Provide the state of the art concerning (1) biology and aetiology, (2) classification, (3) clinical assessment and (4) conservative treatment of lower limb muscle injuries (MI) in athletes. Seventy international experts with different medical backgrounds participated in the consensus conference. They discussed and approved a consensus composed of four sections which are presented in these documents. This paper represents a synthesis of the consensus conference, the following four sections are discussed: (i) The biology and aetiology of MIs. A definition of MI was formulated and some key points concerning physiology and pathogenesis of MIs were discussed. (ii) The MI classification. A classification of MIs was proposed. (iii) The MI clinical assessment, in which were discussed anamnesis, inspection and clinical examination and are provided the relative guidelines. (iv) The MI conservative treatment, in which are provided the guidelines for conservative treatment based on the severity of the lesion. Furthermore, instrumental therapy and pharmacological treatment were discussed. Knowledge of the aetiology and biology of MIs is an essential prerequisite in order to plan and conduct a rehabilitation plan. Another important aspect is the use of a rational MI classification on prognostic values. We propose a classification based on radiological investigations performed by ultrasonography and MRI strongly linked to prognostic factors. Furthermore, the consensus conference results will able to provide fundamental guidelines for diagnostic and rehabilitation practice, also considering instrumental therapy and pharmacological treatment of MI. Expert opinion, level IV., Competing Interests: Competing interests: None declared.

Purpose: Multiligamentous injury to the anterior cruciate ligament (ACL) and the posterior cruciate ligament (PCL) is an uncommon but debilitating event. Patients with combined ligament injuries typically complain of painful, debilitating knee instability that restricts their sports and daily activities. The purpose of this retrospective study was to evaluate functional and clinical outcomes of patients with chronic ACL and PCL deficiency who underwent simultaneous single-stage arthroscopic reconstruction of the central pivot., Methods: Medical records of 20 consecutive patients with chronic ACL and PCL deficiency who underwent simultaneous single-stage arthroscopic reconstruction of the central pivot were retrospectively reviewed. All patients had received either an allograft (group A) or a semitendinosus-gracilis graft for ACL repair and a bone-patellar tibial-bone graft for PCL repair (group B). Functional outcomes, after the initial follow-up period at 24-month FU, were assessed with concentric isokinetic knee extensor-flexor testing at 60 and 180°/s. The secondary aim was to compare long-term clinical recovery by the administration of the IKDC (International Knee Document Committee) Knee Ligament Evaluation Form, the Lysholm Knee Scoring Scale and the Cincinnati Knee Rating Scale., Results: The mean per cent quadriceps strength deficit in the operated as compared to the healthy knee was 13.5 % in group A and 15 % in group B (angular velocity 60°/s) and 13.5 % in group A and 9.4 % in group B (angular velocity 180°/s). The mean per cent flexor strength deficit in the operated as compared to the healthy knee was 10.4 % in group A and 12.3 % in group B (angular velocity 60°/s) and 12.2 % in group A and 9 % in group B (angular velocity of 180°/s). The flexor-quadriceps ratio was 49.4 % in group A and 48.8 % in group B in the healthy knee and 53.2 % in group A and 53.8 % in group B in the operated knee (angular velocity 60°/s) and 63.9 % in group A and 60.7 % in group B in the healthy knee and 65 % in group A and 64.9 % in group B in the operated knee (angular velocity 180°/s). Lysholm outcome was 93.9 ± 3.9 in group A and 89.1 ± 7.6 in group B (n.s). Cincinnati score was 89.6 ± 7.3 in group A and 91.0 ± 6.9 in group B (p = 0.791). IKDC results were group A in six patients (60 %), group B in three patients (30 %) and group C in one patient (10 %) in the allograft group and group A in seven patients (70 %) and group B in three patients (30 %) for autologous group., Conclusions: The results of this study suggest that one-stage arthroscopic bicruciate ligament reconstruction can restore good knee joint function. Surgical treatment should be followed by a comprehensive rehabilitation programme with specific goals, objectives and strategies, including pain management and assessment of progress in recovery of joint function and perception of knee stability., Level of Evidence: Retrospective case series, Level IV.

