Distal Radius Fracture in the Setting of Human Immunodeficiency Virus: Management and Adverse Events.

Previous research has highlighted the elevated fracture risk among patients with human immunodeficiency virus (HIV). The current study assesses the association between HIV and the management and adverse events of distal radius fractures. Patients with a distal radius fracture from 2016 to 2022 were identified in a national administrative database. Patients were stratified by HIV status, and antiretroviral therapy (ART) use was identified. Fracture treatment modality (open or closed) was determined, and adverse events were identified within 1 year of fracture. Treatment modality and adverse events were compared using logistic regression and chi-square tests, respectively. Among 396,544 patients with a distal radius fracture, 2,392 had HIV. HIV status was not associated with treatment modality. For patients with closed treatment, those with HIV had greater rates of malunion or nonunion and wrist arthritis. For patients with open treatment, HIV was also associated with greater incidence of malunion or nonunion. When stratifying by ART status, patients not on ART were less likely to undergo open treatment, whereas those with ART underwent open treatment at similar rates to HIV-negative patients. Compared with the HIV-negative cohort, those with HIV, and on ART were significantly more likely to sustain malunion or nonunion following closed treatment. Patients with HIV are at increased risk for fracture, and they are more likely to experience adverse events following both closed and open management of distal radius fractures. Surgeons should pay close attention to bone healing in patients with HIV, and future research should investigate the causes of these adverse events and assess their modifiable risk factors.

Clinical application of intramedullary nail fixation assisted by locking plates in segmental tibia fractures: A retrospective study.

It is unclear whether small plates are needed for augment fixation to provide a more stable mechanical environment in segmental fractures of the tibia treated with intramedullary nail. The purpose of this study was to investigate the efficacy of intramedullary nailing combined with locking plates in the treatment of segmental fractures of the tibia. This study included 41 patients with segmental tibia fractures between January 1, 2018 and January 1, 2023. Eighteen patients were treated with an intramedullary nail assisted by a locking plate (combination group), and 23 patients were treated with an intramedullary nail without a plate (nail group). The perioperative parameters of all patients were recorded, and clinical efficacy was evaluated during follow-up. The operation time was shorter but the incision was longer in the combination group (P < .05). The numbers of fluoroscopy procedures and the time to union were shorter in the combination group (P < .05). The rate of malunion in the nail group (4, 17.4%) was significantly greater than that in the combination group (0, 0%). At the last follow-up, no statistically significant differences in walking ability were detected. Our results suggest that a locking plate combined with an intramedullary nail for segmental tibial fractures may require a longer surgical incision, but it has significant advantages such as a shorter operative time and time to union, a shorter fluoroscopy time, and a lower rate of malunion and nonunion. Intramedullary nail fixation assisted by a locking plate is an effective method for treating segmental fractures of the tibia.

Minimally invasive treatment of talar neck fractures using the calcaneal distractor - a technical note

Talar neck fractures, though rare, pose significant challenges in treatment due to their complex nature and potential for severe complications. Despite the fact that most of talar fractures are treated operatively, there is scarcity of clear recommendations concerning appropriate surgical technique and care. Historically, conservative management was favored, but open reduction and internal fixation (ORIF) have become the standard of care. However, merely restoring rotation, axis, and length is insufficient; restoring the articulating surface in an anatomical manner is essential for long-term joint health. Surgical access to the fracture site via anteromedial and anterolateral approaches provides visualization, but risks compromising the sensitive, partly retrograde blood supply to the talar body. While being biomechanically superior, screws inserted from a posterior to anterior direction pose challenges in soft tissue preservation and accurate placement. Despite widespread usage of this technique, postoperative outcomes remain suboptimal with considerable rates of malunion, osteonecrosis and osteoarthritis. An overlooked technique in the literature is the use of a distractor, commonly employed in minimally-invasive surgical calcaneal fracture treatment in order to maintain length, alignment and joint reposition during fixation. With the potential to reduce soft tissue damage and preserve the blood supply minimally invasive techniques present a promising advancement in fracture management of talar neck fractures.

