Traumatic injury and surgical intervention about the hip joint place the arterial supply to the femoral head (FH) at risk. Compromised perfusion may lead to FH ischemia, cell death, and osteonecrosis. Progression to FH collapse may lead to pain, functional impairment, and decreased quality of life, especially in younger patients. This review describes the arterial supply to the FH, analyzes the impact of femoral neck fractures on FH vascularity, and explores the vascular implications of various surgical interventions about the hip, offering specific techniques to minimize iatrogenic damage to the vessels supplying the FH.

An 18F-FDG PET/CT was conducted on a 44-year-old man with a history of dermatomyositis and avascular necrosis of left femoral head, due to a fever of unknown origin. The scan revealed patchy and cloudy high densities within the medullary cavities of bilateral distal femur and proximal tibia, exhibiting peripheral high 18F-FDG avidity. Subsequent MRI confirmed bone infarction.

Background: Hip dysplasia (HD) is characterized by insufficient acetabular coverage of the femoral head, leading to a predisposition for osteoarthritis. While radiographic measurements such as the lateral center edge angle (LCEA) and Tönnis angle are essential in evaluating HD severity, patient-reported outcome measures (PROMs) offer insights into the subjective health impact on patients.
Aim: To investigate the correlations between machine-learning automated and manual radiographic measurements of HD and PROMs with the hypothesis that artificial intelligence (AI)-generated HD measurements indicating less severe dysplasia correlate with better PROMs.

Osteonecrosis of the femoral head can lead to end-stage osteoarthritis when left untreated. The incidence has been on the rise since the onset of the COVID-19 pandemic. Core decompression of the femoral head is usually the first line of surgical treatment when conservative options fail.

The original LaPrade technique for anatomic reconstruction of the posterolateral corner of the knee uses two separate allografts. More recently, a modification of this technique, using an adjustable-length suspension device with a cortical button for tibial fixation, allows anatomic reconstruction with a single semitendinosus autograft. This modification is of utmost relevance when sources of allograft are not available for multiligament knee reconstruction.

The management of slipped capital femoral epiphysis (SCFE) has been completely transformed by modified Dunn osteotomy, a subcapital realignment osteotomy achieved through a safe surgical dislocation technique originally described by Ganz. The purpose of this study was to evaluate the clinical and radiological outcomes of patients with moderate to severe SCFE after modified Dunn osteotomy. A total of 15 patients (16 hips, with one bilateral case; 12 males, 3 females) aged from 10.
