Open Reduction Of Fractures Research Articles

How good is good enough? Lessons learned from review of outcomes of 50 patients following extraoral open reduction and internal fixation of condylar neck and base fractures at a regional major trauma centre

The management of mandibular fractures is routine owing to their frequency, particularly those of the mandibular condyle, which are invariably common. Notwithstanding disparities in the literature, the international consensus towards which fractures of the mandibular condyle benefit from open surgical intervention is almost universally accepted. Closed reduction or non-operative management may be utilised in certain circumstances. Whilst outcome research has addressed complications with respect to operative side effects, outcomes related to the quality of bone repair and the setting in which this is delivered have not been universally addressed. The aim of this study was to determine the predictability of translating an indicated operative treatment plan into an acceptable functional result. We evaluated the outcomes of 59 extracapsular condylar fractures in 50 patients who were treated by extraoral open reduction and internal fixation (ORIF) between March 2021 and August 2022. We reviewed demographic data, surgical approach, and plating strategy, and critically evaluated the clinical and radiological outcomes. Whilst we found that the quality of reduction was not universally perfect, the majority were within tolerance, which we set according to the Strasbourg Osteosynthesis Research Group (SORG) definition for minimal displacement (<2 mm overlap and 10° angulation). The cohort had good functional occlusion and minimal long-term postoperative complications. Two patients required re-operation for non-union, and we discuss causality in these cases. In conclusion, we found that ORIF of condylar neck and base fractures is predictable in real-time surgical practice with respect to functional outcome. However, if imperfectly reduced, there is a small risk of non-union.

Cannabis Abuse Is Associated With Greater Medical Complications, Emergency Department Visits, and Readmissions Following Open Reduction and Internal Fixation for Distal Radius Fractures.

Despite increased legalization, little is known about the influence of cannabis use disorder (CUD) following open reduction and internal fixation (ORIF) for distal radius fractures (DRFs). The aims were to determine whether CUD patients undergoing ORIF for DRF have increased: (1) medical complications; and (2) health care utilization (emergency department [ED] visits and readmission rates). Patients were identified from an insurance database from 2010 to 2020 using Current Procedural Terminology codes: 25607, 25608, and 25609. Patients with a history of CUD were 1:5 ratio matched to controls by age, sex, tobacco use, alcohol abuse, opioid dependence, and comorbidities. This yielded 13,405 patients with (n = 2,297) and without (n = 11,108) CUD. Outcomes were to compare 90-day medical complications, ED visits, and readmissions. Multivariable logistic regression models computed the odds ratios of CUD on dependent variables. P values less than .005 were significant. The incidence of CUD among patients aged 20 to 69 years undergoing ORIF increased from 4.0% to 8.0% from 2010 to 2020 (P < .001). Cannabis use disorder patients incurred significantly higher rates and odds of developing 90-day medical complications (15.24% vs 5.76%), including pneumoniae (3.66% vs 1.67%), cerebrovascular accidents (1.04% vs 0.32%), pulmonary emboli (0.57% vs 0.16%), respiratory failures (1.00% vs 0.48%), and surgical site infections (1.70% vs 1.04%; all P < .004). Emergency department visits (2.53% vs 1.14%) and readmission rates (5.79% vs 4.29%) within 90 days were higher among cannabis abusers. With a greater number of states legalizing cannabis, hand surgeons should be cognizant of the association with increased 90-day complications and health care utilization parameters.

Risk factors for surgical site infections following open reduction and internal fixation in patients with tibial plateau fractures.

