Background: Soft tissue injuries associated with distal radius fractures have been reported by some authors.\r\nArthroscopy can be used to evaluate the condition of the articular surface and intracarpal soft tissues and as an aid\r\nto treatment. There are three intracarpal soft tissues of particular importance: the triangular fibrocartilage complex\r\n(TFCC), the scapholunate interosseous ligament (SLIL), and the lunotriquetral interosseous ligament (LTIL). The\r\npurpose of this study was to evaluate intracarpal soft tissue injuries and their relationships with fracture types\r\nduring arthroscopic surgical treatment of distal radius fractures.\r\nMethods: Eighty-nine patients in our hospital underwent surgical treatment by arthroscopy for a fracture of the\r\ndistal end of the radius. They ranged in age from 17 to 92 years (mean, 62.2 years), and comprised 20 men (mean\r\nage, 45.6 years) and 69 women (mean age, 66.5 years). The AO classification data on plain radiographs indicated A2\r\nfracture in four patients, A3 fracture in 10 patients, C1 fracture in two patients, C2 fracture in 24 patients, and C3\r\nfracture in 49 patients. Wrist arthroscopy was performed with vertical traction, and intracarpal soft tissues were\r\nexamined. For assessment of the TFCC in the radiocarpal space, the Palmar classification was used. For assessment\r\nof the SLIL and LTIL in the midcarpal space, the Geissler classification was used.\r\nResults: TFCC injury was present in 59% of cases, SLIL injury in 54.5% of cases, and LTIL injury in 34.5% of cases.\r\nOnly 17.1% of patients (14/82 patients) were negative for all three types of injury. In 81% of cases (72/89 patients),\r\nsome intracarpal soft tissue injury was present in association with the fracture.\r\nConclusions: The fracture was complicated by TFCC injury in 59% of patients, SLIL injury in 54.5% of patients, and\r\nLTIL injury in 34.5% of patients, irrespective of the fracture type....
Background: Quantitative measurement of anterior translation of the tibia (ATT) by KT 1000 is used mainly to\r\nprovide an objective assessment of knee laxity after anterior cruciate ligament (ACL) tears or ACL reconstructions.\r\nOnly few papers described its use after menisectomies in knees with intact ACL. The objective of this paper is to\r\ndetermine whether partial medial meniscectomies could induce significant immediate post-operative ATT.\r\nMethods: Thirty-two patients with a diagnosis of partial medial meniscal tear limited to the posterior horn and\r\ndocumented with magnetic resonance imaging (MRI) were assessed under anesthesia before and immediately after\r\narthroscopic meniscectomy. The assessment was performed by the same examiner by means of the MEDmetric(R)\r\nKT-1000 instrument using manual maximum (MM) force. The opposite knees were also assessed.\r\nResults: There is a significant difference between pre and post-operative KT MM mean values for the operated\r\nknees (CI: -3.933953 to -2.947297, p < 0.0001). No significance was found between the mean values for the\r\ncontralateral knees before and after the completion of the menisectomy on the operated knees (p = 0.4). For the\r\noperated knees, 14 (43.75%) had a side-to-side difference between pre-and post-operative values of more than\r\n3 mm, whereas for the contralateral knees, only 2 (6%) had the same.\r\nConclusion: Less than half of operated knees showed significant side-to-side difference values of ATT (>3 mm),\r\nimmediately after meniscectomies in unconscious patients. Our values might reflect a temporarily increase of\r\nanterior laxity under specific conditions but whether a significant laxity remains in some knees, such changes may\r\nlead to higher cartilage loading and early osteoarthritis....
Kettlebell exercises are more efficient for an athlete to increase his or her muscle strength. However it carries the\r\nrisk of injury especially in the beginners. A 39 year old gentleman came to our clinic with radial sided wrist pain\r\nfollowing kettlebell exercises. Clinically patient had swelling and tenderness over the tendons in the first dorsal\r\nwrist compartment, besides Finklesten test was positive. Patient had a decreased excursion of the thumb when\r\ncompared to the opposite side. Ultrasound/MRI scan revealed asymmetric thickening of the 1st compartment\r\nextensors extending from the base of the thumb to the wrist joint. Besides injury to the Extensor Pollicis Brevis\r\n(EPB) tendon by repetitive impact from kettlebell, leading to its split was identified. Detailed history showed that\r\nthe injury might be due to off-centre handle holding during triceps strengthening exercises. Our report stresses the\r\nfact that kettlebell users should be taught about problems of off-center handle holding to avoid wrist injuries. Also,\r\nin Kettlebell users with De Quervains disease clinical and radiological evaluation should be done before steroid\r\ninjection as this might lead to complete tendon rupture....
