    PURPOSE: This study aims to determine the prevalence of malnutrition among orthopaedic oncology patients with malignant tumour during preoperative period.

    METHODS: This is a prospective observational study involving patients from the orthopaedic oncology unit who were undergoing surgery. They were assessed with Patient Generated Subjective Global Assessment (PG-SGA), Malnutrition Screening Tool (MST) and 3-minute Nutritional Screening (3MinNS) questionnaires. Anthropometric data such as body mass index, mid upper arm circumference (MUAC) and blood parameters such as serum albumin, total lymphocyte count and haemoglobin were also investigated. Patients were then followed up for 3 months. Post-operative complications were divided into infectious and non-infectious groups. Length of stay and unplanned readmission were also documented.

    RESULTS: Prevalence of malnutrition ranged from 13.3% to 45.8% under different nutritional assessment methods. Patients who were determined as malnourished were significantly associated with both infectious and non-infectious post-operative complications ( p < 0.001). PG-SGA and 3MinNS values were also significant in univariate and multivariate analysis, respectively. Low serum albumin (<35 g/L) was associated with post-operative infectious complications, especially surgical site infection ( p < 0.001), prolonged hospital stay ( p = 0.009) and unplanned readmission ( p = 0.017). 3MinNS and Charlson Comorbidity Index were predictive of non-infectious complications, whereas serum albumin and the presence of metastasis were predictive of infectious complications.

    CONCLUSION: This pilot study of patients with soft tissue and bone sarcoma of upper and lower limbs showed that malnutrition is a significant independent factor related to infectious and non-infectious complications which leads to unplanned readmission and prolonged length of stay. Periodic screening using the PG-SGA or 3MinNS questionnaires, MUAC and evaluation of serum albumin levels is recommended during clinic session and pre-surgery assessment rounds to identify those predisposed to malnutrition and help in reducing incidence of post-operative complications.

    PURPOSE: To describe the reduction technique of thoracolumbar burst fracture using percutaneous monoaxial screws and its radiological outcomes compared to polyaxial screws.

    METHODS: All surgeries were performed by minimally invasive technique with either percutaneous monoaxial or percutaneous polyaxial screws inserted at adjacent fracture levels perpendicular to both superior end plates. Fracture reduction is achieved with adequate rod contouring and distraction maneuver. Radiological parameters were measured during preoperation, postoperation, and follow-up.

    RESULTS: A total of 21 patients were included. Eleven patients were performed with monoaxial pedicle screws and 10 patients performed with polyaxial pedicle screws. Based on AO thoracolumbar classification system, 10 patients in the monoaxial group had A3 fracture type and 1 had A4. In the polyaxial group, six patients had A3 and four patients had A4. Total correction of anterior vertebral height (AVH) ratio was 0.30 ± 0.10 and 0.08 ± 0.07 in monoaxial and polyaxial groups, respectively (p < 0.001). Total correction of posterior vertebral height (PVH) ratio was 0.11 ± 0.05 and 0.02 ± 0.02 in monoaxial and polyaxial groups, respectively (p < 0.001). Monoaxial group achieved more correction of 13° (62.6%) in local kyphotic angle compared to 8.2° (48.0%) in polyaxial group. Similarly, in regional kyphotic angle, 16.5° (103.1%) in the monoaxial group and 8.1° (76.4%) in the polyaxial group were achieved.

    CONCLUSIONS: Monoaxial percutaneous pedicle screws inserted at adjacent fracture levels provided significantly better fracture reduction compared to polyaxial screws in thoracolumbar fractures.

    INTRODUCTION: Management of osteosarcoma has evolved considerably for the past two decades and there have been changes of practices especially pertaining to chemotherapy regime. This is a review of our cases in the past 15 years.

    METHOD: This is a retrospective survival analysis study of 128 patients treated at University Malaya Medical Centre (UMMC) from 1997 to 2011.