Muscle injuries are frequent in athletes. Despite their high incidence, advances in clinical diagnostic criteria and imaging, their optimal management and rehabilitation strategies are still debated in literature. Furthermore, reinjury rate is high after a muscle lesion, and an improper treatment or an early return to sports can increase the rate of reinjury and complications. Most muscle injuries are managed conservatively with excellent results, and surgery is normally advocated only for larger tears. This article reviews the current literature to provide physicians and rehabilitation specialists with the necessary basic tools to diagnose, classify and to treat muscle injuries. Based on anatomy, biomechanics, and imaging features of muscle injury, the use of a recently reported new classification system is also advocated.

Saliva represents a low stress, not-invasively collected matrix that allows steroid hormone monitoring in athletes by reflecting type, intensity and duration of exercise. Whole body cryotherapy (WBC) consists of short whole-body exposures to extremely cold air (-110° to -140°C) which, despite being initially used to treat inflammatory diseases, is currently acquiring increasing popularity in sports medicine. Cryostimulation practice is now widely accepted as an effective treatment to accelerate muscle recovery in rugby players. The aim of this work was to study the changes of steroid hormones in saliva of rugby players after both 2 and 14 consecutive WBC sessions, in order to investigate the effects of the treatment on their salivary steroid hormonal profile. Twenty-five professional rugby players, belonging to the Italian National Team, underwent a 7-day cryotherapy protocol consisting of 2 daily sessions. Saliva samples were taken in the morning prior to the start of the WBC, in the evening after the end of the second WBC, and in the morning of the day after the last WBC session. The samples were analyzed for cortisol, DHEA, testosterone and estradiol using competitive enzyme-linked immunosorbent assays. Cortisol and DHEA showed a reduction already after the 2 WBC sessions of the first day; after 14 consecutive WBC sessions cortisol, DHEA, and estradiol levels decreased, while testosterone increased as did the testosterone to cortisol ratio. These results were confirmed by the fact that the majority of subjects showed variations exceeding the critical difference (CD). In conclusion, we found that WBC acutely affects the salivary steroid hormone profile, and the results are evident already after only one twice-daily session. Most significantly, after one-week of consecutive twice-daily WBC sessions, all the hormones were modified. This is the first experimental report that links changes in the hormonal asset to WBC.

Background: The incidence rate of muscle injuries and re-injuries in professional elite soccer players actually is very high and may interfere with the fate of a championship., Purpose: To investigate the effect of a two-tiered injury prevention programme on first injury and re-injury incidence in top level male soccer players. Study design., Case Series Study: Muscle injuries and re-injuries sustained by a group of 36 soccer player of an italian elite soccer team have been collected during 2010-2011 season. These data have been compared with those collected during the previous season in the same elite soccer team., Results: A total of 64 injuries occurred, 36 (56%) of which during practice and 28 (44%) during matches. Muscle injuries accounted for 31.3% of the total (n=20), 70% (n=14) of which occurred during practice and 30% (n=6) during matches. Hamstring were the muscles most often injured (n=11) In all, 3 re-injuries occurred (15% of muscle injuries). No early re-injuries occurred. The incidence was 2.5 injuries/1000 hours and the burden was 37 days absence/1000 hours., Conclusions: Through the implementation of a group and personalized injury prevention program, we were able to reduce the total number of muscle injuries and days absent because of injury, in a team of elite soccer players, as compared to the previous season. Specifically, muscle injuries accounted for 31% of all injuries, as compared to 59% of all injuries sustained by the team during the previous season. The number of injuries/1000 hours of exposure was reduced by half (from 5.6 to 2.5) and the days absent/1000 hours fell from 106 to 37.

Muscle injuries are frequent in high demand sports. No guidelines are available in the scientific literature. ISMuLT, the "Italian Society of Muscles, Ligaments and Tendons", in line with its multidisciplinary mission, is proud to cover this gap.

