The palmaris longus is harvested as a tendon graft in various surgical procedures. Several tests are used to assess the presence of palmaris longus tendon. In the present study, we attempted to assess the interobserver and intraobserver reliability of five of the most famous methods and also the examination of fifth superficial flexor function. Two observers, who had been trained on the tests and had practiced them, examined 105 volunteers on two separate occasions and in 1-month interval the results were recorded. The reliability of each method was assessed with Kappa measurement. Kappa ranged from 0.541 (moderate reliability) to 0.813 (almost complete agreement) for palmaris. The highest interobserver and intraobserver reliability and also the best agreement with other tests were of Schaeffer. The lowest kappa was for Thompson and the others have good to excellent reliability. Kappa for interobserver and intraobserver reliability for the fifth flexor were 0.415 and 0.500 (moderate reliability), respectively. The tests that were assessed have good reliability except for Thompson that has a moderate one. It seems that the standard test (Schaeffer) is the best method for the assessment of the absence or presence of palmaris longus. The method used for the evaluation of fifth superficial flexor variations assessment has a moderate interobserver and intraobserver reliability.

Background:Ulnar sided wrist pain is one of the most common complications of distal radius fractures. The simplest method for decreasing pain for this affliction is corticosteroid injection. The present study was designed to assess the effect of corticosteroid injection in the prevention of ulnar sided wrist pain.Materials and Methods:In this clinical trial patients with distal radius fractures scheduled for closed reduction and percutaneous pin fixation were divided into control and corticosteroid groups. In the corticosteroid group, the patient received a single betamethasone injection in the dorsoulnar side of the wrist before reduction, while the control group received placebo. The patients were to be followed for at least 6 months.Results:82 patients were followed for 6 months. At the end of the 3 months followup the difference between the two groups about the number of individuals without ulnar sided wrist pain was statistically significant (P = 0.038), so that less patients in the control group were painless, while this was not the case in the 6 months followup (P = 0.507), but in the both time frames the mean grip power, visual analog pain score and the disabilities of the arm, shoulder and hand (DASH) score showed statistically significant difference between the two groups, so that the corticosteroid groups demonstrated greater power grip and less scores in pain and DASH (P < 0.05).Conclusion:Based on the findings of the present study it seems that prophylactic corticosteroid injection will be associated with a decrease in the severity of wrist pain in patients with acute distal radius fractures. With regard to the decrease in the number of painless individuals, it seems that the decrease is not persistent. Overall the need for a study with longer followup is obvious.

Carpal tunnel syndrome (CTS) is defined as a compressing median mononeuropathy. CTS is one of the major costly debilitating diseases of the hand. Although CTS is a relatively recent concept in current medicine, some evidences show that medieval physicians in Persian medicine (PM) such as Avicenna were familiar with it. The PM textbook written by Avicenna, the Canon of Medicine, defines the anatomy of carpal tunnel and median nerve, as well as mononeuropathy; it also offers suggestions for the prevention and treatment of carpal tunnel syndrome (called as Vaja al-asab and Khadar) in the chapter of nerve diseases. The book describes not only symptoms including pain, paresthesia, hypoesthesia, tingling, and numbness, but also its etiology such as nerve compression (entrapment neuropathy); nonphysical reasons such as disturbed balance among the four body humors; alteration in the nerve's temperament (Mizaj) that prevents the transmission of nerve impulses; and the others such as nutrition, mental condition, sleep, weather condition, body movements, and proper disposal of body waste. Furthermore, the book suggests a lifestyle modification method based on six factors and 10 prescriptions composed with 85 natural products that are not actively used for CTS treatment in modern times. The medicinal suggestions for CTS in the Canon of Medicine will be good candidates for discovering new treatments besides providing historical significance to the various insights considered 1000 years ago.

This study compared the therapeutic effect of flax seed oil topical gel and hand splint in the treatment of carpal tunnel syndrome. This study was a randomized clinical trial. Forty-nine patients, 96 hands, with mild to moderate idiopathic carpal tunnel syndrome were divided into 2 groups randomly. One group was treated by topical gel and the other group by hand splint. Intensity of symptoms and function before and after intervention was measured via Boston Carpal Tunnel Questionnaire. After intervention, the ANCOVA showed a significant difference between the symptom and function scores of the 2 groups. In both cases, recovery was higher in the gel group (P < .001). The topical use of flax seed oil gel is more effective in the improvement of symptoms and function of patients with mild to moderate carpal tunnel syndrome as compared with hand splint, and it can be introduced as an effective treatment.

