摘要:

In lower-limb pathomechanical patient populations, one of the greatest impediments to energy-efficient ambulation is the development of a genu recurvatum deformity. When this deviation occurs, the thigh and lower limb segments move posteriorly in direct opposition to the anterior advancement of the proximal body mass over the fixed distal base of support. Genu recurvatum usually is an acquired deformity secondary to changes of the distal skeletal joint alignments and compensatory movement patterns. The alignment of the distal base of support determines the load bearing and functional motion available to the proximal knee joint during ambulation and can serve either to promote or disrupt the required sagittal plane limb advancementThis article describes three distinct pathomechanical profiles of posterior knee joint deviation in relation to the primary planes of motion. The distinction between an initial hyperextension moment and an acquired recurvatum deformity is presented in terms of predictability, prevention and correction of joint deformation. Gait training and orthotic design criteria are discussed as they relate to a comprehensive rehabilitation program to maximize both structural and functional outcomes for patients with lower-limb instabilities and deformities

摘要:

A new cervical-thoracic orthosis is described which provides cervical-thoracic stabilization, and is possibly less intrusive, less conspicuous, and more comfortable than other orthoses currently available. It rests and pivots on the wearer's shoulder, thereby transferring the weight of the head, via the shoulder pivot, to the wearer's shoulder and midsection. Our admittedly limited results show that the orthosis is relatively cool and comfortable, easy to clean, and aesthetically pleasing as it can be worn under clothing and concealed from general view. The orthosis is formed from one continuous piece of a suitably rigid material and generally conforms to the contours of the wearer's body. One size fits most users; however, it can be customized to conform to the contours of the wearer, even while the wearer is positioned in a corrective posture. The orthosis can also be used to incrementally adjust the position of the wearer's head or the curvature of the wearer's spine. A preliminary process for mass producing the orthosis has been demonstrated with a view toward a more sophisticated method of manufacture. Physicians have prescribed the orthosis for seven patients, and the initial qualitative results presented here are quite encouraging

摘要:

The emphasis for orthotic treatment of the foot and ankle following injury has shifted from complete immobilization to allowing functional activity to occur in stable planes. The literature supports this concept of orthotic treatment where tolerable flexibility and normal function with conservative intervention will best lead to a favorable clinical outcome. Specifically, the use of orthopedic ankle-support boots in treating acute and chronic ankle injury has not been studied adequately to date.In a retrospective study, 180 patients were surveyed who had been fitted with orthopedic ankle-support boots between 1991-1996 following acute and chronic foot and ankle injury. The boots comprise unique features, including medial and lateral stabilizers, firm reinforced heel cups, a patented lacing system, and torsion-resistant sole design. Clinical outcomes were obtained from a survey mailed to patients. An 18% return rate (33 patients) was achieved. Results indicated that 42% of patients were prescribed the boots to replace an existing orthosis, while 29% claimed that the boots were prescribed to avoid surgery. Eighty-six percent of subjects were able to resume their normal activities immediately once fitted. Only 13% of all subjects had surgical intervention following use of the boots. A high level of compliance was achieved; 86% were still wearing the boots at the time of survey and 77% would prefer the same treatment again.The study indicated positive clinical outcomes with the use of orthopedic ankle-support boots as demonstrated by a speedy return to normal activities; reduced time on disability; its application in acute, chronic, and prophylactic stages; its favorable response over other commonly used modalities; and a high level of compliance

摘要:

The author suggests that what he refers to as the “zone of integrated balance” is an important variable in determining the alignment of lower limb prosthesesBy using a force plate that objectively measures the center of pressure on the prosthetic foot, the weight and load lines of the patient can be determined. The distance between these lines is the “zone of integrated balance.” The author suggests that the closer the lines approximate one another the more integrated is the balance of the prosthetic side in relation to the overall balance of the amputeeIn the author's clinical experience, a narrow zone of 0 to 1 cm has been found to be reasonable in providing an appropriate prosthetic alignment

摘要:

Currently, there exist two accepted treatment protocols for spondylolytic patients— the Williams Flexion Orthosis and a polymer LSO, such as the Boston Overlap Orthosis. Literature ranging from the late fifties through the present are reviewed to determine the biomechanics and effectiveness of these protocolsA prototype was made that combined the two orthoses and radiographs were taken to determine its effectiveness. The anterior section was adapted from Williams and the posterior section, from the polymer, and it was molded to a positive cast of the patient. Radiographs were also taken showing the difference in the lumbar spine alignment between the two orthoses used on our patient.This article explains the importance of maintaining a posterior pelvic tilt and emphasizes the importance of sagittal flexion through the use of a new design
