Incidence and Risk Factors of Infection After Fracture Fixation: A Multicenter Cohort Study.

Infection after fracture fixation (IAFF) is a severe complication. There are few multicenter studies targeting IAFF. This paper identifies independent risk factors associated with IAFF by analyzing multicenter clinical data. Appropriate interventions should be implemented to reduce the risk of IAFF. This is a multicenter retrospective cohort study. This study screened medical records of patients who underwent internal fixation for fractures at participating medical institutions from January 1, 2011, to December 31, 2020. Data extraction included demographic characteristics, disease features, surgical variables, and laboratory indicators. Logistic regression analysis was employed to identify the relationship between relevant risk factors and IAFF. Research data were sourced from the hospital's electronic medical record system and self-constructed databases. In our study, 202 patients who underwent internal fixation for fractures experienced postoperative infections, which corresponds to an overall incidence rate of approximately 1.7%. The predominant pathogen identified in these infections was Staphylococcus aureus. A multifactorial analysis indicated that several factors were independently associated with the occurrence of IAFF. These factors included BMI ranges of 24.0-27.9 and 28.0-31.9, smoking, a high ASA score, high-energy trauma, diabetes, open fracture, seasonal timing of the surgery (summer), bone grafting, drainage duration, surgical duration ≥ 180 min, and A/G ratio < 1.2. We strongly recommend that orthopedic surgeons perform comprehensive preoperative assessments on fracture patients to identify factors that may increase the risk of infection. Through the implementation of targeted interventions and beneficial modifications to these modifiable risk factors, it is possible to lower the incidence of IAFF. Additionally, proactive screening, risk stratification, and thorough patient education should be prioritized for patients with high risk but nonmodifiable factors.

Multicenter Randomized Clinical Trial of Highly Cross-Linked Polyethylene Versus Conventional Polyethylene in 518 Primary TKAs at 10 Years

Background: Second-generation highly cross-linked polyethylene (HXLPE) has revolutionized total hip arthroplasty. However, the long-term risks and benefits of HXLPE in primary total knee arthroplasty (TKA) remain unknown. This randomized clinical trial evaluated implant survivorship, complications, radiographic results, and clinical outcomes of HXLPE and conventional ultra-high molecular weight polyethylene (UHMWPE) inserts in primary TKAs. Methods: We enrolled 518 patients (518 knees) who underwent primary TKA in 3 centers within 1 tertiary referral network. The mean age was 67 years, the mean body mass index was 32 kg/m2, and 58% of the patients were women. All of the patients underwent primary TKA with a cemented posterior-stabilized tibial insert and patellar resurfacing. Randomization proceeded via stratified dynamic allocation. The patients were blinded to their study group allocation: those in the control group (254 knees) underwent TKA with an UHMWPE insert (N2Vac; Stryker); those in the treatment group (264 knees) received an HXLPE insert (X3; Stryker). Kaplan-Meier survivorship, radiographic results, and clinical outcomes were assessed. This trial was registered with ClinicalTrials.gov. The mean follow-up was 11 years. Results: The 10-year overall survivorship free from any revision and from any reoperation was 96% and 94%, respectively. There were no differences in the risk of revision or reoperation between the groups (p &gt; 0.05). There were a total of 19 revisions. Revision indications included periprosthetic joint infection (14 knees), instability (4 knees), and open reduction and internal fixation (ORIF) for a patellar fracture due to osteolysis around a UHMWPE insert (1 knee). There were no revisions due to polyethylene wear, osteolysis, or fracture of the post in the HXLPE group. The radiographic results and clinical outcomes were otherwise similar. Conclusions: Notably, no wear-related failures were identified in the HXLPE group, but there was 1 case of osteolysis in the UHMWPE group. Level of Evidence: Therapeutic Level I.

Plastic Surgery Contributions to the World Wars: Historical Foundations for Modern Craniofacial Techniques.

