ABSTRACT
Patient-reported outcomes (PROs) are information that comes directly from any aspect of a patient's own health status. The traditional patient-reported outcome measures (PROMs) used in foot and ankle surgery include the American Association of Foot and Ankle Surgery series scale, the visual analogue scale, the medical outcomes study 36-item short form of health survey (SF-36), the foot and ankle outcome scale and the medical outcome study 12-item short form of health survey (SF-12). In the process of use, these PROMs can not accurately reflect the patient's feelings because of the subjective influence of doctors, only responding to specific diseases or general health conditions, and the test fatigue caused by too long questionnaires, which ultimately affect the reliability and validity of the results. The scales of the patient-reported outcome measurement information system (PROMIS) led by National Institutes of Health have been verified to have good reliability, validity and responsiveness, and its results are true and reliable, and have high clinical reference significance. The PROMIS includes short forms, short form collection and computerized adaptive test (CAT), of which the PROMIS CAT is built on scientific item response theory, with the selection of each question highly correlated with the underlying trait of the patient, and the accuracy and credibility of PROs significantly improved. The PROMIS score has been applied in clinical practice in foot and ankle surgery (including hallux valgus, flatfoot and talar neck fractures, etc.) and has demonstrated excellent and stable preoperative prediction and prognosis evaluation ability. The presentation of PROMIS and its application progress can enhance the participation of patients of foot and ankle surgery in medical activities and guide clinical decision-making in foot and ankle surgery.
ABSTRACT
Osteochondral lesion of talus (OLT) is a foot and ankle disease characterized by ankle pain, which may impact the joint function and life quality. If managed improperly, it may lead to a further ankle arthritis, severely compromising the prognosis. The therapeutic effect of conservative treatment for OLT is still uncertain. Surgery is still the main treatment modality for OLT with various techniques. However, the optimized surgical technique is still inconclusive, furthermore, regeneration and repair of cartilage after debridement is also a great challenge for the treatment of OLT. Platelet-rich plasma (PRP) with good repair effect on cartilage injury is gradually applied in the treatment of OLT. However, there still lacks the unified understanding of the technique and specification of PRP for the treatment of OLT. Therefore, National Orthopedics Center of Shanghai Sixth People′s Hospital allied Foot Ankle Basic Research & Orthopedics Group, Chinese Association of Orthopedic Surgeons; Foot and Ankle Committee of Chinese Association of Sports Medicine Physicians; and Foot and Ankle Group of Orthopedic Specialized Branch of Shanghai Medical Association to organize related experts to formulate the Expert consensus on platelet- rich plasma treatment for osteochondral lesion of talus ( version2023). Fifteen recommendations were put forward upon PRP preparation, indications, contraindications and treatment methods of PRP for OLT, so as to standardize the PRP treatment for OLT.
ABSTRACT
Periarticular fracture of the shoulder is a common type of fractures in the elderly. Postoperative adverse events such as internal fixation failure, humeral head ischemic necrosis and upper limb dysfunction occur frequently, which seriously endangers the exercise and health of the elderly. Compared with the fracture with normal bone mass, the osteoporotic periarticular fracture of the shoulder is complicated with slow healing and poor rehabilitation, so the clinical management becomes more difficult. At present, there is no targeted guideline or consensus for this type of fracture in China. In such context, experts from Youth Osteoporosis Group of Chinese Orthopedic Association, Orthopedic Expert Committee of Geriatrics Branch of Chinese Association of Gerontology and Geriatrics, Osteoporosis Group of Youth Committee of Chinese Association of Orthopedic Surgeons and Osteoporosis Committee of Shanghai Association of Chinese Integrative Medicine developed the Chinese expert consensus on the diagnosis and treatment of osteoporotic periarticular fracture of the shoulder in the elderly ( version 2023). Nine recommendations were put forward from the aspects of diagnosis, treatment strategies and rehabilitation of osteoporotic periarticular fracture of the shoulder, hoping to promote the standardized, systematic and personalized diagnosis and treatment concept and improve functional outcomes and quality of life in elderly patients with osteoporotic periarticular fracture of the shoulder.
