小儿脊柱爆裂型骨折 总被引:2,自引:0,他引:2
目的:探讨小儿脊拄爆裂型骨折的特性、诊断与治疗、并比较与成人同类骨折的不同特点。资料与方法:1974~1994年间收治的小儿创伤性、闭合性脊柱损伤中,有11例诊为爆裂型骨折。平均年龄为144岁,男5例,女6例。平均随访时间为9年(2~16年)。按照Denis爆裂型骨折分类法,4例为A型;6例为B型;1例为C型。根据伤后的严重程度,6例行后路融合和器械固定,5例卧位.石膏和支具治疗。结果:随访发现90%患儿有满意的功能结果。伤后及随访时的X线摄片评价表明手术治疗能够改进和维持骨折部位的后凸畸形(伤后平均19°.随访时12°),椎体前侧压缩改进15%(伤后平均39%,随访时24%)。而非手术治疗的后凸畸形平均进展9°(伤后平均15°,随访时为24°),椎体前侧压缩进展8%(伤后平均36%.随访44%),3例合并有神经系统症状患儿,2例有明显改进。结论:1.由于小儿脊柱的解剖特点,爆裂型骨折的诊断与治疗有其特性。2、与成人同类骨折相比,骨折的稳定性较好,神经系统症状轻。3、手术治疗可稳定骨折,并防止后凸畸形和椎体前侧压缩的进一步发展,减步住院或卧床时间。4、非手术治疗对无神经系统症状的稳定骨折是有效治疗手段,但在伤后1年中,后凸畸形和椎体前侧压缩有轻度、渐进性的发展趋势。 相似文献

椎体成形术对胸腰椎爆裂型骨折的治疗意义 总被引:51,自引:2,他引:51
目的:探讨腰腰椎爆裂型骨折撑开复位与椎体成形术后椎体结构和生物力学性能的变化。方法:收集6具新鲜成人尸体的胸腰椎标本,制成T11-L1、L2-L4、T12-L2节段标本共10具,用自由落体撞击试验造成中间椎体爆裂型骨折,撑开复位、用注射型自固定磷酸钙人工骨行椎体成形术。分别于骨折前、骨折撑开复位后、椎体成形术后用薄层CT扫描测量中间椎体内空隙,用双能X线骨密度仪测定骨密度,用万能材料试验机测定骨折前、椎体成形术后中间椎体与其上方椎间盘在前屈、后伸、侧屈和扭转就压力 下刚度的变化,并比较成形术后的伤椎及其下方的完整椎体的抗极限压缩测试结果。结果:8具标本造中间椎体爆裂型骨折模型成功。(1)骨折前椎体内无明显空隙;骨折并撑开复位后椎体内空隙体积平均为5.25cm^3,占椎体总体积的13.9%;椎体成形术后空隙减少,与骨折前相比差异无显著性意义。(2)骨折前椎体骨密度在正常范围,骨折并撑开复位后骨密度较骨折前降低;椎体成形术后,骨密度较骨折复位后及骨折前均明显升高。(3)椎体成形术后,伤椎的刚度与骨折前相比差异无显著性意义,抗极限压缩强度的均值低于其下方完整椎体,但差异无显著性意义;伤椎上方椎间盘在前屈和后伸应力下的刚度小于骨折前,但在侧屈应力下差异无显著性意义;标本在扭转应力下的刚度小于骨折前。结论:(1)撑开复位未能恢复胸腰椎爆裂型骨折椎体结构上的完整性,这可能是后路切开复位内固定术后发生内固定失败与矫正度丢失的重要原因。(2)应用注射型自固化磷酸钙人工骨行椎体成形术有助于伤椎的重建,术后脊柱的生物力学特性接近骨折前水平。 相似文献

