BackgroundPrecise correlations between medial malleolar fracture geometry and fracture mechanism have not been thoroughly described. This study sought to determine the prevalence of different medial malleolar fracture types and to elucidate the association between fracture geometry and fracture mechanism. MethodsThe records of 112 medial malleolar ankle fractures were reviewed. For each fracture, the direction of the fracture line in the medial malleolus (transverse, oblique, vertical, or comminuted), the Lauge-Hansen classification, and the presence or absence of syndesmotic injury was recorded. Bivariate correlation analysis was performed to determine if correlations existed. ResultsTransverse fractures were the most prevalent type of medial malleolar fracture [ n = 64 (57%)], and they correlated with supination-external rotation injuries. These were followed by oblique fractures [29 (26)], which correlated with pronation-external rotation injuries [29 (26)], and vertical fractures [7 (6)], which correlated with supination-adduction injuries [9 (8)]. Comminuted fractures [12 (11)] and pronation-abduction injuries [22 (20)] did not correlate with any other categories. Syndesmotic injuries were correlated with transverse fractures, bimalleolar fractures, and pronation-external rotation injuries. ConclusionMedial malleolar fractures can be divided into four fracture types: transverse fractures, which correlated with supination-external rotation injuries; oblique fractures, which correlated with pronation-external rotation injuries; vertical fractures, which correlated with supination-adduction injuries; and comminuted fractures, which did not correlate with a particular type of injury. Syndesmotic injury was positively correlated with transverse fractures of the medial malleolus, bimalleolar fractures, and pronation-external rotation injuries. These findings suggest that medial malleolar fracture geometry can provide valuable information for the clinician when classifying and managing ankle fractures. 相似文献

BackgroundWe assessed the frequency and types of ankle fractures that frequently occur during parachute landings of special operation unit personnel and analyzed the causes. MethodsFifty-six members of the special force brigade of the military who had sustained ankle fractures during parachute landings between January 2005 and April 2010 were retrospectively analyzed. The injury sites and fracture sites were identified and the fracture types were categorized by the Lauge-Hansen and Weber classifications. Follow-up surveys were performed with respect to the American Orthopedic Foot and Ankle Society ankle-hindfoot score, patient satisfaction, and return to preinjury activity. ResultsThe patients were all males with a mean age of 23.6 years. There were 28 right and 28 left ankle fractures. Twenty-two patients had simple fractures and 34 patients had comminuted fractures. The average number of injury and fractures sites per person was 2.07 (116 injuries including a syndesmosis injury and a deltoid injury) and 1.75 (98 fracture sites), respectively. Twenty-three cases (41.07%) were accompanied by posterior malleolar fractures. Fifty-five patients underwent surgery; of these, 30 had plate internal fixations. Weber type A, B, and C fractures were found in 4, 38, and 14 cases, respectively. Based on the Lauge-Hansen classification, supination-external rotation injuries were found in 20 cases, supination-adduction injuries in 22 cases, pronation-external rotation injuries in 11 cases, tibiofibular fractures in 2 cases, and simple medial malleolar fractures in 2 cases. The mean follow-up period was 23.8 months, and the average follow-up American Orthopedic Foot and Ankle Society ankle-hindfoot score was 85.42. Forty-five patients (80.36%) reported excellent or good satisfaction with the outcome. ConclusionsPosterior malleolar fractures occurred in 41.07% of ankle fractures sustained in parachute landings. Because most of the ankle fractures in parachute injuries were compound fractures, most cases had to undergo surgical repairs. 相似文献

PurposeThe impact of isolated malleolar fractures on the intra-articular load distribution within the ankle joint has been studied in several biomechanical cadaver studies during the last decades. Recently, computed tomography osteoabsorptiometry (CT-OAM) has been proposed as a valuable tool to assess intra-articular joint load distribution in vivo. The purpose of this retrospective matched pair analysis was to apply CT-OAM to evaluate in vivo changes of talar load distribution after lateral malleolar fractures in patients treated with open anatomic reduction and internal fixation (ORIF) compared to patients treated non-operatively. MethodsTen matched pairs of patients with isolated lateral malleolar fractures with a maximum fracture dislocation of 3 mm and a median follow-up of 42 month were included into the study. Patients were matched for age, gender, and fracture dislocation. Range of ankle motion (ROM), the AOFAS hindfoot score and the Short Form 36 (SF-36) were evaluated.CT-OAM analysis of the injured and the uninjured contralateral ankles were performed. ResultsPatients treated with ORIF showed a significant lower ROM compared to the uninjured contralateral ankle. No differences were found regarding clinical scores between patients treated by ORIF and those treated non-operatively.CT-OAM analysis showed symmetrical distribution of subchondral bone mineralization in comparison to the uninjured contralateral ankles for both groups of patients. ConclusionsThe data of this study suggest that isolated lateral malleolar fractures with fracture gaps up to 3 mm are not associated with a change of the tibio-talar joint load distribution in vivo. Therefore, patients with isolated minimally displaced lateral malleolar fractures may achieve good clinical long-term outcome following non-operative treatment.Level of Evidence: Level III, retrospective cohort study 相似文献