Plastic surgery played a crucial role during the World Wars. Surgeons dedicated their careers to reconstructing facial injuries and residual deformities incurred during combat. Times of unprecedented trauma led to rapid innovation in plastic surgery, with invaluable impact on practice today. Pioneers such as Harold Gillies are well-known for their work. There are numerous additional contributors who deserve wider recognition. A literature review was performed to identify key surgeons who treated soldiers' craniofacial injuries during World Wars I and II. Biographical information, country of practice, and technical contributions to plastic surgery were compiled. Nineteen plastic surgeons were identified who contributed significantly to craniofacial surgery during the World Wars. These surgeons were: Albéric Pont, Archibald Mcindoe, Arthur Mowlem, Harold Gillies, Hippolyte Morestin, James Barrett Brown, Jaques Joseph, Johannes Esser, John Staige Davis, John Reese, Otto Lanz, Paul Tessier, Robert Ivy, Suzanne Blanche Gros Noël, Thomas Kilner, William Kelsy Fry, Varaztad H. Kazanjian, Vilray P. Blair, and Vladimir Petrovich Filatov. Fourteen were active during WWI. Nine were active during WWII. Notable technical developments were made in maxillofacial fracture fixation, bone grafting, rhinoplasty, dental prosthetics, flap-based coverage, skin grafting, and burn reconstruction. Plastic surgeons played an unheralded role in managing the disfiguring craniofacial injuries of World Wars I and II. By treating tens of thousands of war victims, these surgeons contributed not only to the rehabilitation of soldiers but also to the advancement of craniofacial surgery and the establishment of plastic surgery as a distinct subspecialty.

Anterior Approach for Fixation of Acetabular Fractures Using Anatomically Designed Plates: Maintenance of Reduction and Functional Outcomes at a Minimum Five-Year Follow-Up

Is partial excision of the radial head safe and effective in all-arthroscopic treatment of terrible triad fractures?

Background: Our study aimed to evaluate the clinical and radiologic results of all-arthroscopic treatment of terrible triad injuries followed-up for a minimum of 5 years and investigate how arthroscopic partial excision for radial head fractures affects the results at the final follow-up.Methods: We retrospectively reviewed consecutive patients with terrible triad injuries who underwent all-arthroscopic treatment between January 2011 and June 2018. In group I, we performed conservative or arthroscopic fixation of stable radial head fractures, while in group II, arthroscopic partial excision of unstable radial head fractures involving &lt;30%–50% of the articular surface area was performed. Clinical outcomes were measured by visual analog scale score and assessment of instability, range of motion (ROM), and Mayo Elbow Performance Score. Radiological outcomes were evaluated using x-rays, and the integrity of the repaired lateral collateral ligament complex was confirmed through magnetic resonance imaging.Results: Thirty-two patients with an average age of 49.5±16.2 years met the inclusion criteria and were followed-up for a mean of 82.7±22.2 months. Twenty patients were assigned to group I and 12 patients to group II. Clinical outcomes showed no significant differences between the two groups at the final follow-up (P&gt;0.05). On radiological evaluation, more heterotopic ossifications were found in the radial head excision group (group II, 66.7% versus group I, 35%, P=0.02); however, there was no significant difference in ROM between the two groups (P&gt;0.05).Conclusions: In all-arthroscopic treatment of terrible triad injuries, arthroscopic partial excision of the radial head did not seem to have a significant impact on elbow joint stability.Level of evidence: III.

The effect of pin distractor assistance on the reduction of fibular fractures in the treatment of ankle fracture: A retrospective case-control study.

This study will evaluate the therapeutic effect of pin distractor assisted reduction of fibular fracture on ankle fracture. A retrospective analysis was performed on 98 patients diagnosed as ankle fracture or pilon fracture. These patients were all combined with fibular fracture. Retrospective analysis included 48 patients in the experimental group (distractor assisted reduction) and 48 patients in the control group (without pin distractor). The statistical indexes include: the time spent in fracture reduction and fixation, the length of surgical incision, the operative blood loss of fracture operation, the incidence of incision skin necrosis, the incidence of fracture end splitting during reduction, the quality of fracture reduction, the time of fracture healing, infection rate, and The American Orthopedic Foot and Ankle Society score at the last follow-up. There were statistical differences between the 2 groups in the time spent in the reduction and fixation of fractures, the incidence of fracture end splitting during reduction, the quality of anatomical reduction of fractures, and the healing time of fractures. The experimental group was better than the control group. In addition, for patients with long spiral fracture, comminuted fracture, osteoporotic fracture and preoperative delay time for operation more than 2 weeks, the time spent in the reduction and fixation of fracture, the operative blood loss of fracture operation, the incidence of fracture end splitting during reduction, the quality of anatomical reduction of fracture, and the healing time of fracture in the experimental group are also better than those in the control group. The pin distractor assisted reduction of fibular fracture has the advantages of simple operation, less trauma, short operation time, less operative blood loss, and fewer complications. It is especially suitable for patients with long spiral fibular fracture, comminuted fracture, osteoporotic fracture, and long preoperative delay time in ankle fracture.

