    PURPOSE: To introduce a new clinical neck tilt grading and to investigate clinically and radiologically whether neck tilt and shoulder imbalance is the same phenomenon in AIS patients.

    METHODS: 89 AIS Lenke 1 and 2 cases were assessed prospectively using the new clinical neck tilt grading. Shoulder imbalance and neck tilt were correlated with coracoid height difference (CHD), clavicle\rib intersection distance (CRID), clavicle angle (CA), radiographic shoulder height (RSH), T1 tilt and cervical axis.

    RESULTS: Mean age was 17.2 ± 3.8 years old. 66.3 % were Lenke type 1 and 33.7 % were type 2 curves. Strong intraobserver (0.79) and interobserver (0.75) agreement of the clinical neck tilt grading was noted. No significant correlation was observed between clinical neck tilt and shoulder imbalance (0.936). 56.3 % of grade 3 neck tilt, 50.0 % grade 2 neck tilt patients had grade 0 shoulder imbalance. In patients with grade 2 shoulder imbalance, 42.9 % had grade 0, 35.7 % grade 1, 14.3 % grade 2 and only 7.1 % had grade 3 neck tilt. CHD, CRID, CA and RSH correlated with shoulder imbalance. T1 tilt and cervical axis measurements correlated with neck tilt.

    CONCLUSIONS: In conclusion, neck tilt is distinct from shoulder imbalance. Clinical neck tilt has poor correlation with clinical shoulder imbalance. Clinical neck tilt grading correlated with cervical axis and T1 tilt whereas clinical shoulder grading correlated with CHD, RSH CRID and CA.

    The functional outcome of 27 patients (16 males, 11 females) with a proximal humeral fracture was evaluated using the Simple Shoulder Test. Fifteen patients were also assessed using the Constant system. The mean age of the patients was 46.3 years (range 16-90 years) and the mean follow-up was 14 months (range 6-29 months). There were ten 2-part fractures, eight minimally displaced fractures, two 3-part fractures, three 4-part fractures, three 1-part fracture-dislocations and one 3 parts fracture-dislocation. Twenty-four fractures were treated conservatively and 3 surgically. Thirteen patients (48%) regained full function on the simple shoulder test and almost all regained range of movement sufficient for activities of daily living. Six patients were not able to return to their previous job. All patients were pain free at rest and were able to sleep on the affected side comfortably, although 9 patients had pain with activity, even though most pain were mild in nature. The mean Constant scores for the fractured arm and the normal arm were 72.5 points and 91 points respectively. The strength of shoulder abduction was reduced by a mean of 34%. Although the outcome was generally satisfactory, there was nevertheless a statistically significant deterioration of function following the fracture.

    This case history illustrates the real life experience and dilemma of an 80-year-old woman in pursuit of medical care for her left shoulder pain. Points for discussion range from clinical features of Pancoast tumor, importance of pain management, good principles of Family Medicine and Palliative care to ethical issues of conspiracy of silence, limited treatment plan and palliative versus curative radiotherapy treatment without a known biopsy report. This paper provides opportunity for analysis of a real complex clinical situation, application of medical knowledge to problem solving in clinical practice and relevant topics for discussions. (For anonymity sake, the names of patient, doctors, general and private hospitals are not mentioned. The aim of this paper is solely for continuous medical education without any intention to ridicule any party).

    Shoulder arthrodesis is a secondary reconstructive option for patients with brachial plexus injuries requiring a stable shoulder. This study was undertaken to evaluate the clinical and radiological outcomes of shoulder fusion in six patients with flail upper limbs following complete brachial plexus injuries. The shoulder was fused in 30 degrees abduction, 30 degrees internal rotation and 30 degrees flexion via a direct lateral approach by using a 4.5 mm reconstruction plate without bone grafting. The average follow-up was 10.3 months. Radiological union was obtained in all patients. Five patients (83%) had relief of pain after the shoulder fusion. Improvement of function was observed in all patients with a mean improvement of 56.6 degrees (range 30 degrees-75 degrees) and 47.5 degrees (range 30 degrees-60 degrees) active flexion and abduction respectively. One patient developed humeral fracture distal to the plate and the fracture eventually healed with a splint. Successful stable fusion of the shoulder in patients with brachial plexus injuries requires rigid fixation with a single 4.5 mm reconstruction plate, protection of bone healing with a triangular abduction brace for 12 weeks and functional trapezius, levator scapulae, serratus anterior and rhomboid muscles for optimizing the functional result.

