Background  There is controversy regarding the value of repair of the triangular fibrocartilage complex (TFCC). Given that an acute tear of the TFCC associated with a displaced distal radius fracture uncommonly benefits from repair, the role of repair in other settings is uncertain. Our impression is that TFCC repair is highly variable from surgeon-to-surgeon. Purpose  The purpose of this study is to determine the rate of TFCC repair in patients who had a magnetic resonance imaging (MRI) scan of the wrist obtained for ulnar-sided wrist pain, and that showed signal changes in the TFCC...

X-ray images exposed in neutral position and radiocarpally centred are essential in imaging of the distal radioulnar joint (DRUJ). The anatomic orientation of the DRUJ is favourable for acquiring transaxial scans to display its anatomy, subtle derangements, osteoarthritis and intra-articular fractures free from superpositions. The triangular fibrocartilage complex (TFCC) is the most important stabilizer of the DRUJ. Provided that a focused clinical indication is given, high-resolution images are acquired, and an intra-venous or intra-articular contrast-agent is applied, all TFCC structures and destabilizing lesions can be displayed with the use of CT and MRI...

Essex-Lopresti Lesions are rare injuries that are often missed in the acute setting. Delayed intervention may lead to chronic wrist and elbow pain and overall poor outcomes. The literature currently supports treatments that involve shortening of the ulna to reduce the relative degree of ulnar impaction, followed by attempted reduction of the distal radioulnar joint. Although such techniques may help to temporarily reduce wrist pain secondary to ulnar impaction, they do not address the proximal migration of the radius and ipsilateral radial head dislocation at the elbow...

The aim of this study was to assess distal radioulnar joint stability after unipolar ulnar head replacement for post-Darrach instability. All the patients who underwent ulnar head replacement between1999 and 2015 for post-Darrach procedure instability at our clinic were reviewed. Seven Hebert-type and two uHead (SBI/Stryker) prostheses were implanted. None of the implants were cemented. We assessed stability, pain, range of motion and strength pre- and postoperatively. The changes in the radiographic appearance between immediate postoperative and the last follow-up were determined...

BACKGROUND: The functionality of the upper extremity is decisively based on rotation of the forearm. The rotation depends on the extent of motion of the distal radioulnar joint. Rotation enables complete and focused usability of the hand in order to cope with daily activities. The configuration of the distal radioulnar joint has developed over millions of years of evolution. ANATOMIC CONDITIONS: The triangular fibrocartilage complex is the crucial stabiliser of the latter joint since osseous structures are limited...

RATIONALE: Dislocation of the distal radioulnar joint and injury to distal forearm are commonly encountered. However, delayed diagnosis or misdiagnosis has been relatively rare due to improved diagnosis and treatment. Treatment of old dislocation of radioulnar joint is challenging due to development of secondary chronic instability and difficulties in restoration of joint function. PATIENT CONCERNS: This report describes three cases of patients complained about inability to extend their little fingers...

We report a 34-year-old man who presented with ulnar wrist pain, painful click, and locking during forearm rotation following a motorcycle accident. Plain radiographs showed a loose body in the distal radioulnar joint (DRUJ), deformity of the sigmoid notch and ulnar head, and ulnar minus variant. The DRUJ deformity was assumed to be associated with physeal injury of the distal ulna during childhood. Conservative treatment with a splint and oral analgesics for 3 months failed. During DRUJ arthroscopy, osteoarthritic changes were found, and the loose body was resected using DRUJ arthroscopy...

BACKGROUND: The distal radioulnar joint (DRUJ) provides the distal link between radius and ulnar and is the centre of rotation during pronation and supination. Pronation and supination are essential in controlling the posture and optimal presentation of the hand to grasp an object. In addition, pronation and supination enable us to rotate tools when they are in the longitudinal axis of the forearm. Due to this, the DRUJ plays a central role in the performance of activities in daily life...

BACKGROUND: A stable distal radioulnar joint (DRUJ) is mandatory for the rotation and load transmission in the forearm and wrist. Salvage procedures such as the Darrach operation, Bowers arthroplasty, and the Kapandji-Sauvé procedure include the potential risk of dynamic radioulnar instability and impingement, despite stabilizing techniques addressing the soft tissues. PROSTHESES: In an attempt to stabilize the distal forearm mechanically following ulnar head resection, various endoprostheses have been developed to replace the ulnar head...

The Sauve-Kapandji (SK) procedure for distal radioulnar joint osteoarthritis have complications including pain over the proximal ulnar stump, nonunion of the fused distal radioulnar joint, and less frequently, insufficiency fracture of the distal radius. We report a case of insufficiency fracture of the radial diaphysis as a rare complication of the SK procedure.

Persistent distal radioulnar joint (DRUJ) instability after internal fixation of distal radius fractures can be managed with soft tissue or bony stabilization and prolonged immobilization. However, these strategies limit postoperative motion. To address this limitation, we report our technique of indirect ulna shortening by radial distraction followed by early mobilization and provide a case example. We use this technique in cases of persistent DRUJ instability during standard volar plating of distal radius fractures...

PURPOSE: This study defines the sigmoid notch view of the distal radius. Specifically, we tested the null hypothesis that there is no relationship between the subchondral stripe of bone seen on a sigmoid notch view of the distal radius and the articular surface of the sigmoid notch. METHODS: We used 44 wrist specimens for anatomic and fluoroscopic analysis. We measured the articular depth of the sigmoid notch from its deepest point and classified the shape of the sigmoid notch...

Background: When approaching radial head and neck fractures, the decision for ORIF, resection, or arthroplasty is often performed intraoperatively. Factors that contribute include ligamentous and bony stability, cartilage injury, mechanical alignment as well as patient factors. Recent data has suggested conventional methods may not be sufficiently sensitive in detecting Essex Lopresti injuries. Here we describe an intraoperative technique that could objectively assess proximal radio-ulnar stability with subsequent disruption of the ligamentous structures...

A 10-year-old girl presented to the emergency department with proximal radioulnar translocation and radial head fracture, after fall onto an outstretched hand. Open reduction was used to reduce and stabilise the elbow joint after which the radial head was fixated by Kirschner wires. Three months after surgery, full range of motion was regained and union of the radial head was achieved. Proximal radioulnar translocation is a rare injury which is often missed on initial radiographs. Persistent restriction of forearm rotation with seemingly normal elbow configuration must trigger to take a closer look at the relationship between the ulna, radius and distal humerus...

BACKGROUND: The Sauvé-Kapandji (SK) procedure is one of several surgical options in the treatment of distal radioulnar disorders by osteoarthritis (OA) and rheumatoid arthritis (RA). While satisfactory postoperative clinical results were obtained in most cases, instability of the proximal ulnar stump and radioulnar convergence are the most common complications. Minami et al. have developed a modification of the SK procedure that maintains the transverse diameter of the distal radioulnar joint and stabilizes the proximal ulnar stump, using a half-slip of the extensor carpi ulnaris tendon...
