2. DEFINITION
STRESS FRACTURE OF PARAS INTERARTICULARLS
Spondylolysis is a unilateral or bilateral bony defect in the
pars interaticulris or isthmus of the vertebra.
It can cause a slipping of the vertebra, in which case the term spondylitis
spondyloysthesis is used.
3.
4. ETLOLOEY
Affects 3-6% of population
This condition appears in the first or second decade of life;
the frequency of spondyloyis increases with age until 20
years. There is, however, no change in prevalence with
increasing age from 20 to 80 years old.
Men are affected twice as often as women.
5. There is increased prevalence in specific ethnic. Sports and
family groups.
Sponyloysis occurs more frequently in the young athletic
population.
There is increased risk in gymnasts, football players,
cricketers, swimmers, divers, weight lifters and wrestlers.
6. Spondylolysis is considered to be a stress fracture that result
from mechanical stress at the pars interatcualris
These stress fractures occur due to repetitive load and
rather then being coursed by a single traumatic event
Occurs mostly at L5 (80-95%):sue to repetitive
hyperextension, which increases the contact between the
caudal edge of the inferior articular facet of l4 and the pars
interarticularis
7. CLINICAL FEATURES
Onset of pain
Possible history of local trauma
Intense pain restricts activities of daily or sporting
performance
Symptoms become aggravated after a stressful event
Rest usually relieves the symptoms
8. C/F LUMBAR SPONDYLOYSIS
Focal low back pain with radiation into the buttock or thigh
with no neurological deficit.
Children under 13 years old show tenderness or pain on
extension
Children can present a posture deformity or abnormal gait
pattern.
Pain throughout limber rang of movement
16. ON EXAMINATION
Hyperlordotic posture
Low back pain during lumber extension
Para spinal muscle spasm and hamstring tightness is present
Neurologic exam is usually normal but neurogenic
symptoms can arise if the condition progresses to
spondylisthesis
17. STROK TEST
Performed to assess localised spondyloysis pain
The patient stands on one leg with other foot resting on one
leg with other foot resting on the weight bearing knee.
The patient then hyper extends the lower back
Positive test: reproduction of lower back pain suggest limber
spondyloysis.
18. MEDICAL MANGMENT
NSALDS to provide pain relief
Cessation of aggregating activities
The use of a spinal brace to prevent motion at the injured
pars and allow bony repair
Physical therapy
19. SURGICAL TREATMENT
May be required.
This only occurs in some patients and evidence of long-term
benefit is still uncertain.
Latest procedures attempt a repair of the affected pars with
preservation of the segmental mobility whereas earlier
method sometimes included a spinal fusion procedure.
20.
21. PHYSICAL THERAPY MANGMENT
GOALS
Reduce pain
Promoting normal movement patterns
Global and specific strengthening exercises
Optimization of physical function
22. A rehabilitation program should progress in four stages:
Control pain and inflammation
Strength and flexibility
Stabilization
Functional movement
23. Control pain and inflammation
Deep heating modalities: for pain relief
Taking stress off the injured area allows physiological healing
processes to take place.
It may be necessary to avoid rotational shearing forces and
extension movements by a temporary cessation of sporting
activities / wearing a brace.
24. Strength and flexibility
Exercises to improve relaxation and aenral mobility of spine
are initiated first.
As para spinal muscle spasms and hamstrings tightness are
often seen in patient can be added to the rehabilitation
program.
Flexibility training is useful in patient with hypermobility of
the spine.
25. Functional movement
The main goal of physiotherapy is to increase functional
abilities through a home exercise program.
As soon as primary pain decreases, patient have to be
encouraged to resume activities as tolerated.
