The duration of antibiotic therapy for fracture related infection does not affect recurrence but leads to increased adverse effects: a comparison among 6, 12 and 24 weeks of treatment.

PURPOSE: The optimal duration of antibiotic therapy for fracture-related infection (FRI) has not been well defined. Our aim was to assess the recurrence rate of infection in patients who underwent six, 12, or 24 weeks of antibiotic therapy following surgical treatment for FRI one year after antibiotic discontinuation. Additionally, complications were monitored. METHODS: Patients with FRI underwent surgical treatment, and antibiotic therapy was initiated. The patients were divided into groups at the 6th and 12th weeks of antibiotic therapy. The primary endpoint was the recurrence of deep or superficial infection at 90 days and one year after the end of antimicrobial therapy. RESULTS: There was no difference in the recurrence of infection 90 days or one year after stopping antibiotic therapy among patients treated for six, 12, or 24 weeks (p = 0.98 and p = 0.19, respectively). The overall recurrence rate of infection 90 days after stopping antibiotic therapy was 4.9% (8/163), and one year after discontinuation of antibiotic therapy was 9.8% (16/163). There was a statistically significant difference in the incidence of adverse effects among the three groups (chi-square; p = 0.01). Adverse effects were more common in the group treated for 24 weeks than in the groups treated for 6 weeks (z score, p = 0.017) or 12 weeks (z score, p = 0.005). CONCLUSION: Antibiotic therapy longer than 6 weeks did not reduce the recurrence of FRI after one year of follow-up. Additionally, antibiotic treatment for 24 weeks increases adverse events such as skin reactions and acute renal failure.

Peri-implant femoral fractures: Challenges, outcomes, and proposal of a treatment algorithm.

PURPOSE: Non-prosthetic peri-implant fractures are challenging injuries. Multiple factors must be carefully evaluated for an adequate therapeutic strategy, such as the state of bone healing, the type of implant, the time and performed personnel of previous surgery, and the stability of fixation. The aim of this study is to propose a rationale for the treatment. METHODS: The peri-implant femoral fractures (PIFFs) system, a therapeutic algorithm was developed for the management of all patients presenting a subtype A PIFF, based on the type of the original implant (extra- vs. intra-medullary), implant length and fracture location. The adequacy and reliability of the proposed algorithm and the fracture healing process were assessed at the last clinical follow-up using the Parker mobility score and radiological assessment, respectively. In addition, all complications were noticed. Continuous variables were expressed as mean and standard deviation, or median and range according to their distribution. Categorical variables were expressed as frequency and percentages. RESULTS: This is a retrospective case series of 33 PIFFs, and the mean post-operative Parker mobility score was (5.60 ± 2.54) points. Five patients (15.1%) achieved complete mobility without aids (9 points) and 1 (3.0%) patient was not able to walk. Two other patients (6.1%) were non-ambulatory prior to PPIF. The mean follow-up was (21.51 ± 9.12) months (range 6 - 48 months). There were 7 (21.2%) complications equally distributed between patients managed either with nailing or plating. There were no cases of nonunion or mechanical failure of the original implant. CONCLUSION: The proposed treatment algorithm shows adequate, reliable and straightforward to assist the orthopaedic trauma surgeon on the difficult decision-making process regarding the management of PIFF occurring in previously healed fractures. In addition, it may become a useful tool to optimize the use of the classification, thus potentially improving the outcomes and minimizing complications.

Open reduction and internal fixation of Ideberg type IA glenoid fractures: Tricks, pearls, and potential pitfalls based on a retrospective cohort of 33 patients focusing on the rehabilitation protocol.

