    Do you work out for health benefits and feel you are exercising more than enough? You might be among the many Canadians who overrate how hard they work out or underestimate what moderate intensity exercise means, according to a recent study out of York University’s Faculty of Health.

  • Risk factors identified for little league shoulder

    Source: Medical News Today


    As cases of Little League Shoulder (LLS) occur more frequently, the need for additional information about the causes and outcomes of the condition has become clear. Researchers presenting at the American Orthopaedic Society for Sports Medicine’s (AOSSM) Annual Meeting shared new data identifying associated risk factors, common treatment options and return to play.

  • NFL players return to the game after stabilizing shoulder surgery

    Shoulder instability is a common injury in football players but the rate of return to play has not been regularly determined following surgery. A new study, discussed at the American Orthopaedic Society for Sports Medicine’s (AOSSM) Annual Meeting, details that return rates for NFL players is approximately 90 percent no matter what the stabilization procedure (open vs. arthroscopic).

  • Anatomic features not tied to pain in rotator cuff tears

    Anatomic features associated with the severity of atraumatic rotator cuff tears are not associated with pain level, according to a study published in the May 21 issue of The Journal of Bone & Joint Surgery.

  • Extended capsular release unnecessary for shoulder stiffness in arthroscopic surgery

    Although arthroscopic capsular release is a known treatment for shoulder stiffness, posterior extended capsular release might not be necessary in arthroscopic surgery, according to study results.


    Researchers enrolled 75 patients who underwent arthroscopic capsular release for shoulder stiffness. The patients were randomly assigned to one of two groups: those in whom capsular release, including release of the rotator interval and anterior and inferior capsule, was performed (n = 37), and those in whom capsular release was extended to the posterior capsule (n = 38).


    The researchers used American Shoulder and Elbow Surgeons scores, Simple Shoulder Test, VAS pain scores and range of motion (ROM) for evaluation before surgery, at 3, 6 and 12 months postoperatively, and at the last follow-up. Mean follow-up was 18.4 months.


    ROM increased significantly among both groups at the last follow-up compared with preoperative scores (P < .05). However, there were no statistical differences between the two groups in American Shoulder and Elbow Surgeons scores, Simple Shoulder Test and VAS pain scores at the last follow-up (P > .05), according to the researchers.

  • Shoulder activity not associated with severity of atraumatic rotator cuff tear

    Source: Healio


    Among patients with atraumatic rotator cuff tears, shoulder activity was not associated with severity of the tear, but was affected by patients’ age, sex and occupation, according to study results.


    Researchers prospectively enrolled patients with an atraumatic rotator cuff tear on MRI in the Multicenter Orthopaedic Outcomes Network shoulder study of nonoperative treatment. Patients were asked to complete a previously validated shoulder activity scale; 434 patients completed the scale and were included in the analysis. Mean patient age was 62.7 years.


    The researchers performed a regression analysis to assess the association of shoulder activity level to rotator cuff tear characteristics, including tendon involvement and traction, as well as patient factors such as age, sex, smoking and occupation.


    Shoulder activity was not associated with severity of the rotator cuff tear, according to the researchers. However, shoulder activity was negatively associated with age and female sex. According to the regression model, 69-year-old patients with rotator cuff tears were 1.5 points less active on the 20-point scale vs. identical 56-year-old patients; female patients were 1.6 points less active vs. similar male patients. Occupation was also a significant predictor of shoulder activity level, with unemployed patients predicted to be 4.8 points less active compared with employed patients.

  • Elbow surgery risk may be increased by early entry to Major League Baseball

    Source: Medical News Today


    The common elbow surgery made famous by Major League Baseball (MLB) pitcher, Tommy John, definitely does its job to return pitchers to the mound, but risks for having the surgery may be able to be recognized earlier in a player’s career, say researchers presenting their work at the American Orthopaedic Society for Sports Medicine’s (AOSSM) Annual Meeting. The study was the largest cohort of MLB pitchers, to date, that have undergone UCL reconstruction.

  • Prior TKR or revision THR causes increased periprosthetic fractures

    Source: Healio


    Periprosthetic fractures are especially common in patients with prior total knee replacement or revision total hip replacement a decade after primary total hip replacement, according to study results.


    Researchers identified 58,521 Medicare beneficiaries who had elective primary total hip replacement (THR) for non-fracture diagnoses between July 1995 and June 1996 and followed them using Medicare Part A claims data through 2008. Using ICD-9 codes, researchers identified periprosthetic femoral fractures occurring from 2006 to 2008. The incidence density method was used to calculate the annual incidence of periprosthetic femoral fractures, and Cox proportional hazards models were used to identify risk factors for periprosthetic fracture. The risk of hospitalization during the subsequent year was also calculated.


    Overall, 55% of patients who had elective primary THR between July 1995 and June 1996 survived until January 2006, with 0.7% of these patients developing a periprosthetic femoral fracture between 2006 and 2008. The researchers found an annual incidence of periprosthetic fractures of 26 per 10,000 person-years among these individuals.


    According to Cox proportional hazards models, patients had a greater risk of periprosthetic fracture after having a total knee replacement or a revision total hip replacement between the primary THR and 2006. The researchers found a three-fold higher risk of hospitalization in the subsequent year among THR patients who sustained periprosthetic femoral fracture compared with patients without fractures.


    “These data will help clinicians as they portray to patients and their families the long-term concerns associated with living with a hip implant,” the researchers wrote. “The message is that periprosthetic fractures are relatively rare, though more frequent in patients with multiple implants. Further, these fractures are typically associated with the need for considerable subsequent medical care, as they are accompanied by a much greater risk hospitalization in the subsequent year than experienced by THR recipients who did not have hip fracture.”

  • Obesity may be driving increasing need for knee and hip replacements in steadily younger patients

    The impact of being overweight has far reaching health implications — implications that may be taking a toll at an earlier age.


    In a new study, researchers found that packing on the pounds may be setting the stage for total knee or hip replacement at increasingly younger ages.


    Further, the scientists found that being overweight or obese had a greater impact on the knee than the hip.
