Distal Interphalangeal

Background: Pain of the hand distal interphalangeal joints may result from trauma, osteoarthritis or inflammatory arthritis. When symptoms are not controlled by non-operative means, surgical arthrodesis may be performed, resulting in complete stiffness of the joint and possible weakening of grip strength. This study aims to quantify the effect of a stiff ring finger distal interphalangeal joint on overall grip strength. Methods: One hundred participants were screened to exclude upper limb pathology. A Jamar dynamometer was used to assess overall hand grip strength. A splint was used to prevent distal interphalangeal joint flexion, thus replicating a fused distal interphalangeal joint. Participants were tested with and without the splint and the results compared. The mean of three grip strength tests was taken. Results: The participants included 55 females. Mean age was 31 (18–60 years). 76 participants had a reduction in grip strength with splinting, with a significant difference seen (p < 0.05) on Wilcoxon signed rank test. The median reduction in grip strength with splinting was 1.67 kg. However only 10 participants (10%) had a grip strength loss of greater than 6.5 kg, which is the minimal clinically important difference. Conclusions: This study found a significant loss in overall hand grip strength when the ring finger distal interphalangeal joint was stiffened. However, despite this significant change, only 10 (10%) participants experienced a reduction of greater than 6.5 kg. This is the level of weakness felt to be required to reduce function. Thus our results suggest that 90% of patients with a stiff ring finger distal interphalangeal joint are unlikely to have a clinically identifiable functional reduction in grip strength as a result.

Purpose: Production of a functional grip pattern requires the concerted action of numerous structures within the hand. This study quantifies the effect of total distal interphalangeal joint (DIPJ) stiffness to grip strength. Methods: Fifty (25 men, 25 women, 100 hands) individuals with a mean age of 38 years (range: 17-69 years) were recruited. Exclusion criteria included history of previous upper limb injury, neuropathies, or systemic disease. Custom thermoplastic orthoses were used to splint participants’ DIPJ in full extension simulating stiffness. Grip strength before and after splinting was measured using a calibrated Jamar dynamometer. Data were analyzed using paired and independent sample t tests and 2 × 2 repeated-measures analysis of variance with hand dominance and configuration (splinted or unsplinted) as within-subject factors. Results: Restriction of DIPJ flexion led to a 20% decrease in grip strength ( P < .001). There was no significant difference in this decrease between dominant and non-dominant hands. Univariate analysis did not demonstrate any interaction between hand dominance and testing configuration. Post hoc analysis revealed no statistical difference in baseline grip strength between the dominant and non-dominant hands. Furthermore, men had significantly stronger grip strength than women in all configurations ( P < .001). Conclusions: Flexion at the DIPJ contributes significantly to grip strength, and stiffness at this joint greatly limits functional capabilities of the hand. This necessitates the need for targeted rehabilitation in DIPJ injuries to minimize adverse effects on grip strength.

Abstract We aimed to use hand dexterity and grip strength test as objective measures to compare the difference in surgeon fatigue associated with robotic and laparoscopic colorectal surgery. We used the Purdue Pegboard Test to assess hand dexterity and the Camry Electronic Handgrip Dynamometer to assess hand grip strength. Eighteen patients were operated on, including 10 robotic and 8 laparoscopic cases. Statistical analysis revealed no difference in dexterity or muscle fatigue after operating with the robot. In contrast, there was a significant difference in the hand grip strength of both hands after laparoscopic surgery. Our results show that the resultant fatigue after laparoscopy affects both hands of the surgeon. In contrast, there was no difference in dexterity or muscle fatigue after operating with the robot. Given the demands of complex colorectal surgeries, robotics may be a means of optimizing surgeon performance by reducing fatigue.

Introduction: Nutritional content of diet of vegetarian and non-vegetarian differs in terms of food composition and vegetarian diets are often low in protein, probably causing a difference in body composition, structure and strength characteristics. Purpose of study: To study anthropometric, body composition and hand strength differences among 641 vegetarian and 424 non-vegetarian Indian women, aged 20–60 yrs. Methods: ANOVA, t-test, multivariable stepwise regression and logistic regressions were performed to analyse association between BMI, hand grip strength and potential confounders using SPSS Version 17 for Windows. p < 0.05 referred to as statistically significant. Results: Vegetarians had less body fat than non-vegetarians. Statistically significant difference was found in their grip strength (GS) (t = 2.459, p < 0.05) and BMI (t = 2.188, p < 0.05). Height and weight were positively associated with grip strength in the vegetarian group while height and fat free mass were seen to be positively associated with grip strength in the non-vegetarian group. Grip strength was greater in non-vegetarian group and the vegetarians had lower BMI (25.33 kg/mt2 ± 4.56) than nonvegetarians (25.95 kg/mt2 ± 4.45, t-test = 2.188, p<0.05). Conclusion: Those with greater grip strength (non-vegetarian group) had greater chance of being obese than those with lower grip strength (vegetarian group). (OR = 2.609, 95% CI 1.487 - 4.577). However, lower levels of body mass indices of the vegetarian women suggest that they are healthier than non-vegetarians in terms of BMI.  DOI: http://dx.doi.org/10.3126/ajms.v4i3.8096   Asian Journal of Medical Sciences 4(2013) 43-51

