This retrospective study investigated active duty soldiers with delayed definitive fixation of combat-related talus fractures. The authors predicted a longer delay to internal fixation and a correlation between the timing of fixation and development of osteonecrosis and posttraumatic arthritis. The Joint Theater Trauma Registry was queried by ICD-9 codes for talus fractures. Soldiers, ages 18 to 40, with talus fracture between 2001 and 2008 were included. Radiographs identified the injury type, Hawkins sign, osteonecrosis, and posttraumatic arthritis. Mean time to fixation was 12.9 days. Hawkins sign was observed in 59% of fractures at a mean of 7 weeks. No correlation was found between osteonecrosis or posttraumatic arthritis and open fractures, comminuted fractures, or timing of fixation. Average follow-up was 16 months. This case series has the longest mean time to fixation by more than threefold. There was no correlation of delayed timing of fixation and development of osteonecrosis or posttraumatic arthritis.

Background: Significant osseous defects or osteonecrosis, precipitated by open fractures, infections, or neoplastic conditions, represent infrequent yet critical medical conditions. The free vascularized fibular graft (FVFG) is a challenging but straightforward, reliable surgical intervention for the reconstruction of defects across various anatomical regions. This study aims to compare, quantify, and demonstrate the FVFG's versatility.

Interruption of osteoclast differentiation through zoledronate (Zol) disrupts the crosstalk between pre-osteoclasts and endothelial cells, hindering the initial angiogenic reaction following dental trauma. This disruption could therefore play a role in the pathogenesis of medication-related osteonecrosis of the jaw (MRONJ).

Background: The effective treatment of post-traumatic vertebral osteonecrosis continues to be an under discussion and controversial subject. Armed kyphoplasty with expansive intravertebral implants is an emerging procedure, which, in theory, allow for a more effective preservation of the restored vertebral height. The development of the indications for these recent devices has given rise to auspicious outcomes in vertebral non-union situations.

Post-traumatic missing talus is a rare and severe injury that often results in poor functional outcomes, with no consensus on the optimal treatment approach as strategies vary based on injury severity. We present the case of a 44-year-old male who sustained a missing talus following a high-energy motorcycle accident. After initial wound management and application of an external fixator, the patient underwent size-matched, fresh-frozen talus allograft transplantation combined with subtalar fusion.

Background: Understanding vascularity and assessing the risk of post-traumatic avascular necrosis are crucial for predicting outcomes and identifying optimal treatment options in proximal humerus fractures (PHFs). Until now, Hertel et al have been the only researchers to evaluate the intraoperative perfusion of the humeral head after fracture using Doppler flowmetry in a central single drill hole within the head. This pilot study aims to standardize the evaluation of intraoperative perfusion measurements in different areas of the humeral head in patients with PHF.
