Hypothenar hammer syndrome in sports

1996

Repetitive blunt trauma or single severe trauma to the hypothenar region may lead to traumatic thrombosis of the distal ulnar artery (hypothenar hammer syndrome, HHS). In the sports-related literature we found and analysed isolated cases attributed to injuries sustained during sporting activities such as baseball, badminton, handball, football, frisbee, softball, karate, weight-lifting and hockey. Further, we report the case of an amateur golf player with ischaemic symptoms of his left hand, where angiography revealed filling defects in the digital arteries associated with a corkscrew-like configuration of the distal ulnar artery. Magnetic resonance imaging (MRI) scan demonstrated, at the l…

Behandlung und Ergebnisse nach Rupturen des Ligamentum patellae

1993

Die vergleichsweise seltenen Rupturen des Ligamentum patellae werden im jungen Erwachsenenalter durch ein direktes Trauma ausgelost; beim alteren Menschen fuhrt ein inadaquates Ereignis zur Spontanruptur. Im eigenen Krankengut der Jahre 1980 bis 1990 stehen acht traumatische Rupturen (Durchschnittsalter: 26,5 Jahre) elf Spontanzerreisungen (Durchschnittsalter: 57,5 Jahre) gegenuber. Zur operativen Wiederherstellung der zerrissenen oder ausgerissenen Patellarsehne gibt es keine Alternative; Sehnennaht und entlastende Drahtschlaufe ermoglichen unter fruhrunktioneller Nachbehandlung ein gutes funktionelles Resultat mit leichteren bleibenden Muskelverschmachtigugen und geringen Bewegungseinschr…

3D-CT von Frakturen: Vergleich von Volumen- und Oberflächen-Rekonstruktionen

1998

Purpose The comparison of volume rendering (VR) and surface rendering (SSD) for demonstrating fractures from spiral-CT data. Materials and methods Standardized VR and SSD projections were produced from 50 spiral CT scans of 50 consecutive patients with fractures. Appropriate multiplanar reformattings (MPR) were used as the standard. Results SSD provided sufficient information in 31/50 cases. Results of VR were not significantly different (33/50). VR was superior in demonstrating 6/7 craniofacial fractures and 3/3 calcaneal fractures. SSD was superior for visualizing 2/3 shoulder fractures and 2/2 elbow fractures. Conclusion VR is a flexible technique for the depiction of fractures and the a…

Locking plates for corrective osteotomy of malunited dorsally tilted distal radial fractures: a biomechanical study.

2005

The purpose of the study was to compare the biomechanical properties of five different palmar fixation plate designs in a distal radius osteotomy cadaver model. A 1 cm metaphyseal osteotomy gap was made to simulate a corrective osteotomy and the osteotomy plated. Axial load was applied to the distal end of each construct by a material testing machine under control of a motion analysis video system. The specimens were arranged into five implant groups of eight specimens each. No test group developed deformity and movement of the fracture gap greater than 2 mm with a load of 100 N. Increasing the load to 250 N revealed statistically significant differences in stiffness and failure load betwe…

Die Röntgenstrahlenbelastung der Hände der Operateur bei Marknagelosteosynthesen

1996

Bei 41 Marknagelungen (21 unaufgebohrte und neun aufgebohrte Tibiamarknagelungen sowie vier unaufgebohrte und sieben aufgebohrte Femurmarknagelungen) trugen Operateur und 1. Assistent Ringdosimeter am dominanten Zeigefinger unter dem sterilen Handschuh. Bei Durchleuchtungszeiten von durchschnittlich 4.6 min pro Eingriff lag die mittlere Strahlenbelastung der Finger der Operateur bei 1.27 mSv und die der 1. Assistenten bei 1,19 mSv. Extrapoliert man den Gesamtmittelwert der ermittelten Strahlenbelastung der Hand der Operateure und 1. Assistenten von 1,23 mSv, wurde der gesetzlich zugelassene Grenzwert fur beruflich strahlenexponierte Personen der Gruppe A von 500 mSv erst bei 407 Marknagelos…

Reaction of the bone structure to methotrexate-Palacos flow y. Experimental investigations in animals.