In 17 of 148 fractures of the leg (11.5 per cent) we found an isolated fracture of the posterior malleolus of the tibia as a sign of associated injury of the ankle joint. In two cases there was even disruption of the anterior syndesmosis. All fractures of the tibia were oblique and closed without severe soft tissue injury and caused by a rotational force with low energy. In fracture of the leg of this specific type a radiological examination of the ankle joint in search for a posterior malleolar fracture is needed. If present, instability of the distal tibio-fibular joint must be excluded. 相似文献

PurposeMost patients with ankle arthrosis have a history of ankle fracture. Evaluation of malleolar fractures solely on X-ray may be insufficient to identify many pathologies that potentially contribute to ankle arthrosis, with a consequent poor prognosis. We investigated the pathologies that may be overlooked in malleolar fractures evaluated solely on plain X-ray. MethodsDuring 2012–2019, 65,479 patients attended our Emergency Department, of which 6508 complained of an ankle joint problem. X-rays indicated a fracture in 454 of these patients. Patients with isolated, simple fracture of the lateral or medial malleolus, or talus, or a history of surgery to this area were excluded; finally, 67 patients were enrolled (31 males, 36 females; mean age: 51,2 years (range: 9–83 years). Patients underwent X-ray imaging of both ankles in anterio-posterior, lateral, and Mortise views, as well as CT scans. Three independent observers with varied experience in diagnostic imaging (orthopaedic resident, experienced orthopaedic surgeon, and musculoskeletal radiologist) evaluated X-ray images blinded to CT scans. Their diagnoses were subsequently compared with CT findings. ResultsModeling results indicated that about 40% [95% CI: 32%, 50%] of pathologies may be overlooked based on X-ray evaluation, regardless of evaluator experience. The most frequently overlooked injuries were: Tillaux fracture, Pillon fracture, loose bodies and syndesmosis injury. All of that missed pathologies required dedicated treatment and could be easily missed with standard surgical approach. ConclusionEvaluation of malleolar fractures by X-ray only inevitably results in overlooking of many pathologies, despite the clinician’s experience. Routine CT scan can help to improve the accuracy of diagnosis, and thereby reduce the risk of ankle osteoarthrosis. 相似文献

IntroductionRecent studies on posterior malleolar fractures mainly focus on the reduction quality and fixation of the posterior fragment since it contributes to ankle stability and articular congruency. However, the association of pre-and postoperative factors considering the whole ankle joint in postoperative functional outcomes remains unclear. Therefore, this study aimed to examine the association between pre-and postoperative variables for postoperative functional outcomes in patients with posterior malleolar fragments (classified as Haraguchi type I or II) and considered the association between reduction and fixation for small posterior malleolar fragments of less than 25% of the intra-articular surface. MethodsThis multicenter retrospective cohort study included 110 adult patients who underwent internal fixation for ankle fractures with posterior malleolar fragments. The primary outcome was the American Orthopaedic Foot and Ankle Society (AOFAS) score 12-months postoperatively. As pre-and postoperative variables, the preoperative demographic data, radiographic findings, operative method, postoperative radiographic findings, and complications were evaluated. In addition, univariable and multivariable logistic regression analyses were conducted to examine the association between pre-and postoperative variables and AOFAS scores. ResultsTwenty-four (21.8%) cases had postoperative complications. Univariate analysis showed that age was significantly according to AOFAS score-stratified groups in patients with Haraguchi type II fractures. Multivariable logistic regression analysis using bootstrapping in the Haraguchi type II group showed that postoperative complications were significantly associated with low AOFAS scores, indicating poor functionality. In both fracture types, postoperative complications had the highest odds ratio among the explanatory variables. In patients with small posterior malleolar fragments, fragment reduction, fixation, and ankle stability were not associated with AOFAS scores. ConclusionsOur results suggest that postoperative complications were associated with AOFAS scores at postoperative 12 months in patients with ankle fractures with posterior malleolar fragments. In patients with small posterior malleolar fragments, reduction and fixation were not associated with AOFAS scores. Therefore, clinical decisions for posterior fragment fixation should be made based on the possible risk of complications related to the surgical procedures in addition to the posterior malleolar fragment size. 相似文献

