Ehlers-Danlos Syndrome in Athletes

Musculoskeletal Conditions in a Pediatric Population with Ehlers-Danlos Syndrome

OBJECTIVE

To describe musculoskeletal conditions in children with Ehlers-Danlos syndrome (EDS).

STUDY DESIGN

A retrospective medical record review was performed, which evaluated 205 patients with EDS (ages 6-19 years) seen in sports medicine or orthopedic clinic at a large pediatric hospital over a 5-year period.

RESULTS

Female (n = 147) and male (n = 57) patients were identified (mean age 12.7 years). The most common EDS subtype (55.6%) was hypermobility type. Patients had between 1 and 69 visits (median 4), and 764 diagnoses were recorded, most commonly laxity/instability, pain, subluxation, and scoliosis/spinal asymmetry. Nearly one-half of patients (46.8%) received a general diagnosis of pain because no more specific cause was identified, in addition to 8.3% who were diagnosed with chronic pain syndrome. The most common sites of presenting issue were knee (43.4%), back (32.2%), and shoulder (31.2%). Over three-fourths (77.1%) of patients had imaging. Most (88.1%) were prescribed physical therapy and/or other conservative measures, such as rest (40.5%), orthotics (35.6%), and medication (32.2%). Surgery was recommended to 28.8% of the study population.

CONCLUSIONS

Many pediatric and adolescent patients with EDS experience joint pain, instability, and scoliosis, along with other musculoskeletal issues. Despite extensive workup, the etiology of pain may not be identified. Large numbers of office visits, imaging studies, treatment prescriptions, and specialist referrals indicate considerable use of medical resources and highlight a great need for injury prevention and additional study.

Ehlers-danlos syndrome in orthopaedics: etiology, diagnosis, and treatment implications

Ehlers-Danlos syndrome is a heterogeneous connective tissue condition characterized by varying degrees of skin hyperextensibility, joint hypermobility, and vascular fragility. Joint dislocations, musculoskeletal pain, atrophic scars, easy bleeding, vessel/viscera rupture, severe scoliosis, and obstetric complications may occur. These manifestations are secondary to abnormal collagen, with specific molecular defects in types I, III, and V collagen; they may also be related to tenascin-X, which has been identified in some patients. Ehlers-Danlos syndrome has been classified into 6 types, with variable degrees of joint instability, skin hyperextensibility, wound healing difficulty, and vascular fragility. Diagnosis begins with recognition of the signs and symptoms of global hypermobility and referring appropriate patients for genetic consultation. It is important to accurately identify patients with Ehlers-Danlos syndrome 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.

[Sports purpura]

Recreational or regular physical and sport activities may be responsible for a wide range of cutaneous complications. Among them, "sports purpura" is a peculiar symptom that can occur during a large number of sports. "Effort purpura" defines any purpura occurring within the context of physical exercise irrespective of its cause. Therefore this clinical diagnosis includes various aetiologies. Diagnosis of traumatic purpura is often easy if the sport is mentioned in the anamnesis; cutaneous exercise - induced vasculitis must be also noted. Purpura can reveal systemic diseases or internal haemorrhage, such as spleen rupture, thrombopathies or systemic vasculitis, and other effort purpuras must be taken into account, including those related to the environment (cold, sun exposure...). Knowledge of a physical activity before the occurrence of purpura should be known by practitioner to avoid unnecessary and costly explorations in most of the cases.

Patellofemoral instability in athletes: treatment via modified Fulkerson osteotomy and lateral release

BACKGROUND

Surgical treatment of patellofemoral instability can successfully diminish episodes of subluxation and dislocation, as well as symptoms of pain and instability.

HYPOTHESIS

Surgical treatment of lateral patellar instability in a strictly athletic population will facilitate return to sports.

STUDY DESIGN

Case series; Level of evidence, 4.

METHODS

From 1999 to 2004, 41 Fulkerson osteotomies combined with an arthroscopic lateral release were performed in 34 athletes for patellofemoral instability. Three patients were lost to follow-up. All patients participated in sports at least 3 times per week in at least one sport for 4 months of the year. There were 4 male and 30 female patients; 7 patients underwent bilateral, staged procedures. There were 14 high school, 12 collegiate, and 8 recreational athletes. Results were obtained by an independent examiner.

RESULTS

The mean age was 20.05 years (range, 14-54 years) with a mean follow-up of 46 months (range, 22-71 months). Patients averaged 1.3 dislocations before reconstruction (range, 0-6). The average Lysholm score was 91.8 (range, 67-100) at follow-up. The International Knee Documentation Committee (IKDC) scores were A (normal) in 27 knees, B (near normal) in 12, and C (abnormal) in 2. Seventeen patients had symptomatic hardware removed at an average of 8 months. There were 2 complications: one saphenous neuroma that resolved, and one recurrent dislocation in a patient later diagnosed with Ehlers-Danlos syndrome.

CONCLUSION

This series is the largest to date documenting the successful treatment of patellofemoral instability in athletes with concomitant Fulkerson osteotomy and arthroscopic lateral release. Forty-nine percent of patients in our series required removal of screws from the osteotomy site.
