    PMID: 28435587 MyJurnal DOI: 10.5704/MOJ.1503.015
    This study was to evaluate the morphological features of degenerative spinal stenosis and adequacy of lateral canal stenosis decompression via unilateral and bilateral laminectomy. Measurements of facet joint angulation (FJA), mid facet point (MFP), mid facet point distance (MFPD), the narrowest point of the lateral spinal canal (NPLC) and the narrowest point of the lateral spinal canal distance (NPLCD) were performed. At L4L5 of the right and left side, the mean distance between the lateral border of the dura and MFP was 1.0 ± 0.2 cm and 1.0 ± 0.3cm respectively. The mean NPLC was seen at 0.7 ± 0.3 and 0.7 ± 0.3 cm cm from the dura. At L5S1 of the right and left side, the mean distance between the lateral border of the dura and MFP was 1.2± 0.2 and 1.3 ± 0.2 cm respectively. The mean NPLC was seen at 0.8 ± 0.4 and 0.9 ± 0.5 cm from the dura. Unilateral laminectomy may result in incomplete decompression.

    Introduction: The New Zealand White (NZW) rabbit model is commonly used for the research of
    posterolateral intertransverse lumbar arthrodesis. The standard approach reported by many
    researchers are a muscle splitting approach through the intermuscular plane between multifidus and longissimus muscles. Methods: In this research the fusion bed was exposed by retracting the three groups of paraspinal muscles (multifidus, longissimus and iliocostalis) medially. Results: This alternative method showed good exposure of the transverse processes and intertransverse membrane with less bleeding from the muscles observed. No death due to surgical complication was observed out of twenty-four rabbits operated. Conclusion: An easy and safe method for performing posterolateral intertransverse lumbar arthrodesis was demonstrated and recommended as an alternative approach for surgery on New Zealand White rabbits.

    Aberrant right subclavian artery is a rare cause of dysphagia. This is a congenital anomaly with the right
    subclavian artery originating from the dorsal part of the aortic arch and coursing through the mediastinum
    between the esophagus and the vertebral column. We report a case of a patient with chronic dysphagia
    caused by this condition. We further discuss the case with regards to its clinical features and options of
    management.

    The integration of human knowledge between the medical and health care sciences with revealed knowledge was established since the era of Al-Razi (Rhazes), Ibn Sina (Avicenna), Ibn Rushd (Averroes), AlZahrawi (Albucasis) and others. However, the glorious period of Islamic medicine gradually declined after the period of 'Abbasiyyah and 'Uthmaniyyah. At present, many scholars tend to separate the modern medicine and the revealed knowledge, resulting in the disconnection between these two fields. There is little to suggest the presence of reference collections that integrate the Qur’an and Hadith with medicine. This review aimed to fill that gap. Relevant Qur’anic verses and authentic Hadith of the Prophet Muhammad (peace be upon him; henceforth PBUH) in relation to a specific field in medicine i.e. the anatomy of human musculoskeletal system was extracted. The musculoskeletal system is unique in which it forms the ‘backbone’ of normal human posture. The system plays a vital role in maintaining human daily activities. From this review, it is noted that many Qur’anic verses and Hadith relate to the musculoskeletal system. A few examples include the number human joints and its relationship with the daily prayers (Salah), the daily charitable act recommended to all Muslim, the coccyx bone that is indestructible and shall be the source for human resurrection during the hereafter, and others. These examples necessitate for a more in-depth analysis to enlighten the revealed knowledge from the medical perspective.

  7. Fulltext Effect of latent myofascial trigger points on strength measurements of the upper trapezius: a case-controlled trial
    Doraisamy MA, Anshul
    Physiother Can, 2011;63(4):405-9.
    PMID: 22942517 DOI: 10.3138/ptc.2010-27
    PURPOSE: The purpose of this article was to determine whether strength is altered in the upper trapezius in the presence of latent myofascial trigger points (MTrP).