IntroductionRotational type ankle fractures with a concomitant fracture of the posterior malleolus are associated with a poorer clinical outcome as compared to ankle fractures without. However, clinical implications of posterior malleolar (PM) fracture morphology and pattern have yet to be established. Many studies on this subject report on fragment size, rather than fracture morphology based on computed tomography (CT). The overall purpose of the current study was to elucidate the correlation of PM fracture morphology and functional outcome, assessed with CT imaging and not with –unreliable- plain radiographs. MethodsBetween January 2010 and May 2014, 194 patients with an operatively (ORIF) treated ankle fracture, were prospectively included in the randomized clinical EF3X-trial at our Level-I trauma center. The current study retrospectively included 73 patients with rotational type ankle fractures and concomitant fractures of the posterior malleolus. According to the CT-based Haraguchi fracture morphology, all patients were divided into three groups: 20 Type I (large posterolateral-oblique), 21 Type II (transverse medial-extension) and 32 Type III (small-shell fragment). At 12 weeks, 1 year and 2 years postoperatively the Foot and Ankle Outcome Scores (FAOS ) and SF-36 scores were obtained, with the FAOS domain scores at two years postoperative as primary study outcome. Statistical analysis included a multivariate regression and secondary a mixed model analysis. ResultsHaraguchi Type II PM ankle fractures demonstrated significantly poorer outcome scores at two years follow-up compared to Haraguchi Types I and III. Mean FAOS domain scores at two years follow-up showed to be significantly worse in Haraguchi Type II as compared to Type III, respectively: Symptoms 48.2 versus 61.7 (p = 0.03), Pain 58.5 versus 84.4 (p < 0.01), Activities of Daily Living (ADL) 64.1 versus 90.5 (p < 0.01). ConclusionPosterior malleolar ankle fractures with medial extension of the fracture line (i.e. Haraguchi Type II) are associated with significantly poorer functional outcomes. The current dogma to fix PM fractures that involve at least 25–33% of the tibial plafond may be challenged, as posterior malleolar fracture pattern and morphology - rather than fragment size - seem to determine outcome. 相似文献

BackgroundThe optimal method for the determination of ankle stability remains controversial in rotational ankle fractures without medial bony injury. Questions/PurposesThe purposes of this study were to (1) evaluate whether posterior malleolar (PM) fracture displacement is associated with deltoid ligament injury in supination-external rotation (SER) ankle fractures and (2) compare the diagnostic accuracy of PM displacement and magnetic resonance imaging (MRI) evaluation of the deep deltoid ligament in identifying fractures with deltoid ligament incompetence. MethodsPatients with rotational bimalleolar injuries containing lateral malleolar and PM fractures without bony medial injury were included. After operative lateral and PM fixation, an external rotation stress test was performed to evaluate deltoid ligament stability. Operative dictations were reviewed to confirm injury pattern, stability on stress test, and visual inspection of the deltoid ligament. Maximum PM displacement was assessed on lateral X-ray. Pre-operative MRI of the ankle was performed following closed reduction and splinting. ResultsThe final cohort consisted of 13 trimalleolar equivalent fractures (torn deltoid ligament) and 20 bimalleolar fractures (medial malleolus and deltoid ligament intact). Average PM displacement was significantly higher for SER trimalleolar equivalent patterns when measured on lateral X-ray. The sensitivity of detecting trimalleolar equivalent fracture was higher on all reported X-ray findings than the sensitivity obtained by the reported MRI findings of deltoid ligament injury. ConclusionPM displacement on X-ray is a useful adjuvant along with external rotation stress radiography and MRI evaluation of deep deltoid integrity to distinguish between stable and unstable fracture patterns and thus helps facilitate treatment decisions. 相似文献

