    Abstract Introduction The original Harris hip score (HHS) does not contain ability to perform squatting and sitting cross legged as items in the questionnaire and hence a need was felt to modify the Harris hip score so that it could stay relevant in functional assessment of Indian patients in the rural setting. Validity, responsiveness and ceiling floor effect of the Harris hip score after internal fixation of pertrochanteric fracture has not been previously described. The objective of the study was to investigate construct validity, responsiveness and ceiling floor effects of the modified Harris hip score (mHHS). Methods For evaluation of construct validity two hypotheses were formulated: first, there would be no difference in mHHS in cohort of patients treated with short or long proximal femoral nail and second, patients younger than 65 years will have higher mHHS compared to patients older than 65 years postoperatively. Proportion of patients obtaining lowest score of 0 point (floor effect) and those obtaining highest score of 100 points (ceiling effect) was evaluated at one, three and six months postoperatively. It is recommended that the proportion of ceiling and floor effect should be lower than 15% in order to deduce satisfactory internal and content validity of an outcome instrument. Responsiveness was evaluated using distribution based methods (effect size and standardised response mean) and anchor based method (area under the curve using receiver operating curve). Ability to perform cross leg sitting and squatting at six months postoperatively were chosen as two different external anchors. Effect size and standardised response mean values higher than 0.80 and area under the curve value higher than 0.70 are indicators of adequate responsiveness of an outcome instrument. Results Eighty one consecutive patients with pertrochanteric hip fractures and treated with long and short proximal femoral nail were included in this prospective observational study. Six patients were lost to follow-up due to mortality and complete functional outcome data was available in 75 patients (92.6%). The mean age was 68 years (range: 38–89 years). The mHHS at one, three and six months postoperatively was 39.9 ± 9.5, 61.6 ± 14.7 and 81.0 ± 15.9 respectively. The improvement in mHHS was significant at all time intervals. In accordance with the hypothesis, there was no significant difference in mHHS at one, three and six months postoperatively in patients treated with short or long proximal femoral nail. In accordance with the hypothesis, patients younger than 65 years had significantly better mHHS at one, three and six months postoperatively as compared to patients older than 65 years. There were no floor or ceiling effects at one, three and six months postoperatively. mHHS showed adequate internal responsiveness (Effect size = 4.34; standardised response mean = 4.26) and adequate external responsiveness (Area under curve = 0.77 and 0.89) using different external anchors. Conclusion The mHHS has adequate construct validity, internal validity and responsiveness to evaluate functional outcome of intramedullary nail fixation in pertrochanteric hip fractures in the Indian population.

    Abstract The aim of this study was to evaluate the functional and radiological outcome of TruFit plugs. We retrospectively reviewed 10 patients who underwent treatment for a symptomatic chondral/osteochondral lesion using one or more Trufit Plugs. Full incorporation of the bony portion of the plug occurred in only 3 and partial incorporation in 7 lesions. The remaining portion of these 7 lesions looked cystic on MRI. The significance of this cystic change is not clear. Though all 10 patients showed some improvement on the IKDC scoring system but the amount of the improvement was small.

    Abstract The purpose of this study was to examine the influence of topical vancomycin on cell migration and survival of tissue healing cells. Human osteoblasts, myoblasts and fibroblasts were exposed to vancomycin at concentrations of 1, 3, 6, or 12 mg/cm 2 for either a 1-h or 48-h (continuous) duration. Continuous exposure to all vancomycin concentrations significantly reduced cell survival ( 2 (P in vivo studies are warranted to optimize the dosage of intrawound vancomycin. Highlights Continuous vancomycin exposure to concentrations ≥1 mg/cm 2 is significantly cytotoxic to in vitro osteoblasts and myoblasts, while concentrations ≥3 mg/cm 2 is significantly cytotoxic to fibroblasts. 1-h vancomycin exposure to concentrations 2 does not significantly affect cell survival or migration of in vitro osteoblasts, myoblasts, or fibroblasts. Future in vivo studies are required to optimize the clinical dosing of vancomycin application, and study its clinical effects on infection, healing, and bony fusion.

    Abstract Purpose To examine distraction-based methods for treatment of early onset scoliosis (EOS), focusing on the magnetically controlled growing rod system (MCGR) relative to traditional growing rod system (TGR). To briefly discuss internal magnetically controlled nails for bone lengthening as another application of magnetic growth modulation. Results Relative to TGR, MCGR involves fewer complications related to infection and general anesthesia because of fewer successive surgeries required. Further, MCGR accounts for better psychosocial patient outcome and potentially a lower long-term cost, mainly because of shortened periods of hospitalization. Intramedullary lengthening nails involve fewer complications compared to internal limb lengthening devices related to infections, nerve damage, shortening, improper healing, stiffness, and scarring. Intramedullary lengthening nails appear to alleviate psychosocial burden of patients especially when compared to external fixators. Conclusions Although the current gold standard for treating some types of early onset scoliosis (EOS) is the traditional growing rod system, the magnetically controlled growing rod (MCGR) system is an alternative method for treating EOS. MCGR is promising in that it involves less surgical procedures, shorter hospital stays, and lower long-term cost relative to TGR. Similarly, the use of magnetically controlled intramedullary lengthening nails is a promising alternative to the Ilizarov method for limb lengthening.

