    Notes: Abstract 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 level of the hamulus ossis hamati, accessory fibres of m. palmaris brevis forming a sling around the ulnar artery. Treatment by resection of the ulnar artery. Treatment by resection of the thrombosed a. ulnaris segment and replacement with an autologous vein graft resulted in complete relief of symptoms. Histological sections revealed partially organized thrombi adherent to the intimal surface with fragmentation of the internal elastic membrane, indicating a traumatic genesis. As the mechanism of injury, we suspected intensive golf playing with the grip style and subsequent motions leading to pressure injury of the hypothenar area and the underlying ulnar artery. Contraction of the anomalous muscle belly may have additionally compressed the artery, slowing down the arterial flow and promoting thrombosis. In most reported cases including our own, it took a relatively long time until the cause of the disease as traumatic was found and accepted. The initial repetitive blunt or single severe trauma initiaing the HHS can easily be overlloked or ignored. After intimal damage of a. ulnaris, the beginning of symptoms may be prolonged and mislead one into thinking the cause is a collagen or vasospastic disease.

    Description / Table of Contents: Zusammenfassung In etwa 25 % der Fälle ist im Erwachsenenalter das Foramen ovale anatomisch offen, funktionell, bedingt durch den höheren Druck im linken Vorhof, aber geschlossen. Wenn z. B. durch eine Lungenembolie ein höherer Druck durch Rechtsherzbelastung im rechten Vorhof entsteht, kann sich ein funktionell normalerweise geschlossenes Foramen ovale wieder öffnen, und durch den eintretenden Rechts-links-Shunt der Weg für eine paradoxen Embolie gebahnt werden. Im vorliegenden Fall traten bei einer Patientin 20 Tage nach operativer Versorgung einer subtrochantären Oberschenkelfraktur mittels Kondylenplatte Wortfindungsstörungen auf. Die deshalb durchgeführte Magnetresonanztomographie (MRT) des Schädels zeigte einen frischen ischämischen Infarkt. Nachdem die übliche Durchuntersuchung mit Duplexsonographie der Karotiden keinerlei Erklärung für den ischämischen Infarkt ergeben hatte, wurde eine paradoxe Embolie über ein offenes Foramen ovale vermutet. Anschließend konnte sowohl duplexsonographisch eine frische Thrombose der V. femoralis superficialis als auch szintigraphisch eine Lungenembolie nachgewiesen werden. Die transösophageale Echokontrastkardiographie stellte ein spontan hämodynamisch wirksames offenes Foramen ovale dar. Der Fall zeigt, daß inapparente Beinvenenthrombosen durch zerebrale Defizite, wie z. B. Wortfindungsstörungen manifest werden können, und veranschaulicht den Pathomechanismus einer paradoxen Embolie.
    Notes: Summary The foramen ovale is anatomically open in 25 % of individuals, but functionally closed by the higher pressure in the left antrum. Right-to-left shunt and subsequent paradoxical embolism may occur when pressure in the left antrum rises, for example, as a result of pulmonary embolism. In the present case we demonstrate a patient who presented 20 days after osteosynthetic treatment of a femoral fracture with word-finding deficits. Cerebral MRT revealed a fresh ischemic insult. Duplex ultrasound of the legs showed a fresh thrombosis of the superficial femoral vein and scintigraphy of the lungs detected pulmonary embolism. Transesophageal contrast echocardiography trapped a hemodynamically spontaneous, open foramen ovale. Duplex ultrasound of the carotid arteries detected no pathological findings. Deep vein thrombosis and pulmonary embolism can be clinically unconspicuous and become manifest by cerebral deficits resulting from paradox embolism and cerebral ischemia.

    Notes: Abstract Diagnostic and clinical features of the frozen shoulder syndrome and the Sudeck syndrome are similar in many aspects. Radioisotope bone scan shows an increased uptake in affected areas in both diseases, while native radiographs show a progressive demineralisation. Measurement of bone mineral density (BMD) by quantitative digital radiography objectified these local decalcification processes in an early stage of the frozen shoulder syndrome; 10 of 12 patients with primary frozen shoulder had BMD decreases greater 21% in the humeral head of the affected shoulder compared to the non-affected side. In the immobilised control group with degenerative changes of the rotator cuff, calcifying tendinitis and shoulder instability (n = 12) and in the group of healthy probands (n = 20), the difference between the affected and non-affected side (left and right humerus of the healthy probands) was only more than 21% in one case each. There are several references in the literature that assume frozen shoulder to be an algoneurodystrophic process; our observations support this hypothesis, possibly leading to earlier diagnoses and extended therapeutic management.

