Surgical treatment of carpometacarpal thumb arthritis with trapeziectomy and intra-tendon (FCR) suspension with one-loop APL: comparative cohort study.

BACKGROUND: One of the current choices of treatment for Trapeziometacarpal (TMC) joint arthritis is trapeziectomy with ligament reconstruction and tendon interposition arthroplasty. The Ceruso's technique consists of complete trapezial excision and abductor pollicis longus (APL) tendon suspension. The APL tendon is tied to the flexor carpi radialis (FCR) tendon with two loops, one around it and one inside, and then used as interposition tissue. The purpose of the present study was to compare two different techniques of a trapeziectomy with ligament reconstruction and tendon interposition arthroplasty using the Abductor Pollicis Longus (APL) tendon, which is only Once Looped Around (OLA) versus Once Looped Inside (OLI) the Flexor Carpi Radialis (FCR) tendon. METHODS: A single-center, retrospective study (Level of evidence: III) has been conducted on sixty-seven patients older than 55 years (33 OLI, 35 OLA), assessing clinical outcomes for at least 2 years of post-surgery follow-up. The outcomes were to assess and compare surgical outcomes comparing the two groups, in terms of subjective and objective evaluation for both groups at the last follow-up (primary outcome), and at the intermediate follow-ups (three and six months). Complications were also assessed. RESULTS: The authors found an improvement in pain, range of motion, and function, with equivalent results for both techniques. No subsidence was observed. FCR tendinitis was significantly reduced with OLI, as well as the need of post-operative physiotherapy. CONCLUSIONS: The one-loop technique allows for reduced surgical exposure, providing excellent suspension and clinical outcomes. Intra FCR loop should be preferred to improve post-surgical recovery. LEVEL OF EVIDENCE: Level III study. This is a retrospective cohort study (written according to STROBE guidelines).

The Effect of Thumb Metacarpophalangeal Hyperextension on Thumb Axial Load and Lateral Pinch Force in a Cadaver Model of Thumb Trapeziectomy and Flexor Carpi Radialis Suspensionplasty.

PURPOSE: The purpose of our study was to investigate, in a cadaver model, the effect of increasing thumb metacarpophalangeal (MCP) joint hyperextension on thumb axial load and key pinch force after thumb trapeziectomy and flexor carpi radialis suspensionplasty. We developed a cadaveric model to test whether thumb MCP joint hyperextension after trapeziectomy would have a negative effect on key pinch force and increase loads across a reconstructed thumb carpometacarpal (CMC) joint. METHODS: We created a cadaveric biomechanical model that varied thumb MCP joint hyperextension while measuring thumb CMC axial and key pinch force under standardized loads. Direct observations were made of how key pinch and axial thumb CMC force change with increasing thumb MCP joint hyperextension. We measured the thumb key pinch force and axial thumb CMC joint load with the thumb MCP joint in 0°, 10°, 20°, 30°, 40°, 50°, and 60° of hyperextension. RESULTS: There was a 0.88 N (2.4%) increase in axial force across the thumb CMC per every 10° of increasing thumb MCP joint hyperextension. We found a 0.53 N (4.4%) reduction in key pinch force for every 10° of increasing thumb MCP joint hyperextension. Therefore, at 60° of thumb MCP joint hyperextension, the axial force across the thumb CMC increased by 5.3 N (14.6%) and the key pinch force was weakened by 3.2 N (26.6%). CONCLUSIONS: With progressive thumb MCP joint hyperextension after thumb CMC arthroplasty, we found a decrease in key pinch force and an increase in axial thumb CMC joint force. The decrease in key pinch force was larger than the relatively small increase in thumb CMC force. CLINICAL RELEVANCE: This study helps elucidate the biomechanics of the thumb CMC joint after resection arthroplasty with thumb MCP joint hyperextension and helps understand the interplay between these 2 conditions.

Is Hand Therapy Associated With a Delay in Surgical Treatment in Thumb Carpometacarpal Arthritis?

