Study Overview

Brief Summary

The distal ulna is an important weight-bearing component of the wrist joint and an essential element of the forearm articulation. After injury, significant residual malalignment or deformity of the distal ulna and deficiency of its ligamentous support have a deleterious effect on grip strength and forearm rotation.

Although the best treatment option for displaced distal ulnar fracture remains a subject of debate, most surgeons aim for anatomical reduction and stable fixation to avoid disruption of the distal radioulnar joint.

The investigators will assess clinical and radiological results of fixation of displaced distal ulna fractures in adults by flexible intramedullary nail.

Detailed Description

Fractures of the distal ulna usually occur in association with distal radius fractures.

Isolated distal ulnar fracture is an uncommon upper limb injury. It is usually the consequence of a direct blow against the soft tissue-deficient ulnar border.

Injuries to the distal ulna can lead to derangement of the distal radioulnar joint (DRUJ), subsequently resulting in pain from incongruity or ulnocarpal impaction, limitation of forearm rotation due to scarring, and weakness secondary to instability of the joint under load.

Isolated fractures of the distal third of the ulnar shaft can be treated successfully by conservative if not significantly displaced and if rotational malalignment is not present. Fractures with significant displacement or those with rotational malalignment (displaced spiral fracture patterns) are best be treated by osteosynthesis and functional rehabilitation in order to prevent loss of forearm rotation.

Outcomes

Primary Outcomes

Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire scores

Time Frame: 6 months postoperative

Self-administered region-specific outcome instrument developed as a measure of self-rated upper-extremity disability and symptoms. The DASH consists mainly of a 30-item disability/symptom scale, scored 0 (no disability) to 100

Radiological evaluation

Time Frame: 6 months postoperative