    METHODS: This study was case controlled and used convenience sampling. The sample recruited was homogeneous with respect to age, sex, height, and body mass. Participants were assessed for the presence of latent MTrP in the upper trapezius and placed into two groups: an experimental group that had latent MTrP in the upper trapezius and a control group that did not. Eighteen women (mean age 21.4 y, SD 1.89; mean height 156.9 cm, SD 4.03; and mean body mass 51.7 kg, SD 5.84) made up the experimental group, and 19 women (mean age 20.3 y, SD 1.86; mean height 158.6 cm, SD 3.14; and mean body mass 53.2 kg, SD 5.17) made up the control group. We obtained strength measurements of the non-dominant arm using a handheld dynamometer and compared them between the two groups.

    RESULTS: The difference in the strength measurements between the two groups was not statistically significant (p=0.59).

    CONCLUSIONS: The presence of latent MTrPs may not affect the strength of the upper trapezius.

  9. Fulltext Dynamic measurement of axial vertebral rotation and rotational flexibility in scoliosis by flouroscopic method
    Lim HH, Ong CH
    Med J Malaysia, 2001 Jun;56 Suppl C:41-5.
    PMID: 11814248
    The Pedriolle torsion meter is an established method of vertebral rotation assessment in scoliosis. However, the assessment of scoliosis by this method is static and indirect. The objective of this study is to compare the accuracy of a direct method of assessing scoliosis rotation by fluoroscopy compared to the Pedriolle torsion meter. Secondly, to determine that vertebral body rotation changes with supine posture compared to erect position. Eight volunteers with idiopathic scoliosis were assessed for the apical vertebral rotation with this method and the Pedriolle torsion meter. These patients were also assessed in the supine and erect position with the fluoroscopic method to determine if the apical vertebral rotation would change with posture. The mean Cobb angle of the curves was 62.8 degrees (range 45 degrees to 86 degrees). The mean apical vertebral rotation in a standing position was assessed to be 21.5 degrees by Pedriolle torsion meter and 29 degrees by the fluoroscopic method. This difference was not statistically significant by the student t-test. In most patient, the rotation of vertebrae improved by a varying degree ranging from none to 24 degrees in the supine position. In conclusion, the fluoroscopic method is an alternate mean of measuring vertebrae rotation in idiopathic scoliosis, with comparable accuracy to the Pedriolle torsion meter method. The amount of vertebral rotation changes with posture of the patient.

  10. Fulltext Relevance of Cobb method in progressing sagittal plane spinal deformity
    Harwant S
    Med J Malaysia, 2001 Dec;56 Suppl D:48-53.
    PMID: 14569767
    Non-traumatic, progressing sagittal plane deformities are uncommon, but can lead to neurological deficit if untreated. The currently used Cobb method in assessing sagittal spinal curves is based on measuring the tilt of the end vertebrae. This study describes a method which quantifies the apex of the sagittal curve based on the apical quality as measured by the radius of curvature. Both this and the Cobb methods are compared to determine which has relevance in determining neurological deficit. Radiographs of 36 consecutive patients diagnosed with congenital kyphosis were reviewed. Twenty-four had normal neurology and 12 had neurological deficit as a result of sagittal curve progression. Both groups of patients had their weight bearing lateral radiographs analysed to measure the sagittal curve by the usual Cobb method and the Radius of Curvature method. There was no difference for the Cobb values for negative neurology and patients with positive neurological deficit (p = 0.3). There was a difference in these two groups when the radius of curvature method was used (p < 0.0005). The Radius of Curvature method has more relevance than Cobb method in quantifying sagittal plane deformity in congenital kyphosis when assessing neurological deficit.