    RESULTS: There were 80 (62.5%) male and 48 (37.5%) female patients with the median age being 15 (5-59). Majority had osteosarcoma of extremities (94.5%). More than 60% patients developed metastasis throughout the course of treatment with 39% presenting with lung metastasis. Osteoblastic osteosarcoma was the commonest subtype (65.6%). Of the 109 patients treated surgically, 84 patients (65.6%) underwent limb salvage surgery while the rest underwent amputation. Seventy-one per cent of patients completed treatment with local recurrence rate of 22.7%. The 5-year and 10-year survival rates were 56.31% (95% CI: 46.20, 65.24) and 22.33% (95% CI: 14.86, 30.76), respectively. The 5-year event-free survival was 52.94% (95% CI: 41.83, 62.87). In multivariate analysis, the independent prognostic factors were presence of metastasis and completion of treatment for both 5-year and 10-year overall survival. Good histological response was only significant for multivariate analysis at 5 years. Patients with metastasis had a hazard ratio of 20.4 at 5 years and 3.26 at 10 years.

    CONCLUSION: Overall survival rate for osteosarcoma patients at our centre was comparably higher than other centres in the region. Two independent risk factors for survival are metastatic status and completion of treatment. A standardized chemotherapy regime is essential for long-term survival.

    PURPOSE: A recent 3-month randomized, open-label controlled trial found that the intra-articular hyaluronic acid injection (GO-ON®) given as a single dose of 5 mL is as effective and safe as three repeated doses of 2.5 mL in patients with knee osteoarthritis. However, the information on the long-term efficacy and economic implications of the single-dose regimen is still limited. Hence, this follow-up study was designed to compare the effectiveness and costs of the two regimens 12 months following the treatment.

    METHODS: All the 127 patients, who received either three repeated doses (n = 64) or a single dose (n = 63) of GO-ON in the previous trial, were followed up in month 12 following the treatment. The effectiveness of both the regimens was assessed using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and the mean WOMAC scores were compared with those recorded at the baseline and in month 3. Additionally, the total treatment costs of the two regimens, taking account of both direct and indirect costs, were computed and compared.

    RESULTS: A total of 125 patients (98.4%) completed the assessment. Despite the reduction of the overall mean WOMAC score from 39.24 to 19.93 (p < 0.001) in the first 3 months following the treatment with GO-ON, no further changes were observed up to month 12 (p > 0.95). In the meantime, the two regimens did not differ in the mean WOMAC scores (p = 0.749) and in the subscale scores for pain (p = 0.970), stiffness (p = 0.526), and physical functioning (p = 0.667) in month 12. The cost for single-dose injection was found to be approximately 30% lower compared to the repeated doses.

    CONCLUSION: These findings indicate that the single larger dose of GO-ON is as effective as the repeated doses over 12 months, and yet the total treatment cost is lowered.

    The 'all-inside' meniscus repair is extremely useful technique in addressing tears at the far posterior horn of meniscus. However, this procedure may place the popliteal neurovascular bundle at risk of injury. The purpose of this study was to evaluate the risk of popliteal artery injury by the trajectory of anchor delivery instruments inserted through standard knee arthroscopic portals for the repair of the far posterior horn of meniscus tears. Standard arthroscopic portals were marked on five human cadaveric knees which were subsequently disarticulated. Axial photographs were taken after marking the 5 10, and 15 mm points from the meniscal root on the posterior horns of the menisci. The unsafe zones for meniscus repair at each of these points were identified on the photographs of knees by first drawing two lines from the edges of the popliteal artery and crossing at the respective points at the posterior horns. The points at which these lines meet a circular protractor applied to the center of each meniscus in the knee photograph were recorded as a range. The range signifies the unsafe zone for each respective point on the posterior horn of meniscus. The anterolateral arthroscopic portal fell within the unsafe zone of the 5 mm point on the posterior horn of lateral meniscus in three of the five knees and within the unsafe zone of the 10 mm point on the posterior horn of lateral meniscus in another two knees. A cautious approach should be practiced during the repair of tears located at these two points. None of the other points' unsafe zones (lateral 15 mm, medial 5 mm, 10 mm and 15 mm points) coincided with the ipsilateral portal sites. Level of evidence 5 (Human cadaveric study).

