Abstract

Because of the frequent misdiagnosis of the carpal injury, the orthopedic surgeon must know the mechanism of injury and exact radiological interpretation. We had encountered 114 cases of carpal injury, in which carpal fracture, carpal dislocation and instability were analysed by radiological examination. The following results were obtained: 1. In 75 carpal bone fractures, the most common fracture was scaphoid fracture (64 cases), the next com- mon one was triangular fracture (4 cases). 2. Among the 64 scaphoid fractures, the waist portion was the most frequent site (45 cases) and the least was tubercle fracture (2 cases). 3. Of the carpal bone fractures, the fresh fracture was 48 cases (64%) and old one was 27 cases (36%), these showed sclerosis, cystic change, and degenerative change in radiological examination. 4. In 14 carpal dislocations, perilunar dislocation was 2.5 times move common than lunate dislocation, and the trans-scaphoid perilunar dislocation was the most common dislocation. 5. Carpal instability was 25 cases. These were dorsiflexion instability, navicular rotary subluxation, and pal- mar-flexion instability. The most common instability was dorsiflexion instability.
