Complications After Continuous Posterior Lumbar Plexus Blockade for Total Hip Arthroplasty: A Retrospective Cohort Study.
While benefits of regional anesthesia in total hip arthroplasty (THA) are well documented, data describing the incidence of complications related to the use of posterior lumbar plexus blockade for THA remain limited. Our primary aim was to evaluate the incidence of infectious, bleeding, and neurological complications related specifically to the use of continuous posterior lumbar plexus block for elective THA. ⋯ In our large, single-center cohort study, we report no catheter-related infections, whereas catheter-related hemorrhagic and neurological complications also appear to be rare.

Case ReportsDiskitis, Osteomyelitis, Spinal Epidural Abscess, Meningitis, and Endocarditis Following Sacroiliac Joint Injection for the Treatment of Low-Back Pain in a Patient on Therapy for Hepatitis C Virus.
Sacroiliac joint injections are frequently performed procedures in the management of acute and chronic low-back pain, including patients with various immunocompromised states. Infectious complications following these procedures along with other spinal injections are rarely reported, but the true incidence is unknown. The purpose of this report is to highlight the devastating neurologic sequela that can occur, and to discuss potential future management strategies. ⋯ Immunocompromised patients should be identified prior to treatment, and the small possibility of devastating complications should be thoughtfully weighed against the potential benefit of the procedure. Conservative management should be maximized initially, and if a procedure is done, strict asepsis must be maintained. Prophylaxis for S. aureus should be considered for immunocompromised patients undergoing interventional spine procedures.

Sensory Distribution of the Lateral Cutaneous Nerve of Forearm After Ultrasound-Guided Block: Potential Implications for Thumb-Base Surgery.
Surgery of the wrist and hand commonly involves regional anesthesia of the median nerve and superficial radial nerve within the forearm. In this sonographic study, the contribution of the lateral cutaneous nerve of forearm (LCNF) to thumb cutaneous sensation was studied. Patients scheduled for thumb suspension arthroplasty (n = 35) were examined by ultrasound, with LCNF, median nerve, and superficial radial nerve identified. ⋯ Bifurcation occurred further distally, 18 (2.6) mm from the interepicondylar line. In 14 of 15 cases, LCNF sensory distribution extended to the thumb base, 8.3 (7.8) mm distal to the radiocarpal joint. This study has demonstrated the LCNF to innervate the thumb base, indicating neural blockade of this nerve may be required for surgery of the basal thumb joint.
