Risk Factor Analysis for Fat Infiltration in the Lumbar Paraspinal Muscles in Patients With Lumbar Degenerative Diseases

Introduction This study aimed to investigate factors related to fat infiltration in patients with lumbar degenerative diseases (lumbar disc herniation and/or spinal stenosis), examining a wide range of potential risk variables. Materials and methods We studied consecutive adult patients who underwent posterior lumbar spinal surgery for degenerative diseases at our hospital between July 2013 and June 2017. Preoperative magnetic resonance imaging was used to evaluate the presence or absence of fat infiltration at the level of the L4-5 lumbar paraspinal muscles using Kjaer’s evaluation method. Patients without fat infiltration (0%–10%) were rated as grade 0, grade 1 for moderate fat infiltration (10%–50%), and grade 2 for severe fat infiltration (>50%). Patients were then divided into two groups: Group A (without fat infiltration, grade 0) and Group B (with fat infiltration, grade 1 or 2). Detailed patient clinical data were collected and analyzed. Results A total of 205 consecutive patients were enrolled; 54 (26.3%) patients were assigned to Group A and 151 (73.7%) to Group B. Logistic regression analysis revealed two independent risk factors for fat infiltration of the lumbar paraspinal muscles: female sex and older age (P < .001). Discussion Fat infiltration of the lumbar paraspinal muscles is reported to be associated with the development of pain and dysfunction of the lumbar region and postoperative complications of spinal instrumented fusion surgery. To the best of our knowledge, no previous studies have identified female sex and older age as independent risk factors for fat infiltration in the lumbar paraspinal muscles using multivariate analysis. Conclusions Female sex and older age were independent risk factors for fat infiltration in the lumbar paraspinal muscles. The results of the current study may provide useful information for the study of preventive measures for fat infiltration.

Association of Acute Perioperative Myocardial Injury With All-Cause Mortality Within 90 Days After Hip Fracture Repair in the Elderly: A Prospective Study

Introduction It remains unclear whether acute perioperative myocardial injury (APMI) increases mortality in the elderly. This study aimed to investigate APMI’s association with mortality within 90 days after hip fracture repair in elderly patients. Materials and Methods This prospective study enrolled elderly patients admitted to the department of Traumatology and Orthopaedics in XXX Hospital, who underwent surgery in 2018–2019 with a 90-day follow-up. According to survival status within 90 days, survival and death groups were constituted. Clinical, demographic, and laboratory indicators and 90-day mortality post-surgery were recorded. APMI’s association with 90-day mortality post-surgery was analyzed by logistic regression. Results Totally 248 participants were enrolled, including 224 and 24 in the survival and death groups, respectively, for a mortality rate of 9.7%. Compared with surviving individuals, the death group was older [81 (75–86) vs 87 (82–89) years], and had higher incidence rates of APMI (24.6% vs 58.3%), intertrochanteric fractures (41.1% vs 62.5%), preoperative atrial fibrillation (8.9% vs 29.2%), and dementia (73.7% vs 95.8%) (all P<.05). They also showed higher pre-injury frail scale scores [1 (0–2) vs 3 (1–4)] and Nottingham hip fracture scores (NHFSs) [4 (4–5) vs 6.5 (5–7)], lower Glomerular filtration [62 (46.1–78.6) vs 44.37 (35–61.92) ml/min], and reduced odds of glomerular filtration rate <60 mL/min (75.0% vs 46.9%) (all P < .05). APMI (OR = 3.294, 95% CI: 1.217–8.913) and NHFS (OR = 2.089, 95% CI: 1.353–3.225) independently predicted 90-day mortality post-surgery (all P<.05). Conclusions APMI is associated with increased mortality risk within 90 days after hip fracture repair in elderly patients.

