ABSTRACT

Introduction: While there is anecdotal evidence that the coronavirus disease 2019 (COVID-19) pandemic altered perioperative decision-making in patients requiring posterior cervical fusion (PCF), a national-level analysis to examine the significance of this hypothesis has not yet been conducted. This study aimed to determine the potential differences in perioperative variables and surgical outcomes of PCF performed before vs. during the COVID-19 pandemic. Methods: Adults who underwent PCF were identified in the 2019 (prepandemic) and 2020 (intrapandemic) NSQIP datasets. Differences in 30-day readmission, reoperation, and morbidity were evaluated using multivariate logistic regression. On the other hand, differences in operative time and relative value units (RVUs) were estimated using quantile regression. Furthermore, the odds ratios (OR) for length of stay (LOS) were estimated using negative binomial regression. Secondary outcomes included rates of nonhome discharge and outpatient surgery. Results: A total of 3,444 patients were included in this study (50.7% from 2020). Readmission, reoperation, morbidity, operative time, and RVUs per minute were similar between cohorts (p>0.05). The LOS (OR 1.086, p<0.001) and RVUs-per-case (coefficient +0.360, p=0.037) were significantly greater in 2020 compared to 2019. Operation year 2020 was also associated with lower rates of nonhome discharge (22.3% vs. 25.8%, p=0.017) and higher rates of outpatient surgery (4.8% vs. 3.0%, p=0.006). Conclusions: During the COVID-19 pandemic, a 28% decreased odds of nonhome discharge following PCF and a 72% increased odds of PCF being performed in an outpatient setting were observed. The readmission, reoperation, and morbidity rates remained unchanged during this period. This is notable given that patients in the 2020 group were more frail. This suggests that patients were shifted to outpatient centers possibly to make up for potentially reduced case volume, highlighting the potential to evaluate rehabilitation-discharge criteria. Further research should evaluate these findings in more detail and on a regional basis.

ABSTRACT

Introduction: Ankle fractures in geriatric patients can be devastating injuries, as they limit an individual's mobility, autonomy, and quality of life. This study examines the functional outcomes and complications related to hindfoot nails (HFN) in geriatric patients who have suffered an ankle malleolar or distal tibia fracture. Materials and Methods: This is a single-surgeon case-series of patients who underwent HFN for acute fixation or delayed reconstruction after an ankle or distal tibia fracture. Demographic information, comorbidities, baseline functional status, AO/OTA classification, surgical indications, need for external fixation, total operative time, length of stay (LOS), ambulation at discharge, and discharge disposition were recorded. Primary outcomes included 30-day complications, ambulation at follow-up, and time to fracture union and fusion. Results: There were 22 patients, with average age 80.8 years. Mean LOS was 7.0 days, and 68.2% were discharged to subacute rehabilitation. Within 30 days, 1 patient developed a deep vein thrombosis and bilateral pulmonary emboli, and 2 experienced wound dehiscence requiring antibiotics. At 6-weeks, 1 patient sustained a fall with periprosthetic fracture requiring HFN revision, and another developed cellulitis necessitating hardware removal. Fracture healing was seen in 72.7% at 19.4 weeks, while radiographic fusion occurred in 18.2% at 43.0 weeks. 72.7% were ambulating with an assistive device at discharge, and 100.0% at 12-weeks post-operatively or last follow-up. Upon final examination, all patients were ambulating without pain. Discussion: HFNs provide a reliable alternative to traditional open reduction internal fixation and have the ability to improve quality of life for geriatric patients through a faster return to weight-bearing. Additionally, radiographic fusion rates show that patients have favorable functional outcomes even without formal arthrodesis. Conclusion: HFN is beneficial for elderly patients with low functional demand and complex medical comorbidities, as it allows for early mobility after sustaining an ankle or distal tibia fracture.

