Hallux, sesamoid, and first metatarsal injuries are common foot injuries and have implications in the biomechanical functionality of the first ray and foot. They are essential for propulsion in normal gait. As part of the first ray, it is an important contributor to normal locomotion. Any structure disruption or injury can create angular changes or arthritis, which can have biomechanical implications, including pain, disability, compensation, swelling, and reduced range of motion.

All forms of dance are highly demanding activities, with a lifetime injury incidence of up to 90%. Most dance types are stressful, particularly on the dancer's forefoot, but certainly there is no area of the foot or ankle that is exempt from potential injury. ⋯ A thorough understanding of these movements guides the physician to the cause of the injury, particularly in understanding specific overuse injuries. This article discusses biomechanics of the foot and the imaging and treatment of dance-related injuries.

Review Case ReportsPrimary subtalar joint arthrodesis with internal and external fixation for the repair of a diabetic comminuted calcaneal fracture.
Comminuted, intra-articular calcaneal fractures can cause severe lower extremity impairment and have devastating effects on a patient's well being. Diabetes is a multisystem process that may cause neuropathy and loss of protective sensation further complicating the prognosis. Not all calcaneal fractures are created equal and when considering the patient's overall presentation and extent of injury, the combined approach of internal and external fixation for fracture reduction may be beneficial for restoration of anatomic alignment and function.

The Lisfranc joint encompasses 6 articulations, weak dorsal ligaments, and strong plantar ligaments. The Lisfranc ligament serves to secure the second metatarsal in the keystone of the midfoot. Traumatic ligament injury and fracture can result in deformity, instability, pain, and degenerative joint disease of the Lisfranc joint. ⋯ Open reduction with internal fixation (ORIF) demands accurate anatomic alignment to prevent the need for salvage arthrodesis. Early studies have shown that primary arthrodesis of the medial 3 rays has performed equally well or better than ORIF for the displaced primarily ligamentous and severe injuries. A paradigm shift may emerge as more studies favor primary arthrodesis.

Case ReportsJuxta-articular osteoid osteoma of the talar neck: a case report.
Juxta-articular osteoid osteomas of the ankle are rare and tend to have an atypical presentation. Because of the proximity to the joint, patients experience symptoms that may delay or mislead the diagnosis. ⋯ Surgical excision of the lesion was performed with excellent results. Juxta-articular osteoid osteomas should be considered in the differential diagnosis of persistent ankle pain in teenagers and young adults who do not respond to treatment directed at more common conditions.
