Although the locking compression plate (LCP) system offers a number of advantages in fracture management, its successful use requires careful preoperative planning, consideration of soft tissue dissection principles, and good surgical technique. Failure to address these issues can lead to potential pitfalls. Therefore, there are many reports about potential(More)
Porokeratosis is a rare keratinization disorder of the skin characterized by annular plaques with an atrophic center surrounded by a raised keratotic wall that spreads centrifugally. We report a case of porokeratosis of Mibelli with mutilation. A 30-year-old woman presented with atrophic plaques on the index fingers of both hands with a keratotic ridge in(More)
BACKGROUND Heterotopic ossification is a common complication of surgery or trauma. OBJECTIVE To investigate the efficacy of levothyroxin in inhibition of heterotopic ossification. METHODS Heterotopic ossification was induced in 36 rabbits in three identical groups by injecting 2 mL of bone marrow in right thigh. To prevent heterotopic ossification,(More)
Transfer of proximal epiphysis and diaphysis of fibula is a treatment of bony defects in children. Although there are few reports of this procedure, different arteries or combination of arteries have been used as supplying pedicle and the reported success rates are different. This is an anatomical study to clarify the vascular anatomy of this region. A(More)
Radial shortening osteotomy is a well-accepted treatment for Kienbock disease in stages I to IIIA. The usefulness of this procedure in more advanced stages of the disease is controversial. In this study, 27 cases of stage IIIB and IV of Kienbock disease underwent radial shortening osteotomy and were followed for a mean period of 54.9 months (9 to 117 mo).(More)
INTRODUCTION Traditional treatment of unstable fifth carpometacarpal joint injuries is closed reduction and pinning. The purpose of this study was to determine the safest corridor for pinning of the fifth carpometacarpal joint to prevent iatrogenic injury to the ulnar nerve and tendons. MATERIALS AND METHODS In the first phase of study, three fresh(More)
Simultaneous volar dislocation of distal interphalangeal (DIP) joint and volar fracture-subluxation of proximal interphalangeal (PIP) joint of the same finger has not been reported yet. A 19-year-old man was referred due to pain on the deformed left little finger after a ball injury. Radiographs showed volar dislocation of the DIP joint and dorsal lip(More)
External fixation of comminuted hand fractures, especially those associated with soft-tissue injuries, is a good option and avoids several complications resulting from open surgery. Therefore, many versions of mini external fixators have been developed, including commercially fabricated implants and hand-made implants. However, these devices are costly or(More)
BACKGROUND Proper suturing technique is needed to ensure good outcome in extensor tendon surgery. Different techniques have been reported for the repair of extensor tendon injuries at the level of the metacarpophalangeal joint (MCPJ). These reports were in vitro studies on cadaver models. Repair techniques must be clinically tested, to determine results. (More)
Aneurysmal bone cysts (ABCs) are benign, nonneoplastic, expansile, vascular, locally destructive lesions. They represent 1% of all primary benign bone tumors; 3% arise from the sacrum, and 8–12% occur in the pelvis. The definitive etiology of aneurysmal bone cysts is still controversial. ABCs can exist either as primary bone lesions (70% of cases) or as(More)