PURPOSE: Thumb carpometacarpal (CMC) osteoarthritis (OA) causes functional disability and an increased health care burden in the aging population. The role of therapy in thumb CMC OA has been minimally analyzed in the literature. We hypothesized that patients treated with therapy for thumb CMC OA would demonstrate reduced rates of surgery for this diagnosis. METHODS: We queried a national insurance dataset for all patients with an International Classification of Diseases, Ninth Revision, or International Statistical Classification of Diseases, Tenth Revision, code for thumb CMC OA, with a minimum of 2 years of follow-up. A 2:1 propensity-matched cohort of patients with CMC OA who did not receive therapy versus a therapy cohort was created, with a minimum of two sessions of hand therapy for inclusion. The primary outcome was the rate of thumb CMC OA surgery occurring within 2 years of diagnosis; time to surgery and use of thumb CMC injections were secondary outcomes. Multivariable logistic regression analysis was used to identify the risk factors for undergoing surgical treatment. RESULTS: After matching, the therapy cohort comprised 14,548 patients, with a matched group of 28,930 patients who did not undergo therapy. In the overall sample, the rate of surgery within 2 years was 22.5%. Two-year surgical treatment rates were significantly higher for those who did not undergo therapy when compared with those who did (29.3% vs 13.1%). Patients treated with therapy had a significantly longer time to surgery, with no difference in the rate of surgery after one year. In multivariable regression of all included variables, lack of therapy intervention had the highest odds of surgery for thumb CMC OA (odds ratio 4.3). CONCLUSIONS: We present the findings of a large insurance database evaluating the association of therapy with rates of surgical treatment for thumb CMC arthritis. On average, those treated with therapy had longer times to surgery, and the 2-year surgery rates for patients diagnosed with thumb CMC arthritis were significantly higher in those who did not undergo therapy treatment. TYPE OF STUDY/LEVEL OF EVIDENCE: Prognostic II.

Effect of a stabilization exercise program versus standard treatment for thumb carpometacarpal osteoarthritis: A randomized trial.

STUDY DESIGN: Randomized, interventional trial with 1 year follow-up. INTRODUCTION: Though recommended, evidence is lacking to support specific exercises to stabilize and strengthen the first carpometacarpal (CMC) joint for cases of osteoarthritis (OA). PURPOSE OF THE STUDY: To determine in a naturalistic setting, whether standard treatment plus a home exercise program (ST+HEP) is more effective than standard treatment (ST) alone in improving Quick Disabilities of Arm, Shoulder and Hand (qDASH) scores, and secondarily, in other patient-centered (pain, function) and clinical outcomes (range of motion, strength). METHODS: A total of 190 patients from a hand therapy practice in northwestern PA were enrolled by informed consent and randomized into ST or ST+HEP groups. Average age was 60 years, most were female (78%) with sedentary occupations most common (36%). ST group received orthotic interventions, modalities, joint protection education and adaptive equipment recommendations, while the ST+HEP group received a home exercise program in addition to ST for 6-12 months. Follow-up occurred at 3, 6, and 12 months. Outcomes included grip strength, pinch strength, range of motion (ROM), qDASH, Patient Specific Functional Scale (PSFS) and pain ratings. At the 6 month mark, all subjects could change groups if desired. Efficacy data analysis included both parametric and non-parametric tests. The threshold for statistical significance was 0.05 and adjusted for multiple comparisons. RESULTS: Repeated measures ANOVA failed to show a statistically significant difference in strength and ROM assessments between treatment groups over the 12 month follow-up (P ≥ .398). Differences between groups did not exceed 13%. Both the ST and ST+HEP groups evidenced improvement over time in most patient-focused assessments (P ≤ .011), including improvements exceeding reported clinically important differences in pain with activity and PSFS scores. Scores for these measures were similar at each follow-up period (P ≥ .080) in each group. The presence of CTS exerted no effect on outcomes; longer treatment time was weakly related to poorer qDASH and PSFS scores initially. Of those enrolled, 48% of subjects completed the study. CONCLUSIONS: The addition of a high-frequency home exercise program did not improve clinical or patient-centered outcomes more so than standard care in our sample however, study limitations are numerous. Both groups had decreased pain with activity and improved PSFS scores, meeting the established minimally clinically important difference (MCID) of each at 6 and 12 months. Adherence with the home program was poor and/or unknown.

