Reconstructive Plastic

The palmaris longus tendon is the most frequently harvested tendon for reconstructive plastic and hand surgical procedures. A question patients often ask is whether loss of the palmaris longus will result in any functional deficit. In order to answer this question, the presence or absence of the palmaris longus muscle was clinically determined in 418 normal Asian subjects. All subjects also had their grip and pinch strengths measured. No statistically significant difference was seen in the grip or pinch strength measurements between subjects who had a palmaris longus tendon and those who did not. This study demonstrates that absence of the palmaris longus is not associated with a decrease of grip or pinch strength.

The Individual

Background: Palmaris longus tendon is often used as a donor tendon by surgeons in tendon grafts. It is one of the flexor muscles of the forearm and documented well for its variations in both morphology and number of tendons. Prevalence of absence of this muscle varies among the individuals of same population and individuals of various ethnic groups. The aim of this study was to assess the existence of Palmaris longus muscle within a group of students and its association with side of the limb and gender of the individual. Methods: Three hundred medical students of 150 males and 150 females with age group of 18–21 years were clinically assessed. The standard Schaffer’s test was used for the assessment of PL tendon. If the tendon was not found in this test, the confirmation was done by other four tests. Results: Results of this study shows that an overall absence of palmaris longus muscle in both sexes was found to be 32%, out of which 21% absence was found in males and 43% absence found in females. Among the males, the unilateral agenesis was seen in 16% and bilateral agenesis in 4% and in females the unilateral agenesis was seen in 29% and bilateral agenesis seen in 14%. Conclusions: To conclude; in the present study, prevalence of Palmaris longus muscle agenesis was found to be more in female subjects on their left side. Surgeons who plan for tendon reconstructive procedures should know variations of Palmaris longus muscle and its clinical assessment.

INTRODUCTION: The effect of the absence or presence of the Palmaris longus tendon on pinch and grip strength was investigated in this study. Similarly, the effect of the presence or absence of the fifth superficial flexor digitorum on grip strength in the hand was studied. The aim of the present study was to assess the combined effect of these anatomical variations on pinch and grip strength. MATERIALS AND METHODS: In this cross-sectional study, 523 volunteers and their 1046 hands were enrolled. Each hand was assessed for the presence or absence of the Palmaris longus tendon and for variations in the fifth superficial flexor digitorum function. Then the grip and pinch power of the hands were measured with the Jammar Dynamometer. RESULTS: The presence or absence of Palmaris longus had no effect on grip strength in the individuals studied. Likewise, variations in fifth superficial flexor digitorum function had no effect on grip and pinch strengths. But the results of statistical testing showed the effect of the presence of Palmaris longus on pinch strength (25.38 lbs in hands with Palmaris present vs 24.43 lbs in hands without Palmaris). Pinch and grip power was higher in men than in women and in the right hand than in the left. CONCLUSION: Based on the findings of the present study, it seems that absence of the Palmaris longus tendon is associated with a reduction in pinch strength but has no effect on grip strength, and the variations in the fifth superficial flexor digitorum (flexor digitorum superficialis, or FDS) have no effect on pinch and grip strengths.

Background: Aim: To assess the palmaris longus muscle.Methods:40 formalin fixed cadavers of both genders were included. Routine dissection of the upper limb was carried following the Cunnigham’s Manual of Practical Anatomy. During the dissection of the anterior compartment of forearm, the Palmaris longus muscle was identified & carefully dissected.Results:Out of 40 cadavers, 22 were of males and 18 were of females. Morphology of Palmaris longus found to be normal in 18, agenesis in 6, fusiform in 4, hybrid in 6, bifurcated tendon in 5 and fleshy in 1 case. A significant difference was observed (P< 0.05).Conclusions:Surgeon must be aware of the variations of palmaris longus muscle. Morphology of Palmaris longus found to be normal, agenesis, fusiform, hybrid, bifurcated tendon and fleshy.

Palmaris Longus (PL) is a muscle of the forearm, i.e., not functionally necessary and does not exist in all people. It is a choice for tendon graft and investigating its prevalence is of clinical importance. During April-October 2009, 102 cadavers (78 males, 24 females) were bilaterally necropsied for PL exploration in Zanjan City, Iran. PL Absence (PLA) was observed in 37 (36.3%) cases (28 males, 9 females). PLA prevalence was similar in men (36%) and women (37.5%). Of PLA cases, 19 (51%) were unilateral (14 males, 5 females), and 18 (49%) were bilateral (14 males, 4 females). In conclusion, PLA prevalence of 36.3% in our population was similar to other studies conducted in Iran. We found no gender difference in PLA prevalence and its patterns. Due to geographical variability in PLA rate, future regional and national studies with more magnificent sample sizes are recommended to determine the prevalence and gender-specific patterns of PLA.
