RESUMO

BACKGROUND: Malnutrition is a known risk factor for complications and adverse outcomes after elective total joint arthroplasty (TJA), but little is known about the burden this risk factor places on the healthcare system. The purpose of this study was to evaluate the 90-day impact of malnutrition on medical and surgical complications and understand the increase in global reimbursements associated with TJA in malnourished patients. METHODS: We queried a combined private-payer and Medicare database from 2007 to 2016 for TJA using International Classification of Diseases, 9th revision and Current Procedural Terminology codes. Patients with serum albumin level of <3.5 g/dL were gender, age, and mean Elixhauser Comorbidity Index matched against a cohort with a normal serum albumin level. Odds ratios and confidence intervals were calculated for complications at 90 days postoperatively. Mean index and 90-day global reimbursements were calculated for the two matched groups and compared using P-values. RESULTS: 3053 protein malnourished patients receiving TJA were identified, and 12,202 matched protein nourished patients receiving TJA served as controls. At 90 days, the malnourished groups had increased risk for failure of multiple organ systems, periprosthetic joint infection, and reoperation. The mean 90-day increase in reimbursement was $3875 associated with performing a TJA on a protein malnourished patient (P < .001). CONCLUSION: This study demonstrates an association between malnourished patients and postoperative complications as well as significantly increased reimbursements. Understanding the reimbursement increases at 90 days for TJA in protein malnourished patients is important in the era of bundled payments.

RESUMO

Objectives: Recent studies have established the usage of virtual reality (VR) to help alleviate acute and chronic pain. VR technology can be cost prohibitive and cheaper alternatives are desired. In this study, a Google Cardboard headset ($15) combined with a smartphone was used as a low-cost VR device to assess efficacy in altering the perception of pain. Materials and Methods: The cold pressor test, a minimal-risk method, was used to simulate pain. Participants immersed their hands into ice water, with and without VR, in a crossover manner, and their pain perception data were recorded. Results: Forty-eight healthy volunteer participants completed the study between 2017 and 2018. Participants were randomized to right hand control, left control, right experimental, and left experimental groups, respectively, before the crossover. Data collected included pain threshold (time at which participants first reported pain), pain tolerance (time at which participants removed their hand), and pain intensity (highest reported pain level on a [1-10] scale). Approximately two-thirds of participants had improvements in pain threshold and pain tolerance with a mean improvement of +13.0 seconds (P = 0.0045) for pain threshold and +29.8 seconds (P = 0.0003) for pain tolerance. Pain intensity had a reduction of 0.43 points (P = 0.0371). Conclusion: Our results demonstrate that inexpensive VR devices, such as the Google Cardboard headset used in this study, may be a safe, portable, and cost-effective way to alter the perception and improve tolerance of pain.

RESUMO

Ninety-six wrists (56 right and 40 left) in 96 patients (36 males and 60 females, mean age 38, range 15-77 years) underwent repair of ulnotriquetral ligament split tears between 2007 and 2016. Mayo wrist scores, visual analogue scale pain scores, and objective measures including grip strength and range of motion were obtained. Patients were assessed after a mean follow-up of 21 months (range 6-112 months). Ulnotriquetral split tear repair resulted in substantial improvements in pain and function. The mean Mayo wrist score improved from 57 preoperatively to 81 postoperatively, with 84% of patients achieving a good or excellent outcome. Pain scores decreased from 5.8 to 1.2. Grip improved from 25 kg to 29 kg. There was no significant change in range of motion of the wrist. Complications were noted in eight patients, with three experiencing continued pain, four with dysaesthesia of the dorsal sensory ulnar nerve, and one superficial infection. Arthroscopic ulnotriquetral split tear repair significantly reduced pain and improved Mayo wrist scores. Level of evidence: IV.

RESUMO

OBJECTIVE: To determine whether operating on "major" vertebral fractures leads to premature abortion of surgery and/or other acute cardiopulmonary complications. DESIGN: Retrospective review. CLINICAL SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS AND INTERVENTION: We retrospectively queried our institutional Trauma Rregistry for all cases presenting with concomitant rib fractures and surgically managed vertebral fractures. MAIN OUTCOME MEASUREMENTS: The main outcomes included the surgical outcome (aborted vs. successfully performed), total and Intensive Care Unit length of stay (LOS), adverse discharge, mortality, and functional outcomes. RESULTS: We found 57 cases with concomitant segmental rib fractures and surgically managed vertebral fractures. Seven patients (12%) received a rib fixation, of which 1 received before vertebral fixation and 6 after. Importantly, 4 vertebral fixation cases (7.02%) had to be aborted intraoperatively because of the inability to tolerate prone positioning for surgery. For case-control analysis, we performed propensity score matching to obtain matched controls, that is, cases of vertebral fixation but no rib fractures. On matched case-control analysis, patients with concomitant segmental rib fractures and vertebral fractures were found to have higher Intensive Care Unit LOS [median = 3 days (Inter-Quartile Range = 0-9) versus. 8.4 days, P = 0.003], whereas total LOS, frequency of complete, incomplete or functional spinal cord injury, discharge to rehab, and discharge to nursing home were found to be similar between the 2 groups. CONCLUSION: Our findings demonstrate that segmental rib fractures with concomitant vertebral fractures undergoing surgical treatment represent a subset of patients that may be at increased risk of intraoperative cardio-pulmonary complications and rib fixation before prone spine surgery for cases in which the neurological status is stable is reasonable. LEVEL OF EVIDENCE: Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.
