Non-traumatic Ceramic Head Fracture in Total Hip Arthroplasty with Ceramic-on-Ceramic Articulation at Postoperative 16th Years.

Ceramic articulation has gained popularity in total hip arthroplasty (THA); however, one of the most important concerns about the use of ceramic materials is the potential for breakage. Importantly, almost all ceramic fractures occur within the first six years after surgery. Here, we present a case report of a 52-year-old female patient who experienced an atraumatic ceramic head fracture at the 16th year after surgery. Key parameters that may be associated with ceramic head fracture are considered to be the use of a 28-mm head and high body mass index (BMI); the patient described here had a BMI of 34.3 kg/m2. Surgical treatment of the case included removal of the broken ceramic head and replacement with an alumina matrix composite ceramic head. At the 12th month follow-up visit, the patient was mobilized independently and could perform her daily activities. Ceramic head fracture after THA may occur even in late periods after surgery. For the treatment of fractures of ceramic material, the fractured component must be removed together with extensive soft tissue excision to ensure that no residual fragments are left behind.

The effects of intra-articular levobupivacain versus levobupivacain plus magnesium sulfate on postoperative analgesia in patients undergoing arthroscopic meniscectomy: A prospective randomized controlled study.

OBJECTIVE: The aim of this study was to compared the effectiveness of intraarticular levobupivacain with levobupivacain and magnesium sulfate. METHODS: In this prospective randomized double blinded study, 96 patients (67 male, 29 female; age range: 18-65 years) with ASA (American Society of Anesthesiologist) score I and II, who had undergone arthroscopic meniscectomy operation, were divided to 3 groups that had postoperative analgesia with intra-articular saline injection (control group), levobupivacain injection (L group) or levobupivacain and magnesium sulfate injection (LM group). Patients were compared with postoperative VAS (Visual Analog Score) score during rest and activity, opioid analgesic need, non-opioid analgesic need and other medication needs. RESULTS: Postoperative VAS scores during rest and activation at early postoperative period were significantly lower at LM group when compared with L group and lower than control group at all time periods. Opioid analgesic need, non-opioid analgesic need and other medication needs for non-pain symptoms were lower at LM group when compared with L and control groups at all time periods. CONCLUSION: Intraarticular magnesium sulfate plus Levobupivacain injection is a safe and effective method for post operative pain management after arthroscopic meniscectomy.

Pedobarographic Analysis in Total Knee Arthroplasty.

Pedobarographic gait analysis is a useful tool for the determination of loading distributions and alterations on the lower extremity and their reflection on the foot sole after many orthopaedic surgical applications. To date, there have been no studies evaluating the relationship between component alignment and changes of pedobarographic gait analysis in total knee arthroplasty (TKA). We aimed to investigate the effects of TKA and prosthetic alignment on the distribution of pedobarographic parameters. Quantitative gait patterns of 47 patients were prospectively evaluated by using pedobarography 1 week before surgery and at the seventh month, on average, postoperatively. Component positions were assessed, and all applications were divided into three groups according to tibial component position as varus, neutral, and valgus. Pedobarographic results were compared between pre- and postoperative values for all applications and compared among the groups. Mean postoperative tibiofemoral angle was 5.4 degrees in valgus, and preoperative knee scores were markedly improved postoperatively. The range of tibial component alignment changed between 1 and 4 degrees in the varus and valgus groups. Plantar loading parameters (force and pressure) were significantly decreased in all operated knees, especially in forefoot and midfoot. In varus tibial components, plantar loading values decreased in midfoot and hindfoot. However, in the neutral and valgus groups, similar alterations of plantar loadings were obtained, which included decreasing in forefoot and midfoot with significant increase in hindfoot. Plantar loading distribution changed statistically significantly after TKA despite good clinical and radiographic results. Tibial component alignment was also responsible for plantar loading distribution. Tibial components in varus position create different foot loading characteristics compared with neutral and valgus aligned components. Pedobarographic evaluation in TKA allows clinicians to obtain a proper understanding of abnormal gait caused by component malposition.

Comparison of switch-therapy modalities (enoxaparin to rivaroxaban/dabigatran) and enoxaparin monotherapy after hip and knee replacement.

