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]

• Disturbance of Growth

  Each child presented at a different age, with differing degrees of deformity and growth disturbance. Both growth and remodeling potential influenced the choice of treatment and outcome. [ncbi.nlm.nih.gov]

• Periodontitis

  We report here advanced periodontitis with severe gingival inflammation in a 29-year-old Larsen's syndrome patient. Bacterial culture of subgingival plaque identified the periodontal pathogens that were present in numbers above the normal range. [ncbi.nlm.nih.gov]

• Neglect

  Treatment of bilateral hip dislocations is best neglected. Finally, the spinal status of these children must be monitored throughout their life. [ncbi.nlm.nih.gov]

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]

Neither the natural history nor the optimal treatment of cervical spine anomalies in Larsen's syndrome has been clearly defined. [ncbi.nlm.nih.gov]

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]

Prognosis LS does not affect life-expectancy. The documents contained in this web site are presented for information purposes only. [orpha.net]

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]

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]
