RÉSUMÉ
PURPOSE: Total knee arthroplasty is the main method for the treatment of advanced haemophilic knee arthritis. Due to the particularity of hemophilia, the blood management plan is the focus of the perioperative period for haemophilia patients. This study aimed to investigate the clinical effect and safety of intra-articular injection of tranexamic acid in patients with haemophilia. METHODS: This is a retrospective study. According to whether tranexamic acid is used or not, patients are divided into tranexamic acid group (n=30) and non-tranexamic acid group (n=29). Total blood loss, intraoperative blood loss, complete blood count, total amount of coagulation factor VIII (FVIII) usage, coagulation biomarkers, inflammatory biomarkers, knee range of motion, knee joint function, pain status, complication rate, and patient satisfaction were assessed and compared at a mean follow-up of 16 months. RESULTS: Injecting tranexamic acid into the knee joint cavity can effectively reduce the hidden blood loss and total blood loss (P<0.001), and reduce the patient's early postoperative inflammation biomarkers, pain status, and limb swelling. Therefore, the patient can obtain a better range of motion following total knee arthroplasty. In the long run, in terms of joint function and surgical satisfaction, there are no statistically significant differences. In addition, there are no statistically significant differences between the two groups of patients in terms of the total amount of FVIII usage, length of stay, and hospitalization expenses. CONCLUSION: In patients with haemophilia, intra-articular injection of tranexamic acid during total knee arthroplasty can effectively reduce postoperative blood loss, early postoperative inflammation levels, pain and limb swelling, and enable patients to receive higher-quality rehabilitation exercises to get better joint function. Previous studies on TKA in haemophilic patients have already demonstrated the efficacy of intra-articular injections of TXA in reducing postoperative blood loss. Our study confirms this efficacy.

Objective: In order to examine the relationship between 25-hydroxyl vitamin D and knee osteoarthritis (KOA), a meta-analysis of 8 randomized controlled trials (RCTs) publications was hereby performed. Methods: For the purpose of finding pertinent research, the databases of PubMed, Embase and the Cochrane Library were searched. Factors including tibial cartilage volume, joint space width (JSW), synovial fluid volume, and Western Ontario and McMaster Universities Arthritis Index (WOMAC) were correspondingly evaluated, and the results were expressed using SMD and 95% confidence intervals (CI). Results: The present meta-analysis evaluated the effects of vitamin D supplementation in patients with knee osteoarthritis, with 3,077 patients included. The results showed that vitamin D administration had a statistically significant impact on the amount of synovial fluid, Visual Analog Scale (VAS) and tibial cartilage. The pain and function scales of the WOMAC scale presented a statistically significant difference, and there was no discernible difference between the vitamin D and placebo groups in the stiffness scale. Additionally, bone marrow lesions and alterations in the diameter of the joint space were not influenced by the administration of vitamin D, and according to a subgroup study, a daily vitamin D supplement containing more than 2,000 IU significantly slowed the development of synovial tissue. Conclusion: Vitamin D supplementation did benefit those suffering from knee discomfort and knee dysfunction.

RÉSUMÉ
To investigate the clinical effects of specific Unified Classification System B (UCS B)-lesser trochanter periprosthetic fractures and determine whether they occur only with non-cemented stems. A retrospective analysis of 28 patients with specific UCS B2 fractures who underwent two surgical treatments, longer stem revision and internal fixation (LSRIF) and open reduction and internal fixation (ORIF), was performed. The patients were assessed at 1, 3, 6, 12, and 24 months and annually thereafter. Fracture healing, complications, Harris Hip Score (HHS), and the Short Form Health Survey questionnaire (SF-36) quality of life score were assessed at each follow-up. At the time of the last follow-up, seven patients had been lost: three were lost to contact, two died, and two were hospitalised elsewhere and unavailable for follow-up. The remaining 21 patients were followed for an average of 49.3 ± 15.4 (range: 24-74.4) months. Their average fracture healing time was 13.5 ± 1.1 (12-15.4) weeks. Complications included three cases (10.71%) of thrombus, one (3.57%) of heart failure, and one (3.57%) of pulmonary infection. There were no revisions due to prosthesis loosening, subsidence, or infection. At the last follow-up, the HHS, SF-36 mental score, and SF-36 physical score were recorded, LSRIF vs. ORIF (82.9 ± 6.6 vs. 74.7 ± 3.9, p = 0.059; 50.9 ± 7.6 vs. 38 ± 1.4, p = 0.012, and 51.7 ± 8.4 vs. 39.7 ± 3.4, p = 0.032, respectively). Specific UCS B2 fractures mostly occur with non-cemented stems. LSRIF with cables is the main treatment, while ORIF is an option for those elderly in poor condition.

