2024年12月22日 · Lunate/perilunate dislocations are high energy injuries to the wrist associated with neurological injury and poor functional outcomes. Diagnosis requires careful evaluation of plain radiographs. Treatment requires urgent closed versus open reduction and stabilization.

2020年10月28日 · Lunate dislocation is associated with following signs and symptoms: Significant pain in the wrist and palm of hand is a major symptom of lunate dislocation. Swollen wrist is another symptom of lunate dislocation. Difficulty in moving wrist and hand. Tingling feeling or numbness in fingers is also seen in lunate dislocation.

Perilunate and lunate dislocations result when great force is applied to a hyperextended wrist. They usually result from a fall on an outstretched hand or occur in a motor vehicle crash. Perilunate dislocations are more common than lunate dislocations. These dislocations cause pain, swelling, and deformity in the wrist and proximal hand.

2023年4月4日 · What are the signs of a lunate dislocation? People with lunate dislocations normally deliver after a high-impact fall onto an extended wrist. Generally reported signs to have pain in the wrist, swelling, reduced sensation, or paresthesia in the median nerve distribution secondary to carpal tunnel damage.

2023年1月10日 · Lunate dislocations are an uncommon traumatic wrist injury that require prompt management and surgical repair. The lunate is displaced and rotated volarly. The rest of the carpal bones are in a normal anatomic position in relation to the radius.

2020年9月3日 · The lateral radiograph is useful for detecting palmar dislocation and rotation of the lunate. Figures 1B and 2B show volar dislocation of the lunate from the lunate fossa, volar angulation of the lunate, loss of articulation and alignment with the radius and capitate, an abnormal scapho-lunate angle, and a “spilled teacup” appearance (1,2,5).

2023年10月6日 · Perilunate injuries are severe disruptions of carpal anatomy defined by dislocation of the capitate head from the concavity of the distal lunate. The spectrum of injury ranges from a perilunate dislocation (PLD), a soft tissue circumferential disruption around the lunate, to the transscaphoid perilunate dislocation (TSPLD), which involves a ...

Common symptoms of a volar lunate dislocation include: Painful swelling; Wrist deformity; Inability to extend digits due to pain; Causes of Volar Lunate Dislocation. Lunate dislocations typically occur in patients who have experienced trauma to a dorsiflexed wrist. Carpal dislocations make for less than 10% of all wrist injuries, with lunate ...

2023年8月14日 · Outline the common presenting symptoms and radiographic findings of perilunate dislocations. Summarize the complications and long-term sequelae of perilunate dislocations. Identify the importance of recognition and collaboration amongst the interprofessional team to improve outcomes for patients presenting with perilunate dislocations.

Doctors suspect perilunate and lunate dislocations based on symptoms and the circumstances of the injury. X-rays are taken to confirm the diagnosis. In people with a wrist dislocation, doctors manipulate the wrist bones back in place, without making an incision (called closed reduction). Then a splint is applied to immobilize the wrist and elbow.