The Effect of Femoral Nerve Block and Adductor Canal Block Methods on Patient Satisfaction in Unilateral Knee Arthroplasty: Randomized Non-Inferiority Trial

Introduction: Femoral Nerve Block (FNB) and Adductor Canal Block (ACB) methods, which are regional analgesic techniques, are successfully used in postoperative pain control after total knee arthroplasty. This study aimed to compare adductor canal block method that was preoperatively used and femoral nerve block method in total knee arthroplasty (TKA) patients who underwent spinal anesthesia in terms of factors effecting patient satisfaction and determine whether these methods were equally effective or not. Methods: A total of 80 patients between the ages of 60 and 75 who were in the American Society of Anesthesia (ASA) physical status of I-III were prospectively included in this randomized study. Patients (n = 40) who received FNB were called Group FNB and patients (n = 40) who received Adductor Canal Block were called Group ACB. Results: Although mean postoperative VAS values were lower in FNB group only in the first hour (p = 0.02) there was no significant difference between the groups in the third, fifth, seventh, ninth, 12th and 24th hours (p≥0.05). Although Bromage scores were lower in FNB group in the first, second, third, fourth and fifth hours there was no statistically significant difference between the groups (p≥0.05). When mobilization time, patient satisfaction level, time of first analgesia, intraoperative sedation need, and recovery time of sensorial block were compared no statistically significant difference was found (p≥0.05). Discussion: When ACB and FNB that are used for postoperative analgesia in patients who undergo total knee arthroplasty are compared in terms of factors affecting patient satisfaction it is observed that they result in the same level (non-inferiority) of patient satisfaction. Conclusion: We recommend the routine use of ACB method with FNB in total knee arthroplasty. More studies focusing especially on measuring patient satisfaction are needed.

Prior Admissions as a Risk Factor for Readmission in Patients Surgically Treated for Femur Fractures: Implications for a Potential Hip Fracture Bundle

Introduction: Hip fractures are a significant economic burden to our healthcare system. As there have been efforts made to create an alternative payment model for hip fracture care, it will be imperative to risk-stratify reimbursement for these medically comorbid patients. We hypothesized that patients readmitted to the hospital within 90 days would be more likely to have a recent previous hospital admission, prior to their injury. Patients with a recent prior admission could therefore be considered higher risk for readmission and increased cost. Methods: A retrospective chart review identified 598 patients who underwent surgical fixation of a hip or femur fracture. Data on readmissions within 90 days of surgical procedure and previous admissions in the year prior to injury resulting in surgical procedure were collected. Logistic regression analysis was used to determine if recent prior admission had increased risk of 90-day readmission. A subgroup analysis of geriatric hip fractures and of readmitted patients were also performed. Results: Having a prior admission within one year was significantly associated (p < 0.0001) for 90-day readmission. Specifically, logistic regression analysis revealed that a prior admission was significantly associated with 90-day readmission with an odds ratio of 7.2 (95% CI: 4.8-10.9). Discussion: This patient population has a high rate of prior hospital admissions, and these prior admissions were predictive of 90-day readmission. Alternative payment models that include penalties for readmissions or fail to apply robust risk stratification may unjustly penalize hospital systems which care for more medically complex patients. Conclusions: Hip fracture patients with a recent prior admission to the hospital are at an increased risk for 90-day readmission. This information should be considered as alternative payment models are developed for hip fracture care.

