A patient-specific alignment guide includes a patient-specific portion and a guiding element having a through opening. The patient-specific portion has a patient-specific surface preoperatively configured to mate as a negative of a portion of an iliac crest of a pelvis of a specific patient and mate to the iliac crest only in one position. The guiding element has a preoperatively configured orientation and location relative to the patient-specific portion for preparing a bore in the bone of the patient to direct a bone screw at the preoperatively configured orientation and location for sacroiliac fixation.
1. A method for lumbopelvic fixation comprising: providing a convertible patient-specific alignment guide for a patient's pelvis, the convertible patient-specific alignment guide including first and second patient-specific portions coupled by a bridge;intraoperatively selecting one of unilateral fix
1. A method for lumbopelvic fixation comprising: providing a convertible patient-specific alignment guide for a patient's pelvis, the convertible patient-specific alignment guide including first and second patient-specific portions coupled by a bridge;intraoperatively selecting one of unilateral fixation, iliac fixation, sacral fixation and bilateral sacroiliac fixation procedure for the patient; andreconfiguring the convertible patient-specific alignment guide to a corresponding patient-specific alignment guide for the selected fixation procedure. 2. The method of claim 1, further comprising: selecting a unilateral fixation procedure for a first side of the pelvis;removing the bridge and the second patient-specific portion;registering a patient-specific surface of the first patient-specific portion on a first iliac crest of the patient; anddrilling a bone bore for a bone screw through a guiding element of the first patient-specific portion into the first iliac crest. 3. The method of claim 2, further comprising: removing the first patient-specific portion; andresecting a portion of the iliac crest around the bone bore for seating a bone screw assembly. 4. The method of claim 1, further comprising: selecting a bilateral fixation procedure for the pelvis;registering a first patient-specific surface of the first patient-specific portion on a first iliac crest of the patient;registering a second patient-specific surface of the second patient specific portion on a second iliac crest of the patient; anddrilling first and second bone bores for first and second bone screws through corresponding first and second guiding elements coupled to the corresponding first and second patient-specific portions and into the first and second iliac crests. 5. The method of claim 4, further comprising: removing the convertible alignment guide; andresecting first and second portions of the corresponding first and second iliac crests around the corresponding first and second bone bores for seating corresponding first and second bone screw assemblies. 6. A method for lumbopelvic fixation comprising: providing a convertible patient-specific alignment guide for a pelvis of a patient, the convertible patient-specific alignment guide including first and second modular portions coupled to each other;selecting one of unilateral fixation, iliac fixation, sacral fixation and bilateral sacroiliac fixation procedure for the patient; andconfiguring the convertible patient-specific alignment guide to arrange the first and second modular portions to correspond to the selected fixation procedure. 7. The method of claim 6, wherein: the first and second modular portions comprise: an iliac guiding element; anda sacral guiding element; andselecting one of unilateral fixation, iliac fixation, sacral fixation and bilateral sacroiliac fixation procedure for the patient comprises:selecting unilateral fixation; andselecting one or both of the iliac guiding element and the sacral guiding element for fixation to the pelvis. 8. The method of claim 7, wherein configuring the convertible patient-specific alignment guide to arrange the first and second modular portions to correspond to the selected fixation procedure includes: selecting one of the iliac guiding element and the sacral guiding element; anduncoupling the selected one of the iliac guiding element and the sacral guiding element from the convertible patient-specific alignment guide. 9. The method of claim 8, further comprising: registering a first patient-specific surface of the selected one of the iliac guiding element and the sacral guiding element on the pelvis of the patient;drilling a bone bore for a bone screw through the selected one of the iliac guiding element and the sacral guiding element into the pelvis;removing the selected one of the iliac guiding element and the sacral guiding element; andresecting a portion of the pelvis around the bone bore before seating a bone screw assembly. 10. The method of claim 7, wherein configuring the convertible patient-specific alignment guide to arrange the first and second modular portions to correspond to the selected fixation procedure includes: detaching an arm connecting the iliac guiding element and the sacral guiding element. 11. The method of claim 6, wherein: the first and second modular portions comprise: a first patient-specific iliac guiding element; anda second patient-specific iliac guiding element; andselecting one of unilateral fixation, iliac fixation, sacral fixation and bilateral sacroiliac fixation procedure for the patient comprises: selecting bilateral fixation;selecting both of the first and second patient-specific iliac guiding elements for fixation to the pelvis. 12. The method of claim 11, wherein the first patient-specific iliac guiding element and the second patient-specific iliac guiding element include a first sacral guiding element and a second sacral guiding element, respectively. 13. The method of claim 12, wherein configuring the convertible patient-specific alignment guide to arrange the first and second modular portions to correspond to the selected fixation procedure includes: detaching a first arm and a second arm connecting the first sacral guiding element and the second sacral guiding element to the first patient-specific iliac guiding element and the second patient-specific iliac guiding element, respectively. 14. The method of claim 13, wherein configuring the convertible patient-specific alignment guide to arrange the first and second modular portions to correspond to the selected fixation procedure includes: detaching the first arm and the second arm from a bridge connecting the first and second patient-specific iliac guiding elements. 15. The method of claim 12, further comprising uncoupling one or both of the first sacral guiding element from the first patient-specific iliac guiding element and the second sacral guiding element from the second patient-specific iliac guiding element. 16. The method of claim 15, further comprising: registering a first patient-specific surface of the first patient-specific iliac guiding element on a first iliac crest of the patient;registering a second patient-specific surface of the second patient-specific iliac guiding element on a second iliac crest of the patient;drilling first and second bone bores for first and second bone screws through corresponding first and second guiding elements coupled to the corresponding first and second patient-specific iliac guiding elements and into the first and second iliac crests;removing the convertible alignment guide; andresecting first and second portions of the corresponding first and second iliac crests around the corresponding first and second bone bores for seating corresponding first and second bone screw assemblies. 17. A method for lumbopelvic fixation comprising: evaluating a convertible patient-specific alignment guide for a pelvis of a patient, the convertible patient-specific alignment guide including an iliac guiding element and a sacral guiding element coupled to each other;selecting between performing one or both of an iliac fixation procedure and a sacral fixation procedure for the patient; andreconfiguring the convertible patient-specific alignment guide to a corresponding patient-specific alignment guide for the selected fixation procedure. 18. The method of claim 17, wherein reconfiguring the convertible patient-specific alignment guide comprises uncoupling an arm connecting the iliac guiding element and the sacral guiding element. 19. The method of claim 17, wherein reconfiguring the convertible patient-specific alignment guide comprises uncoupling a drill guide from a patient-specific base. 20. The method of claim 17, wherein reconfiguring the convertible patient-specific alignment guide comprises uncoupling a bridge from the convertible patient-specific alignment guide.