Comparison of Elective Implant Removal and Complication Rates between Mini and Small Fragment Implants for Lateral Malleolar Fixation

IntroductionImplant removal after open reduction and internal fixation (ORIF) of ankle fractures is common. Mini-fragment implants have gained popularity for their smaller size, with studies showing similar load to failure to small-fragment implants. We hypothesized mini-fragment implant use for ORIF of the distal fibula is associated with a lower implant removal rate and without an increase in implant failure. MethodsIn this retrospective review study at two level-one trauma centers, adult patients (>18 years) with a lateral malleolar or bimalleolar fracture were included. Chart review was performed to determine if patients received ORIF of the distal fibula with mini-fragment implants or small-fragment implants. The primary outcome was elective implant removal of the fibular plate. Secondary outcomes included complications requiring reoperation. ResultsFive-hundred and five patients were included with a mean age of 50.6 ± 17.8 years old with a mean follow-up of was 75.7 ± 61.0 weeks. Sixty patients (11.9%) received mini-fragment fixation. The rate of elective distal fibula implant removal for the mini-fragment group was 8.3% (5 of 60) compared to 10.8% (48 of 445) in the small-fragment group (p= .66). The complication rate was 6.7% (4 of 60) for the mini fragment group versus 6.5% (29 of 445) for the small fragment group (p=1.00). Logistic regression demonstrated that each additional week of follow-up increased the implant removal rate with the observed odd ratio (OR) of 1.007 (95% CI 1.002-1.012). ConclusionElective implant removal rates and complications requiring reoperation were similar between mini-fragment and small-fragment fixation of distal fibula fractures. The hypothetical benefit of low-profile mini-fragment implants should be balanced with the higher implant cost.

A Retrospective Study of Ballistic Pelvic Fractures With Focus on Short-Term Clinical Outcomes.

To evaluate the orthopaedic management, associated injuries, and outcomes in patients treated for low-velocity ballistic pelvic fractures. Retrospective chart review. Single, urban, Level I trauma center. Patients 15 years or older treated for low-velocity ballistic pelvic (OTA/AO 61 and 62) fractures from May 2018 to August 2021. Primary study measures included pelvic fracture location, concomitant associated injuries, surgical interventions, and antibiotic treatment. Postinjury sequelae evaluated include infection, neurologic deficit, and need for orthopaedic removal of foreign body. Risk factors of postinjury sequelae were investigated. A total of 156 patients with ballistic pelvic fractures were included. The cohort consisted of 135 (86.5%) male patients with a mean age of 29.8 years. One hundred ten (70.5%) patients sustained 2 or more gunshot wounds. Ninety-eight (62.8%) patients underwent an exploratory laparotomy with 79 (50.6%) having a confirmed concomitant intestinal injury. Additional associated injuries included nerve injury (13.5%), vascular injury requiring repair or embolization (10.9%), and bladder injury (10.3%). Nine (5.7%) patients underwent orthopaedic operative management-five (3.2%) patients for operative fixation and 4 (2.5%) patients for removal of intra-articular foreign bodies. Diabetes (odds ratio [OR]: 33.1, P = 0.025), neurologic deficit on presentation (OR: 525.2, P < 0.001), vascular injury requiring repair or embolization (OR: 8.7, P = 0.033), and orthopaedic pelvic fixation (OR: 163.5, P = 0.004) were positively associated with the defined postinjury sequelae at 30 and 90 days of follow-up. There was not a statistically significant association between infection and retained foreign body (OR: 3.95 [95% CI 0.3-58.7, P = 0.318]) or bowel contamination (OR: 6.91 [95% CI 0.4-58.7, P = 0.178]). Ballistic fractures of the pelvis and acetabulum rarely required operative fixation (3.2%) or irrigation and debridement. Neither retained foreign body nor presumed bowel contamination of pelvic fractures had a statistically significant association with infection, which further supports conservative management of these injuries. Patients with diabetes, neurologic deficit on presentation, vascular injury necessitating intervention, and orthopaedic fixation of pelvic fracture are associated with increased risk of postinjury sequelae. Prognostic Level III. See Instructions for Authors for a complete description of levels of evidence.

