Methods Middle-aged patients with complaint of knee pain ongoing more than 6 months and failure in conservative treatment methods were included. Weight-bearing full extension, 30 and 45°of flexion radiographs were obtained. Joint space width was calculated on radiograms. Arthroscopy was performed to evaluate the chondral pathologies. Correlation analysis was performed. Results Fourty-three patients (18 female, 25 male) with a mean age of 44.6 (20-63) were included. Mean joint space width was 4.87 mm ± 1.45 (2-10) mm in medial and 5.43 mm ± 1.47 (1-9) in lateral on standing extension radiographs. In 30°flexion radiographs, mean joint space width was 4.33 mm ± 1.25 (1.5-7.5) in medial and 5.36 mm ± 1.69 (1-9) in lateral. In 45°flexion radiographs, medial joint space was 4.28 mm ± 1.59 (2-9) in medial and 5.15 mm ± 1.59 (1.5-9) in lateral. In arthroscopic evaluation, one knee had grade 1 (2.3 %), three knees had grade 2 (7 %), nine knees had grade 3 (20.9 %), and twelve knees had grade 4 (27.9 %) lesions in the medial compartment. In the lateral compartment, two knees had grade 3 (4.7 %) and one knee had grade 4 lesion (2.3 %). Radiological data did not correlate with the arthroscopic findings. Conclusion Standing knee radiographs do not correlate with the arthroscopic findings in the middle-aged population with chondral lesions in knee joint. Level of evidence Case series with no comparison group, Level IV.

The aim of this study is to compare the safety and efficacy of the apical pedicle subtraction osteotomy (PSO) technique with multiple posterior column osteotomies (PCO) in non-ambulatory patients with severe, rigid neuromuscular scoliosis. Neuromuscular scoliosis frequently causes intolerance to sitting due to pelvic obliquity, trunk decompensation and associated back and rib impingement pain which diminish the patient's functional capacity. In the case of rigid curves, spinal osteotomy techniques are occasionally required for effective correction. We retrospectively reviewed our patients with severe and rigid neuromuscular scoliosis with associated pelvic obliquity whom were treated with posterior instrumented fusion extending to pelvis with >1-year postoperative follow-up. We compared radiological and clinical results of PSO and multiple PCO techniques in severe rigid neuromuscular scoliosis with pelvic obliquity >15° in traction radiograph under ...

Various reconstructive techniques have been proposed to treat developmental dysplasia of the hip. However, the existing literature has not yet reached a consensus on the best technique regarding long-term survival. Objectives: This study aims to evaluate the long-term survival of uncemented hydroxyapatite (HA) coated acetabular components augmented with a femoral head autograft. Methods: We retrospectively reviewed the cases of 31 hips in 29 patients (24 female, 5 male, mean age 45.06 years) treated with HA-coated cementless components and femoral head autograft between 2000-2008 with a minimum follow-up of 10 years. Graft resorption, cup loosening and the anatomical hip centre were determined. Functional outcomes were calculated using the Harris Hip Scoring system. The survival of the acetabular component was evaluated using the Kaplan-Meier method. Results: In 24 hips (77,4%), we reconstructed the ...

METHODS In this study, we retrospectively reviewed 12 patients with displaced acetabular fractures treated surgically via the AIP approach. Patients were analyzed for Letournel's acetabular fracture classification, associated injuries, time to surgery, additional surgical procedures needed, perioperative and postoperative complications, radiologic and functional results. RESULTS Of the 12 patients, the male/female ratio was 1/2; the mean age was 40.5±16.2 (16-64) years. The mean follow-up time was 59.8±32.2 (12-124) months. Seven patients had both column fractures, three patients had anterior column + posterior hemitransverse fractures, one patient had transverse + posterior wall and one patient had anterior column fracture. The mean time to surgery was 6.6±4.4 (2-16) days. The mean intraoperative blood transfusion was 830 (300-2000) ml. Intra-operative and post-operative complications were noted in eight patients. The mean Merle d'Aubigné and Postel score was 14.5±2.7 (10-18). Six patients with an anatomical reduction of the fracture showed excellent/good functional and radiologic outcomes. Three patients with a non-anatomic reduction developed post-traumatic arthrosis that was treated with total hip arthroplasty. CONCLUSION AIP approach provides a satisfactory exposure for the surgical treatment of displaced anterior wall/column and both column acetabular fractures. Clinical outcome is directly related to the reduction quality. Patients with poor reduction are most likely to develop mid-term complications, such as hip joint arthrosis.

Allograft reconstruction provides good functional outcomes in restoration of normal pelvic anatomy. A 24-year-old male patient was reconstructed with an allograft-prosthesis composite after periacetabular resection due to pelvic chondrosarcoma. After four years, a two-staged revision with a custom-made pelvic prosthesis was performed due to septic failure. Successful radiographic and functional outcomes were achieved at two-year follow-up. In conclusion, we suggest a two-staged revision with a custom-made pelvic prosthesis as a satisfactory option in case of septic failure of allograft reconstruction after periacetabular resection.

