Poliomyelitis

Viral infection of anterior horn cells

Causing permanent paralysis of isolated groups of muscles

Clinical features

The affected limb is wasted and deformed

The paralytic limb is floppy( LMNL)

±Scoliosis

±Short limb

Normal sensation

Principles of Treatment

)1(Isolated muscle weakness without deformity

( a )Quadriceps paralysis = Splint Or Surgery

( b )Weak thumb opposition = Tendon transfer

(2 )Unbalanced Paralysis) One group is paralysed(

(a )Passively corrected = Splint OR Tendon Transfer

)b (Fixed Deformity = Surgery( Correction + Stabilization)

) c (Paralytic Scoliosis = Spinal fixation

•(3 )Balanced Paralysis) Flial Joint( :

Permanent Splintage OR Arthrodesis

(4 )Limb Shortening : ˂ 3 cm = Raised Shoe

˃ 3 cm = Limb Lenghening
