Cuboid fractures

Stress fractures are a consequence of repeated submaximal loads with inadequate time for recovery and biologic repair or remodelling. The foot and ankle complex (FAC) represents a common site for development of stress fractures. Whilst the overall incidence of stress fractures is low, they are prevalent in athletes and military personnel causing significant time away from sports or work. Within these populations, certain stress fractures directly correlate to specific activities. Factors that commonly influence these fractures include an acute increase in new repetitive physical activity combined with muscle fatigue, training errors or improper athletic techniques, which challenge the regenerative and remodelling capacity of bone...

Introduction: The purpose of this study was to compare the changes in foot at different sole-ground contact angles during forefoot running.

Methods: A male participant of Chinese ethnicity was enlisted for the present study, with a recorded age of 25 years, a height of 183 cm, and a body weight of 80 kg. This study focused on forefoot strike patterns through FE analysis...

A serious kind of fractured foot ailment is a foot crush injury. Foot injury commonly happens in accidents involving transportation or the workplace, such as automobile accidents, big objects falling on the foot, or heavy machinery running over the foot. Foot crush injuries are more severe than regular foot fractures. These wounds are usually very serious, involving many fractures and soft tissue injuries. The main symptoms include pain, severe muscle and tissue damage, and extreme swelling. Because of this, treating a foot crush injury can be quite challenging and frequently requires the collaboration of physical therapists, orthopedic surgeons, and podiatrists...

Porous biphasic calcium phosphate (BCP) ceramics are widely used in bone tissue engineering, and the mechanical properties of BCP implants must be reliable. However, the effects of pore structure (e.g., shape and size) on the mechanical properties are not well understood. In this study, we used molecular dynamics simulations to investigate the influence of pore shape and size on the mechanical behavior of BCP nanoparticles. BCP void models with cylindrical and cuboid pores ranging from 2 to 16 nm in diameter were constructed, and the elastic moduli were calculated...

Multiple cuneiform fractures combined with isolated intermediate cuneiform dorsal dislocation and cuboid fracture, with disruption of the Lisfranc ligament, are rare injuries. In this study, we present a polytrauma patient who sustained these injuries, his treatment course, and the follow-up period. The patient was operated on the day of the injury and six months after that the results are very satisfactory.

The os peroneum is an accessory ossicle located along the lateral aspect of the cuboid bone. Its position can serve as an indicator of peroneus longus tendon (PLT) injury. Imaging studies including radiographs and MRI can help detect malposition of the os peroneum and progressive injuries to the PLT and its associated structures. We report a case of a woman with recurrent foot and ankle pain, demonstrating progressive retraction of the os peroneum, implying severe PLT injury which may have ultimately predisposed her to a traumatic fifth metatarsal base fracture...

Cuboid dislocations are a rare type of injury with few cases reported. A 41-year-old female came in for an assessment of her left foot, seeking evaluation 13 days post-injury. On inspection of the left lower extremity, we found swelling and ecchymosis throughout the midfoot. There was dimpling along the fourth/fifth tarsometatarsal (TMT) joint with palpable dorsal subluxation. A closed cuboid reduction with percutaneous pinning was performed 20 days after the initial injury. The cuboid was reduced with a combination of traction and direct pressure...

CASE: A 28-year-old woman with no medical history involved in a motor vehicle collision presented with deformity of the right leg and traumatic right heel pad avulsion. Radiographs demonstrated a right foot mid-tarsal fracture-dislocation, open cuboid, closed right tibia, and segmental fibula fractures. The heel pad was repaired using polydioxanone suture in a quilted technique with sterile buttons. At 1-year follow-up, the patient's heel pad was well-fixed with intact sensation and no pain...

Metatarsal bone fractures are one of the most frequent foot injuries, especially after motor vehicle accidents in children. This case report briefly demonstrated a rare instance of pediatric all-metatarsal fractures of the left foot in an adolescent patient with polytrauma after a motorcycle accident. This case report illustrated the surgical procedure's potential for healing pediatric foot fractures in teenage patients after polytrauma. In the examination of a 16-year-old male patient brought to the emergency department after a motorcycle accident, we detected a right foot third finger proximal phalanx open fracture, right foot fourth finger proximal phalanx fracture, left foot first metatarsal proximal fracture, left foot second, third, fourth, and fifth metatarsal distal fractures, left foot cuboid, and navicular bone fractures...

