Introduction: To quantify the incidence of and identify predictors for unplanned first-week return visits (1wRV) to the emergency department (ED) after circumferential casting (CC) application for pediatric forearm fractures. Materials and Methods: Retrospective, single-center study of patients aged 0 to 18 years with radius and/or ulna fractures. The primary outcome was unplanned ED revisit within 7 days (1wRV). Analyses included demographic variables, and fracture type, location, reduction versus casting in situ, and cast length. Multivariable logistic regression was used to identify predictors of 1wRV. Results: A total of 4661 cases were reviewed, with detailed analysis of 551 patients treated with CC in 2022. Among these, 67 (12.2%) experienced a 1wRV, most commonly due to pain (92.5%), with 95.5% requiring cast modification. Revisit rates varied by fracture location: distal radius and ulna (23.8%), midshaft radius and ulna (15.7%), distal radius (8.5%), and other fractures (5.5%; P =0.007), and were higher following reduction versus in-situ casting (16.1% vs. 4.3%; P <0.001; OR 3.265), peaking at 27.1% for reduced distal radius and ulna fractures. No compartment syndrome occurred, and 98.4% of patients completed nonoperative treatment successfully. Conclusions: Rates of 1wRV ranged from 0 to 27.1%, depending on fracture pattern and the need for reduction, and constituted the most common adverse event associated with CC. These granular findings underscore the need for a more individualized approach to immobilization and may inform the development of tailored, evidence-based nonoperative protocols for pediatric forearm fractures.

Background: Osteochondritis dissecans (OCD) healing can be unpredictably slow, incomplete, or absent after surgical treatment. This frustrates patients, families, and the medical team. We aimed to develop an algorithm to predict the speed of OCD radiographic ossification based on patient demographic, physical, surgical, and imaging data. Methods: We studied a prospective cohort of patients with knee OCD lesions in a multicenter database. We included patients who were diagnosed with knee OCD lesions of the lateral or medial femoral condyle and were treated operatively at a single center. We collected patient information from medical records and imaging studies. Radiographic healing was defined on the basis of the percentage of the original OCD lesion that had a normal bone density (ossification) compared with the surrounding condyle, rated on a continuous scale from 0 to 100. An OCD lesion that achieved ≥90% of the normal surrounding bone density at 6 months following surgery was defined as fast healing. Follow-up was conducted with radiographs only. Multivariable logistic regression and receiver operating characteristic (ROC) curve analyses were performed. Results: This study included 79 OCD lesions in 72 individuals. The mean patient age was 13.79 ± 2.71 years (range, 8.56 to 22.98 years), and 45 (62.5%) of the 72 patients were male. A total of 56 patients (77.8%) were White, and 69 patients (95.8%) were of non-Hispanic ethnicity. In all, 23 lesions (29.1%) fit the of fast healing. A multivariable regression analysis revealed that high preoperative bone density within the OCD lesion (p < 0.001) was the only feature that had an association with fast healing. A preoperative lesion density rating of ≥70% predicted fast ossification with a sensitivity of 87% and a specificity of 66.1%. Conclusions: A preoperative OCD density rating that was ≥70% of that of the normal surrounding bone was found to be the only independent predictor of fast ossification following surgery.

Background/Objectives: Efficient allocation of hospital resources is crucial in managing lower extremity trauma. Selected patients with stable injuries may not require inpatient hospitalization while awaiting surgical fixation. This study describes the feasibility and safety of a structured Home-based Preoperative Management (HPM) pathway for such patients. Methods: We conducted a retrospective, single-center observational study of 187 adult patients with isolated lower extremity fractures managed with HPM between 2019 and 2022. All patients were discharged home from the Emergency Department with standardized instructions, immobilization, anticoagulation, and planned follow-up. No comparator group was included. Results: Of 187 patients (mean age 49.7 y), 23 patients (12.3%) returned to the Emergency Department during the preoperative waiting period. The mean time from Emergency Department presentation to surgery was 8.5 days. Overall, 164 patients (87.7%) completed the preoperative waiting period at home without requiring an additional Emergency Department visit. Within one year after surgery, 51 patients (27.3%) presented to the Emergency Department; 29 of these visits (56.9%) were considered surgery-related. Patients who returned to the Emergency Department before surgery had a higher likelihood of postoperative Emergency Department visits within one year compared with those who did not (69.6% versus 21.3%, p < 0.001). Time to surgery was not associated with postoperative Emergency Department visits (p = 0.763). Conclusions: In this retrospective cohort, Home-Based Preoperative Management was feasible and appeared safe for carefully selected patients with lower extremity trauma. Most patients were able to await surgery at home without unplanned Emergency Department visits. Given the absence of a comparator group, no conclusions regarding comparative effectiveness or superiority over inpatient management can be drawn.