OBJECTIVE: Prevention of deep venous thrombosis (DVT) and associated pulmonary embolism following major orthopedic surgeries is challenging, and there is an increased interest in developing new treatment strategies. We compared 2 switch-therapy modalities-enoxaparin to rivaroxaban and enoxaparin to dabigatran-and enoxaparin monotherapy for preventing DVT after total knee arthroplasty (TKA) and total hip arthroplasty (THA). METHODS: This was a prospective, non-blinded, randomized controlled study. We selected 180 eligible patients out of 247 patients undergoing TKA or THA. During the preoperative checkup, patients were randomized to receive either enoxaparin (enoxaparin group) or switch-therapy regimens, comprising enoxaparin during hospitalization and rivaroxaban (rivaroxaban group) or dabigatran (dabigatran group) during the outpatient period. All patients were evaluated for DVT using Doppler ultrasonography (USG) 6 weeks postoperatively. The primary efficacy outcome was the prevention of symptomatic or Doppler ultrasonography (USG)-proven DVT, whereas the primary safety outcome was the incidence of bleeding during the DVT-prophylaxis period. RESULTS: Doppler USG at 6 weeks after surgery revealed no signs of DVT in any patient. During the hospitalization period, only 2 major bleeding events were reported (1 [1.6%] in the enoxaparin group and 1 [1.6%] in the dabigatran group). No major bleeding events were reported during the outpatient follow-up period in any group. Differences among the 3 groups regarding bleeding events were not statistically significant (p>0.05). CONCLUSION: When using switch-therapy modalities, clinicians can take advantage of the safety of enoxaparin during the hospitalization period and ease of use of new oral anticoagulant drugs during the outpatient period.

Etiology of coxarthrosis in patients with total hip replacement.

OBJECTIVE: We aimed to find out the distribution of etiological factors in patients who had total hip replacement for coxarthrosis. METHODS: The medical records of the 965 hips of 886 patients operated with total hip replacement between 2001 and 2012 in two separate arthroplasty clinics were analyzed by two separate senior surgeons. Each patient's pre- and postoperative X-rays and demographic data such as gender, age, side and probable etiologic factors were noted. RESULTS: Six hundred and eighty-four patients were women and 202 were men. The mean age were 62.7±14.3 (range: 16 to 91) in women, 58.8±17.1 (range: 25 to 91) in men. 52.1% of the surgeries were performed on the right side, 39% on the left, and 8.9% bilaterally. In women 36.2% of the cases were primary coxarthrosis, while the etiology was developmental dysplasia of the hip (DDH) in 43.5% of the cases, avascular necrosis in 10%, romatoid diseases in 7%, slipped capital femoral epiphysis in 5%, posttraumatic coxarthrosis in 3.9%, pathologic coxarthrosis in 1.9%, and Perthes sequel in 1.7%. In men, 24.4% of the cases were primary coxarthrosis, while the etiology was avascular necrosis in 21% of the cases, DDH in 17.6%, posttraumatic coxarthrosis in 16.8%, romatoid diseases in 10.9%, Perthes sequel in 4.2%, slipped capital femoral epiphysis in 2.5%, and pathologic coxarthrosis in 2.5%. The most common etiologic factor was DDH with a rate of 37.1%. CONCLUSION: Despite the heterogeneity of our study population, our results may reflect the distribution of coxarthrosis etiologies in Turkey. Developmental dysplasia of the hip appears to be the most frequent cause of coxarthrosis among the patients undergoing total hip replacement.

An atypically located large subchondral cyst in an osteoarthritic hip joint: a case report.

INTRODUCTION: Osteoarthritic subchondral cysts within or around the hip joint can sometimes be difficult to distinguish from primary osseous and soft tissue tumors due to their radiological appearance and uncommon location. CASE PRESENTATION: We report the case of a 74-year-old Turkish man with a subchondral cyst arising from the hip joint, eroding the acetabulum and located on the medial side of the iliac bone, which imitated a soft tissue tumor. This cystic lesion was resected and the results of histopathological analysis of tissue samples were found to be consistent with an osteoarthritic cyst. CONCLUSIONS: The present case illustrates how an osteoarthritic subchondral cyst can grow into the soft tissue planes in the presence of destruction of the articular cartilage and subchondral bone continuity, and present as an apparent soft tissue tumor.