Pentaxin 3 (PTX3), as a multifunctional glycoprotein, plays an important role in regulating inflammatory response, promoting tissue repair, inducing ectopic calcification and maintaining bone homeostasis. The effect of PTX3 on bone mineral density (BMD) may be affected by many factors. In PTX3 knockout mice and osteoporosis (OP) patients, the deletion of PTX3 will lead to decrease of BMD. In Korean community "Dong-gu study", it was found that plasma PTX3 was negatively correlated with BMD of femoral neck in male elderly patients. In terms of bone related cells, PTX3 plays an important role in maintaining the phenotype and function of osteoblasts (OB) in OP state;for osteoclast (OC), PTX3 in inflammatory state could stimulate nuclear factor κ receptor activator of nuclear factor-κB ligand (RANKL) production and its combination with TNF-stimulated gene 6(TSG-6) could improve activity of osteoclasts and promote bone resorption;for mesenchymal stem cells (MSCs), PTX3 could promote osteogenic differentiation of MSCs through PI3K/Akt signaling pathway. In recent years, the role of PTX3 as a new bone metabolism regulator in OP and fracture healing has been gradually concerned by scholars. In OP patients, PTX3 regulates bone mass mainly by promoting bone regeneration. In the process of fracture healing, PTX3 promotes fracture healing by coordinating bone regeneration and bone resorption to maintain bone homeostasis. In view of the above biological characteristics, PTX3 is expected to become a new target for the diagnosis and treatment of OP and other age-related bone diseases and fracture healing.