  11. Fulltext Effectiveness of lumbar support with built-in massager system on spinal angle profiles among high-powered traffic police motorcycle riders: A randomised controlled trial
    Mohammad Yusof NAD, Karupiah K, Mohd Tamrin SB, Rasdi I, How V, Sambasivam S, et al.
    PLoS One, 2021;16(10):e0258796.
    PMID: 34665845 DOI: 10.1371/journal.pone.0258796
    Traffic police riders are exposed to prolonged static postures causing significant angular deviation of the musculoskeletal, including the lumbar angle (L1-L5). This postural alteration contributes to awkward posture, musculoskeletal disorders and spinal injury, especially in the lower back area, as it is one of the most severe modern diseases nowadays. Thus, the study aimed to evaluate the effect of lumbar support with a built-in massager system on spinal angle profiles among traffic police riders. A randomised controlled trial (pre-testpost-test control design) was used to assess spinal angle pattern while riding the high-powered motorcycle for 20 minutes. Twenty-four traffic police riders were randomly selected to participate and 12 riders were assigned to the control group and 12 riders to the experimental group. The pre-test and post-test were conducted at a one-week interval. Each participant was required to wear a TruPosture Smart Shirt (to monitor spinal posture). The TruPosture Apps recorded the spinal angle pattern. The data indicated that the police riders using motorcycle seat with lumbar support and built-in massager system showed a huge improvement in maintaining posture which only involves slight spinal angle deviation changes from the spinal reference angle throughout the 20 minutes ride. The data collected then were analysed using the Mann-Whitney test and Wilcoxon signed-ranked test to verify a statistically significant difference between and within the control and experimental groups. There were significant differences in all sensors between the control group and experimental groups (p<0.05) and within the experimental group. According to the findings, it can be said that the ergonomic intervention prototype (lumbar support with built-in massager system) successfully helps to maintain and improve the natural curve of the spinal posture. This indirectly would reduce the risk of developing musculoskeletal disorders and spinal injury among traffic police riders.

    The paramedic team of Advanced Medical and Dental Institute (IPPT), Universiti Sains Malaysia (USM) is often involved in providing medical assistance for various activities organised by the university such as during PIMPIN siswa outdoor training and sport events. Paramedics often faced difficulty in saving injured patients as the current stretcher is rather heavy (5.8 kg) and is not able to be folded to a smaller size. To overcome this problem, i-TAG, a stretcher made of durable two-layer canvas cloth with the size of 170.0 cm x 74.0 cm and equipped with 10 user-friendly rubber handle, has been invented. The upper part of the stretcher has a zip to insert the spinal board if the victim has spinal and head injuries. The i-TAG is also very light with only 1.2 kg in weight, easy to be folded and stored in emergency bags, and can be easily carried by paramedics. The i-TAG innovative product has a positive impact on health and safety services. Using i-TAG, the task to carry patients or injured victims becomes easier, faster, saves energy and subsequently increases the efficacy of the rescue and medical aid tasks by paramedics.

  14. Fulltext Correction using Halo Gravity Traction for Severe Rigid Neuromuscular Scoliosis: A Report of Three Cases
    Mejabi JO, Sergeenko OM, Ryabykh SO
    Malays Orthop J, 2019 Mar;13(1):49-53.
    PMID: 31001385 DOI: 10.5704/MOJ.1903.010
    Severe rigid neuromuscular scoliosis is a major challenge to the spine surgeon due to the possibilities of neurological sequelae from acute correction of the deformity. Halo gravity traction has been considered as a way of reducing the deformity before correction to prevent neurological complications. Three female patients with severe neuromuscular scoliosis aged seven to 13 years with main coronal Cobb angle of 95°-128° and Kyphotic Cobb of 47°-118° having ≤35% flexibility on traction, had between 18 to 23 days of 16 hour/day of halo gravity traction and night time supine traction with 4kg weight for 7-8 hours. They had 28.9% and 18.5% of main coronal and kyphotic Cobb angle correction post-traction respectively. All had posterior instrumentation and post-operatively, they had correction of main coronal Cobb angle of 29°-58° and kyphotic Cobb angle of 30°-77° with no neurological complication. Halo gravity traction is therefore a viable option for reducing post-operative neurological complication in rigid severe scoliosis.

