Proximal humerus fractures are prevalent in older adults, particularly women, primarily due to osteoporosis and increased fall risk. These fractures often result from low-energy falls in elderly patients, while in younger individuals, they are more likely to occur with high-energy trauma, which may involve additional injuries to soft tissue and neurovascular structures. Proper anatomical understanding, including key structures and blood supply, is crucial for effective management and to prevent complications.

Introduction: The purpose was to determine whether computed tomography (CT) Hounsfield units (HU) as a proxy for bone quality can predict postoperative complications following surgical treatment of proximal humerus fractures.
Methods: Sixty-six patients with 2-, 3-, or 4-part proximal humerus fractures who underwent surgical fixation at single institution and had complete radiographic data available were included. Radiographic measurements included the deltoid tuberosity index (DTI) on preoperative anterior-posterior shoulder radiographs, and the HU value from the surgical proximal humerus was determined by measuring the humeral head at the midaxial/coronal/sagittal CT image using a circle-type region of interest (≥35 mm2).

Introduction: Proximal humerus fractures (PHF) are common in the elderly, accounting for significant morbidity and mortality. Non-surgical treatment is a common option for low-demand elderly patients, but it can lead to unsatisfactory functional outcomes in some cases. The identification of predictive factors for poor prognosis in non-surgical management remains unclear.

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.

Background: The osteonecrosis ratio in valgus impacted fractures of the proximal humerus is low (<10 %), giving osteosynthesis all its meaning. However, the optimal fixation technique remains controversial. After recentering the humeral head, osteosuture is stable enough to allow bone healing in an adequate position as well as a good long-term shoulder functionality.

Purpose: Comminuted coronal shear fractures of the distal humerus represent rare injuries and are difficult to treat, especially comminuted capitellum and trochlear fractures (Dubberley Type III). The on-table reconstruction technique of comminuted articular fractures may be an option, although it has not been reported in the coronal shear fracture of the distal humerus. The aim of the present case series is to determine the functional and radiological outcomes of on-table reconstructed Dubberley III fractures.

Background: Acquired acromial compromise, including thinning (less than 30% of the normal acromion) or fragmentation resulting from acromiohumeral impingement or previous acromioplasty, is a concern in reverse shoulder arthroplasty (RSA). This condition may lead to shoulder pain and difficulties in arm elevation because of acromial insufficiency fracture.
Questions/purposes: (1) Do patients with acromial compromise (thinning less than 30% of normal acromion or fragmentation) have worse functional outcome scores, ROM, and strength after RSA compared with patients without acromial compromise? (2) Are patients with acromial compromise at a higher risk of complications such as acromial insufficiency fracture after RSA? (3) Do patients who develop acromial insufficiency fracture have predisposing associated factors and worse clinical outcomes?
Methods: Between January 1, 2016, and December 31, 2020, we treated 398 patients with RSA, and all patients were considered potentially eligible for this study.

Background: Avascular necrosis (AVN) of the humeral head is characterized by osteonecrosis secondary to disrupted blood flow to the glenohumeral joint. Following collapse of the humeral head, arthroplasty, namely, total shoulder arthroplasty (TSA) or humeral head arthroplasty (hemiarthroplasty), is recommended standard of care. The literature is limited to underpowered and small sample sizes in comparing arthroplasty modalities.
