“…In this study, the screws were inserted in identical synthetic cortical bone reproduction, which can be considered as a limit of the investigation, although it avoided results bias. Among the factors that were taken into consideration during this study, the influence of the screw diameter was significant, in accordance with previous findings [9]. The shape of the screw influenced the insertion torque as well, as shown in Fig.…”

“…Low insertional torque can cause poor compressive force between the plate and the bone [8]. On the other hand, excessive insertional torque can lead to the stripping of the screw, affecting its primary stability [9][10][11]. High insertional torque is also related to a greater inflammatory response of the tissue near the implant, which can lead to the failure of the implant as well [12].…”

Over the last thirty years, it has become increasingly clear the amount of bone (e.g. ‘bone quantity’) and the quality of the bone matrix (e.g. ‘bone quality’) both critically contribute to bone’s tissue-level mechanical behavior and the subsequent ability of bone to resist fracture. Although determining the tissue-level mechanical behavior of bone through mechanical testing is relatively straightforward in the laboratory, the destructive nature of such testing is unfeasible in humans and in animal models requiring longitudinal observation. Therefore, surrogate measurements are necessary for quantifying tissue-level mechanical behavior for the pre-clinical and clinical evaluation of bone strength and fracture risk in vivo. A specific implementation of indentation known as reference point indentation (RPI) enables the mechanical testing of bone tissue without the need to excise and prepare the bone surface. However, this compromises the ability to carefully control the specimen geometry that is required to define the bone tissue material properties. Yet the versatility of such measurements in clinical populations is provocative, and to date there are a number of promising studies that have utilized this tool to discern bone pathologies and to monitor the effects of therapeutics on bone quality. Concurrently, on-going efforts continue to investigate the aspects of bone material behavior measured by RPI, and the compositional factors that contribute to these measurements. There are currently two variants, cyclic- and impact- RPI, that have been utilized in pre-clinical and clinical studies. This review surveys clinical studies that utilize RPI, with particular emphasis on the clinical instrument, as well as the endeavors to understand the fundamental mechanisms of such measurements. Ultimately, an improved awareness in the tradeoffs and limitations of in vivo RPI is critical towards the effective and successful utilization of this tool for the overall improvement of fragility determination in the clinic.

“…The important factor in the success of fixation is the used implantation technique and the quality of the osseous tissue of the bone [34]. McAndrew et al [11] describe that the bone mineral density (BMD) is a widely used standard in the measurement of bone mass and can be used to identifying the bone strength. They also reported that the strength of the bone-screw interface is dependent on the local bone quality.…”

“…The use of screw advantages are it superior torsional stability, minimally invasive insertion and limited disruption of femoral head blood supply. It is also beneficial to surgeon as the use of screw will limit blood loss, operating time, and damage to the soft tissue that will promote better healing to the patient [10] The fracture fixation achievement depend on the screw-bone interface stability [11]. The stability of the fixation will support the fracture to increase it vascularity and tissue differentiation, accelerate the fracture union and promote early callus formation [12].…”

Bone fracture has become more common in this era of vehicular modernization. Internal fixation has been used in the treatment of such cases. The use of screw and plate in internal fixation has been proven to provide more stability to fracture to promote better healing. The use of screw also carries certain risk such as self-loosening that can cause non-union and prolong healing. The complication of selfloosening is studied to comprehend the danger of self-loosening in screw-bone implant. The review on self-loosening in bolted joint is done in this paper to gain better understanding on the nature of self-loosening phenomena. The factor that affects the screw selfloosening in bone is further studied in the screw-bone implant environment. The identification of the screw loosening can be done with radiography, CT scan, MRI and ultrasound. This article have done a brief review on the complication of screw self-loosening, the cause of screw loosening in bolted joint and screw-bone implant and the assessment of screw loosening done by ultrasound and radiography.

Local bone quality measurements correlates with maximum screw torque at the femoral diaphysis

Abstract: Reference Point Indentation can provide localized measurements of bone quality that may better inform surgeons of the competence of the bone-implant interface and improve effectiveness of fixation strategies particularly in patients with compromised bone quality.
