Early versus delayed weight-bearing following operatively treated ankle fracture (WAX): a non-inferiority, multicentre, randomised controlled trial.

BACKGROUND: After surgery for a broken ankle, patients are usually instructed to avoid walking for 6 weeks (delayed weight-bearing). Walking 2 weeks after surgery (early weight-bearing) might be a safe and preferable rehabilitation strategy. This study aimed to determine the clinical and cost effectiveness of an early weight-bearing strategy compared with a delayed weight-bearing strategy. METHODS: This was a pragmatic, multicentre, randomised, non-inferiority trial including 561 participants (aged ≥18 years) who received acute surgery for an unstable ankle fracture in 23 UK National Health Service (NHS) hospitals who were assigned to either a delayed weight-bearing (n=280) or an early weight-bearing rehabilitation strategy (n=281). Patients treated with a hindfoot nail, those who did not have protective ankle sensation (eg, peripheral neuropathy), did not have the capacity to consent, or did not have the ability to adhere to trial procedures were excluded. Neither participants nor clinicians were masked to the treatment. The primary outcome was ankle function measured using the Olerud and Molander Ankle Score (OMAS) at 4 months after randomisation, in the per-protocol population. The pre-specified non-inferiority OMAS margin was -6 points and superiority testing was included in the intention-to-treat population in the event of non-inferiority. The trial was prospectively registered with ISRCTN Registry, ISRCTN12883981, and the trial is closed to new participants. FINDINGS: Primary outcome data were collected from 480 (86%) of 561 participants. Recruitment was conducted between Jan 13, 2020, and Oct 29, 2021. At 4 months after randomisation, the mean OMAS score was 65·9 in the early weight-bearing and 61·2 in the delayed weight-bearing group and adjusted mean difference was 4·47 (95% CI 0·58 to 8·37, p=0·024; superiority testing adjusted difference 4·42, 95% CI 0·53 to 8·32, p=0·026) in favour of early weight-bearing. 46 (16%) participants in the early weight-bearing group and 39 (14%) in the delayed weight-bearing group had one or more complications (adjusted odds ratio 1·18, 95% CI 0·80 to 1·75, p=0·40). The mean costs from the perspective of the NHS and personal social services in the early and delayed weight-bearing groups were £725 and £785, respectively (mean difference -£60 [95% CI -342 to 232]). The probability that early weight-bearing is cost-effective exceeded 80%. INTERPRETATION: An early weight-bearing strategy was found to be clinically non-inferior and highly likely to be cost-effective compared with the current standard of care (delayed weight-bearing).

[Influence and risk factors of lateral hinge fracture on early effectiveness of supramalleolar osteotomy].

Objective: To evaluate the influence of lateral hinge fracture (LHF) on the early effectiveness of supramalleolar osteotomy (SMO) and to explore the related risk factors for LHF. Methods: A total of 39 patients (39 feet) with varus-type ankle osteoarthritis treated with SMO between January 2016 and December 2022 were analyzed retrospectively. There were 10 males and 29 females, aged from 41 to 71 years (mean, 57.7 years). According to Takakura stage, there were 6 feet in stage Ⅱ, 19 feet in stage Ⅲa, and 14 feet in stage Ⅲb. The LHF was recognized by the immediate postoperative X-ray film. The osteotomy healing time and the changes of pain visual analogue scale (VAS) score, American Orthopaedic Foot and Ankle Society (AOFAS) score, tibial anterior surface angle (TAS), tibial lateral surface angle (TLS), and tibiotalar angle (TT) before and after operation were compared between patients with and without LHF. The age, gender, affected side, body mass index, Takakura stage, preoperative VAS score, preoperative AOFAS score, preoperative TAS, preoperative TLS, preoperative TT, SMO correction angle, osteotomy distraction, distance from medial osteotomy to ankle joint line (MD), and distance from lateral osteotomy to ankle joint line (LD) were compared between with and without LHF patients, and further logistic regression analysis was used to screen the risk factors of LHF during SMO. Results: All patients were followed up 12-54 months (mean, 27.1 months). During operation, 13 feet developed LHF (group A) and 26 feet did not develop LHF (group B). X-ray film reexamination showed that 1 patient in group A complicated with tibial articular surface cleft fracture had delayed osteotomy and healed successfully after plaster fixation; the osteotomy of other patients healed, and there was no significant difference in healing time between the two groups ( P>0.05). At last follow-up, there were significant differences in VAS score, AOFAS score, TAS, TLS, and TT of the two groups when compared with preoperative ones ( P<0.05), but there was no significant difference in the changes of above indicators before and after operation between the two groups ( P>0.05). The differences in SMO correction angle, osteotomy distraction, and LD between with and without LHF patients were significant ( P<0.05), and further logistic regression analysis showed that excessive LD was the risk factor of LHF during SMO ( P<0.05). Conclusion: Too high or too low lateral hinge position during SMO may lead to LHF, but as long as appropriate treatment and rehabilitation measurements are taken, the early effectiveness is similar to that of patients without LHF.

