The use of pulsed electromagnetic fields (PEMF)
to stimulate bone growth has been recommended as an alternative to
the surgical treatment of ununited scaphoid fractures, but has never
been examined in acute fractures. We hypothesised that the use of
PEMF in acute scaphoid fractures would accelerate the time to union
by 30% in a randomised, double-blind, placebo-controlled, multicentre
trial. A total of 53 patients in three different medical centres
with a unilateral undisplaced acute scaphoid fracture were randomly
assigned to receive either treatment with PEMF (n = 24) or a placebo
(n = 29). The clinical and radiological outcomes were assessed at
four, six, nine, 12, 24 and 52 weeks. A log-rank analysis showed that neither time to clinical and
radiological union nor the functional outcome differed significantly
between the groups. The clinical assessment of union indicated that
at six weeks tenderness in the anatomic snuffbox (p = 0.03) as well
as tenderness on longitudinal compression of the scaphoid (p = 0.008) differed
significantly in favour of the placebo group. We conclude that stimulation of bone growth by PEMF has no additional
value in the conservative treatment of acute scaphoid fractures.
The aim of this study was to evaluate the radiological outcome of patients with large bone defects in the femur and tibia who were treated according to the guidelines of the diamond concept in our department (Centre for Orthopedics, Trauma Surgery, and Paraplegiology). The following retrospective, descriptive analysis consists of patients treated in our department between January 2010 and December 2021. In total, 628 patients were registered, of whom 108 presented with a large-sized defect (≥ 5 cm). A total of 70 patients met the inclusion criteria. The primary endpoint was radiological consolidation of nonunions after one and two years via a modified Lane-Sandhu Score, including only radiological parameters.Aims