Bigger is not necessarily better - 2-ring circular frames associated with shorter duration of treatment in the management of complex tibial fractures - a retrospective cohort study.

Frame configuration for the management of complex tibial fractures is highly variable and is dependent upon both fracture pattern and surgeon preference. The optimal number of rings to use when designing a frame remains uncertain. Traditionally larger, multi-ring-per-segment constructs have been assumed to offer optimal stability and therefore favourable conditions for fracture healing but there is little in-vivo evidence for this and the recent concept of reverse dynamisation challenges this approach. We compared the clinical outcomes in 302 consecutive patients with tibial fractures treated in our unit with either a stable two-ring circular frame or a three-or-more-ring (3+) frame. The primary outcome measure was time spent in frame. Secondary outcomes were the incidence of malunion and the need for further surgical procedures to achieve bone union. The mean time in frame was 168 days for the 2-ring group and 202 days for the 3+ rings group (p = 0.003). No significant differences were found in the rate of malunion or the requirement for secondary surgical intervention to achieve union. The groups were evenly matched for age, co-morbidities, energy of injury mechanism, post-treatment alignment and presence of an open fracture. This study finds that 2-ring frame constructs are a reliable option associated with shorter duration of treatment and no increase in rates of adverse outcomes compared with larger, more complex frame configurations.

Outcomes of external versus internal fixation for traumatic lower limb fractures in low- and middle-income countries.

Lower limb fractures are common in low- and middle-income countries (LMICs) and represent a significant burden to the existing orthopaedic surgical infrastructure. In high income country (HIC) settings, internal fixation is the standard of care due to its superior outcomes. In LMICs, external fixation is often the surgical treatment of choice due to limited supplies, cost considerations, and its perceived lower complication rate. The aim of this systematic review protocol is identifying differences in rates of infection, nonunion, and malunion of extra-articular femoral and tibial shaft fractures in LMICs treated with either internal or external fixation. This systematic review protocol describes a broad search of multiple databases to identify eligible papers. Studies must be published after 2000, include at least five patients, patients must be aged > 16 years or treated as skeletally mature, and the paper must describe a fracture of interest and at least one of our primary outcomes of interest. We did not place restrictions on language or journal. All abstracts and full texts will be screened and extracted by two independent reviewers. Risk of bias and quality of evidence will be analyzed using standardized appraisal tools. A random-effects meta-analysis followed by a subgroup analysis will be performed, given the anticipated heterogeneity among studies, if sufficient data are available. The lack of easily accessible LMIC outcome data, combined with international clinical guidelines that are often developed by HIC surgeons for use in HIC environments, makes the clinical decision-making process infinitely more difficult for surgeons in LMICs. This protocol will guide research on surgical management, outcomes, and complications of lower limb shaft fractures in LMICs, and can help guide policy development for better surgical intervention delivery and improve global surgical care.

Functional Outcome and Patient Satisfaction After Primary vs Secondary Arthrodesis for Lisfranc Injuries: Toward a Single-Surgery Approach.

The choice between primary arthrodesis (PA) and open reduction and internal fixation (ORIF) for acute Lisfranc injuries remains contentious. Apart from primary treatment, arthrodesis is often used for treating chronic Lisfranc injuries, including patients in whom initial ORIF or nonoperative treatment failed. The aim of this study was to compare PA and secondary arthrodesis (SA) in terms of complications and functional outcome. A retrospective cohort study was conducted on trauma patients with Lisfranc injuries treated at a level 1 trauma center between July 1, 2010, and July 1, 2020. Selected patients were evaluated at the outpatient clinic and received a survey. Demographics, injury characteristics, management, complications, and patient-reported outcomes (American Orthopaedic Foot & Ankle Society midfoot score, Foot Function Index) were analyzed. Twenty-nine of 37 potential patients (78.4%; PA n = 11, SA n = 18) completed the survey with a median follow-up of 7.1 (PA) to 9.3 (SA) years (P = .01). The majority were female (n = 18, 62.1%); the mean age of PA patients was 57.1 years (SD 14.2) compared with 43.5 years (SD 17.1) in SA patients (P = .04). In the PA group, there was no infection, 100% union, and implants were removed in 5 of 11 patients. In the SA group, 11.1% (n = 2) developed infection, malunion rate was 11.1%, implants were removed in 33.3% (n = 6), and 22.2% required revision surgery. AOFAS was "good" in PA (77.7, SD 17.3) compared with rated "fair" in SA (67.1, SD 21.3, P = .19). FFI was better in PA (26.0, SD 26.2) than SA (37.6, SD 30.8, P = .32), which exceeded the minimally important clinical difference. Although this study was limited by sample size, the overall results suggest equivalent functional outcome, pain and treatment satisfaction in primary arthrodesis compared with secondary arthrodesis patients for treatment of Lisfranc injury.

