显著相关（P<0.05）。手部工作空间的概念可能有助于类风湿性手部病变的评估及手术决策。
