An unusual complication of quadriparesis after trigger point injection: a case report.

Quadriparesis after intramuscular trigger point injections for myofascial pain syndrome has been rarely reported in the literature. A 37-year-old male patient presented with myofascial pain syndrome and was given trigger point injections in trapezius muscles under ultrasound guidance. The patient noticed weakness in all the 4 limbs at approximately 12 hours after the procedure, which gradually progressed to functional quadriplegia at the time of presentation to the emergency department.

Comparison of Continuous Femoral Nerve Block versus Local Infiltration Analgesia as a Postoperative Analgesia in Unilateral Total Knee Arthroplasty.

Introduction: Local infiltration of knee joint in arthroplasty, provide postoperative analgesia and preserves motor power of quadriceps, which helps in early mobilisation, as compared to femoral nerve block which paralyses vastus medialis.

Aim: To compare the quality of postoperative analgesia provided by femoral nerve block and local infiltration in unilateral Total Knee Arthroplasty (TKA).

Materials And Methods: A prospective study was conducted on 60 patients (25-65 years) of ASA I and II, which were randomly(using random number table) divided into two groups - Group 1-femoral nerve block (FNB) and Group 2-Local Infiltration Analgesia (LIA).