INTRODUCTION
Four-part proximal humeral fractures require surgical intervention. However, they can be difficult to diagnose in radiological images. We aim to define a new, easily recognisable, radiological sign as a predictor of four-part fracture of the proximal humerus in a plain anteroposterior radiograph of the shoulder.PATIENTS AND METHODS
We describe our ‘sunset’ sign as ‘articular surface of humeral head pointing away from the glenoid and tilted upwards, in the presence of a displaced greater tuberosity fracture’. We postulate that a patient with proximal humerus fracture showing this sign has four-part fracture until proven otherwise. Between 2002 and 2006, 80 consecutive patients had surgical treatment of their proximal humeral fractures in our unit. Pre-operative radiographs and operative notes of 79 patients were evaluated independently by three blinded observers. The presence of ‘sunset’ sign was recorded. Findings were then correlated with the operative diagnoses to confirm whether they were four-part fractures or not. With 95% confidence interval, we calculated the sensitivity, specificity, positive and negative predictive values for our diagnostic sign.RESULTS
Of 79 patients, 30 displayed ‘sunset’ sign in their pre-operative radiograph. Of these, 28 had confirmed four-part fractures operatively. The positive predictive value of ‘sunset’ sign was 93%. The specificity and sensitivity were 95% and 78%, respectively. The sensitivity was affected by eight patients with four-part fractures with displaced articular head fragment which had dropped either medially or posteriorly.CONCLUSIONS
These results suggest that, in patients with proximal humeral fractures, the presence of ‘sunset’ sign in the anteroposterior radiograph is a reliable indicator of four-part fracture. 相似文献12.
A comparative study of computed tomographic and plain radiographic methods to measure vertebral rotation in adolescent idiopathic scoliosis. 总被引:3,自引:0,他引:3
A comparative analysis of two methods of measuring vertebral rotation in adolescent idiopathic scoliosis is reported in this article. Nash and Moe's pedicle shift method (using plain anteroposterior radiographs) is compared with a new method using computed tomographic scans. The computed tomographic scans of the whole length of the major curve and the scout films obtained from seventeen girls aged 12.5-14 years were measured for rotation of each vertebra of the curve (total number of vertebrae measured by two methods = 173). This study has three interesting new findings: 1) Those vertebrae with Nash & Moe grade 0 had up to 11 degrees of vertebral rotation when measured using the computed tomographic method. Therefore, Nash & Moe's grade '0' is not a neutrally rotated vertebra; 2) For Nash & Moe grade 1 and 2, the computed tomographic method revealed statistically significantly greater rotation for lumbar vertebrae than thoracic vertebrae. There was a similar pattern for Nash & Moe grade 0 but these differences were not statistically significant; and 3) Simple formulae are reported to convert Nash & Moe's grades into angle of vertebral rotation as obtained by CT method separately for thoracic and lumbar vertebrae. 相似文献

BACKGROUND: Our hypothesis was that abdominal and pelvic computed tomographic (AP-CT) scans are equivalent to portable two-view plain films in detecting lumbar spine fractures in adults. Since many trauma patients often undergo AP-CT scanning to evaluate for possible intra-abdominal injuries, using the AP-CT scan to screen for lumbar fractures could make the trauma evaluation process more efficient. METHODS: The institutional trauma registry at a Level I trauma center was used to identify all blunt lumbar fractures during a 6-year period. Medical records were reviewed. RESULTS: A total of 7,216 adult blunt trauma patients were evaluated, and 115 patients were identified as having a lumbar fracture, for an incidence rate of 1.6%. Missed fracture rates were high for both AP-CT scans (23.2%, 13 of 56) and portable two-view films (12.7%, 14 of 110, = 0.08). Fifty-two patients had both AP-CT scans and plain films. In this group, AP-CT scans missed 23.1% (12 of 52) of the lumbar fractures and plain films missed 15.4% (8 of 52). However, the combination of the two diagnostic methods did not miss any fractures (0 of 52). The missed fractures required surgery or brace in 50% (7 of 14) patients who had fractures missed by plain films and 46% (6 of 13) patients whose fractures were missed by AP-CT scanning. CONCLUSION: Both AP-CT scans and plain films failed to diagnose significant lumbar fractures that required therapy. When screening for lumbar fractures, obtaining both AP-CT scans and portable two-view plain films may decrease missed lumbar fractures in blunt adult trauma. 相似文献

Background:
To investigate false negative rate in the diagnosis of diastasis on initial static anteroposterior radiograph and reliability of intraoperative external rotational stress test for detection of concealed disruption of syndesmosis in pronation external rotation (PER) stage IV (Lauge-Hansen) ankle fractures.Materials and Methods:
We prospectively studied 34 PER stage IV ankle fractures between September 2001 and September 2008. Twenty (59%) patients show syndesmotic injury on initial anteroposterior radiographs. We performed an intraoperative external rotation stress test in other 14 patients with suspicious PER stage IV ankle fractures, which showed no defined syndesmotic injury on anteroposterior radiographs inspite of a medial malleolar fracture, an oblique fibular fracture above the syndesmosis and fracture of the posterior tubercle of the tibia.Results:
All 14 fractures showed different degrees of tibiofibular clear space (TFCS) and tibiofibular overlapping (TFO) on the external rotation stress test radiograph compared to the initial plain anteroposterior radiograph. It is important to understand the fracture pattern characterstic of PER stage IV ankle fractures even though it appears normal on anteroposterior radiographs, it is to be confirmed for the concealed syndesmotic injury through a routine intraoperative external rotational stress radiograph. 相似文献15.

