Foetal movements commence at seven weeks of gestation, with the foetal movement repertoire including twitches, whole body movements, stretches, isolated limb movements, breathing movements, head and neck movements, jaw movements (including yawning, sucking and swallowing) and hiccups by ten weeks of gestational age. There are two key biomechanical aspects to gross foetal movements; the first being that the foetus moves in a dynamically changing constrained physical environment in which the freedom to move becomes increasingly restricted with increasing foetal size and decreasing amniotic fluid...

Spinal muscular atrophy is a disorder of lower motor neurons, most commonly caused by recessive mutations in SMN1 on chromosome 5q. Cases without SMN1 mutations are subclassified according to phenotype. Spinal muscular atrophy, lower extremity-predominant, is characterized by lower limb muscle weakness and wasting, associated with reduced numbers of lumbar motor neurons and is caused by mutations in DYNC1H1, which encodes a microtubule motor protein in the dynein-dynactin complex and one of its cargo adaptors, BICD2...

OBJECTIVE: Accurate understanding of the cause of the underlying pathology in children with diastrophic dysplasia would help in designing targeted management of their locomotion. METHODS: Diastrophic dysplasia was diagnosed in twelve patients (nine girls and three boys; age range 1-14 years), all of whom presented with small stature and apparent short extremities. Club foot (mostly talipes equinovarus) was the most frequent and consistent abnormality. Concomitant abnormalities such as hip flexion contracture, flexion contractures of the knees with excessive valgus deformity and lateral patellar subluxation, were also encountered...

BACKGROUND: Arthrogryposis multiplex congenita (AMC) is a multiple joint condition which affects both lower and upper extremities and thus affects ambulation. Multiple surgeries are needed to correct limb deformity in order to promote walking. The objective of this study is to identify the most critical residual deformity that diminishes the ambulatory status. MATERIALS AND METHODS: 51 patients were included in this study, 14 patients were nonambulatory. The mean age at first surgery was 4...

Distal arthrogryposis syndromes (DAs) show wide clinical variability and overlapping clinical findings with the other DAs classified by Bamshad et al. [1996]. Most of the DAs are inherited as autosomal dominant disorders. DA type 5D is a subtype of DA type 5 inherited as autosomal recessive disorder, clinically characterized by congenital distal joint contractures, knee extension contractures, congenital hip dislocation, club foot, ptosis and other eye findings, furrowed tongue, and scoliosis. Here, we report on a family with clinical features of DA type 5D with novel mutations in the ECEL1 gene...

REVIEW
Kimberly A Fisher, David A Fisher
Arthrogryposis multiplex congenita (AMC) is a complex disorder that leads to joint stiffness and deformities in 2 or more joints in afflicted children. Late manifestations of this disorder can include secondary degeneration of the abnormal joints with arthritic symptoms of pain and loss of function. There are few reports in the orthopedic literature on the use of total joint arthroplasty to improve the pain and function in patients with arthrogryposis. This case report presents one patient who underwent bilateral total hip and total knee arthroplasties for deteriorating function and pain in her hips and knees secondary to the congenital deformities created by arthrogryposis multiplex congenita...

Nonlethal Escobar is a rare disorder that is a variant of multiple pterygium syndromes. It is a form of arthrogryposis multiplex congenita characterized by excessive webbing (pterygia), congenital contractures (arthrogryposis), and scoliosis. It is usually diagnosed in utero on fetal ultrasound and then confirmed in the neonatal period. A case of nonlethal neonatal Escobar is reported in a 35-week-and-6-day old infant who presented in utero with decreased fetal movement, oligohydramnios, and arthrogryposis...

Ipsilateral trunk lean toward the affected stance limb has been identified as a compensatory mechanism to unload the hip joint. However, this altered gait pattern increases the lever arm around the knee joint by shifting the ground reaction vector more lateral to the knee joint center, which could be sufficient to deform the lateral compartment of the knee. The purpose of the present study was to show the effect of ipsilateral trunk lean on hip and knee joint moments in the frontal plane in 132 young patients with different orthopedic diagnosis...

INTRODUCTION: Studies of gait dynamics revealed the complex motions that the knee must undergo in sync with the hip and ankle, in both the swing and support phase of walking. If these motions are restricted, usually as a consequence of cerebral palsy or arthrogryposis, normal gait is hindered; the patient may be able to walk for very short distances or, eventually, not at all. Children with knee extension limited by 10 - 30 degrees,especially those with cerebral palsy, exhibit a stance compatible with walking...

