The Musculoskeletal Manifestations of Marfan Syndrome: Diagnosis, Impact, and Management

Abstract

Purpose of review: Marfan syndrome (MFS) is an autosomal dominant heritable disorder of fibrillin-1 (FBN1) with predominantly ocular, cardiovascular, and musculoskeletal manifestations that has a population prevalence of approximately 1 in 5-10,000 (Chiu et al. Mayo Clin Proc. 89(1):34-42, 146, Dietz 3, Loeys et al. J Med Genet. 47(7):476-85, 4).

Recent findings: The vascular complications of MFS still pose the greatest threat, but effective management options, such as regular cardiac monitoring and elective surgical intervention, have reduced the risk of life-threatening cardiovascular events, such as aortic dissection. Although cardiovascular morbidity and mortality remains high, these improvements in cardiovascular management have extended the life expectancy of those with MFS by perhaps 30-50 years from an estimated mean of 32 years in 1972 (Dietz 3, Gott et al. Eur J Cardio-thoracic Surg. 10(3):149-58, 147, Murdoch et al. N Engl J Med. 286(15):804-8, 148). The musculoskeletal manifestations of MFS, which to date have received less attention, can also have a significant impact on the quality of life and are likely to become more important as the age of the Marfan syndrome population increases (Hasan et al. Int J Clin Pract. 61(8):1308-1320, 127). In addition, musculoskeletal manifestations are often critically important in the diagnosis of MFS. Here, we review the main clinically relevant and diagnostically useful musculoskeletal features of MFS, which together contribute to the "systemic features score" (referred to hereafter as systemic score), part of the revised Ghent nosology for MFS. We discuss current treatment strategies and highlight the need for a multidisciplinary approach to diagnosis and management. Finally, we review new pharmacological approaches that may be disease modifying and could help to improve the outcome for individuals with this syndrome.

Foot deformity in MFS. A Mild valgus hindfoot deformity of left foot (note alignment of heel to Achilles tendon and visible 5th toe). B Long slender feet with loss of medial foot arch (flatfeet) in another patient (right image)

A Axial CT scan demonstrating the focal protrusion of the chest wall seen in pectus carinatum (arrow). B Frontal view and C oblique view of patient with asymmetrical pectus excavatum

A CT reconstruction of thorax from individual with pectus excavatum. B The Haller index is calculated by dividing the transverse diameter of the chest by the anterior–posterior distance of the chest on an axial CT slice where the distance between the anterior surface of the vertebral body and the posterior surface of the sternum is the shortest. In this case, the index is 22/6 = 3.67 (severe pectus excavatum). Normal chest: < 2.0, mild excavatum: 2.0–3.2, moderate excavatum: 3.2–3.5, and severe excavatum: > 3.5

A Sagittal short tau inversion recovery (STIR) sequence demonstrating posterior vertebral body scalloping (arrowheads) and severe thinning of the sacrum (long arrow) due to dural ectasia. There is a wider dural sac at the level of S1 compared to L4. Note the kyphoscoliosis of the spine centred at L1–2. B Axial T2-weighted MRI demonstrates longstanding scalloping of the posterior aspect of the L5 vertebral body (arrows) due to dural ectasia

A Clinical appearance and B X-ray appearance of severe scoliosis in a patient with Marfan syndrome. Marked “double curvature” results in apparent clinical compensation although the length of the thorax (and therefore height) is markedly shortened as a result. This patient had relatively few symptoms despite deformity. Note X-ray reversed to mirror patient position, also evidence of previous sternotomy for cardiac surgery
