[Scaphoid enchondroma revealed by a fracture].

Enchondroma is a common bone tumor of hand. It is rarely localized in scaphoid. We report a new case of this tumor revealed by fracture. The diagnosis was suggested by standard radiography and confirmed then by anatomic pathology examination. Enucleation and bone graft with osteosynthesis yielded good result.

Scaphoid nonunion with avascular necrosis of the proximal pole. Treatment with a vascularized bone graft from the dorsum of the distal radius.

Scaphoid nonunion with avascular necrosis of the proximal pole remains a difficult problem. We have endeavoured to heal the fracture, restore scaphoid height and revascularize the proximal pole of the scaphoid by means of a vascularized dorsal interposition graft from the distal radius. The procedure has resulted in union of six of ten fractures. Fractures that healed had not been treated by a previous bone grafting procedure. Dissatisfaction was due to loss of motion in patients who had healed fractures, and pain in those patients with persistent non-unions.

Demonstration of the scapholunate space with radiography.

The importance of radiographic evaluation of the scapholunate space, which should not be wider than 2 mm, has been well established in cases of wrist injury. Unfortunately, the assessment of this space is not accurately determined with routine posteroanterior (PA) radiographs, because the scaphoid and lunate bones often overlap. Moreover, the exact portion of the scapholunate space that should be measured has never been clearly defined. Nine wrists with a scapholunate space no wider than 2 mm and without chondrocalcinosis were studied by means of plain routine views and special projections, transaxial and coronal computed tomographic scans, and dissection to determine the precise orientation and anatomy of this space. A PA radiograph with 10 degrees of tube angulation from the ulna toward the radius best demonstrated the scapholunate space. This space should be measured at the level of the midportion of the flat lateral facet of the scaphoid.

[Osteosynthesis for scaphoid fractures through a dorsal approach: one or two Herbert screws?].

The aim of this work is to show the merits of retrograde scaphoid fixation through a dorsal approach using two Herbert screws in both recent and old fractures, without the need for bone grafting. Fifty three scaphoid fractures were operated on by the author between 1992 and 2000, using a dorsal approach (mean follow-up 4 years). The time between trauma and surgery, the type of fracture, the mode of bone fixation, the time of immobilisation, and the clinical and radiological results were all been evaluated. All fractures but one united, in a mean time of 75 days. The time needed to achieve bone union increases with the delay in treatment, as does the time for clinical healing which may be as long as one year. The technique of retrograde scaphoid fixation with two Herbert screws is described, evaluated from the biomechanical point of view, and compared to other methods of fixation. In contrast to a single screw, two Herbert screws give complete stability of fixation, and guarantee a good clinical result provided the correct indications have been selected. This technique has advantages as an alternative procedure, especially in fractures that present after a significant delay, and enables one to avoid having to bone graft.

Osteoid osteoma of the carpal bones.

Three cases of osteoid osteoma of the carpal bones are described, with a review of the literature. The scaphoid is the carpal bone involved most frequently. Typically the lesions are painful and respond to aspirin. Roentgenologic finding of the central area of lucency surrounded by sclerotic bone often is diagnostic. Block excision with bone grafting is an acceptable method of treatment.

[Use of the Herbert screw with the freehand method for osteosynthesis of acute scaphoid fracture].

Scaphoid fracture is, in most cases, usually still treated conservatively. The disadvantages of long-term immobilization are stiffness of the wrist joint, loss of strength and higher costs. The osteosynthesis of the scaphoid fracture with the Herbert bone screw restores the exact form and length and the normal position of the scaphoid to the other carpal bones. It prevents non-unions, arthrosis and other late complications. The Freehand method is used as a percutaneous technique without utilization of a jig. The scaphoid fracture is treated with closed reduction and osteosynthesis is performed with the Herbert bone screw. The percutaneous technique preserves the inter- and intracarpal ligaments, the vascular supply and the articular surfaces of the scaphoid. Osteosynthesis by the Freehand method is sufficiently stable to withstand early functional moves on the first postoperative day.

The effects of Scaphoid and Colles casts on hand function.

Although necessary for bone healing, immobilisation temporarily prevents hand function and may necessitate corrective physiotherapy later. Scaphoid and Colles casts are both commonly used to immobilize scaphoid fractures. Non-union rates are comparable with both casts. The Scaphoid cast incorporates the thumb, whereas the Colles cast leaves the thumb free. We compared the effect of the two casts on hand function in 20 healthy right-hand-dominant volunteers using the Jebsen-Taylor Hand Function Test. Data were obtained through a mixed between and within subject design. Both casts prolonged the time taken to complete the hand function test compared to controls. Testing in the Scaphoid cast took significantly longer than in the Colles cast.
