Patient preferences for physical therapy programs after a lower extremity fracture: a discrete choice experiment.

OBJECTIVE: To quantify patients' preferences for physical therapy programmes after a lower extremity fracture and determine patient factors associated with preference variation. DESIGN: Discrete choice experiment. SETTING: Level I trauma centre. PARTICIPANTS: One hundred fifty-one adult (≥18 years old) patients with lower extremity fractures treated operatively. INTERVENTION: Patients were given hypothetical scenarios and asked to select their preferred therapy course when comparing cost, mobility, long-term pain, session duration, and treatment setting. MAIN OUTCOME MEASURES: A multinomial logit model was used to determine the relative importance and willingness to pay for each attribute. RESULTS: Mobility was of greatest relative importance (45%, 95% CI: 40% to 49%), more than cost (23%, 95% CI: 19% to 27%), long-term pain (19%, 95% CI: 16% to 23%), therapy session duration (12%, 95% CI: 9% to 5%) or setting (1%, 95% CI: 0.2% to 2%). Patients were willing to pay US$142 more per session to return to their preinjury mobility level (95% CI: US$103 to US$182). Willingness to pay for improved mobility was higher for women, patients aged 70 years and older, those with bachelor's degrees or higher and those living in less-deprived areas. Patients were willing to pay US$72 (95% CI: US$50 to US$93) more per session to reduce pain from severe to mild. Patients were indifferent between formal and independent home therapy (willingness to pay: -US$12, 95% CI: -US$33 to US$9). CONCLUSIONS: Patients with lower extremity fractures highly value recovering mobility and are willing to pay more for postoperative physical therapy programmes that facilitate returning to their pre-injury mobility level. These patient preferences might be useful when prescribing and designing new techniques for postoperative therapy.

The Use of Vancomycin Powder in Tibial Plateau Fractures at Lower Risk of Infection.

OBJECTIVE: To determine the effectiveness of vancomycin powder in preventing infection after plate and screw fixation of tibial plateau fractures considered at low risk of infection. DESIGN: Retrospective cohort study. SETTING: Single, Level I trauma center. PATIENTS/PARTICIPANTS: This study included 459 patients with tibial plateau fractures (OTA/AO 41-B/C) who underwent open reduction and internal fixation from 2006 to 2018 and were considered at low risk of infection based on not meeting the "high risk" definition of the VANCO trial. INTERVENTION: Vancomycin powder administration on wound closure at the time of definitive fixation. MAIN OUTCOME MEASUREMENTS: Deep surgical site infection with at least 1 gram-positive bacteria culture. RESULTS: Vancomycin powder administration was associated with reduction in gram-positive infection from 4% to 0% (odds ratio, 0.12; 95% confidence interval, 0.04-0.32; P < 0.01). No significant effect was reported in gram-negative only infections, which were observed in 0.3% in the control group, compared with 0.9% in the intervention group (odds ratio, 2.71; 95% confidence interval, 0.11-69; P = 0.54). Methicillin-resistant Staphylococcus aureus was the most common organism isolated in the control group, growing in 9 of 18 infections (50%). CONCLUSIONS: Among patients with low-risk tibial plateau fractures, vancomycin powder at the time of definitive fixation showed a reduction in the incidence of gram-positive deep surgical site infection. The observed relative effect was relatively larger than that observed in a previous randomized trial on high-risk fractures. These data might support broadening the indication for use of vancomycin powder to include tibial plateau fractures at low risk of infection. LEVEL OF EVIDENCE: Therapeutic Level III.

Outcomes of Tibiotalocalcaneal Hindfoot Fusion Nails Used for Acute Lower Extremity Trauma in a High-Risk Patient Population.

