This study evaluated the spread of a local anesthetic, using MRI and sensory blockade, after an intertransverse process block (ITPB) at the medial aspect of the retro-superior costotransverse ligament (retro-SCTL) space - the medial retro-SCTL space block. ⋯ A single-injection medial retro-SCTL space block, at the T4-T5 level with 10.5 ml of local anesthetic, consistently spreads to the ipsilateral intercostal and paravertebral spaces, sympathetic chain, costotransverse space, neural foramina and epidural space, but produces ipsilateral sensory blockade that is variable and wider over the posterior than anterior hemithorax.

Auricular hematoma is a condition commonly seen in the emergency department among patients presenting with trauma to the ear. It may result in several complications such as perichondritis and cauliflower ear if not managed appropriately. ⋯ Emergency clinicians must be knowledgeable regarding the evaluation and management of auricular hematoma, including the various drainage techniques.

Total knee arthroplasty is a life-changing surgical procedure that is associated with a high incidence of severe postoperative pain. Key to enhancing recovery after surgery is effective analgesia and early mobilisation. Innovations in motor-sparing regional anaesthesia techniques that have improved recovery include targeted surgical local infiltration analgesia, adductor canal blockade, genicular nerve blocks, and the infiltration between the popliteal artery and posterior capsule of the knee (iPACK) block. This narrative review discusses the current available motor-sparing regional anaesthetic techniques and assesses the evidence supporting each.

In this study, the spread of methylene blue was compared between an ultrasound-guided Pericapsular Nerve Group (PENG) block and a double injection technique, where the approach towards the inferomedial acetabulum was added to the latter. ⋯ Our study demonstrates adequate staining of the iliac bone with comparable distal and medial spread in both techniques, indicating that the PENG block with a single injection is adequate in blocking the hip capsule with 10 mL local anesthetics. Staining of the femoral nerve occurred in 2/6 specimens after the PENG block, and staining of the obturator nerve in 1 specimen in each group.

Coccygodynia results from traumatic, nontraumatic, or idiopathic causes. Chronic cases resistant to conservative treatments may necessitate surgery. ⋯ S-MPB was chosen for its simplicity, efficacy, and safety, providing postoperative analgesia without complications. This approach suggests that S-MPB is a promising addition to the pain management arsenal for coccygectomy, warranting further investigation to optimize its application and outcomes.
