Intra-Articular Distal Radius Fracture with Lunate Fossa Rotated and Associated Lesions: Radiologic Analysis

Introduction: Intra-articular distal radial fractures in young patients occur in high energy trauma which can lead to a combination of bone and ligaments lesions. An articular step superior to 2 mm is pejorative, for that an adequate radiologic analysis is necessary accessing to the best surgical treatment. The purpose of our study was to investigate this type of fracture and expose radiologic analysis (radiograph and CT-scan) of bone and ligamentous associated lesions of this specific twisted lunate facet fracture for recognizing it and accessing to the best surgical treatment. Patients and Methods: Seven patients with severely displaced type 4 articular fractures of the distal radius whose wrists had been exposed to violent compression are reported in our series, they are required open treatment for the reduction and fixation of disrupted articular surfaces by using an antero-medial approach which allows direct access to the fragment of the lunate facet and easier visualization of the distal radio-ulnar joint. Results: All the patients were clinically examined with antero-posterior and lateral X ray, completed by a CT scan, all the fractures were type IV according to Melone classification. In all of our seven cases there was a lesion of the distal radioulnar joint (DRUJ) identified in the CT scan. The CT scan allowed us to individualize well the void of the lunate fossa and calculate his exact degree of rotation, which is very important for planning therapeutic management. Discussion: In all of our cases the CT scan was to expose all of the osseous and ligamentous injuries;in the sagittal reconstruction we were able to objectify and calculate the exact degree of the rotation of the lunate fossa fragment;in the frontal reconstruction the void of the lunate fossa is visible and in the axial reconstruction we can determine the incongruence of the distal radio-ulnar joint (DRUJ). Intra-articular involvement has long been recognized as a poor prognostic factor in fractures of the distal radius. However, despite early studies reporting poor results with non operative treatment for these injuries, most authors opposed operative intervention, due to lack of a good radiological analysis and the CT scan;knowledge that a number of studies have shown that inadequate reduction of intra-articular distal radius fractures leads to the development of arthritis.

Comparison of intra-articular injection of parecoxib vs oral administration of celecoxib for the clinical efficacy in the treatment of early knee osteoarthritis

BACKGROUND Non-steroid anti-inflammatory drugs(NSAIDs)have played a crucial role in the treatment of osteoarthritis,especially in the early stages.However,the cardiovascular risk and adverse gastrointestinal reactions of oral NSAIDs in elderly people cannot be underestimated.Intra-articular injection of NSAIDs may be a new attempt for early knee osteoarthritis treatment.Parecoxib may be a suitable drug for intra-articular injection.AIM To observe the clinical efficacy of the intra-articular injection of parecoxib for early knee osteoarthritis.METHODS Early knee osteoarthritis patients(n=110)were retrospectively analyzed.These patients were divided into three groups:Basic treatment+oral glucosamine(group A,n=37),oral celecoxib+basic treatment+oral glucosamine(group B,n=37),and intra-articular injection of parecoxib+basic treatment+oral glucosamine(group C,n=36).Intra-articular injection of parecoxib was performed once every 2 wk at a dose of 40 mg each time,for three times total.The three groups were compared in terms of visual analogue scale(VAS)scores,Hospital for Special Surgery(HSS)scores and patient satisfaction before and after treatment.The levels of inflammatory cytokines in the synovial fluid were detected in the three groups before and after treatment.RESULTS All patients were followed up for an average of 15.5±2.7 mo.The clinical efficacy was estimated by VAS and HSS scores at 12 mo after treatment.Inflammatory cytokine levels in the synovial fluid were evaluated at 3 mo after treatment.VAS and HSS scores were significantly improved in each group compared with before(P<0.001).There were significant differences among the three groups in VAS and HSS scores(P<0.001).The clinical efficacy of group C was superior to that of groups A and B(P<0.001),while group B outperformed group A in this respect(P<0.001).The patient satisfaction was the highest in group C(P<0.001).After treatment,the levels of tumor necrosis factorα(TNF-α)and interleukin(IL)-6 in the synovial fluid decreased in each group compared with before(P<0.001),while the levels of IL-10 increased(P<0.001).The three groups differed significantly in the levels of TNF-a,IL-6 and IL-10 in the synovial fluid after treatment(P<0.001).CONCLUSION For patients with early knee osteoarthritis,intra-articular injection of parecoxib could effectively improve clinical symptoms.This method may be a reliable alternative for early knee osteoarthritis.

