A case report of coronal fractures through the hamate,the capitate,and the trapezoid

To our knowledge, the simultaneous coronal fractures of the hamate, capitate, and trapezoid have not been previously reported in the literature. There were few reports about coronal fractures of the hamate caused only by axial loading to the ulnar column. We report 43-year-old man who presented with painful swelling on the dorso-ulnar side of the wrist after striking a wall with his right clenched fist. The computed tomography scan demonstrated coronal fractures through the hamate, capitate, and trapezoid. We performed closed reduction and fixation with a percutaneous compression screw. At the last follow-up, the patient was able to return to sports activities without any symptoms.     

Fractures of the scaphoid, capitate and triquetrum in a child: a case report

Carpal fractures in children are rare, especially with a combination of scaphoid, capitate, and triquetrum fractures. We report one such case in a 10-year-old boy who was successfully treated with Kirschner wires.     

Giant cell tumor of the capitate. A case report.

Giant cell tumors in the small bones of the hand are unusual, particularly in the carpus. A 28-year-old woman developed a giant cell tumor in the capitate. After biopsy, she was treated with complete excision of the capitate with no reconstruction. Five years later she had excellent hand function and no tumor recurrence. A careful roentgenographic and pathologic examination will distinguish between aneurysmal bone cysts and giant cell reparative granulomas. Complete excision of the involved bone is recommended.     

Simultaneous fractures of the capitate and hamate in the coronal plane: case report

Fractures of the carpal bones in the coronal plane are encountered rarely and their diagnosis usually is delayed. Coronal hamate fractures are relatively well described but a coronal capitate fracture occurring simultaneously with a coronal hamate fracture is extremely rare. We describe such an injury addressed with fixation of the hamate alone.     

Failure of initial surgical treatment of a giant cell tumor of the capitate and its salvage: a case report

Giant Cell Tumors are rare tumors in the young adult and localisation in the hand is even more exceptional. In the absence of adjuvant treatment, the literature reports a strong potential for local recurrence of between 75 and 86%. These tumours also have a risk of sarcomatosis degeneration and pulmonary metastasis. The case report concerns a 24-year-old patient, with a Giant Cell Tumour of the capitate initially diagnosed on simple curettage, and we describe her treatment together with the treatment of a subsequent reccurrence. A literature review will also highlight the current knowledge of this disease.     

A giant cell tumor of the thumb: a case report

Giant cell tumors of the flexor sheath are the second most common tumors of the hand. We present a case that is unusual in the extent of the tumor and the pronounced bony invasion, which is rare. Preoperative diagnosis was complicated by a history of gout in our patient.     

Complex carpal dissociation with open, complete, and divergent trapezium, capitate, and hamate dislocation: a case report

We report a patient with a unique complex carpal dissociation involving complete and divergent dislocation of the hamate, capitate, and trapezium with total ligamentous disruption of the distal carpal row and midcarpal joint, associated with a transverse shaft fracture of the fifth metacarpal. The mechanism of injury was a sustained torsional force resulting in a simultaneous distraction and bidirectional dorsopalmar (ulnar)-palmodorsal (radial) crushing force at the carpus.     

Renal cell carcinoma with metastases to the triquetrum: case report

Metastatic tumors of the hand are rare, with fewer than 200 cases reported in the literature. Renal cell carcinoma is among the most common tumors to metastasize, but we are not aware of reports of this tumor metastasizing to the carpal bones. We describe a case of renal cell carcinoma that metastasized to the triquetrum to draw attention to the potential for such lesions developing within the hand and wrist.     

Giant cell tumor of soft tissues: A case report of extra-articular diffuse-type giant cell tumor of the quadriceps

IntroductionGiant cell tumors of soft tissue (GCTs) are a relatively rare entity. It is a distinct but uncommon group of neoplasms morphologically identical to osseous giant cell tumor. The diffuse type of extra-articular GCT arising within muscle is a rare benign soft tissue tumor with a wide spectrum of clinical presentation.Presentation of caseThis article reports a rare case of a 44-year-old woman with a mass arising from her right thigh. MRI showed only a few areas of low T2 signal in a mass that was hyper intense to muscle. Histopathology of this lesion located within the right quadriceps muscle revealed admixture of multinucleated giant cell with mononuclear cells. This patient was treated by surgical resection and followed up for recurrence.DiscussionDiffuse-type GCTs are commonly located in the periarticular soft tissues, but on rare occasions these lesions can be purely intramuscular or subcutaneous and can be challenging to diagnose. Characteristic findings include gradient echo secondary to hemosiderin deposition, and the low signal on T2.ConclusionBecause extra-articular diffuse-type GCTs are rare, the differential diagnosis is challenging. The clinical outcomes of diffuse-type GCTs are unclear because of their rarity. Benign clinical course is expected if the lesion is excised adequately.     

Multifocal clear cell meningioma in the spine: A case report

Clear cell meningioma is a rare morphologic form of meningioma. This case report describes a very rare case of multifocal clear cell meningioma in the thoracic and lumbar spine. A 9 year old patient presented with back pain and popliteal pain, which were aggravated by trunk motion and knocking. Magnetic resonance imaging (MRI) suggested a meningioma at the L2 level. An intradural extramedural tumor attached to the cauda equina was surgically removed and pathological diagnosis was clear cell meningioma. The patient began to complain of back pain at the Th12 level 4 months postoperatively. Retrospective analysis of MRI before the first operation revealed the small tumors at Th12 and L5 levels; comparison with a new MRI showed the rapid growth in 4 months. Adjunctive surgical resection was carried out and the back pain disappeared. These tumors had the same pathological findings. In conclusion, in young patients with suggested meningioma in the lumar spine, clear cell meningioma should also be considered, and the possibility of multifocal occurrence and postoperative recurrence must be taken into account.     

Simultaneous fracture of the hamate and the capitate bones

A fracture of both the hamate and capitate bones in a child is described. The literature is reviewed with special attention to the treatment of these rare fractures.     

Simultaneous fracture of the hamate and the capitate bones

Summary A fracture of both the hamate and capitate bones in a child is described. The literature is reviewed with special attention to the treatment of these rare fractures.

Zusammenfassung Es wird über ein 8 Jahre altes Kind berichtet, welches sich eine Fraktur sowohl des Os hamatum als auch des Os capitatum zugezogen hat. Anhand der Literatur werden verschiedene Behandlungsmäglichkeiten sowohl konservative als auch operative diskutiert. Im vorliegenden Fall kam es unter konservativer Behandlung zur Ausheilung.

     

Multicentric giant cell tumor involving the same foot: A case report and review of literature

Multicentric giant cell tumour (GCT) is extremely rare; no case has been previously reported where two lesions occurred in the same foot at different sites. We report a case involving the calcaneus and subsequently the 3^rd toe of the same foot and review the reported literature. In established cases of multicentricity, the histopathology has to be properly reviewed and the patient has to be followed up for a longer time with serial whole body assessment to pick up any subsquent lesions. The treatment of the local disease does not differ from a standard GCT.
