glenoidplanefitting.algorithms.vault module

This is an implentation of the vault method, see

Matsumura N et al. Computed tomography measurement of glenoid vault version as an alternative measuring method for glenoid version. Journal of Orthopaedic Surgery and Research 2014, 9:17

glenoidplanefitting.algorithms.vault.create_vault_line(anterior_point, posterior_point)

Determines the second point needed to form the Friedman line :param anterior_point: First point on glenoid line, anatomically defined

as a point on the anterior margin of glenoid

Parameters

posterior_point – Second point on glenoid line anatomically defined as a point on the posterior margin of glenoid

Returns

The midpoint of the glenoid line, or the second point of for the vault line

glenoidplanefitting.algorithms.vault.vault_version(anterior_point, midpoint, vaultpoint)

Determines the glenoid version using the glenoid vault as reference :param anterior_point: First point on glenoid line, anatomically defined

as a point on the anterior margin of the glenoid

Parameters

• midpoint – Second point on the vault line, anatomically defined as the midpoint of the glenoid fossa

• vaultpoint – First point on the vault line, anatomically defined as the tip of the glenoid vault

Returns

The glenoid version (positive value indicates retroversion)