1989

With the combined osteosynthesis of pathological fractures in association with tumors and/or metastases in mind, E. Merck (Darmstadt, FRG) developed a bone cement containing a cytostatic agent, methotrexate-Palacos flow y (MTX-Pf). The animal-experimental study presented here investigates the tolerability of MTX-Pf in the femurs of rabbits with lateral comparison. In these investigations we used both the concentration of 0.63% MTX, as is currently used in standard clinical surgery, as well as a much higher concentration of 2.5% MTX. The histological sections were investigated using microradiographic methods and provided no indication of any significant differences between the femora with th…

Die “durchgeschobene” Kondylenplatte

1995

Zwolf langstreckige Stuck-und Trummerfrakturen des Oberschenkels, die den metaphysaren (siebenmal proximal, funfmal distal) und gleichzeitig auch den diaphysaren Bereich betrafen, wurden mit extrem langen Kondylenplatten (16 bis 20 Loch) osteosynthetisch versorgt. Die Kondylenplatten wurden uber einen proximalen und einen distalen Zugang eingebracht, der Musculus vastus lateralis in allen Fallen im Frakturbereich vollstandig unversehrt belassen. Nach typischer Vorbereitung des Klingenlagers mit dem Plattensitzinstrument wurden die Kondylenplatten mit der Klinge auf den Operateur zeigend hinter dem Musculus vastus lateralis eingeschoben, und anschliesend unter Drehung der Platten um 180° sow…

Endoscopic carpal tunnel release: results with special consideration to possible complications.

2000

Single-portal endoscopic carpal tunnel release (Agee technique) was carried out in 148 patients. Of these, 100 were examined clinically and electrophysiologically 1 day before surgery and 1 and 3 months thereafter. Ten patients experienced transient ulnar neuropraxia and two patients complained postoperatively of intense pain in the middle and ring fingers. Three patients suffered residual symptoms. In one of these an incomplete release of the distal portion of the retinaculum flexorum was suspected and later confirmed by magnetic resonance imaging. Another patient had applied for pension due to problems associated with a vertebral fracture in addition to his carpal tunnel symptoms. A third…

Minimally invasive plate fixation in femoral shaft fractures

1997

Bridge-plating with its advantages in terms of vascularity and bone healing is a well established procedure today in the treatment of comminuted femoral fractures. Bridge-plating means that the fracture site is not interfered with during the operative procedure. This paper introduces a surgical technique in which the plate is inserted through isolated proximal and distal incisions only, behind the vastus lateralis. Alignment is secured by the plates, the fracture site remains untouched, fixation and screw insertion is restricted to the proximal and distal main fragments. Longitudinal femoral fractures extending right into the trochanteric and or condylar areas are the main indication for mi…

Ergebnisse nach Implantation von zementfreien metallspongiösen Hüftprothesen

1994

72 Huftgelenke mit zementfreier metallspongioser Huftprothese wurden zwei bis sieben Jahre (mittlere Nachuntersuchungszeit 43 Monate) nach der Implantation klinisch und rontgenologisch kontrolliert. Bei funf Patienten muste die zementfreie Prothese wegen Lockerung (ausbleibende knocherne Einheilung n=2, Pfannenlockerung infolge operationstechnischer Fehler n=3) gewechselt werden. Aufgrund der klinischen Befunde konnten 88% von 67 Huften mit sehr gut bzw. gut, 9% mit befriedigend und 3% mit unbefriedigend bewertet werden. 10% der Patienten klagten noch uber Oberschenkelschmerzen. Die typischen, rontgenologisch erkennbaren, knochernen Reaktionen des Implantatlagers werden beschrieben, eine In…