BACKGROUND: Arthrogryposis multiplex congenita is an etiopathogenetically heterogeneous disorder characterised by non-progressive multiple intra-articular contractures, which can be recognised at birth. The frequency is estimated at 1 in 3,000 newborns. Etiopathogenesis of arthrogryposis is multifactorial. CASE PRESENTATION: We report first 26 weeks of life of a boy with severe arthrogryposis. Owing to the integrated rehabilitation approach and orthopaedic treatment a visible improvement in the range of motion as well as the functionality of the child was achieved...

The aim was to investigate the causes for pathological trunk movements during gait in children with Amyoplasia. Eighteen children with Amyoplasia were compared with 18 typically developed children. Three-dimensional motions of pelvis, thorax and spine during gait were analyzed. Excessive trunk movements were defined as being above 4 standard deviations of those of typically developed children. Clinical examination of active strength and passive range of motion of the hip, knee and ankle joints were correlated to the parameter that showed the greatest prevalence of pathological trunk motion...

Among 2,500 cases of arthrogryposis, 14 families and 17 individuals were identified that had a linear vertical crease (indentation/dimple) along the anterior tibia, usually bilaterally. Approximately half had developmental delay/intellectual disability and the others had normal intellectual development. There are generalized flexion contractures with the legs more severely affected than the arms. The ankles are flexed at birth suggesting a relationship of contraction of the anterior tibial compartment to the in utero development of the anterior tibial crease...

Congenital knee dislocation is a rare anomaly associated with a variety of neuromuscular diseases and deformities. The etiology of this condition remains unclear, but it is usually associated with a variety of disorders, such as Larsen's syndrome, arthrogryposis, spondyloepiphyseal dysplasia, Ehlers-Danlos syndrome, Down syndrome, and Streeter's dysplasia. It is rarely an isolated entity, and 60% of patients with congenital knee dislocation had additional congenital anomalies, most commonly hip dysplasia. The ideal method of treatment is debated...

We reviewed our clinical and radiographic results in the operative treatment of five unilateral and six bilateral hip dislocations in 11 patients with amyoplasia-type arthrogryposis. The mean age at surgery was 1.8 (range, 1.1-3.2) years. Femoral and/or pelvic osteotomies were combined with an open reduction. The mean follow-up period was 12.7 (range, 5.2-23.2) years. Nine patients were community walkers and two were household walkers. The range of motion and the St Clair hip score of the bilateral hips were not significantly different from those of the unilateral hips...

PURPOSE: Congenital dislocation of the knee (CDK) is a relatively rare condition. It may occur as an isolated deformity, it may be associated with musculoskeletal anomalies such as developmental dysplasia of the hip and clubfoot, or it may occur as part of a syndrome such as arthrogryposis multiplex congenita or Larsen syndrome, or it may occur in paralytic conditions such as meningomyelocele. Treatment options include serial casting, percutaneous quadriceps recession (PQR) and V-Y quadricepsplasty (VYQ)...

Arthrogryposis represents a group of heterogeneous disorders, characterized by contractures of multiple joints at birth. Involvement of the hip is very common (55-90% of patients) ranging from soft tissue contractures to subluxation and dislocation. Isolated contracture of the hip can usually be managed conservatively: compensative mechanisms and contractures of other joints should be evaluated before planning surgery. For unilateral dislocations, open reduction is indicated to provide a level pelvis, even though the risk of stiffness, avascular necrosis and redislocation is significant...

Heel wedges may influence standing posture but how and to what extent are unknown. Thirty-two children with motor disorders - 16 with arthrogryposis multiplex congenita (AMC) and 16 with cerebral palsy (CP) - and 19 control children underwent a three-dimensional motion analysis. Unassisted standing during 20s with shoes only and with heel lifts of 10, 20 and 30mm heights was recorded in a randomized order. The more weight-bearing limb or the right limb was chosen for analysis. In both the AMC and CP groups, significant changes were seen between various heel lifts in ankle, knee and pelvis, and in the control group in the ankle only...

PURPOSE: Lower limb contractures and muscle weakness are common in children with arthrogryposis multiplex congenita (AMC). To enhance or facilitate ambulation, orthoses may be used. The aim of this study was to describe gait pattern among individuals wearing their habitual orthotic devices. METHODS: Fifteen children with AMC, mean age 12.4 (4.3) years, with some lower limb involvement underwent 3-D gait analysis. Three groups were defined based on orthosis use; Group 1 used knee-ankle-foot orthoses with locked knee joints, Group 2 used ankle-foot orthoses or knee-ankle-foot orthoses with open knee joints and Group 3 used no orthoses...