The Surgical Outcomes of Unstable Ankle Fractures in Patients Aged >65 Years

Aim: To evaluate the surgical outcomes and complications of patients over 65 years of age, with unstable ankle fractures. Material and Method: The study included 111 patients (73F/38 M) operated on between January 2015 and February 2019 and followed up for a mean of 21.2 months (range, 6-62 months).Demographic characteristics, comorbidities, fracture type, and mechanisms of injury were evaluated. Relationships between postoperative complications and comorbidities were examined. In the postoperative functional evaluations, the AOFAS score was used and pre and postoperative mobilization (eg, use of assistive devices) was assessed. Results: The mean age of the patients was 70.5 ± 6.1 years (range, 65-90 years). The mechanism of trauma was low-energy trauma in 90.1% of the fractures and high-energy trauma in 9.9%. The fractures were formed with a SER injury (supination external rotation) in 83.7% of cases and bimalleolar fractures were seen most frequently (85/111, 76%).Complications developed in 16 (14.4%) patients and a second operation was performed in 11 (9.9%) patients with complications. Plate was removed and debridement was performed in 5 of 6 patients due to wound problems. Nonunion was developed in the medial malleolus in 4 patients. Revision surgery was performed because of implant irritation in 2 patients and early fixation loss in the medial malleolus fracture in one patient. Calcaneotibial arthrodesis was performed in 3 patients because of implant failure and ankle luxation associated with non-union. A correlation was determined between ASA score and DM and complications, but not with osteoporosis. The mean follow-up AOFAS score was 86.7 ± 12.5 (range, 36-100).A total of 94 (84.7%) patients could walk without assistance postoperatively and 92 (82.9%) were able to regain the preoperative level of mobilization. Conclusion: Although surgery can be considered an appropriate treatment option for ankle fractures in patients aged >65 years, care must be taken to prevent potential complications and the necessary precautions must be taken against correctable comorbidities.

Characteristics and Outcomes of Hip Fracture Patients Hospitalized in an Orthogeriatric Unit Versus an Orthopedic Department: A Retrospective Cohort Study

Introduction: Hip fractures are a significant health risk in older adults and a major cause of morbidity, functional decline and mortality. Our aim was to compare clinical outcomes of older patients hospitalized in an ortho-geriatric (OG) unit to those hospitalized in an orthopedic department (OD) for surgical treatment of a hip fracture. Methods: A retrospective cohort study of hip fractured patients hospitalized between 2015-2016 in a single tertiary university-affiliated medical center. Included were patients aged 65 and older who had undergone hip fracture surgery and were admitted to either a geriatric or orthopedic ward. Results: 441 patients met the inclusion criteria (195 in the OG unit, 246 in the OD); 257 were transferred to an affiliated geriatric center hospital (107 from the OG unit and 127 from the OD) for rehabilitation. Patients in the OG unit were older, more cognitively and functionally impaired and with more comorbidities. The 1-year mortality rate was significantly lower in the OD group (OR 0.32, CI 95% 0.19-0.53, p < 0.001), however, after propensity matching, the 30-day and 1 year mortality rates were similar in both groups. No difference was found in the rehabilitation length of stay between the groups. The functional independence measure improvement was similar in both groups, with a non-significant trend toward better functional improvement among OG unit patients. Conclusions: Despite the higher complexity of patients, worse baseline functional capacity in the OG unit, improvement after rehabilitation was similar in both groups. These results demonstrate the advantages of the OG unit in treating and stabilizing frail older adults, thus maximizing their chances for a successful recovery after hip fractures. Level of Evidence: Level IV

Low-Energy Pelvic Ring Fractures: A Care Conundrum

Introduction: A need exists for improved care pathways for patients experiencing low-energy pelvic ring fractures. A review of the current literature was performed to understand the typical patient care and post-acute rehabilitation pathway within the US healthcare system. We also sought to summarize reported clinical outcomes worldwide. Significance: Low-energy pelvic ring fracture patients usually do not qualify for inpatient admission, yet they often require post-acute rehabilitative care. The Center for Medicare and Medicaid Services’ (CMS) 3-day rule is a barrier to obtaining financial coverage of this rehabilitative care. Results: Direct admission of some patients to post-acute care facilities has shown promise with decreased cost, improved patient outcomes, and increased patient satisfaction. Secondary fracture prevention programs may also improve outcomes for this patient population. Conclusions: Post-acute care innovation and secondary fracture prevention should be prioritized in the low-energy pelvic fragility fracture patient population. To demonstrate the effect and feasibility of these improved care pathways, further studies are necessary.

