Background: Currently, antibodies are progressively applied in medicine for different purposes, including diagnostic and therapeutic indications. Over twenty monoclonal antibodies utilized for many therapeutic reasons from therapy of cancers, immune disorders, and osteoporosis to localized bony defects. In addition, therapeutic antibodies represented various findings in bone tissue engineering.
Objectives: The current study aims to systematically review the available literature on antibody assisted bone regeneration in animal models.
Methods: A through electronic search was conducted from January 1992 to June 2017 limited to English language publications on administrations of antibodies for bone regeneration. Data extraction was ere performed according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement.
Results: Twenty studies were selected and analyzed in this systematic review. Among these studies, six articles reported in vitro results in addition to in vivo evaluations. The data is tabulated according to the route of administrations as locally administrated antibody which includes anti-bone morphogenetic protein 2 (anti-BMP2) and systemic administrated antibodies, which include anti-sclerostin and anti- Dickkopf-1 (DKK1). Data are summarized and reported by the following variables: Type of study, types of cells for in vitro investigations, types of animal models and defects characteristics, types of scaffolds used in the defect site, duration of follow-ups; and outcomes of assessments.
Conclusions: A novel approach of administration of antibodies demonstrated promising results for bone tissue engineering. However, more investigations, particularly in larger animals, are required for their further possible clinical administration.

A biologically safe, noninvasive method for visualizing bone and soft tissue relationships has been developed recently. Termed the ultrasonic transmission imaging system, its advantages include visualization of soft tissues in real time while motion is underway. The image can be correlated to standard x-ray films, but since no ionizing radiation is involved, repeated risk-free visualization of extremities for either diagnostic assessment or biomechanical studies is permitted.

Patellar instability following total knee arthroplasty (TKA) is a rare, yet serious complication, potentially requiring revision surgery or resulting in chronic dysfunction. When encountered, it is paramount to understand the etiologies, diagnostic approaches, treatment options, and outcomes of the selected treatment. The most common cause of patella instability is improper positioning of components, leading to lateral maltracking of the patella.

In developing nations, patients often rely on traditional bone setters, leading to delayed diagnosis and increased complications. Adult hip dislocations carry a higher risk of avascular necrosis and require complex treatments.

Aims: Neuron death is caused primarily by apoptosis after spinal cord injury (SCI). Autophagy, as a cellular response, can maintain cellular homeostasis to reduce apoptosis. We aimed to investigate the effect and the mechanism of vimentin knockdown on autophagy and neural recovery after SCI.

In cases of large mandibular continuity defects resulting from malignancy resection, the current standard of care involves using patient-specific/custom titanium reconstruction plates along with autogenous grafts (fibula, scapula, or iliac crest segments). However, when grafts are not feasible or desired, only the reconstruction plate is used to bridge the gap. Unfortunately, metal osteosynthesis and reconstruction plates, including titanium, exhibit adverse effects such as stress-shielding and limitations in accurate postoperative irradiation (especially with proton-beam therapy).
