Pediatric Musculoskeletal Disorders
Key Concepts
    •   Few facts about the pediatric musculoskeletal system:
           – Bones and muscles grow and develop throughout childhood.
           – Bone lengthening occurs in the epiphyseal plates at the ends of bones; when the
               epiphyses close, growth stops.
           – Bone healing occurs much faster in the child than in the adult because the child's bones
               are still growing.• The younger the child, the faster the bone heals.
           – Bone healing takes approximately 1 week for every year of life up to age 10.

    •   Fractured logic
    •   The most common fractures in the child are
            – Clavicular fractures
                    • Clavicular fractures may occur during vaginal birth because the shoulders are the
                        widest part of the body.
            – Greenstick fractures
                    • of the long bones are related to the increased flexibility of the young child's
                        bones.
    •   Clubfoot (talipes),
    •   Developmental hip dysplasia (dislocated hip),
    •   Duchenne's muscular dystrophy,
    •   Fractures,
    •   Juvenile rheumatoid arthritis,
    •   Scoliosis.

Clubfoot
    •   Clubfoot, also known as talipes, is a congenital disorder in which the foot and ankle are twisted
        and can't be manipulated into correct position.
    •   Clubfoot occurs in these five forms:
            – equinovarus:
                     • combination of positions
            – talipes calcaneus:
                     • dorsiflexion, as if walking on one's heels
            – talipes equinus:
                     • plantar flexion, as if pointing one's toes
            – talipes varus:
                     • inversion of the ankles, with the soles of the feet facing each other.
            – talipes valgus:
                     • eversion of the ankles, with the feet turning out
                     •
    •   CAUSES
            – Arrested development during the 9th and 10th weeks of embryonic life, when the feet are
                formed
            – Deformed talus and shortened Achilles tendon
            – Possible genetic predisposition

    •   ASSESSMENT FINDINGS
           – Deformity usually obvious at birth
           – Inability to be corrected manually (distinguishes true clubfoot from apparent clubfoot)
    •   DIAGNOSTIC TEST RESULTS

            –   X-rays show superimposition of the talus and calcaneus and a ladderlike appearance of
                :he metatarsals.

    •   NURSING DIAGNOSES
          – Delayed growth and development
          – Impaired physical mobility
          – Risk for peripheral neurovascular dysfunction

    •   TREATMENT
           – Treatment is administered in three stages:
                 • correcting the deformity either with a series of casts to gradually stretch and
                     realign the angle of the foot
                 • after cast removal, application of Denis Browne splint at night until age 1 or
                     surgical correction
           – maintaining the correction until the foot gains normal muscle balance
           – observing the foot closely for several years to prevent the deformity from recurring.

    •   INTERVENTIONS AND RATIONALES
           – Assess neurovascular status to ensure circulation to foot with cast in place.
           – Ensure that shoes fit correctly to promote comfort and prevent skin breakdown.
           – Prepare for surgery, if necessary, to maintain or promote healing process and to decrease
             anxiety.

    •   Teaching topics
           – Using a blow-dryer on the cool setting to provide relief of itching
           – Importance of placing nothing inside the cast
           – Keeping corrective devices on as much as possible
           – Walking as exercise after surgical repair


Developmental hip dysplasia
    •   Developmental hip dysplasia (dislocated hip) results from an abnormal development of the hip
        socket.
    •   It occurs when the head of the femur is still cartilaginous and the acetabulum (socket) is shallow;
        as a result, the head of the femur comes out of the hip socket.
    •   It can affect one or both hips and occurs in varying degrees of dislocation, from partial
        (subluxation) to complete.

    •   CAUSES
          • Breech delivery
          • Fetal position in utero
          • Genetic predisposition
          • Laxity of the ligaments

    •   ASSESSMENT FINDINGS
           • On the affected side, an increased number of folds on the posterior thigh when the child
             is supine with knees bent
           • Appearance of a shortened limb on the affected side
           • Restricted abduction of the hips

    •   DIAGNOSTIC TEST RESULTS
           • Barlow's sign is present:

                    •   A click is felt when the infant is placed supine with hips flexed 90 degrees, knees
                        fully flexed, and the hip brought into midabduction.

