Purpose: In this study, we introduced a newly developed technique of operation for hallux valgus. We used a single dorsal incision to correct major components of Bunion in stead of two or three incisions, which had been used by most of surgeons for long time. Materials and Methods: Between 2003 and 2005, 27 feet with hallux valgus deformity were operated through single dorsal incision. 10 out of 17 patients underwent operation on both feet, 5 patient underwent operation on left feet, remaining 2 underwent operation on right. There were 16 women and 1 man. Average age of patients was 45 (range, 21-59). Post operatively all feet were evaluated by physical examination, Maryland Foot score profile, radiographic measurements and complication. Results: Maryland foot score profile increased from preoperative 67/100 to postoperative 95/100. Most patients satisfied pain relieve and cosmesis. Average preoperative intermetatarsal angle was 15 degrees, which were decreased to 9 degrees after operation and average preoperative hallux valgus angle was 32 degrees, which were decreased to 12 degrees after operation. Conclusion: According to our experience, the single dorsal incision technic for correction of moderate to severe hallux valgus deformities was rather safe and easily performed without noticeable complication with almost same results as multiple incisions technics. We highly recommend this technic to be tried by foot surgeons without hesitation.

The Author examined the clinical and histological changes on the dorsal tongue mucosa of the adult rats after lasing by pulsed Nd:YAG laser and incising with scalpel. The dorsal tongue was lased through 320$\mu\textrm{m}$optic fiber moving 2.5mm/second to make linear incision 5mm. The five conditions of lasing were three application with 1.0W, 1.75W, 3.0W and 3.0W under saline cooling, and single application with 3.0W at 20Hz. With scalpel, linear incisions through the surface epithelium were performed to 5mm in length. After observing the clinical changes of the incised wounds, the animals were sacrified and the tissues were excised to make the tissue specimens. The stained microscopic tissue slide were observed histologically under the microscope. The following results were obtained : 1. While incision with scalpel causes severe bleeding, lasing does not cause bleeding. 2. In three applications with 1.75W and 20Hz, tissue ablation was limited to areas contacted with optic fiber. 3. In three applications with 3.0W and 20Hz, deep incised wound, extensive destruction of the adjacent epithelium and charring were observed. 4. In three applications with 3.0W and 20Hz under saline cooling, tissue ablation was limite to the superficial mucosa and charring was not observed. 5. In single application with 3.0W and 20Hz, the shape of the incised wound was similar to that of the scalpel incision.

Acute compartment syndrome of the lower leg and foot is a surgical emergency. The clinical symptoms is an important clue to diagnose compartment syndrome. In cases of ambiguous diagnosis, unconscious patients and children additionally need a intracompartmental pressure measuring. Immediate fasciotomy should be performed when clinical signs are obvious or when delta pressure is less than 30 mmHg or intracompartmental pressure is greater than 30 mmHg. Fasciotomy of the lower leg can be performed either by one lateral single incision or double incision, which of the foot mainly has a dorsal or medial incision. A delayed in diagnosis that leads to a delay in treatment can result in devastating disability. Acute compartment syndrome of the lower leg and foot is a relative rare but serious complication of which a surgeon should be aware.
