  ABSTRACT: We have reviewed 54 patients who had undergone 61 total hip replacements using bulk femoral autografts to augment a congenitally dysplastic acetabulum. There were 52 women and two men with a mean age of 42.4 years (29 to 76) at the time of the index operation. A variety of different prostheses was used: 28 (45.9%) were cemented and 33 (54.1%) uncemented. The graft technique remained unchanged throughout the series. Follow-up was at a mean of 8.3 years (3 to 20). The Hospital for Special Surgery hip score improved from a mean of 10.7 (4 to 18) pre-operatively to a mean of 35 (28 to 38) at follow-up. The position of the acetabular component was anatomical in 37 hips (60.7%), displaced less than 1 cm in 20 (32.7%) and displaced more than 1 cm in four (6.6%). Its cover was between 50% and 75% in 34 hips (55.7%) and less than 50% in 25 (41%). In two cases (3.3%), it was more than 75%. There was no graft resorption in 36 hips (59%), mild resorption in 21 (34%) and severe resorption in four (6%). Six hips (9.8%) were revised for aseptic loosening. The overall rate of loosening and revision was 14.8%. Overall survival at 8.3 years was 93.4%. The only significant factor which predicted failure was the implantation of the acetabular component more than 1 cm from the anatomical centre of rotation of the hip.

  ABSTRACT: We examined the pelvic radiographs of two groups of patients (more than 12 years of age) from six medical centres. Hip dysplasia was considered to be present if Shenton's line was broken and more than one third of the femoral head was revealed to be uncovered in an antero-posterior radiograph of the pelvis. Patients with hip dysplasia due to teratological or neurological causes were excluded. There were 291 patients with treated or untreated hip dysplasia in the dysplastic group. The control group of 415 individuals was collected from consecutive outpatients (with a pre-set standardised female/male ratio) for whom an antero-posterior radiograph of the pelvis had been made in one of two medical centres and which did not disclose any abnormality of the hip joints. The aim of the study was to assess the co-existence of hip dysplasia and occult spinal dysraphism. Radiographs of all patients were examined, and any partial or complete defect of the posterior vertebral arch was recorded. In the dysplastic group, a defect was recorded in 23% (67/291) radiographs and in the control group in 12% (48/415). In both groups, L5 and S1 were the most commonly recorded sites with a defect. In the dysplastic group, a defect was recorded in 56/190 females and in the control group in 30/302 females. In males, there was no significant difference between the recorded findings in the two groups. In females with hip dysplasia, occult spinal dysraphism seems to be fairly common.

• Article: Fibrocartilaginous mesenchymoma of the distal femur: case report and literature review.

  G Gedikoglu, M C Aksoy, S Ruacan
  [show abstract] [hide abstract]
  ABSTRACT: A case of a 9-year-old boy with fibrocartilaginous mesenchymoma located in the distal femur is presented. Fibrocartilaginous mesenchymoma is a rare tumor. There have been 17 cases reported since 1984. The presenting complaint was pain and local discomfort. Radiological examination showed lytic and sclerotic lesions located in the distal femur. Magnetic resonance imaging showed that there was no soft tissue expansion. Differential diagnosis included fibrocartilaginous dysplasia, dedifferentiated chondrosarcoma, desmoplastic fibroma, fibrosarcoma and low-grade osteosarcoma. The diagnosis of the tumor in a state hospital would not have been possible. Wide resection of the tumor and resection arthrodesis with an intramedullary nail has yielded good results. The patient has been disease free for 4 years. Pathological diagnosis of this very rare tumor may be challenging; the treatment should be wide resection of the tumor.

• Article: Erythropoietin for autologous blood donation in total hip arthroplasty patients.

  M C Aksoy, A M Tokgozoglu
  [show abstract] [hide abstract]
  ABSTRACT: Forty patients who were scheduled for a total hip arthroplasty were enrolled in a prospective study and were randomly divided into two groups. Group 1 received recombinant human erythropoietin (300 U/kg twice a week), and group 2 received placebo. The medication was started 2 weeks before the operation, and only one dose of medication was given after the operation. Autologous blood was administered at the same time as the medication until the hemoglobin level sank to 10 g/dl. Forty-eight and 49 units of autologous blood were collected in group 1 and group 2, respectively. Intraoperative homologous blood was transfused only to patients in group 2. Seven and 13 units of allogenic blood were transfused into group 1 and group 2 patients during the postoperative period, respectively. There were no any significant differences between the groups in terms of early postoperative hemoglobin level and amount of autologous blood collected. However, the increase of the reticulocyte count in patients who received erythropoietin was significantly higher than in the group 2 patients. The study showed that short-term and low-dose erythropoietin usage strongly stimulates the bone marrow. Erythropoietin administration and preoperative autologous blood donation diminished the total units of allogenic blood required during the intraoperative or postoperative period. Autologous blood administration without concurrent erythropoietin did not stimulate the bone marrow adequately.

