Valgus-impacted subcapital neck of femur fractures: a systematic review, meta-analysis with cost analysis of fixation in-situ versus nonoperative management. Hip Int 2024; 34:260-269. [PMID: 38116748 PMCID: PMC10935617 DOI: 10.1177/11207000231210240] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/24/2022] [Accepted: 04/01/2023] [Indexed: 12/21/2023]
Abstract
BACKGROUND The management of the valgus-impacted neck of femur fracture (AO/OTA 31-B1) remains contentious. The objective of this study was to determine whether operative intervention is cost-effective. METHODS We conducted a systematic review using electronic databases (Medline, Embase, Cochrane, Ebsco, Scholar) identifying studies published in the English language concerning valgus-impacted neck of femur fractures until June 2022. Additional studies were identified through hand searches of major orthopaedic journals, and bibliographies of major orthopaedic textbooks. MeSH terms (hip fracture and femoral neck fracture) and keywords (undisplaced, valgus-impacted, valgus, subcapital, Garden) connected by the Boolean operators "AND" and "OR" were used to identify studies. 2 reviewers independently extracted the data using standardised forms and recording spreadsheet. Methodological validity prior to inclusion in the review using standardized critical appraisal instruments from the Joanna Briggs Institute Meta-analysis of Statistics Assessment and Review Instrument. Meta-analysis was undertaken. Outcome measures were rate of displacement, avascular necrosis, non-union, mortality and requirement of further operative intervention. A cost utility analysis was then conducted to compare the 2 groups on the basis of the cost of initial treatment and the potential requirement of secondary intervention to hemiarthroplasty. RESULTS 47 studies met the inclusion criteria. Meta-analysis data demonstrated a significant difference in the displacement rate of 22.8% and 2.8% between the nonoperative and internal fixation groups respectively (p = 0.05). The overall incidence of further operative intervention for each group was 23% and 10% respectively. There was no significant difference with respect to avascular necrosis, mortality or union rates. The cost utility analysis revealed nonoperative management to be approximately 60% more costly than initial internal fixation when the costs of subsequent surgery were included. CONCLUSIONS This meta-analysis of the existing literature concludes that whilst nonoperative management is possible for valgus impacted neck of femur fractures, it is associated with higher complication rates and greater expense than management by internal fixation.

Abstract
OBJECTIVES Hemiarthroplasty is recommended for treatment of displaced femoral neck fractures in physically compromised elderly patients. The objective of this study was to analyze survival of patients aged >80 years after the implantation of either an Austin-Moore type prosthesis or a bipolar bearing prosthesis. METHODS An Austin-Moore or bipolar hemiarthroplasty was implanted into 120 patients aged >80 years. Demographic data were collected. Survival rate at 5 years and factors related to mortality were analyzed. RESULTS Sixty-two patients received Austin-Moore hemiarthroplasty, and 58 received bipolar hemiarthroplasty. No significant differences in gender, comorbid conditions, ASA scores, duration of hospitalization, intraoperative blood loss, duration from injury to operation, or postoperative morbidity between the two groups were found. However, patients who received the Austin-Moore hemiarthroplasty were older and had shorter operation time than those who received bipolar hemiarthroplasty. Kaplan-Meier estimates of 5 years survival were 40.0% for patients who received Austin-Moore hemiarthroplasty, and 62.9% for patients who received bipolar hemiarthroplasty. Cox proportional hazard regression analysis of risks factors of death revealed that patients who underwent Austin-Moore hemiarthroplasty were 2.0-fold more likely to die when compared to those who received bipolar hemiarthroplasty. CONCLUSIONS Elderly patients who receive bipolar hemiarthroplasty may have a more favorable survival outcome when compared to those who receive unipolar hemiarthroplasty.