This retrospective cohort study aimed to identify the risk factors associated with postoperative wound infections in patients undergoing open reduction and internal fixation for tibial plateau fractures. The study was conducted between January 2019 and December 2022, with stringent inclusion and exclusion criteria. Data were collected from the Electronic Health Record system, including demographic information, lifestyle habits, comorbid conditions and surgical variables like preoperative American Society of Anesthesiologists (ASA) scores. The IBM Statistical Package for the Social Sciences, version 27.0, was utilized for rigorous statistical analyses. Univariate analysis identified several factors, such as body mass index (BMI), smoking status and diabetes mellitus, as significant predictors of postoperative wound infection. Multivariate logistic regression revealed that BMI, type of fracture (open vs. closed), surgery duration exceeding 150 min, preoperative albumin levels below 35 g/L and preoperative ASA score of 3 or higher were significant independent risk factors (p < 0.05). Patients with open fractures, preoperative malnutrition, elevated preoperative ASA scores and a history of smoking are at a heightened risk of developing postoperative wound infections. Timely preoperative evaluation of these risk factors is crucial for minimizing the risk of surgical site infections and optimizing clinical management.

Is the Direct Fixation of Displaced Quadrilateral Plates in Acetabular Fractures Necessary?

Quadrilateral plate fractures represent a heterogeneous group of acetabular fractures. Accurate reduction is required to prevent post-traumatic arthritis. The purpose of this study is to determine the reduction effect of the direct fixation of quadrilateral plates in acetabular fractures, and to evaluate the strength of direct fixation compared to indirect fixation. Between 2005 and 2021, 49 patients underwent surgery for open reduction and internal fixation in acetabular fractures with severely displaced quadrilateral plates. Twenty-nine patients comprised the indirect fixation group, and twenty patients comprised the direct fixation group. In a comparison of primary outcome between two groups, 10 out of 29 indirect-group patients and 1 out of 20 direct-group patients developed post-traumatic osteoarthritis, wherein the difference between the two groups is statistically significant. In the assessment of postoperative Matta's radiological reduction status, 19 out of 20 patients in the direct group had achieved anatomical and congruent reduction. The treatment using a direct reduction and internal fixation improved the reduction quality of articular displacement and offered a better survivorship of the affected hip joint.

A comparison between ilioinguinal and modified Stoppa approach in anterior column acetabular fractures

IntroductionPelvis fractures are among the most difficult fractures to manage and treat for Orthopedic surgeons. Anatomic reduction is the main goal to reach in the acetabular fractures’ treatment. The following study compares clinical outcomes and complications of Ilioinguinal versus modified Stoppa approach in Open Reduction and Internal Fixation (ORIF) of anterior column acetabulum fractures. Materials and methodsA comparative analysis on 90 patients undergoing ORIF on acetabular fracture has been performed. Patients have been divided into two groups. The first group was treated by Ilioinguinal approach (n = 48), the second group by modified Stoppa approach (n = 42). The following parameters have been compareted: quality of fragment reduction; operative time; peri‑ and post-operative blood loss; complications; clinical and radiographic outcomes. ResultsThe modified Stoppa approach has shown a shorter mean operative time (146 min vs 175 min), fewer complications (14/48 vs 6/42), less blood loss both in the perio-operative phase (0.8 Hb pt vs 1.3 Hb pt) than in postoperative one (1.1 Hb pt vs 1.5 Hb pt), a lower rate of nerve, infections and critical complications. On the other hand, the ilioinguinal approach has showed better results in terms of quality of fracture reduction (43/48 patiens with anatomical or near anatomical reduction vs. 37/42). No significant differences concerning vascular lesions, clinical and functional outcomes have been found between the two groups. ConclusionsThe modified Stoppa approach results in shorter operative time, less intra-operative blood loss and fewer complications than the ilioinguinal one. Greater anatomic reduction is achieved by Ilioinguinal approach; however, this does not necessarily translate into better clinical and functional outcomes which, overall, are comparable in the two analysed approaches. In conclusion, the modified Stoppa approach is deemed to be a better alternative in treating these fractures.

Distractor Application and Dry Arthroscopy to Improve Articular Visualization During Scapula Fracture Surgery Via a Posterior Approach.

Intra-articular glenoid displacement is an indication for open reduction and internal fixation of scapular fractures. However, direct visualization of the glenoid is limited, and articular reductions are typically performed and assessed using extra-articular cortical reduction reads and fluoroscopic imaging. In this technique, we describe the application of a distractor for direct visualization of the glenoid articular surface. In this way, anatomic reduction of the glenoid articular surface can be assessed and achieved. In addition, we discuss the use of a portable, dry arthroscopy when needed. This technique has resulted in good-to-excellent articular reductions by adjusting extra-articular reads that seemed adequate before intra-articular visualization. This technique is safe, requires minimal extra set-up or instruments, and results in good-to-excellent articular reductions.

