Use of antibiotic-cement coated plate in the treatment of Gustilo-Anderson type III long bone fractures in low- and middle-income countries vs external fixation: A multicentre randomized control trial study protocol

BackgroundOne of the great challenges in the management of open fractures is postoperative infection with a higher incidence in Gustilo-Anderson type III fractures. Definitive management of such fractures in developing countries is usually with external fixators with its attendant complications such as deep fracture-related infection, non-union, and consequent increased re-operation rates. Recently, there has been a novel method of using antibiotic-cement coated implants such as intramedullary nails and locking plates in the treatment of infected non-unions with reported excellent outcomes. This protocol aims to describe the hypothesis, objectives, design and statistical analysis of a randomized control trial that compares the infection rate between the use of antibiotics-cement coated plate and external fixation in the management of Gustilo-Anderson type III long bone fractures. MethodsThis is a multicentre, open-label, parallel group, superiority, randomized, control trial. All patients with type III long bone fractures who present at the emergency department will be screened for enrolment and only those patients that meet the inclusion criteria will be registered for the study. Patients will be randomized using a centralized 24-hr computerized randomization system into two groups: antibiotic-cement coated plate group and the external fixation group. The primary outcome will be occurrence of infection at any time during the course of one year follow-up which will be counted once for each of the patients. The secondary outcomes are union rate, re-operation rate and change in Health Related Quality of Life (HRQoL) from baseline to end of follow-up. Analysis will be done using R (R Core Team, 2023) and Rstudio (Rstudio Team, 2023). DiscussionLiterature has shown that use of antibiotic-coated plate in the management of severe open long bone fractures is effective in reducing infection rate. A significant difference in infection rate with use of antibiotic-cement coated plate compared to use of external fixator for open fractures will be a welcome intervention in developing countries.

Preliminary results of stabilization of far distal tibia fractures with the distal tibial nail: A prospective, multicenter case series study

IntroductionThe distal tibial nail (DTN) is a novel retrograde intramedullary nail used for distal tibial fracture stabilization. We investigated the clinical results of DTN use for distal tibial fractures and compared them with those reported in the literature on locking plates and antegrade intramedullary nails. Materials and methodsThis multicenter, prospective, observational cohort study examined distal tibial fractures with AO/OTA classification 43 types: A1, A2, A3 or C1. The primary outcomes included bone union rate, soft tissue problems, and surgical complications. Secondary outcomes were EuroQol-5 Dimension-5 Level (EQ-5D-5L), Self-Administered Foot Evaluation Questionnaire (SAFE-Q), and American Orthopaedic Foot and Ankle Society (AOFAS) hindfoot clinical scores 1 year postoperatively. Incidence of varus or valgus/anterior-posterior flexion deformity with a difference of ≥5° and postoperative reduction loss rate were evaluated. ResultsFive men and five women were enrolled (mean age, 69 years [range, 30–77 years]), including one open-fracture-type Gustilo type IIIB case. Bone union was observed in all patients at 6 months postoperatively. Delayed union, leg edema, and guide pin breakage were observed in three, one, and one cases, respectively. No soft tissue or surgical complications were observed. During the final follow-up, the EQ-5D-5L, SAFE-Q, and AOFAS hindfoot scores were 0.876 (0.665–1.0), 83–92, and AOFAS 92.6 (76–100), respectively. Varus and retroflexion deformities were observed in one case each. DiscussionDTN has been reported to have biomechanically equivalent or stronger fixation strength than locking plates or antegrade intramedullary nails. In addition, while DTN was thought to be less invasive for soft tissue and can avoid injury to the knee, it was thought that care should be taken to avoid medial malleolus fractures and posterior tibialis tendon injuries. Comparisons with literature treatment results for locking plates and antegrade intramedullary nails showed comparable to advantageous results. ConclusionsDTN treatment results for distal tibial fractures were as good as those for locking plates and antegrade intramedullary nails. DTN is useful for stabilization and does not compromise the surrounding soft tissues.

