The purpose of the study is to compare the clinical results of isolated Bankart repairs with the clinical results of Bankart repairs when performed with concomitant SLAP repairs. Methods: The patients who underwent arthroscopic surgery for treatment of anterior glenohumeral instability were evaluated retrospectively. Group 1 consisted of 19 patients who had arthroscopic SLAP repair together with Bankart repair. The mean age of the patients was 23. Group 2 consisted of 38 patients who underwent isolated Bankart repair. The mean age was 24. Knotless anchors were used in both groups. Results: The mean follow-up was 34 months (range: 26-72). In group 1, the mean preoperative Constant score was 84 (range: 74-90, standard deviation (SD): 5.91) and Rowe score was 64.1 (range: 40-70, SD: 8.14). In group 2, the preoperative Constant score was 84.4 (range: 70-96, SD: 5.88) and Rowe score was 60 (range: 45-70, SD: 7.95). In group 1, the postoperative mean Constant score raised to 96.8 (range: 88-100, SD: 2.91) and the mean Rowe score raised to 92.3 (range: 85-100, SD: 5.17). In group 2, the postoperative mean Constant score was 94.9 (range: 88-100, SD: 3.70) and the mean Rowe score was 94.2 (range: 80-100, SD: 4.71). The difference between the scores of two groups was insignificant (p > 0.05). When the numbers of redislocations and range of motion were compared, no significant difference was found (p > 0.05). Conclusion: Accompanying SLAP repair in surgical treatment with Bankart repair for shoulder instability does not affect the results negatively. Properly repaired labral tears extending from anterior inferior to the posterior superior of the glenoid in instability treatment have the same outcome in overall results as repaired isolated Bankart lesions.

Specifically, the injury resulted in loss of first metatarsal without injury to the medial cuneiform or proximal phalanx, fracture of the third metatarsal, and a 5-cm × 9-cm soft tissue defect overlying the dorsomedial aspect of the right foot. After debridement and daily wound care, the defect was subsequently reconstructed using a free osteocutaneous fibular graft. Approximately 6 months after reconstructive surgery, the patient returned to his job without pain, and his pedogram showed almost equal weightbearing distribution on both feet.

We present here a case involving a type IIIC open tibial fracture with massive loss of the entire tibial diaphysis, which we treated by performing acute tibialization of the fibula after revascularization of the posterior tibial artery in a single-stage emergency operation.

Nineteen patients (21 legs) underwent replantation-revascularization surgery. At least Chen Grade II functional level was the aim. A limb salvage operation was performed in 21 legs in 19 patients (18 male, 1 female). The mean age was 28.5 years (range: 11 to 42 years). Six legs in four patients presented with total amputation, and 15 legs in 15 patients had Gustilo Type III C open fractures. A successful replantation/revascularization was performed in 20 legs, with a Chen Grade I and Grade II functional outcome in 3 and 17 legs, respectively. None of these patients were eligible for salvage operation according to currently used scoring systems. Limb-preserving surgery performed upon the assessment of local and general conditions of the patients with traumatic below-knee amputations or Gustilo Type III C open fractures seems to be a viable therapeutic option that can serve to achieve Chen Grade II functional level in most patients.

Methods: Sixty-four femoral arteries of 32 Sprague-Dawley rats were used in this study. The animals were divided equally into 4 groups with 16 anastomoses in each group. The arteries (0.8-1.0 mm diameter) were anastomosed by using the continuous horizontal mattress suture technique in group I, interrupted horizontal mattress suture technique in group II, simple interrupted suture technique in group III, and simple continuous suture technique in group IV. At the end of the anastomosis time, leakage, and patency were assessed and graded in all groups. On the 14th day after surgery the rats were killed and 5 patent specimens from each group were examined under light microscopy for histology. One specimen from each group was prepared for scanning of the endothelial surface under electron scanning microscopy. Results: Group I anastomoses were performed the most quickly. Groups I and III anastomoses had 100% patency rates. Under light microscopy the edge eversion was apparent consistently and under electron microscopy all endothelial surfaces were intact and no suture material was seen in groups I and II. In group III some suture material was covered by endothelial cells and lumen surfaces were torn; endothelization also was rough compared with groups I and II. In group IV suture material was seen in the lumen because of a loose suture knot. The endothelium also was not regular. Conclusions: The horizontal mattress suturing technique is the only technique in which the suture material never contacts the lumen. Continuous horizontal mattress suture technique is superior to the other microvascular procedures and is the safest and fastest procedure for microvascular anastomosis in rats. (

The study included 24 trained young male athletes and 22 healthy sedentary male subjects. Athletes who participated in the study were from different sports branches and have been regularly exercising for at least 2 years. Serum leptin levels were determined by RIA. VO2max levels were identified during maximal exercise. Lactic acid levels were identified one minute before and one minute after exercise from the fingertip by Pro-lactate kit. As a result of the tests, although BMI values of trained young male athletes and healthy males were close to each other, leptin levels were significantly lower (p<0.01), VO2max values were significantly higher (p<0.01) and test periods were significantly longer (p<0.001) in the former. In conclusion, regular exercise, by reducing body fat percentage, suppresses serum leptin levels.

We present three patients with different tumors at the carpal tunnel as a cause of triggering. All patients were treated with local excision.
