Total hip arthroplasty following failed internal fixation of hip fractures

A retrospective review was performed on 27 consecutive patients with total hip arthroplasty (THA) following failure of internal fixation of fractures of the proximal femur. The results were comparable to primary THA in femoral neck fractures. Considerably less satisfactory results were obtained in THA in intertrochanteric fractures. Bone loss and medial displacement of the femoral shaft led to high incidence of intraoperative complications and postoperative dislocations. Extreme care must be taken to avoid fracture and penetration of the femoral shaft. Autograft, allograft, or head and neck replacement components should be available for reconstruction of the difficult cases.     

Functional outcome and mortality in nonagenarians following hip fracture surgery

Introduction

The world’s population is ageing and the elderly population itself is growing older. This population shows a high incidence of hip fractures. We performed a retrospective study, reviewing the functional status, postoperative complications and mortality rate of nonagenarians who underwent surgery for hip fracture.

Methods and subjects

56 nonagenarian patients underwent hip fracture surgery in our institution between January 2000 and December 2010. Two of these patients had presented with hip fracture on separate occasions, giving a total of 58 hips for analysis. Patients with open fracture, subtrochanteric fracture, polytrauma and pathological fracture were excluded. The case notes, electronic records and X-rays for all those included in the study were reviewed. The main outcome measures were functional status, postoperative complications and mortality rate at 1 year.

Results

Patients with extracapsular hip fractures were associated with higher risks of postoperative complications (60.7 %; p = 0.037), mortality (25 %; p = 0.003) and more likely to be non-ambulant at 1 year (53.6 vs 16.7 %; p = 0.003). Females were more likely to suffer postoperative complications than males (p = 0.016). 46.6 % of the patients had immediate postoperative complications and most commonly due to urological complications (29.3 %). The 1-year mortality rate was 12.1 %. A notable proportion of patients (65.5 %) remained ambulant 1 year postoperatively, although almost half of the patients (48.3 %) who could ambulate independently pre-injury required a walking aid after hip fracture surgery.

Conclusion

Nonagenarians have good surgical outcomes after hip fracture surgery with low mortality rate. They should be treated similarly as their younger counterparts in terms of decision for surgery. Potential decline in functional status and rehabilitation options should be shared with the patient and family at an early stage.     

Iatrogenic arterial trauma associated with hip joint surgery: an overview

Four cases of iatrogenic arterial injuries following hip surgery are reported. An overview of the literature revealed 122 additional cases. In 93 (74%) of these cases the arterial damage occurred following total hip replacement, 27 (21%) were related to hip fracture correction and six cases complicated other hip surgery procedures. Revisional hip surgery was found to be a definite risk factor. Injuries associated with hip replacement differ significantly in various characteristics of those associated with hip fracture correction. There was a 9% mortality and a 17% permanent disability rate in patients with arterial trauma following total hip replacement. In this group a significantly higher permanent disability rate was noticed in patients who first presented with ischaemia (p less than 0.05). No relationship between the location and mechanism of injury and the outcome was found. Mortality and permanent disability rates of 4% and 11%, respectively, were noticed in patients with injuries related to hip fracture correction.     

Posterior approach for total hip arthroplasty. A study of postoperative course, early results and early complications in 131 cases

We report a consecutive series of 131 total hip arthroplasties using a prosthesis of Brunswik type and a posterior approach to the hip. Special attention is paid to technical details, postoperative course and early complications. The results are compared with those in published studies in which the lateral transtrochanteric approach has been used. Total hip replacement was performed by a team of four persons. This led to a marked decrease in the average operating time (60 minutes). The amount of blood transfused during and after the operation averaged 761 g. The postoperative course was complicated by one wound infection (0.8%). The immediate results regarding pain and walking capacity were good in 83% of the cases. The use of the posterior approach and a highly trained operating team reduced the time required for the operation, the blood loss and the frequency of postoperative complications, and caused less morbidity in the arthritic patients.

The Levine anterior approach for total hip replacement as the treatment for an acute acetabular fracture

The treatment of acetabular fractures in part relies on the selection of a specific surgical approach that allows for accurate reduction of fracture fragments. Moreover, these acetabular approaches were not developed for the insertion of a total hip replacement. Therefore, if a total hip arthroplasty is to be the treatment of an acute acetabular fracture, a single incision that permits reduction of the acetabular fracture fragments and ease of insertion of the arthroplasty components would be desirable. The Levine anterior approach provides both accesses to the anterior wall/column for reduction and fixation and to the femoral shaft for insertion of a total hip replacement. This paper describes that surgical technique and our initial clinical experience with this approach for acute acetabular fractures. A consecutive group of 10 patients with acetabular fractures, all involving the anterior wall/column with articular impaction (>50% of the acetabular roof) including 2 cases with an associated posterior hemitrans-verse component, were reviewed. After fracture reduction and fixation, a hybrid total hip replacement was implanted in all cases with an average acetabular component size of 56 mm (range 52-64). At a mean follow-up of 36 months (range 24-53), all fractures united, and all acetabular components remained fixed with no evidence of migration or loosening. There were 2 complications, a Brooker grade II heterotopic ossification and 1 postoperative anterior dislocation treated successfully with closed reduction and spica cast immobilization. The average Merle d'Aubigné hip score at latest follow-up was 16 (range 13-18). The Levine anterior approach is a reliable, safe, and efficient technique that permits early mobilization of patients with anterior wall/column acetabular fractures requiring a total hip replacement.

