Continuous wound infusion and local infiltration analgesia for postoperative pain and rehabilitation after total hip arthroplasty.

Background: Total hip arthroplasty is one of the most common procedures in orthopedic surgery. We hypothesized that local infiltration of analgesia and continuous wound infusion of anesthetics in the first 72 hours after surgery could provide more effective postoperative analgesia with better rehabilitation.

Methods: A double-blind, randomized, controlled study was conducted with 96 patients who underwent total hip arthroplasty.

A computer-assisted navigation technique to perform bone tumor resection without dedicated software.

Purpose: In oncological orthopedics, navigation systems are limited to use in specialized centers, because specific, expensive, software is necessary. To resolve this problem, we present a technique using general spine navigation software to resect tumors located in different segments.

Materials And Methods: This technique requires a primary surgery during which screws are inserted in the segment where the bone tumor is; next, a CT scan of the entire segment is used as a guide in a second surgery where a resection is performed under navigation control.

Hemostatic matrix effects on blood loss after total knee arthroplasty: A randomized controlled trial.

Background: Total knee arthroplasty (TKA) can result in major postoperative blood loss which can impact on the recovery and rehabilitation of patients. It also requires expensive transfusions. The purpose of the study was to investigate whether a hemostatic matrix, composed of cross-linked gelatin and a thrombin solution, would reduce blood loss in patients following TKA.

Preoperative radiofrequency ablation in painful osteolytic long bone metastases.

This study aimed to determine whether Radiofrequency Ablation (RFA) followed by prophylactic internal fixation produces better palliation in terms of pain and reduces the need for blood transfusion more than radiotherapy and surgical stabilization (RT-SS). Patients with solitary long bone metastases and a pain score of 5 or more on the VAS scale were selected. Fifteen patients were treated with RFA and surgical stabilization (RFA-SS) and were compared with a matched group (15 subjects) treated by radiotherapy and surgical stabilization (RT-SS).

The use of hook plate in type III and V acromio-clavicular Rockwood dislocations: clinical and radiological midterm results and MRI evaluation in 42 patients.

Background: Acromio-clavicular (AC) joint dislocations are very common following falls on the shoulder or an overstretched hand. The best treatment for such lesions remains a matter of debate. Several studies have, however, lent support to the surgical role of the hook plate in Rockwood type III and V AC dislocations.

Clinical and radiological midterm results from using the Fixion expandable intramedullary nail in transverse and short oblique fractures of femur and tibia.

Background: A locked nail is the principal method used to eliminate rotatory components in femoral and tibial fractures. Nevertheless, weight bearing is not directed onto the fracture site, slowing down the healing process; another possibility is to use a large-diameter nail and ream the canal to obtain as much adherence as possible and increase the grip, but this can cause a number of complications. The expandable nail is a new option that in theory should remove some problems with previous techniques.