INTRODUCTION: The standard treatment of anterior glenaoid fractures carrying > 20% of the glenoid fossa is open reduction and internal fixation (ORIF). In the herein study, we report our outcomes in a retrospective cohort of anterior and anteroinferior glenoid rim fractures using an accelerated postoperative rehabilitation protocol. A secondary aim is to describe the surgical steps for ORIF of anterior and anteroinferior glenoid rim fractures using the anterior axillary approach, describing the tricks, pearls, and pitfalls of this surgical technique. METHODS: A retrospective cohort of skeletally mature patients treated for an anterior glenoid rim fracture carrying > 20% of the glenoid fossa during a 10-year period were operated on using a vertical axillary incision, osteosynthesis with 2.0-mm cortical screws, and labral repair with small diameter metallic anchors and non-absorbable sutures. Rehabilitation began on the first postoperative day, including passive external rotation exercises and active-assisted flexion, adduction, and abduction exercises as tolerated. The exercises are performed with the patient sitting or lying down. Phase 1 is continued for 6-10 weeks until the patient regains painless, normal, or near-normal ROM. Usually by 10 weeks, the fracture and labrum are healed, so phase 2 rehabilitation begins with strengthening and ROM exercises. Radiologic and clinical outcomes, including active range of motion (ROM), glenohumeral stability, and visual analogue scale (VAS) were measured. RESULTS: About 33 patients (35 fractures) had complete medical records and pre- and post-operative imaging exams available for further analysis regarding the surgical protocol, with a mean of 4.8 years. The mean DASH questionnaire was 3.75 ± 9.0 and the mean CM score was 62.5 ± 0.1. Active flexion and internal rotation were recovered in all patients, while external rotation presented an average loss of 8° (p = 0.12) and abduction of 5° (p = 0.33). The mean VAS was 1.1 ± 0.8. No patient reported major or disabling symptoms, or great difficulty or inability to perform daily or recreational activities. No patient presented residual instability of the glenohumeral joint. CONCLUSION: In this retrospective cohort, ORIF using a vertical axillary incision, osteosynthesis with 2.0-mm screws, and labral repair with small diameter metallic anchors and non-absorbable sutures was a safe approach, with a minimal risk of complications and residual instability. The accelerated postoperative rehabilitation protocol, allowing immediate passive external rotation of the operated shoulder, resulted in a non-significant loss of ROM compared to the contralateral side. Therefore, we recommend this management strategy for anterior glenoid rim fractures in patients with unstable shoulder joint after traumatic glenohumeral dislocation. LEVEL OF EVIDENCE IV: Therapeutic Study (Surgical technique and Retrospective cohort).

Can CT-based assessment of lateral malleolus anatomy indicate when and how to perform an intramedullary fixation in distal fibula fractures? An analysis of 150 ankles.

PURPOSE: The primary aim was to analyse the lateral malleolus morphology with a focus on the shape of the distal fibula for IM fixation of the fibula in infra- and transsyndesmotic fracture patterns. The secondary aim was to propose a treatment algorithm according to the lateral malleolar anatomy. METHODS: 77 healthy, skeletally mature volunteers underwent CT scanning of the ankle. The fibula medullary canal and its cortical thickness were quantitatively analysed at 4 different levels measured from the fibular tip (1.5 cm, 3.0 cm, 4.5 cm, and 6.0 cm). A geometric classification was proposed, and a decision algorithm was developed. Statistical significance was set at a p-value < 0.05. RESULTS: The smallest diameter of the medullary canal of the fibula was at 6.0 cm from the tip of the fibula, in 98.2% of the ankles. The distal fibula can be classified into triangular and rectangular type, according to the cortical thickness index (p < 0.0001). In 16.7% ankles, the internal diameter of the fibula at 6.0 cm was equal or narrower than 3.5 mm (p < 0.05). CONCLUSION: The shape of the distal fibula as evaluated by CT-guided analysis allows for IM osteosynthesis of the lateral malleolus in 83% of individuals. In our study, the smallest diameter of the medullary canal of the fibula was located 6.0 cm from the tip of the lateral malleolus. Coronal CT evaluation is advantageous in indicating which type of IM implant should be used safely for infra- and transsyndesmotic fracture patterns, potentially reducing intraoperative risks.

Computed Tomography Does Not Improve Intra- and Interobserver Agreement of Hertel Radiographic Prognostic Criteria.

