PURPOSE: To investigate the reduction accuracy of 3-dimensional planned single-cut osteotomies (SCOTs) of the forearm that were performed using patient-specific guides. METHODS: A retrospective analysis of SCOTs performed between 2012 and 2014 was performed. Ten patients (age, 15-59 years) with 6 malunions of the ulna and 6 malunions of the radius were identified. The reduction accuracy was assessed by comparing the 3-dimensional preoperative plan of each osteotomy with the superimposed bone model extracted from postoperative computed tomography data...

INTRODUCTION: Radioscapholunate (RSL) fusion is typically performed following wrist trauma. It addresses the pain caused by radiocarpal osteoarthritis but reduces the wrist's mobility. The objective of this study was to determine the long-term clinical and radiological outcomes of this procedure. MATERIALS AND METHODS: This was a retrospective study of all wrists operated for RSL fusion in our surgery unit over a 12-year period. The clinical analysis consisted of joint amplitudes, grip strength, pain (VAS) and functional scores (PRWE, QuickDash, Mayo Wrist Score)...

Distal radioulnar joint (DRUJ) instability is a rare but disabling problem. Surgical treatment remains a challenge. The advent of arthroscopic techniques has helped to rebuild the triangular fibrocartilaginous complex (TFCC), especially its deep part. However, isolated TFCC damage is not responsible for instability. Its repair is sometimes not sufficient to restore DRUJ stability, or the chronicity of the injury prevents its direct repair. Open surgical procedures still have a role in these cases. They require a detailed knowledge of the various stabilizers of the DRUJ...

PURPOSE: The radius bone has a slight dorsoradial bow that allows for full forearm pronosupination around the ulna. However, radial malunion can lead to reversal of the radial bow and subsequent volar instability of the distal radioulnar joint (DRUJ), predominantly in supination. This study assessed the outcomes of corrective radial osteotomy for volar DRUJ instability after radial malunion in children. METHODS: The charts of 7 children (2 boys and 5 girls) treated with corrective radial osteotomy for volar DRUJ instability after a radius fracture or deformity were reviewed...

BACKGROUND: Historically, failed conservative treatment for irreparably damaged distal radioulnar joints (DRUJs) is treated via distal ulnar resection or DRUJ fusion; complications include disabling painful convergence of the radius and ulnar stump during lifting Various treatments for radioulnar impingement include distal radioulnar Achilles tendon allograft interpositional arthroplasty. This technique does not adequately prevent radioulnar impingement and we explore an alternative treatment...

Distal radioulnar joint (DRUJ) instabilities are common and often combined with other injuries of the interosseous membrane and/or the proximal radioulnar joint. Once they are diagnosed and the treatment is chosen, physiotherapists have limited choices due to the lack of validated protocols. The benefits of proprioception and neuromuscular rehabilitation have been brought to light for the shoulder, knee and ankle joints, among others. However, no program has been described for the DRUJ. The purpose of this article is to study the muscular elements responsible for active DRUJ stability, and to propose a proprioceptive rehabilitation program suited to this condition...

BACKGROUND: Forearm immobilization techniques are commonly used to manage distal radius, scaphoid, and metacarpal fractures. The purpose of our study was to compare the degree of rotational immobilization provided by a sugar-tong splint (STS), short arm cast (SAC), Munster cast (MC), and long arm cast (LAC) at the level of the distal radioulnar joint (DRUJ), carpus, and metacarpals. METHODS: Seven cadaveric upper extremity specimens were mounted to a custom jig with the ulnohumeral joint fixated in 90° of flexion...

BACKGROUND: The deep portion of the distal radioulnar ligaments (DRUL) inserts on the ulnar fovea and is the most important stabilizer of the distal radioulnar joint (DRUJ). Ulnar styloid base fractures that include the ulnar fovea may cause DRUJ instability. METHODS: DRUJ stability in pronosupination was evaluated in 12 fresh-frozen upper extremities (4 female) aged 52 to 68 years (mean: 58.8 years) using a custom fixture, which allowed free rotation of the radius around the fixed ulna...

Among the various reasons for chronic posttraumatic ulnar-sided wrist pain, instability of the distal radioulnar joint (DRUJ) has recently received major attention and finally achieved fundamental progress in understanding thanks to anatomic and biomechanical studies. This has resulted in more physiological and successful treatment methods compared with the historic options. One and the most dramatic surgical technique consists in the replacement of the main ligamentous stabilizer of the DRUJ, the so-called triangular fibrocartilage, with a tendon graft...

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...