Background: The ratio of the lengths of the index and the ring finger (2D:4D ratio) is generally different between men and women. This has often been used as an indicator of the levels of prenatal androgen exposure. It has hence been suggested to have a role in many gender differences including performance in sports. Men generally outperform women in most physical abilities. However, reports in various studies have been inconclusive, depending upon the physical ability tested. Hand Grip Strength (HGS) is a good measure of overall strength of an individual. Hence, we decided to determine the relationship between 2D:4D and HGS of both hands in men and women.Methods: Scanned images of both hands of young volunteers were analysed and the 2D:4D ratio calculated. HGS was measured and results correlated with 2D:4D.Results: 2D:4D ratio of men was significantly less than of women for the right (p<0.001) and the left hand (p<0.001). HGS of men was significantly greater than that of women for the right (p<0.0001) and for the left hand (p<0.0001). 2D:4D ratio in men showed a weak but significant positive correlation with HGS of right(p<0.05) and left hand(p<0.05). A weak but significant positive correlation was also seen for the left hand in females. However, 2D:4D ratios did not show any significant correlation with HGS for the right hand in women.Conclusions: We conclude that 2D:4D ratio is a measure of Hand Grip Strength in men, but is not a robust measure of HGS in women.

Background With the hypothesis that equine dorsal lamellar tissue can be desensitized by anesthesia injection into distal interphalangeal joint (DIPJ), the objective was to assess the mechanical nociceptive threshold of hoof dorsal lamellae following intra-articular (IA) administration of lidocaine into this joint. Methods The DIPJ of the forelimbs of six adult healthy horses were injected with either 5 mL of lidocaine, or 5 mL of lactated Ringer’s solution. Treatments were randomly distributed, with each forelimb undergoing a single treatment. The hooves were evaluated pre- and post-injection at pre-selected times over 4 h, using a pressure algometry model. Mechanical nociceptive thresholds (MNTs) were recorded for the sole (dorsal, palmarolateral, and palmaromedial regions), coronary band (medial, lateral, and dorsal regions), heel bulbs (medial and lateral), and dorsal lamellar region (2 cm and 4 cm distal to the coronary band). The MNT means were compared over time using the Friedman test and between treatments using the Wilcoxon signed-rank test, with values of P < 0.05 considered statistically significant. Results There were no differences between treatments for any region of the hoof during the evaluation period. However, MNT values indicating analgesia were recorded in the dorsal lamellar region in 50% of hooves following adminstration of lidocaine into the DIPJ. Conclusion The administration of 5 mL of lidocaine into the DIPJ does not significantly increase the mechanical nociceptive threshold of the equine hoof.

Little Finger

Background: Finger injuries are common in the sport of hurling. Injury to the little finger distal interphalangeal joint (DIPJ) often occurs when a high dropping ball impacts on the outstretched finger. The little finger contributes to approximately 15% of grip strength. Injury therefore results in reduced grip strength and may impair the ability of players to grip or catch a ball. Methods: Six elite hurlers with post-traumatic arthritis of their non-dominant little finger DIPJ underwent arthrodesis in 30 degrees of flexion. Kirchner wires were inserted for up to 8 weeks to achieve fusion of the joint. Patients were evaluated after recovery using a dynamometer to assess grip strength, the DASH questionnaire and a sport specific questionnaire. Results: All arthrodeses achieved bony union without complication. All patients reported a resolution of their pain and recovery in their ability to catch & retain a ball. Measurements of grip strengths were comparable between hands. DASH scores improved by up to 47 points. All scores were less than 5 at final follow-up. Conclusions: Grip strength decreases when fingers are immobilized in full extension. In sports that require catching or gripping a ball or a bat, arthrodesis of the DIP joint in flexion can improve grip strength and hand function. Fusion in 30 degrees of flexion for hurlers results in restoration of function and resolution of pain. Little finger DIPJ arthrodesis is a valid method of treating posttraumatic arthritis in ball and bat sports.