Background and Objectives: Proximal humerus fractures are the second most frequent site of avascular necrosis (AVN), occurring in up to 16% of cases. The Hertel criteria have been used as a reference for the prediction of humerus head ischemia. However, these are based solely on the use of radiographs, which can make interpretation extremely difficult due to several reasons, such as the overlapping fragments, severity of the injury, and noncompliant acute pain patients. The objectives of the study were to evaluate the role of computed tomography (CT) in the interpretation of the Hertel criteria and to evaluate the intra- and interobserver agreement of orthopedic surgeons, comparing their area of expertise. Materials and Methods: The radiographs and CT scans of 20 skeletally mature patients who had fractures of the proximal humerus were converted to jpeg and mov, respectively. All images were evaluated by eight orthopedic surgeons (four trauma surgeons and four shoulder surgeons) in two different occasions. The intra- and interobserver agreement was assessed by using the Kappa coefficient. The level of significance was 5%. Results: There was a weak-to-moderate intraobserver agreement (κ < 0.59) for all examiners. Only the medial metaphyseal hinge greater than 2 mm was identified by 87.5% of evaluators both in the radiographic and CT examinations in the two rounds of the study (p < 0.05). There was no significant interobserver agreement (κ < 0.19), as it occurred only in some moments of the second round of evaluation. Conclusions: The prognostic criteria for humeral head ischemia evaluated in this study showed weak intra- and interobserver agreement in both the radiographic and tomographic evaluation. CT did not help surgeons in the primary interpretation of Hertel prognostic criteria used in this study when compared to the radiographic examination.

Limb Salvage after Lower-Leg Fracture and Popliteal Artery Transection-The Role of Vessel-First Strategy and Bone Fixation Using the Ilizarov External Fixator Device: A Case Report.

Open traumatic lesion of the popliteal artery is relatively rare. Ischemia time longer than 6 h and severity of limb ischemia have been shown to be associated with an increased risk of limb loss. Severe local infection is critical in the presence of major soft tissue trauma or open fractures. We report the case of a young female who suffered a traumatic transection of the popliteal artery associated with an open fracture of the distal tibia and fibula managed by direct vessel reconstruction with an end-to-end repair and skeletal stabilization initially with half-pin external fixation, then replaced by an Ilizarov circular frame. The patient had a very satisfactory outcome, but the fracture healed malunited, later corrected by open reduction and internal fixation with lag-screwing and a neutralization plate.

A short single-incision approach for antiglide plate fixation of oblique fractures of the lateral malleolus: a technical tip.

Displaced fractures (> 2 mm) of the lateral malleolus, without medial or syndesmotic injuries, are often the subject of controversy regarding the best treatment option. In the past, these fractures were usually treated conservatively using a cast for 6 to 8 weeks without weightbearing. Currently, most of the patients desire a quick return to their previous activities, what makes surgical treatment a reasonable choice. It has benefits as earlier ankle mobilization and weightbearing. It also restores ankle biomechanics, preventing secondary osteoarthritis. However, postoperative complications with the standard lateral incision exist such as implant discomfort, dehiscence and infection. Minimally invasive techniques have been described to help avoiding these complications. This technical note described a short single-incision approach for the surgical treatment of displaced oblique fibular fractures type AO/OTA 44-B1 with an antiglide plate that presents the advantage of less risk of damaging the soft tissues, periosteal stripping and disturbance of the fracture hematoma.

"Clothesline technique" for proximal tibial shaft fracture fixation using conventional intramedullary nail: a simple, useful, and inexpensive technique to prevent fracture malalignment.

Treatment of proximal tibial shaft fractures is always challenging. Despite the development of modern techniques, the literature still shows high complication rates, especially regarding proximal fragment malalignment. It is well known that knee position in flexion during tibial nailing is responsible for extension and valgus deformities of the proximal fragment. Unlike in tibial shaft fractures, nails do not reduce proximal tibial fractures due to the medullary canal width. This study aims to describe a simple, useful, and inexpensive technique to prevent valgus and extension deformities when treating proximal tibial fractures using conventional nails: the so-called clothesline technique.

Submuscular double bridge plating for complex distal fractures of the humerus: an alternative, safe, and efficient treatment method.

