SLIPPED CAPITAL
FEMORAL EPIPHYSIS
(S.C.F.E.)
EPIPHYSIOLYSIS
BY
PROF. HUSSEIN ABDEL FATTAH
Definition


S.C.F.E. is a disorder of the adolescent
hip involving progressive displacement
of the femoral head in relation to the
femoral neck, through the open growth
plate, posteriorly and inferiorly.
However, the epiphysis actually remain
seated in the acetabulum, it is the neck
which displaces usually anteriorly and
superiorly.
ETIOLOGY


Exact cause is disputed.
Multiple interdependent factors
involved.
Risk Factors
•
•
•
•
Overweight.
Abnormally tall child.
Black races.
Endocrinopathies
1 – Biomechanical Factors





Change of physeal angle.
Increase of physeal activity with
growth spurt.
Obesity and lengthening of the neck.
Abnormal retroversion of the neck.
Weakness of the fibrocartilagenous
perichondrial ring of la Croix.
2 – Endocrine Disorders

Harris, (1950)
• Growth Hormone

Widening of physeal plate and reduction of
shearing strength,PITUITARY TUMOURS
• Sex Hormones


Reduction of physeal plate and increase of
shearing strength
Adiposogenital, PITUITARY DIFFICENCY
3 – Metabolic Factors



Decreased Vitamin D activity
Rickets
Renal Osteodystrophy
4 – Inflammation
Morrissy et al, (1983)
Immune complexes in the synovial fluid.
This decreases and disappears when the
head is fixed.
Blood supply of the proximal end of the femur
microstructure of the growth plate
Pathology of S.C.F.E.



The growth plate is widened and irregular
Loose irregular proliferative zone
Disarranged and thickened hypertrophic
zone
• Chondrocytes are clustered, not columnar
• Disturbed endochondral ossification
• Perichondral fibrous ring of LA CROIX is
attenuated
Weakening occurs in the hypertrophic zone of the growth plate
Slipping occur in this zone

Natural History

Time of Presentation:
• 1 – Acute Slip:
 Less than 2 weeks
 Pain in knee, hip and thigh
 Mild trauma
2 – Chronic slip:
More than 3 weeks
Vague thigh and knee pain
Mild hip symptoms
3 – Acute on Chronic Slip
Long duration of symptoms
Acute episode of pain and limping

1 – Pain
Diagnosis
• The commonest presenting symptom:



Vague in the knee and thigh
Exaggerated with activity
Severe in acute episodes
2 – Limping
• Antalgic gait in acute conditions
• Lurching in long standing conditions
• Leg is externally rotated
DIAGNOSIS
continued
3- Deromity External rotation of the
whole limb
• Extension and adduction deformity (on
examination)
• Mild shortening
4 – Hip Movements
• Limited internal rotation, abduction and
flexion
• Flexion of the hip is accompanied by
external rotation and abduction

Degree of Slipping

1. Mild:
• Slipping of less than 1/3 of epiphysis

2. Moderate:
• Slipping of 1/3 to ½ of epiphysis

3. Severe:
• Slipping of more than ½ of epiphysis

Treatment

Aim
• To
• To
• To
• To
stop slipping
enhance healing
correct deformities
avoid complications
Treatment

Non Surgical Treatment
• Prolonged traction in internal rotation
• Immobilization in plaster
• Manipulative reduction (condemned)
Adjuvant Hormonal Therapy
11 Cases
Chorionic Gonadotrophic Hormones.
(1500–5000 units/week)
Surgical Treatment

Epiphyseal Fixation (Pinning) BOYD
• For mild slips and most moderate slips
• Only one or maximum two pins
• In mild slips, inserted from lateral
approach
• In moderate slips, it is inserted from
anterior
Pinning


Pin position in the lower and
posterior half
Upper and anterior position is
dangerous > Penetration and
avascular necrosis




If painful with no slip
Especially in over weight child
Only 10% of painless other side may

Preoperative Traction and Pinning

In acute and acute on top of chronic
cases
• skin Traction in Abduction and internal
rotation by a plaster boot and
derotation bar for few days.
• When reduction is achieved pin fixation
is done.



S.C.F.E. is an ailment of teenagers
Knee pain and limp are early complaints
Early diagnosis by hip examination
clinically is important
Plain X-Ray of both hips in A.P. and A.P.
Lithotomy position is mandatory
C.T. is helpful for further management
Early pinning is the best solution
Prophylactic pinning may be done
Complications chondrolysis early and late
osteoarthritis
Treatment of the predisposing factor is
important