Unicortical versus bicortical plate fixation for midshaft clavicular fractures

BackgroundThe aim of this study was to compare the functional and radiological outcomes of unicortical vs bicortical fixation in patients with midshaft clavicular fractures who were treated using pre-contoured locking plates. MethodsWe performed a prospective multicenter study of 45 individuals who underwent open reduction and internal fixation of midshaft clavicular fractures with precontoured locking plates between March 2017 and December 2019. Twenty-five patients were treated with bicortical screws and 20 patients with unicortical screws. Functional outcomes were assessed at 6 months and 12 months after surgery using the Constant score, the 11-item version of the Disabilities of Arm, Shoulder and Hand (Quick- DASH) score and the Single Assessment Numeric Evaluation (SANE) score. Pain was evaluated using a visual analog scale (VAS). The rate of return to work and sports was also recorded. Radiologic evaluation was obtained in the immediate postoperative day, monthly until fracture consolidation, at 6 months and 12 months. All intraoperative and postoperative complications were documented. ResultsAt both 6 and 12 months, the follow-up rates were 100%, and the mean age was 28.5 years (range, 20 to 45 years). The mean postoperative Constant score, Quick DASH, and SANE score at 12 months were 93.5 (±6), 2.3 (±3), and 92% (±7), respectively. There were no significant differences in the functional scores between the groups neither at 6 months nor at 12 months. Of the 30 active workers, 97% were able to return to their previous working routine and from the 25 patients who practiced sports before the injury,92% returned to sports all at the same level. All the fractures healed in both groups. There were 6 complications (13%). ConclusionIn young, active patients with displaced midshaft clavicular fractures, both unicortical and bicortical locked plates achieved 100% bone consolidation, with excellent functional outcomes and a low rate of complications without significant differences between the groups. Therefore, locked plates with unicortical fixation could be a very good alternative for the management of young patients with midshaft clavicular fractures, potentially avoiding severe neurovascular complications.

Precise minimally invasive treatment of mandibular fracture in children assisted by digital surgery technology

Objective: To explore the role of digital three-dimensional printing technology and multifunctional board in the treatment of mandibular fracture in children. Methods: From January 2006 to January 2022, 42 children with mandibular fracture were treated by Department of Stomatology, in The First Affiliated Hospital of Bengbu Medical College, including 25 males and 17 females. The patients, aged from 4 to 12 years, with the median age was 10 years old, were divided into observation group (22 cases) and routine group (20 cases) according to the treatment methods. In the observation group, the multifunctional board was made before operation, and the CT data of the children were imported into Mimics software in".dicom"format, and the displaced mandible was virtually reset. The jaw reduction model was made by three-dimensional printing, and the surgical operation was simulated on the reduction model to determine the model and position of the internal fixation device and shape it. During the operation, the fracture was reduced and fixed according to the preoperative design; The conventional group was treated with open reduction and internal fixation of mandibular fracture by traditional methods, and the clinical application value was compared and analyzed through the intraoperative situation, occlusal relationship, and follow-up of the two groups. Results: The total intraoperative bleeding volume [(30.25±4.02) ml] and surgical time [(64.3±9.2) min] in the observation group were significantly lower than those in the conventional group [(35.13±5.69) ml and (84.6±13.9) min, respectively] (F=6.18, P=0.003; F=1.32, P=0.001). The excellent and good rate of occlusal relationship in the observation group [96% (21/22)] was significantly higher than that in the conventional group [85% (17/20)] (F=4.27, P=0.039). The incidence of complications, the observation group, 1 case of poor occlusion, 1 case of postoperative infection; In the routine group, there were 3 cases with poor occlusion, 1 case with nerve injury, 1 case with root injury and 1 case with tooth germ injury. Conclusions: The application of digitization three-dimensional printing technology combined with multifunctional occlusal plate in children's mandibular fracture is minimally invasive, safe, efficient and accurate, and the clinical effect is good.