PURPOSE: The aim of our study is to show the functional outcomes and complication rates of humeral complex fractures in adults, using osteosynthesis with two bridging orthogonal submuscular plates. METHODS: The study consists of a prospective case series of 13 patients with isolated humeral complex fractures treated with two bridging orthogonal submuscular plates. Functional assessment was performed using disabilities of the arm, shoulder, and hand (DASH) score with 30 items. The age ranged from 22 to 68 years, with a mean age of 39 years. Functional assessment with DASH score was performed at the twelfth postoperative week. RESULTS: All patients presented fracture healing in the fourth postoperative month. Of the 13 patients, five (38%) had a DASH score of zero (best function possible). One patient developed neuropraxis and presented with a score of 100 (worst possible). One case developed superficial infection, which was treated with oral antibiotics and local debridement. CONCLUSIONS: This study demonstrated satisfactory functional outcome in patients with distal-third diaphyseal humeral complex fractures treated with two locked submuscular plates. The authors consider it as a safe method and an efficient alternative, especially in younger patients who require early functional recovery.

A survey to assess the educational-level interference on self-evaluation of acute pain.

OBJECTIVE: The present study aimed to evaluate whether patient education level interferes in the percentage of pain relief or increase using visual analogue scale (VAS) and subjective pain perception. PATIENTS AND METHODS: Ninety-five patients presenting acute shoulder pain due to enthesitis were evaluated. They were asked to quantify the pain using VAS before steroid articular infiltration. One week later, patients reevaluated the pain using VAS and orally stated the percentage of perceived pain increase or relief. The information gathered was then compared among three patient educational levels (elementary, high school, and university). RESULTS: Percentages of improvement stated orally and utilizing VAS presented no statistically significant differences among the three educational status levels (p = 0.804). CONCLUSION: Patient educational status caused no impact in the results of acute pain self-assessment with VAS and oral evaluation.

Proximal humeral fractures: an understanding of the ideal plate positioning.

PURPOSE: The present study aims to evaluate if the bicipital groove can be used as a parameter for ideal plate positioning in proximal humeral fixation applying locking compression plate. METHOD: The authors questioned whether the bicipital groove can be used as a parameter for ideal plate positioning applying locking compression plate for proximal humeral fractures. A method using the bicipital groove as the main parameter was developed using computed tomography scan (CT-scan). Seventy shoulders presenting fracture absence were used to calculate proper plate positioning, allowing the largest area for locked screw placement into the humeral head. Intraclass correlation coefficient and Bland and Altman graphics calculated intra-observer reliability for CT-scan evaluation. RESULTS: All observers presented satisfactory plate positioning using this method. The mean differences for observers were close to zero, suggesting high interobserver reproducibility. A significant (p <0.0001) intra-observer agreement existed for the three evaluators. Observer 2 agreement was the strongest (ICC = 0.98), showing almost perfect reproducibility measurement, followed by observer 3 (ICC = 0.84) with good reproducibility, and lastly observer 1 demonstrated moderate degree agreement (ICC = 0.47). CONCLUSION: Considering the CT-scan analysis, the bicipital groove can be used as a parameter for ideal plate positioning in proximal humeral fractures. This method demonstrated satisfactory intra-observer reproducibility. Adopting this method, longer and better distributed screw placement provides more stable fixation for proximal humeral fractures.

Minimally invasive percutaneous plate osteosynthesis for ankle fractures: a prospective observational cohort study.

BACKGROUND: The gold standard for the surgical management of ankle fractures is through open reduction and internal fixation. The rate of wound problems has been reported to be as high as 18%, especially in patients with poor vascular supply or in diabetics. Minimally invasive percutaneous plate osteosynthesis (MIPPO) has been described as a potential solution for these patients. PATIENTS AND METHODS: This is a prospective observational cohort study. From October 2009 to February 2010, and following ethical approval of our research, adult patients admitted at our level I trauma center with a closed lateral malleolar displaced unstable fracture (Lauge-Hansen supination-external rotation) with or without a medial-sided injury and patients with an undisplaced fracture associated with medial clear space opening on external rotation stress radiographs were recruited and managed using MIPPO technique. All patients were followed up for a minimum of 12 months post-surgery (12-20 with a mean of 16.5 months). Trauma mechanism, comorbidities, classifications, trauma-surgery interval, image intensifier duration, surgery duration, complications, and function American Orthopaedic Foot and Ankle Society (AOFAS) were analyzed. RESULTS: Thirty-two patients were recruited of which 20 fulfilled the inclusion criteria (16 females, 4 males) and were available for follow-up. Ten fractures (50%) were classified as 44-B1, 7 fractures (35%) as 44-B2, and 3 fractures (15%) as 44-B3 according to the Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association classification (100% were supination-external rotation injuries). At 8 weeks post-surgery, all fractures had healed. The duration of surgery ranged between 15 and 73 min (average 32.8) from skin incision to closure. There were 2 complications (1 malunion and 1 skin necrosis requiring implant removal). At 12-month follow-up, AOFAS average was 88.3 (72-100 standard deviation of 6.8 points). CONCLUSION: MIPPO technique proved to be a viable option for lateral malleolar fracture treatment with a low complication rate and high functional outcome at 1 year. It is particularly useful in patients with a high risk of wound complication.