MEDIUM- AND LONG-TERM OUTCOMES OF SURGICAL RECONSTRUCTION IN ACUTE CHARCOT NEUROARTHROPATHY

IntroductionCharcot neuroarthropathy (CN) of foot and ankle presents significant challenges to the orthopaedic foot and ankle surgeon. Current treatment focuses on conservative management during the acute CN phase with offloading followed by deformity correction during the chronic phase. However, the deformity can progress in some feet despite optimal offloading resulting ulceration, infection, and limb loss. Our aim was to assess outcomes of primary surgical management with early reconstruction.MethodsBetween December 2011 and December 2019, 25 patients underwent operative intervention at our specialist diabetic foot unit for CN with progressive deformity and or instability despite advanced offloading. All had peripheral neuropathy, and the majority due to diabetes. Twenty-six feet were operated on in total - 14 during Eichenholtz stage 1 and 12 during stage 2. Fourteen of these were performed as single stage procedures, whereas 12 as two-stage reconstructions. These included isolated hindfoot reconstructions in seven, midfoot in four and combined in 14 feet. Mean age at the time of operation was 54. Preoperative ulceration was evident in 14 patients.ResultsMean follow up was 45 months (Range 12–98). There was 100% limb salvage. One-year ambulation outcomes demonstrate FWB in bespoke footwear for 17 patients and in an ankle foot orthosis (AFO), Charcot restraint orthopaedic walker (CROW) or bivalve cast for seven. All preoperative ulceration had healed. Union was achieved in 18/21 hindfoot reconstructions and 7/18 midfoot reconstructions. There were nine episodes of return to theatre, of which five were within the first 12 months. There was one episode of new ulceration.ConclusionSurgical management of acute CN (Eichenholtz one and two) of the foot provides functional limb salvage. In particular, hindfoot reconstruction shows good rates of bony union. It should be considered in ‘foot at risk’ presentations of acute CN foot.

The clinical efficacy of Medial Sustain Nail(MSN) and Proximal femoral nail anti-rotation(PFNA) for fixation of medial comminuted trochanteric fractures: a prospective randomized controlled trial.

To evaluate the clinical efficacy of the Medial Sustain Nail (MSN) for medial comminuted trochanteric fractures fixation in comparison to Proximal Femoral Nail Antirotation (PFNA) through a clinical study. A non-inferiority randomized controlled trial was conducted at a single centre between July 2019 and July 2020. Fifty patients diagnosed comminuted trochanteric fractures were randomly assigned to either the MSN group (n = 25) or the PFNA group (n = 25). A total of forty-three patients were included in the final study analysis. The primary outcome measure was Short Form 36 health surgery physical component summary (SF-36 PCS) score. Secondary outcomes included the Oxford Hip Scores (OHS), weight bearing, complication relate to implant and so on. This study was not blined to surgeons, but to patients and data analysts. The MSN demonstrated significantly better functional outcomes as measured by SF-36 PCS and OHS at sixmonths postoperative compared to PFNA (p < 0.05). Union of fractures in the MSN group reached 90.9% at threemonths after surgery, whereas the PFNA group achieved a union rate of 57.1% (p < 0.05). Furthermore, weight-bearing time of MSN group was earlier than PFNA group (p < 0.05). Additionally, complications related to implant usage were more prevalent in the PFNA group (33.3%) compared to the MSN group (4.5%) (p < 0.05). MSN exhibited superior quality of life outcomes compared to PFNA at sixmonths postoperative. This indicates that MSN effectively reconstructs medial femoral support in patients with comminuted trochanteric fractures, which facilitates early weight-bearing and accelerates the recovery process.

Superior versus anteroinferior plating for mid-shaft clavicle fractures: a randomized clinical trial.

Clavicle fractures represent 2.5-4% of all fractures observed in emergency services. 80% occurs in the middle third. Treatment by plating requires a higher level of evidence. To compare the functional outcomes of mid-shaft clavicle fractures managed with superior plating compared to anteroinferior plating. A randomized, double-blind, parallel, superiority clinical trial. Patients with fractures of the clavicles AO15B1 and AO15B2 were studied. Patients were randomized to be treated with either 3.5 mm superior or anteroinferior plating. A rehabilitation program was designed for both groups. The primary outcome measure was the Disability of Arm, Shoulder, and Hand (DASH) score; secondary outcomes included pain, union rate, and complication rates. Twenty-eight patients were studied and were eligible for analysis. Significant differences were found in the function assessed with the DASH score at 30 days for the superior plating compared with anteroinferior (43.74 vs. 29.26, respectively, p = 0.027), 60 days (23.97 vs. 11.18, p = 0.021), and 90 days (9.52 vs. 3.5, p = 0.016). One loosening with superficial infection was found with superior plating. Using an anteroinferior reconstruction plate in diaphyseal fractures offers better functional results than the upper plate in patients with fractures of the middle third of the clavicle.

