1/33. Spinal biomodeling.STUDY DESIGN: A prospective trial of stereolithographic biomodeling in complex spinal surgery. OBJECTIVES: To investigate the use of stereolithographic biomodeling as an aid to complex spinal surgery. SUMMARY OF BACKGROUND DATA: Of the array of imaging methods available to assist the spinal surgeon, no single method provides a complete overview of the anatomy, although three-dimensional imaging has been shown to have advantages. methods: Stereolithographic biomodeling is a new technology that allows data from three-dimensional computed tomographic scans to be used to generate exact plastic replicas of anatomic structures. Five patients with complex deformities were selected: two children with congenital deformities, a patient with an osteoblastoma, a patient with basilar invagination caused by osteogenesis imperfecta, and a patient with a failed lumbar fusion. Computed tomographic scanning was performed and stereolithographic biomodels generated. The stereolithographic biomodels were used for patient education, operative planning, and surgical navigation. RESULTS: The surgeons reported that biomodeling was useful in complex spinal surgery and was an effective technology. Stereolithographic biomodels were found to be particularly useful in morphologic assessment, in the planning and rehearsal of surgery, for intraoperative navigation, and for informing patients about surgical procedures. CONCLUSIONS: Stereolithographic biomodeling allows imaging data to be displayed in a physical form. This intuitive medium may improve data display and allows surgical simulation on a proxy of the surgical site. Draw-backs of the technology were a minimum 24 hours' manufacturing time and the cost.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
2/33. Group B streptococcal vertebral osteomyelitis with bacteraemia in an adult with no debilitating condition.A previously healthy 62-year-old immunocompetent woman presented with group B streptococcal vertebral osteomyelitis. Group B streptococcus was recovered in 3 consecutive blood cultures. The patient recovered fully after treatment including antibiotic therapy, bed rest and physical rehabilitation. Group B streptococcal vertebral osteomyelitis is uncommon and has not previously been reported in patients with no immunosuppressive condition.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
3/33. Chronic paronychia, osteomyelitis, and paravertebral abscess in a child with blastomycosis.blastomycosis is an unusual fungal infection in children. It is often a chronic infection characterized by granulomatous and suppurative lesions. Clinical manifestations include either pulmonary findings or disseminated disease. Disseminated blastomycosis usually begins with a lung infection that spreads to the skin, bones, and central nervous system. This is a case report of a child with chronic blastomycosis presenting with chronic paronychia, fever, cough, malaise, and back pain. The child underwent surgical drainage of a paravertebral abscess and administration of intravenous amphotericin b. He was discharged in good condition on oral therapy with ketoconazole. The literature on blastomycosis, with particular emphasis on clinical presentations and management, is reviewed. When the history and physical examination suggest a chronic granulomatous or disseminated disease, such as tuberculosis, the physician must include blastomycosis in the differential.- - - - - - - - - - ranking = 5.2528365558444keywords = physical examination, physical (Clic here for more details about this article) |
4/33. Tophaceous gout of the spine mimicking epidural infection: case report and review of the literature.OBJECTIVE AND IMPORTANCE: Tophaceous gout uncommonly affects the axial skeleton. The clinical presentations of gout of the spine range from back pain to quadriplegia. gout that presents as back pain and fever may be difficult to distinguish from spinal infection. We present a case of a patient with tophaceous gout of the lumbar spine who was initially diagnosed with and treated for an epidural infection. The clinical and diagnostic features of tophaceous gout of the spine are reviewed. CLINICAL PRESENTATION: A 70-year-old man presented with a 2-day history of fever and back pain. A physical examination revealed that he had flank tenderness and evidence of polyarthritis affecting the elbows, knees, and right first metatarsophalangeal joint. A magnetic resonance imaging scan of the patient's lumbar spine showed an extensive area of abnormal gadolinium enhancement of the paramedian posterior soft tissues from L3 to S1 with an area of focal enhancement extending into the right L4-L5 facet joint. INTERVENTION: A laminectomy was performed at L4-L5, and a chalky white material in the facet joint was found eroding into the adjacent pars intra-articularis. light and polarizing microscopy confirmed the presence of gouty tophus. No evidence of infection was found. CONCLUSION: Gouty arthritis of the spine is rare. Thirty-seven previous cases have been reported. When the clinical presentation includes acute back pain and fever, differentiation of spinal gout from spinal infection may be difficult. The clinical suspicion of spinal gout may lead to the correct diagnosis by a less invasive approach than exploration and laminectomy.- - - - - - - - - - ranking = 5.2528365558444keywords = physical examination, physical (Clic here for more details about this article) |
5/33. The use of traction methods to correct severe cervical deformity in rheumatoid arthritis patients: a report of five cases.STUDY DESIGN: A case series is presented. OBJECTIVES: To describe the methods of correction used in this study for flexible severe cervical deformity, and to report the results in patients with rheumatoid arthritis. SUMMARY OF BACKGROUND DATA: Long-standing rheumatoid arthritis can lead to severe cervical deformity, causing significant functional deficits and poor cosmesis. Information on the use of traction combined with surgical stabilization to achieve correction of flexible deformity in rheumatoid patients is sparse in the English literature. methods: A review of five cases, including pertinent history, physical examination, radiographic evaluation, traction techniques, surgical stabilization, and outcomes, was conducted. RESULTS: Excellent correction of deformity and radiographic union were achieved in all the patients. One patient had minimal loss of correction after surgery and thereafter remained stable. Pin tract infections were the only significant complication. CONCLUSIONS: Severe cervical flexible deformity in rheumatoid patients can cause significant disability and can be treated successfully with a combination of traction techniques and surgical stabilization.- - - - - - - - - - ranking = 5.2528365558444keywords = physical examination, physical (Clic here for more details about this article) |