Comparative analysis of two double-plate fixation techniques for intercondylar fractures of the distal humerus

This study was aimed to compare the clinical and radiographic outcomes of patients with intercondylar fractures of the humerus treated with orthogonal and parallel plating methods via precontoured plates. This was a retrospective comparative study conducted on 50 adult patients with intercondylar humerus fractures that were surgically treated over an eleven-year period. The patients were divided into two groups: Group A underwent internal fixation via parallel plating, whereas Group B received orthogonal plating. Clinical outcomes were evaluated via the Mayo Elbow Performance Score (MEPS), and the radiographic assessments included time to consolidation, pseudoarthrosis, malunion and hardware removal. Both groups presented similar demographic and preoperative characteristics. The functional outcomes assessed by the MEPS were not significantly different between the groups. Radiographically, comparable healing times and rates of complications, including pseudoarthrosis, malunion and hardware removal, were observed. The study findings suggest that both orthogonal and parallel plating methods yield comparable clinical and radiographic outcomes in the treatment of intercondylar humerus fractures. These results underscore the effectiveness of both techniques and emphasize the importance of further research to elucidate the optimal plating method for specific fracture patterns.

Tibial Plafond Fractures Type C: Open Reduction and Internal Fixation versus External Fixation by Ilizarov: (A Systematic Review)

Abstract Background Tibial Plafond Fractures affect weight-bearing articular surface and comprise &amp;lt; 1% of all lower extremity fractures. Such fractures are due to rotational or axial-loading forces as a result of high-energy trauma. Plafond means ceiling or dome. The Talus has tibial plafond as a dome or ceiling and articulates with the distal tibia with its smooth surface. Rotational force may produce spiral fractures; it may be extra-articular or intra-articular. Usually, rotational forces produce less soft tissue injuries whereas axial compressive forces produce intra-articular fractures with more soft tissue injuries. Aim of the Work to compare open reduction internal fixation (ORIF) and external fixation by Ilizarov in patients with pilon fracture type C and to clarify which method is better in terms of reduction and union results and major complications. Patients and Methods After ethical committee approval, this Systematic review was conducted on Patients aged with 18 years or older with tibial plafond fractures of type C according to the AO/OTA classification including Studies and published papers between January 2000 and January 2022. This systematic review was conducted on human subjects in different literatures collected from different medical websites between January 2000 and January 2022 in which we involved clinical and/or functional outcomes in ORIF versus Ilizarov fixation for operative treatment of tibial plafond fracture type C according to the AO/OTA classification with follow up period of at least 6 months. Five Studies literature (Four retrospective and one Prospective) that involved 250 patients, fulfilled the study criteria and were included in this study. Results As regards the time till surgery and healing, the current systematic review revealed that there was statistically significant increase in the time till surgery (days) in ORIF group (11.75 ± 2.67) versus EF group (6.95 ± 3.14) (p-value &amp;lt;0.001) and non-significant increase in the time to union (days) in ORIF group (48.10 ± 44.11) than EF group (41.73 ± 37.53) (p-value = 0.287). The current study results revealed that the Range of Ankle Motion showed a statistically significant increase in the mean dorsiflexion and plantarflexion in ORIF group than EF group (p- value &amp;lt;0.001). As regards complications, Analysis of the complications (nonunion, malunion, superficial, deep infections, Osteomyelitis and Arthritis) revealed a statistically significant increase in the percentage of patients with complications in EF group compared to ORIF group (p value &amp;lt;0.001) with significant difference in rates of malunion (p = 0.034) and superficial infection (p = 0.012) between ORIF and EF for treatment of TPF. Although the risk of deep infection was higher in the EF group, it was not found to be statistically significant (p = 0.811). Conclusion this study provides an overview of functional outcome and complications after common surgical strategies for management of tibial plafond fractures. Both ORIF and CEF are acceptable treatment options for management of TPF; however, functional levels vary substantially. External fixation results in the higher rate complications of malunion, superficial infection and decreased range of motion compared to Open reduction and internal fixation, while Open reduction and internal fixation was associated with significant bad functional outcome and delayed time to healing and surgery. Post-traumatic arthritis deep infection and non-union rates were comparable in both groups. The results reported here can aid patients and their surgeons in the decision for operative treatment.

