Background: The present study analyzes the effects of preoperative serum albumin, hematocrit, and creatinine on postoperative outcomes in patients undergoing carpal tunnel decompression surgery. Methods: The American College of Surgeons National Quality Improvement Program (NSQIP) database was queried from 2011 to 2020. Albumin, hematocrit, and creatinine were collected for each patient, alongside covariates. Outcomes included 30-day medical complications, 30-day wound complications, return to the operating room, nonhome discharge, and extended postoperative length of stay. Bivariate t-tests and multivariate logistic regressions were conducted. For any outcome-laboratory value pairs with significance on regression, area under the receiver operating characteristic curves (AUC) were constructed. Results: A total of 1440 patients with albumin, 3138 patients with hematocrit, and 3159 patients with creatinine levels were identified. Increased serum albumin was associated with lower odds of medical complications (aOR: 0.479, p=0.035). An overall cohort cutoff of ≤ 3.5 g/dL (AUC: 0.79, p < 0.001) was predictive of medical complications. On multivariate logistic regression, increased hematocrit reduced the odds of medical complications (aOR: 0.889, p < 0.001). Predictive hematocrit cutoffs of ≤ 39.7% (AUC: 0.77, p < 0.001) and ≤ 36.6% (AUC: 0.74, p < 0.001) were identified for medical complications amongst male and female patients, respectively. Similarly, increased serum creatinine was associated with greater odds of medical complications (aOR: 1.684, p=0.006). Creatinine cutoffs of ≥ 1.2 mg/dL (AUC: 0.58, p=0.033) and ≥ 1.0 mg/dL (AUC: 0.59, p=0.039) were identified for medical complications amongst male and female patients, respectively. Conclusions: Multiple preoperative serum values were predictive of postoperative medical complications, and laboratory value thresholds were identified in this carpal tunnel decompression cohort to aid in risk stratification.

Background: Orthopedic trauma is a significant component of emergency department workloads worldwide. The relationship between weather conditions and injury rates is controversial in modern literature. Even less has been written to investigate bank holidays' influence on contusions, dislocations, fractures, and even polytrauma. Our study aimed to assess whether meteorological factors and national holidays could vary the workloads in the orthopedic ER of a European third-level trauma center. Materials and Methods: Our study consisted of a review of all the patients who underwent orthopedic evaluations in our institution's orthopedic emergency room between 2019 and 2023. Days were divided depending on weather (cloudy or sunny vs. rainy or stormy), day type (regular working days vs. national public holidays vs. Saturdays and Sundays), and presence or absence of COVID-19 restrictions. We also recorded the temperatures of each day. Cases were subdivided into three groups: cases without significant injuries (Group A), cases with isolated bone fractures, major tears or articular dislocations (Group B1), and polytrauma (Group B2). Results: Higher temperatures were associated with a significant increase in overall ER visits, isolated injuries, and polytrauma. Sunny or cloudy days had a significantly higher number of patients with all injury types compared to rainy or stormy days. Weekends saw a significant decrease in overall admissions and isolated injuries but a higher rate of polytrauma compared to weekdays. National holidays had a significantly lower number of admissions for all injury types compared to weekdays. Restrictions due to the pandemic significantly reduced overall ER visits. Conclusion: Temperatures, meteorological factors, and national holidays could vary the workloads in the orthopedic ER of a European third-level trauma center.

Objective: The purpose of this study is to investigate the outcomes of the use of a 2.7 mm semitubular hook plate for internal fixation of unstable metaphyseal ulnar fractures. Methods: Between January 2015 and July 2019, 30 consecutive patients with a recent unstable distal ulnar fracture were included in this prospective case series. All patients were subjected to follow-up with the time of union, range of motion, pain using a Visual Analog Scale (VAS), and radiological and functional outcome using the quick Disabilities of the Arm, Shoulder, and Hand (DASH) score and Mayo wrist score after 12 months. Results: The mean age of the patients was 45.3 ± 10 years. There were 18 males (60%) and 12 females (40%), and there were 16 patients associated with distal radius fractures (53.33%). According to the AO classification of distal ulnar fractures, 3 fractures were type A2.1 (10%), 9 were type A2.2 (30%), 8 fractures were type A2.3 (26.67%), and 10 fractures were type A3 (33.33%). All fractures have been united with a mean duration of 9 ± 1.4 weeks, the mean supination was 81.4° ± 3.5°, the mean pronation was 81.3° ± 4.5°, the mean flexion was = 71.7° ± 3.6°, and the mean extension was = 81.7° ± 3.4°. The mean VAS was 1.1 ± 1 points, the mean DASH score was 9.3 ± 5.6 points, and the mean Mayo wrist score was 88.5 ± 7.2 points; 17 patients were excellent (56.67%) and 10 patients were good (33.33%) while 3 patients had satisfactory outcome (10%). Conclusion: Using the 2.7 mm semitubular hook plate is a successful choice for internal fixation of unstable distal ulnar fractures isolated or associated with distal radius fractures with a favorable union time, functional outcome, and range of motion with minimal complications.

