An evaluation of three-dimensional image-guided technologies in percutaneous pelvic and acetabular lag screw placement.

Background: Percutaneous stabilization using three-dimensional (3D) navigation system is a promising treatment for pelvic and acetabular fractures. However, there are still some controversies regarding the use of 3D navigation to treat pelvic and acetabular fractures. The purpose of this study was to compare the Iso-C(3D) fluoroscopic navigation, standard fluoroscopy, and two-dimensional (2D) fluoroscopic navigation in placing percutaneous lag screws in pelvic specimens to better understand the merits of 3D navigation techniques.

[Operative treatment of the scapular fractures through modified Judet approach].

Objective: To investigate the effect of operative treatment of scapular fractures through modified Judet approach.

Methods: From January 1997 to October 2005, 21 patients (15 females, 6 males; mean age 34 years) of scapular fractures were treated by open reduction and internal fixation through the modified Judet approach. According to Hardegger classification system, there were 11 patients of scapular body fractures, 10 patients of scapular neck fractures, 8 patients of glenoid rim fractures, 7 patients of glenoid fossa fractures, 9 patients of scapular spine fractures, and 6 patients of scapular acromion fractures.

The diagnosis and treatment of severe cerebral fat embolism.

Objective: To improve the diagnosis and treatment of severe cerebral fat embolism (SCFE).

Methods: The data of nine patients with SCFE were retrospectively analyzed. The manifestations of the central nerve system, respiratory system and hemorrhage were recorded, at the same time, accessory examination including arterial oxygen, fat macroglobules in venous blood and image examination was adapted.