A Retrospective Case Series of Single-Screw vs Dual-Screw Fixation for Treatment of Medial Malleolus Fractures.

Medial malleolus fractures (MMFs) are common across the world. Currently, there is a lack of consensus on the number of screws used in fixation of MMF. Our aim was to compare the radiographic outcomes of MMF with patients between fractures that have either undergone single-screw (SS) or dual-screw (DS) fixation. This retrospective study assessed patients who had undergone fixation of their MMF from 2012 to 2022. Analysis of their perioperative radiographs was performed to determine the initial type of injury and then radiographic outcomes of nonunion and malunion. A total of 653 patients suffering bimalleolar fractures were identified across a 10-year period. There were 271 patients (41.50%) in the SS group and 382 in the DS group (58.50%). There was no difference found in the nonunion rate of SS (19.19% [52 of 271]) compared with DS (18.85% [72 of 382]) (P = .931). A statistically significant difference between malunion rates was found between the SS group (11.07% [30 of 271]) compared with the DS group (3.93% [15 of 382]) (P < .001).On multiregression analysis, factors that gained significance for development of nonunion was nonfixation of syndesmosis (P = .039), ankle dislocation on arrival (P < .001), and nonrestoration of fibular length (P < .001). Other factors that showed significance for failure to achieve medial anatomical reduction was nonfixation of syndesmosis (P < .001). Use of an SS rather than DS showed a significant increase in nonanatomical reduction but did not increase nonunion or reoperation rate. Syndesmosis fixation was associated with higher rates of MMF nonunion and malunion; as such, surgeons should have a low index of suspicion of injury and fixation. Level III, retrospective case series.

Outcome Comparison of Multidirectional Locked Nailing and Plating for Distal Tibial Fractures: A Comparative Analytical Study

Introduction: This comparative analytical study explores the functional outcomes of treating distal tibial fractures using multidirectional locked nailing and plating. Distal tibia fractures, resulting from high-energy trauma, pose challenges due to soft tissue damage, infection risks, and potential unfavorable outcomes. Our study seeks to evaluate and contrast the functional results of treating distal tibial fractures using multidirectional locked nailing versus plating techniques. Materials and Methods: Conducted at Saveetha Medical College and Hospital from August 2022 to October 2023, the study involved 20 cases meeting specific criteria. Adult patients (18-70 years) with closed fractures and grade I compound fractures of distal tibia (AO type 43-A1, 43-A2, and 43-A3) were included. The cases were evenly divided between multidirectional locked nailing and plating groups. Subsequent evaluations, comprising both radiographic and clinical analyses, were performed at 6, 12, and 24-week intervals. Results: The study encompassed various parameters, including age distribution, causes of fractures, weight-bearing protocols, and joint movements. Multidirectional locked nailing demonstrated a shorter fracture union time, promoting earlier weight-bearing and functional exercises. Ankle and knee scores in this group indicated successful joint function restoration but with a higher malunion rate. Plating exhibited a lower malunion rate but a prolonged time to union. Complications, including superficial infections and wound dehiscence, were observed, emphasizing the importance of postoperative monitoring. Despite challenges, the plate group achieved satisfactory functional outcomes, highlighting fair to good ankle scores and full knee movement in all cases. Conclusion: In conclusion, the study underscores the distinctive advantages and considerations of each treatment approach. Multidirectional locked nailing facilitates faster union and joint function restoration but carries a higher malunion risk. Plating, with a lower malunion rate, requires meticulous postoperative care. The choice between the two methods should be individualized, considering patient-specific factors, fracture characteristics, and the surgeon's expertise. This research contributes valuable insights for informed decision-making in distal tibia fracture treatment.

