Purpose: The purpose of this study is to evaluate the short-term clinical outcome of the capsulolabral repair using absorbable suture anchor in traumatic anterior instability of shoulder. Materials and Methods: From June 2000 to September 2001, 15 shoulders with recurrent anterior instability were operated with arthroscopic Bankart repair using absorbable suture-anchor 'PANALOK' (Mitek, westwood, MA), and were followed up over 1 year (average; 13 months). The mean age was 23-years. There were fourteen males and one female. The mean duration from the initial symptoms to the operation was 24 months. Associated pathologies were Hill-Sachs defect in 12 cases, SLAP in 6 cases, and partial rotator cuff tear in 2 cases. The results were evaluated by patien's satisfaction, Modified Rowe Score in regard to joint stability, mobility, pain and function in comparison with the preoperative ones, and other complications. Results: At the last follow-up, the total Rowe Score increased from 38 points to 92 points. There were no recurrence and 14 patients among 15 patients gained pre-operative level of sports activity and no other complications. Conclusion: Effective capsulolabral repair could be obtained by the absorbable anchoring without any untoward complications. This procedure is simple and safe one and this system can be a good substitute for the metallic anchor.

Purpose: This paper analyzes the results of arthroscopic bankart repair for anterior recurrent dislocation following a trauma on shoulder. Material and Methods: The subjects were twenty-three (23) cases that were available to follow up for more than eighteen months during the period from November 2001 to June 2003 and were chosen from patients to whom arthroscopic bankart repair was applied using a knotless suture anchor for their traumatic anterior recurrent dislocation on the shoulder. Their average age was 28 (ranging from 15 to 60) with 20 males and 3 females. The injury from sports activities accounted for the most cases with 14 subjects. The average follow-up period was 27 months (ranging from 18 months to 35 months). There were 19 cases of bankart lesions, 4 cases of ALPSA lesions and associated with 5 cases of partial tear in the rotator cuff. The anchors employed were knotless anchor (Mitek) for all the cases. Rowe scoring scale was adopted to judge the results after operations. Patients' subjective satisfaction and range of motion of external rotation were addressed together. Results: Rowe scores showed that 20 cases (87%) reaches the level of 'good' and hinger. The average patients' satisfaction accounted for 90 points out of 100. It was also found that external rotations averagely decreased by 6.5 degree when the range of motion was in at the side. Conclusion: There were satisfactory results of arthroscopic bankart repair using knotless suture anchors as an operative treatment for traumatic anterior recurrent dislocation on shoulder.

Purpose: Rotator cuff tears involving the subscapularis are less common than those involving the superior and posterior rotator cuff. The purpose of the present study was to report the clinical results of repair of isolated traumatic tears of the subscapularis tendon. Materials and Methods: Fifteen patients (13 males, 2 females; mean age 46.2 years; range 35 to 52) with unilateral ruptures of the subscapularis tendon after trauma who underwent arthroscopic repair between February 2003 and October 2008 were reviewed retrospectively. All the cases were isolated tears of the subscapularis without the involvement of any other rotator cuff tendon and were followed for at least two years (mean 28 months). The entire subscapularis was involved in 9 cases and the tear was localized to the upper two thirds in 6 cases. The preoperative and postoperative status of patients with isolated subscapularis tears were analyzed using the Constant Score, American Shoulder and Elbow Society Index (ASES Index) and postoperative integrity was determined through magnetic resonance imaging. Results: The average clinical outcome scores and strength were all improved significantly at the time of the final follow-up. The constant shoulder score improved from 41.5 to 81.3 points (P<0.05) compared to before surgery and ASES index improved from 46.4 to 89.6 points (P<0.05) postoperatively. Thirteen patients (87%) were satisfied with the result of the treatment. The total tears were significantly more improved by surgery than the partial tears. In 12 of 15 patients (80%) were judged to reveal healed tendon on magnetic resonance imaging at a mean of 13 months postoperatively. The postoperative score was significantly lower for the patients with a failed repair than it was for those with an intact repair (P<0.05). Conclusion: Repair of traumatic isolated subscapularis tears through arthroscopic techniques effectively restores patient function with regard to pain, mobility, strength and postoperative tendon integrity. The postoperative integrity of the repair correlates with the functional results and the total tears were more improved by surgery than the partial tears, but future studies may be needed.

The rupture of the aorta commonly follows major blunt trauma to the thorax. It has markedly increased in recent years, paralleling the rising number of vehicular accidents. The most frequent site of rupture is the area of the isthmus, with the ascending aorta second. The diagnosis of the condition from clinical data is difficult, and aortography is used whenever aortic tear is suspected. We are presenting a case of patient who had intimal tearing of the thoracic aorta with multiple injuries. The patient underwent surgical repair 28 days after injury with left heart [LA-Femoral artery] bypass.

