Abstract
Carpal tunnel syndrome is the most common upper limb neuropathy with increasing incidence especially among females. It has a high economic and social impact on patients.
CTS can be treated either with conservative measures or surgically. Local corticosteroid injection is used in conservative treatment where its anti-inflammatory therapeutic effect is helpful in relieving the inflammatory process occurring in carpal tunnel syndrome. Steroid injection could be carried out using anatomical landmarks, or using ultrasonographic guidance.
The aim of our study is to compare the clinical outcomes between the ultrasound guided injection Vs palpation guided injection for carpal tunnel syndrome patients.
This study was carried in radiology department, Suez canal university hospitals where 76 eligible patients with different degrees of carpal tunnel syndrome were referred from rheumatology department in Suez canal university hospitals, 38 patients were injected using palpation guided technique using Philips Ultrasound Device. Model HD 11, probe L12-3, as well as 38 patients were injected using palpation guided technique, as well as another 38 patients were injected under ultrasonographic guidance using cocktail 0.5 ml of plain lidocaine 1% & 0.5ml of 40mg triamcinolone is injected using a 3 ml 24 gauge 1.5 inch needle.
Baseline pain, pain at outcome (2 weeks and 12 weeks) were determined using visual analogue scale, patient satisfaction, complications, difficulty of procedure and duration of procedure were determined.
There was significant improvement of clinical outcomes between the 2 groups where patients injected under ultrasound guidance shows better outcomes.
