    摘要：We present a unique case of tibial post fracture of a posterior-stabilised total knee arthroplasty (PS-TKA) using highly crosslinked polyethylene (HXLPE) in the unafflicted limb of a patient who had poliomyelitis. The tibial post is an upright structure perpendicular to the PE insert articular surface which articulates with the cam of the femoral component to prevent excessive posterior translation of the tibia. We explore the choice of PS polyethylene (PE) inserts in patients with neuromuscular disorders (NMD). A 74-year old gentleman presented with recurrent knee pain seven years after the index PS-TKA with HXLPE. The TKA was performed on the unafflicted left limb (contralateral to the weak side affected by poliomyelitis). The posterior drawer test was positive. During the single-stage revision surgery, the HXLPE tibial post was noted to be broken. The liner was replaced with a thicker non-HXLPE. The patient achieved an excellent outcome at one-year post-surgery. This is the first report of HXLPE tibial post fracture in the unaffected knee of a patient with NMD affecting the lower limb. The HXLPE’s reduced resistance to fatigue crack propagation might not be suitable in PS-TKA where there might be focal stress points on the tibial post, which was amplified in this case as it was the limb that the patient most depended on. When managing end-stage osteoarthritis with TKA in the unafflicted knee of a patient with NMD causing lower limb weakness, the selection of polyethylene material in PS-TKA may need more consideration than previously thought.

    【2hr】Aneurysmal Bone Cyst after Femoral Derotational Osteotomy: A Case Report

    机译 股骨转位截骨术后的动脉瘤性骨囊肿：一例报告
    摘要：Aneurysmal bone cysts rather than local aggressive lesions of the bone which may arise in any part of the axial or appendicular skeleton. Although several theories are available in the literature, the pathogenesis is still conflicting. We report an exceptional case of an aneurysmal bone cyst in the distal femur of a female cerebral palsy patient who underwent bilateral distal femoral derotational osteotomy and plate-screw fixation operations when she was 11 years old. Twenty-four months after the operation, radiographs showed a cystic lesion in the distal portion of the right femur around the osteotomy site. The diagnosis of Aneurysmal Bone Cyst (ABC) was made and the lesion was treated by curettage with cement application. After 36 months of follow-up, there was no recurrence. This is the first case reported in literature which raises the possibility that an osteotomy could be a cause in the development of an aneurysmal bone cyst.

    机译 严重刚性神经肌肉性脊柱侧弯的晕轮引力矫正术（附三例报告）
    摘要：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.

    摘要：Pseudogout and gout are common types of inflammatory joint disease in the elderly. However, the existence of both in a single joint in a patient is relatively rare. This case report describes an interesting case of a 42-year old man who presented with simultaneous gout and pseudogout in the knee joint, diagnosed via polarised light microscopy. There was no radiographic evidence of pseudogout. This case report serves to illustrate the need to actively exclude concomitant pseudogout, especially in patients suffering from recurrent attacks of gout.

    摘要：Femoral condyle fracture in coronal plane, also known as Hoffa fracture, is a rare fracture. Non-union of Hoffa fracture is even rarer. We present a case of fibrous nonunion of a Hoffa fracture in which the fractured fragment, though not freely movable, led to painful walking. Since the fragment was un-displaced and non-movable we fixed the fractured fragment in situ. Patient regained full range of motion of the knee and was asymptomatic on follow-up.

    【2hr】Relative Telomere Length in Blood Leukocytes of Patients with Anterior Cruciate Ligament Injury: A Pilot Study

    包量

    机译 前交叉韧带损伤患者血白细胞相对端粒长度的初步研究
    摘要：Introduction: Anterior cruciate ligament (ACL) tear is the most common knee ligament injury, especially in athletes. The objective of this study was to investigate relative telomere length (RTL) in blood leukocytes of patients with ACL injury compared with that of controls.Materials and Methods: A total of 187 subjects were invited to participate in this study. Ninety-two patients with clinically diagnosed ACL rupture were enrolled. Ninety-five age and gender-matched healthy controls were also recruited. Blood leukocyte RTL were analysed using quantitative real-time polymerase chain reaction.Results: Patients with ACL rupture had significantly longer relative telomere length than healthy controls (P=0.002). The patients with ACL rupture were classified into two groups according to the sport history of patients which are contact sports and non-contact sports. RTL in patients with non-contact sports was significantly greater than those with contact sports (P=0.006). Moreover, RTL was inversely correlated with body mass index of patients with ACL injury (r=-0.34, P=0.001). Logistic regression analysis indicated that long RTL was associated with a higher risk of ACL rupture.Conclusion: The present study showed that subjects with ACL rupture had significantly greater telomere length compared with their age and gender-matched controls. This finding may result from the increases in physical activity and overexpression of telomerase which acts as a protective mechanism against ACL injury. RTL in blood leukocytes is associated with a risk of ACL rupture.

