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.

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.

Background: The purpose of this study was to investigate the clinical and radiological outcomes of locking plate fixation with fibular strut allograft to manage unstable osteoporotic proximal humerus fractures. Methods: We retrospectively reviewed 15 patients who underwent open reduction and locking plate fixation with fibular strut allograft for osteoporotic proximal humerus fracture between July 2011 and June 2015. For functional evaluation, we evaluated visual analogue scale (VAS) pain score, American Shoulder and Elbow Surgeons (ASES) score, University of California Los Angeles (UCLA) shoulder score, and active range of motion. For radiological evaluation, shoulder true anteroposterior (AP) and AP in $20^{\circ}$ external rotation, as well as the axillary view were taken at two weeks, six weeks, three months, six months, and one year. And the neck-shaft angle was measured on the AP view in $20^{\circ}$ external rotation view. Results: At the one-year follow-up, mean VAS pain score and all shoulder scores, including ASES score and UCLA shoulder score, exhibited satisfactory clinical outcomes. All patients obtained bone union between three and six months post-procedure. Moreover, the mean immediate postoperative neck-shaft angle was $138^{\circ}{\pm}4^{\circ}$, and at one-year follow-up, the neck shaft angle was $137^{\circ}{\pm}5^{\circ}$. There was no significant difference between the preoperative and postoperative values (p=0.105). Conclusions: For the unstable two-part and three-part osteoporotic proximal humerus fractures with medial calcar comminution, the use of fibular strut allograft with locking plate fixation was effective in maintaining the initial status of reduction and exhibiting the satisfactory functional and radiological outcomes.

Purpose : To evaluate functional results and study factors influencing results after humeral hemiarthroplasty for comminuted fractures of the proximal humerus. Materials and Methods: We reviewed 12 patients with average follow-up period of 23 months(12 to 42). The proximal humeral fractures consisted of one anatomical neck fracture, five three-part and six four-part fractures or fracture-dislocations. Constant score and Compito et al' evaluation system were used for clinical assessment. Statistical analysis was done with the Wilcoxon test. Results: Six cases of anatomical neck, three-part fractures or fracture-dislocations showed 61 points on the average Constant score and three unsatisfactory results on the Compito et al' evaluation; Six of four-part fractures or fracture-dislocations showed 51 points and three unsatisfactory results. There were 59(two unsatisfactory) for five non-associated dislocation and 53(four unsatistactory) for seven associated dislocation; 66(one unsatisfactory) for three under 60 years and 41(five unsatisfactory) for nine over 60 years; 67(two unsatisfactory) for seven tuberosity union and 41(four unsatisfactory) for five tuberosity non-union or resorption; 58(four unsatisfactory) for ten early operation within two weeks and 43(all unsatisfactory) for two delayed operation; and 18(unsatisfactory) for one case of a accompanied rotator cuff tear. Conclusion: We concluded that tuberosity union was important factor influencing the results. Also, we thought that age, timing of operation and accompanied rotator cuff tear could be influenced to results.

Background: The purpose of this study was to evaluate the clinical and radiographic outcomes of internal fixation with locking T-plates for osteoporotic fractures of the proximal humerus in patients aged 65 years and older. Methods: From January 2007 through to December 2015, we recruited 47 patients aged 65 years and older with osteoporotic fractures of the proximal humerus. All fractures had been treated using open reduction and internal fixation with a locking T-plate. We classified the fractures in accordance to the Neer classification system; At the final follow-up, the indicators of clinical outcome-the range of motion of the shoulder (flexion, internal rotation, and external rotation) and the presence of postoperative complications-and the indicators of radiographic outcome-the time-to-union and the neck-shaft angle of the proximal humerus-were evaluated. The Paavolainen method was used to grade the level of radiological outcome in the patients. Results: The mean flexion was $155.0^{\circ}$ (range, $90^{\circ}-180^{\circ}$), the mean internal rotation was T8 (range, T6-L2), and the mean external rotation was $66.8^{\circ}$ (range, $30^{\circ}-80^{\circ}$). Postoperative complications, such as plate impingement, screw loosening, and varus malunion were observed in five patient. We found that all patients achieved bone union, and the mean time-to-union was 13.5 weeks of the treatment. The mean neck-shaft angle was $131.4^{\circ}$ at the 6-month follow-up. According to the Paavolainen method, "good" and "fair" radiographic results each accounted for 38 and 9 of the total patients, respectively. Conclusions: We concluded that locking T-plate fixation leads to satisfactory clinical and radiological outcomes in elderly patients with proximal humeral fractures by providing a larger surface area of contact with the fracture and a more rigid fixation.

Purpose: This study is to analyze the result and complications of internal fixation with T-plate for two-part fracture of the neck of the humerus. Materials and Methods: The clinical results of fourteen patients who had been performed with this method mentioned above were reviewed. Their average age was 49.6. Postoperative mean follow up period was 24.1 months. Radiological evaluation was done by Kronberg's and shoulder function by Neer's. Results: By Kronberg evaluation, nine cases were good, two cases acceptable and three cases poor. By Neer's, mean score of shoulder function was 77.6 and 4 cases were excellent, one satisfactory, five unsatisfactory and four failure. The complications were the sfiff shoulder, loss of reduction and avascular necrosis of humeral head. Conclusion: In this study, there were differences according to the age. And we obtained an unsatisfactory result in patients over 50 years old. We consider that in patients over 50 years old, the differences were due to the muscle weakness through wide surgical approaches, postoperative implant loosening or the stiffness caused by poor rehabilitation.

To report the fracture of proximal humerus in the lateral anchor site after suture bridge repair. A 57-year-old female patient with shoulder pain on the right-side was admitted through the emergency room following a car accident. Seven weeks before the accident, the patient had undergone surgery at a different hospital for the repair of supraspinatus tendon rupture on the right-side via suture bridge technique. Humerus surgical neck fracture was confirmed by X-ray, and proximal humerus fracture at the anchor site was confirmed by magnetic resonance imaging. Following 7 months of conservative treatment resulted in satisfactory bone union and motion of the shoulder joint. We report the need of close observation during and after the arthroscopic repair of the rotator cuff in patients with osteoporosis.

Oncocytic neoplasm of the head and neck region accounts for approximately 1% of all salivary gland tumors, but only 5% of oncocytic neoplasm is malignant. Oncocytic carcinoma arising in the submandibular gland is exceedingly rare. We encountered a sixty seven-year-old male patient who presented with multiple mass in the right neck. Fine needle aspiration biopsy revealed a salivary gland tumor of predominantly oncocytic form, and a differential diagnosis included oncocytic adenoma or mucoepidermoid carcinoma. A right submandibular gland resection and modified radical neck dissection were performed. Histologically, the tumor cells showed nuclear pleomorphism, and stromal invasion, which were compatible with oncocytic carcinoma. After surgery, the entire neck region was irradiated. Seventeen months after the initial surgery, multiple metastases to the bone and lung were detected from the incidental pathologic bone fracture of the right humerus; palliative chemotherapy was performed to resolve this. We report a case of oncocytic carcinoma in the submandibular gland with a review of literature.
