Spinal motion palpation

Adolescent idiopathic scoliosis is a three-dimensional spinal deformity that evolves during adolescence. Combined with static 3D X-ray acquisitions, novel approaches using motion capture allow for the analysis of the patient dynamics. However, as of today, they cannot provide an internal analysis of the spine in motion. In this study, we investigated the use of personalized kinematic avatars, created with observations of the outer (skin) and internal shape (3D spine) to infer the actual anatomic dynamics of the spine when driven by motion capture markers...

STUDY DESIGN: Pre-Clinical. OBJECTIVE: Evaluate sex-dependent differences in the bone healing response to rhBMP-2 in a rat posterolateral spinal fusion model. SUMMARY OF BACKGROUND DATA: Minimal and conflicting data exist concerning potential sex-dependent differences in recombinant human bone morphogenetic protein-2 (rhBMP-2)-mediated bone regeneration in the context of spinal fusion. METHODS: Forty-eight female and male Sprague-Dawley rats (N=24/group), underwent L4-L5 posterolateral fusion with bilateral placement of an absorbable collagen sponge, each loaded with 5 µg of BMP-2 (10 µg/animal)...

This case report discusses the treatment of brachioradial pruritus (BRP) in a 57-year-old white male veteran with chiropractic and acupuncture. The patient presented with findings consistent with a diagnosis of BRP to include sharp pain, burning, and itching at the bilateral upper extremities over the C5 and C6 dermatomes with acquired excoriations over the affected regions. The only known palliative measure was applying icepacks. Plain film radiographs revealed mild degenerative change at the C4-C5 and C5-C6 levels and postural evaluation observed anterior head carriage with forward-rounded shoulders...

Compartment syndrome usually occurs after trauma, fracture, or compression injuries. To the authors' best knowledge, this is the first reported case in the medical literature of a combined gluteal and posterior thigh compartment syndrome after an accidental fall without an associated fracture. A 65-year-old man attended the emergency department of the general hospital in a remote island complaining of a swollen painful thigh. He reported that 24 h previously he had an accidental slip and fall on his overstretching right leg...

Children: adolescents, and young who are adults affected with hematological malignancies (CAYA-H) and who are undergoing intensive phases of cancer treatment, including hematopoietic stem cell transplantation (HSCT), experience diminished functional ability. This study was aimed at assessing the feasibility, efficacy, safety, and satisfaction of an osteopathic intervention in CAYA-H attending an 11-week precision-based exercise program (PEx). All of the participants were given 4-10 treatments according to the prescription ordered by the sports medicine doctor in charge of the PEx, and the following outcomes were assessed: (1) spinal column range of motion (ROM) by palpation; (2) lower and upper limb joints ROM by a goniometer; (3) orthostatic posture by plumb line assessment; (4) chest and abdomen mobility by inspection and palpation; (5) cranial-sacral rhythmic impulse (CRI) by palpation; and (6) adverse effects...

OBJECTIVE: The purpose of this study was to assess a novel method of lumbar spinous process (SP) palpation by using magnetic resonance imaging (MRI) high-signal marker reference standards for verification. METHODS: Clinicians (doctors of chiropractic) in this study used either: (1) the standard/traditional method of identifying the L4 SP using the supracristal plane (n = 14) or (2) a novel method that manually induced sacral motion to identify the L5 and then the L4 SP (n = 54)...

Spinal alignment measurement in spinal deformity research has recently shifted from using mainly two-dimensional static radiography toward skin marker-based motion capture approaches, allowing three-dimensional (3D) assessments during dynamic conditions. The validity and accuracy of such skin marker-based methods is highly depending on correct marker placement. In this study we quantified, for the first time, the 3D spinal palpation error in adult spinal deformity (ASD) and compared it to the error in healthy spines...

BACKGROUND CONTEXT: Synthetic bone graft substitutes are commonly used in spinal fusion surgery. Preclinical data in a model of spinal fusion to support their efficacy is an important component in clinical adoption to understand how these materials provide a biological and mechanical role in spinal fusion. PURPOSE: To evaluate the in vivo response of a nanosynthetic silicated calcium phosphate putty (OstP) combined with autograft compared to autograft alone or a collagen-biphasic calcium phosphate putty (MasP) combined with autograft in a rabbit spinal fusion model...

We recently developed a recombinant growth factor-free bone regenerative scaffold composed of stoichiometric hydroxyapatite (HA) ceramic particles and human demineralized bone matrix (DBM) particles (HA-DBM). Here, we performed the first pre-clinical comparative evaluation of HA-DBM relative to the industry standard and established positive control, recombinant human bone morphogenetic protein-2 (rhBMP-2), using a rat posterolateral spinal fusion model (PLF). Female Sprague-Dawley rats underwent bilateral L4-L5 PLF with implantation of the HA-DBM scaffold or rhBMP-2...

OBJECTIVE: This is a report of the results of 4 facilitated workshops aimed at developing a standardized chiropractic technique curriculum. METHODS: Workshops were held at research conferences during 2014, 2016, 2018, and 2019. Participants were tasked with developing recommendations for diagnostic and therapeutic procedures appropriate for chiropractic technique programs. RESULTS: For diagnostic procedures, there was general agreement among participants that chiropractic programs should include diagnostic imaging, postural assessment, gait analysis, palpation (static, motion, and joint play/springing), global range of motion, and evidence-based orthopedic/neurological tests...

