Case ReportsIntervertebral Fusion with Mobile Microendoscopic Discectomy for Lumbar Degenerative Disc Disease.
The aim of this article is to introduce a technique for lumbar intervertebral fusion that incorporates mobile microendoscopic discectomy (MMED) for lumbar degenerative disc disease. Minimally invasive transforaminal lumbar interbody fusion is frequently performed to treat degenerative diseases of the lumbar spine; however, the scope of such surgery and vision is limited by what the naked eye can see through the expanding channel system. To expand the visual scope and reduce trauma, we perform lumbar intervertebral fusion with the aid of a MMED system that provides a wide field through freely tilting the surgical instrument and canals. We believe that this technique is a good option for treating lumbar degenerative disc disease that requires lumbar intervertebral fusion.

Randomized Controlled Trial Comparative StudyMini-invasive Transforaminal Lumbar Interbody Fusion through Wiltse Approach to Treating Lumbar Spondylolytic Spondylolisthesis.
To assess the clinical efficacy of mini-invasive transforaminal lumbar interbody fusion (TLIF) through the Wiltse approach for treating lumbar spondylolytic spondylolisthesis. ⋯ TLIF via both approaches has satisfactory clinical efficacy. TLIF through the Wiltse approach significantly reduces the damage of multifidus and postoperative incidence of chronic LBP.

Effect of Interbody Fusion on the Remaining Discs of the Lumbar Spine in Subjects with Disc Degeneration.
To study effects (stress loads) of lumbar fusion on the remaining segments (adjacent or not) of the lumbar spine in the setting of degenerated adjacent discs. ⋯ Stresses are greater in flexion at the endplates of L3-4 and in flexion and extension at L2-3 in the presence of L3-4 disc disease and L4-5 fusion than in the control group. In all other combinations of fusion and disc disease, endplate stress was less for all levels tested than in the control model.

Case ReportsEfficiency and Accuracy of Bernese Periacetabular Osteotomy for Adult Hip Dysplasia.
Bernese periacetabular osteotomy (PAO) has several advantages dealing with adolescents and adults acetabular dysplasia. The authors introduced the details and steps performing PAO, with attached video and schematic diagram which demonstrates a perfect PAO in efficiency and accuracy. The patient is an 18-year-old girl, complaining hip pain on the left side for 6 months. ⋯ The patient is very happy to the surgery with no hip pain, with normal gait, ROM, and Harris hip scores (HHS). In summary, PAO is a relative new and efficient procedure for adult hip dysplasia, requiring accurate techniques. Cadaveric practice and familiar with the local anatomy can help the surgeon overcome the learning curve quickly.

ReviewPeriprosthetic Distal Femur Fracture after Total Knee Arthroplasty: A Systematic Review.
This study was designed to itemize and analyze the classification of fracture types and their corresponding outcomes in an attempt to provide a better understanding of the current treatment methods. Two PubMed searches were performed using the words "periprosthetic distal femur fracture" and "periprosthetic supracondylar femur fracture" in studies that were published in the previous 10 years (2004-2014). Data from 41 articlesthat met the general inclusion criteria, were collected and categorized into fracture type and treatment method groupings. ⋯ In conclusion, the most frequent type of periprosthetic distal femur fracture after total knee arthroplasty was Rorabeck type II. The most common treatments for these types of fractures are locked plating and intramedullary nailing, with similar healing rates of 87% and 84%, respectively. However, the complication rate for locked plating was lower than for intramedullary nailing.