Fixation of Mallet Fractures Using a Modified Hook Plate Technique: A Prospective Case Series of 17 Patients.

Objective Various modalities have been suggested to manage mallet fractures; however, inappropriate treatment can lead to extension lag, a swan neck deformity, or arthritis of the distal interphalangeal joint (DIPJ). The current study aimed to evaluate the results (functional, radiological, and complications) of open reduction and internal fixation (ORIF) of mallet fractures using low-cost hook plates fabricated from low-profile titanium mini plates. Methods A prospective case series of 17 consecutive patients (average age of 32.3 years) with mallet fractures (six were Wehbe Type IB and 11 were Wehbe Type IIB). Eleven (64.7%) were males. The affected hand was dominant in all patients, and the affected digit was the index in 6 (35.3%), the ring in 5 (29.4%), the small in 3 (17.65%), and the middle in 3 (17.65%) patients. The same fellowship-trained hand surgeon performed all surgeries. Results The average operative time was 37.65 minutes. After an average follow-up of 10.94 months (range 6-27), the average DIPJ motion was 50° ° (range 20°-70°), the extensor lag was noted in 4 (23.5%) patients, and complications were reported in 6 (35.29%) patients. According to Crawford criteria, 6 (35.3%) patients achieved excellent results, 7 (41.2%) achieved good results, and 4 (23.5%) achieved fair results. Conclusion The modified hook plate technique for fixation of mallet fractures is a beneficial, economical, yet demanding technique that adequately provides stable fixation to allow early DIPJ motion with acceptable functional outcomes.

Surgical Management of Swan Neck Deformity Following Mallet Finger Injury: A Review of 25 Patients Over 20 Years.

Swan neck deformity develops as a sequela of chronic mallet finger. Surgical management can include soft tissue reconstruction or distal interphalangeal joint (DIPJ) fusion. Studies examining the incidence and management of posttraumatic swan neck deformity following mallet fracture are limited. A retrospective, single-institution review of patients undergoing surgical management of swan neck deformity following a traumatic mallet finger from 2000 to 2021 was performed. Patients with preexisting rheumatoid arthritis were excluded. Injury, preoperative clinical, and surgical characteristics were recorded along with postoperative outcomes and complications. Twenty-five patients were identified who had surgical intervention for swan neck deformity. Sixty-four percent of mallet fingers were chronic. Median time to development of mallet finger was 2 months. Twelve (48%) mallet fingers were Doyle class I, 6 (24%) were class III, and 7 (28%) were class IVB. Forty percent of injuries failed nonoperative splinting trials. Sixteen (64%) underwent primary DIPJ arthrodesis, 8 (32%) underwent DIPJ pinning, and 1 underwent open reduction and internal fixation of mallet fracture. The complication rate was 50% overall, and 33% of surgeries experienced major complications. The overall reoperation rate was 33%. Proximal interphalangeal joint hyperextension improved by 11° on average. Median follow-up was 61.2 months. The development of symptomatic swan neck deformity following traumatic mallet finger injury is rare. All patients warrant an attempt at nonsurgical management. Attempts at surgical correction had a high rate of complications, and DIPJ fusion appeared to provide the most reliable solution.

Open reduction and internal fixation of irreducible displaced femoral neck fracture with femoral Neck System: a preliminary study

