Femoral neck preserving stems have been developed to take advantage of the biomechanical properties of the femoral neck, and to optimise femoral anchorage and load distribution. The aim of this study was to report the clinical and radiological results in a group of 126 patients (150 hips), operated on for a total hip arthroplasty with the CFP stem. Clinical evaluation considered Harris Hip Score (HHS), thigh pain, Charnley classification, peri- and post-operative complications. Radiographic variables were stem sizing and alignment, femoral and acetabular osteolysis, the quality of cementation and restoration of the offset. The HHS at mean follow-up of 66 months was 83 points. We did not observe femoral or acetabular osteolysis, secondary malalignment or radiographic reactions, but only bone remodelling under the collar. The CFP stem must be used appropriately based on pre-operative planning (correct morphology and torsion of the femur). The surgical technique is straightforward if carried out step by step. We did not see any cases of significant limb length discrepancy.

“…It can be performed asynchronously by having the observer analyze video recordings of the subject behavior in the work environment (also called “time-action analysis”[14][15]), but it is mostly conducted by directly observing and following the subject in real-time. Subjects might feel disturbed, and sometimes an improvement in performance can be evidenced by the presence of an external observer: a phenomenon known as the Hawthorne effect 1 .…”

Time motion studies were first described in the early 20th century in industrial engineering, referring to a quantitative data collection method where an external observer captured detailed data on the duration and movements required to accomplish a specific task, coupled with an analysis focused on improving efficiency. Since then, they have been broadly adopted by biomedical researchers and have become a focus of attention due to the current interest in clinical workflow related factors. However, attempts to aggregate results from these studies have been difficult, resulting from a significant variability in the implementation and reporting of methods. While efforts have been made to standardize the reporting of such data and findings, a lack of common understanding on what “time motion studies” are remains, which not only hinders reviews, but could also partially explain the methodological variability in the domain literature (duration of the observations, number of tasks, multitasking, training rigor and reliability assessments) caused by an attempt to cluster dissimilar sub-techniques. A crucial milestone towards the standardization and validation of time motion studies corresponds to a common understanding, accompanied by a proper recognition of the distinct techniques it encompasses. Towards this goal, we conducted a review of the literature aiming at identifying what is being referred to as “time motion studies”. We provide a detailed description of the distinct methods used in articles referenced or classified as “time motion studies”, and conclude that currently it is used not only to define the original technique, but also to describe a broad spectrum of studies whose only common factor is the capture and/or analysis of the duration of one or more events. To maintain alignment with the existing broad scope of the term, we propose a disambiguation approach by preserving the expanded conception, while recommending the use of a specific qualifier “continuous observation time motion studies” to refer to variations of the original method (the use of an external observer recording data continuously). In addition, we present a more granular naming for sub-techniques within continuous observation time motion studies, expecting to reduce the methodological variability within each sub-technique and facilitate future results aggregation.

“…With regard to this, we did not find a statistical correlation between success rate and individual training in application of the CFP stem. Other groups postulated that the learning curve for using this short stem prosthesis was completed after 20 procedures regardless of the experience, and that the clinical outcome was not affected by the learning curve [21,22].…”

Short stem prostheses that preserve the femoral neck are becoming more and more popular. The CFP (collum femoris preserving) has been introduced especially for the treatment of younger patients. However, information about remodelling, complications and learning curve are thus far rare. We present a retrospective study of 155 patients (average age 59.3±9.9 years) who underwent total hip replacement with the CFP prosthesis. Follow-up was obtained 74.3±9.4 months postoperatively. The Harris hip score revealed excellent and good results in 96%. One stem had to be exchanged due to aseptic loosening revealing a survival rate of 99% and 100% for stem and cup, respectively. Radiological analysis showed typical patterns of remodelling with apearance of cortical thickening predominantly in the distal part of the prosthesis. Implant related revision rate was <1%, with further complication rate independent of the surgeon's individual experience. With regard to outcome, survivorship and complication rate, the medium-term results of the CFP prosthesis are promising.
