Techniques for Biceps Projection
Step by Step Techniques.
Anterior View . Marking
Posterior View:Marking
Step 1 :Marking the limits of the working area
 The biceps brachii muscle is a twoheaded muscle located in the upper arm, and it plays a crucial role in elbow flexion and forearm supination.
 If you are considering biceps projection, it's important to note that the anatomy of the biceps area is limited by the natural boundaries of the muscle.
Step 2 :How to select anatomically the 2 points of maximum projection
The 2 heads of biceps brachii
their intersection determines the1 st point of maximum projection
I
1 st point of maximum projection
at the intersection of the 2 heads of the biceps brachii
2 nd point of maximum projection
the 2nd point of maximum projection is on the other side of the muscle belly

Step 3 : Division of the biceps working area into squares

Divide the biceps working area into squares with horizontals starting from the elbow towards the shoulder .

The distances between 2 lines equal to 2 times the width of the standard tongue depressors
Step 4 : Division of the biceps working area into squares

Divide the biceps working area into squares with verticals starting inward going out.

The distances between 2 lines equal to 2 times the width of the standard tongue depressors
Step 5 : Division of the biceps working area into squares is ready
The distances between 2 raws as 2 columns equal to 2 times the width of the standard tongue depressors
Step 6 : Vectors

You need to apply vectors normal to the center of each square with a minimum of 0.1 ml .

For bigger squares, the quantity of product should be > 0.1 ml.
Vector normal to the center of an unitarea
Step 7 : Marking the tensors looking at the distal maximal point of projection

The tensors ( here blue arrows) look towards the distal maximal point of projection with a direction and a sense converging all to this distal point of maximal projection.

For each tensor, you need to apply 0.1 ml minimum.

Bigger quantity of product is applied if the square is bigger
Step 8 : Marking the tensors ( in yellow) looking at the proximal maximal point of projection

The tensors ( here yellow arrows) look towards the proximal maximal point of projection with a direction and a sense converging all to this proximal point of maximal projection.

For each tensor, you need to apply 0.1 ml minimum.

Bigger quantity of product is applied if the square is bigger
 The row between the maximal and the distal maximum points of projections has 2 tensors for each square .
 It can be divided in 2 half raws ,
1 superior half raw for the tensors converging to the proximal point of maximum projection and
1 inferior half raw for the tensors converging to the distal point of maximum projection.
Step 9 :
tensors applied to the the row located between the 2 points of maximum projection
0.1 ml for each tensor
Step 10 : Additional Tensors ( here in green)

Additional tensors are done at the end of the procedure to project further the maximum points of projection

from 0.1 to 0.3 ml for each additional tensor
Step 11 : Desinfection

Use an impreganted sheet on the marked area without alcohol.

If possible, we do recommend cetrimide or chlorexhydine without alcohol or citrosil.
Step 12 : Injection of Vectors

1 vector per each square

always inject perpendicular or normal to the center of each square 0.1 ml

you must have a fixed point of support on the patients skin during the injection ( position of hand and fingers is very important) to avoid to inject ,, in the wind,,
Step 13 injection of Tensors
 1 tensor per each square , except for the row located between the 2 points of maximum projection, where each square in such row has 2 tensors
 apply always the syringe on the arrow and inject 0.1 ml without moving the syringe, pushing the needle towards the point of maximum projection.
 the syringe has to be in full contact with the patients skin ( dont put a finger between the syringe and the patients skin)
