  • The Ehlers–Danlos Syndromes
    PRIMER The Ehlers–Danlos syndromes Fransiska Malfait1 ✉ , Marco Castori2, Clair A. Francomano3, Cecilia Giunta4, Tomoki Kosho5 and Peter H. Byers6 Abstract | The Ehlers–Danlos syndromes (EDS) are a heterogeneous group of hereditary disorders of connective tissue, with common features including joint hypermobility, soft and hyperextensible skin, abnormal wound healing and easy bruising. Fourteen different types of EDS are recognized, of which the molecular cause is known for 13 types. These types are caused by variants in 20 different genes, the majority of which encode the fibrillar collagen types I, III and V, modifying or processing enzymes for those proteins, and enzymes that can modify glycosaminoglycan chains of proteoglycans. For the hypermobile type of EDS, the molecular underpinnings remain unknown. As connective tissue is ubiquitously distributed throughout the body, manifestations of the different types of EDS are present, to varying degrees, in virtually every organ system. This can make these disorders particularly challenging to diagnose and manage. Management consists of a care team responsible for surveillance of major and organ-specific complications (for example, arterial aneurysm and dissection), integrated physical medicine and rehabilitation. No specific medical or genetic therapies are available for any type of EDS. The Ehlers–Danlos syndromes (EDS) comprise a genet­ six EDS types, denominated by a descriptive name6.

  • Spondylolisthesis, with Description of a Case
    [Reprinted from the Transactions of the American Orthopedic Association, 1897.] SPONDYLOLISTHESIS, WITH DESCRIPTION OP A CASE. ROBERT W. LOVETT, M.D., BOSTON. The name spondylolisthesis (ottovoo/loc, a vertebra, and bhadrjat c, a gliding) refers to a forward subluxation of the body of one of the lower lumbar vertebrae, with the exception of one recorded case where the upper part of the sacrum was displaced forward. This displacement has ordinarily been described as a dislocation ; in most instances it hardly reaches a greater degree than may be described by the name subluxation. Even this name is incorrect anatomic- ally. This is because the body of the vertebra is chiefly affected, while the laminae and spinous process remain practically in place. The condition has attracted attention chiefly from the obstetrical point of view, on account of the secondary pelvic changes produced, and surgical literature contains next to nothing about it. Fr. Neugebauer, 1 of Warsaw, has so thoroughly investigated and elab- orated the subject that whoever strives to elucidate it from any point of view must do so largely by quotations from his extensive writings. In 1854, when this condition was recognized and named by Killian, 2 there were described only four known anatomical speci- mens. In 1890, when Neugebauer’s treatise was written, there were one hundred and one clinical and anatomical observations. Blake, 3 Gibuey, 4 and Lombard 5 contributed the only recorded American observations. Between the publication of Neugebauer’s classic in 1892, which was written in 1890, and to-day there have been reported, so far as I could find, twenty-four more cases (two in men).

  • The Impact of Hypermobility Spectrum Disorders on Musculoskeletal Tissue Stiffness: an Exploration Using Strain Elastography

HSD’s diagnostic approach is highly subjective, its validity is not well studied, and it does not consider many of the most commonly affected joints. Strain elastography (SEL) reflects musculoskeletal elasticity with sonographic images. The study explored the impact of HSD on musculoskeletal elasticity using SEL. A cross-sectional design compared 21 participants with HSD against 22 controls. SEL was used to assess the elasticity of the deltoid, biceps brachii, brachioradialis, rectus femoris, and gastrocnemius muscles, and the patellar and Achilles tendon. SEL images were analyzed using strain index, strain ratio, and color pixels. Mean strain index (standard deviation) was significantly reduced in the HSD group compared to the control group in the brachioradialis muscle 0.43 (0.10) vs. 0.59 (0.24), patellar 0.30 (0.10) vs. 0.44 (0.11), and Achilles tendons 0.24 (0.06) vs. 0.49 (0.13). Brachioradialis muscle and patellar tendon’s strain ratios were significantly lower in the HSD group compared to the control group, 6.02 (2.11) vs. 8.68 (2.67) and 5.18 (1.67) vs.

  • The Orthopaedic Management of Arthrogryposis Multiplex Congenita
    Current Concept Review The Orthopaedic Management of Arthrogryposis Multiplex Congenita Harold J. P. van Bosse, MD and Dan A. Zlotolow, MD Shriners Hospital for Children, Philadelphia, PA Abstract: Arthrogryposis multiplex congenita (AMC) describes a baby born with multiple joint contractures that results from fetal akinesia with at least 400 different causes. The most common forms of AMC are amyoplasia (classic ar- throgryposis) and the distal arthrogryposes. Over the past two decades, the orthopaedic treatment of children with AMC has evolved with a better appreciation of the natural history. Most adults with arthrogryposis are ambulatory, but less than half are fully independent in self-care and most are limited by upper extremity dysfunction. Chronic and epi- sodic pain in adulthood—particularly of the foot and back—is frequent, limiting both ambulation and standing. To improve upon the natural history, upper extremity treatments have advanced to improve elbow motion and wrist and thumb positioning. Attempts to improve the ambulatory ability and decrease future pain include correction of hip and knee contractures and emphasizing casting treatments of foot deformities. Pediatric patients with arthrogryposis re- quire a careful evaluation, with both a physical examination and an assessment of needs to direct their treatment. Fur- ther outcomes studies are needed to continue to refine procedures and define the appropriate candidates. Key Concepts: • Arthrogryposis multiplex congenita (AMC) is a term that describes a baby born with multiple joint contractures. Amyoplasia is the most common form of AMC, accounting for one-third to one-half of all cases, with the distal arthrogryposes as the second largest AMC type.

As such some confusion arose over the use of JHS/EDS-HM co-terminology. 4 The 2017 international criteria for the Hypermobile variant of EDS (hEDS) were developed to address this, give clarity as to the diagnosis of hEDS, and also allow opportunity for more focused basic science and clinical research including assessment of treatment outcomes. 5 The term JHS has been dropped. Those individuals with hypermobility-related problems that do not have hEDS; or any other Heritable Disorder of Connective Tissue; or other syndromic or secondary myopathic, neuropathic, or traumatic cause for hypermobility / joint instability are now given the diagnosis of Hypermobility Spectrum Disorder (HSD). 6 There is a ‘spectrum’ of presentations laying between asymptomatic hypermobility and the diagnosis of hEDS. This does not infer any greater severity at one end of the spectrum compared to the other.
