Delayed Rupture of Flexor Pollicis Longus after Volar Plating for a Distal Radius Fracture

Although extensor tendon rupture often occurs after volar plating for a distal radius fracture, a flexor tendon rupture is extremely rare. Most reported instances of flexor tendon ruptures after volar plating have involved improper placement of the plate, increased prominence of the distal edge of the plate because of collapse of the fracture site, use of custom-made plates, current steroid use by the patient, or a history of tendon injury. We report a case of delayed rupture of the flexor pollicis longus tendon 40 months after volar plating with a 3.5-mm T-locking compression plate for which the distal edge was located at the transverse ridge level of the distal radius. If symptoms such as tendon irritation occur in this situation, surgeons should consider removing the plate as soon as possible after bony union is achieved.

Delayed Rupture of Traumatic Intracranial Aneurysm Developed by Minor Head Trauma / 대한법의학회지

Traumatic subarachnoid hemorrhage (tSAH) can be almost immediately fatal. However, sudden death due to tSAH caused by delayed aneurysmal rupture is very rare sequela of mild head trauma. We experienced a death case of a 47-year-old woman who had subarachnoid hemorrhage and intraventricular hemorrhage 3 days after head trauma. Delayed death after any kinds of trauma is important to forensic and legal aspects. Herein we report a case of fatal subarachnoid hemorrhage caused by delayed rupture of traumatic aneurysm.

Delayed Rupture of Flexor Pollicis Longus by Plate for Fracture of the Distal Radius

PURPOSE: Delayed rupture of flexor pollicis longus as a sequelae of the plate inserted for distal radius fracture is a very rare. This is the first case reported and published in Korea. METHODS: A 48 years old female patient visited hospital, complaining flexor disturbance of interphalangeal joint of left thumb, which suddenly occurred without any external wound. We found that she had received operation of fixing plate for fracture of left distal radius 10 years ago. As operational opinion, we have checked that flexor pollicis longus tendon has been ruptured with oblique ways being stimulated by extended plate to palmar side over long period. RESULTS: Authors performed tenorrhaphy of flexor pollicis longus without tendon graft and presented a successful active flexion of the left thumb interphalangeal joint 1 year after the operation. CONCLUSION: If the extruded part of the end plate is observed during the operation or follow-up, it is considered to be necessary to get rid of the plate as early as possible after the fracture healing.

Delayed Rupture of the Transverse Atlantal Ligament Complicated after the Treatment of Posterior Neck Abscess: A case report / 대한척추외과학회지

Atlantoaxial instability with rupture of transverse atlantal ligament is mostly caused by trauma, and this can be combined with myelopathy. Although it gives rise to no neurologic deficit, it has a high possibility to quadriplegia or death by minor trauma. We experienced a rare case about atlantoaxial instability with delayed rupture of transverse atlantal ligament that was complicated after the treatment of posterior neck abscess. A 44-year-old male patient had complained of posterior neck pain for 1 month. Based on a clinical examination, simple radiography, CT and MRI, his diagnosis was posterior neck abscess. He underwent an emergency operation with open drainage. One year later, he again had posterior neck pain. Atlantoaxial instability with rupture of the transverse atlantal ligament was confirmed. Skeletal traction was applied and then C1-2 posterior fusion without wiring was performed. After the operation, antibiotics were injected for 4 weeks and a halo-vest was put on for 6 months. Complete fusion of C1-2 was obtained without posterior neck pain at the 1 year follow-up.
