Filter by:The purpose of the study is to see if there is a connection between a proximal humerus fracture dislocation direction and the likelihood of developing avascular necrosis. Utilizing a retrospective cohort from the last ten years we hope to bring consenting patients back for a single visit to have x-rays and complete patient reported outcome measures to assess for evidence of avascular necrosis.
This clinical study will verify the clinical and radiographic performance of the prosthesis when used in human subjects over a period of 10 years. All complications will be documented.
One of the most serious sequelae of femoral neck fractures (FNFs) is avascular necrosis (AVN) and nonunion, and this translates to a significant morbidity and mortality. This study was conducted to determine the relationship between the etiologies and management of FNFs in our institution and its relationship to the development of AVN or nonunion.
Surgery is a common treatment type for damaged joints, tendons and nerves in the upper limb where conservative measures are inappropriate or have failed. These conditions are common and result in significant levels of pain and functional disability. The investigators are conducting a broad ranging study of variation in the provision of surgical treatment and factors affecting outcomes after surgical treatment of upper limb conditions. This will be a population-based study of all patients undergoing surgical treatment funded by the National Health Service (NHS) of England over a nineteen-year period. This study will help to understand the factors associated with a poor outcome following surgery, which can be shared with patients considering treatment options. The investigators will also document current and future health service burden associated with commonly performed surgical procedures including complications and repeat operations.
Purpose of Study: To identify and provide a safe, opioid-free treatment pathway for shoulder arthroplasty with a focus on perioperative pain control and postoperative symptoms from treatment
This study is a Post Market Clinical Follow-up study to fulfill the post market surveillance requirements. The data collected from this study will serve the purpose of confirming safety and performance of the TESS Shoulder System.
A multi-centre, non-comparative, prospective post-market clinical follow-up study to obtain survival, clinical and radiographic outcomes data on the Zimmer Fitmore Hip Stem.
This is a single center, prospective, randomized controlled study. The primary objective of this study is to measure migration over two years with RSA. Patients will be randomized in two arms, receiving a Taperloc Complete Reduced Distal or a Taperloc Complete Microplasty hip stem.
The study is a multi-center, prospective, non-controlled, consecutive cohort post market surveillance study. The objective of this study is to obtain survival and outcome data on the Continuum Metal Bearing System in primary total hip arthroplasty.
The purpose of this prospective study is to evaluate Zimmer® iASSIST™ with respect to radiographic, clinical and economic outcomes and compared to conventional instrumentation in primary total knee arthroplasty (NexGen or Persona knee implants).