Background: This study examined the effects of different levels of compression (0, 20 and 40 mmHg) produced by\r\nleg garments on selected psycho-physiological measures of performance while exposed to passive vibration (60 Hz,\r\namplitude 4-6 mm) and performing 3-min of alpine skiing tuck position.\r\nMethods: Prior to, during and following the experiment the electromygraphic (EMG) activity of different muscles,\r\ncardio-respiratory data, changes in total hemoglobin, tissue oxygenation and oscillatory movement of m. vastus\r\nlateralis, blood lactate and perceptual data of 12 highly trained alpine skiers were recorded. Maximal isometric knee\r\nextension and flexion strength, balance, and jumping performance were assessed before and after the experiment.\r\nResults: The knee angle (-10�°) and oscillatory movement (-20-25.5%) were lower with compression (P < 0.05 in\r\nall cases). The EMG activities of the tibialis anterior (20.2-28.9%), gastrocnemius medialis (4.9-15.1%), rectus femoris\r\n(9.6-23.5%), and vastus medialis (13.1-13.7%) muscles were all elevated by compression (P < 0.05 in all cases).\r\nTotal hemoglobin was maintained during the 3-min period of simulated skiing with 20 or 40 mmHg compression,\r\nbut the tissue saturation index was lower (P < 0.05) than with no compression. No differences in respiratory parameters,\r\nheart rate or blood lactate concentration were observed with or maximal isometric knee extension and flexion\r\nstrength, balance, and jumping performance following simulated skiing for 3 min in the downhill tuck position\r\nwere the same as in the absence of compression.\r\nConclusions: These findings demonstrate that with leg compression, alpine skiers could maintain a deeper tuck\r\nposition with less perceived exertion and greater deoxygenation of the vastus lateralis muscle, with no\r\ndifferences in whole-body oxygen consumption or blood lactate concentration. These changes occurred without\r\ncompromising maximal leg strength, jumping performance or balance. Accordingly, our results indicate that the\r\nuse of lower leg compression in the range of 20-40 mmHg may improve alpine skiing performance by allowing a\r\ndeeper tuck position and lowering perceived exertion....
Background: The purpose of this study was to examine the association between functional movement and\r\noverweight and obesity in British children.\r\nMethods: Data were obtained from 90, 7ââ?¬â??10 year old children (38 boys and 52 girls). Body mass (kg) and height\r\n(m) were assessed from which body mass index (BMI) was determined and children were classified as normal\r\nweight, overweight or obese according to international cut offs. Functional movement was assessed using the\r\nfunctional movement screen.\r\nResults: Total functional movement score was significantly, negatively correlated with BMI (P = .0001). Functional\r\nmovement scores were also significantly higher for normal weight children compared to obese children (P = .0001).\r\nNormal weight children performed significantly better on all individual tests within the functional movement screen\r\ncompared to their obese peers (P <0.05) and significantly better than overweight children for the deep squat\r\n(P = .0001) and shoulder mobility tests (P = .04). Overweight children scored significantly better than obese in the\r\nhurdle step (P = .0001), in line lunge (P = .05), shoulder mobility (P = .04) and active straight leg raise (P = .016).\r\nFunctional movement scores were not significantly different between boys and girls (P > .05) when considered as\r\ntotal scores. However, girls performed significantly better than boys on the hurdle step (P = .03) and straight leg\r\nraise (P = .004) but poorer than boys on the trunk stability push-up (P = .014).\r\nConclusions: This study highlights that overweight and obesity are significantly associated with poorer functional\r\nmovement in children and that girls outperform boys in functional movements....
Background: Chronic Fatigue Syndrome is a debilitating disorder with an unknown aetiology but suspected\r\nmultifactorial origins. Common ââ?¬Å?triggersââ?¬Â include severe viral infections and emotional stress. Recent studies have\r\nalso found evidence of immune dysfunction and elevated inflammatory cytokines in CFS patients, but there has\r\nbeen considerable variation in the outcome measures and magnitude of these studies. Currently, there is no cure\r\nfor CFS but treatments include rest, specialist medical care, cognitive behavioural therapy, and graded (self-paced)\r\nexercise. To date, several studies have examined the efficacy of graded exercise with or without Cognitive\r\nBehavioural Therapy, with some success for patients. However, improvements in functional capacity have not\r\nnecessarily correlated with improvements in immune function, fatigue or other symptoms. This 12-week pilot trial\r\ncompares graded and intermittent exercise to normal care, measuring physiological outcomes, fatigue levels,\r\nimmune function and wellness.\r\nMethods/design: 90 patients aged between 16 to 60 years, who meet the diagnostic criteria for CFS and have\r\nbeen diagnosed by their medical practitioner, will be randomly recruited into groups consisting of Intermittent\r\nexercise, Graded exercise and usual care (Control). The outcomes will be measured pre-study (Week 0) and poststudy\r\n(Week 13). Primary outcomes are VO2peak, anaerobic threshold, peak power, levels of fatigue, immune cell\r\n(CD3+CD4+, CD3+CD8+, CD19+, CD 16+CD56+) concentrations and activation. Secondary outcomes include onset of\r\nsecondary CFS symptoms (e.g. fever, swollen lymph nodes), wellness, mood and sleep patterns. Primary analysis will\r\nbe based on intention to treat using logistic regression models to compare treatments. Quantitative data will be\r\nanalysed using repeated measures ANOVA with a linear model, and Cohenââ?¬â?¢s effect size. Qualitative data such as\r\nparticipantsââ?¬â?¢ responses (e.g. changes in mood and other reactions) following the exercise modalities will be read\r\nand sections demarcated. A code will be applied to each segment. A prevalence of codes will be considered\r\nthematically....