    摘要：Introduction: Post-implantation rod deformation is anticipated in scoliosis surgery but the difference in rod deformation between titanium and cobalt chrome rod has not been elucidated. This study aims to compare the difference in rod deformation between two groups.Materials and Methods: Twenty-one adolescent idiopathic scoliosis (AIS) patients were recruited from a single center. The over-contoured concave rods were traced prior to insertion. Post-operative sagittal rod shape was determined from lateral radiographs. Rod deformation was determined using maximal rod deflection and angle of the tangents to rod end points. The differences between pre- and post-operative rod contour were analysed statistically. Rod deformation and thoracic kyphosis between two types of implants were analysed.Results: Both rods exhibited significant change of rod angle and deflection post-operatively. Curvature of the titanium rod and cobalt chrome rod decreased from 60.5° to 37°, and 51° to 28° respectively. Deflection of titanium rod and cobalt chrome rod reduced from 28mm to 23.5mm and 30mm to 17mm respectively. There was no significant difference between titanium and cobalt chrome groups with regard to rod angle (p=0.173) and deflection (p=0.654). Thoracic kyphosis was increased from 20° to 26° in titanium group but a reduction from 25° to 23° was noticed in cobalt chrome group, but these findings were not statistically significant.Conclusion: There was no statistical difference in rod deformation between the two groups. Thus, the use of titanium rod in correction of sagittal profile is not inferior in outcome compared with cobalt chrome but with lower cost.

    【2hr】Intra- and Inter-observer Variability in Different Methods of Measuring Carpal Collapse

    包量

    机译 观察者之间和观察者之间的差异，以不同的方式测量腕骨塌陷
    摘要：Introduction: Carpal collapse of wrist occurs in disorders like rheumatoid arthritis and Kienbock's disease. Three techniques have been described to measure carpal collapse. First, the carpal height ratio (CHR), measured by dividing carpal height by 3rd metacarpal length. Second, the revised carpal height ratio (RCH ratio), measured by dividing carpal height by length of capitate. Third, capitate radius distance (CR index), measured by shortest distance between distal edge of radius and the proximal edge of capitate. The index publications describe good reliability of all these but which method out of the three is best in terms of intra- and inter-observer variability is not known. The purpose of this study was to find out which method had the least inter- and intra-observer variability for determining carpal collapse.Materials and Methods: Fifty normal wrist postero-anterior radiographs were studied by three assessors who measured CHR, RCH ratio and CR index separately. The measurements were repeated after one month by all the three observers. The results were then statistically analysed.Results: The p-value was <0.001 in all the three assessors in CR index meaning that the intra-observer variability was least in CR index. For the inter-observer variability intra class coefficient of 0.9 indicated that the CR index has the least variability.Conclusion: CR index is the most reproducible method to measure carpal collapse. The method which provides accurate measurement of carpal collapse will allow better staging of carpal disorders.

    【2hr】Outcome of Islanded Gastrocnemius Musculocutaneous Flap in Orthopaedic Practice

    机译 孤岛腓肠肌皮瓣的手术结果
    摘要：Introduction: Large wounds in the leg require combination of local flaps or free flap for wound coverage. Gastrocnemius musculocutaneous flap (GMCF) allows a large wound to be covered by a single local flap. However, the conventional GMCF is often associated with donor site morbidity where the exposed soleus raphe causes poor uptake of the skin graft. Islanding the skin on the muscles allows the donor site to be closed primarily, thus avoiding the donor site morbidity.Materials and Methods: Medical records of twelve patients who underwent islanded GMCF surgery from 2004 till 2018 were reviewed retrospectively.Results: The mean age was 31 years old. Eight cases were with open fracture of the tibia, two degloving injury exposing the patella, one open fracture of patella and necrotising soft tissue infection. The wound size ranged from 12cm2 to 120cm2. All flaps survived. Three patients required skin grafting at the donor site while in the rest the donor sites were able to be closed primarily. Four patients developed deep infection, one healed after vacuum dressing, one after bone transport and one after split thickness skin graft. One patient ended up with below knee amputation after developing chronic osteomyelitis of the tibia.Conclusion: Islanded gastrocnemius musculocutaneous flap is an effective simple alternative for coverage of large soft tissue defects from the knee to half of the leg distally with minimal donor site morbidity. Aggressive debridement of unhealthy tissue is necessary to prevent infection following wound coverage with this flap.

