Purpose:
To evaluate fracture healing, functional outcomes, complications, and mortality associated with rigid cervical collars.
Methods:
Thirty-four patients with <50% odontoid displacement were treated with a rigid cervical collar for 12 weeks (Average age = 84 years). Outcome scores were compared with a group of 40 age-matched control subjects (Average age 79.3).
Results:
At average 14.9-month follow-up, only 6% demonstrated radiographic evidence of fracture healing and 70% had mobile odontoid nonunion. NDI scores indicated only mild disability, pain scores were low, and neither differed significantly from age-matched controls. Mobile odontoid nonunion was not associated with higher levels of disability or neck pain. Mortality rate was 11.8%. Treatment complications occurred in 6% of patients.
Conclusions:
Odontoid nonunion and instability are high in geriatric patients treated with a rigid cervical collar. Fracture healing and stability did not correlate with improved outcomes. Outcomes did not differ significantly from age-matched cohorts.

Fractures: Bone Repair
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...

Oxygen Delivering System II: Venturi Mask and Transtracheal Oxygen
Venturi Mask
The Venturi mask, named after the Venturi effect, is designed to deliver precise oxygen concentrations. It consists of a large tube with an oxygen inlet that narrows down, causing a pressure drop that pulls air in through adjustable side ports. The mask is a lightweight,...
