OE Journal. 2014;2(22):13 J Hand Surg Am. 2014 Sep;39(9):1692-879 women aged 40 years and older diagnosed with severe stage IV osteoarthritis (OA) were randomly assigned to undergo ligament reconstruction and tendon interposition (LRTI) of the basal thumb joint using either the Burton-Pellegrini (BP) or the Weilby technique. The BP technique uses a bone tunnel at the base of the thumb, while the Weilby technique does not. The purpose of this study was to compare the short- and long-term pain and physical function outcomes of both techniques. Findings suggested the BP technique prompted faster recovery than the Weilby technique, with better clinical outcome at 3 months. Outcome at 12 months was not significantly different between groups.

Fragility Indexは、重要な所見の解釈を助けるツールで、結果の強さの尺度を提供します。Fragility Indexは、その所見が有意でなくなるために、二項対立の結果に追加する必要がある連続した事象の数を表します。数値が小さいほど弱い所見を表し、数値が大きいほど強い所見を表します。
なぜ今この研究が必要なのですか？
Major impairment can ensue in patients suffering from osteoarthritis (OA) at the base of the thumb, particularly in patients with stage IV OA, due to further cartilage and ligament damage in addition to metacarpal subluxation. Ligament reconstruction and tendon interposition (LRTI) has been speculated to provide effective treatment of stage IV OA. Several techniques using different tendon grafts can be performed, such as the Burton-Pellegrini (BP) (bone tunnel) and the Weilby (without bone tunnel) techniques, but comparative studies are limited. This study aimed to compare pain, physical function, and complication outcomes between the two techniques.
主な研究課題は何ですか？
In the treatment of basal thumb osteoarthritis, how does arthroplasty with and without the use of a bone tunnel at the base of the first metacarpal compare in women with stage IV osteoarthritis at 12 months postoperative?
重要な知見は？
- Within-group comparisons of preoperative measurements at 3 and 12 months demonstrated significant improvement in both groups for PRWHE-pain (p<0.001), PRQHE-activities (p<0.001), PRWHE-total (p<0.001) and DASH (p<0.003).
- Patients in the bone tunnel group experienced significantly superior PRWHE-pain (p=0.02) and PRWHE-total (p=0.03) score compared with the no bone tunnel group, but PRWHE-activities (p=0.10) and DASH (p=0.08) did not differ significantly between groups at 3 months postoperative.
- Pain and physical function outcomes measured using PRWHE and DASH were not significantly different between groups at 12 months postoperative (p>0.05).
- Carpometacarpal extension was significantly superior in the no bone tunnel group than the bone tunnel group at 12 months postoperative (p=0.001).
- All other range of motion measurements, grip strength, complications, patient satisfaction, time to return to work/activities, and proximal migration outcomes did not differ significantly between groups at 3 and 12 months postoperative (all p>0.05).
最も覚えておくべきことは？
Pain and physical function outcomes were significantly improved at 3 and 12 months postoperative regardless of arthroplasty technique, however patients in the bone tunnel group achieved significantly superior PRWHE-pain and PRWHE-total scores than patients in the no bone tunnel group at 3 months postoperatively. The no bone tunnel group experienced significantly greater carpometacarpal extension compared with the bone tunnel group at 12 months postoperatively.
それが私の患者ケアにどのように影響するか？
Results from this study indicate a preference towards the Burton-Pellegrini (bone tunnel) technique to the Wieilby technique (no bone tunnel) in the treatment of stage IV osteoarthritis because of its superior pain and physical function outcomes in the short term, suggesting faster recovery can be achieved with the use of a bone tunnel. This study included a relatively homogeneous study group of women with IV osteoarthritis, so these results should not be assumed for the male population or less severe grades of osteoarthritis.
