Generalized arterial calcification of infancy (GACI) is an autosomal recessive disorder characterized by early onset of extensive mineralization of the cardiovascular system. The classical forms of GACI are caused by mutations in the ENPP1 gene, encoding a membrane-bound pyrophosphatase/phosphodiesterase that hydrolyzes ATP to AMP and inorganic pyrophosphate. The asj-2J mouse harboring a spontaneous mutation in the Enpp1 gene has been characterized as a model for GACI. These mutant mice develop ectopic mineralization in skin and vascular connective tissues as well as in cartilage and collagen-rich tendons and ligaments...

BACKGROUND: Musculoskeletal disorders (MSD) are the leading cause of sickness absence (SA) in Spain and the second in Catalonia. A greater knowledge of this field could allow the refocusing of social protection policies and interventions to reduce their frequency and duration. The objective of the study was to describe the characteristics and duration of SA due to MSD in Catalonia between 2007 and 2010. METHODS: The study population included all incident SA episodes due to MSD during the period 2007-2010, registered in the Institut Català d'AvaluacionsMèdiques (ICAM) database...

BACKGROUND: Arthroscopic treatment of calcific deposits of rotator cuff tears has been described with successful results in the general population. However, despite the high frequency of this condition, there is no information in the literature regarding arthroscopic treatment of rotator cuff calcifications in athletes. PURPOSE: To analyze the time to return to sport, clinical outcomes, and complications of complete arthroscopic removal of intratendinous calcific deposits and repair of the tendon lesion without acromioplasty in athletes...

REVIEW
Salvatore Gitto, Anna Guja Draghi, Chandra Bortolotto, Ferdinando Draghi
This review aims to provide the radiologist with simple and systematic guidelines for evaluation of the Achilles tendon after complete rupture repair. Currently, there is a plethora of nonsurgical and surgical treatments, but sonographic examination has shown no significant differences between them. A systematic analysis of several parameters (morphologic characteristics, structure, color Doppler vascularization, and mobility) should be undertaken. Morphologically, the repaired tendon is larger, wider, or both...

This study investigates the histological background of torn rotator cuff tendons, evaluates the stability of newly synthesized collagen by measuring the hydro-xyproline content and attempts to correlate these findings with the clinical outcome after reconstruction of the rotator cuff. Sixty-one patients underwent reconstruction for a -rotator cuff tear. They were evaluated preoperatively with the Constant-Murley score, MRI and ultrasound. Biopsy samples were taken from chronic rotator cuff tears and histological analysis was performed...

BACKGROUND: Calcific deposits in tendon, muscles, and periarticular areas are very common. Heterotopic ossification of the rectus femoris (HORF) is a rare condition, and several theories exist regarding the etiopathogenesis, which appears to be multifactorial with traumatic, genetic, and local metabolic factors involved. Although HORF typically responds to nonoperative treatment, when this approach fails, endoscopic treatment is a minimally invasive technique to address the pathology...

Calcific tendinopathy of the shoulder is a common condition caused by calcium hydroxyapatite crystals, affecting the tendons of the rotator cuff. Among uncommon complication, one is the migration of the calcium in the subacromion-subdeltoid bursa. More rare is the intraosseous migration. We present four cases of an even more rare condition, not well described in literature yet, the intramuscular migration of calcium.

Shockwave treatments are commonly used in the management of tendon injuries and there is increasing evidence for its clinical effectiveness. There is a paucity of fundamental (in vivo) studies investigating the biological action of shockwave therapy. Destruction of calcifications, pain relief and mechanotransduction-initiated tissue regeneration and remodeling of the tendon are considered to be the most important working mechanisms. The heterogeneity of systems (focussed shockwave therapy vs. radial pressurewave therapy), treatment protocols and study populations, and the fact that there seem to be responders and non-responders, continue to make it difficult to give firm recommendations with regard to the most optimal shockwave therapy approach...

Exercise is crucial in the management of diabetes mellitus and its associated complications. However, individuals with diabetes have a heightened risk of musculoskeletal problems, including tendon pathologies. Diabetes has a significant impact on the function of tendons due to the accumulation of advanced glycation end-products in the load-bearing collagen. In addition, tendon vascularity and healing may be reduced due to diabetes-induced changes in the peripheral vascular system, and impaired synthesis of collagen and glycosaminoglycan...

Tendinopathies have a multifactorial etiology driven by extrinsic and intrinsic factors. Recent studies have elucidated the importance of thyroid hormones in the alteration of tendons homeostasis and in the failure of tendon healing after injury. The effects of thyroid hormones are mediated by receptors (TR)-α and -β that seem to be ubiquitous. In particular, T3 and T4 play an antiapoptotic role on tenocytes, causing an increase in vital tenocytes isolated from tendons in vitro and a reduction of apoptotic ones; they are also able to influence extra cellular matrix proteins secretion in vitro from tenocytes, enhancing collagen production...

Congenital metabolic disorders are consequence of defects involving single genes that code for enzymes. Blocking metabolic pathways, the defect leads to the shortage of essential compounds, and/or to the accumulation of huge quantities of precursors, which interfere with normal functions. Only few of these diseases are characterized by a clinically significant tendon involvement.Heterozygous Familial Hypercholesterolaemia results from the inheritance of a mutant low-density lipoprotein receptor gene; patients show high cholesterol levels, precocious coronary artery disease, and may develop tendon xanthomata (mainly in Achilles tendon)...

BACKGROUND: We report 8 years of follow-up after decompression to treat cervical myelopathy in a patient with Coffin-Lowry syndrome (CLS). CLS is a rare X-linked semidominant syndrome associated with growth and psychomotor retardation, general hypotonia, and skeletal abnormalities. In this patient, the spinal cord was compressed by calcium pyrophosphate crystal deposition in the cervical yellow ligament (YL). To date, only 1 report has described clinical features after surgery for calcified cervical YL in CLS...

A 37-year-old man presented to the acute knee and sports medicine clinic with atraumatic lateral knee pain. He had point tenderness over the lateral aspect of his knee which had not settled with anti-inflammatory medications. Imaging revealed a large opaque lesion lateral to the knee and although there was no clear mechanism, injury to the posterolateral corner was considered. An MRI subsequently revealed a rare case of calcific tendinitis to the biceps femoris tendon insertion. This condition was self-limiting and did not require interventions such as steroid injections...

Tendon calcification has been widely regarded by researchers to result from the osteogenic differentiation of Tendon-Derived Stem Cells (TDSCs) and ectopic mineralization caused by the calcification of cellular matrix. Recent studies have revealed a correlation between the Mg(2+)/Ca(2+) balance and the degeneration or calcification of tendon tissues. Furthermore, the ATP-P2X/P2Y receptor pathway has been shown to play a decisive role in the process of calcification, with calcium exportation from mitochondria and calcium oscillations potentially representing the cohesive signal produced by this pathway...

Gluteal tendinopathy as well as partial and full-thickness tears of gluteal tendons (gluteus minimus and/or medius tendon) were underestimated as a cause of chronic pain in the past, and treatment was most commonly based on the diagnosis of trochanteric bursitis. Tendinous pathologies can either stay asymptomatic or cause pain and muscular dysfunction, not necessarily being associated with osteoarthritis of the hip 1. As the terminus "rotator cuff tear of the hip" was published in 1997 2, its aetiopathogenesis was reconsidered, resulting in improvements in diagnosis and treatment...
