Determining the Borderline Anatomical Parameters for Better Functional Outcome of Colles Fracture: A Prospective Study[*]
Article in several languages: português | EnglishAbstract
Objective The treatment of Colles fracture can deform the wrist. Some studies claim the resulting deformity rarely hinders daily activities, whereas others report the opposite; thus, anatomical reduction is desirable. Our objective was to analyze the anatomical and functional results of Colles fracture to find out the values of individual parameters corresponding to the best functional outcome.
Methods The present prospective study included 70 elderly patients with Colles fracture. All patients were managed conservatively. The anatomical parameters were evaluated by measuring dorsal angulation, radial inclination, and radial height, and they were assessed as per Stewart et al. The functional result was assessed by the Mayo wrist score. The results were analyzed using the chi-squared test of association, and a p-value < 0.001 was considered statistically significant and to examine strengths of associations; we computed odds ratios (ORs) with 95% confidence intervals (CI).
Results Excellent and good results were obtained in 68.5% of the cases anatomically and 78.5% functionally, which was statistically significant (p = 0.0009). Out of the three anatomical parameter dorsal angulation < 10° and loss of radial inclination < 9° showed statistically significant association with functional results (p = 0.0006), but loss of radial height < 6 mm did not (p = 0.0568), which became significant when loss of radial height was kept < 4 mm (p = 0.00062).
Conclusion Fractures with anatomical reduction have better functional results. The acceptable borderline anatomical parameters for obtaining excellent or good functional results are dorsal angulation < 10°, loss of radial inclination < 9°, and loss of radial height < 4 mm.

Introduction
Anatomically upper limb and that to hand and wrist is meant for precision. The singular anatomy of volar tilt, radial inclination, and radial height of the distal end of the radius gives the wrist the amazing freedom of movement necessary for precision work that sets the humans apart from the rest of the world. The disadvantage of the upright posture and of the high degree of movements is that the upper extremity is more prone to injury than the lower limbs.[1] Fractures involving the distal end of the radius are the most common and account for ∼ 17.5% of all fractures.[1] [2] It has bimodal age distribution with one peak at 6 to 10 years and another peak at 60 to 70 years.[2] Elderly women are seven times more prone to this type of injury, which may be due to postmenopausal osteoporosis.[3] The mode of injury is mostly due to simple fall with outstretched hands.[4] The fracture pattern is typically distal metaphyseal, involving one inch from the distal end of radius with its classical dorsal comminution, dorsal angulation, dorsal displacement, radial displacement; this type of lesion is named Colles fracture, after Sir Abraham Colles, who first described it in 1814.[4] Until today, conservative management with a cast below the elbow with wrist in a neutral to mild flexion position and ulnar deviation is accepted as standard treatment for elderly patients with low physical demands.[5] The healing process is usually accompanied by deformity, which may be skillfully treated in up to 60% of cases.[6] [7]
There is a discussion of whether this deformity impairs the functional outcome in aged patients or not. There are numerous publications regarding this but giving confusing messages. Most of them state Colles fracture does require special attention as the resulting deformity rarely damages the wrist function.[5] [8] Some say even small changes in the anatomical parameters of the distal end of the radius can lead to poor functional outcome in up to 17% of cases.[9] Others say the functional outcome following Colles fracture is multifactorial and not necessarily anatomical reductions as deciding entity.[10]
Hence, this study was conducted to assess the anatomical and functional results of Colles fracture treated conservatively in elderly people and to evaluate the correlation between individual anatomical parameters and functional results to determine borderline values of each of them corresponding with a better functional outcome.

Material and Methods
After obtaining ethical committee approval and patients consent, the data were collected and analyzed prospectively for 70 patients with Colles fractures, who attended the Out Patient Department (OPD) and emergency care unit between May 2016 and May 2020. Patients between 60 and 80 years of age, with unilateral, extraarticular distal radius closed fractures were included in the present study; individuals with bilateral distal radius fracture, intraarticular fracture, and open fracture were excluded.
Posteroanterior (PA) and lateral views X-rays of both wrist (as case and control) were taken. The fractures were classified according to the Arbeitsgemeinschaft für Osteosynthesefragen/Orthopedic Trauma Association (AO/OTA) classification (AO/OTA-2R3A2.2). A hematoma block (with 1 ml of 2% lignocaine) was given, followed by close manipulation, and cast under image intensifier.[11] After achieving acceptable anatomical reduction, the forearm was immobilized with a below-the-elbow cast for 4 weeks. Following cast removal, the patient underwent supervised physiotherapy to prevent stiffness and was then followed-up at 3 and 6 months and yearly for anatomical and functional evaluation. The anatomical parameters were measured radiologically by determining the radial inclination, dorsal angulation or palmar tilt and radial bone length.[12] ([Fig. 1]) The MicroDicom software was used to calculate angles and lengths from the X-rays ([Fig. 2]).

