"Simultaneous regeneration of full-thickness cartilage and subchondral bone defects in vivo using a three-dimensional scaffold-free autologous construct derived from high-density bone marrow-derived mesenchymal stem cells."

"In recent years, several methods have been developed for repairing full-thickness cartilage defects by tissue engineering using mesenchymal stem cells. Most of these use scaffolds to achieve sufficient thickness. However, considering the potential influence of scaffolds on the surrounding microenvironment, as well as immunological issues, it is desirable to develop a scaffold-free technique. In this study, we developed a novel technique, a scaffold-free autologous construct derived from bone marrow-derived mesenchymal stem cells (BM-MSCs), and successfully use this technique to regenerate cartilage and subchondral bone to repair an osteochondral defect in rabbit knees."

The importance of this article is that with this regeneration of the cartilage, patients would be able to improve significally after having surgery, there will be no more waits or bad news.
Which should be our priority now are prices and accessibility for people with a low socio-economical lifestyle.

"Discriminating imaging findings of acute osteoporotic vertebral fracture: a prospective multicenter cohorte study."

Appropriate treatment of osteoporotic vertebral fractures (OVF) requires knowledge of the age of the fracture. Although diagnostic imaging has made remarkable progress in recent years, it remains difficult to differentiate acute fractures from old. 

Its is important to know the age of the fracture since its tratment is completely unique dependen on the age. 
In this article we are taught how to discriminate the aging so we can give out patients the right treatment and not get confuse because it would be a problem for the patients fracture or bones.

Lifetime of fitness: A fountain of youth for bone and joint health?

"Being physically active may significantly improve musculoskeletal and overall health, and minimize or delay the effects of aging according to a review of the latest research on senior athletes (ages 65 and up) appearing in the September issue of the Journal of the American Academy of Orthopaedic Surgeons (JAAOS)."
 
It long has been assumed that aging causes an inevitable deterioration of the body and its ability to function but recent research on senior, elite athletes suggests usage of comprehensive fitness and nutrition routines helps minimize bone and joint health decline and maintain overall physical health.
 
“An increasing amount of evidence demonstrates that we can modulate age-related decline in the musculoskeletal system,” said lead study author and orthopaedic surgeon Bryan G. Vopat, MD. “A lot of the deterioration we see with aging can be attributed to a more sedentary lifestyle instead of aging itself.”
 
The positive effects of physical activity are the bone density, muscle mass, ligament and tendon function, and cartilage volume are keys to optimal physical function and health. 

Como of the recomedations are:

1. Resistance training.

2. Endurance training. 

3. Flexibility and balance. 

Not only doing exercise but having a healthy diet to optimize performance.

The ortho-plastic management of Gustilo grade IIIB fractures of the tibia in children: A systematic review of the literature.

"The challenges of managing Gustilo IIIB tibial fractures in children are unique. A multi-disciplinary, evidence based approach is needed. We aimed to evaluate the evidence for the ortho-plastic management of Gustilo grade IIIB open tibial shaft fractures in children based on a review of all published data in order to rationalise the orthopaedic and plastic surgical approach to these complex injuries." 

This article talks about how children are the very first affected people speaking about fractures, especially the tibial ones since it is common to have accidents while playing.

As the fracture is in children, their bones are not totally developed and its pretty easier to recoger fastly from surgery. But, we should not be that confident, like other patients, the child must be our priority.

Drug study shows improvement in major orthopedic surgery care

Through ages, drugs have been acting as a powerful tool to help doctors and patients to handle pain this is why its not surprising that the drug study showed and improvement in major orthopedic surgery care,since it is of course, use with medical porposes.

As a drug, we MUST use it ONLY IF NECESSARY. Like other kind of drugs, it is addictive and can cause secuels.
We are aware of the big importance drugs have in surgiereis and soon there will be no doubt it has different ways of its use and results.

The learning curve for minimally invasive Oxford phase 3 unicompartmental knee arthroplasty: cumulative summation test for learning curve (LC-CUSUM)

In this article, we can appreciate that the minimally invasive Oxford unicompartmental knee arthroplasty is a demanding procedure but has many advantages compared with total knee arthroplasty. "The aim of this observational study was to investigate the learning curve of one experienced surgeon introducing minimally invasive Oxford phase 3 UKA into his routine clinical practice."
Talking about surgery, it is necessary to improve different ways of approaching the problem in order to achieve a better quality of surgery, surgeons and patients.

An interactive surgical planning tool for acetabular fractures: initial results

Background

Acetabular fractures still are among the most challenging fractures to treat because of complex anatomy, involved surgical access to fracture sites and the relatively low incidence of these lesions. Proper evaluation and surgical planning is necessary to achieve anatomic reduction of the articular surface and stable fixation of the pelvic ring. The goal of this study was to test the feasibility of preoperative surgical planning in acetabular fractures using a new prototype planning tool based on an interactive virtual reality-style environment.

Methods

7 patients (5 male and 2 female; median age 53 y (25 to 92 y)) with an acetabular fracture were prospectively included. Exclusion criterions were simple wall fractures, cases with anticipated surgical dislocation of the femoral head for joint debridement and accurate fracture reduction. According to the Letournel classification 4 cases had two column fractures, 2 cases had anterior column fractures and 1 case had a T-shaped fracture including a posterior wall fracture.

The workflow included following steps: (1) Formation of a patient-specific bone model from preoperative computed tomography scans, (2) interactive virtual fracture reduction with visuo-haptic feedback, (3) virtual fracture fixation using common osteosynthesis implants and (4) measurement of implant position relative to landmarks. The surgeon manually contoured osteosynthesis plates preoperatively according to the virtually defined deformation. Screenshots including all measurements for the OR were available.

The tool was validated comparing the preoperative planning and postoperative results by 3D-superimposition.

Results

Preoperative planning was feasible in all cases. In 6 of 7 cases superimposition of preoperative planning and postoperative follow-up CT showed a good to excellent correlation. In one case part of the procedure had to be changed due to impossibility of fracture reduction from an ilioinguinal approach. In 3 cases with osteopenic bone patient-specific prebent fixation plates were helpful in guiding fracture reduction. Additionally, anatomical landmark based measurements were helpful for intraoperative navigation.

Conclusion

The presented prototype planning tool for pelvic surgery was successfully integrated in a clinical workflow to improve patient-specific preoperative planning, giving visual and haptic information about the injury and allowing a patient-specific adaptation of osteosynthesis implants to the virtually reduced pelvis.