Objective: To introduce a novel technique in which meniscal stitching needle is used as a puller to induct steel wire to secure the tibial eminence avulsion under arthroscopic visualization, and evaluate the cfinical results.
Methods: From 1999 to 2005, fifteen cases of tibial eminence avulsion were treated with this new technique. Lysholm scoring scale system was used to assess knee function before and after surgery. Regular plain anteroposterior and lateral X-ray flms were undertaken to detect the bony healing of avulsed fragment.
Results: The operating time could be controlled within 30 minutes. No complications such as intraarticular infection, iatrogenic injury, fibroarthritis or nonunion of fracture occurred in this group. X-ray film revealed that bony healing in all 15 cases was achieved from 6 weeks to 12 weeks postoperatively. Lysholm score was improved from 19.1 ± 15.2 ( ranging from 10 to 56 ) preoperatively to 97.5 ± 3.7 (ranging from 91 to 100) postoperatively on average in 12-54 months follow up (mean 23 months). The statistically significant difference was shown in Student's t test (t = 18. 483, P =3. 100×10^-11, P 〈 0. 01). Wire breakage was found in two patients whose wires were removed 8 months and 14 months after initial operation, respectively.
Conclusion: This technique has many advantages, such as simplicity, wide indications from type Ⅱ to type Ⅳ fractures, minimal invasion, short operating time and predictable satisfactory results. 相似文献

BACKGROUND CONTEXT: Several studies report a favorable short-term outcome after nonoperatively treated two-column thoracic or lumbar burst fractures in patients without neurological deficits. Few reports have described the long-term clinical and radiological outcome after these fractures, and none have, to our knowledge, specifically evaluated the long-term outcome of the discs adjacent to the fractured vertebra, often damaged at injury and possibly at an increased risk of height reduction and degeneration with subsequent chronic back pain. PURPOSE: To evaluate the long-term clinical and radiological outcome after nonoperatively treated thoracic or lumbar burst fractures in adults, with special attention to posttraumatic radiological disc height reduction. STUDY DESIGN: Case series. PATIENT SAMPLE: Sixteen men with a mean age of 31 years (range, 19-44) and 11 women with a mean age of 40 years (range, 23-61) had sustained a thoracic or lumbar burst fracture during the years 1965 to 1973. Four had sustained a burst fracture Denis type A, 18 a Denis type B, 1 a Denis type C, and 4 a Denis type E. Seven of these patients had neurological deficits at injury, all retrospectively classified as Frankel D. OUTCOME MEASURES: The clinical outcome was evaluated subjectively with Oswestry score and questions regarding work capacity and objectively with the Frankel scale. The radiological outcome was evaluated with measurements of local kyphosis over the fractured segment, ratios of anterior and posterior vertebral body heights, adjacent disc heights, pedicle widths, sagittal width of the spinal canal, and lateral and anteroposterior displacement. METHODS: From the radiographical archives of an emergency hospital, all patients with a nonoperatively treated thoracic or lumbar burst fracture during the years 1965 to 1973 were registered. The fracture type, localization, primary treatment, and outcome were evaluated from the old radiographs, referrals, and reports. Twenty-seven individuals were clinically and radiologically evaluated a mean of 27 years (range, 23-41) after the injury. RESULTS: At follow-up, 21 former patients reported no or minimal back pain or disability (Oswestry Score mean 4; range, 0-16), whereas 6 former patients (of whom 3 were classified as Frankel D at baseline) reported moderate or severe disability (Oswestry Score mean 39; range, 26-54). Six former patients were classified as Frankel D, and the rest as Frankel E. Local kyphosis had increased by a mean of 3 degrees (p<.05), whereas the discs adjacent to the fractured vertebrae remained unchanged in height during the follow-up. CONCLUSIONS: Nonoperatively treated burst fractures of the thoracic or lumbar spine in adults with or without minor neurological deficits have a predominantly favorable long-term outcome, and there seems to be no increased risk for subsequent disc height reduction in the adjacent discs. 相似文献

Hallux valgus is a complex deformity of the first ray and forefoot that can be surgically treated using different procedures and osteotomies. Preoperative planning includes anteroposterior and lateral plain films. The effect of weight-bearing on the results of the standardized measurements is still the subject of debate. We evaluated the effect of weight-bearing on the results of measurements and decision making by expert evaluators. A total of 21 foot and ankle surgeons were given weight-bearing and non-weight-bearing anteroposterior plain foot films of patients with hallux valgus. They were asked to measure 3 standard angles and then to select the most appropriate procedure from a short list. Using a paired Student's t test, no difference in the angles measured nor in the procedures chosen was detected between the weight-bearing and non-weight-bearing films. Although it is generally accepted that decisions regarding the treatment of hallux valgus should be based on plain weight-bearing films, in the present study, we established that non-weight-bearing films can reliably be used to choose the surgical procedure. 相似文献
