  • As more veterinary clinics become specialized with the growth of the companion animal market, an increasing number of veterinary clinics perform orthopedic surgery and use orthopedic products, some of which are defective and have side effects. Thus, the present study aimed to prepare fundamental data for the revision and development of manufacturing standards for these products in order to prevent their side effects. We conducted a survey targeting veterinary clinics as consumers and medical device companies as suppliers. Veterinary clinics were surveyed via offline and online methods; 320 clinics that offered orthopedic surgery and approximately 4,000 veterinary clinics that were registered in the Korean Veterinary Medical Association were targeted, and 153 veterinary clinics responded to the survey. The survey for medical device companies, was performed online, targeting 29 companies; 14 companies responded. The number of side effects of orthopedic products was higher in animal orthopedic products than in those for human use. Many consumers tended to suspect that side effects were caused by product defects. To resolve side effects after using orthopedic products, consumers mostly underwent reoperation. Meanwhile, some severe cases proceeded to legal disputes. Similarly, medical device companies, or the suppliers, responded that most side effects occurred in veterinary orthopedic products and that product defects and mistakes in use were the causes. As for most of the follow-up actions for side effects, these companies either reported the issue to those in charge or analyzed and resolved the issues themselves. Therefore, to develop quality products, suppliers should be provided with clear standards for the production, and information disclosure and a report system for side effects should be particularly established to gain consumers' trust regarding the safety of these products.

  • Purpose: To assess current practice in the treatment of osteoporosis in patients who underwent treatment for hip fracture in South Korea. Materials and Methods: A survey of 97 members of the Korean Hip Society, orthopedic hip surgeons who administer treatment for hip fractures in South Korea, was conducted. The survey was conducted for assessment of demographic data and perceptions regarding the management of osteoporosis in patients who have undergone treatment for hip fracture. Analysis of the data was performed using descriptive statistical methods. Results: The majority of participants were between the age of 41 and 50 years, and 74% were practicing in tertiary hospitals. Testing for serum vitamin D levels (82%) was the most commonly performed laboratory test. Calcium and vitamin D were prescribed for more than 80% of patients by 47% and 52% of participants, respectively. Denosumab was the most commonly used first-line treatment option for osteoporosis in hip fracture patients. Bisphosphonate was most often perceived as the cause of atypical femoral fractures, and the most appropriate time for reoperation was postoperative 12 months. Teriparatide was most preferred after cessation of bisphosphonate and only prescribing calcium and vitamin D was most common in high-risk patients for prevention of atypical femoral fracture. Conclusion: The results of this study that surveyed orthopedic hip surgeons showed that most participants followed the current strategy for management of osteoporosis. Because the end result of osteoporosis is a bone fracture, active involvement of orthopedic surgeons is important in treating this condition.

  • Purpose: To report the clinical results from using absorbable suture materials instead of nonabsorbable materials which have been used more commonly to repair Achilles tendon. Materials and Methods: We retrospectively reviewed 21 cases of acute Achilles tendon rupture, treated surgically from 2004 to 2011. Mean follow-up period is 6 months. We repaired Achilles tendon using size 1 Vicryl (Polyglactin 910, Ethicon) for core suture and size 3-0 Vicryl for epitendinous suture. At three months after surgery, we evaluated clinical results with single heel raise height by centimeters, differences of calf circumference and passive range of motion of ankle joint, compared to contralateral side. Also we recorded clinical results with subjective satisfaction grades. Results: At three months after surgery, 20 of 21 patients were able to perform single heel raise over 5 cm in height. Calf circumference differences were less than 1 cm in 12 cases, between 1 cm to 3 cm in 5 cases, more than 3 cm in 4 cases. There was no difference in range of passive motion in 19 cases. All patients satisfied with daily activity except 2 cases with mild discomfort. There was no complication such as rerupture, elongation or infection. Conclusion: We experienced excellent clinical results from repairing Achilles tendon with using absorbable suture materials in terms of functional outcomes and patient's satisfaction without any complication. So we may consider using absorbable suture materials instead of nonabsorbable materials to repair Achilles tendon.

