Randomized Controlled Trial
A prospective study comparing single and double fascicular transfer to restore elbow flexion after brachial plexus injury.
The recovery of elbow flexion in upper brachial plexus injury can be achieved by the reinnervation of the biceps muscle (single reinnervation), but concomitant restoration of brachialis and biceps function (double reinnervation) has been recommended to improve elbow flexion strength. ⋯ The strength of elbow flexion did not differ significantly between the groups treated with single or double muscle reinnervation. Deterioration of handgrip, lateral pinch strength, and sensibility measured by using Semmes-Weinstein monofilaments, was temporary, resulting in low morbidity for both techniques.

Tourniquet cuff pressure and nerve injury in knee arthroplasty in a bloodless field: a neurophysiological study.
Tourniquet-related nerve injuries remain a concern in orthopedic surgery. The cuff pressures used today are generally lower, and therefore a decreasing incidence of peripheral nerve injuries might also be expected. However, there have been few neurophysiological studies describing the outcome after bloodless field surgery. We describe the results of neurophysiological examinations and report the incidence of nerve injuries after total knee arthroplasty (TKA) in a bloodless field. ⋯ When low tourniquet cuff pressures are used the risk of nerve injury is minor.

Management of neuropathic pain with methylprednisolone at the site of nerve injury.
Peripheral nerve blocks with methylprednisolone may provide effective pain therapy by decreasing ectopic neuronal discharge and the release of local inflammatory mediators at the site of nerve injury. In this study, we aimed to compare the efficacy of lidocaine alone with a combination of depo-methylprednisolone plus lidocaine in the management of neuropathic pain due to peripheral nerve damage. ⋯ Our results suggest that peripheral nerve block with 80 mg depo-methylprednisolone plus 0.5% lidocaine provides effective management in the treatment of neuropathic pain due to peripheral nerve damage.

Randomized Controlled Trial Comparative Study
Comparison of polypropylene versus polyester mesh in the Lichtenstein hernia repair with respect to chronic pain and discomfort.
Inguinal hernias are the most common operative procedure performed by general surgeons, and tension-free mesh techniques have revolutionized the procedure. While hernia recurrence rates have decreased, chronic postoperative pain has become recognized more widely. New mesh products offer the potential to decrease pain without compromising recurrence rates. Polyester mesh is a softer material than traditional polypropylene and may offer the benefit of causing less postoperative pain and improved quality of life. ⋯ Polyester mesh does not decrease the amount of chronic pain at 3 months. Outcomes with polyester mesh are comparable to polypropylene mesh for Lichtenstein inguinal hernia repair with regards to postoperative pain and quality of life. The sample size in this study was small and limits the significance of the results. Further studies are needed to find the optimal mesh for inguinal hernia repair.

Randomized Controlled Trial Comparative Study
Ultrasonographic examination of the radial and ulnar nerves after percutaneous cross-wiring of supracondylar humerus fractures in children: a prospective, randomized controlled study.
In this prospective study, we aimed to find out whether there is a change in the ultrasonographic features of the radial and ulnar nerves as well as clinical outcomes after traditional and lateral percutaneous cross-wiring of the supracondylar humerus fractures in children. Twenty-nine consecutive children with completely displaced Gartland type III supracondylar humerus fractures were treated with the traditional (group T) or lateral (group L) cross-wiring technique. Our findings showed that ultrasonographic features of the radial nerve were not changed in both groups but the ulnar nerve movement was reduced, and the diameter of major axis of the ulnar nerve during elbow flexion was larger (P=0.040) than in elbow extension in the traditional cross-wiring technique but not in the lateral cross-wiring technique. Lateral cross-wiring technique does not change the ultrasonographic features of the radial and ulnar nerves, and provides satisfactory results.