OUTCOMES OF SINGLE VERSUS COMBINATION FIXATION IN DISTAL FEMUR FRACTURES: A CHRISTCHURCH EXPERIENCE

IntroductionDistal femur fractures have traditionally been stabilized with either lateral locking plate or retrograde intramedullary nail. Dual-plates and nail-plate combination fixation have the theoretical biomechanical advantage, faster union and allows patients to weight bear immediately.The aim of this study is to compare single vs combination fixation, and evaluate outcomes and complications.MethodWe retrospectively reviewed all patients over 60, admitted to Christchurch Hospital, between 1st Jan 2016 and 31st Dec 2022, with an AO 33A/33B/33C distal femur fracture. Patient demographics, fracture characteristics, operation details, and follow up data were recorded.Primary outcomes are union rate, ambulatory status at discharge, and surgical complications. Secondary outcomes include quality of reduction, operation time and rate of blood transfusions.Results114 patients were included. (92 single fixation, 22 combination fixation).Baseline demographic data and fracture characteristics did not differ between the cohorts.There was no difference in the rate of union or time to union between the two cohorts. Combination fixation patients were allowed to weight-bear as tolerated significantly more than single fixation patients (50% vs 18.9%, p=0.003). There was no difference in length of hospital stay, transfusion, complication and mortality rates.Medial translation of the distal articular block was significantly lower in the combination fixation cohort (1.2% vs 3.4%, p=0.021). Operation time was significantly longer in the combination fixation cohort (183mins vs 134mins, p&lt;0.001).DiscussionThe results show no difference in achieving union or time to union, despite better quality of fracture reduction with dual fixation. This differs to previously published literature. The clear benefit of combination fixation is immediate weight-bearing. As expected, operation times were longer with combination fixation, however this did not translate to more complications.ConclusionCombination fixation allows earlier weight bearing, at the cost of longer operation times.

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.

Modified double-pulley fixation provides better reduction of bone fragments and union compared to single-point fixation in bony Bankart lesions.

The purpose of this study was to compare clinical scores and imaging outcomes of bony Bankart lesions that underwent single-point and modified double-pulley fixation after at least 2 years of follow-up. Patients who underwent surgery to treat bony Bankart injuries were included and divided into groups A and B. A total of 69 patients were included (32 in group A and 37 in group B). Patients in group A underwent arthroscopic modified double-pulley fixation and patients in group B underwent arthroscopic single-point fixation. Three-dimensional computed tomography (3D-CT) was used to assess glenoid reduction one day after surgery. Postoperative bony union was assessed using 3D-CT and multiplanar reconstruction images 6 months after surgery. Constant-Murley, Rowe rating system, visual analogue scale and University of California at Los Angeles and American Shoulder and Elbow Surgeons scores were recorded before and after surgery. In terms of imaging measurements, there was no significant group difference in the preoperative size of the glenoid defect, the size of the bony fragment or the expected postoperative size of the glenoid defect. The sizes of the actual postoperative glenoid defects differed significantly between the groups (p = 0.027), as did the absolute difference between the expected and actual glenoid defect sizes (p < 0.001). At 6 months postoperatively, 50.0% of group A patients and 24.3% of group B patients exhibited complete bony union (p = 0.027); the rates of partial union were 37.5% and 56.8%, respectively. At the final follow-up, all clinical scores were significantly better than the preoperative scores (all p < 0.05), with no significant group differences (not significant). The use of the modified double-pulley technique with two anchors to treat bony Bankart injuries provides a better reduction of bone fragments than single-point fixation with two anchors and was associated with a higher rate of early bone union. Level III.