Total knee arthroplasty combined with simultaneous open reduction and internal fixation in the treatment of knee osteoarthritis with patellar fracture: a case report and review of the literature

BackgroundPatients with severe knee osteoarthritis combined with patellar fracture are rare, and it is unclear whether single-stage surgery affects the enhanced recovery after surgery.Case presentationThis case report describes two patients of Han nationality. A 69-year-old male patient was previously diagnosed with severe knee osteoarthritis of the left knee joint and was treated conservatively with long-term oral nonsteroidal antiinflammatory drugs and intraarticular injection of sodium hyaluronate. He was hospitalized for acute left knee injury owing to a fall from a height. He was diagnosed with knee osteoarthritis of the left knee joint and patellar fracture. Another 74-year-old female patient was previously diagnosed with severe knee osteoarthritis, long-term oral nonsteroidal antiinflammatory drugs and topical Chinese medicine to relieve the pain. A month ago, she fell down the stairs and fractured the patella in her left knee, she was diagnosed with severe left knee osteoarthritis combined with an old left patella fracture. Both patients were successfully treated by single-stage primary total knee arthroplasty and fixation of the patellar fracture. They both carried out early functional exercise normally and successfully achieved enhanced recovery.ConclusionSuccessful single stage total knee replacement with patella management can not only reduce the number of operations, but also enable patients to achieve rapid postoperative recovery. However, single stage may increase the risk of local surgical complications. Therefore, for most patients, especially those with low risk of anesthesia related complications, standard of treatment remains first fixing the patellar fracture and when the fracture is healed proceed with the total knee arthroplasty.

Utilization of Surgical Fixation for Distal Radius Fractures in the United States: A Population-Based Cohort Study

In contrast to younger adult populations, clinical practice guidelines state that there is no difference in long-term functional outcomes in surgically versus nonoperatively treated distal radius fractures in patients ≥65 years old. In this study, we asked the following questions: (1) has treatment for distal radius fractures in younger and older adult populations changed over time? (2) What patient and surgeon factors are associated with treatment trends? Using a national administrative claims database, we identified patients aged ≥18 years with isolated, closed distal radius fractures, subdivided by age (18-64 years, ≥65 years old). We characterized the proportion of patients who underwent open reduction and internal fixation (ORIF) over time. We stratified our analysis by surgeon subspecialty, region, and mean area income. Changes in ORIF utilization over time were evaluated using linear regression models. The proportion of distal radius ORIF, including in patients aged ≥65 years, increased from 10.4% in 2012 to 15.1% in 2020. Of the ORIF procedures performed, hand surgeons accounted for an increasing proportion over time, with a corresponding decrease in those performed by general orthopedic surgeons. The proportion of ORIF increased over time in all US regions, with the largest rate of increase in the Midwest for patients aged ≥65 years and Northeast for patients aged 18-64 years. Patients living in areas with mean family income ≥$65,000 were more likely to undergo ORIF. The proportion of distal radius ORIF including in older adult populations is increasing in all US regions, and an increasing proportion is performed by hand surgeons. Further analysis of the drivers of these trends is warranted, given the rising incidence of surgical treatment in older patients, which could reflect evolving patient activity demands and suggest a need to further evaluate conventional treatment algorithms based on age.

Delayed fixation of distal radial fractures beyond three weeks after initial failed closed reduction increases the odds of reoperation.

