An isolated cuboid dislocation. A case report.

ABSTRACT: Isolated cuboid dislocations are rare injuries Jacobson (1990). It is clinically significant and important in surgical education, as it is an injury and a source of lateral foot pain that can be misdiagnosed at the time of initial presentation and may be difficult to identify clinically or with imaging Drummond and Hastings (1969).We present a case report in a 33year old rugby player, who was injured during a match after a tackle. The patient had ongoing concerns that he was not recovering following initial discharge, as he was unable to weight bear since his initial presentation to the Emergency Department (E.D.), and he had ongoing lateral foot pain.Important clinical findings include lateral foot pain, a palpable gap at the cuboid level and difficulty weight-bearing. Closed reduction is usually difficult as it can be blocked mechanically by the extensor digitorum brevis muscle or peroneus longus tendon Dobbs et al. (1969). Initial X-Rays may be inconclusive with this presentation. CT scanning is indicated if suspicion for pathology is high. Open reduction and internal fixation with Kirschner wires are usually necessary for isolated cuboid dislocations.Our take home message from this case report is that cuboid dislocations are rare injuries and are important to be aware of in reviewing X-rays in the E.D. Particularly in patients with inversion and plantar flexion type injuries to their foot and ankle joint, with an inability to weight bear and lateral midfoot pain following their injury.

Fracture neck of the talus with isolated talonavicular dislocation: A case report.

Project description:IntroductionTalar neck fractures are injuries which frequently result in adverse outcomes or impairment of functional activity. Four groups were identified according to Hawkins classification and Canale modification. We present a female patient with a fractured neck of the talus associated with talonavicular dislocation, but intact tibiotalar and subtalar joints; an injury pattern not fulfilling the criteria described in the Hawkins classification.Patient concernsA 46-year-old woman missed a step and fell down stairs with an immediate painful right ankle and inability to bear weight.DiagnosisTalar neck fracture with an unusual isolated talonavicular dislocation.InterventionsTemporary closed reduction followed by open reduction and internal fixation were performed.OutcomesThe patient had excellent functional and radiological outcomes following surgical management.ConclusionWe discuss the management of this rare case in addition to a review of the current literature to provide the best evidence-based recommendations for this injury pattern.

Isolated complete dislocation of hamate bone with an ulnar nerve injury: a case report and literature review.

Project description:BackgroundIsolated complete dislocation of the hamate bone is a rare wrist injury. Only 22 cases have been reported in the literature. Four of them were associated with nerve injury, but it is a pity that the causes of ulnar nerve injury had never been deeply analyzed. In the case report, it was stated that the ulnar nerve injury was caused by both displacement of uncinate bone and change of position of transverse carpal ligament. The complete dislocation of the hamate bone is mostly caused by direct force, often accompanied by tears of the surrounding ligaments.Case descriptionA 30-year-old woman was treated because her left hand was crushed by a machine roller. Plain film X-ray showed isolated dislocation of the volar hamate and rotation of the hamate bone to the volar side. Clinical manifestations and computed tomography (CT) signs suggest ulnar nerve injury. The patient was quickly transported to the operating room for open reduction and internal fixation of the hamate bone and repair of the dorsal carpal ligament. The patient fully recovered after 12 months.ConclusionsIsolated complete dislocation of the hamate bone is a rare injury. The most common cause is direct compression force to the wrist. Diagnosis can be made through review of the patient's medical history, physical examination and X-ray, however, CT can accurately evaluate the displacement and rotation of the hamate bone, hamate bone fracture and other concomitant wrist fractures, suggesting compression changes of the median nerve and ulnar nerve to provide a reliable basis for the formulation of a clinical care plan. The case report added the evidence-based practice, and discussed the anatomical mechanism and imaging manifestation of ulnar nerve injury associated with complete dislocation of hamate bone.

An Isolated Pure Dislocation of Fifth Carpometacarpal Joint: Case Report and Review of Literature.

Project description:Isolated pure dislocation of the fifth carpometacarpal (CMC) joint is a very rare injury and classified depending on displacement of the metacarpal base. This rare injury is often difficult to recognize and is liable to be overlooked. The purpose of this case report is to present a patient with an isolated dislocation of the fifth CMC joint that was satisfactorily treated with closed reduction and ulnar gutter pop slab.A 21-year-old male presented with severe pain on the right carpus following a fall with injury to right hand. There was a mild swelling at fifth CMC joint region and a bony prominence was felt dorsally, little finger presented an abduction deformity, and there was apparent shortening of the fifth ray. A diagnosis of isolated dislocation of fifth CMC dislocation was made based on radiographs. Immediate closed reduction was done in emergency room by applying longitudinal traction and direct pressure on metacarpal base dorsally, reduction was stable and confirmed by postreduction radiographs.Isolated pure dislocation of the fifth CMC joint is very rare injury and is prone to be missed in emergency room and particular attention should be made to diagnose it in polytrauma patients.

Posterior dislocation of a constrained total knee arthroplasty: A case report.

