Results
43-year-old man with history of Neurofibromatosis presented with signs and symptoms of myelopathy with spastic lower extremities and gait difficulties. Imaging studies demonstrated a severe kyphotic deformity of the cervical spine with associated cord compression secondary to an anteriorly positioned plexiform neurofibroma. Two-stage surgical procedure was designed to treat this lesion. Stage I consisted of tracheostomy placement, transmandibular, circumglossal approach to the anterior cervical spine, C2–C6 corpectomies, and C1–C7 reconstruction with a custom titanium cage/plate. Stage II consisted of suboccipital craniectomy, C1–C2 laminectomies, and occipital-cervical thoracic instrumented fusion (O-T8). There were no operative complications, but the patient did develop a small pulmonary embolism post-operatively treated with anticoagulation. Patient required two-weeks of inpatient rehabilitation following surgery. Gastrostomy tube and tracheostomy were successfully discontinued with preserved swallowing and respiratory function. Patient-reported outcome measurements revealed significant and sustained improvement post-operatively.
Conclusions
Five-level cervical corpectomy including C2 can be safely and successfully performed via a transmandibular, circumglossal approach. Circumferential reconstruction utilizing a custom anterior titanium cage and plate system manufactured from a pre-operative CT scan was utilized in this case. Long segment occipital-cervical-thoracic reconstruction is recommended in such a case. Using such a technique, improvement in myelopathy, correction of deformity, and improved quality of life can be achieved.
Management of metastatic spine disease is quite complex. Advances in research have allowed surgeons and physicians to better provide chemotherapeutic agents that have proven more efficacious. Additionally, the advancement of surgical techniques and radiosurgical implementation has altered drastically the treatment paradigm for metastatic spinal disease. Nevertheless, the physician–patient relationship, including extensive discussion with the neurosurgeon, medicine team, oncologists, radiation oncologists, and psychologists, are all critical in the evaluation process and in delivering the best possible care to our patients. The future remains bright for continued improvement in the surgical and nonsurgical management of our patients with metastatic spine disease.
Methods
We include an evidence-based review of decision making strategies when attempting to determine most efficacious treatment options. Surgical treatments discussed include conventional debulking versus en bloc resection, conventional RT, and radiosurgical techniques, and minimally invasive approaches toward treating metastatic spinal disease.
Conclusions
Surgical oncology is a diverse field in medicine and has undergone a significant paradigm shift over the past few decades. This shift in both medical and surgical management of patients with primarily metastatic tumors has largely been due to the more complete understanding of tumor biology as well as due to advances in surgical approaches and instrumentation. Furthermore, radiation oncology has seen significant advances with stereotactic radiosurgery and intensity-modulated radiation therapy contributing to a decline in surgical treatment of metastatic spinal disease. We analyze the entire spectrum of treating patients with metastatic spinal disease, from methods of diagnosis to the variety of treatment options available in the published literature. 相似文献
Background contextWound dehiscence and surgical site infections (SSIs) can have a profound impact on patients as they often require hospital readmission, additional surgical interventions, lengthy intravenous antibiotic administration, and delayed rehabilitation. Negative pressure wound therapy (NPWT) exposes the wound site to negative pressure, resulting in the improvement of blood supply, removal of excess fluid, and stimulation of cellular proliferation of granulation tissue.PurposeTo assess the incidence of wound infection and dehiscence in patients undergoing long-segment thoracolumbar fusion before and after the routine use of NPWT.Study designRetrospective study.Patient sampleOne hundred sixty patients undergoing long-segment thoracolumbar spine fusions were included in this study.Outcome measuresPostoperative incidence of wound infection and dehiscence.MethodsAll adult patients undergoing thoracolumbar fusion for spinal deformity over a 6-year period at Duke University Medical Center by the senior author (CB) were included in this study. In 2012, a categorical change was made by the senior author (CB) that included the postoperative routine use of incisional NPWT devices after primary wound closure in all long-segment spine fusions. Before 2012, NPWT was not used. After primary wound closure, a negative pressure device is contoured to the size of the incision and placed over the incision site for 3 postoperative days. We retrospectively review the first 46 cases in which NPWT was used and compared them with the immediately preceding 114 cases to assess the incidence of wound infection and dehiscence.ResultsOne hundred sixty (NPWT: 46 cases, non-NPWT: 114 cases) long-segment thoracolumbar spine fusions were performed for deformity correction. Baseline characteristics were similar between both cohorts. Compared with the non-NPWT cohort, a 50% decrease in the incidence of wound dehiscence was observed in the NPWT patient cohort (6.38% vs. 12.28%, p=.02). Similarly, compared with the non-NPWT cohort, the incidence of postoperative SSIs was significantly decreased in the NPWT cohort (10.63% vs. 14.91%, p=.04).ConclusionsRoutine use of incisional NPWT was associated with a significant reduction in the incidence of postoperative wound infection and dehiscence. 相似文献