The anatomical results were assessed as per criteria established by Stewart et al.[13] According to Stewart et al.,[13] acceptable dorsal angulation was 10 degrees, acceptable loss of radial inclination was 9 degrees, and acceptable loss of radial bone length was 6 mm ([Table 1]). The functional outcome was assessed with the Mayo wrist score measured at 6 months at the latest follow-up[14] ([Table 1]). A goniometer was used to measure the flexibility of the wrist joint of the healthy and the injured hand. A dynamometer was used to measure the grip strength.

The demographic data were measured with mean, range, and proportions. For com- paring anatomical and functional outcomes, we used the chi-squared test of association using 2 × 2 tables in which the fields with excellent and good results and the fields with fair and poor results were combined. A p-value < 0.001 was considered statistically significant. To examine strengths of associations, we computed odds ratios (ORs) with 95% confidence intervals (CIs) for the functional result in relation to the anatomic result.

Comparing the individual anatomical parameters with functional results, there was a statistically significant association (p < 0.001) between the dorsal angulation and the functional results (chi-squared = 11.75, degree of freedom [DF] =1, p = 0.0006, odds ratio [OR] =7.67, 95% CI, 2.18–26.92) with 10° or less of dorsal angulation as a borderline value ([Table 3]).
A statistically significant association (p < 0.001) was found between the loss of radial inclination and functional results (chi-squared = 11.77, DF = 1, p = 0.0006, OR = 7.67, 95% CI, 2.18–26.92), with 9° or less of loss of radial inclination as a borderline value ([Table 3]).
A non-statistically significant association (p > 0.001[0.01]) was found between the loss of radial height and functional results (chi-squared = 6.62, DF = 1, p = 0.01, OR = 4.57, 95% CI, 1.33–15.33), with 6 mm or less loss of radial height as a borderline value ([Table 3]).
For estimating the borderline value for loss of radial height, a statistically significant association was found with the functional result (chi squared = 11.70, DF = 1, p = 0.00062, OR = 8.94, 95% CI, 2.23–35.84), with 4 mm or less of loss of radial height from the mean as a borderline value ([Table 3]).

Discussion
The incidence of the Colles fracture was highest among the elderly in the 60 to 69 years age group (range 60–80). It was 3 times more common in women (42 [60%]) than men (28 [40%]). These findings were similar to those of Chung et al.,[15] in which 86.7% were women with a mean age of 70.9 ± 8.9 years.
The normal morphometry of the distal radius measured from the normal wrist were: radial inclination mean of 25.6 ± 2.8° (20–30°), palmar tilt of 7.9 ± 4.2° (0–15°), and radial bone length of 13.4 ± 1.7 mm (8–18 mm). The morphometric data may vary as per geographical locations and races ([Table 4]).[11] [16] [17] [18]

Comparing functional and anatomical results, the functional result was excellent or good in 55 (78.5%) and satisfactory or poor in 15 (21.5%) cases, whereas the anatomical results were excellent or good in 48 (68.5%) and satisfactory or poor in 22 (31.5%) elderly patients with Colles fracture treated non-operatively ([Table 5]). The statistical analysis showed a significant correlation between them, with p = 0.0009, chi-squared = 10.99, OR =7.17. This differs from the results obtained by Gartland and Werley, who obtained surprisingly good functional results despite poor repositioning and inadequate immobilization.[6] Our results also differ from those reported by Finsen et al.[10] and Chung et al.,[15] who reported that precise restoration of the wrist anatomy is not associated with better functional outcome.[10] [15] Arrora et al.[19] found that anatomic reconstruction did not convey any improvement in the range of motion or better ability in the daily activities of the elderly. Anzarut et al.[20] and Young & Rayan[21] also agreed that radiographic reduction was not associated with better functional outcome and obtained good function in cases in which the anatomical results were poor. However, few other authors reported a significant correlation between the anatomical and functional results, which agrees with this study, such as Kong et al.,[22] who determined that satisfactory reduction is the first choice, as malalignment leads to decreased grip strengths, unsatisfactory appearance, and certain limitation of wrist movements. Slogaard et al.[23] found that the function was influenced by radiographic results; thus, it would make sense to improve the function by better reduction technique of the fracture and prevention of secondary displacements. Jenkins et al.[24] found that final recovery of the grip strength was related to the inclination of the articulate surface of the healed radius both coronal and sagittal planes, and loss of radial length appears to become an important determinant of long-term pain.

