Abstract | BACKGROUND: HYPOTHESIS: We hypothesized that the US-guided CI is superior to blind CI in symptom improvement and development of skin hypopigmentation or atrophy. PATIENTS AND METHODS: Forty-four patients (48 wrists) with dQD received ultrasonography-guided CI (24 wrists/22 patients, group A) or blind CI (24 wrists/22 patients, group B) between December 2016 and February 2018. The visual analogue scale for pain and the Patient-rated Wrist Evaluation (PRWE) were used for evaluation. Skin hypopigmentation or atrophy was evaluated using the modified Vancouver scar scale (mVSS) RESULTS: At 4 weeks post-injection, pain and PRWE scores improved for 22 wrists in group A and 21 wrists in group B. At 3 months post-injection, 10.0% (2/20) and 26.3% (5/19) of wrists in group A and B, respectively, had symptom recurrence after initial improvement. Improvement and aggravation rates were not significantly different between the groups. The incidence of skin hypopigmentation or atrophy was 69.6% (16/23 wrists) and 70.0% (14/20 wrists) in group A, and 59.1% (13/22 wrists) and 78.9% (15/19 wrists) in group B at 4 weeks and 3 months post-injection, respectively. The mean mVSS scores at the injection site in group A and B were 2.0 (0-4.0) and 1.8 (0-5.0) at 4 weeks post-injection and 2.4 (0-7.0) and 2.9 (0-6.0) at 3 months post-injection, respectively. The incidence and severity of skin hypopigmentation or atrophy were not significantly different between the groups at both time points. DISCUSSION:
Pain and clinical outcomes significantly improved after CI in dQD. Pain, clinical outcomes, and the incidence and severity of skin hypopigmentation or atrophy were not significantly different between ultrasonography-guided and blind CI. LEVEL OF EVIDENCE: I, Therapeutic.