ABSTRACT

BACKGROUND: Patient-reported outcome measures (PROMs) are often lower following conversion total hip arthroplasty (cTHA) compared to matched primary total hip arthroplasty (THA) controls. However, the minimal clinically important differences (MCIDs) for any PROMs are yet to be analyzed for cTHA. This study aimed to (1) determine if patients undergoing cTHA achieve primary THA-specific 1-year PROM MCIDs at comparable rates to matched controls undergoing primary THA and (2) establish 1-year MCID values for specific PROMs following cTHA. METHODS: A retrospective case-control study was conducted using 148 cases of cTHA which were matched 1:2 to 296 primary THA patients. Previously defined anchor values for 2 PROM measures in primary THA were used to compare cTHA to primary THA, while novel cTHA-specific MCID values for 2 PROMs were calculated through a distribution method. Predictors of achieving the MCID of PROMs were analyzed through multivariate logistic regressions. RESULTS: Conversion THA was associated with decreased odds of achieving the primary THA-specific 1-year Hip dysfunction and Osteoarthritis Outcome Score for Joint Replacement PROM (Odds Ratio: 0.319, 95% Confidence Interval: 0.182-0.560, P < .001) and Patient Reported Outcomes Measurement Information System Physical Function Short-Form-10a PROM (Odds Ratio: 0.531, 95% Confidence Interval: 0.313-0.900, P = .019) MCIDs in reference to matched primary THA patients. Less than 60% of cTHA patients achieved an MCID. The 1-year MCID of the Hip dysfunction and Osteoarthritis Outcome Score for Joint Replacement and Patient Reported Outcomes Measurement Information System Physical Function Short-Form-10a specific to cTHA were +10.71 and +4.68, respectively. CONCLUSION: While cTHA is within the same diagnosis-related group as primary THA, patients undergoing cTHA have decreased odds of achieving 1-year MCIDs of primary THA-specific PROMs. LEVEL OF EVIDENCE: Level III, retrospective comparative study.

ABSTRACT

STUDY DESIGN: This is a multicenter, prospective cohort study. OBJECTIVE: This study tests the hypothesis that the elimination of lower limb compensation in patients with adult spinal deformity (ASD) will significantly increase the magnitude of sagittal malalignment. SUMMARY OF BACKGROUND DATA: ASD affects a significant proportion of the elderly population, impairing functional sagittal alignment and inhibiting the overall quality of life. To counteract these effects, patients with ASD use their spine, pelvis, and lower limbs to create a compensatory posture that allows for standing and mobility. However, the degree to which each of the hips, knees, and ankles contributes to these compensatory mechanisms has yet to be determined. METHODS: Patients undergoing corrective surgery for ASD were included if they met at least one of the following criteria: complex surgical procedure, geriatric deformity surgery, or severe radiographic deformity. Preoperative full-body x-rays were evaluated, and age and pelvic incidence -adjusted normative values were used to model spine alignment based upon three positions: compensated (all lower extremity compensatory mechanisms maintained), partially compensated (removal of ankle dorsiflexion and knee flexion, with maintained hip extension), and uncompensated (ankle, knee, and hip compensation set to the age and pelvic incidence norms). RESULTS: A total of 288 patients were included (mean age 60 yr, 70.5% females). As the model transitioned from the compensated to uncompensated position, the initial posterior translation of the pelvis decreased significantly to an anterior translation versus the ankle (P.Shift: 30 to -7.6 mm). This was associated with a decrease in pelvic retroversion (pelvic tilt: 24.1-16.1), hip extension (SFA: 203-200), knee flexion (knee angle: 5.5-0.4), and ankle dorsiflexion (ankle angle: 5.3-3.7). As a result, the anterior malalignment of the trunk significantly increased: sagittal vertical axis (65-120 mm) and G-SVA (C7-ankle from 36 to 127 mm). CONCLUSIONS: Removal of lower limbs compensation revealed an unsustainable truncal malalignment with two-fold greater SVA.

