The Lapidus procedure affords correction of a multitude of first ray pathologic entities. When reconstructing the first ray using the Lapidus procedure, the relocation of the first metatarsal over the sesamoid bones with frontal plane rotation should be considered one of the key components. In the present technical report, we have described a bunion correction with emphasis on sesamoid reductio...

The hallucal interphalangeal sesamoid bone is usually asymptomatic, but it is not uncommon for it to be symptomatic in cases of undue pressure, overuse, or trauma. Even in symptomatic cases, however, patients often suffer for extended periods due to misdiagnosis, resulting in depression and anxiety that can steadily worsen to the extent that symptoms are sometimes mistaken for a somatoform diso...

A fracture of the sesamoid bone of the hand is rarely seen. In most cases, it is strictly associated with the trauma. The patient complains of a long-lasting, due to unclear diagnosis, painful swelling of the joint with an inability to flex the affected finger. Limited blood supply makes the untreated fracture prone to avascular necrosis. Thus, it is extremely important to make a proper diagnos...

The sesamoid complex is located centrally and plantar to the first metatarsal head, where they are imbedded within the plantar plate, which transmits 50% of body weight and more than 300% during push-off, is susceptible to numerous pathologies. These pathologies include sesamoiditis, stress fracture, avascular necrosis, osteochondral fractures, and chondromalacia, and are secondary to these lar...

Over the past few decades, the development of magnetic resonance imaging (MRI) for the diagnosis of equine lameness has revolutionized our understanding of what used to be termed ‘navicular disease’. Prior to MRI, navicular disease was diagnosed primarily by a positive response to palmar digital nerve blocks (PDNB) and identification of characteristic radiological findings; particularly changes...

OBJECTIVE To evaluate the correction of the intermetatarsal angle after arthrodesis of the metatarsophalangeal joint of the hallux. We believe that varus deformity of the first metatarsal can be corrected after arthrodesis of the first metatarsophalangeal joint, without the need for proximal osteotomy. METHODS Forty-three feet of patients who had undergone arthrodesis of the first metatarsoph...

ANATOMY: The medial collateral ligament (MCL) is one of four major ligaments that supports the knee and is the primary static stabilizer against valgus rotation of the joint. It consists of two components, the superficial (sMCL) and deep MCL (dMCL). The sMCL has one femoral and two tibial attachments. The femoral attachment is situated on the medial epicondyle. The proximal attachment blends in...

The authors describe an extremely rare case of traumatic fracture both hallux sesamoid bones, which was treated non-surgically, and the indications, contraindications, unfavorable outcomes analyzed. Level Evidence V; Therapeutic Studies; Expert Opinion.
