Dislocation of the scaphoid

Scaphoid Dislocation Reconstruction with Scapholunotriquetral Ligament Tenodesis

Traumatic injuries leading to complex scaphoid dislocations are uncommon. We present a successful reconstructive case after a complex intercarpal instability injury using scapholunotriquetral tenodesis without the need for Kirschner wire fixation and early controlled range of motion therapy. At 3 months, the patient had a pain-free wrist with a 100-degree arc of motion and returned to work with full functionality. A literature review was performed to describe the previously published surgical treatments of this injury pattern and compare functional outcomes.

Isolated scaphoid dislocation: A case report and review of literature

BACKGROUND

Isolated dislocations of the scaphoid are extremely rare types of injuries, commonly associated with severe ligament disruptions, and are occasionally misdiagnosed. Treatment options for dislocations of the scaphoid mainly include closed reduction, with or without internal fixation, and open reduction with ligament repair.

CASE SUMMARY

A 59-year-old male worker sustained a twisting trauma of his right wrist, caused by a moving belt while he was operating a machine. When he presented at our emergency department, the patient complained of swelling, tenderness, and restriction of movement of the right wrist. Radiographs confirmed a primary complex partial radial dislocation of the scaphoid and some chip fractures of the capitate and hamate. Closed reduction with K-wire internal fixation was performed with the assistance of arthroscopy, and an excellent prognosis was achieved.

CONCLUSION

Arthroscopy-assisted reduction is a minimally invasive method to reduce the dislocated scaphoid and maintain the blood supply.

Reconstruction of isolated scaphoid dislocation with carpal dissociation, associated with a carpal anomaly

A case is presented of isolated scaphoid dislocation with carpal dissociation in the presence of a lunato-triquetral coalition. We present the treatment and follow-up of this case. In addition, the literature on scaphoid dislocation and its treatment is reviewed. We emphasize the need to reconstruct the carpal alignment and scapho-lunate linkage.

Scaphoid dislocation associated with axial carpal dissociation during volar flexion of the wrist: a case report

We present the first report of a patient with an isolated scaphoid dislocation with axial carpal dissociation sustained during volar flexion of the wrist. The scaphoid was dislocated to the radial side of the radial styloid process and was slightly shifted to the dorsal side. It was shown that the position of the wrist played an irrelevant role for occurring scaphoid dislocation.

Isolated scaphoid dislocation associated with axial carpal dissociation: an unusual injury report

We present a report of a patient with an isolated scaphoid dislocation associated with a hyperextension and axial loading injury of the carpus required a careful and extensive clinical and radiographic evaluation leading to surgical intervention to reduce and stabilize the scaphoid and to reduce and hold internally the axial carpal injury. Knowledge of the anatomy and the potential injury patterns of the carpus will aid the hand surgeon with injury recognition and proper treatment.

[An unusual variation of luxation of the wrist: external vertical luxation. Apropos of a case. Review of the literature]

A case of lateral dislocation of the carpal scaphoid associated with a fracture of the triquetral and carpo-metacarpal dislocation of the ring and little finger is described. A thorough search of the literature failed to reveal any previous report of this combination of injuries. The dislocation was reduced by manipulation, but the scapholunate ligament required surgical repair. The results after two year was good.

Traumatic axial dislocations of the carpus

Among 1140 patients treated in the last 16 years for any type of carpal fracture, dislocation, or subluxation, 16 (1.4%) patients seen with a traumatic axial disruption of both the carpus and metacarpus were identified. Most of these were crush or blast injuries. According to the direction of instability, the cases were classified into three groups: axial-ulnar disruptions (4 patients), axial-radial disruptions (11 patients), and combined axial-radial-ulnar disruption (1 patient). Treatment consisted of open reduction and percutaneous Kirschner-wire fixation in most cases. The results were less optimistic than suggested in the literature. An average follow-up of 61 months showed that prognosis was determined more by the associated soft tissue injuries than by the carpal derangement itself. Early management of both the skeletal and soft tissue components of the injury seems most effective.