    A retrospective study was conducted to determine the incidence of nerve injuries in anterior dislocations of the shoulder and to determine if a neurological examination is routinely performed in such cases. One hundred and fifteen shoulder dislocations in 100 patients (74 males, 26 females; mean age 35+/-18 years) were reviewed. Eighty-seven patients were examined for neurological injuries prior to reduction and 8 of these patients (9.2%) were found to have sustained neurological injuries. Following reduction, neurological examination was performed in 85 patients. Three patients who were not examined initially prior to reduction were subsequently found to have nerve injuries after reduction. Seven patients (7%) were not examined for neurological injury both before and after reduction of the dislocation. Eleven patients were found to have sustained nerve injuries in the final analysis. Axillary nerve injuries were the most common, occurring in 8 patients. In conclusion, nerve injuries are common in shoulder dislocations. The importance of performing and documenting the findings of neurological examination anterior shoulder dislocations needs to be reiterated.

    Acromioclavicular joint (ACJ) dissociation is one of the common injuries affecting adults. The stability of ACJ largely depends on the integrity of acromioclavicular ligament, coracoclavicular ligament, capsule, trapezius muscle and deltoid muscle. The injury has been classified by Rockwood into six types and treatment options can be guided by the classification. TightRope fixation is one of the many surgical procedures available to address acromioclavicular joint separation. It consists of tensioning of a no. 5 Fibrewire suture secured at both ends to low-profile metallic buttons. Despite various advantages of using this technique, complications such as suture cut-out, clavicle fracture and suture failure have been documented. The author presents a case of a type III acromioclavicular joint dissociation treated with TightRope which suture cutout was noted intra-operatively. Decision to amend the fixation using a cut one-third tubular plate as an additional anchor for the metallic button on the clavicle was made. Patient's progress was evaluated using the University of California at Los Angeles Shoulder Score (UCLA Shoulder Score) and significant improvement was noted six months post operatively. We propose this technique as a solution to the encountered problem.

    The incidence of bilateral gleno-humeral joint dislocation is rare, is almost always posterior and is usually caused by sports injuries, epileptic seizures, electrical shock, or electroconvulsive therapy. Bilateral fracture-dislocation is even rarer, with a few cases reported in the literature. We report an unusual case with dislocation of the both glenohumeral joints in opposite direction after a seizure episode, with fracture of greater tuberosity on one side and of the lesser tuberosity on the contralateral side. Although there have been a few reports of bilateral asymmetric fracture dislocations of the shoulder in the past, an injury pattern resembling our case has, to the best of our knowledge, not been described in the literature so far. This report includes a detailed discussion regarding the mechanism of injury in a case of asymmetrical dislocation following a seizure episode. At final follow-up, the patient had healed fractures, painless near normal range of motion with no redislocations.

    A 38-year-old female presented with a 10-month history of right shoulder pain with impingement symptoms. She was diagnosed on magnetic resonance (MR) imaging to have supraspinatus tendon tear and degenerative changes contributing to subacromial impingement. She also had lipoma arborescens of the subacromial-subdeltoid bursa, an uncommon condition in a particularly rare location. Lipoma arborescens is a benign intra-articular condition characterized by lipomatous proliferation of synovium with replacement of subsynovial tissue by mature adipocytes. It is typically a monoarticular process affecting the knee. Due to the presence of pathognomonic fat, diagnosis is usually straightforward with MR as the preferred imaging modality.

    Proximal humerus fracture is a common arm trauma and rarely occurs with vascular injury which however is a serious complication. In this case report, we present a long segment dissection of the axillary and brachial arteries as a rare complication due to fragmented proximal humerus fracture and shoulder dislocation. An 80-year old female patient was seen at the emergency department. Radiograph examination has revealed a fragmented proximal humerus fracture besides dislocation of the head of humerus towards the axillary area. On vascular examination, acute arterial occlusion such as absence of radial and ulnar pulses were observed in her left hand. The patient was immediately taken to the operating room. The dissection included the entire segment approximately 20cm between the distal subclavian artery and the distal brachial artery. This injured segment was removed and a 6mm Polytetrafluroethylene (PTFE) graft with rings was interpositoned between subclavian and brachial arteries. This case is a rarity because of such a significant complication after a small injury. Axillary artery injuries caused by humeral neck fractures are rare but should not be missed by the physician.

    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.

    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.

    BACKGROUND: Results of anatomic shoulder arthroplasty for glenohumeral osteoarthritis with severe glenoid retroversion are unpredictable with a high rate of glenoid loosening. Reverse shoulder arthroplasty (RSA) has been suggested as an alternative, with good early results. We sought to confirm this at longer follow-up (minimum 5 years). The study hypothesis was that early results would endure over time.

