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.
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.
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.
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.
ObjectiveTo evaluate the short-term effectiveness of the first ray tri-plane osteotomy and other metatarsal basal osteotomy in treatment of hallux valgus with moderate and severe metatarsus adductus.MethodsBetween February 2012 and September 2016, 10 patients (12 feet) of hallux valgus with moderate and severe metatarsus adductus were admitted and treated with the first ray tri-plane osteotomy and other metatarsal basal osteotomy and lateral soft tissue release. There were 1 male (2 feet) and 9 females (10 feet) with an average age of 34.5 years (range, 21-55 years). The disease duration ranged from 3 to 10 years (mean, 5.8 years). The degree of metatarsal adductus was moderate in 4 feet and severe in 8 feet according to modified Sgarlato measurement method. Preoperative American Orthopaedic Foot and Ankle Society (AOFAS) score was 46.4±9.3. The metatarsus adductus angle (MAA) was (25.41±3.66)°, hallux valgus angle (HVA) was (41.42±9.67)°, and the first-second intermetatarsal angle (1-2IMA) was (10.72±2.26)°.ResultsAll incisions healed by first intention. All patients were followed up 18-24 months, with an average of 21.4 months. One patient (1 foot) had metastatic metatarsalgia after operation, but the symptoms disappeared after symptomatic treatment. X-ray re-examination showed that all osteotomies healed, and the healing time was 2.4-3.2 months, with an average of 2.8 months. At last follow-up, MAA was (8.42±0.71)°, HVA was (13.29±1.03)°, 1-2IMA was (4.41±0.48)°, and AOFAS score was 89.8±5.9. There were significant differences in clinical and radiographic indexes between pre- and post-operation (P<0.05).ConclusionThe first ray tri-plane osteotomy combined with other metatarsal basal osteotomy has a significant short-term effectiveness in the treatment of hallux valgus with moderate and severe metatarsus adductus.
Objective To summarize the progress of clinical diagnosis and treatment of diabetic Charcot neuroarthropathy (CNO) of foot and ankle to provide reference for clinical treatment. Methods The research literature on diabetic CNO of foot and ankle at home and abroad was widely reviewed, and the stages and classification criteria of CNO were summarized, and the treatment methods at different stages of the disease course were summarized. Results CNO is a rapidly destructive disease of bone and joint caused by peripheral neuropathy, which leads to the formation of local deformities and stress ulcers due to bone and joint destruction and protective sensory loss, which eventually leads to disability and even life-threatening. At present, the modified Eichenholtz stage is a commonly used staging criteria for CNO of foot and ankle, which is divided into 4 stages by clinical and imaging manifestations. The classification mainly adopts the modified Brodsky classification, which is divided into 6 types according to the anatomical structure. The treatment of diabetic CNO of foot and ankle needs to be considered in combination with disease stage, blood glucose, comorbidities, local soft tissue conditions, degree of bone and joint destruction, and whether ulcers and infections are present. Conservative treatment is mainly used in the active phase and surgery in the stable phase. Conclusion The formulation of individualized and stepped treatment regimens can help improve the effectiveness of diabetic CNO of foot and ankle. However, there is still a lack of definitive clinical evidence to guide the treatment of active and stable phases, and further research is needed.
Objective To investigate the effectiveness and biomechanical analysis of 3 fixation methods of screw anterior-posterior fixation (SAPF), screw posterior-anterior fixation (SPAF), and buttress plate fixation (BPF) in treatment of posterior Pilon fractures. Methods Fifteen fresh-frozen skeleto-ligamentous lower leg specimens were harvested to establish the models of posterior Pilon fracture, and then fracture was fixed with BPF (n=5), SAPF (n=5), and SPAF (n=5). Vertical force was loaded to internal fixation failure in a speed of 1 cm/minute with servohydraulic testing machine. The instantaneous loads of 1 mm and 2 mm steps and the failure modes were recorded. Between May 2008 and December 2011, 56 patients with posterior Pilon fracture were treated with SAPF (SAPF group) in 11 cases, or SPAF (SPAF group) in 26 cases, or BPF (BPF group) in 19 cases. There was no significant difference in age, gender, injury cause, side, disease duration, and complications among groups (P gt; 0.05). Clinical and radiographic examinations were used to assess the reduction and healing of fracture; the American Orthopaedic Foot and Ankle Society (AOFAS) ankle-hindfoot score and the visual analogue scale (VAS) were used to evaluate the functional outcomes. Results No breaking or bending was observed in all specimens, fixation failure was caused by cancellous bone compression. The instantaneous loads of 1 mm and 2 mm steps were the largest in BPF group, larger in SPAF group, and smallest in SAPF group, showing significant differences among 3 groups (P lt; 0.05). A total of 47 cases were followed up 16-54 months (9 in SAPF group, 22 in SPAF group, and 16 in BPF group), with a mean time of 35.2 months. Fixation failure was found in 2 cases of SAPF group; the other cases obtain bony union within 3 to 4 months (mean, 3.2 months) with no fixation failure. The AOFAS score was significantly lower in SAPF group than in SPAF and BPF groups (P lt; 0.05), but no significant difference was found between SPAF and BPF groups (P gt; 0.05). The VAS score was significantly higher in SAPF group than in SPAF and BPF groups (P lt; 0.05), but no significant difference was found between SPAF and BPF groups (P gt; 0.05). Conclusion SAPF could not reach enough fixation strength for the posterior Pilon fracture; both SPAF and BPF could reach rigid fixation, and have good effectiveness. And from the biomechanical points, BPF could reach better fixation strength than screw fixations.