Biomechanical Analysis of Abductor Pollicis Longus Lasso Suspensionplasty for Trapeziectomy.

PURPOSE: Multiple methods of ligament reconstruction and tendon interposition (LRTI) or suspension have been described to prevent first metacarpal subsidence following trapeziectomy. An abductor pollicis longus (APL) lasso is a newly described technique of suspensionplasty, which aims to obviate concerns regarding previously described methods. The purpose of this study was to compare subsidence between the APL lasso and 2 other common methods, APL sling and flexor carpi radialis LRTI, after trapeziectomy in cadaveric forearms. METHODS: Ten cadaveric forearms were prepared on a custom-made plinth to recreate pinch grip upon the loading of previously identified muscles. A sequence of procedures was performed, with radiographs taken after each to assess the subsidence. RESULTS: The APL lasso was superior to simple trapeziectomy and flexor carpi radialis LRTI in preventing subsidence. CONCLUSIONS: The APL lasso was superior to simple trapeziectomy and flexor carpi radialis LRTI in preventing subsidence, and it may be a viable alternative when considering suspension methods after trapeziectomy. CLINICAL RELEVANCE: The APL lasso may be considered when trying to prevent subsidence after trapeziectomy.

Functional Recovery Following Trapeziectomy and Ligament Reconstruction and Tendon Interposition: A Prospective Longitudinal Study.

PURPOSE: Patients undergoing surgery for trapeziometacarpal (TMC) joint arthritis require preoperative counseling on the expectations of surgery. This study aims to document the objective and functional recovery over the initial 12 months following trapeziectomy and ligament reconstruction with tendon interposition (LRTI). METHODS: We prospectively followed 55 patients with symptomatic TMC joint osteoarthritis after trapeziectomy and LRTI. Patients were assessed on functional outcome measures, pain, and objective outcomes of grip, tip and key pinch strength, and range of motion. Outcomes were recorded preoperatively and at 3, 6, 9, and 12 months after surgery. RESULTS: Outcome measures of Disabilities of the Arm, Shoulder, and Hand (DASH), Patient-Rated Wrist Evaluation (PRWE), and pain, improved significantly after surgery at each 3-month interval up to 9 months. Palmar and radial abduction were significantly improved compared to their preoperative ranges, but opposition was unchanged. Power grip significantly exceeded the preoperative strength at 6 months and further increased at 9 months. Tip pinch significantly exceeded the preoperative strength at 12 months. There was no difference in the key pinch strength compared to the preoperative strength. CONCLUSIONS: Over a follow-up period of 12 months, trapeziectomy and LRTI is an effective treatment in significantly reducing pain in 80% of patients. Although normal patient-reported outcome measures of DASH and PRWE are not regained, when compared to normative values, these measures are significantly improved; the improvement plateaus at 9 months. Patients can expect to attain 37% and 46% of their eventual measured DASH and PRWE scores, respectively, at 3 months, and 82% and 79% of their eventual measured DASH and PRWE scores, respectively, at 6 months. Grip strength exceeded the preoperative strength by 15% at 6 months and by 30% at 9 months. Tip pinch strength significantly exceeded the preoperative strength by 20% at 9 months. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic II.

The Biomechanical Consequences of Trapeziectomy and Partial Trapezoidectomy in the Treatment of Thumb Carpometacarpal and Scaphotrapeziotrapezoid Arthritis.

