BACKGROUND: The aim of this study was to investigate the outcomes in a large series of Essex-Lopresti injuries (ELIs) and to compare patients with early and late diagnoses. METHODS: Thirty-one patients with an ELI (average age and standard deviation [SD], 46 ± 10 years) who were followed for a minimum of 2 years were included in the study. Patients were grouped according to whether the ELI had been diagnosed early (on the day of the injury) or late (>4 weeks after the radial head injury)...

OBJECTIVE: To evaluate the role of the deep radioulnar ligament in the stability of the distal radioulnar joint (DRUJ). METHODS: In the study, 14 fresh cadaver upper extremities were randomly divided into two groups. After exposuring the palmar and dorsal deep distal radioulnar ligament, one group was marked as palmar deep radioulnar ligament, and the other group was marked as dorsal deep radioulnar ligament. The pronator teres and the supinator were exposed. A Kirschner wire perpendicular to the bone on Lister tubercle of radius was inserted, then another Kirschner wire on the same level of ulnar inserted when the forearm was in neural position, which was kept parallel to the first Kirschner wire...

Atraumatic acute carpal tunnel syndrome is a rare type of median nerve neuropathy caused by etiologies that increase compartment pressure in the carpal tunnel. This report describes a patient with flexor tendon abrasion as an unusual complication of distal radioulnar joint arthritis. This abrasion caused a hematoma to form in the carpal tunnel during anticoagulant treatment with apixaban, resulting in recurrent acute carpal tunnel syndrome.

Different surgical techniques have been described for chronic distal radioulnar joint instability: they are often complicated, quite invasive and may not be recommended for bidirectional instability. We describe a procedure using a radial-based extensor retinaculum strip and a capsular plication. This is a simple technique and less invasive than 'anatomic' radioulnar ligament reconstructions. We report the results of 38 patients (38 wrists) who we treated. After a minimum of 8 months we quantified the outcomes of the patients objectively by assessing ranges of motion, grip strength and clinical assessment of stability, and subjectively using questionnaires...

BACKGROUND: Coronal shear fracture type IV of the distal part of humerus is a very rare injury with articular complexity potentially leading to posttraumatic osteoarthritis. One option for surgical treatment of advanced unicompartmental radiocapitellar osteoarthritis is resurfacing radiocapitellar joint replacement. METHOD: A 62-year- old female sustained a coronal shear fracture type IV of the distal part of left humerus that was primarily treated with open reduction and internal fixation using headless compression screws...

BACKGROUND: The brachioradialis (BR) wrap technique is an option to restore the stability of the distal radioulnar joint (DRUJ). The technique capitalizes on the BR's advantageous insertion point on the radial styloid and the ability of the BR to be harvested with minimal to no deficit. The tendon can then be wrapped around the radius and ulna, tunneling under the pronator quadratus and extensor compartments and secured back into its insertion to provide stability. In this cadaveric study, we used micro-computed tomography (CT) to assess the stability restored by this procedure...

BACKGROUND: The distal radioulnar joint along with the interosseous ligament of the forearm and the proximal radioulnar joint, form a functionally integrated system responsible for the pronation-supination of the hand. The distal ulna, the so-called ulnar head, is an integral part of this system. Apart from its well-known role in forearm rotation, the ulnar head is essential in transverse load transmission through the distal radioulnar joint upon resisted elbow flexion. Autologous reconstruction of ulnar head would theoretically be beneficial with respect to prostheses...

PURPOSE: The deep component of the distal radioulnar ligament provides translational stability and rotational guidance to the forearm. However, controversy exists regarding the importance of this structure as well as the nature of its attachment to the distal ulna. We aimed to evaluate the topographic anatomy of the distal ulna attachment of both the superficial and the deep components of the radioulnar ligament and to assess the relationship between its internal and its external morphometry...

