An indirect reduction through the bicipital groove and allogenic iliac tricortical bone graft was performed as a treatment for a large Hill-Sachs lesion with a rotator cuff tear in an acute traumatic shoulder joint dislocation in an elderly patient. Six months after surgery, the rotator cuff healing and bone union were confirmed. The patient also showed satisfactory clinical results with 95 points of the American Shoulder and Elbow Surgeons (ASES) shoulder score and active range of motion with 155° flexion, 120° abduction, and 70° external rotation and 30° internal rotation at 90° abduction. The surgical method can be considered for a large Hill-Sachs lesion with rotator cuff tear in an acute traumatic shoulder joint dislocation in elderly patients.

Purpose: We reported the results of arthroscopically assisted lateral release and medial imbrication for the recurrent patella dislocation. Materials and Methods: Twenty patients (20 knees) underwent arthroscopically assisted surgery for the recurrent patella dislocation. There were 4 males and 16 female. The average age was 20.2 years. All patients had definite trauma history and average follow-up period was 19 months. The surgical results were evaluated according to the Lysholm knee score and the Kujala score. The congruence angle and lateral patellofemoral angle were measured on plain radiograph and the tibial tubercle-trochlear groove distance was calculated on computerized tomography. Results: The median value of preoperative congruence angle was $16.5^{\circ}$ (range, $0.0{\sim}+34^{\circ}$) and the average final follow-up was $-6.4^{\circ}$ (range, $-19{\sim}10^{\circ}$) with statistically significant improvement (p=0.025). The median value of preoperative Lysholm knee score was 70 (range, 63~81) and the final follow-up score had changed to 88 (range, 80~95) with statistically significant improvement (p=0.0341). The median value of preoperative Kujala score was 72 (range, 65~80) and the average final follow-up score showed 87 (range, 80~92) with statistically significant improvement (p=0.024). Recurrent dislocations after surgery occurred in 2 cases, one case which showed positive "thumb to forearm test" had been treated with medial patellofemoral ligament reconstruction. Conclusion: Arthroscopically assisted lateral release and medial imbrication for recurrent patella dislocation without bony malaligmenent showed the effective treatment, but would be inappropriate for the patients with the generalized joint laxity.

A 1 year 4 months old, male Poodle was presented with a history of non weight bearing lameness and pain of the right forelimb by trauma. Orthopedic examination and radiographs were revealed medial shoulder luxation and scapular fracture. Biceps tendon was translocated to the lesser tubercle and secured to the humerus. Despite of it could be a potential cause of degenerative change of the joint, a favorable result was achieved for more than 3 years follow-up.

We evaluated the change of quadriceps angle (QA) after tibial tuberosity transposition. Twenty-nine animals and 37 limbs of the total 62 case possibilities qualified for this study. The preoperative QA was $24.02{\pm}4.02$ in grade 2, $26.08{\pm}5.66$ in grade 3 and $30.25{\pm}7.41$ in grade 4. The postoperative QA was $21.25{\pm}3.24$ in grade 2, $19.16{\pm}3.92$ in grade 3 and $19.72{\pm}7.30$ in grade 4. The postoperative QA for all grades significantly decreased when compared with the preoperative QA (P < 0.05). However, the postoperative QA values were not within the normal range, although the dogs' prognosis remained good during the 4-month follow-up period. These results suggest that postoperative QA outside of the normal range may be allowed clinically.

Viable cells of periodontal ligament would be an important factor for the successful replantation of an avulsed tooth. Therefore, it is critical to choose the storage medium for the preservation of traumatically avulsed teeth. Growth factors and hormones could be considered for the therapeutic application of the maintenance of viable periodontal ligament fibroblasts (PDLFs). Epidermal growth factor (EGF) has been suggested as an important player for the regeneration and wound healing process on other tissues. Therefore, EGF was evaluated for the therapeutic application on avulsed teeth. In addition, the synergic effect of EGF with tri-iodothyronine (T3) and heparin-binding epidermal growth factor-like growth factor (HB-EGF). The cell proliferation of PDLFs was determined by MTT assay and increased dose-dependently up to 10 ng/ml in the presence of EGF. Maximum cellular growth was shown at the concentration of 10 ng/ml EGF. Also, EGF promoted the wound healing of PDLFs examined by in vitro wound healing assay. Combined effects of EGF with T3 or HB-EGF on the proliferation of PDLFs were also studied. Interestingly, EGF showed the synergic effect on the proliferation of PDLFs with T3 and HB-EGF. To find out the mechanism of the synergic effect of EGF and T3, the effect of T3 on the expression of endogenous EGF receptor was determined by RT-PCR. The result was that T3 enhanced the expression of EGF receptor in PDLFs. It suggested that EGF might be a good choice for a therapeutic application, which can be used as combination with T3 and HB-EGF.

Purpose: The current study reports the clinical results of total elbow arthroplasties (TEA) which were Performed on patients with poor clinical and radiological results after initial surgeries for elbow fractures or dislocations. Materials and Methods: The clinical outcomes of twelve consecutive patients who underwent TEA after failed surgeries for elbow fractures or dislocations from january, 1995 to December, 2005 were evaluated. The initial diagnoses were distal humeral fractures in 8 cases and fracture-dislocations in 4 cases. The Mean period from the initial operations to the TEAs was 12 months. The mean folloow up period after TEA was 43 months. Results: The mean range of motion, in terms of active extension, activeflexion, supination, and pronation, improved from $14.2^{\circ}$, $96.7^{\circ}$, $50.8^{\circ}$ and $53.3^{\circ}$ to $5.4^{\circ}$, $122.1^{\circ}$, $63.3^{\circ}$ and $67.5^{\circ}$, respectively (p<0.05). RAdiolucent lines were found in 3 cases, which were 1 case of type 3, and 2 cases of type 4. All three loosening cases underwent revision TEAs. The mean postoperative Mayo elvow performance score was 79 point. There were 6 cases of excellent, 2 cases of good, and 4 cases in poor. Conclusion: Good clinical results were obtained after TEA performed in failed surgeries for elbow fractures of dislocations.
