Acute total hip arthroplasty for acetabular fractures in the elderly: 11 patients followed for 2 years

We describe the use of cable fixation and acute total hip replacement for acetabular fracture in the elderly. 12 patients with acetabular fractures, having a mean age of 79 (65-93) years, were treated with cable fixation and acute total hip arthroplasty. 8 were T-shaped fractures and 4 associated fractures of the posterior column and posterior wall. 1 patient died 5 months after surgery and the remaining 11 were followed for 2 years. All patients had a good clinical outcome. Radiographic assessment showed healing of the fracture and a satisfactory alignment of the cup without loosening. This surgical technique provides good primary fixation, stabilizes complex acetabular fractures in elderly patients with osteoporotic bone and permits early postoperative mobilization.     

Cable fixation and early total hip arthroplasty in the treatment of acetabular fractures in elderly patients

Eighteen patients with acetabular fractures, with a mean age of 76 years, were treated with cable fixation and acute total hip arthroplasty. Nine were T-shaped fractures, 4 associated transverse and posterior wall, 2 transverse, 2 posterior column and posterior wall, and 1 anterior and posterior hemitransverse fractures. One patient experienced 3 episodes of hip dislocation within 10 months after surgery. All the others had a good outcome at a mean follow-up time of 36 months. Radiographic assessment showed healing of the fracture and a satisfactory alignment of the cup without loosening. This option provides good primary fixation, stabilizes complex acetabular fractures in elderly patients, and permits early postoperative mobilization.     

Die Behandlung von Acetabulumfrakturen bei geriatrischen Patienten mittels modifizierter Kabelcerclage und primärer Hüfttotalprothese

This prospective study addresses early results of the treatment of acute acetabular fractures in elderly patients by total hip arthroplasty and cerclage wiring.Fifteen patients with an average age of 81 years were treated at our institution between February 1998 and December 2000. There were two transverse fractures, eight T-shaped fractures, two transverse fractures with associated posterior wall fracture, two posterior column fractures with associated posterior wall fracture, and one fracture of both columns. Treatment consisted of cerclage wiring of the fracture and primary non-cemented total hip replacement.All of the patients were followed for a mean of 36 months. Although there was one patient with three hip dislocations during the first 10 months after the operation, we found an excellent or good result for the entire group. During this relatively short follow-up period, we have not found a radiological loss of fracture reduction of more than 1 mm or a cup migration of more than 3.2 mm. All of the fractures healed and no loosening of the implant was evident.Primary total hip arthroplasty combined with internal fixation is a valid treatment option for acetabular fractures in the elderly. Preliminary results are convincing, but a bigger patient population and a longer follow-up time are necessary before we are able to draw final conclusions.

Management of Acetabular Fractures in the Elderly Patient

Operative management of displaced acetabular fractures yields better results than nonoperative management. Over the past decade, surgical approaches to the acetabulum and the surgical tactic for repair of common fracture patterns have been advanced. Excellent outcomes after repair of these injuries can be achieved. In some cases, as in the elderly, or in those cases in which there is significant destruction of the articular cartilage, primary total hip arthroplasty may provide the best solution. Removal of the femoral head allows for excellent exposure of the acetabulum, making it possible to stabilize most fractures without the need for extensile or intrapelvic approaches. The surgical technique that has been successfully used calls for gaining primary stability of the acetabular columns by open reduction and internal fixation and then using the acetabular component to replace the articular surface. The columns need not be anatomically reduced. Multiholed acetabular shells can be used as internal fixation devices by placing screws into the columns enhancing the stability of the repair. In older individuals with severe osteoporosis, a typical fracture pattern results in intrapelvic dislocation of the femoral head with a blowout fracture of the anterior column and medial wall. Reinforcement rings with cemented acetabular fixation can be used in these cases. The femoral head can be used as bulk bone graft to replace and reinforce the reconstruction. Techniques common to revision of failed acetabular components are helpful in this setting. The results of reconstruction of severe acetabular fractures with total hip replacement have been reported to be similar to those achieved for reconstruction of osteoarthritis.

