Abstract
目的 探讨初次人工全髋关节置换术(THA)后早期股骨假体周围骨折的治疗方法及疗效.方法 2006年5月至2010年9月共收治15例初次THA后早期股骨假体周围骨折患者,男6例,女9例;年龄为63 ～ 82岁,平均72.3岁.骨折距THA时间平均为62.5 d(3～87 d).骨折类型按Van-couver分型:AG型2例,AL型2例;B1型5例,B2型3例,B3型1例;C型2例.非手术治疗2例,手术治疗13例:切开钢丝环扎内固定2例,记忆合金环抱器固定3例,长柄生物型假体翻修术4例,锁定加压钢板内固定4例.记录患者的骨折愈合时间,比较患者术前与术后1年的疼痛视觉模拟评分(VAS)和髋关节Harris评分. 结果 15例患者术后获平均3.5年(1.5 ～5.0年)随访.12例患者于术后平均4.5个月(3.5 ～9.0个月)获骨性愈合,愈合率为80％.术后1年15例患者的疼痛VAS评分由术前平均(7.4+1.2)分降低至(2.3+1.1)分,髋关节Harris评分由术前平均(35.1+5.4)分提升至(75.4+7.2)分,术前与术后1年比较差异均有统计学意义(P＜0.05).3例患者出现骨折延迟愈合.3例患者发生骨折不愈合,其中1例合并感染,均采取二期手术治疗.结论 对于初次THA后早期股骨假体周围骨折,根据不同Vancouver分型选择记忆合金环抱器、锁定钢板或假体翻修术治疗可取得满意疗效。

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; both teacher heads agree on what is shown here.
