BACKGROUND: For young patients with proximal lesions of long head of biceps tendons with high requirements for upper limb movement, the commonly tendon fixation includes interface extrusion screw fixation and suture anchor ligation fixation. At present, there are few clinical reports and no conclusion on the comparison of the clinical efficacy of the two. OBJECTIVE: To compare the clinical efficacy of proximal lesions of long head of biceps tendons by interface extrusion screw fixation and suture anchor ligation fixation in arthroscopy. METHODS: Totally 52 patients with proximal lesions of long head of biceps tendons treated in Nanchang Hongdu Hospital of TCM from January 2019 to December 2020 were enrolled and randomly divided into interface extrusion screw group (n=29) and suture screw group (n=23). The patients in both groups were subjected to interface extrusion screw fixation and suture anchor ligation fixation in arthroscopy, respectively. Before, 1, 3, 6, and 12 months after operation, and during last follow-up, shoulder visual analog scale score, the American shoulder and elbow surgeons score, and range of motion in anterior flexion of shoulder and internal and external rotation at elbow flexion 90° were compared between the two groups. Elbow flexion muscle strength, reoperation rate and complication rate (Popeye sign) were compared between the two groups at the last follow-up. RESULTS AND CONCLUSION: The visual analog scale scores, the American shoulder and elbow surgeons score and shoulder range of motion in anterior flexion of shoulder and internal and external rotation at elbow flexion 90° were significantly improved after operation compared with those before operation in both groups (P < 0.05). There were no significant differences in visual analog scale scores, the American shoulder and elbow surgeons score and shoulder range of motion in anterior flexion of shoulder and internal and external rotation at elbow flexion 90° between the two groups before and at various time points after operation (P > 0.05). At the last follow-up, the elbow flexion muscle strength of the two groups reached above grade IV, and the results showed no significant difference. Popeye syndrome occurred in the interface extrusion screw group (14%) and reoperation was performed (7%). In the suture screw group, the incidence of Popeye sign was 4.3% and the reoperation rate was 0%. The incidence of Popeye sign and the reoperation rate were not significantly different between the two groups (P > 0.05). For the proximal lesion of long head of biceps tendons, both the interface extrusion screw fixation and the suture anchor ligation fixation in the arthroscopy can effectively relieve shoulder pain and improve shoulder function within one year and the clinical effects of the two methods are equivalent. © 2023, Publishing House of Chinese Journal of Tissue Engineering Research.

The flexor system of the fingers consisting of flexor tendons and finger pulleys is a key anatomic structure for the grasping function. Athletes and manual workers are particularly at risk for closed injuries of the flexor system: ruptured pulleys, ruptures of the flexor digitorum profundus from its distal attachment (“jersey finger”), and less frequently, ruptures of the flexor digitorum superficialis and of the lumbrical muscles. Open injuries vary more and their imaging features are more complex since tendons may be torn in several locations, the locations may be unusual, the injuries may be associated with nerve and vascular injuries, fibrosis… Sonography is the best imaging modality to associate with the clinical exam for it allows an experienced physician to make an accurate and early diagnosis, crucial to appropriate early treatment planning. 相似文献

The effect of tendon excursion velocity on longitudinal median nerve displacement: Differences between carpal tunnel syndrome patients and controls 下载免费PDF全文

The subsynovial connective tissue (SSCT) is a viscoelastic structure connecting the median nerve (MN) and the flexor tendons in the carpal tunnel. Increased strain rates increases stiffness in viscoelastic tissues, and thereby its capacity to transfer shear load. Therefore, tendon excursion velocity may impact the MN displacement. In carpal tunnel syndrome (CTS) the SSCT is fibrotic and may be ruptured, and this may affect MN motion. In this study, ultrasonography was performed on 14 wrists of healthy controls and 25 wrists of CTS patients during controlled finger motions performed at three different velocities. Longitudinal MN and tendon excursion were assessed using a custom speckle tracking algorithm and compared across the three different velocities. CTS patients exhibited significantly less MN motion than controls (p ≤ 0.002). While in general, MN displacement increased with increasing tendon excursion velocity (p ≤ 0.031). These findings are consistent with current knowledge of SSCT mechanics in CTS, in which in some patients the fibrotic SSCT appears to have ruptured from the tendon surface. © 2015 Orthopaedic Research Society.

“阳气者,精则养神,柔则养筋”出自《素问·生气通天论》,历代注家多有不同注释.从阳气升降浮沉之圆运动的角度出发,提出新的见解,认为其内涵为人体的阳气与自然界的阳气一样,是持续的有规律的运动,总体表现出与太阳类似的升降浮沉之圆运动状态.只有阳气正常的收敛与潜藏,才能营卫血气调和而养神;只有阳气适时的萌动与升发,才能气血调达而筋肉有力.可见“阳气者,精则养神,柔则养筋”表达了阳气变动不居的特点,及其在不同的状态下对人们神与形的影响. 相似文献