Deep venous thrombosis and pulmonary embolism as rare complications after hallux valgus surgery: case report and literature review.

The incidence and life-threatening complications of thromboembolic disease after major orthopedic surgical procedures have been extensively defined in the medical literature. However, there are few studies concerning the incidence of thromboembolic disease after foot and ankle surgery. We describe a 57-year-old female patient who underwent surgery for bilateral hallux valgus deformities and was diagnosed as having deep venous thrombosis and pulmonary embolism after the surgery despite early mobilization and mechanical prohylaxis. Her preoperative physical examination revealed varicose veins in both cruris. She was treated for pulmonary embolism with low-molecular-weight heparin and an oral anticoagulant in the postoperative period. Although venous thromboembolism is more commonly described after proximal lower-extremity procedures, it can occur after foot and ankle surgery, particularly if the patient has certain risk factors. Therefore, in addition to mechanical prophylaxis, pharmacologic prophylaxis should be kept in mind in such patients.

[Long-term use of fondaparinux in major orthopedic surgery]. / Fondaparinuksun majör ortopedik cerrahide uzun süreli kullanimi.

OBJECTIVES: This study aims to investigate whether the usage of fondaparinux sodium may result in major hemorrhages following major orthopedic surgery. PATIENTS AND METHODS: Forty-three patients (30 females and 13 males; mean age 66 years; range 34 to 94 years) at the age of >18 years who were scheduled for major orthopedic surgery were included. Total hip arthroplasty, total knee arthroplasty and proximal femur fracture surgeries were defined as the major orthopedic surgeries. Prophylaxis was administered with 2.5 mg fondaparinux sodium once daily subcutaneously. Prophylaxis was initiated at 6-8 hours after the closure of incision. During the prophylaxis period (31±3 days), the patients were monitored for symptomatic deep venous thrombosis. Serum creatinine, platelet and hemoglobin levels were measured at the baseline and in the first week and at one month postoperatively. Wound healing time, healing complications, and major/minor hemorrhages seen during the prophylaxis period were recorded. RESULTS: During the follow-up, none of the patients had symptomatic deep vein thrombosis or symptomatic pulmonary embolism. Two patients (4.6%) had delayed wound healing, while four (9.3%) had minor ecchymosis. No major hemorrhages were observed in any patients. CONCLUSION: With the long-term use of fondaparinux, we did not observe any major hemorrhagic complications. However, further large-scale studies including control groups are required to establish the effects of long-term use of fondaparinux.

Risk factors for acute kidney injury after hip fracture surgery in the elderly individuals.

OBJECTIVE: We aimed to evaluate possible risk factors associated with acute kidney injury (AKI) after hip fracture surgery in the elderly individuals. DESIGN: Level II diagnostic study, evidence obtained from prospective cohort study from 1 center with level 2, and 3 patients. PATIENTS: A total of 165 patients (>65 years) with femoral neck fracture were enrolled in this prospective study between 2007 and 2010. Two patients were dropped for inadequate laboratory follow-up data. Patients with kidney failure or renal replacement therapy (RRT) history or AKI at admission were excluded. INTERVENTION: Nephrology consultation was obtained from all patients at admission. All patients had undergone bipolar cemented hip arthroplasty that was performed by the same surgical team in all patients within 24 hours of fracture and admission under the same protocol. MAIN OUTCOME MEASUREMENTS: Serum creatinine (SCr), urine output, and complete blood counts were evaluated at baseline and daily basis thereafter. The AKI was defined based on Acute Kidney Injury Network classification. Hospital charges were converted from Turkish Liras to US dollars and rounded. RESULTS: Among 163 patients, AKI occurred in 25 (15.3%) patients, all within the first 48 postoperative hours. Three (1.8%) patients required RRT. Baseline SCr levels were restored within 4.84 ± 1.34 days on average (3-8 days). No patient required RRT after discharge. The mean hospital stay was 3 days (2-6 days) longer and the hospital charge was 2500 US$ higher for the patients with AKI. After multivariable adjustment, only lower estimated glomerular filtration rate levels (odds ratio 0.945, 95%confidence interval 0.92-0.96) emerged as an independent predictor for AKI. CONCLUSION: The AKI represents a frequent complication after hip fracture surgery associated with longer hospital stay and higher treatment costs with increased morbidity. Our results show baseline renal function is an independent predictor of AKI.

