Objective To give a review and commentary on the treatment of acute foot and ankle injuries. Methods Based on the treatment experience and recent l iterature, a commentary on acute foot and ankle injuries were given, included the basic and cl inical research results, evaluation before operation, and treatment methods of the soft tissue and bone injuries. Results The treatment of acute foot and ankle injuries is still a hot point in orthopaedic surgery. Operative and non-operative treatment of fresh Achilles tendon rupture can achieve satisfactory results, and early weight-bearing do not increase the re-rupture rate. The time delay between first debridement and injury within 24 hours does not increase the infection rate. For the treatment of severe ankle fractures, attentions should be paid to the cartilage injury, and anatomic reduction, good real ignment, and the congruity recovery are very important. The treatment determination of calcaneal fractures depends on the fully understanding injury mechanisms, classifications, and treatment method. Talus fractures should try to be treated by experienced surgeons. Operation and fixation methods of Lisfranc injury depends on different injury types. Conclusion Acute foot and ankle injuries are common in cl inical, to achieve a satisfactory result in evaluation and treatment, it is important to have a fully evaluation of the injury type, and choose the best operation time and suitable treatment methods, as well as to fully understand the biomechanical characteristics of different regions.
Objective To review the progress in the diagnosis and treatment of chronic disorders of achilles tendon. Methods Recent l iterature concerning the diagnosis and treatment of chronic disorders of achilles tendon was revi ewed. Results Ultrasonography and MRI were commonly used for diagnoses, and MRI could provide extensive informationfor the choice of therapy protocol. Nonsurgical therapy was the mainstay of treatment for most patients with overuse syndromes, surgical techniques for patients due to no effect in the conservative treatment and with chronic rupture, the cl inical treatment project should be determined based on the cl inical evaluation. Conclusion The surgical indication of chronic disorders of achilles tendon remains controversial, the long-term results of each treatment method are unknown, the randomized prospective studies are still required.
Objective To summarize the diagnosis and treatment of fibular fracture in ankle fracture. MethodsRelevant literature at home and abroad in recent years was widely consulted, and various types of fractures were discussed and summarized according to Danis-Weber classification. ResultsConservative treatment is not an ideal treatment for type A avulsion fracture. The operation method should be determined according to the position and size of bone mass. For simple type B fracture, both conservative treatment and surgical treatment can achieve good results. When the position of type C fracture is high and does not affect the stability of ankle joint, it can be treated conservatively, while when the position is low and affects the stability of ankle joint, it needs surgical treatment. ConclusionFirst of all, whether the fibular fracture in the ankle fracture is stable or not should be determined. Whether it is treated surgically or not, the purpose is to restore the tibiofibular syndesmosis and restore the motor function of the ankle.
ObjectiveTo explore the classification, diagnosis, and clinical treatment of Achilles tendinopathy.MethodsThe literature about Achilles tendinopathy at home and abroad was reviewed. The research results of classification and terms, imaging diagnosis, and clinical treatment of Achilles tendinopathy were summarized.ResultsThe classification and name of Achilles tendinopathy are not completely unified, and the concept is vague, the cause of disease is not clear. There are many treatment plans, but there is no effective evidence-based medicine research.ConclusionThe diagnosis and treatment of Achilles tendinopathy is complicated. According to the characteristics of Achilles tendon anatomy and etiology, the classification and definition of Achilles tendinopathy need to be further studied in order to guide clinical treatment more effectively and facilitate experience exchange and learning.