BACKGROUND: Bleeding in the pelvis can lead to a circulatory problem. The widely used whole-body computed tomography (WBCT) scan in the context of treatment in the trauma resuscitation unit (TRU) can give an idea of the source of bleeding (arterial vs. venous/osseous); however, the volume determination of an intrapelvic hematoma by volumetric planimetry cannot be used for a quick estimation of the blood loss. Simplified measurement techniques using geometric models should be used to estimate the extent of bleeding complications...

OBJECTIVE: The aim of this review was to determine operative indications for Lisfranc injuries. METHODS: A systematic review using a MEDLINE literature search was performed using the index "Lisfranc Injury" from 1980 onward using PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analysis) guidelines where applicable. Inclusion criteria were all clinical studies reporting on the management of Lisfranc injuries obtained via the search index, including case reports, review articles, cohort studies, and randomized trials...

OBJECTIVE: To compare clinical efficacy of No-touch technique and traditional retractor in treating calcaneal fracture. METHODS: Clinical data of 74 calcaneal fracture patients with closed Sanders typeⅡ to Ⅳ were retrospectively analyzed from July 2019 to June 2021. According to different treatment methods, the patients were divided into No-touch group and conventional group, 37 patinets in each group. In No-touch group, there were 25 males and 12 females, aged from 19 to 70 years old with an average of (42...

Highly nanocrystalline carbonated hydroxyapatite (CHAp) is synthesized by hydrothermal technique with four different stoichiometric compositions for microstructural and mechanical analysis. HAp is one of the most biocompatible material and addition of carbonate ions lead to increase in fracture toughness highly required in biomedical applications. The structural properties and its purity as single phase is confirmed by X-ray diffraction. Lattice imperfections and structural defects is investigated using XRD pattern model simulation, i...

BACKGROUND: To assess whether delaying operative fixation through the sinus tarsi approach resulted in a decreased wound complications rate or could hinder the quality of reduction in subjects with Sanders type II and III displaced intra-articular calcaneus fractures. METHODS: From January 2015 to December 2019, all polytrauma patients were screened for eligibility. We divided patients into two groups: Group A, treated within 21 days after injury; Group B, treated more than 21 days after injury...

Methotrexate is associated with bone lesions that are rare and, although presenting with a typical localisation to the lower extremities and appearing with a characteristic radiologic morphology, largely unknown and often misdiagnosed as osteoporotic insufficiency fractures. The correct and early diagnosis, however, is key for treatment and prevention of further osteopathology. Here, we present a patient with rheumatoid arthritis who developed multiple painful insufficiency fractures in the left foot (processus anterior calcanei, tuber calcanei) and in the right lower leg and foot (anterior and dorsal calcaneus and at the cuboid and distal tibia) during therapy with methotrexate, which were all misdiagnosed as osteoporotic...

Injuries with exposure of soft tissue are frequent in orthopaedics. Innovative therapies using prosthesis as an auxiliary material to treat this type of injury are under development, aiming to overcome applicability and execution limitations of myocutaneous flap techniques. Figueiredo's technique uses a polypropylene prosthesis extracted from sterile saline to treat trauma at the fingertip. It is an alternative technique with a high success rate, reproducible, low cost and easy to apply. This article reports a case of foot injury with exposure of soft tissue treated with a treatment similar to Figueiredo's technique...

With the emphasis on collagen and hydroxyapatite, the main structural components of bone tissue, synthetic grafts fall short of matching the clinical efficacy of autologous bone grafts. Excluded non-collagenous protein (NCPs) and carbohydrates also participate in critical cell signaling cascades and guide mineral deposition during intermediate stages of bone healing. By mimicking the native fracture repair process, polymeric scaffolds that incorporate calcium-binding moieties present in fibrocartilage can potentially enhance their bioactivity, mineralization, and bone growth...