OBJECTIVE: To determine the outcomes of high-risk patients treated with tibiotalocalcaneal hindfoot fusion nails. DESIGN: Retrospective case series. SETTING: Level I trauma center. PATIENTS/PARTICIPANTS: Between January 2007 and December 2016, 50 patients with significant medical comorbidities treated with a tibiotalocalcaneal hindfoot fusion nail in the setting of acute distal tibia and ankle trauma considered to be limb-threatening. INTERVENTION: Tibiotalocalcaneal hindfoot fusion nail. MAIN OUTCOME MEASUREMENTS: Two-year cumulative incidence of unplanned reoperation and estimated survival with limb salvage at 2 years. RESULTS: Of the 50 patients, 20 (38%) had an unplanned reoperation (mean: 2.5 reoperations), including 19 for implant removal, 11 for irrigation and debridement and/or placement of an antibiotic delivery device, and 4 for revision fusion. Three patients required amputation and 3 patients died within 2 years of injury, resulting in an estimated survival with limb salvage at 2 years of 79% (95% confidence interval: 67%-91%). After accounting for the competing risk of death and incomplete follow-up, the 2-year cumulative incidence of unplanned reoperation was 64% (95% confidence interval: 62%-67%). CONCLUSIONS: Patients in this series experienced a high rate of return to the operating room but a relatively low rate of amputation. Because patients were indicated for this course of treatment on the basis of comorbidities felt to put them at high risk of loss of limb with traditional treatment, acute hindfoot fusion nailing might represent a viable option in select high-risk patients and injuries. Clinicians should be aware that complications are still common. LEVEL OF EVIDENCE: Therapeutic Level IV. See Instructions for Authors for a complete description of levels of evidence.

Does iliosacral screw removal reduce postoperative pain in unstable pelvic fracture patients? A matched prospective cohort study.

BACKGROUND: To compare pain and function in patients with unstable posterior pelvic fractures stabilized with posterior fixation who undergo iliosacral screw removal versus those who retain their iliosacral screws. METHODS: A prospective observational cohort study identified 59 patients who reported pain at least 4 months after iliosacral screw fixation of an unstable posterior pelvic ring fracture from 2015-2019. The primary intervention was iliosacral screw removal versus a matched iliosacral screw retention control group. Patient-reported pain was measured with the 10-point Brief Pain Inventory, and patient-reported function was measured with the Majeed Pelvic Outcome Score. Both measured within 6 months of the intervention. RESULTS: Before iliosacral screw removal, the mean pain was 4.7 (SD, 3.0) compared with 4.7 (SD, 3.0) in the matched control group. Following iliosacral screw removal, the average pain in the screw removal group was 3.7 (SD, 2.7) and 3.3 (SD, 2.5) in the matched control group. We found no evidence that iliosacral screw removal reduced pain in this population (mean difference, 0.2 points; 95% CI, -1.0 to 1.5; p = 0.71). In addition, the improvement in function after iliosacral screw removal was not statistically indistinguishable from zero (mean difference, 3.1 points; 95% CI, -4.6 to 10.9; p = 0.42). CONCLUSIONS: The results suggest that iliosacral screw removal offers no significant pelvic pain or function benefit when compared with a matched control group. Surgeons should consider these data when managing patients with pelvic pain who are candidates for iliosacral screw removal.

Pattern Recognition of the Multiple Sclerosis Syndrome.

During recent decades, the autoimmune disease neuromyelitis optica spectrum disorder (NMOSD), once broadly classified under the umbrella of multiple sclerosis (MS), has been extended to include autoimmune inflammatory conditions of the central nervous system (CNS), which are now diagnosable with serum serological tests. These antibody-mediated inflammatory diseases of the CNS share a clinical presentation to MS. A number of practical learning points emerge in this review, which is geared toward the pattern recognition of optic neuritis, transverse myelitis, brainstem/cerebellar and hemispheric tumefactive demyelinating lesion (TDL)-associated MS, aquaporin-4-antibody and myelin oligodendrocyte glycoprotein (MOG)-antibody NMOSD, overlap syndrome, and some yet-to-be-defined/classified demyelinating disease, all unspecifically labeled under MSsyndrome. The goal of this review is to increase clinicians' awareness of the clinical nuances of the autoimmune conditions for MS and NMSOD, and to highlight highly suggestive patterns of clinical, paraclinical or imaging presentations in order to improve differentiation. With overlay in clinical manifestations between MS and NMOSD, magnetic resonance imaging (MRI) of the brain, orbits and spinal cord, serology, and most importantly, high index of suspicion based on pattern recognition, will help lead to the final diagnosis.

Discordant functional and inflammatory parameters in multiple sclerosis patients after autologous haematopoietic stem cell transplantation.

This article describes outcomes in four patients with advanced multiple sclerosis up to two years after autologous haematopoietic stem cell transplantation using a total-body irradiation-based preparative regimen. MRI and CSF analyses demonstrated clear suppression of the inflammatory processes. The results demonstrate however, a dissociation of inflammation parameters and functional disability findings raising questions about optimal future stem cell transplantation strategies for this disease.
