Predictive factors influencing fast track rehabilitation following primary total hip and knee arthroplasty.
Fast track rehabilitation after primary total hip (THR) and total knee replacement (TKR) is gaining popularity. We performed a prospective clinical trial to identify predictive factors for successful fast track rehabilitation. ⋯ Successful fast track rehabilitation is possible without pre-selection and does not seem to compromise clinical safety. However, a good social and physiotherapy community set-up should be available. The identified predictive factors could be helpful to identify candidates for fast track rehabilitation.

A biomechanical study on preloaded compression eVect on headless screws.
Commonly used headless design screws such as Acutrak and Herbert screws have limited compressive effect on short fragment fixation. Therefore, we investigated whether preloaded compression techniques could be helpful in improving the compression effect. ⋯ Preloaded compression technique was successful in attaining maximum compression rate. During trailing-side insertion, constant pitch design failed to keep compression rate. Variable pitches can be useful to preserve or increase compression rate. In addition, sleeve usage may be more advantageous in thin fragment fixation.

Case ReportsRemoval of broken solid femoral nail: a modified bent tip guide wire technique.
A broken solid femoral nail can be challenging to remove. We describe a modified bent tip guide wire technique for extraction of a broken solid retrograde femoral nail from the proximal femur. The broken nail was removed successfully through the original retrograde entry point to allow for an exchange femoral nailing in a patient with a hypertrophic non-union. This novel technique avoids any additional exposure other than that required to remove and insert the nail.

Quantitative anatomic basis of antegrade lag screw placement in posterior column of acetabulum.
Lag screw fixation has been recommended for treatment of acetabular and pelvic fracture for several years. The aim of the present study was to determine the projection of the axis of the posterior column on the inner table of the iliac wing in the supra-acetabular region. ⋯ The present study describes a safe anchor path of antegrade lag screw fixation in the posterior column. Insertion of the lag screws of adequate length is possible in the posterior column along its functional axis.
