    Mohamed Thajudeen MZ, Mahmood Merican A, Hashim MS, Nordin A
    Medicine (Baltimore), 2022 Nov 11;101(45):e31398.

    Femoral anteversion is an important parameter that can prevent complication following total hip arthroplasty (THA) caused by improper positioning of the implant. However, assessing femoral anteversion can be challenging in situation with significant defect of the femoral neck. In this study, linea aspera version was nominated as alternative parameter to femoral anteversion. So, the main objective of this study is to determine whether femoral anteversion correlates with linea aspera version. Cross-sectional study. Three-dimensional images of 100 femora were generated and their femoral anteversion and linea aspera version was measured. Correlation between the parameters was calculated. The mean linea aspera version was 7.27° ± 12.17° (mean ± standard deviation) while the mean femoral anteversion was 11.84° ± 10.06°. The linea aspera version was inversely correlated with the femoral anteversion with a correlation coefficient of -0.85. Linea aspera should be considered as an additional bony landmark to assess proper implant positioning in THA.

    Osteomyelitis refers to an infection of the bone characterized by progressive inflammatory destruction caused by infecting microorganism. Open fracture carries the risk of developing osteomyelitis from 3 to 50% with a high amputation rate. Salvage of the limb is always a challenge and needs perseverance. We report the case of a 44-year-old male with chronic osteomyelitis with successful multiple limb salvage surgeries. The curative approach to chronic osteomyelitis has the following goals including arrest of infection, pain reduction and salvage of limb and function. With regard to survival and function, the result obtained in this case is more promising compared to above knee amputation.

  5. Fulltext Scanning Electron Microscopy Study of Retrieved Implants Suggests a Ratcheting Mechanism Behind Medial Migration in Cephalomedullary Nailing of Hip Fractures

    Malays Orthop J, 2020 Mar;14(1):7-17.
    PMID: 32296476 DOI: 10.5704/MOJ.2003.002
    Introduction: Medial migration is the paradoxical migration of the femoral neck element (FNE) superomedially against gravity with respect to the intramedullary component of the cephalomedullary device, increasingly seen in the management of pertrochanteric hip fractures with the intramedullary nail. We postulate that the peculiar anti-gravity movement of the FNE in the medial migration phenomenon stems from a ratcheting mechanism at the intramedullary nail-FNE interface, which should inadvertently produce unique wear patterns on the FNE that can be seen with high-powered microscopy. By examining the wear patterns on retrieved implants from patients with medial migration, our study aims to draw clinical correlations to the ratcheting mechanism hypothesis.

    Material and Methods: Four FNEs were retrieved from revision surgeries of four patients with prior intramedullary nail fixation of their pertrochanteric hip fractures complicated by femoral head perforation. The FNEs were divided into two groups based on whether or not there was radiographic evidence of medial migration prior to the revisions. Wear patterns on the FNEs were then assessed using both scanning electron microscopy and light microscopy.

    Results: Repetitive, linearly-arranged, regularly-spaced, unique transverse scratch marks were found only in the group with medial migration, corresponding to the specific segment of the FNE that passed through the intramedullary component of the PFNA during medial migration. These scratch marks were absent in the group without medial migration.

    Conclusion: Our findings are in support of a ratcheting mechanism behind the medial migration phenomenon with repetitive toggling at the intramedullary nail-FNE interface and progressive propagation of the FNE against gravity.

  7. Fulltext Is the femoral neck geometry adequate for placement of the proximal femoral nail in the Malaysian population? A review of 100 cases
    Chiu CK, Chan CY, Singh VA
    Med J Malaysia, 2009 Mar;64(1):22-6.
    PMID: 19852315
    Issues that had been encountered during proximal femoral fracture fixation using proximal femoral nail include (i) the adequacy of the femoral neck width in the local population and (ii) the potential difficulty encountered during fixation in certain prefixed angles as determined by the implant. This was a retrospective, descriptive study evaluating the anterior-posterior pelvic radiographs of 100 consecutive patients, from January to August 2007, managed at University Malaya Medical Centre, Kuala Lumpur. The femoral neck width in the population studied was adequate for placement of femoral neck screw and anti-rotation pin or hip pin using the proximal femoral nail implant. (mean = 34.0 +/- 3.7 mm, min = 24.6 mm). There was no significant difference between the working area using an implant angled at 130 degrees or 135 degrees (P = 0.91). Both femoral neck width and neck shaft angle of the Malaysian population studied were not a factor influencing the placement of femoral neck lag screws and anti-rotation pin.

