Aim. Determination of the optimal diagnostic and treatment strategy in patients with scoliosis and having an anatomic shortening of the lower limb. Patients and methods. Surgical correction of scoliosis held 8 to patients with lower limb shortening caused by congenital dislocation of the hip (n = 3), anatomic shortening of the lower extremities due to the hip (n = 1), the shin bone (n = 4). Shortening before correction and fixation of scoliosis ranged from 6 to 14 cm, after surgery on the spine has been reduced by 2-4 cm achieved reduction or removal of pelvic obliquity . The second stage, after 8-12 months, performed surgery to address shortening of the lower extremity. Osteotomy of the femur with the imposition of a spoke - rod device held 4 tibial osteotomy with the imposition of external fixation device Spoke - and 4 patients and in the subsequent limb lengthening was performed by compression-distraction osteosynthesis. Results. After the dorsal stabilization and fixation of the spine scoliosis correction averaged 64% (from 76 to 27 °), the value of breast / thoracolumbar kyphosis after surgery failed to bring to the physiological (average 43 °). Misalignment of the pelvis is reduced by 67 % (from 24 to 8 °), which reduced the shortening of the lower limb by an average of 3 cm (compensation relative shortening by reducing or eliminating the distortion of the pelvis). Further compensation shortening held on the second stage of treatment, representing an osteotomy and subsequent elongation of the femur or tibia bones by transosseous compression-distraction osteosynthesis by Ilizarov. Conclusions. Multi-stage treatment reduced the degree of spinal deformity, to normalize the balance of the body, restore the function of distance without the use of orthotic devices and means of support.

Mining Dump Truck

The rear multi-stage cylinder direct-acting hydraulic body hoist mechanism is widely used in mining dump truck. The working principle of the body hoist mechanism is introduced. The dumping process is simplified through the introduction of “dumping line” and the variation of ore mass and hoist torque are analyzed. The optimization design of the position of body hoist mechanism is done using Maple software on the basis of direct search method aimed at minimizing the initial hoist force and the stroke of cylinder and maximizing the hoist force arm when the second stage cylinder starts to stretch out.

Assisted Navigation

High tibial osteotomy (HTO) is a procedure which aims to change the mechanical axis of the lower limb, transferring the body weight across healthy articular cartilage. Several studies have shown that accurate correction is the leading predictor for success.In this article, we systematically review the computer-assisted techniques that have been used in attempts to increase the accuracy of the surgery and improve postoperative outcomes. The results of the cadaveric and clinical studies to date are presented and the benefits and pitfalls of navigation are discussed.

Different Parts

Ayurveda in its principle has given importance to individualistic approach rather than generalize. Application of this examination can be clearly seem like even though two patients suffering from same disease, the treatment modality may change depending upon the results of Dashvidha Pariksha. Prakruti and Pramana both used in Dashvidha Pariksha. Both determine the health of the individual and Bala (strength) of Rogi (Patient). Ayurveda followed Swa-angula Pramana as the unit of measurement for measuring the different parts of the body which is prime step assessing patient before treatment. Sushruta and Charaka had stated different Angula Pramana of each Pratyanga (body parts). Specificity is the characteristic property of Swa-angula Pramana. This can be applicable in present era for example artificial limbs. A scientific research includes collection, compilation, analysis and lastly scrutiny of entire findings to arrive at a conclusion. Study of Pramana and its relation with Prakruti was conducted in 1000 volunteers using Prakruti Parkishan proforma with an objective of evaluation of Anguli Pramana in various Prakriti. It was observed co-relating Pramana in each Prakruti and Granthokta Pramana that there is no vast difference in measurement of head, upper limb and lower limb. The observational study shows closer relation of features with classical texts.

Central Argument

Serious illness often left the body weak and lean, full of the ‘footsteps of disease’; it wasn’t until full strength and flesh had returned that the patient was pronounced back to health. This chapter explores the second stage of recovery in contemporary perceptions, the restoration of strength, or ‘convalescence’. It asks how the patient’s growing strength was measured and promoted, and unveils a concept of convalescent care, ‘analeptics’. The central argument is that both the mechanisms and the measures for the restoration of strength were intimately connected to the ‘non-natural things’, six dietary and life-style factors. The opening sections explain why the body was weak after illness, and categorize the convalescent within contemporary schemes of health. The rest of the chapter is structured around the signs of increasing strength, each of which was associated with a particular non-natural: ‘the final purge’, ‘sleeping through the night’, ‘feeling hungry’, ‘growing cheerful’, and ‘sitting up to going abroad’.