Although the incidence of partial-thickness rotator cuff tears (PTRCTs) was reported to be from 13% to 32% in cadaveric studies, the actual incidence is not yet known. The causes of PTRCTs can be explained by either extrinsic or intrinsic theories. Studies suggest that intrinsic degeneration within the rotator cuff is the principal factor in the pathogenesis of rotator cuff tears. Extrinsic causes include subacromial impingement, acute traumatic events, and repetitive microtrauma. However, acromially initiated rotator cuff pathology does not occur and extrinsic impingement does not cause pathology on the articular side of the tendon. An arthroscopic classification system has been developed based on the location and depth of the tear. These include the articular, bursal, and intratendinous areas. Both ultrasound and magnetic resonance image are reported with a high accuracy of 87%. Conservative treatment, such as subacromial or intra-articular injections and suprascapular nerve block with or without block of the articular branches of the circumflex nerve, should be considered prior to operative treatment for PTRCTs.

We have reported that anterior cruciate ligament (ACL) injury leads to the differential dysregulation of the complement system in the synovium as compared to meniscus tear (MT) and proposed this as a mechanism for a greater post-injury prevalence of post traumatic osteoarthritis (PTOA). To explore additional roles of complement proteins and regulators, we determined the presence of decay-accelerating factor (DAF), C5b, and membrane attack complexes (MACs, C5b-9) in discarded surgical synovial tissue (DSST) collected during arthroscopic ACL reconstructive surgery, MT-related meniscectomy, osteoarthritis (OA)-related knee replacement surgery and normal controls. Multiplexed immunohistochemistry was used to detect and quantify complement proteins. To explore the involvement of body mass index (BMI), after these 2 injuries, we examined correlations among DAF, C5b, MAC and BMI. Using these approaches, we found that synovial cells after ACL injury expressed a significantly lower level of DAF as compared to MT (p<0.049). In contrast, C5b staining synovial cells were significantly higher after ACL injury (p<0.0009) and in OA DSST (p<0.039) compared to MT. Interestingly, there were significantly positive correlations between DAF & C5b (r=0.75, p<0.018) and DAF & C5b (r=0.64 p<0.022) after ACL injury and MT, respectively. The data support that DAF, which should normally dampen C5b deposition due to its regulatory activities on C3/C5 convertases, does not appear to exhibit that function in inflamed synovia following either ACL injury or MT. Ineffective DAF regulation may be an additional mechanism by which relatively uncontrolled complement activation damages tissue in these injury states.

Purpose: The purpose of this study was to analyze the possible contributing factors and surgical results of rotator cuff tears in patients younger than 40 years of age. Materials and Methods: From July, 1996 to February, 2000, twelve patients were available to participate in the study. The average age was 35 years (range, 17 to 40 years) old. Follow-up averaged eighteen months (range, 12 to 55 months). There were eleven men and one women. Each shoulder was evaluated with UCLA shoulder functional assessment, return-to-work status, return-to-sport status, and overall postoperative satisfaction. Results: After operation, eleven patients (92%) reported diminished pain relative to their preoperative level, and ten patients (83%) were improved in shoulder function. eleven patients (92%) exhibited improved strength after operation. nine patients (75%) returned to employment, and six patients (50%) returned to sports activities. Preoperative UCLA score averaged 12 and postoperative score averaged 31. Ten patients (83%) were satisfied with the outcome of their treatment. Conclusion: A traumatic event was the etiology of the rotator cuff tears in patients younger than 40 years. Results of surgical treatment in this younger group were satisfactory.

Subcutaneous emphysema on the head, neck, and pneumomediastinum are, abnomal but well-documented, presence of air in the subcutaneous tissue and mediastinum, and can be diagnosed by palpation of the soft tissues, lateral or crosstable cervical radiograph and upright chest radiograph. The common clinical features of cervical emphysema and pneumomediastinum were facial and cervical swelling, presence of crepitation on palpation of the soft tissue, and retrosternal pain. Subcutaneous emphysema may arise from use of high-speed air turbine drills, facial trauma, trachea bronchial tear, endotracheal intubation, mechanical ventilation, chest injury, tracheostomy, following Lefort I osteotomy, and spontaneously. Symptoms of subcutaneous emphysema and pneumomediastium are generally self-limiting and eventually subside with conservative therapy. As we report a case of traumatic subcutaneous emphysema and pneumomediastinum after facial injury with clinical presentation and treatment consideration.

Purpose: This study is to analyze the prevalence of various intra-articular lesions in patients with traumatic recurrent anterior dislocation of shoulder over 40 years and suggest clinical implications for treatment. Materials and Methods: We retrospectively studied 16 cases that underwent surgical treatment for recurrent anterior dislocation of shoulder from January 2001 to May 2009. There were 9 males and 7 females, and the mean age was 52.7years. We carried out arthroscopic exam for all patients based on standard protocol, which included labrum, capular lesion, cuff, bony lesions. Results: All 16 cases showed Hill-Sachs lesion, 3 patients (19%) had bony Bankart lesion, 6 patients (38%) had labral tear. Capsular tear were found 15 patients (94%). Twelve (75%) had ruptured supraspinatus and 5 (31%) had subscapularis tear. Only one (6%) had SLAP lesion. Conclusion: There was relatively higher incidence of capsular and rotator cuff tears in patients over age 40 years. Preoperative planning to address these lesions is highly recommended.
