We undertook a review of the literature relating to the two basic stem designs in use in cemented hip replacement, namely loaded tapers or force-closed femoral stems, and the composite beam or shape-closed designs. The associated stem fixation theory as understood from in vitro studies and finite element modelling were examined with reference to the survivorship results for each of the concepts of fixation.

It is clear that both design principles are capable of producing successful long-term results, providing that their specific requirements of stem metallurgy, shape and surface finish, preparation of the bone and handling of the cement are observed.

The operative treatment of lesions of the anterior cruciate ligament (ACL) in athletes has been widely advocated and performed. We have investigated the outcome of non-operative management in a lower-demand, general population. We reviewed a consecutive group of 228 patients, which excluded professional and high-level athletes, for two to 12 years after an ACL lesion had been diagnosed by arthroscopy.

There was a low incidence of secondary ACL and meniscal surgery, 5.4% and 3.5% respectively, and all these procedures were performed during the first three years after the ACL injury.

We studied a subgroup of 109 patients with follow-up of at least five years (mean 8.5 years) and evaluated them using the IKDC score. The general outcome was reasonably satisfactory, with 23% in grade A, 50% in grade B, 21% in grade C and only 6.4% in grade D. We found no statistically significant prognostic effect within this group as regards age, activity levels, or the incidence of associated lesions.

In a prospective trial, biodegradable polyglycolic acid rods were compared with Kirschner wires for fixation of wrist fractures (Frykman types I, II, V and VI). Fifteen patients were randomly assigned to each treatment group. There was no significant difference between the groups with regard to age, sex ratio and fracture type. Kapandji's pinning technique was used in all cases. There were no significant differences in the results obtained in both groups at final follow-up. At three months and six months the functional results of the Kirschner-wire group were, however, significantly better (p < 0.05), due to numerous transient complications from foreign-body reactions to the polyglycolic acid rods. The use of polyglycolic acid rods is therefore not recommended for the fixation of distal radial fractures.

We have investigated a prospective series of 100 acute traumatic haemarthroses of the knee in a general non-athletic population. All the patients had normal radiographs and an aspiration which confirmed the haemarthrosis, before undergoing ligament testing and an arthroscopic examination under anaesthesia. Only one patient had no serious pathology; in the other 99 a total of 193 lesions were recorded. Thirty knees had only one isolated lesion, 69 had combined lesions. This study confirms the serious nature of an acute traumatic haemarthrosis of the knee, even in non-athletic patients.

This paper presents four patients with injuries to the thoracolumbar spine assessed by computerised tomography. This technique enabled an easy, quick and accurate diagnosis to be made, avoiding dangerous manipulation of the patient. The scans were analysed using the anatomical classification of Louis to evaluate the instability of the lesions. Control CT scans were used to monitor progress and to provide an accurate prognosis within acceptable limits of irradiation.
