Evidence-Based Practice in the Surgical Treatment of Thumb Carpometacarpal Joint Arthritis.

ABSTRACT: Thumb carpometacarpal (CMC) arthritis contributes considerably to functional disability in the aging adult United States (US) population. Owing to the increasing growth in this segment of our population, its burden on health care resources will increase in the future. Variations exist in the degree of complexity and cost among different surgical treatments. We examined the national trends of the surgical treatment of thumb CMC arthritis and hypothesized that current practice patterns are not supported by evidence favoring the simpler trapeziectomy-only procedure.Using a random 5%, nationally representative, sample of Medicare fee-for-service beneficiaries diagnosed with thumb CMC arthritis between 2001 and 2010, we used a multinomial logistic regression model to assess the association between patients' characteristics and the surgical treatment. Furthermore, we used surgeons' unique identifiers to examine how their practice preferences have changed over time.Our findings demonstrated an increasing trend in the utilization of trapeziectomy with ligament reconstruction and tendon interposition (LRTI) from 84% in 2001 to 90% in 2010. Ninety-five percent of surgeons performed only 1 type of surgical procedure, and among those, 93% of surgeons performed only trapeziectomy with LRTI. Compared with 2001, the odds of a patient undergoing thumb CMC arthrodesis or prosthetic arthroplasty slightly increased between 2007 and 2010.The majority of hand surgeons in the US use trapeziectomy with LRTI as the surgical treatment of choice for thumb CMC arthritis. Although clinical trials from the United Kingdom support the use of the less complex trapeziectomy-only procedure, US surgeons are still reticent to change their practice, which favors LRTI. National comparative studies are still needed to examine the effectiveness of various surgical options for the treatment of thumb CMC joint arthritis.Prognostic II.

Project description:There are numerous techniques for the surgical management of thumb carpometacarpal (CMC) joint arthritis. The four senior authors of this study employ three such techniques: trapeziectomy with hematoma distraction arthroplasty, hemitrapeziectomy with osteochondral allograft, and ligament reconstruction tendon interposition (LRTI). This study examines the three commonly utilized procedures at a single institution. This study examines the 10-year experience from 1995-2005 with a minimum 3-month follow-up. Disabilities of the arm, shoulder, and hand (DASH) scores, pre-and postoperative pinch strength, and operative time were examined. After approval from the institutional review board of our institution was obtained, all patients treated surgically by three of the senior authors were contacted via mail and phone. Each patient was asked to complete and return a DASH questionnaire. Of the 115 patients treated during that period, 60 participated in this study. Each patient's final postoperative pinch measurement was obtained from occupational therapy and clinic records. This pinch strength was compared to the preoperative pinch and contralateral pinch strength. Lastly, the total operative time for each procedure was obtained from the operative record. The only significant finding in this study was a shorter mean operative time with the trapeziectomy group (76.90 min) and osteochondral allograft group (90.45 min) when compared to the LRTI group (139.00 min; p = 0.001 and p = 0.001, respectively). We found no significant difference between groups in terms of DASH score and pinch strength. There was no difference between the techniques in terms of postoperative pinch strength and patient satisfaction measured by DASH scores. The operative times for trapeziectomy and hematoma interposition as well as the osteochondral allograft were significantly shorter than that of the LRTI. This presents further evidence that potentially, "less is more" in the treatment of thumb CMC arthritis. We used a retrospective study design to evaluate potential differences between the three surgical techniques described above, therapeutic, levels III-IV.

Project description:BACKGROUND: The purpose of this study was to determine current practice patterns and examine the influence of recent evidence in the surgical treatment of advanced thumb carpometacarpal (CMC) osteoarthrosis. METHODS: A survey was sent to 2,536 American Society for Surgery of the Hand members. Information regarding specialty training, years of experience, annual cases performed, treatment of choice, technique, and postoperative immobilization was collected. Respondents were asked whether their current treatment of choice differs from what they performed 5 years ago and about the importance of ligament reconstruction and "interposition" to thumb CMC arthroplasty success. RESULTS: One thousand twenty-four respondents completed the survey (40% response rate). Treatment of choice was trapeziectomy with ligament reconstruction and tendon interposition (68%), regardless of specialty training, years of experience, and annual cases performed. Over 70% favored treatment that was not different from what they performed 5 years ago. Less than 3% of respondents perform a trapeziectomy alone; only 14 surgeons have changed to this procedure in the last 5 years. Only 35% of the 822 respondents who perform a ligament reconstruction and 14% of the 764 respondents who perform an interposition believe those techniques are "extremely important" to thumb CMC arthroplasty success. CONCLUSIONS: Despite recent evidence that suggests neither ligament reconstruction nor tendon interposition confers any additional benefit over trapeziectomy alone, few respondents have converted to the simpler procedure. Either the current evidence is not convincing enough to drastically change practice patterns, or other factors apart from this evidence have a greater influence on surgical decision-making for advanced thumb CMC osteoarthrosis.