A MORPHOLOGICAL REVIEW OF MEDIAL MALLEOLAR FRACTURES: ARE THERE ANY FACTORS WHICH MAY PREDISPOSE TO NONUNION AND MALUNION?

BackgroundMany approaches to management of medial malleolar fractures are described in the literature however, their morphology is under investigated. The aim of this study was to analyse the morphology of medial malleolar fractures to identify any association with medial malleolar fracture non-union or malunion.MethodsPatients who had undergone surgical fixation of their MMF were identified from 2012 to 2022, using electronic patient records in a single centre. Analysis of their preoperative, intraoperative, and postoperative radiographs was performed to determine their morphology and prevalence of non-union and malunion. Lauge-Hansen classification was used to characterise ankle fracture morphology and Herscovici classification to characterise MMF morphology.ResultsA total of 650 patients were identified across a 10-year period which could be included in the study. The overall non-union rate for our cohort was 18.77% (122/650). The overall malunion rate was 6.92% (45/650). There was no significant difference in union rates across the Herscovici classification groups. Herscovici type A fractures were significantly more frequently malreduced at time of surgery as compared to other fracture types (p=.003). Medial wall blowout combined with Hercovici type B fractures showed a significant increase in malunion rate. There is a higher rate of bone union in patients who have been anatomically reduced.ConclusionThe morphology of medial malleolar fractures does have an impact of the radiological outcome following surgical management. Medial wall blowout fractures were most prevalent in adduction-type injuries; however, it should not be ruled out in rotational injuries with medial wall blowouts combined with and Herscovici type B fractures showing a significant increase in malunions. Herscovici type A fractures had significantly higher malreductions however the clinical implications of mal reducing small avulsions is unknown.

ELDERLY ANKLE FRACTURE MANAGEMENT: PUTTING THE EVIDENCE INTO PRACTICE

IntroductionFollowing publication of the Ankle Injury Management (AIM) trial in 2016 which compared the management of ankle fractures with open reduction and internal fixation (ORIF) versus closed contact casting (CCC), we looked at how the results of this study have been adopted into practice in a trauma unit in the United Kingdom.MethodsInstitutional approval granted to identify eligible patients from a trauma database. 143 patients over 60 years with an unstable ankle fracture between 2017 and 2019 (1 year following publication of the AIM trial) were included. Open fractures, and patients with insulin-dependent diabetes or peripheral vessel disease were excluded (as per AIM criteria). Radiographs were reviewed for malunion and non-union. Clinical notes were reviewed for adverse events. Minimum follow up was 24 months.ResultsOf the 143 patients, 42 patients (29.4%) received a moulded cast with a return to theatre rate of 21.4%, malunion rate of 30.1%, and infection or wound problem rate of 4.8%. When the exact phrase “close contact cast” was specified in 21 patients (14.7%), there was a 19.0% return to theatre rate, 28.6% malunion rate, and a 4.8% infection or wound problem rate. 101 patients (70.6%) had ORIF with a return to theatre rate of 10.9%, malunion rate of 5.0%, and infection or wound problem rate of 13.9%.DiscussionOur results show a high rate of complication with cast management of unstable ankle fractures in this older population. This was improved where CCC was specified, but remains higher even than those published in the AIM trial. Whilst there is certainly a role for CCC in carefully selected patients, we would advise caution in the widespread adoption of a close contact casting technique.

Evaluating Fibular Intramedullary Nails vs Traditional Plating in Geriatric Ankle Fractures: A 12-Year Single-Center Retrospective Study.