Whole body cryotherapy (WBC) consists of a brief exposure to extreme cold air (-110°C) in a controlled chamber and it is applied in sports medicine to improve recovery from musculoskeletal trauma. The aim of this study is to better define the beneficial effect of WCB on the musculoskeletal system of athletes, in particular on bone remodelling. Remodelling osteoimmunological biomarkers OPG, RANKL and RANK were measured after WBC treatment in 10 male rugby players randomly selected from the Italian National team. OPG levels were increased significantly, supporting the view that WBC induces an osteogenic effect. Further studies evaluating the effect of WBC on bone metabolism are desirable., (Copyright © 2012 Elsevier Ltd. All rights reserved.)

Cold-based therapies are commonly applied to alleviate pain symptoms secondary to inflammatory diseases, but also to treat injuries or overuse, as done in sports rehabilitation. Whole body cryotherapy, a relatively new form of cold therapy, consists of short whole-body exposure to extremely cold air (-110°C to -140°C). Cryostimulation is gaining wider acceptance as an effective part of physical therapy to accelerate muscle recovery in rugby players. The aim of this study was to evaluate the effect of repeated cryostimulation sessions on the hematological profile and martial status markers in professional rugby players. Twenty-seven professional rugby players received 2 daily cryostimulation treatments for 7 consecutive days. Blood samples were collected before and after administration of the cryotherapic protocol and hematological profiles were obtained. No changes in the leukocyte count or composition were seen. There was a decrease in the values for erythrocytes, hematocrit, hemoglobin and mean corpuscular hemoglobin content, and an increase in mean corpuscular volume and red cell distribution width. Platelet count and mean volume remained unchanged. Serum transferrin and ferritin decreased, while soluble transferrin receptor increased. Serum iron and transferrin saturation were unchanged, as was reticulocyte count, whereas the immature reticulocyte fraction decreased substantially. In conclusion, in this sample of professional rugby players, cryostimulation modified the hematological profile, with a reduction in erythrocyte count and hemoglobinization paralleled by a change in martial status markers.

Two-stage revision is one of the most widely accepted procedures to eradicate infection and restore function in infected knee prosthesis; while the use of an articulated spacers is advocated by many as a means to preserve function between stages, no data are available regarding gait parameters after spacer implant. The aim of present study was to assess and compare the gait parameters of patients with articulated knee spacers with a normal reference population and with the sound limb. Computerised gait analysis, was performed 8 to 14 weeks after the infected knee prosthesis had been removed and a preformed, articulated, knee spacer had been implanted, in 10 consecutive patients. Kinematic data show a mean gait velocity reduction of 70% and a decrease of the range of motion of the operated knee of 59%, compared with controls. While ground reaction forces were only slightly reduced, frontal and sagittal moments and calculated powers around the affected knees were near zero or zero. Our findings point out the ability of a preformed articulated spacer to preserve, although reduced, the normal gait parameters and joint range of motion and the capacity of the human body to provide useful postural modifications, even in the absence of the proprioceptive input from a normal knee or from a traditional total knee replacement., (Copyright © 2011 Elsevier B.V.

Objective: To generate data on optimal shoulder position comparing two ultrasound-guided extracorporeal shock wave therapy techniques for the treatment of calcifying tendinitis of the shoulder., Design: Random assignment to two groups of treatment with three months follow-up., Setting: The data were collected in outpatients., Subjects: Thirty-five subjects affected by calcifying tendinitis of the shoulder were examined., Interventions: Each subject received three sessions of ultrasound-guided extracorporeal shock wave therapy (performed weekly). Neutral position technique was used in group A (n = 17, mean age 53 ± 9.2 years) and the hyperextended internal rotation technique was used in group B (n = 18, mean age 52.2 ± 10.8 years)., Main Outcome Measures: The Constant and Murley method and radiographs were used to evaluate each subject before the treatment and at three months follow-up., Results: There were no significant differences between changes in Constant total score and pain, activity of daily living and range of motion subscales of the two groups. Only the pain subscale showed a significant difference in favour of group B. Significant differences in the radiographic outcome were observed between the two groups: the percentage of total or subtotal resorption of the calcified deposits was 35.3% in group A (neutral position technique) versus 66.6% in group B (hyperextended internal rotation technique). The resorption of the calcific deposit positively influenced the clinical outcome., Conclusions: Positioning the shoulder in hyperextension and internal rotation during extracorporeal shock wave therapy seems to be a useful technique to achieve resorption of calcific deposits.

