Chondroblastoma is a benign tumor that typically arises in the epiphysis of a long bone. There have been only 2 reported cases of chondroblastoma involving the capitate. This is the first report of chondroblastoma with secondary aneurysmal bone cyst involving the capitate. A 33-year-old man presented with a 3-year history of pain and swelling of the right wrist. Radiography as well as computed ...

An osteoblastoma is a primary benign bone tumor, which is rarely seen in hand bones. Osteoblastoma is generally seen in spine, pelvis, and long bones. However, there are a few case reports of osteoblastoma in wrist and hand bones. To our knowledge, up to now, only one male patient with osteoblastoma in capitate bone was reported. We report the first female case of osteoblastoma of capitate bone...

PURPOSE To review the outcome after intralesional curettage without bone grafting for simple bone cysts in the capitate. METHODS Records of 12 hands in 10 consecutive females aged 14 to 21 (mean, 17.5) years who underwent intralesional curettage without bone grafting for a simple bone cyst in the capitate were reviewed. Clinical outcome was evaluated using the Disabilities of the Arm, Shoulde...

Abstract
 Background: In this study, we examined whether carpal bones (lunate, hamate, capitate) morphologies and fourth metecarp-capitate articulation have an effect on the distal radius fracture pattern.
 
 Methods: 206 patients who applied to emergency department with between 2016-2020 were included in study. Preoperative pre-reduction x-ray films of examined. Lunate, capitate...

Avascular necrosis (AVN) of the capitate bone is very rare. It was first reported by Jonsson in 1942 and about 30 additional cases have been reported since. Most of the cases were associated with serious trauma, but in some cases, severe trauma has not played a major etiologic role. In our case, we propose that the cause of the avascular necrosis of the capitate bone was repetitive minor trauma...

Carpal kinematics have been previously limited to in vitro models with cadaveric specimens. Using a newly developed markerless bone registration algorithm, we noninvasively studied the in vivo kinematics of the capitate, scaphoid, and lunate during wrist extension and flexion in both wrists of 5 men and 5 women. Computed tomography volume images were acquired in neutral and in 2 positions in bo...

The capitate is often considered the "keystone" of the carpus, not simply because of its central and prominent position in the wrist, but also because of its mechanical interactions with neighboring bones. The purpose of this study was to determine in vivo three-dimensional capitate kinematics. Twenty uninjured wrists were investigated using a recently developed, non-invasive markerless bone re...

We report a 15-year-old girl who underwent a mid-carpal fusion for undiagnosed impaction-fractures of the capitate, lunate, and triquetrum after a fall on her outstretched left hand in a dorsiflexed and radially deviated position. The joint was dis-impacted, and the height of the lunate was restored using a cortical bone graft. The damaged proximal capitate articular surface was decorticated to...

PATIENT Male, 13 FINAL DIAGNOSIS: Isolated capitate bone fracture Symptoms: - MEDICATION - Clinical Procedure: - Specialty: - OBJECTIVE Unusual clinical course. BACKGROUND Carpal fractures often appear in men under the age of 40 years. Isolated fracture of the capitate without dislocation is very rare and comprises 1% of all carpal fractures. Nonunion of capitate mostly resulted from dela...