BackgroundMost displaced femoral neck fractures can achieve satisfactory anatomical reduction by closed reduction, but there are still some that cannot reset satisfactorily after closed reduction, and open reduction are required. Such fractures that cannot be repositioned successfully by closed reduction are called irreducible displaced femoral neck fractures in this study. The objective of our study was to evaluate the efficacy of direct anterior incision with the Femoral Neck System in the treatment of irreducible displaced femoral fractures.MethodsA total of 16 young and middle-aged patients with irreducible displaced femoral neck fractures involving Garden type III and IV were treated using Femoral Neck System fixation by open reduction through Direct Anterior Approach between January 2020 to September 2021. Functional outcomes and postoperative complications were assessed during follow-up. Clinical outcomes were evaluated by the Hip Harris score. The postoperative reduction was evaluated by the Garden Index. Observe postoperative complications.ResultsAll patients were followed up with a mean follow-up time of 21.1(12–30) months, and according to radiological results, all patients achieved fracture healing, with a mean healing time of 4.25 months. All 16 patients received grade Garden I and II reductions, and there was no significant difference in the anteroposterior Garden reduction index between the first day after surgery (166.13 ± 5.61) and the 12th month after surgery(164.94 ± 4.49) (P>0.05) and no significant difference in lateral Garden index between the first day after surgery(171.06 ± 4.46) and the 12th month after surgery(169.38 ± 3.98) (P<0.05). According to the Hip Harris score scale, 13 patients received excellent and 3 patients received good. The postoperative Hip Harris Score(17.19 ± 4.8) was significantly higher than the preoperative score(92.19 ± 3.4), and the difference was statistically significant (P < 0.05). No or mild femoral neck shortness occurred in 12 (75%) patients, moderate shortening occurred in 3 (18.75%) patients, and severe shortening occurred in 1 (6.25%) patient. None of the patients experienced femoral head necrosis, fracture nonunion, or incision infection. One patient developed deep venous thrombosis of the lower extremity.ConclusionsThe Direct Anterior Approach combined with Femoral Neck System is an excellent treatment for irreducible displaced femoral neck fracture and achieved good functional outcomes and anatomical reduction with low complications.

Non-Surgical Site-Related Complications in Mandibular Fracture Surgery – A Problem of Elderly Patients?

Scientific evidence of nonsurgical site-related complications in mandibular fracture patients is limited. The purpose was to measure the frequency of nonsurgical site complications in patients with mandible fractures, describe the types of complications, and identify the risk factors associated with these complications. A retrospective cohort study was conducted at the Helsinki University hospital between 2018 and 2021. Patients undergoing surgery with open reduction and internal fixation of mandibular fracture(s) were evaluated. Patients under 16years of age were excluded. Primary predictor variable was age. Patient-related predictor variables were sex, long-term disease(s), smoking, and alcohol and/or drug abuse. Injury and fracture-related variables were injury mechanism, type and site of facture, combined craniofacial fracture(s), and associated injury(s). The primary outcome variable was nonsurgical site-related postoperative complication. The secondary outcome variable was type of complication. Not applicable. The main outcome variable was cross tabulated for pairwise comparisons with predictor variables. Multivariate logistic regression was performed for statistically significant (P<.05) variables. The data included 314 patients (age range: 16 to 89years; mean age: 38years old; median age: 33years old); most (78.3%) were men. Nonsurgical site-related postoperative complications occurred in 6.7% of patients. The most common complication type was pulmonary complication (36.0%), followed by urinary complication (20.0%) and general infection (16.0%). Nonsurgical site-related postoperative complications were most likely to occur in patients who were elderly (adjusted odds ratio [aOR] 5.55; 95% CI 1.92 to 16.21; P=.002), had combined craniofacial fractures (aOR 2.92; 95% CI 1.06 to 8.03; P=.038), and abused alcohol or drugs (aOR 4.51; 95% CI 1.70 to 11.96; P=.003). Pulmonary complications occurred more often in elderly patients, whereas urinary complications were more common in younger patients. The types of nonsurgical site complications in mandibular fracture patients increase and vary according to the patient's age. Awareness of possible complications related to different age groups helps anticipate and identify these in clinical work, and to consider the overall treatment of the patient beyond the fracture.

Effect of operative time in outcomes following surgical fixation of hip fractures: a multivariable regression analysis of 35,710 patients.