Background:The optimal nonoperative management for subacromial impingement syndrome (SIS) is unclear. This study evaluated the efficacy of subacromial corticosteroid, hyaluronic acid injection and physiotherapy in patients with SIS to determine which treatment is most effective. Methods:SIS patients treated with either physiotherapy or subacromial injection of triamcinolone (40 mg), or subacromial hyaluronic acid injection were included in this retrospective study. The outcome measures were evaluated 3 and 6 mo after the intervention and included pain evaluated by a visual analog scale (VAS) and limb function assessed by the Disabilities of the Arm, Shoulder, and Hand (DASH) and American Shoulder and Elbow Surgeons (ASES) questionnaires. Results:Eighty-eight patients with SIS were included. Treatment was done with corticosteroid injection in 31 patients, hyaluronic acid injection in 30 patients, and physiotherapy in 27 patients. The mean improvement of VAS, DASH, and ASES scores of the corticosteroid group was significantly higher when compared with the physiotherapy group at 3 mo (P = 0.035, P < 0.001, and P < 0.001, respectively) and 6 mo (P = 0.036, P < 0.001, and P < 0.001, respectively), also in comparison with the hyaluronic acid group at 3 mo (P = 0.038, P < 0.001, and P = 0.002, respectively) and 6 mo (P = 0.044, P < 0.001, P < 0.001, respectively). The mean improvement of DASH and ASES scores, but not VAS, was significantly higher in the hyaluronic acid group compared to the physiotherapy group at 3 mo (P = 0.022, P = 0.034, and P = 0.55, respectively) and 6 mo (P = 0.46, P = 0.039, and P = 0.51, respectively). Conclusions:Subacromial corticosteroid injection is more effective than physiotherapy and hyaluronic acid injection in treating SIS symptoms.

Background: Given the increasing use of waterpipe tobacco smoking in the world and its unknown effects on bone healing, this study investigated the repairing of femoral bone fractures in rats exposed to waterpipe tobacco smoking (WTS).Main Methods: This study involved 40 male Wistar rats that were divided into two groups, including the femoral fracture (Fx) and the Fx + WTS groups. Each group was divided into two subgroups that were evaluated for bone healing 28 and 42 days after femoral fracture. After fixing the fractured femur, the healing process was evaluated by radiography, pathological indicators, and a measurement of the blood levels of vascular endothelial growth factor (VEGF), parathyroid hormone (PTH), Ca ++, transforming growth factor-beta (TGF-β), and insulin-like growth factor 1 (IGF-1). Additionally, the density of VEGF and CD34 in fracture tissue was investigated by immunohistochemistry.Key Findings: Radiographic findings showed that factors related to the earlier stages of bone healing had higher scores in the Fx + WTS28 and 42 subgroups in comparison to the Fx groups. The density of VEGF and CD34 showed that the angiogenesis processes were different in the bone fracture area and callus tissue in the Fx +WTS subgroups. The serum levels of VEGF, TGF-β, and IGF-1 were significantly lower in the Fx +WTS42 group, and PTH in the Fx +WTS28 group was higher than that in the other groups.Significance: The findings showed the disturbance and delay in the femoral fracture union in rats exposed to hookah smoke. This is partly due to the reduction of molecular stimuli of bone synthesis and the attenuation of quantitative angiogenesis.

Background:Associated injuries in tibial shaft fractures are not investigated often, and their impact on patient outcome is not clear. In this study, associated knee injuries in tibial shaft fractures were arthroscopically investigated, and their impact on the outcomes of patients were evaluated. Methods:In a prospective study, 57 patients with closed tibial shaft fractures and without concomitant fibular fractures were included. Motorvehicle accident was the most frequent mechanism of the injury. The fractures were treated with reamed and locked titanium intramedullary tibial nailing. The functional outcome was evaluated using the International Knee Documentation Committee score and compared between the patients with and without an ipsilateral associated injury. Results:The mean age of the patients was 33.2 ± 13.2 years. The mean follow-up duration was 10.2 ± 3.1 mo. In 35 patients (61.4%), at least one associated knee injury was detected. Chondral damage was the most frequent arthroscopic finding (n = 23, 40.4%). The anterior cruciate ligament (ACL) injury was the second most frequent injury (n = 7, 12.3%). No intervention was performed for chondral lesions and ACL tears. Meniscal injuries were detected in three (5.3%) patients only. The mean International Knee Documentation Committee score was 95.9 ± 2.2 in patients with and 96.2 ± 2.1 in patients without an arthroscopic finding (P = 0.38). The severity of comminution was not correlated with the incidence of arthroscopic findings (r = 0.089, P = 0.45). Conclusions:Ipsilateral injuries are frequent in tibial shaft fractures. However, they do not seem to affect the functional outcome of patients, at least in short-term follow-up.