PURPOSE: To determine, using a biomechanical cadaveric model, whether, in the treatment of thumb carpometacarpal and scaphotrapeziotrapezoid arthritis, partial trapezoid resection following trapeziectomy causes carpal, specifically lunocapitate and scapholunate, instability. METHODS: Eight fresh-frozen mid-forearm cadaver specimens with type I lunates and devoid of basilar thumb arthritis were used in the study. Specimens were mounted onto a wrist simulator applying cyclical wrist flexion/extension and radial/ulnar deviation motions. Carpal kinematics, specifically lunocapitate and scapholunate joint relationships, were measured at 4 different conditions: (1) a native intact state, (2) after trapeziectomy, (3) after 2-mm partial trapezoid resection, and (4) after 4-mm partial trapezoid resection. RESULTS: During both flexion/extension and radial/ulnar deviation of the wrist, the lunocapitate and scapholunate joint relationship did not show any notable change following any of trapeziectomy, 2-mm, or 4-mm trapezoid resection compared with the intact state. Changes to the lunocapitate and scapholunate angles were clinically insignificant-a maximum of 6° and 4° change, respectively. CONCLUSIONS: This biomechanical cadaveric study shows that performing a trapeziectomy followed by up to 4 mm of proximal trapezoid resection has a negligible effect upon carpal, specifically lunocapitate and scapholunate, stability. Further research is needed to elucidate the long-term clinical consequences of limited trapezoid resection in vivo. CLINICAL RELEVANCE: There may be no clinically relevant effects of resection of up to 4 mm of trapezoid in the surgical management of combined basilar thumb and scaphotrapeziotrapezoid arthritis.

Dry Wrist Arthroscopy for Radial-Sided Wrist Disorders.

The development of wrist arthroscopy has been useful in diagnosis, prognosis, and treatment of both ligament and osseous injuries. As the treatment indications and techniques become more refined, this article explores the role of dry arthroscopy to treat radial-sided disorders of the wrist.

[Revision surgery after resection arthroplasty of the thumb saddle joint]. / Revisionsoperationen nach Resektionsarthroplastiken am Daumensattelgelenk.

BACKGROUND: Resection arthroplasty still is the gold standard for the treatment of basal thumb arthritis. In most patients, satisfactory results can be expected. However, the few patients with persisting problems are a challenge for the hand surgeon. They may complain of neuromas, tendinitis of the flexor carpi radialis (FCR) tendon, impingement and/or proximalization of the first metacarpal, arthritis of the scaphotrapezoidal joint or carpal collapse in the case of pre-existing scapholunate instability. DIAGNOSIS: This includes subtle clinical examination. Radiography may be completed by a CT scan. Probational infiltration is a helpful tool to confirm diagnosis and may be the first step of a conservative treatment, when supplemented by orthoses. TREATMENT: Revision surgery is guided by the nature of the present problem. Neurolysis should be indicated cautiously and performed according to existing principles. FCR tendinitis is treated by release or resection of the tendon. Impingement of the first metacarpal is treated by repeat resection and tendon interposition, proximalization by additional suspension arthroplasty or by arthrodesis between the bases of the first and second metacarpals. In the case of scaphotrapezoidal arthritis, the proximal third of the trapezoid is resected, whereas destabilization of the scaphoid with consecutive carpal collapse may necessitate midcarpal fusion.

Evaluation of the PROMIS Upper Extremity Computer Adaptive Test Against Validated Patient-Reported Outcomes in Patients With Basilar Thumb Arthritis.

PURPOSE: The Patient-Reported Outcomes Measurement Information System (PROMIS) Upper Extremity (UE) computer adaptive test was developed to reduce test burden and improve precision. We hypothesized that, in patients with thumb basilar joint arthritis (BJA), (1) PROMIS UE would correlate with established patient-outcomes (PROs), (2) PROMIS UE would require less time and fewer questions than current metrics, (3) there would be no floor or ceiling effects, and (4) PROMIS UE would not correlate with radiographic disease severity. METHODS: Patients presenting with a primary diagnosis of thumb BJA completed the Quick Disabilities of the Arm Shoulder and Hand (QuickDASH), Thumb Disability Examination (TDX), Patient-Rated Wrist Hand Evaluation (PRWHE), and PROMIS UE. Radiographic disease severity as described by the Eaton scoring system was recorded. The relationships among PROs were described with Spearman correlation coefficients. The presence of a floor or ceiling effect was confirmed if greater than 15% of patients achieved the lowest or the highest possible score, respectively. RESULTS: One hundred patients with thumb BJA formed the sample for this study. A good to excellent correlation was identified between PROMIS UE and QuickDASH. There were good correlations between PROMIS UE and TDX as well as PRWHE. The PROMIS UE was significantly less time consuming (average: 58.5 seconds vs QuickDASH, 92.2; TDX, 62.6; and PRWHE, 144.7), and required fewer questions than current metrics (average: 4.9 questions vs QuickDASH, 11; TDX, 20; and, 15). In addition, there were no appreciable floor or ceiling effects. Radiographic disease severity did not correlate with PROMIS UE. CONCLUSIONS: The PROMIS UE has a good to excellent correlation with QuickDASH and good correlations with PRWHE and TDX. In addition, PROMIS UE required less time and fewer questions than established PROs. There were no floor or ceiling effects. Used as a single PRO, PROMIS UE may be a practical alternative to legacy scales in patients with thumb BJA. CLINICAL RELEVANCE: The PROMIS UE PRO instrument may be a valuable addition in the assessment of patients with basilar thumb arthritis.

