BACKGROUND: The stability of a joint depends on the arrangement of the articular surfaces. Thefailure of acetabulum to deepen along with associated relaxed capsule can be a causative factor leadingto congenital dislocation of hip in babies. The right traumatic hip dislocation is less uncommon ascompared to left side in adults.OBJECTIVE: To correlate the majority of right-footed population with the bony parameters of hipjoint bilaterally and to find out its association with left congenital and right acquired traumaticdislocation of hip.MATERIAL AND METHODS: As the right footed people are considerably more (90%) than the leftfooted and this study work was correlated with the bones collected from cadavers in Anatomydepartment of KGMC Peshawar from January 2014 to December 2014. We included 14 pairs of femurs,14 pairs of hip bones in this study to see the structural differences when dominant hip joint is comparedwith non-dominant hip joints. The measurements were performed with the help of vernier caliper.RESULTS: The mean horizontal diameter of right (dominant) and left acetabulum was 50.14±0.69 mmand 52.35±0.65mm. The mean horizontal depth of right and left acetabulum was 22.21±0.82mm and25.25±0.52mm. The horizontal diameter of right and left femur was 46.42±0.62mm and 43.85±01mm.The thickness of femoral head was 26.71±01mm on right (dominant) side but this thickness was29.17±01mm on left side.CONCLUSION: The left acetabulum was having a significant larger diameter in adult, allowing thesmaller left femoral head to fit snugly which can be correlated with the more common left congenitaldislocation hip. On the other hand, in adults, the left acetabulum is deeper, allowing the thicker left headof femur as an adjustment for weight bearing functionwhile the larger rightfemoral head fit into acomparatively shallow socket. This may be a factor to improve mobility at the cost of stability; as righttraumatic dislocationhip is less uncommon as compared to left side.KEY WORDS: Hip joint, Ball and socket joint.

Results Of Treatment

The immediate results of treatment of 72 children aged 7 to 12 years with aseptic necrosis of the femoral head after bloodless reduction of congenital hip dislocation were analyzed. When treating patients, the following types of surgical treatment were used:extra-articular or open centering of the femoral head with intertrochanteric-torsion-varizing or devarizing and rotational osteotomy of the femur with bringing down the greater trochanter in the caudal direction. In all patients, pain and lameness disappeared, internal rotation of the lower extremities when walking, and the range of motion in the hip joint improved. Improved radiometric parameters characterizing the ratio of the acetabulum and the head of the femur and the angular values of the hip joint and proximal femur.

Exercise-induced spin-spin relaxation time (T2) shifts in magnetic resonance (MR) images were used to test the hypothesis that more muscle would be used to perform a given submaximal task after 5 wk of unweighting. Before and after unilateral lower limb suspension (ULLS), 7 subjects performed 5 sets of 10 unilateral concentric actions with the quadriceps femoris muscle group (QF) at each of 4 loads: 25, 40, 55, and 70% of maximum. T2-weighted MR images of the thigh were collected at rest and after each relative load. ULLS elicited a 20% decrease in strength of the left unweighted QF and a 14% decrease in average cross-sectional area (CSA) with no changes in the right weight-bearing QF. Average CSA of the left or right QF showing exercise-induced T2 shift increased as a function of exercise intensity both before and after ULLS. On average, 12 +/- 1, 15 +/- 2, 18 +/- 2, and 22 +/- 1 cm2 of either QF showed elevated T2 for the 25, 40, 55, and 70% loads, respectively, before ULLS. Average CSA of the left but not the right QF, showing elevated T2 after ULLS, was increased to 16 +/- 2, 23 +/- 3, 31 +/- 7, and 39 +/- 5 cm2, respectively. The results indicated that unweighting increased exercise-induced T2 shift in MR images, presumably due to greater muscle mass involvement in exercise after than before unweighting, suggesting a change in motor control.