BackgroundExtensive research has been conducted concerning the epidemiology of fractures of the calcaneus and ankle. However, less work has characterized the population sustaining talus fractures, necessitating the analysis of a large, national sample to assess the presentation of this important injury. MethodsThe current study included adult patients from the 2011 through 2015 National Trauma Data Bank (NTDB) who had talus fractures. Modified Charlson Comorbidity Index (CCI), mechanism of injury (MOI), Injury Severity Score (ISS), and associated injuries were evaluated. ResultsOut of 25,615 talus fracture patients, 15,607 (61%) were males. The age distribution showed a general decline in frequency as age increased after a peak incidence at 21 years of age. As expected, CCI increased as age increased. The mechanism of injury analysis showed a decline in motor vehicle accidents (MVAs) and an increase in falls as age increased. ISS was generally higher for MVAs compared to falls and other injuries.Overall, 89% of patients with a talus fracture had an associated injury. Among associated bony injuries, non-talus lower extremity fractures were common, with ankle fractures (noted in 42.7%) and calcaneus fractures (noted in 27.8%) being the most notable. The most common associated internal organ injuries were lung (noted in 19.0%) and intracranial injuries (noted in 14.9%). ConclusionThis large cohort of patients with talus fractures defined the demographics of those who sustain this injury and demonstrated ankle and calcaneus fractures to be the most commonly associated injuries. Other associated orthopaedic and non-orthopaedic injuries were also defined. In fact, the incidence of associated lumbar spine fracture was similar to that seen for calcaneus fractures (14%) and nearly 1 in 5 patients had a thoracic organ injury. Clinicians need to maintain a high suspicion for such associated injuries for those who present with talus fractures. Level of EvidenceLevel II, retrospective study 相似文献

AimsOngoing controversy exists over the indications and benefits of posterior malleolar fixation in ankle fractures. The aim of this pragmatic study was to evaluate the outcomes of posterior malleolar fracture fixation in ankle fractures in the setting of a major trauma centre. Our hypothesis is that posterior malleolus fixation leads to improved clinical outcomes. MethodsA total of 320 patients were identified with operatively treated ankle fractures involving a posterior malleolus component, at our institution between January 2012 and January 2018, ensuring a minimum 2 year follow-up. Of these patients, 160 had the posterior malleolus fixed as part of their surgery and 160 did not. Patient demographics, surgical details and complications were assessed. The Manchester-Oxford Foot Questionnaire (MOXFQ) was the primary patient outcome measure. ResultsFixation of the posterior malleolus was associated with a statistically significant improvement in patient outcomes. Mean MOXFQ score in the unfixed posterior malleolus group was 24.03 (0 - 62), compared to 20.10 (0 - 67) in the fixed posterior malleolus group ( p = 0.04). Outcomes were worse with increasing size of posterior malleolar fragment. Metalwork-related issues were higher in the posterior malleolus fixed group (24/160 (15%) versus 10/160 (6.2%)) and re-operation rate was double. ConclusionThis study demonstrates that in the practical setting of a major trauma unit, fixation of the posterior malleolar fracture leads to improved patient outcomes but with increased metalwork risks and reoperation rates. 相似文献

Trimalleolar ankle fractures are unstable injuries with possible syndesmotic disruption. Recent data have described inherent morbidity associated with screw fixation of the syndesmosis, including the potential for malreduction, hardware irritation, and post-traumatic arthritis. The posterior malleolus is an important soft tissue attachment for the posterior inferior syndesmosis ligament. We hypothesized that fixation of a sizable posterior malleolar (PM) fracture in supination external rotation type IV (SER IV) ankle fractures would act to stabilize the syndesmosis and minimize or eliminate the need for trans-syndesmotic fixation. A retrospective review of trimalleolar ankle fractures surgically treated from October 2006 to April of 2011 was performed. A total of 143 trimalleolar ankle fractures were identified, and 97 were classified as SER IV. Of the 97 patients, 74 (76.3%) had a sizable PM fragment. Syndesmotic fixation was required in 7 of 34 (20%) and 27 of 40 (68%), respectively, when the PM was fixed versus not fixed ( p = .0002). When the PM was indirectly reduced using an anterior to posterior screw, 7 of 15 patients (46.7%) required syndesmotic fixation compared with none of 19 patients when the PM fragment was fixated with direct posterior lateral plate fixation ( p = .0012). Fixation of the PM fracture in SER IV ankle fractures can restore syndesmotic stability and, thus, lower the rate of syndesmotic fixation. We found that fixation of a sizable PM fragment in SER IV or equivalent injuries through posterolateral plating can eliminate the need for syndesmotic screw fixation. 相似文献