Abstract
OBJECTIVES We compared the interrater reliability of five classification systems and surgeons' global impressions of the quality of femoral neck fracture reduction. METHODS Six orthopedic trauma surgeons, six orthopedic nontrauma surgeons, and six orthopedic residents from three sites each rated 50 radiographs of postoperative femoral neck fractures fixated with cannulated screws or a sliding hip screw, using their overall impression, the Garden Index, Lowell's criteria, Lindquist and Tornkvist's criteria, the Western Infirmary Glasgow (WIG) angle, and standards established by a working group of orthopedic trauma surgeons. RESULTS Reliability estimates for the Garden Index, Lowell's criteria, and the working group standards all fell within the range of moderate agreement [intraclass correlation coefficient (ICC) range 0.41-0.48], with no instrument achieving higher reliability than reviewers' overall impressions (ICC 0.49, 95% CI 0.39-0.61). Reviewers reached only fair agreement using Lindquist and Tornkvist's criteria and the WIG angle (kappa = 0.27 and 0.39, respectively). Trauma surgeons consistently achieved higher agreement than did nontrauma surgeons and trainees. CONCLUSIONS Future studies using quality of reduction as an outcome measure or exploring the prognostic importance of reduction quality should measure this with trauma surgeons' overall impression, rather than with less experienced assessors or using one of the alternative instruments.

Abstract
224 patients with undisplaced femoral neck fractures treated with two parallel Hansson hook pins were studied. After a mean follow-up time of 32 months (S.D. 5.2), 15% had a reoperation. 11% were considered failures, mostly avascular necrosis, and 9% had a secondary arthroplasty. Possible risk factors for poor outcome were analysed. Neither high age nor surgical delay was associated with increased failure rate. Survivors received a questionnaire, and 40% stated that they had mild or severe pain in the hip when walking, 25% had pain at rest and 25 stated that they thought "always" or "often" about their injury. The younger the patient, the more frequent the report of subjective pain. 51% of individuals under 80 years reported pain when walking, compared to 27% aged 80 or older (p=0.016). Corresponding numbers for pain at rest were 32 and 12% (p=0.034). The failure rate did not differ between the age groups, but the younger patients had more reoperations (p=0.046) and thought more frequently about their injury (p=0.016). An undisplaced femoral neck fracture is a major injury with a long-term daily discomfort in about 25% and clinical failure in 11%.

Abstract
A review of recent advances in the treatment of intracapsular hip fractures in the elderly patient is offered to provide some guidelines on choosing the appropriate treatment for a given patient. Alternatives discussed include open reduction and internal fixation versus arthroplasty; unipolar versus bipolar hemiarthroplasty versus total hip arthroplasty; cemented versus cementlless prostheses; and a surgical approach. These recommendations are based upon a review of the substantial literature on the subject and the author's own experience. It is recommended that patients more than 60-years-old with a femoral neck fracture be treated in the following manner: Patients with undisplaced, stable fractures perform an ORIF, patients with displaced fractures, replace the head of the femur, the use of a Moore or Thompson prostheses should be relegated to the medically infirm, minimally ambulatory patient, modular unipolar or bipolar (cemented stem) hemiarthroplasty has the most reliable and predictable outcome in most patients, an uncemented modular hemiarthroplasty should be considered in patients with significant cardiovascular risk factors, THA perhaps recommended for the "active elderly patient". The use of large heads and meticulous capsular repair techniques will reduce the early dislocation rate while still allowing excellent long-term functional outcomes.

Abstract
BACKGROUND The optimal treatment for femoral neck fracture is a matter of controversy. We compared the outcome of displaced fractures with good healing potential (moderately displaced fractures) to the outcome of undisplaced fractures treated by internal fixation with 2 parallel screws. METHODS In a consecutive series of hip fracture patients, the rates of reoperation and mortality for 225 undisplaced fractures were compared to those for 241 moderately displaced fractures. The patients were followed for 1-6 years. RESULTS The total rate of reoperation was 19% (9% because of healing complications) for the undisplaced fractures and 33% (20% because of healing complications) for the moderately displaced fractures. Fracture displacement was the main predictor of reoperation. There was no difference in mortality between the groups, and patient-related background parameters (rather than fracture displacement) were the main predictors of mortality. INTERPRETATION Undisplaced fractures should be treated by internal fixation. The best treatment for moderately displaced fractures remains to be determined.

