Our data show that PLT can be an appropriate autograft source for ACL reconstruction, avoiding potential complications of autografts obtained from the knee region.
We treated 15 hips (15 patients) with developmental dysplasia by a single-stage combination of open reduction through a medial approach and innominate osteotomy. The mean age of the patients at the time of operation was 20 months (13 to 30). The mean follow-up period was 9.6 years (4 to 14). At the final follow-up, 14 hips were assessed clinically as excellent and one hip as good. Radiologically, ten hips were rated as class I, four as class II and one as class III according to the criteria of Severin. No avascular necrosis was seen. No patient required subsequent surgery. Our results indicate that satisfactory results can be obtained with the single-stage combination of open reduction by the medial approach and innominate osteotomy for developmental dysplasia of the hip in a selected group of children older than 12 months. To our knowledge, no similar combined technique has been previously reported.
Metal-on-metal dysplasia cup total hip arthroplasty for hip osteoarthritis secondary to developmental dysplasia of the hipGelişimsel kalça displazisine bağlı kalça osteoartriti için metal-metal displazi cup total kalça artroplastisi Developmental dysplasia of the hip (DDH) is the most common cause of secondary hip osteoarthritis. Dysplasia includes deformities such as hypoplastic acetabulum, narrow femoral intramedullary canal, leg-length discrepancy, shortened muscles around the hip, and abnormal neurovascular structures. All of these anatomical abnormalities require a challenging surgical operation in the treatment of dysplastic hips.In this study, we aimed to evaluate the clinical and radiological results of metal-on-metal dysplasia cup total hip arthroplasty (THA) for hip osteoarthritis secondary to DDH. İki hastada ameliyat sonrası siyatik sinir arazı gelişti. Bir hastada ameliyattan bir yıl sonra tekrarlayan çıkık meydana geldi. Ortalama cup inklinasyonu 46.5° idi (dağılım 42°-51°). Sekiz hastada heterotopik osifikasyon meydana geldi. Hiçbir hastanın asetabüler ve femoral komponenti anlamlı şekilde yer değiştirmedi veya çökmedi. Hiçbir implant revize edilmedi. Sonuç: Gelişimsel kalça displazisinde displazi cup TKA'nın erken dönem klinik ve radyolojik sonuçları tatmin edicidir.Anahtar sözcükler: Gelişimsel kalça displazisi; metal-metal kalça protezi; total kalça artroplastisi.Objectives: This study aims to evaluate the clinical and radiological results of metal-on-metal dysplasia cup total hip arthroplasty (THA) for hip osteoarthritis secondary to developmental dysplasia of the hip (DDH). Patients and methods: Between May 2009 and October 2011, THA was performed on 27 hips (7 Crowe type II, 9 Crowe type III, 11 Crowe type IV) of 22 patients (2 males, 20 females; mean age 43 years; range 25 to 63 years) with hip osteoarthritis secondary to DDH. All patients were evaluated clinically and radiographically. Results: Average follow-up period was 34.2 months (range 24-53 months). While mean Harris hip score (HHS) was 43 (range 30 to 72 points) preoperatively, it was 92 (range 87 to 98 points) at final follow-up. Two patients developed sciatic nerve palsy postoperatively. Recurrent dislocation occurred in one patient one year after the operation. Mean cup inclination was 45.6° (range 42°-51°). Heterotopic ossification developed in eight patients. No patient's acetabular and femoral component migrated or subsided significantly. None of the implants was revised. Conclusion: Early clinical and radiological results of metalon-metal dysplasia cup THA in DDH are satisfactory.Keywords: Developmental dysplasia of the hip; metal-on-metal hip prosthesis; total hip arthroplasty.
To date, 23 cases with osteoid osteoma (OO) including multiple nidi in single bone have been reported in the world literature. A case report of an 18-year-old boy with an OO on his left femoral neck, which contained double nidi is presented. Plain radiography, computed tomography (CT) and magnetic resonance imaging (MRI) of the proximal femur showed OO with a multicentric nidus. Bone scintigraphy demonstrated increased activity in the left femoral neck region. The tumor was removed with curettage and shaving using lateral approach. The patient was asymptomatic for 5 years after surgery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
