Primary hemiarthroplasty for treatment of unstable pertrochanteric femoral fractures (AO/OTA Type 31 A2.3) in elderly osteoporotic patients

Surgical Management of Unstable Trochanteric Fractures of the Femur Using Cemented Hemi-Prosthesis in Elderly Patients: A Prospective Study

Background In the case of elderly patients suffering from osteoporosis, the primary objectives of addressing comminuted intertrochanteric fractures are centered upon the recuperation of the patients' pre-fracture levels of activity, the expeditious promotion of full weight-bearing capacity, and the minimization of the likelihood of further surgical interventions. The adoption of hemiarthroplasty as a method for comminuted intertrochanteric fractures is proven as a means of hastening the recovery process, enabling early weight-bearing and mitigating the problems associated with extended bed rest. The outcomes that resulted from the application of this technique will be evaluated and analyzed as part of this study's objectives. Methodology A prospective study was conducted over the course of one year at a tertiary care hospital in the northern part of India. The study comprised a total of 30 individuals; however, unfortunately, one of the patients could not be located for further analysis. Patients of either gender in the age group of over 60 years old and with unstable osteoporotic intertrochanteric fractures were included (AO Foundation/Orthopaedic Trauma Association type 31-A2.2, A2.3, or 31-A3 group). Patients were observed at one, three, and six months after the surgical operation. The Harris Hip Score (HHS) was used for the functional outcome evaluation. Results Throughout the course of our analysis, we saw an increase in the overall HHS that was statistically significant. The HHS exhibited a mean value of 34.33 during the period of discharge, with a range of 32 to 39. It increased to 55.34 (range = 52-59) after one month of follow-up, and it continued to rise to 85.03 (range = 63-89) after three months of follow-up. It is important to note that the mean HHS reached 95.24 (range = 63-98) by the sixth month of follow-up. The study showed a statistically significant upward trend in HHS scores across all time periods (p < 0.001). Conclusions Early postoperative ambulation was made possible with the use of cemented prostheses, which contributed to patients' overall improvements in their functional results. Cemented primary bipolar hemiarthroplasty has emerged as a promising alternative for the treatment of unstable intertrochanteric fractures. The enhanced functional outcomes measured by the HHS provide evidence of this. The transtrochanteric technique has shown advantages in retaining the anatomical integrity of external rotators, minimizing the necessity for their resection, and reducing the danger of sciatic nerve injury. These advantages were displayed by the transtrochanteric approach. Moreover, owing to the implementation of wiring techniques, the larger trochanter could be conserved, resulting in enhanced postoperative recovery and expediting the return to the preoperative condition. When compared with other techniques of internal fixation, the utilization of cemented bipolar hemiarthroplasty demonstrated much-reduced rates of complications, such as the need for further surgery and implant failure.

Study of outcomes of cemented hemiarthroplasty for comminuted intertrochanteric fractures in the elderly

Aims & objectives

To assess the functional outcomes of the unstable intertrochanteric fractures in the osteoporotic individuals treated by primary cemented hemiarthroplasty by early mobilization and immediate weight-bearing, restoration of limb length, and gait Assessment.

Materials and methods

It is a prospective study of 17 elderly patients with comminuted intertrochanteric fractures managed with cemented hemiarthroplasty attending to the Department of Orthopaedics, Government General Hospital, Rangaraya medical college, Kakinada.

Results

17 cases of unstable intertrochanteric fractures were treated with cemented bipolar hemiarthroplasty. The average follow-up period was 12 months. The average age was 72.75 years with a standard deviation of 5.56. Most (82.3%) of the patients presented with Boyd and Griffin type 2 fracture. The functional assessment by HHS showed good to excellent outcomes in most of the patients (64.7%). 2 patients had abductor weakness, 1 patient had superficial surgical site infection, one had hypotension, and 1 patient had bedsore.

Conclusions

Primary cemented bipolar prosthetic replacement in comminuted intertrochanteric fractures in the elderly patients provide s painless, stable, and mobile hip joint so that we can institute early postoperative mobilization which can avoid the consequences of prolonged recumbency. Hemiarthroplasty also avoids a second procedure in such elderly patients with multiple comorbidities as there is a high risk of failure of internal fixation in patients with poor bone quality, subjecting them to a second surgery and anaesthesia being a risky proposition.