BACKGROUND: Osteoarthritis (OA) is the most prevalent form of degenerative whole-joint disease. Before the final option of knee replacement, arthroscopic surgery was the most widely used joint-preserving surgical treatment. Emerging regenerative therapies, such as those involving platelet-rich plasma, mesenchymal stem cells, and microfragmented adipose tissue (MFAT), have been pushed to the forefront of treatment to prevent the progression of OA. Currently, MFAT has been successfully applied to treat different types of orthopedic diseases. AIM: To assess the efficacy and safety of MFAT with arthroscopic surgery in patients with knee OA (KOA). METHODS: A randomized, multicenter study was conducted between June 2017 and November 2022 in 10 hospitals in Zhejiang, China. Overall, 302 patients diagnosed with KOA (Kellgren-Lawrence grades 2-3) were randomized to the MFAT group (n = 151, were administered MFAT following arthroscopic surgery), or the control group (n = 151, were administered hyaluronic acid following arthroscopic surgery). The study outcomes were changes in the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score, the visual analog scale (VAS) score, the Lequesne index score, the Whole-Organ Magnetic Resonance Imaging Score (WORMS), and safety over a 24-mo period from baseline. RESULTS: The changes in the WOMAC score (including the three subscale scores), VAS pain score, and Lequesne index score at the 24-mo mark were significantly different in the MFAT and control groups, as well as when comparing values at the posttreatment visit and those at baseline (P < 0.001). The MFAT group consistently demonstrated significant decreases in the WOMAC pain scores and VAS scores at all follow-ups compared to the control group (P < 0.05). Furthermore, the WOMAC stiffness score, WOMAC function score, and Lequesne index score differed significantly between the groups at 12 and 24 mo (P < 0.05). However, no signiï¬cant between-group differences were observed in the WORMS at 24 mo (P = 0.367). No serious adverse events occurred in both groups. CONCLUSION: The MFAT injection combined with arthroscopic surgery treatment group showed better mid-term clinical outcomes compared to the control group, suggesting its efficacy as a therapeutic approach for patients with KOA.
RÉSUMÉ
BACKGROUND: Nearly 10% of patients undergoing primary total knee arthroplasty (TKA) have valgus deformity (VD) of the knee. For severe VD of the knee, a more lateral structural release is needed to achieve balance between medial and lateral space and neutral femorotibial mechanical axis (FTMA), which is challenging and technical. AIM: To introduce a new surgical technique of resection, soft tissue release, and FTMA for Ranawat type-II VD with a 5-year follow-up. METHODS: A retrospective study was conducted on patients who underwent TKA from December 2011 to December 2014. Hip-knee-ankle (HKA), range of motion (ROM), Oxford knee score (OKS), and knee society score (KSS) were used to assess the joint activity of patients in the new theory TKA group (NT-TKA) and were compared with those of the conventional TKA group (C-TKA). RESULTS: A total of 103 people (103 knees) were included in this study, including 42 patients with an average follow-up period of 83 mo in the C-TKA group and 61 patients with an average follow-up period of 76 mo in the NT-TKA group. Six patients had constrained prosthesis, one had common peroneal nerve injury, and two had joint instability in the C-TKA group, but none of these occurred in the NT-TKA group. There were significant statistical differences in constrained prosthesis usage and complications between the groups (P = 0.002 and P = 0.034, respectively). The KSS at 1 mo post-operation for the C-TKA and NT-TKA groups were 11.2 ± 3.8 and 13.3 ± 2.9, respectively, with a significant difference (P = 0.007). However, the data of HKA, ROM, OKS KSS, and prosthesis survival rate were insignificant (P > 0.05) in both the preoperative and follow-up periods. CONCLUSION: Adopting 5°-7° valgus cut angle for VD and sacrificing 2° neutral FTMA for severe VD which cannot be completely corrected during TKA can reduce the need for soft tissue release, maintain early joint stability, reduce the use of constrained prostheses, and minimize postoperative complications.
RÉSUMÉ
BACKGROUND: Total knee arthroplasty is the leading way to treat hemophilia arthritis. At present, there is a lack of research on the influencing factors of blood loss in total knee arthroplasty for hemophilia arthritis. This study comprehensively explores the definite factors affecting the hidden blood loss in total knee arthroplasty for hemophilia patients. MATERIALS AND METHODS: Ninety-two hemophilia A patients who underwent total knee arthroplasty in our center were included. Demographics, laboratory data, surgical data, and complications were collected. The Gross equation and Sehat equation were used to calculate the estimated value of hidden blood loss. Multivariate linear regression analysis was used to determine the influencing factors of hidden blood loss. RESULT: The hidden blood loss of hemophilia A patients undergoing total knee arthroplasty was 1069.51 ± 341.99 mL, and the age was positively correlated with the hidden blood loss (P < 0.001), while tranexamic acid, FVIII prophylaxis, and incremental invivo recovery were negatively correlated with the hidden blood loss (P < 0.001, P = 0.008, P = 0.017). CONCLUSION: Elderly patients have a greater risk of blood loss, and additional preventive measures can be appropriately added. Intraoperative intra-articular injection of tranexamic acid is recommended to reduce hidden blood loss, FVIII prophylaxis is recommended for every patient. We recommend that all HA patients measure the incremental invivo recovery and develop a personalized infusion regimen of coagulation factor.

