Abstract

Purpose Although indications for four-corner arthrodesis (4CA) and proximal row carpectomy (PRC) are not completely aligned, the surgeon is often tasked with deciding between these options which vary in the surgical technique and complication profile. Patient age is often discussed as a determining factor for treatment; however, outcome data for these procedures are rarely stratified by patient age. Our objective was to perform a systematic review on the age-specific outcomes for 4CA and PRC.

Materials and Methods A PubMed database search for 4CA and PRC was performed according to Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. The inclusion criteria required individual case reporting of patient age, surgical intervention, and appropriate outcome measures. The data were stratified by procedure and by patients older and younger than 45 years.

Results Within the 4CA group, the relative risk for a disabilities of the arm, shoulder, and hand (DASH) score above 30 was 1.94 (95% confidence interval, 1.1–3.67) in patients over 45 years compared with patients under 45 years. Within the PRC group, grip strength as a percentage of the contralateral side was higher in the over 45 age group (mean 75%) compared to the under 45 age group (mean 61%) but did not reach the level of significance.

Conclusion Despite satisfactory results for 4CA in aggregate, the distribution of scores indicates the need for setting expectations when treating younger adult patients with 4CA. The current results demonstrate increased disability based on DASH score following 4CA in patients under 45 years compared with patients over 45 years. Although outcomes were comparable between younger and older adults following PRC, recovery of grip strength may occur less frequently in younger adults.

Level of evidence IV systematic review.

Proximal row carpectomy (PRC) and four-corner arthrodesis (4CA) are considered motion-sparing procedures for various etiologies of wrist arthritis. Although indications for each are not completely aligned, the surgeon is often tasked with deciding between these options which vary in the surgical technique and complication profile. Aggregate reporting has identified nonunion as a common complication following 4CA[1] [2] [3] [4] and limitations in grip strength complicate PRC due to an altered length–tension relationship of the flexors.[1] [5] [6]

Patient age continues to be a conundrum in determining the most appropriate treatment in cases of wrist arthritis. Although patient age is often discussed as a determining factor between 4CA and PRC, results are infrequently stratified by age. Wagner et al[6] reported similar outcomes between 4CA and PRC for a series of patients aged 45 years and under. DiDonna et al[7] concluded that PRC patients under 35 years had a significantly increased risk of radiocapitate pathology which may translate into worsening clinical outcomes. Whether these findings are representative of the aggregate literature is unknown.

Previous systematic reviews reporting outcomes for 4CA and PRC provided datasets with a mean patient age between 45 and 50 years but the age ranges are widely distributed.[2] [4] [8] [9] [10] [11] Physiologic aspects of healing and recovery are not uniform across a large age distribution. Thus, treatment decisions should be evaluated within the confines of a more narrow age bracket to provide a template for informed clinical decision-making.

Our objective was to perform a systematic review on the age-specific clinical outcomes for PRC and 4CA. These data intended to determine whether outcomes differed between younger and older age groups and whether 4CA or PCR yielded superior outcomes between these age groups.

Materials and Methods

Search Strategy

A PubMed database search was performed on October 05, 2023 according to the Preferred Reporting Items for Systematic Reviews and Meta-analysis guidelines. The following search terms were used: “proximal row carpectomy,” “four corner arthrodesis,” “four corner fusion,” “4 corner arthrodesis,” “4 corner fusion,” “scaphoid nonunion advanced collapse,” and “scapholunate advanced collapse.”


#

Eligibility Criteria

The population, intervention, comparison, and outcome characteristics for eligibility were the following:

  • P—adults over the age of 18 years.

  • I—treated with PRC and 4CA for all indications.

  • C—clinical outcomes between these interventions were compared.

  • O—age groups were delineated for outcome comparison.

The inclusion criteria required individual case reporting of patient age, surgical intervention, and appropriate outcome measures.[12] Three or more cases per report were required for inclusion.


