The Potency of Platelet-Rich Plasma for Chronic Low Back Pain: A Systematic Review and Metaanalysis of Randomized Controlled Trial.

May 15, 2023

Low back pain is one of the leading causes of disability in the world. Regenerative medicine can be one of the novel treatment breakthroughs in patients with low back pain, yet its use is still debata...

New Insights into Calorie Restriction Induced Bone Loss.

May 08, 2023

Caloric restriction (CR) is now a popular lifestyle choice due to its ability in experimental animals to improve lifespan, reduce body weight, and lessen oxidative stress. However, more and more emerg...

Concomitant valgus hip osteotomy in operative fixation of displaced proximal femoral neck fractures.

May 08, 2023

Total hip arthroplasty (THA) is considered the preferred treatment for displaced proximal femoral neck fractures. However, in many countries this option is economically unviable. To improve outcomes i...

Orbital wall restoration with primary bone fragments in complex orbital fractures.

May 08, 2023

Complex orbital fractures are impure orbital fractures because they involve the orbital walls and mid-facial bones. The author reported an orbital wall restoration technique in which the primary orbit...

Long-term outcomes after core extirpation of fibrous dysplasia of the zygomaticomaxillary region.

May 08, 2023

Fibrous dysplasia (FD) is a localized bone disorder in which fibro-osseous tissue replaces the normal bone structure. Patients with craniofacial FD often present with gradual swelling, deformity, and ...

Effect of low-intensity pulsed ultrasound on osteogenic differentiation of human induced membrane-derived cells in Masquelet technique.

Apr 17, 2023

The Masquelet technique is a relatively new method for large bone defect treatment. In this technique, grafted bone tissue is used, and after the cement is removed, the induced membrane (IM; that form...

3D-printing a cost-effective model for mastoidectomy training.

Apr 17, 2023

3D-printed temporal bone models can potentially provide a cost-effective alternative to cadaver surgery that can be manufactured locally at the training department. The objective of this study was to ...

Classification of unusual fracture patterns of the mandible: A retrospective study.

Apr 10, 2023

The aim of this study is to devise and summarize a classification of fracture patterns involving multiple anatomical sites of the mandible. A retrospective study was conducted by reviewing clinical ca...

Therapeutic strategy for atypical ulnar fracture in long use of bisphosphonate: A systematic review.

Apr 10, 2023

Atypical fractures are caused by the combined effects of severe suppression of bone metabolism (SSBT) due to long-term bisphosphonate therapy and chronic repetitive bone microdamage. Atypical ulnar fr...

Immunohistochemical characterization of the mandibular condyle for type I and II collagen, aggrecan, MMP-9, and MMP-13 in MMP-2-deficient mice.

Apr 03, 2023

Mice devoid of matrix metalloproteinase (MMP)-2 due to gene targeting have been reported to show articular cartilage destruction in the knee joint; however, the phenotype of the mandibular condylar ca...

Photon-counting CT of elbow joint fractures: image quality in a simulated post-trauma setting with off-center positioning.

Mar 27, 2023

Photon-counting detector computed tomography (PCD-CT) has the potential to provide superior image quality compared to energy-integrating detector computed tomography (EID-CT). We compared the two syst...

Closed reduction of dorsally displaced distal radius fractures in the elderly provided improved final radiographic results.

Mar 27, 2023

Recent guidelines recommend non-operative treatment as primary treatment in elderly patients with displaced distal radius fractures. Most of these fractures are closely reduced. We aimed to evaluate t...

Is proximal tibial tubercle osteotomy superior to distal tibial tubercle osteotomy for medial compartmental osteoarthritis? A meta-analysis.

Mar 27, 2023

Open-wedge high tibial osteotomy (OWHTO) is commonly performed for the treatment of medial compartment knee osteoarthritis (KOA), and is classified into proximal tibial tubercle osteotomy (PTO) and di...

Widespread proprioceptive acuity impairment in chronic back pain: a cross-sectional study.

Mar 20, 2023

To investigate whether proprioceptive accuracy measured with the Joint Position Sense (JPS) in patients with chronic neck and low back pain is impaired exclusively in affected areas or also in distant...

Case series of medication-related osteonecrosis of the jaw (MRONJ) patients prescribed a drug holiday.

Mar 20, 2023

The role of a drug holiday in the management of medication-related osteonecrosis of the jaw (MRONJ) remains controversial. Current UK guidance does not recommend this practice given the lack of conclu...

Nucleated red blood cell: a feasible quality parameter of cord blood units.

Mar 20, 2023

Umbilical cord blood is an alternative source of hematopoietic progenitor cells for bone marrow transplantation; however, it is associated with a higher graft failure rate. The presence of a high rate...

Which is the Best Solution for Achieving Maximal Interfragmentary Compression of the Scaphoid Fractures - One or Two Herbert Screws?

Mar 13, 2023

PURPOSE OF THE STUDY To compare the treatment outcome of scaphoid facture fixation with one versus two Herbert screws (HBS). MATERIAL AND METHODS 72 patients underwent open reduction internal fixation...

5th Metatarsal Jones Fracture - To Treat Conservatively, or Surgically Using Headless Double-Threaded Herbert Screw?

Mar 13, 2023

PURPOSE OF THE STUDY Fifth metatarsal fractures, in particular so-called Jones fractures, are relatively common injuries both in the general population and athletes. Although discussions about whether...

Magnetic resonance imaging of organ iron before and after correction of iron deficiency in patients with heart failure.

Mar 13, 2023

Intravenous iron therapy (IVIT) is known to improve functional status in chronic heart failure (CHF) patients. The exact mechanism is not completely understood. We correlated magnetic resonance imagin...
