Over a two-year period, 265 Norwegian orthopaedic surgeons working at 71 institutions performed 63,484 operations under a tourniquet. Their replies to a questionnaire revealed that they mostly followed modern guidelines in their use of the tourniquet. Most felt that the tourniquet could be left on for two hours, and that it could be re-applied after 15 minutes. A total of 26 complications (one in 2442 operations) that might have been due to the tourniquet were reported, of which 15 were neurological. Three were in the upper limb (one in 6155 operations) and 12 in the lower limb (one in 3752 operations). Two were permanent (one in 31,742 operations), but the remainder resolved within six months. One permanent and one transient complication occurred after tourniquet times of three hours. The incidence of tourniquet complications is still at least as high as that estimated in the 1970s.

BackgroundBone mineral density (BMD) has been shown to be a consistent and independent risk factor for distal radius fracture. Inconsistent data have been reported on the association between BMD and severity of distal radius fracture. Our primary aim was to explore if there is an association between cortical BMD at the hand and the severity of fragility distal radius fracture.MethodsConsecutively recruited females aged ≥50 years with fragility fracture at the distal radius (n = 110) from a county hospital were included. Cortical hand BMD was assessed by the digital X-ray radiogrammetry (DXR) method. X-rays of the fracture were scored by experienced orthopedic surgeons for fracture severity according to the Müller AO classification of long bones and radiographic parameters such as ulnar variance and dorsal angle.ResultsA weak association between lower DXR BMD and increased ulnar variance and dorsal angle was found but not with the AO scoring system for fracture type. A history of glucocorticoid (GC) use but not DXR-BMD was found to be significantly associated with the presence of having an intra- or extra-articular fracture.ConclusionOur data indicate that bone material properties which are impaired by GC use are more important for fracture severity than BMD.
