Average 4.1 of 25 Ratings Topic Images summary Larsen's Syndrome is a rare genetic disorder caused by mutations in filamin B and carbohydrate sulfotransferase 3 deficiency, that presents with characteristic findings of ligamentous hyperlaxity, abnormal [orthobullets.com]
Three cases of Larsen's syndrome in siblings are presented to illustrate a paradigm for the age-related treatment of deformity. Each child presented at a different age, with differing degrees of deformity and growth disturbance. [ncbi.nlm.nih.gov]
While arthrogryposis means “stiff joints” and presents with the absence of muscles, or ones that are stiff and weak, Larsen Syndrome has dislocated joints and the muscles are present. [paleyinstitute.org]

Workup
Special features in the radiologic workup should be sought after so as to plan staged surgical procedures. Conventional principles of planning of fusion levels are inadequate. Early treatment is advocated, as the neurologic compromise is reversible. [ncbi.nlm.nih.gov]
Treatment
Neither the natural history nor the optimal treatment of cervical spine anomalies in Larsen's syndrome has been clearly defined. [ncbi.nlm.nih.gov]
Treatment is usually open reduction for joint dislocations and early posterior spinal fusion for cervical kyphosis to prevent neurological deterioration. [orthobullets.com]
Prognosis
Prognosis LS does not affect life-expectancy. The documents contained in this web site are presented for information purposes only. [orpha.net]
Prognosis The effects of the syndrome vary markedly from person to person. Therefore, prognosis is based on the findings in a given individual. [encyclopedia.com]
The prognosis of children who have LS is variable and most affected persons have moderate symptoms that can be treated, allowing for a relatively normal life span. In severe forms of LS the prognosis can be poor. [jcnonweb.com]
What is the general prognosis for Larsen Syndrome? If Larsen Syndrome is caught early, most individuals can lead healthy lives with normal lifespans. [checkorphan.org]
[ edit ] While Larsen syndrome can be lethal if untreated, the prognosis is relatively good if individuals are treated with orthopedic surgery, physical therapy, and other procedures used to treat the symptoms linked with Larsen syndrome. [7] See also [en.wikipedia.org]
Etiology
These novel congenital anomalies further support the etiology of Larsen's syndrome as a generalized mesenchymal disorder, since they arise from a defective process of embryonal induction involving mesenchymal tissue. [ncbi.nlm.nih.gov]
Epidemiology Incidence estimated to be 1 in 100,000 live births Etiology Genetics autosomal dominant (AD) and recessive (AR) inheritance patterns AD linked to a mutation of the gene encoding filamin B AR linked to carbohydrate sulfotransferase 3 deficiency [orthobullets.com]

Etiology LS is due to missense mutations or small in-frame deletions in the FLNB gene (localized to 3p14.3) that encodes cytoskeletal protein filamin B. [orpha.net]

Epidemiology Larsen's syndrome with the same frequency develops both in men and in women. By very rough estimates, this disease occurs in a newborn of a hundred thousand. This, fortunately, is a rarity. [acikgunluk.net]

The ichthyosis (usually evident at birth) may be seen in some patients after the first year of life. [1] Pathophysiology Sjögren-Larsson syndrome (SLS) is due to deficient activity of fatty aldehyde dehydrogenase (FALDH), an enzyme required to oxidize [emedicine.medscape.com]
Prevention
Treatment is usually open reduction for joint dislocations and early posterior spinal fusion for cervical kyphosis to prevent neurological deterioration. [orthobullets.com]
The surgeon who undertakes the correction or prevention of these deformities must face the problem of and, it is hoped, use, growth potential from open physes and the progressive loss of remodeling capacity with advancing age. [ncbi.nlm.nih.gov]
How Can You Prevent SLJ Syndrome? The most important thing you can do to prevent getting SLJ is to stop doing an activity that causes pain in your knee at the first signs of irritation. Then, try to limit your activity until the pain goes away. [kidshealth.org]
