Isolated talonavicular dislocations are uncommon injuries, usually occurring as a result of high-energy trauma. As a result extensive disruption of the midfoot ligamentous structures commonly occur with these injuries, often resulting in a poor outcome. Due to its rarity these injuries remain poorly understood, and several opinions exist on the probable mechanisms of injury and the optimal treatment. Five main injury types have been classified based on the deforming forces and direction of displacement; medial, lateral, longitudinal, plantar, and crush. However new mechanisms and injury patterns continue to be reported. We report a case of a medial swivel type talonavicular dislocation, associated with a cuboid body fracture, which is previously undescribed.

Article Synopsis
- Talus fractures and subtalar dislocations in children are extremely rare, making up only a small percentage of pediatric injuries, emphasizing the uniqueness of such cases.
- A case study involving a 14-year-old with a medial subtalar dislocation and a Hawkins stage III talar neck fracture was successfully treated using the Bootjack Technique, with the patient recovering fully after immobilization and physiotherapy.
- Despite limited documented cases, it's important for medical professionals to recognize these injuries due to potential complications, highlighting that orthopedic treatment can be a safe and effective management option for young patients.

Article Synopsis
- The talonavicular joint (TNJ) dislocation happens when two bones, the talus and navicular, lose their connection completely, mostly due to injuries.
- Medial dislocations are more common, while lateral dislocations often come with fractures in another joint called the calcaneocuboid.
- A case study talks about a six-month-old TNJ dislocation that needed surgery to fix it, and afterward, the patient had no more pain.
A Rare Case of a Medial Peritalar Dislocation on a Rock Climber.

Article Synopsis
- Peritalar dislocations are rare foot injuries that involve dislocations of specific foot joints, primarily occurring in sports, with no previous reports found in rock climbers.
- A case study describes a 38-year-old climber who sustained a medial peritalar dislocation from a climbing accident, which was successfully treated with non-operative methods after a closed reduction in the emergency room.
- Timely closed reduction is crucial to prevent complications, and thorough radiological evaluations are essential to check for other fractures and assess the injury’s impact on recovery and function.
Postoperative Calcaneocuboid Joint Subluxation and Midtarsal Joint Changes in Pediatric Idiopathic Flexible Flatfoot Treated With Calcaneal Lengthening Osteotomy: A Midterm Follow-up Study.

Background: Calcaneal lengthening osteotomy (CLO) is one of the main surgical options for treatment of pediatric idiopathic flexible flatfoot (FFF). Reportedly, calcaneocuboid (CC) joint subluxation occurs after CLO; however, its effect on the midfoot remains unclear. This study aimed to investigate the radiologic midterm results after CLO treatment in pediatric idiopathic FFF.

Unlabelled: Subtalar dislocations of the talonavicular and talocalcaneal joints are rare, accounting for approximately one percent of all dislocations.1 These dislocations are typically the result of a high energy mechanism and present a challenge during reduction attempts. We present the case of a male in his early 20's who presented to the emergency department after a motorcycle accident with right foot and ankle pain and obvious deformity.