Suture Suspension Arthroplasty for the Treatment of Thumb Carpometacarpal Arthritis.

PURPOSE: Most studies have demonstrated little difference in the outcome of the various techniques proposed for the surgical treatment of thumb carpometacarpal (CMC) arthritis. However, the difficulty and time required to perform each technique vary widely. In addition, the introduction of recent implants has increased the cost of the overall procedure. We hypothesize that using a simple, yet stable, suture suspension technique without tendon interposition or ligament reconstruction yields similar results to conventional approaches with less operative time. METHODS: Three hundred twenty consecutive patients underwent thumb CMC arthroplasty by trapezial excision and metacarpal suspension using #2 high-strength orthopedic suture locked weave alone passed from the distal most abductor pollicis longus and flexor carpi radialis insertions without K-wire fixation or tendon transfer. Average duration of preoperative symptoms was 17.8 months. Patient radiographs were graded for arthritis severity and a visual analog scale (VAS) pain score (scale 0-10) obtained. Postoperative clinical and radiological follow-up averaged 5.4 years (minimum, 24 months). RESULTS: The average age at surgery was 57.3 years and there were 221 women (243 procedures) and 65 men (77 procedures). Average total operative time was 23.4 minutes. The dominant hand was involved in 52% of patients. All had prior treatment including orthoses and nonsteroidal anti-inflammatory drugs with 312 having had at least 1 steroid injection. Five patients had stage 1, 134 had stage 2, 164 had stage 3, and 17 had stage 4 disease on radiographs. Average trapezial space height on final follow-up radiographs was 0.8 cm. Two patients had complete trapezial space collapse and required a revision procedure. The average VAS score was 0.6 with pain eliminated in 269 thumbs, minimal in 49, and unchanged/worse in 2. All patients that were employed at the time of surgery returned to work at an average of 2.3 months (range, 3-16 weeks). CONCLUSIONS: Suture suspension thumb CMC arthroplasty provides comparable clinical results and several advantages over many current techniques that are described in the literature. The advantages include shortened operative time, inherent stability of the thumb metacarpal height, and no necessity for K-wire fixation, tendon transfers, or implants. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Failed Thumb Carpometacarpal Arthroplasty: Common Etiologies and Surgical Options for Revision.

Carpometacarpal (CMC) arthroplasty surgery, although modifications have occurred over time, continues to be commonly performed and has provided patients with their desired pain relief and return of function. The complications of primary surgery, although relatively rare, can present in various clinical ways. An understanding of the underlying anatomy, pathology of coexisting conditions, and specific techniques used in the primary surgery is required to make the best recommendation for a patient with residual pain following primary CMC arthroplasty. The purpose of this review is to provide insights into the history of CMC arthroplasty and reasons for failure and to offer an algorithmic treatment approach for the clinical problem of persistent postoperative symptoms.

Revision Ligament Reconstruction Tendon Interposition for Trapeziometacarpal Arthritis: A Case-Control Investigation.

