BACKGROUND The combination of a neourethra and erection prosthesis in a single neophallus in the female-to-male transsexual remains a challenge. No good data are available on this subject. OBJECTIVE To report the outcome in 129 female-to-male transsexuals with a neophallus after the implantation of an erectile prosthesis. DESIGN, SETTING, AND PARTICIPANTS From March 1996 until October 2007,...
Total ankle replacement (TAR) has become a valuable treatment option in patients with end-stage ankle osteoarthritis. One popular 3-component system, the HINTEGRA TAR, is an unconstrained system that provides inversion-eversion stability. More natural biomechanics of the replaced ankle may be expected when anatomic considerations drive prosthesis design. The HINTEGRA prosthesis includes 2 anato...
RESULTS Eighty-nine ears in 83 patients aged 7 to 85 years were included. Transmeatal tympanoplasty was performed in 17 ears (19%). Seven ears (8%) underwent tympanoplasty with canal wall–downmastoidectomy, and 65 ears (73%) underwent canal wall–up (combined approach) tympanoplasty with mastoidectomy. The study population comprised 61 primary tympanoplasties (69%) and 28 revision cases (31%). M...
In vitro biomechanical analysis after cervical disc replacement (CDR) with a novel artificial disc prosthesis (mobile core) was conducted and compared with the intact model, simulated fusion, and CDR with a fixed-core prosthesis. The purpose of this experimental study was to analyze the biomechanical changes after CDR with a novel prosthesis and the differences between fixed- and mobile-core pr...
Anterior lumbar approach techniques for the management of discogenic back pain and placement of spinal instrumentation such as fusion and disc replacement prosthesis is becoming increasingly popular. To date, no studies have reported the clinical usage of spinal navigation with anterior lumber interbody fusion (ALIF) and total disk replacement (TDR). We describe a surgical procedure of a 35-yea...
There are no long-term published results on the survival of a third-generation cemented total shoulder replacement. We describe a clinical and radiological study of the Aequalis total shoulder replacement for a minimum of ten years. Between September 1996 and May 1998, 39 consecutive patients underwent a primary cemented total shoulder replacement using this prosthesis. Data were collected pros...
The frequency of air embolism was studied in 21 patients during total hip replacement. Two groups were examined, one having femoral shaft cement insertion by hand, the other by Exeter cement gun. Venous air embolism was common throughout the hip surgery, but was especially so during prosthesis positioning in the femoral shaft. There were fewer air emboli and cardiovascular sequelae detected in ...
OBJECTIVE To provide estimates of patient outcomes following tricompartmental knee replacement and to examine variation in outcomes due to patient and prosthesis characteristics. DATA SOURCES English-language articles identified through a computerized literature search and bibliography review. STUDY SELECTION Studies were included if they enrolled 10 or more patients at the time of initial ...
A total knee replacement is one of the most successful orthopedic procedures to enable the patient’s return to a normal, active lifestyle. The angle of the mechanical axis depends on the surgeon’s decision, which effects the strain distribution on the femoral bone and may lead to a fracture of the femur . This study evaluated the equivalent total strain on the femoral shaft under daily activiti...