Abstract The aim of this case study is to present arthroscopic treatment of recurrent hip instability after acute post-traumatic posterior hip dislocation with a fracture of the posterior acetabular wall. A male patient aged 35 suffered a dislocation of the right hip joint with a fracture of the posterior acetabular wall due to an accident. The fracture was stabilized during emergency surgery with a locking compression plate, and the patient was released home in a hip brace. Multiple dislocations of the hip joint followed with the implant being confirmed as stable. Decision was made to qualify the patient for a right hip arthroscopy. During the surgery, ligamentum teres was reconstructed using gracilis and semitendinous muscle grafts, followed by the labrum and joint capsule repair, where the surgery that stabilized the acetabular wall fracture had damaged them. There were no complications following the procedure. Short-term follow-up of 3 months demonstrates the patient has a stable hip, reduced pain and has returned to pre-injury activities.

Introduction: CHD is a condition, which is frequent in pediatrics in the Caucasian population, remains rare in the Black population, and exceptional in sub-Saharan Africa. The Patient: We report this first Togolese case of bilateral congenital dislocation of the hip associated with genu recurvatum observed in a newborn received on the second day of life. The Primary Diagnoses, Interventions, and Outcomes: The pediatric examination had noted extension of lower limbs. The thighs were in adduction with a stiff bilateral genu recurvatum. The abduction of the thighs on the pelvis was considerably limited. The Barlow and Ortolani maneuvers showed a protrusion. There was also a camptodactyly of the thumbs and a cleft palate. The rest of the examination was normal. Ultrasound of the hip showed a bilateral congenital dislocation of the hip with an estimated acetabular fundus of 7 mm on both the right and left sides. Ultrasound and radiography of the knees were normal. Conclusion: Clinical examination at birth is the key step in diagnosis of congenital hip dislocation. In situations where diagnosis is difficult, ultrasound is of capital importance. Treatment is in the majority of cases orthopedic.

Purpose: Since the establishment of the principle of weight-bearing methods of treatment in Legg-Calvé-Perthes disease (LCPD), lateral displacement of the femoral head has become an important prognostic factor. Material and Methods: In order to establish reliable boundary lines between orthotopic and subluxated hip, the migration percentage (MP) and the medial joint space (MJS) were determined retrospectively: a) on 166 normal hip radiographs; b) on bilateral arthrograms and radiographs from 37 patients with unilateral LCPD. Results and Conclusion: The mean upper normal values for MP and MJS on normal radiographs were 20.8 and 11.5 respectively. On arthrograms, the corresponding values were 31 and 5.7. The MP is easy to determine on both radiographs and arthrograms, and is recommended for detecting and measuring subluxation in cases with LCPD. MJS is of no advantage for detecting containment in LCPD but may be used in other diseases such as coxitis simplex.

Purpose To evaluate changes in blood circulation of the femoral cortex in rabbits using scintigraphy before and after cable cerclage alone or combined with an intramedullary Kirschner wire. Method Ten New Zealand rabbits were used. For the right femur, a 2-mm-thick cable was placed around the mid-diaphyseal region and squeezed with a 400-N force and locked with a clip. For the left femur, a 1.8-mm Kirschner wire was inserted retrogradely into the medullary canal, and a 2-mm-thick cable was applied using the same technique. The blood perfusion ratio of the region of interest (ROI) before and after surgery was evaluated using scintigraphy. Results For the right femurs, the mean ROI perfusion ratio decreased by 45% from 2.51 to 1.37 after intervention (p=0.001). For the left femurs, the mean ROI perfusion ratio decreased by 56% from 2.12 to 0.92 after intervention (p<0.001). The mean ROI perfusion ratio post-intervention was higher in the right than left femurs (p=0.017). Conclusion Cable cerclage around the femoral cortex significantly decreased blood circulation in the area.