Surgical treatment of unstable intertrochanteric fractures by bipolar hip replacement or total hip replacement in elderly osteoporotic patients

A retrospective study was conducted to assess the complications, clinical and functional outcomes at 5 years of follow-up of a series of elderly osteoporotic patients with an unstable intertrochanteric fracture treated by bipolar or total hip replacement. Fifty-four patients with an A2 intertrochanteric osteoporotic fracture were identified between 1996 and 2000. The average age of the patients was 81 years (SD=5). The follow-up time was 5 years. Patients received a bipolar or total hip replacement. During follow-up, we analyzed postoperative complications, mortality rate, functional results using the Harris hip score, time to return to normal activities, and radiographic evidence of healing. One patient died intraoperatively; two patients died on the third and eighth postoperative days and seven patients died within 1 year. Twenty-five patients were living at the 5-year follow-up. Harris hip score at 1 month was 64±8 (mean±SD); at 3 months, 75±5; at 1 year, 76±5; and at 5 years, 76±9. Weight-bearing was permitted immediately after surgery, as tolerated. Time to return to normal daily activities was 27±5 days. No loosening or infection of the implants were observed. In elderly osteoporotic patients with an unstable intertrochanteric fracture, bipolar or total hip replacement in association with reduction of the greater trochanter is a valid alternative to the standard treatment of internal fixation. This surgical technique permits a more rapid recovery with immediate weight-bearing, and a maintenance of a good level of function, with little risk of mechanical failure.     

The outcomes of constrained total hip arthroplasty for recurrent dislocation of hip hemiarthroplasty

IntroductionThe incidence of hemiarthroplasty dislocation for fracture neck of femurs ranges between 1 and 15% and the one-year mortality is 49- 70%. Revision of hemiarthroplasty to total hip replacement using a constrained liner has shown to improve the morbidity and mortality rates. The aim of the study was to assess whether conversion of dislocated hemiarthroplasty to total hip replacement improve functional and one year mortality.MethodsA retrospective analysis of the number of patients who had recurrent dislocations of hemiarthroplasty for fracture neck of femurs were carried out. The data were obtained from NHFD (National Hip Fracture Database) and internal hospital computer systems (Medway, Theatre notes and PACS) between Dec 2008 and Dec 2020. Patient demographics including age, sex, Abbreviated Mental Test Score (AMTS), functional assessment, mortality at one and two years were documented. The risk factors which led to dislocations such as Parkinsons disease, Cerebrovascular accidents, Musculo-neuropathies and Alzheimer`s disease was also noted.ResultsA total of 3994 patients were admitted during the study period of which 1735 (43.4%) patients had hemiarthroplasty. Fifty-six (3.23%) patients had dislocation of hemiarthroplasty. The mean age was 81.4 years (range – 61 to 95). There were 40 (71.4%) females and 16 males (28.6%). The average AMTS score was 5.3. All 56 patients had closed manipulative reduction under anaesthesia within in 12 h of admission. Thirty-one patients (55.4%) went on to have recurrent dislocations of which 18 patients (58.4%) had total hip replacement using captive cup, 6 patients (19.4%) had open reduction,3 patients (9.7%) had excision arthroplasty procedure and four patients (12.5%) had no intervention, Eighteen patients who had total hip replacement with constrained captive for followed up to a minimum of two years (range2- 12 years). There were no intraoperative complications, dislocation or periprosthetic fractures in the follow up period. There was no mortality at the end of two years of follow up in this group, two-year mortality for the patients with alternative management for dislocated hemiarthroplasty was 76.67.ConclusionTreatment of recurrent hemiarthroplasty dislocation by revising to a total hip replacement with a constrained liner gives good functional and mortality outcomes.     

Social function after cervical hip fracture: A comparison of hook-pins and total hip replacement in 47 patients

47 patients with a cervical hip fracture Garden 3 or 4 and fully ambulatory before the fracture, were randomized to either fixation with Hansson hook-pins (24 patients, median age 79 years) or to a Charnley hip replacement (23 patients, median age 80 years). the patients were followed for 2 years. Social function was evaluated using a standard questionnaire.

There were no postoperative deaths and no significant differences in hospital stay. 9/24 patients treated with hook-pins developed healing complications and 2 dislocations occurred in the THR group. After 1 and 2 years, fewer patients treated with hip replacement used outdoor walking aids; they were also more likely to do their own shopping.

Hip replacement is a good choice when treating healthy older people with displaced cervical hip fractures, when primary mortality is expected to be low and the risk of healing complications after nailing is high.     