Background: Abaloparatide is a parathyroid hormone receptor agonist that increases bone formation and reduces vertebral and nonvertebral fracture risk in women with postmenopausal osteoporosis. Animal studies indicate abaloparatide stimulates vertebral bone formation and enhances bony bridging and biomechanical stability of fracture calluses. Aims: The current study is evaluating the potential utility for abaloparatide as an adjunct therapy for spinal fusions. Material and Methods: The effects of 14 or 28 days of daily subcutaneous injections of abaloparatide (20 μg/kg/d) or vehicle were evaluated in 32 male Sprague-Dawley rats starting 1 day after noninstrumented posterolateral fusion (PLF) with bone autograft...

The objective of this study was to apply a biodegradable dynamic fixation system (BDFS) for lumbar fusion between articular processes and compare the fusion results and biomechanical changes with those of conventional rigid fixation. Twenty-four mongrel dogs were randomly assigned to 2 groups and subjected to either posterior lumbar fusion surgery with a BDFS or titanium rods (TRs) at the L5-L6 segments. Six animals in each group were sacrificed at 8 or 16 weeks. Fusion conditions were evaluated by computed tomography (CT), manual palpation, biomechanical tests, and histological analysis...

BACKGROUND Music performance is a highly stressful activity, requiring skilled neuromuscular dexterity. A lack of reported strategies for musicians suffering performance-related musculoskeletal disorders (PRMDs) exists. Papers investigating the role that postural distortions or spinal structural anomalies that could play a role in setting the stage for PRMD do not exist. The purpose of this paper was to provide a description and discussion of the use of a specialized upper cervical manual correction at the cranio-cervical junction (CCJ) to treat a violist who had disabling pain in her wrists, arms, neck, and hip...

OBJECTIVE: The objective of this study was to investigate the hemodynamics of blood flow through the V3 region of the vertebral artery contralateral to the side manipulated during different rotary head positions and post-cervical spinal manipulation. METHODS: This quasi-experimental study was performed on 25 healthy, asymptomatic participants, both male and female, between 20 and 30 years of age. Each participant presented with a C0/C1 or C1/C2 cervical facet restriction (as determined by motion palpation)...

STUDY DESIGN: This study was a multi-endpoint analysis of bone graft substitutes implanted as a standalone graft in a clinically relevant Ovine model of instrumented posterolateral spinal fusion (PLF). OBJECTIVE: The objective of this study was to obtain high-quality evidence on the efficacy of commercial bone graft substitutes compared with autograft in instrumented PLF using a state-of-the-art model with a complete range of assessment techniques. SUMMARY OF BACKGROUND DATA: Preclinical and clinical data on the quality of spinal fusions obtained with bone graft substitutes are often limited...

Chondrosarcoma is the second most common primary malignant bone tumor. While the majority arrive de novo, a minority arise from malignant transformation of benign neoplasms, such as osteochondromas. Rarely, chondrosarcomas have been found to originate from other preexisting lesions, such as synovial chondromatosis. A 44-year-old male with a history of a spinal osteochondroma presented with one year of left hip pain and decreased range of motion. On examination, he had a palpable, irregular fullness in the left groin that was minimally tender to palpation...

As spinal fusions require large volumes of bone graft, different bone graft substitutes are being investigated as alternatives. A subclass of calcium phosphate materials with submicron surface topography has been shown to be a highly effective bone graft substitute. In this work, a commercially available biphasic calcium phosphate (BCP) with submicron surface topography (MagnetOs; Kuros Biosciences BV) was evaluated in an Ovine model of instrumented posterolateral fusion. The material was implanted stand-alone, either as granules (BCPgranules ) or as granules embedded within a fast-resorbing polymeric carrier (BCPputty ) and compared to autograft bone (AG)...

Background and aims Fibromyalgia (FM) is characterized by chronic widespread pain and affects approximately 1-3% of the general population. Respiratory function has not been given much consideration in people with FM. Few studies have been published concerning FM and respiratory function and conflicting data still exist. The aim of this study was to compare differences in forced expiration, but also to investigate chest expansion, spinal mobility and segmental pain intensity between a group with fibromyalgia and healthy controls...

OBJECTIVE: To investigate the reliability and validity of an iPhone® application (iHandy® Level) for measuring active lumbar flexion-extension range of motion (ROM) in chronic nonspecific low back pain (CNLBP) patients. METHODS: Fifteen CNLBP patients were recruited. The participants stood in a relaxed position and the T12-L1 and S1-S2 spinal levels were identified through palpation and were marked on the skin. Two blinded examiners used a gravity-based inclinometer and the application in order to measure ROM...

Posterolateral spinal fusion (PLF) is a common procedure in orthopedic surgery that is performed to fuse adjacent vertebrae to reduce symptoms related to spinal conditions. In the current study, a novel synthetic calcium phosphate with submicron surface topography was evaluated as an autograft extender in a validated rabbit model of PLF. Fifty-nine skeletally mature New Zealand white rabbits were divided into three groups and underwent single-level intertransverse process PLF at L4-5 using (1) autologous bone graft (ABG) alone or in a 1:1 combination with (2) calcium phosphate granules (ABG/BCPgranules ), or (3) granules embedded in a fast-resorbing polymeric carrier (ABG/BCPputty )...