    PURPOSE: Bone cement is commonly used as a void filler for bone defects. Antibiotics can be added to bone cement to increase local drug delivery in eradicating infection. After antibiotic elution, nonbiodegradable material becomes an undesirable agent. The purpose of this study was to evaluate effects of addition of vancomycin on the compressive strength of injectable synthetic bone substitute, JectOS®. JectOS, a partially biodegradable cement that over time dissolves and is replaced by bone, could be potentially used as a biodegradable antibiotic carrier.

    METHODS: Vancomycin at various concentrations was added to JectOS and polymethyl methacrylate (PMMA). Then, the cement was molded into standardized dimensions for in vitro testing. Cylindrical vancomycin-JectOS samples were subjected to compressive strength. The results obtained were compared to PMMA-vancomycin compressive strength data attained from historical controls. The zone of inhibition was carried out using vancomycin-JectOS and vancomycin-PMMA disk on methicillin-resistant strain culture agar.

    RESULTS: With the addition of 2.5%, 5%, and 10% vancomycin, the average compressive strengths reduced to 8.01 ± 0.95 MPa (24.6%), 7.52 ± 0.71 MPa (29.2%), and 7.23 ± 1.34 MPa (31.9%). Addition of vancomycin significantly weakened biomechanical properties of JectOS, but there was no significant difference in the compressive strength at increasing concentrations. The average diameters of zone of inhibition for JectOS-vancomycin were 24.7 ± 1.44 (2.5%) mm, 25.9 ± 0.85 mm (5%), and 26.8 ± 1.81 mm (10%), which outperformed PMMA.

    CONCLUSION: JectOS has poor mechanical performance but superior elution property. JectOS-vancomycin cement is suitable as a void filler delivering high local concentration of vancomycin. We recommended using it for contained bone defects that do not require mechanical strength.

    BACKGROUND:: Trigger finger release utilizing wide-awake local anesthesia no tourniquet (WALANT) usage in extremity surgery is not widely used in our setting due to the possibility of necrosis. Usage of a tourniquet is generally acceptable for providing surgical field hemostasis. We evaluate hemostasis score, surgical field visibility, onset and duration of anesthesia, pain score, and the duration of surgery and potential side effects of WALANT.

    METHODS:: Eighty-six patients scheduled for trigger finger release between July 2016 and December 2017 were randomized into a control group (1% lignocaine and 8.4% sodium bicarbonate with arm tourniquet; given 10 min prior to procedure) and an intervention group (1% lignocaine, 1:100,000 of adrenaline and 8.4% sodium bicarbonate; given 30 min prior to procedure), with a total of 4 ml of solution injected around the A1 pulley. The onset of anesthesia and pain score upon injection of the first 1 ml were recorded. After the procedure, the surgeon rated for the hemostasis score (1-10: 1 as no bleeding and 10 being profuse bleeding). Duration of surgery and return of sensation were recorded.

    RESULTS:: Hemostasis score was grouped into visibility score as 1-3: good, 4-6: moderate, and 7-10: poor. The intervention group (with adrenaline) had a 74% of good surgical field visibility compared to 44% from the controlled group (without adrenaline; p < 0.05). Duration of anesthesia was longer in the intervention group (with adrenaline), with a 2.77-h difference.

    CONCLUSION:: WALANT provides excellent surgical field visibility and is safe and on par with conventional methods but without the usage of a tourniquet and its associated discomfort.

    PURPOSE: Ensuring compliance to treatment protocol, especially regular visit to treating facility, is an important aspect of clubfoot management. However, the factors affecting compliance to follow-up schedule are myriad.