AbstractObjective:Knowledge of injuries of earthquake victims is important to plan relief efforts. This cross-sectional study was conducted following the 08 October 2005 earthquake in Northern Pakistan to determine the pattern of injuries sustained and their relationship with age and gender in order to identify the medical needs in an earthquake-affected zone.Methods:The study was conducted between 13 October and 23 October 2005 at the Emergency Relief Hospital, Doraha, Mansehra. From the 1,700 patients registered in the hospital, 310 were sampled randomly for the study. Demography and details of the patients' injuries were noted by history and physical examination. Twelve cases were omitted due to incomplete data.Results:Of the cases, 54% were female. Children ≤10 years old formed the largest age group. Isolated bone injuries were present in 41%, soft tissue injuries in 36%, and mixed injuries in 23% of the patients.The most common bone injury was lower limb fracture (52%), while the most common non-bone injury was non-infected, soft tissue wounds on the limbs (33%). Among patients with soft tissue injuries, gangrenous wounds were present in 9%, and grossly infected wounds in 30% (20% on limbs and 10% on rest of the body).Conclusions:The population injured during the earthquake showed a higher proportion of females and children ≤10 years old, and lower limb bone injuries. The data highlight the need to address orthopedic, pediatric, and women's health issues, and for logistic arrangement of relevant diagnostic and therapeutic facilities at the initial stages of relief activities after earthquakes.

Postural Orientation

We performed a whole-body mapping study of the effect of unilateral muscle vibration, eliciting spindle Ia firing, on the control of standing and walking in humans. During quiet stance, vibration applied to various muscles of the trunk-neck system and of the lower limb elicited a significant tilt in whole body postural orientation. The direction of vibration-induced postural tilt was consistent with a response compensatory for the illusory lengthening of the stimulated muscles. During walking, trunk-neck muscle vibration induced ample deviations of the locomotor trajectory toward the side opposite to the stimulation site. In contrast, no significant modifications of the locomotor trajectory could be detected when vibrating various muscles of the lower as well as upper limb. The absence of correlation between the effects of muscle vibration during walking and standing dismisses the possibility that vibration-induced postural changes can account for the observed deviations of the locomotor trajectory during walking. We conclude that the dissimilar effects of trunk-neck and lower limb muscle vibration during walking and standing reflect a general sensory-motor plan, whereby muscle Ia input is processed according to both the performed task and the body segment from which the sensory inflow arises.

Straight Ahead

We tested the hypothesis that common principles govern the production of the locomotor patterns for both straight-ahead and curved walking. Whole body movement recordings showed that continuous curved walking implies substantial, limb-specific changes in numerous gait descriptors. Principal component analysis (PCA) was used to uncover the spatiotemporal structure of coordination among lower limb segments. PCA revealed that the same kinematic law accounted for the coordination among lower limb segments during both straight-ahead and curved walking, in both the frontal and sagittal planes: turn-related changes in the complex behavior of the inner and outer limbs were captured in limb-specific adaptive tuning of coordination patterns. PCA was also performed on a data set including all elevation angles of limb segments and trunk, thus encompassing 13 degrees of freedom. The results showed that both straight-ahead and curved walking were low dimensional, given that 3 principal components accounted for more than 90% of data variance. Furthermore, the time course of the principal components was unchanged by curved walking, thereby indicating invariant coordination patterns among all body segments during straight-ahead and curved walking. Nevertheless, limb- and turn-dependent tuning of the coordination patterns encoded the adaptations of the limb kinematics to the actual direction of the walking body. Absence of vision had no significant effect on the intersegmental coordination during either straight-ahead or curved walking. Our findings indicate that kinematic laws, probably emerging from the interaction of spinal neural networks and mechanical oscillators, subserve the production of both straight-ahead and curved walking. During locomotion, the descending command tunes basic spinal networks so as to produce the changes in amplitude and phase relationships of the spinal output, sufficient to achieve the body turn.
