Christelle Le Roux, Ann Carstens
Axial sesamoiditis or osteitis of the proximal sesamoid bones (PSBs) in the horse is described as a rare condition. The cause remains unknown and speculative, with vascular, infectious, and traumatic aetiologies implicated. It is specifically associated with injury of the palmar or plantar ligament (PL), also known as the intersesamoidean ligament. Imaging findings are generally rewarding and radiological changes are typical, if not pathognomonic, for the condition. Lesions consist of bone lysis at the apical to mid-body axial margins of the PSBs, with variable degrees of joint effusion...

Tendon/ligament mineralization is recognized in horses but information regarding its clinical significance is limited. The aims of this observational study were to report the structures most commonly affected by ultrasonographically detectable mineralization and, for these, determine frequency of diagnosis and key clinical features. Cases presented at our hospital in April 1999-April 2013 and September 2014-November 2015 were included: a total of 27 horses (22 retrospective, five prospective). Mineralizations were most common in deep digital flexor tendons (10) and suspensory ligament branches (eight), representing 10% and 7% (estimated), respectively, of horses diagnosed with injuries to these structures during the study...

BACKGROUND: Fracture of the proximal sesamoid bones continues to be the most common fatal musculoskeletal injury in US racehorses. Identifying factors that influence fracture risk could lead to screening techniques to reduce catastrophic injury rates and improve animal welfare. OBJECTIVES: To identify morphological differences between proximal sesamoid bones of the contralateral limb of fracture and control horses and assess the feasibility of computed tomography (CT) to detect traits associated with proximal sesamoid bone fracture...

Postoperative recurrence of hallux valgus is a relatively common complication and is associated with unsatisfactory surgical outcomes. Risk factors for postoperative recurrence include a round lateral edge of the first metatarsal head (a positive round sign) and incomplete reduction of the sesamoids. These risk factors may relate to residual pronation of the first metatarsal following surgery. A novel technique of a proximal supination osteotomy, in which varus and pronation of the first metatarsal can be corrected simultaneously, can achieve significant correction in moderate or severe hallux valgus deformity and a low rate of hallux valgus recurrence...

Many different surgeries have been proposed for hallux valgus treatment, osteotomies being the currently recommended ones. Because of high recurrence rates, distal, diaphyseal and proximal osteotomies have been used to improve alignment and sesamoid reduction. The center of rotation of angulation (CORA) concept applies to any deformity and helps to completely realign 2 bone segments. When used with proximal osteotomies, bone displacement and angulation is performed obtaining complete deformity correction. The proximal oblique sliding closing wedge (POSCOW) osteotomy follows the CORA concept and permits preoperative planning...

Jin Su Kim, Ki Won Young
Hallux valgus (HV) is not a simple two-dimensional deformity but is instead a three-dimensional deformity that is closely linked to sesamoid position and first metatarsal (MT) pronation. HV may or may not be accompanied by sesamoid subluxation and/or first MT head pronation. Each of these scenarios should be assessed using weighted computed tomography scan preoperatively, and the necessary corrections should be performed accordingly.

Radio-opaque formations behind the spinous processes of the cervical spine are really rare. They were described in 1929 for the first time. Sesamoid ossicles are found close to a bone or a joint and are usually small. Some sesamoids form part of normal human anatomy, while others are normal anatomical variants. We report a case of a 73-year-old Caucasian male who visited the outpatient clinic complaining about chronic cervical pain. An oblong sesamoid accidentally discovered during routine anteroposterior (AP) and lateral x-ray, within the nuchal ligament (NL) at the C3-C6 spinous processes level...

The fabella is a kind of sesamoid bone which is located in the lateral head of the gastrocnemius muscle. A slice of studies demonstrated that fabella is involved in the knee joint stabilization. Fabella fracture may cause knee pain or functional impairment as the previous reports pointed. It is extremely rare, which leads to its high rate of missed diagnosis in clinical and radiography to some extent. We report a case of a 38-year-old female who was struck by an electromobile. The fabella fracture was confirmed on X-ray plain films...

Distal Chevron osteotomy is a well-established surgical procedure for mild to moderate hallux valgus deformity. Many methods have been described for fixation of osteotomy site; secure fixation, enabling large displacement of the metatarsal head, is one of the essentials of this procedure. The purpose of the present study was to evaluate the short-term radiographic outcome of a distal Chevron osteotomy using an intramedullary plate for the correction of hallux valgus deformity. The present study evaluated 37 patients (40 feet) who underwent distal Chevron osteotomy using an intramedullary plate by periodic radiographs obtained preoperatively and at 4 weeks, 8 weeks, 3 months, and 6 months postoperatively...

Arthroscopic treatments for the first metatarsophalangeal joint have not spread fully owing to a number of factors. First, in the common arthroscopic view, the joint is observed from above, which makes the structures difficult to grasp and the dorsal aspect of the joint difficult to visualize and treat. Second, techniques for widening the view have not yet been reported. Third, the portals necessary for observation and treatment with hallux sesamoids have not yet been established. Finally, techniques for detecting the sesamoids have not been previously reported...