    METHODS: A cross-sectional study was undertaken among caregivers of clubfoot patients from a tertiary referral clubfoot clinic in a developing country. Hospital records were reviewed to collect demographic data and subjects were classified as either "regular" or "irregular" if they missed ≤3 and >3 scheduled hospital visits, respectively. Various factors that could affect compliance such as family size, number of children, literacy of caregiver, occupation of breadwinner, and time taken to travel to hospital were studied. Caregivers were probed regarding the reason for their irregularity.

    RESULTS: A total of 238 patients were included, of which 138 formed the "regular" group and the rest 100 formed the "irregular" group. Patients in the regular group were significantly younger (mean age 43.8 months) compared to the irregular group (59.8 months; p = 0.001). The mean follow-up period in the regular group was 28.1 months and in the irregular group was 33.8 months. On univariate analysis, age, duration of follow-up, and transport duration were found to be significant between the two groups. However, multivariate analysis revealed that female children with clubfoot are more likely to be irregular as compared to males ( p = 0.038).

    CONCLUSION: In a developing country setting, higher age and being a female child are associated with irregularity to hospital visit protocol. At clubfoot clinics, identifying these children and counseling their caregivers might improve compliance.

    PURPOSE: To analyze the incidence, pattern, and contributing factors of pelvic obliquity among Adolescent Idiopathic Scoliosis (AIS) patients who will undergo surgery.

    METHODS: In total, 311 patients underwent erect whole spine anteroposterior, lateral and lower limb axis films. Radiographic measurements included Transilium Pelvic Height Difference (TPHD; mm), Hip Abduction-Adduction angle (H/Abd-Add; °), Lower limb Length Discrepancy (LLD; mm), and Pelvic Hypoplasia (PH angle; °). The incidence and severity of pelvic obliquity were stratified to Lenke curve subtypes in 311 patients. The causes of pelvic obliquity were analyzed in 57 patients with TPHD ≥10 mm.

    RESULTS: The mean Cobb angle was 64.0 ± 17.2°. Sixty-nine patients had a TPHD of 0 mm (22.2%). The TPHD was <5 mm in 134 (43.0%) patients, 5-9 mm in 104 (33.4%) patients, 10-14 mm in 52 (16.7%) patients, 15-19 mm in 19 (6.1%) patients, and ≥20 mm in only 2 (0.6%) patients. There was a significant difference between the Lenke curve types in terms of TPHD (p = 0.002). L6 curve types had the highest TPHD of 9.0 ± 6.3 mm followed by L5 curves, which had a TPHD of 7.1 ± 4.8 mm. In all, 44.2% of L1 curves and 50.0% of L2 curves had positive TPHD compared to 66.7% of L5 curves and 74.1% of L6 curves which had negative TPHD. 33.3% and 24.6% of pelvic obliquity were attributed to PH and LLD, respectively, whereas 10.5% of cases were attributed to H/Abd-Add positioning.

    CONCLUSIONS: 76.4% of AIS cases had pelvic obliquity <10 mm; 44.2% of L1 curves and 50.0% of L2 curves had a lower right hemipelvis compared to 66.7% of L5 curves and 74.1% of L6 curves, which had a higher right hemipelvis. Among patients with pelvic obliquity ≥10 mm, 33.3% were attributed to PH, whereas 24.6% were attributed to LLD.

    PURPOSE: Inflammation plays a major role in tumour development, progression and metastasis. Multiple inflammatory markers such as absolute lymphocyte count, neutrophil-lymphocyte ratio (NLR), lymphocyte-monocyte ratio (LMR) and platelet-lymphocyte ratio have been discovered as prognostic markers for various malignancies. We investigate preoperative lymphocyte count and other cell count ratios and their relation to survival and prognosis of sarcoma patients after surgery.

    METHODS: A total of 142 patients from the Orthopaedics Oncology Database were included into this retrospective study. Kaplan-Meier curve and multivariate Cox proportional models were used to calculate the overall survival of patients with sarcoma who underwent radical excision surgery.