  9. Fulltext Ipsilateral femoral fracture non-union and delayed union treated by hybrid plate nail fixation and vascularized fibula bone grafting: a case report

    PMID: 25722826 MyJurnal DOI: 10.5704/MOJ.1307.012
    Non-union is a well recognized complication of femoral neck fractures. The decision whether to attempt fracture fixation or to resort to hip replacement is particularly difficult in patients in the borderline age group in whom complex attempts at gaining union may fail and later present a difficult revision. On the other hand the patient may be young enough that arthroplasty best be avoided . Besides, presence of ipsilateral femoral shaft fracture with delayed union in addition to the femoral neck non-union will pose major problems at operation. We share our experience in treating a femoral neck fracture non-union with ipsilateral femoral shaft delayed union in the shaft and in the distal femur in a fifty years old patient. The fracture was treated with an angle blade plate and supracondylar nail supplemented with a free vascularised fibular bone grafting and autologous cancellous graft. There was radiological union at fourth month. At sixth months, the patient was free of pain and able to walk without support. Thus, we would like to suggest that vascularised fibula bone grafting with supracondylar nailing is a viable option for this pattern of fracture.

    A 47-year-old gentleman, with underlying seborrhoeic dermatitis that was treated with steroid therapy, and hepatitis B, presented with pain in his right hip. He was diagnosed with stage 2 osteonecrosis of the right hip (Ficat and Arlet classification). Core decompression and bone grafting was performed but recovery was complicated by a surgical site infection. Wound debridement, removal of bone graft and clearance of the bone tunnel were carried out. The patient was allowed to bear weight after surgery. Twelve days later, he developed right hip pain and radiographs showed fractured femur neck; the patient then underwent a two-stage total hip replacement (THR).

    Salvage total hip arthroplasty (THA) may be required to manage femoral neck fracture implant failures, avascular necrosis and secondary hip arthritis. Cannulated cancellous screws can become stripped or incarcerated during the initial implantation and pose hardware removal issues. We present a novel technique for safe screw removal in a 62-year-old female patient with a painful right hip. She had undergone cancellous screw fixation for a fracture of the neck of femur ten years ago. There was avascular necrosis with screw cut out leading to secondary hip arthritis necessitating THA. Intra-operatively cannulated cancellous screw along the inferior femoral neck region was incarcerated. After posterior dislocation of the head, the neck was osteotomised, and the screw threads were exposed for possible extraction. However, the thickened femoral neck region with solid cortical bone prevented the screw disengagement in either direction. The screw along the femoral trochanter region was cut with a Harrington cutter and the remaining screw disengaged with careful removal of bony spicules and controlled anticlockwise rotations, to remove the screw in around fifteen minutes. Arthroplasty could be completed uneventfully thereafter. We could remove the screw while avoiding an iatrogenic fracture along the calcar region and excessive bone loss along the screw track. The femoral canal remained uncompromised. The anticipation of a difficult implant removal with a thorough understanding of the devices and techniques, is an invaluable asset to the operating surgeon. With a simple tool and novel technique in a difficult situation, we can save on operating time and minimise complications.

    Femoral neck stress fractures are rare in children. To the best of our knowledge, the tension type stress fracture has been reported only twice in the English language literature. We report on a five years follow-up of a 10-year-old boy with this injury which was initially missed. The fracture healed after screw fixation. We highlight the importance of considering stress fracture as a differential diagnosis in a child with chronic hip pain. A careful physical examination and the appropriate imaging will avoid missing the diagnosis.

