肩胛盂骨折的手术治疗

目的探讨肩胛盂骨折的分型、手术治疗指征和方法。方法对8例肩胛盂骨折手术治疗患者临床资料进行分析,根据改良Idebery肩胛盂骨折分型:Ⅰ型3例,Ⅱ型1例,Ⅲ型2例,Ⅴ型2例。分别采用切开复位重建钢板和拉力螺钉固定。结果患者均获随访,时间6~41个月,平均14.2个月。根据美国肩肘协会评分标准进行肩关节功能评分,为55~100分,平均85.6分,优5例,良1例,可1例,差1例。结论肩胛骨盂缘骨折块移位≥1 cm、前缘骨折块≥25%、后缘骨折块≥33%,或盂窝骨折肩关节面不平整≥5 mm及盂肱关节不稳定均需手术治疗。对肩胛盂骨折采用改良Idebery分型,有利于指导临床手术治疗,且手术疗效满意。     

Optimal glenoid fixation requires cement!

The choice of cemented versus uncemented glenoid component fixation has generated controversy, but the evidence favors cement. Studies have shown survivorship of cemented all-polyethylene glenoid components of 95% at 10 years and still over 90% at 15 years. Virtually all glenoid with stiff metal backing, especially those that snap-fit to assemble, have had poor results even at early follow-up. Recent designs with either all-polyethylene cementless fixation or using a less-stiff, integrated tantalum backing have promising early results.     

Managing glenoid bone loss virtual surgery—A software solution

Inaccurate placement of glenoid prosthesis in shoulder arthroplasty can lead to early loosening, instability, and failure. To address difficult glenoid morphology, patient-specific instrumentation and navigation techniques have been developed. Advanced imaging data has demonstrated utility in preoperative decision making. Cadaveric studies have subsequently shown that the application of advancing imaging and navigation can lead towards increased accuracy with prosthesis placement. Clinical trials have also shown increased accuracy with navigation and advanced imaging, but data demonstrating improved long-term outcomes and decreased complication rates is not yet available. This technology continues to evolve as a method to address glenoid bone loss and abnormal morphology.     

肩胛盂骨折的手术治疗

目的探讨手术治疗肩胛盂骨折的疗效。方法对12例肩胛盂骨折患者采用切开复位螺钉和重建钢板内固定治疗。结果患者均获随访,时间6～25个月。骨折全部愈合,愈合时间6～11周。末次随访时肩关节外展60°～170°(135°±5.6°)。根据Herscvici肩关节功能评分标准:优2例,良8例,可2例。结论手术治疗肩胛盂骨折可以获得较好的临床效果。
