Abstract :
Introduction: Injection of local anaesthetic with steroid to block the suprascapular nerve (SSN) is a common method for pain management of patients with chronic shoulder pain. Ultrasound guided pulsed radiofrequency (PRF) ablation is a new modality, with comparatively lesser adverse effects. Aims and Objectives: To compare the effectiveness of ultrasound guided PRF ablation versus injection of local anaesthetic with steroid to block the SSN for pain management of patients with chronic shoulder pain. Materials and Methods: Forty patients diagnosed with chronic shoulder pain were randomly allocated to receive either PRF of SSN or blockade of the nerve with methylprednisolone 40 mg and 0.25% bupivacaine. Numeric rating score (NRS), Shoulder pain and disability index (SPADI) and passive range of motion (PROM) were evaluated at 2,4,8 and 12 weeks and Effective pain relief (EPR? 50% reduction in NRS) recorded at 12 weeks. Results: No significant difference in NRS was present between both the groups at 12 weeks. NRS decreased significantly from baseline values (p-value =0.00) at various time intervals in both groups. 11 (55%) patients reported EPR at 3 months in the PRF group and 13 (65%) in the BS group (p=0.12). A statistically significant (p Less than 0.001) improvement in SPADI score and PROM in both groups at various time intervals was also achieved. No intergroup difference in NRS (p=0.23), SPADI (p=0.44) and PROM (p>0.05). Conclusion: Ultrasound-guided PRF of SSN provided a similar decrease in pain, improvement in SPADI score and PROM up to 12 weeks when compared with block with bupivacaine-steroid.