#

Data Collection

The following case data were extracted from each included article: patient age, patient gender, indication for surgical intervention, follow-up term, visual analog score for pain, disabilities of the arm, shoulder, and hand (DASH) score, grip strength expressed as a percentage of the contralateral side, wrist arc of motion, nonunion, hardware removal for 4CA cases, radiographic radiocapitate narrowing for PRC cases, and revision surgery. For outcomes without standardized parameters, a reasonable interpretation of the provided verbiage was made to ensure continuity in aggregation. The lack of revision or removal surgery was not presumed due to the absence of verbiage stating the presence of these secondary procedures. When radiocapitate narrowing was reported using specified criteria, the data were aggregated using a binary protocol of present for moderate/severe arthrosis or partial/complete narrowing and absent for none/minimal.


#

Data Grouping

The data were stratified by procedure and by patients older than and younger than 45 years. The age of 45 years was chosen to maintain consistency with the prior work by Wagner et al[6] which compared results between 4CA and PRC in patients under 45 years. Although the Wagner et al article did not provide individual case reporting, it was included in aggregate analysis due to the entirety of the series aligning with the under 45 years age group.


#

Data Analysis

Clinical outcomes were compiled as means and then compared between groups using the two-sample t-test and Fisher's exact test. Due to disparate sample sizes, some data were presented with and without the Wagner et al[6] article. For DASH scores, results were stratified as scores above and below 30. This score was chosen based on the approximate mean for previous reviews on 4CA and PRC.[1] [4] [8] [9] The Wagner et al[6] article was not included in this analysis due to a lack of individual case scores.


#

Risk of Bias

The Cochrane ROBINS-I (risk of bias in non-randomized studies of interventions) provides the following domains for evaluation: confounding, selection of participants, classification of interventions, deviation from intended interventions, missing data, measurement of outcomes, and selection of reported results.[13] For all included studies, each domain was graded as low, moderate, or severe risk, and then, a final grade was given which corresponded to the highest level of risk across the domains.


#

Quality Assessment

The GRADE (Grading of Recommendations, Assessment, Development, and Evaluation) framework provided the following factors for the evaluation of research quality: limitations, inconsistency, indirectness, imprecision, and publication bias.[14] A binary scale for serious limitations was used for each factor across the outcomes of interest.

Search Results

Following irrelevant exclusions, 132 articles were screened by full text ([Fig. 1]). Of those, 55 were excluded due to a lack of individual case reporting. Twenty-five articles met the inclusion criteria with 207 cases in the 4CA group (mean follow-up 50 ± 67 months) and 171 cases in the PRC group (mean follow-up 79 ± 64 months; [Table 1]).

Discussion

Although the mean DASH scores following 4CA are comparable between patients under and over 45 years, the distribution of scores is conspicuous. The current results demonstrate an increased risk of disability based on DASH score following 4CA in patients under 45 years compared to patients over 45 years. There was a nearly twofold increase in risk of a DASH score above 30 in the younger adult group following 4CA. This finding indicates an increased risk of continued pain and dysfunction in adults under 45 years who are treated with 4CA compared with adults over 45 years.

Following PRC, patients over 45 years had greater recovery of grip strength compared with patients under 45 years. This may be explained by a general decline in strength with advancing age. Thus, the loss of strength may be more impactful and demonstrable in younger adults. Grip strength is a commonly reported clinical outcome following the treatment of wrist arthritis. Results between 4CA and PRC are conflicting across the literature with reasonable postulates for both procedures yielding superiority of grip strength. Laronde et al[16] reported superior grip strength in PRC compared with 4CA despite a significant loss in carpal height in the PRC group. The review by Saltzman et al[1] found significantly superior grip strength following 4CA compared with PRC. Conversely, the review by Amer et al[3] reported significantly greater grip strength in PRC patients compared with 4CA patients. The lack of uniformity between results for grip strength following 4CA and PRC may be explained by the findings of Nichols et al[5] which described alterations in muscle moment arms following both procedures. PRC yielded a flexion bias and 4CA, a radial deviation bias. With the understanding that grip strength may be optimized in wrist extension and ulnar deviation, the planar changes in muscle moment arms may explain why reduced grip strength may follow both procedures.