PURPOSE: To test the null hypothesis that there is no difference in patient-reported and objective outcomes of revision ligament reconstruction and tendon interposition (LRTI) compared with primary LRTI. METHODS: This case-control investigation enrolled 10 patients who had undergone revision LRTI at a tertiary care center. All patients had previously undergone primary trapeziectomy with LRTI. Patients with a minimum of 2 years' follow-up were eligible. All patients completed an in-office study evaluation. Controls (treated only with primary LRTI) were matched from our practice to reach a 1:2 case-control ratio. Outcome measures included Michigan Hand Questionnaire (primary outcome), Quick-Disability of the Arm, Hand, and Shoulder (QuickDASH) questionnaire, visual analog scale (VAS) for pain and improvement, and physical examination. Statistical analyses were conducted to compare patient groups. RESULTS: Patients who underwent revision LRTI reported significantly worse outcomes on all measured standardized questionnaires compared with primary patients. The Michigan Hand Questionnaire indicated worse overall outcomes (54 vs 79) as well as worse pain, appearance, and ability to complete activities of daily living. Compared with those who did not undergo revision LRTI, patients who did also reported more impairment (Quick-Disability of the Arm, Hand, and Shoulder, 47 vs 23), greater pain (VAS pain, 6.3 vs 1), and less improvement after surgery (VAS improvement, 2.7 vs 7.9). There was also a significantly higher rate of patient-reported depression in the revision LRTI group (50% vs 10% of patients treated with primary LRTI). We did not find a significant difference in objective outcomes of pinch strength, grip strength, and thumb palmar abduction between the 2 groups. CONCLUSION: After revision LRTI, patient-reported outcomes indicate worse perceived function and greater pain than are expected following primary LRTI despite similar motion and strength. Revision surgery can be offered in the setting of persistent or recurrent symptoms, but patients should be counseled that improvement of symptoms is unpredictable. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic III.

Double tightrope for basilar thumb arthritis.

Several surgical options exist for the treatment of basilar thumb joint arthritis. Suspending the thumb metacarpal with a suture button device provides a stabilizing force to maintain pinch strength, precludes the necessary healing time associated with ligamentous reconstruction and allows for earlier motion and return to work, and creates a stable construct that may prevent metacarpal subsidence over time. One of the concerns with this technique is over-tightening of the suture device, which results with impingement of the thumb and index metacarpal bases. We present a surgical technique of open trapeziectomy, simultaneous application of 2 Mini TightRope button devices to provide additional stabilization that prevents impingement of the thumb and index finger metacarpal, with imbrication of the flexor carpi radialis and abductor pollicis longus tendons as reinforcement of the construct.

Early Thumb Carpometacarpal Subluxation Stabilized with a Mini TightRope: A Report of Two Cases.

Two patients with thumb carpometacarpal instability were stabilized using a suture suspension device. Both patients had symptomatic thumb carpometacarpal instability in the setting of clinical hyperlaxity without known connective tissue disorder that was recalcitrant to nonsurgical modalities. Both patients had significant, lasting improvement in their pain and function with excellent radiographic outcomes. Suture suspension as a treatment for thumb carpometacarpal instability with an intact trapezium is an effective alternative to ligamentous reconstruction that avoids donor site morbidity and may have added benefit in patients with underlying ligamentous laxity.

Inter- and Intra-observer Agreement of Visual Estimation, Goniometric and Radiographic Measurement of Passive Thumb Metacarpophalangeal Joint Hyperextension.

