Introduction: The reconstruction of bone defects of open lower leg fractures is challenging, and there is no established treatment strategy to date, especially in the acute phase. We report herein an 'acute Masquelet technique' for reconstructing bone defects of open lower limb fractures as the primary treatment in the acute phase.
Patients And Methods: We retrospectively analyzed the outcomes of seven lower limbs of the seven Japanese patients (five males, two females, aged 24-76 years [mean 53 years]) who underwent the acute Masquelet technique for open fractures with bone defects. We evaluated postsurgical complications including deep infection, absorption of grafted bone, and the final result of the bone union.
Results: Deep infection occurred in one of the seven limbs (14%). There was no case with absorption of grafted bone in our series. We have treated two patients who needed additional surgery for delayed bone union. Bone union was eventually obtained in all seven limbs. All of the patients became pain-free and could walk without a cane.
Conclusion: The 'acute Masquelet technique' was quite useful for reconstructing bone defects of open lower limb fractures as the primary treatment in the acute phase. We believe that this is one of the options that might be successful in the treatment of open lower limb fractures.

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).

Ataxia Telangiectasia Mutated (ATM) is a protein kinase traditionally known for its role in DNA damage response and cell cycle regulation. However, emerging research has revealed its multifaceted and crucial functions in the immune system. This comprehensive review explores the diverse roles of ATM in immune regulation, from lymphocyte development to its involvement in cancer immunotherapy.

Articular cartilage and osteochondral defect repair and regeneration presents significant challenges to the field of tissue engineering (TE). TE and regenerative medicine strategies utilizing natural and synthetic-based engineered scaffolds have shown potential for repair, however, they face limitations in replicating the intricate native microenvironment and structure to achieve optimal regenerative capacity and functional recovery. Herein, we report the development of a cartilage extracellular matrix (ECM) as a printable biomaterial for tissue regeneration.

Articular malalignment and ulnocarpal impaction can progress to osteoarthritis in the wrist. This may be triggered by tears of the scapholunate ligament (rarely the lunotriquetral ligament) or the foveal lamina of the triangular fibrocartilage complex. In the pre-degenerative stages, radiographic findings are inconclusive, and symptoms may be absent or discrete.

Rett syndrome (RS) is a rare neurodevelopmental disorder primarily caused by mutations in the X-linked methyl-CpG binding protein 2 (MECP2) gene, responsible for encoding MECP2 which plays a pivotal role in regulating gene expression. The neurological and non-neurological manifestations of RS vary widely in severity depending on the specific mutation type. Bone complications, mostly scoliosis but also osteoporosis, hip displacement, and a high rate of fractures, are among the most prevalent non-neurological comorbidities observed in girls with RS.