Aim: The efficacy of PRP in the treatment of tendinopathies has been already studied both in in vitro and in clinical studies. This paper describes the local and the systemic effects of US-guided autologous PRP (Platelet Rich Plasma) injections in chronic tendinopathies in sportspersons., Methods: Fifteen patients (13 male, 2 female) between 17 and 68 years old, affected by chronic tendinopathies at different sites were treated with an echographically guided injection of autologous PRP within the pathological area of the tendons. VISA score and MRI data were collected pre interventions and after 90 days and 24 months from treatment. Changes in different inteleukins (ILs), tumour necrosis factor α (TNF α), interferon γ, vascular endothelial growth factor (VEGF), endothelial growth factor (EGF), chemokine (C-C motif) ligand 2 (CCL2), were analysed at four time points in the peripheral blood of five patients., Results: After 90 days the VISA score significantly improved from 36±12 (range 21-64) to 74±17 (range 40-92). Reduction of irregularities was found in 80% of the tendons. After 24 months patients reported an average VISA score of 73±16 (range 42-100). No changes in IL, TNF α and interferon γ were observed. VEGF, EGF and CCL2 decreased progressively from 30m to 3 h after the treatment and returned to near the baselines after 24 h., Conclusion: PRP injection allow an improvement of the clinical symptomatology, which is well maintained at least for two years from treatment. The PRP-based local therapy could influence systems homeostasis and antidoping evaluations, but, in our opinion, it doesn't represent a doping substance in itself.

The single-bundle ACL reconstruction ensures good outcomes and it is a well-established and widespread technique. Nevertheless, some patients still present residual pain and instability. Recent studies have showed that the double-bundle technique restores better natural ACL-fitting kinematics. Long-term clinical studies comparing the two surgical techniques are not frequent and there is no instrument to evaluate function and kinematics during the knee rotation in vivo. In this randomised prospective study performed on sportive people, we compare the BPTB single-bundle ACL reconstruction technique, which is the most common surgical technique performed on these patients' category, with the ACL double-bundle reconstruction technique (DB), in order to evaluate possible differences between the groups. Comparing the two groups, no statistically significant difference regarding the post-operative Lysholm score (p=0.368) the Tegner activity scale (p=0.519) and the arthrometric evaluation with KT-1000 (p=0.74) have been observed. On the contrary, the IKDC evaluation showed a statistically significant difference (p=0.004) better results of the DB group. Moreover, as assessed by the Tegner activity scale, only patients of the DB group were able to return to sports at a pre-injury level. Our data suggest that the double bundle ST/G ACL reconstruction technique results into slightly better outcome than the traditional technique of single-bundle BPTB. The verification and quantification of the advantages of this technique is anticipated with future studies focusing to the accurate measurement of knee rotation during different activities., (Copyright © 2010 Elsevier Ltd.