Preoperative CT Scan is not Associated with Shorter Surgical Time or Improved Patient Outcomes for Trimalleolar Ankle Fractures.

Background: Posterior malleolar involvement can drastically affect patient outcomes. Literature has supported the use of preoperative Computed Tomography (CT) to assess posterior malleolar fracture morphology. The purpose of this study is to determine whether preoperative CT is associated with significant improvement in surgical time, postoperative complications, reoperation rates in trimalleolar ankle fractures. Surgeons were also asked to complete survey regarding use of CT scans to gauge utility preoperatively. Methods: Adult patients with trimalleolar ankle fractures who underwent operative fixation between 2018-2020 were retrospectively reviewed. Primary outcomes included surgical time, postoperative complications, and reoperations. Secondary outcome was presence of posterior malleolar fixation. 15 surgeons who performed ankle ORIF were surveyed to gain information regarding why or why not preoperative CT scan was obtained. Results: 288 patients with trimalleolar ankle fractures were included, 94 had preoperative CT scans (32.6%). No significant differences found in patient age, gender, BMI, smoking status between the groups that did and did not have preoperative CT scan. No significant differences were observed in AO/OTA classification between groups. Average surgical time was significantly higher in group that received a preoperative CT (114 without CT vs. 145 with CT, p<0.05). Complications (10.3% no CT vs 7.4% with CT, p=0.55) and reoperations (6.7% without CT vs. 7.4% with CT, p=0.16) not significantly different between groups. No significant difference was observed in rate of posterior malleolus fixation between groups (43.8% without CT vs 39.4% with CT; p=0.52). Of surveyed surgeons, 87% reported they don't routinely obtain preoperative CT scan for trimalleolar ankle fractures. Most common reasons for preoperative scans were deciding on approach/positioning, assessing for impaction, determining the size of the posterior malleolus. Conclusion: Although preoperative CT scans are obtained in one third of patients with operative trimalleolar ankle fractures, we did not find an improvement in surgical time, complications, and reoperation. Level of Evidence: III.

Clinical, functional and radiological outcome after osteosynthesis of ankle fractures using a specific provocation test.

BACKGROUND: Ankle fractures are frequent, and despite numerous publications on their treatment and outcome, there is a lack of precise data on the functional results in young, healthy and physically active patients. We hypothesized that patients who underwent open reduction and internal fixation (ORIF) for simple ankle fractures would have similar function compared to a healthy control group, whereas patients with complex fractures will have significant functional deficits. Furthermore, we postulate that there is a discrepancy between the radiological and the functional outcomes. METHODS: A set of specific provocation tests was developed to evaluate the postoperative possibility of weight bearing, stop-and-go activities and range of motion. In combination with three questionnaires and a radiographic evaluation, the true functional outcome and the possibility of participating in sporting activities were investigated and compared with those of an age- and sex-matched control group. RESULTS: A significant impairment was found in unilateral and simple ankle fractures. This impairment increased in tests including stop-and-go activities in combination with load bearing and with the complexity of the fractures. Concerning the subjective outcome, there was a significant adverse effect for daily activities without any difference in preoperative or postoperative sporting activity between the groups. No difference was found in the radiological assessment. CONCLUSIONS: Both simple and complex ankle fractures treated with ORIF have a significant and long-lasting impact on functional outcome in young and active patients. The radiological result is not associated with a good functional outcome. TRIAL REGISTRATION: BASEC-Nr. 2018 - 01124.

