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...

The Sauvé-Kapandji procedure is a reliable option for patients with various disorders of the distal radioulnar joint (DRUJ). However, postoperative pain over the proximal ulnar stump frequently develops during forearm rotation or when lifting heavy objects, although many clinically satisfactory results have been reported. This stump pain has been suggested to result from dynamic instability of the proximal ulnar stump. Several types of tenodesis have recently been performed simultaneously with the Sauvé-Kapandji procedure to stabilize the proximal ulnar stump and thus relieve the associated pain...

We investigated the relationship between the radial inclination of the distal radius and distal radioulnar joint stability. Six fresh-frozen upper extremities were used. Radial inclination was decreased by 10° and 20° and increased by 10° from the original radial inclination. Distal radioulnar joint stiffness was assessed with an intact radioulnar ligament and after partial and then complete sectioning of the radioulnar ligament. Radial angulation deformities significantly increased distal radioulnar joint stiffness when the radioulnar ligament is totally or partially attached to the ulnar fovea...

A 40-year-old woman presented with Madelung deformity and severe arthritic changes at both the radiocarpal and the distal radioulnar joints. She was treated by using her lunate as an osteochondral graft into the radius allowing reconstruction of the lunate fossa. The scaphoid and triquetrum were removed concomitantly and a Sauve-Kapandji procedure was performed. Complete bone healing was achieved. Ten years later, an excellent functional result was maintained, with a pain-free wrist, an acceptable wrist joint range of motion, as well as a favorable aesthetic appearance...

We assessed whether radial shaft fracture obliquity measurements on radiographs could predict intra-operative distal radioulnar joint instability. We also clinically validated previously described predictors of distal radioulnar joint instability, which included a fracture line within 7.5 cm of the lunate fossa, radial shortening >5 mm, and ulna styloid fracture. We retrospectively analysed the radiographs of all surgically managed patients in our unit with radial shaft fractures from 2006 through 2016...

Radial shaft convergence in distal radius fractures is often misdiagnosed. This common deformation is often associated with a radial translation of the distal fragment. This parameter has to be corrected because of the increased risk of distal radioulnar joint instability due to detensioning of the distal interosseous membrane if there is an associated triangular fibrocartilage complex lesion. A new radiologic sign for diagnosis of proximal radius convergence during distal radius fracture is presented as well as technical tips for correction of this deformity...

Distal ulnar fractures often occur with distal radius fractures (DRFs), and ulnar styloid fractures commonly occur in the setting of DRF. However, isolated ulnar head fractures are rare. We report a case of isolated ulnar head fracture in which we performed bone resection because the ulnar head bone fragment fractured when internal screw fixation was attempted. His outcome at 18 months postoperatively was considered excellent. However, we do not advocate bone resection other than failure of fixation and the difficult case to perform internal fixation...