Abstract
BACKGROUND Studies have shown that the degree of initial displacement and also comminution of the femoral calcar, size of the head and varus angulation are prognostic of failure in displaced femoral neck fracture. We have applied these radiographic criteria in order to select patients who would benefit from internal fixation as opposed to primary hemiarthroplasty, and this prospective study was conducted in order to monitor the results of this strategy. METHODS 683 displaced fractures of the femoral neck were treated with internal fixation or primary hemiarthroplasty based on the proposed radiographic criteria in a prospective consecutive study, and the patients were followed for 1-6 years. We treated 228 fractures with internal fixation and 455 by bipolar hemiprosthesis. The choice of operation was based on clinical evaluation of the patient and assessment of the assumed healing potential of the fracture, as determined by radiographic evaluation. Revision and mortality were primary endpoints. RESULTS 54 (24%) of the patients originally treated by osteosynthesis were revised, whereas 9 (2%) of the patients treated with hemiarthroplasty had revision surgery. There were no significant differences in mortality between the groups at 30, 120 or 365 days. INTERPRETATION Even when treating only the fractures with the assumed best healing potential with internal fixation, the results are inferior to hemiarthroplasty.

Abstract
The incidence of femoral neck fracture among the elderly in the United States is expected to increase dramatically because of the anticipated explosion in the population aged 65 years and older, increased life expectancy, and the rising incidence of osteoporosis. The resulting public health implications may be significant, with annual hospital admissions resulting from hip fracture projected to increase to 700,000 by 2050, and with annual spending on hip fracture care expected to exceed 15 billion dollars within a few years. The decision to perform internal fixation, unipolar hemiarthroplasty, bipolar hemiarthroplasty, or THA must be based on patient mental status, living arrangement, level of independence and activity, and bone and joint quality.

Abstract
This study assessed the effect of fracture displacement and elapsed time before surgery on the development of avascular necrosis and nonunion after internal fixation of femoral neck fractures. Twenty-eight patients with 30 femoral neck fractures who underwent internal fixation and completed a minimum of 2 years' follow-up were retrospectively analyzed. The rates of avascular necrosis and nonunion were 12.5% and 25%, respectively, among patients who underwent surgery before 12 hours had elapsed and 14% and 27% among those who underwent surgery after that time. The rates of avascular necrosis and nonunion associated with fracture displacement were 6% and 18%, respectively, among patients with undisplaced (Garden stages 1 and 2) fractures and 23% and 38% among those with displaced (Garden stages 3 and 4) fractures. Nonunion and avascular necrosis led to the necessity for additional surgery in 11 of 30 (36%) hips. Internal fixation of femoral neck fractures is associated with a high initial complication rate, but if successful, the procedure ensures an excellent long-term outcome. Internal fixation should be considered the treatment of choice in young patients with nondisplaced fractures.

Abstract
In almost all the patients over 65 years of age with intracapsular femoral neck fractures who we treated over a 2-year period, we used osteosynthesis with Ace 6.5-mm cannulated cancellous screws. We then followed them for at least 24 months. Each of the seven nondisplaced fractures healed. Of the 20 displaced fractures, 14 were rated as healed, 5 as failures, and 1 as a late segmental collapse. Among the 14 displaced fractures with an operative delay of 1 day, 12 healed, whereas only 2 of the 6 fractures with an operative delay of 2 days or more did so. Of the 12 typical fractures (with a medial spike in the head fragment), 10 healed, as did 4 of the 8 crescent or mixed-type fractures. The treatment of choice for nondisplaced fractures is osteosynthesis. Displaced fractures that occur on the day of operation or the day before should be treated with osteosynthesis if they are the typical type. The rest of the displaced fractures should be considered candidates for primary prosthetic replacement.