Potential Roles of Inflammation on Post-Traumatic Osteoarthritis of the Ankle.

Post-traumatic osteoarthritis of the ankle (PTOA) is frequently observed following a debilitating consequence of intra-articular ankle fractures. Numerous risk factors contribute to the pathogenesis of PTOA, including articular incongruity, joint malalignment, and concomitant soft tissue damage. Despite attempts to restore joint anatomy and manage soft tissues to avoid long-term complications after intra-articular ankle fractures, the incidence of PTOA remains markedly elevated. Inflammatory processes triggered by intra-articular ankle fractures have emerged as potential instigators that expedite the progression of PTOA. Injury to the articular cartilage and subchondral bone may lead to the release of inflammatory mediators, which can contribute to cartilage degradation and bone resorption. This study provides a narrative review on the current knowledge concerning the association between inflammation and the development of PTOA following intra-articular ankle fractures. We also discuss novel therapeutic agents that target inflammatory pathways to impede the progression of post-traumatic osteoarthritis after intra-articular ankle fractures. These medication and interventions were summarized within this review article.

Syndesmotic fixation in Weber B ankle fractures: A systematic review.

Weber Type B fractures often arise from external rotation with the foot supinated or pronated. Altered tibiofibular joint kinematics in Weber B fractures are responsible for syndesmotic damage seen in Weber B fractures. Weber B fractures are managed using open reduction and internal fixation if displaced. The syndesmosis is injured in up to 40% of cases resulting in an unstable injury with a syndesmotic diastasis. This systematic review aimed to evaluate the current literature on syndesmotic fixation in Weber B fractures, assess the outcomes and complications of syndesmotic fixation and assess the necessity of syndesmotic fixation in Weber B fractures. A search was carried out on the EMBASE, PubMed and CINAHL databases and eight studies assessing the outcomes of syndesmotic fixations versus no syndesmotic fixation with 292 Weber B ankle fractures were included in this systematic review. Results showed significant heterogeneity so a narrative review was conducted. Results of these studies showed that functional, radiological, and quality-of-life outcomes and incidences of post-traumatic osteoarthritis in patients with syndesmotic screws were similar to those of patients not managed with syndesmotic screws. Only one favoured syndesmotic fixation in all cases of diastasis. As such, syndesmotic fixation with screws may not be necessary in the management of Weber B fractures. Screws are also associated with breakage, loosening, local irritation and infections. Suture button devices and antiglide fixation techniques appear to be valid alternatives to syndesmotic screws. It was found that there was no need for routine hardware removal unless the hardware was causing significant side effects for the patient.

Comparison of operatively and nonoperatively treated isolated Weber B ankle fractures: a systematic review and meta-analysis.

BACKGROUND: Despite fractures of Isolated Weber B being prevalent, there is a lack of clarity regarding the relative effectiveness of surgical versus conservative treatment. This systematic review and meta-analysis aimed to investigate the clinical effects and complications of surgical versus conservative treatment of the Isolated Weber B ankle fractures. METHODS: This study involved thorough searches across multiple electronic databases, including PubMed, Cochrane, Embase, and Web of Science, to identify all relevant publications on Isolated Weber B ankle fractures repaired through surgical versus conservative treatment. Through a comprehensive meta-analysis, several outcomes were evaluated, including post-operative function, complications and reoperation rate. RESULT: Six articles involving 818 patients who met the inclusion criteria. Among these participants, 350 were male and 636 were female. 651 patients received conservative treatment, while 396 underwent surgical intervention. The findings indicate no significant differences in OMAS, FAOQ, PCS, MCS scores, and return to work between surgical and non-surgical treatments for isolated Weber B ankle fractures. However, compared with surgical treatment, non-surgical treatment has a higher AOFAS score(MD = -5.31, 95% CI = [-9.06, -1.55], P = 0.20, I2 = 39%), lower VAS score(MD = 0.72, 95% CI = [0.33, 1.10], P = 0.69, I2 = 0%), lower complication rate (RR = 3.06, 95% CI = [1.58, 6.01], P = 0.05, I2 = 54%), and lower reoperation rate(RR = 8.40, 95% CI = [1.57, 45.06], P = 0.05, I2 = 67%).

