Jersey finger describes the rupture of the flexor digitorum profundus (FDP) tendon at its insertion into the distal phalanx. In the absence of an evidence-based approach to tensioning during secondary repair, we aimed to devise a novel method to determine the required tendon length pre/intraoperatively. We measured anatomical landmarks, associated with the FDP tendon, on dissected cadavers, to assess whether these can be used to estimate tendon segment lengths. Eight cadaveric hands were dissected. Three measurements from the distal lumbrical origin to (1) FDP insertion, (2) the distal end of A1 (Annular 1 pulley), and (3) the proximal end of A1 were recorded for digits II-V. Relative ratios for measurement 1 were consistent for all digits, compared to digit III. Linear regression analysis confirmed a strong correlation for measurement 1 between digit II (R=0.97) and digit IV(R=0.97) compared to digit III across all specimens. Digit III distal lumbrical origin to FDP insertion measurements could facilitate the estimation of the required graft length for digit II or IV during secondary repair. This is a level IV study, providing proof of concept for a novel method of tendon tensioning.
“泽西手指”指的是指深屈肌腱在其插入远节指骨处的断裂。在二次修复过程中缺乏基于证据的张力调节方法的情况下，我们旨在设计一种新方法，在术前/术中确定所需的肌腱长度。我们在解剖的尸体上测量了与指深屈肌腱相关的解剖标志，以评估这些标志是否可用于估计肌腱段的长度。解剖了八具尸体的手。记录了从指深肌起点到（1）指深屈肌腱插入点、（2）A1（第一环状滑车）远端、（3）A1近端的三个测量值，用于示指至小指。与中指相比，所有手指测量值1的相对比率是一致的。线性回归分析证实，在所有标本中，与中指相比，示指（R=0.97）和环指（R=0.97）测量值1之间存在很强的相关性。中指指深肌起点到指深屈肌腱插入点的测量值有助于估计二次修复过程中示指或环指所需移植物的长度。这是一项IV级研究，为一种新的肌腱张力调节方法提供了概念验证。