    METHODS: We retrospectively reviewed all RSAs performed in 7 centers from 1998 to 2010. The inclusion criteria were primary glenohumeral osteoarthritis with B1, B2, B3, or C glenoid. Forty-nine shoulders in 45 patients fulfilled the criteria. Bone grafting was performed in 16 cases. Clinical outcomes were evaluated with the Constant score (CS) and shoulder range of motion.

    RESULTS: The mean total CS increased from 30 preoperatively to 68 points (P < .001) with significant improvements in all the subsections of the CS and range of motion. Scapular notching was observed in 20 shoulders (43%), grade 1 in 5 (11%), grade 2 in 7 (15%), grade 3 in 5 (11%), and grade 4 in 3 (6%). The glenoid bone graft healed in all the shoulders. Partial inferior lysis of the bone graft was present in 8 cases (50%). Scapular notching and glenoid bone graft resorption had no influence on the CS (P = .147 and P = .798).

    CONCLUSION: RSA for the treatment of primary glenohumeral osteoarthritis in patients with posterior glenoid deficiency and humeral subluxation without rotator cuff insufficiency resulted in excellent clinical outcomes at a minimum of 5 years of follow-up.

    We describe the clinical presentation, investigation and management of an eventually fatal case of hypercalcemic crisis due to primary hyperparathyridism (PHPT). A 60 year-old lady with history of urolithiasis presented with worsening generalized bone pain, spinal scoliosis and a limp. Laboratory data showed hypercalcemia and raised alkaline phosphatase. Left hip x-ray revealed a subcapital femoral neck fracture. Intact parathyroid hormone was elevated, 187.6 pmol/L (1.6 – 6.9) and ultrasound showed an enlarged right parathyroid gland. Despite initial reduction of serum calcium with saline infusion and multiple doses of intravenous pamidronate, her calcium increased to 4.14 mmol/L a week following application of Buck’s traction for persistent left hip pain. She succumbed eventually with serum calcium peaking at 6.28 mmol/L despite multiple therapeutic interventions.

    Validity test is important during the development of ergonomics measurement. Failure to conduct validity tests will result in the measurement method being developed to be incapable of providing reliable ergonomics measurements. The objective of this study is to conduct validity test on the simple method ergonomics measurement which was developed. The method named Simple Ergonomics Risks Assessment (SERA). Content validity test and criterion validity test were conducted. The content validity test consists of 6 ergonomics experts who actively provide inputs and positive feedbacks to improve the measurement method being developed. Meanwhile, the criterion validity test involves data collection of complaints on body parts among oil palm workers which were derived from Nordic Musculoskeletal Questionnaire (NMQ) and ergonomics risk assessment scores obtained from SERA. Both findings were tested with the Chi-square test to explore possible relations between the two findings. Results from the test conducted showed that there are significant relations in the scores of neck posture; hip, right and left shoulder, right and left wrists and the right hand associated with fresh fruit bunch (FFB) harvesting activities. In the loose fruits collection, the Chi-square test showed significant relations in the scores of neck posture, hip, right and left shoulders, right wrist, right arm and the left hand. However, there are body parts such as the legs which showed no significant relation. More tests should be conducted to further explore the validity of the method being developed. Findings from both validity tests show that SERA were verified by the experts and tested with validated method so that it is valid to be applied in the future.

    The aim of this descriotive study is to determine the incidence of injuries among recreational badminton players. We evaluated 86 recreational badminton players in the city of Malacca; 35 were excluded for fitting the exclusion criteria. The average recreational badminton player was 36.13 years old and had been playing badminton for the past 17.84 years at a frequency of 2.11 times per week. 39.21% of the recreational badminton players complained of recent injuries in relation to playing badminton. Our data showed that the most common injury sustained by recreational badminton players was pain and stiffness at the shoulder joint. None of the injuries sustained by the players in our data were serious enough to warrant any form of surgical intervention. We conclude that badminton is a sport of relatively low risk and that the majority of related injuries were chronic overuse injuries.

    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.

    The purpose of this study were to compare the emergence profiles of crowns with their contralateral tooth, in vitro, and to determine if there is any association between the design of tooth preparations and the resultant emergence profile. 50 working models used for single crown construction were examined. Measurements of the faciolingual width of the crowns and contralateral teeth were taken using digital calipers. Internal line angles and the margin width of dies and the emergence profile of the corresponding crowns were measured from longitudinally sectioned polyvinylsiloxane indices mounted on a flat-bed scanner using image analysis software. Using Students t tests, no statistically significant differences (p>0.05) were found for shoulder width (mean 0.94 ± 0.23mm), internal line angle (mean 105.83 ± 13.57°) or emergence profiles (28.56 ± 12.95°) in the different (anterior, premolar or molar) preparations or crowns. The mean emergence profiles for all crowns was statistically significantly greater (p
