Aims: The Advance Medial-Pivot total knee arthroplasty (TKA) was designed to reflect contemporary data regarding the kinematics of the knee. We wished to examine the long-term results obtained with this prosthesis by extending a previous evaluation.
Patients And Methods: We retrospectively evaluated prospectively collected data from 225 consecutive patients (41 men and 184 women; mean age at surgery 71 years, 52 to 84) who underwent 284 TKAs with a mean follow-up of 13.
We report the results at a mean of 24.3 years (20 to 32) of 61 previously reported consecutive total hip replacements carried out on 44 patients with severe congenital hip disease, performed with reconstruction of the acetabulum with an impaction grafting technique known as cotyloplasty. The mean age of the patients at operation was 46.

- 82 female patients with varying degrees of hip dislocation were studied to evaluate clinical outcomes and quality of life using the EQ-5D questionnaire at 1-2 years and after a minimum of 12 years post-surgery.
- Patients reported high quality of life scores shortly after surgery, which, although decreased over time, remained significantly above baseline levels even after many years.
- Pain and range of motion showed significant improvement post-surgery, while functional scores declined with age, indicating that total hip arthroplasty greatly enhances long-term quality of life for patients with congenital hip dislocation.
Background And Objectives: Endothelin-1 (ET-1), a potent vasoconstricting peptide, plays an important role in carcinogenesis. Previous in vitro studies have shown that colorectal cancer cells produce ET-1.
Methods: ET-1 and its receptors ET-A (ET(A) R) and ET-B (ET(B) R) were analyzed in colorectal cancer cell lines and tumors by Western blot and immunohistochemistry.
The effect of radial osteotomy on the position of the posterior interosseous nerve.
J Hand Surg Eur Vol
May 2012
The purpose of this study was to determine whether a radial shaft fracture would decrease the protection provided to the posterior interosseous nerve by the pronation maneuver during posterolateral exploration. The position of the nerve in 14 cadaveric elbows, before and after a radial osteotomy, was determined using CT scans in full supination and full pronation after injection of the nerve with radio-opaque dye. The angle formed by the olecranon, radial head and posterior interosseous nerve, and the distance between the nerve and the most lateral aspect of the radial head were measured.