Background/Objectives: Osteoporotic fractures, particularly subcapital hip fractures (SCF), pose a significant healthcare and economic burden. The routine pathological examination of resected femoral heads in such cases is common practice, aimed at identifying malignancies that may have contributed to bone fragility. This study evaluated the cost-effectiveness and clinical utility of routine femoral head pathology in patients undergoing surgical treatment for SCF. Methods: A retrospective cohort study was conducted at a university-affiliated, tertiary care hospital. Patients undergoing surgical treatment for SCF between 2015 and 2018, with available femoral head pathology reports, were included. Data on demographics, prior or active malignancies, surgical procedures, and pathology results were analyzed. Results: The study included 230 patients with a mean age of 82.4 ± 14.1 years, of whom 57% were female. A total of 72 (31%) patients had a history of malignancy at the time of surgery. Pathological examination identified malignancies in eight patients (3.4%), all of whom had active malignancies at the time of admission. The most common malignancies detected were breast cancer and multiple myeloma (three cases each). None of the findings led to changes in patient management. Conclusions: The routine pathological examination of femoral heads following SCF provided a limited diagnostic yield and did not alter clinical management in this cohort. These findings suggest that routine pathology may not be cost-effective and support the adoption of selective screening approaches based on clinical risk factors such as a history of malignancy or atypical fracture presentations.

Background and Objectives: The aim of this study was to test whether there is a necessity for routine postoperative laboratory testing in patients undergoing primary elective unilateral total knee arthroplasty (TKA), with the administration of Tranexamic Acid (TXA) and without the use of tourniquet. Materials and Methods: This observational, retrospective cohort study was conducted at Meir Medical Center. The data were collected in 2018–2022. Patients were collected in a consecutive manner. There were no exclusion criteria for this study. The inclusion criteria were individuals who underwent elective TKA due to end-stage osteoarthritis (OA). We conducted a multivariable logistic regression analysis to determine the factors associated with postoperative hemoglobin (PoOHb) < 9 g/dL and the optimal cutoff to detect those patients postoperatively. Results: A total of 271 patients were included. The mean preoperative hemoglobin (PrOHb) was 13.02 ± 1.42 g/dL, and the mean PoOHb was 11.5 ± 1.34 g/dL. The mean decrease in Hbg levels following surgery was 1.52 ± 0.91 g/dL. In all, 271 patients had a PoOHb level ≥ 9 g/dL or above. A total of 16 patients received packed red blood cells following surgery. Patients with PoOHb < 9 g/dL had a significantly lower PrOHbg. In the current study, all 11 patients who had PoOHb < 9, 10 (90.9%) had PrOHb ≤ 1011.95 55 g/dL, compared to 25 (49.6%) of the 260 patients who had PoOHb ≥ 9. The odds ratio for having PrOHb ≤ 10.9511.55 g/dL if PoOHb < 9 g/dL was 206.6710.4 (95% CI 24.427.164 to 1749.01415.97). A cut-off of 11.2510.25 would have offered a sensitivity of 99% (specificity 93.5%). Conclusions: In conclusion, this study supports using selective post-TKR Hgb monitoring rather than adhering to routine practice. An association between postoperative anemia and the need for blood transfusion was found only when the preoperative baseline hemoglobin threshold was less than 10.95 g/dL.

Background: Vertebral compression fractures (VCFs) are the most prevalent type of osteoporotic fractures, often causing significant pain, morbidity, and mortality. Vertebral augmentation procedures like balloon kyphoplasty (BK) are effective in treating VCFs. These procedures are typically performed using a single fluoroscopy machine (SF) for anteroposterior (AP) and lateral views. We have implemented a dual-fluoroscopy (DF) technique to reduce procedure time and radiation exposure. The goal of this study was to determine whether dual-fluoroscopy could optimize surgical efficiency without compromising safety, offering a more effective alternative to traditional single-fluoroscopy methods. Methods: This retrospective study included 126 patients who underwent BK with either SF (n = 74, 58.7%) or DF (n = 52, 41.3%) between 2020 and 2024. We collected data on procedure duration per pedicle (PDPP), radiation exposure (reference air kerma and dose-area product [DAP]), and radiation duration. A sub-analysis of post-learning phase cases was performed. Results: A learning curve was identified for the first 24 cases and 15 cases using the SF technique and DF technique, respectively, which was followed by a stabilization in procedure duration per pedicle (Levene’s statistic = 10.623, p = 0.002 for SD difference, p < 0.001 for mean PDPP difference). After the completion of the learning phase for both techniques, the DF group demonstrated a significantly shorter PDPP (11.83 ± 4.3 vs. 14.03 ± 5.57 min, p = 0.049). No significant differences were found in radiation exposure, including radiation duration (p = 0.577), reference air kerma, or DAP. Conclusions: Dual-fluoroscopy significantly reduces procedure time after the learning curve is overcome, improving efficiency without increasing radiation exposure. This technique holds promise for optimizing kyphoplasty workflow and safety, supporting broader clinical adoption.

