Comparative StudyStress fractures of the femoral neck and coxa vara.
Theoretically, coxa vara substantially modifies the biomechanical conditions of the femoral neck, increasing the effect of direct muscle pull and leading to fatigue of opposing muscle groups; such modifications would appear to favour the appearance of stress fractures. ⋯ It is suggested that coxa vara predisposes to femoral neck stress-fracture.

Case ReportsMonteggia type I equivalent lesion: diaphyseal ulna and radius fractures with a posterior elbow dislocation in an adult.
A rare type I Monteggia equivalent lesion with a posterior dislocation associated with a diaphyseal radius and ulna fracture in an adult is described. The probable mechanisms of injury are speculated to include flexion of the elbow and pronation of the forearm. ⋯ Early reduction of the dislocation and rigid fixation of the fractures helped to achieve excellent results.

Improving reliability in the classification of fractures of the acetabulum.
Plain radiographs of the pelvis are routinely used in the initial assessment of patients with suspected fractures of the acetabulum. It is necessary for orthopaedic resident trainees, emergency physicians as well as orthopaedic surgeons who infrequently treat trauma patients to be able to describe these fracture patterns reliably to traumatologist orthopaedic surgeons who ultimately take over the patient care. Our purpose was two-fold: (1) to determine the reliability of the component parts of the Letournel classification of acetabular fractures involving six anteroposterior (AP) radiographic lines, and (2) to examine whether the addition of oblique radiograph views (Judet views) would improve the reliability. ⋯ In this study we report the following: (1) the reliability of the Letournel classification improves with level of training, (2) physicians with less experience with acetabular fractures have significantly better agreement in identifying fractures using the six radiographic lines on the AP film than the Letournel classification, and (3) agreement among the reviewers for the AP pelvic radiograph is not improved with additional oblique (Judet) views.

Which one is at risk in intraoperative fluoroscopy? Assistant surgeon or orthopaedic surgeon?
Orthopaedic surgeons use intraoperative portable fluoroscopy and roentgenography. The present study was an attempt to find out if there is a difference between the occupational radiation exposure to the orthopaedic surgeon and assistant surgeon in the operating room while using intraoperative fluoroscopy or radiographic control and to measure it. ⋯ Our findings show that although the radiation exposure during orthopaedic operations is below the recommendations of the European Committee on Radiation Protection, there is a higher risk of exposure for the assistant surgeon. It has to be kept in mind that there could be morphological and functional damage in cells exposed to radiation. Therefore, we should continue to use appropriate shielding precautions in view of the unknown long-term risks.

Comparative StudyWhy patients choose regional anesthesia for orthopedic and trauma surgery.
While both surgeons' and anesthesiologists' preference of regional over general anesthesia is increasing, the patients' preference remains limited. Little is known about why patients choose regional anesthesia. The aim of our study was to answer this question with regard to orthopedic and trauma surgery. ⋯ Patients choose different types of regional anesthesia for different reasons. While spinal anesthesia and femoral and sciatic block were chosen for curiosity reasons, brachial plexus block was chosen to avoid the side effects of general anesthesia. The patients' choice of regional anesthesia for orthopedic and trauma surgery is significantly influenced by the type of surgery, age, and health.