Platelet-rich plasma (PRP) is gaining popularity across various medical fields, including orthopedics, for its potential in tissue regeneration and wound healing. As intra-articular treatments evolve, PRP has emerged as a promising option for managing knee osteoarthritis, meniscus, and ligament injuries. This review aims to provide an update on the current applications of PRP in treating knee osteoarthritis and its clinical implications in orthopedic and sports medicine. We reviewed 180 eligible studies, and our findings suggest that PRP injections significantly improve knee joint function compared to alternative treatments. The use of PRP across various medical fields has been growing in popularity recently. PRP is a biological product derived from the plasma portion of a patient's own blood, containing a higher concentration of platelets than normal. Its potential for tissue regeneration and wound healing has drawn significant attention from orthopedic surgeons, especially as intra-articular treatment options continue to evolve. The benefits of PRP in treating various osteoarticular conditions have sparked considerable interest within the orthopedic community, particularly for managing knee osteoarthritis, meniscus tears, and ligament injuries. This review aims to provide an updated overview of the current applications of PRP in the treatment of knee osteoarthritis and to offer clinical insights into its use in orthopedic and sports medicine practices. We reviewed 180 relevant titles and abstracts that met the inclusion criteria. Compared to other treatment options, PRP injections significantly enhance knee joint function.

Background: The development of less invasive all-inside techniques regarding anterior cruciate ligament (ACL) reconstruction surgery has been associated with various advantages, including fewer complications and reduced postoperative pain. Silva et al. described a quadruple semitendinosus graft construct and suspensory button fixation for ACL reconstruction as an alternative technique. At the end of this technique, the tibial tunnel is filled with a bone autograft plug. This paper aims to examine the incorporation of the autograft and thus evaluate whether the "Silva technique" provides the same benefits as all-inside techniques. Methods: A prospective study assessed 31 patients undergoing ACL reconstruction surgery using the "Silva technique." The cases involved in the study were skeletally mature patients with no previous history of ACL surgery or multiligamentous instability. All patients followed the same rehabilitation program and were examined at three standardized follow-up visits: 4 months, 8 months, and 1 year postoperatively. Tegner-Lysholm knee score (TLKS), visual analog score (VAS) for pain, and the IKDC subjective knee score were completed at every visit. A knee MRI scan was performed at every scheduled visit to assess bone graft incorporation and remodeling. Results: TLKS scores revealed a considerable improvement compared to preoperative figures, from 57.2 points preoperatively to an average of 99.4 at the 12-month follow-up (p < 0.0001). VAS scores were substantially ameliorated after the operation and until the second follow-up visit, from 5 before surgery to zero 8 months after the operation, with no noteworthy alterations afterward (p < 0.0001). IKDC subjective knee score outcomes were found to have increased at the last follow-up, from 59.3 prior to surgery to 99.8 12 months postoperatively (p < 0.0001). Regarding the MRI features of the bone autograft, the tibial tunnel was entirely filled by bone formation at the last MRI scan, suggesting complete integration of the autograft in all patients. Conclusions: Bone autograft employed to seal the tibial tunnel was completely incorporated in all cases 1 year postoperatively. The "Silva technique" appears to feature all the avails of all-inside techniques, whilst it seems to be simpler and easier than them after the surgeon is familiarized with its particular aspects. It is a robust option in orthopedic surgeons' arsenal. However, further large-scale pertinent research is requisite to confirm the findings of this study.

Background and Purpose: Revision total hip arthroplasty (rTHA) is a challenging procedure especially in the presence of severe bone loss where implant fixation is compromised. The aim of this study was to evaluate implant survival, clinical outcome, and midterm results in a group of complex patients after femoral revision using an uncemented modular implant design. Patients and Methods: We performed a retrospective study including 100 patients (101 hips) treated with revision THA using an uncemented modular implant design. We identified 51 hips as Paprosky types I-II and 50 hips as Paprosky III-IV bone defects. We reviewed operative reports and radiographs. Patients underwent a clinical examination to assess the Harris Hip Score (HHS) and completed patient-reported outcome measures (PROM), including the Oxford Hip Score (OHS) and the EQ-5D Visual Analog Scale (VAS). Minimum follow-up was 2 years (average, 5.8 years; range, 2.0-9.4 years). Results: Among the cases, 46 hips were revised for infection in a 2-stage procedure and 44 hips for aseptic loosening. 11 hips had periprosthetic fractures of Vancouver type B2 or B3. A total of 5 hips required revision with removal of the femoral implant and 11 patients experienced complications resulting in fracture (n = 1), dislocation (n = 10), and soft tissue revision (n = 1). The 5-year implant survival estimated by Kaplan-Meier survival analysis was 95% (95%-CI: 91%-99%). All hips had radiographic evidence of osseointegration and no one with subsidence greater than 5 mm. Additionally, 80% showed radiographic evidence of restoration of proximal femoral bone. Mean HHS was 78. Conclusion: In complex cases of revision THA, using a modular revision femoral system yielded promising results. The 5-year implant survival estimated by Kaplan-Meier survival analysis was 95% (95%-CI: 91%-99%), with all hips demonstrating radiographic evidence of osseointegration and no one with subsidence greater than 5 mm. Notably 80% showed radiographic evidence of restoration of proximal femoral bone.