Background Damage to the interosseous membrane (IOM) can alter load transmission between the radius and ulna and decrease their axial stability. Less is known about the effect of IOM sectioning on the transverse stability between the radius and ulna. Purpose The purpose of this study was to quantify the radioulnar gapping at the distal radioulnar joint (DRUJ) during forearm rotation when the IOM was experimentally sectioned while maintaining the integrity of the distal radioulnar ligaments. Methods In 12 fresh-frozen cadaver forearms tested in a combined wrist-forearm simulator, the increase in gap between the radius and ulna, at the level of the DRUJ, was determined during cyclic forearm rotation following IOM sectioning...

BACKGROUND: Ulnar shortening osteotomy (USO) is a widely adopted procedure with excellent outcomes. However, delayed union or nonunion has occasionally been observed. The purpose of this retrospective case-control study was to identify variables affecting osseous consolidation after USO in patients with ulnar impaction syndrome. METHODS: The study included 325 patients who had undergone USO between March 2008 and March 2014. We evaluated the association between union and basic demographic factors as well as preoperative pain (assessed on a visual analog scale [VAS]), range of wrist motion, grip strength, and modified Mayo wrist score...

The distal radioulnar joint allows the human to rotate the forearm to place the hand in a desired position to perform different tasks, without interfering with the grasping function of the hand. The ulna is the stable part of the forearm around which the radius rotates; the stability of the distal radioulnar joint is provided by the interaction between ligaments, muscles and bones. The stabilizing structures are the triangular fibrocartilage complex, the ulnocarpal ligament complex, the extensor carpi ulnaris tendon and tendon sheath, the pronator quadratus, the interosseous membrane and ligament, the bone itself and the joint capsule...

The first imaging modality in patients suspected of distal radioulnar joint pathology should be conventional radiography to exclude or diagnose wrist pathology including osteoarthritis, rheumatoid arthritis, calcium pyrophosphate deposition disease, (healed) fractures, or impaction syndromes. When conventional radiography is inconclusive, high resolution 3 Tesla magnetic resonance imaging is advised. We provide a broad overview of the literature regarding the use of intra-articular contrast both with computed tomography (CTA) or magnetic resonance imaging (MRA)...

A variety of surgical techniques are used to treat the arthritic distal radioulnar joint, which is influenced by aetiology and previous procedures. Four types of ulnar head arthroplasty exist: total ulnar head, partial ulnar head, unlinked total distal radioulnar joint, and linked distal radioulnar joint. Although long-term outcome studies are sparse, short-term clinical and biomechanical studies have shown encouraging results, leading to expanded indications. Based on our experience and a literature review, patients are advised that pain is improved but minor pain is common after strenuous activity...

We describe a technique for the treatment of chronic dorsal instability of the distal radioulnar joint by creating a strong dorsal radioulnar restraint using opposing flaps from the extensor retinaculum and dorsal capsule of the radioulnar joint. This technique has been used in 18 patients and has proven to be very easy and reliable with all patients demonstrating good stability of the distal radioulnar joint at final follow-up.

The radioulnar ligament of the triangular fibrocartilage complex (TFCC), especially the deep fibers inserted at the ulnar fovea, is the key component for the distal radioulnar joint (DRUJ) stability. Traumatic injuries to the TFCC foveal insertion would cause DRUJ instability. Traditionally, arthroscopic techniques of the TFCC repair are suturing the ulnar-sided disruption peripherally to the dorsal or ulnar capsule instead of suturing the TFCC to the fovea and thus fail to restore the DRUJ stability if the TFCC is detached from the fovea...

INTRODUCTION: Pathological factors may cause significant distal radioulnar joint (DRUJ) dislocation, which is a rare clinical entity in orthopedic literature, and corresponding treatments are not uniform. PRESENTATION OF CASE: We describe the case of a DRUJ dislocation caused by giant cell tumour of tendon sheath (GCTTS) in wrist. At surgery, the stabilization of DRUJ was constructed by using mini-plate-button after removal of intraoperative removal of the tumor...
