| Abstract | BACKGROUND: Various tendinopathies occur about the ankle, but there are few publications investigating their etiology or pathoanatomy. The purpose of this investigation was to determine the gliding resistance of the tendons about the posteromedial ankle: the posterior tibial (PT), flexor digitorum longus (FDL), and flexor hallucis longus (FHL) tendons. MATERIALS AND METHODS: The gliding abilities of the posterior tibial, flexor digitorum longus, and flexor hallucis longus tendons at the ankle-hindfoot level were compared, in terms of gliding resistance, with use of a system that was developed in this laboratory. Six cadaveric specimens were used and tested in a dorsiflexed position, then in simulated flatfoot in a dorsiflexed position. RESULTS: The gliding resistance was found to be significantly greater in the simulated flatfoot in dorsiflexion compared to the dorsiflexed position with an intact arch for the PT, FDL, and FHL tendons. The gliding resistance was significantly higher in the PT tendon than FDL or FHL tendons in the flatfoot/dorsiflexion condition. There was no significant difference between the FDL and FHL tendons in resistance in either condition. CONCLUSION: We concluded that the gliding ability of the PT tendon was inferior to that of the FDL and FHL tendons in a simulated flatfoot model. CLINICAL RELEVANCE: The findings of the present study are consistent with the clinical observations that tendinitis and rupture of the PT tendon commonly occurs at the malleolar level, whereas FDL and FHL ruptures do not. A pre-existing flexible flatfoot deformity may be associated with PT tendon dysfunction in the adult due to poor gliding ability of the PT tendon. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
