Cuboid fractures

A 35-year old healthy male trauma surgery chief resident, suffered a high-speed motor vehicle collision. The patient sustained the following injuries: a Gustilo-Anderson grade 2 open comminuted intra-articular fracture of the left distal femur (AO 33C3.3), a Hawkins 1A neck fracture of the right talus (AO 81.2A), an undisplaced Lisfranc injury of the right foot comprising avulsion fractures at the base of the 1st, 2nd and 5th metatarsal as well as the cuboid bone suggesting ligament injury and 2nd to 5th carpometacarpal dislocations of the right (non-dominant) hand with comminuted fractures of the capitate, hamate, trapezoid and the base of the fifth metacarpal bone...

Fracture-dislocations of the midfoot are relatively rare injuries. We present a case of a 20-year-old man presenting with navicular-cuneiform and calcaneal-cuboid fracture-dislocation of his right foot due to a crush injury during work. The patient's injury was treated by open reduction internal fixation.

OBJECTIVES: To investigate injury patterns and long-term outcomes of mid-tarsal (Chopart) injuries in a sizeable number of patients. DESIGN: Prospective study. SETTING: Level-1 Trauma Center. PATIENTS: One-hundred and twenty-two patients (average age 37.6 years) with 128 Chopart injuries over a 15-year period, 27% of which were polytraumatized. In 47% more than one of the 4 bones of the mid-tarsal joint was fractured...

Lisfranc injuries present a challenge due to their ubiquity though frequent missed diagnoses. A paucity of data exists associating the contribution of bone density to injury type. This investigation compares the regional bone density between Lisfranc injury types using computed-tomography (CT)-derived Hounsfield units. A retrospective chart review identified patients with gross ligamentous and avulsion-type Lisfranc injuries determined by CT examination of the second metatarsal base and medial cuneiform. Regional bone density was assessed by averaging the Hounsfield units of the first metatarsal base, navicular, cuboid, calcaneus, and talus between 2 reviewers...

The purpose of this case report is to raise awareness of an extremely rare cause of limping, in young children. Clinicians should have a high index of suspicion of a possible cuboid fracture when evaluating a young child who presents with limping.

BACKGROUND: This study aims to analyze the ligaments of the dorso-lateral calcaneo-cuboid joint and to assess the biomechanical relevance of the bifurcate ligament. METHODS: 16 specimens were analyzed for their ligamentous anatomy of the dorso-lateral calcaneo-cuboid joint and side-alternating assigned to two groups with varying ligamentous dissection order. The Chopart joint was stressed in plantar, medial, and lateral direction measuring the displacement by an 3D motion tracker for every dissection step...

Previous research has reported that up to 92% of injuries amongst badminton players consist of lower limb, whereby 35% of foot fractures occurred at the metatarsal bone. In sports, insoles are widely used to increase athletes' performance and prevent many injuries. However, there is still a lack of badminton insole analysis and improvements. Therefore, this study aimed to biomechanically analyse three different insole designs. A validated and converged three-dimensional (3D) finite element model of ankle-foot complex was developed, which consisted of the skin, talus, calcaneus, navicular, three cuneiform, cuboid, five metatarsals and five phalanges...

BACKGROUND: Complete isolated calcaneal dislocation, defined as dislocation of talocalcaneal and calcaneocuboid joints with intact talonavicular joint without significant fracture, is an exceedingly rare injury. CASE PRESENTATION: A 49-year-old man, after a motor vehicle collision, presented with a closed isolated anterolateral dislocation of the calcaneus associated with fracture of the sustentaculum tali, cuboid, lateral process of the talus, and avulsion fracture of superior peroneal retinaculum...

Introduction: Subtalar dislocations are rare injuries, representing around 1% of all dislocations. Defined as talonavicular and talocalcaneal separation, occurs in medial, lateral, anterior, or posterior direction. They are more common in young men, usually as a result of high energy trauma and are associated with posttraumatic arthritis, especially when accompanied with peritalar fracture (a cuboid fracture in this case), so prompt recognition is necessary in order all these complications to be avoided...

BACKGROUND: Multiple case reports of fifth metatarsal (MT) intramedullary fixation highlight symptomatic hardware with screw head impingement on the cuboid. We developed a fifth MT intramedullary screw trajectory model using weightbearing computed tomography data. The goal was to assess for cuboid impingement with simulated intramedullary screw position. METHODS: For 20 weightbearing foot computed tomographs (CTs), an automated tool was used to simulate fifth MT screw fixation in the ideal trajectory down the shaft and with a 7-mm screw head...

