Materials and Methods: Sixty-three patients were included in my retrospective study, and all with a displaced fracture of the ankle caused by high energy trauma were treated by open reduction and rigid internal fixation. Results: After follow-up at six weeks and twelve weeks, the results were satisfactory in fifty-five percent out of all the sixty-three patients. Conclusions and Recommendations: Ankle fractures occur mainly in young males of the age group between 26 and 35 years, mostly caused by fall down and motor vehicle accident.展开更多

METHODS: The patients of ARIF(n = 16) or ORIF(n = 29) to treat unstable ankle fracture between 2006 and 2014 were reviewed retrospectively. Baseline data, including age, sex, type of injury, immediate postoperative fracture configuration(assessed on X-rays and graded by widest gap and largest step-off of any intraarticular site), bone quality [assessed with bone mineral density(BMD) testing] and arthritic changes on X-rays following surgical treatments were recorded for each group.RESULTS: Immediate-postoperative fracture configurations did not differ significantly between the ARIF and ORIF groups. There were anatomic alignments as 8(50%) and 8(27.6%) patients in ARIF and ORIF groups(P = 0.539) respectively. There were acceptable alignments as 12(75%) and 17(58.6%) patients in ARIF and ORIF groups(P = 0.341) respectively. The arthritic changes in follow-up period as at least 16 wk following the surgeries were shown as 6(75%) and 10(83.3%) patients in ARIF and ORIF groups(P = 0.300) respectively. Significantly more BMD tests were performed in patients aged > 60 years(P < 0.001), ARIF patients(P = 0.021), and female patients(P = 0.029). There was no significant difference in BMD test t scores between the two groups. CONCLUSION: Ankle fracture configurations following surgeries are similar between ARIF and ORIF groups, suggesting that ARIF is not superior to ORIF in treatment of unstable ankle fractures.展开更多

Ankle fractures usually affect young men and older women, however, below the age of 50;ankle fractures are the commonest in men. Two commonly used classification systems for ankle fractures include the danis weber AO classification and the Lauge-Hansen classification. There is biomechanical evidence that posterior non-locking plates are superior in stability than laterally placed plates;however there is little clinical evidence. There are several different methods of ankle fracture fixation, however the goal of treatment remains a stable anatomic reduction of talus in the ankle mortise and correction of the fibula length as a 1 mm lateral shift of the talus in the ankle mortise reduces the contact area by 42%, and displacement (or shortening) of the fibula more than 2 mm will lead to significant increases in joint contact pressures. Further research both biomechanically and clinically needs to be undertaken in order to clarify a preferable choice of fixation.展开更多

Materials and methods: Forty-six patients with Weber A and low Weber B displaced lateral malleolus fractures who underwent closed reduction and percutaneous internal fixation with an intramedullary, fully threaded, screw were retrospectively reviewed. A 3.5-mm, fully threaded, selftapping bone screw (stainless steel from Pelvic Set Synthes). The length of the screw varies between 100 mm and 120 mm, depending on the fracture location and pattern. Results: All fractures united within an average time to union of 8.2 weeks. In all patients the average time to full weight bearing was 6.8 weeks, whereas that in patients with isolated lateral malleolus fractures was 4.5 weeks. There were no deep wound infections or complaints of painful hardware. At latest follow-up, functional results were excellent in, 25 patients (54.3%) good in 20 (43.5%), fair in (2.2%). Conclusion: If reduction of the lateral malleolus fracture can be obtained in a closed fashion (with the aid of an image x-ray intensifier), we believe that fixation may be performed with an axial screw percutaneously. This technique is quick, safe and easy to do with less complication.展开更多

Initially w...Introduction: Neglected ankle fractures are common in our regions. Patients first consult traditional healers and it is when the signs persist that they consult the surgeon for a swollen and painful ankle. Initially we always performed anatomical repairs with osteosynthesis, but the majority of patients still complained of pain and disability. We wondered whether a primary arthrodesis would not be indicated in old ankle fractures to avoid disabling pain for patients. We therefore performed a series of arthrodesis on neglected post-traumatic ankles. The objective of our study was to describe the results of arthrodesis on an old post-traumatic ankle and to propose a therapeutic indication in the face of any neglected ankle fracture. Material and Method: This was a prospective study over 8 years between December 2012 and November 2020, involving 36 cases of neglected ankle fractures treated by arthrodesis using Meary’s technique. We used AOFAS (American Orthopedic Foot and Ankle Score) preoperatively and postoperatively for an objective assessment. Results: The average follow-up was 4.2 years and our results were satisfactory (94.4%) with an average AOFAS score ranging from 27.8 preoperatively to 76.7 postoperatively. The fusion rate was 97.2%. Discussion: Arthrodesis appears here as an important alternative in the treatment of neglected ankle fractures with significant trophic disorders.展开更多

