Statistical Effects

The study aims to find out the incidence of the absence of palmaris longus tendon and to study the effects of the case on handgrip strength of athletes. We studied whether 190 athletes (male n= 80, mean age: 18.9� 2.2; female n= 110, mean age: 18.5� 1.2) included in our study had palmaris longus tendon or not. Then, the handgrip strength values of the athletes were obtained by using a Jamar dynamometer, according to the recommendations of the American Association of Hand Therapists. Total number of participants having no palmaris longus tendon was 59 (31.05%) and it was observed that 37(19.47%) of these individuals didn�t have the tendon in both hands. The number of participants with unilateral tendon absence was 22 (11.5%). The tendon was absent in right hand of 10 individuals (5.26%) and in left hand of 12 individuals (6.31%). After controlling age, height, body weight and body mass index variables of the groups, it was observed that the presence or the absence of palmaris longus tendon in both hands of male athletes didn�t cause any statistical effects on handgrip strength of the athletes. However, left handgrip strength of female athletes with palmaris longus tendon in left hand was found to be higher than left handgrip strength of female athletes with no palmaris longus tendon (p[.01). According to the findings of the study, we might state that the presence or the absence of palmaris longus tendon does not cause a significant effect on handgrip strength of both hands of male athletes (p].05) and that its presence causes a significant effect on left handgrip strength of female athletes (p[.01).

ObjectivesTo compare the mortality of Japanese athletes in the 1964 Tokyo Olympic Games with that of the Japanese population, and to elucidate factors associated with their mortality.MethodsWe obtained from the Japan Sport Association study subjects’ biographical information, information on lifestyles and medical data. Missing data were obtained from online databases. Standardised mortality ratio (SMR) was calculated to compare athletes’ mortality with the Japanese population. Cox proportional hazards model was applied to estimate the HR for each category of body mass index (BMI), smoking history and handgrip strength. This analysis was limited to male athletes due to the small number of female athletes.ResultsAmong 342 (283 men, 59 women) athletes, deaths were confirmed for 70 (64 men, 6 women) athletes between September 1964 and December 2017. Total person years was 15 974.8, and the SMR was 0.64 (95% CI 0.50 to 0.81). Multivariate analysis performed on 181 male athletes. Mortality was significantly higher for BMI≥25 kg/m2 than for 21–23 kg/m2 (HR: 3.03, 95% CI 1.01 to 9.07). We found no statistically significant associations between smoking history and mortality; the HR (95% CI) for occasional and daily smokers were 0.82 (0.26 to 2.57) and 1.30 (0.55 to 3.03) compared with never smokers. We also found no statistically significant associations between handgrip strength and mortality (P for trend: 0.51).ConclusionJapanese athletes in the 1964 Tokyo Olympic Games lived longer than the Japanese population. BMI≥25 kg/m2 was associated with higher mortality, but smoking history and handgrip strength were not associated with mortality.

We present a modification of Bunnell’s technique for harvest of the palmaris longus tendon. Using a 0.5 cm distal incision and a proximal stab incision the tendon is harvested with minimal scarring and, in our experience of over 30 cases, no morbidity.

Palmaris Longus Tendon

Background: A rare and disastrous complication of harvesting a tendon graft is the misidentification of the median nerve for the palmaris longus. Methods: The authors report a referred case in which the median nerve was harvested as a free tendon graft. Results: Few reports of this complication are found in the literature despite the frequency of palmaris longus tendon grafting and the proximity of the palmaris tendon to the median nerve. Given the obvious medicolegal implications, the true incidence of this complication is difficult to assess. Discussion: Safe harvesting of the palmaris longus mandates a thorough understanding of the relevant anatomy, in particular the proper differentiation between nerve and tendon and recognition of when the palmaris longus tendon is absent. Techniques to facilitate proper identification of the palmaris longus are outlined.