Evaluation of functional outcome and comparison of three different surgical modalities for management of intertrochanteric fractures in elderly population

INTRODUCTION

The purpose of this study was to compare the role of the various surgical modalities ie, Hemiarthroplasty (HA), Dynamic Hip Screw (DHS), Cephalo-medullary nail (CMN) in the management of intertrochanteric fractures in elder patients with comparison of the results and assessment of the complications encountered with each method.

METHODS

Total 105 adult patients having intertrochanteric fractures managed during July 2013 to December 2018 at tertiary trauma care centre and followed for minimum 12 months were included in the study. Patients were divided into three groups. Primary hemiarthroplasty was done in 35 patients (group A) while DHS and PFN was done in 35 patients each in group B and group C respectively. Functional evaluation was done using Modified Harris Hip score (HHS) at different intervals while ambulatory function was measured using the Parker Mobility Score.

RESULTS

The mean age of patients was 72.14±2.9 years. Mean operative time and blood loss in group A was significantly higher than the other two groups. Hemiarthroplasty group could ambulate earlier than DHS/PFN group. Mean HHS at final follow up was 85.40±7 in group A while in group B and group C these values were 76.36±16.45 and 86.85±10.52 respectively. HHS was significantly higher (P, 0.01) in hemiarthroplasty group in comparison to DHS group. Post-operative complications were comparable in all the groups.

CONCLUSION

We support the use of hemiarthroplasty for unstable intertrochanteric fracture in elderly patients with lesser failure rates, early mobilization and better functional outcomes. Early mobilization and less hospital stay should be the goal of every surgical procedure in the elder population.

[Endoprosthetic treatment of pertrochanteric femoral fractures with concomitant coxarthrosis : A consecutive observational study with a control group]

INTRODUCTION

Hip replacement for pertrochanteric femoral fractures (PF) is challenging due to its complexity. Studies regarding this procedures are limited, therefore this monocentric study was conducted. The null hypothesis was no effect between replacement and internal fixation according to revision and mortality.

MATERIAL AND METHODS

Using an electronic database, patients who had received a hip replacement between 2007 and 2016 for a PF with a concomitant coxarthrosis were included in the study. The comparison group consisted of 1000 osteosyntheses for the treatment of PF. With the exception of coxarthrosis, the same inclusion and exclusion criteria were defined. Surgical revision and mortality with endpoint 2 years after the operation were the primary outcomes. At least 2 years postoperatively, a telephone follow-up was done with living patients who underwent replacement.

RESULTS

Records of 90 hip replacements and 15 baseline characteristics were reviewed (e.g., age, sex, body mass index, preoperative blood values, ASA classification, dementia, fracture classification). Replacement was significantly associated with a delay to operation (p < 0.001), a longer duration of operation (p < 0.001), an increased blood loss (p < 0.001), more blood transfusions (p < 0.001), and a longer inpatient stay (p = 0.026). According to the primary outcome, the mortality rate (p = 0.002) and the rate of infection in a subgroup analysis (p = 0.031) were also significantly increased. Using Cox regression, replacement was associated with a significantly higher probability of a shorter survival rate (odds ratio: 1.438, confidence interval: 1.054-1.962). Therefore, the null hypothesis was rejected. At the follow-up 6.1 years postoperatively (3.2-8.6 years), only 17 patients with replacement (20%) were still alive. The mean Parker mobility score was 5.0 points (range 3-9 points).

CONCLUSION

In this study, a significantly higher rate of infection and mortality was observed in patients with hip replacement for a PF and with a concomitant coxarthrosis; compared to osteosynthesis of PF without coxarthrosis. Further studies are mandatory to provide the appropriate treatment for patients with this fracture pattern.

Comparative evaluation of postoperative health status and functional outcome in patients treated with either proximal femoral nail or hemiarthroplasty for unstable intertrochanteric fracture

PURPOSE

This study aimed to compare functional recovery and change in morbidity status from the preoperative levels among patients who underwent two different surgical treatments for unstable intertrochanteric fracture.

METHODS

This retrospective comparative study enrolled 140 patients (aged >80 years) who were referred to two hospitals. Of these, 64 were treated using proximal femoral nail (PFN) and 76 were treated using hemiarthroplasty (HA). To evaluate functional recovery, primary outcome measures were cumulative illness rating scale (CIRS) score to evaluate changes in morbidity status, activity of daily living (ADL) index, and mobility scores.

