ABSTRACT
Objective:To investigate the clinical efficacy of early versus delayed open reduction and internal fixation in the treatment of tibial pilon fracture. Methods:Sixty patients with tibial pilon fractures admitted to Zhejiang Veteran Hospital from May 2018 to May 2021 were included in this study. They were randomly divided into a control group and a study group ( n = 30/group) using the coin-tossing method. Patients in the control group underwent early reduction and internal fixation within 3 days after injury. Patients in the study group underwent delayed reduction and internal fixation during 7-14 days after injury. The time to bone fracture healing and the time to independent weight-bearing walking were recorded. At 3 and 6 months after surgery, the American Orthopedic Foot and Ankle Society score, Visual Analogue Scale score, clinical efficacy, and incidence of complications were compared between the two groups. Results:The time to bone fracture healing and the time to independent weight-bearing walking in the study group were (8.23 ± 0.63) weeks and (11.77 ± 0.82) weeks, respectively, which were significantly shorter than (9.57 ± 0.86) weeks and (13.40 ± 0.93) weeks in the control group ( t = 6.87, 7.21, both P < 0.001). At 3 months after surgery, American Orthopedic Foot and Ankle Society score in the study group was significantly higher than that in the control group, and the Visual Analogue Scale score in the study group was significantly lower than that in the control group ( t = 6.69, 5.16, both P < 0.001). Overall excellent and good rate of clinical efficacy in the study group was significantly higher than that in the control group (86.6% vs. 63.3%, χ2 = 4.35, P = 0.037). At 6 months after surgery, there were no significant differences in American Orthopedic Foot and Ankle Society score and Visual Analogue Scale score between the two groups ( t = 0.96, 1.12, P = 0.339, 0.267). At 6 months after surgery, there was no significant difference in the overall excellent and good rate of clinical efficacy between the study and control groups (96.6% vs. 90.0%, χ2 = 0.26, P = 0.605). The incidence of complications in the study group was significantly lower than that in the control group (3.3% vs. 26.6%, χ2 = 4.70, P = 0.030). Conclusion:Delayed open reduction and internal fixation after reducing injury to the soft tissue of the affected limbs can effectively shorten the rehabilitation cycle of tibial pilon fracture, increase short-term efficacy, and decrease the risk of postoperative complications.
ABSTRACT
BACKGROUND: Tibiotalar joint fusion ways are various, and it is a difficulty in necrotic tibiotalar joint fusion. There are few comparative studies on the repair outcomes of each implant. OBJECTIVE: To compare the effectiveness and safety of modified sliding chute bone graft plus hollow screw fixation with simple screw internal fixation and plate internal fixation for tibiotalar joint fusion. METHODS: Fifty-six patients who underwent tibiotalar joint fusion were Included, Including 16 cases of screw fixation, 22 cases of plate fixation and 18 cases of modified sliding chute bone graft plus hollow screw fixation. Ankle function was compared after simple screw internal fixation, plate internal fixation and modified sliding chute bone graft plus hollow screw fixation. The ankle foot scoring system of American Orthopedic Foot and Anlde Society was used for evaluation. At the same time, the operation time, brace fixation time and fusion time of the three surgical methods ware compared. The gait at the last follow-up was compared. The average follow-up time was 2.4 years. The experiment met the ethical requirements of the First Affiliated Hospital of Harbin Medical University. All patients provided written informed consent for study participation. RESULTS AND CONCLUSION: (1) All the patients obtained exactly bony fusion. Compared with the plate fixation group, the slide bone grafting group had significant advantages in the fusion time and the last gait (P < 0.05), and the screw fixation group had significant advantages in the operation time (P < 0.05). (2) Using the ankle foot scoring system of American Orthopedic Foot and Ankle society, there was no significant difference between the sliding chute bone graft group and the plate fixation group, but both groups were significantly better than the screw fixation group (P < 0.05). (3) Adverse events had not been found in each group. (4) These results suggest that modified sliding chute bone graft plus hollow screw fixation for anlde joint lusion can effectively improve ankle joint fusion rate compared with single screw fixation, which is effective and safe.
ABSTRACT
BACKGROUND: Sodium hyaluronate injection has been used in many musculoskeletal diseases, including knee osteoarthritis, frozen shoulder, rheumatoid arthritis, and other tendon and soft tissue pain. OBJECTIVE: To evaluate the effect of sodium hyaluronate injection and corticosteroid injection in reducing the symptoms of plantar fasciitis. METHODS: Sixty-five patients with plantar fasciitis were randomly divided into two groups: sodium hyaluronate group (32 cases) and corticosteroid group (33 cases). Two groups of patients were injected with 2.5 mL of sodium hyaluronate (25 mg/2.5 mL) and compound betamethasone (5 mg of diprosone and 2 mg of betamethasone sodium phosphate) under the guidance of ultrasound, respectively. The treatment interval was 7 days, twice in total. The Visual Analogue Scale (VAS) score, plantar fascia thickness and the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score were measured before treatment, 1 month and 3 months after treatment. RESULTS AND CONCLUSION: At 1 month after treatment, compared with the baseline data, the VAS and plantar fascia thickness of the two groups decreased, and the AOFAS ankle-hindfoot score increased (P 0.05). To conclude, corticosteroids and sodium hyaluronate are both effective to treat plantar fasciitis, but the effect of corticosteroids is better within 1 month. To avoid the potential risk of corticosteroids, sodium hyaluronate can be a substitute of corticosteroids.