Previous studies have shown that the use of nonsteroidal anti-inflammatory drugs (NSAIDs) is associated with increased stress fracture risk. This phenomenon has been studied predominantly in high-activity individuals, so data regarding the general population are limited despite the substantial economic and resource burden of stress fracture injuries within the general US population. Furthermore, our preclinical studies demonstrate that regular use of NSAIDs also diminishes the intrinsic ability of bone to resist fracture. To determine the association of regular NSAID use with stress fractures in the general population, we surveyed subjects presenting with either stress fracture or uncomplicated ankle sprain to assess their use of NSAIDs over the three months before their injury. We hypothesized that subjects with stress fractures would have increased regular NSAID usage as compared to controls. Subjects diagnosed with a stress fracture (n = 56) and subjects with uncomplicated ankle sprains (n = 51; control) were surveyed about their NSAID use at the time of their diagnosis and in the previous three months using a questionnaire based on the National Health and Nutrition Examination Survey (NHANES). Subjects were surveyed in person on the day of their injury diagnosis or by phone within 30 days of their diagnosis. Fisher's exact test was used to determine significant differences in NSAID usage between stress fracture and control subjects. Subjects diagnosed with stress fractures had a statistically significant increase in both current use (p=0.03) and regular use (p=0.04) of ibuprofen/naproxen/celecoxib as compared to control subjects. There were no significant differences in the use of aspirin, acetaminophen, or prescription medications containing acetaminophen between groups. Consistent with previous clinical reports, we observed a strong correlation between regular ibuprofen/naproxen/celecoxib use and stress fracture incidence in the general population. These results indicate that patients at high risk of stress fracture should avoid regular use of ibuprofen, naproxen, or celecoxib.

In this review paper, we present the common etiology, presentation, diagnosis, and management of the following three common bunion formations: dorsal bunion, tailor's bunion, and hallux valgus (HV). Bunions are common pathologies that present to a variety of clinics, so it is important for providers to have a base understanding of these in order to provide the best care to patients. Many of these bunion formations have a variety of causes which allow providers to manage them before surgical intervention is required. The aim of this review paper is to bring attention and expanded insight on these common bunion presentations in order to minimize morbidity early on. The information provided in this review will allow both primary care and subspecialty physicians with the knowledge to accurately diagnose and optimally manage these bony deformities of the lower extremity.

Introduction: Brachial plexus injuries (BPI) from gunshot injuries are uncommon but usually severe and can cause chronic pain, loss of function, and permanent nerve damage. Multiple surgical techniques including neurolysis, end-to-end suture repair, and graft repair have been described for the treatment of these injuries. However, surgical indication, timing, and technique for these injuries remain controversial. This systematic review aims to investigate the treatment modalities for patients with BPI due to gunshot-related injuries.

Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analysis (PRISMA) methodology was employed for this review. PubMed, Cochrane Reviews, Embase, and CINAHL databases were included. The following keywords constituted our search criteria: gun-shot-wounds, brachial plexus, traum^∗, and management.

Results: A total of 90 studies were imported for screening, from which 9 papers met our final inclusion/exclusion criteria. The most common studies utilized in this review were retrospective chart reviews followed by case series. In total, there were 628 patients that suffered from gunshot wounds to the brachial plexus. Most patients underwent some form of delayed nerve repair consisting of neurolysis, end-to-end epineural repair, or graft repair with a sural or antebrachial cutaneous nerve graft. Several patients suffered from complications, with neuroma being the most common long-term complication that required reoperation.

Conclusion: The optimal timing for surgeries involving BPIs should be determined after examining the level of nerve damage, associated injuries, operative risks, and electrophysiological workup for indications of spontaneous regeneration. Early surgical interventions were indicated for patients presenting with associated vascular or thoracic injuries, compressive masses, and nerve transection by sharp instruments in most selected papers.
