Question:

Interventions for revascularization of the capitate include:
1. Interposition arthroplasty using tendon graft.
2. Intercarpal arthrodesis.
3. Vascularized pedicled distal radius bone graft based on the fourth extensor compartmental artery.
4. Resection of the proximal pole and drilling.
5. Iliac crest bone grafting.





Answer:

The correct answers for the question "Interventions for revascularization of the capitate include:" are:

1. Interposition arthroplasty using tendon graft.

2. Intercarpal arthrodesis.

3. Vascularized pedicled distal radius bone graft based on the fourth extensor compartmental artery.

4. Resection of the proximal pole and drilling.

5. Iliac crest bone grafting.



Explanation
a. Interposition arthroplasty using tendon graft  (Several surgical treatments have been described in the literature, including interposition arthroplasty using tendon graft, intercarpal arthrodesis, silicone athroplasty, resection of the proximal pole and drilling, and iliac crest bone grafting. Recently, technique of harvesting a vascularized pedicled distal radius bone graft based on the fourth extensor compartmental artery (ECA) with retrograde flow through the fifth ECA from the dorsal intercarpal arch and inserting it into the capitate from a dorsal approach has been advocated).

b. Intercarpal arthrodesis (Several surgical treatments have been described in the literature, including interposition arthroplasty using tendon graft, intercarpal arthrodesis, silicone athroplasty, resection of the proximal pole and drilling, and iliac crest bone grafting. Recently, technique of harvesting a vascularized pedicled distal radius bone graft based on the fourth extensor compartmental artery (ECA) with retrograde flow through the fifth ECA from the dorsal intercarpal arch and inserting it into the capitate from a dorsal approach has been advocated).

c. Vascularized pedicle distal radius bone graft based on the fourth extensor compartmental artery (Several surgical treatments have been described in the literature, including interposition arthroplasty using tendon graft, intercarpal arthrodesis, silicone athroplasty, resection of the proximal pole and drilling, and iliac crest bone grafting. Recently, technique of harvesting a vascularized pedicled distal radius bone graft based on the fourth extensor compartmental artery (ECA) with retrograde flow through the fifth ECA from the dorsal intercarpal arch and inserting it into the capitate from a dorsal approach has been advocated).

d. Resection of the proximal pole and drilling (Several surgical treatments have been described in the literature, including interposition arthroplasty using tendon graft, intercarpal arthrodesis, silicone athroplasty, resection of the proximal pole and drilling, and iliac crest bone grafting. Recently, technique of harvesting a vascularized pedicled distal radius bone graft based on the fourth extensor compartmental artery (ECA) with retrograde flow through the fifth ECA from the dorsal intercarpal arch and inserting it into the capitate from a dorsal approach has been advocated).

e. Iliac crest bone grafting (Several surgical treatments have been described in the literature, including interposition arthroplasty using tendon graft, intercarpal arthrodesis, silicone athroplasty, resection of the proximal pole and drilling, and iliac crest bone grafting. Recently, technique of harvesting a vascularized pedicled distal radius bone graft based on the fourth extensor compartmental artery (ECA) with retrograde flow through the fifth ECA from the dorsal intercarpal arch and inserting it into the capitate from a dorsal approach has been advocated).

Abstract
Avascular necrosis of the capitate is a rare entity. The most common reported etiology is trauma. We report a case of avascular necrosis of the capitate in a patient with chronic wrist pain that began after a single episode of remote trauma.
