ABSTRACT
PURPOSE: The purpose of this study was to analyze the clinical results of application of bioabsorbable screws in hallux valgus surgery using modified Mau osteotomy. MATERIALS AND METHODS: We retrospectively reviewed medical records of 25 patients. Operations were performed between May 2013 and January 2014. We performed 33 modified Mau osteotomies and fixed using bioabsorbable screws. Mean age of patients was 52 years (range 19 to 71). Mean follow up duration was 13.2 months (range 12.3 to 18.9). The clinical evaluations included pain visual analogue scale (VAS) score, American Orthopaedic Foot and Ankle Society (AOFAS) score, and satisfaction score. Weight bearing anteroposterior radiographs were taken for measurement of hallux valgus angle (HVA), intermetatarsal angle (IMA), and distal metatarsal articular angle (DMAA). All radiographs were evaluated in order to detect complications related to bioabsorbable screws such as osteolysis, cyst formation, and fixation failure. RESULTS: The mean pre- and postoperative pain VAS scores were 4.0 and 1.7 (p<0.05). The mean AOFAS score improved from 52.6 to 82.8 (p<0.05). Preoperative HVA and IMA were 31.2 and 13.9, respectively. Postoperative HVA and IMA were 5.2 and 6.2 (p<0.05). The DMAA increased from 7.8 to 9.9 (p<0.05). There was one case of superficial wound infection and one loss of correction, and no case of osteolysis, cystic formation around the screw, or deep infection. All patients showed union without fixation failure. CONCLUSION: The clinical and radiological evaluation of this study demonstrates reliable results without fixation failure or allergic reaction. The use of bioabsorbable screw appears not to be inferior to metal screw fixation in hallux valgus surgery.

The Akin osteotomy is a complimentary procedure in hallux valgus surgery. Surgical techniques may vary depending on the operators or fixation devices. Suture fixation, for which a removal procedure is not necessary, can often be recommended. However, there is a risk of failure due to the thin cortex of the phalanx. We describe a new technique using Ethibond suture fixation in Akin osteotomy, which can lower the risk of phalangeal cortical failure and articular cartilage irritation. First, the Akin osteotomy was performed on the proximal phalanx 5 to 6 mm distal to the first metatarsophalangeal joint. Then bone holes were drilled from dorsum to plantar parallel to osteotomy with the Kirschner wire. The final procedure involved passing the Ethibond sutures connected to a straight needle through the holes and tying it. This fixation method offers an effective and easy technique for performance of Akin osteotomy.

BACKGROUND: This study was undertaken to investigate the trends in domestic publications on bone metabolism during the last decade, and to document the characteristics of articles in South Korea. METHODS: Articles on bone metabolism including osteoporosis published between 1998 and 2012 were evaluated, in terms of title, type of articles, subspecialty, and authors' affiliations. We used descriptive statistics for presenting the characteristics of domestic publication on bone metabolism. RESULTS: Total of 247 articles, published articles between 1998 and 2012, were reviewed. Over a total study period of 14 years, the number of articles which was initially 109 in the first half term increased to 247 during the period of second half. Of these 247 articles, 52 were on basic research, and 195 were on clinical research. Although the types of article were added in the later 7 years were much diverse than that of the earlier 7 years, the proportion of original articles has decreased. CONCLUSIONS: Our findings presented the characteristics and trends of domestic publication on bone metabolism in South Korea, and concerns for editorial boards in future.
