Proximal humerus fractures are the third most common fractures, totaling 4% to 5% of all fractures. Here, we present the case of a 39-year-old man with a dislocated four-part fracture of the proximal humerus with a huge bony Bankart lesion. Preoperatively, the bony Bankart lesion of the glenoid was not visualized on computed tomography scans or magnetic resonance imaging because the fracture of the proximal humerus was comminuted, displaced, and complex. It was planned for only the humerus fracture to be treated by open reduction and internal fixation using a locking plate. However, a fractured fragment remained under the scapula after reduction of the dislocated humeral head. This was mistaken for a dislocated bone fragment of the greater tuberosity and repositioning was attempted. After failure, visual confirmation showed that the bone fragment was a piece of the glenoid. After reduction and fixation of this glenoid part with suture anchors, we acquired a well-reduced fluoroscopic image. Given this case of complex proximal humerus fracture, a glenoid fracture such as a bony Bankart lesion should be considered preoperatively and intraoperatively in such cases.

Background: There has been lack of epidemiology of proximal humerus fracture using nationwide database in Asia. The purpose of this study was to investigate the incidence of proximal humerus fracture and its mortality following proximal humerus fracture in Korean over 50 years of age. Methods: The Korean National Health Insurance data were evaluated to determine the incidence and mortality of proximal humerus fracture aged 50 years or older from 2008 through 2012. Results: Proximal humerus fracture increased by 40.5% over 5 year of study. The incidence of fracture increased from 104.7/100,000 in 2008 to 124.7/100,000 in 2012 in women and from 45.3/100,000 in 2008 to 52.0/100,000 in 2012 in men, respectively. One year mortality rate after proximal humerus fracture was 8.0% in 2008 and 7.0% in 2012. One year mortality rate were 10.8% for men and 7.0% for women in 2008 and 8.5% for men and 6.4% for women in 2012. Conclusions: Our study showed that the proximal humerus fracture in elderly was recently increasing and associated with high mortality in Korea. Considering proximal humerus fracture was associated with an increased risk of associated fractures and an increased mortality risk, public health strategy to prevent the proximal humerus fracture in elderly will be mandatory.

The purpose of this study was to determine the relationship between rotation of the humerus and the shoulder movement in the sagital, coronal, and diagonal planes. Thirty normal subjects(15 male. 15 female)were tested using Cybex NORMTM Testing & Rehabilitation System (CYBEX Division of LUMEX, Inc., Ronkinkoma, New York). The subjects performed active shoulder flexion, abduction and PNF patterns. The range of motion(ROM) of the glenohumeral joint was measured three times. In order to assure the statistical significance of the results. the independent t-test. and a pearson's correlation were applied of the .05 and .01 level of significant. The results of this study were as follow ;1. There were statistically significant differences between shoulder flexion with humerus medial rotation and shoulder flexion with humerus lateral rotation(p <.01). 2. There were statistically significant differences between shoulder abduction with humerus medial rotation and shoulder abduction with humerus lateral rotation(p <.01). 3. There were statistically significant differences between PNF pattern(flex-abd-ext rot) with humerus medial rotation and PNF pattern with humerus lateral rotation(p < .01).For effective rehabilitation of the shoulder, physical therapists must have correct knowledge of shoulder movements. Physical therapists should consider these results when the goal of treatment is to increase ROM of the shoulder.

Concomitant ipsilateral fractures of the humerus, radius and ulna are uncommon combined injury and are also called "floating elbow". It was found that this injury was usually a result of rather severe trauma and frequently associated injuries to other organ systems. It is controversial in the treatment of the "floating elbow", but the current treatment recommendations are open reduction and internal fixation of both the humerus and the forearm fracture with early initiation of range of motion exercises. The authors reviewed thirteen cases of ipsilateral fractures of the humerus, radius and ulna treated in our clinic from January 1992 to March 1997, and average follow-up period was over 18 months(range, 12 to 36 months). The results obtained were as follows; 1. The most common cause of injury was traffic accident and most common location of fractures was mid-third in both humerus and forearm. 2. The shape of fractures was transverse or comminuted in most cases. 3. The good clinical results were obtained by open reduction and internal fixation of both the humerus and the forearm fracture with early initiation of range of motion exercises. 4. The recovery was affected by the severity of the initial trauma and method of the treatment. 5. According to the Lange and Foster method, the functional result was good in 8 cases, fair in 4 cases and poor in 1 cases.

