Functional evaluation of patients with anterior cruciate ligament injury. A transversal analytical study.
2018
Abstract Objective To evaluate, by means of biomechanical analysis, functional alterations of gait and balance of patients with anterior cruciate ligament (ACL) injury. Material and methods Transversal analytical study on 64 people, 27 health subjects and 37 patients with ACL injury. Biomechanical analysis of gait in all individuals was performed by means of four tests: (1) kinematic test, to characterize gait pattern; (2) kinetic test, to characterize forces against the floor, duration of treads, symmetry of both legs, and the reproducibility of the gait; (3) pivot-shift test, to analyze the rotational stability of the knee on the sagittal axis; and (4) equilibrium test. Results Alteration…
"Only Spinal Fixation" as Surgical Treatment of Cervical Myelopathy Related to Ossified Posterior Longitudinal Ligament: Review of 52 Cases.
2020
Background Ossification of the posterior longitudinal ligament (OPLL) is a hyperostotic condition resulting in a progressive narrowing of the spinal canal and subsequent neurologic deficits. Although systemic and local factors in combination with genetic abnormality have been considered in its etiopathogenesis, OPLL remains a poorly understood pathology. Surgical management of OPLL and the choice of the most appropriate treatment are still controversial issues. Here the authors report a series of OPLL-affected patients treated by “only-fixation” technique. Methods Between June 2012 and June 2019, 52 patients having OPLL were treated by a surgical strategy involving only spinal fixation with…
Stability of the upper neck during isometric neck exercises in rheumatoid arthritis patients with atlantoaxial disorders.
2008
To study the effect of isometric neck strength exercises on upper cervical stability in patients with rheumatoid arthritis (RA).Twenty patients with a mean (SD) age of 58 (9) years and duration of RA of 27 (10) years volunteered for the study. Lateral radiographs of the cervical spine were taken to measure the current atlantoaxial distance (AAD) in flexion and extension. Maximal isometric neck flexion and extension strength values were measured by a dynamometer. Thereafter, AADs were measured from radiographs taken at 80-90% resistance of maximal strength.According to the full flexion radiographs at baseline, the patients were classified into three groups: eight patients without anterior at…
Lumbar spine mobility in Marfan syndrome
1993
Low back pain symptoms and lumbar spine mobility were assessed by questionnaires and by clinical and radiological measurements in 32 patients with Marfan syndrome. Frequently occurring low back pain was reported by 19% of the patients, but the disability was slight in all of them. Flexion and extension mobility of the lumbar spine (L1-S1) assessed from radiographs was 59.9 degrees and 13.2 degrees, respectively. Mean lumbar angular mobility between flexion and extension radiographs was 7.4 degrees at L1-2, 13.2 degrees at L2-3, 16.0 degrees at L3-4, 19.3 degrees at L4-5 and 18.3 degrees at L5-S1. No correlation was found between the manual assessment of lumbar segmental instability and radi…
The value of MRI in the evaluation of the ACL deficient knee and in the post-operative evaluation after ACL reconstruction
1993
To evaluate the usefulness of magnetic resonance imaging (MRI) in the exploration of the anterior cruciate ligament (ACL) deficient-knee, a total of twenty-five patients with chronic instability of the knee joint and who underwent both MRI and arthroscopy were studied prospectively. Twenty-three of these patients underwent an intra-articular reconstruction of the ACL with bone-patellar tendon-bone autografts. For the ACL lesions MRI had a sensitivity of 95.8%, a specificity of 100% and a diagnostic accuracy of 97.7%. Associated bowing of the PCL was seen in 20 cases of the study group. For the associated meniscal lesions MRI had a sensitivity of 77.7%, a specificity of 94.7% and a diagnosti…
Retrospective review of L3 myelomeningocele in three age groups: should posterolateral iliopsoas transfer still be indicated to stabilize the hip?
2005
The data from 58 hips in 29 myelodysplastic children with L3 paralysis has been reviewed retrospectively. Posterolateral transfer of the iliopsoas (Sharrard technique) was performed on all hips to correct muscle imbalance between 1975 and 1992. The average length of follow-up was 21 years. Preoperatively, 58.6% of the hips were either subluxated or dislocated (these were surgically reduced at the same stage). Radiological assessment revealed that 91.4% of the hips were stable at preschool age and 84.5% in adolescence. Of the patients 86% were functional walkers at preschool age and 75.8% in adolescence. Downward transitions in seven patients were related to the presence of scoliosis, spasti…
Kinematic parameters after tibial nonunion treatment using the Ilizarov method
2021
Abstract Background Analysis of the outcomes of Ilizarov treatment of tibial nonunion shows functional deficits in the lower limbs of some patients. Biomechanical gait parameters are an important measure for assessing musculoskeletal disorder treatments that aim to restore normal gait. The purpose of our study was to compare the kinematic parameters in patients with tibial nonunion treated using the Ilizarov method and those in a control group of healthy volunteers. Methods The study population consisted of 23 patients (age 54.9 ± 16.4 years) who were treated for tibial nonunion using the Ilizarov method, as well as 22 healthy adult controls (age 52.7 ± 10.6 years). Kinematic parameters wer…
Kosaki overgrowth syndrome: A novel pathogenic variant in PDGFRB and expansion of the phenotype including cerebrovascular complications
2020
Heterozygous activating variants in platelet-derived growth factor, beta (PDGFRB) are associated with phenotypes including Kosaki overgrowth syndrome (KOGS), Penttinen syndrome and infantile myofibromatosis (IM). Here, we present three new cases of KOGS, including a patient with a novel de novo variant c.1477A > T p.(Ser493Cys), and the oldest known individual age 53 years. The KOGS phenotype includes characteristic facial features, tall stature, scoliosis, hyperelastic thin skin, lipodystrophy, variable intellectual and neurological deterioration, and abnormalities on brain imaging. Long-term outcome is unknown. Our cases confirm the phenotypic spectrum includes progressive flexion contrac…
Symmetry function in gait pattern analysis in patients after unilateral transfemoral amputation using a mechanical or microprocessor prosthetic knee
2021
AbstractBackgroundAbove-knee amputations (AKAs) contribute to gait asymmetry. The level of asymmetry is affected by the type of knee prosthetic module. There is limited evidence suggesting that more technically advanced solutions (microprocessor modules; MicPK) are superior to less advanced ones (mechanical modules; MechPK). The study aimed to evaluate the variable range of hip and pelvic joint movements during gait and look for differentiating areas with an increased level of asymmetry of the gait cycle in individuals who underwent an AKA and are equipped with MicPK or MechPK.MethodsTwenty-eight individuals participated in the study; 14 were assigned to a study group of individuals who und…
Treatment of painful radiculopathies with capsaicin 8% cutaneous patch.
2017
The treatment of neuropathic pain due to low-back (lumbosacral) radiculopathies, a common source of neuropathic pain, is challenging and often requires a multimodal therapeutic approach. The capsaicin 8% patch is the first topical analgesic licensed for peripheral neuropathic pain. To evaluate this treatment, a subset of patients with painful radiculopathy (lumbar and cervical, including ventral and dorsal rami) enrolled into the multicenter, non-interventional QUEPP study (QutenzaOf the 1044 study participants, 50 were diagnosed with painful radiculopathy as only peripheral neuropathic pain syndrome and were eligible for evaluation. Patients received a single treatment (visit 1) with follo…
