“…2 There is a recent trend towards cementless fixation of the cup, especially in young patients, 3 but there are few data which support this. 5,6,17,[28][29][30] There have been disappointing results of the use of threaded screw-ring prostheses. 31,32 A controlled, randomised study using roentgen stereophotogrammetric analysis showed no major difference in terms of skeletal fixation between a Harris-Galante acetabular component inserted without cement and an all-polyethylene Charnley acetabular component fixed with cement, 33 but the maximum duration of follow-up was only 49 months.…”

We reviewed 264 consecutive primary total hip replacements in 244 patients in which the Harris-Galante I porous-coated acetabular component had been used. The mean follow-up was 95 months (69 to 132). In 221 arthroplasties a 32 mm ceramic head had been used, and in the other 43 one of cobalt-chrome alloy. There were 124 women and 120 men with a mean age at operation of 56.8 years (21 to 83).Survival analysis of the acetabular components was performed using the following definitions of failure: 1) infection; 2) removal because of aseptic loosening; 3) removal for any cause; and 4) a worst-case analysis including removal of the cup or infection or loss to follow-up.Two well-fixed cups had been removed because of deep infection and three, similarly sound cups had been exchanged at the time of femoral revision. None of the acetabular components had required revision for aseptic loosening. After 11 years survival was 97.7% using the worst-case criterion. Radiological analysis of 187 acetabular components at a mean of 82 months (41 to 132) revealed no case of aseptic loosening. Pelvic osteolysis was seen in only one patient, but was not progressive and showed signs of regression.The results using these acetabular components are encouraging but the need for regular follow-up remains since complications such as significant wear of the liner, massive osteolysis of the pelvis, aseptic loosening and late infection may increase in the second decade.

“…In the reported patients, the dislocation occurred in the infantile [6] or in the adult [5,[7][8][9]11] age, after a fall [7,9] or after a trivial trauma, or spontaneously [5,6,8,11]. In all the patients the presence in the joint of material associated with neurofibromatosis was reported after the histological examination of the biopsy -or it was only suggested based on radiographic, MRI and CT imaging.…”

“…The analysis of the few reported cases of pathological dislocation of the hip [5][6][7][8][9][10][11] shows that the dislocation is generally due to the mechanical action of the growth of a neurofibroma inside the joint. In the reported patients, the dislocation occurred in the infantile [6] or in the adult [5,[7][8][9]11] age, after a fall [7,9] or after a trivial trauma, or spontaneously [5,6,8,11].…”

Pathological dislocation of the hip in neurofibromatosis: a case report

2008

The Authors report the case of a 28-year-old patient with type 1 neurofibromatosis, who presented a pathological dislocation of the hip. This event was preceded by the development of a neurological pattern of spastic paraparesis and decreased pain sensation in both lower limbs, secondary to the progression of a dystrophic kyphoscoliosis. Pathological dislocation of the hip in neurofibromatosis has been reported in the literature as a consequence of intra-articular growth of neurofibromas. Conversely, in the case described here, clinical and radiographic features and the absence of neurofibromas in the joint, verified by means of radiographic and histological examinations, suggested the diagnosis of neuropathic arthropathy. The treatment of hip dislocation should be differentiated according to the aetiology, given the underlying articular instability in cases of neuropathic arthropathy.

“…Infiltration of a joint and its structures by tissue associated with neurofibromatosis has been described in association with dislocation of the hip in children. 8,[14][15][16] This was accompanied by bony changes including narrowing of the neck of the femur, acetabular dysplasia, erosion of the acetabulum and deformities of the pubis and ischium, all caused by the invasion of neurofibromatosis tissue. McCann et al 18 have described an adult male with neuropathic arthropathy of the knee due to involvement of a spinal nerve by neurofibromatosis leading to an insensitive knee.…”