Analyzing acetabular deficiency by computed tomography in osteoarthritis after Crowe type 2 developmental dysplasia of the hip.

OBJECTIVES: Images of acetabular deficiency in Crowe type 2 developmental dislocated hips were evaluated by computed tomography (CT) and acetabular component was placed surgically. PATIENTS AND METHODS: Twenty-nine hips of 18 patients (2 males, 16 females; mean age 46 years; range 37 to 56 years) have been reviewed through CT imaging. The roof edge angle, the acetabular index of depth to width and bone mass of the anterior and posterior acetabular rim have been measured over the cross sections obtained from the CT. RESULTS: Acetabular structure was normal in four hips, and there was no posterior rim deficiency in any hips. However, there was anterior rim deficiency in 21 hips, and there was both posterior and anterior deficiency in four hips. The acetabular anteversion was the most common finding. CONCLUSION: In this study, increased acetabular anteversion and anterior rim deficiency were frequently observed in patients with Crowe type 2 hip dislocation. An orthopaedist should consider anteversion and this deficiency when fitting acetabular component.

Surgical treatment for calcaneal intraosseous lipomas.

Intraosseous lipoma is among rare benign tumors of the bone. The aim of the present study was to evaluate the long-term surgical results of calcaneal lipomas, representing a relatively rare localization for this type of tumors. The present study included 21 calcaneal lipoma cases (22 feet) referred to our podiatry clinic between 1991 and 2001 with complaints of foot and heel pain resistant to conservative treatment for the last 3-6 months. In all cases, the diagnosis of calcaneal intraosseous lipoma was first confirmed radiologically, then histologically. The mean age was 39 years (range 16-62), 15 were females (71%) and 6 were males (29%). One patient had bilateral disease, whereas 11 and 9 patients had right and left calcaneal involvement, respectively. None of the patients have a palpable mass in their foot. For pre-operative differential diagnosis, 3 patients had computerized tomography examination (CT scan) and 8 patients underwent magnetic resonance imaging (MRI). All lesions were totally curetted out with angled curettes. The defect was filled with cancellous autografts taken from the ipsilateral iliac crest. In only four patients, the amount of autograft was not sufficient, so a combination of cancellous allograft and autograft was used. No drain was used. An elastic bandage was wrapped around the foot and ankle, and cold packs were applied to the surgical site. The mean duration of follow up was 94 (45-143) months. Pain improved in 17 feet at 4 months, in an additional 4 feet at 8 months and in the remaining one foot at 12 months. The mean time to the graft consolidation was 5 months (range 3-7 months). There were no recurrences or pathological fractures during the follow up. No wound infection or necrosis was seen at the surgical sites. There were no neurovascular complications. Five cases experienced pain in the iliac bone for 1 month, due to grafting procedures. Although calcaneal intraosseous lipoma accounts for a small portion of cases in the huge differential diagnosis chart for foot pain, it should be kept in mind as a possible diagnosis in unresolved cases. Most of the patients would benefit from non-surgical treatments. But if this is not the case, surgical treatment is indicated. In conclusion, curettage and autogenous bone grafting is an easy and effective method for the surgical treatment of calcaneal intraosseous lipomas.

Arthroscopic excision of an ununited ossicle due to Osgood-Schlatter disease.