    Notes: Abstract From 1985 to 1995, 417 patients with dislocated medial femoral neck fractures (Garden III–IV) were treated with hemiarthroplasty using a Biolox ceramic head. The average patient age at the time of operation was 81.5 years. A total of 140 survivors was available for follow-up examination with a mean prosthesis longevity of 55.8 months. The Harris hip score recorded a mean of 70.6 points. At the time of follow up, 5 patients had severe hip pain, and in 8 the roentgenographic examination revealed protrusio acetabuli. Five of these 8 patients underwent revision surgery for replacement of the cup, leaving the stem in situ.

    Description / Table of Contents: Zusammenfassung. Ein 75 jähriger Patient stellte sich mit seit 2 Jahren langsam größenprogredienten Raumforderungen unterhalb beider Schulterblätter vor. Anamnestisch bestand ein Zustand nach proximaler Oberarmamputation linksseitig mit folgender prothetischer Versorgung. Klinisch zeigten sich direkt unter den Schulterblattspitzen beidseits 2 faustgroße Tumoren, die fest mit dem tiefer gelegenen Gewebe verwachsen waren. Sowohl magnetresonanztomographisch als auch intraoperativ stellte sich ein infiltratives Wachstum dieser Raumforderungen in die seitliche Thoraxmuskulatur und das Periost der Rippen sowie des Schulterblatts dar, so daß ein maligner Tumor vermutet wurde. Histopathologisch zeigte sich Bindegewebe mit zahlreichen eingelagerten fragmentierten und unregelmäßig konfigurierten elastischen Fasern und unscharfer Begrenzung zum umgebenden Fettgewebe, typisch für ein Elastofibrom. Für Malignität bestand kein Anhalt. Im vorliegenden Fall erscheint es wahrscheinlich, daß eine unphysiologische Belastung der oberen Extremitäten bei dem mit einer linksseitigen Oberarmprothese versorgten Patienten die Entstehung der beidseitigen Elastofibrome begünstigt hat. Das Elastofibrom ist ein seltener, gutartiger, fast immer subscapulär gelegener Weichteiltumor, der bevorzugt bei älteren Frauen auftritt. In etwa 10 % der Fälle findet sich ein bilaterales, meist asynchrones Wachstum. Klinisch und radiologisch stellen Lipome sowie Weichteilsarkome die wichtigsten Differentialdiagnosen dar. Andere seltene Elastofibromlokalisationen an Rumpf, Kopf und Extremitäten werden in der vorliegenden Arbeit aufgeführt.
    Notes: Summary. A 75-year-old man had painless, slowly enlarging tumors in the right and left infrascapular regions. Clinically, the tumors were nontender and semimobile. MR imaging and the operative exploration revealed tumors infiltrating the lateral thoracic muscles and periost of the scapula and underlying ribs. At surgery, the tumors were thought to be malignant, most likely liposarcomas. The histological examination showed the characteristic appearance of elastofibromas with spindle-shaped fibroblasts, which were separated by thick eosinophilic collagenous and elastic fibers. Elastofibromas are benign mesenchymal soft-tissue lesions that mainly affect elderly women. In 10 % of the patients bilateral, often asynchronous tumors are seen. Ninety-nine percent of the lesions are located in the subscapular region. Occasional elastofibromas have been described in the extremities, head, and in the abdominal and thoracic cavities.

    Notes: Abstract Pigmented villonodular synovitis (PVNS) as reviewed in detail elsewhere most frequently involves the knee and finger synovial structures; shoulder involvement is rare: A search through the English literature yielded 18 publications describing 25 cases of PVNS affecting the shoulder joint. Analyzing these reports we found the clinical and radiological findings generally to be nonspecific, often mimicking a malignancy, as in the case presented here of a 16-year-old boy with painful swelling in the area of the left proximal humerus. Magnetic resonance imaging showed a suspected malignant soft tissue mass involving the shoulder capsule and measuring 7.5 × 6 × 4 cm. Preoperatively the patient could recall no trauma; however, postoperatively he did report a distorsion trauma of the affected shoulder following a bicycle accident. Intraoperatively, two tumors were found infiltrating the axillary vessels and nerve and tendon structures originating in the capsule of the shoulder joint. Rapid sections of the tissue revealed no signs of malignancy; further pathohistological examination revealed localized PVNS. Preoperatively, the shoulder joint was not suspected as the primary site of origin of the tumor because the patient had no complaints or functional deficits of the shoulder. The clinical presentation of such a PVNS lesion over the proximal humerus is unusual and to date has only twice been described in the literature.

    Notes: Abstract 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 patient with residual symptoms was rheumatic, and upon reexamination 6 months later he was virtually symptom free. Five of the 148 operations were converted to an open procedure due to poor visualization. A review of literature on carpal tunnel release (biportal Chow technique and uniportal Agee technique) uncovered 31intra- and postoperative complications, including 14 affecting nerve structures, 2 tendon structures, 2 bony structures, and 9 the surrounding tissues. We discuss the most common complications, considering in particular the anatomical characteristics in the carpal tunnel region.