Background: Total knee arthroplasty (TKA) is recommended for haemophilic patients with end-stage arthritis. TKA combined with a one-stage extraarticular osteotomy is uncommon in the treatment of haemophilic arthritis (HA) with severe extra-articular deformities (EADs) and a history of inhibitors under the guidance of a patient-specific cutting guide (PSI). Case presentation: We reported a 20-year-old male patient with severe haemophilia, limited knee functionality, a 30° sagittal deformity on the femoral side and a history of inhibitors. We adopted the Van Creveld protocol to decrease the inhibitors. TKA and extra-articular osteotomy (EAO) were performed simultaneously and sequentially under the guidance of PSI. An appropriate central alignment of the lower limb was restored by using cement prostheses with antibiotics and femur shaft locking compression plates. The last follow-up showed that the knee function was good, the VAS score was 0, the WOMAC score was 18 and the ROM was 0°-95°. Conclision: Regular haematology management can reduce the perioperative bleeding risk in haemophilic patients treated with inhibitors. PSI plays an important role in guiding the TKA and EAO of end-stage HA patients with severe EAD.
RÉSUMÉ
Knee osteoarthritis-associated bone marrow edema-like lesions (KOA-BMLs) is a common MRI imaging feature, which is mainly manifested as abnormal bone marrow hyperintensity in subchondral bone on T2 imaging. The formation of KOA-BMLs may be related to the abnormality of lower limb force line and subchondral bone perfusion, and related histopathological studies showed that the remodeling of bone and bone marrow in these damaged areas was abnormally increased. In KOA patients, the size of BMLs can fluctuate or even disappear in a relatively short period of time, and was closely related to pain, subchondral bone cyst formation, and the progression of KOA. However, the current treatment methods for KOA-BMLs are limited, and there is no uniform guideline or expert consensus, mainly includingmedication, physical therapy and surgical treatment. This article reviews the research progress of the disease characteristics and treatment of KOA-BMLs in order to provide guidance for the clinical diagnosis and treatment of KOA-BMLs.

Surgical treatment is the main treatment for hemophilia arthritis, including synoviectomy, joint replacement and joint fusion. Synoviectomy is suitable for early hemophilia synovitis, and is divided into radiation, chemical, arthroscopy, and open operation. Radionuclides were recommended as the first choice due to its positive efficacy and less side effects, but exsit some problems such as scarcity of nuclides. Chemical synoviectomy is cheap and easy to operate, which is suitable for developing countriesm, while mutiple doses and pain after injection are main fault. Synoviectomy under arthroscope has a significant effect on the advanced lesion, but has a higher surgical risk. Open surgery with severe trauma and postoperative joint stiffness, is rarely performed. Joint replacement could effectively improve range of motion in advanced patients and is suitable for joints with high range of motion. Arthrodesis are effective in improving symptoms but lead to loss of range of motion and are suitable for joints with low range of motion. Operation for hemophilia arthritis has some problems, such as single operation, untimely diagnosis and treatment in early stage, and unsatisfactory curative effect in late stage. In addition, the treatment of hemophilia arthritis should focus on the early treatment, the formation of the whole process, the system of individual treatment concept.

BACKGROUND: In critical care medicine, mesenteric ischemia (MI) is a life-threatening disease that can be present in both critically ill patients and those undergoing major surgery. For the first time, we report a case of concealed MI with a long course after knee arthroplasty. CASE SUMMARY: A male patient underwent left total knee arthroplasty for gouty arthritis and developed a persistent fever and persistently high levels of serum infection markers after surgery. He was considered to have a periprosthetic site infection and treated with antibiotics and colchicine, periprosthetic debridement was performed, and the spacer was replaced, but no improvement was seen. At 54 d after arthroplasty, the patient developed gastrointestinal symptoms of nausea and vomiting, abdominal distention, and subsequently, cloudiness of consciousness, and hypotensive shock. Finally, the patient was diagnosed with ascending colonic mesentery ischemia with necrosis after laparotomy, which improved after right hemicolectomy. CONCLUSION: Concealed MI without gastrointestinal symptoms after major surgery is rare and easily misdiagnosed. Orthopedic surgeons need to be aware of this complication.