ABSTRACT
Objective@#To compare the effects of indirect reduction, percutaneous anterior posterior screw and direct reduction, posterior anterior screw in the treatment of posterior malleolus fracture.@*Methods@#A retrospective analysis was made on 58 patients with posterior malleolus fracture treated by cannulated screw fixation from January 2013 to December 2017 in the Department of Orthopedics, Affiliated Hospital of Guangdong Medical University.They were divided into anterior and posterior screw group (26 cases) and posterior and anterior screw group (32 cases) according to different treatment methods.The incidence of poor screw position and other complications were compared between the two groups.Health status and ankle function at the last follow-up were compared between the two groups.@*Results@#The incidence of screw malposition in the anterior and posterior screw fixation group was 23.08%(6/26), which was significantly higher than that in the posterior screw fixation group was 3.85%(1/32). The difference between the two groups has statistically significant (χ2=5.381, P=0.020); there was no significant difference in other complications such as infection, traumatic arthritis, bone nonunion (all P>0.05). At the last follow-up, the OMA scores of AP group were (80.70±8.16)and PA group were(75.23±9.33), There were significant differences between the two scores(t=2.240, P=0.029), the AOFAS scores of AP group were (80.57±7.25) and PA group were(75.38±10.19), There were significant differences between the two scores(t=2.110, P=0.039).@*Conclusion@#The Indirect reduction and percutaneous anterior and posterior screw treatment have a high incidence of malposition of the screw, which has an impact on ankle function.Direct reduction and posterior and anterior screw fixation can significantly reduce the incidence of malposition of the screw and obtain better functional results.
ABSTRACT
Objective To investigate the clinical efficacy of buttress plating for patients with posterior pilon fracture.Methods From April 2012 to January 2015,12 patients with posterior pilon fracture of the distal tibia were treated in our hospital.They were 7 men and 5 women,30 to 56 years of age (average,41.2 years).According to the CT classification by Haraguchi et al.,5 cases belonged to type I,3 to type Ⅱ and 4 to type Ⅲ.All the patients underwent open reduction and internal fixation with buttress plate via either a posterolateral approach or a dual posterolateral-posteromedial approach.All the patients were available for follow-up.The clinical outcomes were evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and the visual analogue scale (VAS).The radiological evaluation was performed using the osteoarthritis-score (OA-score).Results The patients obtained an average follow-up of 21.2 months (range,from 12 to 30 months).Bone fractures united after an average of 15 weeks (range,from 13 to 19 weeks).The time for full weight walking averaged 16 weeks,ranging from 15 to 23 weeks.The ankle plantar flexion ranged from 36° to 42° (average,40.4°);the ankle dorsal extension ranged from 38° to 44° (average,42.6°).At the final follow-ups,the AOFAS scores ranged from 82 to 97 (average,88.2);the OA-score ranged from 0.6 to 0.8 (average,0.71);the VAS scores during rest,active motion and weight-bearing walking ranged from 0.5 to 0.8 (average,0.66),from 0.6 to 0.9 (average,0.82) and from 1.2 to 1.8 (average,1.41),respectively.No fracture malunion,implant loosening,pain or stiffness of the affected ankle was observed at the final follow-ups.Conclusion Buttress plating for posterior pilon fractures can lead to satisfactory clinical outcomes,because it ensures rigid fixation which in turn enables earlier postoperative mobilization.
ABSTRACT
OBJECTIVE@#To explore the clinical effect and safety of internal fixation of steel-wire limited loop in early Achilles tendon rupture.@*METHODS@#Seventy-six patients respectively with early transected and avulsed types of Achilles tendon rupture were selected and treated with internal fixation of steel-wire limited loop. The patients began to take exercise for their lower limbs through continous passive motion as early as possible after surgical repair, and the loops were removed after 3-5 months. Six months later, the condition of complications including Achilles tendon re-rupture, wound fistula, wound infection and skin necrosis, cutaneous sensation in sural nerve dominance region, time back to preinjury work or learning as well as time to physical activities were observed. One year later, the therapeutic effect was evaluated, and the maximum circumferences of bilateral legs and ruptured plane circumferences of Achilles tendon were measured.@*RESULTS@#The wound of all patients healed well, no complications like Achilles tendon re-rupture, wound fistula, wound infection and skin necrosis occured, and the cutaneous sensation in sural nerve dominance region was normal. The mean time back to preinjury work or learning as well as to pysical activities of all patients were respectively 10 and 22 weeks. Seventy out of 76 patients (92.1%) achieved an excellent effect, and 6 (7.9%) good effect. The excellent and good rate came up to 100%. The maximum circumference in the affected leg decreased to 2 mm averagely compared with the offside, while the ruptured plane circumferences of Achilles tendon in the affected side increased to 2.2 mm compared with the offside.@*CONCLUSIONS@#For early Achilles tendon rupture, internal fixation of steel-wire limited loop can recover the ankle function better, return to the preinjury state in the shortest time, and has few complications.