            •   Ortolani's click is present.
                    • It can be felt by the fingers at the hip area as the femur head snaps out of and
                        back into the acetabulum.
                    • It's also palpable during examination with the child's legs flexed and abducted.

            •   Sonography and MRI may be used to assess reduction.

            •   Trendelenburg's test is positive.
                   • When the child stands on the affected leg, the opposite pelvis dips to maintain
                       erect posture.

            •   Ultrasonography shows the involved cartilage and acetabulum.
            •   X-rays show the location of the femur head and a shallow acetabulum; X-rays can also be
                used to monitor progression of the disorder

    •   NURSING DIAGNOSES
          • Delayed growth and development
          • Impaired physical mobility
          • Risk for impaired skin integrity

    •   TREATMENT
           • Hip-spica cast or corrective surgery (for older children)
           • Bryant's traction, if the acetabulum doesn't deepen
           • Casting or a Pavlik harness to keep the hips and knees flexed and the hips abducted for at
             least 3 months

    •   INTERVENTIONS AND RATIONALES
           – Assess circulation before application of cast or traction; after application, have the child
             wiggle toes to detect signs of impaired circulation. The nurse should be able to place one
             finger between the child's skin and cast.
           – Provide skin care to prevent skin breakdown.
           – Give reassurance that early, prompt will probably result in complete correction to
             decrease anxiety.
           – Assure the parents that the child will adjust to restricted movement and return to normal
             sleeping, eating, and play in a few days to ease anxiety.
           – Inspect skin, especially around bony prominences, to detect cast complications and skin
             breakdown.

    •   Teaching topics
           – Correctly splinting or bracing the hips
           – Receiving frequent checkups
           – Coping with restricted movement
           – Removing braces and splints while bathing the child and replacing them immediately
               afterward
           – Stressing good hygiene

Duchennes muscular dystrophy
    •   A genetic disorder that occurs only in males,

______________________________________________________________________ ”Do you 3
know that you are the temple of God and the Spirit of God dwells in you?”     1Corinthians 2:16
______________________________________Pediatric Musculoskeletal Disorders                                     4

    •   Duchenne's muscular dystrophy (also called pseudohypertrophic dystrophy) is marked by
        muscular deterioration that progresses throughout childhood.
    •   It generally results in death from cardiac or respiratory failure in the late teens or early 20s due to
        a defect on the X chromosome, resulting in a lack of production of dystrophin.
    •   The absence of dystrophin results in breakdown of muscle fibers. Muscle fibers are replaced with
        fatty deposits and collagen in muscles.
    •   There's no known cure.

    •   CAUSE
          – Sex-linked recessive trait

    •   ASSESSMENT FINDINGS
           – Begins with pelvic girdle weakness, indicated by waddling gait and falling
           – Cardiac or pulmonary failure
           – Decreased ability to perform self-care activities
           – Delayed motor development
           – Eventual contractures and muscle hypertrophy
           – Eventual muscle weakness and wasting
           – Gowers' sign (use of hands to push self up from floor)
           – Toe-walking
           –
    •   DIAGNOSTIC TEST RESULTS
           – Electromyography typically demonstrates short, weak bursts of electrical activity in
             affected muscles.
           – Muscle biopsy shows variations in the size of muscle fibers and, in later stages, shows fat
             and connective tissue deposits, with no dystrophin.