Ankle fracture surgery performed by orthopaedic residents without supervision has comparable outcomes to surgery performed by fellowship trained orthopaedic surgeons.

BACKGROUND: Unstable fractures often necessitate open reduction and internal fixation (ORIF), which generally yield favourable outcomes. However, the impact of surgical trainee autonomy on healthcare quality in these procedures remains uncertain. We hypothesized that surgery performed solely by residents, without supervision or participation of an attending surgeon, can provide similar outcomes to surgery performed by trauma or foot and ankle fellowship-trained orthopaedic surgeons. METHODS: A single-center cohort of an academic level-1 trauma center was retrospectively reviewed for all ankle ORIF between 2015 and 2019. Data were compared between surgery performed solely by post-graduate-year 4 to 6 residents, and surgery performed by trauma or foot and ankle fellowship-trained surgeons. Demographics, surgical parameters, preoperative and postoperative radiographs, and primary (mortality, complications, and revision surgery) and secondary outcome variables were collected and analyzed. Univariate analysis was performed to evaluate outcomes. RESULTS: A total of 460 ankle fractures were included in the study. Nonoperative cases and cases operated by senior orthopaedic surgeons who are not trauma or foot and ankle fellowship-trained orthopaedic surgeons were excluded. The average follow-up time was 58.4 months (SD ± 12.5). Univariate analysis of outcomes demonstrated no significant difference between residents and attendings in complications and reoperations rate (p = 0.690, p = 0.388). Sub-analysis by fracture pattern (Lauge-Hansen classification) and the number of malleoli involved and fixated demonstrated similar outcomes. surgery time was significantly longer in the resident group (p < 0.001). CONCLUSION: The current study demonstrates that ankle fracture surgery can be performed by trained orthopaedic surgery residents, with similar results and complication rates as surgery performed by fellowship-trained attendings. These findings provide valuable insights into surgical autonomy in residency and its role in modern clinical training and surgical education. LEVEL OF EVIDENCE: Level III - retrospective cohort study.

Syndesmotic Injuries.

Syndesmotic ankle injuries, though rare in isolation, are complex destabilizing injuries often accompanied by fractures. Misdiagnoses, particularly overlooking posterior malleolus fractures, are common in ankle sprains. Thorough physical examinations, emphasizing high fibular pain and anterior tibia palpation, aid in accurate diagnosis. Grading helps assess injury severity and guiding treatment. Initial imaging involves three ankle views, with stress radiographs enhancing accuracy. If conservative care fails, MRI reveals ligament and tendon damage. Physical therapy may suffice for functional instability; surgical intervention addresses mechanical instability. Syndesmotic fixation debates center on cortices, screw size, reduction methods, and optimal positioning.

Current Concepts in Ankle Fracture Management.

Ankle fractures are one of the more common musculoskeletal injuries that are treated by foot and ankle specialists. A thorough understanding of managing these injuries requires the ability to differentiate between stable and unstable fractures. The current literature supports the nonoperative management of stable Weber B ankle fractures, whereas unstable fractures have much better outcomes with surgical intervention. Specifically, we review the fixation strategies for the lateral, medial, and posterior malleolar fractures respectively. Finally, we discuss the current trends in postoperative management of some of the more common fracture patterns, and the safety in early weight-bearing protocols.

High Resolution MRI Confirms Torsional Injury as Mechanism for Combined Ankle and Common Fibular (Peroneal) Nerve Injuries.

Common fibular nerve (CFN) injury due to ankle fracture is an underreported complication. The authors have proposed that torsional injury to the ankle can be translated along the interosseous membrane (IOM), producing tension on the CFN at the fibular neck. A 23-year-old woman presented to our clinic for left foot drop. Three months prior, the patient sustained a fall with left ankle inversion injury while running. She was diagnosed with a minor ankle fracture and placed in an orthopaedic boot. Unfortunately, her swelling worsened and one week later the patient was diagnosed with foot drop, which was further corroborated with EMG studies showing severe CFN injury localizing to the fibular neck. Because of the lack of recovery, she underwent decompression of the CFN. She experienced immediate symptomatic relief. High resolution imaging in this case supports our previous mechanism for indirect trauma to the ankle resulting in CFN injury. (Journal of Surgical Orthopaedic Advances 33(1):053-055, 2024).