  Article: Subtrochanteric valgus-extension osteotomy for neglected congenital dislocation of the hip in young adults.

  M C Aksoy, Y Musdal
  [show abstract] [hide abstract]
  ABSTRACT: Thirty-five patients with unilateral or bilateral neglected congenital dislocation of the hip (CDH) were treated with subtrochanteric valgus-extension osteotomy between 1975 and 1992. There were 29 females and 6 males in the group. A total of 50 osteotomies was performed. The mean age of the patients was 22 years; the mean follow-up was 7 years. Before operation, the main complaints were pain and gait abnormalities. Leg-length discrepancy was another problem, especially for unilateral cases. The main indication for the operation was pain. This pelvic support osteotomy was performed to correct the instability of the hip and as a result of this to relieve pain. Patients were retrospectively evaluated based upon Harris Hip Score and self-evaluation. The mean Harris Hip Score was 49 before operation and improved to 72 after the operation. Alleviation of the pain was the most significant functional outcome of the treatment. It was also noted that limping could be improved if an adequate rehabilitation program was followed. We conclude that in neglected CDH cases with pain, limping and lumbar hyperlordosis in the young adult, a subtrochanteric valgus-extension osteotomy can give satisfactory results.

  ABSTRACT: A report of a rare complete dislocation of the first lumbar vertebra without fracture in a 6-year-old girl. To describe a rare traumatic lesion in children. Although there has been a report of posterior dislocations of vertebra without fracture accompanied by anterior apophyseal splitting in young cadavers, all in the cervical region, to date, there has not been a reported clinical case of vertebral dislocation in the thoracolumbar region in a child. A 6-year-old girl, while playing on a farm, had her hair caught in the wheel of a sugar beet harvesting machine. She was referred with incomplete paraplegia. Radiologic examination showed an L1-L2 dislocation with no fracture. She was treated surgically using a modified Luque frame with sublaminar wires. Six months after injury, the patient had no neurologic deficit and was living an entirely normal life. Radiographs showed a perfect alignment of the thoracolumbar spine. At the 26-month follow-up, no radiologic abnormalities were observed, other than minimal end-plate sclerosis. Magnetic resonance images obtained after the removal of the implants showed no structural abnormalities in the vertebral column except disc narrowing at all instrumented levels, secondary to posterior fusion. To date, this is the first case of dislocation of the thoracolumbar spine in children. It is further notable because the neurologic deficit was incomplete, although there were striking radiologic abnormalities.

  ABSTRACT: The authors report a fracture of an ossified Achilles tendon in a 44-year-old male patient who was admitted to the hospital after a minor injury with pain on the posterior aspect of his left calf. Examination disclosed a fracture of the ossified Achilles tendon. Plain roentgenogram and MRI confirmed Achilles tendon ossification and fracture at the distal one-third of the tendon. Surgical treatment with excision of the ossified mass and reconstruction with an Achilles tendon flap was performed. After two years, the patient has quite good function, and MRI shows healing of the tendon.

  ABSTRACT: Treatment of congenital dislocation of the hip (CDH) by closed reduction and immobilization in the hip spica cast is one of the accepted methods for use in patients under one year of age. We report 74 congenitally dislocated hips treated with premanipulation skin traction, closed reduction under anesthesia, adductor tenotomy and immobilization in the hip spica cast. Satisfactory results were obtained in 60 hips. In seven hips, avascular necrosis of the capital femoral epiphysis was observed with careful management, closed reduction and immobilization in a spica cast provides good results for treatment of CDH.

• Article: Arthroscopic partial resection of the discoid meniscus in children.

  O A Atay, M N Doral, M C Aksoy, O Tetik, G Leblebicioğlu
  [show abstract] [hide abstract]
  ABSTRACT: Thirteen children with 14 lateral discoid menisci were reviewed at an average follow-up of 2.7 years. Their average age at the time of the operation was 12.8 years. Most of the children had vague and intermittent painful symptoms, and the classical "clunk" was demonstrable in nine of the 13 patients in clinical examinations. Thirteen children underwent arthroscopic partial meniscectomy for symptomatic discoid lateral meniscus, by performing partial resection. This procedure, modifying the discoid lateral meniscus to the normal semilunar shape, was indicated only when the capsular attachment was intact. The results were excellent both clinically and radiologically. Furthermore, rehabilitation time was considerably shorter than the time required after open procedures. Arthroscopic discoid meniscus surgery performed by experienced and skilled hands gives better results. According to the literature and our experiences, it is better to perform open techniques in patients with stiff knees. Additionally, it is technically feasible to use small joint instruments in the pediatric age group.