We aimed to compare reoperations following distal radial fractures (DRFs) managed with early fixation versus delayed fixation following initial closed reduction (CR). We used administrative databases in Ontario, Canada, to identify DRF patients aged 18 years or older from 2003 to 2016. We used procedural and fee codes within 30 days to determine which patients underwent early fixation (≤ seven days) or delayed fixation following CR. We grouped patients in the delayed group by their time to definitive fixation (eight to 14 days, 15 to 21 days, and 22 to 30 days). We used intervention and diagnostic codes to identify reoperations within two years. We used multivariable regression to compare the association between early versus delayed fixation and reoperation for all patients and stratified by age (18 to 60 years and > 60 years). We identified 14,960 DRF patients, 8,339 (55.7%) of whom underwent early surgical fixation (mean 2.9 days (SD 1.8)). In contrast, 4,042 patients (27.0%) underwent delayed fixation between eight and 14 days (mean 10.2 days (SD 2.2)), 1,892 (12.7%) between 14 and 21 days (mean 17.5 days (SD 1.9)) and 687 (4.6%) > 21 days (mean 24.8 days (SD 2.4)) post-fracture. Patients who underwent delayed fixation > 21 days post-fracture had a higher odds of reoperation (odds ratio (OR) 1.33 (95% CI 1.11 to 1.79) vs early fixation). This worsened for patients aged > 60 years (OR 1.69 (95% CI 1.11 to 2.79)). We found no difference in the odds of reoperation for patients who underwent delayed fixation within eight to 14 or 15 to 21 days post-fracture (vs early fixation). These data suggest that DRF patients with fractures with unacceptable reduction following CR should be managed within three weeks to avoid detrimental outcomes. Prospective studies are required to confirm these findings.

Biomechanical Analysis of a Modified Triangular Osteosynthesis Technique for Treatment of Spinopelvic Dissociation.

The purpose of this study was to evaluate the biomechanical stability of a modified triangular osteosynthesis construct with S1 pedicle screws compared with other described lumbopelvic fixation constructs in a U-type sacral fracture model. U-type sacral fractures were created in validated fourth-generation spinopelvic models. Four different constructs were cyclically loaded with displacement measured in all planes: (1) bilateral L5 pedicle screws with rods attached to iliac bolts, (2) bilateral L5 and S1 pedicle screws with rods attached to iliac bolts, (3) bilateral L5 pedicle screws with rods attached to iliac bolts with a transsacral-transiliac screw, and (4) bilateral L5 and S1 pedicle screws with rods attached to iliac bolts with a transsacral-transiliac screw. The bilateral L5 and S1 pedicle screws with rods attached to iliac bolts with a transsacral-transiliac screw construct had significantly decreased horizontal, vertical, and angular displacement compared with all other constructs. From a biomechanical perspective, a modified triangular osteosynthesis construct with S1 pedicle screws improves stability in fixation of U-type sacral fractures.

Development of a Surgical Difficulty Score for Open Reduction Internal Fixation of Pilon Fractures.

To identify characteristics that contribute to surgical complexity in pilon fractures and to develop a machine learning (ML) Pilon Surgical Difficulty Score (PSDS) based on these factors. Retrospective cohort study. Academic Level I trauma center. Pilon fractures (OTA/AO Type 43) in adult patients treated with open reduction internal fixation. Various patient, injury, and radiological characteristics were assessed. Surgical difficulty was measured using 2 outcomes: (1) operative time and (2) perceived difficulty. Perceived difficulty was determined using the opinion of 16 fellowship-trained orthopaedic traumatologists on a 10-point scale. Significant predictors of difficulty were determined using univariate analyses. ML models were used to develop a PSDS for both operative time and surgical difficulty. One hundred operatively fixed pilon fractures were included. Predictors of operative time were age, OTA/AO classification, articular comminution, articular impaction, bone loss, delay to surgery, poor quality reduction, number of approaches, and number of articular fragments. Predictors of perceived difficulty included OTA/AO classification and delay to surgery. Operative time PSDS had a mean absolute error of 64 minutes and a 60-minute buffer accuracy of 59%. Perceived difficulty PSDS had a mean absolute error of 1.7 points and a 2-point buffer accuracy of 63%. ML was used to generate accurate PSDSs for operative time and difficulty for pilon fractures. Future work should aim to clinically validate these PSDSs, so they may improve patient outcomes. Level III Diagnostic.