Abstract
Seventy patients with nondisplaced femoral neck fractures treated by cannulated screw fixation were followed up prospectively for 6 months. Preinjury Functional Independence Measure scores and comorbidities were recorded as were operative time, type of anesthesia, estimated blood loss, transfusions, and postoperative complications. Functional Independence Measure scores were reassessed at 3 and 6 months. The mean age of the patients was 78 years. The 6-month mortality was 5.7%. The mean overall Functional Independence Measure scores at 3 and 6 months were 86% and 89% of the initial score respectively. Locomotion Functional Independence Measure scores at 3 and 6 months were 73% and 89% of the initial score, respectively. Multiple regression analysis found patient age and initial overall Functional Independence Measure score to be independent predictors of overall, locomotion, and transfer Functional Independence Measure scores at 3 months. At 6 months, only initial Functional Independence Measure score predicted ultimate Functional Independence Measure scores. This suggests that patient age may affect the speed of recovery but not the ultimate functional result. Of comorbidities, only chronic obstructive pulmonary disease significantly affected functional recovery at 3 months, but not at 6 months. Operative time, estimated blood loss, type of anesthesia, and patient gender did not affect functional outcomes. Patients who sustain a nondisplaced femoral neck fracture experience predictable and lasting loss of function. Low initial functional status predicts a poorer outcome. Age and pulmonary comorbidity affect speed of recovery.

Abstract
Femoral neck fractures in the geriatric patient continue to represent a therapeutic challenge. Despite advances in surgical techniques and medical care, the risk of nonunion and osteonecrosis after fixation have not changed appreciably in the last 50 years. Considerable debate continues to occur with respect to the relative merits of internal fixation versus arthroplasty. The relative benefits and complications of unipolar and bipolar hemiarthroplasty, as well as total hip replacement, continue to be poorly understood. The next decade will bring advances in the prevention and treatment of osteoporosis that may finally decrease the incidence of these fractures. Advances in the use of bone graft substitutes may finally improve the outcome of internal fixation.

Abstract
Forty six patients who underwent conversion of their Austin Moore hemiarthroplasty to a total hip replacement were assessed clinically and radiologically. Forty patients requiring conversion had either groin or thigh pain. Operative findings showed acetabular cartilage degeneration and femoral loosening as the main pathological process causing their symptoms. Total hip replacement gave complete resolution of the symptoms in 41 patients. We propose early conversion to total joint arthroplasty in patients with painful hemiarthroplasties.

Abstract
We examined both impairment and disability of 58 patients who were referred to our rehabilitation center after surgery of hip fracture. The mean age was 86.7 years. The impairment was measured by the Motricity Index (MI) scale and disability by means of the Functional Independence Measure (FIM) scale. At admission, the MI median value was 64 and at discharge the value was 84 (range of scale, 0-100). The FIM median value was 57.5 at admission and 82 at discharge (range of scale, 18-126). Our data indicate that, on average, patients recover, even at very advanced age, but still require supervision at discharge. Twelve patients died after complications of previous risk factors. When general conditions were satisfactory, no complications arose.

Abstract
After internal fixation of a femoral neck fracture, 3 months is the critical time for planning rehabilitation of the patient. Most failures in the elderly occur within this time. In a series of 165 patients, we followed 127 women and 38 men with a median age of 81 (63-97) years from an examination at 3 months to reoperation or survival of the hip. 36 patients had radiographic signs of disturbed healing at the 3-month follow-up--change in fracture position by 10 mm, change in screw position by 5%, backing of the screws by 20 mm, or perforation of the femoral head by the screw. These signs had a high association with local complications and need for a later reoperation. High age and male sex increased this association. Signs of impaired healing made nonunion likely, but did not predict late segmental collapse of the femoral head. Patients with signs of disturbed healing and those closest to them should be informed about the value of early check-ups in case of pain and impaired function.

