Developmental dysplasia of the Hip (DDH)

• Etiology / Epidemiology / Natural History• 1/1000 live births, left hip most common • More common in children of central European . • Etiology: multifactorial, genetic, intrauterine mechanical

environment, • DDH Risk factors (five f's)• first born • female • family history • feet( breech position) • fluid(oligohydramnios )

• DDH Clinical Evaluation• Ortolani=out-reduces • Barlow=in-dislocates • Asymmetric gluteal folds • Galeazzi sign: apparent femoral

length discrepancy when the legs are held together with the hips and knees flexed.

• Decreased hip abduction • Ambulatory Patient: flexion

contracture, gluteus medius lurch, toe walking, increased lordosis if bilateral

DDH Associated AnomaliesMetatarsus adductus Hyperextended knees / congenital knee dislocation Torticollis

Treatment Age 0-6 m=Pavlik

Osteomyelitis

• Acute, Sub acute, or Chronic.• The mechanism :exogenous or hematogeneus. • Osteomyelitis :pyogenic or non pyogenic • In infants, the infection can spread to the joint

and cause arthritis. • In children, large sub periosteal abscesses can

form because of the periosteum is loosely attached to the surface of the bone

Pathogenesis

• leukocytes enter the infected area, and, in their attempt to engulf the infectious organisms, release enzymes that lyse the bone.

• Pus spreads into the bone's blood vessels, impairing their flow, and areas of devitalized infected bone, known as sequestra,

• Often, the body will try to create new bone around the area of necrosis. The resulting new bone is often called an involucrum

Cause

Age groupMost common organisms• Newborns (younger than 4 mo)S. aureus, Enterobacter

species, and group A and B Streptococcus species• Children (aged 4 mo to 4 y)S. aureus, group A

Streptococcus species, Haemophilus influenzae, and Enterobacter species

• Children, adolescents (aged 4 y to adult)S. aureus (80%), group A Streptococcus species, H. influenzae, and Enterobacter speciesAdultS. aureus and occasionally Enterobacter or Streptococcus species

• Sickle Cell Anemia Salmonella species

Osteomyelitis

• In adults, vertebrae and the pelvis. • In children, affects the adjacent ends of long

bones. • Fungus :The two most common are Blastomyces

dermatitidis and Coccidioide immitis.• In osteomyelitis involving the vertebral bodies,

about half the cases are due to Staphylococcus aureus, and the other half are due to tuberculosis Pott's disease.

Symptoms of osteomyelitis

• Pain and/or tenderness • Swelling and warmth Fever• Nausea• General discomfort, uneasiness, or ill feeling• Sinuses

• Blood tests• Blood culture.• Needle aspiration• Biopsy: • Bone scan: Technetium-99 pyrophosphate

Treating and managing osteomyelitis

• Drainage• Medications:• Splinting or cast immobilization• Surgery:

Duchenne muscular dystrophy (DMD)

• Recessive X-linked form of muscular dystrophy, which results in muscle degeneration, difficulty walking, breathing, and death.

• 1 in 3,600 -4000 boys.• Females and males are affected, though

females are rarely affected and are more often carriers.

• Caused by a mutation in the dystrophin gene,

• male children before age 5 and may be visible in early infancy.• Progressive proximal muscle weakness of the legs and pelvis

associated with a loss of muscle mass is observed first. Eventually this weakness spreads to the arms, neck, and other areas.

• pseudo hypertrophy (enlargement of calf and deltoid muscles), low endurance.

• As the condition progresses, muscle tissue experiences wasting and is eventually replaced by fat and fibrotic tissue (fibrosis).

• By age 10, braces may be required to aid in walking but most patients are wheelchair dependent by age 12.

• Cardiomyopathy (DCM) , congestive heart failure or arrhythmias

• A positive Gower's' sign• creatinine kinase (CPK-MM) • An electromyography (EMG) shows destruction

of muscle tissue Genetic testing :genetic errors in the Xp21 gene.

• A muscle biopsy or genetic test (blood test) confirms the absence of dystrophin,

• DNA test. DNA testing confirms the diagnosis in most cases.• Muscle biopsy A small sample of muscle tissue is extracted

(usually with a scalpel instead of a needle) and a dye is applied that reveals the presence of dystrophin. Complete absence of the protein indicates the condition.

• Prenatal tests

Treatment

• Comprehensive multi-disciplinary care• Corticosteroids such as Prednisolone and

deflazacort increase energy and strength • beta2-agonists increase muscle strength but do

not modify disease progression. .• Physical therapy • Orthopedic appliances (braces and wheelchairs)• Appropriate respiratory support

Osteoarthritis

• Idiopathic, primary • secondary.• Osteoarthritis causes the formation of hard,

bony enlargements of the small joints of the fingers Heberden's node,

• Another common bony knob (node) occurs at the middle joint of the fingers a Bouchard's node

•

• Osteoarthritis commonly affects the hands, feet, spine, and large weight-bearing joints, such as the hips and knees

• Crystal deposits in the cartilage can cause cartilage degeneration and osteoarthritis.

• Uric acidcrystals cause arthritis in gout,• Calcium pyrophosphate crystals cause

arthritis in pseudo gout

signs you should be aware of include:

• crepitus• restricted movement or range of motion• bony enlargement

• The symptoms include:• persistent knee pain• short-lived morning stiffness• functional limitation

Management

• protect your joints (for example, walking is better for the joints than running).

• diet and aerobic fitness exercises

• Range of motion Quadriceps strengthening

• Patellar taping

• Lateral heel wedges • knee brace for valgus

deformity• NSAID• Intra articularcorticosteroids• intra-articular

hyaluronic acid

• Arthroscopy

• Osteotomy

Definitions Rickets : softening of bones in children due

to deficiency or impaired metabolism of vitaminD, calcium or phosphorus, leading to fractures and deformity.

Predominant cause is vit. D deficiency.

Rickets• Vitamin D 1,25-OH helps calcium

and phosphorous absorption from the intestine, increases kidney reabsorption of phosphorus, and it causes calcium and phosphorus to be released from the bone. Increasing the concentrations of calcium and phosphorus in extracellular fluid causes osteoid cells to calcify. Parathyroid hormone increases the 1-hydroxylation step of vitamin D metabolism and thereby helps regulate calcium metabolism

• Ultraviolet light in the skin changes cholesterol to Vitamin D3 (i.e. cholecalciferol). Vitamin D3 then is hydroxylated in the liver to make Vitamin D 25-OH (i.e. calcidiol, the circulating reserve metabolite). It then undergoes hydroxylation again in the kidney to Vitamin D 1,25-OH (i.e. calcitriol, the active metabolite).
