Extension block splinting (EBS) at the proximal interphalangeal joints of the fingers is a common technique for both primary treatment of reduced dorsal dislocations/fracture-dislocations at that joint and as a rehabilitation method following open reduction of such injuries. It is seldom realized that the method is a classic example of two orthopedic principles: stable arc splinting and early protected motion. As a primary treatment technique, following reduction of the dislocation, EBS is exemplary for an ideal group of cases, competitive for a marginal group of cases, and often unsatisfactory for a questionable group of cases. Demarcation between the groups is made, and the technique of EBS is reviewed.
手指近端指间关节的伸展块夹板固定术（EBS）是一种常用技术，既用于该关节背侧脱位/骨折脱位复位的初始治疗，也作为此类损伤切开复位后的康复方法。很少有人意识到，该方法是两个骨科原则的经典示例：稳定弧夹板固定和早期保护性活动。作为一种初始治疗技术，脱位复位后，EBS在理想病例组中堪称典范，在边缘病例组中有竞争力，而在可疑病例组中往往不尽人意。对各病例组进行了划分，并对EBS技术进行了回顾。
