创伤引发的股骨颈骨折是临床上常见的骨科疾病之一,而其后续发生的以股骨头缺血坏死为代表的并发症是导致患者出现下肢运动功能障碍的主要原因之一。目前对于创伤后股骨颈骨折具体的损伤及修复机制仍不甚明了,因此研究股骨颈骨折后患者身体的各项指标及临床上针对的治疗措施对预后产生的影响,可为预测股骨颈骨折患者未来的预后打好基础,并为采取相应的干预手段提供思路。目前主要认为创伤后股骨颈血供不足和相关炎性重建反应是创伤性股骨头坏死的主要作用机制,而作用于相关机制的因素则被认为是其可能的危险因素。本文整理了近年来对于股骨颈骨折后续发生坏死相关影响因素的报道。学界主要认为受伤原因、Garden分型等骨折分型方式、内固定方式及复位质量等因素被认为是导致预后不良的可能危险因素。  相似文献

文题释义:股骨颈骨折复位内固定:股骨颈骨折是临床最为常见的一种骨折类型,约占全部髋部骨折的50%。空心钉内固定依然是临床上治疗股骨颈骨折最常用的方式,且取得了较满意的临床疗效,术后股骨头坏死和骨折不愈合的发生率呈明显下降趋势。 股骨颈短缩:空心钉内固定治疗后,部分患者术后可能出现股骨颈短缩的现象,甚至造成患者术后髋关节功能障碍的发生。 背景:空心钉内固定目前是临床上治疗股骨颈骨折最常用的方式,但部分患者术后可能出现股骨颈短缩的现象,甚至造成患者术后髋关节功能障碍的发生。 目的:探讨股骨颈骨折复位内固定后股骨颈短缩的发生率、临床特点、预后转归及相关影响因素。 方法:回顾性收集2012年1月至2017年3月成都地区3家骨科医院采用空心钉内固定治疗并获得完整术后随访信息的111例股骨颈骨折患者作为研究对象,所有患者对治疗方案均知情同意,且得到医院伦理委员会批准。以术后股骨颈短缩作为预后观察指标,记录患者股骨颈短缩的发生率、发生时间及主要临床特点;采用单因素卡方检验分析性别、年龄、Garden分型、Garden指数、骨密度T值、Singh指数、受伤至手术时间、负重时间等因素与术后股骨颈短缩的相关关系,再将有统计学意义的因素纳入多因素Logistic回归模型分析。 结果与结论:①股骨颈短缩发生率为48.6%(54/111),其中股骨颈短缩10-19 mm的发生率为31.5%(35/111)、股骨颈短缩≥20 mm的发生率为5.4%(6/111);②股骨颈短缩的发生时间主要集中在术后6个月内,占76%;③股骨颈短缩的临床症状主要包括下地负重时疼痛、髋关节活动受限和跛行,股骨颈短缩的临床表现分析结果显示,颈短缩组以中度疼痛为主(67%),无短缩组以无疼痛/轻度疼痛为主(86%);颈短缩组髋关节活动受限的发生率高于无短缩组(68% vs. 21%),颈短缩组患者跛行的发生率高于无短缩组(61% vs. 18%),差异均有显著性意义(P均< 0.05);④单因素及多因素Logistic回归模型分析表明,骨折Garden分型为Ⅲ,Ⅳ型、Garden指数为Ⅲ,Ⅳ级、骨密度T值≤-2.5、负重时间≤2个月是股骨颈骨折复位内固定后发生股骨颈短缩的独立危险因素,说明股骨颈骨折空心钉内固定后存在很高的股骨颈短缩发生风险,而发生时间主要集中术后6个月内。 ORCID: 0000-0002-4430-4394(牟帅) 中国组织工程研究杂志出版内容重点:人工关节;骨植入物;脊柱;骨折;内固定;数字化骨科;组织工程  相似文献

Head and neck rhabdomyosarcoma (HNRMS) is exceedingly rare and poorly documented. The difficult diagnosis often causes a poor prognosis and high mortality. Hence, we report 4 cases of HNRMS and their follow-up outcomes, and review the clinicopathological features of this rare tumor. The 4 patients ranged in age from 5 to 29 years. Among them, 3 patients had a good prognosis after combination of radiotherapy and chemotherapy or surgery alone. Another patient survived for only 3 months after diagnosis without therapy. Deeply insight into HNRMS might improve the ability of diagnosis and treatment for this disease.  相似文献

