TRATAMENTO CIRÚRGICO DE RIZARTROSE: UMA REVISÃO SISTEMÁTICA DOS ÚLTIMOS DEZ ANOS

ABSTRACT

Introduction

Comparison of different surgical techniques to treat patients with rhizarthrosis or carpometacarpal osteoarthritis of the thumb.

Materials and Methods

A systematic review was conducted using three electronic databases. Randomized, controlled trials in patients who underwent surgery for the treatment of rhizarthrosis were included. The literature review followed the PRISMA protocol.

Results

A total of 15 articles involving a total population of 958 patients were selected. Seven different surgical techniques were compared.

Conclusions

We conclude that no procedure is superior to another in terms of pain, physical function, overall patient assessment, range of motion, or strength. Outcome measurements should be standardized to enable better comparison between surgical techniques. Level of evidence II, Systematic Review.

INTRODUCTION

Rhizarthrosis or thumb carpometacarpal osteoarthritis (CMC OA) is a common condition of pain and functional limitation in the hand. CMC OA affects 66% of women older than 55 years¹ and an estimated 22% of the general population aged 50 years and over are symptomatic²

Typically, patients have pain in the base of the thumb and with the progression of the disease: atrophy of thenar muscles, subluxation of the first carpometacarpal joint, loss of pinch and grip strength.

Eaton et al.³ describes 4 stages of thumb joint OA, based on radiological criteria with the end stage involving CMC and scaphotrapeziotrapezoid (STT) joints. In the early stages, patients can be treated with splinting of the thumb, along with anti-inflammatory drugs, steroid injections, and thumb-strengthening exercise⁴.

Orthosis may reduce pain, however it does not improve function, dexterity and strength⁵.

For those who fail nonsurgical treatment, surgery must be considered. Several surgical techniques have been performed, and include: trapezial excision with or without ligament reconstruction and tendon interposition (LRTI), arthroscopy and debridement, arthroplasty, trapeziometacarpal arthrodesis (TMA)⁶.

In 2010, Vermeulen et al⁷ published a systematic review including 35 articles, 9 of which not included in previous reviews.

This study aimed to conduct a systematic review of randomized controlled studies on different kinds of surgical treatment in rhizarthrosis from the last 10 years.

MATERIALS AND METHODS

This review followed the PRISMA protocol⁸. The search was carried out in the PUBMED, EMBASE, and Cochrane databases using the following terms (PICOS method): Patient: rhizarthrosis (Eaton stages II-IV) ; Intervention: Surgery; Comparison: Different kinds of surgical treatment; Outcomes: Pain, function, grip and pinch strength; Study design: randomised controlled trials.

The review was conducted in October 2019 and repeated in April 2020, and included studies from the last ten years (between 2011 to 2019) (Figure 1). Search terms included “rhizarthrosis”, “thumb carpometacarpal joint” and “ thumb osteoarthritis”. There was no restriction on publication language. First of all, a list was created with the titles and abstracts of studies potentially relevant and two independent reviewers (R.L.C.S and B.A.S.V.) applied the search. If the abstract suggested inclusion in our study, the full manuscript was retrieved and reviewed. Conflicts could be solved by a third researcher, however it was not necessary.

The same two reviewers, in an independent manner, extracted the data, which included: participants, intervention, comparison between techniques, scores, results and conclusion.

RESULTS

A total of 29 articles contained titles and abstracts relevant to the study and were selected for a complete reading of the text. After this stage, 15 articles were included, of which 958 patients were selected.

Five studies compared different techniques of trapezial excision with ligament reconstruction and tendon interposition (LRTI). Esenwein et al. (2011)⁹, compared T + LRTI using abductor pollicis longus (APL) or flexor carpi radialis (FCR). Similar results can be obtained using the technically less demanding APL-procedure when compared with the FCR-technique 8 months postoperatively. Vermeulen et al. (2014)¹⁰, compared T + LRTI (FCR) with or without bone tunnel, and obtained faster recovery in tunnel group, however, 12 months after surgery, the functional outcome was similar. Spekreijse et al.¹¹ (2015), comparing T + LRTI(FCR) with or without bone tunnel, showed that improved function, strength, and satisfaction obtained at 1 year after, was maintained after 5 years. Zajonc et al.¹² (2016), in 38 patients, compared T +LRTI (APL) from Lundborg and Sirotakova techniques. Both resection-suspension arthroplasty procedures led to a statistically significant postoperative reduction of pain, a significant improvement in radial and palmar abduction, a significant gain in quality of life and significant asymptomatic proximalization of the first metacarpal bone. Nanno et al.13 (2019), compared T +LRTI (APL) original and modified. There were no statistically significant differences in the thumb palmar abduction angle, pinch power, grip strength, Quick DASH score, or VAS score between groups. Patients in group 2 had a significantly better range of motion of radial abduction.