ABSTRACT

STUDY DESIGN: Retrospective review of prospective database. OBJECTIVES: Vertebral pelvic angles (VPAs) account for complexity in spine shape by assessing the relative position of each vertebra with regard to the pelvis. This study uses VPAs to investigate the shape of the fused spine after T10-pelvis fusion, in patients with adult spinal deformity (ASD), and then explores its association with proximal junctional kyphosis (PJK). METHODS: Included patients had radiographic evidence of ASD and underwent T10-pelvis realignment. VPAs were used to construct a virtual shape of the post-operative spine. VPA-predicted and actual shapes were then compared between patients with and without PJK. Logistic regression was used to identify components of the VPA-based model that were independent predictors of PJK occurrence and post-operative shape. RESULTS: 287 patients were included. VPA-predicted shape was representative of the true post-operative contour, with a mean point-to-point error of 1.6-2.9% of the T10-S1 spine length. At 6-weeks follow-up, 102 patients (35.5%) developed PJK. Comparison of the true post-operative shapes demonstrated that PJK patients had more posteriorly translated vertebrae from L3 to T7 (P < .001). Logistic regression demonstrated that L3PA (P = .047) and T11PA (P < .001) were the best independent predictors of PJK and were, in conjunction with pelvic incidence, sufficient to reproduce the actual spinal contour (error <3%). CONCLUSIONS: VPAs are reliable in reproducing the true, post-operative spine shape in patients undergoing T10-pelvis fusion for ASD. Because VPAs are independent of patient position, L3PA, T11PA, and PI measurements can be used for both pre- and intra-operative planning to ensure optimal alignment.

ABSTRACT

BACKGROUND: The purpose of this study was to detail perioperative ophthalmologic evaluations to characterize functional ocular outcomes after facial bipartition surgery. METHODS: Patients with hypertelorbitism who underwent facial bipartition surgery were studied specifically for eye motility disorders by separating patients into rare craniofacial clefts (midline and paramedian) (n = 34) and craniofacial dysostosis (Apert, Crouzon, and Pfeiffer) (n = 74). Preoperative and postoperative (12 months) ophthalmologic examinations (with depth perception tests), computed tomography scans, and magnetic resonance imaging scans were analyzed. RESULTS: Among craniofacial cleft patients, mean interdacryon distance was reduced from 39 ± 4 mm to 17 ± 2 mm, with strabismus improved from 88 percent (exotropia 82 percent) preoperatively to only 29 percent postoperatively. Depth perception improved to a lesser degree, with abnormal tests at a rate of 79 percent preoperatively to 56 percent postoperatively. Wider hypertelorbitism had a higher degree of strabismus. Among craniofacial dysostotic patients, mean interdacryon distance was reduced from 37 ± 3 mm to 17 ± 2 mm, and strabismus improved from 55 percent to only 14 percent. Depth perception improved to a lesser degree, with 68 percent abnormal tests preoperatively and 46 percent postoperatively. Apert patients had more V-pattern strabismus and exotropia (79 percent) than did other craniofacial dysostosis patients (42 percent). CONCLUSIONS: The authors' data indicate that facial bipartition for hypertelorbitism-known to improve periorbital aesthetics-also improves eye motility disturbances. Thus, vision problems related to exotropia should be considered a functional indication for facial bipartition surgery in patients with hypertelorbitism. CLINICAL QUESTION/LEVEL OF EVIDENCE: Therapeutic, IV.

ABSTRACT

BACKGROUND: Plastic surgery education consists of technical skills, surgical decision-making, and the knowledge necessary to provide safe patient care. Competency in these modalities is ensured by requiring case minimums and oral and written examinations. However, there is a paucity of information detailing what teaching modalities residency programs use outside of the operating room. METHODS: A 16-question survey was sent to all integrated and independent program directors. Information regarding nonsurgical resident education was collected and analyzed. RESULTS: There were 44 responses (46 percent). Most programs had six to 10 faculty (43 percent), and a majority (85 percent) required faculty to participate in resident education outside of the operating room. Residents most commonly had 3 to 4 hours (43 percent) of protected educational time 1 day per week (53 percent). Nonsurgical education consisted of weekly lectures by attending physicians (44 percent) and residents (54 percent), in addition to weekly CoreQuest (48 percent), teaching rounds (38 percent), and Plastic Surgery Education Network lectures (55 percent). Monthly activities included morbidity and mortality conference (81 percent) and journal club (86 percent). Indications conference was either monthly (41 percent) or weekly (39 percent). Cadaver laboratories, visiting professors, board preparation, in-service review, and meetings with the program director occurred yearly or several times per year. Forty-nine percent of programs sponsor one educational course per resident. In addition, most programs (65 percent) do not receive outside funding for education. CONCLUSIONS: These findings improve understanding of the current state of nonsurgical resident education in plastic surgery. They illustrate that residents participate in a diverse number of nonsurgical educational activities without any significant standardization.