Background: Reliable methods for measuring range of motion is important for hand therapists. Currently, there is no gold standard for the measurement of thumb metacarpophalangeal joint (MCPJ) hyperextension. We hypothesised that visual and goniometric measurements of thumb MCPJ hyperextension vary greater than 10° from radiographic measurements, and between observers. Methods: Twenty-six fresh-frozen hands were measured by a senior orthopaedic resident and fellowship trained hand surgeon. Passive thumb MCPJ hyperextension was measured by visual estimation, goniometry and axis measurement on a lateral thumb radiograph. Raters were blinded to each other's and their own prior measurements. Descriptive statistics were recorded for measurement type and inter-observer agreement using a two-way intra-class correlation coefficient (ICC). Intra-observer agreement was calculated using concordance correlation coefficient (CCC). Bland-Altman plots identified trends, systemic differences or potential outliers. Results: Mean measurements for both raters were similar for visual estimation and radiographic measurements. Mean goniometric measurements were twice as high for Rater B, and closer to radiographic measurements. For both raters, mean radiographic measurements were 10° greater than the other two methods. For inter-rater agreement, measurements were within 10° most frequently with radiographic measurement, then visual estimates, and least by goniometer measurements. Rater B had better agreement comparing visual and goniometric to radiographic measurements. Conclusions: Radiographic measurement has the best inter-observer agreement and precision for evaluating passive thumb MCPJ hyperextension, especially considering adjunct corrective procedures when performing a soft-tissue basal joint arthroplasty. Rater experience improves precision, but there is still poor agreement between visual estimates and goniometer measurements compared to radiographic measurements, as the former two underestimate hyperextension by 10°. Development of a standard method of clinical measurement is needed to improve reliability.

Efficacy and Safety of Different Trapezium Implants for Trapeziometacarpal Joint Osteoarthritis: A Systematic Review and Meta-Analysis.

Background: The trapeziometacarpal joint (TMCJ) is the most common hand joint affected by osteoarthritis (OA), and trapezium implant arthroplasty is a potential treatment for recalcitrant OA. This meta-analysis aimed to investigate the efficacy and safety of various trapezium implants as an interventional option for TMCJ OA. Methods: Web of Science, PubMed, Scopus, Google Scholar, and Cochrane library databases were searched for relevant studies up to May 28, 2022. Preferred Reported Items for Systematic Review and Meta-Analysis guidelines were adhered to, and the protocol was registered in PROSPERO. The methodological quality was assessed by National Heart, Lung, and Blood Institute tools for observational studies and the Cochrane risk of bias tool. Subgroup analyses were performed on different replacement implants; the analysis was done using Open Meta-Analyst software and P values <.05 were considered statistically significant. Results: A total of 123 studies comprising 5752 patients were included. Total joint replacement (TJR) implants demonstrate greater significant improvements in visual analogue scale pain scores postoperatively. Interposition with partial trapezial resection implants were associated with highest grip strength and highest reduction in the Disabilities of the Arm, Shoulder, and Hand (DASH) score. Revision rates were highest in TJR (12.3%) and lowest in interposition with partial trapezial resection (6.2%). Conclusion: Total joint replacement and interposition with partial trapezial resection implants improve pain score, grip strength, and DASH scores more than other implant options. Future studies should focus on high-quality randomized clinical trials comparing different implants to accumulate higher quality evidence and more reliable conclusions.

Systematic Comparison of Ligament Reconstruction With Tendon Interposition and Suture-Button Suspensionplasty for Trapeziometacarpal Osteoarthritis.

Ligament reconstruction tendon interposition (LRTI) and suture-button suspensionplasty (SBS) are both common treatment options for trapeziometacarpal osteoarthritis. The primary purpose of this systematic review was to compare the subjective improvement in patient-reported outcomes in regard to disability for patients undergoing LRTI and SBS for trapeziometacarpal osteoarthritis. A secondary purpose was to compare the subjective improvement, objective outcome scores, and complication rates following both procedures. We performed a systematic review using PubMed, Scopus, and Embase to compare the clinical outcomes of LRTI and SBS. Inclusion criteria were level I-IV evidence articles reporting postoperative Disabilities of the Arm, Shoulder, and Hand (DASH) or QuickDASH scores. Study methodological quality, risk of bias, and recommendation strength were assessed. This systematic review included 31 studies for final analysis with 1289 thumbs undergoing LRTI (25 studies) and 113 thumbs undergoing SBS (6 studies). Both procedures demonstrated similar improvement in DASH and/or QuickDASH scores, while key pinch and grip strength inconsistently improved following both procedures. Complication rate was similar between the 2 procedures; LRTI 12% and SBS 13%. Although both LRTI and SBS seem to provide improved short-term patient-reported functional improvement and objective strength, there was significant heterogeneity within the included studies, and those studies discussing SBS were of lower quality evidence than those of LRTI. Thus, to truly delineate whether a difference exists between these 2 techniques for the treatment of first carpometacarpal joint arthritis, larger prospectively designed studies of high-quality evidence are necessary.

