Scientific titleThe treatment of fresh scaphoid fractures with Pulsed Electromagnetic Fields (PEMF)
Study objectivesThe addition of PEMF to cast immobilisation in fresh scaphoid fractures will accelerate consolidation both clinically and radiologically. Possibly the incidence of non-union will be reduced.
Ethics approval(s)Ethics approval received from the local medical ethics committee
Health condition(s) or problem(s) studiedScaphoid fractures
InterventionAll patients suspected of having a fresh scaphoid fracture will be treated with cast immobilisation. Scaphoid fracture is diagnosed by a combination of physical and radiographic examination. If no apparent fracture line is seen on the initial X-rays, a Technetium scan will be performed (3 - 6 days after injury) to confirm the diagnosis. The PEMF device (supplied by commercial support) will be placed on the cast within one week and will be applied for 24 hours a day continuously. The cast will be a lower arm cast with the first metacarpal bone immobilised. Since the position of the thumb and the hand have no adverse effect on the displacement of the fracture or it’s consolidation, this neutral plaster is choosen.

Half of the PEMF devices will be disabled at random in the factory. These disabled devices will give outward signs of normal function but will not generate a signal. The investigators will be unaware of the device’s functionality. At study completion, device serial numbers will be used to determine which patients received a working device.

Follow up will take place at four, six, twelve and twenty-four weeks after diagnosis of the fractured scaphoid. When the fracture has both clinically and radiologically consolidated the plaster will be removed. If the fracture has not consolidated; a new plaster will be made. Only patients who need immobilisation of the fracture (not consolidated fractures) will have a PEMF device on them, for in clinically and radiographically consolidated patients there is no need for further treatment. If consolidation was established before, it can be checked at later follow up dates if that conclusion wasn’t premature. If the fracture is not consolidated after twelve weeks, at physical or radiographic examination, yet the patient has no pain the treatment is finished. If the patient has got pain, he will get a removable splint. All tests will be compared with the opposite unaffected side. In addition to the physical and radiographic examination, patients will be required to fill in two questionnaires:
1. 36-item Short Form health survey (SF-36)
2. The McGill Pain Questionnaire (multidimensional description of the patient’s feelings of pain)
Intervention typeOther
Primary outcome measureConsolidation of the fracture; at 4, 6, 12 and 24 weeks after inclusion the patients will be examined (both radiologically and physically) and will be asked to fill in the questionnaires.
Secondary outcome measuresNo secondary outcome measures