Cold therapy is commonly used as a procedure to relieve pain symptoms, particularly in inflammatory diseases, injuries and overuse symptoms. A peculiar form of cold therapy (or stimulation) was proposed 30 years ago for the treatment of rheumatic diseases. The therapy, called whole-body cryotherapy (WBC), consists of exposure to very cold air that is maintained at -110 degrees C to -140 degrees C in special temperature-controlled cryochambers, generally for 2 minutes. WBC is used to relieve pain and inflammatory symptoms caused by numerous disorders, particularly those associated with rheumatic conditions, and is recommended for the treatment of arthritis, fibromyalgia and ankylosing spondylitis. In sports medicine, WBC has gained wider acceptance as a method to improve recovery from muscle injury. Unfortunately, there are few papers concerning the application of the treatment on athletes. The study of possible enhancement of recovery from injuries and possible modification of physiological parameters, taking into consideration the limits imposed by antidoping rules, is crucial for athletes and sports physicians for judging the real benefits and/or limits of WBC. According to the available literature, WBC is not harmful or detrimental in healthy subjects. The treatment does not enhance bone marrow production and could reduce the sport-induced haemolysis. WBC induces oxidative stress, but at a low level. Repeated treatments are apparently not able to induce cumulative effects; on the contrary, adaptive changes on antioxidant status are elicited--the adaptation is evident where WBC precedes or accompanies intense training. WBC is not characterized by modifications of immunological markers and leukocytes, and it seems to not be harmful to the immunological system. The WBC effect is probably linked to the modifications of immunological molecules having paracrine effects, and not to systemic immunological functions. In fact, there is an increase in anti-inflammatory cytokine interleukin (IL)-10, and a decrease in proinflammatory cytokine IL-2 and chemokine IL-8. Moreover, the decrease in intercellular adhesion molecule-1 supported the anti-inflammatory response. Lysosomal membranes are stabilized by WBC, reducing potential negative effects on proteins of lysosomal enzymes. The cold stimulation shows positive effects on the muscular enzymes creatine kinase and lactate dehydrogenase, and it should be considered a procedure that facilitates athletes' recovery. Cardiac markers troponin I and high-sensitivity C-reactive protein, parameters linked to damage and necrosis of cardiac muscular tissue, but also to tissue repair, were unchanged, demonstrating that there was no damage, even minimal, in the heart during the treatment. N-Terminal pro B-type natriuretic peptide (NT-proBNP), a parameter linked to heart failure and ventricular power decrease, showed an increase, due to cold stress. However, the NT-proBNP concentrations observed after WBC were lower than those measured after a heavy training session, suggesting that the treatment limits the increase of the parameter that is typical of physical exercise. WBC did not stimulate the pituitary-adrenal cortex axis: the hormonal modifications are linked mainly to the body's adaptation to the stress, shown by an increase of noradrenaline (norepinephrine). We conclude that WBC is not harmful and does not induce general or specific negative effects in athletes. The treatment does not induce modifications of biochemical and haematological parameters, which could be suspected in athletes who may be cheating. The published data are generally not controversial, but further studies are necessary to confirm the present observations.

Muscle strains are one of the most common sports-induced injuries. Depending on the severity and location of the muscle strain, different treatment approaches can be taken. This review highlights recent trends in conservative, pharmacologic, and surgical approaches to the management of sports-induced muscle injuries as presented at a symposium held during the 93rd Annual Congress of the Italian Society of Orthopedics and Traumatology (SIOT) in Rome, Italy in November 2008. Conservative approaches now include growth factor therapy and administration of autologous platelet-rich plasma during the early postinjury period; however, its use is currently considered a doping violation under the World Anti-Doping Agency code, therefore restricting its use to nonelite sports people only. Topical anti-inflammatory therapy is a promising therapeutic strategy, since it allows local analgesic and anti-inflammatory effects while minimizing systemic adverse events. As the drug delivery system is critical to clinical effectiveness, the advent of a new delivery system for ketoprofen via a new-generation plaster with a marked increase in tissue penetration and a clinical efficacy comparable with that of oral administration, provides a viable option in the treatment of single sport lesions. Surgical treatment of muscle lesions is less common than conservative and topical therapies and indications are limited to more serious injuries. Presentations from SIOT 2008 show that advances in our understanding of the healing process and in conservative, pharmacologic, and surgical treatment approaches to the management of sports-induced muscle strains contribute to better clinical outcomes, faster healing, and a swifter return to normal training and activity levels.

Whole-body cryotherapy refers to brief exposure to very cold air for treating symptoms of various illnesses. In sports medicine, whole-body cryotherapy is administered to improve recovery from muscular trauma. As specific studies are lacking, we measured cardiac markers in 10 top-level rugby players of the Italian National team before and after a 1-week course of daily sessions of whole-body cryotherapy. All subjects continued with the same training workload as that of the previous weeks. N-terminal pro B-type natriuretic peptide (NTproBNP) levels increased but remained within the normal range, whilst troponin I (TnI) and high sensitivity C-reactive protein (hsCRP) were unchanged. Whole-body cryotherapy did not impair cardiac function in this sample of elite athletes.