Is just one screw really enough? Single- versus double-screw in the medial malleolus in supination-external rotation ankle fractures: A comparative biomechanical study using partially threaded cancellous screws.

OBJECTIVE: The aim of this study is to investigate stiffness and the maximum load to failure values of single- and double-screw fixation of oblique medial malleolus fractures using partially threaded cancellous screws. Our hypothesis is that single-screw fixation of medial malleolus fractures after SER injuries provides similar stiffness when compared with double-screw fixation. DESIGN: Biomechanical study. METHODS: Twelve composite polyurethane synthetic right distal tibiae were used in the experiment. Oblique fractures of the medial malleolus were created with a band saw using a custom-made osteotomy guide to standardize the cuts in all models. Bone models were randomly separated into two groups and fixed with one (n = 6) or two (n = 6) 4.0 mm partially threaded cancellous screws placed perpendicular to the fracture line. These were tested by applying an offset axial tension at 10 mm/minute up to maximum load displacement, defined as subsidence of the medial malleolus fragment. Maximum load to failure was determined for the groups at the point where the curve ceased to be linear and suffered an inflection. Force versus displacement curves were obtained and recorded. The student's t-test for independent samples was used to compare stiffness (N / mm) and maximum load (N) between experimental groups, with a p value of < 0.05. RESULTS: There were no significant differences in stiffness (p = 0.290) and maximum load (p = 0.191) among the two fixation constructs. Mean stiffness was 62.26 (±SD 21.11) N/mm for double-screw fixation group and 48.24 (±SD 22.40) N/mm for single-screw fixation group. Mean maximum load was 387.83 (±SD 115.78) N for double-screw fixation group and 306.64 (±SD 81.97) N for single-screw fixation group. CONCLUSION: Fixation with one 4.0 mm partially threaded cancellous screw was not shown to be biomechanically inferior to fixation with two 4.0 mm partially threaded cancellous screws in an oblique fracture of the medial malleolus, supporting previous clinical studies that have shown that one screw is sufficient for fractures of the medial malleolus.

Doctor, When Should I Start Walking? Revisiting Postoperative Rehabilitation and Weight-Bearing Protocols in Operatively Treated Acetabular Fractures: A Systematic Review and Meta-Analysis.