Patients with more complex ankle fractures are associated with poorer patient-reported outcome: an observational study of 11,733 patients from the Swedish Fracture Register.

BACKGROUND AND PURPOSE: Patient-reported outcome measures (PROMs) following ankle fractures, including all fracture types, have not been reported. It is therefore unclear whether fracture morphology correlates with outcome. We aimed to analyze PROMs in patients with an ankle fracture in relation to the Arbeitsgemeinschaft für Osteosynthesefragen/Orthopaedic Trauma Association (AO/OTA) fracture classification using population-based register data from the Swedish Fracture Register (SFR). METHODS: All patients aged ≥ 18 years with an ankle fracture (AO/OTA 44A1-C3) registered in the SFR between 2012 and 2019 were retrieved from the register. Patients with completed PROM questionnaires (Short Musculoskeletal Function Assessment and EuroQol-Visual Analogue Scale) on both day 0 (pre-trauma) and 1-year post-trauma were included. The difference in PROMs between day 0 and 1 year was calculated for each patient (delta value) and mean delta values were calculated at group level, based on the AO/OTA fracture classification. RESULTS: 11,733 patients with 11,751 fractures with complete PROMs were included. According to the AO/OTA classification, 21% were A fractures, 67% were B fractures and 12% were C fractures. All groups of patients, regardless of fracture class (A1-C3), displayed an impairment in PROMs after 1 year compared with day 0. Type C fractures displayed a larger impairment in PROMs at group level than type B, which in turn had a greater impairment than type A. The same pattern was seen in groups 3, 2, and 1 for A and B fractures. CONCLUSION: We found that the AO/OTA classification is prognostic, where more complex fractures were associated with poorer PROMs.

Probability of Occult Ankle Fracture Based on Radiograph-Measured Swelling.

INTRODUCTION: Pediatric ankle injuries are a common presentation in the emergency department (ED). A quarter of pediatric ankle fractures show no radiographic evidence of a fracture. Physicians often correlate non-weight bearing and tenderness with an occult fracture. We present this study to predict the probability of an occult fracture using radiographic soft-tissue swelling on initial ED radiographs. METHODS: This is a retrospective study at a Level 1 pediatric trauma center from 2021 to 22. Soft-tissue swelling between the lateral malleolus and skin was measured on radiographs, and weight-bearing status was documented. Statistical analysis was conducted using Stata software. DISCUSSION: The study period involved 32 patients with an occult fracture, with 8 (25%) diagnosed with a fracture on follow-up radiographs. The probability of an occult fracture was calculated as a function of the ankle swelling in millimeters (mm) using a computer-generated predictive model. False-negative and false-positive rates were plotted as a function of the degree of ankle swelling. CONCLUSION: Magnitude of ankle soft-tissue swelling as measured on initial ED radiographs is predictive of an occult fracture. Although weight-bearing status was not a sign of occult fracture, it improves the predictive accuracy of soft-tissue swelling.

Open Reduction and Internal Fixation for Supination-External Rotation Type IV Ankle Fractures by Means of Anterolateral and Posterolateral Approaches.

