Review Case Reports
Pelvic girdle sepsis in childhood. An illustrative case of the difficulty in diagnosis.
The child who presents with fever, limp and hip pain will often undergo multiple diagnostic procedures before a definitive diagnosis is made. We describe a diagnostically challenging case of a 14-year-old boy presenting with an atraumatic painful limp and pyrexia. Eventually the diagnosis of obturator internus muscle abscess with associated ischial osteomyelitis was made. ⋯ Symptomatology varies, clinical examination is non-specific and the diagnosis can be difficult. Haematological indices are more predictive than in cases of classical osteomyelitis or septic arthritis. Subtle features on conventional radiography and isotope bone scanning should not be overlooked while CT and MRI may be complementary in diagnosis.

Review Comparative Study
Review of methods to quantify lag screw placement in hip fracture fixation.
This review considers methods used to quantify lag screw placement within the femoral head following proximal femoral fracture. Implants used for fixation of femoral neck fractures can lead to unwanted outcomes in some patients. ⋯ These are the concepts of 'Tip Apex Distance' and Parker's ratio method of lag screw placement. We shall discuss each one in turn and their implications in terms of fracture fixation failure.