Prolonged operative time is a risk factor for increased morbidity and mortality after open reduction and internal fixation (ORIF) of hip fractures. However, the quantitative nature of such association, including graduated risk levels, has yet to be described. This study outlines the graduated associations between operative time and (1) healthcare utilisation, and (2) 30-day complications after ORIF of hip fractures. The National Surgical Quality Improvement Program (NSQIP) database was queried (January 2016-December 2019) for all patients who underwent ORIF of hip fractures (n = 35,710). Demographics, operative time, fracture type, and comorbidities were recorded. Outcomes included healthcare utilisation (e.g., prolonged length of stay [LOS>2 days], discharge disposition, 30-day readmission, and reoperation), inability to weight-bear (ITWB) on postoperative day-1 (POD-1), and any 30-day complication. Adjusted multivariate regression models evaluated associations between operative time and measured outcomes. Operative time <40 minutes was associated with lower odds of prolonged LOS (odds ratio [OR] 0.77), non-home discharge (OR 0.85), 30-day readmission (OR 0.85), and reoperation (OR 0.72). Operative time ⩾80 minutes was associated with higher odds of ITWB on POD-1 (OR 1.17). Operative time ⩾200 minutes was associated with higher odds of deep infection (OR 7.5) and wound complications (OR 3.2). The odds of blood transfusions were higher in cases ⩾60 minutes (OR1.3) and 5-fold in cases ⩾200 minutes (OR 5.4). The odds of venous thromboembolic complications were highest in the ⩾200-minute operative time category (OR 2.5). Operative time was not associated with mechanical ventilation, pneumonia, delirium, sepsis, urinary tract infection, or 30-day mortality. Increasing operative time is associated with a progressive increase in the odds of adverse outcomes following hip fracture ORIF. While a direct cause-effect relationship cannot be established, an operative time of <60 minutes could be protective. Perioperative interventions that shorten operative time without compromising fracture reduction or fixation should be considered.

Predictors of in-hospital surgical site infections in surgically managed acetabular fractures: A nationwide analysis

BackgroundA surgical site infection (SSI) rate of 4%–8% has been reported in patients who undergo open reduction and internal fixation (ORIF) for acetabular fractures. Studies have identified risk factors for SSI, but none have performed a nationwide analysis of SSI in surgically managed acetabular fracture patients. MethodsThe National Inpatient Sample (NIS) database was queried for patients who underwent ORIF for acetabular fractures from 2016 to 2019. Analysis was performed on all patients who underwent ORIF for acetabular fractures, as well as those who only underwent ORIF for isolated acetabular fractures. Clinical characteristics, hospital course, discharge disposition, and hospitalization costs were compared between groups. Multivariate regression analysis was conducted to assess predictors of SSI. Results41,725 patients undergoing acetabular fracture repair were identified, of which 490 (1.2%) developed SSI during hospitalization. Age (45.90 vs 49.90, p < 0.001) and Injury Severity Scale (5.99 vs 8.30, p < 0.001) were increased in patients who developed SSI. History of hypertension (HTN) (OR = 2.343, 95% CI 1.96–2.80, p < 0.001), longer hospital length of stay (30.27 days vs 10.00 days, p < 0.001) and total charges ($469,005 vs $193,032, p < 0.001) were associated with SSI. Lower rates of routine discharge were seen in SSI patients (OR = 0.333, 95% CI 0.260–0.426, p < 0.001). Higher rates of inpatient death were associated with SSI (OR = 2.210, 95% CI 1.172–4.17, p = 0.019). Multiple procedures in addition to acetabular fracture repair, iliac artery embolization, substance abuse, later time to internal fixation and HTN were predictive of SSI (p < 0.001). ConclusionsSeverity of injury, time to fixation, and factors associated with compromised cardiovascular integrity were predictors of SSI. Identifying patients at risk for SSI should lead to clinical maneuvers that may optimize outcome.

Cannabis Use in Patients With Distal Radius Fractures: A Moment of Unity?

