  • The importance of inferomedial support in the Hot Air Balloon technique for treatment of 3-part proximal humeral fractures.
    Journal of shoulder and elbow surgery, 2011
    Co-Authors: Jin-young Park, Jung-han Kim, Sang-hoon Lhee, Seung-jun Lee
    Abstract:

    Hypothesis Inferomedial support may affect the results of the Hot Air Balloon technique for the treatment of displaced, 3-part fractures of the proximal humerus. Methods Forty-three patients with displaced, 3-part fractures of the proximal humerus treated with the Hot Air Balloon technique between 1995 and 2007 were included in the study. All patients were classified into 4 subgroups based on the presence or absence of medial buttress restoration and inferomedial screw insertion (R+, restored with inferomedial screw; R–, restored without inferomedial screw; NR+, non-restored with inferomedial screw; and NR–, non-restored without inferomedial screw). Assessment of radiologic and clinical outcome among subgroups was based on evaluation of neck-shaft angle, American Shoulder and Elbow Surgeons score, and Neer score. Results The mean follow-up duration was 65 ± 29.7 months. The change in the neck-shaft angle in the R+, R–, NR+, and NR– groups was 3°, 2°, 3°, and 11°, respectively. The mean American Shoulder and Elbow Surgeons scores in the R+, R–, NR+, and NR– groups were 91 ± 4.8, 86 ± 5.4, 85 ± 1.9, and 77 ± 5.8, respectively. The mean Neer scores in the R+, R–, NR+, and NR– groups were 92 ± 4.3, 88 ± 4.0, 87 ± 2.1, and 76 ± 8.2, respectively. Conclusions Medial buttress restoration and inferomedial screw insertion affect bone-nail construct stability and clinical outcomes.

  • open intramedullary nailing with tension band and locking sutures for proximal humeral fracture Hot Air Balloon technique
    Journal of Shoulder and Elbow Surgery, 2006
    Co-Authors: Jin-young Park
    Abstract:

    To reduce complications and increase fixation after the internal fixation of proximal humeral fractures, interlocking intramedullary nailing and tension-band and locking sutures were used simultaneously, and their results are reviewed. Twenty-six consecutive patients who underwent open intramedullary nailing with tension-band and locking sutures for proximal humeral fractures were selected. The mean follow-up period was 39 months. With regard to the functional evaluation, the mean Neer score was 90 points and the mean American Shoulder and Elbow Surgeons score was 85. When patients were divided into those aged less than 65 years and those aged 65 years or greater and into those with 2-part fractures and those with 3-part fractures, postoperative pain, the American Shoulder and Elbow Surgeons score, and the Neer score showed no difference between the 2 groups. Open intramedullary nailing accompanied by tension-band and locking sutures for proximal humeral fractures shows sufficient fixation in older patients, and therefore, good postoperative shoulder function can be expected.

  • constructivist physics learning in an immersive multi user Hot Air Balloon simulation program ihabs
    International Conference on Computer Graphics and Interactive Techniques, 2003
    Co-Authors: Wong Lai Kuan, Chee Yam San
    Abstract:

    This paper describes and discusses an immersive multi-user Hot Air Balloon Simulation (iHABS) project that allows students to experience virtual Hot Air Ballooning. The iHABS project enables students to pilot a Hot Air Balloon as well as learn fundamental physics principles in a fun, exciting, engaging, and collaborative setting.We briefly survey the use of Hot Air Ballooning in physics teaching and the use of VR technologies in support of learning. We then discuss the pedagogical support provided by iHABS. Next, we proceed with a detailed description of the iHABS system followed by a discussion on the design of interaction techniques, the system design and its implementation.
