Verz?gerte Radialisparese nach Monteggia-Fraktur – Ein Fallbericht

Nervensch?digungen als Begleitverletzungen bei Monteggia-Frakturen sind selten und betreffen meistens den N. radialis. üblicherweise kommt es bei frischen Frakturen zu einer spontanen neurologischen Remission, nachdem der Radiuskopf wieder reponiert wurde. Im vorliegenden Fall erlitt ein heute 33-j?hriger Mann eine Parese des N. interosseus posterior 27 Jahre nach einer Monteggia-Fraktur, wobei der Radiuskopf in luxierter Stellung verblieb. Nach einem Bagatelltrauma am Handgelenk beim Federballspielen kam es zu einer L?hmung der Handgelenk- und Fingerstreckmuskulatur. Eine konservative Behandlung mittels intensiver Physiotherapie blieb auch nach 4 Monaten erfolglos. Daraufhin wurde der Nerv exploriert. Der Profundusast zeigte sich dabei narbig adh?rent im Bereich einer beengenden und verdickten Frohse-Arkade. Anschlie?end erfolgte eine Narbenl?sung sowie Spaltung der Arkade, der Radiuskopf wurde im ursprünglichen verrenkten Zustand belassen. Eine v?llige Erholung des l?dierten Nerven war 9 Monate postoperativ erreicht.     

Movement timing in deaf and hearing speakers: comparison of phonetically heterogeneous syllable strings

We review evidence suggesting that deaf speakers do not move their articulators toward the following open posture throughout closure and report results from a preliminary cinefluorographic study. Two prelingually deaf and two hearing speakers produced two different strings of alternating heterogeneous monosyllables as though speaking in time with a metronome (the so-called P-center task). Events traditionally associated with vowel production appeared evenly timed throughout the productions, and, in general, the deaf speakers performed similarly to the hearing speakers. We relate the results to Fowler's (1983) interpretation of the P-center phenomenon as an indicant of continuous vowel production.

Operative Versorgung von Achillessehnenverletzungen

Rupture of the Achilles tendon is typically associated with sportive activities with increasing tendency; it occurs most commonly in the third to fourth decade of life with a male-to-female ratio of 5–10:1. Ruptures are caused predominantly by a sudden, unexpected overextension of the tendon while direct trauma is less frequent. The recommended treatment of the injury remains controversial. In Germany, due to the good functional results, the open surgical repair represents the standard therapy since many years. The open suture technique offers the advantage of a lower re-rupture rate but is associated with the risk of wound-related complications including infection. By percutaneous suture techniques a significant decrease in the rate of infections and complications in wound healing could be achieved by minimal-access with reduced soft tissue trauma; on the other hand an increased rate of lesions of the sural nerve is reported. Dynamic imaging assessment of ultrasound or MRI allows a more accurate localisation of the ruptured ends of the tendons which is the prerequisite for the non-operative primary functional treatment of Achilles tendon ruptures. This conservative treatment regime is recommended when adaptation of the ends of the ruptured tendon is possible in 20° plantar flexion of the foot. Moreover, the desired level of daily activity and the patients’ degree of compliance has to be considered. Operative management should be avoided in the elderly patient or patients with risk factors like immunosuppressive therapy, diabetes mellitus, steroid use or failure to comply.     

Retrospective patient outcome evaluation after semi-rigid stabilization without fusion for degenerative lumbar instability

Postero-lateral fusion by means of rod-and-screws/hooks constructs is still the gold standard in the treatment of lumbar degenerative spinal diseases. However, fusion remains fraught with a high risk of adjacent levels degeneration, sometimes leading to suboptimal clinical outcomes. Dynamic stabilization is supposed to compensate for disadvantages associated with rigid fusion. Preliminary results of spinal stabilization by means of dynamic devices show encouraging results. Therefore, the aim of the present study is to retrospectively evaluate the overall long term outcome and the condition of the adjacent discs to fused segments in an active population of 33 patients with back pain associated with lumbar instability, who underwent postero-lateral dynamic stabilization by means of a dynamic rod-and-screws construct, without fusion. The mean follow-up was 45 months. Clinical and radiological data, pain, function, return to work rate and patient satisfaction index were recorded to assess the overall patient outcome. The results show a very low rate of post-operative complications. No spontaneous fusion was noted in any patient. Pain, both lumbar and radicular, was totally relieved in most of the patients and the functional results were good or excellent in 76% of patients. Most of the patients resumed their previous activities; the return to previous work rate was 87.5%. Ninety-four percent of the patients were fully satisfied with the results. The preservation of both instrumented levels and the adjacent ones was observed in 90% of patients. Although the present series is rather limited in number, the results of the study are encouraging and in agreement with most findings in the literature. As the results are sustained at a mid and long term, the authors believe that the stabilization without fusion by means of semi-rigid/dynamic systems is an interesting alternative to classical fusion as long as the indications are strictly defined.