ABSTRACT
Objective:To investigate the change of syndesmotic volume via CT scan in Danis-Weber B type ankle fracture, aiming to provide a non-invasive diagnostic method for Danis-Weber B type ankle fracture combined with syndesmotic injury.Methods:Retrospective analysis was performed on 48 patients with Danis-Weber B type ankle fractures in Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2018 to March 2022, including 30 males and 18 females, aging (43.71±19.41) years. Ankle CT scans and three-dimensional reconstructions were performed before surgery and at the last follow-up, measuring the syndesmotic volume between the tibiotalar joint and 1, 3 and 5 cm above the ankle and compared with each other. Intraoperative exploration was used as the gold standard for the syndesmotic injury. Based on the results of exploration of the syndesmotic injury, patients were divided into simple ankle fracture group (fracture group, 25 cases) and ankle fracture combined with syndesmotic injury group (fracture + ligament group, 23 cases). The sensitivity and specificity of this diagnostic method were statistically evaluated. The assessments at the last follow-up were performed to value the clinical effect of surgery. The metric data conforming to the normal distribution were expressed as mean ± standard deviation ( ± s), and the t-tests were used for comparison between groups. The measurement data of skewed distribution were expressed as quartile M( Q1, Q3), and nonparametric tests were used for intergroup comparison. Counting data were expressed as number of cases and percentage (%), and Chi-square test were used for intergroup comparison. Results:In the fracture group, there were no statistically significant differences of the syndesmotic volume at 1, 3, and 5 cm above the ankle joint before surgery and at the last follow-up ( P=0.219, 0.269, 0.103). On the contrary, the volume above were statistically significant in the fracture + ligament group ( P<0.001). There were statistically significant differences in syndesmotic volume between the two groups at 1, 3, and 5 cm above the ankle joint preoperatively ( P=0.005, 0.004, 0.038). By contrast, there were no statistical differences between the two groups postoperatively ( P=0.082, 0.155, 0.249). For the sensitivity and specificity of Danis-Weber B type ankle fractures combined with syndesmotic injury, they were 92% and 67% at 1 cm above the ankle joint, 69% and 87% at 3 cm above the ankle joint, and 62% and 87% at 5 cm above the ankle joint, respectively. The last follow-up clinical function score indicated a good surgical outcome. Conclusions:Volumetric measurement via CT scan is one of the diagnostic methods for evaluating Danis-Weber B type ankle fracture combined with syndesmotic injurys. Open resection internal fixation combined with elastic fixation of the ankle fracture combined with syndesmotic injurys can significantly reduce the lower tibiofibular volume, and the efficacy is definite.
ABSTRACT
Objective:To investigate the efficacy of osteochondral fragment fixation using bioabsorbable pins for Hepple Ⅱ osteochondral lesions of the talus (OLT) in adolescents.Methods:Retrospective case analysis was used. The clinical data and follow-up results of 13 adolescent patients (13 feet) with Hepple Ⅱ OLT were all treated with osteochondral fragment fixation using bioabsorbable pins admitted to Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2017 to December 2021 were retrospectively analyzed. There were 7 males and 6 females, with 13 right feet. The age was (14.85±2.23) years old, ranged from 12 to 18 years old. According to the American orthopedic foot and ankle society (AOFAS) ankle-hindfoot score, visual analogue scale (VAS) and SF-36 score before operation and at the last follow-up were used to evaluate the efficacy and function of the patients. Measurement data with normal distribution were represented as mean ± standard deviation( ± s), and the comparison between groups was conducted using the t-test; The mearsurement data with skewness distribution were expressed by M( Q1, Q3), and rank-sum test was used for inter-group comparison. Results:Thirteen adolescent patients (13 feet) with Hepple Ⅱ OLT underwent surgery successfully and were followed up for (25.54±9.95) months. All wounds healed by first intention, and no complications such as wound infection and delayed healing occurred. Preoperative AOFAS ankle-posterior foot score, VAS and SF-36 score were 58.62±3.55, 7.00 (6.50, 8.00) and 68.38±4.81, respectively. At the last follow-up, the scores were 97.38±2.73, 1.00 (0.00, 1.00), 91.15±4.28, respectively, and the results were significantly improved at the last follow-up, with the difference between the two groups statistically significant( P<0.05). Conclusion:Osteochondral fragment fixation using bioabsorbable pins which can promote cartilage repair, significantly improve symptoms, and achieve better clinical satisfaction with fewer complications, is a safe and effective surgical treatment option for Hepple Ⅱ OLT in adolescents with satisfactory short-term clinical outcomes.