For the management of posterior malleolus fractures, more studies are still required, though it is already well-recognized for medial and lateral structure. Therefore, fracture of posterior malleolus is striking subject of study among orthopedic surgeons. Most orthopedic surgeons recommend fixing the posterior malleolus fracture if it is larger than 25% to 33% of the distal articular surface. Further attention is required for the reduction and fixation of fractures involving posterior malleolus. Several approaches and methods for fixation of posterior malleolus have been defined in the literature. Previously, the most common method of fixation of the posterior malleolus is by indirect reduction and antero-posterior screws, it is minimally invasive, the anterior incision does not allow satisfactory visualization of the fragment, so good anatomical reduction is difficult to achieve thorough this approach. Operative management goals to reach a stable ankle with maximal function, decrease the risk of post-traumatic degenerative changes, and diminish the risk of complication. Nowadays, posterolateral approach is gaining the popularity due to adequate visualization and accurate anatomic reduction.展开更多
文摘BACKGROUND The recovery of limb function after ankle fracture surgery is a gradual process.The main purpose of implementing early functional exercise,joint mobility,muscle contraction function,passive ankle flexion and extension exercises,or physical factor therapy techniques is to achieve the rapid recovery of normal physiological limb function.However,currently the most effective rehabilitation training method is staged limb functional exercise,which promotes rapid recovery of limb function while preventing adverse consequences caused by overwork or insufficient training.Staged limb functional exercise divides the rehabilitation process into multiple stages,each of which has specific training objectives and contents.This method helps patients gradually restore limb function.Nevertheless,some patients still exhibit poor limb function after standardized exercise.Therefore,a functional evaluation should be performed to analyze the impact of staged functional training after ankle fracture surgery.AIM To perform a functional evaluation and determine the influencing factors of staged functional training in patients with ankle fracture.METHODS A retrospective study enrolled 150 patients who underwent surgical treatment for ankle fracture from May 2020 to May 2022 at our hospital.Univariate and multivariate linear regression analyses were performed on general data,functional exercise compliance scale for orthopedic patients,Social Support Rating Scale(SSRS),American Orthopedic Foot and Ankle Score(AOFAS)Ankle-Hindfoot Score,and pain factors[serum bradykinin(BK),prostaglandin E2(PGE2),5-hydroxytryptamine(5-HT)].RESULTS Based on the AOFAS Ankle-Hindfoot Scale,the cases were divided into the excellent function(n=111)and ordinary function(n=39)groups.Univariate analysis revealed that monthly family income,education level,diabetes mellitus,functional exercise compliance scale of orthopedic patients score,SSRS,BK,PGE2,and 5-HT significantly influenced limb function after ankle fracture(P<0.05);Multiple linear regression analysis showed that the functional exercise compliance scale score,SSRS,BK,PGE2,and 5-HT were independent risk factors affecting functional performance after staged functional exercise(P<0.05).CONCLUSION Exercise compliance,SSRS,and pain level are the independent risk factors affecting functional performance after staged functional training following ankle surgery.Clinical nursing care after ankle surgery should include analgesic and health education measures to ensure optimal recovery of limb function.
文摘Introduction and Background: Ankle injury is one of the most frequent presenting injuries to the emergency room and ankle fractures are common fracture in the lower limbs injuries that may require operative treatment with variable outcomes. Materials and Methods: Sixty-three patients were included in my retrospective study, and all with a displaced fracture of the ankle caused by high energy trauma were treated by open reduction and rigid internal fixation. Results: After follow-up at six weeks and twelve weeks, the results were satisfactory in fifty-five percent out of all the sixty-three patients. Conclusions and Recommendations: Ankle fractures occur mainly in young males of the age group between 26 and 35 years, mostly caused by fall down and motor vehicle accident.
