解剖型钢板治疗粉碎性尺骨鹰嘴骨折

目的 探讨解剖型钢板治疗粉碎性尺骨鹰嘴骨折的疗效.方法 2002年2月至2007年7月,共52例移位粉碎性尺骨鹰嘴骨折的患者,男37例,女15例,平均年龄37.6岁.按照Mayo分型:其中ⅡB型31例,ⅢB型21例.所有骨折均行切开复位解剖型钢板内固定.结果 术后49例获得随访,随访时间为12～20个月,平均14.2个月.所有骨折均于3个月内愈合,无伤口感染;3例由于钢板皮下激惹,取出内固定后症状缓解.术后采用Broderg和Money评分标准进行评估:30例ⅡB型骨折中优22例,良6例,可2例,差0例,优良率为93.3%;19例ⅢB型骨折中优6例,良8例,可4例,差1例,优良率为73.7%.两组疗效差别有统计学意义(P<0.05).结论 解剖型钢板是治疗粉碎性尺骨鹰嘴骨折的安全有效的方法,Mayo分型可作为判断骨折预后的依据.     

Unusual stress fracture in an adolescent baseball pitcher affecting the trochlear groove of the olecranon

Stress fractures of the proximal ulna are known to occur in throwing athletes. Most cases extend to involve the olecranon, and cases limited to the trochlear groove are rare. In this report we present a 17-year-old elite baseball pitcher with a stress fracture of the trochlear groove of the proximal ulna. Diagnosis was made by demonstration of characteristic signal changes on MRI of the elbow. The fracture occurred at the cortical notch, also known as the pseudodefect of the trochlear groove. This case suggests that the cortical notch serves as an area of weakness predisposing pitchers to development of a stress fracture.     

儿童陈旧性孟氏骨折不同手术方式的临床疗效探讨

目的探讨3种不同手术方式治疗陈旧性孟氏骨折的临床疗效。方法回顾性研究了2006至2012年,在我科接受手术的55例陈旧性孟氏骨折患者的病例。按Bado分型,I型33例,II型2例,III型20例。入院时,7例患儿有桡神经损伤症状。治疗前3组患者在年龄、性别、受伤时间、骨折类型、伴随神经损伤与否等临床资料方面,差异无统计学意义（P＞0.05）,具有可比性。根据入院后患者接受的手术方式将患者分为3组,其中A组：24例,行改良Hirayama尺骨截骨、掌长肌腱重建环状韧带术。B组：17例,行改良Hirayama尺骨截骨、克氏针固定肱桡关节术。C组：14例,行改良Hirayama尺骨截骨术。所有伴随桡神经损伤症状的患儿,均未给予特殊治疗。结果51例获得随访（随访率为92.7%）,A组23例,B组16例, C组12例,随访7～32个月,平均18.27个月。所有切口均一期愈合,骨折按期愈合,损伤的桡神经获得恢复。A组出现2例不良并发症（8.7%）：1例前臂旋转功能受限（旋前75°,旋后45°）,1例桡骨头半脱位;B组出现1例不良并发症（6.3%）：术后3周克氏针断裂;C组出现6例不良并发症（50.0%）：2例桡骨头半脱位,4例桡骨头全脱位。A组及B组不良反应发生率均少于C组,差异有统计学意义（P＜0.017）,A组不良反应发生率少于B组,差异无统计学意义（P＝1.000）。术后6个月,A组患者肘关节MEPI积分较术前平均增加30分,高于B组16.3分（P＝0.000）及C组24.4分（P＝0.048）,差异均有统计学意义,B组患者MEPI积分较术前平均增加16.3分,低于C组24.4分（P＝0.001）,差异均有统计学意义。结论改良Hirayama尺骨截骨加掌长肌腱重建环状韧带术治疗儿童陈旧性孟氏骨折优于单纯行Hirayama尺骨截骨术及联合克氏针固定肱桡关节术。     

Juxtacortical osteoma of the ulna

 A case of juxtacortical osteoma of the ulna in a 47-year-old woman is presented. She had a dense bony mass on the ulna. Radiological examinations (plain radiography, computed tomography, magnetic resonance imaging) strongly suggested a rare case of juxtacortical osteoma of a long tubular bone. The differential diagnosis included parosteal osteosarcoma, melorheostosis, osteochondroma, end-stage juxtacortical myositis ossificans, and fibrous dysplasia protuberans. The tumor was excised totally for thorough pathological examination, which revealed it to be composed of lamellar bone, suggesting that the origin was periosteal.

