Coatings for femoral stems .
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2013;1(2):23 Acta Orthop. 2011 Jun;82(3):308-14. Epub 2011 Apr 1950 arthritic patients undergoing total hip arthroplasty were randomized to receive either distally tapered, extended coated stems, or straight proximally coated stems, to study potential differences in implant migration. At 2 years post-surgery, radiostereometric analysis revealed that both stem types demonstrated large amounts of implant migration, with no significant differences between groups.
Was the allocation sequence adequately generated?
Was allocation adequately concealed?
Blinding Treatment Providers: Was knowledge of the allocated interventions adequately prevented?
Blinding Outcome Assessors: Was knowledge of the allocated interventions adequately prevented?
Blinding Patients: Was knowledge of the allocated interventions adequately prevented?
Was loss to follow-up (missing outcome data) infrequent?
Are reports of the study free of suggestion of selective outcome reporting?
Were outcomes objective, patient-important and assessed in a manner to limit bias (ie. duplicate assessors, Independent assessors)?
Was the sample size sufficiently large to assure a balance of prognosis and sufficiently large number of outcome events?
Was investigator expertise/experience with both treatment and control techniques likely the same (ie.were criteria for surgeon participation/expertise provided)?

مؤشر الهشاشة هو أداة تساعد في تفسير النتائج المهمة، وتوفر مقياسًا لقوة النتيجة. ويمثل مؤشر الهشاشة عدد الأحداث المتتالية التي يجب إضافتها إلى نتيجة ثنائية التفرع لجعل النتيجة غير مهمة. يمثل الرقم الصغير نتيجة أضعف ويمثل الرقم الكبير نتيجة أقوى.
لماذا كانت هناك حاجة لهذه الدراسة الآن؟
The varying types of femoral stem coatings used for total hip arthroplasty have been investigated in studies to determine implant migration and rotation. This study aims to further investigate the outcomes with respect to extended coating versus proximal coating.
ما هو سؤال البحث الرئيسي؟
Does an extended coated stem lead to reduced implant migration two years postoperatively, when compared to a proximally coated stem in patients undergoing total hip arthroplasty for primary osteoarthritis?
- no statistically significant difference during RSA assessment with respect to rotation or translation detected between groups at any of the follow-up points
- implant migration of both groups was significant from initial postoperative measurements
ما الذي يجب أن أتذكره أكثر؟
Both implant stem groups demonstrated significant migration in comparison to baseline measures; however, no statistically significant difference was detected between the groups. The authors recommend that additional follow-ups are required in future trials.
كيف سيؤثر ذلك على رعاية مرضاي؟
Both implants demonstrate significant migration,which warrants further investigation; however, this trial was unable to conclude which coating is superior. Additionally, the authors cite this study as an evidence for the necessity of RSA, as standard protocol to monitor all new implants.