Abstract
An algorithm was designed for preoperative prediction of the risk for reoperation, and the mortality risk, after internal fixation of femoral neck fractures. Out of 51 reviewed studies of femoral neck fractures, eight met specified inclusion criteria such as low dropout rates, a minimum of ten surgeons performing the surgery, a minimum of 2 years follow-up, and a standard age, sex, and Garden class distribution. Five of these studies were used for the construction of the algorithm, and the remaining three for testing the specificity and sensitivity of the algorithm. A separate analysis of the influence of age on the reoperation rate was also performed. In the analysis of 399 reviewed cases of femoral neck fractures, the specificity for the algorithm in predicting the risk for reoperation was 96%, and the sensitivity was 51%. The positive predictive value for the algorithm in predicting the risk for reoperation was 77%, which was three times higher compared to the commonly used predictors age and Garden class (positive predictive value 25%). For prediction of the mortality risk the positive predictive value for-the algorithm was 57%.

Abstract
OBJECTIVE This report introduces a new type of pin for treatment of femoral neck fractures. DESIGN Retrospective analysis. METHODS The pin used in this study has a tapered thread in its middle portion to facilitate fixation in the lateral femoral cortex, as well as a simple tip that allows percutaneous pinning without displacement of the reduced position. Between 1978 and 1993, we used our pins on 218 hips in 214 patients, all age sixty years or more. We were able to observe postoperative osteosynthesis in 176 hips (172 patients) during a mean follow-up period of thirty-two months; the incidence of osteosynthesis and local postoperative complications was also charted. RESULTS Osteosynthesis was obtained in 153 hips (87 percent); for groups based on Garden's classification, results were as follows: twenty-four of twenty-four hips in type 1, fifteen of sixteen in type 2, sixty-three of seventy-one in type 3, and fifty-one of sixty-five in type 4. Some local postoperative complications were observed, including second fractures at the pin insertion point (three hips), pin penetration of the femoral head (twenty-four hips), and pin slippage (three hips). CONCLUSION This pin is effective in the treatment of femoral neck fractures and has the added benefits of being minimally invasive and low in cost.

Abstract
The influence of three different fixation devices on late healing complications after femoral neck fractures was studied in a large patient group from three different hospitals. Except for the choice of device, which was unique to each hospital, all other factors having a potential influence on the late outcome, such as sex and age of the patients, initial degree of fracture dislocation and quality of surgical reduction were similar among the three groups. Within a 2-year observation period the incidence of late segmental collapses (14%-19%) was not related to choice of device, but a higher number of non-unions (27%-30%) occurred after adaptive non-rigid methods using screws (von Bahr) or a flanged nail (Rydell) than after a more rigid osteosynthesis (8%, Deyerle). Using such a rigid fixation, the complication rate could be reduced by one-third and the need for revision surgery halved. A device providing stable fixation should be preferred for treatment of femoral neck fractures in the elderly to prevent the healing complications related to insufficient stabilization.

Abstract
The results of stabilization of an intracapsular fracture of the femoral neck with cannulated screws placed in parallel in 141 patients between 1980 and 1985 were reviewed retrospectively. Fifty patients (35 per cent) had a non-displaced fracture (Garden Stage I or II) and ninety-one (65 per cent) had a displaced fracture (Garden Stage III or IV). The median age of the patients was sixty-eight years (range, twenty-four to ninety-five years). The mean duration of follow-up was eight years. No patient died or had a wound infection during the stay in the hospital. Twenty-nine patients, who had a median age of seventy-five years (range, fifty-six to ninety-five years), died within sixty months after treatment; eleven of them (median age, seventy-five years [range, sixty-five to eighty-six years]) died within the first twelve months. There was a loss of position or a non-union of the fracture in five patients (4 per cent) and healing of the fracture in 136 patients (96 per cent). Thirteen patients (11 +/- 3 per cent) had histological or roentgenographic evidence of osteonecrosis within twenty-four months after treatment. Ten of these patients had had a displaced fracture. Osteonecrosis developed in thirteen additional patients during the remaining period of follow-up. Eight of these patients had had a displaced fracture. The prevalence of osteonecrosis at the time of the most recent follow-up (mean duration, eight years) was 22 +/- 4 per cent. Osteonecrosis developed in eight of the forty-one patients who had had a Garden Stage-II fracture, in six of the thirty patients who had had a Garden Stage-III fracture, and in twelve of the forty patients who had had a Garden Stage-IV fracture. The fifty-five surviving patients in whom the fracture healed without complications were found to be functioning well more than sixty months after the fracture.

