RESUMO
BACKGROUND: SOT recipients are commonly prescribed immunosuppressive therapies which may predispose patients to higher infection and complication rates following total shoulder arthroplasty. This article aims to analyze the effects SOT and subsequent immunosuppressive regimens have on the functional and patient reported outcomes of total shoulder arthroplasties. METHODS: A single institution, multi-surgeon retrospective case-control study investigating the functional and patient reported outcomes of shoulder arthroplasty after SOT was conducted between the years of 2010-2020. To be included in the study, patients must have undergone SOT prior to primary total shoulder arthroplasty. A 4:1 match-paired control group lacking SOT prior to arthroplasty was then constructed. Thirty-four SOT patients (18 males and 16 females) and 136 control patients (77 male and 59 female) were included in the study. Patients were analyzed who underwent SOT prior to shoulder arthroplasty, with outcomes compared to controls who only underwent arthroplasty. The primary outcomes include range of motion (ROM) and strength in forward elevation, external rotation, and internal rotation, and patient reported outcomes. RESULTS: There was no significant difference in improvement for range of motion and strength between the two cohorts, but within each cohort, improvement was statistically significant. In the SOT patients, forward elevation improved by 56o ± 52o, external rotation increased 13o ± 20o, and internal rotation increased by two vertebral levels. In the non-SOT patients, forward elevation improved 45o ± 51o, external rotation increased 16o ± 25o, and internal rotation increased by three vertebral levels. SOT patients had equivocal VAS pain and Simple Shoulder Test scores but lower ASES (59 ± 13 vs 79 ± 2; p=0.002) and SANE (61 ± 30 vs 84 ± 17; p<.001) scores than non-SOT patients. Complication rates were significantly higher in the SOT group (15% vs 6%; p=0.05), but incidence of surgical revisions was not significantly different (SOT = 3%; non-SOT = 5%; p=0.59). CONCLUSION: Shoulder arthroplasty is a safe, effective surgical intervention for improving shoulder function in patients with a history of SOT. Despite being on chronic immunosuppressive regimens, our solid organ transplants had comparable clinical outcomes and revision rates, but higher complication rates.
RESUMO
INTRODUCTION: Lactic acid is well studied in the trauma population and is frequently used as a laboratory indicator that correlates with resuscitation status and has thus been associated with patient outcomes. There is limited literature that assesses the association of initial lactic acid with post-operative morbidity and hospitalization costs in the orthopedic literature. The purpose of this study was to assess the association of lactic acid levels and alcohol levels post-operative morbidity, length of stay and admission costs in a cohort of operative lower extremity long bone fractures, and to compare these effects in the ballistic and blunt trauma sub-population. METHODS: Patients presenting as trauma activations who underwent tibial and/or femoral fixation at a single institution from May 2018 to August 2020 were divided based on initial lactate level into normal, (< 2.5) intermediate (2.5-4.0), and high (> 4.0). Mechanism of trauma (blunt vs. ballistic) was also stratified for analysis. Data on other injuries, surgical timing, level of care, direct hospitalization costs, length of stay, and discharge disposition were collected from the electronic medical record. The primary outcome assessed was post-operative morbidity defined as in-hospital mortality or unanticipated escalation of care. Secondary outcomes included hospital costs, lengths of stay, and discharge disposition. Data were analyzed using ANOVA and multivariate regression. RESULTS: A total of 401 patients met inclusions criteria. Average age was 34.1 ± 13.0 years old, with patients remaining hospitalized for 8.8 ± 9.5 days, and 35.2% requiring ICU care during their hospitalization. Patients in the ballistic cohort were younger, had fewer other injuries and had higher lactate levels (4.0 ± 2.4) than in the blunt trauma cohort (3.4 ± 1.9) (p = 0.004). On multivariate regression, higher lactate was associated with post-operative morbidity (p = 0.015), as was age (p < 0.001) and BMI (p = 0.033). ISS, ballistic versus blunt injury mechanism, and other included laboratory markers were not. Lactate was also associated with longer lengths of stay, and higher associated direct hospitalization cost (p < 0.001) and lower rates of home disposition (p = 0.008). CONCLUSION: High initial lactate levels are independently associated with post-operative morbidity as well as higher direct hospitalization costs and longer lengths of stay in orthopedic trauma patients who underwent fixation for fractures of the lower extremity long bones. Ballistic trauma patients had significantly higher lactate levels compared to the blunt cohort, and lactate was not independently associated with increased rates of post-operative morbidity in the ballistic cohort alone. LEVEL OF EVIDENCE: III.

OBJECTIVE: To analyze the visual outcomes and sequelae of endonasal intervention for orbital infections. INTRODUCTION: Orbital infections pose a serious threat to vision in the pediatric population and can result in complications such as blindness, diplopia, intracranial involvement, and death. [1] Orbital decompression by endonasal intervention is a common treatment to address a variety of orbital infections including orbital cellulitis, orbital abscesses, and subperiosteal abscesses. [2] The outcomes of visual sequelae such as loss or limitation of visual acuity, extraocular movements, and increased intraocular pressure following orbital decompression via endonasal intervention have not been sufficiently investigated in the current literature. METHODS: This retrospective cohort study was performed at our tertiary care pediatric hospital using data from 69 patients aged 0-18 years who were admitted between 2008 and 2018. Data was extracted from the electronic medical record system. RESULTS: Following endoscopic sinus surgery, symptoms of orbital infection improved throughout the cohort. Improvement in visual acuity is demonstrated by a statistically significant decrease in the average logMAR value in both the right and left eye (P = 0.002 and P = 0.028 respectively). There was also a significant improvement to normal values postoperatively for patients who initially presented with abnormal tonometry, extraocular movement, and the appearance of eyelids and eyelashes. CONCLUSION: There is no decline or loss of vision with otolaryngology surgical intervention for orbital cellulitis in our cohort. This retrospective chart review demonstrates the efficacy of surgical intervention on overall visual outcomes following endonasal intervention for orbital infections such as orbital cellulitis, orbital abscesses, and subperiosteal abscesses.