The extended lateral side approach is a common technique in the surgical treatment of calcaneal fractures, with thalamic collapse offering a good exposure of the fractured site; however, it can be burdened with complications due to soft tissue trauma. The present study aimed to compare patients treated with minimally invasive osteosynthesis through a minimum lateral approach and internal fixation with patients that were treated using internal fixation with an extended lateral side approach in cases of intra-articular calcaneal fractures with thalamic fracture...

Zr-doped In2 O3 thin films are prepared on FTO substrates by a two-step method: firstly, Zr-doped In(OH)3 thin films are hydrothermally deposited, and then converted to Zr-doped In2 O3 films by heat treatment. It is found that during the phase transition from Zr-doped In(OH)3 to Zr-doped In2 O3 , the cuboid-like crystal grains will fragment, resulting in a large number of new surfaces and cracks. Zr doping can introduce shallow impurity levels in the band gap of In2 O3 , which will enhance the absorption of incident light...

Clear recommendations about the optimal treatment of traumatic tarsal navicular fractures are still very debated in the literature, and this is due to several factors: navicular fractures are rare and often misdiagnosed injuries, they are frequently associated with other fractures or a dislocation of the midfoot, and the current knowledge is based on few papers mainly considering a limited number of cases and dealing with different therapeutic approaches. The treatment of navicular body fractures is controversial and burdened by a high incidence of complications; in particular, Sangeorzan type III comminuted fractures represent a real challenge for the orthopedic surgeon...

INTRODUCTION AND IMPORTANCE: Combined fracture of the lateral malleolus and cuboid due to a lateral subtalar dislocation is an uncommon injury. Literature is scarce on this trauma association. To the best of our knowledge, this represents a new lesion pattern. Hereby we describe its mechanism, management and outcomes. CASE PRESENTATION: We report a case of a 58-year-old woman, who fell from the stairs and presented with pain and an acute deformity of the left foot and ankle...

BACKGROUND: Os peroneum and os vesalianum are sesamoid bones that could be found within fibularis longus and brevis tendons, respectively. They are rarely a cause of lateral foot pain and are often identified as incidental radiographic findings. However, in the context of trauma, these sesamoids may be radiographicallymisinterpreted as fractures. This study aimed to evaluate the prevalence and normal morphological variants of os peroneum and os vesalianum. MATERIALS AND METHODS: Standard oblique lateral and/or anteroposterior radiographic views of 624 feet of adolescent and adult patients were retrospectively reviewed to determine the prevalence and anatomical variations of the os peroneum and os vesalianum...

The purpose of this article is to focus attention on the abnormalities which the radiologist may encounter in patients presenting with lateral ankle or foot pain outside of the context of acute trauma. These include anterolateral impingement, subfibular impingement, subtalar instability and tarsal sinus syndrome, tarsal coalition, sural neuromas, peroneal tendon abnormalities, calcaneocuboid instability and occult cuboid fractures, and painful accessory ossicles. The expected and unexpected findings on radiographs, CT, US, and MRI are discussed...

OBJECTIVE: To highlight causal relationship between stress fracture in the presence of tarsal coalition and hindfoot pain in adolescents on magnetic resonance imaging (MRI). MATERIAL AND METHODS: A retrospective review was performed of the clinical and MRI imaging findings of 6 adolescents referred for MRI to evaluate symptoms of hindfoot pain with possible tarsal coalition. MRI studies were systematically assessed for cause of hindfoot pain, types of tarsal coalition, patterns of stress fractures, bone marrow oedema and any other associated features...

BACKGROUD: Modified tension band wiring is one of the most preferred surgical methods for transverse patellar fractures. However, the optimal depth or sagittal position of a Kirschner wire (K-wire) in modified tension band wiring has yet to be determined. The purpose of this study was to evaluate whether the depth of a K-wire affects the biomechanical characteristics of modified tension band wiring using the finite-element method. METHODS: A patella model was designed with a cuboid shape (length, 34...

INTRODUCTION: Talonavicular dislocation is a rare injury that usually occurs following high-energy trauma. The mechanism of injury is a force of abduction or adduction applied to the forefoot. In this article, we present a rare case of medial talonavicular dislocation with a fracture of the navicular following low-energy trauma. PRESENTATION OF CASE: We report a case of talonavicular dislocation with a navicular fracture in a 25-year-old male. He presented at the emergency department with a history of twisting injury to his left foot...

CASE: Cuboid impaction fractures (nutcracker fractures) result from high-energy trauma and are exceedingly rare in children. We present a case of an 8-year-old boy who sustained a comminuted cuboid nutcracker fracture after a fall from height. The patient underwent open reduction and internal fixation with a locking plate. At 1 year postoperatively, lateral column length and articular congruency were maintained, and the patient return to full function and activity. CONCLUSION: Cuboid nutcracker fractures in children are rare and can be successfully treated with open reduction and internal fixation with locking plates, with excellent radiographic and functional outcomes...
