BACKGROUND CONTEXT: complete or total en bloc spondylectomy has been recommended for giant cell tumors of the spine. Wide local resection of the fifth lumbar vertebra carries potential risks of major complications because of its anatomical features. Only nine cases of the giant cell tumors involving the fifth lumbar vertebra have been reported in the literature. PURPOSE: to present two cases of giant cell tumor of the fifth lumbar vertebra treated by single-stage combined anterior and posterior tumor resection over 7 years of follow-up. STUDY DESIGN: Case report and a review of literature. METHODS: A 33-year-old female and a 20-year-old female, each diagnosed with giant cell tumor of fifth lumbar vertebra, underwent single-stage tumor resection through a combined posterior and retroperitoneal anterior approach. RESULTS: The resection of the fifth lumbar vertebra was completed in the first case without major perioperative complications. In the second case, massive bleeding during the anterior procedure for resection of the vertebral body interrupted the total resection of the tumor, resulting in possible residual tumor which required adjuvant radiotherapy. The patients recovered both clinically and neurologically after the operation. Spinal reconstruction was maintained, and no recurrence of the tumor was evident at the 7-year and 8-year follow-up, respectively. CONCLUSION: There was no recurrence of the tumor after the combined single-stage anterior and posterior tumor resection and adjuvant radiotherapy for the second case for over 7 years follow-up. However, complete resection of the vertebra and tumor at the fifth lumbar vertebra is still challenging to accomplish.  相似文献

Fractures of the atlas   总被引:6,自引:0,他引:6  
Thirty-four patients who had fractures of the atlas (the first cervical vertebra) were reviewed at an average follow-up of 4.5 years. Seventeen patients had bilateral fracture of the posterior arch of the first cervical vertebra. Eight were treated with immobilization in a cervical orthosis, with no long-term problems secondary to the injury. Nine of these patients had additional fractures in the first and second cervical vertebral complex, complicating the management of the fractures of the posterior arch. Two of the nine patients died, and the treatment of the other seven was dependent on the additional fractures. A second group of six patients had a fracture in the area of the lateral mass, with one fracture just anterior to or within the anterior portion of the lateral mass of the first cervical vertebra and a second fracture posterior to the lateral mass of the first cervical vertebra on the same side; resultant asymmetrical displacement of the lateral masses was seen on the open-mouth roentgenogram that was made for each patient. A third group of eleven patients sustained a Jefferson, or burst, fracture of the first cervical vertebra. These patients had either four fractures (two in the anterior arch and two in the posterior arch) or three fractures (one in the anterior arch and two in the posterior arch). Spreading of the lateral masses was relatively symmetrical on the open-mouth roentgenogram. Patients who had fractures with displacement of two to seven millimeters were treated with immobilization in a halo vest. Patients who had fractures with severe spreading of the lateral masses (more than seven millimeters) were treated with reduction of the lateral masses by axial traction until healing of the arch had occurred. No atlanto-axial instability was evident in any patient at follow-up.  相似文献

Ventrolateral cervicotomy provides a narrowed working space for surgical management of upper thoracic spine. We report our experience about ventral upper thoracic spinal cord decompression with reconstruction and plating via the cervicomanubrial route. Six patients (24 to 75 years old) were operated on by the same operator (LN) by cervicomanubriotomy from 2002 to 2007 for upper thoracic spinal cord compression (one case of Pott's disease, three cases of metastases, one fracture, one invasive hemangio-epithelioma), with a good outcome in five patients. Lesions were located from the cervicothoracic junction down to the fourth thoracic vertebra (T4). In all cases, anterior spinal cord decompression, strut graft reconstruction (iliac bone in two cases, cement in four cases) and osteosynthesis were performed. In two cases, a second stage posterior decompression with fixation was performed. The approach begins by a left sided anterior cervicotomy, medial to the sternocleidomastoid muscle and lateral to the trachea and esophagus, associated with division of the infrahyoid muscles close to their insertion at the upper thoracic outlet followed by osteotomy of the manubrium sterni. Then, division of the thyropericardic fascia and thymus, control of the brachiocephalic vein, control of the thoracic lymphatic duct and the horizontal thoracic aorta are performed. The ventral part of fifth cervical vertebra body down to T4 is then exposed between the left primitive carotid artery laterally, the esophagus medially and the thoracic aorta caudally. Compared to total sternotomy without or with clavicle resection, cervicomanubriotomy seems to be a less aggressive, safe and reliable procedure.  相似文献

