Background: Isolated distal radioulnar joint (DRUJ) dislocations without associated fracture are very rare entities. A few mechanisms of injury were reported in the literature with dorsal(posterior) dislocation being more common than the volar (palmar, anterior) dislocation. Case report: A 26-year-old male, manual laborer presented to our emergency department (ED) 24 hours post-self-inflected injury with right wrist pain, deformity, and decreased range of motion (ROM). The physical examination showed bruising over the dorsal ulnar side of the wrist, loss of the ulnar styloid bony prominence, abnormal volar fullness of the wrist, and gutter deformity on the dorsal aspect of the distal forearm and wrist. The diagnosis was confirmed by comparative radiographs which were followed by closed reduction and immobilization in the below-elbow cast in pronation for 4 weeks. Conclusion: Timely accurate diagnosis and conservative treatment with favorable outcome necessitate a proper history on the mechanism of injury with a thorough physical examination, accurate radiographic positioning, and true lateral view.

Untreated distal radioulnar joint (DRUJ) injuries can give rise to long lasting complaints. Although common, diagnosis and treatment of DRUJ injuries remains a challenge. The articulating anatomy of the distal radius and ulna, among others, enables an extensive range of forearm pronosupination movements. Stabilization of this joint is provided by both intrinsic and extrinsic stabilizers and the joint capsule. These structures transmit the load and prevent the DRUJ from luxation during movement. Several clinical tests have been suggested to determine static or dynamic DRUJ stability, but their predictive value is unclear. Radiologic evaluation of DRUJ instability begins with conventional radiographs in anterioposterior and true lateral view. If not conclusive, CT-scan seems to be the best additional modality to evaluate the osseous structures. MRI has proven to be more sensitive and specific for TFCC tears, potentially causing DRUJ instability. DRUJ instability may remain asymptomatic. Symptomatic DRUJ injuries treatment can be conservative or operative. Operative treatment should consist of restoration of osseous and ligamenteous anatomy. If not successful, salvage procedures can be performed to regain stability.

Radioulnar Joint

Introduction: Ulnar volar dislocation (UVD) is a very rare entity. Due to rarity of condition, usually, it’s misdiagnosed at emergency departments and management of this clinical entity is not well studied. Here, we report a case of UVD impressing diagnostic challenge, indication of treatment, and follow-up. Case Report: A 29-year-old man presented to orthopedic outpatient service with complaining of the right wrist pain. He had an assault history 3 days before. In the emergency department, he had been diagnosed as wrist sprain. Splint and pain killers were prescribed. Due to increase of pain, he admitted to orthopedics. He was diagnosed UVD. Under general anesthesia, joint was reduced with forced pronation maneuver. After 3 weeks immobilization period, magnetic resonance images revealed partial injury of triangular fibrocartilage complex then splint removed and rehabilitation initiated. Over than 24 months, he is doing well without movement limitation and wrist strength impairment. Conclusion: For prevention misdiagnosis of UVD, physical examination is very important. Forearm rotation limitation with pain in the wrist should be indicative for distal radioulnar joint injury. Physical examination should be supported with proper evaluation of suitable radiographs. After reduction of joint, magnetic resonance images give clues about ligamentous injury. Our case supports the importance of rigorous physical examination and evaluation of radiographs for wrist injury. In the presence of partial injury of ligaments, the condition can be treated with shorter periods of immobilization and early rehabilitation. Keywords: Wrist pain, ulnar volar dislocation, distal radioulnar joint, forearm rotation.

The advantage of preserving the distal radioulnar joint in wrist disarticulation is that full forearm rotation is possible if the joint is intact, which improves the capability of the amputee. The Sauvé-Kapandji procedure has been performed to treat rheumatoid or post-traumatic chronic instability and/or arthritis of the distal radioulnar joint. We report a patient with wrist disarticulation that presented to us with limited supination of the wrist due to an injured distal radioulnar joint. We performed the Sauvé-Kapandji procedure, and the patient could regain functional supination of the forearm without losing the ulnar styloid flare that improved prosthetic suspension. This case suggests that the Sauvé-Kapandji procedure can be performed to maintain the advantage of wrist disarticulation even when the initial trauma involves an irreparable injury of the distal radioulnar joint.

Objective This study was performed to determine the prevalence of triangular fibrocartilage complex (TFCC) injuries as shown by 3.0T magnetic resonance imaging (MRI) in patients with distal radius fractures. Methods In total, 57 patients with distal radius fractures underwent 3.0T MRI examinations to observe the incidence of TFCC injuries after manual reduction and cast fixation. The fracture type was categorized by the AO classification, and the TFCC injury pattern was evaluated using the Palmer classification. The correlation between the location of the TFCC injury and the distal radius fracture pattern, distal radioulnar joint instability, or ulnar styloid fracture was analyzed. Results Fifty-five TFCC injuries were diagnosed. There was no significant relationship between the TFCC injury pattern and the type of distal radius fracture, distal radioulnar joint instability, or ulnar styloid fracture. Conclusions This study revealed a high prevalence of TFCC injuries in patients with distal radius fractures. The 3.0T MRI examination helps to assess TFCC injuries in patients with distal radius fractures. Clinical Trial Registration ChiCTR1800017101.

Four patients with dorsal dislocation of the distal radioulnar joint and ulnar styloid malunion had corrective osteotomy of the ulnar styloid. Dislocation of the distal radioulnar joint was reduced in three of four patients. Subluxation persisted in the remaining patient. Wrist function improved in all patients. These results support the contention that a displaced ulnar styloid fracture with distal radioulnar joint dislocation should be reduced and internally fixed. Corrective osteotomy is recommended for malunion of the ulnar styloid associated with dislocation of the distal radioulnar joint.

Triangular Fibrocartilage

Traumatic hypersupination injury of the distal radioulnar joint is a rare injury, and occurs when sufficient supination force is applied to the joint so as to tear the volar radioulnar ligament, resulting in separation of the triangular fibrocartilage complex, and subluxation of the tendon of extensor carpi ulnaris. This allows the distal ulna to rotate such that the ulnar styloid comes to lie adjacent to the ulna notch of the radius. Treatment of this injury requires manipulation of the joint, under anaesthesia or sedation. We describe a case where posttraumatic radiological investigation of a patient with an anatomical variation of the wrist when in supination resembled a traumatic hypersupination injury of the distal radioulnar joint. A review of the literature has revealed this to be the first reported case of this type.

A Prospective Study

In a prospective study we evaluated the results of 272 distal radial fractures by their involvement of the distal radioulnar joint. Impaired function following altered anatomy at the distal radius can be explained by dysfunction of the distal radioulnar joint. Ulnar styloid avulsions contribute to a poorer result because of their effect on distal radioulnar joint function.
