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 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.
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 evaluate the effectiveness of Scarf osteotomy combined with Akin osteotomy in the treatment of moderate to severe hallux valgus with absorbable screws or metal screws fixation by clinical and radiological data. Methods Between March 2014 and May 2016, the Scarf osteotomy combined with Akin osteotomy was used to treat 62 patients (83 feet) with moderate to severe hallux valgus. Twenty-five patients (35 feet) were fixed by absorbable screws (group A) and 37 patients (48 feet) were fixed by metal screws (group B). The difference in gender, age, affected side, etiology, severity, disease duration, preoperative hallux valgus angle (HVA) and first-second intermetatarsal angle (1-2IMA) measured in weight-bearing anteroposterior X-ray film, preoperative American Orthopaedic Foot and Ankle Society (AOFAS) scores and visual analogue scale (VAS) scores between 2 groups (P>0.05). The complications and healing time of 2 groups were recorded and compared. At last follow-up, the AOFAS and VAS scores, and HVA, 1-2IMA measured by weight-bearing anteroposterior X-ray film were used to evaluate the effectiveness. Results All incisions healed by first intention and no incision-related complication occurred in the two groups after operation. Both groups were followed up, the follow-up time in group A was 12-36 months (mean, 24.4 months) and in group B was 14-38 months (mean, 25.7 months). In group A, 1 foot was complicated with hallux varus, 2 feet had mild stiffness, 1 foot appeared metastatic metatarsal pain, and in group B was 2, 3, 2 feet, respectively. There was no recurrence of hallux valgus in both groups. The difference in the incidence of complications between the two groups after the first operation was not significant (χ2=0.275, P=0.843). The removal rate of internal fixator in group B was 89.2% (33 cases) during the second operation, among which 3 cases had screw slip and 1 case had screw fracture. And 10.8% (4 cases) refused the second removal operation due to their age. Postoperative X-ray films showed that both groups had good healing at the osteotomy site, and there was no significant difference in healing time between the two groups (t=1.633, P=0.285). At last follow-up, the AOFAS score, VAS score, HVA, and 1-2IMA were significantly improved in the two groups when compared with preoperative ones (P<0.05); but no significant difference was found between the two groups (P>0.05). Conclusion The effectiveness of Scarf osteotomy combined with Akin osteotomy in the treatment of moderate to severe hallux valgus is significant, with few complications. Compared with being fixed by metal screws, being fixed by absorbable screws has the same effectiveness, but can avoid the risk of second operation to remove the internal fixator.
Objective To assess the effectiveness of supramalleolar osteotomy (SMOT) as a therapeutic intervention for varus-type ankle arthritis, while also examining the associated risk factors that may contribute to treatment failure. MethodsThe clinical data of 82 patients (89 feet) diagnosed with varus-type ankle arthritis and treated with SMOT between January 2016 and December 2020 were retrospectively analyzed. The patient cohort consisted of 34 males with 38 feet and 48 females with 51 feet, with the mean age of 54.3 years (range, 43-72 years). The average body mass index was 24.43 kg/m2 (range, 20.43-30.15 kg/m2). The preoperative tibial anterior surface angle (TAS) ranged from 77.6° to 88.4°, with a mean of 84.4°. The modified Takakura stage was used to classify the severity of the condition, with 9 feet in stage Ⅱ, 41 feet in stage Ⅲa, and 39 feet in stage Ⅲb. Clinical functional assessment was conducted using the Maryland sore, visual analogue scale (VAS) score, and psychological and physical scores in Health Survey 12-item Short From (SF-12). Radiology evaluations include TAS, talar tilt (TT), tibiocrural angle (TC), tibial medial malleolars (TMM), tibiocrural distance (TCD), tibial lateral surface angle (TLS), and hindfoot alignment angle (HAA). The results of clinical failure, functional failure, and radiology failure were statistically analyzed, and the related risk factors were analyzed. ResultsThe operation time ranged from 45 to 88 minutes, with an average of 62.2 minutes. No complication such as fractures and neurovascular injuries was found during operation. There were 7 feet of poor healing of the medial incision; 9 pin tract infections occurred in 6 feet using external fixator; there were 20 cases of allograft and 3 cases of autograft with radiographic bone resorption. Except for 1 foot of severe infection treated with bone cement, the remaining 88 feet were primary healing, and the healing area was more than 80%. All patients were followed up 24-82 months, with an average of 50.2 months. Maryland score, VAS score, SF-12 psychological and physiological scores, and TAS, TC, TLS, TCD, TT, TMM, HAA, and Takakura stage were significantly improved at last follow-up (P<0.05). Postoperative clinical failure occurred in 13 feet, functional failure in 15 feet, and radiology failure in 23 feet. Univariate analysis showed that obesity, TT>10°, and Takakura stage Ⅲb were risk factors for clinical failure, HAA≥15° and Takakura stage Ⅲb were risk factors for functional failure, and TT>10° was risk factor for radiographic failure (P<0.05). Further logistic regression analysis showed that TT>10°, HAA≥15°, and TT>10° were risk factors for clinical failure, functional failure, and radiographic failure, respectively (P<0.05). Conclusion SMOT is effective in the mid- and long-term in the treatment of varus-type ankle arthritis, but it should be used with caution in patients with obesity, severe hindfoot varus, severe talus tilt, and preoperative Takakura stage Ⅲb.
