Hamstring Injury Recurrence and Prevention: A Review

Football stands to be the most favorite sport with approximately four billion fans worldwide. Injuries in thegame can often be frustrating to the fans, athletes and the club, affecting performance and financialoperations. An avoidance curriculum to help cut down risks of such injuries seems obligatory, concerning thesocioeconomic and financial repercussions. An issue that is frequently discussed in sports medicine isHamstring Strain Injuries (HSI) that is widely seen amongst players which could prevent them from engaging inimportant games. HSI are one of the most frequently occurring injuries in sport representing approximately 12-24% of all athletic injuries. There is a high prevalence of hamstring strain injuries in many sports, includingsoccer.This review consists of summary of hamstring injury causes, prevention and current practices of treatment . Italso evaluates a contemporary method that uses whole-body vibration and its benefits to neuromuscularinvigoration and defiance exercises.

Losartan no tratamento das lesões musculares

Muscle injuries are very common in sports medicine. Frequently the muscle repair process ends in the formation of a fibrotic scar, that not only limits the complete functional recovery, but also increases the likelihood of injury recurrence. TGF-β1 is the main profibrogenic factor involved in this healing process. By blocking its activity, Losartan has proven it efficacy in reducing fibrosis and increasing regenerative and functional capacity post muscle injury. Therefore, its use should be considered as an alternative therapeutic for this kind of injuries.

Outcomes of Surgical Repair Versus Primary Tenodesis for Proximal Rectus Femoris Avulsion Injuries in Professional Athletes

Background: Surgical repair of proximal rectus femoris avulsion injuries is associated with prolonged periods of rehabilitation and highly variable risk of injury recurrence. Surgical tenodesis of these injuries is often reserved for recurrent injuries or revision surgery. To our knowledge, the outcomes of proximal rectus femoris avulsion injuries treated with surgical repair versus primary tenodesis have not been previously reported. Hypothesis: Primary tenodesis of proximal rectus femoris avulsion injuries is associated with reduced risk of injury recurrence as compared with surgical repair. Study Design: Cohort study; Level of evidence, 3. Methods: This study included 25 patients (22 male and 3 female) who underwent surgical repair versus 30 patients (26 male and 4 female) who received primary tenodesis for proximal rectus femoris avulsion injuries. Predefined outcomes were recorded at regular intervals after surgery. Mean follow-up time was 27.9 months (range, 24.0-31.7 months) from date of surgery. Results: All patients returned to their preinjury levels of sporting activity. Primary tenodesis was associated with earlier return to preinjury level of sporting function as compared with surgical repair (mean ± SD, 12.4 ± 1.6 vs 15.8 ± 2.2 weeks; P < .001) and reduced risk of recurrence (0% vs 16%; P < .001). At 1-year follow-up, there was no difference in surgical repair versus primary tenodesis relating to patient satisfaction scores (12 very satisfied and 13 satisfied vs 16 very satisfied and 14 satisfied; P = .70), isometric quadriceps strength (95.6% ± 2.8% vs 95.2% ± 6.3%; P = .31), Tegner scores (median [interquartile range], 9 [8-9] vs 9 [8-9]; P = .54), and lower extremity functional scores (73 [72-76] vs 74 [72-75]; P = .41). High patient satisfaction, quadriceps muscle strength, and functional outcome scores were maintained and remained comparable between treatment groups at 2-year follow-up. Conclusion: Primary tenodesis was associated with reduced time for return to preinjury level of sporting function and decreased risk of injury recurrence when compared with surgical repair for proximal rectus femoris avulsion injuries. There were no differences in patient satisfaction, functional outcome scores, and quadriceps muscle strength between the treatment groups at 1- and 2-year follow-up.

Hand and Wrist Injuries in Men’s and Women’s National Collegiate Athletic Association Basketball

Background: Hand and wrist injuries (HWIs) are common in National Collegiate Athletic Association (NCAA) basketball players and can negatively affect performance. There is limited literature available on this topic. Purpose: To open a discussion on prevention strategies and encourage future research on HWIs in basketball athletes. Study Design: Descriptive epidemiology study. Methods: HWIs sustained by male and female NCAA basketball players during the 2009-2010 through 2013-2014 academic years and reported to the NCAA Injury Surveillance Program (NCAA-ISP) database were utilized to characterize the epidemiology thereof. Rates and distributions of HWIs were identified within the context of mechanism of injury, injury recurrence, and time lost from sport. Results: Over the 5-year period, 81 HWIs in women and 171 HWIs in men were identified through the NCAA-ISP database. These were used to estimate 3515 HWIs nationally in women’s basketball athletes and 7574 HWIs nationally in men’s basketball athletes. The rate of HWIs in women was 4.20 per 10,000 athlete-exposures (AEs) and in men was 7.76 per 10,000 AEs, making men 1.85 times more likely to sustain HWIs compared with women. In men, HWIs were 3.31 times more likely to occur in competition compared with practice, while in women, HWIs were 2.40 times more likely to occur in competition than in practice. Based on position, guards, both men and women, were the most likely to suffer HWIs. Conclusion: HWIs were common in collegiate basketball players. Most injuries were new, and the majority of players were restricted from participation for less than 24 hours. Men were more likely to be injured compared with women, and injuries were most common in the setting of competition for both sexes. The majority of injuries was considered minor and did not extensively limit participation; however, prevention and detection remain important for optimal performance.