Background: Revision of an anterior cruciate ligament reconstruction is a complicated and delicate clinical procedure whose results, theoretically, are less satisfactory than those of the first operation., Hypothesis: The outcome of a revised anterior cruciate ligament surgery is comparable to primary anterior cruciate ligament reconstruction, with a rate of success around 70% to 80%., Study Design: Case series; Level of evidence, 4., Methods: A total of 66 revisions of anterior cruciate ligament reconstructions were carried out from September 2000 to September 2004. Patients with concomitant instability and those with alterations in the weightbearing axis of the lower limbs were not included. Sixty patients were followed from 24 to 72 months: 50 clinically and 10 by a phone interview. Six patients were lost to follow-up due to changes of address., Results: Lysholm scores were 57% excellent (95-100 points), 13% good (84-94 points), 22% fair (63-83 points), and 8% poor (<64 points). A total of 68% of patients had negative Lachman tests, 20% had positive tests with a hard end point, 10% had positive results, and 2% had very positive results. Stabilometric evaluation with the KT-1000 arthrometer at the maximum load showed that 56% of patients had <3 mm side-to-side difference, 34% had between 3 and 5 mm, and 10% had 6 to 10 mm. The International Knee Documentation Committee scores were 36% excellent (class A), 46% good (class B), and 18% fair (class C). The percentage of patients who resumed sport at the same level was 78%, compared with 58% after their primary reconstruction., Conclusion: The results of these anterior cruciate ligament reconstruction revision surgeries are close to those achieved by other series of primary reconstructions with a little less satisfactory results. We attribute the high success rate to the strict application of the same technique and the confinement of revision to motivated patients. It should be noted, however, that follow-up is only at the midterm stage (mean, 41.9 months).

Objective: To describe and compare two extracorporeal shock wave therapy techniques for the treatment of painful subcalcaneal spur., Design: Random assignment to two groups of treatment with two and eight months follow-up., Setting: The data were collected in outpatients., Subjects: Forty-five subjects with a history of at least six months of heel pain were studied., Interventions: Each subject received a three-session ultrasound-guided extracorporeal shock wave therapy (performed weekly). Perpendicular technique was used in group A (n=22, mean age 59.3 +/- 12 years) and tangential technique was used in group B (n= 23, mean age 58.8 +/- 12.3 years)., Main Outcome Measures: Mayo Clinical Scoring System was used to evaluate each subject before the treatment and at two and eight months follow-up., Results: Mayo Clinical Scoring System pretreatment scores were homogeneous between the groups (group A 55.2 +/-18.7; group B 53.5 +/- 20; P>0.05). In both groups there was a significant (P<0.05) increase in the Mayo Clinical Scoring System score at two months (group A 83.9 +/- 13.7; group B 80 +/- 15,8) and eight months (group A 90 +/- 10.5; group B 90.2 +/-8.7) follow-up. No significant differences were obtained comparing the Mayo Clinical Scoring System scores of the two groups at two and eight months follow-up., Conclusions: There was no difference between the two techniques of using extracorporeal shock wave therapy. The tangential technique was found to be better tolerated as regards treatment-induced pain, allowing higher energy dosages to be used.

The principal source of increased turnover of erythrocytes in athletes is sport hemolysis, the intravascular hemolysis that characteristically occurs with athletic performance in sport. The use of the parameter mean sphered cell volume (MSCV), automatically measured by means of the Coulter LH750, could be useful for diagnosing the presence of sport hemolysis. We studied the behavior of MSCV and mean corpuscular volume (MCV) in 30 top-level rugby players who underwent a heavy training session followed by 3 different recovery methods, administered to 3 subgroups of 10 athletes. We tested the use of active recovery consisting of cold water (5 degrees C) immersion of legs for 10 minutes either before (n = 10) or after (n = 10) cycling at 180 W for 10 minutes. In the whole group of athletes, measurements performed at rest and after training session and recovery showed no differences in MCV and MSCV values. The difference between MCV and MSCV was significant in the whole group and in the subgroup performing passive recovery, whereas the difference was not significant in the subgroups performing active recovery. This finding indicates that the use of active recovery in the top-level rugby players prevented the modifications of erythrocyte volume and shape. We outline that the values of the difference between MCV and MSCV was significantly modified in the whole group but the variations were not significant in the active recovery subgroups. The use of an index of erythrocyte shape modification (MCV - MSCV) can be very useful for evaluating sport hemolysis.