    摘要：Introduction: Olecranon osteotomy is well described approach for complex intra-articular distal humeral fractures. In this study, we investigated the usefulness and complications of olecranon osteotomy approach for such fractures. We hypothesise that outcome is comparable in young adults and middle age group and also functional outcome is independent of fracture subtype following surgical fixation.Materials and Methods: Between December 2012 and September 2015, twenty-four adult patients (male: 15, female: 9) having mean age of 41.4 years with closed intra-articular fracture (AO-13C) were surgically managed using olecranon osteotomy approach and were followed-up for a mean of 28.5 months (range: 22-35 months). Functional outcome was measured using Mayo Elbow Performance Score (MEPS) and complications were observed. Statistical analysis was done using Student t-test and Kruskal Wallis test.Results: All fractures united by the end of three months. Mean elbow flexion achieved was 123°, mean extension lag was 9° and mean active arc of motion was 114°. Mean MEPS was 87 (excellent: 8, good: 14, fair: 1 and poor: 1). Post-operative transient ulnar nerve palsy was noted in two cases, heterotopic ossification (HO) was in one case, infection in two cases, implant prominence in five and elbow stiffness in three cases. Motion arc was higher in young adults and MEPS was comparable in both age group. Functional outcome was also dependent on fracture subtype. Conclusion: The olecranon osteotomy approach for distal humerus fractures had good functional outcome with fewer complications. Joint congruity and fixation could easily be assessed intraoperatively.

    机译 Ilizarov外固定架治疗胫骨感染性骨不连：我们的经验
    摘要：Introduction: Tibia is the most common long bone fractured due its vulnerable subcutaneous location and most often associated with acquired complications of delayed union or non-union due to infection. Amongst the various treatment options to treat them, the Ilizarov external fixator application is considered superior due to its multiple advantages. The objective of this study was to analyse the role of Ilizarov fixation in infected tibial non-union, as well as to assess bony union and associated functional outcomes.Materials and Methods: A retrospective review was conducted for the duration between 1st January 2005 to 31st December 2016. Total of fifty-one patients with tibial non-union associated with infection who treated with the Ilizarov fixator were included in the study. Patient records were reviewed for union of bone, bone and functional outcomes and complications.Results: The most common organism for infection was identified to be Staphylococcus Aureus. At the time of final follow-up all patients had achieved union except two, one of whom had to undergo amputation due to non-union and sepsis. Majority of the patients had an excellent score as per ASAMI grading system for bone and function results. The most common complication noted was pin track infections.Conclusion: In our experience, Ilizarov external fixator is better suited for infected non-union of tibia because it can provide a stable mechanical environment, bone transport, correct deformities, and enable weight bearing and hence we recommend its use for the same.

    【2hr】Extracellular Vesicles in the Synovial Joint: Is there a Role in the Pathophysiology of Osteoarthritis?

    机译 滑膜关节中的细胞外囊泡：在骨关节炎的病理生理学中有作用吗？
    摘要：The role of extracellular vesicles (EV) in osteoarthritis has become the focus of much research. These vesicles were isolated from several cell types found in synovial joint including chondrocytes and synovium. As articular cartilage is an avascular tissue surrounded by synovial fluid, it is believed that EV might play a crucial role in the homeostasis of cartilage and also could hold key information in the pathogenesis of osteoarthritis. This is thought to be due to activation of pro-inflammatory factors leading to a catabolic state and degradation of cartilage. In addition, due to the nature of articular cartilage lacking neuronal innervation, knowledge of EV can contribute to identification of novel biomarkers in this debilitating condition. This can be either directly isolated from aspirate of synovial fluid or from peripheral blood. Finally, EVs are known to shuttle important signalling molecules which can be utilised as unique modality in transferring therapeutic compounds in a cell free manner.

