Scoliosis

Scoliosis Scoliosis is defined as an abnormal curvature and rotation of the spine

Types of Scoliosis Functional scoliosis It is a curvature due to a problem that does not involve the spine, such as having legs that are different lengths or muscle spasms caused by pain. These can cause to lean to the side, creating the appearance of scoliosis. The curvature is flexible and will go away if the problem that causes to lean to the side goes away. Structural scoliosis The spine curvature is not flexible and does not go away with a change in position. There is no evidence that functional scoliosis will lead to structural scoliosis.

Cont… Idiopathic structural scoliosis (80% of children with structural scoliosis ) Structural scoliosis associated with other conditions In about two out of every 10 cases, children with structural scoliosis also have one of these conditions: Born with vertebrae that do not develop normally (congenital scoliosis) An underlying problem in the brain or spinal cord, such as a cyst or a tumor. A problem with nerves or muscles, such as cerebral palsy or muscular dystrophy.

Cobb method Measuring the degree of scoliosis : - choose the most tilted vertebrae above and below the apex of the curve. The angle between intersecting lines drawn perpendicular to the top of the top vertebrae and the bottom of the bottom vertebrae is the Cobb angle.

Cobb`s method

Treatment Early detection of the curve A curve that is obvious in standing position has already approached 30 – 40 degree. The treatment depends on the age of the patient and the severity of the curve

Cont.. Nonsurgical treatment : Generally accepted guidelines : Curves of less than 20 degree in skeletally immature persons are examined every 6 months Curves less than 20 degree in skeletally mature persons require no further evaluation Curves of more than 20 degree in skeletally immature patients should be examined every 3 – 4 months Orthotic TX. For curve more than 25 degree Curves more than 30 – 40 degree in skeletally mature persons do not require Tx .but they are examined radiographically for progression every 2 – 3 years

Charleston Bending Brace

Surgical treatment Indication : Curves more than 50 degree in the mature patients Curves more than 10 degree with marked rotations Double major curves more than 30 degree Idiopathic scoliosis

Cont… Distractive techniques Halopelvic a: pre-operation b: after anterior release and halo-pelvic traction. c: after second stage correction d: follow-up 6 months later.

Halofemoral distraction A-B: AP radiographs before treatment showing right thoracic scoliosis measured 92°. C:Bending films showed right thoracic scoliosis corrected to 77°. D:The right thoracic curve correction obtained with Halo-femoral traction treatment was 40.2%. E-F:The major curve measured 35° after posterior spinal fusion G-H: AP and lateral radiographs at 20-month follow-up showed solid spinal fusion with a 37° right thoracic curve.

Kyphosis Also called as Scheuermann's disease; Roundback; Hunchback; Postural kyphosis Defined as increase in normal posterior convexity of the thoracic spine

Cont…

Causes Degenerative disease (such as arthritis) Developmental problems Trauma Other causes of kyphosis include: Certain endocrine diseases Connective tissue disorders Disk degeneration Infection (such as tuberculosis) Muscular dystrophy Neurofibromatosis Paget's disease Polio Spina bifida Tumors

Symptoms Difficulty breathing (in severe cases) Fatigue Mild back pain Round back appearance Tenderness and stiffness in the spine

Types Knuckle : prominence of single spinous process indicating collapse of single vertebra Angular : 2 – 3 vertebral body are collapsed Round : several vertebrae are involved and hence gives a round appearance

Investigations : - Treatment : - X – ray of the thoracic spine CT scan MRI Treatment : - Mild : anterior hyperextension bracing Severe : Surgical decompression

Cont…

Complications - Decreased lung capacity Disabling back pain Neurological symptoms including leg weakness or paralysis Round back deformity

Perthes' disease It is a condition where the top of the thigh bone (the femoral head) softens and breaks down. It occurs in some children and causes a limp and other symptoms. The bone gradually heals and reforms as the child grows. The aim of treatment is to ensure that the femoral head regrows back into its normal shape so that the hip joint can function well.

Cont…

Cont… Occurs in a part of the hip joint called the 'femoral head'. Injury to the small blood vessels which supply the femoral head with blood. So, parts of the femoral head lose their blood supply. As a result, the bone cells in the affected area die and so the bone 'softens', and can fracture or become distorted. Over several months the blood vessels regrow, and the blood supply returns to the bone tissue. New bone tissue is laid down, and so the femoral head regrows.

Cont… Femoral head forms a good spherical (rounded) shape. This helps it fit well into the hip joint socket. If the femoral head is less rounded, hip movements may be affected and there may be more 'wear and tear' on the hip joint.

Symptoms Limp. gradually worse over a few weeks. Pain in the hip and groin area (radiate to the knee or thigh ). Stiffness and reduced range of movement of the affected hip. The affected leg may become slightly thinner (wasted), because it is not used as much as the other leg. Shortening of leg

Diagnosed Examination of the hip, X-ray (both hips ) Others test : MRI scan, Bone scan and Arthrogram (an X-ray where dye is injected into the joint space). Blood tests, or a sample of fluid from the joint (to rule out other problems such as infection ).

Treatment The aim of treatment is to promote the healing process and to ensure that the femoral head remains well seated in the hip socket as it heals and regrows. Treatment depends on the age of the child and the severity of the condition. Treatments may include 'observation', bed rest and crutches, a plaster cast or special leg brace, or surgery.

Nonsurgical Treatment Anti-inflammatory ----- ibuprofen Encouraged to walk with crutches and participate in physical therapy. Bed rest in traction . With physical therapy, the child will be shown some simple exercises to do until the final stage of healing has occurred. - Hip abduction - Hip rotation

Observation and physiotherapy In the past, children with Perthes' disease were treated with a plaster cast, a brace, or surgery. However, it is now known that at least half of cases heal well without any treatment, particularly children aged five and under, and milder cases. Most children with Perthes' disease can be treated by physiotherapy and home exercises - these are to keep the hip joint mobile and in a good position in the hip socket. Regular reviews to check how the femoral head is healing. Advice may include to encourage swimming (to keep the hip joint active in the full range of movements), but Avoid heavy impact on the joint such as running or jumping. Bed rest and/or crutches : - if symptoms are bad.

Plaster casts or a special brace Considered in more severe cases or in older children. The aim is to keep the femoral head well positioned in the hip socket (slightly pointing outwards). Special braces (also called called 'orthotic' devices') may be advised.

Surgery Help to keep the femoral head well positioned, or can improve the shape and function of the joint if it has not healed well.
