    Objectives: This study aimed to determine isokinetic profiles of rotator cuff muscle strength and power in adolescent state-level weightlifters.

    Methods: Nineteen young state-level weightlifters performed concentric strength tests of the upper limbs using an isokinetic dynamometer. Peak torque/body weight was measured for each weightlifter in dominant and non-dominant limbs.

    Results: Peak torque/body weight was significantly different in external rotation (p  0.05). Time to peak torque in external rotation was less in the dominant than in the non-dominant limb. However, opposite results were obtained in external rotation, whereby time to peak torque was longer in the dominant limb compared to the non-dominant limb. Similarly, no significant difference was found between dominant and non-dominant limbs in terms of average power (p > 0.05).

    Conclusions: The findings of this study may help in establishing potential imbalance in variables of muscular contractions between dominant and non-dominant limbs of weightlifters. This may help to maximise performance and minimise potential shoulder injury.

    ‘Nasi kandar’ is defined as boiled white rice placed inside a wooden basket and carried on the shoulder using a pole. The rice is served with a variety of pairing dishes that are usually fried, curried or boiled. The tradition of carrying rice and pairing dishes on the shoulder began to die out in the 20th century as seller resorted to a more conventional way of selling ‘nasi kandar’. The ‘nasi kandar’ business in Malaysia has evolved from being sold as a street food into a multi-million dollar franchise business rivalling the fast food business. It is available 24 hours and enjoyed by Malaysians from all walks of life. This study aims to compare ‘nasi kandar’ eating pattern among patrons in the Klang Valley and Penang. Three hundred sets of questionnaires were answered and collected. Data from the questionnaires were analyzed in PASW 18.0 using descriptive statistics and chi-square test for association. Klang Valley patrons (72%) would consume ‘nasi kandar’ once a week. More than half (53.3%) of the patrons from Penang consumed ‘nasi kandar’ more than twice a week. A significant relationship exists between patron’s region and frequency of ‘nasi kandar’ consumption where p = <0.0001 and r = 0.277. A significant but moderate relationship between patron’s region and consumption of ‘nasi kandar’ during breakfast (p = <0.001, r = 0.250), lunch (p = <0.0001, r = 264) and dinner (p = <0.0001, r = 0.336). Patrons in Penang consumed ‘nasi kandar’ more often than their Klang Valley counterparts. Klang Valley patrons were more particular than Penang patrons when it comes to cleanliness, menu pricing, friendly service, air-condition and separate smoking area. Klang Valley patrons tend to consume more chicken based dishes while Penang patrons tend to consume more meat, fish, and squid based dishes.

    HyperDSC™(fast scan rate) was used to study the melting behavior of canola (CLO), sunflower (SFO), palm olein (PO), rice bran oils (RBO), and cocoa butter (CB), and was compared to the melting behaviors using conventional DSC. There was an increase in sensitivity with increase in scan rate. Slow scan rate (5 to 20C/min) gave low sensitivity, which increased when the scan rates were increased to 50, 100 and 200C/min. Peak resolution was affected by scan rate depending on the sample weight. Increase in the size of sample coupled with the use of fast scan rate decreased the peak resolution. Generally small sample sizes gave better peak resolution. Results of the effect of scan rate on glass transition (Tg) shows that Tg, which is a weak transition especially in crystalline and low amorphous materials was not detected using conventional scan rates (5 to 20oC/min). It was however detected using of hyperDSC™ scan rates (100 to 200oC/min). Increasing the scan rate resulted in an increase in the peak temperature and the elimination of shoulder peaks, which were caused due to the polymorphic behavior of the triacylglycerols in the oils. The increase in peak temperature caused a shift in the peak position towards a higher temperature value. There is a positive correlation between the peak temperature and scan rate. The correlation coefficients (r) for CLO, SFO, PO, RBO and CB were 0.96, 0.95, 0.97, 0.96 and 0.96 respectively.