Open Reduction and Internal Fixation of Mandibular Condyle Fractures Using AUTOFIX 2.0® Cannulated Compression Screw System: A Technical Innovation with Intraoperative CT-Scan

Condylar process fractures remain a matter of ongoing controversy in maxillofacial surgery because of variety of opinions and proposed treatment modalities offered in the literature. The trend is toward open reduction and internal fixation (ORIF) whenever there is displacement or dislocation combined with unstable occlusal conditions. The fundamental treatment goals are anatomical fixation and early return to function. However, ORIF of a fractured condyle carries significant risks, including facial nerve damage, and presents challenges in reducing and stabilizing the fractured segment in an area of limited access. We present here an innovative technique for ORIF of condylar head fractures. It consists in fracture reduction and stabilization with two Kirschner wires followed by osteosynthesis with two cannulated headless compression screws using the AUTOFIX 2.0® system (Stryker, Kalamazoo, USA). This new technique, combined with intraoperative CT scan, ensures satisfactory reduction and stabilization of the dislocated joint segment, thereby restoring the condyle to its physiologically normal position.

The role of tranexamic acid for infection prevention after fracture fixation

Despite the measures employed, fracture-related infections remain a concern after fracture fixation worldwide. Recently, the role of tranexamic acid as a protective drug against postsurgical infections in joint replacement and orthopedic trauma surgery has been proposed, where tranexamic acid has been associated with less surgical wounds complications and infectious complications including periprosthetic joint infection. The mechanism through which tranexamic acid exerts a protective effect against peri-implant infection is still the subject of debate. Although some authors hypothesize an indirect effect inhibiting the formation of postoperative hematoma, there are several studies that show a direct antibacterial effect of the drug against the capacity of bacterial aggregation, even avoiding biofilm formation, favoring the immune response of the host and the action of antibiotics. The purpose of this narrative review is to show the current role of tranexamic acid in orthopedic trauma, specifically its relationship with the prevention of infections related to implants.

Predictors for 1-year mortality in geriatric patients following fragile intertrochanteric fracture surgery

ObjectiveTo investigate the risk factors influencing 1-year mortality after intramedullary nail fixation for fragile intertrochanteric fracture in elderly individuals.MethodsThe medical records of 622 consecutive elderly patients (aged ≥ 65 years) with fragile intertrochanteric fractures treated with proximal femoral nail anti-rotation (PFNA) and followed-up were retrospectively analyzed. The patients were divided into death and survival groups according to their survival status within 1 year after surgery, and the differences in age, sex, region of residence, tobacco use, alcohol use, body mass index (BMI), comorbidities (hypertension, diabetes mellitus, coronary heart disease, stroke, dementia, chronic obstructive pulmonary disease, pneumonia), preoperative hemoglobin, preoperative albumin, deep vein thrombosis, fracture type (AO classification), injury-to-surgery time, American Society of Anesthesiologists (ASA) score, anesthesia modality, duration of surgery, intraoperative blood loss, and blood transfusion were compared. The Kaplan–Meier method was used for univariate analysis to screen for statistically significant differences between the two groups, and the data were entered into the Cox proportional hazards model for multivariate analysis to determine independent risk factors affecting 1-year postoperative mortality. For subgroup analysis, we explored the varying effects of hypoproteinemia and being underweight in patients of different genders, as well as the effects of different age ranges, different injury-to-surgery times, and different blood transfusion volumes on 1-year postoperative mortality.ResultsThe mortality rates at 1, 3, and 6 months, and 1 year after surgery were 3.9%, 7.2%, 10.1%, and 15.3%, respectively. Univariate analysis showed that advanced age, male sex, tobacco use, underweight (BMI < 18.5), coronary heart disease, stroke, dementia, pneumonia, number of comorbidities ≥ 3, hypoproteinemia and injury-to-surgery time ≤ 2 days were associated with the 1-year postoperative survival status (P < 0.1). Multivariate analysis revealed that advanced age, male sex, dementia, number of comorbidities ≥ 3, hypoalbuminemia, and being underweight were independent risk factors for 1-year postoperative mortality. Subgroup analysis showed that being underweight was associated with 1-year postoperative mortality only in male patients but not in female patients, whereas hypoproteinemia was associated with 1-year postoperative mortality in both male and female patients. Furthermore, an injury-to-surgery time of less than 2 days improved patient survival, and patients more than 80 years old showed an elevated risk of postoperative mortality.ConclusionsPreoperative health status is a critical predictor of postoperative outcomes in elderly patients with fragile intertrochanteric fractures. Priority care should be given to the patients who are elderly, male, have dementia, have comorbidities, or are malnourished. Prompt nutritional reinforcement should be provided to patients with intertrochanteric fractures with comorbid hypoproteinemia and underweight. Furthermore, surgery should be performed as early as possible in patients with fewer comorbidities.

