Aims

We reviewed all patients who sustained a fracture of the hip and were treated in Northern Ireland over a period of 15 years to identify trends in incidence, the demographics of the patients, the rates of mortality, the configuration of the fracture and the choice of implant.

Patients and Methods

Since 01 January 2001 data about every fracture of the hip sustained in an adult have been collected centrally in Northern Ireland. All adults with such a fracture between 2000 and 2015 were included in the study. Temporal changes in their demographics, the mode of treatment, and outcomes including mortality were analysed.

Introduction: Intracapsular femoral neck fractures in adults under 65 years old are associated with significant complications such as avascular necrosis of the femoral head and non-union. Timing of surgery remains controversial, with some studies suggesting that early surgical fixation reduces the rate of these complications. Presently the policy in this Fracture Unit remains early fixation (target less than twelve hours). The purpose of this study is to determine if this twelve hour target is being achieved and if not, where the delays are occurring.

Methods: A retrospective case-note and data analysis was performed on all patients aged under 65 who underwent internal fixation of displaced intracapsular femoral neck fractures (Garden III/IV) between 31/12/06 and 31/12/07. The following data was collected; time of injury to presentation at health service, time from presentation at health service to admission at treating hospital, time of admission at treating hospital to time of surgery and overall time from injury to surgery. The main causes of delay were also determined.

Results: In the one year period, there were 37 young adults with displaced intracapsular femoral neck fractures, with a mean age of 52.57 years. There were 23 females (62.2%) and 14 males (37.8%).

We also present the reasons for delay at each stage including transfer delays, medical delays and limited emergency theatre availability.

Discussion: Early operative fixation of young femoral neck fractures remains controversial. In this unit where it is advocated, the median time from injury to fixation is 22.18 hours. By reducing transfer times, increasing emergency theatre availability and improving efficiency of patient preparation for theatre at ward level, the twelve hour targets will be much more attainable.

Background: Short-term cure rates of two stage revision for infection after TKR are approximately 90%. Little is known about the long-term reinfection-free survival or the mechanical durability of the reimplanted prostheses. The purpose of the study is to evaluate the mid to long term results of this technique with regards to persistence of infection, clinical and radiographic results. The hypothesis is that the success rate of the technique is maintained through long term follow-up, with a low rate of recurrent infection and mechanical implant failure.

Methods: from January 1990 to august 2002, 124 two stage revision TKR for infection were performed at Our Institution with mean follow-up of 9,8 years (5 to 17,5).

The clinical results were evaluated with SF12, WOMAC, and KSCRS performed preoperatively and postoperatively at 5 and 10 years. A radiographic analysis was performed using x-rays of the last available follow-up.

Results: the WOMAC and KSCRS significantly improved at the 5 years follow-up decreasing slightly at 10 years. The SF12 postoperative variation was not significant. The radiographic results showed possible loosening of the tibial or femoral components on 17% and 12% of patients respectively. There were 17 reoperations, 10 of which for persistent infection (85% of survival at 10 years).

Discusssion and conclusion: we are encouraged by the rate of eradication of infection at 10 or more years in these difficult cases. The long term clinical and radiographic results are satisfactory. The study supports the sustained use of this technique for infected total knee arthroplasties.

Aim: The purpose of this study was to report our experience mid to long-term results of hybrid cement fixation in revision total knee arthroplasty.

Methods: Patients who underwent revision total knee arthroplasty using a hybrid cement technique (press-fit diaphyseal fixation and cemented metaphyseal fixation) with a titanium fluted revision knee implant were reviewed. There were 127 patients. Mean age at surgery was 71 years (range 41–94 years). There were 56 males and 71 females. Mean follow-up was 5 years (range, 2–12 years). A Kaplan-Meier survivorship analysis using an end-point of revision surgery or radiographic loosening was employed to determine probability of survival at 5 and 10 years.

Results: 127 patients (135 knees), 31 patients (36 knees) died and 2 patients (2 knees) were lost to follow-up. Six patients (six knees) were revised at a mean of 3.5 years (range 1–8 yrs). Of the 6 revisions, two were for re-infection, two were for (MCL) instability, and two were for aseptic loosening. Mean Knee Society clinical and functional scores were 86 and 55 points, respectively. The mean range of motion was 108 degrees. End of stem pain was not reported in this group of patients. Kaplan-Meier survivorship analysis revealed a probability of survival free of revision for aseptic loosening of 98% at 12 years.

Discussion: The results of this study suggest that the use of a hybrid cement technique in revision knee arthroplasty can provide good mid to long-term results. Radiographic analysis has shown continued satisfactory appearances regardless of constraint, stem size and augments. Our experience has shown that the survivorship of a hybrid fixation technique for revision knee arthroplasty is comparable to reported long-term survivorship of cemented revision knee arthroplasty.

We followed prospectively 69 patients with 78 proximal femoral allografts performed for revision of total hip arthroplasty for an average of 36 months (range 29 to 68). Large fragment proximal femoral allografts and cortical strut allografts were successful in 85%. Grafts smaller than 3 cm in length (calcar grafts) were clinically successful in 81%, but 50% underwent significant radiographic resorption. We conclude that large proximal femoral allografts and cortical strut allografts provide dependable reconstruction of bone stock deficiencies during revision total hip arthroplasty.