Abstract
Four to 12 years after primary treatment of femoral neck fracture with hemiarthroplasty in a group of Finnish patients and secondary total hip arthroplasty as a salvage procedure for healing complication after primary osteosynthesis in a group of Swedish patients, function was classified and the Nottingham Health Profile questionnaire was applied. The two groups were comparable with regard to age, sex, and social status. The patients with secondary total hip arthroplasty used walking aids to a lesser extent than the patients with hemiarthroplasty and experienced less problems in several aspects of life. Walking ability was considered unchanged, compared to prefracture, to a larger extent in the secondary total hip arthroplasty group. Thus, secondary total hip arthroplasty in patients with healing complication following primary osteosynthesis gives better long-term functional capacity than that obtained with a primary hemiarthroplasty.

Abstract
Methods of meta-analysis, a technique for the combination of data from multiple sources, were applied to analyze 106 reports of the treatment of displaced fractures of the femoral neck. Two years or less after primary internal fixation of a displaced fracture of the femoral neck, a non-union had developed in 33 per cent of the patients and avascular necrosis, in 16 per cent. The rate of performance of a second operation within two years ranged from 20 to 36 per cent after internal fixation and from 6 to 18 per cent after hemiarthroplasty (relative risk, 2.6; 95 per cent confidence interval, 1.4 to 4.6). Conversion to an arthroplasty was the most common reoperation after internal fixation and accounted for about two-thirds of these procedures. The remaining one-third of the reoperations were for removal of the implant or revision of the internal fixation. For the patients who had had a hemiarthroplasty, the most common reoperations were conversion to a total hip replacement, removal or revision of the prosthesis, and débridement of the wound. Although we observed an increase in the rate of mortality at thirty days after primary hemiarthroplasty compared with that after primary internal fixation, the difference was not significant (p = 0.22) and did not persist beyond three months. The absolute difference in perioperative mortality between the two groups was small. An anterior operative approach for arthroplasty consistently was associated with a lower rate of mortality at two months than was a posterior approach. Some reports showed promising results after total hip replacement for displaced fractures of the femoral neck; however, randomized clinical trials are still needed to establish the value of this treatment.

Abstract
We examined the physical and social function of patients surviving 10 years after internal fixation of a hip fracture. 74 out of 362 patients were alive 10 years after their fracture. In 47 survivors after cervical fracture, secondary hip arthroplasties had been performed in 25, and nails had been extracted in 13. The implants had been removed in 8 of 27 with trochanteric fracture. 58 survivors were interviewed; three fourths were still living in their own homes, with more than half needing no home assistance. However, limitation of activities, caused by the fracture, was experienced by more than one third of the survivors.

