– See: – Proximal Frx – Distal Frx – Rotational Alignment – Deforming Forces: – muscular forces deform the femur after fracture; – abductor muscles: – abducts proximal femur following subtrochanteric & high proximal shaft fractures; – psoas: – proximal 1/3 frx of shaft are also … Read more
– See Quads – Origin: – Straight Head: Anterior Inferior Iliac Spine – Reflected Head: Groove on upper brim of acetabulum; – Insertion: Upper border of patella by the ligamentum patella into tibia tuberosity; – Reversed origin-insertion action: Flexes the pelvis on the femur and gives anterior stabilization to the pelvis; … Read more
– Discussion: – these plates are used with 3.5 mm cortex screws; – their main application is for use with pelvic and acetabular frx; – they may be also used in fractures of the distal humerus (dorsolateral apect), the clavicle, and the calcaneus; – reconstruction plates have notches … Read more
– Discussion: – specially designed to be bent and twisted in two dimensions; – hence they are useful for the pelvis; – already low strength of the plate is further diminshed by three dimensinal bending; – bending angles greater than 15 deg at any one site must be … Read more
