The glenoid track uses both glenoid and humeral head bone loss to predict subsequent risk of humeral head engagement and possible dislocation. The glenoid track shows us that restoring the track to its natural width should be among the surgeon's first priority in restoring shoulder stability. Humeral head lesions, also known as Hill-Sachs lesions, are surgically addressed when they cause clinical symptoms. Symptoms arise when the medial margin of the defect engages the glenoid track.

BR 3D reconstructions accurately and reliably provide clinical data on femoral version compared to CT even with rotation of the patient of up to 10° from neutral.

A previously healthy 30-year-old woman presented with 3 years of progressive shortness of breath and audible wheezing. One year prior to presentation, she developed a chronic non-productive cough. Pulmonary function testing revealed flattened inspiratory and expiratory peaks, characteristic of an extrathoracic fixed tracheal obstruction. Bronchoscopy confirmed subglottic stenosis (SGS). She had no history of intubation, tracheostomy or evidence of a systemic inflammatory illness. She was diagnosed with idiopathic SGS and referred for rigid bronchoscopy with balloon dilatation resulting in improvement in her symptoms.
