Abstract

Background: The aim of this study was to investigate the relationship between the radiographic bone morphology of the ankle and the observed fracture type.

Methods: We retrospectively reviewed the patients who had visited our emergency department with ankle injuries between June 2012 and July 2018. All patients were treated with open reduction and internal fixation. Patients were categorized in two groups based on the fracture patterns (groups 1 and 2). Group 1 consisted of isolated lateral malleolar fractures, while group 2 comprised bimalleolar fractures. Group 1 was further divided into two groups; namely group A and B based on their classification into Weber type B and C fractures, respectively. Four radiographic parameters were measured postoperatively by standing whole-leg anteroposterior view of the ankle; talocrural angle (TCA), medial malleolar relative length (MMRL), lateral malleolar relative length (LMRL), and the distance between the talar dome and distal fibula.

Results: One hundred and seventeen patients were included in group 1-A, 89 patients in group 1-B, and 168 patients in group 2. The values of TCA and MMRL were significantly higher in group 2 than in group 1. Lateral malleolar length/medial malleolar length ratio was also significantly different between the two groups. However, there were no significant differences between the groups in terms of LMRL and the distance between the tip of the distal fibula and talar process. LMLR and MMRL values between groups A and B were not significantly different (p=0.402 and p=0.592, respectively). However, there was a significant difference between the two groups in terms of TCA and the distance between the tip of the distal fibula and talar process.

Conclusions: The talocrural angle, medial malleolar relative length, and lateral malleolar length/medial malleolar length were significantly higher in patients with bimalleolar fracture than in patients with isolated lateral malleolar fractures.

BACKGROUND:In this study, we evaluated to the relationship between the type of accessory navicular bone (ANB) and radiological parameters of foot in patients with bilateral ANB of different types. METHODS:Patients with bilateral ANB of different types participated in this study, from May 2019 to April 2020. Patient data, including age, sex, body mass index (BMI), and presence of symptoms were obtained. We aimed to compare the radiological parameters of both the feet for evaluate the differences from one another in patients with bilateral ANB of different types (one side type 1 and contralateral side type 2) because the foot angles may differ in each person. Seven radiographic parameters were measured, including calcaneal pitch angle, talocalcaneal angle, tibiocalcaneal angle, naviculocuboid overlap, talonavicular coverage angle, anteroposterior talo-first metatarsal angle, and the lateral talo-first metatarsal angle, which evaluated hindfoot, midfoot, and forefoot alignment. RESULTS: Twenty patients (13 women and 7 men) with a mean age (and standard deviation) of 38.5 {plus minus} 12.3 years were included in the study. The patients had a mean height of 168.1 {plus minus} 7.1 cm, a mean weight of 77.2 {plus minus} 10.5 kg, and a mean BMI of 27.4 {plus minus} 4.3 kg/m2. There was no significant difference between type 1 and type 2 in all radiological parameters. There was no significant correlation between radiological parameters and age, BMI, or the presence of symptoms. CONCLUSIONS: We found that the type of ANB had no effect on the radiological measurements of the foot in which we evaluate the parameters patients with bilateral ANB of different types. Additionally, age, BMI, and the presence of symptoms, also demonstrated no correlation with the radiological parameters of the foot.

Background: The aim of this study is to compare clinical and radiologic outcomes of self-adhesive taping (SAT) or a short- leg cast (SLC) groups with base of fifth metatarsi.

Methods: Functional outcome was assessed by the Visual-Analogue-Scale Foot and Ankle (VAS-FA) at the Emergency and at 2, 4, 6, and 12 weeks. Labour loss, bone union and The American Orthopedic Foot and Ankle Score (AOFAS) at 12 weeks were also assessed.

Results: There was no difference between the SAT group and SLC group in VAS-FA scores at time of injury, 6 and 12 weeks. The SAT group had a significantly higher mean VAS-FA score at the second and fourth weeks of follow-up compared with the SLC group (P = .001 and P = .039, respectively). No correlation was observed between the fracture gap and functional scores for both groups. There was no difference in AOFAS between two groups at 12 weeks. Twenty one patients were unable to work for a mean of 38.2 days during the treatment. 10 patients with the SAT missed 37.5 days and eleven patients with the SLC g missed 40.2 (p: 0.41). The bone union was also achieved for all patients within 12 weeks.

Conclusion: Treatment with SAT in these fractures had satisfactory functional results compared with traditional SLC. Although there were no significant differences in labor loss and use of assistive devices, The VAS-FA score was significantly higher in SAT group than the SLC group at the second and fourth weeks of treatment.

Background: Many authors have highlighted the role of muscle strength imbalance around the ankle in the development of recurrent clubfoot following Ponseti treatment. However, this possible underlying mechanism behind recurrence has not been investigated sufficiently to date. This study aimed to explore whether there is a relationship between Achilles tendon elongation and recurrent metatarsus adductus deformity in children with unilateral clubfeet treated by the Ponseti method.

Methods: A retrospective chart review was performed on 20 children (14 boys and six girls; mean age, 7 years; age range, 5–9 years) with a recurrent metatarsus adductus deformity treated by the Ponseti method for unilateral idiopathic clubfoot. At the final follow-up, isometric muscle strength was measured using a portable, hand-held dynamometer in reciprocal muscle groups of the ankle. The length of the tendons around the ankle was measured ultrasonographically.

Results: The plantarflexion-to-dorsiflexion ratio was lower on the involved side (P = .001). No significant differences in the strength ratio of inversion to eversion were found (P = .4). No difference was observed in lengths of tibialis anterior and posterior tendons (P = .1), but the Achilles tendon was longer on the involved side (P = .001; P < .01). A significant negative correlation was discovered between involved-to-uninvolved Achilles tendon length ratios and involved-to-uninvolved plantarflexion strength ratios (r = –0.524; P = .02)

Conclusions: Achilles tendon elongation may be a contributor to the muscle imbalance in clubfeet with relapsed forefoot adduction treated by the Ponseti technique.
