Biomechanical comparison of headless compression screws versus independent locking screw for intra-articular fractures.

Purpose: Headless compression screws (HCS) have a variable thread pitch and headless design enabling them to embed below the articular surface and generate compression force for fracture healing without restricting movement. Locking screws have greater variety of dimensions and a threaded pitch mirroring the design of the HCS. The objective of this study is to determine whether locking screws can generate compression force and compare the compressive forces generated by HCS versus locking screws.

Cut and cure: surgical therapy of synovitis.

Surgical management for synovitis has undergone radical change in the last few years with the evolution of DMARDs and advanced Interventional Radiology techniques. Here we present areas where surgical therapy may still be the most effective option, either alone or in conjunction with non-surgical measures.

Trapeziectomy versus joint replacement for first carpometacarpal (CMC 1) joint osteoarthritis: a systematic review and meta-analysis.

Purpose: This systematic review and meta-analysis directly compares joint replacement (JR) and trapeziectomy techniques to provide an update as to which surgical intervention is superior for first carpometacarpal (CMC-1) joint osteoarthritis.

Methods: In August 2020, MEDLINE, Embase and Web of Science were searched for eligible studies that compared these two techniques for the treatment of CMC-1 joint osteoarthritis (PROSPERO registration ID: CRD42020189728). Primary outcomes included the Disabilities of the Arm, Shoulder and Hand (DASH), QuickDASH (QDASH) and pain visual analogue scale (VAS) scores.

Adjustable Loop Femoral Cortical Suspension Devices for Anterior Cruciate Ligament Reconstruction: A Systematic Review.

Background: Anterior cruciate ligament (ACL) injury is a common sports injury. Symptomatic knee instability after this injury is usually treated operatively through ACL reconstruction. The surgery involves a tendon graft being fixed in bony tunnels drilled through femur and tibia.

Glucosamine reduces the inhibition of proteoglycan metabolism caused by local anaesthetic solution in human articular cartilage: an in vitro study.

Background: We assessed whether local anaesthetics caused inhibition of proteoglycan metabolism in human articular cartilage and whether the addition of Glucosamine sulphate could prevent or allow recovery from this adverse effect on articular cartilage metabolism.

Methods: Cartilage explants obtained from 13 femoral heads from fracture neck of femur patients (average age 80 years, 10 female) were exposed to either 1% Lidocaine, 2% Lidocaine, 0.25% Bupivacaine, 0.

Advances in 3D Modeling: Preoperative Templating for Revision Wrist Surgery.

Background: Three-dimensional (3D) printing is a computer-directed process leading to the layered synthesis of scaled models. The popularity and availability of the technique has exponentially increased over the last decade, and as such is seeing a greater number of medical and surgical applications.

Methods: We report 3 cases involving the use of 3D printing as an aid to operative planning in the revision of wrist surgery.

The Role of 3D Modelling and Printing in Orthopaedic Tissue Engineering: A Review of the Current Literature.

Orthopaedic surgery lends itself well to advances in technology. An area of interest and ongoing research is that of the production of scaffolds for use in trauma and elective surgery. 3D printing provides unprecedented accuracy in terms of micro- and macro-structure and geometry for scaffold production.

Three-dimensional printing in surgery: a review of current surgical applications.

Background: Three-dimensional printing (3DP) is gaining increasing recognition as a technique that will transform the landscape of surgical practice. It allows for the rapid conversion of anatomic images into physical objects, which are being used across a variety of surgical specialties. It has been unclear which groups are leading the way in coming up with novel ways of using the technology and what specifically the technology is being used for.

Successful laparoscopic removal of an ingested toothbrush.

Most ingested foreign bodies will pass through the gastrointestinal tract without any problems. On the other hand long, slender objects such as a toothbrush will rarely be able to negotiate the angulated and fixed retroperitoneal duodenal loop. Spontaneous toothbrush passage has never been described and therefore endoscopic or surgical removal is always required.
