Is There a Correlation between the Radiological and Clinical Outcome after Core Decompression of the Radius for Kienböck Disease?

Despite the good clinical results in the treatment of Kienböck disease with distal radius core decompression, a radiological progression to a certain degree in the long-term follow-up is possible. Is there a negative correlation between the clinical improvement of the patients and the radiological progression? We retrospectively reviewed the radiological and clinical results of 24 patients (mean age: 38 years; 10 women) treated with core decompression for Kienböck disease. The mean follow-up was 10 years.

The modified Lapidus fusion: a systematic review of biomechanical studies.

Purpose: The biomechanical characteristics of different techniques to perform the modified Lapidus procedure are controversial, discussing the issue of stability, rigidity, and compression forces from a biomechanical point of view. The aim of this systematic review was to investigate the available options to identify whether there is a procedure providing superior biomechanical results.

Methods: A comprehensive literature search was performed by screening PubMed, Embase, and Cochrane databases until September 2021.

Hinge plate technique for osteosynthesis of comminuted proximal humeral fractures.

Background: Several surgical techniques of osteosynthesis have been described for treatment of proximal humeral fractures. There is evidence that the quality of reduction improves the clinical outcome and decreases the number of complications. Reduction of the medial calcar is tricky when standard manoeuvres are performed.

Use of Intraoperative CT Improves Accuracy of Spinal Navigation During Screw Fixation in Cervico-thoracic Region.

Study Design: A retrospective analysis of a single-center consecutive series of patients.

Objective: To test the hypothesis that using a mobile intraoperative computed tomography in combination with spinal navigation would result in better accuracy of lateral mass and pedicle screws between C3 and T5 levels, compared to cone-beam computed tomography and traditional 2D fluoroscopy.

Summary Of Background Data: Use of spinal navigation associated with 3D imaging has been shown to improve accuracy of screw positioning in the cervico-thoracic region.

Posterior pelvic ring fractures: Intraoperative 3D-CT guided navigation for accurate positioning of sacro-iliac screws.

Introduction: Posterior pelvic ring fractures frequently pose a problem of stability with an elevated risk of complications. The traditional method of percutaneous sacroiliac (SI) stabilization with the use of fluoroscopic image amplifiers demands a high degree of experience and has an elevated risk of screws' malpositioning.

Hypothesis: Intraoperative 3D-CT scan coupled with a navigation system (O-Arm) can allow screw fixation accuracy while limiting the risk of complications for the treatment of posterior pelvic ring fractures.