Intra-articular delivery of tetramethylpyrazine microspheres with enhanced articular cavity retention for treating osteoarthritis

Tetramethylpyrazine(TMP) is a traditional Chinese herbal medicine with strong antiinflammatory and cartilage protection activities, and thus a promising candidate for treating osteoarthritis. However, TMP is rapidly cleared from the joint cavity after intra-articular injection and requires multiple injections to maintain efficacy. The aim of this study was to encapsulate TMP into poly(lactic-co-glycolic acid)(PLGA) microspheres to enhance the TMP retention in the joint, reducing injection frequencies and decreasing dosage. TMP microspheres were prepared by emulsion/solvent evaporation method. The intra-articular retention of the drug was assessed by detecting the drug concentration distributed in the joint tissue at different time points. The therapeutic effect of TMP microspheres was evaluated by the swelling of knee joints and histologic analysis in papain-induced OA rat model. The prepared freezedried microspheres with a particle size of about 10 μm can effectively prolong the retention time of the drug in the articular cavity to 30 d, which is 4.7 times that of the TMP solution.Intra-articular injection of TMP microspheres efficiently relieved inflammatory symptoms,improved joint lesions and decreased the depletion of proteoglycan. In conclusion, intraarticular injection of TMP loaded microspheres was a promising therapeutic method in the treatment of OA.

Intra-articular transplantation of porcine adipose-derived stem cells for the treatment of canine osteoarthritis: A pilot study

AIM: To test whether intra-articular injection of porcine adipose-derived stem cells(ADSCs) can treat canine osteoarthritis(OA).METHODS: To enroll in this study dogs must have stifle joint OA that had lasted ≥ 3 mo and been treated with OA medication without significant improvement. Three dogs fulfilled these criteria and were thus subjects for ADSCs treatment. ADSCs were isolated from abdominal adipose tissue of a 2-mo-old female Yorkshire pig. Their stem cell marker expression was examined by immunofluorescence staining. For treatment, 5 million ADSCs were injected into the diseased joint of each dog. In the next 48 h, the patient was observed for signs of inflammatory and allergic reactions. Thepatient was then discharged to the owner and, at 2, 6, and 12 wk, followed up with orthopedic assessment, owner questionnaire, X-ray imaging, and force-plate gait analysis.RESULTS: Porcine ADSCs expressed mesenchymal stem cell markers CD90 and CD105. Injection of porcine ADSCs into canine stifle joints did not cause any inflammatory or allergic reactions. Orthopedic evaluation found improvements in two dogs, particularly at the longest time point. Owners' evaluation found increased capacity and decreased pain in all three dogs' activities such as walking and running. Radiographic evaluation did not find statistically significant differences before and after treatment. Force-plate analysis found significant improvements in all three dogs after treatment.CONCLUSION: Xenotransplantation of ADSCs for the treatment of OA is feasible. Further studies are needed to validate this novel treatment modality, which can then be implemented for the routine treatment of OA in veterinary medicine.

Nanoparticle–Cartilage Interaction: Pathology-Based Intra-articular Drug Delivery for Osteoarthritis Therapy

Osteoarthritis is the most prevalent chronic and debilitating joint disease,resulting in huge medical and socioeconomic burdens.Intra-articular administration of agents is clinically used for pain management.However,the effectiveness is inapparent caused by the rapid clearance of agents.To overcome this issue,nanoparticles as delivery systems hold considerable promise for local control of the pharmacokinetics of therapeutic agents.Given the therapeutic programs are inseparable from pathological progress of osteoarthritis,an ideal delivery system should allow the release of therapeutic agents upon specific features of disorders.In this review,we firstly introduce the pathological features of osteoarthritis and the design concept for accurate localization within cartilage for sustained drug release.Then,we review the interactions of nanoparticles with cartilage microenvironment and the rational design.Furthermore,we highlight advances in the therapeutic schemes according to the pathology signals.Finally,armed with an updated understanding of the pathological mechanisms,we place an emphasis on the development of“smart”bioresponsive and multiple modality nanoparticles on the near horizon to interact with the pathological signals.We anticipate that the exploration of nanoparticles by balancing the efficacy,safety,and complexity will lay down a solid foundation tangible for clinical translation.

