Pathologies of the extensor carpi ulnaris (ECU) tendon are often due to de Quervain's tenosynovitis of the first dorsal compartment among the wrist tendon pathologies. A common cause for tendinitis and tenosynovitis of the ECU tendon is its dislocation. ECU dislocation is unique among all wrist tendon injuries due to its typical location within a fibro-osseous tunnel bordered by a fibrous sheath, which is termed as the subsheath. The subsheath is the main anatomic structure keeping the ECU tendon within the tunnel...

Shockwave therapy has found its place in the medical treatment of various diseases of the locomotor system such as acute fracture, nonunion, chronic tendinitis and pseudarthrosis. Focused shock waves enable maximum energy in the therapeutic zone, and depth of penetration can be adjusted. Radial shockwave therapy primarily affects superficial tissues, so its application in medicine is doubtful. Our study aimed to assess long bone fracture healing in regard to soft tissues. For this investigation, 84 female Wistar rats were divided into a focused shockwave group (n=36), a radial shockwave group (n=36) and a control group (n=12)...

The application of a series of extremely high accelerative motor-driven quick releases while muscles contract isometrically (i.e. slack test) has been proposed to assess unloaded velocity in human muscle. This study aimed to measure gastrocnemius medialis fascicle (VF ) and tendinous tissues shortening velocity during motor-driven quick releases performed at various activation levels to assess the applicability of the slack test method in human. Maximal fascicle shortening velocity and joint velocity recorded during quick releases and during fast contraction without external load (ballistic condition) were compared...

Economic pressure highlights the critical need for appropriate diagnosis and treatment of various shoulder pathologies since under-diagnosis and under-treatment can result in increased costs to society in the form of disability and lost production. On the other hand, aggressive over-treatment can further inflate already burgeoning health-care costs and potentially harm the patient. Therefore, it is crucial to distinguish the indications between operative and nonoperative management, especially in common shoulder pathologies such as rotator cuff tears, anterior shoulder instability, biceps tendinitis, lesions to the acromioclavicular joint, and proximal humeral fractures...

Injuries to the distal biceps occur at the tendinous insertion at the radial tuberosity. Distal biceps injuries range from tendinosis to partial tears to non-retracted and retracted complete tears. Acute and chronic complete tears result from a tendinous avulsion at the radial tuberosity. Acute tears result from a strong force exerted on an eccentric biceps contraction, leading to tendon injury.

Ischiofemoral impingement is a source of hip pain derived from impingement between the lesser trochanter and the ischium. Lesser trochanter excision has been recommended for recalcitrant ischiofemoral impingement through either an anterior or posterior approach. However, neither of these approaches involves refixation of the iliopsoas tendon. We describe an endoscopic procedure involving anterior trochanter-plasty, minimizing the risk of sciatic complications, with refixation of the partially detached iliopsoas tendinous insertion, potentially minimizing compromise to hip flexion strength and anterior hip stability...

BACKGROUND: Fractures of the talar neck and body can be fixed with percutaneously placed screws directed from anterior to posterior or posterior to anterior. The latter has been found to be biomechanically and anatomically superior. Percutaneous guidewire and screw placement poses anatomic risks for posterolateral and posteromedial neurovascular and tendinous structures. The objective of this study was to determine the injury rate to local neurovascular and tendinous structures using this technique in a cadaveric model...

OBJECTIVE: To estimate the prevalence and distribution of asymptomatic monosodium urate (MSU) crystal deposition in sons of people with gout. METHOD: People with gout were mailed an explanatory letter enclosing a postage-paid study-pack to mail to their son(s) ≥20 years old. Sons interested in participating returned a reply-slip and underwent telephone screening. Subsequently they attended a study-visit for blood and urine collection, and musculoskeletal ultrasonography performed blind to serum urate (SU)...

Tendon and ligament injuries are a common source of lameness in the athletic horse. Although tendons and ligaments have the ability to spontaneously heal, lesions tend to fill with biomechanically inferior fibrous tissue such that the horse is prone to reinjury. Regenerative medicine is used to improve quality of repair tissue and prevent reinjury. Platelet-rich plasma, stem cells, and autologous conditioned serum are the most commonly used orthobiologics in the horse. A tailored rehabilitation program is key to returning horses to athleticism following injury...

PURPOSE: The following research aimed to investigate the prevalence and anatomical features of the axillary arch (AA) - a muscular, tendinous or musculotendinous slip arising from the latissimus dorsi and that terminates in various structures around the shoulder girdle. The AA may complicate axillary lymph node biopsy or breast reconstruction surgery and may cause thoracic outlet syndrome. METHODS: Major electronic databases were thoroughly searched for studies on the AA and its variations...

Background: Popliteal artery entrapment syndrome (PAES) is a very rare pathology that can cause lower extremity ischemia in healthy young people. Anomalous anatomic relationships between the popliteal artery (PA) and the surrounding musculo-tendinous structures cause PAES. We present 31 patients with PAES in 35 limbs that were treated surgically in our clinic within a 12-year period. Patients and Methods: From 2001 to 2015, 31 patients (mean age: 32 ± 7.4 years) underwent surgery for PAES...

Damage to the hand in patients suffering from gout is rare and is often detected at an advanced stage. The main clinical manifestations are the appearance of subcutaneous tophi at the finger joints. Other clinical manifestations of osteoarticular, tendinous or neurological lesions have been described in the hand and are often difficult to diagnose. In the majority of cases, surgery and adequate medical care with a suitable anti-gout treatment will allow the patient to recover normal hand function. However, surgical treatment is rare and is only performed after several months of carefully adapted medical treatment...

BACKGROUND: Familial hypercholesterolemia is a genetic lipoprotein disorder characterized by elevated plasma low-density lipoprotein cholesterol level, (tendinous xanthomas, xanthelasmas, and premature arcus corneus) and early onset atherosclerotic cardiovascular disease. Familial hypercholesterolemia is caused by mutations in the low-density lipoprotein receptor, apolipoprotein B or proprotein convertase subtilisin/kexin type 9 genes. Rare mutations in low-density lipoprotein receptor adapter protein 1, APOE p...

Displacement of the myotendinous junction (MTJ) obtained by ultrasound imaging is crucial to quantify the interactive length changes of muscles and tendons for understanding the mechanics and pathological conditions of the muscle-tendon unit during motion. However, the lack of a reliable automatic measurement method restricts its application in human motion analysis. This paper presents an automated measurement of MTJ displacement using prior knowledge on tendinous tissues and MTJ, precluding the influence of nontendinous components on the estimation of MTJ displacement...
