The Essex-Lopresti injury is an extremely rare condition combining radial head or neck fracture, distal radio-ulnar joint dislocation and rupture of the interosseous membrane. However, there are rare or unusual varieties or associated injuries. We report a case of a 46-year-old woman with a posterior dislocation of the radio-humeral joint, a radial shaft fracture, and a distal radio-ulnar joint dislocation. She underwent open reduction and internal fixation of the radial shaft fracture followed by an immobilization by a long elbow splint in supination for 6 weeks...

The aim of this meta-analysis was to compare the functional outcomes of patients with a distal radius fracture with and without a concomitant fracture of the ulnar styloid process. A systematic literature search was performed to identify all studies comparing patients with a distal radius fracture with and without an ulnar styloid process fracture. The initial search revealed 511 articles, of which 12 articles with a total of 2243 patients were included; 1196 patients with and 1047 patients without an ulnar styloid process fracture...

A study was undertaken to examine the presence of the distal oblique bundle of the forearm in a large sample in order to describe its true prevalence. The study sample consisted of 200 cadaveric forearms. Fifteen were excluded due to defects in the distal interosseous membrane. In the remaining 185 specimens, the distal interosseous membrane was examined following removal of soft tissue, to determine whether a distal oblique bundle was present and whether there were connecting fibres to the distal radio-ulnar joint...

Distal ulna fractures often occur with distal radius fractures, and their treatment method is still controversial. We considered reduction of the distal radio-ulnar joint (DRUJ) surface the most important factor when treating distal ulna fractures accompanied by residual dislocation. We herein presented a patient with a distal ulna fracture accompanied by dislocation of the DRUJ surface in whom an autogenous bone fragment collected from the radius was grafted onto the ulnar bone defect after open reduction and Herbert screw fixation...

INTRODUCTION: Fracture of the distal end of radius represents the most common fracture of the upper extremity accounting for 16-20% of all fractures. Plating is now emerging as the gold standard for management of distal radius fractures due to increased rate of complications such as malunion, subluxation/dislocation of distal radio-ulnar joint or late collapse of fracture. Procedures such as closed reduction and cast immobilization, ligamentotaxis with external fixator and percutaneous pin fixation are no longer acceptable...

The use of implant arthroplasty in the hand and wrist is increasing, often with little evidence of outcomes in the literature. We therefore undertook a systematic review of the outcomes of distal radio-ulnar joint arthroplasties following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Papers were assessed for outcomes, implant survival and methodological quality. Fourteen papers assessed ulna head replacements. The implant survival rate was 93% at a mean follow-up of 45 months...

We report our 11-year experience of performing arthroscopically assisted triangular fibrocartilage complex reconstruction in the treatment of chronic distal radio-ulnar joint instability resulting from irreparable triangular fibrocartilage complex injuries. Eleven patients were treated. Three skin incisions were made in order to create radial and ulna tunnels for passage of the tendon graft, which is used to reconstruct the dorsal and palmar radio-ulnar ligaments, under fluoroscopic and arthroscopic guidance...

INTRODUCTION: We report a case of Type 1 Monteggia equivalent injury with intact radio-capitellar congruity, associated with epiphyseal fracture of distal radius and distal ulna shaft in an 11-year-old boy. There are only a few cases of Monteggia or Monteggia equivalent injury with ipsilateral forearm fractures in children, and injury pattern being reported by us is not only rare but also the only case reported thus far to the best of our knowledge, Sood et al. described Type 1 equivalent with epiphyseal injuries of both radius and ulna Osada et al...

The classical definition of 'Palmer Type IB' triangular fibrocartilage complex tear, includes a spectrum of clinical conditions. This review highlights the clinical and arthroscopic criteria that enable us to categorize five classes on a treatment-oriented classification system of triangular fibrocartilage complex peripheral tears. Class 1 lesions represent isolated tears of the distal triangular fibrocartilage complex without distal radio-ulnar joint instability and are amenable to arthroscopic suture. Class 2 tears include rupture of both the distal triangular fibrocartilage complex and proximal attachments of the triangular fibrocartilage complex to the fovea...