文摘Objective:To analyze the value of applying evidence-based nursing in the perioperative care of patients with ankle fractures and propose corresponding measures to improve the quality of patient care.Methods:The study started in May 2022 and was terminated in March 2023.During this period,50 patients with ankle fractures treated by our hospital were selected as research subjects.They were divided into a control group and a research group.The control group had 25 patients who received routine care,and the research group had 25 who received evidence-based care.The nursing effects of the two groups were observed and compared.Results:The pain scores,quality of life,incidence of adverse reactions,and nursing satisfaction of patients in the research group were all significantly better than those in the control group(P<0.05).Conclusion:Evidence-based nursing can effectively improve the quality of care,reduce the risk of adverse reactions,and promote patient recovery,so it is suitable for clinical implementation.
文摘AIM: To report ankle fracture configurations and bone quality following arthroscopic-assisted reduction and internal-fixation(ARIF) or open reduction and internalfixation(ORIF). METHODS: The patients of ARIF(n = 16) or ORIF(n = 29) to treat unstable ankle fracture between 2006 and 2014 were reviewed retrospectively. Baseline data, including age, sex, type of injury, immediate postoperative fracture configuration(assessed on X-rays and graded by widest gap and largest step-off of any intraarticular site), bone quality [assessed with bone mineral density(BMD) testing] and arthritic changes on X-rays following surgical treatments were recorded for each group.RESULTS: Immediate-postoperative fracture configurations did not differ significantly between the ARIF and ORIF groups. There were anatomic alignments as 8(50%) and 8(27.6%) patients in ARIF and ORIF groups(P = 0.539) respectively. There were acceptable alignments as 12(75%) and 17(58.6%) patients in ARIF and ORIF groups(P = 0.341) respectively. The arthritic changes in follow-up period as at least 16 wk following the surgeries were shown as 6(75%) and 10(83.3%) patients in ARIF and ORIF groups(P = 0.300) respectively. Significantly more BMD tests were performed in patients aged > 60 years(P < 0.001), ARIF patients(P = 0.021), and female patients(P = 0.029). There was no significant difference in BMD test t scores between the two groups. CONCLUSION: Ankle fracture configurations following surgeries are similar between ARIF and ORIF groups, suggesting that ARIF is not superior to ORIF in treatment of unstable ankle fractures.
文摘The precise diagnosis of distal tibiofibular syndesmotic ligament injury is challenging and a distinction should be made between syndesmotic ligament disruption and real syndesmotic instability.This article summarizes the available evidence in the light of the author’s opinion.Pre-operative radiographic assessment,standard radiographs,computed tomography scanning and magnetic resonance imaging are of limited value in detecting syndesmotic instability in acute ankle fractures but can be helpful in planning.Intra-operative stress testing,in the sagittal,coronal or exorotation direction,is more reliable in the diagnosis of syndesmotic instability of rotational ankle fractures.The Hook or Cotton test is more reliable than the exorotation stress test.The lateral view is more reliable than the AP mortise view because of the larger displacement in this direction.When the Hook test is used the force should be applied in the sagittal direction.A force of 100 N applied to the fibula seems to be appropriate.In the case of an unstable joint requiring syndesmotic stabilisation,the tibiofibular clear space would exceed 5 mm on the lateral stress test.When the surgeon is able to perform an ankle arthroscopy this technique is useful to detect syndesmotic injury and can guide anatomic reduction of the syndesmosis.Many guidelines formulated in this article are based on biomechanical and cadaveric studies and clinical correlation has to be established.
文摘Ankle fracture is one of the most common lower limb fractures for they account for 9% of all fractures representing a significant portion of the trauma workload. Ankle fractures usually affect young men and older women, however, below the age of 50;ankle fractures are the commonest in men. Two commonly used classification systems for ankle fractures include the danis weber AO classification and the Lauge-Hansen classification. There is biomechanical evidence that posterior non-locking plates are superior in stability than laterally placed plates;however there is little clinical evidence. There are several different methods of ankle fracture fixation, however the goal of treatment remains a stable anatomic reduction of talus in the ankle mortise and correction of the fibula length as a 1 mm lateral shift of the talus in the ankle mortise reduces the contact area by 42%, and displacement (or shortening) of the fibula more than 2 mm will lead to significant increases in joint contact pressures. Further research both biomechanically and clinically needs to be undertaken in order to clarify a preferable choice of fixation.
