Periprosthetic fractures after total hip arthroplasty are challenging, with potential difficulties associated not only with the fracture but also with implant loosening and bone loss. The incidence of periprosthetic fractures is gradually increasing. We undertook this study to evaluate the periprosthetic fractures presenting to our unit in terms of mechanism of failure, classification and treatment. Charts of patients with periprosthetic fractures presenting within the past six years were retrospectively analysed for demographic and injury details and corresponding radiographs were reviewed to classify the fracture and follow treatment. 45 fractures were identified, with an average age of 78.3 years. The male to female ratio was 5:4. Only 4 fractures occurred in revision prostheses. Two fractures were intraoperative. The Vancouver system was used to classify the fractures, which can also form a basis for treatment. Three fractures of Vancouver type A were managed conservatively without complication. Thirteen fractures were Vancouver type B1, 12 of which underwent internal fixation, mostly plate osteosynthesis; two of these subsequently failed. Recent fractures have been stabilised using locking plates, with no recorded failures. Fifteen fractures were Vancouver type B2, 11 of which were greater than 5 years post arthroplasty. Most underwent revision of the femoral component. Five of these patients had reported pain for some time preceding fracture. Seven fractures were Vancouver type B3, all occurring greater than 7 years post arthroplasty. Most underwent femoral revision. Seven fractures were Vancouver type C, all underwent plate fixation without failure. Although there is variability within the group studied, this series demonstrates gradual standardisation of treatment with use of locking plates and a preferred long revision femoral stem. The reports of pain preceding fracture in a proportion of the Vancouver B2 group prompts greater postoperative surveillance in patients with early signs of femoral loosening.
We assessed the outcome of patients with Vancouver type B2 and B3 periprosthetic fractures treated with femoral revision using an uncemented extensively porous-coated implant. A retrospective clinical and radiographic assessment of 22 patients with a mean follow-up of 33.7 months was performed. The mean time from the index procedure to fracture was 10.8 years. There were 17 patients with a satisfactory result. Complications in four patients included subsidence in two, deep sepsis in one, and delayed union in one. Concomitant acetabular revision was required in 19 patients. Uncemented extensively porous-coated femoral stems incorporate distally allowing stable fixation. We found good early survival rates and a low incidence of nonunion using this implant.
In Ireland and the United Kingdom, there were 22 deaths as a direct result of blood transfusion during the period October 1996 to September 1998. Added to this there were 366 complications directly related to blood transfusion. With the introduction of a Haemovigilance Nurse and changing surgical personnel we were anxious to review transfusion rates in our Regional Orthopaedic Centre for the period January 1999 to July 2000. All patients undergoing primary or revision arthroplasty in our Regional Orthopaedic Unit during the study period were reviewed. 459 primary or revision arthroplasties were performed in the study period. Prior to the introduction of a Haemovigilance Nurse, transfusion rates for primary arthroplasties averaged 1. 41 units/patient, with 74% of patients being transfused. After the introduction, transfusion rates averaged 0. 51 units/patient, with 31% of patients being transfused. Prior to the introduction of a Haemovigilance Nurse revision arthroplasties averaged 2. 5 units/patient, with 100% of patients being transfused. After the introduction transfusion rates averaged 1. 2 units/patient, with 62% of patients being transfused. There was a statistically significant difference between transfusion rates prior to and post the introduction of a Haemovigilance Nurse (p<
0. 005). In the current climate post the Finlay Tribunal in Ire-land and the resultant increased public awareness, transfusing a patient without justifiable cause is no longer acceptable. Patients in this Unit are now transfused according to clinical needs and accurate measurement of intra-operative and post-operative blood loss, compared to their calculated maximum allowed blood loss (MABL). Our new transfusion protocol is working well without compromising patient care.
In Ireland and the United Kingdom, there were 22 deaths as a direct result of blood transfusion during the period October 1996 to September 1998. Added to this mortality, there were 366 cases of complications directly related to blood transfusion. With the introduction of a Haemovigilance Nurse, changing surgical personnel and an increased public awareness of the potential hazards of transfusion, we were anxious to review whether transfusion rates have changed in our Regional Orthopaedic Centre for the period January 1999 to July 2000 All patients undergoing primary or revision arthroplasty in our Regional Orthopaedic Unit during the study period were retrospectively reviewed. 459 primary or revision arthroplasties were performed in the study period. Prior to the introduction of a haemovigilance Nurse, from the period January 1999 to October 1999, transfusion rates for primary arthroplasties averaged 1.41 units/patient with 74% of patients being transfused. After the introduction of a haemovigilance Nurse, from November 1999 to July 2000, transfusion rates for primary arthroplasties averaged 0.51 units/patient, with 31% of patients being transfused. Prior to the introduction of a haemovigilance Nurse revision arthroplasties averaged 2.5 units/patient, with 100% of patients being transfused. After the introduction of the haemovigilance Nurse transfusion averaged 1.2 units/patient, with 62% of patients being transfused. There was a statistically significant difference between transfusion rates prior to the introduction of a Haemovigilance Nurse and new surgical personnel and the period after their introduction (p<
0.005). In the current climate post the Finlay Tribunal and the resultant increased public awareness, transfusing a patient without justifiable cause is no longer acceptable. Patients in this unit are now transfused according to clinical needs and accurate measurement of intra-operative and post-operative blood loss, compared to their calculated maximum allowed blood loss (MABL). The changing transfusion rates seen in our Unit correspond to the introduction of a Haemovigilance Nurse and a change in surgical personnel. Our new transfusion protocol is working well without compromising patient care.