    Ergonomic is important in classroom. Sitting for protracted period in class may lead students to develop musculoskeletal disorders. Their physical health and performance in the class may increase by designing school furniture that match with human body. In Malaysia, there is a lack of ergonomic assessment for school environment especially in urban areas. The aim of this study is to determine the mismatch between the furniture dimension and anthropometric parameters among primary school children in Putrajaya. This is a cross-sectional study which involved 100, Year 1 and Year 6 primary school students randomly selected in Putrajaya. Five anthropometric measurements (popliteal height, buttock popliteal length, elbow height, shoulder height (sitting), hip breadth) as well as five furniture dimensions (seat height, seat depth, seat width, backrest height and seat to desk height) were measured. Instrument used is Martin type anthropometer set, SECA body meter, and SECA weighing scale. Calculation for determining mismatch between the furniture and anthropometric measures were calculated using a standard mismatch formula. There was 100% mismatch for seat height, seat depth, and seat to seat to desk height for Year 1. As for Year 6, mismatch was reported 100% for backrest height and seat to desk height. There were significance difference for parameters of popliteal height between Year 1 and Year 6 and between male and female of Year 1. There was a presence of mismatch between furniture dimension and children anthropometric measurement. Proposed dimension of furniture shows decrease in percentage of mismatch for the most parameter of anthropometric measurement.

    Post-stroke shoulder pain is associated with either a peripheral or central pathology. However, most of the time, it is challenging to establish a cause-and-effect relationship between the suggested pathology and shoulder pain reported. We report a 66 year-old man who developed a right hemiplegic shoulder pain two months post stroke with initial investigations suggestive of peripheral pathologies. Pharmacological and non-pharmacological treatment did not improve his shoulder pain. Later he developed complex regional pain syndrome (CRPS) of the right hand and the initial shoulder pain subsequently relieved following resolution of the CRPS.

    This study was conducted to investigate i) while the shoulder was in 180° of flexion and the elbow extended, which of the forearm position (supination, pronation and neutral) can generate the greatest handgrip strength, ii) is there any correlation of the handgrip strength between the dominant hand (right hand) and non-dominant hand (left hand) in each forearm position, and iii) will the dominant hand possessed 10% higher handgrip strength than the non-dominant hand. 100 right handed sedentary active students age 22.20 years old (± 1.03), height 172.83 cm (± 6.37), body mass 68.87 (± 11.52) and grip position 3.77 (± 0.77) were recruited in this study. The result indicated that for both the dominant and non-dominant hand, when the shoulder is in 180˚ flexion of the body with the elbow extended, the greatest grip strength was obtained when the forearm was in neutral position followed by pronation and supination position. Post Hoc analysis showed that for both dominant hand and non-dominant hand, pronation and supination forearm position produced greater strength score compared to supination forearm position (p0.05). In all forearm position, participants were shown to produced significantly greater strength in their dominant hand and all the scores were more than 10% greater compared to when using non-dominant hand. Positive relationships were also found for the strength score between dominant hand and non-dominant hand. As the conclusion, different shoulder, elbow and forearm position can affect handgrip strength.

    OBJECTIVE: This study examined the relationships between psychosocial work factors and risk of WRMSDs among public hospital nurses in the Klang Valley, Malaysia.

    METHODS: We conducted a cross-sectional study among 660 public hospital nurses. A self-administered questionnaire was used to collect data on the occurrence of WRMSDs according to body regions, socio-demographic profiles, occupational information and psychosocial risk factors. 468 questionnaires were returned (response rate of 71%), and 376 questionnaires qualified for subsequent analysis. Univariate analyses were applied to test for mean and categorical differences across the WRMSDs; multiple logistic regression was applied to predict WRMSDs based on the Job Strain Model's psychosocial risk factors.

