Leadership perspectives in multidisciplinary team meetings; observational assessment based on the ATLAS instrument in cancer care.

OBJECTIVES: High-quality leadership and chairing skills are central components in team performance during multidisciplinary team (MDT) meetings. We hypothesized that the recently developed A Tumor Leadership Assessment inStrument (ATLAS) could provide relevant information to support more detailed insights into MDT chairing and leadership aspects of relevance for team feedback and targeted improvements. MATERIALS AND METHODS: The observational assessment instrument ATLAS rates chairing and leadership skills during MDT meetings in 12 predefined domains that include e.g. time management, case prioritization, team involvement, discussion climate and clarity of treatment recommendations. We used ATLAS to prospectively assess 33 MDT meetings in neuro-oncology, sarcoma and hepatobiliary cancer. RESULTS: The aspects time management, effective case prioritization and provision of clear treatment plans were found to be well-functioning, whereas facilitatation of case discussions, encouragment of team member contributions, keeping the meeting focused and ability to summarize case discussions showed variable and partly weak results. CONCLUSION: We conclude that the ATLAS instrument effectively captures various aspects of MDT leadership and chairing skills. It may thereby provide relevant information to prioritize initiatives that support and develop effective teamwork and decision-making during MDT meetings.

Surgical resection of osteoid osteoma and osteoblastoma of the spine.

Intraoperative radiographic guidance has traditionally been utilized in orthopedic surgery through 2-D navigation with the C-arm and recently with 3-D navigation with the O-arm. The aim of this study was to describe the outcome of surgical treatment of spinal osteoblastoma and osteoid osteoma with the utilization of the O-arm and conventional C-arm guidance. This is a retrospective cohort study of patients with spinal osteoid osteoma and or osteoblastoma who were treated at our institution between 2002 and 2011. Seventeen patients were examined in this study including seven with spinal osteoblastoma and 10 with spinal osteoid osteoma. The mean age of the patients at surgery was 11.5±3.9 years. The O-arm was used in seven patients and the C-arm in 10 patients. The C-arm failed to identify the tumor in one case and needed transport to perform a computed tomographic-scan. The length of surgery was shorter when the O-arm was used, especially in the osteoblastoma group. Thirteen patients were pain free at the last follow-up visit and two patients developed recurrence. Radiographs at the last follow-up did not show signs of vertebral instability following tumor resection. Safe and effective localization of spine tumors and confirmation of tumor removal during surgery was achieved by intraoperative radiographic guidance specifically with the O-arm 3-D navigation system.

Radial Neck Fractures in Children and Adolescents: An Examination of Operative and Nonoperative Treatment and Outcomes.

BACKGROUND: Although most pediatric radial neck fractures can be treated with either immobilization alone or closed reduction and immobilization, a small subset result in permanent loss of motion despite surgical management. We sought to characterize the most problematic fractures and correlate final outcomes with both presenting fracture characteristics and the reduction achieved through surgical intervention. METHODS: One hundred ninety-three consecutive children with a radial neck fracture, satisfactory initial treatment data, and follow-up range-of-motion (ROM) data presenting between 1999 and 2012 to our level 1 trauma center were evaluated. The O'Brien classification was used to evaluate angulation on radiographs. Final ROM outcomes were categorized into excellent, good, fair, and poor. ROM data were not used in the operative group if follow-up was <12 weeks (<6 wk in the nonoperative group) or if there was no follow-up after cast removal. RESULTS: Thirteen percent of all patients presenting with radial neck fractures required operative treatment (average age 9.1 y). Of patients treated operatively with adequate ROM data, 26.4% healed with fair or poor outcomes. Patients requiring open management were of older average age (average 10 y old, P=0.02) and had a significantly greater risk of a fair or poor ROM outcome than those treated with closed operative techniques (P=0.02). Patients treated nonoperatively were of a younger average age than those in the operative cohort (8.2 vs. 9.1 y, P=0.03). Patients treated operatively were more likely to develop complications (P=0.004); however, presence of a complication was not predictive of fair or poor outcomes in either the operative (P=0.117) or nonoperative (P=0.264) groups. CONCLUSIONS: Older children are more likely to have more severely displaced radial neck fractures requiring open surgical management, thus resulting in a greater risk of fair or poor outcomes. In the series as a whole, more complications were seen when operative management was required. Final outcomes were not shown to be significantly related to preoperative displacement, postoperative reduction, presence of associated injuries, energy of injury, or treatment complications.

Chondroblastoma and chondromyxoid fibroma.

Chondroblastoma and chondromyxoid fibroma are benign but locally aggressive bone tumors. Chondroblastoma, a destructive lesion with a thin radiodense border, is usually seen in the epiphysis of long bones. Chondromyxoid fibroma presents as a bigger, lucent, loculated lesion with a sharp sclerotic margin in the metaphysis of long bones. Although uncommon, these tumors can be challenging to manage. They share similarities in pathology that could be related to their histogenic similarity. Very rarely, chondroblastoma may lead to lung metastases; however, the mechanism is not well understood.
