  • Tibialis Posterior Tendon Transfer Corrects the Foot Drop Component
    456 COPYRIGHT Ó 2014 BY THE JOURNAL OF BONE AND JOINT SURGERY,INCORPORATED Tibialis Posterior Tendon Transfer Corrects the Foot DropComponentofCavovarusFootDeformity in Charcot-Marie-Tooth Disease T. Dreher, MD, S.I. Wolf, PhD, D. Heitzmann, MSc, C. Fremd, M.C. Klotz, MD, and W. Wenz, MD Investigation performed at the Division for Paediatric Orthopaedics and Foot Surgery, Department for Orthopaedic and Trauma Surgery, Heidelberg University Clinics, Heidelberg, Germany Background: The foot drop component of cavovarus foot deformity in patients with Charcot-Marie-Tooth disease is commonly treated by tendon transfer to provide substitute foot dorsiflexion or by tenodesis to prevent the foot from dropping. Our goals were to use three-dimensional foot analysis to evaluate the outcome of tibialis posterior tendon transfer to the dorsum of the foot and to investigate whether the transfer works as an active substitution or as a tenodesis. Methods: We prospectively studied fourteen patients with Charcot-Marie-Tooth disease and cavovarus foot deformity in whom twenty-three feet were treated with tibialis posterior tendon transfer to correct the foot drop component as part of a foot deformity correction procedure. Five patients underwent unilateral treatment and nine underwent bilateral treatment; only one foot was analyzed in each of the latter patients. Standardized clinical examinations and three-dimensional gait analysis with a special foot model (Heidelberg Foot Measurement Method) were performed before and at a mean of 28.8 months after surgery. Results: The three-dimensional gait analysis revealed significant increases in tibiotalar and foot-tibia dorsiflexion during the swing phase after surgery. These increases were accompanied by a significant reduction in maximum plantar flexion at the stance-swing transition but without a reduction in active range of motion.

  • The Postural and Biomechanical Effects of High Heel Shoes: a Literature Review
    1 The Postural and Biomechanical Effects of High Heel Shoes: A Literature Review By Shavonda L. Pannell Faculty Advisor: Dana L. Underkofler-Mercer, B.S., M.S., D.C. April 10, 2012 A Senior Research Project Submitted in Partial Requirement for the Degree of Doctor of Chiropractic 2 ABSTRACT Objective: The purpose of this literature is to provide an overview of literature concerning the postural and biomechanical effects that high heel shoes have on the musculoskeletal system. The implications of postural imbalances, the roles that muscles play in the maintenance of both ideal and imbalanced human posture and certain gait distortions that may occur. Prevention and treatment options are also discussed. Data Collection: The resources utilized included indexed/referenced journal articles, text and reference books. Pubmed, Chiroweb, Chiroaccess and Mantis were databases used to find journal articles and publications related to the effects of posture on the musculoskeletal system and or the effects of high heel shoes on posture and musculoskeletal biomechanics. Results: The keywords high heel shoes, high heeled posture, gait, posture, postural balance, lower crossed syndrome and spinal instability turned up various articles. The most relevant articles were chosen and included in this compilation. Conclusion: An extensive body of literature supports a conclusion that faulty posture due to the wearing of high heels can have detrimental effects on the musculoskeletal system and its biomechanics. The means to evaluate and address faulty posture is crucial in the evaluation and treatment of the biomechanical stresses placed on the musculoskeletal system. Most women who wear high heels have at some point experienced the conditions associated with the faulty body biomechanics.

    PLASTIC SURGERY Coverage of extensive tibial bone exposure in burn patients with three local flaps N Lahouel, P Mokwatlo, E Ndobe Department of Plastic, Reconstructive and Aesthetic Surgery, University of the Witwatersrand, Johannesburg, South Africa Corresponding author: N Lahouel ([email protected]) Covering tibial bone exposure from third degree burns to the lower limbs is a challenging task for the plastic surgeon. We present our experience of covering tibial exposure from burns in three different patients, where four limbs were involved and three muscular flaps were used in conjunction with one another; i.e. the tibialis anterior flap, the medial gastrocnemius flap and the hemisoleus flap. Through the use of this technique, tibial bone exposure, ranging from 15–30 cm, was successfully covered. This technique constitutes a good solution for surgically challenging wounds.

  • Lower Limb Muscle Activation and Kinematics Modifications of Young Healthy Adults While Pushing a Variable Resistance Sled
    Original Article Lower limb muscle activation and kinematics modifications of young healthy adults while pushing a variable resistance sled MARTIN G. ROSARIO 1 , MONICA MATHIS School of Physical Therapy, Texas Woman’s University, Dallas, Texas, United States of America ABSTRACT Introduction: The XPO Trainer used in this research is a novel device which provides low rolling resistance at low speeds with an immediate and automatic proportional increase in resistance with increased speed. Purpose: To examine the impact of using the XPO Trainer on gait and neuromuscular activation at low and high speeds in young, seemingly healthy adults. Materials and Methods: This work consisted of 35 healthy adults (age: 24.9 ± 3.2 years, weight: 149.8 ± 8 lbs, height: 66.6 ± 4.4 inches). Each participant wore accelerometers/gyroscopes sensors around each wrist and ankle, chest, and low back and surface electromyography (EMG) electrodes on their dominant leg over the quadriceps (QUAD), hamstring (HAM), anterior tibialis (TA), and gastrocnemius (GA). To initiate the tasks, participants walked then ran 40 feet with and without the XPO Trainer sled. Subjects did a total of 3 trials per tasks (total of 12) with one minute of rest between tasks to reduce fatigue factor. The data from the EMG and Mobility Lab sensors were then processed and compared through the SPSS 24 system for a repeated-measures ANOVA. Results: EMG- The QUAD muscle exhibited a substantial higher muscle activation between walk (45.39 ± 24.43) and walk push (74.40 ± 56.73) tasks. Gait Parameters- There was a significant modification (p ≤ .05) between the different gait variables and tasks, including cadence, gait speed, stride length and trunk velocity while pushing the sled.

There were four different supination conditions: (a) ankle neutral, 15° inversion (0015), (b) ankle neutral, 30° inversion (0030), (c) ankle 20° % plantarflexion, 15° inversion (2015), and (d) ankle 20° plantarflexion, 30° inversion % (2030). Morphology (pennation angle, fascicle length and muscle thickness) was evaluated by means of ultrasonographic measurements. % Results: Only the reaction duration of the tibialis anterior muscle in the 0015 (p=0.030) % and 0030 (p=0.039) positions and the reaction magnitude of the peroneus longus (p=0.046) and tibialis anterior (p=0.003) muscles in the 0015 condition were significantly U.%Şekir%% higher in white subjects. These parameters were not significantly different in 2015 and 2030 0000900039273598697% supination conditions (p˃0.05). Neither peroneal nor tibial muscle latency were G.%Arslan%% significantly different between ethnicities in any of the four supination conditions 0000900019795699539% (p˃0.05).