Abstract:
Objective To investigate procedure and therapeutic effect of resection and reconstruction for axis tumors through the sub mandible approach. Methods Between December 2004 to June 2010,17 patients with axis neoplasm underwent tumor resection and antero-posterior reconstruction through the combined the sub mandible-inner sternocleidomastoid muscle (SMIS) approach and posterior approach. Tumor lesions involved C2 in 11 cases, C2-3 in 4, C2-4 in 2. Eight cases involved vertebral body, and 9 involved both vertebral body and element. Fourteen primary lesions including 4 giant cell tumors, 4 plasmocytomas, 2 chordomas, 2 eosinophilic granulomas, 1 hemangiopericytomas and 1 lymphoma, and 3 metastatic lesions were involved in this study. Three types of reconstruction in upper cervical spine including titanium mesh plus vertically placed titanium plate, titanium mesh plus obliquely placed titanium plate and trimmed titanium mesh alone, were adopted after anterior tumor resection, and then posterior tumor resection and reconstruction were performed. Results All patients experienced pain relief and neurological improvement after surgery. Except for one incidence of screw pull-out which was corrected by a revision surgery, solid fusion was achieved in all patients. A follow-up period of 6 months to 6 years was available for this study. One patient died of cerebral infarction 9 months postoperative. Two patients with chordoma relapsed 13 months and18 months postoperative, respectively, of whom one died of high plegia and respiratory failure, and the other was alive with disease. Two patients with metastasis died of multiple remote metastases 12 months and 18 months postoperative, respectively. Conclusion Through the SMIS apporach, a satisfactory exposure can be obtained for axis tumor resection and reconstruction. Anterior reconstruction of upper cervical spine after tumor resection can be achieved with internal fixation system of cervical spine, which can improve intraopera-tive safety. The combined anterior reconstruction and posterior occipito-cervcial fixation can provide immediate stability, and benefit maintaining stability of upper cervical spine.  相似文献

Upper cervical schwannoma is rare, and belongs to benign tumors that is usually asymptomatic. It accounted for only ten percent of schwannomas cases and mostly occurs in 40e50 years old patients. Aggressive and total resection is the treatment of choice for this tumor. Preoperative diagnosis is difficult, relying on clinical suspicion, and confirmed by surgical pathology. We report a 54-year-old male patient with chief complain of progressive weakness and numbness of his right arm for four months. He had a history of lymph node tumor in 2007 and excised in 2011. Neurological decrease was found on the right arm. The radiographic examination showed lytic lesion on the second, third, and fourth cervical spine. Computed tomography scan showed destruction extending to the first cervical vertebra. Capsulated extradural and extramedullary mass and compression to the spinal cord was found from the magnetic resonance imaging. Two-stage operation was performed. The first stage was posterior decompression with occipitocervical fusion and instrumentation, while the second was anterior decompression and iliac strut graft. Both operations performed using the surgical ultrasonic dissector. During three months'' follow-up, it showed neurological improving. Neurological deficit appears when there is compression on the spinal cord. Total resection is the treatment of choice for these tumors. Preoperative imaging should be performed to exclude malignant tumor and found tumor extension.  相似文献

Many approaches for resection of the superior mediastinal tumors have been reported. We introduce an approach, which we call the cervical anterior approach. This approach is only cervical and does not require a sternotomy. Merits of this approach include the ability to remove the tumor without opening the mediastinal or parietal pleura, as well as obviating draining the thoracic cavity. The tumor is also directly visible, and the surgeon can avoid injury to the great vessels. This approach is recommended when the tumor is located superior to the third thoracic vertebra level, when it borders the great vessels, and when it does not border the trunk of the brachial plexus or nerve root. This approach is easy and safe for surgical procedures.  相似文献

The operative therapeutic principles of thoracic and lumbar spine injuries are based on reposition, decompression and stabilization of the unstable area. Secondary loss of correction and consecutive deformation have negative impact on the long-term results after defect fractures of vertebral bodies and will be minimized only by the reconstruction of all involved spinal columns. With dissemination of thoracoscopic techniques at the thoracic spine and minimal invasive retroperitoneal approaches at the lumbar spine a decrease of the morbidity was achieved with equal effectivity for recalibration and fusion. Our experiences with the first consecutive 42 patients, treated minimal invasive are presented. Indications for anterior thoracoscopic and minimal invasive instrumentations after posterior transfixation are remaining osseous defects of the end plates of more than a quarter of the volume of the involved vertebra in case of migration of the vertebral disc, wedging of the vertebral body after posterior reposition of more than 10 degrees and persisting anterior encroachment of the spinal canal of more than 30 %. The decision is based on radiographs and CT-scans, performed after posterior stabilization.  相似文献

