One of the most important factors leading to a successful healing of rotator cuff tear is good bone quality to secure the suture anchor in the bone for a stable fixation. However, rotator cuff tear are commonly found in elderly patients, and their proximal humerus often shows osteoporosis or cystic lesions. Especially when the transosseous repair prevails for a torn rotator cuff, a weak metaphyseal cancellous bone is often the case, which associated with difficulty in stable fixation of the lateral row suture anchor. In this situation, we were able to augment the lateral row fixation with polymethylmethacrylate bone cement. Although there is a concern of disturbance in the blood flow and healing potential, our case showed good clinical results with respect to healing. If we suspect a weak fixation of the lateral row suture anchor, bone cement seems to be a good option for augmentation.

A novel bioabsorbable suture material, poly(glycolide-caprolactone) (PGLCL) monofilament, was prepared by spinning of the PGLCL copolymer. The physical properties, strength retention, biocompatibility, and organism resolvability of the PGLCL monofilament were investigated. The results showed that the knot pull strength of the monofilament was higher than that stated in European Pharmacopoeia. The in vivo retention strength following implantation was 64%, 23%, 7%, and 0% after one, two, three, and four weeks, respectively. Mortality, clinical signs, validation, and sterility tests indicated that all items had passed. Organism resolvability tests showed that the PGLCL monofilament, as a suture, was absorbed within 91 days.

The purpose of this study was to observe the tissue response in applying staples and various suture materials to both scalp and buccal mucosa in rabbits. 18 rabbits were divided into 6 groups. The incised wounds of both scalp and buccal mucosa were sutured with staples, polyglactin 910, chromic catgut, mer silk and nylon. The experimental animals were sacrificed after 1, 3, 5, 7, 10, 14 days posto peratively 3 animals at one time. The tissue was stained with Hematoxylin and eosin, and Masson's Trichrom. In light microscopic examinations, the sutured sites were examined histologi cally according to 6 degrees about inflammation and collagen deposit. The results were obtained as follows, 1. The chromic catgut, an absorbable suture material, was absorbed by 7 days, whereas polyglactin 910 and mersilk began to get absorbed after 7 days. 2. Mersilk manifested a broad range of inflammation in the scalp, and both staple and nylon showed a severe inflammatory reaction in the buccal mucosa. 3. With polyglactin 910, both tissue samples showed only minor foreign body reaction, however in the scalp, the process of fibrosis took place compara tively slowly, whereas in the buccal mucosa, it occurred promptly and manifested active fibrosis by 7 days. 4. Mersilk showed widespread a matrix formation in both scalp and buccal mucosa, and showed the most severe inflammatory reaction by 3 days, which did not seem to decrease even after 7 days. 5. Both staple and nylon showed relatively a severe inflammatory reaction, however fibrosis took place rather promptly compared to the other groups. 6. Generally, in the buccal mucosa fibrosis occurred more promptly than in the scalp in both control and experimental groups. 7. Retention of the suture material and stability of the knot were the best with the staple, and better stability was manifested by the multi-stranded poly glactin 910 and mersilk than singlestranded chromic catgut and nylon. From above results, in the buccal mucosa absorbable suture materials especially polyglactin 910 showed better response in the aspect of inflammatory reaction, while in the scalp monofilament suture materials such as staple and nylon manifested a early fibrosis and collagen formation.

Ideal rotator cuff repair is to maintain high fixation strength and minimize gap formation for optimizing the environment of biologic healing of tendon to bone. Among the current repair techniques, the suture bridge technique is superior to single- or double-row repair in ultimate load to failure, gap formation, restoring anatomical footprint and achieving pressurized contact area. The suture bridge technique also minimizes gap formation and has rotational and torsional resistances allowing early rehabilitation. However, despite superior biomechanical characteristics of the suture bridge technique, there is no evidence that these mechanical advantages result in better clinical outcomes. Furthermore, there is no difference in failure rates between the double-row repair and suture bridge techniques. An appropriate repair technique should be determined based on tear size and pattern and tendon quality.

Purpose: The purpose of this study was to document the results of fixation with ethibond suture in akin osteotomy and its advantages. Materials and Methods: From May 2001 to January 2004, Akin osteotomy was performed in 218 patients. We reviewed 110 patients (114 feet) who were possible radiographic evaluation more than 6 months after operation. 110 feet had hallux valgus and 4 feet had hallux valgus interphalangeus. 105 patients were female and 5 were male. The average age was 43.8 years old (18 to 68 years old). The average follow up was 9 months (6 to 23 months). After performing the Akin osteotomy at 7 mm from the proximal articular surface of the proximal phalanx, one hole is made on either side of the osteotomy site with a K-wire. The passer was passed through the both holes and the ethibond was passed. And then, the ethibond was tied tightly. 2 sutures in 66 feet and 1 suture in 48 feet were made. Radiographic bone union at 6 months follow up was regarded as success and loss of the reduction, nonunion was regarded as failed. Results: In the radiographic evaluation, bony union were made at 6 months follow up in all feet. There was no difference between 2 sutures and 1 suture, and the knots were removed in 3 feet because of skin irritation. Conclusion: The fixation of the osteotomy site using suture material was an effective method in Akin osteotomy. The advantage of this procedure was unnecessity of the material removal.
