Injuries and diseases of the hand naturally have an enormous impact on hand function and on quality of life, both occupational and social. The majority of hand-injury patients are under 30 years of age. Hand surgery, an established specialty in Sweden since 1969, is of great importance in terms of clinical developments, education and research. In the coming decade, scientific and clinical advances are to be expected in several fields such as nerve injuries including brachial plexus lesion, microsurgery, flexor tendon injuries and tendon transfer. Bioimplant research and new advances at the biotechnological interface will yield new options in nerve reconstruction, microchip implants in the nervous system, and the restoration of muscle-tendon function following injury. Artificial limbs with advanced motor and sensory functions will be important future aids in the rehabilitation of amputees. Transplantation of human hands is another promising reconstructive procedure which may open iup new perspectives in the coming millennium.
Recently, international guidelines for the diagnosis and management of diabetic polyneuropathy were issued. The aim of this initiative was to develop simple and practical guidelines for general practitioners and hospital physicians in day-to-day practice. Regular assessment of peripheral nerve function can be performed in diabetic patients using simple diagnostic tools. In such a way, patients will become more aware of the risks associated with diabetic neuropathy. Early detection of neuropathy and other risk factors for the development of foot ulcers may lead to avoidance of amputations. The guidelines emphasize foot care education of diabetic patients with or without neuropathy and early referral of patients with ulcerations to specialised outpatient foot clinic.
A MAJOR PROBLEM: Two-thirds of all amputations involve infection. Infection is favored by dysfunction of the antibacterial defense systems due to high blood glucose and vascular disorders. DIAGNOSIS: General signs of infection are usually not found. A careful exploration is required to rule out or confirm osteitis in order to guide surgery and plan the antibiotic regimen. A history of chronic and/or recurrent ulceration or direct signs at inspection may be suggestive of osteitis. Radiographic signs are late and nonspecific. Scintigraphy scans are difficult to interpret. Magnetic resonance imaging can be quite helpful in difficult cases. BACTERIOLOGICAL PROOF: Staphylococcus aureus and to a lesser extent streptococci account for almost all of the superficial infections in the diabetic foot. In case of deep ulceration, it is important to obtain deep specimens at surgical cleansing as more superficial samples are easily contaminated. Nevertheless, if Staphylococcus aureus is isolated from pus coming from a deep zone fistulizing to the skin, it is likely the causal agent since 80% of all bone infections involve S. aureus. Other germs besides staphylococci and streptococci include enterobacteria (40%), enterococci (26%) and pseudomonas (7%). Several germs are involved in about 70% of cases with a probable synergetic effect between the different bacterial colonies within the infected tissues.
