BACKGROUND CONTEXT: To date, many studies have examined how pelvic position affects the spinal curvature and spino-pelvic parameters. However, these studies focus on a static relationship, comparing pelvis and spine in a relaxed or baseline position only. Indeed, the spino-pelvic connection is dynamic, as a subject can easily be taught to rotate their pelvis anteriorly or posteriorly on the femoral head, all while maintaining an erect posture. Therefore, for a true understanding of pelvic influence on the spinal column, it is necessary to examine spino-pelvic parameters in multiple pelvic positions within the same subject...

BACKGROUND AND PURPOSE: To explore the methods of clinical classification in chronic radiation-induced ulcers in the chest wall (CRUCWs). MATERIALS AND METHODS: A total of 64 patients with CRUCWs were treated. We divided the cases into 3 types (mild, moderate, or severe) according to their clinical manifestations. Conservative treatments, axial-pattern myocutaneous or local flaps, or filleted flaps were applied correspondingly. RESULTS: The cases were divided as follows: mild (n = 11), moderate (n = 45), and severe (n = 8)...

To investigate the anatomical distribution of linear and rotational forces during the tackle scenario, male rugby players performed a total of 48 trials, as ball carrier or tackler. Participants wore headgear accommodating three global positioning system units measuring uniaxial acceleration at the occipital region (OR), left tempero-parietal (LT-PR) and right tempero-parietal region (RT-PR). An additional unit was located at the cervico-thoracic spinal region in a custom vest. There was a significant main effect for tackle condition (P < 0...

BACKGROUND: Recent studies showed that finite element model (FEM) combined to CAD/CAM improves the design of braces for the conservative treatment of adolescent idiopathic scoliosis (AIS), using 2D measurements from in-brace radiographs. We aim to assess the immediate effectiveness on curve correction in all three planes of braces designed using CAD/CAM and numerical simulation compared to braces designed with CAD/CAM only. METHODS: SRS standardized criteria for bracing were followed to recruit 48 AIS patients who were randomized into two groups...

Regional fascial motion palpation is often incorporated by osteopathic practitioners to enable them to identify superior thoracic inlet (STI) myofascial somatic dysfunction motion patterns; however without standardized instruction, diagnostic outcomes may vary between examiners. This study proposes a protocol for diagnosing the STI motion pattern that standardizes examiner hand placement, palpatory discrimination, posture, and relative body positioning. The study design incorporated useful infrastructure recommended by the Fédération Internationale de Médecine Manuelle (FIMM) including protocol agreement steps prior to conducting the formal interexaminer reliability study with the goals of attaining >80% interexaminer agreement and kappa values >0...

There is limited information in the literature related to the lower back loading in patients with LBP, particularly those with non-chronic LBP. Toward addressing such a research gap, a case-control study was conducted to explore the differences in lower back mechanical loads between a group of females (n=19) with non-chronic, non-specific LBP and a group of asymptomatic females (n=19). The differences in lower back mechanical loads were determined when participants completed one symmetric lowering and lifting of a 4...

Lameness, thoracolumbosacral pain and reduced range of motion (ROM) often coexist; better understanding of their relationship is needed. The objectives were to determine if thoracolumbosacral movement of horses changes when pain causing lameness is improved by diagnostic analgesia. We hypothesised that reduction of lameness will increase ROM of the thoracolumbosacral region. Thirteen horses with different types of hind limb lameness were trotted in straight lines and lunged on a 10m diameter circle on left and right reins before and after lameness was subjectively substantially improved by diagnostic analgesia...

BACKGROUND: Scapular winging resulting from long thoracic nerve palsy is uncommon but debilitating, and the choice of surgical treatment is inconsistent. The autogenous semitendinosus tendon plays a key role as an interposed tendon graft, although its use in the indirect transfer of the sternal head of the pectoralis major during the treatment of scapular winging has rarely been reported. MATERIALS AND METHODS: A retrospective review was performed during a 9-year period from the clinical data of 26 cases (28 shoulders) with indirect transfer of the sternal head of the pectoralis major with the interposition of an autogenous semitendinosus tendon graft for dynamic stabilization of the scapula...

BACKGROUND: Mammaplasty surgery has been modified in the past few years, as plastic surgeons worked to improve and maintain the breast shape and especially the "bottoming out" of the gland. The classic Pitanguy's technique has been shown to be an anatomically safe technique in the management of the breast. However, as first described, cannot be applied in gigantomastia or in severe breast ptosis cases or in cases of dense breast parenchyma or for a long-lasting breast lift result. Using 2 different modifications, the Pitanguy technique can be applied for breasts of all sizes and for all cases of breast ptosis...

BACKGROUND: To date, the significance of factors purported to be associated with subacromial shoulder impingement (SSI) and what differences, if any, are present in those with SSI compared to a matched asymptomatic population has not been identified. Gaining information about differences between people with SSI and asymptomatic people may direct clinicians towards treatments that impact upon these differences. OBJECTIVE: Compare the assessment findings of factors suggested to be associated with SSI; passive posterior shoulder range, passive internal rotation range, resting cervical and thoracic postures, active thoracic range in standing and scapula positioning between cases experiencing SSI and a matched asymptomatic group (controls)...

Well preserved thoracic vertebrae of Neandertals are rare. However, such fossils are important as their three-dimensional (3D) spatial configuration can contribute to the understanding of the size and shape of the thoracic spine and the entire thorax. This is because the vertebral body and transverse processes provide the articulation and attachment sites for the ribs. Dorsal orientation of the transverse processes relative to the vertebral body also rotates the attached ribs in a way that could affect thorax width...