    RESULTS: Over two thirds of the sample of nurses experienced discomfort or pain in at least one site of the musculoskeletal system within the last year. The neck was the most prevalent site (48.94%), followed by the feet (47.20%), the upper back (40.69%) and the lower back (35.28%). More than 50% of the nurses complained of having discomfort in region one (neck, shoulders and upperback) and region four (hips, knees, ankles, and feet). The results also revealed that psychological job demands, job strain and iso-strain ratio demonstrated statistically significant mean differences (p shoulders and upper back) and region 4 (hips, knees, ankles, and feet). All demographic variables except for years of employment were statistically and significantly associated with WRMSDs (p

    STUDY DESIGN: Retrospective review of prospective data.

    OBJECTIVE: To determine if surgically leveling the upper thoracic spine in patients with adolescent idiopathic scoliosis results in level shoulders postoperatively.

    SUMMARY OF BACKGROUND DATA: Research has shown that preoperatively tilted proximal ribs and T1 tilt are more correlated with trapezial prominence than with clavicle angle.

    METHODS: Prospectively collected Lenke 1 and 2 cases from a single center were reviewed. Clinical shoulder imbalance was measured from 2-year postoperative clinical photos. Lateral shoulder imbalance was assessed utilizing clavicle angle. Medial imbalance was assessed with trapezial angle (TA), and trapezial area ratio (TAR). First rib angle, T1 tilt, and upper thoracic curve were measured from 2-year radiographs. Angular measurements were considered level if ≤ 3° of zero. TAR was considered level if ≤ 1 standard deviation of the natural log of the ratio. Upper thoracic Cobb at 2-years was categorized as at or below the mean value (≤ 14°) versus above the mean.

    RESULTS: Eighty-four patients were identified. There was no significant difference in the percentage of patients with a level clavicle angle or TAR based on first rib being level, T1 tilt being level, or upper thoracic Cobb being at/below versus above the mean (P shoulders or clavicles. Trapezial prominence was impacted by leveling T1 and the first rib and by minimizing the upper thoracic curve. How to achieve laterally balanced shoulders postoperatively remains unclear.

    This position development conference (PDC) Task Force examined the assessment of bone status in orthopedic surgery patients. Key questions included which orthopedic surgery patients should be evaluated for poor bone health prior to surgery and which subsets of patients are at high risk for poor bone health and adverse outcomes. Second, the reliability and validity of using bone densitometry techniques and measurement of specific geometries around the hip and knee before and after arthroplasty was determined. Finally, the use of computed tomography (CT) attenuation coefficients (Hounsfield units) to estimate bone quality at anatomic locations where orthopedic surgery is performed including femur, tibia, shoulder, wrist, and ankle were reviewed. The literature review identified 665 articles of which 198 met inclusion exclusion criteria and were selected based on reporting of methodology, reliability, or validity results. We recommend that the orthopedic surgeon be aware of established ISCD guidelines for determining who should have additional screening for osteoporosis. Patients with inflammatory arthritis, chronic corticosteroid use, chronic renal disease, and those with history of fracture after age 50 are at high risk of osteoporosis and adverse events from surgery and should have dual energy X-ray absorptiometry (DXA) screening before surgery. In addition to standard DXA, bone mineral density (BMD) measurement along the femur and proximal tibia is reliable and valid around implants and can provide valuable information regarding bone remodeling and identification of loosening. Attention to positioning, selection of regions of interest, and use of special techniques and software is required. Plain radiographs and CT provide simple, reliable methods to classify the shape of the proximal femur and to predict osteoporosis; these include the Dorr Classification, Cortical Index, and critical thickness. Correlation of these indices to central BMD is moderate to good. Many patients undergoing orthopedic surgery have had preoperative CT which can be utilized to assess regional quality of bone. The simplest method available on most picture archiving and communications systems is to simply measure a regions of interest and determine the mean Hounsfield units. This method has excellent reliability throughout the skeleton and has moderate correlation to DXA based on BMD. The prediction of outcome and correlation to mechanical strength of fixation of a screw or implant is unknown.

