Aims

The aim of this study was to investigate the outcome of periprosthetic fractures of the humerus and to assess the uniformity of the classifications used for these fractures (including those around elbow and/or shoulder arthroplasties) by performing a systematic review of the literature.

Methods

A systematic search was conducted using the National Institute for Health and Care Excellence Healthcare Databases Advance Search. For inclusion, studies had to report clinical outcomes following the management of periprosthetic fractures of the humerus. The protocol was registered on the PROSPERO database.

Between 1990 and 1996 we performed 20 consecutive ulnohumeral arthroplasties for primary osteoarthritis of the elbow.

The outcome was assessed using the Disabilities of Arm, Shoulder and Hand Score (DASH) and the Mayo Elbow Performance Score (MEPS) at a mean follow-up of 75 months (58 to 132). There were excellent or good results in 17 elbows (85%) using the DASH score and in 13 (65%) with the MEPS (correlation coefficient 0.79). The mean fixed flexion deformity had improved by 10° and the range of flexion by a mean of 20°.

In 16 elbows (80%) the benefits of surgery had been maintained, and of 16 patients working at the time of operation, 12 (75%) had returned to the same job.

There was no correlation between radiological recurrence of degenerative changes and the amount of fixed flexion deformity, the flexion arc, or the elbow scores.

We aimed to determine whether the EBRA method had greater precision and sensitivity for measuring implant migration following total hip arthroplasty (THA) than direct plain radiographic techniques using modern measuring tools.

Short-term precision was evaluated in 20 subjects following THA. Consecutive, standardised radiographs of the hip were performed on the same day after repositioning. Prosthetic cup and stem migration were measured from the plain radiographs using a digital calliper following methods described by Ianotti, Malchau, Nunn, Sutherland and Wetherall, and compared to those made using EBRA. Precision was expressed as 95% confidence interval (95%CI = 1.96x Std.dev.). 10 subjects were then followed prospectively with standardised plain radiographs at baseline, 6,12 and 26 weeks after THA. Migration measurements made using EBRA were compared to those made using the most precise plain radiographic method.

The 95%CI of all EBRA cup and stem measurements was ±1mm or smaller. Only the Sutherland method had a similar level of precision (95%CI ±1.11 to 1.28 mm: F-Test P> 0.05; all other method comparisons with EBRA P< 0.05). In the longitudinal study cup cranial migration of 0.53 mm (SEM 0.19) and stem subsidence of 1.53 mm (SEM 0.19) were detected using EBRA (2-way ANOVA by rank; P< 0.05 and P< 0.001 respectively). No statistically significant migration of the cup or stem was detected using the Sutherland method.

The EBRA method is a precise method for describing implant migration in small groups of patients in the early period following THA, and manual methods lack sufficient precision to be used for this purpose.