  • Purpose: The first web space of the foot has a similar thickness and skin texture of the pulp of the fingers. Moreover, it has a reliable blood vessel and sensory nerve. The purpose of this study was to evaluate the clinical results of the first web space free flap to reconstruct the pulp of fingers. Materials and Methods: Authors have performed 23 cases of first web space free flap to reconstruct the pulp defect of the fingers between June 2004 and May 2009. The age of the patients ranged from 20 years old to 55 years old. The size of the flap ranged from $1{\times}1.5cm$ to $8.5{\times}2.5cm$. The mean flap area was 5.4 cm2. In 4 cases, we elevated the flap including lateral aspect of the big toe and medial aspect of the second toe. And then we made an artificial syndactyly to reconstruct the pulps on two fingers at the same time. In all cases, we performed 1 digital artery and 1 dorsal vein anastomosis. Every donor site that had a small defect healed spontaneously without any additional operations to cover it. Results: Of this type of surgery 21 flaps (91.3%) survived, 2 flaps (8.7%) failed. There was no severe complication in the donor sites. There was no walking disturbance due to the skin defect of the donor site. The static 2 point discrimination in 11 cases that we could check ranged from 3 mm to 15 mm. Conclusion: The authors believe that the first web space free flap of the foot is a good option for the reconstruction of the pulp of the fingers and it has a minimal donor site morbidity.

  • Purpose: To evaluate the efficacy of the arthroscopic exploration combined with modified Brostrom operation (MBO) for the treatment of chronic lateral ankle instability (CAI). Materials and Methods: Sixty patients who diagnosed a CAI were performed MBO. We divided to 2 groups, whether simultaneously inspected by arthroscopy (group B) or not (group A). The both group's results were compared according to American Orthopedic Foot and Ankle Society Ankle-hindfoot score (AOFAS), functional ankle score and visual analog scale (VAS) at preoperative and final follow-up period. Results: There were no significant differences of AOFAS, functional ankle score and VAS between both groups at final follow-up. However, in group A, 2 cases associated with medial ankle instability and syndesmotic injuries were did not diagnosed preoperatively, showed poor prognosis. In group B, one case had a permanent peroneal nerve symptom. The match rate of intra-articular lesions between preoperative diagnosis and postoperative arthroscopic diagnosis was 30% in group B. Conclusion: Combination of arthroscopic exploration and MBO is effective strategy for intra-operatively discrimination of intra-articular associated lesions for CAI.

  • Purpose: To compare the result of endoscopic versus open bursectomy in lateral malleolar bursitis, which was not treated conservatively. Materials and Methods: Between January 2008 and October 2009, We divided to two groups, endoscopy (group A) 11 cases, open bursectomy (group B) 11 cases. The average follow up period was 15 months (range, 12 to 18), the mean age was 66 (range, 38 to 79). We compared patients satisfaction, complete healing time, operation time, complications and recurrence. Results: Group A had significant difference in terms of the clinical satisfactions, complete healing time. operation time, complications. Group A showed satisfaction (excellent 9, good 2), mean complete healing time 11.9 (8~14) days, operation time 37 (25~45) minutes, 1 case recur. Group B showed satisfaction (excellent 4, good 3, fair 1, poor 3), complete healing time 32.7 (14~98) days, operation time 22 (18~26) minutes. complication were one case of skin necrosis, one case of wound dehiscence, two cases of superficial peroneal nerve injury, no recurrence. Significant advantages of endoscopic method include lower morbidity and rapid wound healing period (p<0.05). Conclusion: Endoscopic resection of the lateral malleolar bursitis is a promising technique and shows favourable results compared to the open resection. Significant advantages of this method include lower morbidiy and rapid wound healing.
