Long-term data and information indicating whether minimally invasive surgery (MIS) approaches are safe and effective with total\nhip arthroplasty (THA) are lacking. Between 2004 and 2006, 75 patients with alcohol-related osteonecrosis of the femoral head\n(ONFH) who underwent 75 THAs with the two-incision approach were studied. The medical records, radiographic parameters,\nand functional outcomes were collected prospectively. All data were compared with those for matched patients who underwent\na modified Watson-Jones (WJ) approach. THA using the two-incision approach was associated with longer operation time, more\nblood loss, more lateral femoral cutaneous nerve injury, and more periprosthetic femoral fractures (...
The treatment methods used for Blauth type IIIB hypoplastic thumbs are controversial. We performed a nonvascularized,\nhemilongitudinal metatarsal bone transfer on a 5-year-old boy with a type IIIB hypoplastic thumb. Despite the childâ??s age, the\ngrowth of the thumb was confirmed and the thumb had stabilized. Moreover, growth disorder of the donor toe was not\nobserved. This method is relatively easy to perform. And donor toe deformation can be prevented, because of the preservation of\nmore than half of the metatarsal bone. In our case, the patient was 5 years of age; nevertheless, the epiphyseal line was opened\nand the grafted metatarsal bone grew. This method is useful in terms of its simplicity and prevention of postoperative complications...
Purpose: Describe the evolution of the reconstruction of meniscal rim with semitendinosus tendon in a patient\r\nwith knee pain after a subtotal meniscectomy and absence of meniscal wall.\r\nMethod: 32 years old male with a six-month history of the left knee pain after a subtotal meniscectomy. The MRI\r\nindicated a small internal meniscal remainder without posterior horn attachment. Taking this absence as a relative\r\ncontraindication for implant and meniscal transplantation, the reconstruction of a new meniscal wall with semitendinosus\r\ntendon autograft was considered. A collagen meniscal implant was attached to the new wall five months later.\r\nResults: After two years the patient referred only non specific discomfort with full pain relief in the medial compartment.\r\nThe MRI revealed integration of implants without significant degenerative changes compared to previous images.\r\nConclusions: This staged technique was designed to restore medial meniscus-like biologic tissue in a symptomatic\r\npatient following arthroscopic subtotal meniscectomy with a significant loss of the peripheral meniscus rim. Symptomatic\r\nimprovement was obtained at two years follow-up....
Research into the detrimental effects of excessive exercise has been conceptualized in a number of similar ways,\nincluding ââ?¬Ë?exercise addictionââ?¬â?¢, ââ?¬Ë?exercise dependenceââ?¬â?¢, ââ?¬Ë?obligatory exercisingââ?¬â?¢, ââ?¬Ë?exercise abuseââ?¬â?¢, and ââ?¬Ë?compulsive\nexerciseââ?¬â?¢. Among the most currently used (and psychometrically valid and reliable) instruments is the Exercise\nAddiction Inventory (EAI). The present study aimed to further explore the psychometric properties of the EAI by\ncombining the datasets of a number of surveys carried out in five different countries (Denmark, Hungary, Spain, UK,\nand US) that have used the EAI with a total sample size of 6,031 participants. A series of multigroup confirmatory\nfactor analyses (CFAs) were carried out examining configural invariance, metric invariance, and scalar invariance. The\nCFAs using the combined dataset supported the configural invariance and metric invariance but not scalar\ninvariance. Therefore, EAI factor scores from five countries are not comparable because the use or interpretation of\nthe scale was different in the five nations. However, the covariates of exercise addiction can be studied from a\ncross-cultural perspective because of the metric invariance of the scale. Gender differences among exercisers in the\ninterpretation of the scale also emerged. The implications of the results are discussed, and it is concluded that the\nstudyââ?¬â?¢s findings will facilitate a more robust and reliable use of the EAI in future research....
