Purpose: Bone and soft-tissue defects in the leg can be caused by high-energy trauma. One of the causes of extensive bone defects are gunshot injuries. The incidence of these has been noticeably increasing in recent years in countries with political instabilities due to the random availability of weapons. The aim of this study is to focus on the essentials of treatment of post-gunshot tibial bone loss using the Ilizarov concept.
Methods: In the period between June 2011 and July 2013, 30 patients with open tibial fractures after gunshots comprised the present study with an average follow-up of 18 months. The bone defect was associated with soft-tissue loss in 18 cases. All cases were subjected to extensive debridement of all devitalized tissues back to the healthy bone with viable soft tissue coverage. All cases were treated by the Ilizarov external fixator using the bifocal bone transport technique.
Results: The overall bone results were satisfactory in 28 cases (93.3 %). The overall functional results were satisfactory in 22 cases (73.3 %). The bone end results were significantly affected by age and smoking, while the functional end results were significantly affected by smoking, the presence of infection at the time of presentation, and complications during the procedure.
Conclusions: Bone transport is a reliable method in the treatment of gunshot bone defects of the tibia after extensive debridement of all the devitalized tissues. The Ilizarov external fixator allows the functional use of the limb throughout the course of treatment, preventing disuse osteoporosis and increasing patient satisfaction.

Introduction: Reconstructing large bone defects for lower limb salvage in the pediatric population remains challenging due to complex oncological or septic issues, limited surgical options, and lengthy procedures prone to complications. The vascularized double-barreled fibula free flap is pivotal for reconstructing large bones. In this article, we report our experience with this technique in the surgical management of pediatric tibial bone defects.

Background: The Masquelet induced membrane technique is a surgical procedure that allows the reconstruction of segmental bone defects using a relatively simple approach that requires minimal resources from both the healthcare facility and the patient. Historically applied to the lower limb, this technique is gaining increasing attention in the literature for its use in the upper limb.
Methods: A systematic review of the literature was conducted using the PubMed and Google Scholar databases to identify all studies reporting the outcomes of the Masquelet induced membrane technique in the long bones of the upper limb (humerus, radius, and ulna) with a sample size of at least 3 patients.

There are few reports that discuss the nebulous entity known as posttraumatic subacute meningitis. Herein, we describe a case where a male was found deceased with Streptococcus pyogenes meningitis 7 days after experiencing head trauma inflicted with a tow chain. Computed tomography scan prior to death revealed a scalp laceration with subcutaneous gas and a subdural hematoma.

The skeleton is highly innervated by numerous nerve fibers. These nerve fibers, in addition to transmitting information within the bone and mediating bone sensations, play a crucial role in regulating bone tissue formation and regeneration. Traditional bone tissue engineering (BTE) often fails to achieve satisfactory outcomes when dealing with large-scale bone defects, which is frequently related to the lack of effective reconstruction of the neurovascular network.

Background: The clinical evidence about alveolar ridge changes following molar extraction and how the alveolar bone morphology influences the ridge dimensional changes remains limited.
Methods: A total of 192 patients with 199 molar extractions were included in this retrospective study. Cone-beam computed tomography (CBCT) images of patients were obtained 0-3 months pre extraction and 6-12 months post extraction.
