We report a rare case of translunate, transradial, transtriquetral, transtrapezoid perilunate dislocation with multiple metacarpal neck fractures in a young adult. The injury was treated with open reduction and internal fixation. Although the injury was severe, the patient had a satisfactory functional result.

BACKGROUND: Perilunate dislocations and fracture-dislocations are a subcategory of the carpal instability complex. Herein, we report our university hospital experience with this complex injury. The goal of our study was to find predictive factors and quantify the development of arthritis and lunate necrosis. We tried to measure the impact of arthritis on hand function. METHODS: Between January 2000 and December 2014, 21 patients underwent surgery for perilunate dislocations and perilunate fracture-dislocations of the wrist in our tertiary university center...

Introduction: The anterior perilunate dislocations of the carp (PDC)are exceptional and poorly known lesions, which may go unnoticed in an emergency. They derive their importance from the severity of sequelae, which are dominated by chronic wrist instability and long-term osteoarthritis. Case Report: We report the case of an open anterior PDC with no carpal fracture in a young patient. The injury occurred in a road accident and was treated at once with satisfactory results 1year after...

OBJECTIVE: The aim of this study was to analyze the risk factors contributing to the misdiagnosis of perilunate injuries. METHODS: The study included patients who had perilunate dislocation or fracture dislocation correctly or incorrectly diagnosed on initial examination between 2008 and 2014. Data related to the length of time until correct diagnosis of the perilunate injury; cause of injury; presence of associated fractures, polytrauma or concomitant trauma in the ipsilateral upper extremity; time between injury and first presentation; first treatment applied; presence of ligamentous perilunar injuries only or fracture and dislocation; inadequate radiographic assessment; and experience of the physicians were recorded and analyzed...

PURPOSE: Perilunate injuries are rare, severe injuries of the carpus. They can present as isolated injuries or in the poly-traumatised patient. This is the first documented series of these injuries treated in a Major Trauma Centre. The aims were to assess the management, treatment algorithm and outcomes, of perilunate injuries in our department, review whether concomitant polytrauma affected those outcomes and identify if delay to definitive treatment had a significant effect on overall outcome...

REVIEW
Bo Liu, Shan-Lin Chen, Jin Zhu, Guang-Lei Tian
The key to successful treatment of perilunate injuries is to achieve early anatomic reduction and maintain the carpal alignment. Open surgery may lead to capsular scarring and joint stiffness. Furthermore, there is increased chance of damage of the already tenuous blood supply to scaphoid and the torn ligaments. Recently, arthroscopic-assisted management of perilunate injuries has been suggested. This article describes the surgical technique and outcome of this minimally invasive approach for perilunate injuries...

Axial fracture-dislocations are rare, high-energy injuries. Although cases of axial fracture-dislocations are reported in the literature, there are few reports of a patient who suffered a combined perilunate injury with an ulnar axial dislocation of the hand. This case report describes the anatomical injury and operative treatment of a patient who suffered this injury and discusses the importance of associated soft tissue management.

Acute lunate dislocations are unusual and devastating injuries to the wrist. They are very rare in adult wrist injuries but extremely rare in children. Only six cases of perilunate dislocations in children have been reported in the literature, and in addition to this, only a single case of a lunate dislocation in a child has been reported.Here, we report a case of a 10-year-old boy who presented with an acute lunate dislocation of the wrist, following trauma, a second of its kind.

Lunate and perilunate dislocations are uncommon, but they have clinical importance because complications, such as median neuropathy and avascular necrosis of the lunate, can occur. Although early diagnosis enabling early surgical treatment is crucial for preventing long-term sequelae, these dislocations are frequently missed in the initial assessment. Imaging tools, such as plain radiography, magnetic resonance imaging, ultrasonography, and electrodiagnostic studies, have been used for diagnosis. The proper choice of initial evaluation tools is important for making an accurate early diagnosis...

Perilunate dislocations are rare injuries comprising of less than 10% of all wrist injuries. These usually occur after high-energy trauma to the wrist. One-fourth (25%) of perilunate dislocations are missed at the initial presentation. We report a case of perilunate dislocation in a patient who presented late, about two months after trauma. He underwent open reduction through a single dorsal approach and internal fixation with K-wires. Aggressive physiotherapy exercises were started after removal of K-wires...