Thirty patients with venous leg ulcers referred to a single chronic wound care unit with a minimum one year follow-up were included. Demographic features, co-morbidities, localization and characteristics of the ulcerated lesions, symptoms, arterial and venous Doppler ultrasound examination results, wound culture results, and outcomes of medical and surgical treatments were summarized. The treatment approach includes treating superficial and deep infections, obtaining tissue revascularization, compression, daily wound care, oral pentoxifylline, reconstruction of the major skin defects with split thickness skin grafts and hyperbaric oxygen therapy in refractory lesions. Mean age was 54 (32-85). Male to female ratio was 87%. Most common symptom was edema (83%). Mean size of ulcers were 20 cm² (4-45). Seven (23%) patients were hospitalized. Eighty % of patients had venous insufficiency. Most common isolated pathogen was P. aeruginosa (23%). Most common complication was osteomyelitis (5%). Hyperbaric oxygen therapy was applied to 3 patients. Split thickness grafts were used for the treatment of the skin defects in six (%20) patients. There was no recurrence of lesion in any patients at one year follow-up. Despite chronic lower extremity venous stasis ulcers are difficult to treat and related with a high risk of recurrence, it is possible to obtain good results with patient education and a systematic treatment approach.

METHODS In this prospective study, 46 knees of 23 consecutive ambulatory patients (15 boys and 8 girls; mean age=8.33 years; age range=5-12 years) with spastic diplegic CP with a gross motor function classification system level (GMFCS) II or III were included. The patients were then divided into 2 groups. In group I, there were 10 patients (4 boys, 6 girls; mean age=8.6±2), and combined release of ST in the myotendinous junction and SM in the myofascial junction, followed by aponeurotic release of SM were carried out. In group II, there were 13 patients (2 girls, 11 boys; mean age=8±2.35), and aponeurotic release of SM was done first and follo...

Methods: 24 New Zealand rabbits were grouped into two; control group (n = 8) and denervation group (n = 16). In-vitro passive mechanical tests were performed on healthy and denervated quadriceps muscles. Relaxation and creep test curves were fitted with the best fitting curve of the 'three-element fractional viscoelastic material model'. Following this eight material parameters characterizing the passive mechanical material properties were extracted for each specimen (E

[1] Posterior lateral menisküs kök yırtıklarına çoğunlukla genç erkek hastada ön çapraz bağ yırtığıyla beraber akut olarak rastlanır; travma anında, postero-lateral femur kondili ile tibia platosu arasında sıkışan lateral menisküste hasar meydana gelir. Bu bölgede, olaya tibia platosunda kemik iliği ödemi de eşlik eder (Şekil 1). Buna karşın, mediyal menisküs arka kök yırtıkları, sıklıkla dizde dejeneratif değişiklikleri olan orta yaş kadınlarda görülür. [2] Ön çapraz bağ yırtıklarının %7-12'sine posterior lateral M enisküs kök yaralanmalarının normal menisküs fonksiyonları üzerine etkisinin anlaşılmaya başlandığı son 10 yıllık süreçte, menisküs kök yırtıklarının tanı ve tedavisiyle ilgili önemli gelişmeler kaydedilmiştir. Mevcut çalışmalar ışığında, menisküs kök onarımıyla menisküs devamlılığı sağlanarak, aksiyel yüklenmelere karşı eklemi koruyucu etkisinin devam ettiği gösterilmiştir. Menisküs kök yırtıkları akut veya kronik olabilmektedir. Arka kökler hareket sırasında daha fazla yüklendiği için çoğunlukla arka kök yırtıkları görülürken, ön kök yırtıkları sıklıkla iyatrojenik yaralanmalardır. Ön kök yırtıklarının,

İmmatür femur başındaki eklem kıkırdağının derin katmanının beslenmesi subkondral damarlar yolu ile olduğundan, kemik nekrozunun yanı sıra, sekonder ossifikasyon merkezini çevreleyen kıkırdak tabakada da hücre ölümü gerçekleşir. [9] Ancak, LCP hastalığı, kendini sınırlayan bir hastalıktır. Femur başının vasküler dolaşımı zamanla kendiliğinden yeniden oluşur. Yeniden kanlanma iki yolla olur. İlk önce haftalar içerisinde tıkanık damarlar rekanalize olur. Yapılan bir çalışma, bu yolla oluşan yeniden kanlamanın daha dar bir bölgeden ve daha kısıtlı miktarda olduğunu ortaya koymuştur. [10] Daha sonra, aylar içerisinde femur başını besleyen yeni damarlar gelişir. Yeniden kanlanma ile birlikte nekrotik kemik rezorbe olarak yerine inflamatuvar hücreler, fibroblast-benzeri hücreler ve osteoklastlardan L egg-Calvé-Perthes (LCP) hastalığı, femur başı epifizinin vasküler beslenmesinin bozulması sonucu epifizin bir kısmı veya tamamında avasküler nekroz gelişimidir. [1,2] Histolojik çalışmalarda, femur başı epifizinde iskemik hasara bağlı doku nekrozu gösterilmiştir. [3] İmmatür memeli hayvanlarda femur başı kanlanmasının iyatrojenik olarak bozulduğu deneysel çalışmalarda, LCP hastalığında görülen radyolojik ve histolojik değişikliklerin benzeri oluşturulmuştur. [4] Ayrıca, LCP hastalarında yapılan selektif anjiyografi, sintigrafi ve manyetik rezonans görüntüleme çalışmalarında, lateral epifizeal arterin orijinine yakın bölümünde oklüzyon geliştiği gösterilmiştir. [5-7] Femur başının kanlanması durdurulduğunda meydana gelen iskemik nekrozun neden olduğu ilk histolojik değişiklikler; kemik iliğinde yaygın hücre apoptozu, kemik iliği stromasında düzensizlik ve trabeküler kemikte osteoblast kaybı olarak özetlenebilir.

We report the outcomes and complications of 7 patients who underwent limb salvage following type II or type II, III pelvic resection and reconstruction using a saddle prosthesis or custom-made hemipelvic prosthesis. In our opinion, reconstruction using custom-made prostheses is better than placement of saddle prostheses because of a lower risk of complications and improved functional outcomes.