    Fracture of the femoral neck is one of the most common types of osteoporotic fractures. Hemiarthroplasty continues to be a good option despite current calls for total hip arthroplasty in this subset of patients. The hemiarthroplasty is less expensive and easier to perform, and can be adequately carried out in smaller hospitals with basic orthopaedic facilities staffed by general orthopaedists. Functional demands of the elderly among Asians are often less compared to similar subsets of Western population on which most comparative hip studies are based. This study was undertaken to investigate the outcome for femoral neck fractures treated with conventional hemiarthroplasty. The authors hope to provide information based on local data as a reference for our doctors and patients.

    PMID: 15618601
    Ethnic differences in bone density and hip geometry are known to exist, even within the same population. A recent study in Singapore showed that there were significant racial differences in hip fracture rates, with Chinese having the highest incidence of hip fractures. The aim of this study was to compare the bone mineral density (BMD) and hip axis length in Chinese, Malay, and Indian women. A total of 1575 women aged 20-59 yr were recruited, of which 77.6% (1222) were Chinese, 7.7% (122) Malays, and 14.7% (231) Indians. There was no significant difference in peak BMD of both lumbar spine and femoral neck among the three ethnic groups. However, in the older age group (50-59 yr), both Chinese and Malay women had significantly lower femoral neck BMD compared to Indian women. There was no significant loss in BMD of the lumbar spine between the second and fifth decades in all the three races. Between the second and fifth decade, Chinese and Malay women had significant bone loss in the femoral neck of 6.6% and 8.2%, respectively, whereas Indian women did not show any significant bone loss. Chinese women had significantly longer hip axis length compared to either Malay or Indian women (9.87 +/- 0.52 cm vs 9.67 +/- 0.49 cm; p < 0.005; and 9.69 +/- 0.55 cm, p < 0.05, respectively). The initial findings suggest racial differences in bone density and hip geometry exist in the local community. Future research should include prospective, longitudinal studies to determine the age-related bone loss in these three racial groups. It is also important to investigate the differences of spine and hip fracture rates and their relationship with bone density and hip axis length.

    Minerva Endocrinol., 2019 Dec;44(4):387-396.
    PMID: 30482008 DOI: 10.23736/S0391-1977.18.02867-5
    INTRODUCTION: Recent studies showed a possible association between hyperaldosteronism and secondary hyperparathyroidism leading to reduced bone health, however results are conflicting.

    EVIDENCE ACQUISITION: We conducted a meta-analysis to evaluate the relationship between primary aldosteronism (PA) with bone biochemical markers and to assess bone mineral density in patients with primary aldosteronism.

    EVIDENCE SYNTHESIS: A total of 939 subjects were examined (37.5% with PA). Patients with PA had significantly higher serum parathyroid hormone, lower serum calcium, higher urine calcium excretion and higher serum alkaline phosphatase compared to patients without PA, with no significant difference in serum vitamin D between both groups. Bone mineral density of lumbar spine, femoral neck and total neck of femur were similar between two groups. With PA treatment, there was a significant increment in serum calcium and reduction in serum parathyroid hormone.

    CONCLUSIONS: PA is associated with hypercalciuria with subsequent secondary hyperparathyroidism. This potentially affects bone health. We recommend this to be part of complication screening among patients with PA.

    PMID: 28975432 DOI: 10.1007/s00394-017-1544-6
    PURPOSE: In Malaysia, hip fracture incidence is higher in Chinese women than other ethnic groups. This study compared the effects of a high-calcium vitamin D fortified milk with added FOS-inulin versus regular milk over 1 year on aspects of bone health in Chinese postmenopausal women in Malaysia.

    METHODS: One-hundred and twenty-one women (mean age 59 (± 4) years) were randomized into two groups: control (n = 60; regular milk, 428 mg calcium per day) or intervention (n = 61; fortified milk at 1200 mg calcium, 96 mg magnesium, 2.4 mg zinc, 15 μg vitamin D and 4 g FOS-inulin per day). At baseline, weeks 12, 24, 36 and 52, parathyroid hormone (PTH), C-Telopeptide of Type I Collagen (CTx-1), Procollagen I Intact N-Terminal propeptide (PINP) and vitamin D levels were assessed. Bone density (BMD) was measured at baseline and week 52 using a GE Lunar iDXA.

