Brain activation due to postoperative pain from the right hand measured with regional cerebral blood flow using positron emission tomography.

Background Brain activation resulting from acute postoperative pain has to our knowledge not previously been studied using positron emission tomography, except from one case study. The aim of this study was to monitor activation in brain sensory pathways during acute pain after surgery of the hand. A secondary aim was to compare brain activation in clinical postoperative pain to that previously reported, by the same research group, for a model of experimental pain from the same body area.

Resurfacing the distal radioulnar joint with rib perichondrium-a novel method.

Background Osteoarthritis in the distal radioulnar joint (DRUJ) is a challenging condition with few really reliable surgical options, particularly in young individuals. Traditional methods as hemiresection, the Darrach procedure, and the Sauvé-Kapandji procedure have less favorable results in the nonrheumatoid patient. The results after implant arthroplasty have improved, but long-term results are yet to be presented before implant arthroplasty can be recommended to young individuals with osteoarthritis in the DRUJ.

Ectopic bone formation after medial femoral condyle graft to scaphoid nonunion.

Free vascularized bone graft from the medial femoral condyle has been described as a superior method for treatment of recalcitrant scaphoid nonunion with proximal pole avascularity and humpback deformity. Few complications and high union rates have been reported. In a series of three patients we describe an undesired volar ossification as a potential complication of the method.

Multiple brown tumours of the upper extremity in a patient with secondary hyperparathyroidism as a result of chronic renal failure.

A man with chronic renal failure was referred to the hand clinic because of massive osteolytic tumours in his right arm. Secondary hyperparathyroidism and brown tumours were suggested, and he was treated by subtotal parathyroidectomy. Rapid reduction of the vast tumours was noted postoperatively.

Nonoperative compared with operative treatment of acute scaphoid fractures. A randomized clinical trial.

Background: Traditionally, acute nondisplaced scaphoid fractures have been treated nonoperatively in a cast, and the expected union rate approaches 90%. Internal fixation of nondisplaced scaphoid fractures has increased in popularity, and a union rate of 100% has been reported. The growing trend is to recommend internal fixation for the majority of acute scaphoid fractures.

Comparison of direct and indirect costs of internal fixation and cast treatment in acute scaphoid fractures: a randomized trial involving 52 patients.

Background: The most cost-effective treatment of scaphoid fractures has not yet been determined.

Methods: In a prospective trial, 52 employed or selfemployed patients with scaphoid fractures were randomized to closed (cast) or surgical treatment.

Results: There were 3 complications in the surgical group and 1 in the cast group.

Patient-rating of long term results of silicone implant arthroplasty of the scaphoid.

Thirty-two patients had silicone implant arthroplasty of the scaphoid in our unit between 1974-1988. Ten years later eight had had their implants removed because they had failed. Twenty-four of the 32 were reviewed at an intermediate clinical follow up examination between 1988-89 and 21 by patient rated wrist evaluation 10 years later.