Introduction. Cup position is critical to stability in total hip arthroplasty and is affected by pelvis motion during positions of daily\nlife.The purpose of this study was to explicitly define the relationship between sagittal pelvic motion and resultant cup functional\nanteversion and create a tool to guide the surgeon to a patient-specific intra-operative anteversion. Materials and Methods. 10,560\ncombinations of inclination, anteversion, and pelvic tilt were generated using a geometric model. Resultant functional anteversion\nwas calculated for each iteration and variableswere correlated.Anelectronicmobile toolwas created that compares inputted patientspecific\nvalues to population-based averages to determine pelvic positions and dynamics that may lead to instability. Results. A\nthird-degree polynomial equationwas used to describe the relationship between variables.Thefreely downloadablemobile tool uses\ninput from pre-operative plain radiographic measurements to provide the surgeon a quantitative correction to intra-operative cup\nanteversion based on differences in functional anteversion compared to population-based averages. Conclusion.This study provides\na geometric relationship between planned cup position, pelvic position and motion, and the resultant functional anteversion. This\nmathematical model was applied to an electronic tool that seeks to determine an individualized intra-operative cup anteversion\nbased on measured patient-specific pelvic dynamics....
The goal of this investigation was to determine if playing or training on third-generation artificial turf (AT) surfaces increases\nthe incidence rate of injuries compared to natural grass (NG) surfaces. This was accomplished by a meta-analysis performed on\npreviously published research. Eight studies met the criteria of competitive soccer players, participation on both surfaces, and\npresentation of both exposure time and injury occurrence. Exposure time and injury incidence values were used to generate injury\nrate ratios (IRRs, AT/NG) for all injuries as well as specific injuries. Subgroup analyses were also performed by condition (match\nor training), gender, and age (youth or adult). The overall IRR was 0.86 (P < .05) suggesting a lower injury risk on AT than NG.\nHowever, there was considerable heterogeneity between studies. Analyses of individual injuries and subgroups found that in many\ncases IRR values were significantly less than 1.0. In no case was the IRR significantly greater than 1.0. Based on this, it appears that\nthe risk of sustaining an injury on AT under some conditions might be lowered compared to NG. However, until more is known\nabout how issues such as altered playing styles affect injury incidence, it is difficult tomake firmconclusions regarding the influence\nof AT on player safety....
Background: Since we are very successful in the operation of hallux valgus using a transverse subcapital\nosteotomy fixated with an intramedullary angle-stable locking plate, and a tailors bunion is\nunderstood as a reversed hallux valgus, we have applied the operation also for such indication.\nMethod: The osteotomy was carried out at a straight V. metatarsal subcapitally, and in case of an\noutwardly curved V. metatarsal at the bending location. The intramedullary plates are available in\ndifferent designs and the plate and screws disappear completely in the bone, so the soft tissues are\nnot disturbed. The head of the plate is either straight or curved in order to shift the distal fragment\nsufficiently. Results: 26 patients were operated within a period of 5 years (2008-2012). 21\npatients were followed up after an average of 34.4 months. The IM angle IV/V could be improved\nby an average of 11.76 to an average of 4.10. This is a highliy significant pre- to postoperative\ndifference of 7.66 (t = 15.07, p < 0.001). The AOFAS score was improved by an average of 42.24\npoints from 55.76 points preoperatively to 98.00 points postoperative. There was no pseudoarthrosis\nand no wound healing impairment. All patients were either satisfied or very satisfied\nwith the surgery. Conclusion: This method does not have the disadvantages of the other common\noperations of the Tailors bunion and is applied now as a standard method in this deformity....
