Treatment of nonunited scaphoid fractures by pulsed electromagnetic field and cast.

چکیده
Thirty-five of 44 nonunited scaphoid fractures that were at least 6 months old healed in a mean time of 4.3 months during pulsed electromagnetic field (PEMF) treatment using external coils and a thumb spica cast. The mean time from the onset of the fracture to treatment was 40 months. No concurrent operation was performed. Follow-up time averaged 8.4 months. Eight of nine fractures with avascular necrosis healed. Five of eight fractures in the proximal third healed. Twelve (75%) of 16 patients treated in short-arm thumb spica casts and PEMF healed versus 22 (92%) of 24 patients treated initially in long-arm thumb spica casts and PEMF. We have found PEMF to be a reliable alternative method of treating nonunited scaphoid fractures. Because of the low risk, simplicity of use, and reliability, we recommend its consideration in the treatment of undisplaced, nonunited fractures without carpal instability less than 5 years after the injury. Treatment should initially begin with a long-arm cast.

Pulsed Electromagnetic Fields in the treatment of fresh scaphoid fractures. A multicenter, prospective, double blind, placebo controlled, randomized trial
BACKGROUND The scaphoid bone is the most commonly fractured of the carpal bones. In the Netherlands 90% of all carpal fractures is a fracture of the scaphoid bone. The scaphoid has an essential role in functionality of the wrist, acting as a pivot. Complications in healing can result in poor functional outcome. The scaphoid fracture is a troublesome fracture and failure of treatment can result ...

Nonunion of fractures or osteotomies in the pediatric population is rare. The gold standard for the treatment of nonunions involves harvesting autologous iliac crest bone graft and sometimes internal fixation, which are invasive procedures. The purpose of this study was to evaluate the effectiveness of pulsed electromagnetic field on a non-united fracture or osteotomy in the pediatric populatio...

BACKGROUND Physical forces have been widely used to stimulate bone growth in fracture repair. Addition of bone growth stimulation to the conservative treatment regime is more costly than standard health care. However, it might lead to cost-savings due to a reduction of the total amount of working days lost. This economic evaluation was performed to assess the cost-effectiveness of Pulsed Electr...

BACKGROUND The scaphoid fractures account for 50%-80% of all carpal bone fractures in young individuals. Non-union of the fracture occurs in approximately 5%-10% of undisplaced scaphoid fractures. Current management varies significantly among different places and surgeons. OBJECTIVES The purpose of this review is to investigate the evidence of the effectiveness and safety of various treatment...
متن کاملTreatment of acute scaphoid fractures: systematic review and meta-analysis.
Whether operative treatment is a better option than nonoperative treatment for acute nondisplaced or minimally displaced fractures of the scaphoid is controversial. The type of cast that should be used for nonoperative treatment is not known. We performed a systematic review and meta-analysis of randomized and quasirandomized trials to evaluate the effect of operative versus nonoperative treatm...