Pleomorphic lipoma is a rare lipocytic neoplasm that most commonly occurs in the head and neck region in middle‐aged to elderly men. Clinically, it presents as a slow‐growing, wellcircumscribed subcutaneous mass. Histopathologically and cytogenetically, it has some features overlapping with other benign and malignant tumors, such as benign spindle cell lipoma, atypical lipomatous tumor, liposarcoma, and malignant fibrous histiocytoma. However, cure rates are high when pleomorphic lipoma is treated with complete surgical excision with clear margins. Therefore, an accurate preoperative diagnosis is very important for proper treatment. Due to the rarity of this tumor, few cases diagnosed by cytology have been reported in the English literature. Here, we report two cases of pleomorphic lipoma, the diagnoses of which were suggested on fine needle aspiration biopsies and subsequently confirmed by surgical excisions. Diagn.

Morphometric parameters of the radial neck: an anatomical study   总被引:2,自引:2,他引:0  
Introduction The purpose of this study was to describe the anatomy of the intramedullary canal of the radial neck for stem design of radial head prostheses. Methods Radial neck measurement was performed from the proximal edge of the radial tuberosity to the distal border of the articular surface on 40 macerated proximal radii using X-rays and Optosil imprints of the intramedullary canal. Radial neck to shaft angle was measured under image intensification. Results The neck length was 13.3 mm (range 8.0–20.0 mm) measured on X-rays and 13.5 mm (range 9.9–18.8 mm) on Optosil imprints. Concerning the neck’s intramedullary canal we obtained a minimum diameter of 9.7 mm (range 6.3–16.4 mm) on X-ray. Corresponding Optosil imprints had a mean diameter of 11.6 mm (range 6.6–18.6 mm) at their proximal end, 10.5 mm (range 5.5–16.3 mm) in the middle and a minimum of 9.8 mm (range 6.0–16.9 mm) at the distal end. Differences between left and right sides were not significant between X-ray and Optosil imprints, nor between left X-ray and right imprints and vice versa at a P-level of 0.001. Radial neck to shaft angle was 167.8° (range 160.5–178°) measured under image intensification at a rotation angle of 58.6° (range 50–70°) supination. Conclusion Geometry of the radial neck’s intramedullary canal has been described for stem design. The minimum diameter was seen at the distal end, just proximal to the radial tuberosity. A forearm rotation of 58.6° to full supination should be considered during implantation of monopolar prostheses. The wide variety of lengths and diameters complicates standard prosthetic design, but ipsilateral and contralateral X-rays can be useful for preoperative stem size calculation.  相似文献

Rosai-Dorfman disease (RDD) is a benign, rare histiocytic disorder presenting as a wide clinical spectrum, which mainly affects bilateral dilated lymph node enlargement. This study aimed to show an infantile RDD and review the clinicopathologic features, imaging, and histological features of RDD, including pitfalls in diagnosis. We report here an infant who had a 3-month history of painless bilateral cervical masses progressed to tracheal compression. Postoperative immunohistochemical results with positive characteristic staining of CD68 and S-100, negative for CD1a, which helped to determine the diagnosis. This peculiar case is the youngest case of RDD presenting with painless massive lymph node progressing to severe dyspnea due to tracheal compression. The optimal treatment still remains challenging. Future research should focus more on etiology and pathogenesis of RDD, especially relapsing cases.  相似文献