Three studies compared trapeziectomy versus trapeziectomy with or without LRTI. Salem et al.¹⁴ (2011) and Gangopadhyay et al.¹⁵ (٢٠١٢), studying ١١٤ and ١٥٣ patients, respectively showed similar objective and subjective outcomes between groups, so there appears to be no benefit to tendon interposition or ligament reconstruction in the longer term, furthermore Corain et al.¹⁶ (2016), demonstrated that the trapezium excision and bone space distraction technique requires a smaller incision, a shorter surgical time, an easier surgical technique, and a less painful recovery, maintaining overlapping levels of functional restore.

Other three studies compared trapezial excision with or without LRTI versus trapeziometacarpal arthrodesis (TMA). The first study by Vermeulen et al.¹⁷ was published in 2014. This study in 38 patients showed similar results in DASH and PRWHE scores twelve months after surgery, however fewer moderate and severe complications were related after trapeziectomy with ligament reconstruction and tendon interposition. A second study was published by Hippensteel et al.¹⁸ in 2017, comparing 52 patients. There were no significant differences in the amount of change in grip or pinch strength, patient-reported outcomes, or functional hand testing between groups. The incidence of complications was similar between operative groups, but revision surgery was more common after TMA. The third study from Li et al.¹⁹ published in 2019, in 39 patients, showed that arthrodesis displayed better pinch strength, while arthroplasty displayed better motor function. Patients were satisfied with the effects of both techniques.

One study compared arthroplasty versus trapeziectomy and LRTI (Thorkildsen et al. 2019)²⁰, in 40 patients. The results in the early rehabilitation were significantly better in the joint replacement group, as well as the range of motion in abduction and extension was better at the final follow-up. Patient satisfaction was high in both groups despite more complications after joint replacement. Trapeziectomy with ligament reconstruction and tendon interposition proved to be a safe and effective treatment with few complications in this trial.

Another study compared arthroplasty cemented and uncemented (Hansen et al. 2013)²¹, with 16 patients in each group, showing similar good results between groups at all measurement points in grip strength, pain and DASH score.

Another one study compared trapezial excision versus trapezial denervation. Salibi et al.²² (2019), in 45 patients, associated trapezial denervation with fast recovery, by the other hand 30% of these patients needed a reoperation.

The last study compared trapezial excision with LRTI versus trapezial excision and allograft. This study from Marks et al.²³, published in 2017, comparing 60 patients, showed similar outcomes, with more complications in the second group. Allograft was used only in cases of severe instability.

The DASH (The Disabilities of the Arm, Shoulder and Hand) score was the most frequently used (9 articles), followed by VAS (Visual Analogue Scale) (8 articles). (Figure 2).

The rhizarthrosis stage was classified according to Eaton in 12 articles. Three studies did not define the classification.

DISCUSSION

The aim of the study was to provide an updated review of the current literature (last 10 years), according to most used surgical procedures. We did not perform a statistical analysis because of the great heterogeneity between the included articles. Our search strategy identified 15 articles, none of them includes in previous systematic reviews.

First, we reviewed five studies comparing different techniques of trapeziectomy with ligament reconstruction and tendon interposition. No evidence of superiority between techniques was demonstrated.

The second group of studies, compared trapeziectomy alone and trapeziectomy with or without LRTI. Similar objective and subjective outcomes were obtained between groups, moreover trapezium excision isolated requires a smaller incision, a shorter surgical time, an easier and a less painful recovery.

The third group, including three studies, compared trapezial excision with or without LRTI versus trapeziometacarpal arthrodesis (TMA). Complications and repeat surgeries are more frequent following TMA compared to trapeziectomy with or without LRTI. One author suggested that arthrodesis displayed better pinch strength, while arthroplasty displayed better motor function.

When evaluating the study on arthroplasty versus trapezial excision with LRTI, we conclude that the results in the early rehabilitation were significantly better in the joint replacement group, as well as the range of motion in the final follow-up, by the other hand more complications were associated to the joint replacement group.

The study comparing cemented and uncemented arthroplasty, showed similar good results with both techniques.

Another study compared trapezial excision versus trapezial denervation and concluded that 30% of patients undergone trapezial denervation, needed a second surgical procedure.

Finally, an article comparing trapezial excision with LRTI versus trapezial excision and allograft, conclude that allograft should be used only in cases of severe instability, due to associated complications with the technique (Tables 1 and 2).

Studies conclusions.