文摘A stable and precise articulation of the distal tibiofibular syndesmosis maintains the tibiofibular relationship,and it is essential for normal motion of the ankle joint.The disruption of this joint is frequently accompanied by rotational ankle fracture,such as pronation-external rotation,and rarely occurs without ankle fracture.The diagnosis is not simple,and ideal management of the various presentations of syndesmotic injury remains controversial to this day.Anatomical restoration and stabilization of the disrupted tibiofibular syndesmosis is essential to improve functional outcomes.In such an injury,including inadequately treated,misdiagnosed and correctly diagnosed cases,a chronic pattern characterized by persistent ankle pain,function disability and early osteoarthritis can result.This paper reviews anatomical and biomechanical characteristics of this syndesmosis,the mechanism of its acute injury associated to fractures,radiological and arthroscopic diagnosis and surgical treatment.
文摘Ankle fractures are one of the most common injuries treated by orthopaedic surgeons. A minority of patients with ankle fractures go on to develop persistent pain following anatomical reduction. These sequelae may arise as a result of untreated ligamentous or chondral injuries. This study aims to correlate acute arthroscopic ankle findings with the <i><span>Lauge-Hansen </span></i><span>fracture pattern classification. We further aim to compare subjective functional outcomes at least one year following surgery between patients who have received Open Reduction and Internal Fixation (ORIF) alone, </span><b><i><span>versus</span></i></b><i><span> </span></i><span>ORIF </span><i><span>plus</span></i><span> arthroscopy.

文摘Purpose: To measure the effectiveness of using percutaneous intramedullary screw fixation of the lateral malleolus fracture on the healing and functional outcome of ankle fracture. Materials and methods: Forty-six patients with Weber A and low Weber B displaced lateral malleolus fractures who underwent closed reduction and percutaneous internal fixation with an intramedullary, fully threaded, screw were retrospectively reviewed. A 3.5-mm, fully threaded, selftapping bone screw (stainless steel from Pelvic Set Synthes). The length of the screw varies between 100 mm and 120 mm, depending on the fracture location and pattern. Results: All fractures united within an average time to union of 8.2 weeks. In all patients the average time to full weight bearing was 6.8 weeks, whereas that in patients with isolated lateral malleolus fractures was 4.5 weeks. There were no deep wound infections or complaints of painful hardware. At latest follow-up, functional results were excellent in, 25 patients (54.3%) good in 20 (43.5%), fair in (2.2%). Conclusion: If reduction of the lateral malleolus fracture can be obtained in a closed fashion (with the aid of an image x-ray intensifier), we believe that fixation may be performed with an axial screw percutaneously. This technique is quick, safe and easy to do with less complication.
文摘BACKGROUND Locking plate fixation in osteoporotic ankle fractures may fail due to cut-out or metalwork failure.Fibula pro-tibia fixation was a technique prior to the advent of locking plates that was used to enhance stability in ankle fractures by achieving tri or tetra-cortical fixation.With locking plates,the strength of this fixation construct can be further enhanced.There is lack of evidence currently on the merits of tibiapro-fibula augmented locking plate fixation of unstable ankle fractures.AIM To assess if there is increased strength to failure,in an ankle fracture saw bone model,with a fibula pro-tibia construct when compared with standard locking plate fixation.METHODS Ten osteoporotic saw bones with simulated supination external rotation injuries were used.Five saw bones were fixed with standard locking plates whilst the other 5 saw bones were fixed with locking plates in a fibula pro-tibia construct.The fibula pro-tibia construct involved fixation with 3 consecutive locking screws applied across 3 cortices proximally from the level of the syndesmosis.All fixations were tested in axial external rotation to failure on an electromagnetic test frame(MTS 858 Mini-Bionix test machine,MTS Corp,Eden Praire,MN,United States).Torque at 30 degrees external rotation,failure torque,and external rotation angle at failure were compared between both groups and statistically analyzed.RESULTS The fibula pro-tibia construct demonstrated a statistically higher torque at 30 degrees external rotation(4.421±0.796 N/m vs 1.451±0.467 N/m;t-test P=0.000),as well as maximum torque at failure(5.079±0.694N/m vs 2.299±0.931 N/m;t-test P=0.001)compared to the standard locking plate construct.The fibula pro-tibia construct also had a lower external rotation angle at failure(54.7±14.5 vs 67.7±22.9).CONCLUSION The fibula pro-tibia locking plate construct demonstrates biomechanical superiority to standard locking plates in fixation of unstable ankle fractures in this saw bone model.There is merit in the use of this construct in patients with unstable osteoporotic ankle fractures as it may aid improved clinical outcomes.