This study evaluates the outcomes of fibular intramedullary nails (IMNs) compared to traditional plates and screws (PS) in the surgical treatment of unstable ankle injuries in patients aged ≥65 years. We conducted a retrospective study involving 32 elderly patients with unstable ankle fractures treated with IMNs from 2010 to 2022. A comparison was made with 125 case-control patients treated with PS during the same period. Outcomes compared included postoperative wound and nonwound complications, surgical reduction, union rates, implant removal rates, and the Olerud Molander Ankle Score (OMAS) at a minimum follow-up of 2 years. The IMN group had a higher incidence of high-energy injuries, open fractures, concomitant surgery, and perioperative transfusion requirements than the PS group. Additionally, the IMN group developed fewer wound-related (3.1% vs 20% in the PS group, P = .043) and non-wound-related complications (18.8% vs 39.2% in the PS group, P = .030). Both groups had similar initial weightbearing restrictions, fracture union times, mean OMAS scores, rates of malunion or nonunion, and delayed implant removal times. Notably, there were significant differences in the quality and adequacy of mortise alignment between the groups (good: 53.1% in IMN group vs 79.2% in PS group, fair: 46.9% in IMN group vs 20.8% in PS group, P = .006). Although the IMN group had an inferior outcome in the quality and adequacy of mortise reduction compared with the PS group, elderly patients with ankle fractures treated with IMN showed comparable functional outcomes to those treated with PS but with lower complication rates. Future research in this area will provide vital information for developing optimal treatment strategies, thereby improving the overall care of elderly patients with ankle fractures.

Screw versus Kirschner wire fixation for lateral humeral condyle fractures in children:a meta analysis

To compare screw versus Kirschner wire fixation in the treatment of lateral humeral condyle fractures in children. A systematic search was conducted in PubMed, Embase, the Cochrane library, Web of Science, China National Knowledge Internet(CNKI), Wanfang Datebase from in ception to February 2022. Studies comparing screws and Kirschner wire fixation in the treatment of lateral humeral condyle fractures in children were included. Outcome measures included and excluded by a set of inclusion and exclusion criteria and evaluated for their quality, their excellent and good rate of fracture healing, malunion, delayed union or nonunion, infection, limitation of elbow flexion or extension(>10°) were extracted and analyzed using software Rev Man 5.3. A total of 9 retrospective studies involving 647 patients were included, with 255 patients in the screw fixation group(including screw combined with Kirschner wire) and 392 patients in the Kirschner wire fixation group. Meta analysis showed the following:infection rate in the screw group was significantly lower than that in the Kirschner wire group[OR=0.22, 95%CI(0.09, 0.56), P=0.001]. There were no significant differences between the 2 groups in excellent and good rate of fracture healing, malunion rate(P>0.05). Subgroup analysis showed that infection rate in the screw-only group was significantly lower than that in the Kirschner wire group[OR=0.18, 95%CI(0.05, 0.65), P=0.009]. For lateral humeral condyle fractures, Screw fixation alone had a lower infection rate than kirschner wire fixation and screw combined with Kirschner wire fixation. There were no significant differences in the excellent and good rate of fracture healing, malunion. In terms of postoperative efficacy and safety of internal fixation, orthopaedic surgeons are more likely to recommend screws for fixation of lateral humeral condyle fractures in children.

THE BIGGER, THE BETTER? TWO-RING CIRCULAR FRAMES AND DURATION OF TREATMENT IN THE MANAGEMENT OF TIBIAL FRACTURES: A RETROSPECTIVE COHORT STUDY