BackgroundThe purpose of the study is to investigatethe prevalence of posterior malleolus intercalary fragment (ICF) in adult ankle fractures; to analyze the morphological characteristics of ICF; and its mechanism. MethodsRetrospectively, 247 cases of posterior malleolus fractures (PMF) were included in 369 cases of adult ankle fractures. The prevalence of ICF, relationship between type of ankle fracture, posterior malleolar fracture and the ICF was studied. ResultsAmong 369 cases, the ICF was found in 43% of the PMF and 29% of the hospitalized unstable ankle fractures. Position of ICF is posterolateral in 68 (64%), mid posterior in 20 (19%) and posteromedial in 18 (17%) cases. The prevalence of ICF was 70% in Bartoníček classification type III fractures, which was significantly higher than type I, II and IV. ConclusionsThe highest incidence occurs in Bartoníček III type fracture. The study helps in further understanding and treatment of the PMF. Level of evidenceLevel IV, case series. 相似文献

BackroundThe clinical relevance and treatment of syndesmosis injury in supination-external rotation (SER) ankle fractures are controversial. MethodsAfter malleolar fixation 24 SER 4 ankle fracture patients with unstable syndesmosis in external rotation stress test were randomised to syndesmosis transfixation with a screw (13 patients) or no fixation (11 patients). Mean follow-up time was 9.7 years (range, 8.9–11.0). The primary outcome measure was the Olerud-Molander Ankle Outcome Score (OMAS). Secondary outcome measures included ankle mortise congruity and degenerative osteoarthritis, 100-mm visual analogue scale for function and pain, RAND 36-Item Health Survey, and range of motion. ResultsMean OMAS in the syndesmosis transfixation group was 87.3 (SD 15.5) and in the no-syndesmosis-fixation group 89.0 (SD 16.0) (difference between means 1.8, 95% CI ?10.4–14.0, P = 0.76). There were no differences between the two groups in secondary outcome measures. ConclusionWith the numbers available, SER 4 ankle fractures with unstable syndesmosis can be treated with malleolar fixation only, with good to excellent long-term functional outcome. 相似文献

BackgroundDespite advances in malleolar fractures treatment, the overall risk to develop posttraumatic ankle osteoarthritis after 20 years is almost 40%, especially bimalleolar Weber type B and C fractures and fractures involving the posterior tibial rim. MethodsWe performed a systematic literature review of clinical studies targeting the changes in cartilage, synovial cells and synovial fluid after malleolar fractures. ResultsThe acute ankle injury initiates a sequence of biological events potentially leading to progressive articular surface damage resulting from inflammatory changes in cartilage, synovial tissue and synovial fluid. ConclusionA better understanding of the molecular and histological changes induced by acute trauma may potentially lead to novel, targeted treatment of malleolar fractures besides anatomical reduction and adequate stabilization. 相似文献

Ankle fractures and their mechanisms of injury can be complex. We report a case of a patient with an uncertain mechanism of injury and an uncommon combination of lower extremity fractures, which fit the criteria for a Lauge-Hansen classification pronation-external-rotation fracture, Maisonneuve fracture, Wagstaffe fracture, and posterior pilon fracture. Plain radiographs and computed tomography scan revealed Chaput tubercle avulsion fractures, an anterior distal fibular fracture fragment, multiple lateral malleolar fractures, a posterior malleolar fracture fragment with proximal displacement, a die-punch fragment between the posterior malleolar fragment and the tibia, a proximal fibular fracture, and possible ankle syndesmotic diastasis. Intraoperative hook test was negative after fixation of the fractures, so syndesmotic fixation was not performed. At 3-month follow-up, plain radiographs showed obvious syndesmotic diastasis. At 1-year follow-up, symptoms persisted and syndesmotic fusion was recommended but declined by the patient. This case demonstrates that both ankle fractures and their mechanisms of injury can be remarkably complex and confusing, posterior pilon fractures can occur along with pronation-external-rotation ankle fractures, syndesmotic fixation should be considered for all patients with Maisonneuve fractures, reliance on the hook test for surgical management decisions may not always be reliable, and there exists a need for a more accurate and reliable intraoperative test to determine the presence of ankle syndesmotic injury. 相似文献

