PURPOSE: Using a novel technique, we assess and describe the distal radioulnar joint (DRUJ) anatomy. The purpose of this study was to provide the anatomic dimensions of the DRUJ and to evaluate contralateral symmetry. METHODS: Computed tomography images of 100 cadaveric forearms were obtained. Three-dimensional models of the radius and ulna were generated and evaluated using 3-dimensional modeling software. Measurements of the radius of curvature of the sigmoid notch (SN) and ulnar head (UH), as well as the length of the SN and volar and dorsal lips were performed in the axial and coronal sequences...

This study correlated morphologic abnormalities of idiopathic carpal tunnel syndrome (CTS) with the severity of CTS using 3-T magnetic resonance imaging (MRI). The relationship of the severity of CTS and the cross-sectional area of the median nerve (CSA) was assessed at several levels. Seventy wrists of 35 patients (27 women and 8 men) with unilateral idiopathic CTS underwent nerve conduction study and 3-T MRI of the wrist. The CSA at 4 levels (distal radioulnar joint, body of scaphoid, tubercule of scaphoid, and hook of hamate) and the thickness of the transverse carpal ligament at 3 levels in both affected and unaffected hands were measured using 3-T MRI and correlated with the severity of CTS assessed with distal motor latency...

The importance of foveal repair of the triangular fibrocartilage complex (TFCC) on stability of the distal radioulnar joint (DRUJ) has been emphasized with increasing knowledge of the anatomy and biomechanics of the TFCC and DRUJ. Although both open and arthroscopic techniques have been described for improving DRUJ stability, there has been a marked evolution of arthroscopic TFCC repair technique with successful clinical outcome. Recently, an arthroscopic trans-osseous technique has been described to repair foveal tears of the TFCC...

OBJECTIVES: The diagnosis of distal radioulnar joint (DRUJ) instability is clinically challenging. Computed tomography (CT) may aid in the diagnosis, but the reliability and normal variation for DRUJ translation on CT have not been established in detail. The aim of this study was to evaluate inter- and intraobserver agreement and normal ranges of CT scoring methods for determination of DRUJ translation in both posttraumatic and uninjured wrists. MATERIALS AND METHODS: Patients with a conservatively treated, unilateral distal radius fracture were included...

Treatments for acute distal radioulnar joint (DRUJ) instability with distal radius fracture vary from conservative to operative treatment, although it seems to be no consensus regarding which treatment is optimal. This prospective randomized study was designed to compare the clinical outcomes for operative and conservative treatment of acute DRUJ instability with distal radius fracture, according to the presence or absence and type of ulnar styloid process fracture and the degree of its displacement. Between July 2008 and February 2013, we enrolled 157 patients who exhibited an unstable DRUJ during intraoperative manual stress testing (via the ballottement test) after fixation of the distal radius...

Combination of the Galeazzi fracture and dislocation of the elbow joint in same extremity is very rare. In this article, we report a 26-year-old male patient with a posterolateral dislocation of the elbow and ipsilateral volar type Galeazzi fracture. We performed closed reduction for the elbow dislocation during admission to the emergency department. Patient was taken to the operating room in the sixth hour of his application to emergency department and open wound on the ulnovolar region of the wrist was closed primarily after irrigation and debridement...

BACKGROUND: To evaluate results of a technique for treating neglected epiphyseal injuries of the distal radius with ulnar impaction. MATERIALS AND METHODS: This retrospective study involved six cases (four males; two females), all of whom sustained the primary injury during childhood (range 9-12 years of age). All presented with wrist deformity and ulnar-sided wrist pain. They were managed with osteotomy of the distal radius, osteotomy and shortening of the ulna, harvesting the bone grafts, and distal radioulnar joint (DRUJ) reduction performed simultaneously through a dorsal midline approach...

BACKGROUND: Previous work from this laboratory has evidenced the biomechanical role of forearm osseoligamentous structures in load transfer of applied forces. It has shown that forces transmitted across the distal radioulnar joint (DRUJ) and proximal radioulnar joint (PRUJ) are similar, though not identical, under axial loading conditions. The purpose of the study was to assess the articulating surface areas of the radioulnar joints and the volumes of the forearm bones addressing the hypothesis that there may be anatomic adaptations that reflect the biomechanical function of the integrated forearm unit...

Essex-Lopresti injuries (ELIs) are characterized by fracture of the radial head, disruption of the forearm interosseous membrane, and dislocation of the distal radioulnar joint. This injury pattern results in axial and longitudinal instability of the forearm. Initial radiographs may fail to reveal the full extent of the injury, and therefore diagnosis in the acute setting requires a high index of suspicion. Early recognition and treatment are preferred as failure to fully treat the problem may result in chronic wrist pain from ulnar abutment or chronic elbow pain from radiocapitellar arthrosis...

Radial club hand may be congenital or acquired; radial deviation of the hand is usually found, associated with palmar flexion-pronation and treatment of severe forms of radial club hand is often difficult. Here we present a case of reconstruction of a severe postraumatic radial club hand with a free fibular osteoseptocutaneous flap and Sauve-Kapandji procedure in a 28-year-old man. The patient had a radial deviation of the wrist and right upper limb shortening as a result of an infected pseudarthrosis of the radius...

The distal radioulnar joint (DRUJ) allows forearm rotation and load transmission across the wrist. Post-traumatic and degenerative joint disease of DRUJ may cause pain and disability. Deficiency of the soft tissue or bony supports may result in DRUJ instability. Various techniques have been developed to address arthritis and / or instability of the DRUJ. A comprehensive review of the spectrum of surgical techniques and arthroplasty options is presented. The concepts of these procedures are discussed in detail, with a focus on special points of interest to optimise outcomes and to avoid complications...

This study describes a minimally invasive procedure for stabilization of the distal radioulnar joint, using a suture-button construct placed percutaneously in the direction of the distal oblique bundle in the distal interosseous membrane. In five cadaveric specimens, placement of the suture-button suspension system reduced dorsal displacement of the radius in an unstable distal radioulnar joint to baseline values, both in neutral position and in pronation and supination. These results indicate the possibility of minimally invasive treatment for distal radioulnar joint instability...

A precise medical history and specific symptom-oriented clinical tests of the wrist joint should always precede any radiological, computed tomography (CT) or magnetic resonance imaging (MRI) diagnostics. In many cases, specific clinical tests of the wrist joint allow at least a preliminary diagnosis, which can be supported by standard radiography using correct projections. A systematic approach is recommended covering the radiocarpal, midcarpal, ulnocarpal and distal radioulnar joints. Exact identification of the palpable anatomic landmarks is mandatory for correct application and interpretation of the various clinical tests...

OBJECTIVE: Arthroscopic decompression (wafer procedure) of the ulnocarpal compartment in patients with ulnar impaction syndrome. INDICATIONS: The arthroscopic wafer procedure is recommended in ulnar-plus situations with up to 3 mm length-excess. To perform this procedure the ulnar head needs to be accessible for the burr through a pre-existing, impaction-related, centroradial lesion of the triangular fibrocartilage complex (TFCC). The additional presence of a distal radioulnar joint (DRUJ) type C confirms the indication...