Background and Objectives: Management of acetabular fractures is aimed at anatomically reducing and fixing all displaced or unstable fractures, as the accuracy of fracture reduction has been demonstrated to strongly correlate with clinical outcomes. However, there is a noticeable gap in the literature concerning the perioperative and postoperative care of patients with acetabular fractures, which ultimately can be potential risk factors for adverse outcomes and permanent disabilities. This study aimed to systematically review the available literature regarding rehabilitation practices, including weight-bearing protocols, across time points in surgically treated acetabular fracture patients and correlate these practices with functional outcomes. Methods: We systematically reviewed the Medline and PubMed databases and the Cochrane Central Register of Controlled Trials in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. The inclusion criteria were studies with adult patients (19+ years), publications from the last 10 years, articles focusing on rehabilitation or mentioning any aspect related to rehabilitation (such as weight-bearing or muscle training), and describing the surgical management of acute, isolated acetabulum fractures. Specific information was collected, including the fracture classification, time to surgery, surgical approach, surgical time, blood loss, fixation strategy, quality of reduction, postoperative rehabilitation protocol, complication rate, type(s) of complication, and outcome measurement(s). The choice(s) of surgical approach, surgical time, blood loss, and fixation strategy were stratified based on the fracture classification. The complication rate and type(s) of complication were calculated for all studies. Fractures were classified based on the Letournel classification. Results: A total of 494 articles were identified from the initial search, of which 22 (1025 patients) were included in the final review. The most common rehabilitation protocol favored isometric quadriceps and abductor strengthening exercises starting on the first postoperative day, with passive hip movement at 1-3 days postoperatively and active hip movement ranging from the first postoperative day to 4 weeks postoperatively. Partial weight-bearing with a walker or a pair of crutches was permitted from 1 to 12 weeks after surgery, and full weight-bearing was allowed depending on the patient's general condition and fracture healing state (generally at the end of 3 months). In only three studies did the patients start bearing weight in the early postoperative period (≤1 week). Meta-regression analysis was not performed due to the discrepancy between studies that reported a weight-bearing protocol ≤1 week and >1 week postoperatively. Conclusions: Our study suggests that an accelerated postoperative rehabilitation protocol, including early permissive weight-bearing, does not appear to increase the risk of loss of reduction or the rate of complications after surgical treatment of acetabular fractures. However, a proper meta-analysis was not possible, and the heterogeneity of the included studies did not allow us to conclude anything about the potential biomechanical and clinical benefits nor the negative effects related to this rehabilitation regimen in terms of functional results. There is an inconsistent use of PROMs for objectively calculating the effect size of the accelerated protocol compared with restricted weight-bearing regimes. We pose the need for higher-level evidence to proof our hypothesis.

Biomechanics of internal fixation in Hoffa fractures - A comparison of four different constructs.

OBJECTIVE: Compare the biomechanical effectiveness of four different bone-implant constructs in preventing fracture displacement under axial loading. METHODS: Twenty artificial femora had a standardized coronally oriented fracture of the lateral femoral condyle, representing a Hoffa fracture classified as a Letenneur type I. Four different fixation constructs were applied to the synthetic bones for biomechanical testing. The constructs consisted of a posterolateral (PL) buttressing locking plate in conjunction with two cannulated lag screws inserted from posterior to anterior (PA) - Group 1; Two cannulated screws inserted from anterior to posterior (AP) without plating- Group 2; A posterolateral (PL) buttressing locking plate in isolation - Group 3; and a combination of two lag screws from anterior to posterior (AP) in addition to a horizontal one-third tubular locking plate - Group 4. An axial load was applied to the fracture site with a constant displacement speed of 20 mm/min, and the test was interrupted when a secondary displacement was detected determining a fixation failure. We recorded the maximum applied force and the maximum fracture displacement values. RESULTS: Group 1 demonstrated the highest overall bone-implant axial stiffness with the lowest secondary displacement under loading. Groups 3 and 4 showed equivalent mechanical behavior. Group 2 presented the lowest mechanical stiffness to axial loading. The combination of the one-third tubular locking plate with anterior-to-posterior lag screws (Group 4) resulted in 302 % increase in fixation stiffness when compared to anterior-to-posterior lag screws only (Group 2). CONCLUSIONS: This study confirms the mechanical superiority of having a plate applied parallel to the main fracture plane in the setting of coronally oriented femoral condyle fractures. The addition of a horizontal plate, perpendicular to the main fracture plane, significantly increased the resistance to shearing forces at the fracture site when compared to constructs adopting just cannulated screws. LEVEL OF EVIDENCE: Biomechanical study.

LEADERSHIP DEVELOPMENT TRAINING FOR BRAZILIAN ORTHOPEDIC SURGEONS.

