The use of intramedullary helix wire for the treatment of proximal humerus fractures

OBJECTIVE: To present the functional and radiographic outcome 1 and 6 years after application of a new intramedullary fixation device for proximal humerus fractures. DESIGN: Retrospective case series. SETTING: Level II orthopaedic surgery hospital. PATIENTS: Twenty-six consecutive patients (average age 68.9 years) with 2-, 3- and 4-part fractures of the proximal humerus were operated at a single institution. Follow-up was performed after 1 year (26 patients) and 6 years (16 patients). INTERVENTION: All patients were treated with closed reduction and intramedullary helix wires. MAIN OUTCOME MEASUREMENTS: The Constant-Murley score and the University of California Los Angeles (UCLA) score. Clinical complications and radiological posttraumatic arthritis were recorded. RESULTS: The average Constant-Murley score was 70.3 (points) and 70.7 after 1 and 6 years, respectively; the average UCLA score was 27.2 and 31.5 after 1 and 6 years, respectively. Major complications were 4 revisions for 3 secondary fragment displacements and 1 nonunion with partial avascular osteonecrosis in the first postoperative year. Complications were found predominantly in 4-part fractures (3/5, 60%). There were no further complications or progressive posttraumatic arthritis up to 6 years following surgery. CONCLUSION: The helix wire is well suited for displaced or unstable 2- and 3-part proximal humerus fractures. Adequate functional outcome, a low number of implant displacements, a low number of application morbidity, and infrequent implant removals were recorded. The use of this device is not recommended for 4-part fractures.

Effects of geriatric clinical skills training on the attitudes of medical students.

BACKGROUND Physicians' attitudes, knowledge and skills are powerful determinants of quality of care for older patients. Previous studies found that using educational interventions to improve attitude is a difficult task. No previous study sought to determine if a skills-oriented educational intervention improved student attitudes towards elderly patients. METHODS This study evaluated the effect of a geriatric clinical skills training (CST) on attitudes of University of Bern medical students in their first year of clinical training. The geriatric CST consisted of four 2.5-hour teaching sessions that covered central domains of geriatric assessment (e.g., cognition, mobility), and a textbook used by students to self-prepare. Students' attitudes were the primary outcome, and were assessed with the 14-item University of California at Los Angeles Geriatrics Attitudes Scale (UCLA-GAS) in a quasi-randomized fashion, either before or after geriatric CST. RESULTS A total of 154 medical students participated. Students evaluated before the CST had a median UCLA-GAS overall scale of 49 (interquartile range 44-53). After the CST, the scores increased slightly, to 51 (interquartile range 47-54; median difference 2, 95% confidence interval 0-4, P = 0.062). Of the four validated UCLA-GAS subscales, only the resource distribution subscale was significantly higher in students evaluated after the geriatric CST (median difference 1, 95% confidence interval 0-2, P = 0.005). CONCLUSIONS Teaching that targets specific skills may improve the attitudes of medical students towards elderly patients, though the improvement was slight. The addition of attitude-building elements may improve the effectiveness of future skills-oriented educational interventions.