    Abstract Objective To develop a surgical technique for percutaneous upper extremity fracture fixation using a novel glass-based adhesive. Methods Three intact upper extremity cadaveric specimens with undisturbed soft tissues were obtained. Two were used to model a wrist fracture, and the third to model a proximal humerus fracture. Fractures were produced using a small osteotome in a percutaneous fashion. Banna Bone Adhesive (BBA) was delivered to the fracture site percutaneously using a 16 gauge needle under bi-planar fluoroscopic guidance. After setting of the adhesive, the specimens were dissected to qualitatively assess BBA delivery and placement. Results The adhesive could readily be delivered through the 16 gauge needle with an appropriate amount of pressure applied to the syringe. Using the fluoroscope, the adhesive could be seen to flow into the fracture site with minimal extravagation into the surrounding soft tissues. Successful bonding of the fracture fragments was observed. Conclusions Percutaneous delivery of BBA into a fracture of the distal radius and proximal humerus may be a feasible fracture fixation technique. Biomechanical testing and animal model testing are required to further develop this procedure.

    Abstract We examined differences in complication rates between obese and non-obese patients undergoing revision total hip arthroplasty. Sixty-five patients with a BMI ≥30 kg/m 2 and 54 patients with a BMI of 2 were identified. Obese patients were 2.5 times more likely to suffer a complication than non-obese (38.4% cf 14.8%, p = 0.02). Obese patients were more likely to experience dislocation, leg length discrepancy, fracture, implant loosening, infection and pulmonary embolus. The obese group had a significantly higher revision rate (12.3% cf 1.8%, p = 0.039). Obese patients should be counselled pre-operatively on their elevated risk.

  8. [해외논문]   Healing of femoral fractures by the meaning of an innovative intramedullary nail  

    Filardi, V.
    Journal of orthopaedics v.15 no.1 ,pp. 73 - 77 , 2018 ,

    초록

    Abstract In this paper, an innovative design of nail, conceived to heal fractures of long bones has been investigated. Its functioning is based essentially on sliding of conical surfaces located in a spindle and in a series of holding pins radially disposed around it. Spindle and holding pins are connected together by means of a sleeve. Medial and distal screws are not necessary. Rotational and longitudinal motions of the spindle are transformed in a radial expansion of the holding pins by the sliding of conical surfaces. A complete numerical FE model of an implanted femur was realized and analyzed by the mean of two loading configurations: LC1 by imposing a vertical load of 980 N, and LC2 by considering resultants of the muscle actions. Analyses confirmed results, in terms of mechanical performances, comparable with the others traditional systems of prosthesis.

    초록

    Abstract Background When approaching radial head and neck fractures, the decision for ORIF, resection, or arthroplasty is often performed intraoperatively. Factors that contribute include ligamentous and bony stability, cartilage injury, mechanical alignment as well as patient factors. Recent data has suggested conventional methods may not be sufficiently sensitive in detecting Essex Lopresti injuries. Here we describe an intraoperative technique that could objectively assess proximal radio-ulnar stability with subsequent disruption of the ligamentous structures. Methods Eight cadaveric specimens were used to evaluate amount of radial proximal migration between three groups of forearms. After radial head resection, proximal migration of the radial shaft was measured in three distinct groups. Group A included intact forearms, Group B included forearms with resected interosseous membranes (IOM), and Group C included forearms with resected interosseous membranes and distal radioulnar joint (DRUJ) disruptions. Results As compared to group A, group B averaged 4 mm of proximal radial migration (p 6 mm of migration (p Conclusion In the setting of a non-repairable radial head, the RAIL test may provide a more objective means of assessing for Essex-Lopresti injuries.

    Abstract Background The present study is a network meta-analysis of various routes of tranexamic acid (TXA) in patients with total hip arthroplasty (THA). Methods Randomized controlled trials and cohort studies evaluating TXA in patients with THA were included. Number of patients requiring blood transfusion was the primary outcome. Results Pooled estimate for TXA use against placebo for blood transfusion rate was 0.30 [0.23, 0.39] favoring TXA. Maximum reduction in the risk of blood transfusion was observed with topical plus intra-operative intravenous TXA. Conclusion Combined topical and intravenous TXA during surgery may perform better than other modes in patients undergoing THA.
