Acute urinary retention is a common complication after lower limb arthroplasty. The aim of our study was to assess whether the International Prostate Symptom Score (IPSS) and other patient related factors could predict the likelihood of patients developing urinary retention after lower limb arthroplasty. We have also reviewed the literature on this subject. ⋯ Of all the parameters studied, age was the only factor that correlated significantly with development of urinary retention. The risk factors for progression of benign prostatic hyperplasia could all be considered as factors for the development of this complication. However, apart from age more than 70 years, it is not practical to use the other parameters.

Fracture healing is a complex process in which mechanical forces are essential for the regeneration of bone tissue. Mechanical loading can induce osteogenesis through the process of mechanotransduction. ⋯ The role of mechanosensors, loading-induced interstitial fluid flow, streaming potentials, the biophysical environment of the fracture gap and the significance of timing, strains and distribution of mechanical stimulation in long bone fractures are reviewed. Remodelling and biomechanical concepts of fracture healing are discussed from a clinical perspective.

Patients with trapeziometacarpal joint arthritis stage II or III (according to Dell) and no benefit from non-operative therapy were selected to undergo joint arthroplasty. We performed 32 arthroplasties for first carpometacarpal arthritis in 27 patients using a cementless total trapeziometacarpal joint prosthesis. We undertook a prospective cohort study and evaluated the clinical results of total joint arthroplasty after an average of 39 months. ⋯ In all our patients Vitamin C 500 mg daily was started two days before surgery and continued during 50 days. There were no cases of CRPS under vitamin C prophylaxis. These results justify further investigation in a randomised clinical trial.
