The indications for thoracic pedicle screw fixation have expanded over the past decade. Thoracic pedicle screws are now being used in the treatment of degenerative, traumatic, neoplastic, congenital, and developmental disorders. ⋯ With strict adherence to the surgical techniques of insertion, thoracic pedicle screw fixation is a safe and effective method of stabilization. It offers several advantages over other forms of fixation, especially in the upper thoracic spine where the options are limited.

A significant proportion of patients will experience moderate to severe pain after hip or knee replacement surgery. Multimodal pain control regimens have been developed to address this issue. ⋯ Cyclooxygenase-2 inhibitors, a class of NSAIDs, are not believed to increase the risk of bleeding and may be useful in this population of patients. However, recent research shows increased cardiovascular and renal risks with cyclooxygenase-2 inhibitors and has limited their use for postoperative pain control in joint arthroplasty patients.

Radiculopathy and the herniated lumbar disk: controversies regarding pathophysiology and management.
Lumbar disk herniation is one of the most common problems encountered in orthopaedic practice. Despite the frequency of its occurrence, however, much about lumbar disk herniation is poorly understood. It is important to review the basic and clinical science underlying the pathophysiology and treatment, surgical and nonsurgical, of this disorder.

The two-incision minimally invasive technique for total hip arthroplasty is described in detail, with attention to pearls of technique, for a prospective group of 200 patients, as well as a matched-pair group of 43 patients who underwent either the two-incision procedure or the mini-incision (single-incision posterior) procedure. The importance of a total hip critical pathway is emphasized, and the economic benefits are presented. Results reveal that the two-incision and mini-incision techniques have acceptable complication rates, are cost effective, and are beneficial to the patient, with reduced hospital stays, high patient satisfaction, and earlier return to function.

Performing hip arthroscopy with the patient in the lateral decubitus position is advantageous in aiding in visualization of the hip joint, in maneuvering instruments in obese patients, and in facilitating entry to the hip joint in patients with spurs on the anterolateral aspect of the acetabulum. The patient is placed in the lateral decubitus position with the hip on which the surgery is being performed on the top. The leg is placed in traction and a well-padded perineal post is applied for countertraction. ⋯ A regular traction table requires adjustments of the perineal and traction posts to apply traction to the leg of a patient in the lateral decubitus position. Special traction devices make setup easier. The lateral approach to hip arthroscopy provides a safe and consistent method of entering, visualizing, and performing surgical procedures on the hip.