ObjectiveTo review the pathological characteristics of calcaneal fracture malunions and the research progress of surgical treatment, so as to provide a reference for standardized clinical diagnosis and treatment. Methods The relevant research literature on calcaneal fracture malunions at home and abroad in recent years was reviewed. And the pathological characteristics, imaging manifestations, classification and the latest surgical treatment strategies of calcaneal fracture malunions were systematically expounded. Results Malunion may ensue after calcaneal fractures if conservative treatment fails or surgical intervention is improperly performed, leading to abnormal foot biomechanics and severe functional impairment. Typical pathological changes include three-dimensional morphological disorders of the calcaneus (abnormal width, height loss, and varus-valgus deformity), collapse of the subtalar articular surface accompanied by joint mismatch, secondary joint degeneration, Achilles tendon contracture, and lateral soft tissue impingement syndrome. Given the complex pathological anatomy after malunion, surgical plans should be individually tailored. The clinically used Stephens-Sanders classification and Zwipp-Rammelt classification provide a reliable basis for the accurate selection of treatment modalities. Staged treatments such as subtalar arthrodesis, osteotomy correction, and soft tissue release can effectively improve ankle and foot function. ConclusionIn recent years, the biomechanical mechanisms, imaging evaluation systems, and reconstructive surgical strategies of calcaneal fracture malunion have become research hotspots. The selection of treatment plans should take into account specific clinical symptoms and morphological changes of the calcaneus, which is crucial for subsequent recovery. In the future, it is necessary to focus on individual differences, promote the integration of diagnosis and treatment, establish evidence-based guidelines, and achieve accurate and long-term deformity correction and functional reconstruction.
ObjectiveTo explore the effectiveness of modified internal fixation and fusion in treatment of type Ⅱ painful accessory navicular (PAN) in adults.MethodsBetween January 2016 and December 2017, 29 patients (37 feet) with type Ⅱ PAN were treated with modified internal fixation and fusion. There were 12 males and 17 females with an average age of 41.4 years (range, 18-50 years). The injury caused by sprain in 24 cases and no obvious inducement occurred in 5 cases. All patients received conservative treatment for more than 6 months with no significant improvement. The effectiveness was evaluated by American Orthopaedic Foot and Ankle Society (AOFAS) score before operation and at last follow-up. The inclination angle of calcaneus, the first metatarsal angle of talus, the inclusion angle of talonavicular joint, and the second metatarsal angle of talus were measured on X-ray films.ResultsSuperficial infection of incision occurred in 1 case after operation, and the incision healed after enhanced dressing change. The incisons of the other patients healed by first intention. There was no deep infection or osteomyelitis. All patients were followed up 12-33 months (mean, 25.1 months). X-ray films showed that the articular surfaces healed at 2-5 months after operation, with an average of 3.4 months. No loosening or rupture of internal fixator was found during the follow-up. At last follow-up, the pain, function, alignment scores, and total score of AOFAS were significantly improved when compared with those before operation (P<0.05). The inclusion angle of talonavicular joint, the first metatarsal angle of talus, and the second metatarsal angle of talus were also significantly improved when compared with those before operation (P<0.05). But there was no significant difference in the inclination angle of calcaneus between pre- and post-operation (t=1.097, P=0.276).ConclusionModified internal fixation and fusion in treatment of type Ⅱ PAN can effectively relieve the symptoms and obtain good recovery of feet function with less complications.