6/33. Acute paraplegia in a patient with spinal tophi: a case report.A 28-year-old man with a 5-year history of gouty arthritis suffered from an acute episode of lower back pain. He visited a rehabilitative clinic and received physical therapy following his examination. Weakness and numbness of both lower legs developed rapidly after physical therapy. He was sent to our hospital with complete paralysis of both lower limbs and complete sensory loss below the umbilicus 3 hours after the physical therapy. No peripheral tophi were found. myelography showed an extrinsic compression of the dura sac at T10. Emergency decompressive laminectomy of T9 to T11 was performed. During the surgery, caseous material was found deposited in the ligamentum flavum and the left T9 to T10 facet joint, with indentation of the dura sac. The pathologic diagnosis was spinal tophi. After surgery, the patient's neurologic function recovered rapidly. It was suspected that inappropriate physical therapy might have aggravated acute inflammation of spinal gout and resulted in a rapid deterioration of neurologic function. Though gout is a chronic medical disease, an acute attack of spinal gout may be disastrous and requires emergency neurosurgical intervention.- - - - - - - - - - ranking = 4keywords = physical (Clic here for more details about this article) |
7/33. Musculoskeletal causes of chest pain.BACKGROUND: chest pain is a common presenting problem to general practitioners and accident and emergency departments. Such a symptom generates anxiety in both patients and their medical attendants, for fear that this symptom represents a life threatening event. Numerous investigations often ensue, adding to the physical and financial burden on an already stressed health system. Musculoskeletal causes of chest pain are common but frequently overlooked. OBJECTIVE: This article aims to outline some of the more common musculoskeletal problems which may present as chest pain, and to present a practical approach to their diagnosis and management. DISCUSSION: It is estimated that somewhere in the vicinity of 20-25% of noncardiac chest pain has a musculoskeletal basis. Careful history taking to identify red flag conditions differentiates those who require further investigation. Historical features suggesting a musculoskeletal cause include pain on specific postures or physical activities. A musculoskeletal diagnosis can usually be confirmed by clinical examination alone, the key to which is reproducing the patient's pain by either a movement or more specifically palpation over the structure that is the source of the pain. Confirming the diagnosis, explanation and reassurance allay anxiety. Management strategies include manual therapy, the provision of analgesia and anti-inflammatory agents, either topically, orally or by injection. Focal injection of local anaesthetic alone may also be a useful diagnostic and therapeutic tool.- - - - - - - - - - ranking = 2keywords = physical (Clic here for more details about this article) |
8/33. New-onset neurologic deficits after general anesthesia for MRI.Two patients with spine disease were unable to tolerate supine placement for magnetic resonance imaging (MRI) because of severe back pain. General anesthesia was administered to enable the patients to undergo MRI. Both patients awakened from anesthesia with new-onset paraplegia and underwent emergency decompressive laminectomy. Acute paraplegia after anesthesia occurs infrequently and is most commonly associated with mechanical injury, vascular compromise, or anesthetic technique. The physical limitations of the MRI environment make it difficult to position some patients in a manner that accommodates their pathophysiology and may place certain patients at risk of neurologic compromise. For this subset of patients, the necessity of MRI with general anesthesia should be reassessed and alternative imaging methods considered.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
9/33. Unicameral bone cyst in the spinous process of a thoracic vertebra.Unicameral bone cysts affecting the spine are extremely rare and tend to be misdiagnosed. We report on a 17-year-old female patient who presented with a 2-year history of persistent low back pain. The radiographic evaluation and bone scan failed to reveal a pathologic process. Magnetic resonance of the painful area and subsequent computed tomography scan showed a well-circumscribed osteolytic lesion originating from the spinous process and extending into both laminae of T9 vertebra. Aneurysmal bone cyst or osteoblastoma was considered to be the most probable diagnosis. The patient underwent excisional biopsy of the tumor. The intraoperative findings were suggestive of solitary bone cyst, a diagnosis that was confirmed histologically. Because the tumor had not invaded the articular facets, no posterolateral spine fusion was required. The patient had an unremarkable postoperative clinical course. Her symptoms resolved and she returned to her previous level of physical activities. Unicameral bone cysts, although uncommon, should be included in the differential diagnosis of an osteolytic lesion involving the spine.- - - - - - - - - - ranking = 1keywords = physical (Clic here for more details about this article) |
10/33. confusion as the presenting manifestation of vertebral osteomyelitis: a case report.A 44-year-old patient presented with increasing confusion. He was first diagnosed as having intermittent pressure hydrocephalus but a further evaluation showed CSF pleocytosis and hypoglycorrhachia. Five weeks later, his physical examination was unrevealing. Nuclear imaging techniques were conflicting, with negative gallium- and indium-labelled white blood cells scans but a Tc scan pointing towards a vertebral infection. A well-demarcated lesion in the T9 vertebral body, demonstrated by CT scan, confirmed the diagnosis of vertebral osteomyelitis. Although we were unable to recover the causative organism, antibiotic treatment for presumed staphylococcal osteomyelitis resulted in full recovery. This case indicates that vertebral osteomyelitis may cause significant meningeal inflammation even in the absence of epidural or subdural abscess. We recommend that in patients with meningitis without a clear etiology vertebral osteomyelitis should be considered and pursued with CT scannings of the vertebrae, a procedure that can yield positive findings even when other scanning modalities are negative.- - - - - - - - - - ranking = 5.2528365558444keywords = physical examination, physical (Clic here for more details about this article) |
