Tibial Growth Plate

Category: Ankle Arthritis Introduction/Purpose: Juvenile idiopathic arthritis is a broad term that describes a clinically heterogeneous group of arthritides of unknown cause, which begin before 16 years of age persist for more than 6 weeks. It is one of the main diseases affecting Paediatric age group Joints in a form of a chronic, long standing and debilitating disease. It is estimated that 1 in 1000 children present with JIA in the UK alone. Radiographic progression of the disease occurs early, and if not addressed may result in permanent joint destruction and poor functional outcomes. The ankle is frequently involved, but it is unclear whether this is due to synovitis, tenosynovitis. To date, no evidence of combined therapies or integrated care for juvenile idiopathic arthritis patients with F&A problems exists. Methods: JIA patients with ankle involvement presented to orthopedic foot and ankle services between 2012-2017 were include. All patients had weight bearing x-rays ankle measuring Tibio talar angle, also underwent Ankle MRI following standard hospital MRI protocols. The MRI scans were used to measure the affected areas in talus. Talus was divided into 4 anatomical regions (Anterio-medial, Anterio-lateral, posterior-medial, posterolateral). lesion involving wider areas were recorded as two or more regions accordingly, i.e.: AM and PM involvement at the same time were given yes for area of involvement in both region and recorded separately. Bilateral Ankles involvement were also recorded. Tibial growth plate involvement in these patients on the MRI scan was recorded. Demographic data was collected along with side, disease pattern, age at diagnosis and age at presentation to F&A speciality and patients requiring surgical intervention. Measurements were carried out by two in dependent orthopaedics F&A surgeons. Results: 14 patients were included in this study with a total of 17 ankles. 12 were females (N=12, 85.7%). Mean age was between 8-21 years (15.0 ± 4.08, M±SD). Time to presentation was 2.9 to 8.4 years (5.1 ± 1.4 years). 5 had Oligo-articular involvement (37.5%),9 patients had polyA (64.2%). 11/17 Right Ankles (64.7%), 3 left (21.4%). 3 bilateral (21.4%). 11/17 Ankles in Varus (64.7%), 1/17 valgus (5.8%), 5/17 neutral (29.4%). Mean Tibiotalar angle was 80° ± 13.5° (Range 49° - 100°). 12/17(70.5%) had involvement of the antero-medial part of the talus,1/17(5.8%)antero-lateral, 8/17 postero-medial(47.06%), 3/17(17.6%) postero-lateral . All the patients with postero-lateral involvement, they also had postero-medial involvement. (p=0.043). 13/17 ankles (76.4%) had tibial growth plate involvement. 5 patients (35.7%) had subsequent operations. Conclusion: This study shows a pattern of involvement in the talus and the effect this disease has on Tibiotalar alignment. This needs to be confirmed on a larger number of patients. And highlights the need for an earlier presentation of these patients to F&A surgeon to prevent the disease sequela. Further research is required to study the tibial growth plate involvement for its contribution to the varus / valgus deformity in a chronological method. Further research is also required to quantify the time frame for disease and deformity progression in the Tibiotalar Joint.

Tibial dyschondroplasia (TD) is a tibia bone problem in broilers. Anacardic acid (AA) is a traditional Chinese medicine, which is commonly used to treat arthritis in human. The purpose of the present study is to investigate the effect of AA against TD. A total of 300 day-old poultry birds were equally divided and distributed into three different groups: Control, TD and AA groups. The results showed that the feed conversion ratio was significantly lower in the TD group than control chickens. The tibia bone parameters including weight, length and width were of low quality in TD chickens, while the width of the tibial growth plate was enlarged remarkably. Whereas, in the AA treatment group, the tibia bone parameters showed improvement and tend to return to normal. The antioxidant parameters level of glutathione peroxidase (GSH-Px), superoxide dismutase (SOD), total and antioxidant capacity (T-AOC) was significantly decreased, while malondialdehyde (MDA) level was increased significantly in TD affected chickens. AA administration restored the antioxidant parameters significantly. The gene expression revealed a decrease in Wnt4 expression in TD chickens as compared to control chickens, while AA treatment up-regulated the Wnt4 expression. The present study demonstrates that the AA plays an important role to prevent the lameness and restore the size of tibial growth plate of chickens by regulating the expression of Wnt4.