Sports anemia is a common risk for athletes. Intravasclar hemolysis is the principal source of an accelerated turnover of erythrocytes in sportsmen. The hemolysis induces some biochemical and hematological modifications; in particular, high concentrations of total and indirect (unconjugated) bilirubin could be reported in professional athletes. We recruited 24 rugby players of the Italian National Team. In these athletes we measured hematological parameters, including mean sphered cell volume (MSCV) by means of Coulter LH 750 (Beckman Coulter, Brea, CA, USA), beside biochemical parameters, including bilirubin and haptoglobin. We observed differences in the athletes' indirect bilirubin between the blood drawing performed before the start of training and competitions and the one performed at the end of the competition season. The bilirubin was increased during competition season from 7% to 329% when compared with the baseline value measured before training and competitions. MSCV, in contrast, decreased from a mean of 88.4 fL to 86 fL. The MSCV decrease in association with an indirect bilirubin increase is a specific sign of erythrocyte destruction, and specific training and competitions schemes and diet or therapy modifications should be decided according to their values. The modifications of MSCV are correlated with those of haptoglobin and hemoglobin, but not with reticulocytosis.

We assessed haematological parameters and possible modifications in elite rugby players throughout a competitive season for increasing the knowledge of physiological characteristics of these sportsmen. Blood samples were collected from the members of the Italian National rugby team at four consecutive training camps during a whole competitive season. Forty-four athletes were recruited for the first camp, 36 for the second, 30 for the third and 32 for the fourth. Due to turnover of the subjects during the season only 13 athletes could be examined at all four camps, and another six in the first three camps. Therefore, we selected the data of these 19 athletes. Iron and transferrin saturation were stable, whilst ferritin increased at the end of the season. The modifications of the soluble transferrin receptor (sTFR) were linked to those of haematocrit: sTFR increased after training and during the competition period when haemoglobin and haematocrit decreased, and decreased at the end of the season. Haemoglobin and haematocrit showed slightly higher levels during the first part of the season and decreased in the second half, when physical demand was high, as demonstrated by biochemical additional tests. Leucocytes and platelets were stable throughout the season. Haematological and iron metabolism parameters in the elite rugby players examined during a whole season fall within physiological range of values. The variability of the parameters during the season is related to training and competition workload. Reticulocytes and sTFR are the most sensitive parameters for studying the iron metabolism of the athletes.

Background: The role of measurement of reticulocytes and their parameters is growing in sports medicine. The use of reticulocyte counts in protocols for evaluating and screening for the suspected abuse of hormones that stimulate the bone marrow is an example. Reticulocytes are also important for evaluation of the performance and general health status of athletes, especially for monitoring therapies and diets. The current availability of fully automated haematological systems that can measure reticulocyte numbers and characteristics (volume, density) increases the potential use of these parameters in laboratory and sports medicine. Few studies have considered the application of these parameters in athletes and a lack of specific reference ranges means that their valid clinical use is difficult., Methods: Using a Coulter LH700 instrument, we measured reticulocyte count (Retics), mean reticulocyte volume (MRV), immature reticulocyte fraction (IRF), and mean sphered cell volume (MSCV) in 106 male professional elite athletes (football and rugby players and skiers). Reference intervals for the athletes were compared with the intervals found for a control group of 73 age-matched males., Results: We calculated the following reference intervals: 0.30-1.54% for Retics, 93.1-114.8 fL for MRV, 0.18-0.39% for IRF, and 76.8-94.5 fL for MSCV., Conclusions: No statistically significant differences were observed for Retics, MRV, IRF, and MSCV between elite athletes and controls. Significant differences were observed for haemoglobin (Hb), erythrocytes, haematocrit (Ht), and mean corpuscular volume. Moreover, no statistical differences were observed among different sports, whereas differences were remarked in football and rugby players between the samples drawn before the start of competitive season and the samples drawn during the season, demonstrating that reticulocyte counts and parameters are useful for monitoring sportsmen.

