Comparative Study
[A-mode ultrasonic pointer for navigated pelvic surgery].
Surgical navigation has proven to be a minimally invasive procedure that enables precise surgical interventions with reduced exposure to irradiation for patient and personnel. Fluoroscopy-based modules have prevailed on the market. For certain operations of the pelvis computed tomography is necessary with its high imaging quality and considerably larger scan volume. ⋯ This conflicts with the claim of computer-assisted surgery to be minimally invasive. We integrated an A-mode ultrasonic pointer with the intention to perform extended surface matching on the pelvic bone noninvasively. Related to the conventional method, comparable and to some extent even improved precision conditions could be established.

The formation of a scaphoid pseudarthrosis with avascular necrosis in the area of the carpus is a The formation of a scaphoid pseudarthrosis with avascular necrosis in the area of the carpus is a dreaded complication after conservative or operative treatment of a scaphoid bone fracture, which previously often led to partial or total stiffening operations on the wrist. Vascularized bone grafts can be used to increase the bone fusion rates in the presence of scaphoid pseudarthrosis with avascular necrosis. ⋯ We transplanted a free vascularized cartilage-bone graft from the medial femoral condyle, which was adapted in form and size to the proximal scaphoid bone pole with corresponding cartilage cover and was connected to the radial vascular bundle. This novel operation technique is described in this report and appears to be a promising way of avoiding premature radiocarpal arthritis when treating scaphoid bone pseudo-arthrosis with avascular necrosis in the presence of cartilage destruction.

After a fracture of the distal radius, whether healed in an anatomic position or malunited, many patients complain about problems on the ulnar side of the wrist with pain and decreased range of forearm rotation. In addition many patients are unhappy with the unpleasant appearance of the wrist joint. ⋯ Malunion of the distal radius must be taken into account when discussing treatment options. The purpose of this paper is to describe a treatment algorithm with respect to the clinical symptoms, the pathology as well as the presence or absence of a deformity of the distal radius.

Modern communication and information technologies are ubiquitous nowadays, and the medical field is no exception. Telemedicine is a reasonable way to prevent accidents, communicate faster in an emergency, and improve medical care in the hospital. ⋯ This article highlights these subjects and discusses national and international structures that promote the spread of health telematics. Barriers to this path are also shown.