Clinical implications of acute injuries of the os peroneum have been described, with the recommendation in some cases being the excision of the bone fragments. We describe the spectrum of sonographic appearances associated with pain in the region of the os peroneum, document associated peroneal tendon pathology, and describe the use of sonography to direct and guide therapeutic and/or diagnostic injections. All sonographic examinations in our ultrasound database from Jan 1, 2001–Jan 30, 2007 with the words “os peroneum” were reviewed. Patients were cross-referenced in our radiology database to find relevant foot or ankle radiographs for correlation. There were 47 patients (18 men and 29 women, age range 16 to 83) referred for sonographic evaluation of lateral foot and/or ankle pain who had an os peroneum identified during the sonographic evaluation. Eighteen patients were referred specifically for targeted injection of the lateral ankle, including peroneal tendon sheath injections (N = 10), calcaneocuboid joint injections (N = 1), and injections around symptomatic os peroneum (N = 7). All 47 patients had tendinosis of the peroneus longus, in varying degrees of severity. Radiographs were available for correlation in 28 patients. The causes of lateral ankle pain with a co-existent os peroneum are multifactorial and may not directly relate to the presence of an os peroneum. Ultrasound can be of value in separating out the specific etiology for pain, as well as provide a method for problem solving by the performance of targeted diagnostic or therapeutic injections in the lateral ankle. 相似文献

Tissue engineering may play a major role in the treatment of rotator cuff tendon lesions through replacement of an injured
tendon segment. Tendons have very poor spontaneous regenerative capabilities, and despite intensive remodelling, complete
regeneration is never achieved and the strength of tendon and ligaments remains as much as 30% lower than normal even months
or years following an acute injury. Tendons seem to be the least complex of the connective tissues with respect to their composition
and architecture and this leads to the expectation that they would be more amenable to tissue engineered approaches than other
tissues. An accurate literature revision was done in order to know the state of the art of tissue engineering therapies in
the field of rotator cuff regeneration. The following techniques of tissue engineering were considered: local injection of
stem cells or growth factors, gene transfer, in situ tissue engineering and in vitro production of bioengineered tendons to be further transplanted in the lesion site. So far, few experimental or clinical studies
have been done on tendon tissue engineering compared to the extensive work on other tissues of orthopaedic interest, such
as bone and cartilage. The existing studies are related to the following tissue engineering methodologies: gene transfer,
in situ tissue engineering and in vitro production of bioengineered tendons. In our opinion the previously described literature revision showed the necessity for
future studies in this area also because of recent advances in biological and bioactive scaffolds. 相似文献

Summary
Objectives: To assess complaints and clinical findings of rheumatoid hand flexor tendon disease in relationship to the anatomical site
and the type of lesion in order to improve the diagnosis and enable early operative treatment with preservation of hand function.
Methods: 123 patients of the hands of 78 patients (66 female, 12 male) with a mean age of 57 years were analyzed retrospectively.
Preoperative complaints and clinical findings were recorded according to their frequency. Three different types of flexor
tendon disease were distinguished intraoperatively: isolated tenosynovitis, tenosynovitis with tendon lesion, and complete
tendon rupture.
Results: 188 tendons showed isolated synovitis, 208 had a tendon lesion with synovitis, and 30 tendons a rupture. Tenosynovitis was
found in the palm and wrist mainly. The 2nd, 3rd and 4th finger were most frequently involved. 81 tendon adhesions, 12 nodules,
63 superficial lesions and 52 defects were detected. These lesions were found mainly in the palm and the second and third
ray. The profundus tendon was affected most often. Ruptures were detected most often in the wrist caused by bony spurs and
tenosynovitis. A clinical difference between tenosynovitis with and without tendon lesion was not found. However, complaints
and findings were different in the digit, palm, wrist and forearm. Ruptures had characteristic clinical findings.
Conclusions: Rheumatoid flexor tendon disease is common. Tenosynovitis is often accompanied by tendon lesions. Ruptures occur as disease
progresses. Exact assessment of complaints and clinical findings is mandatory to diagnose and localize flexor tendon disease.
Early operative intervention helps to preserve the function of the hand.

INTRODUCTION: There is growing use of the Todaro tendon and triangle of Koch as anatomic icons for invasive cardiac electrophysiologists. Reasons exist to doubt this validity. METHODS AND RESULTS: Histologic sections were prepared from 96 anatomically normal human hearts. The study area extended from the crista supraventricularis to the eustachian valve and included the AV node and His bundle. This encompasses any tendon of Todaro. Because the purported triangle of Koch includes the tendon of Todaro, all of Koch's available publications were examined. The tendon of Todaro is absent in only one fourth of infant hearts, but in two thirds of adult hearts. Tendons present were less often single than double or more, rarely exceeded 4 mm in length, and were seldom > 1 mm in diameter. Tendons usually originated from the central fibrous body and ended in the eustachian valve. Their origin most often was over the His bundle or its junction with the AV node, rather than the AV node. Tendons were primarily composed of collagen. Koch never described any triangle or acknowledged existence of tendons of Todaro. CONCLUSION: Todaro tendons are too often absent (or multiple) to warrant use as anatomic landmarks. Without this side of the supposed triangle of Koch, the entire tendon and triangle concept collapses and should be abandoned. There are numerous far more constant anatomic landmarks available to orient one to the human AV node and His bundle; these are briefly reviewed. 相似文献