Authors	Study	Nº of patients per group	Procedure	Author's conclusion
Hippensteel et al.6 (2017)	RCT	27	CMC arthrodesis	There were no significant differences in the amount of change in grip or pinch strength, patient-reported outcomes, or functional hand testing between TMA and LRTI. The TMA group had significantly increased thumb tip opposition distance. The TMA group was complicated by a 26% overall nonunion rate of which 8% were symptomatic. The LRTI group (Wagner incision) had a significantly increased incidence of superficial branch of the radial nerve paresthesia. The incidence of complications was similar between operative groups, but revision surgery was more common after TMA.
		25	LRTI
Esenwein et al. 9 (2011)	RCT	30	T + LRTI(APL)	Similar results can be obtained using the technically less demanding APL-procedure when compared with the FCR-technique 8 months postoperatively.
		25	T+LRTI (FCR)
Vermeulen et al.10 (2014)	RCT	36	T+ LRTI(FCR) with tunnel	After the bone tunnel technique, patients have better function and less pain 3 months after surgery than do those in the nonebone tunnel group, which indicates faster recovery. However, 12 months after surgery, the functional outcome was similar.
		36	T +LRTI (FCR) without tunnel
Spekreijse et al.11 (2015)	RCT	36	T+ LRTI(FCR) with tunnel	This study showed that improved function, strength, and satisfaction obtained at 1 year after trapeziectomy with LRTI with or without the use of a bone tunnel for stage IV TMC thumb osteoarthritis was maintained after 5 years.
		36	T +LRTI (FCR) without tunnel
Zajonc et al. 12 (2016)	RCT	19	T + LRTI(APL) Lundborg	Both resection-suspension arthroplasty procedures led to a statiscally signifcant postoperative reducion of pain, a significant improvement in radial and palmar abduction, a significant gain in quality of life and signifcant assymptomatic proximalisation of the first metacarpal bone. There was no signifcant difference in postoperative strength.
		19	T + LRTI(APL) Sirotakova
Nanno et al.13 (2019)	RCT	10	T +LRTI (APL original)	There were no statiscally significant differences in the thumb palmar abduction angle, pinch power, grip strength, Quick DASH score, or VAS score between groups. Patients in group 2 had a significantly better range of motion of radial abduction.
		20	T+LRTI(APL modif)
Salem et al.14 (2011)	RCT	59	T	There were no significant differences between the two treatments in any subjective or objective outcome measure at 6-year follow-up Eighty-two percent of the thumbs were painless or only ached after use. The DASH and Patient Evaluation Measure scores were significantly better than preoperatively.
		55	T+LRTI (FCR)
Gangopadhyay et al. 15 (2012)	RCT	53	T	The outcomes of these 3 variations of trapeziectomy were similar after a minimum follow-up of 5 years. There appears to be no benefit to tendon interposition or ligament reconstruction in the longer term
		46	T + TI (PL)
		54	T +LRTI (FCR)
Corain et al.16 (2016)	RCT	64	T + TI (APL)	We demonstrate that the trapezium excision and bone space distraction technique require a smaller incision, a shorter surgical time, an easier surgical technique, and a less painful recovery, maintaining overlapping levels of functional restore.
		56	T + hematoma and distraction
Vermeulen et al.17 (2014)	RCT	21	T + LRTI (FCR)	Women who are forty years or older with trapeziometacarpal osteoarthritis have fewer moderate and severe complications after trapeziectomy with ligament reconstruction and tendon interposition and are more likely to consider the surgery again under the same circumstances than are those who undergo arthrodesis. Twelve months after surgery, the PRWHE and DASH scores were similar in both groups. We do not recommend routine use of arthrodesis with plate and screws in the treatment of women who are forty years or older with stage-II or III trapeziometacarpal osteoarthritis.
		17	Arthrodesis
Li et al.18 (2019)	RCT	22	Arthrodesis	In Chinese patients, both techniques relieved pain and improve grip strength. Arthrodesis displayed better pinch strength, while arthroplasty displayed better motor function. Patients were satisfied with the effects of both techniques.
		17	T + LRTI (FCR)
Thorkildsen et al.19 (2019)	RCT	20	T + LRTI	Significantly better function in the joint replacement group in the early rehabilitation period as shown by the secondary outcome measures, Kapandji score and strength of key and tip pinch. In addition, the range of motion in abduction and extension was better at the final follow-up. Patient satisfaction was high in both groups despite more complications after joint replacement. Trapeziectomy with LRTI proved to be a safe and effective treatment with few complications in this trial.
		20	uncemented prostheses
Hansen et al.20 (2013)	RCT	16	cemented prostheses	Grip strength, pain, and DASH scores were similar between groups at all measurement points. Early implant fixation and clinical outcome were equally good with both cup designs.
		16	uncemented prostheses
Salibi et al.21 (2019)	RCT	19	Trapeziectomy	There was no difference between the two treatments. First CMCJ denervation does not appear to be superior to trapeziectomy. However, the advantage of rapid rehabilitation makes it more favored by patients but at the expense of 30% reoperation rate.
		26	Trapezial denervation
Marks et al.22 (2017)	RCT	29	T +LRTI (FCR)	The use of the FCR tendon or allograft for trapeziectomy with suspension interposition arthroplasty in patients with CMC I OA leads to similar outcomes with more complications, mainly tendon irritations, associated with the latter. Allograft was used only in cases of severe instability requiring a larger amount of suspension-interposition material or for revision procedures after failed suspension-interposition with the FCR tendon.

CONCLUSION

We conclude that no procedure is superior to another in terms of pain, physical function, patient global assessment, range of motion, or strength. Furthermore, because differences between the various techniques are small, researchers should focus on developing more sensitive outcome measures that are indicative of the specific changes in hand function after CMC OA. We suggest that outcomes measures be standardized. The Disabilities of the Arm, Shoulder and Hand (DASH) perhaps the most indicated like a Patient Report Outcomes (PRO), in association with Visual Analogue Scale (VAS), grip and pinch strengths.