CR与CT对尺骨冠突骨折应用价值比较

目的：探讨CR与CT对尺骨冠突骨折诊断价值及Negan‐Morrey分型法的应用价值。方法回顾性分析55例含尺骨冠突骨折的肘关节CR及CT图像,以临床诊断为金标准作为比对,分析CR与CT对肘关节任何部位骨折诊断准确率、肘关节骨折检出率、尺骨冠突骨折检出率及“Negan‐Morrey分型法”诊断灵敏度。结果55例肘关节骨折首诊C R准确诊断骨折33例,诊断不符22例,C R诊断准确率60％;C T 准确诊断54例,诊断不符1例,诊断准确率98．2％, CT对肘关节骨折诊断准确率优于MRCR（礸2＝24．24,P ＜0．05）。以“肘关节骨折中至少检出一处”为标准,CR检出41例,漏诊14例,检出率为74．55％,C T全部检出（100％）。MRC T对肘关节骨折检出率优于C R （礸2＝16．04, P ＜0．05）。仅对尺骨冠突骨折分析,C R检出37例,阴性18例,检出率67．27％,M RC T 全部检出（100％）。M RC T 对尺骨冠突骨折检出率优于C R （礸2＝21．52, P ＜0．05）。尺骨冠突骨折C R分型：I型19例,Ⅱ型12例,Ⅲ型6例,未分型18例;M RC T分型：I型26例,Ⅱ型14例,Ⅲ型14例,未分型1例。与临床分型比较,4例M RC T诊断为II型,而临床诊断为Ⅲ型,2例MRCT诊断为Ⅱ型,临床诊断为I型。尺骨冠突骨折MRCT分型敏感性高于CR（ P ＜0．05）。结论 CR对肘关节骨折具有较高的检出率,但诊断准确性不高,对尺骨冠突骨折检出率及骨折分型敏感性低于MRCT ;对CR诊断肘关节骨折尤其怀疑尺骨冠突骨折病例应行M RC T检查,对减少漏诊及指导临床制定合理的治疗方法意义重大。

Malignant primary intraosseus synovial sarcoma – a rare case report

Primary intraosseous synovial sarcoma is an extremely rare malignancy that occurs primarily in young adults. We present a case of a primary intraosseous synovial sarcoma of the right distal ulna in a 19-year-old female. It has a propensity to mimic other radiologic and pathologic diagnosis. Histopathology after a surgical excisional biopsy with a wide margin plus adjunct radio and chemotherapy are necessary to improve prognosis.     

尺骨冠状突骨折的手术治疗

目的探讨尺骨冠状突骨折的手术适应证、入路及内固定方法。方法自1998年1月～2005年1月手术治疗尺骨冠状突骨折患者23例(24侧)。Regan-Morrey分型:Ⅰ型1例,Ⅱ型15例(16侧),Ⅲ型7例。内固定方法:克氏针张力带钢丝及螺丝钉固定各6侧,克氏针加丝线固定3侧,单纯克氏针固定2侧,钢丝环扎固定1侧,骨片摘除5侧,冠状突重建1侧。结果对随访资料完整的20例(21侧)进行9～28个月(平均19个月)的随访,根据肘关节活动范围、疼痛程度、肌力,以及稳定性进行评定疗效:优9侧,良6侧,可3侧,差3侧,优良率71.4%。肘关节半脱位2例,骨化性肌炎2例,无肘关节脱位及肘关节强直等严重并发症。结论Ⅲ型骨折、明显移位及伴有肘关节不稳的Ⅱ型骨折宜采用手术治疗;手术不仅可以复位、固定骨折,同时也可修复或重建损伤的韧带,可早期行肘关节功能练习;正确的手术入路及内固定方法是提高疗效的关键。     

不同类型尺骨近端骨折的内固定选择和疗效分析

目的探讨不同类型尺骨近端骨折的临床特点、内固定选择、手术策略和临床疗效。 方法回顾性分析2014年6月至2017年6月收治的45例尺骨近端骨折患者资料，男26例、女19例；年龄19~65岁，平均40.8岁；致伤原因：摔伤25例，高处坠落伤12例，交通伤8例。所有患者均行手术治疗，根据骨折的特点和类型分别选择克氏针张力带、解剖钢板或两者联合的方法固定骨折，恢复骨性结构的稳定性。合并尺骨冠状突骨折采用袢钢板固定。合并桡骨头骨折采用微型钢板固定或金属桡骨头置换。合并韧带损伤时均采用带线锚钉缝合固定修补。 结果45例患者获15.6个月（12~24个月）随访。随访结果：所有患者均获骨性愈合，愈合时间平均为11.2周（8~16周）。末次随访：肘部屈曲活动80°~135°，平均121°；肘部伸直活动0~30°，平均8°。Mayo肘关节功能评分为50~100分，平均88.2分，其中优26例，良15例，可2例，差2例，优良率为91.1％。 结论尺骨近端骨折形态各异，应该根据受伤机制、骨折特点及患者情况进行骨折严重程度的评估和分型，选择合理的内固定方式，积极进行术后康复，恢复良好的肘关节功能。     

Melorheostosis of upper limb: A report of four rare cases

Melorheostosis is a rare chronic bone disease, etiology of which remains unclear. It mostly affects lower limbs and clinical features vary in each case. Radiographs show characteristic "candle wax pattern" of hyperostosis. Herein we report four cases of upper limb affection with their symptoms, radiographic findings and treatment. First case presented with gradually progressive swelling in forearm which was initially misdiagnosed as filariasis. Plain radiograph eventually demonstrated melorheostosis of ulna. Second patient had deformity of index finger and pain in hand which was diagnosed on radiograph of hand. Third case presented with progressive flexion deformity of ring and little finger. Fourth patient had ulnar involvement which was an incidental diagnosis. First three patients were managed with bisphosphonates following which there was significant improvement in pain and fourth case was kept on follow-up as he was asymptomatic.