BACKGROUND: The present study aimed to analyze and compare the efficacy of the anterolateral and posterolateral approaches for surgical treatment of supination-external rotation type IV ankle fractures. METHODS: This retrospective study enrolled 60 patients (60 feet) with supination-external rotation type IV ankle fractures, including 30 patients (30 feet) treated by means of the anterolateral approach and 30 patients (30 feet) treated by means of the posterolateral approach. Postoperative clinical efficacy was compared between the groups based on operation time, intraoperative blood loss, postoperative complications, fracture healing time, visual analog scale scores, Short Form-36 Health Survey scores, and American Orthopedic Foot and Ankle Society scores. Comparisons between the two groups were performed using independent-samples t tests and analyses of variance. Intragroup differences were compared using paired t tests, and the χ2 test was used to compare categorical variables. RESULTS: All 60 included patients completed follow-up ranging from 12 to 18 months (mean duration, 14.8 ± 3.5 months). Although baseline characteristics were similar in the two groups, there were significant differences in operation time (86.73 ± 17.44 min versus 111.23 ± 10.05 min; P < .001) and intraoperative blood loss (112.60 ± 25.05 mL versus 149.47 ± 44.30 mL; P < .001). Although fracture healing time (10.90 ± 0.66 weeks versus 11.27 ± 0.94 weeks; P = .087) was shorter in the anterolateral group than in the posterolateral group, the difference was not significant. Postoperative complications occurred in one and three patients in the anterolateral and posterolateral approach groups, respectively. Visual analog scale scores were significantly lower in the anterolateral group than in the posterolateral group (1.43 ± 0.50 versus 1.83 ± 0.75; P = .019), although there was no significant difference in Short Form-36 Health Survey scores between the groups (73.63 ± 4.07 versus 72.70 ± 4.04; P = .377). However, American Orthopedic Foot and Ankle Society scores were higher in the anterolateral group than in the posterolateral group (80.43 ± 4.32 versus 75.43 ± 11.32; P = .030). CONCLUSIONS: Both the anterolateral and posterolateral approaches can achieve good results in the treatment of supination-external rotation type IV ankle fractures. Compared with the posterolateral approach, the anterolateral approach is advantageous for the treatment of supination-external rotation type IV ankle fractures given its safety and ability to reduce trauma, clear field of view revealed, and allow for exploration and repair of the inferior tibiofibular anterior syndesmosis within the same incision.

Evaluation of the horizontal approach to the medial malleolar facet in sagittal talar fractures through dorsiflexion and plantarflexion positions.

BACKGROUND: Talar fractures often require osteotomy during surgery to achieve reduction and screw fixation of the fractured fragments due to limited visualization and operating space of the talar articular surface. The objective of this study was to evaluate the horizontal approach to the medial malleolus facet by maximizing exposure through dorsiflexion and plantarflexion positions. METHODS: In dorsiflexion, plantarflexion, and functional foot positions, we respectively obtained the anterior and posterior edge lines of the projection of the medial malleolus on the medial malleolar facet. The talar model from Mimics was imported into Geomagic software for image refinement. Then Solidworks software was used to segment the medial surface of the talus and extend the edge lines from the three positions to project them onto the "semicircular" base for 2D projection. The exposed area in different positions, the percentage of total area it represents, and the anatomic location of the insertion point at the groove between the anteroposternal protrusions of the medial malleolus were calculated. RESULTS: The mean total area of the "semicircular" region on the medial malleolus surface of the talus was 542.10 ± 80.05 mm2. In the functional position, the exposed mean area of the medial malleolar facet around the medial malleolus both anteriorly and posteriorly was 141.22 ± 24.34 mm2, 167.58 ± 22.36mm2, respectively. In dorsiflexion, the mean area of the posterior aspect of the medial malleolar facet was 366.28 ± 48.12 mm2. In plantarflexion, the mean of the anterior aspect of the medial malleolar facet was 222.70 ± 35.32 mm2. The mean overlap area of unexposed area in both dorsiflexion and plantarflexion was 23.32 ± 5.94 mm2. The mean percentage of the increased exposure area in dorsiflexion and plantarflexion were 36.71 ± 3.25% and 15.13 ± 2.83%. The mean distance from the insertion point to the top of the talar dome was 10.69 ± 1.24 mm, to the medial malleolus facet border of the talar trochlea was 5.61 ± 0.96 mm, and to the tuberosity of the posterior tibiotalar portion of the deltoid ligament complex was 4.53 ± 0.64 mm. CONCLUSIONS: Within the 3D model, we measured the exposed area of the medial malleolus facet in different positions and the anatomic location of the insertion point at the medial malleolus groove. When the foot is in plantarflexion or dorsiflexion, a sufficiently large area and operating space can be exposed during surgery. The data regarding the exposed visualization area and virtual screws need to be combined with clinical experience for safer reduction and fixation of fracture fragments. Further validation of its intraoperative feasibility will require additional clinical research.