Increased mortality in patients with a hip fracture-effect of pre-morbid conditions and post-fracture complications

Summary In a cohort of 169,145 patients with a hip fracture and 524,010 controls we observed an excess mortality among patients compared to controls for as long as 20 years after the hip fracture. The main reason for the excess mortality was linked to the trauma that caused the hip fracture. Introduction Patients with a hip fracture have a significant excess mortality. However, it remains unclear if the mortality is linked to the pre-morbid conditions or to complications to the fracture. Methods All subjects with a hip fracture in Denmark between 1977 and 2001 were compared with three age- and gender-matched subjects from the general population. Results A total of 169,145 fracture cases were compared to 524,010 controls. The cases had a much higher prevalence of co-morbidity than the controls. The mortality rate was twice as high in fracture cases compared with controls (HR = 2.26, 95% CI: 2.24–2.27). Adjustments for confounders only changed the excess mortality risk little. The mortality after the hip fracture was divided into two categories: an excess mortality of 19% within the first year following the fracture (relative survival = 0.81 compared to controls), and an excess mortality of 1.8% per year (relative survival 0.982) for every additional year following the fracture. The major causes of the excess mortality were due to complications to the fracture event (70.8% within the first 30 days). Conclusions Patients with a hip fracture have a pronounced excess mortality risk. The major cause was linked to the fracture event and not to pre-existing co-morbidity.     

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.     

Southern hip exposure

The efficacy of the posterior approach to the hip was analyzed in a retrospective study of 168 consecutive procedures performed by the author. Surgical technique is redefined historically and described in detail. Results are studied in two subgroups of hip surgery patients: endoprosthetic replacement (98) and total joint replacement (70). The factors evaluated were surgical time and blood loss, morbidity (dislocation, infection, pain, and limp), mortality, and complications of surgery. The posterior approach to the hip allowed excellent exposure without transecting tissue planes and creating dead spaces. Operative time averaged less than one hour for all cases, and blood loss, less than 500 cc. The four dislocations that occurred postoperatively were in patients with pre-existing flexion contractures. One superficial infection was noted but there was no increase in morbidity due to pain, limp, or loss of motion. Two total joint replacements were complicated by hematoma formation but occurred in patients who had extensive capsule resection and acetabuloplasty. Excellent and rapid exposure with minimal soft tissue destruction or blood loss coupled with few postoperative complications should encourage orthopedic surgeons to include the posterior approach in their treatment of hip problems.

Early complications of hip resurfacing

There has been a rapid increase in the number of hip resurfacing procedures for the treatment of symptomatic osteoarthritis over the last decade. We examine our early complications associated with this procedure. Eight hundred forty consecutive hip resurfacing procedures by 1 surgeon using 1 prosthesis were assessed. The complications seen within the first 12-month postoperative period were analyzed. Specific patient selection criteria were used. Complications such as loosening, femoral neck notching, femoral neck fracture, deep vein thrombosis, stress fracture, nerve palsy, and infection were noted. Complications linked with loosening were categorized to either the femoral or acetabular component. A total of 86 early complications were observed in the 840 resurfacings. Twenty-three (2.7%) required operative intervention, and 10 (1.2%) were converted to stemmed hip arthroplasties. Of these 86 complications, the most common complication was deep vein thrombosis, 19 instances (2.26% occurrence in 840), followed by femoral neck fracture, 11 (1.31%); infection, 10 (1.19%); femoral notching, 10 (1.19%); transient nerve palsy, 8 (0.95%); acetabular loosening, 6 (0.71%); hematoma, 5 (0.60%); and stress fracture, 4 (0.48%). The fractures occurred mostly in patients older than 60 years.     

Characteristics of male hip fracture patients

BACKGROUND AND AIMS: Among men, hip fracture is the most common outcome of osteoporosis. The aim of this study was to investigate the clinical characteristics, treatment, complications, short-term outcome and mortality of male hip fracture patients. MATERIAL AND METHODS: Operation theatre logs of all hip fracture patients operated on (1124 patients) at Kuopio University Hospital in 1989-1993 were reviewed. Medical records of the 276 male patients who underwent surgery (25 % of all patients) were studied. RESULTS AND CONCLUSIONS: 233 hip fractures (86 %) in men were due to low energy trauma. Of these cases, 61 % of the fractures occurred at the femoral neck, 31 % were pertrochanteric and 8 % subtrochanteric. The vast majority (90 %) of these patients had some chronic medical condition, and in 66 % the condition influenced motory or sensory functions. Hemiarthroplasty was most often used for femoral neck fractures (64 %). Internal fixation was used for pertrochanteric (97 %) and subtrochanteric (94 %) fractures. 20 % of the men had post-operative complications during the 1.5 year follow-up. During primary hospitalisation mortality was 3 %. Within 1.5 years of the fracture 40 % of the men had died, resulting in a mortality three times higher than age matched Finnish male population.
