Introduction. Many patients with displaced intracapsular femoral neck fractures (IFNF) are treated with hemiarthroplasty (HA) which has been shown superior to internal fixation(IF) the first year after injury. Long term results, however, are sparse. Methods. A total of 222 consecutive patients above 60 years, including mentally disabled, with IFNF were randomized to either internal fixation with two parallel screws or hemiarthroplasty, and operated by the surgeon on call. After 5 years, 68 of the 70 surviving patients accepted a follow-up visit. The reviewers were blinded for initial treatment. Results. The mean survival of the groups was similar. Only 12 (of 31) patients in the IF group still had their native hip joint at five years. Harris Hips score was 70.0 ± 3.5 and 70.4 ± 3.4 in the IF and hemiarthroplasty group, respectively (p=0.9). Eq5d index was in the IF group 0.56 ±0.08 and in the hemiarthroplasty group 0.45 ± 0.7 (p=0.3). Barthel ADL index was split into good function (score 95 or 100) and reduced function (score below 95). Of the patients in the internal fixation group, 42 % reported good function, corresponding number in the arthroplasty group was 52 % (p=0.4). After two years, there were 44 (42%) hips with a
Vancouver B fractures around a cemented polished tapered stem (CTPS) are often treated with revision arthroplasty. Results of osteosynthesis in these fractures are poor as per current literature. However, the available literature does not distinguish between fractures around CTPS from those around other stems. The aim of our study was to assess the clinical and radiological outcome of open reduction and internal fixation in Vancouver B fractures around CTPS using a broad non-locking plate. Patients treated with osteosynthesis between January 1997 and July 2011 were retrospectively reviewed. All underwent direct reduction and stabilisation using cerclage wires before definitive fixation with a broad DCP. Bicortical screw fixation was obtained in the proximal and distal fragments. We defined failure of treatment as revision for any cause. 101 patients (42 men and 59 women, mean age 79) were included. 70 had minimum follow-up of 6 months. 63 of these went on to clinical and radiological union. Three developed infected non-union. 7 had failure of fixation. Lack of anatomical reduction was the commonest predictor of failure followed by inadequate proximal fragment fixation and infection. 14 patients dropped at least 1 mobility grade from their preoperative status. This is the largest series of a very specific group of periprosthetic fractures treated with osteosynthesis. Patients who develop these fractures are often frail and “high risk” for
In a prospective, randomised trial, we compared the use of three Ullevaal hip screws with that of two Hansson hook-pins in 278 patients with fractures of the femoral neck. Background factors were similar in both groups. Follow-up was for two years. There were no significant differences between the groups in length of time of surgery, hospital stay, general complications, mortality, pain or walking ability. Likewise, the rates of early failure of fixation, nonunion, and the need for reoperation did not differ significantly between the groups. The use of hook-pins was associated with less drill penetrations of the femoral head during surgery (odds ratio 2.6, p= 0.05) and a lower incidence of necrosis of the femoral head (odds ratio 3.5, p = 0.04). There was a strong relationship between poor reduction and fixation of the fracture and subsequent reoperation (p = 0.0005 and p = 0.0001, respectively). Likewise, peroperative drill penetration of the femoral head was associated with a greater risk of reoperation (p = 0.038). Both methods gave favourable results. In total, 22% of the patients needed a
