Changes in the femoral osteotomy level coefficient and neck shaft angle during limb lengthening with an intramedullary magnetic nail

During lengthening with the PRECICE IM magnetic nail, we investigated the effect of the osteotomy's height and of trochanteric versus piriformis entry points on the neck shaft angle. Methods The osteotomy level coefficient, a new parameter that was introduced as a way to determine the presence of an osteotomy at the proximal femur, was used as a measure. A retrospective review of all femoral lengthening treatments using the PRECICE ante grade IM lengthening nail between 2013 and 2018 was carried out. Compared to the piriformis entry point [ t = 3. 23, p = 0. 001]], the trochanteric entry point showed a greater tendency to reduce the NSA than to the piriformis entry point [ t = 3. 96, p = 0. 001]. Conclusion Proximal femur lengthening with the PRECICE IM nail reduced the NSA by a large margin and could result in Varus deformity. Compared to the piriformis entry points, the trochanteric entry points have a greater tendency to reduce the NSA.

Management of post-traumatic femoral defects with a monorail external fixator over an intramedullary nail

Purpose The management of limb-length discrepancy due to traumatic femoral bone loss is a unique challenge for surgeons. An intramedullary nail was examined by a retrospective review of the effects of post-traumatic femoral disorders treated by monorail external fixation of an intramedullary nail. Methods Eight patients were recruited from October 2015 to May 2019 with post-traumatic femoral defects that underwent surgical intervention with monorail fixator-assisted intramural nailing. According to ASAMI's classification, the primary outcome was time to bone union and bone findings. The average bone defect size was 9. 69 cm. Patients reached FWB and bone union 56. 25 weeks and 68. 83 weeks after bone transplant started, respectively, on average. Two patients' docking site non-union, five patients had pin site infections, five others had pin site infections, and two patients had osteomyelitis. Conclusion Monorail external fixation of an intramedullary nail is a safe option for post-traumatic femoral abnormalities, lowering external fixator time, and returning patients' quality of life to a level comparable to the normal population.

Use of intramedullary locking nail for displaced intraarticular fractures of the calcaneus: what is the evidence?

Introduction Intramedullary locking devices have recently been introduced as a minimally invasive way to treat displaced intraarticular fractures while still minimizing complications and improving outcomes. Methods Following a PRISMA checklist, Medline, Scopus, and EMBASE databases were searched to find studies describing the use of ILDs for treating DIACFs. The most common problems were metalware irritation and temporary nerve entrapment syndromes, followed by temporary nerve blockage, with soft tissue infections affecting 3u20135 percent of patients. Four out of eight studies were published by implant designers, and five out of five relevant conflicts of interest were reported. Conclusions At a short-term follow-up, treating DIAFCs with ILDs results in positive clinical outcomes, allowing for the restoration of calcaneal height and increased subtal joint congruency. Metalware irritation and temporary nerve entrapment symptoms are typical problems, but wound infections are less frequent than after open lateral approaches. Review of evidence level V to V studies from 2013 - Level III-V.

CT analysis of femoral malrotation after intramedullary nailing of trochanteric fractures

Purpose Functional results after internal fixation of trochanteric femoral fractures may be negatively affected by healing in a non-physiological setting can be affected by recovering in a non-physiological environment. In 101 patients, the authors conducted a prospective research focused on a CT evaluation of malrotation after intramedullary nailing of trochanteric fractures. Following trochanteric fracture surgery, we compiled the type of fracture, method of anesthesia, scheduled surgery vs. acute surgery, and the surgeon's experience as potential risk factors for leg malrotation following trochanteric fracture surgery. We noticed a more than 15% reduction in 35% of patients, and in 15 patients, the rotation was more than 25 percent. 00b0 The risk of significant internal malrotation was much higher than external malrotation. The effect of general anesthesia and the type of intertrochanteric fracture came nearest to having a significant effect on rotational error. Improper repair of a trochanteric fracture is a common problem that can result in femur malrotation.

Endocannabinoid and steroid analysis in infant and adult nails by LC–MS/MS

Stress markers analysis in keratinized matrices such as hair or nail is a common way to measure persistent stress. In addition, we wanted to investigate the suitability of the nail matrix for the detection of these stress markers in a pilot study. Each analyte, an LC/MS method was used for the simultaneous identification and quantification of four eCBs and five steroid hormones in human nails. Using 0. 5 mg of nail sample was investigated to determine the effect of nail weight on the quantification. The established workflow using a 1 hour extraction and clean-up by SLE was very effective, resulting in a short sample preparation time, according to a short sample preparation time. The combined study of eCBs and steroids from nails may provide a new perspective on stress exposure in infants and adults.