文摘Introduction: Neglected ankle fractures are common in our regions. Patients first consult traditional healers and it is when the signs persist that they consult the surgeon for a swollen and painful ankle. Initially we always performed anatomical repairs with osteosynthesis, but the majority of patients still complained of pain and disability. We wondered whether a primary arthrodesis would not be indicated in old ankle fractures to avoid disabling pain for patients. We therefore performed a series of arthrodesis on neglected post-traumatic ankles. The objective of our study was to describe the results of arthrodesis on an old post-traumatic ankle and to propose a therapeutic indication in the face of any neglected ankle fracture. Material and Method: This was a prospective study over 8 years between December 2012 and November 2020, involving 36 cases of neglected ankle fractures treated by arthrodesis using Meary’s technique. We used AOFAS (American Orthopedic Foot and Ankle Score) preoperatively and postoperatively for an objective assessment. Results: The average follow-up was 4.2 years and our results were satisfactory (94.4%) with an average AOFAS score ranging from 27.8 preoperatively to 76.7 postoperatively. The fusion rate was 97.2%. Discussion: Arthrodesis appears here as an important alternative in the treatment of neglected ankle fractures with significant trophic disorders.

文摘Obesity is a growing problem defined as a body mass index of greater than 30 kg/m2.It is predicted that by 2030,48.9%of adults will be classified as obese which expands surgical risk factors to a broad population while increasing healthcare costs at the same time in different socioeconomic groups.This specific population has been widely studied in multiple surgical fields and published studies have shown the implications in each of these fields.The impact of obesity on orthopedic surgical outcomes has been previously reported in several total hip and knee arthroscopy studies,with evidence indicating that obesity is strongly associated with an increased risk of post operative complications together with higher revision rates.In line with increasing interest on the impact of obesity in orthopedics,there has been a similar output of publications in the foot and ankle literature.This review article evaluates several foot and ankle pathologies,their risk factors associated with obesity and subsequent management.It provides an updated,comprehensive analysis of the effects of obesity on foot and ankle surgical outcomes,with the ultimate aim of educating both surgeons and allied health professionals about the risks,benefits,and modifiable factors of operating on obese patients.
文摘BACKGROUND Ankle fractures are common injuries in the young and elderly populations.To prevent post-traumatic arthritis,an anatomic reconstruction of the ankle structure is mandatory.Open reduction and internal fixation is the treatment of choice among orthopaedics.Conventional plates allow stability of the fracture if bone quality is present.Locking plates might offer an advantage for the treatment of lateral malleolar fracture in patients with comminution,severe instability,distal fractures,or osteoporotic bone.Our hospital introduced a new locking plate for fracture of the distal fibula.AIM To evaluate locking plates in terms of outcomes and complications in young and elderly patients.METHODS We retrospectively reviewed a total of 67 patients treated for displaced distal fibula fractures.Demographic data,number of comorbidities,use of inter fragmentary screw,complication,time of fracture healing,partial or full weight bearing,and reoperation were recorded for all patients.Clinical outcome was assessed by the American Orthopedic Foot and Ankle Society clinical scoring system.Radiographs were obtained at 4,8,12,16,20,and 24 wk until radiographic union was obtained.RESULTS All patients displayed complete bony union on radiographic assessment,and no patients developed any serious complications.We observed two superficial infections,one delayed wound healing,and two plate intolerances.Significant differences were observed between the two age groups in terms of radiographic healing(11.9 wk in younger patients vs 13.7 wk in older patients;P=0.011)and in the American Orthopedic Foot and Ankle Society score at 6 mo after surgery(88.2 in younger patients vs 86.0 in older patients;P=0.001)and at 12 mo after surgery(92.6 in younger patients vs 90.0 in older patients;P=0.000).CONCLUSION Locking plates provide a stable and rigid fixation in multifragmentary and comminuted fractures or in the presence of poor bone quality.