As legalization of cannabis spreads, an increasing number of patients who use cannabis are being seen in the clinical setting. This study examined the impact of cannabis and tobacco use on postoperative complications following open reduction and internal fixation (ORIF) of distal radius fractures. A national, all-payer database was queried to identify patients who underwent ORIF of a distal radius fracture between 2015 and 2020 (n = 970 747). Patients were stratified into the following groups: (1) tobacco use (n = 86 941), (2) cannabis use (n = 898), (3) tobacco and cannabis use (n = 9842), and (4) neither tobacco nor cannabis use ("control", 747 892). Multivariable logistic regression was used to identify risk factors for infection, nonunion, and malunion within the first postoperative year. Concomitant use of tobacco and cannabis was associated with a higher rate of nonunion (5.0%) compared to tobacco or cannabis use alone (P < .001). Multivariate analysis identified cannabis-only use (odds ratio [OR] 1.25), tobacco-only use (OR 2.17), and concurrent tobacco and cannabis use (OR 1.78) as risk factors for infection within the first postoperative year. Similarly, cannabis-only use (OR 1.47), tobacco-only use (OR 1.92), and concurrent tobacco and cannabis use (OR 2.52) were associated with an increased risk of malunion. Cannabis use is associated with an elevated risk of infection and malunion following operative management of a distal radius fracture. Concomitant use of cannabis and tobacco poses an elevated risk of nonunion and malunion compared to tobacco use alone.

How Does Alcohol Use Disorder Impact Morbidity, Readmission Rates, and HealthCare Expenditures Following Open Reduction and Internal Fixation of Bimalleolar Fractures?

Category: Ankle; Trauma Introduction/Purpose: Bimalleolar ankle fractures are a common injury that can be treated with open reduction and internal fixation (ORIF). However, there is a paucity of literature evaluating the impact of patients with alcohol use disorder (AUD) on postoperative complications following ORIF of bimalleolar ankle fractures. Therefore, the purpose of this study is to investigate whether patients with AUD undergoing ORIF of bimalleolar ankle fractures have higher odds of (1) morbidity; (2) readmissions; and (3) costs of care. Methods: A retrospective query of the PearlDiver nationwide claims database was performed between January 2010 and October 2020. Baseline demographics were analyzed using Pearson’s Chi-Square Analyses. Multivariate binomial logistic regression was utilized to calculate the effect of AUD on 90-day medical complications. Costs of care were compared using Welch’s t-tests. A P value less than 0.001 was considered to be statistically significant. Results: The query yielded 64,563 patients within the study (AUD = 8,177; control = 56,386). Patients who have AUD were found to have significantly higher incidence and odds of developing 90-day medical complications (59.35% vs. 18.77; OR: 2.30; 95% CI: 2.16 to 2.46; p &lt; 0.0001). AUD patients were found to have higher incidences of 90-day readmissions (9.14% vs. 5.56; OR: 0.95; 95% CI: 0.86 to 1.05; p=0.361); however, this failed to reach statistical significance. Patients with AUD also incurred significantly higher day of surgery costs ($4,433.33 vs. $3,979.85, p&lt; 0.0001) and 90-day episode of care costs ($8,523.40 vs. $6,976.95, p&lt; 0.0001). Conclusion: AUD patients have higher odds of 90-day postoperative complications and costs of care following ORIF of bimalleolar ankle fractures. The findings of this study can be used by orthopaedic surgeons to reduce healthcare costs as well as improve postsurgical outcomes by educating patients who have AUD on the potential complications that they may encounter after their procedure.

Prospective Randomized Controlled Trial Between Fibula Intramedullary Nail Fixation vs Open Reduction and Internal Fixation for the Surgical Management of Unstable Ankle Fractures

