Today we talk about the most recent studies and technologies of orthopedics.

Do you know what was going on this week in the orthopedic field in the world? Today we talk about the most recent studies and technologies of this area.

Kidney Stones and their Relation to the Bone Fracture Risk

The Journal of Bone and Mineral Research findings show that patients with kidney stones are deliberately ready to have osteoporosis or bone fracture disease. They believe that one-quarter of adults with kidney stones were diagnosed to have a bone fracture.

Calyani Ganesan, MD, MS, a clinical scholar and postdoctoral research fellow in the division of nephrology at Stanford University, told Healio believes that doctors underappreciate the risk of bone fracture in patients with kidney stones.

"There is a high prevalence of the bone disease among patients with kidney stones, yet only a small proportion of patients with kidney stones receive bone density screening," Ganesan said, "The risk of bone disease in patients with kidney stones is currently underappreciated. Clinicians should consider bone density screening in patients with kidney stones to detect osteoporosis and initiate treatment to prevent fractures."

She demonstrates that the results support the risk of osteoporosis or fractures in middle-aged and older men with kidney stone disease.

"Future work identifying which patients with kidney stones are at highest risk for fracture and the effects of anti-osteoporosis medications on kidney stone recurrence are necessary," Ganesan said. 

The Difference between Patients Treated with Hip Plating VS Sliding Hip Screws

In a study with 1128 patients with trochanteric hip, scientists discovered the same result for patients treated with hip plating or sliding hip screws.

The researchers run the experiment for 437 patients with hip plating systems and 443 patients with sliding hip screws. In the end, they have not seen any difference between these two groups. Also, they have not seen any difference in the outcomes between the two groups.

"This was a large trial in a frail patient group, whose main desire is to stay out of the hospital and to maintain their independence," Brian Thornes, MD, MS, FRCSI, C.E.O. of X-Bolt Orthopedics, said in a company press release. "The data confirms the outstanding safety profile of the X-Bolt, which virtually eliminates 'cut out' as an issue. I am also delighted that the clinical impact translates into intangibly better outcomes for a significant number of patients."

The Newest F.D.A. Approval for 3D-Printed Talus Implant

The first kind of implant to replace the talus gets its U.S Food and Drug Administration Approval. This Talus Spacer 3D printed talus replaces the bone in the ankle joint connecting the leg and the foot.

Now patients with avascular necrosis can benefit from this and prevent the death of bone tissue.

Raquel Peat, Ph.D., M.P.H., USPHS, Director of the F.D.A.'s Center for Devices and Radiological Health's Office of Orthopedic Devices says: "Avascular necrosis of the ankle, while a rare condition, is a serious and potentially debilitating one that causes pain and can lead to inhibited motion of the ankle joint, and in some cases, removal of part of the leg. Today's action provides patients with a treatment option that could potentially reduce pain, retain range of motion of their joint and improve quality of life."

Each patient should have his talus spacer. This spacer is a 3D-printed implant that is modeled based on computed tomography imaging and fits the patient's specific anatomy.

During the surgery, the doctor replaces the talus implant with the patient's talus bone. The implant is made of cobalt-chromium alloy.

The surgeries' results support the effectiveness of this implant after 3 years in 32 patients who have done the talus replacement.

A Safer Bone Tumor Treatment with Radioactive Bone Cement

According to a study led by the University of California, Irvine, researchers have found that in patients with bone tumors, radioactive bone cement injected into the bone is a safer alternative to conventional radiation therapy.

The benefit of placing brachytherapy cement is that the surgeon places it directly into the bone and irradiates the tumor without harming the spinal cord.

Joyce Keyak, Lead Researcher, Professor of Radiological Sciences, University of California, Irvine, says: "Brachytherapy cement could be used without delay in a convenient, one-step, minimally invasive treatment to irradiate tumors, and would not irradiate the spinal cord or limit future treatment options."

Patients with various cancers such as breast, prostate, lung, thyroid, or kidney are more susceptible to have the cancer spreader in their body and threaten the bones and spine. Various methods are used to treat cancer that has spread to the spine, but they have many unpleasant side effects.

Patients with bone cancer are forced to pass 10 or more radiation therapy sessions, but with this method, they need just one injection to have the equivalent effect.

They ran an animal study which shows the effectiveness of this method.

"This localized treatment for bone tumors stays localized, and we did not see any effects outside the bone," Keyak said. "This is important because traditional radiation therapy causes adverse effects such as nausea, vomiting, and diarrhea."

They have represented their experiment in the Orthopedic Research Society's annual meeting on February 12-16.

"You can have this procedure and be done with it," she said. "And you can do it when tumors are smaller to prevent further bone and spinal cord damage while limiting the pain and side effects that patients often feel."

After completing the animal studies, they will begin the application for the clinical trial.