Background: A screening of ulnar collateral ligament insufficiency is required for overhead throwers, since secondary\r\npathologic changes result from an increased elbow valgus laxity. We developed a new manual method for assessing\r\nelbow valgus laxity and investigated the reliability of this method and its correlation with ultrasonographic assessment.\r\nMethods: We defined elbow valgus laxity as the difference between the shoulder external rotation angle (ER\r\nangle) measured with the elbow in 90 degrees flexion and that measured with the elbow in extension because ER\r\nangle measured with the elbow in 90 degrees flexion includes elbow valgus laxity and ER angle with the elbow in\r\nextension does not include it. ER angle measurement with the elbow in extension involved the use of a custom\r\narm holder. Three examiners each measured elbow valgus laxity by the new method in 5 healthy volunteers.\r\nIntraobserver and interobserver reliability was evaluated by calculating the intraclass correlation coefficient. We\r\nthen assessed 19 high-school baseball players with no complaints of shoulder or elbow pain. Elbow\r\nultrasonography was performed with a 10-MHz linear transducer with the elbow in 90 degrees flexion, and the\r\nforearm in the neutral position, and the width of the medial joint space at the level of the anterior bundle was\r\nmeasured. Elbow valgus laxity assessed by ultrasonography was defined as the difference between the medial joint\r\nspace width with gravity stress and that without gravity stress. Increased elbow valgus laxity assessed by both our\r\nmethod and ultrasonography was defined as the difference between the laxity of the elbow on the throwing side\r\nand that on the contralateral side. Pearson�s correlation coefficient (r) was calculated to evaluate the relationship\r\nbetween increased elbow valgus laxity obtained by our manual method and that by ultrasonography.\r\nResults: Intraobserver reliability ranged from 0.92 to 0.98, and interobserver reliability was 0.70. The increased\r\nelbow valgus laxity assessed by our method was significantly correlated with that assessed by ultrasonographic\r\nassessment (P = 0.019, r = 0.53).\r\nConclusions: Elbow valgus laxity can be assessed by our method. This method may be useful for screening for\r\ninsufficiency of the ulnar collateral ligament....
Background: The purpose of the current study was to examine the effect of a non-invasive, home-based\nbiomechanical treatment program for patients with spontaneous osteonecrosis of the knee (SONK).\nMethods: Seventeen patients with SONK, confirmed by MRI, participated in this retrospective analysis. Patients\nunderwent a spatiotemporal gait analysis and completed the Western Ontario and McMaster University Osteoarthritis\nIndex (WOMAC) and the Short-Form-36 (SF-36). Following an initial assessment, patients commenced the\nbiomechanical treatment (AposTherapy). All patients were reassessed after 3 and 6 months of treatment.\nResults: A significant reduction in pain and improvement in function was seen after 3 months of therapy with\nadditional improvement after 6 months of therapy. Pain was reduced by 53% and functional limitation reduced\nby 43%. Furthermore, a significant improvement was also found in the SF-36 subscales, including the summary\nof physical and mental scores. Significant improvements were found in most of the gait parameters including a\n41% increase in gait velocity and a 22% increase in step length. Patients also demonstrated improvement in\nlimb symmetry, especially by increasing the single limb support of the involved limb.\nConclusions: Applying this therapy allowed patients to be active, while walking more symmetrically and with\nless pain. With time, the natural course of the disease alongside the activity of the patients with the unique\nbiomechanical device led to a significant reduction in pain and improved gait patterns. Therefore, we believe\nAposTherapy should be considered as a treatment option for patients with SONK....
The aim of this study was to assess the reliability of a novel field test of critical running speed (CS). Ten trained male distance runners completed a familiarisation trial plus three separate experimental trials on a standard 400 m athletics track. Each trial consisted of three distances (1200, 2400 and 3600 metres) that were selected to produce finishing times in the region of 3, 7 and 12 minutes respectively. Participants were instructed to cover the set distance in the fastest time possible. Participants rested for 30 minutes between efforts. Data were modelled using the linear distance-time model, described by the equation: d = (CS x t) ARC, where: d = distance run (m), t = running time (s), and ARC = anaerobic running capacity (m). Results demonstrated a coefficient of variation (CV) of 2.0% (95% confidence limit (95% CL): 1.4-3.8%) for trials 2-1 and 1.3% (95% CL: 0.9-2.4%) for trials 3-2. There was no significant difference in CS (m�·s-1) across trials (P<0.05). The limits of agreement were �±0.27 m�·s-1 of the measure for trials 2-1 and �±0.18 m�·s-1 for trials 3-2. ARC proved to be less reliable with a group CV of 18.4% (95% CL: 13.5- 39.9%) for trials 2-1 and 9.8% (95% CL: 7.0-19.6%) for trials 3-2. Although the assessment of ARC is less reliable, CV data are similar to those reported previously during laboratory-based testing....
