Trans-iliac removal of bullet fragments from the sacroiliac joint.

The need for removal of intra-articular bullet fragments is well documented in the literature. Arthroscopy and arthrotomy are the preferred methods to access large superficial joints; however, these methods cannot be effectively used to access the sacroiliac joint. Its relationship to vital soft tissues and its convoluted joint anatomy make it almost impossible to explore even under open methods. We propose a new percutaneous technique for the removal of intra-articular bullet fragments from the sacroiliac joint. Our method meets two important goals: 1) percutaneous minimally invasive approach to the joint, and 2) removal of the bullet fragments while avoiding the potential morbidity of an open procedure.

Does retrieval fluency contribute to the underconfidence-with-practice effect?

Judgments of learning (JOLs) made during multiple study-test trials underestimate increases in recall performance across those trials, an effect that has been dubbed the underconfidence-with-practice (UWP) effect. In 3 experiments, the authors examined the contribution of retrieval fluency to the UWP effect for immediate and delayed JOLs. The UWP effect was demonstrated with reliable underconfidence on Trial 2 occurring for both kinds of JOL. However, in contrast to a retrieval-fluency hypothesis, fine-grained analyses indicated that the reliance of JOLs on retrieval fluency contributed minimally to the UWP effect. Our discussion focuses on the status of the retrieval-fluency hypothesis for the UWP effect.