A novel MO-YOLOv4 for segmentation of multi-class bridge damages

Most studies of multi-class damage segmentation overlook two prominent and critical challenges: the substantial variations in damage scale and the susceptibility of network training to background interferences. As a consequence, achieving the desired performance in multi-class damage segmentation becomes a difficult task. To tackle these challenges, a novel multi-class damage segmentation method, MO-YOLOv4, is proposed based on the widely used YOLOv4 structure. MO-YOLOv4 incorporates the Multi-Scale Attention (MSA) module to greatly enhance the feature extraction ability for multi-class damages, and employs the Oriented Bounding Box (OBB)-based segmentation strategy for effectively reducing the influence of background interferences during the network training phase. The effectiveness of the MSA module and OBB-based segmentation strategy is validated through verification and ablation experiments. In the comparative study, the Mean Precision rate (MP), Mean Recall rate (MR), Mean F1-score (MF) and Mean Intersection over Union rate (MIoU) of the proposed MO-YOLOv4 reach up to 82.49%, 72.73%, 77.04% and 64.28%, respectively, indicating the superior level of segmentation performance offered by MO-YOLOv4 in comparison to the mainstream semantic segmentation methods for multi-class damages.

ISOLATED ANKLE FUSION FOR FAILED TOTAL ANKLE ARTHROPLASTY USING A SPINE CAGE AND ANTERIOR PLATING CONSTRUCT

BackgroundTotal ankle replacements (TARs) are becoming increasingly more common in the treatment of end stage ankle arthritis. As a consequence, more patients are presenting with the complex situation of the failing TAR. The aim of this study was to present our case series of isolated ankle fusions post failed TAR using a spinal cage construct and anterior plating technique.MethodsA retrospective review of prospectively collected data was performed for 6 patients that had isolated ankle fusions performed for failed TAR. These were performed by a single surgeon (IW) between March 2012 and October 2014. The procedure was performed using a Spinal Cage construct and grafting in the joint defect and anterior plating. Our primary outcome measure was clinical and radiographic union at 1 year. Union was defined as clinical union and no evidence of radiographic hardware loosening or persistent joint lucent line at 1 year.ResultsThe mean follow-up was 37.3 months (SD 13.2). Union was achieved in 5 of the 6 patients (83%). One patient had a non-union that required revision fusion incorporating the talonavicular joint that successfully went on to unite across both joints. Another patient had radiographic features of non-union but was clinically united and asymptomatic and one required revision surgery for a bulky symptomatic lateral malleolus with fused ankle joint.ConclusionThe failing TAR presents a complex clinical situation. After removal of the implant there is often a large defect which if compressed leads to a leg length discrepancy and if filled with augment can increase the risk of non-union. Multiple methods have been described for revision, with many advocating fusion of both the ankle joint and subtalar joint. We present our case series using a spinal cage and anterior plating that allows preservation of the subtalar joint and a high rate of union.

ARTHROSCOPIC ARTHRODESIS OF THE ISOLATED TALONAVICULAR JOINT

BackgroundWhereas arthroscopic arthrodesis of the ankle is commonplace and of the subtalar joint is established, reports of arthroscopic talo-navicular fusion are a rarity.AimTo review a case series to establish if arthroscopic talo-navicular arthrodesis is a feasible surgical option.MethodsArthroscopic decortication of the talo-navicular joint is performed via x1-2 sinus tarsi portals and x1-2 accessory talo-navicular portals using a standard arthroscope and a 4.5 barrel burr. Internal fixation is by a 5mm screw from the navicular tuberosity and x2 headless compression screws introduced under image intensification from the dorsal navicular to the talar head. Between 2004 and 2017 a consecutive series of 164 patients underwent arthroscopic hindfoot arthrodeses of which 72 involved the talo-navicular joint. Only 13 procedures were of that joint alone in unsullied feet. The medical records of these 13 patients were reviewed to assess radiological fusion, complications and improvement of pre-operative state.ResultsAll Talo-navicular joints were successfully decorticated. All united radiologically by a mean 4.4 months (range 3–8). There were no major complications. All patients reported improvement to their pre-operative symptoms but one patient developed lateral column pain requiring fusion.ConclusionsArthroscopic Talo-navicular arthrodesis is technically feasible with good rates of union. Complications were rare, making the technique attractive when encountering a poor soft tissue envelope. The surgery cannot be used if bone grafting is required. Long term discomfort can arise from adjacent joints. Accurate alignment is critical.