Background: The most published surgical technique for fixating Type 4 (Salter–Harris II) tibial tubercle avulsion fractures is uni-cortical in nature, and stability is suboptimal. This study presents a technique modification that is consistent with AO principles, by which the screws are aimed distally to purchase the posterior cortex of the distal fragment. This technique is defined as a “Distal Cortical Fixation”. This modification has not been studied to date and harbors potential advantages. We aimed to assess the safety and efficacy of surgical fixation techniques for the above-mentioned fractures and to describe the new modification. Methods: A retrospective review was conducted at a level 1 children’s hospital for surgically treated Salter–Harris II tibial tubercle fractures. Inclusion criteria were patients who sustained Salter–Harris II tibial tubercle avulsion fractures and were documented to reach one of two radiographic endpoints: union (regardless of alignment) or non-union that necessitated additional interventions. Medical records and radiographic studies were analyzed for fracture union and alignment. A comparative analysis was conducted to evaluate outcomes based on different fixation techniques that included Distal Cortical Fixation, a Proximal Screw Technique, and a crossed or multiple screws/pins construct. Results: A total of 37 patients were included with a mean age of 14.8 ± 1.2 years, with 34/37 (91.9%) being male. The most common procedure was a 1 to 3 screw fixation with a Distal Cortical Fixation (n = 21 (56.75%)), followed by a Proximal Screw Technique (n = 8, 21.62%), and a crossed or multiple screws/pins construct (n = 8, 21.62%). There was no difference between the groups in medical history and demographic features. The mean follow-up duration was 35.17 ± 36.79 weeks. There were no non-unions, and only a minimal change in the sagittal and coronal alignment (0.4 ± 1.94 (p = 0.872) and 0.53 ± 3.51 (p = 0.296) degrees, respectively) was noted and was not associated with the surgical technique. Conclusions: The surgical treatment of Salter–Harris II tibial tubercle avulsion fractures, including Distal Cortical Fixation, was presented and was found to provide satisfactory union rates on a short term follow up.

Background: Total hip arthroplasty (THA) is a standard treatment for a displaced femoral neck fracture in the elderly. In contemporary healthcare, there is a global shift towards fast-track treatment modalities, prioritizing early hospital discharge for patients. Consequently, routine postoperative blood tests may become redundant, offering significant time and cost savings. We aim to evaluate postoperative hemoglobin levels in trauma-related THA cases and identify patient profiles for whom these tests hold significance. Methods: A retrospective review of 176 THA procedures performed between 2018 and 2022, focusing on individuals undergoing THA for displaced femoral neck fractures. Multivariable logistic regression analysis was employed to identify factors associated with postoperative hemoglobin levels below 8.5 g/dL. Results: Of the 176 patients included, 109 (61.9%) were women and the mean age was 69.09 ± 8.13 (range 27 to 90) years. The majority of the patients underwent surgery within 48 hours of admission. The mean preoperative hemoglobin (Hb) level was 13.1 ± 1.4 g/dL, while the mean postoperative Hb level was 10.5 ± 1.2 g/dL. Only six patients (3.41%) exhibited postoperative Hb levels of ≤8.5 g/dL. No significant associations were found between postoperative Hb levels ≤ 8.5 and any demographic, surgical, or medical characteristics. Conclusions: Our findings suggest that routine postoperative blood count testing may not be necessary for most patients undergoing THA for displaced femoral neck fractures, particularly those without complications or significant comorbidities.

Background: This study compared outcomes of the direct anterior approach (DAA) and direct lateral approach (DLA) for treating displaced femoral neck fractures in active elderly patients. Methods: This retrospective study included active elderly patients who sustained a displaced femoral neck fracture and underwent a cementless total hip arthroplasty either with a supine DAA or a decubitus DLA. Patients were assessed using the Harris hip score at discharge and at a 6-week follow-up. Results: A total of 41 women and 18 men were included in the study. Of those, 22 underwent DLA and 37 received DAA, all performed by the same team. In both groups, 69% were women, mean age was 70 years, and mean BMI was 25.2. Mean hemoglobin loss was 2.3 g/dl between admission and the first post-operative day in both groups. Similar numbers in each cohort were discharged home rather than to a rehabilitation center. The patients who underwent the DAA experienced a 2-day reduction in their hospital stay compared to the DLA group (4.2 ± 1.9 vs. 6.8 ± 3.7, respectively; p < 0.001). The Harris hip score in the DAA group was significantly higher at the 6-week follow-up than in the DLA group (87.23 ± 7.75 vs. 81.23 ± 7.67, respectively; p < 0.031). Conclusions: The patients who underwent THA with the DAA demonstrated better short term outcomes compared to the alternative approach for displaced femoral neck fractures in active elderly patients. DAA helped patients regain independence faster and might decrease hospitalization and rehabilitation costs. Based on these results, we recommend using the DAA for active elderly patients with a displaced femoral neck fracture.
