Closed extensor tendon rupture caused by Kienböck disease: a case report

Kienböck disease, a rare disease that can cause chronic pain and motor dysfunction, occurs due to avascular necrosis of the lunate bone, which leads to dislocation of the carpal bone. Among various other etiologies, Kienböck disease can cause closed tendon rupture of the finger. In this report, we introduce a case of total rupture of the second extensor digitorum communis and the extensor indicis proprius tendons caused by undiagnosed Kienböck disease in an elderly female patient.

Iatrogenic Spark Burn Injury to the Chest From a Transcutaneous Pacing Patch

Iatrogenic electrical burns that occur from the use of a defibrillator, a paddle-type cardiac shock device, have been reported in various forms. Electrical burns are usually conducted directly through the skin and are more damaging than scald burns or contact burns. A transcutaneous cardiac pacing device is a patch-type cardiac shock device that automatically delivers a shock when an abnormal heart rhythm is detected. We introduce a unique case of iatrogenic electrical burns caused by the transcutaneous pacing patch of a cardiac shock device. Electrical energy was converted into a spark due to foreign bodies deposited around the patch, resulting in damage to the peripheral area of the skin.

A propeller superficial transverse cervical artery perforator flap for defect coverage of the submental area: a case report

Reconstruction of submental defects is a challenge that needs to be approached carefully, since many important anatomical structures are located in this small space. Both aesthetic and functional outcomes should be considered during reconstruction. In this report, we describe a case where a superficial branch of the transverse cervical artery (STCA) perforator propeller flap was applied for coverage of the submental area. An 85-year-old woman presented with a 3-cm ovoid mass on her submental area. We covered the large submental defect with a STCA rotational flap in a 180° propeller pattern. The flap survived well without any complications at 1 year of follow-up. A STCA propeller flap is a useful surgical option in reconstruction for defect coverage of the submental area.

A giant solitary vellus hair cyst on the nasal root

Eruptive vellus hair cyst is a rare lesion of the vellus hair follicles as a result of developmental abnormality. This cyst is usually found in children, adolescents, and young adults most commonly involving the chest, upper and lower extremities, and abdomen. Herein, we introduce a 22-year-old male patient with a mass of nasal root, growing since childhood. The mass has grown over the years, causing the protruding of the nasal root contours, leading to decline in the patient’s aesthetic and mental quality of life. In response, we performed complete resection of the mass, which pathologically was a vellus hair cyst. The patient is now satisfied with his appearance and there was no local recurrence during follow up.

Traumatic Bowing of the Ulna with the Dislocation of the Radial Head: Report of a Case / 대한정형외과학회잡지

Although traumatic bowing of one or both bones of the forearm in children following acute trauma was reported by some authors, traumatic bowing of the ulna with dislocation of the radial head was described by only a few reports. We experienced one case of traumatic bowing of ulna associated with dislocation of the radial head and it was managed with open reduction of the dislocation of radial head and closed management of the bowing of the ulna. The result 1 year 10 months after treatment was very good, so we report this a case with related literatures.