BackgroundIncidental durotomies occur in up to 17% of spinal operations. Controversy exists regarding the short- and long-term consequences of durotomies.PurposeThe primary aim of this study was to assess the effect of incidental durotomies on the immediate postoperative complications and patient-reported outcome measures.Study designProspective study.Patient sampleA total of 1,741 patients undergoing index lumbar spine fusion were selected from a multi-institutional prospective data registry.Outcome measuresPatient-reported outcome measures used in this study included back pain (BP-Visual Analog Scale), leg pain (LP-Visual Analog Scale), and Oswestry Disability Index.MethodsA total of 1,741 patients were selected from a multi-institutional prospective data registry, who underwent primary lumbar fusion for low back pain and/or radiculopathy between January 2003 and December 2010. We collected and analyzed data on patient demographics, postoperative complications, back pain, leg pain, and functional disability over 2 years, with risk-adjusted propensity score modeling.ResultsIncidental durotomies occurred in 70 patients (4%). Compared with the control group (n=1,671), there was no significant difference in postoperative infection (p=.32), need for reoperation (p=.85), or symptomatic neurologic damage (p=.66). At 1- and 2-year follow-up, there was no difference in patient-reported outcomes of back pain (BP-Visual Analog Scale), leg pain (LP-Visual Analog Scale), or functional disability (Oswestry Disability Index) (p>.3), with results remaining consistent in the propensity-matched cohort analysis (p>.4).ConclusionWithin the context of an on-going debate on the consequences of incidental durotomy, we found no difference in neurologic symptoms, infection, reoperation, back pain, leg pain, or functional disability over a 2-year follow-up period. 相似文献
AbstractObjective:Primary cervical spinal tumors are rare tumors of the spine and are associated with significant morbidity and mortality. Such tumors include multiple myeloma, chordomas, giant cell tumors, hemangiomas, osteosarcomas, chondrosarcomas, synovial sarcomas, aneurysmal bone cysts (ABC), hemangiomas, eosinophilic granulomas, osteoid osteomas, and osteoblastomas. We review the surgical decision-making process and identify critical key steps for surgical complication avoidance. We also present case illustrations demonstrating such pathological diagnoses and surgical treatments performed.Methods:We retrospectively review the literature regarding the most common primary cervical spinal tumors that have undergone surgical resection with or without adjuvant treatment.Results:En bloc resection of primary cervical tumors resulted in significantly increased progression-free survival and overall survival. From the limited data, adjuvant treatment with proton-beam therapy for chordomas has potential benefit. Neo-adjuvant chemotherapy for Ewing’s sarcoma and osteogenic sarcoma has shown some promise, with en bloc resection demonstrating stronger benefit for osteogenic sarcoma.Discussion:En bloc resection for primary spinal tumors has proven to be the standard of care in spinal oncology. Adjuvant and neo-adjuvant treatments such as chemotherapy and radiotherapy variants (conventional, proton beam, cyberknife) need to be studied further in most primary tumor types to become standard of care. Chordoma management is more widely studied with en bloc resection and adjuvant proton-beam therapy demonstrating improved progression-free survival and overall survival. Surgical management and adjuvant treatment strategies are case dependent, depending on tumor histology, patient neurological examination, prior surgeries at that level, and prior adjuvant treatment. 相似文献
OBJECTIVE: Several authors have noted increased neurological deficits and worsening dysesthesia in the postoperative period in patients with spinal cord ependymoma. We describe the neurological progression and pain evolution of these patients over the 1-year period after surgery. In addition, our favored method of en bloc tumor resection is illustrated, and the rate of complications, recurrence, and survival in this group of patients is addressed. METHODS: We operated on 26 patients (12 male and 14 female) with low-grade spinal cord ependymomas between 1975 and 2001. The median age at diagnosis was 42 years. Tumors extended into the cervical cord in 13 patients, the thoracic cord in 7 patients, and the conus medullaris in 6 patients. Eleven patients had previous surgery and/or radiation therapy. RESULTS: We achieved a gross total resection in 88% of patients, whereas 8% had a subtotal resection and 4% had a biopsy. Only 1 patient developed a recurrence over a mean follow-up period of 31 months. CONCLUSION: We conclude that radical surgical resection of spinal cord ependymomas can be safely achieved in the majority of patients. A trend toward neurological improvement from a postoperative deficit can be expected between 1 and 3 months after surgery and continues up to 1 year. Postoperative dysesthesias begin to improve within 1 month of surgery and are significantly better by 1 year after surgery. The best predictor of outcome is the preoperative neurological status. 相似文献
Although radical resection prolongs the disease-free survival period, surgical management of primary sacral tumors is challenging because of their location and often large size. Moreover, in cases of lesions for which a radical resection necessitates total sacrectomy, reconstruction is required. The authors have previously described a modified Galveston technique in which a liaison between the spine and pelvis is achieved using lumbar pedicle screws and Galveston rods embedded into the ilia; additionally, a transiliac bar reestablishes the pelvic ring. Although this reconstruction technique achieves stabilization, several biomechanical limitations exist. In the present report the authors present the case of a patient who underwent spinal pelvic reconstruction after a total sacrectomy was performed to remove a giant sacral chordoma. They describe a novel spinal pelvic reconstruction technique that addresses some of the biomechanical limitations. 相似文献
Synovial chondromatosis is an uncommon disorder characterized by the formation of multiple cartilaginous nodules within the synovium, most commonly affecting large joints. Its involvement with the spine is rare; only six cases have been reported. The authors describe two patients with synovial chondromatosis involving the cervical spine. In the first case, synovial chondromatosis arose from the left C1-2 facet joint. This patient underwent a two-stage procedure including a posterior approach for tumor resection and occipitocervical fusion as well as a transmandibular circumglossal approach to the anterior craniocervical junction to complete the tumor removal. Interestingly, on histopathological examination, scattered foci of low-grade chondrosarcoma were intermixed within the synovial chondromatosis. To the authors' knowledge, this is the first report of secondary low-grade chondrosarcoma arising in vertebral synovial chondromatosis. In the second case, synovial chondromatosis involved the left C4-5 facet joint. Tumor resection and cervical fusion were performed via a posterior approach. In this report, the authors describe the clinical presentation, radiographic findings, operative details, histopathological features, and clinicoradiological follow-up data obtained in these two patients and review the literature pertaining to this rare entity. 相似文献