RESULTS

The proportion of patients who experienced increased CIRS scores in the HA group was higher at the 3-month follow-up (p = 0.02) but similar at the 6-month follow-up (p = 0.2) in comparison to the PFN group. Treatment with HA, American Society of Anesthesiologists scores of 3-4, and lower, preoperative ADL indexes were the major predictors of increased postoperative CIRS score. Impaired ambulatory ability and the need for walking aids were significantly higher in the PFN group at the 3-month follow-up (p = 0.01 and p = 0.02, respectively) but similar at the 6-month follow-up with respect to the HA group. PFN treatment and high patient body mass index were the major predictors of decreased ambulatory ability at postoperative 3 months.

CONCLUSION

HA has several advantages, including early mobilization and decreased dependency. However, it is associated with greater blood loss, a higher need for blood transfusion, and longer surgical duration than PFN, all of which are predisposing factors for significantly higher risk of reduced CIRS scores.

Dual Mobility Acetabular Cup Versus Hemiarthroplasty in Treatment of Displaced Femoral Neck Fractures in Elderly Patients: Comparative Study and Results at Minimum 3-Year Follow-up

Background:

Hip fractures are serious injuries associated with relatively high mortality rates and disabilities, commonly seen in elderly persons. There is an ongoing debate regarding the advantages of various hip arthroplasty devices. This study aimed to analyze the long-term advantages of 2 different surgical procedures and assess if the dislocation rate, Harris Hip Score (HHS), and functional independence measure (FIM) are more favorable in dual mobility (DM) than those in hemiarthroplasty (HA).

Hypothesis:

Dual mobility procedures provide better postoperative outcomes than HA in terms of HHS, FIM, and dislocation rate.

Materials and Methods:

The survey was a prospective, comparative interventional single-blinded study performed at the University Clinical Center of Kosovo, a tertiary health-care institution. A total of 94 patients underwent DM or conventional bipolar HA for repair of displaced femoral neck fractures within 2 weeks of injury. Primary outcomes were postoperative dislocation rate, FIM, and HHS. Secondary outcomes included duration of surgery, estimated intraoperative blood loss, time to first postoperative full weight-bearing, time to walking ability with and without crutches, mortality rate, and postoperative infection rate.

Results:

There were no significant differences for most parameters between the groups. We found a significant difference in the dislocation rate between the 2 groups, wherein there were no dislocations in the DM group and 3 dislocations in the HHS group (0% vs 6.4%). In terms of postoperative HHS at 12 months and 3 years, DM provided better outcomes (<0.034 and <0.014, respectively).

Discussion:

Dual mobility compares favorably to HA in terms of dislocation rate and HHS, while no difference was found for FIM. In order to have a more complete overview, we recommend more intense long-term studies including several heterogeneous parameters to compare the clinical outcomes between DM and HA.

Level of evidence (with study design):

Level II.

Is rigid fixation of the greater trochanter necessary for arthroplasty of intertrochanteric fractures?

INTRODUCTION

Stable fixation of the greater trochanter fracture fragments is necessary in arthroplasty of intertrochanteric hip fractures, as nonunion of the greater trochanter fracture comminution may result in impaired function or dysfunction of the abductor lever arm.

HYPOTHESIS

The ethibond suture technique is an efficient method for fixation of the greater trochanter fracture fragments.

MATERIALS AND METHODS

A total of 47 cases were studied. The mean age of the patients was 80.6 years, and the minimum follow-up was 6 months. Radiologic evaluation was done by examination of greater trochanter healing and measurement of migration of the greater trochanter fragment. Functional evaluation was done by comparison of pre-injury and postoperative ambulation status.

RESULTS

The mean migration of the greater trochanter fragment with ethibond sutures was 5.98mm. Union was achieved in 76.6%, and the nonunion rate was 23.4%. 86.9% of patients had no difference in ambulation or had a difference of only 1 level by the Koval score after treatment compared to their pre-injury status.

DISCUSSION

The ethibond suture technique provides good fixation of the greater trochanter fragments in arthroplasty of intertrochanteric hip fractures.
