Zusammenfassung Die polarisationsoptische and histologische Untersuchung des oberen Bicepssehnenabschnittes an 26 Schultern bestätigt, daß die Sehne ihren Ursprung nicht nur, wie allgemein angenommen, am Tuberculum supraglenoidale hat, sondern außerdem -förmig im Labrum glenoidale. Dieser Befund kann phylogenetisch erklärt werden. Im weiteren Verlauf der Sehne können neue Befunde im Bereich des Sulcus bicipitalis erhoben werden. Hier ist regelmäßig ein Mesotenonium nachweisbar, das durch einen bindegewebigen Ausläufer an Sulcusdach oder -grund befestigt ist. Darüberhinaus wird gezeigt, daß das Sulcusdach nicht als Ligament (Ligamentum transversum humeri) anzusprechen ist, es handelt sich vielmehr um Ausläufer der Kollagenfasern von Subscapularis- bzw. Kapselansatz am Tuberculum minus.
Topography of the upper biceps tendon
Summary 26 shoulders are studied by polariscopic and histologic examination. It can be confirmed that the origin of the long biceps tendon is not only at the supraglenoid tubercle, but also -shaped in the glenoid labrum. This finding can be explained by phylogenetic means. Further details are found during the course of the tendon through the bicipital groove. A mesotenonium is seen regularly. This is fixed either to the roof or the ground of the sulcus by a band of connective tissue. It is shown also, that the roof of the groove is not a ligament (ligamentum transversum. humeri) but consists of collagen fibers continuing from the subscapularis and capsular attachment at the lesser tubercle.相似文献

Spatiotemporal progress of nerve regeneration in a tendon autograft used for bridging a peripheral nerve defect 总被引:3,自引:0,他引:3
We have previously shown that a tendon autograft from the rat tail can support regeneration across a gap in the continuity of the rat sciatic nerve. In this study, we characterized the spatiotemporal progress of regeneration in such a graft bridging a 10-mm defect in the sciatic nerve of the rat. Regeneration was assessed 7, 10, 14, or 18 days postoperatively, by immunocytochemistry for axons, Schwann cells, and macrophages and histochemistry for blood vessels. Axonal regrowth into the grafts showed an initial delay period of 6.8 days, whereafter axons grew at a rate of 1.0 mm/day. Schwann cells grew into the grafts from both the proximal and distal nerve segments, proximally just ahead of the axonal front. Macrophages were initially preferentially located at the periphery of the grafts, but gradually increased inside the grafts. Blood vessels entered the grafts from both the proximal and distal aspects of the severed nerve. The onset of vascularization appeared to coincide with axonal regeneration into the grafts. 相似文献

Tear of the distal biceps brachii tendon is an uncommon injury. Ultrasound evaluation of the distal tendon using an anterior approach is often difficult because of technical factors. We describe a new method of ultrasound evaluation of the distal biceps tendon insertion. This involves a posterior approach with the forearm pronated. With pronation of the forearm, the radial tuberosity faces posteriorly, bringing the distal biceps tendon insertion into view. A surgically proven case of distal biceps tendon tear is presented to illustrate our technique. 相似文献

Objective. In magnetic resonance (MR) imaging of the shoulder, oblique coronal images are used for evaluating the supraspinatus tendon
(SST) of patients with suspected rotator cuff tear or impingement. This study aimed to compare orientation of the SST long
axis with planes perpendicular to the glenohumeral joint (GHJ).
Design and patients. The axial scans of 100 consecutive patients referred for MR imaging or MR arthrography of the shoulder were reviewed. Using
the electronic cursors of a computer workstation, the angle of the SST long axis was measured and compared with the angle
obtained through the GHJ utilizing three different landmarks: perpendicular to the joint (GHJ-90), joint–humeral head center
axis (GHJ-H) and joint–scapular body axis (GHJ-S).
Results. Differences in angulation between axes of the SST and the three GHJ axes averaged only about 5° [range of means 4.5–5.3°,
range of standard deviation (SD) 3.8–4.6°]. In the majority of shoulders, angular differences measured 4 or less for all SST/GHJ
comparisons. Similarly, small angular differences in the three GHJ axes were found: 4.5° (SD 3.3°) for GHJ-90/GHJ-S, 5.0°
(SD 4.0°) for GHJ-S/GHJ-H and 2.9° (SD 3.0°) for GHJ-90/GHJ-H. Correlation between the GHJ-90 and GHJ-H axes was particularly
good, with differences of 4° or less in 84% of shoulders. The orientations of the GHJ axes and that of the SST long axis are
comparable.
Conclusion. The GHJ may potentially be used as a landmark for obtaining oblique coronal images of the SST.

目的探讨陈旧性跟腱断裂的手术方式。方法对62例陈旧性跟腱断裂患者按早期、后期分别采用腓骨短肌转位联合肌腱瓣翻转和Bosworth法修复治疗,比较两种方法治疗效果。结果62例均获随访,时间8个月~6年,腓骨短肌转位联合肌腱瓣翻转组优良率为90.63%,Bosworth法修复组优良率为73.33%,两组差异有显著性(P〈0.01)。结论采用腓骨短肌转位联合肌腱瓣翻转修复治疗陈旧性跟腱断裂,术后并发症少,能显著提高疗效。 相似文献