    摘要：We report on a 12 years old female patient who had been diagnosed with patellofemoral instability – recurrent dislocation and anterior knee pain. Radiologic evaluation further revealed osteochondritis dissecans (OCD) of the lateral femoral trochlea. She underwent surgical procedure with isolated medial patellofemoral ligament reconstruction, no surgical procedure was done to the OCD lesion. Postoperatively, there was clinical improvement of patellofemoral instability, with radiological evidence of healing of the OCD lesion. Isolated realignment procedures such as medial patellofemoral ligament reconstruction may be associated with spontaneous healing of osteochondritis dissecans of the lateral femoral trochlea.

    【2hr】Integration and Vascular Ingrowth of a Collagen Meniscal Implant: A Case Report

    包量

    机译 半月板胶原蛋白植入物的整合和血管向内生长：一例报告
    摘要：Meniscectomy is the most common surgery in orthopaedics. The absence of meniscal tissue might be related to irreversible damage to the articular cartilage. Meniscal replacement is a tissue-engineering technique for post-meniscectomy syndrome. Its success depends on the implant integration which was vastly proven in animal model studies. Histological evidence is hard to obtain in humans due to ethical issues. We report a clinical case in which a collagen scaffold meniscal implant was harvested six months after implantation due to mechanical failure. Histological analysis was performed revealing vascularisation not only of the peripheral attachment of the implant but also on the anterior horn. These morphologic findings demonstrate that this implant allows the colonisation by precursor cells and vessels, leading to the formation of a fully functional tissue. This present report is one of the few independent reports of scaffold biological integration in the literature.

    【2hr】Remodelling of Humeral Fracture in a Child with Osteopetrosis Tarda following Conservative Management - A 7-year Follow-up: A Case Report

    机译 保守治疗后骨质疏松症小儿肱骨骨折重塑-一项7年的随访：一例病例报告
    摘要：Osteopetrosis (OP) is a rare hereditary sclerosing bone dysplasia characterised by generalised hard and brittle bone secondary to defective osteoclastic function. Osteopetrotic bone is brittle, thus these subjects are prone to frequent fractures, particularly of the long bones. Due to defective osteoclastic function, remodeling is also defective in OP. This report is a case of humeral fracture in a 9 years old girl who was followed seven years. The fracture had remodeled totally similar to healthy bone at the final follow-up. Conservative treatment should be kept in mind in the management of fractures in children with OP, and fractures within acceptable angulations and/or translations should be treated conservatively without hesitation.

    摘要：Treatment of chronic Rockwood’s type V Acromioclavicular (AC) joint dislocation remains controversial. We describe a surgical technique to reduce and maintain AC joint using a combination of gracilis autograft with GraftMax™ button (Conmed Inc, Utica, NY). Graft was prepared using running whip stitch technique with No. 5 Hi-Fi high strength suture (ConMed Linvatec, Largo, FL). Our technique reduces intraoperative clavicular and coracoid tunnel fracture and restores anatomical coracoclavicular ligament. At sixth week and third month postoperatively, the patient demonstrated good clinical and radiographic outcome.

    摘要：A 58-year old female patient presented to us with a three months’ old fracture of the neck of femur. She underwent bipolar hemiarthroplasty. In the immediate postoperative period, she developed deep vein thrombosis for which she was started on anticoagulant therapy. Patient had persistent discharge from the wound since then and underwent regular dressings. On the eighth post-op day, she developed sciatic nerve palsy secondary to wound haematoma. The haematoma was decompressed immediately and she had a dramatic improvement in pain but her neurological deficit persisted. The wound healed completely without any complications. At three months follow up, she had recovered completely with grade 5/5 power in ankle and foot and full sensory recovery in the sciatic nerve distribution. She was ambulating comfortably with a walker. At final follow up around 20 months post-operation, she was pain-free and walking without any support. The wound had healed completely.

    摘要：Congenital humeroradial synostosis can occur as an isolated clinical entity or as part of a syndrome. Bilateral elbow fixed flexion deformity is very incapacitating and challenging to treat. Here we present the case of a boy with fixed flexion deformity of both elbows due bilateral humeroradial synostosis. Other characteristic features of multiple synostoses syndrome were also present in this child, his elder brother and mother. We elected to improve the position of the right elbow by adapting the modified French osteotomy described by Bellemore et al.