OBJECTIVE: To qualitatively assess surgeries performed in patients with perilunate dislocations without associated fractures, who were operated using the closed reduction and percutaneous fixation method. The follow-up time ranged from one to seven years. METHODS: 628 patient records with traumatic wrist injuries, operated by the same group of Hand Surgeons between 2008 and 2014 due to acute trauma were collected, with a mean follow-up of 3.2 years. Of these, 51 were cases of perilunate fracture-dislocations, and 38 were pure perilunate dislocations without associated fractures; of these, only 32 underwent percutaneous fixation without ligamentous repair, thus meeting the inclusion criteria...

Trans-scaphoid transcapitate (TSTC) perilunate fracture-dislocation (PLFD) is a rare type of perilunate injury. Because of the rarity and complexity of this entity, initial diagnosis may be delayed and the extent of osseous and ligamentous lesions underestimated. Early surgical treatment by open reduction and fracture stabilization is recommended to avoid complications such as avascular necrosis, nonunion, posttraumatic arthritis, and functional impairment. In this article, we report the case of a 32-year-old man who sustained a TSTC-PLFD...

The midcarpal joint can be classified into two anatomical types - Viegas type I and Viegas type II - based on the absence or presence of a medial facet for the hamate on the lunate (lunohamate facet). Type I is associated with a round capitate shape, which theoretically allows better congruence with the lunate fossa of the distal radius following proximal row carpectomy (PRC). This morphological feature has never been considered as a predictive factor of clinical outcome for this surgical procedure. This study aimed to compare the clinical and radiological outcomes of the two Viegas types following PRC...

Background: Perilunate fracture dislocations are often associated with fractures of the distal pole of the scaphoid or the proximal pole of the capitate. However, the combination of perilunate dislocation with multiple carpal fractures and associated scaphocapitate syndrome is very rare. Methods: We report a unique case of scaphocapitate fracture syndrome with perilunate dislocation and fracture of the hamate resulting from a high-energy injury to the wrist during a dirt-bike competition. Results: Open reduction and internal fixation of the scaphoid fracture with a 3...

PURPOSE OF THE REVIEW: Scapholunate and perilunate injuries can be difficult to diagnose and treat in the athlete. In this review article, we present the mechanism of injury, evaluation, management, and outcomes of treatment for these injuries. RECENT FINDINGS: Acute repair of dynamic scapholunate ligament injuries remains the gold standard, but judicious use of a wrist splint can be considered for the elite athlete who is in season. The treatment of static scapholunate ligament injury remains controversial...

INTRODUCTION: Perilunate dislocations are commonly seen after fall on an outstretched hand in extremes of dorsiflexion and ulnar deviation. A greater arc injury is one when there is an associated fracture of one or more bones around the lunate while a lesser arc injury is associated with pure ligamentous disruption around the lunate. CASE REPORT: We report a unique case of bilateral trans-scaphoid perilunate dislocation in a 35-year-old male labourer. This is the first reported case where the lunate dislocated into the forearm on the volar aspect...

PURPOSE: Some authors have proposed performing proximal row carpectomy (PRC) as the initial treatment for perilunate dislocations. HYPOTHESIS: The goal of this retrospective study was to compare the results of a cohort of perilunate dislocation cases that were operated by open reduction and internal fixation (ORIF) or by PRC between 2006 and 2011. METHODS: The cohort consisted of 21 men with a mean age of 33years, who either had an isolated perilunate dislocation (7 cases) or a fracture-dislocation (14 cases)...

Kienböck disease is a condition that typically occurs in the "at-risk" patient, in the "at-risk" aspect of the proximal condyle of the "at-risk" lunate. In the active male, repetitive loading causes the stress fracture that commences in the single layer proximal subchondral bone plate. The lunate fracture commences at the point the lunate cantilevers over the edge of the distal radius, and then takes on the shape of the radius. We postulate that the stress fracture violates the parallel veins of the venous subarticular plexus-leading to localized venous hypertension and subsequent ischemia and edema of the fatty marrow...

Perilunate fracture-dislocation is rare. We report the case of a 24-year-old male who fell from his motorcycle and presented with a transverse lunate fracture with perilunate ligament damage. The initial diagnosis based on X-rays was confirmed by CT scan. A dorsal approach was used to obtain good reduction, double screw fixation and ligament reinsertion protected by temporary K-wires. To the best of our knowledge, this is the first case of transverse lunate fracture within perilunate fracture-dislocation. The patient returned to normal activities after 6 months...