Project description:Objective Contradictory reported arthritic patterns of the metacarpal surface of the trapezium include preferential volar wear, radial wear, and dorsal-ulnar sparing. We investigated whether a predominant wear pattern exists in surgical trapeziectomy for advanced thumb carpometacarpal (CMC) arthritis. Methods We examined 36 intact trapezia from 34 thumb CMC arthroplasty patients over an 18-month period. The first metacarpal articular surface revealed three consistent morphology patterns: (1) saddle, (2) dish, and (3) cirque. The saddle represented cartilage loss with preservation of the normal trapezial morphology. The dish shape represented concave curvature, with loss of the normal saddle configuration. The cirque shape represented preferential volar concave wear, disrupting the convex volardorsal arc. Two surgeons classified the randomized specimens twice, blinded to patient identity and each other's categorization. Radiographic Eaton staging was correlated retrospectively for 35 of 36 of the trapezial specimens. Eight specimens were further quantified with micro-computed tomography (micro-CT). Results Thirty-six trapezia were classified as follows: 17 (47%) saddle, 12 (33%) dish, and 7 (19%) cirque. Intra-rater reliability was 0.97 and 0.95; inter-rater reliability in the second round was 0.95. The 36 trapezia represented 27 female (75%) and 9 male (25%) patients; 18 (50%) represented the dominant hand. Age at surgery averaged 64 (33-76). Complete cartilage loss of the entire metacarpal surface was seen in 15 (42%) of all specimens. Osteophyte presence was typically minimal in the saddle group; the dish group had characteristic extensive rimming osteophytes in a 91% female population (11/12), and the cirque group had volar osteophytes. Radiographic severity ranged from Eaton stage II to IV; less severe radiographic staging (Eaton II) predominated in the saddle configuration; advanced Eaton III-IV disease predominated in both cirque and dish shapes. Micro-CT verified the three discrete shapes with volardorsal and radioulnar orientation measurements. Conclusion The metacarpal surface of the trapezium demonstrates three distinct patterns of wear in arthritic surgical specimens. Sex, dominance, age distribution, and Eaton stage varied across the different shapes. Level of Evidence Level 3 Study Type Observational.

Project description:BackgroundOsteoarthritis (OA) in the thumb carpometacarpal joint (CMCJ) is a prevalent disease which may lead to structural damage, severe pain and functional limitations. Evidence-based treatment recommendations state that all patients with hand OA should be offered non-pharmacological treatment. Surgery should be considered only when other treatment has proven insufficient in relieving pain. The purpose of this study was to investigate prior treatment and characteristics of patients referred to specialist health care surgical consultation due to CMCJ OA. The study includes exploring differences in pain and function between referred and non-referred hand, between men and women, and between patients with and without OA affection of other finger joints than CMCJ.MethodsPatients in this cross-sectional study reported prior non-pharmacological treatment for CMCJ OA. Patient demographics, disease and functional variables were assessed based on hand radiographs, patient-reported and observer-based outcome measures. Differences in pain and function between referred and non-referred hand, men and women, and between patients with and without additional affection of finger joints other than CMCJ, were analysed using Paired-samples T-tests, Wilcoxon Signed Rank, or Chi-Square tests.ResultsOne hundred and eighty patients were included. The mean age was 63 years and 79% were women. Only 21% reported having received non-pharmacological treatment before referral to surgical consultation. The results show a statistically significant worse function for referred hands, women and involvement of additional interphalangeal joints. Most patients reported no pain or mild pain in their referred hand.ConclusionsThe results of this study show a non-pharmacological treatment gap in OA care. Most patients report no pain or mild pain, and that they had not received non-pharmacological treatment prior to being referred to CMCJ OA surgical consultation. The results furthermore show that CMCJ OA negatively affects all aspects of function. Strategies need to be developed to improve OA care, including educating general practitioners in evidence-based treatment recommendations and in the assessment of hand pain, and encourage the routine referral of patients with symptomatic hand OA to occupational therapy before considering surgery.
