Isolated scaphoid dislocation: A case report and review of literature

Figure 1 Initial radiographs demonstrated primary complex partial radial dislocation of the scaphoid; The computed tomography scans demonstrated the chip fractures of the capitate and hamate. A: Posteroanterior and lateral; B: Computed tomography scans.

Figure 2 Arthroscopy confirmed complete disruption of the scapholunate and radioscaphocapitate ligaments, and scapholunate diastasis was Geissler grade IV. S: Scaphoid; SL: Scapholunate ligament.

Figure 3 Postoperative radiographs showed internal fixation with K-wires. A: Posteroanterior; B: Lateral.

Figure 4 At the 6-mo follow-up, the action of all sides of the carpal bone. A: Normal flexion; B: Slight restriction of extension; C: Supination; D: Pronation. These four movements were observed compared to the contralateral side.

Figure 5 At the 6-mo follow-up, radiographs revealed neither avascular necrosis of the proximal pole of the scaphoid nor scapholunate diastasis. A: Posteroanterior; B: Lateral.

Figure 6 Classifications of isolated scaphoid dislocation. 1: Primary; C: Complex; D: Dorsal; P: Partial; Pr: Palmar radial; Ps: Palmar straight; Pu: Palmar ulnar[2]; R: Pure radial; S: Simple; T: Total.
