Low rate of secondary surgery and implant removal following superior, precontoured plating of midshaft clavicle fractures

Background

Surgical fixation of midshaft clavicle fractures with a single 3.5 mm superior clavicular plate has been associated with a high rate of hardware removal due to symptomatic hardware. Because of this, dual-plating techniques with lower-profile implants have been proposed. However, dual-plating systems have disadvantages, including increased cost and increased surgical morbidity. The aim of this study was to define the rate of symptomatic hardware removal for all midshaft clavicle fractures.

Methods

We retrospectively reviewed information on all patients from 2014 to 2018 at a single level 1 trauma institution with surgeries performed by two fellowship-trained orthopedic trauma surgeons. Documented removal of hardware and the reason for removal were recorded. We then contacted all patients at their listed telephone number to confirm the hardware was still in place and to administer patient outcome questionnaires. If patients did not answer, attempts were made to contact them multiple times on multiple days. Those who were not reached but had documented hardware removal were included in the total number of patients with hardware removal.

Results

The search revealed 158 patients, of whom 89 (61.8%) were included in the study. Average follow up was 4.09 years (range 2.02-6.50 years). Five patients (5.56%) underwent hardware removal. Removal was for symptomatic or irritating hardware in two of these patients (2.22%). Average abbreviated Disability of Arm, Shoulder, and Hand score was 6.27, and average American Society of Shoulder and Elbow Surgeons shoulder score was 93.6.

Conclusion

In our series, the rate of symptomatic hardware removal was 2.22%, well below reported removal rates. Hardware removal rates for prominent symptomatic superior clavicular plates may be significantly lower than previously reported, and these fractures may be adequately treated with a single, superior plate.

Comparison of clinical outcomes with proximal femoral nail anti-rotation versus bipolar hemiarthroplasty for the treatment of elderly unstable comminuted intertrochanteric fractures

BACKGROUND

Although proximal femoral nail anti-rotation (PFNA) and bipolar hemiarthroplasty (BHA) are selected by most of the orthopaedic surgeons for elderly intertrochanteric fractures (ITFs) patients, there is still no consensus on the superiority of PFNA and BPH for the elderly with unstable comminuted ITFs. The study aims to compare the curative effects of PFNA and cementless BHA on unstable comminuted ITFs in the elderly.

METHODS

From January 2012 to December 2016, we retrospectively reviewed 62 ITFs patients up to the inclusion and exclusion criteria in the study. Depending on the type of surgery, the patients were divided into two groups: Group BHA (n= 30) and Group PFNA (n = 32). The ITFs were classified according to Evans-Jensen. Hospitalization time, operation time, bleeding loss, weight bearing duration, Harris hip scores, 10-m walking speed, gait and postoperative complications were compared between the two groups.

RESULTS

There was no significant difference between the groups in hospital stay (P > 0.05). The BHA group trended to have a shorter operation time and a larger volume of blood loss (P < 0.01).The weight bearing duration was shorter in the BHA group than the PFNA group (P < 0.05).The Harris hip score was higher, the 10-m walking speed was faster and the gait was better in group BHA than group PFNA at three months postoperatively (P < 0.05), but there was no significant difference between the two groups at 6 and 12 months postoperatively (P > 0.05). There was no significant difference in postoperative complications between the two groups (P > 0.05).

CONCLUSION

The BHA allows an earlier return to weight-bearing activity, but ultimately has the same effective treatments as the PFNA for the elderly with unstable comminuted ITFs.

Bipolar Hemiarthroplasty should not be selected as the primary option for intertrochanteric fractures in elderly patients aged 85 years or more

This study aimed to compare the early outcome of proximal femoral nail antirotation (PFNA) and bipolar hemiarthroplasty (BPH) in elderly intertrochanteric fractures (ITFs) patients aged 85 years or more.This is a prospective cohort study, and we analyzed 120 elderly patients aged 85 years or more presented with ITFs who underwent BPH and PFNA between January 2017 and July 2018. 84 patients treated with PFNA were set as Group A, and 36 patients treated with BPH were set as Group B. Data such as gender, age, period of follow-up, fracture classification (according to Evans-Jensen classification), preoperative ASA (American Society of Anesthesiologists) physical status, interval between injury and operation, method of anaesthesia, duration of operation time, blood loss during surgery, time of weight bearing after operation, incidence of complications 2 weeks after operation, mortality rates and Harris Hip Score 12 months after operation were recorded and compared.There are no statistically significant differences when compared general data in patients from group A and B (P > .05). Operation time in Group A is less than Group B (103.33, 40-230 min vs 122.64, 75-180 minute, P < .01). Blood loss during surgery in Group A is less than Group B (70.24, 50-100 mL vs 194.44, 100-500 mL, P < .01). Time of weight bearing after operation in Group A is longer than Group B (50.70, 7-100 days vs 6.67, 4-14 days, P < .01). Incidence of complications 2 weeks after operation in Group A is less than Group B (14.12% vs 36.11%, P < .01). Mortality rates 12 months after operation in Group A is similar with Group B (13.10% vs 19.44%, P > .05). Harris Hip Score 12 months after operation in Group A is similar with Group B (64.64,0-91 points vs 64.41, 0-90 points, P > .05).Although BPH and PFNA have similar functional outcome and mortality rates 12 months after operation, BPH has more postoperative complications in elderly patients aged 85 years or more with ITFs, Bipolar Hemiarthroplasty should not be selected as the primary option for ITFs in elderly patients aged 85 years or more.

Management of Lower Extremity Fractures in the Elderly: A Focus on Post-Operative Rehabilitation

Fractures in the elderly population are increasing in incidence and represent a rising burden of disease. It is difficult for the elderly population to adhere to restricted weight bearing, and immobility poses significant risks and increased morbidity. Therefore, a primary goal of fracture management in the elderly population is early post-operative weight bearing. This review examines published literature regarding lower extremity fracture management in the elderly, with a focus on post-operative rehabilitation. While extensive literature supports early weight bearing after hip fractures in the elderly, further research is warranted to provide guidelines for management of other lower extremity fractures in this population.

Bipolar Hemiarthroplasty should not be selected as the primary option for intertrochanteric fractures in elderly patients

Intertrochanteric fractures (ITFs) in the elderly are still a big challenge for clinical doctors. Although proximal femoral nail antirotation (PFNA) and bipolar hemiarthroplasty (BPH) are selected by most of the orthopaedic surgeons for elderly ITFs patients, there is still no consensus on the superiority of PFNA and BPH for ITFs in elderly. In this study, we hypothesized that BPH should not be selected as the primary option for ITFs in elderly patients, and analyzed clinical data of 202 elderly ITFs patients aged 80 years or more treated with PFNA (Group A) and BPH (Group B) to compare the early outcome of PFNA and BPH for ITFs in elderly patients aged 80 years or more. We found that operation time and blood loss during surgery in group A are less than in Group B. Time of weight bearing after operation in Group A is longer than in Group B. Incidence of complications 2 weeks after operation in Group A is 9.29% less than 25.81% in Group B (χ² = 9.539, p = 0.002). Mortality rates 12 months after operation in Group A is 11.43% similar with 19.35% in Group B (χ² = 2.261, p = 0.133). Harris Hip Score 12 months after operation in Group A is 68.00 ± 29.11 points similar with 65.73 ± 33.29 points in Group B (t = 0.490, p = 0.625). Therefore, for elderly ITFs patients aged 80 years or more, BPH should not be selected as the primary option for ITFs in elderly patients.