In reply to the letter to the editor regarding “Comparison of a twin interlocking derotation and compression screw cephalomedullary nail (InterTAN) with a single screw derotation cephalomedullary nail (proximal femoral nail antirotation): a systematic review and meta-analysis for intertrochanteric fractures”

The relative effects of internal fixation techniques for intertrochanteric fracture after surgery are limited to very small studies, which lead to confusion in attempts to establish evidence-based best practice. Methods We conducted a systematic review and meta-analysis of randomised controlled trials and observational studies to determine the clinical effectiveness of two commonly used intramedullary products: a twin-screw integrated cephalomedullary nail and a single-screw cephalomedullary nail in patients with intertrochanteric fractures. Patients were enrolled in six randomised controlled trials and four observational studies enrolling 970 patients with a median age of 77 years and 64% of patients being female. Conclusions Our meta-analysis shows that a twin-screw cephalomedullary nail antirotation treatment is clinically more beneficial, less revisions, and fewer patients complaining of pain are involved in less complications, fewer errors, less revisions, and fewer patients complaining about pain than a single-screw cephalomedullary nail antirotation.

Comparison of the elastic limit and yield load of nailed joints connecting solid wood and wood-based board material

To ensure the safety of timber buildings, evaluations of timber joints' lateral properties are crucial. elastic limit measurements using nailed joints are obtained in this research experimentally. Mechanical experiments determining the residual displacement after various lateral loads were carried out using six-joint specimen specifications were carried out, as well as various lateral loads with six-joint specimen specifications were conducted. The elastic limit was defined in this research as the load at which the residual displacement exceeded 5% of the nail diameter. According to the following tables, elastic limits to yield loads obtained using the optimum elasto-plastic model, method described in EN, and a 0. 5 percent offset method were 0. 55, 0. 557, and 0. 648, respectively.

Controlling the angle between the distal locking screw and tibiotalar joint tangent helps to reduce the occurrence of misalignment of distal tibial fractures treated with intramedullary nail fixation

Background studies have shown that on the coronal plane, if the direction of the distal locking screw is parallel to the tangent line of the tibiotal joint can be used to determine whether there is varus or valgus deformity after the repair of distal tibial fractures with intratemporal nail fixation. Nevertheless, there has been no study of the included angle on the sagittal plane or the integrated angle of the tangent line of the tibial joint and postoperative alignment of distal tibial fractures treated with IMN fixation, and there have been no reports on whether there is a correlation between the distal locking screw on the sagittal plane or the insertion angle of the tibial fractures treated with IMN fixation. Objective With IMN fixation of distal tibial fractures, we wanted to investigate the relationship between the angles formed by the distal locking screw and the tibiotal joint tangent, on the sagittal and coronal planes and postoperative alignment in the treatment of distal tibial fractures. Methods We conducted a retrospective review of 100 patients with distal tibial fractures treated with IMN fixation using the suprapatellar method. According to P 11. 8 u00b0, respectively, the mean LDTAs of groups B and C were 89. 5 u00b0, 92. 0, u00b0, and 85. 8 mm, respectively. The average ADTAs of groups B and C, group A, were 80. 4 1. 3 u00b0, 83. 1 u00b1 and 77. 9, respectively. P00b0 3. 7, 77. 9; respectively P00b1 2. 5. 00b0 and 77. 9 u00b0, respectively. P00b1 2. 5 u00b0, respectively.

An Innovative Post Grouting Technique for Soil Nails

This paper discusses an innovative method of executing soil nails by sectorized post grouting. Grave grout grouting is the most commonly used method of soil nail grouting, with the journal highlighting advancements in pressurized grouting. Although finding higher pullout resistance of soil nails, pressurized grouting, mainly done in single-stage grouting, does not compensate for exudation and its use in longer nail lengths is difficult, it can not be compensated for exudation. The findings reveal that sectorized post-grouted nails had higher pullout resistances than gravity grouted and single-stage grouted nails. The pullout resistance data obtained in this study can be used in future soil nail nailing operations that employ SPG.

Outcomes after primary intramedullary nail fixation of open tibial and femoral fractures in low resource settings

Introduction Open fractures are unique in the sense of urgency they bring to the injury and the therapeutic challenge they pose. Methods We prospectively reviewed primary IM nail nailing of open 1, 2 and 3A tibial and femoral fractures in our hospital in a non-modular operating room without an image intensifier. The mean time from injury to surgical debridement was 19. 6 hrs, according to the manufacturer, and the average hospital stay was 4. 1 days. The tibia was 6. 1 months and 5. 7 months for the femur, according to the Mean time to radiographic union. We conclude that primary IM nail nailing in open long bone fractures can be carried out in austere environments with good success, in expert hands if the principles are followed.