Surgical excision of the ossicles has been suggested for unresolved sequelae of Osgood-Schlatter disease in adults resistant to conservative measures. A 24-year-old, male semiprofessional soccer player had anterior knee pain during sports activity and climbing stairs that had been treated conservatively for 2 years. On physical examination, there was a permanent tibial tubercle with pain. On radiographic examination, an ununited ossicle was seen beneath the patellar tendon. Arthroscopy was performed through the standard low anterolateral and anteromedial portals close to the patellar tendon. Soft tissue at the retropatellar surface and the inflamed infrapatellar fat pad beneath the patellar tendon were debrided with a motorized shaver. Localization of the ununited ossicle was performed by use of an image intensifier. The ossicle was separated from the surrounding soft tissue with a motorized shaver and removed by use of a grasper. After excision of the ossicle, the inflamed surface of the retropatellar tendon was also debrided. The contouring of the irregular surface of the tibial tubercle was performed by use of a motorized bur. After 6 weeks, the patient returned to sports activities without any restrictions. This study showed that all of the described procedures might be done arthroscopically and sports activity may be allowed earlier.

[Venous thromboembolism prophylaxis in major orthopaedic surgery: A multicenter, prospective, observational study]. / Majör ortopedik cerrahilerde venöz tromboemboli profilaksisi: Cokmerkezli, prospektif, gözlem çalismasi.

OBJECTIVES: We investigated risk factors for venous thromboembolism (VTE), prophylaxis measures employed, and incidence of symptomatic deep venous thrombosis (DVT) and pulmonary embolism (PE) in patients undergoing major orthopaedic surgery (MOS). METHODS: An open, multicenter, prospective, observational study was conducted in 21 medical centers, comprising 899 patients. Of these, 316 patients (35.2%) underwent total hip arthroplasty (THA), 328 patients (36.5%) underwent total knee arthroplasty (TKA), and 255 patients (28.4%) underwent surgery for hip fractures (HF). Pharmacologic prophylaxis was employed in all the patients. RESULTS: Risk factors for VTE were seen in 73.2% of the patients, the most common being obesity (72%) and prolonged immobilization (36.3%). Low-molecular-weight heparin (91.1%) and fondaparinux (8.9%) were used for prophylaxis, which was short-term in 273 patients (30.4%) and long-term in 626 patients (69.6%). Mechanical prophylaxis was performed with compression stockings in 610 patients (67.9%) and by intermittent pneumatic compression in 67 patients (7.5%). During three-months of follow-up, symptomatic DVT and PE were seen in eight (0.9%) and four patients (0.4%), respectively. Mortality occurred in 10 patients (1.1%). Complications of major and minor bleeding were seen in eight (0.9%) and 40 (4.5%) patients, respectively. CONCLUSION: Effective VTE prophylaxis is associated with low risk of clinically apparent DVT and PE in MOS.

Early tunnel enlargement after arthroscopic ACL reconstructions.

The aim of this study was to evaluate the tunnel enlargement phenomenon after ACL reconstructions performed with hamstrings tendons fixed using the cross pin technique. Sixty-two knees in 62 patients were followed for two years to evaluate the possible clinical implications of the femoral and tibial tunnel enlargements noted after ACL reconstruction. The reconstructions were done with hamstring tendons using the cross-pin technique. Evaluation was based on calculated clinical scores (IKDC and Lysholm knee scores) and quantified by KT-1000 measurements. Sagittal and coronal plane computed tomography and conventional radiography were performed 3 days after operation and were repeated after 3 and 6 weeks, 6, 12 and 24 months, to assess early tunnel enlargement. Although it seems that tunnel enlargement after ACL reconstruction has no impact on the clinical results, long-term implications and potential need for revision surgery must be assessed. In this study, tunnel enlargement was noted fairly early after operation and was thought to be related with drilling of the tunnels. A possible solution to this problem may be drilling the tunnels to a diameter 1 mm smaller than the measured graft diameter, then to enlarge the tunnels to the graft diameter with the appropriate tunnel dilator.

[The effect of risedronate treatment on bone turnover markers in patients with hip fracture]. / Kalça kiriklarinda risedronat tedavisinin kemik yikim ürünlerine etkisi.

