Purpose: To evaluate the result and complication of treatment using Locking Compression Plate (LCP) for fracture of proximal humerus. Materials and Methods: Between 2004 and 2006, 21 patients with two-part and three-part fractures of the proximal humerus were treated by LCP fixation. Their average age was 54.9 years. Postoperative mean follow-up period was 22.9 months. The reduction was qualified and complication were assessed with final radiographs. The functional outcome was evaluated by Neer's rating system. Results: By Neer's functional evaluation, mean score of shoulder function was 86.3 and 18 case (86%) had excellent or satisfactory results. There was one case of nonunion but no infection or avascular necrosis of the humeral head. No correlation was found between the final result and the type of fracture, age, gender or quality of reduction. Conclusion: We obtained satisfactory result of LCP fixation for fracture of proximal humerus in this study. LCP fixation for proximal humerus fracture is a reliable method to obtain satisfactory reduction, rigid fixation and early exercise.

Purpose : The purpose of this study was to evaluate the functional outcomes of one-part fracture of the greater tuberosity that had been treated either by a conservative treatment or an operative approach. Materials and Method: Eighteen shoulders in 18 patients who had an one-part fracture of the greater tuberosity of the proximal humerus were managed, and the average follow-up period was 4 years and 10 months (range, 1 year to 8 years 6 months). Results: According to Neer's criteria for evaluation of results, in the group of 13 patients managed nonoperatively, the results were good or excellent in ten patients, fair in one, and poor in two. In the group managed operatively, the results were excellent in all five patients. Conclusion: If the displacement of the fragment is more than 5mm in young active patients, and more than 3mm especially in athletes and heavy laborers involved in overhead activity, the fragment should be mobilized, repaired and fixed into its original bed or a little bit inferolaterally with multiple heavy non-absorbable sutures, tension band technique, or cancellous screws and washers. We would suggest that the patients showing one-part fracture of the greater tuberosity of the proximal humerus should be evaluated individually.

Background: Proximal humerus fracture is considered to be the third most common fracture for patients aged 65 years or older. Conservative treatment has been known to treat most of humerus fracture. However, fractures with severe displacement or dislocation may require surgical treatment. Intramedullary fibular allograft with a locking plate is frequently used in patients accompanying medial metaphyseal disruption. In this study, author intends to evaluate clinical and imaging results based on patients who underwent surgical treatment using fibular allograft with a locking plate. Methods: This study is conducted prospectively at Wonju Severance Christian Hospital, targeting patients who previously underwent surgical treatment using open reduction and intramedullary fibular allograft with a locking plate between 2011 and 2015. A total of 26 patients were evaluated on the following: postoperational clinical assessment measuring Constant score, American Shoulder and Elbow Society (ASES) score, and the Disabilities of the Arm, Shoulder and Hand (DASH) score. Postoperational imaging assessments are evaluated via measuring the neck-shaft angle. The study subject were Neer classification type 3, 4 proximal humerus fracture cases with disrupted medial hinge and having cortical comminution in the region of the surgical neck. Results: The average period of progression was 22.5 months, and the average age of patients was 72.6 years. At the final follow-up, the average Constant, average ASES, and average DASH scores were 80.1, 78.5, and 20.6 respectively. The average neck-shaft angle was $127.5^{\circ}$. Conclusions: In conclusion, fibular allograft augmentation with a locking plate showed satisfying results in both clinical and imaging studies.

We report a case of recurrent shoulder dislocation and combined proximal humerus fracture in neurofibromatosis type I. A twenty-year-old male patient with known neurofibromatosis type I presented with right shoulder dislocation and proximal humerus fracture following a minor trauma. His injured arm also had large plexiform neurofibromas on the elbow, and the dislocation of the shoulder joint was proven to be recurrent. Bony deformation of the humerus and scapula were revealed on X-ray and computed tomography, as well as multiple neurofibromatic changes of the deltoid and periscapular muscles were noted on magnetic resonance imaging. Open reduction and capsular reconstruction were performed and humeral fracture was stabilized with a reconstruction plate. Satisfactory union and functional result were achieved and the dislocation did not recur until the 7-month followup after the procedure. Recurrent shoulder dislocation and combined proximal humerus fracture in neurofibromatosis type I are rare complications. However, it should still be considered in the orthopaedic evaluation process of the diseases.

Falling related injuries are categorized as the most serious and common medical problems experienced by the elderly, hip joint fracture, one of the most serious consequences of falling in the elderly, occurs in only about 1% of falling. Nevertheless, hip fracture accounts for a considerable part of the disability, death, and medical costs associated with falling. In this study, we considered the impact angle and displacement rate in falling as another factor affecting femoral strength. Using a fresh-frozen human femur, we developed system to simulate the falling condition and then conducted the experiments changing the impact angle (0$^{\circ}$, 15$^{\circ}$, 30$^{\circ}$) of proximal femur. Also, in order to analyze the relative risk due to falling to normal situation in proximal femur, we did the static test simulating the two-legged stance condition. The results showed that the change in impact angle affected the strain distribution in proximal femur, and that a large deformation in femoral neck than in other sites. Furthermore despite low impact velocity, a large deformation in proximal femur occurred in the impact test and different strain distribution was observed compare to the static case.

The direction of the applied load and displacement rate on the femur during falls may be an important factors in the etiology of hip fractures. Nonetheless, previous studies did not consider these two factors simultaneously for falling condition. Therefore, in the present study, an impact test system is developed to simulate the falling condition and the influence of impact angle on the deformation pattern changes of proximal femur is investigated. The results showed that a slight variation in impact angle quite affects deformation pattern of the proximal femur. Along with bone mineral density and trabaecular morphology, the impact angle can be another important factor affecting the structural capacity of the proximal femur.

The aim of this study was to observe the effectiveness of Korean Medicine treatments on pain reduction of patients who were diagnosed hip fracture - Acetabulum and Proximal Femur. We reviewed the 17 patients' records who had admitted to Daejeon Korean Medical hospital and diagnosed fracture of acetabulum or proximal femur bones from January 1, 2011 to April 30, 2020 during the admission retrospectively. Statistical analysis was done using the IBM SPSS statistics 25 program. We measured Numeric Rating Scale to evaluate the treatment's efficacy. Korean Medicine treatments reduced median of Numeric Rating Scale reduced statistically significantly from 6.00 to 3.00(p<0.05). During the admission, patients didn't experience the side effects of Korean Medicine treatments. In conclusion, these results implied that Korean medicine treatments showed a positive effect on pain reduction of hip fracture patients. Further research is required to confirm the effectiveness of Korean Medicine treatments.

To purpose of this study was to evaluate clinical results between rheumatoid arthritis shoulder cases and traumatic proximal humerus fracture cases. Fourteen patients who had been shoulder hemiarthroplasties between March 1991 to July 1996, six had rheumatoid arthritis and eight had comminuted proximal humerus fracture by the various trauma. Neer II prothesis were implanted in twenty cases and global prothesis were implanted in two cases. The follow up period was 15 months to 36 months. To evaluate this study, we used the UCLA shoulder rating. We were able to follow up thirteen cases for more than fifteen months, of which five cases had excellent, five cases had good, two cases had fair and one case had poor. And the results were better for patients with rheumaroid arthritis than for patients with trauma.