Objective To compare the efficacy of the fourth-generation minimally invasive technique—minimally invasive extra-articular metaphyseal distal transverse osteotomy (META) and Chevron osteotomy in treatment of hallux valgus. Methods A total of 80 patients with hallux valgus, who underwent single-foot surgery between July 2023 and January 2025 and met the inclusion criteria, were included in the study. Among them, 40 patients were treated with META and 40 with Chevron osteotomy. There was no significant difference in baseline data between the two groups (P>0.05), including gender, age, height, weight, body mass index, disease duration, lesion site, hallux valgus deformity degree, as well as preoperative scores of each item (pain, function, alignment, total score) in the American Orthopaedic Foot and Ankle Society Hallux Metatarsophalangeal-Interphalangeal Joint Scale (AOFAS-Hallux-MTP-IP), scores of each item (pain, walking/standing, social interaction, total score) in the Manchester-Oxford Foot Questionnaire (MOXFQ), hallux valgus angle (HVA), intermetatarsal angle (IMA), distal metatarsal articular angle (DMAA), sesamoid position, and the 1st metatarsal head morphology. The postoperative AOFAS-Hallux-MTP-IP scores, MOXFQ scores, as well as HVA, IMA, DMAA, the 1st metatarsal head morphology, and sesamoid position measured based on weight-bearing foot X-ray films were compared between the two groups; the occurrence of postoperative complications was recorded. Results All patients in both groups were followed up 6-18 months, and there was no significant difference in the follow-up time between the two groups (P>0.05). At last follow-up, the scores of all items in AOFAS-Hallux-MTP-IP in both groups were higher than those before operation, and the scores of all items in MOXFQ were lower than those before operation, with significant differences (P<0.05); there was no significant difference in the change values of all items in MOXFQ between the two groups (P>0.05). The change value in AOFAS function score in the META group was significantly higher than that in the Chevron osteotomy group (P<0.05), while there was no significant difference in the change value of AOFAS pain score, alignment score, and total score between the two groups (P>0.05). After operation, 1 case (2.5%) of superficial incision infection and 2 cases (5.0%) of numbness around the incision occurred in the Chevron osteotomy group, while only 2 cases (5.0%) of numbness around the incision occurred in the META group. Imaging reexamination showed that HVA, IMA, and DMAA in both groups were signifncatly smaller than those before operation (P<0.05), and there was no significant difference in the change values of the above angles between the two groups (P>0.05). The 1st metatarsal head morphology and sesamoid position in the META group were better than those in the Chevron osteotomy group after operation, with significant differences (P<0.05). Conclusion Both META and Chevron osteotomy can correct hallux valgus deformity, improve foot function, and relieve pain, but META has more advantages in correcting metatarsal rotation and reducing dislocated sesamoids.
Objective
To evaluate the short-term effectiveness of talonavicular arthrodesis for Müller-Weiss disease.
Methods
Between May 2013 and February 2015, 13 patients with Müller-Weiss disease were treated with talonavicular arthrodesis. There were 11 females and 2 males with an average age of 59 years (range, 42-67 years). The disease duration was 8-20 years (mean, 13 years). According to Maceira stage, there were 7 cases of stage Ⅲ, 6 cases of stage Ⅳ. The foot longitudinal arch height measured on weight-bearing X-ray films was (43.1±1.8) mm; the Meary angle and talocalcaneal angle measured on lateral X-ray films were (–2.8±2.3)° and (5.8±2.4)°, respectively; the calcaneal valgus angle measured on Saltzman position X-ray films was (–2.0±0.7)°. The American Orthopaedic Foot and Ankle Society (AOFAS) score was 43.5±12.4, and visual analogue scale (VAS) score was 7.3±1.5.
Results
All the patients were followed up 14-39 months (mean, 20 months). The symptoms of foot pain and intermittent claudication disappeared in all patients. All cases achieved bony union, the fusion time was 12-16 weeks (mean, 13 weeks). There was no complications such as wound infection, skin necrosis, or internal fixator broken. At last follow-up, the foot longitudinal arch height, Meary angle, talocalcaneal angle, and calcaneal valgus angle were (52.5±2.2) mm, (1.3±2.2)°, (16.5±3.7)°, and (0.4±0.7)°, respectively; the AOFAS score and VAS score were 83.8±9.1 and 1.0±0.4, respectively; all were significantly improved when compared with preoperative ones (P<0.05).
Conclusion
If the subtalar and calcaneocuboid joints are relatively healthy, talonavicular arthrodesis may be a reliable and effective surgical option for Müller-Weiss disease that is resistant to conservative treatment.
