Iatrogenic Subtrochanteric Fractures Related to the Surgical Error: Two Cases Report

Iatrogenic fracture is not popular and might be recognized as a malpractice. Surgical error related to iatrogenic fracture which has occurred after an operation can be detected only by a surgeon. Stress riser fracture is another form of iatrogenic fracture also known as a Young's modulus fracture. As the majority of surgical related stress riser fractures can be preventive, the accurate prevalence is not known. The majority of fractures occurred in the weight bearing bones such as femur and tibia. The subtrochanter area is the most stress concentrated area in the human body, thus it is a common area for occurrence of stress riser iatrogenic fractures. We experienced 2 cases of stress riser iatrogenic fractures, which are related to technical errors, thus we report cases with literature review.

Total Rupture of Peroneus Longus Tendon Through an Os Peroneum Fracture Treated by Tendon Transfer (A Case Report) / 대한족부족관절학회지

Fracture of os peroneum can occur, but the fracture fragments are seldom displaced. Complete rupture of peroneus longus through the fracture of the os peroneum causing displacement of the fracture fragments is not well reported in the literature. Differential diagnosis with bipartite os peroneum or calcific tendinitis is important because misdiagnosis of the tendon rupture can lead to serious sequela including chronic pain, ankle instability, and peroneal compartment syndrome. We report a case of complete rupture of peroneus longus associated with fracture of the os peroneum with a review of the literature.

Calcific Tendinitis of Peroneus Longus Tendon (A Case Report) / 대한족부족관절학회지

Calcific tendinitis usually occurs in the supraspinatus tendon of the shoulder. Calcific tendinitis of the peroneus longus tendon has not been reported on the Korean journals. Differential diagnosis includes bipartitis os peroneum, os peroneum fracture and peroneal tendinitis. We report a rare case of calcific tendinitis of the peroneus longus tendon which responded well with the conservative treatment.

Adjuvant therapy with Nd-YAG laser and triamcinolone injection in the treatment of urethral stricture / 대한비뇨기과학회지

Treatment of benign urethral strictures is difficult because of a high rate of recurrence. In general, electrocautery resection of fibrous scar tissues has been unsatisfactory. Since the irregular thermal injury may only promote further scarring. Because of their unique physical properties and tissue erect lasers theoretically offer advantages over conventional techniques for treatment of urethral strictures. The thermal injury resulting from neodymium:YAG laser irradiation may heal with more elastic properties and less fibrous contraction than an electocautery bum. According endoscopic application of laser energy could produce thermal coagulation of the fibrous area with a secondary slough or the scar tissue and reepithelization without scar. Contraction and epithelization are two phenomena of wound healing which are retarded by steroid Triamcinolone activates collagenase which enhanced degradation of scar tissue. A totaI 28 cases with benign urethral strictures underwent treatment with circumferential triamcinolone injection and application of neodymium:YAG laser irradiation to the scarred area after endoscopic cold urethrotomy. There were no adverse effects and although 6 patients suffered recurrent strictures within 2-17 months. the postoperative results were good in all patients including recurrent cases. We reviewed our experience with neodymium:YAG laser treatment of benign urethral strictures.