Fifteen-week window for recurrent muscle strains in football: a prospective cohort of 3600 muscle strains over 23 years in professional Australian rules football

ObjectivesTo determine the rates of muscle strain injury recurrence over time after return to play in Australian football and to quantify risk factors.MethodsWe analysed Australian Football League player data from 1992 to 2014 for rates of the four major muscle strain injury types (hamstring, quadriceps, calf and groin) diagnosed by team health professionals. Covariates for analysis were: recent history (≤8 weeks) of each of the four muscle strains; non-recent history (>8 weeks) of each; history of hip, knee anterior cruciate ligament, knee cartilage, ankle sprain, concussion or lumbar injury; age; indigenous race; match level and whether a substitute rule was in place.Results3647 (1932 hamstring, 418 quadriceps, 458 calf and 839 groin) muscle strain injuries occurred in 272 759 player matches. For all muscle strains combined, the risk of injury recurrence gradually reduced, with recurrence risks of 9% (hamstring), 5% (quadriceps), 2% (calf) and 6% (groin) in the first match back and remaining elevated for 15 weeks after return to play. The strongest risk factor for each muscle injury type was a recent history of the same injury (hamstring: adjusted OR 13.1, 95% CI 11.5 to 14.9; calf OR 13.3, 95% CI 9.6 to 18.4; quadriceps: OR 25.2, 95% CI 18.8 to 33.8; groin OR 20.6, 95% CI 17.0 to 25.0), followed by non-recent history of the same injury (hamstring: adjusted OR 3.5, 95% CI 3.2 to 3.9; calf OR 4.4, 95% CI 3.6 to 5.4; quadriceps OR 5.2, 95% CI 4.2 to 6.4; groin OR 3.5, 95% CI 3.0 to 4.0). Age was an independent risk factor for calf muscle strains (adjusted OR 1.6, 95% CI 1.3 to 2.0). Recent hamstring injury increased the risk of subsequent quadriceps (adjusted OR 1.8, 95% CI 1.2 to 2.7) and calf strains (OR 1.8, 95% CI 1.2 to 2.6). During the ‘substitute rule’ era (2011–2014), hamstring (adjusted OR 0.76, 95% CI 0.67 to 0.86), groin (OR 0.78, 95% CI 0.65 to 0.93) and quadriceps (OR 0.70, 95% CI 0.53 to 0.92) strains were less likely than outside of that era but calf (OR 1.6, 95% CI 1.3 to 1.9) strains were more likely than before the substitute rule era.ConclusionRecent injury is the greatest risk factor for the four major muscle strains, with increased risk persisting for 15 weeks after return to play.

Epidemiology of Lumbar Spine Injuries in Men’s and Women’s National Collegiate Athletic Association Basketball Athletes

Background: Lumbar spine injuries (LSIs) are common in both men’s and women’s National Collegiate Athletic Association (NCAA) basketball players and can frequently lead to reinjuries and persistent pain. Purpose: To describe the epidemiology of an LSI in collegiate men’s and women’s basketball during the 2009-2010 through 2013-2014 academic years. Study Design: Descriptive epidemiology study. Methods: The incidence and characteristics of LSIs were identified utilizing the NCAA Injury Surveillance Program (ISP). Rates of injury were calculated as the number of injuries divided by the total number of athlete-exposures (AEs). AEs were defined as any student participation in 1 NCAA-sanctioned practice or competition. Incidence rate ratios (IRRs) were then calculated to compare the rates of injury between season, event type, mechanism, injury recurrence, and time lost from sport. Results: The NCAA ISP reported 124 LSIs from an average of 28 and 29 men’s and women’s teams, respectively. These were used via validated weighting methodology to estimate a total of 5197 LSIs nationally. The rate of LSIs in women was 2.16 per 10,000 AEs, while men suffered LSIs at a rate of 3.47 per 10,000 AEs. Men were 1.61 times more likely to suffer an LSI compared with women. In men, an LSI was 3.48 times more likely to occur in competition when compared with practice, while in women, an LSI was 1.36 times more likely to occur in competition than in practice. Women suffered the highest LSI rate during the postseason, while the highest rate in men was during the regular season. The majority of both female (58.9%; n = 1004) and male (73.1%; n = 2353) athletes returned to play within 24 hours of injury. Conclusion: To date, this is the largest study to characterize LSIs in NCAA basketball and provides needed information on the prevalence and timing of these injuries. The majority of injuries in both sexes were new, and most athletes returned to play in less than 24 hours. Injury rates were highest during competition in both sexes.
