    Description / Table of Contents: Abstract Introduction: The loss of functional capacity by peripheral nerve lesion is easy to be estimated: A certain neurologic dysfunction results in a characteristic reduction of the former individual capacity. In contrast, the effect of accompanying pain to every-day life and working ability is not known exactly. In this study, we compared the results of judgement in nerve lesions under the circumstances of additional pain syndromes. Methods: From January 1994 until Dezember 1998 we saw 57 patients with peripheral nerve lesions, part of them with an additional pain syndrome. Beside conventional neurological examination a detailed pain analysis has been done. Results: Lesions of the median or ulnar nerves showed regularly disturbences in neurological functions (10/14 for the mediane nerve, 13/16 for the ulnar nerve). Astonishing is the fact, that serious pain after nerve lesion only occurs in cases of partial nerve lesion. We saw neuralgias in 6 patients with ulnar neuropathy, in three cases of median nerve lesions we could see severe neuralgia (causalgia we found in 3 cases of ulnar neuropathy, in 6 cases after Median Nerve lesion). Patients with a lesion of the central plexus brachialis showed in 10 of 11 cases an additional pain syndrome. Other nerves have been affected more rarely. For the judgement of the loss of earning capacity we saw an additional pain related diminuition of at least 10% compared to those patients without pain problems. Conclusions: The common grading scales for peripheral nerve lesions are not suitable in cases accompanied by an additional pain syndrome. Beside a functional deficit the effect of severe pain in these patients has to be estimated. On an average, patients with addtitional pain-problems get a 10% extended loss of earning capacity, even more in particular cases.
    Notes: Zusammenfassung Fragestellung: Anhand retrospektiver Daten sollten geeignete Bewertungsgrundlagen für die Begutachtung peripherer Nervenläsionen erarbeitet werden. Methode: Von Januar 1994 bis Dezember 1998 wurden insgesamt 57 Patienten (36 männlich, 21 weiblich, Durchschnittsalter 33,9 Jahre) mit dieser Fragestellung im Rahmen einer Begutachtung untersucht. Ursächlich lagen traumatische Ereignisse bei 39 (68%), postoperative Störungen bei 14 und andere Schädigungen bei 4 Patienten zugrunde. Ergebnisse: Beim N. medianus und N. ulnaris (beispielhaft) überwogen die Schmerzzustände bei inkompletten Läsionen. Neuralgien fanden sich bei 3 bzw. 6 Patienten mit N.-medianus- bzw. N.-ulnaris-Läsion. Eine Kausalgie fand sich bei 6 bzw. 3 Patienten. Mit Ausnahme von Armplexusläsionen waren andere Nerven seltener betroffen. Diese Situation wurde mit einer durchschnittlich um 10% höher gelegenen Einschätzung der Leistungseinbuße berücksichtigt, wenn gleichzeitig Schmerzen vorlagen. Schlussfolgerungen: Die für die reine Funktionseinbuße gültigen Skalen zur Bemessung peripherer Nervenläsionen können für die Begutachtung von Schmerzsyndromen nur bedingt herangezogen werden. Meist führen Schmerzen zu einer um durchschnittlich 10% höheren Einschränkung der Erwerbsfähigkeit (MdE), allerdings sind in manchen Fällen auch größere Einbußen denkbar.

    Notes: Abstract We report on two cases of compartment syndrome following lumbar discectomy in the knee-chest position. This complication has only been described once since 1953. Seven cases of compartment syndrome following other surgical procedures were found in the literature. Any increases in tissue pressure of a muscle compartment exceeding 35–40 mmHg over a longer period of time can result in this complication for example, too tight cast, space-occupying intrafascial bleeding, or postischemic swelling. The diagnosis is purely clinical and is based on the typical combination of extremely painful edema with rapid onset of sensory loss and subsequent motor deficits. The muscle necrosis leads to myoglobinaemia and myoglobinuria, recognizable by brown urine. The therapy consists of urgent fasciotomy of swollen compartements without skin suture. The prognosis is highly dependent on the time of the surgical decompression: within 6 hours serious deficits are avoidable; after 24 hours irreversible necrosis of muscle occurs. It seems that the possibility of a compartment syndrome is a specific, but a rare risk of a prolonged knee-chest position.
