An orthopedic device for a shoulder joint includes a patient-specific alignment guide. The alignment guide includes a cap having a three-dimensional engagement surface customized in a pre-operative plan by computer imaging to be complementary and closely mate and conform to a humeral head of a proximal humerus of a patient. The alignment guide includes a tubular element extending from the cap and defining a longitudinal guiding bore for guiding an alignment pin at a patient-specific position and orientation determined in the pre-operative plan, and an orientation feature on the cap. The orientation feature is designed to orient the cap relative to the humeral head when the orientation feature is aligned with a landmark of the proximal humerus.
1. An orthopedic device for a shoulder joint comprising: a patient-specific alignment guide including:a cap comprising a hemispherically-shaped shell, the shell having an exterior surface and a customized interior surface configured to be complementary and match at a selected particular position on
1. An orthopedic device for a shoulder joint comprising: a patient-specific alignment guide including:a cap comprising a hemispherically-shaped shell, the shell having an exterior surface and a customized interior surface configured to be complementary and match at a selected particular position on a humeral head of a specific patient, and the shell including a peripheral edge that terminates at a portion of an anatomic neck of the humeral head, a periphery of the cap being configured to surround an anatomic neck of the humeral head;an elongated tubular element extending from the cap and defining a longitudinal guiding bore configured for guiding an alignment pin at a patient-specific position and an orientation determined in the pre-operative plan;a tab extending away from the periphery of the cap, the tab configured and sized and shaped to be received at least partially in a bicipital groove of the humeral head to orient the cap relative to the humeral head when the orientation feature is aligned with the bicipital groove; anda resection formation provided at the periphery of the cap, the resection formation being configured for guiding a resection of the anatomic neck of the humeral head. 2. The orthopedic device of claim 1, wherein the resection formation is a slot along a portion of the periphery of the cap at a patient-specific orientation relative to the alignment pin. 3. The orthopedic device of claim 1, wherein the resection formation is an edge along a portion of periphery of the cap. 4. The orthopedic device of claim 1, further comprising the alignment pin. 5. The orthopedic device of claim 4, further comprising a sizer template mountable over the alignment pin after the humeral head is resected and the patient-specific alignment guide is removed. 6. The orthopedic device of claim 1, further comprising a sizer template having a radial slot, the sizer template mountable over the alignment pin after the humeral head is resected and the patient-specific alignment guide is removed. 7. An orthopedic device for a shoulder joint comprising: a patient-specific alignment guide including:a cap having a three-dimensional engagement surface customized in a pre-operative plan by computer imaging to closely mate and conform to a corresponding humeral head of a proximal humerus of a patient, a periphery of the cap being configured to surround an anatomic neck of the humeral head;a tubular element extending from the cap and defining a longitudinal guiding bore for guiding an alignment pin at a patient-specific position and an orientation determined in the pre-operative plan; anda tab extending from the cap, the tab configured to be at least partially received into a bicipital groove of the proximal humerus to orient the cap relative to the proximal humerus;wherein the alignment guide is configured to be removed from the humeral head after insertion of the alignment pin into the humeral head without removing the alignment pin. 8. The orthopedic device of claim 7, further comprising the alignment pin. 9. The orthopedic device of claim 7, wherein the resection slot extends along a portion of the periphery of the cap. 10. The orthopedic device of claim 7, further comprising a resection formation provided at the periphery of the cap, the resection formation being a resection slot configured for guiding a resection of the anatomic neck of the humeral head. 11. An orthopedic device for a shoulder joint, comprising: an alignment guide including: a hemispherically-shaped shell, the shell having an exterior surface and a customized interior surface configured to be complementary and match at only a single position on a humeral head of a specific patient, and the shell including a peripheral edge that terminates at a portion of an anatomic neck of the humeral head;a lip extending radially outward and entirely about the peripheral edge of shell;a rectangular-shaped tab extending axially outward from the peripheral edge of the shell, the tab being configured and sized to be received within a bicipital groove of the humeral head to orient the shell relative to the humeral head when the tab is aligned with a landmark of the proximal humerus;an elongated tubular element extending axially outward from the exterior surface of the shell, the tubular element defining a guiding bore configured to guide an alignment pin to a predetermined location of the humeral head at a patient-specific orientation; andan elongated resection slot formed in a portion of the lip, the elongated resection slot being configured for guiding a patient-specific resection of the anatomic neck of the humeral head,wherein the alignment guide is configured to be removed from the humeral head after insertion of the alignment pin into the humeral head without removing the alignment pin; andthe tab has a width less than a diameter of the elongated tubular element.
