Purpose: The aim of this systematic review was to assess the outcome of non-vascularized iliac bone graft and vascularized iliac bone graft (VBG) in the reconstruction of mandibular defects.
Methods: An electronic search was conducted in PubMed, Google Scholar, Scopus, and Cochrane Library for relevant articles in English, French, and German languages published between 2010 and 2021 using the following keywords: ("mandibular reconstruction" [Mesh] OR "mandibular defect") AND (("deep circumflex iliac artery" OR "DCIA") OR ("non-vascularized iliac crest bone graft" OR "NVICBG") OR (("ilium" [Mesh] OR "iliac") AND ("free" OR "vascularized") AND "graft")). The National Institute of Health (NIH) quality assessment tool was used for risk of bias assessment. The final data were presented as frequencies and percentages.
Results: Initially, 58 articles were found in PubMed, 39 in Scopus, 522 in Google Scholar, and 112 in Cochrane. Finally, 13 met the eligibility criteria of the study. There were 234 patients in the NVICBG group and 89 in the VBG group. The graft failure rate ranged from 8.8 to 23% in the NVICBG group and 0-27.7% in the VBG group. In the one-year follow-up, the graft survival rate in the NVICBG group ranged from 75 to 92%, while it ranged from 73 to 99% in the VBG group.
Conclusion: No well-controlled clinical trial was found on the comparative outcome of NVICBG and VBG to reconstruct mandibular defects regarding defect size and site. The prevalence of graft failure was the same in NVICBG and VBG. The selection of graft type based on defect size needs to be more questionable.

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).

Background: Cervical spine pyogenic infection (CSPI) is a rare and challenging form of spinal infection that is typically caused by pyogenic bacteria and primarily affects the cervical vertebral bodies and surrounding tissues. Given its nonspecific symptoms, such as fever and neck pain, early diagnosis is crucial to prevent severe complications, including spinal cord injury. We report a previously unreported case of acute CSPI arising from chronic paronychia, exploring its diagnostic and therapeutic challenges through a review of the current literature.

Background: Congenital Pseudarthrosis of the Tibia (CPT) is a rare pediatric condition presenting substantial challenges for orthopedic surgeons. Aiming to achieve bone union, with subsequent complications such as refractures being common. The aim of the present study is to evaluate the results of our intentional cross-union protocol and to compare these outcomes with those obtained from our previously used techniques.

Background: While the line joining the posterior superior iliac spine (PSIS) intersects a relatively stable sacral vertebra, it does not directly facilitate the localization of lumbar interspace or assist in the positioning for neuraxial anesthesia. Our study aimed to explore the potential of the PSIS line as a reference point and to determine its practical applicability in clinical settings.
Methods: We consecutively enrolled pregnant women with gestational ages ranging from 24 to 38 weeks scheduled for magnetic resonance imaging (MRI) examination.

Background: Cancellous bone mechanical properties are directly linked to structural integrity, which is a result of bone quantity, the quality of its bone matrix, and its microarchitecture. Several studies highlighted the bone behavior under specific loads, contributing to understanding risk factors and developing more effective therapeutic strategies. The anatomy and stability of iliac bone fractures, providing insight into pelvic trauma management.