Stabilization of an acetabular fracture with cables for acute total hip arthroplasty

A critical stage of total hip arthroplasty for an acute acetabular fracture where extensive comminution, impaction, and osteopenia thwart the application of conventional open or closed methods, especially in the elderly, is stable fixation of the acetabulum. The use of 2-mm braided cables permits effective immobilization of the fracture for use in conjunction with a hybrid arthroplasty. The method is consistent with the use of a conventional arthroplastic incision and is suitable for other applications including the fixation of periprosthetic fractures, bulk allografts, and conventional acetabular fractures.

Total hip replacement for acetabular fractures. Results in 121 patients operated between 1983 and 2003

Total hip replacement has an important role in the treatment of acetabular fractures. Immediate total hip arthroplasty is only indicated for some rare cases but late reconstruction is performed more frequently and may follow failed non-operative or operative treatment of the original acetabular fracture. INTRODUCTION: The purpose of this study is to determine the results of the use of total hip replacement for the treatment of acetabular fractures and to compare the results of the early and late reconstruction group. MATERIALS AND METHODS: 121 acetabular fractures treated with total hip arthroplasty between 1983 and 2003 at the University Hospitals Gasthuisberg in Leuven, Belgium were retrospectively studied. The patients were divided into two groups. In the "early reconstruction group" total hip arthroplasty was performed as primary treatment of the acetabular fracture. In the "late reconstruction group": total hip arthroplasty was performed following failed operative or non-operative treatment of the acetabular fracture. The indications for total hip arthroplasty and the surgical technique in both the early and late reconstruction group were compared. Secondly, complications were reviewed in both groups and a functional scoring system was applied for each patient. RESULTS: Primarily there was a significant difference in the age of the patient population of each group with a predominance for older patients in the early reconstruction group. Secondly, less revisions were performed in the early reconstruction group: 8% compared to 22% in the late reconstruction group. DISCUSSION: The results obtained in our patient groups were compared to the results found in literature by a Medline search. In general, our results were comparable to the results found in literature but a remarkable difference was found between different authors. CONCLUSION: Total hip replacement for acetabular fractures is rarely indicated in the acute phase. After failed treatment of an acetabular fracture, total hip replacement has to be considered as a salvage procedure. In both cases, one may not forget total hip arthroplasty is a severe intervention associated with a high number of complications.     

Traumatic anterior dislocation of the hip joint with posterior acetabular wall fracture

The incidence of traumatic hip dislocation has increased in recent years as a result of high-energy trauma. Anterior hip dislocation forms less than 10-15% of all traumatic hip dislocations. Only a few case reports describe anterior dislocation along with acetabular fractures. The acetabular fracture involved the anterior wall or column in all such cases. We describe a rare case in which anterior superior dislocation of the hip was associated with a large fracture fragment of theposterior acetabular rim and adjacent wall.

Survivorship of the native hip joint after percutaneous repair of acetabular fractures in the elderly

Our purpose was to examine survivorship of the native hip joint in patients ages 60 and over who underwent percutaneous reduction and fixation of acetabular fractures. A retrospective review at a University Level I Trauma Center was performed. Our institutional trauma database was reviewed. Patients aged 60 or older treated with percutaneous reduction and fixation of acetabular fractures between 1994 and 2007 were selected. 79 consecutive patients with 80 fractures were identified. Rate of conversion to total hip arthroplasty were used to construct a Kaplan–Meier curve showing survivorship of the native hip joint after treatment. 75 fractures had adequate clinical follow-up with a mean of 3.9 years (range 0.5–11.9 years). Average blood loss was 69 cc and there were no postoperative infections. 19/75 (25%) were converted to total hip arthroplasty at a mean time of 1.4 years after the index procedure. Survivorship analysis demonstrated a cumulative survival of 65% at 11.9 years of follow-up. There were no conversions to arthroplasty beyond 4.7 years postoperatively. There were no statistically significant associations between conversion to arthroplasty and age, sex, closed vs. limited open reduction, and simple vs. complex fracture pattern. Percutaneous fixation is a viable treatment option for patients age 60 or greater with acetabular fractures. Rates of conversion to total hip arthroplasty are comparable to open treatment methods and if conversion is required, soft tissues are preserved for future surgery.