AIMS: To report three cases of primary carcinoma of the neck arising in multilocular thymic cysts (MTC). METHODS AND RESULTS: The patients were three men aged 47, 50 and 52 years who presented with a painless neck mass of several weeks' duration. The patients had no history of previous surgical procedures or of malignancy elsewhere. The tumours in all three patients were located on the right lateral side of the neck; all patients underwent complete surgical resection of the mass. Grossly, the tumours were cystic and measured between 20 and 30 mm in greatest diameter. Histologically, the tumours showed cyst walls lined by squamous epithelium. The cyst walls contained prominent germinal centres with lymphoid hyperplasia, cholesterol cleft granulomas, and scattered keratinized structures reminiscent of Hassall's corpuscles. In addition, a neoplastic cellular proliferation composed of round to oval cells arranged in sheets and originating from the lining of the cystic structures was present. The neoplastic cells showed moderate amounts of eosinophilic cytoplasm, round nuclei, and, in some areas, prominent nucleoli. Mitotic figures were easily found, and cellular pleomorphism was present in several areas. In two cases the tumours showed features of basaloid carcinoma of the thymus, while in one case the pattern was that of squamous cell carcinoma. Immunohistochemical studies for keratin showed a strong positive reaction in the tumour cells, while leucocyte common antigen strongly stained the lymphoid background. Follow-up information obtained in two patients showed them to be alive 6 months after initial diagnosis. One patient was lost to follow-up. CONCLUSION: The cases described here represent an unusual variant of carcinoma arising in multilocular thymic cyst in the neck region.  相似文献

艾滋病合并马尔尼菲青霉病2例诊断分析   总被引:4,自引:1,他引:3  
目的 提高艾滋病合并马尔尼菲青霉病的诊断率。方法 分析2例明确诊断为艾滋病合并马尔尼菲青霉病病例的临床及病理资料并复习相关文献。结果 艾滋病合并马尔尼菲青霉病以“发热、淋巴结肿大、肺部阴影”为主要临床表现;淋巴结病变主要为“淋巴细胞显著减少,淋巴结内组织细胞增生并见大量类圆形病原体,少数为腊肠状病原体,偶见横膈,胞质嗜酸性,核弱碱性。结论 HIV主要破坏CD4阳性T细胞,导致机体免疫功能下降而感染马尔尼菲青霉菌;马尔尼菲青霉病又成为艾滋病的表征之一。因此,有发热、咳嗽、淋巴结肿大、淋巴细胞数减少、双肺部阴影的患者要考虑艾滋病合并马尔尼菲青霉病感染的可能。  相似文献

We describe the cytomorphology of seven cases of metaplastic carcinoma of the breast studied by fine-needle aspiration cytology and by histology. All seven cases contained foci of ductual adenocarcinoma. This finding was combined with heterologous mesenchymal elements in four cases, a spindle-cell pattern of growth in one case, and extensive squamous-cell metaplasia in two cases. Both carcinomatous and metaplastic components were present on smears in four cases (57%). Thus in three cases (43%), the diagnosis was not possible on smear material alone. Differential diagnostic considerations are discussed.  相似文献

A total of 135 pediatric head and neck tumors diagnosed in our institute were reviewed with a view to elucidate the overall cytological patterns and analyze the important cytological features. Ninety-four tumors (69.6%) were aspirated for a primary diagnosis, and in 41 (30.4%) cases, fine-needle aspiration cytology was performed to document relapse, recurrence or a metastasis. Among the 94 tumors aspirated for a primary diagnosis, 66 cases (70.2%) were accurately diagnosed, in 22 cases (23.4%) a broad working diagnosis was offered, and 6 cases (6.4%) were misdiagnosed. The accuracy rate was higher (79.3%) when relapse-recurrent and metastatic tumors were included. The smears were broadly divided into six patterns, viz. round cell, epithelial, anaplastic, giant cell, mixed inflammatory, and spindle cell patterns. The round cell pattern was the most frequent one encountered in this group. The cytological features that stood the test of variability were lymphoglandular bodies and a noncohesive cell population in hematolymphoid malignancies, pale chromatin and cytoplasmic vacuoles in primitive neuroectodermal tumor/Ewing's sarcoma (PNET/ES), neuropil and rosettes in neuroblastoma, and plasmacytoid rhabdomyoblasts in rhabdomyosarcoma. A fairly good accuracy was seen in the diagnosis of metastatic undifferentiated carcinoma and anaplastic lymphoma, but the giant-cell and spindle-cell tumors continued to pose a problem in diagnosis. Ancillary techniques such as immunocytochemistry and electron microscopy applied in limited cases helped evaluate Langerhans cell histiocytosis, alveolar rhabdomyosarcoma, and the PNET/ES family of tumors.  相似文献
