Mechanical Properties of the Human Tibial and Peroneal Nerves Following Stretch With Histological Correlations.

Despite the extensive literature regarding peripheral nerve stretch injuries, there are few studies that compare the nerve histology with the mechanical properties in humans. There is clinical evidence suggesting that the peroneal nerve is at greater risk for injury compared to the tibial nerve following total hip arthroplasty and hip trauma. We examined the two nerves from fresh human cadavers with or without controlled stretch.

New Single-stage Double Osteotomy for Late-presenting Infantile Tibia Vara: A Comprehensive Approach.

Background: Successful surgical treatment of late-presenting infantile tibia vara (ITV) patient requires the correction of oblique deformities. The purpose of this study was to report on a new comprehensive approach to correct and prevent recurrence of these deformities with a single procedure.

Methods: Medical records of 23 consecutive children (7 to 18 y) with advanced ITV (29 knees) were retrospectively reviewed after a mean of 7.

Mutant SOD1 prevents normal functional recovery through enhanced glial activation and loss of motor neuron innervation after peripheral nerve injury.

Background: Amyotrophic lateral sclerosis (ALS) is poorly understood with no effective therapeutics. One long entertained observation is that ALS may be precipitated focally by nerve injury. Many patients with ALS are athletes or veterans, and some have suffered nerve injuries at the site where ALS first presents.

Knee Arthrodesis Outcomes After Infected Total Knee Arthroplasty and Failure of Two-stage Revision With an Antibiotic Cement Spacer.

Background: Reinfected total knee arthroplasty can be managed with a second two-stage exchange or a knee arthrodesis procedure.

Methods: Twenty-three patients with knee arthrodesis after failed exchange arthroplasty for infection were reviewed. Patients were managed with a staged protocol of implant extraction, débridement, and implantation of an antibiotic spacer, with subsequent arthrodesis.

Blood Transfusion After Primary Total Hip Arthroplasty: National Trends and Perioperative Outcomes.

The purpose of this study was to quantify the changes in transfusion rates, both allogeneic blood transfusion (ALBT) and autogenic blood transfusion (ATBT) on a national scale, and determine patient factors associated with transfusions. The National Hospital Discharge Survey was evaluated between 2001 and 2010 for primary total hip arthroplasty (THA) patients and categorized on the basis of transfusion necessity, type, and comorbidity burden. A logistic regression comparison of ALBT, ATBT, and nontransfused patients was performed with respect to patient demographics and in-hospital complications.

Revision total hip arthroplasty in the United States: national trends and in-hospital outcomes.

Purpose: With the increasing number of primary total hip arthroplasties (THA) being performed, the frequency of revision surgery is also expected to increase. We analysed the immediate in-hospital complications and epidemiologic data of 3,469 revision and 18,186 primary THA cases.

Methods: The National Hospital Discharge Survey (NHDS) was evaluated between 2001 and 2010 for patients who underwent revision and primary THA.