    •   NURSING DIAGNOSES
          – Impaired gas exchange
          – Impaired physical mobility
          – Impaired walking

    •   TREATMENT
           – Gene therapy (under investigation to prevent muscle degeneration)
           – High-fiber, high-protein, low-calorie diet
           – Physical therapy
           – Surgery to correct contractures
           – Use of devices such as splints, braces, trapeze bars, overhead slings, and a wheel-chair to
             help preserve mobility

    •   INTERVENTIONS AND RATIONALES
           – Perform range-of-motion (ROM) exercises to promote joint mobility.
           – Provide emotional support to the child and parents to decrease anxiety and promote
             coping mechanisms.
           – Initiate genetic counseling to inform the child and family about passing the disorder on to
             future children.
           – If respiratory involvement occurs, encourage coughing, deep-breathing exercises, and
             diaphragmatic breathing to maintain a patent airway and mobilize secretions to prevent
             complications associated with retained secretions.
           – Encourage use of a footboard or high-topped sneakers and a foot cradle to increase
             comfort and prevent footdrop.
           – Encourage adequate fluid intake, increase dietary fiber, and obtain an order for a stool
             softener to prevent constipation associated with inactivity.

    •   Teaching topics
           – Recognizing early signs of respiratory complications
           – Avoiding long periods of bed rest and inactivity; if necessary, by limiting television
               viewing and other sedentary activities
           – Planning a low-calorie, high-protein, high-fiber diet (because child is prone to obesity
               due to reduced physical activity)
           – Helping the child maintain peer relationships and realize his intellectual potential
               (encourage parents to keep child in regular school as long as possible)


Juvenile rheumatoid arthritis
    •   Juvenile rheumatoid arthritis (JRA) is an autoimmune disease of the connective tissue.
    •   It's characterized by chronic inflammation of the synovia and possible joint destruction.
    •   Episodes recur with remissions and exacerbations.
    •   The three main forms of JRA are:
             • pauciarticular JRA
                     • asymmetrical involvement of less than five joints, usually affecting large joints
                          such as the knees, ankles, and elbows.
             • polyarticular JRA
                     • symmetrical involvement of five or more joints, especially hands and weight-
                          bearing joints such as hips, knees, and feet.
                     • Involvement of the temporomandibular joint may cause earache; involvement of
                          the sternoclavicular joint may cause chest pain.
             • systemic disease with polyarthritis
                     • involves the lining of the heart and lungs, blood cells, and abdominal organs.
                     • Exacerbations may last for months.
                     • Fever, rash, and lymphadenopathy may occur.

    •   CAUSES
          • Autoimmune response
          • Genetic predisposition

    •   ASSESSMENT FINDINGS
           • Inflammation around the joints
           • Stiffness, pain, and guarding of the affected joints

    •   DIAGNOSTIC TEST RESULTS

             antibody test. and the presence of rheumatoid factor
           • Slit-lamp evaluation may show iridocyclitis
                  • (inflammation of the iris and the ciliary body).

    •   NURSING DIAGNOSES
           • Disturbed body image
           • Impaired physical mobility

             promote comfort and increase mobility.
           • Apply splints to maintain position of function and prevent contractures.
           • Provide assistive devices, if necessary, to encourage the normal performance of daily
             activities.

    •   Teaching topics
           • Understanding how stress and climate can influence exacerbations
           • Practicing preventive eye care

Scoliosis
    •   Scoliosis is a lateral curvature of the spine, especially among females.
    •   It's commonly identfied at puberty and throughout adolescence.
    •   Scoliosis stops progressing when bone growth stops.


    •   ASSESSMENT FINDINGS
           • Nonstructural scoliosis:
                 • When the child bends at the waist to touch the toes, the curve in the spinal
                     column disappears.
           • Structural scoliosis:
                 • When the child bends forward with the knees straight and the arms hanging down
                     toward the feet, the spinal curve fails to straighten; the hips, ribs, shoulders, and
                     shoulder blades are asymmetrical.

    •   DIAGNOSTIC TEST RESULT
           • X-rays may aid the diagnosis.

    •   NURSING DIAGNOSES
          • Delayed growth and development