ABSTRACT
Objective:To study the morphology of dorsal medial talar neck osteophyte (DMTNO) and its association with anteromedial ankle impingement syndrome (AAIS) using CT 3D reconstruction images.Methods:The present retrospective study included 23 patients with AAIS due to DMTNO (case group) and 23 patients with DMTNO but without AAIS (control group) who had been admitted from February 2019 to June 2021. Multi-slice CT data (DICOM) of DMTNO in both groups were collected and imported into Arigin 3D Pro 3D reconstruction software to reconstruct and observe the 3D morphology of DMTNO. The dorsal convex distance, medial convex distance and anterior convex distance of DMTNO were measured to find their association with AAIS.Results:In the case group, DMTNO clearly showed a flat polyhedral shape with a large base and a small top; in the control group, DMTNO showed various shapes that were different mainly in an irregular top but similar in a large, long and narrow base. The dorsal convex distance [(8.07±2.30) mm] and medial convex distance [(6.70±2.62) mm] in the case group were significantly larger than those in the control group [(3.59±1.10) mm and (1.98±0.93) mm] ( P<0.05), but there was no significant difference between the 2 groups in the anterior convex distance ( P>0.05). Conclusions:The DMTNO leading to AAIS shows a flat polyhedral shape with a large base and a small top. No correlation is found between the anterior convex and AAIS whereas the dorsal convex and medial convex of DMTNO may be closely associated with AAIS.
ABSTRACT
Objective:To evaluate the mid-term efficacy of surgery for sub-acute injury to distal tibiofibular syndesmosis associated with ankle fracture.Methods:From July 2014 to October 2019, 14 patients were treated at Foot & Ankle Section, Department of Orthopaedics, Shanghai Sixth People’s Hospital for sub-acute injury to distal tibiofibular syndesmosis associated with ankle fracture.There were 11 males and 3 females, aged from 17 to 61 years (mean, 35.9 years).According to Danis-Weber classification, 6 cases were type B and 8 type C; according to Lauge-Hansen classification, 7 cases belonged to supination-external rotation, one to pronation-abduction, and 6 to pronation-external rotation (Maisonneuve fracture in 4).The syndesmosis injury was treated by fixation with distal tibiofibular screws in 11 cases, by Tightrope elastic fixation in one, by hybrid fixation with distal tibiofibular screws and Tightrope in one, and by distal tibiofibular fusion in one.Postoperative complications were recorded.Their visual analogue scale (VAS) and American Orthopaedic Foot and Ankle Society ankle-hindfoot scores (AOFAS-AH) were compared between preoperation and the last follow-up.Results:The 14 patients were followed up for 24 to 85 months (mean, 46.8 months). Of the 9 patients whose distal tibiofibular screws had been removed (including one with hybrid fixation), wound infection occurred in one after removal of all the internal fixation, distal tibiofibular widening in 2, ankle degeneration in 5 and fibular nonunion in one. Of the other 3 patients whose distal tibiofibular screws had not been removed, screw breakage happened in 2, screw loosening in one and distal tibiofibular widening in one. The VAS scores were significantly improved from preoperative 6.8±0.9 to 1.4±1.3 at the last follow-up; the AOFAS-AH scores were increased significantly from preoperative 35.3±6.3 to 86.8±11.7 at the last follow-up (both P<0.001). According to AOFAS-AH scores, 8 cases were excellent, 4 good and 2 moderate. Conclusion:Surgery for sub-acute injury to distal tibiofibular syndesmosis associated with ankle fracture can restabilize the distal tibiofibular syndesmosis and ankle joint, reduce pain and improve ankle function, leading to fine mid-term efficacy.
ABSTRACT
Lower extremity deep vein thrombosis (DVT) is one of the main complications in patients with traumatic fractures, and for severe patients, the DVT can even affect arterial blood supply, resulting in insufficient limb blood supply. If the thrombus breaks off, pulmonary embolism may occur, with a high mortality. The treatment and rehabilitation strategies of thrombosis in patients with lower extremity fractures have its particularity. DVT in traumatic fractures patients has attracted extensive attention and been largely studied, and the measures for prevention and treatment of DVT are constantly developing. In recent years, a series of thrombosis prevention and treatment guidelines have been updated at home and abroad, but there are still many doubts about the prevention and treatment of DVT in patients with different traumatic fractures. Accordingly, on the basis of summarizing the latest evidence-based medical evidence at home and abroad and the clinical experience of the majority of experts, the authors summarize the clinical treatment and prevention protocols for DVT in patients with traumatic fractures, and make this consensus on the examination and assessment, treatment, prevention and preventive measures for DVT in patients with different fractures so as to provide a practicable approach suitable for China ′s national conditions and improve the prognosis and the life quality of patients.