    RESULTS: High preoperative LMR is significantly associated with better overall survival and prognosis in sarcoma patients, whereas high preoperative NLR is significantly associated with shorter overall survival and poorer prognosis. Multivariate analysis shows that LMR and NLR are good predictors for overall survival at 3 and 5 years after surgery, respectively. Patients with high preoperative lymphocytes count are associated with longer overall survival, but this association is not statistically significant. Our findings suggest that preoperative NLR and LMR are good predictive markers for survival of sarcoma patients.

    CONCLUSION: LMR and NLR can be used to identify patients at risk for poor clinical outcome, so that a more aggressive course of treatment can be applied to improve outcome. These are cost-effective prognostic tools as they are calculated from routine preoperative peripheral blood counts. In conclusion, preoperative NLR and LMR are good prognostic markers for predicting the clinical outcome of patients with sarcoma.

    BACKGROUND: This prospective clinical-radiological study was conducted to determine whether the dynamic mobility stress radiographs can predict the postoperative vertebral height restoration, kyphosis correction, and cement volume injected after vertebroplasty.

    METHODS: Patients included had the diagnosis of significant back pain caused by osteoporotic vertebral compression fracture secondary to trivial injury. All the patients underwent routine preoperative sitting lateral spine radiograph, supine stress lateral spine radiograph, and supine anteroposterior spine radiograph. The radiological parameters recorded were anterior vertebral height (AVH), middle vertebral height (MVH), posterior vertebral height (PVH), MVH level below, wedge endplate angle (WEPA), and regional kyphotic angle (RKA). The supine stress versus sitting difference (SSD) for all the above parameters were calculated.

    RESULTS: A total of 28 patients (4 males; 24 females) with the mean age of 75.6 ± 7.7 years were recruited into this study. The mean cement volume injected was 5.5 ± 1.8 ml. There was no difference between supine stress and postoperative radiographs for AVH ( p = 0.507), PVH ( p = 0.913) and WEPA ( p = 0.379). The MVH ( p = 0.026) and RKA ( p = 0.005) were significantly less in the supine stress radiographs compared to postoperative radiographs. There was significant correlation ( p < 0.05) between supine stress and postoperative AVH, MVH, PVH, WEPA, and RKA. The SSD for AVH, PVH, WEPA, and RKA did not have significant correlation with the cement volume ( p > 0.05). Only the SSD-MVH had significant correlation with cement volume, but the correlation was weak ( r = 0.39, p = 0.04).

    CONCLUSIONS: Dynamic mobility stress radiographs can predict the postoperative vertebral height restoration and kyphosis correction after vertebroplasty for thoracolumbar osteoporotic fracture with intravertebral clefts. However, it did not reliably predict the amount of cement volume injected as it was affected by other factors.

    PURPOSE: To determine consensus among Asia-Pacific surgeons regarding nonoperative management for adolescent idiopathic scoliosis (AIS).

    METHODS: An online REDCap questionnaire was circulated to surgeons in the Asia-Pacific region during the period of July 2019 to September 2019 to inquire about various components of nonoperative treatment for AIS. Aspects under study included access to screening, when MRIs were obtained, quality-of-life assessments used, role of scoliosis-specific exercises, bracing criteria, type of brace used, maturity parameters used, brace wear regimen, follow-up criteria, and how braces were weaned. Comparisons were made between middle-high income and low-income countries, and experience with nonoperative treatment.

    RESULTS: A total of 103 responses were collected. About half (52.4%) of the responders had scoliosis screening programs and were particularly situated in middle-high income countries. Up to 34% obtained MRIs for all cases, while most would obtain MRIs for neurological problems. The brace criteria were highly variable and was usually based on menarche status (74.7%), age (59%), and Risser staging (92.8%). Up to 52.4% of surgeons elected to brace patients with large curves before offering surgery. Only 28% of responders utilized CAD-CAM techniques for brace fabrication and most (76.8%) still utilized negative molds. There were no standardized criteria for brace weaning.