Data of 166 patients analyzed with 2-phase multivariable regression models only 2 of the 84 correlation coefficients calculated were statistically significant; grip strength with radial inclination and MHQ ADL score with ulnar variance. |
They conclude that precise restoration of the wrist anatomy is not associated with better functional outcome. |

0ut of 96 patients 75 (78.1%) got acceptable reduction and 21 (21.9%) got poor reduction. A significant correlation was found between ulnar positive variance with grip strength (r = 0.35, p = 0.03) and dorsal angulation with wrist flexion (r = 0.31, p = 0.02) |
They concluded that satisfactory reduction is the first choice as malalignment leads to decreased grip strengths, unsatisfactory appearance and certain limitation of wrist movements. |

Reviewed 260 patients. Though there exist a statistically significant association between functional and anatomical results by Bivariate analysis however multiple regression showed dorsal angulation, ulnar variance and radial inclination accounts only 11% of variability. |
They concluded that final radiological alignment of distal radius fracture has minor influence on clinical outcome of Colles fracture. |

Mal-union and dysfunction-in Colles fracture |
Results of 61patients. The anatomical parameters at union were: mean dorsal angulation of 9° (SD 12.1), mean loss of radial inclination 7.8° (SD 7.2°) and mean radial shortening of 4 mm (SD 3.9 mm). Loss of grip strength and loss of flexion were taken as the functional parameter. A multilinear regression analysis showed statistically significant correlation between grip strength and loss of radial inclination and dorsal angulation and same with loss of flexion but did not reach level of significance. |
Final recovery of the grip strength was related to the inclination of the articulate surface of healed radius both coronal and sagittal plane. Loss of radial length appears to become important determinant of long-term pain. |
Garland and Werely (1951)[6] |
Evaluation of healed Colles fractures |
Good functional results (68.3%) achieved despite of poor radiological appearances. |
The residual dorsal tilt more strongly associated with poor outcome than the loss of radial inclination or radial height or ulnar variance. However Cases showing more accurate reduction have best outcome. |

Determining the borderline values of anatomical parameters for better functional outcome of Colles fracture. A prospective study |
Of 70 patients excellent to good functional results was seen in 55 (78.55) and anatomically in 48 (68.5%) with a statistically significant correlation between them p < 0.001(0.0009) |
Concludes anatomical reduction and maintaining the reduction is priority for better functional outcome. |
By studying the association of individual anatomical parameters with the functional results, the present study showed a significant association of dorsal angulation < 10° and loss of radial inclination of < 9° with functional results, (p = 0.0006, chi-squared = 11.75, OR = 7.67) but not with loss of radial height < 6 mm, (p = 0.01). Instead, when loss of radial length was kept to < 4 mm, statistical significance was achieved (p = 0.00062, chi- squared = 11.70, OR = 8.94). ([Table 6]) Stewart et al.,[13] in his work on functional cast bracing for Colles fracture, found that fractures with dorsal angulation < 10 degrees, loss of radial inclination of < 9 degrees and loss of radial height < 6 mm had better functional outcome, irrespective of the methods of immobilization of casting or bracing. Altimissi et al.[25] reported unsatisfactory results with dorsal angulation > 15 degrees, loss of radial inclination of < 5 degrees and ulnar variance > 5 mm. Slogaard et al.[23] found that functional results were excellent or good with dorsal angulation < 10° and loss of radial height < 7 mm. Salmon and Patrick et al.[26] defined malunion in distal radius fracture with dorsal angulation > 10 degrees, loss of radial inclination of < 17 degrees and loss of radial height > 3 mm and ulnar variance > 1 mm. Fuji et al.[27] reported radial shortening of more than 6 mm may result in poor functional outcome. Smilovic et al.[28] defined borderline values as dorsal angulation ≤ 9 degrees, loss of radial inclination of ≤ 3 degrees, and loss of radial height ≤ 2 mm for achieving good function.

< 10° |

Recommends anatomic reduction of the fracture with in the borderline limits of the individual parameters as mentioned for achieving excellent to good functional results. |
The limitation of this study is its small sample size (n = 70). It followed a bivariate analysis using the chi-Square test and OR for data analysis, as distal radius fracture is influenced by multiple variables apart from fracture reduction, so a multivariable regression model of analysis would have been a better choice for statistical analysis. Anatomic reduction may not always be the only parameter for better function, as indicated by Cooney et al.,[29] who pointed out that soft-tissue injury was equally responsible for the resulting stiffness. This was not considered in the present study, which may have been a limitation.
The strength of the present study is that only a few other studies, such as the one by Smilovic et al.,[28] have been conducted for measuring the borderline values of anatomical parameters needed for good function. Therefore, we believe that further research with larger sample sizes and higher statistical analytic models would confirm the values found in this study.
#
Conclusion
Until today, the non-operative management of Colles fracture, especially in elderly patients, has remained as an acceptable modality of treatment; however, good function can be achieved with better anatomical reduction. The present study recommends acceptable borderline values of anatomical parameters as dorsal angulation < 10°, loss of radial inclination < 9°, and loss of radial height < 4 mm to achieve excellent or good functional results.