Abstract
We have previously studied the radiographic outcome of femoral neck fracture osteosynthesis with either two hook-pins or a four-flanged nail performed by a small group of surgeons with special interest in the methods. In 138 femoral neck fractures a backwards stepwise logistic regression analysis was used to study the significance of preoperative fracture-related factors, intraoperative factors and the osteosynthesis. The development of non-union/redisplacement and segmental collapse of the femoral head was influenced by fracture displacement (P 0.001) and method of osteosynthesis (P 0.007). The postoperative scintimetric ratio was influenced by the method of osteosynthesis (P 0.0003), fracture displacement (P 0.004) and by the presence of a posterior fragment (P 0.03). Reduction of the fracture and positioning of the osteosynthesis were to a large extent within the accepted limits. This may explain why the previously well documented negative effects of malpositioning of the osteosynthesis and inferior reduction were not demonstrated to influence the rate of healing-complications. We conclude that neither patient age, sex nor preoperative fracture variables, with the exception of the extent of fracture displacement, can be used to predict radiographic healing-complications in femoral neck fractures.

Abstract
Totally, 185 patients with a mean age of 80 years treated by Austin-Moore cementless hemiarthroplasty for an acute femoral neck fracture were compared with age- and sex-matched nonfracture controls. There were 22 early complications, notably 7 percent dislocation and 4 percent deep infection. Later on, two acetabular protrusions and four loosenings of the prosthesis requiring admission were recorded. Mortality after the fracture was 12 percent above the control level at 3 months, 19 percent at 12 months, and 21 percent at 18 months. The 5-year mortality was about 60 percent in both patients and controls. The average loss of life in the fracture group compared with the control group was 425 days. After a mean follow-up period of 6 years, 24 of the 65 patients still alive and the 49 of the 60 controls were living in their own homes; and 28 of the patients were institutionalized in a hospital unit for chronic care. Half of the patients and most of the controls were able to move about independently. We concluded that Austin-Moore hemiarthroplasty is associated with serious complications that prevent social rehabilitation and function to reach acceptable levels.

Abstract
We report a study of 168 consecutive patients (171 prostheses) with a displaced femoral neck fracture and a physiologic age older than 75 years who were treated with an uncemented bipolar Monk hard-top hemiarthroplasty. Four prostheses dislocated postoperatively, but none after discharge. Two prostheses were later extracted. Five patients sustained an ipsilateral femoral fracture. Totally, 7 patients (4 percent) were reoperated on. One year after the operation, 22 percent of the patients were dead. An increased mortality rate was recorded during the first 6 months after surgery. At follow-up 6 (3-9) years after the operation, 4 of the 62 patients alive had weight-bearing pain. Three had subsidence of the prosthesis, but none had protrusion of the acetabulum. Ninety-five percent of the patients were free from complications requiring a reoperation or outpatient evaluation.

Abstract
32 patients, suffering from Parkinson's disease, had internal fixation of femoral neck fractures. In 24 displaced fractures, 6 nonunions and 3 segmental collapses were seen; and in 8 undisplaced fractures, 1 case of segmental collapse was diagnosed. Healing complications were thus seen in one third. Total hip replacement for healing complication was performed in 3 of 32 patients. 9 patients died within 2 years. No difference in the rate of healing or mortality was detected compared with hip fracture patients without Parkinson's disease. Our study does not support primary arthroplasty for femoral neck fracture in patients with Parkinson's disease.

Abstract
Totally, 191 consecutive patients with femoral neck fractures during 1984 and 1985 had internal fixation with hook-pins and were prospectively investigated. Within 2 years, 62 patients had died and 47 had developed healing complications, 30 of whom had been treated with total hip replacement. Thus, 82 healed without complication. Forty-one of 47 patients without other handicaps affecting their walking ability considered their gait as good as it was preoperatively; 45 used no walking aids or a cane. Nine of 35 patients with a nonfracture-related disease affecting their walking ability managed to walk with or without a cane; 13 considered their walking ability unaltered compared with their prefracture state. Three of 82 patients complained of pain on walking and 2 of pain at rest. All but 1 could flex their hip 90 degrees or more. We believe that the function after internal fixation of cervical hip fracture with uncomplicated healing is superior to that achieved by primary hip replacement; primary replacement is recommended only in rheumatoid patients with displaced fractures.