IntroductionFrame configuration for the management of complex tibial fractures is highly variable and is dependent not only on fracture pattern and soft tissue condition but also surgeon preference. The optimal number of rings to use when designing a frame remains uncertain. Traditionally, larger, stiffer constructs with multiple rings per segment were thought to offer optimal conditions for bone healing, however, the concept of reverse dynamisation questions this approach.Materials &amp; MethodsWe compared clinical outcomes in 302 consecutive patients with tibial fractures treated in our unit with either a two-ring circular frame or a three-or-more-ring (3+) frame. The primary outcome measure was time spent in frame. Secondary outcomes were the incidence of malunion and the need for further surgical procedures to achieve bone union. The groups were evenly matched for age, co-morbidities, energy of injury mechanism, fracture classification, post-treatment alignment and presence of an open fracture.ResultsThe mean time in frame was 168 days for the 2-ring group and 200 days for the 3+ rings group (p=0.003). No significant difference was found in the rate of malunion (p=0.428) or the requirement for secondary surgical intervention to achieve union (p=0.363). No significant difference in time in frame was found between individual surgeons.ConclusionsThis study finds that 2-ring frame constructs are a reliable option associated with significantly shorter duration of treatment and no increase in rates of adverse outcomes compared with larger, more complex frame configurations. Although this study cannot identify the underlying cause of the difference in treatment time between frame designs, it is possible that differences in mechanical stability lead to a more favourable strain environment for fracture healing in the 2-ring group.

Comparison of two versus three-screw fixation for biplanar chevron medial malleolar osteotomy.

This study was designed to compare the clinical outcomes and complications of using two versus three screws to fix the biplanar chevron medial malleolar osteotomy (MMO). A retrospective review was conducted on 43 patients (46 ankles) who underwent biplanar chevron MMO to treat talus osteochondral lesions. Of these, MMO was fixed with two parallel screws placed perpendicular to the osteotomy plane in 16 ankles, while in the remaining 30 ankles, MMO was secured with two parallel screws plus an additional third screw inserted parallel to the tibial plafond. Patients were divided into two groups based on the fixation method and clinical outcomes, union and malunion rates, and complications were compared. Demographic and clinical characteristics such as age (p: 0.411), gender distribution (p: 0.119), affected side (p: 0.126), lesion grades (p: 0.056), and lesion sizes (p: 0.310), immobilization (p: 0.119) and weight-bearing periods (p: 0.252) were statistically similar across both groups. Initial malreduction were observed in five cases within the three-screw group and one case in the two-screw group (p: 0.307). However, neither group exhibited any progressive step-off or gap in the follow-up radiographs, and osteotomy union was achieved in all patients. Delayed union was observed in one patient from the three-screw group. Significant improvements in American Orthopedic Foot and Ankle Society scores were observed in both groups, with no functional discrepancies evident at the final follow-up (p: 0.488). The study found no significant differences in union rates, complications, or clinical outcomes between two and three-screw fixation methods for medial malleolar osteotomies (MMO). Both methods allowed for effective MMO fixation without loss or displacement post-surgery, suggesting their safety and efficacy. Level III, retrospective comparison.

Principles of Minimally Invasive Reduction and Nail Fixation for Subtrochanteric Femur Fractures.

Subtrochanteric femur fractures have a reputation as difficult orthopaedic injuries to treat. Strong deforming forces, including the hip musculature and high physiologic forces, must be counteracted to obtain and maintain reduction. Adding to the complexity is a wide variety of fracture morphologies that must be recognized to execute an appropriate surgical plan. The challenging nature of this injury is demonstrated by nonunion rates of 4% to 5%, but some series have reports of up to 15% and malunion rates of 10% to 15%. Improved outcomes have been shown to be dependent on appropriate reduction and stable fixation, which can be achieved with less surgical insult. The treating surgeon must have a thorough understanding of the injury characteristics and reduction techniques to appropriately execute minimally invasive techniques for these difficult fractures.

Association of Smokeless Tobacco and Complications Following Ankle and Hindfoot Arthrodesis.

