Ultrasound-Guided Interphalangeal Injection (US-IPI) of Mucoid Cysts As a Non-Surgical Option: Technical Notes and Clinical Efficacy
Anesthesia Research(2024)
摘要
Digital mucous cysts (DMCs) are common soft tissue tumors affecting interphalangeal joints. Various treatment options exist, with surgical excision being the standard. Ultrasound-guided cortisone (CC) injection into the distal interphalangeal (DIP) joint has been proposed as a therapeutic alternative. This study aims to assess the technical success and clinical efficacy of US-IPI in terms of swelling resolution and pain control. Fifty-two patients with DMCs underwent CCs DIP joint ultrasound-guided infiltration. Eighty-three percent of patients exhibited a positive response to US-IPI, with a significant reduction in NRS pain scores (p < 0.01). Persistent pain in 17% of patients was effectively managed with marked improvement after a secondary infiltration. Joint swelling was reduced in 68% of patients within 1 month, with complete resolution by 3 to 6 months. No recurrence was reported at the 6-month follow-up. Pain assessment using the Numeric Rating Scale and joint swelling evaluation were conducted at follow-ups of 2 weeks, 1, 3, and 6 months. Statistical analysis was performed to compare pre- and post-procedure NRS pain scores. Here, we show that US-IPI of DMCs is an effective therapeutic option that provides immediate pain relief and long-term aesthetic improvement, resulting in an alternative option to surgical excision.