Impact of Geko Neuromuscular Stimulator on Preoperative Preparation in Ankle Fractures.

OBJECTIVE: To explore the impact of the Geko neuromuscular stimulator on preoperative preparation in patients with ankle fractures. STUDY DESIGN: Quasi-experiment study. Place and Duration of the Study: Department of Foot and Ankle Surgery and Department of Orthopaedics, Beijing Tongren Hospital, Capital Medical University, Beijing, China, between December 2020 and 2021. METHODOLOGY: This quasi-experiment study included patients with ankle fractures treated with Geko neuromuscular stimulator before surgical fixation. The primary outcome was limb swelling at 24, 48, and 72 hours (h) after admission, and the secondary outcomes were pain according to visual analogue scale (VAS) at 12, 24, and 48 hours after admission, preoperative waiting time, and comfort 4 and 72 h after admission. RESULTS: A total of 60 patients were included in the study; 30 in the conventional treatment group (mean age 41.16 ± 2.01 years) and 30 in the Geko group (mean age 40.22 ± 2.68 years). The limb swelling in patients was significantly different between the Geko and conventional treatment groups (p = 0.004). Besides, the swelling values at 48 (p < 0.001) and 72 (p < 0.001) hours were significantly lower than those at 24 hours. The pain in patients was significantly different between the Geko and conventional treatment groups (p = 0.007). Besides, the swelling values at 24 (p < 0.001) and 48 (p < 0.001) hours are significantly lower than those at 24 hours. Comfort was significantly higher at 4 h (69.54 ± 2.18 vs. 67.22 ± 3.14, p = 0.002) and 72 h [(88.50 (84.00 - 94.00) vs. 82.14 ± 3.08, p < 0.001)] after admission. The preoperative waiting time (3.52 ± 1.8 vs. 5.15 ± 2.1 hours, p = 0.002) was significantly shorter in the Geko group. CONCLUSION: The Geko neuromuscular stimulator is a useful option for preoperative preparation in patients with ankle fractures to reduce local swelling and pain and improve patients' comfort.

Maisonneuve fracture treated with short leg cast: A case report with 41-month follow-up.

RATIONALE: Maisonneuve fracture is a specific type of severe ankle injury. To our current knowledge, once a Maisonneuve fracture is diagnosed, the surgery is always recommended for fear of sequelae from inaccurate joint reconstruction. However, in this case, we treated a Maisonneuve fracture with a short leg cast, and the 41-month follow-up showed a favorable outcome with no post-traumatic osteoarthritis, chronic pain, and instability. Therefore, this case provides evidence for the feasibility of conservative treatment of Maisonneuve fracture. PATIENT CONCERNS: A female patient in her early twenties sprained her left ankle while running, suffering regional pain, swelling, and limited mobility. DIAGNOSES: We diagnosed a Maisonneuve fracture with superior fibular fracture and Volkmann tuberosity fracture, a slight separation of inferior tibiofibular syndesmosis (ITS). INTERVENTIONS: The patient rejected our surgical recommendations in favor of nonsurgical treatment, in addition to refusing immobilization of the knee. Consequently, we had to treat her with a short leg cast for 8 weeks and asked her to return for regular follow-up visits. OUTCOMES: At the final follow-up, the radiography showed complete healing of proximal fibula fracture. The patient reported no discernible subjective differences between her bilateral ankles. The range of motion of the left ankle was measured at 22° of dorsiflexion and 40° of plantarflexion. Functional assessments using Olerud-Molander ankle scale and American Orthopedic Foot and Ankle Society Ankle-Hindfoot scale both scored 100 points. Additionally, the radiographic assessment classified arthritis as stage 0 according to Morrey-Wiedeman classification. LESSONS: To avoid missing and misdiagnosing, the physical examination should always extend to 2 neighboring joints. Secondly, if a Maisonneuve fracture is suspected, further computed tomography scans, radiography, and magnetic resonance imaging can help to determine the stability of the ITS and the integrity of the lateral collateral ligaments before making therapeutic decisions. Finally, considering the lateral collateral ligaments may remain intact, we recommend stabilizing ITS by repairing the medial ligaments, which can be conducted arthroscopically and be more minimally invasive, providing an elastic fixation that aligns better with the biomechanics of the ITS which is characterized as a micro-mobile rather than fully fixed joint.