The Correlation Between Timing of Surgery and the Need for RBC Transfusions in the Geriatric Intertrochanteric Fracture Population

Objective: To identify whether the timing of surgery affects red blood cell (RBC) transfusion requirements in the elderly with intertrochanteric fractures. Methods: We retrospectively studied all patients undergoing surgical fixation of their intertrochanteric fractures in our hospital between January 2009 and December 2018 and analyzed the relationship between the timing of surgery and RBC transfusion. Results: A total of 679 patients were included in this study. The need for RBC transfusion was lower in the patients who underwent surgery within 12 h after admission (timing of surgery <12 h, <12 h group) than those who underwent surgery over 12 h after admission (timing of surgery >12 h, >12 h group) (P = 0.046); lower in the the patients who underwent surgery within 24 h after admission (timing of surgery <24 h, <24 h group) than in those who underwent surgery over 24 h after admission (timing of surgery >24 h, >24 h group) (P = 0.008), and lower in the <24 h group compared to the patients who underwent surgery within 48 h after admission (timing of surgery <48 h, <48 h group) (P = 0.035). Moreover, the need for RBC transfusion was lower in the <24 h group (in the first 24 h from admission to surgery) than in the 24-48 h group (in the second 24 h from admission to surgery) (P = 0.016), and also lower in the <24 h group compared to the 48-72 h group (in the third 24 h from admission to surgery) (P = 0.047). However, there were no differences between the <12 h group and 12-24 h group, between the <12 h group and <24 h group, and between the 12-24 h group and <24 h group, respectively. Conclusion: Timing of surgery within 24 h contributes to the reduction of RBC transfusion in the elderly with intertrochanteric fractures.

Sagittal Deformity Correction in a Patient Suffering From Diffuse Idiopathic Skeletal Hyperostosis Who Previously Underwent a Total Hip and Bilateral Knee Replacement

Introduction: Physiological aging frequently leads to degenerative changes and spinal deformity. In patients with hypolordotic fusions or ankylosing illnesses such as diffuse idiopathic skeletal hyperostosis or ankylosing spondylitis, compensation mechanisms can be altered causing severe pain and disability. In addition, if a total hip replacement and/or knee replacement is performed, both pelvic and lower limbs compensation mechanisms could be damaged and prosthetic dislocation or impingement syndrome could be present. Pedicle subtraction osteotomy has proven to be the optimal correction technique for spinal deformation in patients suffering from a rigid spine. Case Presentation: A 70-year-old male patient with diffuse idiopathic skeletal hyperostosis criteria and a rigid lumbar kyphosis, who previously underwent a total hip and knee replacement, had severe disability. We then performed corrective surgery by doing a pedicle subtraction osteotomy. The procedure and outcomes are presented here. Conclusion: In symptomatic patients with sagittal imbalance and a rigid spine, pedicle subtraction osteotomy can indeed correct spinal deformity and re-establish sagittal balance.

Toe Clearance Rehabilitative Slippers for Older Adults With Fall Risk: A Randomized Controlled Trial

Introduction: To evaluate fall-prevention rehabilitative slippers for use by self-caring, independent older adults. Materials and Methods: This assessor-blinded, randomized, and controlled 1-year study included 59 self-caring, independent participants (49 women) who attended day services. The mean age of participants was 84.0 ± 5.3 years. Participants were randomly selected from 8 nursing homes. We tested slippers top-weighted with a lead bead (200, 300, or 400 g). Intervention group participants walked while wearing the slippers for 10-20 min, 1-3 days/week at the day service center. Fall risk was measured using the Berg Balance Scale and the Tinetti Performance-Oriented Mobility Assessment (POMA) before and at 3-month intervals after the intervention/control phase. Results: After 12 months, the intervention group demonstrated significant improvement. Berg Balance and POMA compared to the control group ( p < .05 p < .01, respectively). Mobility scores improved significantly for both measurements in the intervention group before and after ( p < .01), but the control group had significantly lower scores. Discussion: Overall, falls decreased in the intervention group from 10 to 7, and control group falls increased from 9 to 16 ( p = .02). No adverse events related to the intervention were reported. Conclusions: Rehabilitation training slippers may reduce falls in older adults.
