No benefit from perioperative intravenous lidocaine in laparoscopic renal surgery: a randomised, placebo-controlled study

There is evidence that perioperative intravenous lidocaine administration can reduce analgesic requirement, improve recovery of bowel function and shorten the length of hospital stay. Its effect in laparoscopic renal surgery has not been investigated.

[Joint preserving surgery of the adult hip: pelvic osteotomies]

Deformity and malposition of the acetabulum can occur during the development of the hip. Developmental hip dysplasia and acetabular retroversion are possible causes of osteoarthritis in the young adult. Surgical management with reorientation of the acetabulum allows causal therapy of the deformity and preservation of the native hip joint. Established techniques are the Bernese periacetabular osteotomy (PAO) and the Tönnis and Kalchschmidt triple osteotomy of the pelvis. Both techniques permit three-dimensional correction of the position of the acetabulum. Advantages and disadvantages of each technique must be considered and are summarized in the present paper. If performed early (osteoarthritis grade Tönnis 0 and 1) with correct indication and proper technique, good results can be expected.
