Introduction

Congenital dislocation hip

There are a large number of different musculoskeletal abnormalities affecting one or a combination of bone and muscle development in the skull, trunk and limbs. This page therefore can only broadly introduce the topic and link to other resources with more specific information.

Musculoskeletal and limb disorders together form the largest group of congenital defects that occur in Australia. The three most commonly occurring are developmental dysplasia of the hip, cleft palate, cleft lip and palate.

Some defects appear as obvious malformations, such as syndactyly and limb reductions. Other muscular defects only become obvious postnatally when the muscles are required to be used, those in highest use are respiratory (diaphragm, intercostals) and anti-gravity (those that hold you upright) muscles.

Some Recent Findings

  • Mutations in INPP5K cause a form of congenital muscular dystrophy overlapping Marinesco-Sjögren syndrome and dystroglycanopathy [1] "Congenital muscular dystrophies display a wide phenotypic and genetic heterogeneity. The combination of clinical, biochemical, and molecular genetic findings must be considered to obtain the precise diagnosis and provide appropriate genetic counselling. Here we report five individuals from four families presenting with variable clinical features including muscular dystrophy with a reduction in dystroglycan glycosylation, short stature, intellectual disability, and cataracts, overlapping both the dystroglycanopathies and Marinesco-Sjögren syndrome. Whole-exome sequencing revealed homozygous missense and compound heterozygous mutations in INPP5K in the affected members of each family. INPP5K encodes the inositol polyphosphate-5-phosphatase K, also known as SKIP (skeletal muscle and kidney enriched inositol phosphatase), which is highly expressed in the brain and muscle."
  • The incidence of common orthopaedic problems in newborn at Siriraj Hospital[2] "A prospective study was conducted by physical examination of 3,396 newborns from June 2009 to September 2009. Incidence of calcaneovalgus was found in 60:1,000 live births following by metatarsus adductus in 7.6:1,000, polydactyly or syndactyly in 2.6:1,000, talipes equninovarus in 2.4:1,000, brachial plexus injury in 1.5:1,000, developmental dysplasia of hip in 0.6:1,000, osteogenesis imperfecta in 0.6:1,000, skeketal dysplasia in 0.6:1,000, congenital vertical talus in 0.3: 1,000 and fracture clavicle at birth in 0.3: 1,000. In the present study, the calcaneovalgus (flexible flatfoot) was the most common orthopaedic problem followed by metatasus adductus, polydactyly or syndactyly."
  • Delayed bone age due to a dual effect of FGFR3 mutation in Achondroplasia.[3] "All these data provide evidence that FGFR3 regulates normal chondrocyte proliferation and differentiation during bone growth and suggest that constitutive activation of the receptor disrupts both processes. Therefore, the consequences of FGFR3 activation on the physiological process of bone development appear to be dependent on spatial and temporal occurrence."

Developmental Dysplasia of the Hip

X-Ray Developmental Dysplasia of the Hip
Acetabular angle[4]

Also called Congenital Hip Dislocation.

  • Instability: 1:60 at birth; 1:240 at 1 wk: Dislocation untreated; 1:700
  • congenital instability of hip, later dislocates by muscle pulls or gravity
  • familial predisposition female predominance
  • Growth of femoral head, acetabulum and innominate bone are delayed until the femoral head fits firmly into the acetabulum.

Barlow test

(Barlow maneuver) A clinical term to describe a physical examination of the newborn for developmental dysplasia of the hip (DDH). The examiner adducts the hip (bringing the thigh towards the midline) while applying light pressure on the knee, directing the force posteriorly. A positive sign is the hip being dislocatable, if the hip can be popped out of socket with this test. This test is then combined with the Ortolani test (maneuver). The test is named after Thomas Barlow (1845 – 1945) a British royal physician.

Ortolani test

Ortolani maneuver) A clinical term to describe a physical examination of the newborn for developmental dysplasia of the hip (DDH). This is a test for posterior dislocation of the hip. Using the examiner's thumb, abduct the infant's leg, while using the examiner's index finger to place anterior pressure on the greater trochanter. A positive sign is a distinctive 'clunk' which can be heard and felt as the femoral head relocates anteriorly into the acetabulum, usually becomes negative after 2 months of age. This test is combined with the Barlow test (maneuver). Named after Marino Ortolani, the test developer in 1976.

Abduction Splints

There is variable evidence for the use of abduction splinting during onset of walking in children on the maturation of mild dysplastic hips.[4]

  • frequency of congenital scoliosis is approximately 0.5, or 1 in 1,000 births.
  • assymetric growth impairment of vertebral bodies
  • lateral deviation of spine (Lateral flexion, Forward flexion, Rotation of vertebral column on long axis)
  • compensated by movement of vertebral column above and below affected region (producing a primary and two secondary curves)
  • progresses rapidly in adolescence and becomes fixed once bone growth is completed.
  • both genetic and environmental terartogens implicated.
    • a large number of chromosomal deletions relating to regions 2p13 – 15, 6q13 and 15q12 have been identified.

Chêneau's Brace

Chêneau Brace[6]

Dr. Chêneau fabricated the original "Chêneau Brace" in 1979 and is commonly used for the treatment of scoliosis and thoracic hypokyphosis in some European countries, though not commonly in either North America or the United Kingdom. The brace corrects by a system of multipoint pressure zones and expansion chambers.

Harrington Rod

Dr Paul Harrington, a USA orthopaedic surgeon, in 1953 designed the "Harrington implant", the first modern spinal instrumentation system that produced both correction and immobilization. This historic system has now been replaced by more modern systems.

Muscle Development

There can be abnormalities associated directly with muscle differentiation and function as well as those mediated indirectly by abnormalities of innervation or skeletal development and other associated systems.