Objective: To report on the experience and impressions of the Brazilian orthopedic trauma surgeons attending the Leadership Development Program (LDP) hosted by the Sociedade Brasileira do Trauma Ortopédico (SBTO) in Sao Paulo, Brazil on November 4, 2022. Methods: Forty-eight orthopedic trauma surgeons from five different regions throughout Brazil were provided a link to complete The Big Five Test, a validated online personality assessment. The questionnaire was available in Portuguese and was intended to provide a background on individual personality traits and their influence on interpersonal interactions. The LDP integrated content from literature reviews specific to Latin America, established leadership programs from leading business schools, and various subject matter experts. Prior to the start of the LDP, participants received a pre-course survey evaluating demographic information, a needs assessment, and the prioritization of leadership topics utilizing a 5-point Likert-scale. Attendees participated in the one-day, interactive LDP focusing on the fundamental principles of leadership development, communication, personal development, emotional intelligence and negotiation. Following the LDP, a post-course evaluation was administered to determine the participants' overall experience, and suggestions for LDP improvement. Results: Forty-one of the forty-eight course participants completed the pre-course evaluation, whereas forty-six of the forty-eight participants completed the post-course evaluations. Overwhelmingly, the lack of opportunity was most prevalently reported as the main obstacle to attending a leadership course, as cited by 56% of respondents. Conclusion: Expanding the accessibility, diversity, and customizability of leadership programs can facilitate the development of personal tools needed to move healthcare forward. Critical topics include emotional intelligence and other differentiating leadership qualities that distinguish true transformational and servant leaders. Advancing leadership skills can stimulate networking, expose learners to experiential learning styles, inspire others to create positive change, and engender creative solutions for systematic improvements and health outcomes.

Antegrade posterior column screw fixation for acetabular fractures: It's time to standardize the surgical technique.

Antegrade fixation of posterior column fractures of the acetabulum is challenging due to the narrow corridor and risk of screw misplacement. Although both antegrade and retrograde lag screws have been previously described for posterior column fracture fixation, the literature lacks a standardized technique for correct and safe screw placement, especially in an antegrade fashion. This technical note aims to optimize intraoperative images during posterior screw insertion using the antegrade technique, according to predetermined landmarks to save surgical time, decrease radiation exposition, and prevent surgical complications.

Busch-Hoffa fracture: A systematic review.

BACKGROUND: Accomplish a thorough review on the existing biomechanical and clinical studies about coronal plane fractures of the distal femur. METHODS: We performed an electronic search of PubMed/MEDLINE database from April to June, 2023. The terms for the database search included "Hoffa fractures," OR "Busch-Hoffa fractures" OR "coronal plane fractures of the distal femur." RESULTS: The search identified 277 potentially eligible studies. After application of inclusion and exclusion criteria, 113 articles were analyzed in terms of the most important topics related to coronal plane fractures of the distal femur. CONCLUSION: Lateral coronal plane fractures of the distal femur are more frequent than medial, present a more vertical fracture line, and usually concentrate on the weight bearing zone of the condyle. The Letenneur system is the most used classification method for this fracture pattern. Posterior-to-anterior fixation using isolated lag screws (for osteochondral fragments-Letenneur type 2) or associated with a posterior buttressing plate (when the fracture pattern is amenable for plate fixation-Letenneur types 1 and 3) is biomechanically more efficient than anterior-to-posterior fixation. Anterior-to-posterior fixation using lag screws complemented or not by a plate remains a widely used treatment option due to the surgeons' familiarity with the anterior approaches and lower risk of iatrogenic neurovascular injuries. There is no consensus in the literature regarding diameter and number of screws for fixation of coronal plane fractures of the distal femur.

Antibiotic cement-coated plate is a viable and efficient technique for the definitive management of metaphyseal septic nonunions of the femur and tibia.

OBJECTIVE: the management of septic metaphyseal nonunions is challenging, with inconsistent outcomes. Antibiotic cement-coated implants have been demonstrated good outcome for diaphyseal infected nonunions, however there is no data in metaphyseal infected nonunions. METHODS: fifteen adult patients with septic metaphyseal nonunions of the femur or tibia were treated with antibiotic cement-coated plates. The antibiotic cement-coated plate was prepared with either gentamicin or vancomycin. Outcome measures were infection control, bone healing, return to pre-injury level on daily activities, and quality of life at the last follow-up visit. A p value of <5% was considered significant. RESULTS: Methicillin-susceptible S. aureus was isolated in 53.3% cases. Average postoperative follow-up time was 18 months. Local infection control and radiographic bone healing were adequately achieved in 93.3% patients. No patient presented recurrent symptoms of surgical site infection. Fourteen patients reported to be either able, or on the same level as before injury, with 73.3% reporting no problems in all five dimensions of the EQ-5D-3L. Persistent infection was the only variable associated with a reduced long-term quality of life. CONCLUSION: antibiotic cement-coated plate is a viable and efficient surgical technique for the definitive management of juxta-articular metaphyseal septic nonunions of the femur and tibia.