  15. Fulltext Plausible impact of forward head posture on upper cervical spine stability
    Chu ECP, Lo FS, Bhaumik A
    J Family Med Prim Care, 2020 May;9(5):2517-2520.
    PMID: 32754534 DOI: 10.4103/jfmpc.jfmpc_95_20
    The cervical spine is responsible for allowing mobility and stability to the head and neck. Any deviation to the center of gravity of the head results in an increase in cantilever loads, which can be particularly damaging to the upper cervical joints. Excessive neck bending also exaggerates stretching through the cervical spine and all of the spinal structures below. It has been reported that forward head posture (FHP) can cause a multitude of disorders including cervical radiculopathy, cervicogenic headaches and cervicogenic dizziness. Most of these conditions manifest with clusters of painful symptoms and spine dysfunctions. The purpose of this case study is to describe the radiographic imaging considerations and to illustrate the potential impacts in symptomatic adults with FHP. We randomly selected radiographs of three individuals with FHP who had undergone cervical adjustment for cervical pain. The occipito-axial (C0-C2) and atlanto-axial (C1-C2) joints were assessed via the C0-2 distance from the C2 base to the McGregor line (Redlund-Johnell criterion) and the Ranawat C1-2 index, in addition to subjective radiographic parameters. By comparing the radiographs of before-and-after intervention of each patient, a regressive joint spacing was observed from both indices. Such a long-lasting stretching concordant with FHP was assumed to be hazardous to joint stability. A definite conclusion, however, cannot be drawn due to the small sample size and a lack of convincing measurements.

    This study documented details of the dentitions, skulls and other skeletal remains of Crocodylus porosus and Tomistoma schlegelii, from western part of Sarawak, Malaysian Borneo. The remains of both reptiles were exhumed, followed by standard cleaning procedures and then detail morphological assessments were carried out accordingly. Both species show similar structure of vertebral columns, but T. schlegelii has the following unique structures: a long and narrower snout, D-shaped eye sockets, long and sharp pointed protruding quadratojugal bones, straight maxillae and dentary, a smooth surfaced skull, elongated triangular suborbital fenestrae, round shaped internal nares and visible supraoccipital from a dorsal view. C. porosus has heterodont dentition with blunt-pointed and irregular size of teeth whereas T. schlegelii has almost homodont dentition with sharp and similar size teeth. This is the first collection of teeth, skulls and other skeletal remains of both species obtained from Sarawak, and the materials have been used regularly to educate the public through science exhibitions, hoping they will spark the interests of young budding scientists to be involved in wildlife taphonomic studies in the future.

    Clinically, it is sometimes diffi cult to distinguish an infection of the spine from a metastasis. Spinal tuberculosis is common according to its endemic region and adenocarcinoma of the lung is also rising in the incidence worldwide. Similar presentations, with unknown primary, clinical fi ndings and hematological investigations rarely conclude a true diagnosis. Radiologically, the hallmark of spinal infection is erosion of adjacent vertebral endplates and narrowing of the disc space with or without a paravertebral shadow. Metastasis typically does not involve the disc space with erosion of the adjacent vertebral endplates. It usually presents as a lytic/sclerotic lesion in the vertebral body or “winkle owl” sign. These distinguishing features of infection versus metastasis are not certainties. Biopsy is mandatory whenever in doubt or patient is not responded with provisional treatment. The author presents a case with so-called radiological features of spinal tuberculosis infection, which turns out to be a metastatic adenocarcinoma of the lung.

  20. Fulltext Synovial juxtafacet cyst of the spine presenting as radiculopathy
    Nizlan MN, Selvakumar K, Looi LM, Kunasegaran R
    Malaysian Journal of Medicine and Health Sciences, 2005;1(2):131-134.
    Juxtafacet cyst of the spine is a rare occurrence. Reports have described them as synovial cysts; ganglion cysts; extradural cysts as well as degenerative cysts of the spine. Patients may present with radicular pain, motor deficits, sensory disturbances, cauda equina syndrome and even myelopathy. Lumbar juxtafacet cysts may be confused clinically with prolapsed intervertebral discs or other conditions involving nerve root compression such as arachnoid cysts, ependymal cysts, dermoid cysts or teratomatous cysts. In the case of the juxtafacet cyst, surgical excision is usually curative. We report a case of spinal synovial juxtafacet cyst found intraoperatively in a case that was preoperatively diagnosed as prolapsed intervertebral disc. Synovial juxtafacet cyst of the spine should be considered as one of the differential diagnoses in patients, especially in older patients, presenting with nerve root compression.