    The management of post-radiation wound breakdown over the posterior cervico thoracic region can be a challenging task for a surgeon. The aim of the treatment is to produce a well vascularized and a low tensile flap which will close a large defect. We describe the use of the lower trapezius flap to reconstruct the wound breakdown and to obtain stable tissue coverage in a patient with post- radiation necrosis. This flap minimizes the disruption of the scapula-thoracic function while preserving the range of movement over the shoulder. From the literature review, it was noted that the dorsal scapular artery (DSA) and transverse cervical artery (TCA) aid in the blood supply to the trapezius muscle and prevent local necrosis during rotation of the flap. The trapezius flap is widely accepted because of the minor donor site morbidity, large arc of rotation and adequate blood supply.

    A 16-year-old Malay boy presented to Kota Bharu Health Care Centre, Kelantan, with left shoulder pain after sustaining a fall. On further history taking, it was noted that the pain preceded the fall by 1 month. The early changes of osteosarcoma were visible on an X-ray during the initial presentation; however, this was missed by the primary care doctors. Three months later, the patient presented with persistent pain in the left shoulder and was diagnosed with osteosarcoma.

    Introduction: The purpose of this study is to identify the incidence of clavicle fractures in newborn
    associated with fetal, maternal and process of deliveries in Kuantan General Hospital from June 2012 until
    January 2014. This study is to determine epidemiological data of clavicle fractures, maternal and baby risk
    factors associated with clavicle fractures of newborn and its’ outcome.

    Methods: This is a prospective
    study. 13 patients were identified to fulfill the inclusion criteria of the study. The data of
    sociodemographic, associated fetal and maternal risk factors and the outcomes were recorded using
    proforma. The statistical data analysis was done using SPSS 12.0.

    Results: Out of 20,257 live births at our
    centre during the study period, 13 infants were diagnosed to have clavicle fractures, giving an incidence of
    0.64 per 1000 live births. There were 5 (38.5%) left, 7 (53.8%) right and one (7.7%) bilateral fracture. All
    fractures located at the mid shaft of the clavicle and none have associated brachial plexus injuries. All
    infants were delivered through vaginal delivery (61.5%); five through assisted delivery (instrumental); 2
    (15.4%) forcep and 3 (23.1%) vacuum. Two of the babies developed shoulder dystocia. The average birth
    weight was 3371 grams (SD 0.269) and mean gestational age was 38.7 weeks (SD 1.16). Five of the mothers
    (38.5%) were primigravida and eight (61.5%) were multigravida in which,7 (53.8%)were healthy without
    other co-morbidty, 5 (38.5%) having gestational diabetis and one (7.7%) hypertension. The average maternal
    weight was 62.0 kg and height 1.58 metres with average BMI of 24.16 (3.29SD). All eventually had a
    complete recovery at 6 weeks with clinical and radiological evident of fracture union.

    Conclusions: In
    conclusion, all patients with clavicle fractures were found following vaginal delivery. There were no
    associations between neonatal clavicle fractures with maternal or baby risk factors. All fractures healed
    without any complications.

    OBJECTIVE: The main aim of the study was to analyze the outcomes of clavicle fractures in adults treated non-surgically and to evaluate the clinical effects of displacement, fracture patterns, fracture location, fracture comminution, shortening and fracture union on shoulder function.

    METHODS: Seventy clavicle fractures were non-surgically treated in the Orthopedics Department at the Tuanku Ja'afar General Hospital, a tertiary care hospital in Seremban, Malaysia, an average of six months after injury. The clavicle fractures were treated conservatively with an arm sling and a figure-eight splint for three weeks. No attempt was made to reduce displaced fractures, and the patients were allowed immediate free-shoulder mobilization, as tolerated. They were prospectively evaluated clinically and radiographically. Shoulder function was evaluated using the Constant scoring technique.

