Sesamoid Bones

Sesamoid bones and accessory ossicles are common incidental findings on radiographs. These can occasionally become symptomatic, usually after a precipitating event such as an injury or overuse, or they can be incidental findings unrelated to the presenting pathology. The aim of this study was to highlight a rare case of a bipartite fifth metatarsal sesamoid bone and to review previous literature regarding sesamoid bones and accessory ossicles.

Abstract Objective. To study the correlative between the sesamoid bones under the head of the first metatarsal and the development of hallux valgus determined with radiographs.Methods.The measurements were performed on the X-ray of 300 normal feet and 300 cases of hallux valgus. The following parameters were measured: hallux valgus angle(HVA); the first-second intermetatarsal angle(IMA) between the axes of the first and second metatarsal;the length of the second metatarsal（CD）;the position of tibial sesamoid(TSP ) measured the percent formed between the tibial sesamoid and the centreline of the first metatarsal;the position of fibular sesamoid(FSP) measured tangent value between fibular sesamoid bone and lateral cortex of first metatarsal bone ; the absolute distances (AB) from the centre of the tibial sesamoid to the long axis of the second metatarsal, the absolute distances (EF) from the centre of the fibular sesamoid to the long axis of the second metatarsal and the absolute distance (GH) from the centre of the tibial sesamoid to the centre of the fibular sesamoid. Then calculate the ratio of AB to CD (K1), EF to CD (K2) and GH to CD (K3). Results.HVA moderately positively correlates with TSP and moderately negatively correlates with FSP in subjects with HVA ≥ 20°. HVA and FSP are strongly negatively correlated in the hallux valgus group. Conclusion.The dislocation of sesamoid bone under the first metatarsal head is an important pathological factor leading to valgus. HVA is positively correlated with TSP and negatively correlated with FSP.

Sesamoid Bones

The three-dimensional anatomy of the ostrich (Struthio camelus) knee (femorotibial, femorofibular, and femoropatellar) joint has scarcely been studied, and could elucidate certain mechanobiological properties of sesamoid bones. The adult ostrich is unique in that it has double patellae, while another similar ratite bird, the emu, has none. Understanding why these patellae form and what purpose they may serve is dually important for future studies on ratites as well as understanding mechanobiological characteristics of sesamoid bone development. For this purpose, we present a three-dimensional anatomical study of the ostrich knee joint, detailing osteology, ligaments and menisci, and myology. We have identified seven muscles which connect to the two patellae and compare our findings to past descriptions. These descriptions can be used to further study the biomechanical loading and implications of the double patella in the ostrich.

History Of

Pancreatic haemangiomas are benign vascular tumours very rare in adults. Twenty-two cases are described in the literature. The symptoms are non-specific, and therefore rarely clinically suspected, and the vast majority are incidental findings in imaging tests such as ultrasound, CT, angiography or MRI. They appear on CT as a cystic lesion with contrast enhancement in the arterial phase. We present the case of a 36-year-old male patient with no history of disease, referred with lumbar pain and suspected renal calculus after tomography showing hypervascular enhancement in the pancreatic body and infiltrative lesion (possible neuroendocrine neoplasia) on MRI and biliopancreatic echoendoscopy. He was submitted to laparotomy with subtotal pancreatectomy and splenectomy and satisfactory evolution.

SummaryObjectives: To describe a technique for arthroscopy of the fetlock joint of the dromedary camel, and the problems that could occur during and after arthroscopy.Methods: Seven animals (4 cadaveric limbs and 3 living camels) were used in this study. Two dorsal arthroscopic portals (lateral and medial) and one palmaro-lateral portal were used. Distension of the joint capsule was effected by injecting Ringer's lactate solution into the joint cavity. Landmarks for the dorsal arthroscopic portals were located at the centre of the groove bounded by the lateral branch of the suspensory ligament and the large metacarpus at a point 1 cm proximal to the joint. The palmaro-lateral portal was located in a triangular area between the branch of the suspensory ligament, the large metacarpus, and the sesamoid bone, with insertion of the arthroscope in a 45° joint flexion angle.Results: Arthroscopy of the fetlock joint via the dorso-lateral portal allowed examination of the distal end of the large metacarpus and the proximal end of the first phalanx of the fourth digit. Arthroscopy via a dorso-medial approach allowed examination of the distal end of the large metacarpus and the proximal end of the first phalanx and the distal end of the third digit. The palmaro-lateral portal allowed examination of the sesamoid bones, the synovial membrane, and the synovial villi. The main complications recorded during arthroscopy were iatrogenic articular surface injury as well as obstruction of vision with the synovial villi.Clinical significance: This is the first work to describe the normal arthroscopy of the fetlock joint in the dromedary camel, the arthroscopic portals, and the complications that could occur during and after arthroscopy. Further studies are required for diagnosis of pathological changes in the fetlock joint of the dromedary camel and for arthroscopy of other joints in the dromedary camel.

The purpose of this study was to examine the plain AP radiograph of foot and lateral radiograph of knee in order to determine the prevalence and size of sesamoid bone in different part of foot and on the posterior aspect of the knee joint. A cross-sectional study was performed in Department of Radiology and Imaging, Tribhuvan University Teaching Hospital from July to September 2014. A total of 206 radiographs of foot (55) and knee (155) were collected. 121 (58.7%) were female and 85 (41.3%) were male. The most common site of sesamoid bone in foot was in the first metatarsal joint (96.4%) whereas the sesamoid bone in knee joint, fabella was found in 12.3% of total cases. The prevalence is more common in female than in male. The length and breadth of the sesamoid bones were measured and then area of bones was calculated. The size of medial and lateral sesamoid bone in the first MTP Joint was measured 0.6225 cm2 and 0.8261 cm2 respectively. The mean size of sesamoid bone of knee, fabella was 0.2818 cm2.