Purpose: This study examined the effects of the abdominal hollowing technique applied during plank exercises at different shoulder angles between the ground and the humerus on the abdominal muscle activity Methods: The subjects were 36 male volunteers. They were randomized to perform plank exercises or plank exercises using the hollowing technique at 80˚, 90˚, 100˚, and 110˚ between the ground and the humerus. The abdominis muscles were measured using a surface electromyogram. Independent t-tests examined the changes in the activity of these muscles according to the two exercise methods at each angle. The changes in muscle activity were examined according to the selected angles by one-way analysis of variance. Results: The activity of abdominal muscles was investigated according to the angle between the ground and the humerus during the plank exercise. As a result, the muscle activity increased significantly with decreasing angle in the rectus abdominis, external oblique, and internal oblique·transverse abdominis muscles (p<0.05). In terms of the changes in abdominal muscle activity after hollowing plank exercises at the given angles between the ground and the humerus, an increase in angle resulted in a statistically significant increase in the rectus abdominis muscle activity (p<0.05). The activities of the rectus abdominis, external oblique, and internal oblique/transverse abdominis muscles after hollowing plank exercises showed statistically significant increases (p<0.05) compared to those after plank exercises. Conclusion: The hollowing technique and the increase in the angle between the ground and the humerus may be an effective exercise method for increasing the muscle activity of the abdominis muscles.

A common kestrel was admitted to Chungnam wild animal rescue center, having been unable to fly. On the physical examination, the bird was presented with contusion and swelling on its right humerus closed fraction and had pain response. Radiographic examination was explicitly revealed closed fracture on right proximal humerus. Its closed fracture was reduced with tie-in fixator and figure-of-eight tension band, and inserted pins on its right humerus surgery were removed on the $14^{th}$ day after the surgery. As Falco tinnunculus was able to move its wings from Day $21^{st}$ day, its rehabilitation was done at outdoor facility and it was successfully released. Proximal humerus reduction with tie-in fixator and the wire was a success, and this treatment with reference to this study will be surely effective to support the other wildbird's reduction stability.

Purpose : The aim of this study is the assessment of the clinical outcomes after percutanous pinning of unstable two-parts fracture of surgical neck in humerus. Materials and Methods: This study was based on thirteen cases of non-comminuted unstable surgical neck fracture of humerus among 19 cases, which followed-up more than one year. Follow-up averaged 29 months. We treated with percutaneous pinning techniques and assessed clinical outcomes. Functional evaluation was performed using the standard method of research committee of American Shoulder and Elbow Surgeons(ASES). Results: Last follow-up ROM of shoulder joint were 142 degrees of forward elevation, 57 degrees of external rotation, 72 degrees of external rotation in 90 degrees abduction, and T8 of internal rotation. Pain scale was l(range : 0∼3). ASES scores was 86.2(range : 63.3~98.3). Patient satisfaction based on ASES were excellent in 6 cases, good in 5 cases, fair in 1 case, poor in 1 case. A case of fair result was caused by limitation of motion in shoulder joint and poor case was paraplegia patient after traffic accident. Conclusion : Percutaneous pinning is recommended for non-comminuted unstable fracture of surgical neck in humerus.

A 13-year old male dog with right forelimb lameness, invisible swelling, anorexia and mild depression was referred to Veterinary leaching Hospital, College of Veterinary Medicine, Kyungpook National University. On forelimb radiographic views, periosteal and endosteal proliferation and cortical lysis and extremely aggressive and amorphous periosteal reactions were located along the metaphyseal region of the proximal humerus. Cytologic and histopathologic examinations after amputation showed anaplastic mesenchymal cells that produced osteoid changes, poorly differentiated osteoblast and osteoclast. And also, it included the neoplastic cells with large nucleoli, multiple nucleoli that differ in size and cytoplasm with several clear vacuoles. Based on the physical examination and laboratory, radiolographic, cytologic and histopathologic findings, this case was diagnosed as osteosarcoma of the proximal humerus.

Isolated avulsion of the lesser tuberosity of the humerus in adolescent is rare injury. The mechanism of injury is acute forced external rotation and with the arm in abduction which has been reported in children participating in sports such as football, hockey, volleyball, wrestling and skateboarding. The diagnosis is often delayed despite chronic pain and disability. Authors report the unique case of a skeletally immature adolescent Judo player who had an isolated avulsion of the lesser tuberosity of the humerus with the references.
