We have reviewed a consecutive series of six professional footballers who presented with intractable hip pain which was attributed at arthroscopy, to an anterior acetabular labral tear with adjacent chondral damage. The location and type of labral tear were identical for each patient. There was no evidence of acetabular dysplasia. A variable area of chondral damage was associated with the labral tear. All unstable tissue was resected. Five returned to professional football at the highest level. Acetabular labral pathology should be included in the differential diagnosis of footballers with hip or groin pain. Arthroscopy of the hip is an appropriate method of diagnosis and treatment and minimises the length of rehabilitation required.
Early failures have seen titanium fall from favour as a material for cemented femoral stems. Between 1989 and 1994, we performed a prospective review of a consecutive series of 122 cemented total hip replacements using the Ultima straight textured titanium stem, and report the five- to ten-year clinical and radiological outcomes. There were no revisions for loosening of the femoral stem. Revision surgery was undertaken for other reasons such as dislocation, infection and loosening of the cup in 7.3%. Of those patients without revision all but two were satisfied with their hip, with 74% graded good or excellent using a modified Harris hip score. Radiological assessment revealed probable loosening in two. Although slight vertical subsidence was found in one-third of patients it had not progressed to loosening. It is not clear whether this represents debonding. Non-progressive radiolucent lines (1 to 2 mm) were present in zone 1 at the cement-prosthesis interface in 14.7%. Calcar resorption and hypertrophy around the distal stem were not often seen. With 97% survival at a mean of 7.5 years, the medium-term results of this specific cemented titanium stem are reassuring so far, but we are concerned about debonding and future failure.
We have compared the findings of MRI with those of hip arthroscopy in 23 hips in young adults with hip pain. Large deep cartilage deficiencies on the acetabulum or femoral head, the percentage of femoral head cover, and the presence of marginal osteophytes seen on MRI correlated well with those seen at arthroscopy, but chondral softening, fibrillation, or partial-thickness defects less than 1 cm in diameter were less consistently detected by MRI. Osteochondral loose bodies and labral tears were not well demonstrated by MRI, but were readily identified and treated at arthroscopy. Arthroscopy of the hip is a useful investigation for hip pain in young adults especially when standard non-invasive MRI fails to provide a clear diagnosis.
We describe a simple, retroperitoneal approach for the removal of acetabular components that have migrated into the pelvis. The dense fibrous tissue layer which surrounds the implant protects the iliac vessels during removal of the cup by this method.
We report the contamination rate in the Cambridge bone bank of 35 consecutive allograft specimens, all harvested in a clean-air environment, using a strict aseptic technique and antibiotic cover. Five of 27 femoral heads taken from living donors and three of eight massive allografts taken from cadavers were found to be contaminated. The contaminated femoral heads were discarded. All massive allografts were rendered sterile by gamma-irradiation. It is important to exclude bacteriological contamination of harvested and banked bone.
A review of 77 neonates who presented with congenital talipes equinovarus over a seven-year period revealed an increase in the condition amongst babies born in the winter quarter. This finding was particularly apparent among the less severe cases of club-foot. Possible reasons for this seasonal variation are discussed.
A prospective study was made over a three-year period of 900 consecutive unilateral Colles' fractures. The radiographic features at the time of fracture, after reduction and one week later were measured and correlated with grip strength and range of movement at three years. The most significant radiographic feature to influence the outcome was the presence of shortening of the radius one week after reduction of the fracture. Persistent dorsal tilt, radiocarpal joint involvement and ulnar styloid fracture were each associated with reduced range of movement, but had no effect on grip strength. Extension of the fracture into the distal radio-ulnar joint was associated with reduced grip strength but had no effect on range of movement. Radial tilt of the radial fragment did not correlate with any aspect of the result after three years.
Of 135 consecutive patients admitted with subtrochanteric fractures of the femur, 104 were studied; half had internal fixation with a Zickel nail and half had a nail-plate device. Fractures treated with a Zickel nail had significantly less blood loss during operation and took less time to walk with full weight-bearing, but the incidence of technical error at operation was higher. Errors included malalignment of the cross-pin, penetration of the femoral cortex and comminution of the greater trochanter. There was mechanical failure within one year of surgery in 17% of the nail-plate series but no implant failures in the Zickel nail group within the same period. The total time spent in hospital was similar in both groups. The Zickel nail provides better fixation for subtrochanteric fractures than a simple nail-plate but, because of technical difficulty, its use should be reserved for surgeons of reasonable experience.