We analyzed muscle injuries collected from an Italian major-league soccer team during the period 1995-2000. We considered all the muscle accidents that had required a player to stand down for three or more days. Among the overall injuries, muscle accidents were the most frequent, representing 30% (103 cases), followed by contusions (28%), sprains (17%) and tendinopathies (9%). There was one recurrence involving the hamstring. Lack of training was one of the causes of such injuries; in fact the training/match ratio of those seasons (3.6 to 1) show that there was little time for training compared to the number of matches.

Objective: To describe and compare two ultrasonographic localization techniques for the treatment of lateral epicondylitis with extracorporeal shock wave therapy (ESWT)., Design: Forty-one subjects selected through clinical examination were randomly assigned to two groups of treatment., Interventions: Each subject received a three-session ultrasound-guided ESWT (performed weekly). Lateral tangential focusing was used in group A, whereas back tangential focusing was used for group B., Main Outcome Measures: Total Elbow Scoring System (TESS) and a visual analogue scale (VAS) were used to evaluate each subject before the treatment and at six months follow-up., Results: TESS and VAS pretreatment scores were homogeneous between the groups (p > 0.05). In both groups there was a significant (p < 0.05) increase in the TESS score and a decrease in the VAS score but there was no resolution of the pain. TESS and VAS follow-up scores were homogeneous between the two groups (p > 0.05)., Conclusions: There was no difference between the two techniques of using ESWT.

To evaluate the effects of a rehabilitation brace locked in extension for the first week on the recovery of full extension after ACL reconstruction we compared two groups of subjects who underwent ACL bone-patellar tendon-bone reconstruction. The brace was unlocked twice a day for assisted physiotherapy. In Group A, 18 male subjects wore a post-operative brace locked from 0 degrees to 90 degrees. In Group B, 18 male subjects wore the same post-op brace locked in full extension for the first week. In both groups the brace was unlocked (0 degrees -120 degrees ) at the beginning of the second postoperative week, and then removed at the beginning of the third week. All the subjects followed the same rigorous, accelerated rehabilitation protocol. Each subject was evaluated pre and post-operatively (at second, fourth and eighth week) with bubble-level heel height difference (HHD) measurements and KT 1000 arthrometric assessment at the fourth postoperative month. Preoperative bubble-level HHD measurements of the two groups were statistically similar (Group A 0.6 cm, Group B 1 cm; not significant, n.s.). At the fourth week (Group A 2.2 cm, Group B 0.6 cm) and eighth week (Group A 1.6 cm, Group B 0.1 cm) follow-ups, bubble-level HHD measurements showed that the extension of the operated knees of Group B was significantly greater than in Group A. KT 1000 arthrometric scores showed no difference between the two groups (Group A 1.8 mm, Group B 1.5; n.s.).

Objective: To evaluate the effectiveness of extracorporeal shock wave therapy (ESWT) for the treatment of painful subcalcaneal spurs and evaluate whether local steroid injections, body weight and the length of symptoms can affect the clinical results., Design: Subjects were selected through clinical examination and heel radiograms according to diagnosis of painful subcalcaneal spurs., Subjects: Sixty-four subjects were divided into two groups of treatment depending on their past history of previous local steroid injections., Interventions: Each subject received a three-session ESWT (performed weekly). A rehabilitative programme was instituted, consisting of self-assisted plantar fascia and plantar flexors stretching exercises., Main Outcome Measures: The Mayo Clinical Scoring System (MCSS) was utilized to evaluate each subject before the treatment and at two- and ten-month follow-ups. In addition, standard radiograms were done both before the treatment and at the ten-month follow-up., Results: Patients with no past treatment using steroids did not show any statistically significant improvement of the MCSS at the two-month follow-up. The statistical significance was obtained at the ten-month follow-up. Patients with past treatment using steroids did not show any statistically significant improvement of the MCSS at either follow-up. At the radiogram check, none of the subjects showed any modification of the heel spurs., Conclusions: According to the results of the present study ESWT should be considered as an effective treatment for painful subcalcaneal spurs. Previous local steroid injections may negatively affect the result of ESWT.
