Traumatic avascular necrosis of the capitate bone—Case report

Vascularized Pedicled Bone Graft for Avascular Necrosis of the Capitate: Case Report

“…Several surgical treatments have been described in the literature, including interposition arthroplasty using tendon graft, 1,2 intercarpal arthrodesis, [3][4][5][6][7][8] silicone athroplasty, 9 -11 resection of the proximal pole and drilling, 12 and free vascularized bone graft from iliac crest. 13 We report here on vascularized pedicled bone graft from the dorsal aspect of the distal radius as a treatment for this rare condition.…”

Postsurgical Rehabilitative Management of Avascular Necrosis in the Capitate

“…Its rarity is thought to be related to the protection it receives by being in the central position in the distal row of the carpals. 2 Factors that may predispose to AVN of the capitate are abnormality in the blood supply, 4 inbuilt carpal instability, major trauma, and minor repetitive trauma. 3,4 Other causes include steroid-induced AVN 5,6 and idiopathic AVN.…”

“…2 Factors that may predispose to AVN of the capitate are abnormality in the blood supply, 4 inbuilt carpal instability, major trauma, and minor repetitive trauma. 3,4 Other causes include steroid-induced AVN 5,6 and idiopathic AVN. 7,8 Diagnosis of AVN has been typically made via plain film radiology, 3 isotope bone scanning, 4 and magnetic resonance imaging (MRI).…”

“…3,4 Other causes include steroid-induced AVN 5,6 and idiopathic AVN. 7,8 Diagnosis of AVN has been typically made via plain film radiology, 3 isotope bone scanning, 4 and magnetic resonance imaging (MRI). 8,9 Treatment of AVN of the capitate consists of conservative splinting 5,10 and surgical intervention.…”

“…8,9 Treatment of AVN of the capitate consists of conservative splinting 5,10 and surgical intervention. Surgical procedures include resection, 11 arthrodesis, 4 drilling, 12 and arthroplasty. 3 There are numerous studies of surgical procedures to help control the pain syndrome and structural integrity.…”
