Using radiographs of a cross section of patients, measurements of phalanges were done to aid in surgical planning for distal interphalangeal joint (DIPJ) arthrodesis using a headless compression screw. Measurements were performed of the distal and middle phalanx of all fingers and the proximal and distal phalanx of the thumb. Three independent reviewers measured 50 patients. The average measurements (in mm) of anteroposterior (AP) dimensions were as follows: for the thumb P1 and P2: 5.7 and 5.5, lateral 4.2 and 3.5; for the index P2 and P3 AP: 4.2 and 3.3, lateral 2.1 and 1.8; for the long P2 and P3 AP: 4.5 and 3.5, lateral 2.2 and 1.8; for the ring P2 and P3 AP: 4.3 and 3.1, lateral 1.8 and 1.7; and for the small P2 and P3 AP: 3.7 and 2.2, lateral 1.8 and 1.5. Careful surgical planning by measuring the involved digit and knowledge of screw size is paramount to avoid complications from DIPJ arthrodesis with a compression screw.
利用患者横断面的X光片,对指骨进行测量,以辅助使用无头加压螺钉进行远侧指间关节(DIPJ)融合术的手术规划。对所有手指的远节指骨和中节指骨以及拇指的近节指骨和远节指骨进行测量。三位独立的评估者对50名患者进行了测量。前后(AP)尺寸的平均测量值(以毫米为单位)如下:拇指的近节指骨(P1)和远节指骨(P2):前后径分别为5.7和5.5,左右径分别为4.2和3.5;示指的中节指骨(P2)和远节指骨(P3)前后径:4.2和3.3,左右径2.1和1.8;中指的中节指骨(P2)和远节指骨(P3)前后径:4.5和3.5,左右径2.2和1.8;环指的中节指骨(P2)和远节指骨(P3)前后径:4.3和3.1,左右径1.8和1.7;小指的中节指骨(P2)和远节指骨(P3)前后径:3.7和2.2,左右径1.8和1.5。通过测量受累手指并了解螺钉尺寸进行仔细的手术规划对于避免使用加压螺钉进行DIPJ融合术的并发症至关重要。