STUDY DESIGN: A case of primary osteogenic sarcoma at the second cervical vertebra is reported. OBJECTIVES: To document an osteogenic sarcoma of the second cervical vertebra and its treatment, and to review the literature. SUMMARY OF BACKGROUND DATA: Primary osteosarcoma of the cervical spine is encountered infrequently, and its location in the upper cervical spine is extremely rare. Two cases of osteosarcoma in the second cervical vertebra have been reported previously in the literature. METHODS: A 15-year-old boy with a mass lesion in the axis was treated surgically by anterior transoral resection, fusion, and reconstruction of the defect with a Harms cage. The resection was completed by posterior excision of the remaining vertebral elements, and by occipitocervical instrumentation and fusion between the occiput and the fourth cervical vertebra. The therapy was completed by adjuvant chemotherapy and radiotherapy. RESULTS: At this writing, 40 months after the initial diagnosis, the patient was in a good state of health with his underlying disease. CONCLUSIONS: The axis is a very rare location for the occurrence of primary osteosarcoma. Osteosarcoma may histologically mimic chondroblastoma. The axis can be surgically exposed, resected, and instrumented transorally. The stabilization must be augmented by posterior occipitocervical fusion.  相似文献

A two-stage combined anterior and posterior approach is commonly used for total resection of giant spinal tumors. However, an anterior approach at the lower lumbar level is technically challenging because of the anatomy of the iliac wing, major vessels and nerves of the lumbosacral plexus. We report a case of fifth vertebral tumor treated posteriorly with a newly devised surgical procedure combined with a recapping transiliac approach. A 45-year-old female diagnosed with giant schwannoma of the fifth lumbar vertebra underwent single-stage posterior tumor resection combined with osteotomy of the lateral part of the iliac crest. Without an anterior approach, tumor excision was completed with a wide view into the fifth lumbar vertebral body. Autogenous bone graft was harvested and used to treat the bone defect. The resected iliac bone was recapped and fixed with screws. The patient was monitored for 8 years without recurrence, and postoperative lumbar alignment remained unchanged. This surgical procedure is safe and a useful adjunct approach for posterior total resection of giant spinal tumors at the lower lumbar level.

Summary The incidence of giant cell tumors accounts for less than 5 % of all bone tumors. In the thoracic spine these tumors are extremely rare (1–1.5 % of the giant-cell tumors). The potential malignant character of giant cell tumors of the spine usually leads to wide surgical extirpation by ventral approach. The filling of bone defects with palacos cement after tumor resection is sufficient in the metaphysis of long bones. The case presented here is a giant cell tumor of the upper thoracic spine with primarily posterior destruction of the vertebral body and left arch. A single dorsal approach allowed for intralesional resection and filling of the defect with bone cement. This procedure was sufficient to achieve a solid fixation without recurrence of the giant cell tumor.   相似文献

We describe a combined surgical technique for tumors of the thoracic spine consisting of a thoracoscopically assisted ventral release followed by a dorsal en bloc spondylectomy and reconstruction. The technique enables thoracoscopic access and release of the involved spinal segment(s) to achieve surgical and histopathologic wide margins, avoiding the disadvantages inherent to thoracotomy. Two patients were successfully treated with solitary tumors involving T10 and T7-8 vertebra. The resection margins were free of tumor. Thoracoscopically assisted total en bloc spondylectomy allows wide excision of thoracic spinal tumors with free resection margins in selected patients; the operation can be performed under direct vision without contamination of uninvolved parts.  相似文献

PURPOSE: Multiple options have been reported for reconstruction of Campanacci grade 3 giant-cell tumor of the distal radius after resection. In 1990, the senior author described an allograft reconstruction combined with a Sauve-Kapandji procedure after distal radius resection and reported preliminary results in 3 patients. The purpose of this study was to assess with validated patient outcome surveys the intermediate to long-term outcomes of all patients treated with this surgery and to analyze their functional results and document tumor control. METHODS: All cases of distal radius osteoarticular allograft combined with the Sauve-Kapandji reconstruction for Campanacci grade 3 giant-cell tumors performed from 1986 to 2000 by a single surgeon were evaluated by clinical and radiologic examinations; the Disabilities of the Arm, Shoulder, and Hand questionnaire; the Short Form-36; and Mayo Wrist scores. RESULTS: Nine consecutive patients (7 women, 2 men) with an average age at follow-up evaluation of 42 years and with a Campanacci grade 3 giant-cell tumor of the distal radius formed the study population. Clinical follow-up time after reconstruction averaged 7 years. Examination showed an average of 51 degrees of extension and 19 degrees of flexion of the wrist and 63 degrees of supination and 79 degrees of pronation of the forearm. Grip strength measured in 5 patients averaged 23 kg. The Disabilities of the Arm, Shoulder, and Hand questionnaire; the Short Form-36; and the Mayo Wrist scores averaged 15, 72, and 73, respectively. These scores indicate modest functional impact. No patient had tumor recurrence, metastases, nonunion, or proximal ulna instability. CONCLUSIONS: En bloc resection of a Campanacci grade 3 giant-cell tumor of the distal radius followed by reconstruction with an osteoarticular allograft and a Sauve-Kapandji procedure with autogenous bone graft results in a reasonable functional outcome at intermediate to long-term follow-up evaluation. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.  相似文献