Project description:IntroductionDislocation of the knee after primary total knee arthroplasty is rare in a posterior stabilized knee and extremely rare in a constrained total knee arthroplasty. Constrained total knee prostheses are used for severe knee deformities and to provide stable and mobile knees.Presentation of caseIn this case, we describe a dislocation of a primary constrained total knee arthroplasty using the Genesis II (Smith & Nephew, Memphis Tennessee, USA) prosthesis. Without any significant trauma, the constrained insert dislocated fifteen months after surgery and revision surgery with a bigger insert was needed. Surgical error may have been the cause of dislocation, but we were unable to establish a clear reason behind this dislocation.DiscussionKnee dislocation after TKA is rare but easily overlooked and can lead to serious complications and permanent disability. This system should provide stable and mobile knees to correct collateral ligament laxity.ConclusionHere, we report the first case, to our knowledge, of dislocation with a constrained prosthesis without any history of trauma.

Posterior shoulder dislocation in a 10-year-old child: Case report.

Project description:IntroductionShoulder dislocation is the most common type of all joints dislocations. It occurs when there is separation in the glenohumeral joint. Posterior dislocation accounts for less than 4% of all shoulder dislocations. In fact, it is misdiagnosed in 60-79% of the patients in the initial presentation. In children a posterior shoulder dislocation is usually caused by a congenital anomaly or in those who have ligamentous laxity. Traumatic posterior shoulder dislocation without fracture of the proximal humeral epiphysis in children is very rare, and only few cases have been reported.Case presentationThis report presents a rare case of a 10-year-old child with a traumatic posterior shoulder dislocation without fracture.Discussionthis patient present with a rare posterior dislocation, which is direct and without fracture. It does not present with a marked deformity and it is hard to detect without a complete physical examination and radiographic series.ConclusionPosterior shoulder dislocations are rare, and even more rare in children without fractures. It is easily missed and needs careful history taking, physical exam and correct x-ray view to reach the diagnosis.

Arytenoid cartilage dislocation mimicking bilateral vocal cord paralysis: A case report.

Project description:RationaleArytenoid dislocation is very rare and may be misdiagnosed as vocal cord paralysis or a self-limiting sore throat.Patient concernsA 70-year-old male (70 kg, 156 cm) was scheduled for transurethral resection of bladder tumors. A McGrath videolaryngoscope, with a basic cuffed Mallinckrodt oral tracheal tube of 7.5 mm internal diameter, was used to successfully intubate his trachea. The duration of surgery was 25 minutes. In the recovery room, he complained of sore throat and dyspnea with inspiratory stridor, which were not resolved after intravenous injection of 10 mg of dexamethasone.DiagnosesThe otolaryngological examination revealed midline fixation of the bilateral vocal folds, suggestive of bilateral arytenoid dislocation or bilateral vocal cord palsy. The latter was ruled out because there was no evidence of recurrent laryngeal nerve injury.InterventionsUnder general anesthesia, a closed reduction was performed using laryngoscopic forceps to apply posterolateral pressure on the arytenoid joints on both sides. Only the dislocation of the left cricoarytenoid joint could be easily reduced, whereas reduction of the right joint was not possible.OutcomesOn postoperative day 7, examination with a rigid laryngoscope showed a medially fixed right vocal fold, with full compensation by the left vocal fold. Computed tomography of the neck showed no pathologic findings. Six weeks after surgery, the patient had regained his normal voice with no complications.LessonsAlthough arytenoid dislocation is a rare complication, it should be considered even in patients with uncomplicated tracheal intubation. Early diagnosis and the optimal therapeutic approach are critical for restoration of the patient's original vocal cord function.

Percutaneous extraction of a leadless Micra pacemaker after dislocation: a case report.

Project description:BackgroundLeadless pacemaker implantation rates are increasing worldwide. Until now leadless pacemaker dislocation and extraction has been rarely reported.Case summaryAn 83-year-old patient with cardiac amyloidosis, chronic atrial fibrillation, and complete heart block was implanted with a leadless pacemaker (Micra, Medtronic). On the day after implantation, the device showed an exit block and on cardiac echocardiography and cardiac computer tomography, a device dislocation could be detected. During the day, the device moved at least three times between the tricuspid valve and the right ventricular apex. Each time causing non-sustained ventricular tachycardia. At the next day device extraction was scheduled. After 189?minutes of procedure time, it was possible to retrieve the device with the help of two steerable introducers (Agilis) and two snare catheters.DiscussionImplantable transcatheter leadless pacemakers can be implanted safely most of the time. However, in rare cases device dislocations may occur. Device extraction is possible, but is described as challenging in most published cases 10.1093/ehjcr/ytz113_audio1 ytz113_audio1 6074457264001.

Multiple chromoanasynthesis in a rare case of sporadic renal leiomyosarcoma: case report

Project description:Renal leiomyosarcomas (LMS) are extremely rare neoplasms with aggressive behaviour and poor survival prognosis. The most frequent somatic events in leiomyosarcomas are mutations in TP53, RB1, ATRX and PTEN genes, chromosomal instability and chromoanagenesis. By using chromosomal microarray analysis we identified monosomy of chromosomes 3 and 11, gain of Xp (ATRX) arm and three chromoanasynthesis regions (6q21-q27, 7p22.3-p12.1 and 12q13.11-q21.2), with MDM2 and CDK4 oncogenes copy number gains, whereas no CNVs or tumor specific SNVs in TP53, RB1 and PTEN genes were observed.
