Background:

The reconstruction of the proximal humerus is possible from the resection of the tumor and the placement of a prosthesis. In some cases, they do not meet the anthropometric aspects of the patients.

Objective:

To determine the parameters to size the components of a humeral prosthesis and the development of a set, using design software.

Method:

Forty patients were selected for prostheses, radiographs and CT scans were analyzed and statistical tests were applied to the measurements.

Results:

The length of the tumors was 8-20 cm. The minimum length of the humerus was 28 cm and 33 cm the maximum. Correlation was observed between the humerus and the tumor and the height of the patient with p = 0.93088 and p = 0.904564, respectively; humerus diameter, p = 0.2345. The set will include three components, diameter 6-10 mm, and length of 24, 26 and 28 cm. Three modular spacers with lengths of 6, 8.5 and 13 cm. Crowns 6.5 and 8.5 cm long, 1.3 cm in diameter and 5 mm nut.

Conclusion:

With the development of the set, poorly calculated resections and adaptation to any humerus size can be resolved.