The purpose of this study was to (1) evaluate the rates of postoperative complications following ankle or hindfoot arthrodesis among current smokeless tobacco users and people who smoke compared to matched controls, and (2) compare rates of postoperative complications in current smokeless tobacco users vs people who smoke tobacco cigarettes. A retrospective cohort study was conducted using a large national database. For patients who underwent ankle or hindfoot arthrodesis, smokeless tobacco users (n = 131) and people who smoke (n = 1948) were matched 1:4 with controls, and smokeless tobacco users (n = 131) were matched 1:4 with people who smoke tobacco cigarettes (n = 524). Orthopaedic complications within 90 days, 1 year, and 2 years were compared using multivariable logistic regressions. Within 90 days of ankle or hindfoot arthrodesis, smokeless tobacco users demonstrated significantly higher rates of hardware removal (odds ratio [OR] 5.01, 95% CI 1.65-15.20), wound disruption or dehiscence (OR 3.00, 95% CI 1.21-7.44), and pooled complications (16.0% vs 5.9%, OR 2.84, 95% CI 1.50-5.38) compared with tobacco-naïve controls. The rates of hardware removal, wound disruption and dehiscence, and pooled complications remained significant in the smokeless tobacco cohort at 1 and 2 years. At 2 years following ankle or hindfoot arthrodesis, smokeless tobacco users additionally demonstrated significantly higher rates of infection (OR 6.08, 95% CI 1.15-32.05) and nonunion (OR 2.35, 95% CI 1.31-4.20) compared with tobacco-naïve controls. Within 90 days of ankle or hindfoot arthrodesis, smokeless tobacco users demonstrated significantly lower rates of malunion or nonunion than patients who smoke tobacco cigarettes (OR 0.34, 95% CI 0.12-0.97), whereas all other complications were not significantly different. Smokeless tobacco use is associated with higher rates of complications following ankle or hindfoot arthrodesis compared with tobacco-naïve controls, and physicians should screen for smokeless tobacco use specifically and encourage cessation before operating electively. Level III, retrospective cohort study.

A morphological review of medial malleolar fractures – A large single centre series

BackgroundMany approaches to management of medial malleolar fractures are described in the literature however, their morphology is under investigated. The aim of this study was to analyse the morphology of medial malleolar fractures to identify any association with medial malleolar fracture non-union or malunion. MethodsPatients who had undergone surgical fixation of their MMF were identified from 2012 to 2022, using electronic patient records. Retrospective analysis of their preoperative, intraoperative, and postoperative radiographs was performed to determine their morphology and prevalence of non-union and malunion. Lauge-Hansen classification was used to characterise ankle fracture morphology and Herscovici classification to characterise MMF morphology. ResultsA total of 650 patients were identified across a 10-year period which could be included in the study. The overall non-union rate for our cohort was 18.77% (122/650). The overall malunion rate was 6.92% (45/650). Herscovici type A fractures were significantly more frequently mal-reduced at time of surgery as compared to other fracture types (p = .003). Medial wall blowout combined with Hercovici type B fractures showed a significant increase in malunion rate. There is a higher rate of bone union in patients who had been anatomically reduced. ConclusionThe morphology of medial malleolar fractures does have an impact of the radiological outcome following surgical management. Medial wall blowout fractures were most prevalent in adduction-type injuries; however, it should not be ruled out in rotational injuries with medial wall blowouts combined with and Herscovici type B fractures showing a significant increase in malunions. Herscovici type A fractures had significantly higher malreductions. Level of evidenceLevel 3 – Retrospective Cohort Study

A novel construct for Lapidus bunionectomy utilizing nitinol staples

The Lapidus bunionectomy is a popular procedure that allows for powerful hallux valgus correction through arthrodesis of the first metatarsal-cuneiform joint. Although widely used since its advent in the 1930s, controversy still exists surrounding what the most superior fixation construct is for this procedure. Commonly used fixation constructs include, but are not limited to, crossed screws, plate and screws, and monorail external fixators. Nitinol staples, although relatively new to the internal fixation world, offer unique advantages that other forms of internal fixation do not. These advantages include easy insertion, dynamic compression, and superelasticity which may impact rates of bunion recurrence, nonunion, and malunion, all of which are of concern with this procedure. This study details a unique surgical technique for the Lapidus bunionectomy utilizing a 2-leg staple dorsally and a 4-leg staple medially in a 90 degree construct. We propose that use of a 4-leg staple medially may mimic the advantages of plantar plating without the difficulty of positioning and obtaining adequate anatomic exposure.