Comprehensive comparison between conservative therapy and surgical management for completely displaced and comminuted mid-shaft clavicle fractures

PurposeIt is still controversial whether complete displaced mid-shaft clavicle fractures should be treated with internal fixation or conservative therapy. This retrospective study aims to compare clinical outcomes of two treatment protocols.Materials and methods105 patients with displaced and comminuted mid-shaft clavicle fractures were included in this study, among which 55 patients were treated conservatively and 50 patients accepted surgical fixation and were followed up for over 20 months on average. Rate of union, malunion, time taken for union, functional outcome, self-reported satisfaction and complications were compared.ResultsUnion rate of operative group (n=49, 98.0%) was higher than the non-operative group (n=48, 87.3%). Time taken for union in operative group (2.37±1.06 months) was shorter than the non-operative group (3.69±1.01 months). Malunion and asymmetric were only seen in the conservative group. Numbness of the shoulder was only reported in the operative group (n=23, 46.0%). Most of patients in the operative group (n=45, 90%) accepted a second operation to remove the implant. No statistically difference was found in self-reported satisfaction, Quick-DASH and Constant-Murley score. The operative group returned to work faster (1.47±0.89 to 3.34±1.37 months), regained full range of motion earlier (1.66±0.78 to 3.83±1.24 months) and regained strength faster (3.86±2.45 to 8.03±2.78 months) than the non-operative group.ConclusionComplete displaced and comminuted mid-shaft clavicle fractures treated surgically have more reliable union and faster recovery when compared to conservatively treated fractures.

First Metatarsophalangeal Joint Arthrodesis With Complete Resection of the Subchondral Bone Plate

First metatarsophalangeal arthrodesis is associated with high union rates but there is a wide range of union incidence reported. Whether the subchondral plate is completely resected, is not reported by individual studies and without meticulous care, there is often residual subchondral plate. The primary aim was to report our union rate following first metatarsophalangeal arthrodesis with complete resection of the subchondral plate, locking plate fixation and immediate protected weight bearing. A retrospective case study of 2 surgeons was performed from August 2016 to June 2023. Our study was unique in that all patients had complete resection of the subchondral plate to trabecular bone. One hundred seventeen feet were identified for analysis, in 112 patients following exclusion criteria. Patients were excluded if they had less than 3 months follow-up, revisional surgery or charcot. Demographic data and indications for the procedure were reported. A single construct locking plate with an interfragmentary compression screw through the plate was used in 37 feet and a locking plate with separate interfragmentary compression screw was used in 80 feet. We reported a nonunion incidence of 0.9% (n = 1) with a delayed union incidence of 0.9% (n = 1) and a broken hardware incidence of 0.9% (n = 1). Complete resection of subchondral plate with early weight bearing and locking plate fixation had a high union rate for first metatarsophalangeal arthrodesis. Our results compare favorably with union rates in the literature, where there is often residual subchondral plate.

Tibiotalocalcaneal ankle arthrodesis with posterior approach arthroscopic-assisted hindfoot nailing.

End-stage ankle arthrosis causes severe pain and limited movement. Tibiotalocalcaneal arthrodesis with arthroscopy-assisted hindfoot nailing can be used to achieve a high union rate and low complication rate. We aimed to examine the early- and mid-term results of patients treated with this technique from various perspectives and to evaluate them by comparing them with the current literature. Data were collected from 25 patients who met the established criteria and underwent TTCA with arthroscopic-assisted hindfoot nailing. In addition to the demographic data of the patients, their clinical and pain scores were evaluated using the American Orthopedic Foot and Ankle Society (AOFAS) and visual analogue scale (VAS). Additionally, the union time and complication data during the follow-up period were examined. When the AOFAS and VAS scores of the 25 patients were examined, a significant improvement was observed in the preoperative period and early postoperative period comparisons (p < .001). No significant change was observed between the comparison of the postoperative 12th month and last postoperative control clinical scores. While the union rate of the patients was observed to be 92%, the average union time was 13.1 ± 3.5weeks. During follow-up, peri-implant fracture, deep infection, and non-union were observed in one patient each (12%). The early- and mid-term postoperative results of patients treated with TTCA surgery with posterior approach arthroscopic-assisted hindfoot nailing show that this technique may be an option with low complication and high union rates for the appropriate group of patients planned for ankle arthrodesis.