Introduction. The total endoprosthesis replacement is a main method of treatment of congenital dislocation of hip. However, significant disorders of joint, resistant muscular contractures create technical complications under operation and force to apply various surgical tactics. Methods. The analysis was implemented concerning results of Crowe total endoprosthesis replacement in 69 patients with one-sided high hip dislocation type IV operated on the basis of traumatological orthopedic department of Saratovskii research institute of traumatology and orthopedics during 2010-2015. The treatment of patients was implemented using original genuine technique including total endoprosthesis replacement of hip joint combined with double V-subtrochanteric osteotomy. Results. The pathological types of implantation in operated hip joint are absent. On the whole, one can notice amelioration of bio-mechanical indices: cycle of step, period of double support, coefficient of rhythm. Among systemic complications of total endoprosthesis replacement one is to mark out phlebothrombosis established in 3 patients (7.1%) that was conditioned by sedentary state of patients. Among specific complications one stated dislocation related to inobservance of restrictive orthopedic regimen in 1 (2.4%) patient. None case of instability of prosthesis and difference in length of extremities in average periods of observation more than on 0.5 cm was established. This is a proof of effectiveness of developed technique of correcting V-subtrochanteric osteotomy. Therefore, the proposed technique of femoral bone osteotomy permitted to ameliorate the results of treatment and to diminish number of complications. The applied technique permits to obtain satisfactory clinical and technical results of surgical treatment of patients with high hip joint dislocation. The osteotomy permitted to eliminate difference in length of bones of patients and at that to ameliorate conditions for union of distal and proximal fragments of femur bone at the expense of larger surface of their contact.

Foot plantar pressure is the pressure field that acts between the plantar region of the foot and supporting ground. The pressure exerted on the variable region of the foot can be determined using discrete pressure sensors. Information obtained from these sensors is useful in the measurement of gait and posture for diagnosing various problems associated with a lower limb, footwear design, and sports biomechanics. This project is aimed to design a portable in-shoe plantar pressure and gyroscope-based gait angle measurement system. Six Force Sensitive Resistor (FSR) placed in the sole (hallux, 1st, 5th metatarsal, midfoot lateral, midfoot medial and heel respectively) detects the plantar pressure and gyroscope placed at the ankle, knee and hip help measure the orientation and angle of joint movement during various phases of gait. The study among 16 male and 16 female subjects illustrated the significant pressure variation (p<0.0001, t=5.17 with α=95%). Similarly, there was a significant difference in pressure between normal and fast walking speed (p<0.0001, t=5.88) with mean values of 353Kpa and 426Kpa respectively. The mean pressure value for slow walking speed was 423Kpa while there was no significant variation between slow and normal walking speeds (p=0.62, t=1.98). Plantar pressure increased linearly with an increase in the body weight of a person as well. The mean pressure for the 45-50 age group was 313.25Kpa and that for 70-75 was 449Kpa. The study among 10 diabetics and 10 non-diabetic subjects illustrated significantly higher pressure on 1st and 5th metatarsal on diabetic subjects (p=0.0207 and t=2.536). The movement of ankle, knee and hip joint is visualized using the 3D model of a lower limb through processing software. The study illustrated the range of ankle joint movement between -60(dorsiflexion) to 200(plantarflexion), for knee joint was 00 to 300 (flexion) and that for hip joint was -50(extension) to 400(flexion). There was a significant difference in angular values for all three joints while climbing up and down the staircase as compared to walk in a level surface.

This study was aimed to find out the variations of the femoral head diameters in relation to sex in Bangladeshi people. The study was based on 123 paired human femurs (radiological view) of which 52 were male and 71were female. It was observed that the mean vertical and transverse diameters of the head of the male femur were significantly greater than that of female (P<0.001).No statistical significant difference was present between the measurement of the right and left side of the same sixth identification points that were derived from the vertical and transverse diameters of the head of the femur were higher in males than in females. The results showed that diameters of the femoral head as well as the identification points that are derived from them are of use in sex identification. The present study is of value to the forensic experts, orthopaedicians and prosthetists as it gives the idea about the dimensions of the femoral head in the present area.   doi: 10.3329/taj.v18i2.3172 TAJ 2005; 18(2): 84-88
