Successful Closed Reduction of a Lateral Elbow Dislocation

Kenya Watanabe et al. Case Rep Orthop. 2016.

Abstract

In this report, we present a case of lateral elbow dislocation treated with closed reduction. Lateral elbow dislocation is rare, and a closed reduction is reported with even less frequency. The reduction can be hindered by swelling and soft tissue interposition, and we describe the use of a nonoperative reduction technique performed under mild sedation with early physiotherapy to avoid joint stiffness. No additional complication was observed, and the normal range of elbow movement and function was obtained by early physiotherapy.

Figures

Figure 1
Figure 1
Anteroposterior and lateral radiographs of the elbow revealed lateral convergent displacement of the radius and ulna relative to the humerus without fracture signs.
Figure 2
Figure 2
During reduction maneuver, the image intensifier revealed that only the ulnohumeral joint was reduced.
Figure 3
Figure 3
Postreduction radiographs revealed no fractures.
Figure 4
Figure 4
Postreduction radiographs revealed obvious varus and valgus instability of the joint. However, redislocation was not observed in the range of motion from 30° to 90°.
Figure 5
Figure 5
The elbow arthrography revealed a complete tear of the medial collateral ligament and a suspected partial tear of the lateral collateral ligament.
Figure 6
Figure 6
After 8 weeks, the elbow range of motion was from 0° to 125°, supination to 90°, and pronation to 90°.
Figure 7
Figure 7
Eight weeks after the trauma, radiographs revealed mild calcification around the anterior articular capsule, medial collateral ligament, and lateral collateral ligament.

Decreased velocity and prolonged latency of the ulnar nerve improved steadily.
