CUBITAL FOSSA

→ Be right there always my PT

→ Elcow extended

→ FA supination

CARRYING ANGLE

(Present when)

→ Elbow flexion > 30 degrees

→ FA pronation

CARRYING ANGLE

(Absent when)

Normal Carrying Angle

Excessive Carrying Angle

Cubilus Varus

Gunstock deformity

Types of Carrying Angle

5-10 degrees

Degrees in male

10-15 degrees

Degrees in female

cubitus valgus

→ > 15 (degrees)

cubitus varus

→ < 5 (degrees)

gunstock deformity

→ -15 (degrees)

Brachioradialis

→ Shunt 

→ Elbow flexion in mid-pronation

→ Increased activity in fast flexion, or when resisted

Biceps Brachii

→ Affected by FA position

→ Spurt

Brachialis

→ Unaffected by FA position

→ Chief elbow flexor

→ Spurt