文摘BACKGROUND Ankle fractures are common lesions of the lower limbs.Approximately 40%of ankle fractures affect the posterior malleolus(PM).Historically,PM osteosynthesis was recommended when PM size in X-ray images was greater than 25%of the joint.Currently,computed tomography(CT)has been gaining traction in the preoperative evaluation of ankle fractures.AIM To elucidate the similarity in dimensions and to correlate PM size in X-ray images with the articular surface of the affected tibial plafond in the axial view on CT(AXCT)of a PM fracture.METHODS Eighty-one patients(mean age:39.4±13.5 years)were evaluated(54.3%were male).Two independent examiners measured PM size in profile X-ray images(PMXR)and sagittal CT(SAGCT)slices.The correlation of the measurements between the examiners and the difference in the PM fragment sizes between the two images were compared.Next,the PM size in PMXR was compared with the surface of the tibial plafond involved in the fracture in AXCT according to the Haraguchi classification.RESULTS The correlation rates between the examiners were 0.93 and 0.94 for PMXR and SAGCT,respectively(P<0.001).Fragments were 2.12%larger in SAGCT than in PMXR(P=0.018).In PMXR,there were 56 cases<25%and 25 cases≥25%.When PMXR was<25%,AXCT corresponded to 10.13%of the tibial plafond.When PMXR was≥25%,AXCT was 24.52%(P<0.001).According to the Haraguchi classification,fracture types I and II had similar PMXR measurements that were greater than those of type III.When analyzing AXCT,a significant difference was found between the three types,with II>I>III(P<0.001).CONCLUSION PM fractures show different sizes using X-ray or CT images.CT showed a larger PM in the sagittal plane and allowed the visualization of the real dimensions of the tibial plafond surface.
文摘Fractures of the talus are rare in children.A high index of suspicion is needed to avoid missing such an injury,which is not an uncommon occurrence especially with undisplaced fractures.We present an unusual case of an undisplaced talar neck fracture in a five-year-old child leading to a delayed presentation of a symptomatic osteochondral loose body in the ankle joint.To our knowledge there are no reports in the literature of osteochondral loose bodies occurring in conjunction with an associated undisplaced talar neck fracture in either children or adults.The loose body was removed using anterior ankle arthroscopy.The child had an uneventful post operative recovery and regained full range of movement and function of his ankle joint and was discharged at one year follow-up.We aim to highlight the need to have a low threshold to further evaluate symptomatic children after fracture healing of an undisplaced talar neck fracture for a possible associated loose bodyin the ankle joint.

文摘BACKGROUND Posterior malleolar fractures have been reported to occur in<40%of ankle fractures.AIM To reveal the recurrent patterns and characteristics of posterior malleolar fractures by creating fracture maps of the posterior malleolar fractures through the use of computed tomography mapping.METHODS A consecutive series of posterior malleolar fractures was used to create threedimensional reconstruction images,which were oriented and superimposed to fit an ankle model template by both aligning specific biolandmarks and reducing reconstructed fracture fragments.Fracture lines were found and traced in order to generate an ankle fracture map.RESULTS This study involved 112 patients with a mean age of 49,comprising 32 pronationexternal rotation grade IV fractures and 80 supination-external rotation grade IV fractures according to the Lauge-Hansen classification system.Three-dimensional maps showed that the posterior ankle fracture fragments in the supinationexternal rotation grade IV group were relatively smaller than those in the pronation-external rotation grade IV group after posterior malleolus fracture.In addition,the distribution analyses on posterior malleolus fracture lines indicated that the supination-external rotation grade IV group tended to have higher linear density but more concentrated and orderly distribution fractures compared to the pronation-external rotation grade IV group.CONCLUSION Fracture maps revealed the fracture characteristics and recurrent patterns of posterior malleolar fractures,which might help to improve the understanding of ankle fracture as well as increase opportunities for follow-up research and aid clinical decision-making.
文摘Posterior malleolus fractures are quite common and usually result from rotational ankle injuries. For the management of posterior malleolus fractures, more studies are still required, though it is already well-recognized for medial and lateral structure. Therefore, fracture of posterior malleolus is striking subject of study among orthopedic surgeons. Most orthopedic surgeons recommend fixing the posterior malleolus fracture if it is larger than 25% to 33% of the distal articular surface. Further attention is required for the reduction and fixation of fractures involving posterior malleolus. Several approaches and methods for fixation of posterior malleolus have been defined in the literature. Previously, the most common method of fixation of the posterior malleolus is by indirect reduction and antero-posterior screws, it is minimally invasive, the anterior incision does not allow satisfactory visualization of the fragment, so good anatomical reduction is difficult to achieve thorough this approach. Operative management goals to reach a stable ankle with maximal function, decrease the risk of post-traumatic degenerative changes, and diminish the risk of complication. Nowadays, posterolateral approach is gaining the popularity due to adequate visualization and accurate anatomic reduction.