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 Böhler 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.
ObjectiveTo investigate the short-term effectiveness of talonavicular joint arthrodesis and calcaneus osteotomy in the treatment of Müller-Weiss disease. MethodsBetween June 2015 and February 2017, 14 patients diagnosed Müller-Weiss disease, who were ineffective on conservative treatment, were treated with talonavicular joint arthrodesis and calcaneus osteotomy. There are 3 males and 11 females, with an average age of 46.2 years (range, 35-56 years). According to the Maceira grading criteria, 5 patients were rated as stage Ⅲ and 9 patients as stage Ⅳ. The disease duration ranged from 4 to 12 years (mean, 7 years). Preoperative X-ray films showed that all patients were not accompanied with adjacent joint arthritis. The hindfoot axis on Saltzman view was (9.8±2.8)°, calcaneal pitch angle (CPA) on lateral position was (14.7±5.1)°, Meary angle on lateral position was (4.8±2.8)°, and talar 1 meta-tarsal angle (T1MA) on anteroposterior position was (25.0±7.3)°. Preoperative visual analogue scale (VAS) score was 5.9±1.5, American Orthopedic Foot Ankle Society (AOFAS) ankle-hindfoot score was 58.8±17.6. ResultsAll patients were followed up 14-27 months (mean, 22.3 months). Medial numbness and incision infection occurred in 2, 2 cases, respectively. The other patients had no obvious discomfort. At last follow-up, VAS score was 1.6±1.3 and AOFAS score was 90.6±2.7, showing significant differences when compared with preoperative ones (t=8.18, P=0.00; t=–6.95, P=0.00). X-ray films showed that the talonavicular joint and calcaneus osteotomy achieved bony healing. The hindfoot axis on Saltzman view was (–2.5±2.7)°, CPA on lateral position was (25.0±5.2) °, Meary angle on lateral position was (2.6±2.1)°, T1MA on anteroposterior position was (8.1±3.8)°. There was no significant difference in Meary Angle between pre- and post-operation (t=1.53, P=0.15). And there were significant differences in the hindfoot axis, CPA, and T1MA between pre- and post-operation (t=11.93, P=0.00; t=–8.89, P=0.00; t=8.05, P=0.00). ConclusionFor Müller-Weiss disease patients without adjacent joint arthritis, who are ineffective on conservative treatment, the satisfied short-term effectiveness can be obtained when treated by talonavicular joint arthrodesis and calcaneus osteotomy.
Objective To compare the functional and radiological outcomes of supramalleolar osteotomy (SMOT) between with and without fibular osteotomy for varus ankle osteoarthritis. Methods Between April 2009 and April 2014, 41 patients (41 feet) with mid-staged varus ankle osteoarthritis were treated with SMOT. Fibular osteotomy was not performed in 19 cases (group A), and fibular osteotomy was performed in 22 cases (group B). There was no significant difference in gender, age, side, body mass index, osteoarthritis stage, pathogeny, American Orthopedic Foot and Ankle Society (AOFAS) ankle-hind score, ankle osteoarthritis scale (AOS) pain and function scores, range of motion (ROM) of the ankle joint, tibial articular surface angle (TAS), talar tilt angle (TT), tibiocrural angle (TC), and tibial lateral surface angle (TLS) between 2 groups (P>0.05). The bone union was observed after operation, and functional and radiological outcomes were compared between 2 groups at last follow-up. Results All incisions healed by stage I, and no surgery related complications occurred. The mean follow-up time was 36.6 months (range, 16-55 months). Pain and limited activity were observed in 1 case of groups A and B respectively, and ankle arthrodesis was performed. All cases achieved bony union; the bone union time was (3.6±0.4) months in group A and (3.9±0.7) months in group B, showing no significant difference (t=1.61,P=0.12). At last follow-up, no significant difference was found in TAS, TLS, TT, and TC between groups (P>0.05). However, group B was significantly better than group A in improvement of TT and TC (P<0.05). The AOFAS ankle-hind score, AOS pain and function scores, ROM of the ankle joint showed no significant difference between groups (P>0.05). According to the modified Takakura stage, the improvement rates of groups A and B were 55.6% and 57.1%, respectively; no significant difference was found between 2 groups (χ2=0.01,P=0.92). Conclusion SMOT with fibular osteotomy is helpful in correction of TT and TC in patients with relative longer fibula.
