Background: The definition of flatfoot remains analytically vague. Toward the purpose of establishing the standard values of the foot length and arch height in childhood and adolescence, large-scale measurement and investigation of the foot arch were conducted using a three-dimensional foot-measuring device.
Methods: Measurements of foot structure were performed on 5311 boys and 4844 girls, for a total of 20,310 ft.
Background: A comparative analysis of ankle stress X-ray findings and the condition of injured ligaments in patients with chronic lateral ankle instability was performed to determine a method of identifying the condition of injured ligaments prior to operation.
Methods: Altogether, 36 males and 80 females were included in the study. The average age at the time of operation was 29.
Background: This study evaluated the validity and inter- and intraclinician reliability of (1) the Japanese Society of Surgery of the Foot (JSSF) standard rating system for four sites [ankle-hindfoot (AH), midfoot (MF), hallux (HL), and lesser toe (LT)] and the rheumatoid arthritis (RA) foot and ankle scale and (2) the Japanese Orthopaedic Association's foot rating scale (JOA scale).
Methods: Clinicians from the same institute independently evaluated participating patients from their institute by two evaluations at a 1- to 4-week interval. Statistical evaluation was as follows.
Background: The aim of this study was to report the five scales comprising the rating system that the Japanese Society for Surgery of the Foot (JSSF) devised (JSSF standard rating system) and the newly offered interpretations and criteria for determinations of each assessment item.
Methods: We produced the new scales for the JSSF standard system by modifying the clinical rating systems established by the American Orthopaedic Foot and Ankle Society (AOFAS scales) and the Japanese Orthopaedic Association's foot rating scale (JOA scale). We also provided interpretations of each assessment item and the criteria of determinations in the new standard system.
