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

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 articular
corticosteroids
• 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.
Rachitic Changes
Head
craniotabes(soft skull)
frontal bossing
Widening of suture
persistent fontanelae
Delayed dentition &
caries
Rachitic Changes
Abdomen
 Prominent
muscle weakness
 Floppy baby, delayed walking
Pelvis
 Narrow inlet
Rachitic Changes
Widening of wrist, knee and ankle due to
physeal over growth
Rachitic Changes
Chest
Rachitic rosary
Harrison groove
Pigeon chest
Respiratory infection and
atelectasis
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).
Management

Serum cacium
Serum alkaline phosphatase
Serum phosphorus
Bone x-ray
Other tests