OBJECTIVES: The effect of risedronate treatment on bone resorption was investigated quantitatively by measuring N-telopeptide levels in urine of patients with hip fracture. METHODS: Forty-six women (mean age 75 years) who underwent surgical treatment for intertrochanteric or femoral neck fractures due to minor trauma were divided into two groups according to the order of presentation. One group (26 patients; mean age 77+/-5 years) received oral risedronate 5 mg/day after the fifth postoperative day, while the other group (20 patients; mean age 73+/-6 years) received no drug treatment. Patients who had been on treatment for Paget's disease or osteoporosis or those with renal failure were excluded. Urine samples were collected from all the patients on the second day of hospitalization and at the end of three months to measure N-telopeptide levels, one of the bone turnover markers, with the use of the Osteomark NTx ELISA laboratory kit. RESULTS: The mean urine N-telopeptide level decreased by 49.7% at the end of three months of treatment with risedronate (p<0.0001), whereas there was a 5.8% increase in the N-telopeptide level of the control group. The two groups differed significantly with respect to the levels of bone resorption at the end of three months (p<0.0001). CONCLUSION: Risedronate treatment was found effective in decreasing bone resorption and thus in reducing the risk for refractures in patients with hip fractures due to minor trauma.

[The use of arthroscopic debridement and viscosupplementation in knee osteoarthritis]. / Gonartrozda artroskopik debridman ve viskosuplementasyonun yeri.

OBJECTIVES: We investigated the effectiveness of arthroscopic debridement followed by viscosupplementation using different hyaluronic acid (HA) products in selected patients with knee osteoarthritis. METHODS: The study included 77 women (mean age 50+/-5 years; range 40 to 60 years) who had mild knee osteoarthritis according to the modified ARA (American Rheumatism Association) criteria and Ahlback classification. All the patients had degenerative meniscal tears. After three weeks from arthroscopic treatment (partial meniscectomy and debridement), the patients were randomly assigned to intra-articular injections of Na-hyaluronate (Orthovisc, n=38), streptococcal HA (Adant, n=21), and Hylan G-F 20 (Synvisc, n=18) given once a week for three weeks. Evaluations were made preoperatively, before and three weeks after injections using a patient satisfaction questionnaire, visual analog scale (VAS), and the WOMAC (Western Ontario and McMaster Universities) osteoarthritis index. RESULTS: All patients had significant improvement following both arthroscopic treatment and viscosupplementation (p<0.0001). Following injections, patient satisfaction (p<0.01), WOMAC and VAS (p<0.0001) scores were significantly improved in the Na-hyaluronate and Hylan G-F 20 groups, whereas the only significant change was in VAS scores in the streptococcal HA group. However, comparison of the three groups did not yield any significant difference with respect to patient satisfaction, WOMAC, and VAS scores (p>0.05). CONCLUSION: Our results suggest that arthroscopic debridement combined with viscosupplementation is an effective treatment option for selected patients with knee osteoarthritis.

Avulsion fracture of the posterior cruciate ligament at the tibial insertion in a child: a case report.

The posterior cruciate ligament (PCL) avulsion fracture from its tibial insertion is a very rare condition in children. An isolated avulsion fracture of PCL in a child and its repair by open reduction and internal fixation with a screw is reported.

A new capsuloplasty technique in open reduction of developmental dislocation of the hip.

A meticulous capsuloplasty is needed to maintain concentric reduction in the surgical treatment of developmental dysplasia of the hip (DDH). The authors present a new capsuloplasty technique that was named as 'reverse U-shaped capsuloplasty'. It was performed in 72 dislocated hips of 62 children with a mean age of 2.7 years. The reverse U-shaped flap, created in the redundant superolateral capsule was turned downwards, advanced medially, anteriorly and inferiorly and brought over the anteroinferior capsular incision. After a mean follow-up period of 3 years there was neither redislocation nor restriction of the hip joint motion in any hips.

Solitary cystic tuberculosis of long tubular bones in children.

Five children (mean age 3.4 years) with solitary cystic tuberculosis of proximal femur or proximal tibia were treated by surgical debridement and curettage combined with anti-tuberculosis anti-biotherapy. The mean follow-up period was 4.3 years and clinical and radiological healing was observed in all cases. It was concluded that solitary cystic tuberculosis of long tubular bones, which was a rare manifestation in children, should be kept in mind especially for metaphyseal lesions in the lower limbs and should be differentiated from several osseous lesions including infections and bone tumours.
