Keep as high as possible on thenar eminence, as radial as possible. Minimize PIPJ flexion, release pedicle as soon as possible. More useful in children as the position of the finger leads to significant stiffness in the adult...

Once in the medulla it divides into proximal and distal branches, which supply the inner 2/3 of the cortex. • Metaphyseal arteries anastomose with proximal branches. • Periosteal vessels branch from major limb vessels and course perpendicular to the axis of the tibia thus both sides of a fracture may derive the majority of their blood supply via these vessels as the other sources may be compromised by the...

For a standard cephalogram the distance from object to XR should be 60 inches. The distance from object to film is 6 inches. The central beam is per-pendicular to the ear. The head is held. This gives 10% magnification. Tracing is then performed. • Landmarks: a cephalometric plane connects three or more standardized points. Cephalometric analysis is composed of skeletal, profile and dental analysis. Skeletal analysis: • Used to...

...pliable skin. Skin can cover external and internal on separate paddles. Can use nerves, and has good pedicle. However, the radius may fracture, there may be skin graft loss, visible donor site. Fracture can be reduced by limiting the amount of bone harvested and by avoiding perpendicular osteotomies. Fracture rates as high as 67% have been reduced to 3%. • Iliac crest osseocutaneous flap : provides thick bone with natural curve and good for osseo-integration. However, the soft tissue is bulky and the skin paddle unpredictable. • Scapular osseocutaneous...

Growth perpendicular to the suture is restricted and parallel to it is increased. Purely deformational conditions do not have a compensatory bulge. • 1:2200 live births. • Apert’s syndrome occurs 1:150 000 live births. • Most are sporadic. • 50% involve the sagittal suture. • Syndromes often associated with malformations of limbs, ears, and heart. • Rarely...
