[Fractures of the distal radius in patients over 70 years old: Volar plates or K-wires?]

Experience of Kapandji technique in treating Colles' fracture in central region of Vietnam

Introduction: Extra-articular fractures of the distal radius, known as Colles’ fractures, are very common. The optimal management of Colles’ fracture is still controversial. The Kapandji technique is one option for orthopedic surgeons to maintain reduced fractures, however, the effectiveness of this method is no clear consensus. This study aims to access Colles’ fracture treatment by the Kapandji technique with our experiences. Methods: This prospective study of 33 patients treated with three K-wires intra-focal fractures by the Kapandji procedure for Colles’ fractures at Hue University of Medicine and Pharmacy Hospital in Vietnam between February 2017 and May 2019. The functional outcome of the patients was assessed by the demerit score system of Gartland and Werley, and the quality of reduction was elevated on radiographic as well at 3, 6, 12, and 24 weeks postoperative. Results: 33 patients’ mean age is 54.64 ± 18.00; After 24 weeks of postoperative follow-up, 78.79% presented excellent, 21.21% good, and there are not any fair or poor cases on the functional outcome. All patients achieved complete fracture union at 12 weeks postoperative. The average immediate postoperative radial length was 9.85 mm, the radial inclination was 20.64°, and the volar tilt was 9.2°. Conclusion: The study emphasizes that the Kapandji technique in Colles’ fracture treatment is simple and possible to bring a satisfactory outcome and fast recovery.

Treatment options in extra-articular distal radius fractures: a systematic review and meta-analysis

PURPOSE

This systematic literature review aimed to make a detailed overview on the clinical and functional outcomes and to get insight into the possible superiority of a treatment method for extra-articular distal radius fractures.

METHODS

Embase, Medline, Cochrane Library, Web of Science, and Google Scholar were searched for studies describing treatment results. Five treatment modalities were compared: plaster cast immobilization, K-wire fixation, volar plating, external fixation, and intramedullary fixation.

RESULTS

Out of 7,054 screened studies, 109 were included in the analysis. Overall complication rate ranged from 9% after plaster cast treatment to 18.5% after K-wire fixation. For radiographic outcomes, only volar tilt in the plaster cast group was lower than in the other groups. Apart from better grip strength after volar plating, no clear functional differences were found across treatment groups.

CONCLUSION

Current literature does not provide uniform evidence to prove superiority of a particular treatment method when looking at complications, re-interventions, and long-term functional outcomes.

Functional Outcome of Distal Radial Fractures in Patients With a Mean Age of 75 Years at a Mean Follow-Up of 5.4 Years

Purpose

Distal radial fractures in the elderly are common and present in a wide spectrum of severity. Their management is varied. The aim of this retrospective case review is to evaluate the late functional outcome of surgically treated distal radial fractures in the elderly population.

Methods

Forty-two patients (36 female and six male) were surgically treated for an unstable distal radial fracture. The mean age of the patients was 75 years. Frykman classification was used to assess the severity of the injury. Surgical options used were reduction and K wires (19 patients) or open reduction and internal fixation (ORIF) using volar distal radial plate fixation (23 patients). At a mean follow-up of 5.4 years, a validated questionnaire (Patient Rated Wrist Evaluation-PRWE) of the functional ability was completed for each patient.

Results

The outcome in both groups was satisfactory (PRWE 40-50) with no significant statistical difference, however, a better functional outcome (<40 PRWE) was achieved in the K wire group compared to the ORIF group. Factors such as post injury fear from fall, weakness of grip, wrist pain, and other comorbidities altered the predicted functional outcome score.

Conclusion

In conclusion, surgically treated fractures in the elderly generally lead to good outcomes. However, confounding factors can contribute to unpredictable results despite good surgical reduction and fixation.

Comparative results of radius distal AO type C1 fractures of elderly women by two different techniques

ackgrounds: We evaluated clinical and radiographic outcomes of volar locking plates and close reduction with percutaneous pinning treatment approaches for elderly female patients with AO type C1 simple intra-articular distal radius fractures.