ABSTRACT
Flatfoot is a deformity related to the collapse of the medial arch of the foot, heel valgus and forefoot abduction. The etiology and treatment plan are affected by many factors. Conservative treatment can be given in the early stage. When conservative treatment reaches a certain time and fails to improve symptoms, surgical treatment is required. Among them, HyproCure subtalar stabilization is a new minimally invasive surgical method, which has been popularized in recent years. It has remarkable effect in correcting deformities. Because the morphological design of HyproCure is more suitable for the tarsal sinus, it can enable the subtalar joint to carry out normal three-dimensional activities without excessive correction or restriction of foot movement. Compared with the traditional surgical method, it has the advantages of small incision It has the characteristics of simple operation and less postoperative complications, and can partially replace calcaneal osteotomy. By reviewing the recently published literature, this paper reviews the advantages of subtalar stabilization and the limitations compared with traditional surgery.
ABSTRACT
Ankle fracture is caused by direct or indirect violence to the integrity and continuity of the distal tibia and/or fibula, often associated with ligament and other soft tissue injuries. However, ankle fracture can be easily overlooked during diagnosis and treatment due to hidden injuries or lack of experience, often resulting in poor prognosis. The existing classifications are sometimes difficult to provide guidances for clinical decision making, so the classification of ankle fracture based on stability criteria comes into being. Improper management of unstable ankle fracture can lead to serious complications such as loss of function and traumatic arthritis, requiring individualized treatment based on the specific injury. The authors review the concept, anatomy and imageological evaluation of ankle fracture stability as well as its treatment based on stability classification, so as to provide new ideas for the stability evaluation and treatment of ankle fracture.
ABSTRACT
Lateral ankle avulsion fracture is a common sports injury that can lead to chronic lateral ankle instability and substantial deterioration of the joint function. Currently, problems such as misdiagnosis, inappropriate treatment, disparate outcomes and lack of standardization are usually met in the diagnosis and treatment of lateral ankle avulsion fracture. The Foot and Ankle Committee of Chinese Association of Sports Medicine Physicians thus organized a working group of experts in the field of sports medicine and ankle surgery from China to develop "An evidence-based clinical guideline for the diagnosis and treatment of lateral ankle avulsion fractures (2022 version)" in accordance with the principle of evidence-based medicine and scientificity and practicability. The guideline covered the topics of imaging diagnosis, indications and methods of non-operative and operative treatment as well as postoperative rehabilitation, in order to provide guidance for the diagnosis and treatment of lateral ankle avulsion fracture.
ABSTRACT
Objective:To investigate the efficacy of posterior ankle arthroscopic microfracture with platelet-rich plasma (PRP) injection for the treatment of posterior osteochondral lesions of the talus (OLT).Methods:A retrospective case series study was conducted on clinical data of 13 patients with posterior OLT admitted to Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University from September 2019 to October 2020. There were 10 males and 3 females, aged 10-65 years [(38.2±15.9)years]. According to Hepple′s classification, four patients were with type II, three with type IV, and six with type V. According to Elias′ grid scheme, nine patients were in zone 7 and four patients in zone 9. The disease duration was 13-51 months [(26.2±11.4)months]. All patients underwent posterior ankle arthroscopic microfracture with PRP injection. The operation time was recorded. The visual analogue scale (VAS), American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score, and ankle range of motion (ROM) were compared before operation and at 3 months and 1 year after operation. The magnetic resonance observation of cartilage repair tissue (MOCART) score was used to evaluate the repair of cartilage injury at 1 year after operation. Complications were recorded.Results:All patients were followed up for 12-25 months [(15.7±3.7)months]. The operation time ranged from 50 to 90 minutes [(63.8±13.3)minutes]. The VAS improved from 3.0(3.0, 4.0)points before operation to 1.0(0, 2.0)points at 3 months after operation and 1.0(0,1.5)points at 1 year after operation; the AOFAS ankle-hindfoot score was improved from (66.1±11.8)points before operation to (84.8±9.5)points at 3 months after operation and (92.9±8.6)points at 1 year after operation; the ankle ROM was improved from (48.5±7.5)° before operation to (61.9±10.3)° at 3 months after operation and (65.4±11.8)° at 1 year after operation (all P<0.05). There was no significant difference in VAS at 3 months and 1 year after operation ( P>0.05). There were significant differences in AOFAS ankle-hindfoot score and ankle ROM at 3 months and 1 year after operation (all P<0.05). According to AOFAS ankle-hindfoot score, the results were excellent in 11 patients, good in one, and fair in one, with the excellent and good rate of 92%. The MOCART score was 40-85 points [(70.4±14.2)points] at 1 year after operation. There was no postoperative necrosis, infection or neurovascular injury. Two patients had slight transient pain during rehabilitation training and were improved after non-surgical treatment. Conclusion:For posterior OLT, posterior ankle arthroscopic microfracture with PRP injection can effectively alleviate pain, improve ankle function and repair cartilage damage, with satisfactory short-term efficacy.