Category: Ankle; Trauma Introduction/Purpose: The fundamental concept of open reduction and internal fixation (ORIF) of unstable ankle fractures was anatomical reduction and firm fixation that allow early mobilization and rehabilitation. On the other hand, ORIF of ankle fractures is associated with complications including wound dehiscence, necrosis and infection, prominent hardware and failure. Closed reduction and intramedullary fixation (CRIF) using fibula nail was emerged as additional surgical option for unstable ankle fractures especially in elderly and medical high-risk patients. We hypothesized that fibula nailing for unstable ankle fractures would have similar functional outcomes to standard ORIF. The purpose of this study is to perform a prospective randomized study to compare clinical outcomes, bone union, and postoperative complications between ORIF and CRIF using fibula nail. Methods: A total of 59 patients (32 men, 27 women) with the mean age of 50.2 years were prospectively randomized to undergo standard ORIF or fibular nailing for unstable ankle fractures: those who underwent ORIF (31 patients 14 men, 17 women) and those who underwent CRIF using fibula nail (29 patients; 18 men and 11women). Exclusion criteria of fracture characteristics were open fracture and highly comminuted fibula fractures. Functional scoring including VAS, AOFAS and FAOS were evaluated at minimum postoperative 2 years follow up. In addition, union period, reduction status of fracture and ankle mortise at postoperative CT scan, complications including wound problem and posttraumatic arthritis were evaluated. Results: The VAS, AOFAS, and all FAOS subscales were not significantly different between two group at 2 years postoperatively (all, p&gt;0.05). Significantly fewer infections and wound complication occurred in the fibula nail group. (p &lt; 0.05; ORIF group (12.9%), fibula nail group (0%)). Postoperative at fracture site of fibula was high in fibula nail group (p &lt; 0.05; ORIF group (0%), fibula nail group (13.7%)), but there were no significant differences in the status of mortise and the rate of posttraumatic arthritis (all, p&gt;0.05). Conclusion: We concluded that the fibula nail allows acceptable reduction and secure fixation of unstable ankle fracture, with low soft tissue complication rate than ORIF.

Effect of Distal Tibiofibular Syndesmosis Overcompression on the Biomechanical Properties of the Ankle Bones: An In Vitro Cadaveric Model

Category: Trauma; Ankle Introduction/Purpose: Overtightening of the distal tibiofibular syndesmosis during open reduction and internal fixation (ORIF) of ankle fractures remains a clinical concern, and there are limited data delineating the effect of syndesmosis overcompression on subsequent range of motion of the ankle joint bones. The primary objective of the current study was to determine the effect of syndesmotic overcompression on the relative range of motion (ROM) of the tibia, fibula, and talus, and to determine the syndesmotic fixation construct that most accurately restores native motion. Methods: Ten cadaveric lower limbs were utilized (78.3±13.0 yrs, 4F; 6M). A musculoskeletal simulator at ±7.5 Nm was used to test flexibility in dorsiflexion-plantarflexion, inversion-eversion, and internal-external rotation. After intact testing, syndesmotic probes were used to arthroscopically measure the intact position of the distal tibiofibular syndesmosis. The force needed to compress the syndesmosis just beyond the intact position represented the intact force (100%), and overcompression was defined as 150% of the intact force. The anterior inferior tibiofibular ligament (AITFL), interosseus membrane (IOM), and posterior inferior tibiofibular ligament (PITFL) were then sectioned. Testing was repeated for destabilized, IOM reconstruction at 100% compression and 150% overcompression, IOM reconstruction plus AITFL fixation at 100% compression and 150% overcompression, and AITFL fixation alone. ROM data was reported as a percentage of the intact condition. Repeated measures ANOVA and Bonferroni post hoc test were performed to assess differences between conditions with p&lt; 0.05. Results: Average force needed to compress the syndesmosis was 71.0 ± 22.2 N. There was a significant increase in distal tibiofibular ROM in internal and external rotation for all conditions compared to intact (Figure 1) (p &lt; 0.05). In the axial plane, reconstruction of the IOM membrane did not restore the intact condition and was similar to the destabilized treatment, regardless of compression force. The addition of AITFL fixation significantly reduced distal tibiofibular motion compared to IOM reconstructions alone, but still did not approach the intact condition. Overcompression of the syndesmosis did not significantly affect relative ROM of the ankle bones in any plane (p&gt;0.05). Changes in the proximal tibiofibular ROM were similar in magnitude and direction as the distal tibiofibular ROM for all conditions. Conclusion: In the current study, overcompression of the distal tibiofibular syndesmosis did not restrict relative ROM of the tibia, fibula, or talus. Reconstructing the AITFL in addition to the IOM decreased tibiofibular ROM, particularly in the axial plane. In the clinical setting, surgical reconstruction with dynamic fixation of the distal tibiofibular syndesmosis may result in increased ROM and mechanical stress at the proximal tibiofibular articulation.