PATIENTS AND METHODS

We conducted retrospective studies of 72 elderly female patients with AO type C1 simple intra-articular DRFs treated with VLPs or CRPP, from 2012 to 2018. The patients were divided into two groups: There were 38 patients in VLP group and 34 patients in CRPP group. Periodic clinical and radiological evaluation was performed at 2nd, 4th, 6th, 8th weeks and in 6 and 12 months intervals for all patients. We recorded the patient-rated wrist evaluation scores, flexion, extension, supination and pronation degrees and radiographic outcome scores at the end of 6th and 12 months after surgery.

RESULTS

A total number of 72 patients were studied. 38 patients were treated with VLP and 34 patients were treated with CRPP .The mean age of the patients was 70,5 years. Comparing the PRWE scores, the VAS scores and the ROM degrees between the 2 groups yielded no significant difference at any time point between 6 months and 1 year. There were no differences in radiographic outcomes at the latest reported follow up between the two interventions and there was no significant difference in the complication between the 2 groups (VLP 6 and CRPP 6) complications.

CONCLUSIONS

Complicated surgeries should be avoided because of specific problems in women aged 60 years or older. Our study show that VLP and CRPP techniques had little differences and similar clinical and radiographic results.

What happens to the posterior comminution in extra-articular fractures of the distal radius treated with volar locking plates?

Extra-articular fractures of the distal radius with posterior displacement are typically treated with volar locking plates. However, this fixation method does not address the posterior comminution, which seems to have no impact on the final result. The purpose of this study was to determine the fate of the posterior comminution. This was a retrospective study of 22 patients over 50 years old with a distal radius fracture. A preoperative computed tomography (CT) scan was performed to evaluate the comminution. All fractures were fixed with a volar locking plate. All patients underwent a bone density scan. Patients were reviewed at 6 months post-operative to determine their clinical, radiological and functional outcomes. The CT scan was performed again to determine the fate of the comminution. At 6 months post-operative, 82% of patients had an oval metaphyseal defect. The mean volume of this defect was 1.86 mL. The contents of this defect most closely resembled fat. There was no statistical link between the defect's volume and the various parameters studied. On the other hand, the defect's density was positively related to the functional outcome and negatively related to the patients' body mass index. Because of the compression experienced by the cancellous bone, a distal metaphyseal defect often persists after consolidation in dorsally displaced distal radius fractures. The posterior comminution is ultimately of little consequence.

Treatment goals for distal radius fractures in 2018: recommendations and practical advice

The goals of distal radius fracture treatment in patients above 65 years of age would not change over time if the fracture were the only factor to consider. However, people change, and fixation methods also change. Since this fracture heals in nearly every case and volar plates have eliminated the worry of malunion, we are left with two main goals. In active patients with weakened bones, the aim is to help them regain their quality of life as quickly as possible while avoiding iatrogenic conditions. This compromise is possible because of new tools-but at what price?

Incidence of osteosynthesis of members in France

PURPOSE

Little data is available on the number of osteosynthesis of limbs in a country. Incidence of osteosynthesis is an essential element for the formation and organization of care. Based on the data from the work of the Hospital Information Technology Agency ( http://www.atih.sante.fr/ ) and available in open access, we wanted to know the incidence of the number of osteosynthesis performed in France and their evolution over ten years between 2006 and 2015.

METHODS

The data analyzed are derived from the website of the technical agency of information on the hospitalization (ATIH).

RESULTS AND CONCLUSIONS

In France, in 2015, 267,999 limb osteosyntheses were performed. Between 2006 and 2015, the number of osteosynthesis increased by 9.1%. The incidence of limb osteosynthesis is 403.7 per 100,000 people, rising 3.9% between 2006 and 2015. In comparison, the incidence of hip prostheses increased by 12.6%, knee prosthesis by 57.4%. The main bias of the study is of course the quality of the coding of the surgeons and the establishments, a type of fracture that can enter into one or several categories of acts. In ten years, the incidence of osteosynthesis has increased little in France. The evolution is more pronounced on fractures affecting mainly the elderly, fracture of the upper end of the femur, fracture of the distal end of the radius and fracture of the ankle. The incidence of many acts of osteosynthesis is very low and therefore responsible for a weak experience for most surgeons.

[Treatment of extra-articular distal radius fractures in active elderly patients]

Extra-articular distal radius fractures in active elderly patients are common and predominantly affect females. The high number of patients lost to follow-up compromises the evaluation of outcomes. Treatment aims to control the comminution and allow fast recovery of pre-injury activity levels. Fixation with volar locking plates is the gold standard. The role of bone substitutes in this type of injury is unclear.