ABSTRACT
Objective:To evaluate the short-term outcome of arthroscopic modified Brostr?m procedure plus minimally invasive calcaneal osteotomy for the treatment of chronic lateral ankle instability combined with subtle cavus foot.Methods:A retrospective cohort study was conducted to analyze the clinical data of 12 patients suffering chronic lateral ankle instability combined with subtle cavus foot admitted to Shanghai Sixth People′s Hospital Affiliated to Shanghai Jiao Tong University from November 2016 to November 2020, including 5 males and 7 females, aged 16-62 years [(40.3±15.1)years]. All patients were treated with arthroscopic modified Brostr?m procedure plus minimally invasive calcaneal osteotomy. The calcaneal pitch angle, Meary′s angle and medial cuneiform height on the foot weight-bearing lateral view plus calcaneus valgus angle on the hindfoot long axial view were compared to evaluate the improvement of bony structure and foot alignment preoperatively and at 3 months and 1 year postoperatively. At the same time, American Orthopedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and visual analogue scale (VAS) were used to evaluate the improvement of ankle function and pain. Postoperative complications were also observed and recorded.Results:All patients were followed up for 1-3 years [(1.6±0.6)years]. The calcaneal pitch angle was decreased from (24.6±5.3)° preoperatively to (22.5±4.9)° at postoperative 3 months and (22.3±5.0)° at postoperative 1 year; the Meary′s angle was decreased from 6.6°(5.2°,7.6°) preoperatively to 2.5°(0.5°,3.8°) at postoperative 3 months and 2.1°(0.5°,3.2°) at postoperative 1 year; the medial cuneiform height was decreased from (24.3±5.3)mm preoperatively to (22.3±4.8)mm at postoperative 3 months and (22.3±4.6)mm at postoperative 1 year; the calcaneus valgus angle was increased from -7.1°(-10.3°,-5.9°) preoperatively to 2.3°(-2.5°,4.5°) at postoperative 3 months and 2.4°(-1.6°,3.8°) at postoperative 1 year (all P<0.01). However, there were no significant differences in the calcaneal pitch angle, Meary′s angle, medial cuneiform height, and calcaneus valgus angle at postoperative 3 months and 1 year (all P>0.05). AOFAS ankle-hindfoot score was increased from (66.8±8.7)points preoperatively to (81.0±5.9)points at postoperative 3 months and (88.6±3.6)points at postoperative 1 year (all P<0.01). According to AOFAS ankle-hindfoot score, the results were excellent in four patients and good in eight patients at postoperative 1 year, with the excellent and good rate of 100%. VAS was decreased from 2.5(2.0,4.0)points preoperatively to 2.0(1.3,2.8)points at postoperative 3 months and 1.0(0,2.0)points at postoperative 1 year (all P<0.01). There were significant differences in the AOFAS ankle-hindfoot score and VAS at postoperative 3 months and 1 year (all P<0.05). Wound malunion was seen in one patient, and healed with a dress changing. All patients had no complications such as vascular or nerve injury. There was no recurrence of malformation or joint instability during 1-year follow-up. Conclusion:For chronic lateral ankle instability combined with subtle cavus foot, arthroscopic modified Brostr?m procedure plus minimally invasive calcaneal osteotomy can stabilize ankle joint, correct hindfoot alignment, improve function and relieve pain.