Efficacy of post-operative X-rays after operatively treated ankle fractures: What is their role?

OBJECTIVE: The utility of routine post-operative imaging in clinically asymptomatic patients is unclear. We sought to determine how frequently X-rays following operatively treated ankle fractures result in a change in management. DESIGN: Retrospective cohort study conducted with hospital electronic health record SETTING: Single level 1 trauma center in major urban city. PATIENTS/PARTICIPANTS: 193 patients with operatively treated ankle fractures at our institution between January 2020 and December 2021. MAIN OUTCOME MEASURES: Patient radiographs were categorized as surveillance X-rays and clinically indicated X-rays. Changes in management were defined as alteration in follow-up, deviation from standard post-operative protocols, or revision surgery. A logistic regression was performed looking at factors predicting whether an X-ray changes management. A cost analysis was also performed looking at the financial implications of asymptomatic surveillance of ankle fractures. RESULTS: 438 post-operative X-rays were found and included in analysis. Of these, 391 were considered surveillance X-rays and 47 clinically indicated. 23 X-rays were determined to have resulted in changes in management (18 clinically indicated, 5 taken in asymptomatic patients). The number of management changing X-rays was significantly higher in the clinically indicated group (p < 0.0001). The only factor associated with whether an X-ray changed management was whether the patient was symptomatic at the visit (p < 0.0001). Asymptomatic surveillance X-rays cost our institution 21,825.62 USD per year. CONCLUSIONS: Radiographs in clinically asymptomatic patients with operatively managed ankle fractures have a low likelihood of changing management. Such imaging represents costs to the healthcare system, increased time for patients during clinic visits, and radiation exposure. The use of screening radiographic studies remains commonplace because the risk of delayed diagnosis is great, and the goal of any surgeon should be the swift identification of complications in order to minimize patient morbidity. Future surveillance protocols should consider the findings of this and other studies on the use of screening radiographs and strike a careful balance between minimizing unnecessary imaging, maximizing early complication detection, and ensuring a personalized approach towards patient-level factors to optimize care and efficiency for both patient and health system. LEVEL OF EVIDENCE: Level III.

Differences in Intraoperative Fluoroscopic Radiation Exposure During Ankle Fracture Open Reduction and Internal Fixation Between Orthopaedic Surgery and Podiatry.

Surgical ankle fractures pose a unique situation because both podiatrists and orthopaedic surgeons manage these injuries. Intraoperative fluoroscopy is routinely used; however, excessive radiation can be harmful to both the patient and the surgical team. The primary goal of this study was to determine whether there is a difference in the amount of intraoperative radiation exposure during ankle fracture open reduction and internal fixation (ORIF) when performed by orthopaedic surgeons versus podiatrists. This is a retrospective review of patients who underwent ankle fracture ORIF at an urban level I trauma center between January 1st, 2018, and April 1st, 2023. The electronic health record was queried using International Classification of Diseases nine and 10 codes associated with ankle fractures. Patients aged older than 18 years with an ankle fracture managed surgically were included. Subjects were then stratified by procedure. The mean total radiation dose (mRad) and mean total fluoroscopic time (seconds) were then compared between those performed by orthopaedic surgeons and podiatrists. Of the 333 included procedures, 186 were done by orthopaedic surgeons and 147 were done by podiatrists. Using multiple linear regression analysis to control for age, sex, race, ethnicity, and body mass index, patients undergoing isolated malleolus ORIF with syndesmosis repair performed by orthopaedic surgery were found to have a significantly lower mean fluoroscopic time compared with those performed by podiatry (68.4 s versus 104.8 s; P = 0.028). In addition, trimalleolar ORIF with syndesmotic repair performed by orthopaedic surgery had a significantly lower mean total radiation dose compared with those performed by podiatry (244.6 mRad v 565.6 mRad; P = 0.009). Patients and surgical teams are exposed to markedly less radiation in isolated malleolar and trimalleolar fracture ORIF with syndesmosis repair when performed by an orthopaedic surgeon as compared with those performed by a podiatrist.
