3D Printing Technology in Planning Thumb Reconstructions with Second Toe Transplant
ConclusionsWhen planning a wrap‐around flap and second toe transplant to reconstruct a thumb, both the donor and recipient sites can be modeled using 3D printing. This can shorten the operative time by supplying digital and accurate schematics for the operation. It can also optimize the function and appearance of the reconstructed thumb while minimizing damage to the donor site. (Source: Orthopaedic Surgery)

Computer ‐assisted Orthopaedic Surgery
Nowadays, operating rooms can be inefficient and overcrowded. Patient data and images are at times not well integrated and displayed in a timely fashion. This lack of coordination may cause further reductions in efficiency, jeopardize patient safety, and increase costs. Fortunately, technology has much to offer the surgical disciplines and the ongoing and recent operating room innovations have advanced preoperative planning and surgical procedures by providing visual, navigational, and mechanical computerized assistance. The field of computer‐assisted surgery (CAS) broadly refers to surgical interface between surgeons an...

A Radiographic Measurement of the Anterior Epidural Space at L4 –5 Disc Level
To observe the morphology character of the anterior epidural space at the L4–5 disc level and to provide an anatomical basis for safely and accurately performing a percutaneous endoscopic lumbar discectomy (PELD). Fifty‐five cases with L5S1 lumbar disc herniation were included in this study, and cases with L4–5 disease were excluded. When the puncture needle reached the epidural space at the L5S1 level, iohexol was injected at the pressure of 50 cm H2O during the PELD, then C‐Arm fluoroscopy was used to obtain standard lumbar frontal and lateral images. The widths of epidural space at the level of the L4 lower en...

Pull out Strength of Dual Outer Diameter Pedicle Screws Compared to Uncemented and Cemented Standard Pedicle Screws: A Biomechanical in vitro Study
ConclusionsFor clinical application, cement augmentation remains the gold standard for increasing screw stability. According to our results, the use of a dual outer diameter screw is an interesting option to increase screw stability in the lumbar region without cement augmentation. For the thoracic region, however, the screw‐to‐pedicle diameter should be checked and attention should be paid to screw cut out, if the dual outer diameter screw is considered.

Internal Fixation of Complicated Acetabular Fractures Directed by Preoperative Surgery with 3D Printing Models
The purpose of this article is to evaluate the efficacy and feasibility of preoperative surgery with 3D printing‐assisted internal fixation of complicated acetabular fractures. A retrospective case review was performed for the above surgical procedure. A 23‐year‐old man was confirmed by radiological examination to have fractures of multiple ribs, with hemopneumothorax and communicated fractures of the left acetabulum. According to the Letounel and Judet classification, T‐shaped fracture involving posterior wall was diagnosed. A 3D printing pelvic model was established using CT digital imaging and communications in ...

Giant Cell Tumor of the Mobile Spine Occurring in Pregnancy: A Case Report and Literature Review
This report adds to the existing literature, making the reader aware that clinical symptoms of GCT in the mobile spine can be misinterpreted as a symptom of pregnancy. For spinal GCT in pregnant women, continued pregnancy and definitive surgery after the baby is born are recommended without any serious nerve damage. (Source: Orthopaedic Surgery)

Posterior Lumbar Interbody Fusion with Interspinous Fastener Provides Comparable Clinical Outcome and Fusion Rate to Pedicle Screws
ConclusionThe less invasive ISF combined with PLIF provided comparable clinical outcome and a similar bone fusion rate to pedicle screws. The ISF could potentially serve as a new alternative for lumbar degenerative diseases. (Source: Orthopaedic Surgery)

Rod Migration to the Thoracic Subarachnoid Space after C1 –2 Instrumentation: A Case Report and Literature Review
In this study, we report a case of atlantoaxial stabilization using the screw‐rod technique that was followed by rod migration to the thoracic subarachnoid space, and outline the subsequent management of the case. Failure of bony fusion can result in micromotion and subsequent migration of fixation device components. Routine radiographic follow‐up could be used to identify migration events.

Effect of Femoral Component Flexion Implantation on the Mediolateral Bone ‐prosthetic Fit in Total Knee Arthroplasty
ConclusionThe present study demonstrated that femoral component flexion implantation by 3° can reduce excessive overhang, although 3.10 mm of overhang remained at the medial side of zone 1. Conversely, 6° of flexion implantation can avoid 3 mm of overhang for any zone, but increases the risk of underhang. Slight flexion implantation may be an effective alternative technique to prevent excessive component overhang, especially in the trochlea and anterior region of the distal condyle, in Chinese patients with standard TKA prostheses.
