目的 探讨采用手术切开复位与手法复位石膏外固定的非手术疗法对桡骨远端骨折患者腕关节功能恢复的影响。方法 选取本院骨科收治的97例桡骨远端骨折患者进行回顾性分析,其中采取切开复位内固定手术治疗53例(手术组)、采取手法复位石膏外固定治疗44例(非手术组),对比两组患者的腕关节功能恢复情况。结果 手术组的骨折愈合时间平均为(5.8±1.1)周,非手术组为(6.0±0.8)周,两组患者的骨折愈合时间差异无统计学意义(P>0.05)。术后3个月,手术组和非手术组患者的腕关节背伸、腕关节曲度、尺偏角、桡偏角、尺骨移位测定值差异无统计学意义(P>0.05),手术组的掌倾角、握力、桡骨高度测定值优于非手术组(P<0.05);术后6个月,两组患者腕关节背伸、腕关节曲度、尺偏角、桡偏角、掌倾角、握力、桡骨高度、尺骨移位测定值差异均无统计学意义(P>0.05);术后6个月,手术组的腕关节功能优良率96.2%与非手术组患者的90.9%差异无统计学意义(P>0.05)。结论 对于OTA分级相当的患者,采用手术切开复位内固定有利于患者腕关节功能的早期恢复,但是远期恢复效果手术与非手术治疗差异并不显著。 相似文献

Fractures involving the fetlock region are encountered commonly in Thoroughbred racehorses. Condylar fractures of the distal metacarpus/metatarsus and mid‐sagittal fractures of the proximal phalanx account for the majority of fetlock injuries during both racing and training and clinical features, management and outcome of these injuries have been well described. Transverse fractures of the distal diaphysis of the third metacarpus, however, are seldom observed and have received little attention in the literature. This paper describes clinical and radiological findings associated with 6 cases encountered in first opinion racehorse practice over a 3 year period. Transverse third metacarpal fractures vary in presentation but typically have clinical signs referable to the fetlock region and may, on occasion, be life‐threatening. They are therefore an important differential diagnosis when a fracture involving the fetlock is suspected. 相似文献

通过宏观检验观察、化学成分分析、硬度测试、金相检验和断口分析等方法对弹簧垫圈的断裂原因进行分析。结果表明:该弹簧垫圈热处理时产生淬火裂纹,镀锌时氢原子在裂纹尖端偏聚,这两种因素的共同作用导致弹簧垫圈在装配预紧过程中发生脆性断裂。 相似文献

Objective
To test the efficacy of intraoperative intrafragmentary administration of bupivacaine (haematoma block) in controlling postoperative pain in dogs undergoing osteosynthesis of long-bone isolated diaphyseal fractures.Study design
Randomized, ‘blinded’, placebo-controlled, prospective study.Animals
A total of 23 client-owned dogs with isolated long-bone fractures.Methods
Dogs were allocated randomly to two groups: bupivacaine group (B) or placebo group (P). Group B dogs (n = 11) were administered an intraoperative intrafragmentary injection of 0.5% bupivacaine (1.1 mg kg–1) just before fracture fixation, whereas group P dogs (n = 12) were administered normal saline. Postoperative pain evaluations using the University of Melbourne Pain Scale (UMPS) and algometer were performed upon arrival to the recovery room and 1, 2, 4, 6, 8, 20 and 32 hours later. Algometer measurements were performed on: the incision site, a healthy region near the fracture line and the contralateral healthy limb. When the pain score exceeded 14 points in the UMPS, rescue analgesia was administered. The time-standardised area under the curve (AUCst) was used to compare UMPS scores and mechanical pain thresholds between the two groups.Results
None of the group B dogs required rescue analgesia, whereas eight of the 12 group P dogs did (p = 0.001). The pain threshold AUCst at the incision line was higher in group B [16.3 (2.9–41.6) N] than in group P [5.6 (2.5–17.4) N] (p = 0.029). The mean UMPS score AUCst was lower in group B (3.7 ± 1.8) than in group P (9.4 ± 4.6) (p = 0.016). In a small number of animals of both groups that were evaluated radiologically, adequate bone healing was noted.Conclusions and clinical relevance
An intraoperative bupivacaine haematoma block is a simple, quick and effective method that can be used to aid in postoperative pain control in dogs submitted to long-bone osteosynthesis. 相似文献77.

Fixation of a complete scapular neck fracture in a foal using two 3.5 mm locking compression plates 下载免费PDF全文
This report describes the successful surgical repair of a transverse, displaced scapula fracture in a foal. A 3.5 mm locking compression plate (LCP) was used on either side of the spine of the scapula. The suprascapular nerve was apparent upon dissection as it passed directly over the fracture line and care was taken to leave it intact, although the fracture line itself caused some irritation. The foal recovered without long‐term nerve damage and is sound at 1.5 years post surgery. 相似文献

Distal phalanx fractures are well documented in adult horses, but our knowledge of such fractures in foals is limited. Recent studies showed a high incidence of distal phalanx palmar process (PP) fractures in foals, the aetiology is not yet known. Several hypotheses have been suggested as possible causes, including uneven compressive forces, unequal forces from the deep digital flexor tendon, composition and shape of the PP, and conformation. A better understanding of the aetiology and predisposing factors requires further research. Radiography is the commonly used imaging modality for diagnosis of such fractures; however, those fractures might be missed on routine radiographic projections. In order to have a high probability of identifying fractures, a series of 5 radiographs including the oblique views is required. This article reviews the incidence of distal phalanx PP fractures and discusses the diagnosis of such fractures. 相似文献

竹材Ⅲ型层间的断裂韧性 总被引:1,自引:0,他引:1
采用改进设计的端部切口悬臂梁(SCB)装置,试验测试毛竹(Phyllostachs pubescens)Ⅲ型层间断裂性质,并分别用柔度法和面积法计算其Ⅲ型层间断裂韧性值。结果表明:(1)采用柔度法和面积法得到的Ⅲ型层间断裂韧性,分别为2.38 N·m~(-1)(标准差0.74 N·m~(-1))、2.20 N·m~(-1)(标准差0.36 N·m~(-1)),前者略高于后者,但方差分析差异不显著;(2)二种方法测得的Ⅲ型层间断裂韧性,基本上与裂纹尺寸无关,说明层间断裂韧性是竹材的一种基本性质;(3)对竹材断面的观察发现,Ⅲ型层间裂纹在未木质化的短型基本组织细胞中的扩展是伴随着胞壁的撕裂,但在已木质化的长型基本组织细胞之间和纤维束之间,裂纹是沿胞间层扩展的。 相似文献