BACKGROUND: Osteochondritis dissecans (OCD) is a rare disease of unclear cause characterized by subchondral bone damage and overlying cartilage defects. The current report presents the results of subchondral bone as a novel target for implantation of peripheral blood stem cells (PBSCs) in the treatment of OCD. CASE SUMMARY: A 16-year-old patient diagnosed with OCD underwent subchondral bone implantation of PBSCs. Four months later, the patient's visual analog scale scores, Western Ontario and McMaster University osteoarthritis index, and whole-organ magnetic resonance imaging score improved significantly, and regeneration of cartilage and subchondral bone was observed on magnetic resonance imaging. CONCLUSION: This is the first case of OCD treated with subchondral bone as an implantation target of PBSCs, which highlights the importance of subchondral bone for cartilage repair. This treatment could be a potential option for articular cartilage and subchondral bone recovery in OCD.
RÉSUMÉ
Femorotibial mechanical axis (FTMA) is one of important factors influencing clinical effect after total knee arthroplasty (TKA). It is generally believed that the range of lower limb alignment after TKA is controlled within neutral FTMA ± 3 °, which has more advantages in improving joint function, prolonging prosthesis survival rate and reducing revision rate, and obtain better clinical results. Therefore, neutral FTMA is also considered to be the gold standard for TKA. However, with the application of computer-assisted surgery and other technologies, the alignment of FTMA is more accurate than before, but the clinical effect after surgery has not significantly improved. Some scholars have begun to question the necessity of neutral alignment of FTMA, and proposed alignment methods such as kinematics and retained residual deformity, which could achieve better clinical effects. In recent years, it has been reported that FTMA might not be the most important factor influencing postoperative clinical effects, and it is suggested that the arrangement and measurement of lower limbs and the effects on adjacent joint functions could affect clinical effect after TKA. The paper reviews neutral FTMA alignment is still an important factor for success of TKA. After a thorough evaluation according to the patient's condition, it should be appropriately applied in the case of neutral FTMA alignment; the operator should explore other factors which affect clinical outcome after TKA, and improve it to achieve the best therapeutic effect.

Steroid-associated necrosis of the femoral head (SANFH) is one of the most common and refractory chronic diseases with increasing incidence. The typical pathological changes of SANFH include decreased osteogenic differentiation, enhanced intramedullary adipocytes deposition and impaired osseous circulation. In this study, we investigated the effects and potential mechanisms of Platelet-rich plasma (PRP) on SANFH. Sixty Sprague-Dawley rats were randomly divided into the control, PRP donor, model, and PRP groups. Compared to the model group, PRP treatment significantly increased the hemorheological indexes and serum levels of bone gla-protein (BGP) and vascular endothelial growth factor (VEGF), while decreased the levels of triglyceride (TG) and total cholesterol (TC). Meanwhile, Micro-CT and histopathological stain (Hematoxylin-eosin and Alcian blue-hematoxylin/orange G staining) were performed on the femoral head for morphological and histopathological evaluation, indicating that bone trabecular microstructure and bone mineral density (BMD) were significantly improved after PRP treatment. Immunohistochemical analysis revealed that PRP remarkably up-regulated the expression of osteogenic markers including ß-catenin and alkaline phosphatase (ALP), angiogenic markers containing VEGF and platelet endothelial cell adhesion molecule-1 (CD31), while down-regulated adipogenic markers involving fatty acid-binding protein (FABP-4), and peroxisome proliferator-activated receptor gamma (PPAR-γ) in SANFH rat models. In summary, for the first time, PRP was demonstrated to prevent the development of SANFH through stimulating bone formation and vascularization as well as retarding adipogenesis.

