Joint Hypermobility and Ehlers-Danlos Syndrome
Joint hypermobility and EDS — instability and surgical implications (corpus-synthesised).
For patients: a plain-language version of this topic is available. See the patient guide.
Overview¶
Joint hypermobility is a multifactorial condition that may be asymptomatic or part of a heritable disorder of connective tissue such as Ehlers-Danlos syndrome [1]. The hypermobile type of Ehlers-Danlos syndrome (hEDS) is likely the most common hereditary disorder of connective tissue [5], and joint hypermobility is a common disorder whose significance is under-appreciated and impact largely ignored in rheumatology [7]. Every effort should be made to diagnose the underlying disorder responsible for joint hypermobility, which may only become apparent over time [2], as a number of heritable disorders of connective tissue are associated with joint hypermobility and should be considered when assessing patients with hypermobility due to wider implications for the patient [3].
Accurate identification of patients with Ehlers-Danlos syndrome is required to initiate appropriate musculoskeletal treatment, optimize anesthetic and postoperative management, perform appropriate vascular screening, and help families address concerns with advocacy groups [4]. Greater emphasis should be placed on a clinician's judgement to identify or exclude generalised joint hypermobility according to its full definition [8], though future research on the validity of the tests and criteria for joint hypermobility is urgently needed [11]. A simplified categorization of genetic syndromes featuring joint hypermobility has been proposed, introducing the concept of a spectrum of pathogenetically related manifestations [6]. Prevalence rates of joint hypermobility in dancers range from 2-44% depending on criteria, with higher rates observed in students than professionals [13].

Greater emphasis should be placed on a clinician's judgement to identify or exclude generalised joint hypermobility according to its full definition [8]. Exploring a patient's articular features in their clinical context can lead to a diagnosis of joint hypermobility syndrome, a complex and often ignored condition [9].
The natural history of hypermobility type Ehlers-Danlos syndrome (HT-EDS) is delineated into three phases: hypermobility, pain, and stiffness [10]. Joint hypermobility is a common disorder whose significance is under-appreciated and impact largely ignored in rheumatology [7]. Sensory processing functions such as somatognosia and stereognosia are unlikely to contribute to the common complaints reported by hypermobile individuals [14].

Management¶
Joint hypermobility is a multifactorial condition that may be asymptomatic or part of a heritable disorder of connective tissue such as Ehlers-Danlos syndrome [1]. Every effort should be made to diagnose the underlying disorder responsible for joint hypermobility, which may only become apparent over time [2]. A number of heritable disorders of connective tissue are associated with joint hypermobility and should be considered when assessing patients, as they can have wider implications for the patient [3]. Orthopaedic surgeons must recognize the implications of joint mobility syndromes in the management and rehabilitation of several musculoskeletal injuries and orthopaedic disorders [12].
Diagnostic Priorities: Accurate identification of patients with Ehlers-Danlos syndrome is critical to initiate appropriate musculoskeletal treatment, optimize anesthetic and postoperative management, perform appropriate vascular screening, and help families address their concerns with other families and advocacy groups [4]. Greater emphasis should be placed on a clinician's judgement to identify or exclude generalised joint hypermobility, according to its full definition [8]. Exploring the patient's articular features in her clinical context led to a diagnosis of joint hypermobility syndrome, a complex and often ignored condition [9].
Epidemiology and Classification: The hypermobile type of Ehlers-Danlos syndrome (hEDS) is likely the most common hereditary disorder of connective tissue [5]. A simplified categorization of genetic syndromes featuring joint hypermobility introduces the concept of a spectrum of pathogenetically related manifestations [6]. Joint hypermobility is a common disorder whose significance is under-appreciated and impact largely ignored in rheumatology [7].

Future research on the validity of the tests and criteria for joint hypermobility is urgently needed due to issues with inter-examiner reproducibility [11].