This study evaluated the value of computed tomography scans for the diagnosis of distal radioulnar joint instability. A total of 46 patients, conservatively treated for a unilateral distal radius fracture, were evaluated. Clinical instability was tested using the stress test and clunk test. A computed tomography scan of both wrists was performed in pronation and supination. Two independent observers reviewed the computed tomography scans using: the radioulnar line, subluxation ratio, epicentre and radioulnar ratio methods...

We examined the medium- to long-term outcome of the original reconstruction technique of the radioulnar ligament using a half-slip of the extensor carpi ulnaris tendon for chronic foveal avulsion of the triangular fibrocartilage complex. We treated 37 wrists in 36 patients with a minimum follow-up of 5 years. Of 36 patients, 12 had more than 10 years follow-up. At final follow-up, 30 patients (31 wrists) reported no pain, five patients (five wrists) reported mild occasional pain and one patient reported severe persistent pain...

Distal radius fracture is actually quite rarely isolated and triangular fibrocartilaginous complex (TFCC) is often involved with the same mechanism of injury. A contemporary management of the treatment of the initial fracture is ideal and so benefits from a routine arthroscopic management. Nevertheless, in the absence of diagnosis and therefore early treatment, the symptoms may be located at the ulnar crossroads and justify specific treatment of TFCC. It is generally conducted after an accurate arthroscopic lesion classification guiding a procedure, depending on the lesion vascularization as well as its possible destabilization potential (debridement, capsular suture or foveal reattachment)...

Extensive anatomical knowledge is needed in order to correctly treat distal radius fractures: normal and pathological osteology of the distal radius, distal radio-ulnar joint and radiocarpal joint-both on the descriptive and functional level-the neurovascular and muscular environments of the distal radius-which are essential to the surgical approaches-and the angles that need to be restored during the reduction. All of these concepts are broached in this article.

The objective of this study was to determine the precise departure points of the articular branches innervating the distal radio-ulnar joint from the anterior and posterior interosseous nerves. The study sample consisted of 116 upper limbs from adult human cadavers. The articular branches were prepared under the dissection microscope to take measurements using the radial styloid process as point of reference. The articular branch departed from the anterior interosseous nerve at a mean distance of 2.9 cm proximal to the styloid for a radius length of 20...

REVIEW
J Phadnis, A C Watts
The Essex Lopresti lesion is a rare triad of injury to the radial head, interosseous membrane of the forearm and distal radio-ulnar joint, which results in longitudinal instability of the radius. If unrecognized this leads to chronic pain and disability which is difficult to salvage. Early recognition and appropriate treatment is therefore desirable to prevent long-term problems. The aim of this article is to review the pathoanatomy of longitudinal radius instability and use the existing literature and authors' experience to provide recommendations for recognition and treatment of acute and chronic forearm instability, including description of the author's technique for interosseous membrane reconstruction...

OBJECTIVE: The goal of this operation technique is a stable refixation of the triangular fibrocartilage complex (TFCC) to the fovea ulnaris. The stability of the distal radio-ulnar joint (DRUJ) should be re-established. The patients pain and the feeling of instability should be reduced. INDICATIONS: Lesions of the foveal component of the TFCC resulting in DRUJ instability. Combined lesions of both components of the TFCC. Complete detachment of the TFCC from the ulna either without fracture of the styloid process of the ulna or with fracture (floating styloid)...

The main function of the forearm is the supination, which is achieved largely through the biomechanical characteristics and stability of the distal radio-ulnar joint. There are several surgical techniques for the treatment of distal radio-ulnar dislocations isolated or associated with a fracture. We report the case of a canine trainer who was bitten at the wrist and distal forearm that came to the emergency department in where distal ulnar dislocation with muscle tendon exposure was diagnosed. Due to the offending agent and multiple soft tissue injuries the treatment with standard techniques was impossible...
