Purpose : This study was performed to evaluate the presence and severity of Hill-Sachs (HS) lesions on MR arthrography (MRA) of shoulder in patients with Bankart lesions following anterior dislocation and to investigate their relationship with Bankart lesions and frequency of dislocations. Materials and Methods: 86 MRA of shoulder were evaluated in patients with arthroscopic Bankart repairs following anterior dislocations. The largest surface length of HS lesion on MRA and extent of Bankart lesions on arthroscopy were measured. Relationships between length of HS lesions and extent of Bankart lesions and frequency of dislocations were assessed. Results: HS lesions were identified on MRA in 78 patients. The largest surface length of HS lesion ranged from 9.3 mm to 29.6 mm (mean, 18.8 mm). The extent of Bankart lesion ranged from one to six o'clock extent (mean, 4.25 o'clock extent). Three patients had single dislocation and the other 75 patients had recurrent dislocations (mean 24.5 times). The largest surface length of HS lesions was positively correlated with extent of Bankart lesions (p = 0.001, r = 0.37), but not with frequency of dislocation. Conclusion: HS lesion was very common in patients with Bankart lesion. The severity of HS lesions was correlated with extent of Bankart lesions.

This study histologically assessed the effect of topical alendronate application on periodontal healing in replanted teeth in fifty four SD Rats. Upper first molars in rat were extracted and replanted after dried during 15 minutes or 60 minutes in the air. In Group I, all teeth were replanted after 15 minutes of dry storage without any other treatment. In Group II and III, the pulps were removed and all teeth were replanted after soaking 10 min in Hank's balanced salt solution with/without alendronate, followed by 60 minutes of dry storage. the rats were sacrificed after 7, 15 and 30 days. The histological parameters studied were healed PDL, surface inflammatory and replacement resorption, and inflammatory severity. The following conclusions could be drawn from the present investigation. 1. Group I showed lower inflammatory root resorption and inflammation severity rate, compared to Group II and Group III. In Group I there showed effective for reattachment and regeneration of PDL. 2. In Group II, inflammatory root resorption were more severe and faster than other groups. There were extensive root resorption in the rats sacrificed after 30 days. 3 In Group III, there were localized inflammatory resorption in several areas, but extensive resorption did not occur Group III showed increase in root resorption rate, compared to Group I. However this difference was not statistically significant. 4. There were no difference between sacrificed days in replacement root resorption in all groups.

Although uncommonly encountered, knee dislocation is frequently associated with popliteal artery injury. It has been reported that all detected arterial injuries warrant intervention and open surgical management is the standard of treatment. We report here on a case of endovascular intervention for popliteal artery injury in knee dislocation, and then this was treated with ligament surgery with arthroscopic and open procedure.

A 7-year-old, intact female Golden Retriever weighing 38 kg was referred for left coxofemoral joint luxation. On physical examination, pain and crepitus were noted atthe left hip joint during joint extension. Radiological examination revealed coxofemoral joint luxation and mild degenerative bone changes in the left hip joint. We performed minimally invasive arthroscopy-assisted reduction with TightRope$^{(R)}$ as a treatment option; however, the left coxofemoral joint was reluxated after one month postoperatively. We performed cementless total hip replacement (THR) of the luxated left coxofemoral joint. At tenmonths after surgery, the dog could sit, stand, walk normally and jump comfortably without lameness. The thigh girth measurement of the operated limb was 108.6% of the contralateral limb. Based on the present case, THR can be a successful treatment for coxofemoral joint luxation in dogs with failed coxofemoral joint reduction.

In general, most knee dislocations are reduced easily by simple traction. In rare cases, closed reduction of the knee dislocation is attempted, but ruptured ligaments or muscles are stuck in the joints and cannot be reduced. The cases of this irreducible knee dislocation have sometimes been reported. The authors encountered a case of irreducible knee posterolateral rotational dislocation that was not reduced by simple traction and report it along with a review of the literature. This case provides an opportunity for clinicians to examine the clinical considerations when experiencing an irreducible knee dislocation.

A 10-year-old intact female Chihuahua weighing 2 kg was presented for complaint of forelimb lameness with non-weight bearing posture. Greater tubercle was palpated medial to its normal location on palpation and crepitation was intermittent with manipulation. On radiographic examination, left medial scapulohumeral joint luxation was found. Bilateral medial patellar luxations also were found and evaluated as grade III. Surgically, the medial scapulohumeral joint luxation was reduced with transposition of the tendon of the biceps brachii muscle. The patient's gait became normal and non-weight bearing posture was resolved at 6 weeks postoperatively.

Purpose: To evaluate the results of percutaneous lateral release and arthroscopic medial plication for patients with recurrent patella dislocation. Materials and Methods: This study includes the thirty-one cases of patients who have had a surgical operation from March 2001 to March 2008. All the patients had recurrent patella dislocation after trauma history. The average age was 24.2 years old and the average follow up was 47.4 months (minimum 24 months). Results: The preoperative congruence angle, lateral patellofemoral angle, Lysholm score was $24.8^{\circ}$, $-6.2^{\circ}$, 75 points on average respectively. However, the postoperative congruence angle, lateral patellofemoral angle, Lysholm score was improved to normal range: $-2.8^{\circ}$, $10.2^{\circ}$, 95 points on average. Five cases showed the recurrent dislocation after operation. Among them, three cases showed femoral trochlear dysplasia. Conclusion: Percutaneous lateral release and arthroscopic medial plication showed satisfactory results for recurrent patella dislocation with low complication rate. However, in cases with femoral trochlear dysplasia, another surgical treatment may be considered.