Radiographic and functional results of Ilizarov fixation in the management of nonunion of tibia and femur fractures: a retrospective case series.

Femoral and tibial fractures may result in delayed union and nonunion, posing significant challenges in orthopedic practice. The Ilizarov technique has emerged as a promising solution for managing these complex cases. Evaluate the radiographic and functional results of Ilizarov fixation in the treatment of nonunion of tibia and femur fractures. Retrospective. Hospitals affiliated with a university hospital. Patient demographics, fracture characteristics, and treatment details were analyzed for the period from October 2015 to September 2022 in patients who were treated for nonunion of the tibia and femur using the Ilizarov fixator. Clinical and radiological assessments were performed using the Association for the Study and Application of Methods of Ilizarov (ASAMI) criteria. The study focused on assessing the average duration for union and frame removal, bone results, successful union rates, and functional results using the ASAMI criteria, obtaining data from the existing medical records, spanning various medical facilities treating nonunion fractures. 126 patients. The average duration for union and frame removal was 8 months, with excellent bone results observed in 60.32% of cases. Out of 126 patients, 118 achieved successful union, while there were 2 failure cases necessitating amputation (1.52%). Functional results revealed excellent outcomes in 39.68% of cases. Complications included pin tract infections, ankle and knee stiffness, and limb shortening. External fixation duration and infection eradication were consistent with previous research, emphasizing the technique's effectiveness. The Ilizarov technique proved highly effective in managing nonunion tibia and femur fractures, offering favorable outcomes in terms of union, infection control, pain relief, and functional recovery. While excellent bone outcomes do not guarantee optimal function, this method remains a reliable approach for complex cases. Potential biases inherent in retrospective analyses and the need for further randomized controlled trials to comprehensively compare treatment modalities.

Functional Outcome of Solid Interlocking Nail in Open Tibial Fracture at a Tertiary Care Center: A Descriptive Cross-sectional Study.

There is a high incidence of open fractures accounting 23% of all tibial fractures. The minimal soft tissue and precarious blood supply of the shaft of tibia make these fractures vulnerable to complications. The treatment should be decided through thoughtful analysis for personality of injuries and the status of the soft tissue. Intramedullary nailing allows stable fixation with minimal soft tissues dissection and preserve the soft tissue and allows early joint motion with higher rate of union. The purpose of our study was to find the outcome of open tibial fractures lower than Gustilo type IIIb, that were treated by unreamed solid interlocking intramedullary nails. A descriptive cross-ectional study was conducted from December 2021 to June 2023 after taking approval from ethical committee. All 34 patients treated with solid interlocking intramedullary nail, without reaming for open tibial fracture during 18 months period were included in the study. Final follow up was done at one year and the outcome was assessed by Modified Ketenjian's criteria. The mean time of union rate was 15.82±3.95 weeks. Complications were: superficial infections in 4 (11.76%) patients and deep infection in 1 (2.94%) patient. Using Modified Ketenjian's Criteria, 26 (76.47%) patients had an excellent result followed by good in 7 (20.59%), fair in 1 (2.94%) and there was no case with poor outcome. Solid intramedullary interlocking nail is an effective treatment with minimal soft tissue dissection for open tibia fracture less than GA III B as it provides stable fixation with early mobilization and provides a high rate of union, less complication and early return to function.