Objective To investigate the effectiveness of calcaneal V-shaped osteotomy combined with subtalar arthrodesis in the treatment of Stephens Ⅱand Ⅲ calcaneal fracture malunion. MethodsThe clinical data of 24 patients with severe calcaneal fracture malunion treated by calcaneal V-shaped osteotomy combined with subtalar arthrodesis between January 2017 and December 2021 were retrospectively analyzed. There were 20 males and 4 females with an average age of 42.8 years (range, 33-60 years). Conservative treatment of calcaneal fracture failed in 19 cases and operation failed in 5 cases. Stephens classification of calcaneal fracture malunion was type Ⅱ in 14 cases, and type Ⅲ in 10 cases. Preoperative B?hler angle of calcaneus was 4.0°-13.5° (mean, 8.6°), Gissane angle was 100°-152° (mean, 119.3°). The time from injury to operation was 6-14 months (mean, 9.7 months). American Orthopedic Foot and Ankle Society (AOFAS) ankle and hindfoot score and visual analogue scale (VAS) score were used to evaluate the effectiveness before operation and at last follow-up. Bone healing was observed and the healing time was recorded. The talocalcaneal height, talus inclination angle, Pitch angle, calcaneal width, and hindfoot alignment angle were measured. Results Necrosis of the cuticle edge of the incision occurred in 3 cases, which were cured by dressing change and oral administration of antibiotic therapy. The other incisions healed by first intention. All the 24 patients were followed up 12-23 months, with an average of 17.1 months. The foot shape of the patients recovered well, the shoes were restored to the size before injury, and there was no anterior ankle impingement. Bone union was achieved in all patients, and the healing time ranged from 12 to 18 weeks, with an average of 14.1 weeks. At last follow-up, no adjacent joint degeneration occurred in all patients; 5 patients had mild foot pain during walking, which had no significant impact on daily life and work; no patient needed revision surgery. The AOFAS ankle and hindfoot score was significantly higher than that before operation (P<0.001), the results were excellent in 16 cases, good in 4 cases, and poor in 4 cases, and the excellent and good rate was 83.3%. The VAS score, talocalcaneal height, talus inclination angle, Pitch angle, calcaneal width, and hindfoot alignment angle were significantly improved after operation (P<0.001). ConclusionCalcaneal V-shaped osteotomy combined with subtalar arthrodesis can effectively relieve hindfoot pain, correct talocalcaneal height, restore talus inclination angle, and reduce the risk of nonunion after subtalar arthrodesis.
Objective
To investigate the functional outcomes of buttress plate fixation and simple screws fixation for the treatment of supination-adduction type-II medial malleolar fractures so as to provide reference for selection of internal fixation.
Methods
Between March 2009 and December 2012, 53 patients with supination-adduction type-II medial malleolar fractures were treated with open reduction and internal fixation. Of them, buttress plate fixation was used in 30 cases (buttress plate fixation group), and screws fixation was used in 23 cases (screw fixation group). There was no significant difference in age, gender, injury cause, injury side, disease duration, and combined injuries between 2 groups (P>0.05). Complications and full weight-bearing time were recorded; the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and the visual analogue scale (VAS) were used to evaluate the functional outcomes. Post-operative anteroposterior and lateral X-ray films were taken to evaluate fracture reduction and union condition. And the treatment failures were recorded.
Results
There was no significant difference in incision related complication rate and infection rate between 2 groups (P>0.05). The patients were followed up 46-91 months (mean, 64.5 months) in buttress plate fixation group and 44-86 months (mean, 59.5 months) in screw fixation group. The full weight-bearing time of the buttress plate fixation group was significantly shorter than that of screw fixation group (t=2.05,P=0.04). During follow-up time, malunion and nonunion occurred in 2 cases and 1 case of screw fixation group; anatomic reduction and bony union were observed in the other patients of 2 groups. The union time showed no significant difference between 2 groups (t=1.06,P=0.30). No significant difference was found in AOFAS score and good and excellent rate, VAS score, operation failure rate, and traumatic osteoarthritis rate between groups (P>0.05).
Conclusion
For patients with supination-adduction type-II medial malleolar fracture, the angle between fracture line and tibial axial line is too small to be fixed firmly with simple screws fixation, with a relatively higher failure rate. And buttress plate fixation can reach rigid fixation, and has better functional outcomes.