OBJECTIVE: To investigate how to place the anteversion of acetabular prosthesis more reasonably in patients with lumbar degenerative kyphosis. METHODS: A total of 122 patients with degenerative kyphosis of lumbar spine who underwent total hip arthroplasty from December 2017 to October 2019 were included and divided into experimental group and control group, 61 cases in each group. In experimental group, there were 25 males and 36 females, with a median age of 67.0 years;the median course of disease was 46.0 months;the functional pelvic plane with acetabular anteversion was set according to different types of pelvic anterior plane bracket. In control group, there were 27 males and 34 females, with a median age of 67.0 years;the median course was 42.0 months;in control group, the anteversion was set by the traditional method. The patients were followed up for 3 months. The operation time and blood loss were recorded. The incidence of infection and dislocation within 3 months was counted. Harris score before and 3 months after operation was recorded. Functional anteversion angle of standing position was measured 3 months after operation. RESULTS: Compared with control group, there was no difference in operation time and blood loss between the two groups (P=0.918, 0.381);there was no infection between two groups within 3 months after operation;there was 1 case of hip joint dislocation in the control group and no dislocation in experimental group. There was no significant difference in Harris score before and after operation. Three months later, reexamination of pelvic standing radiographs showed that the number of patients with functional anteversion of acetabular prosthesis outside the safe area was less in experimental group thanin control group (P=0.048), and the functional anteversion angle of acetabular prosthesis was more concentrated in the range of 15 ° to 20 ° in experimental group (P<0.001). CONCLUSION: According to the preoperative evaluation and classification of patients, better functional anteversion of acetabular prosthesis can be obtained with the help of pelvic anterior plane reference bracket in hip arthroplasty with lumbar degenerative kyphosis.

ETHNOPHARMACOLOGICAL RELEVANCE: Knee osteoarthritis (KOA) is the most common chronic joint disorder worldwide, which is also a principle consideration for disability. The Bushenhuoxue formula (BSHXF) is a traditional herbal formula which widely applied to the treatment of KOA. However, its pharmacological mechanisms of action have not been clarified. AIMS OF THE STUDY: The study aimed to identify the potential targets and mechanisms of BSHXF in the treatment of KOA through pharmacology-based analyses and experimental validation. MATERIALS AND METHODS: The TCMSP database was applied to obtain the chemical compounds and targets of BSHXF, while the protein targets in KOA were determined through GeneCards and OMIM databases. The herb-compound-target and protein-protein interaction (PPI) networks were constructed for topological analyses and hub-targets screening. GO and KEGG enrichment analyses were performed on these core nodes to identify the critical biological processes and signaling pathways. Then destabilization of medial meniscus (DMM)-induced C57BL/6J mice model was established to detect the level of apoptosis via TUNEL assessment, while the expressions of CASP3, CASP8 and CASP9 were determined by immunohistochemistry. RESULTS: A total of 154 active compounds and 58 targets were predicted. DAVID, ClueGO and Metascape enrichment analyses all proved that BSHXF plays an essential role in regulating apoptosis. Moreover, 3 central nodes of BSHXF are recognized as the active factors involved in the main biological functions, suggesting a potential mechanism of BSHXF for KOA treatment. In vivo experiment revealed that BSHXF significantly inhibited apoptosis and down-regulated the expressions of CASP3, CASP8 and CASP9. CONCLUSION: Based on network pharmacology and experimental validation, our study indicated that BSHXF exerted anti-apoptosis effect through inhibiting the expressions of CASP3, CASP8 and CASP9, which could be considered as an effective method for KOA treatment.

Adolescent idiopathic scoliosis (AIS) is a common disease with the age of 10 to 18 years, the Cobb angle more than 10 ° on the coronal plane and combined with the rotation of the vertebral body without other organic lesions. The disease can lead to deformity, pain and even damage of cardiopulmonary function, which seriously affects the physical and mental health and quality of life of patients. For mild to moderate AIS patients, regular observation, braces and other conservative treatment methods can effectively delay the progress of scoliosis. For AIS patients whose conservative treatment is ineffective and reaches the surgical threshold, surgery is recommended. Currently, the prevalent surgical method is posterior vertebral body fusion represented by the pedicle screw internal fixation system, which can often achieve good clinical efficacy. In recent years, Physical Therapeutic Scoliosis Specific Exercise (PSSE) has become more and more popular because of its safety and effectiveness. At present, the specific indications for the treatment of AIS patients are gradually improving, the concept and technology of treatment are constantly updated, and the clinical efficacy is constantly improved. This article will start from two aspects of conservative treatment and surgical treatment, mainly describes the commonly used treatment methods in clinical progress and application as well as the problems faced, in order to provide a reference for the selection of clinical treatment.

