Ultrasound versus Palpation-Guided Injection of Corticosteroid for Plantar Fasciitis: A Meta-Analysis
OrthoEvidence Journal (OE Journal) - ACE Report
OE Journal. 2014;2(10):13 PLoS One. 2014 Mar 21;9(3):e92671. doi: 10.1371/journal.pone.0092671. eCollection 20145 randomized control trials containing 149 patients were analyzed in this meta-analysis to determine the efficacy of ultrasound versus palpation-guided corticosteroid injections for plantar fasciitis. Patients who received ultrasound-guided corticosteroid injections had a higher tenderness threshold, thinner plantar fascial thickness, and a lower incidence of hypoechogenicity compared to palpation-guided corticosteroid injections. Other outcomes including pain, the heel tenderness index, response rate, and heel pad thickness were 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？
Approximately 80% of all heel pain in adult patients is caused by plantar fasciitis. Conservative treatments for plantar fasciitis include rest, nonsteroidal anti-inflammatory drugs, stretching, physical therapy, and foot padding. If these fail, patients tend to seek corticosteroid injections as an alternative treatment option. Various randomized control trials have compared ultrasound and palpation-guided corticosteroid injection for the treatment of plantar fasciitis, but the results are conflicting. Therefore, this meta-analysis was needed to determine the efficacy of ultrasound- versus palpation-guided corticosteroid injections.
主な研究課題は何ですか？
Is the efficacy of ultrasound-guided corticosteroid injections superior to palpation-guided corticosteroid injections for the treatment of plantar fasciitis?
重要な知見は？
- All 5 RCTs in this meta-analysis reported VAS pain, and found pain was not significantly different between ultrasound-guided and palpation-guided corticosteroid injections (SMD= -0.35, 95%CI (-0.83, 0.14), p=0.16).
- 2 studies reported that ultrasound-guided injections result in a higher tenderness threshold than palpation-guided injections (MD=2.17, 95%CI (1.28, 3.06), p=0.00).
- 2 studies reported the heel tenderness index did not differ significantly between ultrasound- and palpation-guided injections (MD= -0.25, 95%CI (-0.63, 0.13), p=0.20).
- 3 studies (93 patients) revealed that response rate did not differ significantly between groups (RR=1.29, 95%CI (0.94, 1.76), p=0.11).
- 4 studies reported that ultrasound-guided injections resulted in thinner plantar fascial thickness than palpation-guided injections (MD= -0.12, 95%CI (-0.22, -0.01), p=0.03).
- 3 studies reported that ultrasound-guided injections resulted in less hypoechogenicity than palpation-guided injections (RR=0.30, 95%CI (0.12, 0.77), p=0.01).
- 2 studies reported heel pad thickness did not differ significantly between groups (MD=0.62, 95%CI (-1.84, 3.09), p=0.62), meaning no atrophy occurred.
最も覚えておくべきことは？
Patients who received ultrasound-guided corticosteroid injections had a higher tenderness threshold, thinner plantar fascial thickness, and a lower incidence of hypoechogenicity compared to palpation-guided corticosteroid injections. Pain, heel tenderness index, response rate, and heel pad thickness were similar between groups.
それが私の患者ケアにどのように影響するか？
Based on the presented evidence, an ultrasound-guided injection of corticosteroid appears to be more effective than palpation-guided injections for plantar fasciitis. Additional well designed, high-quality, randomized control trials with larger sample sizes are needed to confirm these results.
