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 present as an asymptomatic finding or as a component of heritable connective tissue disorders, most notably Ehlers-Danlos syndrome [1]. The hypermobile type of Ehlers-Danlos syndrome (hEDS) is likely the most common hereditary disorder of connective tissue [6]. Despite its prevalence, the clinical significance of joint hypermobility remains under-appreciated, and its impact is largely ignored in rheumatology [9]. 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 [4]. Every effort should be made to diagnose the underlying disorder responsible for joint hypermobility, which may only become apparent over time [2].
Accurate identification of 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 [5]. The natural history of hypermobility type Ehlers-Danlos syndrome (HT-EDS) is delineated into three phases: hypermobility, pain, and stiffness [13]. Addressing underlying hypermobility as well as the treatment of individual joints is important in the treatment of hypermobile Ehlers-Danlos syndrome [10]. Exploring the patient's articular features in her clinical context led to a diagnosis of joint hypermobility syndrome, a complex and often ignored condition [8].
Greater emphasis should be placed on a clinician's judgement to identify or exclude generalised joint hypermobility, according to its full definition [12]. 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 [7]. The prevalence of joint hypermobility in dancers ranges from 2-44% depending on criteria, with higher rates in students than professionals [16]. Abnormalities in the hand and wrist joint that are directly related to joint hypermobility are discussed in four patients with Ehlers-Danlos syndrome [3].
Background & Causes¶
Orthopaedic surgeons must recognize the implications of joint mobility syndromes in the management and rehabilitation of several musculoskeletal injuries and orthopaedic disorders [15]. Joint laxity explains why certain individuals are more prone to sustain capsulo-ligamentous injuries than others [28]. In pediatric populations, the prevalence of hypermobility was three times higher in children with anxiety disorders, and only age was a predictor for the possibility to suffer from generalized joint hypermobility in these children [25]. Sensory processing functions are unlikely to contribute to the common complaints reported by hypermobile individuals [21].
Hand and Upper Extremity Manifestations Patients with Ehlers-Danlos syndrome demonstrated numerous clinical and radiographic abnormalities of their hands, including increased range of motion of all finger joints and weakness of pinch and grip [14]. The carpometacarpal joint of the thumb may be particularly susceptible to weakened ligamentous constraints in Ehlers-Danlos syndrome [20]. Dynamic swan neck deformity in a patient with Ehlers-Danlos syndrome resulted from primary ligamentous laxity due to the underlying disease, type I EDS [18].
Lower Extremity and Bone Pathology A higher degree of joint hypermobility was also correlated with more severe hip dysplasia [23]. The observation of acroosteolysis in a patient with Ehlers-Danlos Syndrome, in the absence of any associated factors or Raynaud's phenomenon, raises the possibility of a connection between the abnormality of collagen inherent in Ehlers-Danlos Syndrome and the mechanism of this obscure localised bone resorption [22].
Symptoms & Presentation¶
Patients with Ehlers-Danlos syndrome (EDS) frequently present with musculoskeletal complaints, primarily joint pain and instability [24]. A thorough history and physical examination are essential to identify the constellation of musculoskeletal conditions associated with generalized joint laxity [17]. In the context of joint hypermobility syndrome, associated symptoms may include arthralgias, fatigue, paresthesias, and visceral pain [8].
Hand and Wrist Pathology: Abnormalities in the hand and wrist joints directly related to joint hypermobility are characteristic of EDS [3]. These patients demonstrate increased range of motion of all finger joints [14]. Concurrently, weakness of pinch and grip is a documented finding [14]. Dynamic swan neck deformity in EDS results from primary ligamentous laxity inherent to the underlying disease [18]. Acroosteolysis has been observed in EDS patients in the absence of associated factors or Raynaud's phenomenon [22]. This observation suggests a potential connection between the collagen abnormality inherent in the syndrome and the mechanism of localised bone resorption [22].
Pediatric and Psychiatric Associations: The prevalence of hypermobility is three times higher in children with anxiety disorders [25]. In this specific pediatric population, only age serves as a predictor for the possibility of suffering from generalized joint hypermobility [25].
Occupational and Surgical Correlates: Prevalence rates of joint hypermobility in dancers range from 2-44% depending on the criteria used [16]. Higher rates of joint hypermobility are observed in dance students compared to professionals [16]. In patients undergoing periacetabular osteotomy, a higher degree of joint hypermobility correlates with more severe hip dysplasia [23].
Imaging Implications: Subtle findings on radiographs or MRI can significantly impact decision-making in patients with generalized joint laxity [17].
Management¶
Diagnosis and Assessment¶
Exploring a patient's articular features within their clinical context can lead to a diagnosis of joint hypermobility syndrome, a complex and often ignored condition [8]. Careful history and examination may reveal a constellation of musculoskeletal conditions associated with generalized joint laxity, while subtle findings on radiographs or MRI can impact decision-making [17]. Patients with EDS often seek treatment for musculoskeletal symptoms of joint pain and instability, making the hand or orthopedic surgeon the first to encounter and potentially diagnose this condition [24].
Clinical Implications and Natural History¶
EDS-HT is characterised by various severe musculoskeletal complaints and has a detrimental effect on the habitual level of physical activity and health-related quality of life, in both physical and psychosocial dimension [27].
Musculoskeletal Findings¶
Abnormalities in the hand and wrist joint that are directly related to joint hypermobility are present in patients with Ehlers-Danlos syndrome [3]. Patients with Ehlers-Danlos syndrome demonstrate numerous clinical and radiographic abnormalities of their hands, including increased range of motion of all finger joints and weakness of pinch and grip [14].
Treatment Principles¶
Addressing underlying hypermobility as well as the treatment of individual joints is important in the treatment of hypermobility syndrome [10]. Bilateral arthroscopic tendon interposition arthroplasty of the thumb carpometacarpal joint has been reported as a treatment for osteoarthritic thumb basal joints in patients with Ehlers-Danlos syndrome [26]. Given the heterogeneity of clinical outcomes in anterior cruciate ligament reconstruction, future studies should clarify whether greater residual laxity represents a clinically relevant disadvantage or whether it can be well tolerated without a meaningful impact on patient-reported and functional outcomes [19].

Given the heterogeneity of clinical outcomes, future studies should clarify whether the greater residual laxity represents a clinically relevant disadvantage or whether it can be well tolerated without a meaningful impact on patient-reported and functional outcomes [19].
