“…Sbs can be found in all the fingers, but it is most common in the MCP joint of the thumb. The current study aimed to determine the presence of Sbs ossification at the thumb MCP joint of the hand, which has been confirmed in almost all individuals (98.2%-100%) by several studies 1 , 2 , 3 , 4 , 8 , 9 , 10 , 11 , separately for girls and boys, and its relationship with puberty period.…”

“…While the sesamoids of the thumb MCP joint are considered a normal skeleton part of adult humans, sesamoids of other fingers may differ 3 , 10 , 12 . Several studies in the literature have found that all adults have Sb at the thumb MCP joint 1 , 2 , 3 , 4 , 8 , 9 , 10 , 11 . Yammine 2 reported a 99.93% prevalence of Sbs on the radial side and a 99.81% prevalence on the ulnar side in a meta-analysis.…”

“…A meta-analysis published in 2014 revealed that ethnicity and heredity influence the distribution of Sbs among individuals 2 . Although the location of Sbs in the hand varies from person to person, the metacarpophalangeal (MCP) joint is the most common location, with a reported incidence of 100% 1 , 3 , 4 . Although it is known that it can be seen on all fingers, the most common variation has five Sbs in the hand 6 , 7 .…”

Objective: The current study aimed to determine the onset of sesamoid bones (Sbs) ossification at the thumb metacarpophalangeal (MCP) joint of the hand and its relationship with puberty. Methods: This retrospective radiographic study included patients aged 5-17 years. The presence of Sbs was investigated separately for each age group. Patients were classified based on their age, gender, and the presence of radial and ulnar sesamoids. Results: A total of 1,020 radiographs from 939 patients were analyzed. Sbs began to ossify in girls at the age of 8 years and in boys at the age of 9 years. The ulnar-radial sesamoids were present in all individuals in the same age group at the age of 13-14 years in girls and 15 years in boys. The age at which 50% of the individuals in the same age group had a sesamoid was 10.4 years in girls and 11.9 years in boys on the radial side, 9.5 years in girls, and 11.5 years in boys on the ulnar side. Conclusions: In all individuals, the time between the onset of sesamoids of the MCP joint and development corresponds to the physiological period of puberty. However, the age at which puberty begins coincides with the time when Sbs begin to ossify in 50% of both sexes in the same age group.

“…Double sesamoids are frequently found in the first MCP joints 2 . However, single sesamoid is seen in the other MCP joints and the thumb interphalangeal (IP) joint 3–7 . Few studies have observed sesamoids in proximal interphalangeal (PIP) joint of middle, ring and little fingers 8 .…”

ObjectivesThe position of sesamoid of thumb metacarpophalangeal (MCP) joint changed clearly when the joint was dislocated dorsally. However, the significance of sesamoid location in diagnosing joint dislocation was unclear. The present study aimed to explore the positional relationship between sesamoid bone and thumb metacarpophalangeal joint in normal and dorsal dislocation joints.MethodsBetween January 2018 and August 2023, we collected 60 isometric plain films from sixty outpatients and reviewed 56 anisometric plain films from twenty‐eight emergency patients with dorsal dislocation of thumb MCP joint at Tianjin Hospital, then took measurements on the hand X‐ray images. The sesamoid length on its longitudinal axis was defined as DP, the distance between the distal edge of sesamoid and thumb MCP joint was defined as DJ, and the ratio of DJ and DP was R. An independent‐samples t‐test and paired‐samples t‐test was utilized to analyze difference among data groups.ResultsThe 60 isometric images were from 30 male and 30 female outpatients with normal bone structure in their hands, and the 56 anisometric images of the 28 emergency patients included both preoperative and postoperative materials. Among the outpatients, the actual distance between the distal edge of sesamoid and thumb MCP joint space (DJ) was 2.09 mm and 1.40 mm in males and females, respectively. The authentic average length of sesamoid (DP) was 4.46 mm in males and 4.22 mm in females. The average value of R (the ratio of DJ and DP) in males and females was 0.49 and 0.34, respectively. There were gender‐related statistical differences in DJ (p < 0.01) and R (p=0.01), but no statistical difference in DP (p > 0.05). For the 28 emergency patients, the mean value of R was –0.47 before joint reduction and 0.58 after joint reduction, with statistical difference between them (p < 0.01).ConclusionsThere was significant difference in the relative position between sesamoid and thumb MCP joint when joint dislocation and joint reduction. The distal edge of sesamoid beyond thumb MCP joint could be an evidence in diagnosing joint dorsal dislocation. The distal edge of sesamoid below thumb MCP joint could be an evidence of joint reduction.

Purpose: This study aimed to retrospectively examine the accessory ossicles and sesamoid bones of the patients who applied to the emergency department with any hand and wrist complaints, on radiological images according to gender, frequency of incidence and extremity side. Materials and Methods: This retrospective study was performed on radiological images (digital x-ray) of 500 patients (297 men, 203 women). Presence, prevalence, coexistence and distribution of accessory ossicles and sesamoids in the hand of patients without hand skeletal deformities were retrospectively analyzed. Results: Accessory ossicles were detected in 8 (1.6%) of 500 cases. In our study, all of the accessory ossicles seen in the wrist and the hand region were ulnar styloid ossicles. Sesamoid bone was detected in 500 cases (100%) in metacarpophalangeal I (MCP I), in 192 cases (38.4%) in metacarpophalangeal II (MCP II), in 17 cases (3.4%) in metacarpophalangeal III (MCP III), in 2 cases (0.4%) in metacarpophalangeal IV (MCP IV), and in 34 cases (6.8%) in metacarpophalangeal V (MCP V). Conclusion: This study will contribute to the literature in terms of Turkish population incidence by using digital x-ray images for hand sesamoid bones and accessory ossicles.
