15-20 Year Follow-up After Wrist Arthroplasty Surgery - Revisiting the Development and Introduction of a New Prototype Concept for Total Wrist Arthroplasty.

Wrist arthroplasties have not achieved clinical outcomes comparable to those of shoulders and knees, being offered low-demand patients due to a high failure rate. In the 90s, there were no wrist arthroplasties available for high-demand patients. An experimental setup for the development of a new wrist arthroplasty intended for all wrist patients were done.

Progressing arthrosis and a high conversion rate 11 (4-19) years after four corner fusion.

Four corner fusion (4CF) is a limited wrist arthrodesis offered to patients with painful wrists due to scaphoid non-union advanced collapse (SNAC) or scapho-lunate advanced collapse (SLAC). A retrospective study of 42 wrists (in 36 patients), operated with 4CF using K-wires and autologous bone graft followed up after 11 (4-19) years was performed, 25 were male and mean age at surgery was 51 (22-71) years. During the follow-up period, 13 wrists were converted to total wrist arthrodesis or wrist arthroplasty, and one is scheduled for conversion (14/42, 33%) due to non-union (3), DISI and progressing arthrosis (7) or progressing arthrosis (4).

Satisfactory function 12 years after triscaphoid arthrodesis for chronic scapholunate ligament injury.

Scapholunate ligament (SLL) injury represents a hazard to the wrist and the treatment of these injuries has been the focus of much debate. We performed a long-term follow (>10 years) of triscaphoid arthrodesis for symptomatic chronic SLL injuries in 10 (8 men) patients 37 (22-49) years of age. All arthrodesis healed.

Five- to 10-Year Prospective Follow-Up of Wrist Arthroplasty in 56 Nonrheumatoid Patients.

Purpose: The goal of the study was to evaluate the clinical and radiological outcomes of a cementless wrist arthroplasty with minimum 5-year follow-up in nonrheumatoid patients.

Methods: Fifty-seven (40 male) patients with end-stage arthritis changes received an uncemented ball-and-socket total wrist arthroplasty (Motec Wrist). Function was evaluated before surgery and at yearly follow-ups.

Examination and treatment of scaphoid fractures and pseudarthrosis.

Background: About 2,000 patients annually incur a fractured scaphoid in Norway. Assessment and diagnosis can be difficult, and fractures are overlooked. Scaphoid fractures have traditionally been cast-immobilised, but for the last decade screw fixing has been used increasingly, and offers hope of a higher healing frequency and improved function.

Scaphoid non-unions, where do they come from? The epidemiology and initial presentation of 270 scaphoid non-unions.

Scaphoid injury and subsequent non-union is a well documented and researched subject. This article gives an overview of the epidemiology and results of the patients we have treated for scaphoid non-union at a University Hospital. 283 scaphoid non-unions in 268 patients (83% men) were operated upon, 230 as a primary and 47 as a secondary.

Excellent results after bone grafting and K-wire fixation for scaphoid nonunion surgery in skeletally immature patients: a midterm follow-up study of 11 adolescents after 6.9 years.

Objectives: Scaphoid nonunion is relatively rare in children and adolescents, and no long-term follow-up has been reported.

Design: Retrospective follow-up study.

Patients: Eleven patients (10 boys and 1 girl), mean 15.

Long-term results of scaphoid nonunion surgery: 50 patients reviewed after 8 to 18 years.

Objectives: Untreated scaphoid nonunions are a hazard to the wrist, resulting in deteriorating function and radiologic degenerative changes with increasing time. Long-term results after surgery of scaphoid nonunion reporting clinical, radiologic, and subjective outcomes are scarce.

Design: Retrospective follow-up study.

New concept for total wrist replacement.

Wrist prostheses have never achieved the sort of clinical outcomes found with those of hips and knees. We have developed a novel uncemented modular wrist prosthesis with screw fixation, metal-on-metal coupling, and ball-and-socket articulation. Eight patients admitted for wrist arthrodesis to treat primary or secondary osteoarthritis (not rheumatoid) were operated on.

Supracondylar fractures with circulatory failure after reduction, pinning, and entrapment of the brachial artery: excellent results more than 1 year after open exploration and revascularization.

Objectives: Neurovascular injuries in children with dislocated supracondylar humeral fractures are not uncommon. Closed reduction and pin fixation usually will restore the circulation. In some patients, there is still compromised circulation and a neurologic deficit, and they are treated with open exploration and microvascular reconstruction.

Healing of ununited scaphoid fractures by Kirschner wires and autologous structural bone grafts.

Untreated ununited scaphoid fractures are a hazard to the wrist because of increasing degenerative changes with time. We have treated 81 consecutive ununited scaphoid fractures by open reposition, autologous bone transplantation, and Kirschner wire fixation, 2.7 years after the primary injury.

Complications in knee arthroscopy.

All simple arthroscopic procedures during 1999 through 2001 performed at Baerum community hospital were retrospectively examined. Procedures were excluded when being part of more complex procedures. A total of 876 procedures performed on 785 patients were left for examination.