BackgroundIntramedullary nail (IMN) fixation of the fibula in malleolar ankle fractures has been shown to result in less wound complications then plate fixation. Therefore, IMN fibula fixation may also be associated with lower rates of wound complications when used for higher-risk pilon fractures. The purpose of this study was to compare complications of fibula IMN fixation in pilon versus malleolar ankle fractures. MethodsA retrospective cohort comparison was performed at an urban level one trauma center involving fibula fractures in 47 patients with AO/Orthopaedic Trauma Association (OTA) type 43 fractures and 48 patients with AO/OTA type 44 fractures being treated with fibula IMN fixation. Complications, fibula-specific complications, revision surgeries, and implant removals were reviewed. ResultsThere was no detectable difference in complications (27% vs. 23%, 95% confidence interval of the odds ratio (CIOR) 0.5 to 3.2), fibular-specific complications (6% vs. 10%, CIOR 0.1 to 3.5), revision surgeries (4% vs. 4%, CIOR 0.1 to 7.5), or symptomatic fibula implant removals (13% vs. 21%, CIOR 0.1 to 1.6) between pilon and ankle fracture groups, respectively. There was one (2%) fibular nonunion and one wound complication (2%) in each of the fracture groups. ConclusionFibula IMN fixation of pilon versus ankle fractures resulted in a similar number of complications. Comparative studies of fibula IMN and plate fixation are necessary to determine if the benefits of fibula IMN in ankle fractures extends to pilon fractures.

BackgroundAssociations of tendon injuries with ankle and hindfoot fractures is a current concern and recent research has linked specific fractures with specific tendon injuries, despite its functional impact being unknown. The purpose of this study is to assess that impact. MethodsComputed tomography scans of patients with ankle and hindfoot fractures were reviewed for tendon injuries. Patients were clinically evaluated with the Visual Analogue Scale (VAS) and the Manchester–Oxford Foot Questionnaire (MOXFQ), via a telephonic interview. ResultsEighty-five patients were included in the study. The mean age was of 49.9 ± 16.5 (14–80) years and there were 43 females (50,6%). Mean follow-up was of 43,7 ± 15,1 (24,4–82,2) months. Tendon injuries were identified in 23 patients (27,1%) and the most common lesion was tendon entrapment. The tibialis posterior tendon (TP) was injured in 18 patients (21,2%) and comprised 58,1% of all tendon injuries. Tendon injuries were mostly associated with pilon fractures, which was the most common fracture type (44,7%). There was no clinical difference between patients with a tendon injury [VAS of 4,3 ± 2,6 (0–8) and MOXFQ score of 35,1 ± 22,4 (5–80)], and those without [VAS of 3,9 ± 2,5 (0–10) and MOXFQ of 34,3 ± 26,0 (0–95), respectively (p = 0,281 and 0,689)]. ConclusionTendon injuries were present in 27% of patients with ankle and hindfoot injuries. The most frequently injured tendon was the TP in association with pilon fractures, with entrapment being the most common lesion. These lesions, however, do not seem to reflect in a worse functional outcome at two years of follow-up. 相似文献

IntroductionMedial malleolar stress fractures are relatively uncommon. This report describes the successful treatment of nonunion of a medial malleolar stress fracture due to chronic lateral ankle instability. Presentation of caseA 13-year-old middle school student who belonged to a football club presented to our clinic with chronic medial left ankle pain lasting over a year. He had sprained his left ankle several times 6 years earlier. A plain anteroposterior ankle radiograph showed a vertical fracture line in the medial malleolus involving the epiphyseal plate, and computed tomography demonstrated the vertical fracture seen on the plain radiographs and bone sclerosis at the fracture site. We performed internal fixation for nonunion of the medial malleolar stress fracture with arthroscopic modified Broström for lateral ankle instability. Two years after surgery, the Self-Administered Foot Evaluation Questionnaire improved in all parameters, and both the anterior drawer and varus stress tests were negative. DiscussionEarly diagnosis of medial malleolar stress fracture is important for a rapid return to sports. Magnetic resonance imaging is helpful for early diagnosis. Because lateral ankle instability can cause medial malleolar stress fracture, arthroscopic modified Broström procedure is meaningful for medial malleolar stress fracture with lateral ankle instability. ConclusionInternal fixation and the arthroscopic modified Broström procedure could achieve good clinical outcomes for medial malleolar stress fractures with lateral ankle instability. 相似文献