ABSTRACT
Acute athletic injuries of foot and ankle may involve bony structures, ligaments and tendons, and most patients manifest as various degrees of swelling, pain and limited motion. Lacking of specificity, the injuries can be easily overlooked by the patients and even by the doctors. Furthermore, the diagnosis can not be confirmed in a portion of the injuries via a routine radiographic examination due to their obscurity, leading to a certain rate of tmiss diagnosis and misdiagnosis, which can be clarified by a detailed specialized physical and radiographic examination. For acute athletic injuries of foot and ankle, the miss diagnosis or misdiagnosis may lead to complications such as chronic joint instability, osteochondral lesion, impingement, and even post-traumatic arthritis, which severely impacts the patients′ life quality. Therefore, the authors discuss the issues requiring attention in the diagnosis and management of acute athletic injuries of foot and ankle to improve the clinical outcome of such pattern of injuries.

ABSTRACT
Ankle osteoarthritis is a degenerative change caused by the destruction of articular cartilage, and it is not difficult to obtain a preliminary clinical diagnosis. However, imaging evaluation is always needed to evaluate the alignment of lower limbs, potential deformity and prognosis. Therefore, it is particularly important to select the right imaging examination to determine the range of joint inflammation, the degree of deformity and the stage of the disease. This paper discusses the imaging examination and clinical correlation of ankle osteoarthritis at home and abroad, in order to summarize the latest clinical experience for the diagnosis and evaluation of ankle osteoarthritis.
ABSTRACT
Chronic syndesmosis injury is of great difficulty in foot and ankle trauma with a high post-traumtaic arthritis morbidity, deformity and disability rate, which is always caused by a delayed management or improper initial surgical treatment, and need an active intervention. Currently, various of treatment technique for chronic syndesmosis injury has been described, however, the optimal strategy should be determined by patient′s classification, symptoms, activity demands and severity of arthritis to maximally relieve the symptoms, preserve functions and improve the life quality. This article will overview the diagnosis and management of chronic syndesmosis injury in this article.
ABSTRACT
Patients with subtle syndesmotic injury, without fracture, have the symptoms similar to lateral ankle ligament injury, thus, leading to diagnostic error and misdiagnosis. Improper treatment often causes chronic pain and dysfunction, accelerating ankle degeneration. The diagnosis of subtle syndesmotic injury demands synthesis of examination results, among which arthroscopy is the gold standard. The treatment of subtle syndesmotic injury depends on the course of injury: conservative treatment, syndesmosis screw, button plate, elastic syndesmosis hook plate and mixed fixation are performed in acute injury. Arthroscopic debridement, syndesmosis fusion and ligament reconstruction are performed in chronic ones. In subacute ones, treatment is controversial. Early diagnosis and treatment of subtle syndesmotic injury play an important role in its prognosis. This article will review the recent advancements in diagnostics and treatment of subtle syndesmotic injury.

ABSTRACT
Objective:To evaluate the clinical results of reduction and fixation via fibular osteotomy for treatment of old ankle fractures involving the posterior malleolus in middle-aged and elderly patients.Methods:A retrospective case series study was made for 13 middle-aged and elderly patients with old ankle fractures involving the posterior malleolus treated from July 2013 to March 2018 in Sixth People's Hospital Affiliated to Shanghai Jiao Tong University. There were 2 males and 11 females, with age of 48-63 years (mean, 54.8 years). The mean surgical period was 8-18 weeks from injury (mean, 9.6 weeks). According to Haraguchi classification, all posterior malleolar fractures were type I. According to Lauge-Hansen classification, there were 2 patients with pronation-external rotation type and 11 with supination-external rotation type. All patients underwent open reduction and fixation via fibular osteotomy. Bone healing time and postoperative complications were recorded. Clinical results were assessed by visual analogue scale (VAS) score and American orthopedic foot and ankle society (AOFAS) ankle-hind score.Results:All patients were followed up for average 20.3 months (range, 9-36 months). All patients had bone union, with the mean healing period of 12-15 weeks (average 14.8 weeks). No infection, implant loosening or breakage occurred after operation. X-ray film of one patient suggested mild traumatic arthritis. At the latest follow-up, VAS was improved to (1.0±0.2)points compared to pre-operative (5.3±0.6)points ( P<0.05), and the AOFAS ankle-hind score was improved to (85.2±7.4)points compared to pre-operative (42.4±6.7)points ( P<0.05). According to the AOFAS ankle-hind score, the results were excellent in 4 patients, good in 8, moderate in 1, with the excellent and good rate of 92%. Conclusion:For old ankle fractures involving the posterior malleolus in the middle-aged and elderly patients, reduction and fixation via fibular can reduce postoperative complications, facilitate bone healing, relieve ankle pain and improve function recovery.
