[Evaluation of correlation between Q-angle and anterior knee pain]

Knee pain is one of common cause that patients refer to orthopedic clinics and has several reasons. One group is reversible and other is irreversible. Excessive Q-angle composes of 10% causes of knee pain reasons and is recovered [90%] by physical therapy. This study was conducted for evaluation of correlation of knee pain with excessive Q-angle and comparing both sexes and ages groups. 100 patients [50 men and 50 women] in a simple convenience study were enrolled in this research. Q-angle and pain scale [VSA] were measured and then Q-angle deviation in both sexes and ages groups analyzed using ANOVA, t-test. Spearman test with SPSS17 software. The correlation between severity of knee pain and Q-angle in general population and in both sex was significant using of Spearman's test. There was no significant correlation between different ages and Q-angle. There was significant relationship between Q-angle in men and women [P<0.05]. 10% of men, 18% of women and 14% of general population refered to orthopedic clinic had Q-angle greater than normal range. Higher level of Q-angle in females might be related to anatomical differences and high level of estrogen, multiparity, malnutrition, genetical differences and excessive activity, in females

relationship between normal intercondylar and intermaleolar distances and epidemiological factors in children 3-16 years of age

In evaluation of genu varum and genu valgum which are common in growth period of children, tibiofemoral [TF], intercondylar [1C] and intermaleolar [IM] distances are commonly measured. Normally, the legs of most newborns are slightly curved or have moderate curves medially when they are in standing position. During their growth, the extension of the lower limb changes. The aim of this study was to determine the relationship between normal intercondylar and intermaleoar distances and physiolgical factors among these subject groups. In this cross-sectional study a group of 850 children [452 females, 398 males] aged between 3 to 16 years old were studied. The samples were collected randomly from kindergartens, preschool care centers and schools in all 4 districts of Ahvaz, plus a few patients in Shafa hospital. The intercondylar and intermaleolar distance were examined in standing position, while the knee and hip joints were fully extended and the two medial maleolus or two medial condye of knees were in contact. In this study, descriptive statistics as well as t- and ANOVA tests were used for comparison. Pearson correlation for the survey were used data analysis by SPSS version 15. The mean of intercondylar distance among studied groups was 1.65 +/- 0.86: 1.5 in boys and 1.71 cm in girls respectively. The mean of intermaleolar distances was 2.31cm in males 2.05cm and in females 2.53 cm, the difference was significant [P<0.05]. There was a direct ralationship between intermaleolar distance and weight, height and length of leg, but relationship between Intercondylar distance and these factors is in reverse order

Survey of relationship between type of delivery and tibiofemoral angle, inter condylar and intermaleolar distances at 3-16 years old in Ahvaz

some studies shown that position of fetus in uterus could be some lower limb deformities. Up to now, no research has been done about relationship between type of delivery and tibiofemoral developing. We were investigated to consider of this relationship in people between 3-16 years old in Ahvaz city. This cross-sectional study was carried out on 853 people [455 girls and 398 boys]. Tibiofemoral [TF] angle, Intercondylar and intermalleolar distances were measured in standing position with knees and hip in full extension. Information about a kind of delivery [caesarian or vaginal] were taken by questionnaires in which was completed by their parents. TF angle in cesarean sections was more than in vaginal deliveries and the difference was statistically significant [p=0.02]. Intercondylar and intermalleolar distances in cesarean sections were more than in vaginal deliveries but the differences were not statistically significant. There is significant relationship between tibiofemoral and type of delivery, but for the future work need to evaluate the effect of fetal position and adaptathions [mechanism of laber] in the development of tibiofemoral angle after birth

[Epidemiological review of upper and lower extremity joints dislocations among visiting patients in Imam Khomeini Hospital Ahvaz in 2005]

The aim of this study was to review of incidental pattern of upper and lower extremity joints dislocations among patients in Imam Khomeini Hospital, Ahvaz in 2005 for the first time which is the referral university hospital in the province of Khuzestan, Iran. This was a retrospective and descriptive study among in and out patients in orthopedic surgery department of Imani Khomeini hospital during 2005 on the basis of a total amount of 64000 cases [62000 outpatient and 2000 admitted cases].The study was done for the presence of any dislocation, involved limb, age, sex, side of the involvement, accompanying injuries, mechanism of injury, open or closed dislocation. There was a total amount of 128 dislocations [Men=85% Women =l5%] 52.3% in the right side and 47, 7% in the left side 64% of dislocations accompanied by a fracture and 30,5% needed hospital admission. In all cases there was only one joint involvement and the most common age of joint dislocation was in the third decade of life more than 77% of dislocation occurred among patients between 10-40 years old. Neurological damage was found in only one case and there was no vascular injury. Incidence of closed dislocation was 98.4% and the most common mechanism of injury as accident [32.8%].Joint dislocations were more common in the upper extremity [73.4%] in shoulder [21.1%] and in hand Mp joint [16.4%] In the lower extremity hip dislocation was more common [81.8%].Gallezia fracture dislocation was the most common form of a fracture dislocation combination [20.3%]. Dislocation was more common in the male gender, upper extremity, right side and third decade of life. Accident was the most common mechanism of joint dislocation. Shoulder was the most common dislocated joint in the upper extremity and hip was so in the lower extremity. Most cases required short term admission in the Emergency Orthopedic Department and only one case of ulnar nerve injury was discovered among joint dislocation cases.

Hydatidosis of tibia

A 71 year old female from a village was admitted to Ahwaz Imam Khomeini hospital in southwestern part 7 years ago with pain and swelling at the upper and middle third of right tibia. Operation was performed and permanent sinus secretion of the midportion occurred. After 7 years the patient returned to hospital recently with warmness, swelling and edema and sinus secretion in middle and upper of right leg. Radiological examination revealed osteolytic metaphyseal and diaplyseal lesion with honey combs appearance transitional zone was narrow without reactive bone and incomplete fractures were also noted. Abdominal sonography was normal. Wound discharge culture indicated Klebsiella, Proteus and E. coli. After antibiotic therapy the patient was put under general anesthesia and complete excision of middle part of tibia from proximal metaphysic to distal metaphysis was performed. During the operation laminated layers and daughter cysts of hydatid cysts were seen. The lesion was washed with 0.5% of NO3Ag and 3cm under the tibia plateau to 7cm of tibia planoid was debrided and cement spacer was used for filling the spaces. Histopathologic examination of the resected specimen confirmed the hydatid cyst. The patient was prescribed albendazole and discharged from the hospital. She is being followed up now
