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 The purpose of this article was to review the anatomy, kinematics of the distal radioulnar joint (DRUJ), and to discuss definition, classification, and diagnosis of DRUJ instability. Methods A biomechanical perspective on physical examination of DRUJ ballottement test was documented. Physiological dynamic DRUJ translation and differences of the translation following sequential ligament sectioning and changes in different forearm and wrist positions were demonstrated. The clinical significance of each ligament's contribution to joint stability in specific wrist positions was addressed...

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...

PURPOSE: Certain distal ulna fractures may contribute to distal radioulnar joint (DRUJ) instability. We hypothesized that residual distal ulna translation could affect DRUJ stability by slackening the distal interosseous membrane (DIOM). We aimed to test this hypothesis in a cadaver model. METHODS: We created an ulnar translated distal ulna fracture model in 6 cadavers. Dorsal and palmar displacements of the ulna relative to the radius were measured and DRUJ instability was staged under the following conditions: (1) 0-, 2-, and 4-mm ulnar translation of the distal ulna with an intact triangular fibrocartilage complex (TFCC) and DIOM; (2) 0-, 2-, and 4-mm translations with TFCC divided and an intact DIOM; and (3) a 0-mm translation with TFCC and DIOM divided...

AIMS: The aims of this study were: firstly, to investigate the influence of the thickness of cartilage at the sigmoid notch on the inclination of the distal radioulnar joint (DRUJ), and secondly, to compare the sensitivity and specificity of MRI with plain radiographs for the assessment of the inclination of the articular surface of the DRUJ in the coronal plane. PATIENTS AND METHODS: Contemporaneous MRI images and radiographs of 100 wrists from 98 asymptomatic patients (mean age 43 years, (16 to 67); 52 male, 53%) with no history of a fracture involving the wrist or surgery to the wrist, were reviewed...

PURPOSE: Shortening osteotomy of the proximal radius might represent a potential salvage procedure in symptomatic radiocapitellar osteoarthritis, which could decrease radiocapitellar load while preserving the native radial head. In an in-vitro biomechanical investigation, we sought to determine whether shortening osteotomy of the proximal radius (1) decreases the radiocapitellar joint pressure upon axial loading and (2) retains valgus stability of the elbow. In addition, the anatomic configuration of the lesser sigmoid notch was evaluated to assess possible contraindications...

BACKGROUND: Subluxation of ulna in distal radioulnar joint disorders causes pain on motion, loss of grip strength, and a restriction of forearm rotation. Several procedures have been described to salvage DRUJ disorders including the Darrach procedure, the matched distal ulnar resection, the hemiresection interposition arthroplasty (Bowers procedure) and the Sauve-Kapandji (S-K) procedure. All these procedures are associated with either loss of grip, pain over proximal ulnar stump or instability...

PURPOSE: We evaluate the clinical and functional outcome of open primary repair of acute TFCC tears in distal radius fracture, when there is gross intraoperative distal radioulnar joint (DRUJ) instability after fixation of the distal radius, in the absence of an ulnar styloid fracture or when the ulnar fracture fragment is too small to be fixed. METHODS: A retrospective review of our institution's distal radius fracture database over a 4-year period (January 2010 to December 2013)...

Proper functioning of the hand relies on its capacity to rotate and point the palm upward (i.e. supination) or downward (i.e. pronation) when standing up with the elbow in 90° flexion. Hand rotation is possible because of forearm rotation and also rotation of the whole upper limb at the shoulder. Two distinct mechanisms contribute to hand rotation: one in which the ulna is immobile and another in which the ulna is mobile. In this review, we first summarize how evolution of the human species has led to the progressive development of specific forearm anatomy that allows for pronation and supination...

BACKGROUND: Some cadaveric studies have reported the role of the distal oblique bundle (DOB) in the distal radioulnar joint stability. We aimed to determine whether the presence of the DOB can be identified and its thickness can be measured in magnetic resonance imaging (MRI) examinations. METHODS: We retrospectively reviewed 468 wrist and forearm MRIs. Inclusion criteria were wrist or forearm MRIs taken in patients older than 18 years of age, and exclusion criteria were patients with acute wrist or forearm fractures, infections, or malignant tumors...

Background Complete dislocation of the distal radioulnar joint (DRUJ) is a rare injury. Dislocation can present as uni- or multidirectional, acute or chronic, reducible or irreducible. It can occur due to isolated loss of ligamentous restraints or more frequent in Galeazzi - or Essex-Lopresti-type fractures. Case Description A 28-year-old man sustained a distal radius fracture and presented after conservative treatment with blocked supination. Examination revealed a malunion of the distal radius in combination with an irreducible dorsal dislocation of the DRUJ...
