AI Article Synopsis
- A study evaluated 47 Exeter small stem total hip arthroplasties in 42 patients, averaging 58 years old, with an average follow-up of 8.5 years.
- The Oxford hip score improved significantly, going from a preoperative average of 47 to 17, with over 87% of patients achieving good or excellent Harris hip scores and 90% walking with little to no pain.
- While 26% of cases showed stem subsidence, there was no aseptic loosening or implant failure, leading to a 95.7% survival rate at 10 years and confirming the effectiveness of Exeter small stem implants.
Article Abstract
We carried out a prospective study of 47 Exeter (Stryker Inc, Warsaw, Ind) small stem total hip arthroplasty in 42 patients with an average age of 58 years and a mean follow-up of 8.5 years. The Oxford hip score improved from a preoperative mean of 47 to 17 at last follow-up. More than 87% patients had excellent or good Harris hip scores, and 90% were able to walk with little or no pain. Stem subsidence within the cement mantle was observed in 26% of cases, and none showed evidence of aseptic loosening or implant failure. Two stems were removed due to infection. The survival rate of this implant was 95.7% at 10 years. This first series of Exeter small stem showed excellent medium-term results, comparable to its larger counterparts.

Peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS) is a rare mature T-cell non-Hodgkin lymphoma (NHL) seen in both children and adults. While it is the most common non-anaplastic mature T-cell lymphoma of childhood, it is quite rare and therefore, the standard of care remains largely undefined. It is a disease characterized by clinical and pathological heterogeneity and is generally associated with an aggressive clinical course and poor prognosis in adults.

Recent advances in drug design and compound synthesis have highlighted the increasing need for effective methods of toxicity evaluation. A specialized force sensor, known as the light wavelength-encoded "Chinese guzheng" is developed. This innovative sensor is equipped with optical fiber strings and utilizes a wavelength-encoded fiber Bragg grating (FBG) that is chemically etched to reduce its diameter.