Following PRC, pathological changes to the radiocapitate joint may be due to nonanatomic loading patterns and a mismatched radius of curvature between the capitate and lunate fossa. The PRC review by Chim and Moran[11] determined that a high rate of radiographic radiocapitate arthrosis did not yield clinically impactful findings at more than 10 years of follow-up. This finding is consistent with Wagner et al[17] who reported 45% of moderate-to-severe radiocapitate arthrosis following PRC at a mean follow-up of 13 years. Using four-dimensional scanning in PRC patients at a mean follow-up of 7.3 years, Peymani et al[18] described increased radiocapitate contact area and capitate remodeling. This is indicative of the adaptive response which contributes to favorable outcomes despite a nonanatomic result of PRC. Although the current findings show comparable rates of advanced radiocapitate pathology between younger and older adults following PRC, continued monitoring in younger adults may be advised.

Prior reports have identified patient age as an important consideration for treatment decisions involving 4CA and PRC. Wagner et al[6] provided one of the few reports for the performance of 4CA and PRC in younger adults. Their series spanned a spectrum of disease severity and indications, with few exclusions. At a mean follow-up of 11 years for the 4CA group and 18 years for the PRC group, there were similar rates of radiographic arthrosis in both groups, and motion trended toward superior for the PRC group. Further, the same group provided a narrative review of 4CA and PRC in young patients which highlighted the lack of definitive data in support of either of these procedures.[19] Traverso et al[20] reported high patient satisfaction and function at more than 10 years follow-up and noted the durability of 4CA in younger adults as 33% of the series were aged 45 years or under at the time of the index procedure. Despite 27% of 4CA cases having advanced radiolunate space narrowing, the authors reported a mean DASH of 7.8, revision to wrist fusion of 6.7%, and zero cases of nonunion. The current findings indicate an increased risk of revision in younger adults compared with older adults following 4CA.

Important considerations have been identified to guide surgeons when evaluating 4CA and PRC in younger adults. The review by the Wagner group noted that clinical satisfaction following 4CA may be predicated on bony union.[19] Thus, activities such as smoking which increases the risk of nonunion must be considered.[21] Additionally, job or lifestyle activities which require a greater range of motion may indicate a preference for the motion preservation of PRC. However, motion discrepancies between PRC and 4CA may not be as functionally evident in younger adults due to adaptive capacity. It is reasonable to anticipate if not expect adaptations in adjacent joints to yield improved function over time. Further, the concern for radiocapitate arthrosis following PRC is certainly more warranted in younger adults. In totality, the surgeon must evaluate patient specifics including age and have a complete understanding of the mechanics involved in 4CA and PRC when indicating these procedures.

We acknowledge existent limitations, primarily those that are inherent to amalgamating the work of others. Errors and biases from the included studies weaken the current work. Further, when aggregating clinical outcomes, there is the potential for reporting and interpretation errors. DASH and QuickDASH differ in the number of questions which can impact the absolute value of the score. These metrices are often reported interchangeably which can confound aggregate reporting. Additionally, there was heterogeneity in the verbiage used to report radiocapitate narrowing. The included studies infrequently identified the specific cases which required revision; thus, the current findings for revision should be interpreted as incomplete. However, the noted trend of increased revision in younger adults following 4CA is consistent with prior literature and supported by a reasonable sample of cases. The current data were compiled for all indications which may hinder a more focused conclusion for each procedure. Although the applied inclusion criteria using individual case data reduced the available sample of literature, this methodology allowed age stratification and yielded 50 or more cases in each age group which is a robust sampling for these procedures.


#

Conclusion

In aggregate, clinical outcomes at short-to-midterms of follow-up are comparable between 4CA and PRC. However, stratification of cases into age groups displays trends that may be clinically relevant. PRC in patients over 45 years demonstrated significantly greater grip strength recovery compared with patients under 45 years. Further, there is an increased risk of disability based on the DASH score when treating patients under 45 years with 4CA. This indicates the need for setting expectations prior to 4CA in younger adults.