Duchenne Muscular Dystrophy

The most common occuring in Boys and in Duchenne Muscular Dystrophy (DMD). This cause of the disease was discovered in 1988 as a mutation in dystrophin, a protein that lies under the muscle fiber membrane and maintains the cell's integrity. As skeletal muscles have little prenatal load or use it is not until postnatally that muscle wasting occurs, usually in the anti-gravity muscles first. This is a progressive disease usually detected between 3-5 years old.

  • X-linked dystrophy
  • large gene encoding cytoskeletal protein - Dystrophin
  • progressive wasting of muscle, die late teens

Becker Muscular Dystrophy

A milder adult (30-40 years old) onset form of the disease Becker's Muscular Dystrophy (BMD) that involves mutations in the same dystrophin gene.

Autosomal Recessive Muscular Dystrophy

Dystroglycan, a protein that associates with both dystrophin and membrane molecules, is a candidate gene for the site of the mutation in autosomal recessive muscular dystrophies. A knockout mouse has been generated that has early developmental abnormalities.

Myotonic Dystrophy

An inherited disorder in which the muscles contract but have decreasing power to relax. With this condition, the muscles also become weak and waste away. The myotonic dystrophy gene, found on chromosome 19, codes for a protein kinase that is found in skeletal muscle, where it likely plays a regulatory role. The disease is "amplified" through generations probably by a similar GC expansion associated with Huntington disease.

Facioscapulohumeral Muscular Dystrophy

(FSHD) This form of muscular dystrophy is an autosomal dominant genetic disorder characterized by progressive muscle weakness and wasting that typically begins in the face, shoulder-girdle and upper arm. Currently thought to relate to an impaired muscle regeneration process.

Limb Abnormalities

Genetic

  • Human Gene Mutations - mutation of any of the patterning genes will result in limb abnormalities (Will put Table on Web page mutations and terminology)

Type II syndactyly- HoxD13

Maternal

  • thalidomide Phocomelia
  • short ill-formed upper or lower limbs
  • hyperthermia

Syndactyly

Syndactyly

Fusion of fingers or toes which may be single or multiple and may affect: skin only, skin and soft tissues or skin, soft tissues and bone.

The condition is unimportant in toes but disabling in fingers and requires operative separation and is frequently inherited as an autosomal dominant.

The presence of this additional "webbing" reflects preservation of the developmental tissues that in normal development are removed by programmed cell death (apotosis).

Polydactyly

Polydactylia

Presence of additional toes or fingers also called polydactylia or polydactylism. The condition is often treated surgically in the infant.

Ernest Hemingway in the 1930's had a six-toed cat (Snowball) showing a form of polydactyly and cats with a similar condition are now called "Hemingway cats".

(More? Limb Development Abnormalities - Polydactyly)

Polysyndactyly

Developmental abnormality where there is a combination of polydactyly with syndactyly is known as polysyndactyly.


Triphalangeal Thumb (TPT)

Triphalangeal thumb

Developmental abnormality with three phalanges instead of two, forming a long, finger-like thumb. Usually inherited as an autosomal dominant trait, gene locus chromosome region 7q36.


Calcaneovalgus

  • Occurs in about 5% of all newborns.
  • Females are affected more often than males.
  • Deformity can be unilateral or bilateral.
    • external rotation of the calcaneus.
    • an overstretched Achilles tendon.
    • tight anterior leg musculature.

See the review "The Newborn Foot" (2004).[7]

Gastroschisis

By definition, it is a body wall musculoskeletal defect, not a gastrointestinal tract defect, which in turn impacts upon GIT development.

Gastroschisis (paraomphalocele, laparoschisis, abdominoschisis, abdominal hernia) is an abdominal wall defect associated with evisceration of the intestine (2.5 cases/10,000 births), occuring more frequently in young mothers (less than 20 years old). There have been reports that this abnormality is increasing in incidence.

The abnormality is usually situated to the right of the umbilicus and abdominal contents, mainly gastrointestinal, are found outside the anterior body wall.

International Classification of Diseases, 9th Revision diagnosis (756.79) and procedure (54.71) code for gastroschisis (2003 to 2008).

Gastroschisis cartoon.jpg
Can occur in isolation and also in association with other gastrointestinal anomalies (intestinal atresia, perforation, necrosis or volvulus). Defects in other organ systems have been reported in up to 35% of children. There are several theories as to the cause of this abdominal wall defect, including recently failure of the yolk sac and related vitelline structures to be incorporated into the umbilical stalk.[8]

The condition can often be detected by ultrasound scan. Reported as a high mortality defect, only 60% of children survive until the end of the first year of age.

Gastroschisis Ultrasound Quicktime | Flash

Gastroschisis patients are commonly small for gestational age (SGA, birth weight < 10th centile). Frequency line graphs of the birth weight distribution, Kolmogorov-Smirnov test confirmed that this difference was significant (p < 0.001).[9]
  • black line - gastroschisis cases
  • gray line - controls

Gastroschisis Classification

There has been a recent attempt to classify gastroschisis in order to measure clinical outcomes.[10]

  • Simple gastroschisis - intact continuous bowel that is not compromised or breached at delivery or presentation
  • Complex gastroschisis - presence of one or more of intestinal atresia, perforation or intestinal necrosis at delivery or presentation, or missed atresia

Inguinal Hernia

Inguinal hernias are more common in males and associated with the fetal/neonatal developmental descent of the testis through the abdominal wall. The following graphs are from a study of Danish data on postnatal hernia repairs[11]. In contrast, femoral hernia repairs occur mainly in adults in both sexes and increases with age.
