Objective: The aim of this study was to present data about the prevalence and distribution of sesamoid bones of the hands and feet in Nepalese population by using radiographs, to determine the number of the sesamoid bones of the foot and hand, commonest site of occurrence and to correlate the findings between gender and age. Methodology: This prospective quantitative study was performed in the Department of Radiology and Imaging, TUTH. The radiographs of foot and hand were reviewed to evaluate the presence or absence of sesamoid bones and patient demographics were also noted. Data collection was done for a period of three months and random probability sampling method was used. Results: This study resulted that in foot radiographs, the most common sites of sesamoid bones was first metatarsophalangeal joint (1st MTPJ) where two sesamoid bones were found, whereas single sesamoid bone was found in other sites. The percentage of sesamoid bones in first interphalangeal joint (1st IPJ), second metatarsophalangeal joint (2nd MTPJ), third metatarsophalangeal joint (3rd MTPJ), fourth metatarsophalangeal joint (4th MTPJ) and fifth metatarsophalangeal joint (5th MTPJ) were 7.9%, 15.4%, 0 %, 0.4%, and 26.7% respectively. The number of sesamoid bones ranged from 2- 5 in single foot with frequency of occurrence of 2 bones being highest (58.3%). The percentage of sesamoid bones in foot was found to be relatively higher in female than male. In the analysis of hand radiographs, the most common sites of sesamoid bones was 1st MCPJ ( single sesamoid bone in 80.33% and a pair of sesamoid bones in 19.67% ) .The percentage of sesamoid bones in 1st IPJ, 2nd MCPJ, 3rd MCPJ, 4th MCPJ and 5th MCPJ were 37.33%, 58.67% ,5.33% , 5.33% and 59.33% respectively. The number of sesamoid bones ranged from 1 - 6 in single hand with frequency of occurrence of 3 bones being higher (32%). The percentage of sesamoid bones in hand was relatively higher in male than female. Conclusion: The distribution and frequency of sesamoid bones differ according to sites, gender and age. This study improves the knowledge on distribution of sesamoid bones of the foot and hand and also provides anatomical data that could help clinicians in diagnosis and management of various sesamoid bone disorders in patients who present with pain and discomfort in the foot and hand.