    RESULTS: There were statistically significant functional outcome impairments in non-surgically treated clavicle fractures that correlated with the fracture type (comminution), the fracture displacement (21 mm or more), shortening (15 mm or more) and the fracture union (malunion).

    CONCLUSION: This article reveals the need for surgical intervention to treat clavicle fractures and improve shoulder functional outcomes.

    Bilateral clavicle fractures are not frequently seen. To treat these injuries surgically or non-surgically is still a debatable issue. Implant option for surgical management is also in doubt. We would like to share our experience in treating a patient with bilateral clavicle fracture surgically. He had excellent outcomes in terms of function and radiology. Surgical option for bilateral clavicle fractures promises excellent outcome in terms of early rehabilitation and return in function.

    BACKGROUND: Shoulder pain and stiffness affects at least one-quarter of the Australian population, with the primary care physician seeing 95% of these patients. Idiopathic frozen shoulder affects >250,000 Australians, making it a significant burden on both the individual and society. The primary care physician plays a major part in recognising the condition and formulating an evidence-based management plan in conjunction with the physiotherapist.

    OBJECTIVE: This article provides the reader with an understanding of the natural history, pathophysiology, phases and clinical features of idiopathic frozen shoulder. It also outlines patients at risk of developing idiopathic frozen shoulder and addresses an evidence-based conservative approach to the management of this condition.

    DISCUSSION: The primary care physician plays a pivotal part in the identification and management of idiopathic frozen shoulder, with the vast majority of patients responding to conservative management. A shared care approach with a skilled physiotherapist is essential.

    STUDY DESIGN: Retrospective study.

    OBJECTIVE: The primary objective of this study was to assess the conformity of the radiological neck and shoulder balance parameters throughout a follow-up period of more than 2 years.

    SUMMARY OF BACKGROUND DATA: Postoperative shoulder and neck imbalance are undesirable features among Adolescent Idiopathic Scoliosis (AIS) patients who underwent Posterior Spinal Fusion (PSF). There are many clinical and radiological parameters used to assess this clinical outcome. However, we do not know whether these radiological parameters conform throughout the entire follow-up period.

    METHODS: This was a retrospective study done in a single academic institution. Inclusion criteria were patients with scoliosis who underwent posterior instrumented spinal fusion with pedicle screw fixation and attended all scheduled follow-ups for at least 24 months postoperatively. Radiological shoulder parameters were measured from both preoperative antero-posterior (AP) and postoperative AP radiographs. Lateral shoulder parameters were: Radiographic Shoulder Height (RSH), Clavicle angle (Cla-A), Clavicle-Rib Intersection Difference (CRID) and Coracoid Height Difference (CHD). Medial shoulder and neck parameters were: T1 tilt and Cervical Axis (CA).

    RESULTS: The radiographs of 50 patients who had surgery done from November 2013 to November 2015 were analyzed. Mean age of this cohort was 16.3 ± 7.0 years. There were 38 (76%) female patients and 12 (24%) male patients. Mean final follow-up was 38.6 ± 5.8 months. When conformity assessment of the radiological parameter using the interclass coefficient correlation (ICC) was done, we found that all parameters had significant correlation (p shoulder and neck balance parameters studied were conformed and suitable to be used to assess the patient postoperatively. Amongst these radiological parameters, T1 tilt followed by CA recorded to be the most reliable parameters over time.

    Brachial plexus injuries with intact yet flail limb presents with problems of persistent neuropathic pain and recurrent shoulder dislocations, that render the flail limb a damn nuisance. As treating surgeons, we are faced with the dilemma of offering treatment options, bearing in mind the patient's functional status and expectations. We present a case of a 55-year old housewife with complete brachial plexus injury begging for surgical amputation of her flail limb, 6 years post-injury. Here we discuss the outcome of transhumeral amputation and the possibility of offering early rather than delayed amputations in this group of patients.
