| Popis: | Category: Hindfoot, Midfoot/Forefoot Introduction/Purpose: Cavovarus foot alignment has been significantly associated with increased rates of chronic ankle instability and osteochondral lesions of the talus. Clinical wisdom suggests that cavovarus foot alignment causes varus stress to the ankle and also predisposes individuals to peroneal tendon pathology. However, no studies have specifically explored this relationship. The purpose of this research is to investigate the association between foot alignment and peroneal tendon pathology. Methods: A retrospective case-control study was conducted of all adult patients in whom a magnetic resonance image (MRI) of the ankle was obtained for any reason at a single institution from 2015-2017. Patients were excluded if they had a charcot foot deformity or if they had undergone prior peroneal tendon, ankle, or hindfoot surgery. Arch alignment was evaluated on lateral weightbearing radiographs of the foot by measuring the adjusted navicular height. Hindfoot alignment was assessed using the Saltzman apparent moment arm method. Peroneal tendon pathology including tears, tendinosis, and tenosynovitis was documented by a fellowship-trained musculoskeletal radiologist using the MRI scan. All numerical variables were converted to categorical variables (e.g. varus, valgus, and normal alignment). Chi-square testing was utilized to determine the association between variables. Results: 195 patients were included in the study (average age 47 years, 61% female). Patients with hindfoot varus had significantly higher rates of peroneus longus (PL) and peroneus brevis (PB) tendon pathology than patients with neutral or valgus alignment (Figure 1 A, B)(PL 39% vs. 31% vs. 20%, p=0.01; PB 44% vs 27% vs. 27%, p=0.04). Patients with pes cavus demonstrated extremely high rates of peroneal tendon pathology, which was significantly higher than patients with neutral or pes planus alignment (Figure 1 C, D)(PL 71% vs. 28% vs. 9%, p |
