Marfan syndrome is an autosomal dominant disorder affecting mainly the skeletal, ocular and cardiovascular systems. Most cases are caused by mutations in the fibrillin-1 gene (FBN1), although there are some reports on deletions involving FBN1 and other additional genes. We report a male patient who was first evaluated at 4 years of age. Echocardiogram showed a mildly dilated aortic sinus. He also had a history of muscular ventral septal defect which was closed spontaneously and trivial mitral regurgitation...

BACKGROUND: The purpose of this work is to evaluate the results of arthroscopic capsulolabroplasty in patients affected by atraumatic shoulder instability (ASI). METHODS: A retrospective review was performed of 10 patients (7 women and 3 men) who underwent arthroscopic treatment of symptomatic ASI. Mean age at evaluation was 27.9 (19-35) years and the mean follow-up was 23.3 (12-37) months. We evaluated recurrence rate, range of movement, apprehension and relocation tests, hyperlaxity, and sport activity...

Marked ligamentous hyperlaxity and muscle weakness/wasting associated with awkward gait are the main deficits confused with the diagnosis of myopathy. Seven children (6 boys and 1 girl with an average age of 8 years) were referred to our department because of diverse forms of skeletal abnormalities. No definitive diagnosis was made, and all underwent a series of sophisticated investigations in other institutes in favor of myopathy. We applied our methodology through the clinical and radiographic phenotypes followed by targeted genotypic confirmation...

PURPOSE: Congenital muscular dystrophy (CMD) is a heterogeneous disease entity. The detailed clinical manifestation and causative gene for each subgroup of CMD are quite variable. This study aims to analyze the phenotypes and genotypes of Taiwanese patients with CMD as the epidemiology of CMD varies among populations and has been scantly described in Asia. METHODS: A total of 48 patients suspected to have CMD were screened and categorized by histochemistry and immunohistochemistry studies...

Arthroscopic hip capsular repair is an area of intense interest. Basic science studies suggest that adverse changes in capsular stability/restraint may occur with capsulotomy and capsulectomy, that repair may ameliorate these changes, and, most recently, that the repaired capsule usually heals. Clinical studies suggest that in some conditions, most notably mild dysplasia, capsular repair or plication may improve short-term outcomes, but in general, the role of capsular closure is less clear. At present, perhaps a selective approach is merited, with capsular closure performed in patients with dysplasia, focal or generalized hyperlaxity, and/or increased femoral anteversion...

Congenital myopathies define a heterogeneous group of neuromuscular diseases with neonatal or childhood hypotonia and muscle weakness. The genetic cause is still unknown in many patients, precluding genetic counselling and better understanding of the physiopathology. To identify novel genetic causes of congenital myopathies, exome sequencing was performed in three consanguineous families. We identified two homozygous frameshift mutations and a homozygous nonsense mutation in the mitogen-activated protein triple kinase ZAK...

BACKGROUND: Although recurrent anterior shoulder instability (RASI) is a common condition in young patients, no studies to date have measured the 3-dimensional (3D) locked position of the glenohumeral joint during an anterior dislocation. Therefore, our goal was to estimate it with 3D computed tomography (CT) scans. METHODS: Patients in this prospective observational study were separated in 3 groups: normal laxity, hyperlaxity, and epilepsy. They were characterized by questionnaires (Western Ontario Shoulder Instability Index, 11-item version of the Disabilities of the Arm, Shoulder and Hand, and Beighton Laxity Score), and a CT scan revealing bipolar bone defects...

OBJECTIVE: The isokinetic exploration of the shoulder seems little standardized, particularly at the time of the choice of the studied muscular groups, of the installation of the subject as well as positioning of the articulation itself. OBSERVATIONS: Rehabilitation treatment of a 17 year old patient, hyperlaxe, swimmer, in the context of a painful chronic former instability of the shoulder without osseous, muscular lesion or labrale. An isokinetic work of reinforcement of the internal rotators is carried out, into concentric of 60°/s to 240°/s, position known as of Davies modified then in decubitus dorsal of 45° to 90° of abduction...

Swimmer's shoulder is a broad term often used to diagnose shoulder injury in swimmers. However, research has elucidated several specific shoulder injuries that often are incurred by the competitive swimmer. Hyperlaxity, scapular dyskinesis, subacromial impingement, labral damage, os acromiale, suprascapular nerve entrapment, and glenohumeral rotational imbalances all may be included within a differential diagnosis for shoulder pain in the competitive swimmer. An understanding of the mechanics of the swim stroke, in combination with the complex static and dynamic properties of the shoulder, is essential to the comprehension and identification of the painful swimmer's shoulder...

Despite recent progress in the genetic characterization of congenital muscle diseases, the genes responsible for a significant proportion of cases remain unknown. We analysed two branches of a large consanguineous family in which four patients presented with a severe new phenotype, clinically marked by neonatal-onset muscle weakness predominantly involving axial muscles, life-threatening respiratory failure, skin abnormalities and joint hyperlaxity without contractures. Muscle biopsies showed the unreported association of multi-minicores, caps and dystrophic lesions...

Cutis laxa (CL) syndromes are connective tissue disorders characterized by redundant, sagging, inelastic and wrinkled skin, with organ involvement. Here, we describe a patient with ALDH18A1-related CL who developed cyclic vomiting. The patient was a 12-year-old boy who presented with poor postnatal growth, hypotonia, short stature, joint hyperlaxity, microcephaly, strabismus, bilateral cataracts, facial dysmorphism and severe mental retardation. Bone radiographs showed osteopenia and osteoporosis, and magnetic resonance angiography showed marked kinking and tortuosity of the brain vessels...

INTRODUCTION: Multiminicore disease is a congenital myopathy characterized pathologically by the presence of multiple minicore structures in the sarcoplasm. Mutations in the selenoprotein N1-encoding gene (SEPN1) and ryanodine receptor 1-encoding gene (RYR1) are responsible for half of the reported cases. Mutations in multiple epidermal growth factor-like domains 10-encoding gene (MEGF10) have been identified only recently in a few patients with antenatal to infantile-onset myopathy, with and without minicore pathology...

INTRODUCTION: Traditionally surgeons have treated failed shoulder instability with open capsulolabral repair. Despite improved instrumentation, technique and familiarity in shoulder arthroscopy, few studies have reported the outcomes of arthroscopic revision shoulder instability repair. The purpose of this study was to assess clinical outcomes in patients following revision shoulder arthroscopic anterior capsulolabral stabilization. MATERIALS AND METHODS: Sixty-two patients (63 shoulders) with failure of primary instability repairs were treated with revision arthroscopic anterior shoulder stabilization at a mean follow-up of 46...

BACKGROUND: Excessive physiological anterior and rotational knee laxity is thought to be a risk factor for noncontact anterior cruciate ligament (ACL) injuries and inferior reconstruction outcomes, but no thresholds have been established to identify patients with increased laxity. PURPOSE: (1) To determine if the healthy contralateral knees of ACL-injured patients have greater anterior and rotational knee laxity, leading to different laxity profiles (combination of laxities), compared with healthy control knees and (2) to set a threshold to help discriminate anterior and rotational knee laxity between these groups...