    CONCLUSION: There are highly variable practices related to nonoperative treatment for AIS and may be related to availability of resources in certain countries. Relative consensus was achieved for when MRI should be obtained and an acceptable brace compliance should be more than 16 hours a day.

    BACKGROUND: Strayer's gastrocnemius recession is a common technique in treating ankle equinus of gastrocnemius origin. Nevertheless, this technique is associated with a few flaws. We aim to introduce a novel technique of isolated gastrocnemius recession and perform a cadaveric study to evaluate its safety and at the same time compare this novel technique with the existing Strayer procedure biomechanically.

    METHODS: Eight fresh cadaveric models of gastrocnemius tightness were established by isolated traction of the gastrocnemius muscles. Gastrocnemius recession was performed on all eight models with Strayer method and the novel method randomized equally. The safety of both the techniques was evaluated by identifying any iatrogenic injury to the surrounding structures. The lengthening and improvement of the ankle dorsiflexion was measured and compared between the two techniques.

    RESULTS: There was no iatrogenic sural nerve or saphenous vein injury in all eight models. There was no significant difference between the two techniques in terms of lengthening (24.25 mm vs 21.00 mm; p = 0.838) and improvement of ankle dorsiflexion (26.5° vs 26°; p = .829).

    CONCLUSIONS: Both Strayer technique and the novel technique of gastrocnemius recession lengthened the gastrocnemius and improved the ankle dorsiflexion in this cadaver trial. Both procedures were safe with proper techniques, and there was no significant difference in efficacy between them.

    LEVEL OF EVIDENCE: Level II, randomized controlled trial.

    The advancement in science and research has led to development of medical maggots which feed exclusively on dead tissue. Medical maggots have three important functions namely debridement, disinfection, and stimulation of wound healing. The modern use of medical maggots now goes by the term "Maggot Debridement Therapy" (MDT) for use in wound management. MDT is still used infrequently due to the effectiveness of surgical debridement and antibiotics for treatment of wound infection. Lately, there was emergence of Multi-Drug Resistant Organism (MDRO) likely due to inappropriate antibiotics usage. Maggot secretions have been shown to be effective in inhibiting some MDRO, for example, Methicillin-resistant Staphylococcus aureus, thus making MDT an attractive option for wounds with MDRO. We report two patients with multiple medical comorbidities, diagnosed with serious MDRO Diabetic Hand Infections treated with three cycles of MDT followed by Negative Pressure Wound Therapy.

    PURPOSE: Giant cell tumour (GCT) of the bone is a benign but locally aggressive tumour, commonly occurs at the metaphyseal-epiphyseal junction of the distal femur, proximal tibia, and distal radius. For Campanacci grade II and III lesions of the distal radius and in cases of recurrence, we usually carry out wide resection and reconstruction. There are numerous publications on the treatment of GCT of the distal radius. Still, reports on the functional outcome using non-vascularized fibular graft arthroplasty without fusion remain limited.

    METHOD: We reviewed patients who underwent wide resection and non-vascularized fibular graft arthroplasty from 2007 to May 2014. The assessment was done with Musculoskeletal Tumour Society Score (MSTS), Toronto Extremities Scoring System (TESS) and Disability of the Arm, Shoulder and Hand (DASH) scores. We also reviewed the radiographic results.

    RESULTS: Fifteen patients were recruited, of whom 10 cases used ipsilateral fibular graft and five used contralateral non-vascularized fibular graft. The average duration of follow up was 6 years (3.25-9.92 years). The average grip strength was 48.1% compared to the non-operated hand. The average MSTS score was 78.4 %, TESS score was 84%, and DASH score was 25.2. The average time to radiological union was 12.5 weeks. 64% (29-78%) of the range of movement is preserved compared to the normal side. The complication rate was 20%.

    CONCLUSION: Fibula autograft arthroplasty is a feasible method of reconstruction after distal radius resection with good functional outcomes.