METHODS: From June 2016 to April 2018, 78 patients with calcaneus were divided into observation group and control group. There were 39 patients in observation group, including 36 males and 3 females aged from 28 to 61 years old with an average of(41.7±13.3) years old; 20 patients were caused by falling down, 10 patients were caused by traffic accident and 9 patients were caused by other injuries; The time from injury to medical treatment ranged from 0.5 to 10.5 h with an average of(4.6±3.2) h; 15 patients were type II, 17 patients were type III and 7 patients were type IV according to Sanders classification; the patients began to be pressed the three points of "Xuehai(SP 10)" "Sanyinjiao(SP 6)" "Zusanli(ST 36)" for 10 min from the day of hospital admission to the day of operation, 3 times a day, and taken prescription of activating blood and dissipating blood stasis prescription orally for 5 days, one dose per day and twice a day. There were 39 patients in control group, including 34 males and 5 females aged from 26 to 62 years old with an average of (43.3±12.3) years old; 19 patients were caused by falling down, 12 patients were caused by traffic accident and 8 patients were caused by other injuries; the time from injury to medical treatment ranged from 1 to 11 h with an average of (4.4±3.7) h; 15 patients were typeII, 18 patients were type III and 6 patients were type IV according to Sanders classification; patients were given 20% mannitol intravenously for 5 days, twice a day, 125 ml each time from hospital admission. During the 5 days of admission, the degree of swelling of the affected ankle was measured and calculated by water spillover method every day. The result which was measured and calculated on the first day of admission without treatment was the degree of swelling before treatment, compared degree of swelling before operation and 1st, 2nd, 3rd and 4th day after treatment; the time needed for the first positive skin fold sign in the affected ankle and the number of cases of tension blisters between two groups before operation were observed. RESULTS: The swelling of the affected ankle on the1st, 2nd, 3rd and 4th day after treatment in the observation group separately were(12.67±0.82)%, (11.87±0.88)%, (10.65±0.92)%, (9.47±0.96)%, and lower than control group which separately were(13.31±0.98)%, (13.51±0.84)%, (12.22±0.94)%, (11.38±1.01)%; The time for the first appearance of the skin fold sign was (6.41±1.74) days in the observation group was earlier than that of the control group (8.15±2.01) days; There was no significant difference in occurrence of tension blisters between observation group(3 patients) and control group(9 patients). CONCLUSIONS: Acupressure combined with activating blood and dissipating blood stasis prescription for the treatment of early swelling of calcaneal fractures could accelerate the decline of swelling of the affected ankle, shorten the time of the first skin fold sign, reduce the incidence of tension blisters in the ankle, shorten the waiting time of operation, and the surgical treatment as soon as possible.

OBJECTIVE: To explore clinical efficacy of cannulated screw internal fixation in treating sustentaculum tali fractures with articular surface. METHODS: From August 2012 to June 2017, 13 sustentaculum tali fracture patients with articular surface were treated by cannulated screw internal fixation, including 10 males and 3 females, aged from 26 to 58 years old. Joint plane flatness was evaluated by calcaneal width, clearance distance of middle-range and posterior talar articular surface on coronal position of CT scan before operation and 1 year after operation. AOFAS score at 1 year after operation was applied to evaluate clinical efficacy. RESULTS: All patients were followed up from 9 to 70 months. The fractures were healed well from 8 to 16 weeks. No subtalar arthritis and tenosynovitis occurred. Calcaneal width before operation was from 46.2 to 52.7 mm, and decreased from 35.2 to 39.2 mm after operation; clearance distance of middle-range before operation was from 4.5 to 4.8 mm, and decreased from 1.9 to 2.2 mm after operation; clearance distance of posterior talar articular surface before operation was from 2.4 to 2.8 before operation, and decreased from 1.9 to 2.3 mm after operation. AOFAS score at 1 year after operation ranged from 77 to 94, and 1 got excellent result and 12 moderate. CONCLUSIONS: The clinical efficacy of two cannulated screws with cross internal fixation for sustentaculum tali fractures with articular surface is satisfactory, sustentaculum tali fracture could obtain good reduction, recover smooth of middle talar articular surface, and the function of feet were improved.