Enhancing Techniques for Adaptable Decision Feedback Balancer for 5G Communication

Abstract: This complete review examines two basic parts of cutting edge correspondence frameworks. First and foremost, it investigates novel plan procedures and models for Adaptable Decision Feedback Balancer (ADFB) in rapid correspondence frameworks. Strategies like look-into tables, disseminated math, and prescient equal branch slicers are utilized to upgrade union rates, throughput, and mistake execution while limiting equipment intricacy. The proposed plans exhibit significant advancement in region, power proficiency, and rationale usage across different regulation plans, channel models, and portability situations. Furthermore, the examination digs into Super Dependable Low Idleness Correspondence (SDLIC) headways inside the 5G New Radio (NR) downlink, tending to actual layer difficulties determined in 3GPP Delivery 15. The review presents a clever correspondence framework utilizing super codes to moderate between image impedance in remote conditions. Also, inventive equal plans for high velocity Choice Input Adjusters (CIAs) and equipment proficient models for versatile balancers utilizing disseminated number-crunching are introduced. The joined discoveries contribute significant bits of knowledge into streamlining versatile balancers for group of people yet to come correspondence frameworks and progressing SDLIC in 5G NR.

Arthroscopic Talonavicular Arthrodesis for the Management of Talonavicular Osteoarthritis

The talonavicular joint is a common site for osteoarthritis of the foot. Talonavicular arthrodesis is the surgical treatment for symptomatic talonavicular osteoarthritis. Classically, this is performed via an open approach and is associated with a rate of nonunion that ranges from 3% to 37%. Arthroscopic talonavicular arthrodesis has been proposed to provide better intra-articular visualization, conserve bone blood supply to improve the union rate, and reduce soft-tissue complications such as wound dehiscence, infection, and neurovascular injury. The purpose of this Technical Note is to describe the details of arthroscopic talonavicular arthrodesis for management of talonavicular osteoarthritis.

Outcome of Early Retrograde Closed Intramedullary Fixation of Fracture Shaft of Femur by Titanium Elastic Nail in Children

Background: Paediatric femoral shaft fractures are common in orthopaedic practice and can be managed using various modalities, each with its advantages and disadvantages. The Titanium Elastic Nailing System has emerged as a promising treatment option, offering potential advantages over traditional methods. Objective: This study aimed to evaluate the functional and radiological outcomes and operative complications of paediatric femoral shaft fractures treated with the Titanium Elastic Nailing System. Methods: A prospective interventional study was conducted from July 2020 to July 2021. Thirty children aged 6-14 years (mean age 11.32 ±3.76) were selected using purposive sampling and strict inclusion/exclusion criteria. Patients were followed up for at least 24 weeks at four-week intervals, and outcomes were assessed using Flynn's TEN scoring criteria. Results: All 30 patients completed the study. Radiological union was achieved in 80.0% of cases within 7-10 weeks, with 90.0% of patients able to bear full weight by the 12th week. Minor complications occurred in 20.0% of cases, while no major complications were reported. 80.0% of cases had excellent outcomes, 20.0% were satisfactory, and no poor outcomes were observed. Conclusion: The Titanium Elastic Nailing System is an excellent method for treating paediatric femoral shaft fractures, demonstrating high rates of radiological union and functional recovery with a low incidence of complications.

Circular frame versus reamed intramedullary tibial nail in the treatment of grade III open tibial diaphyseal fractures.

Grade III open tibial diaphyseal fractures are challenging to treat and controversy exists on whether to treat them with an intramedullary nail (IMN) or a circular frame (CF). This study aims to compare outcomes for intramedullary nail and circular frame in the treatment of open tibial diaphyseal fractures. Retrospective study at a major trauma center of all patients admitted with a grade III open tibial diaphyseal fracture between January 2016 and January 2022. The primary outcome measures were major complications: non-union, malunion, refracture, DBI and amputation. Secondary outcome measures were time to union and reoperation rates. Fifty-five patients were included in the study, 32 patients in CF group and 23 patients in IMN group. There were no significant differences in the baseline demographics of patients in both groups. Major complications were recorded in 13 limbs (54%) in IMN group and in 18 limbs (56%) in CF group which were not statistically significant (p = 0.797). Deep bone infection rates were noted in 4 (12.5%) in the CF group, compared to 1 (4%) in IMN group; however, the result was not statistically significant (p = 0.240). Amputation rates as a result of infected non-unions were seen in 1 limb (4%) in IMN group and 2 limbs (6%) in CF group (p = 0.99). Median time to union was significantly shorter in IMN group at 30weeks compared to 30weeks for CF group (p = 0.04). IMN should be the treatment of choice in the treatment of grade III open tibial diaphyseal fracture, but CF should be considered for delayed treatment and in patients with bone loss.
