The inferior sacral iliac line as a horizontal reference plane in paediatric pelvic radiographs.

Background: While often used, Hilgenreiner's line may not always be a reliable reference plane following triple innominate pelvic osteotomy or trauma to the triradiate cartilage. The inferior sacral-iliac line is a horizontal line connecting the sclerotic corners of the inferior sacral-iliac joints. This is a consistent landmark in the ossifying infant pelvis as well as the fully developed adult pelvis.

Mental Skills for Orthopaedic Surgery.

Orthopaedic surgery training focuses primarily on the knowledge base and surgical techniques that comprise the fundamental and physical pillars of performance. It also pays much less attention to the mental pillar of performance than does the training of other specialists such as aviators, elite athletes, musicians, and Special Forces operators. However, mental skills optimize the ability to achieve the ideal state during surgery that includes absolute focus with the right amount of confidence and stress.

Femoral Fixation Strength as a Function of Bone Plug Length in Anterior Cruciate Ligament Reconstruction Utilizing Interference Screws.

Purpose:  To determine femoral construct fixation strength as bone plug length decreases in anterior cruciate ligament reconstruction (ACLR).

Methods:  Sixty fresh-frozen bone-patellar tendon-bone allografts were utilized and divided into 20-, 15-, and 10-mm length bone plug groups, subdivided further so that half utilized the patella side (P) for testing and half used the tibial side (T). Ten mm diameter recipient tunnels were created within the anatomic anterior cruciate ligament footprint of 60 cadaveric femurs.

Double-Row Capsulolabral Repair Increases Load to Failure and Decreases Excessive Motion.

Purpose: Using a cadaver shoulder instability model and load-testing device, we compared biomechanical characteristics of double-row and single-row capsulolabral repairs. We hypothesized a greater reduction in glenohumeral motion and translation and a higher load to failure in a mattress double-row capsulolabral repair than in a single-row repair.

Methods: In 6 matched pairs of cadaveric shoulders, a capsulolabral injury was created.

Targeted Muscle Reinnervation of the Brachium: An Anatomic Study of Musculocutaneous and Radial Nerve Motor Points Relative to Proximal Landmarks.

Purpose: Targeted muscle reinnervation (TMR) offers enhanced prosthetic use by harnessing additional neural control from unused nerves in the amputated limb. The purpose of this study was to document the location and number of motor end plates to each muscle commonly used in TMR in the brachium relative to proximally based bony landmarks.

Methods: We dissected 18 matched upper limbs (9 fresh-frozen cadavers).