Early weight-bearing following distal femur fracture fixation - a systematic review and meta-analysis.

The global standard of care for hip fracture surgery is early weight-bearing, but this has not extended to other lower extremity fractures in the elderly. Patients undergoing fixation of distal femur fractures are often prescribed weight-bearing restrictions, which may lead to deconditioning and other complications. The purpose of this study was to compare the outcomes and complication rates between patients permitted early versus restricted weight-bearing following distal femur fracture fixation. Medline, Embase, Cochrane and Web of Science databases were searched for English language articles up to 21 October 2023, identifying 366 studies for screening. Comparative studies evaluating patients undergoing distal femur fracture fixation with early or restricted weight-bearing were included. Native knee and periprosthetic fractures were included. Ten studies were included for analysis. Two studies provided Level II evidence, while the remaining eight studies provided Level III evidence. Cochrane risk of bias tools were utilized to assess study quality. Revision and complication rates were analyzed and reported as odds ratio. Sub-analysis was undertaken to address the heterogeneity in author definitions of weight-bearing. There was no statistically significant difference in the revision or complication rate between the two groups. Early weight-bearing following distal femur fracture fixation in a predominantly elderly population does not demonstrate an increased rate of revision or complications compared to restricted weight-bearing. However, there are limitations to the available literature, and the strength of the findings is insufficient to provide strong recommendations for all patients. Future studies should employ standardized definitions and avoid partial or time-based restrictions.

Single-Stage Conversion of External Fixation into Internal Fixation for Compound Fractures in War-Wounded Patients: A Cohort Study in Iraq

Background: War-induced. Compound fractures cause considerable damage to the limbs, affecting mobility and quality of life; surgeons consider managing compound fractures to be a difficulty. Although multi-stage conversion from external to internal fixation is still common, multiple studies worldwide are promoting single-stage conversion. Objective: To assess the efficacy and safety of a single-stage conversion from external to internal fixation using the functional results of many Iraqi war wounded patients who were initially treated with external fixation. Methods: A retrospective cohort study analyzed the data of 40 war-wounded patients (39 males and 1 female) ranging in age from 18 to 50 years. All patients came with war-related complex fractures, which were stabilized and referred for external fixation. Following a single-stage conversion to internal fixation, the patients were followed up to assess the functional outcomes of this approach using Ketenjian's functional criteria. Results: A study of 40 patients (45 limbs), mostly male (97.8%), demonstrated a statistically significant link between non-union and time to convert from external to internal fixation. However, fracture type, Gustilo categorization, fixation method, and complication rates had no significant impact on Ketenjian's score results. Conclusions: The single-staged external to internal fixation conversion is regarded as a safe and reliable procedure with good overall functional outcomes; it could be performed by experienced surgeons instead of two-staged conversions, taking into account the patient's general health and the state of the local soft tissue.

Robot-assisted percutaneous scaphoid fixation: patient-reported outcomes and learning curve at two centres.

This study describes patient-reported outcomes of robot-assisted percutaneous scaphoid fracture fixation of 62 patients from two medical centres and the learning curve of this new technique. One attempt to place the guidewire was sufficient in 97% of cases. All fractures achieved radiographic union at a mean of 9 weeks. There were no complications observed. At a mean follow-up of 36 months (range 12-68 months), the mean patient-rated wrist evaluation (PRWE) was 2 (range 0-22) and the mean Mayo Wrist Score was 96 (range 70-100). After the initial ten to 20 cases, the learning phase was reasonably surmountable with a marked reduction of operative duration and improvement of the screw accuracy.Level of evidence: IV.
