Lumbopelvic dissociation is an extremely rare injury to the junction of the lumbar spine and sacrum seen in high-energy trauma, for which the operative treatment has not been established, especially in the setting of hardware infection. In this case report, we describe the case of a 37-year-old male who presented to the spine surgery team after undergoing six surgeries, all following a traumatic car accident ten years prior.The patient initially presented with symptomatic lumbar hyperlordosis that had progressively limited his ability to perform activities of daily living. He suffered from paraplegia and a sensory deficit at the T8 level and below but still maintained control over his bowel and bladder. The surgical team performed two operations: one to improve his quality of life by correcting the degree of lordosis he was suffering from due to a 76-degree sacral slope and the second to perform re-instrumentation after the patient suffered a traumatic injury three weeks after the initial operation that occurred after assisting with his own wheelchair transfers.His prior surgeries include operations for deformity correction as well as irrigation and debridement secondary to hardware infection and subsequent removal. He reported that following the hardware removal he had significant pain and was no longer able to easily sit and play with his child or reach countertops while in his wheelchair, severely impacting his quality of life.The surgical team performed two operations on this patient: the first to correct the lordotic deformity utilizing a four-rod construct, and a second performed three weeks later to perform re-instrumentation utilizing a five-rod construct and hematoma evacuation following hardware failure secondary to high biomechanical strain from performing his own wheelchair transfers.
Introduction: Total knee arthroplasty (TKA) is now being performed in the outpatient setting, and often the postoperative pain is managed with opioid analgesics. Non-opioid pain management modalities are in crucial demand, and we propose a surgical technique that can potentially result in less pain and the decrease in the use of opioid analgesia following TKA. The purpose of this study was to investigate the safety and efficacy of a novel peripheral nerve block (PNB) that includes a single injection and catheter placement for a continuous regional nerve block in total knee arthroplasty. Methods: Fifty-six patients underwent TKA by a single surgeon utilizing the novel method. Patient-reported outcomes were entered into an outcomes database and compared to an aggregate of over 3,500 comparative TKA patients. A visual analog scale (VAS) evaluated perioperative pain. Patient perioperative opioid usage, expectations of pain control, the incidence of common side effects, and the average hospital length of stay (LOS) were collected. Results: Compared to the aggregate of patients in the database, the patients who received the novel surgeon-placed adductor canal block (ACB) and catheter placement reported findings that suggest this technique can possibly lead to a decrease in the severity of pain in addition to a reduction in side effects and the need for opioid analgesia. LOS for these patients was short, and patient satisfaction scores were excellent for the surgeon performing this technique. Conclusions: Using the placement technique described, surgeons can reproducibly perform a single injection of PNB and place an indwelling catheter in the adductor canal through direct visualization of the muscles that make up the borders of the adductor canal. This technique offers potential advantages over pain management modalities that can be elucidated in further studies. The power of this study is limited due to these findings having not been analyzed for statistical significance.