Continuous Intra-Articular Ropivacaine/Tramadol Combination Infusion Therapy Improves Postoperative Outcome of Total Knee Arthroplasty

Objectives: To evaluate the postoperative analgesic yield of continuous intra-articular (IA) ropivacaine/tramadol infusion as against infusion of ropivacaine alone after total knee arthroplasty. Patients and Methods: Sixty patients accompanied by arthrosis were randomly divided into three equal groups: The ropivacaine group, which obtained a continuous intraarticular (IA) infusion of ropivacaine alone;the combination group, which obtained a continuous (IA) infusion of a combination of ropivacaine and tramadol at a rate of 6 ml/h for 72 h postoperatively;and the control group, which did not receive IA medications. After release of the ischemic tourniquet and assurance of haemostasis, a vacuum drainage tube was applied. The (IA) infusion was delivered through a multipored catheter for 72 h. Postoperative pain was assessed using visual analogue pain scale (VAS), and intravenous meperidine was administered as rescue analgesia if the (VAS) pain score was greater than or equal to (4) or on patient’s request. The total rescue analgesia consumption, angle of flexion of the knee and hospital stay were recorded. Results: The ability to achieve better angle of flexion was significantly higher in the combination group compared with the other groups, with a significant difference in favour of the ropivacaine group compared with the control group. At 2 h postoperatively, the mean pain (VAS) scores were significantly lower in patients who received (IA) analgesia compared with the control group and in the ropivacaine/tramadol group versus the ropivacaine group. The number of requests and total dose of rescue analgesia consumed were significantly lower with (IA) analgesia, with a significant difference in favour of the combination group. There was significant correlation between pain (VAS) scores and angle of flexion of the knee joint. Conclusion: Continuous (IA) ropivacaine/tramadol infusion safely reduced postoperative pain and spared administration of rescue analgesics with a significantly improved range of joint movement.

Primary Combined Intra-articular and Extra-articular Synovial Osteochondromatosis of Shoulder: a Case Report

PRIMARY synovial chondromatosis is a rarecondition in which foci of cartilage develop in thesynovial membrane of joints, bursae and tendonsheaths. It typically involves a single large jointin a young adult male.1 The ectopic foci of cartilage canresult in painful joint effusion, and the generation of loosebodies can cause mechanical symptoms.2,3 The etiology ofprimary synovial chondromatosis remains unknown, butmetaplastic theory is the most popular hypothesis. Thecommonly involved joints are knee, elbow, and hip.^4 Theshoulder is a rare site of synovial chondromatosis2,3,5 andthe extra-articular involvement even rarer, with only fewcases presented in literature. This report presents a rarecase of primary combined intra-articular andextra-articular synovial chondromatosis of shoulder jointtreated with arthroscopy.

Target Transfusion Intra-Articular Therapy for Osteoarthritic Joints

The comparison of biochemical composition and biophysical properties of synovial fluid and blood serum leads to a conclusion about the pathogenetic expediency of using serum as a corrector of synovial medium of osteoarthritic joints. Serum modification was realized by preliminary prescription of a single-dose drug to the patient. Then, the patient’s blood was sampled in the period of its maximal saturation with the drug. Autoserum from such blood samples was injected thrice into the knee joints affected by osteoarthritis of the 2nd or 3rd stages. The value of treatment results after 4 - 6 months of described therapeutics shows a significantly better therapeutic effect in the experimental of patient’s group as compared with the control group. The effect is connected with pain diminishing, normalization of the tissue joint nutrition, suppression of the local inflammation, and improvement of cartilage lubrication.

Arthroscopic Assessment of Intra-Articular Injury in Patients with Acute Unstable Malleolar Fracture

Introduction: Purpose to study prevalence of the intraarticular chondral lesion in the malleolar fracture by using ankle arthroscopy to fully understand the severity and complexity of the injury. Methods: Cross sectional study of 32 patients diagnosed with ankle fracture and undergone open reduction and internal fixation with arthroscopic assessment performed stimultaneously. The mechanism of injury, patterns of injury and intraarticular chondral injury were documented. Results: Mean age was 38 years (SD = 14.1, range 18 - 68 years). Eighteen were female and 14 were male. Fifteen involved syndesmostic distruption, 22 had Danis-Weber B injury and 16 had supination external rotation (SER). Ten (31.2%) had positive intraoperative cartilage injury. Significant correlation between the Lauge-Hansen classifications with positive findings with 6 had SER, 2 had pronation adduction and 2 had pronation external rotation. Conclusion: The prevalence of chondral injury in ankle fracture was quite high and may leads to poor outcome. Arthroscopy procedure allow surgeon to assess intraarticular surface and reduction of the ankle fracture which prompt further intervention that may improve the clinical outcomes and prognosis of the patients.