Early postoperative improvements in the QuickDASH score after distal radius fracture are related to the type of surgical treatment

The goal of this prospective study was to evaluate the real-life experience of 52 patients and their recovery kinetics in the first 6 weeks after surgical treatment of distal radius fractures. The fractures were treated with either a fourth-generation volar locking plate (34 patients, mean age 67 years, range 54-82) or by percutaneous pinning (18 patients, mean age 56 years, range 43-69). These patients were evaluated every week for 6 weeks with the QuickDASH (QD) questionnaire. A lower QD score indicated that the patient's physical function and symptoms had improved. At postoperative week 1, all the patients who had undergone percutaneous pinning had a QD of 80 (out of 100). One-third of patients who had undergone plate fixation had a QD of 80, while the remainder had a QD of 65. Out of all the patients who had a QD of 80 at postoperative week 1, the patients who had undergone plate fixation improved more quickly. After 6 weeks, the patients who had undergone plate fixation had a greater reduction in the QD (50 points) than the ones who had undergone pinning (30 points). Although the direct costs of locking plate fixation are 10 times higher than those of K-wire pinning, evidence suggests that these plates reduce the indirect costs. This study has shown that a patient's recovery rate, day-to-day life and physical function are better over the first 6 weeks postsurgery when the distal radius fracture is fixed with a locking plate.

Type C distal radial fractures treated with conventional AO plates: an easy and cost-saving solution in a locking plate era

PURPOSE

C-type distal radial fractures remain challenging fractures. Currently locking plates are very popular because of their length preserving, stability. A considerable drawback is the high cost. Since 2003 we have been using mini AO plates (2.7 mm) as an alternative. We analysed our results and performed a cost analysis.

METHODS

Retrospective analysis was performed of all patients operated upon between 2003 and 2008 for C type distal radius fractures. Reduction was achieved with mini AO plates, applied in a buttress fashion, with ligamentotaxis. Rehabilitation consisted of immediate mobilisation. Pre- and postoperative X-rays, operative results and patient charts were reviewed. Furthermore, we prospectively evaluated the functional results using VAS, DASH and Mayo wrist scores. Lastly, we assessed the implant costs and compared them to locking plates.

RESULTS

Thirty-four patients were treated with a mean age of 49 years. Mean radial shortening improved 2 mm; dorsal and radial angulation improved 23 and 4°, respectively. At consolidation (eight weeks) the average radial shortening was 0.75 mm, a volar angulation of 3°, and 21° of radial angulation. Functional results were excellent, demonstrated by a mean VAS score less than 1, a DASH score of 12 and a Mayo wrist score of 87. Compared to locking plates, there was an overall reduction in material costs of 15,300 Euro.

CONCLUSIONS

Our technique has excellent biomechanical stability, enabling immediate functional rehabilitation, good anatomical and functional outcome with significantly lower costs.

A comparative study of Colles' fractures in patients between fifty and seventy years of age: percutaneous K-wiring versus volar locking plating

PURPOSE

This retrospective study was to compare the clinical outcomes of volar locking plating (VLP) and percutaneous Kirschner wiring (PKW) for the management of displaced Colles type distal radius fractures in patients between 50 and 70 years old.

METHODS

There were 31 elderly patients with displaced Colles' fractures treated by VLP. We compared them to 31 match-paired patients treated by PKW. The patients were matched according to age (within five years) and sex. All patients were followed up retrospectively for at least 12 months. The functional outcomes and radiological results were compared between the two groups.

RESULTS

All fractures healed within three months. There were two complications (6.5%) in the PKW group and one complication (3.2%) in the VLP group. At final follow-up, wrist flexion, extension, and ulnar deviation were significantly better in the VLP group compared with the PKW group (all p values<0.05). According to modified Green and O'Brien criteria, the VLP group showed a trend towards increased rate of satisfactory outcome compared with the PKW group (p = 0.09).

CONCLUSION

For the treatment of displaced Colles' fractures in patients between 50 and 70 years old, both groups had high union rate and low complication rate. However, better functional results can be expected in association with open reduction and volar locking plating.
