Denervation of the wrist in patients with SLAC-/SNAC-wrist stages II and III can achieve a long-term elimination or reduction of pain, whilst improving hand strength, and having only a minimal impact on wrist range of movement. Wrist denervation should therefore be given preference over wrist arthrodesis, midcarpal arthrodesis or proximal row carpectomy in patients with good wrist mobility.
A stable and optimal reduction and a rigid internal osteosynthesis are requisites for healing of the radius fracture. Open reduction of the DRUJ is only indicated when soft tissue interposition prevents exact reposition. Surgical revision of the distal radioulnar joint was not necessary in our patients. Patients after Kirschner-wire fixation showed a diminished pro- or supination. To prevent Kirschner-wire failure, postoperative cast immobilization is indicated. Due to the retrospective nature of the study it is not definitely clear if Kirschner wire fixation is superior to immobilization.
Animal bites make up a large proportion of the injuries treated in an emergency department. Due to the type of injury, the variety of wounds and the contamination with aerobic and anaerobic organisms, they deserve special attention. In this study, we reviewed 98 patients (55 male/43 female) with bite wounds to the hand and wrist treated between 1995 and 2000. They were either treated conservatively (n = 65) or surgically (n = 33) depending on the clinical findings. In 18 of 33 cases, the reason for surgical treatment was an infection. A primary antibiotic prophylaxis, usually with cephalosporines, was administered in 47 of 98 cases. Results were analysed retrospectively. An infection developed in 32 patients. In six of these patients, an infection developed despite primary antibiotic prophylaxis. Operative treatment became necessary in four of these six cases. Twenty-six of 32 patients were treated without primary antibiotic prophylaxis. Surgical treatment was required in around half (n = 14) of these patients, while the other 12 patients were treated conservatively with antibiotic therapy.Twenty-one of 26 patients presented with bite wounds that were already infected. Microbiological examination revealed a variety of microbes, usually a mixed infection with Pasteurella multocida was found. All organisms were susceptible to treatment with second or third generation cephalosporines.A total of 15 patients had to be operated due to deeper injuries to the bone, extensive soft-tissue injury, or because of injury to a tendon and the tendon sheath. In most patients, a good to acceptable functional result was achieved. Primary antibiotic prophylaxis does not prevent the development of infection. Nevertheless, because of the inherently high infection risk associated with bite wounds to the hand and wrist, prophylaxis should be carried out. In case of severe damage to the soft tissue or signs of infection, early surgical therapy should be considered.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