Although radical resection is the best treatment for local aggressive benign tumors or malignant tumors of the spine, total spondylectomy for lower thoracic vertebrae may cause anterior spinal artery syndrome. There are few reports in the literature in which this syndrome has been documented in association with thoracic spondylectomy, although this syndrome is the most common neurologic complication after abdominal aortic surgery. A 50-year-old woman with a giant cell tumor of the thoracic vertebrae was treated by posterior and anterior surgery. Thoracic segmental arteries from T10 to T12 had to be resected bilaterally to dissect the aorta free from the tumor. After resection of all feeding arteries to the tumor, the tumor and entire parts of T10, T11, and T12 were removed. Postoperative neurologic examination disclosed flaccid paralysis of the lower extremities and sphincter incontinence. Although pain and temperature sensation were absent, vibration and position sense were intact, showing anterior spinal artery syndrome. Intraoperative somatosensory-evoked potential monitoring only showed that transient deterioration failed to adequately reflect this neurologic injury. Major reconstructive surgery involving lower thoracic regions may cause anterior spinal artery syndrome. Somatosensory-evoked potential monitoring might not reliably predict overall neurologic outcome involving the blood supply of the lower thoracic regions.  相似文献

IntroductionA dumbbell-shaped mediastinal granular cell tumor has never been reported, and there have been no reports of dumbbell-shaped tumors resected with a combination of uniportal video-assisted thoracic surgery and the posterior approach.Presentation of caseAn 18-year-old woman was diagnosed with a mediastinal dumbbell-shaped granular cell tumor by computed tomography. Complete resection was achieved via a posterior approach combined with the uniportal video-assisted thoracic surgery. First, a T3 left hemilaminectomy was performed in the prone position and the tumor located inside the intervertebral foramen was removed as far as possible. Next, the patient was repositioned to the right lateral decubitus position, a 2.5-cm skin incision was made on the 4th intercostal posterior axillary line, and resection of the residual tumor was performed. Pathological diagnosis of the resected tumor revealed a benign granular cell tumor. The patient recovered post-surgery and no tumor was reported in the 4-month follow-up magnetic resonance imaging.DiscussionThis is the first reported case of a mediastinal dumbbell-shaped granular cell tumor and its successful resection using a combined posterior and uniportal video-assisted thoracic surgery approach.ConclusionThis is a potentially safe and effective procedure for mediastinal granular cell tumors, with outstanding cosmetic advantages.  相似文献

Destruction of the second cervical vertebra leads to a highly unstable situation. Reconstruction is difficult because the axis plays a central role in rotatory movements and has a unique function in redistributing axial loads. The axis transfers the axial load of the two lateral masses of the atlas to three surfaces on the third cervical vertebra: the two articular facets and the vertebral body. As reconstruction is difficult and the instability in this region is life threatening, pathological processes are often treated less radically compared to other areas of the cervical spine. However, this more moderate approach may result in worse outcomes and prognoses. This paper presents the development of a new implant (C2 prosthesis) and two illustrative cases describing the implementation of this new implant. The C2 prosthesis provides anterior support and therefore allows a more radical surgical approach.  相似文献

IntroductionSuperior sulcus tumors, frequently referred to as Pancoast tumors, are a wide range of tumors invading a section of the apical chest wall called the thoracic inlet. For this reason, a surgical approach and complete resection may be difficult to accomplish. We experienced a locally advanced superior sulcus tumor (SST) located from the anterior to posterior apex thoracic inlet and performed complete resection after definitive chemoradiation.Presentation of caseA 71-year-old Japanese male presented at our hospital due to left back pain and an abnormal chest computed tomography (CT) scan showing 80 × 70 × 60-mm tumor located in the left middle apex thoracic inlet. This tumor was located near the subclavian artery, and the subclavian lymph nodes were swollen. The tumor was found to be an adenocarcinoma (clinical-T3N3M0 stage IIIB). Therefore, we performed definitive chemoradiation therapy. Slight reduction in the tumor size was noted after the treatment, and the subclavian lymph nodes were not swollen. We next performed surgical resection for this SST. Regarding the surgical approaches, the anterior approach was a transmanubrial approach, and the posterior approach was a Paulson’s thoracotomy. In this manner, we were able to perform complete en-bloc resection of this tumor.DiscussionThis surgical approach was effective and safe for treating a SST located from the anterior to posterior apex of the thoracic inlet. The patient remains healthy and recurrence-free at 2.5 years after the operation.ConclusionSurgical approach for SST is difficult. Therefore, this approach is effective and safety.  相似文献