    RESULTS: Body mass index, lumbar spine and femoral neck BMD did not differ between groups at baseline. Over 52 weeks, mean plasma 25 (OH) D3 levels increased to 74.8 nmol/L (intervention group) or remained at 63.1 nmol/L (control group) (p neck BMD remained stable in the intervention group but decreased significantly in the controls, with a borderline treatment effect (p = 0.07).

    CONCLUSION: Compared with regular milk, the fortified milk suppressed bone turnover markers and tended to increase femoral neck BMD.

  19. Fulltext Relationship of Calcium Intake and Lifestyle Factors to Bone Health Status among Postmenopausal Women
    Malays J Nutr, 2000;6(1):-.
    MyJurnal
    This study aims to determine the relationship between calcium intake and lifestyle factors with bone health status among 56 postmenopausal women in the Evergreen Senior Citizens Club, Petaling Jaya. Purposive sampling technique was used for sample selection. Bone mineral density (BMD) of the femur proximal and lumbar L2-L4 was measured based on the Dual Energy X-ray Absorptionmetry (DEXA) technique at KVOTC Clinic, Subang Jaya. The interview sessions were conducted using a questionnaire followed by anthropometric measurements. The results revealed that the average age of the respondents was 64.0 years old. The average weight and height of the respondents were 53.68 kg and 1.55 meters, respectively. Overall, the average body mass index (BMI) of the respondents was quite satisfactory (22.4 kg/m²) with only 17.9% of them categorized as overweight (>25 kg/m²). The average total calcium intake was 807.31 mg and about 76.2% was contributed by food intake. About 83.9% of the respondents met the recommended calcium intake according to the Malaysian RDA. The average BMD of the lumbar, neck, wards and trochanter was 9.983 ± 0.178 g/cm², 0.745 ± 0.126 g/cm², 0.604 ± 0.150 g/cm² and 0.674 ± 0.127 g/cm², respectively. About 32.1% of the respondents were categorized as osteoporotic at the femoral wards, while 10.7% respectively was at the lumbar L2-L4 and femoral neck. Half of the respondents had osteopenia at the femoral neck (53.6%) and wards (50.0%) and at the lumbar L2-L4 (53.6%). Pearson correlation test showed significant negative correlations between age and BMD in the neck (r = -0.419, p

    Introduction: There is a lack of information on bone health status of premenopausal women in Malaysia. This study investigated the bone health status of premenopausal women and its associations with anthropometric, dietary and physical activity. Methods: Bone mineral density (BMD) was measured using dual X-ray absorptiometry (DEXA) at the lumbar spine, femoral neck, total hip and total body. Serum osteocalcin, parathyroid hormone (PTH), beta-crosslaps were also determined. Results: A total of 73 Chinese premenopausal women were recruited in the study with a mean age of 39.3 ± 5.0 years. Average BMI, body fat percentage and lean body mass were 22.2 ± 3.4 kg/m2, 33.9 ± 4.6% and 34.5 ± 4.4 kg, respectively. Mean BMD at the spine, total hip, femoral neck, and total body were 1.025 ± 0.118 g/cm2, 0.876 ± 0.109 g/cm2, 0.739 ± 0.110 g/cm2, and 1.061 ± 0.755 g/cm2, respectively. Their serum beta-crosslaps and PTH were within normal range, but serum osteocalcin (8.5 ± 4.2 ng/ ml) was low. On average, calorie intake (1506 ± 427 kcal/ day) was below the Malaysian Recommended Nutrient Intake (RNI) while their calcium intake achieved only 67% of RNI. Their mean metabolic equivalent score (MET) was 771.4 ± 926.1 min/week. Body weight and related indices (BMI, lean mass, fat mass) were significantly positively correlated with BMD at all skeletal sites. Conclusion: The study revealed that Chinese premenopausal women in the Klang Valley have low calcium intake and low level of physical activity.