The Effect of Thumb Carpometacarpal Joint Corticosteroid Injections on Outcomes Following Arthroplasty.

BACKGROUND: Prior studies suggest steroid injections may affect infection rates following thumb carpometacarpal joint (CMCJ) arthroplasty. However, it is unclear whether injections prior to CMCJ arthroplasty affect functional outcomes, primarily Quick Disabilities of the Arm, Shoulder, and Hand (qDASH). METHODS: We retrospectively identified patients who underwent thumb CMCJ arthroplasty from 2015 to 2019. Patients who had qDASH scores reported preoperatively, and at 5 and 11 months postoperatively were included. Charts were reviewed for the presence or absence of prior corticosteroid injection to the CMCJ and complications. Delta qDASH was calculated by subtracting the patients' postoperative qDASH scores from the preoperative qDASH scores. RESULTS: In all, 350 CMCJ arthroplasty patients were identified, 177 who had received at least 1 steroid injection and 173 who were steroid-naïve. No significant differences existed in delta qDASH scores postoperatively between the injection and naïve groups at 5 months (28.5 vs 28.6) or 11 months (31.2 vs 31.9). Whereas there were no significant differences in rates of major complications between the 2 groups, minor complications were higher in the injection group (16.4% vs 9.2%). Patients who received more than 3 injections did not have worse 5-month or 11-month delta qDASH scores or complication rates than those with fewer than 3. CONCLUSIONS: Preoperative CMCJ steroid injection status does not affect major complication rates or functional outcomes following CMCJ arthroplasty. However, injections increase the rate of minor complications. The qDASH and complication rates following CMCJ arthroplasty are not affected by receiving greater than 3 injections preoperatively.

Wide-Awake Local Anesthesia No Tourniquet for Rhizarthrosis Surgery: Technique and Experience for 16 Consecutive Cases.

Since it was described, wide-awake local anaesthesia no tourniquet (WALANT) has gained popularity. Our department has started using WALANT for hand surgery with increasing complexity. We present our results with WALANT rhizarthrosis surgery, including prosthetic replacement, trapeziectomy with suture button suspensionplasty and revision surgery. A retrospective review of all rhizarthrosis procedures under WALANT was performed from April 2021 to July 2022. We included patients who fulfilled inclusion criteria and had adequate imaging and clinical follow-up. A satisfaction survey was performed by telephone. Surgical time, complications, conversion to conventional anesthesia, pain, anxiety and global satisfaction were recorded. Tumescent anesthesia is performed 20-25 minutes before surgery, and is performed in four or five strategic locations that allow adequate anesthesia and vasoconstriction for the procedure to be comfortably carried out. We observed a series of 16 sequential surgeries involving 14 patients. All were female with a mean age of 65 years. Fourteen cases were performed due to primary rhizarthrosis, eight trapeziectomies with suture button suspensionplasty, six prosthetic replacements, and two revision surgeries. One patient needed to be converted to conventional anaesthesia due to anxiety during the procedure. Mean procedure time was 73 minutes. There were no WALANT-related complications. Mean patient-reported satisfaction with the anesthetic technique was a 9 (on a scale from 1 to 10) and 100% of patients would choose to undergo surgery with WALANT anesthesia for a future procedure. We find it useful to actively engage the patients during surgery to keep them comfortable and also help the surgeons assess stability and functional results. After wound closure, the hand is shown to the patient and he performs various tasks. There is somewhat of a learning curve for rhizarthrosis surgery under WALANT; patient comfort can be achieved through an adequate anesthetic technique and reassurance before and during surgery. We recommend that the first few cases be done in the presence of an anesthesiologist and a fasting patient in case there is a need to convert to conventional anesthesia. Wide awake rhizarthrosis surgery, even revision surgery, is safe and pain-free. Patient-reported satisfaction is also high. The authors find that including patient participation in their own surgery might be promising for post-op rehabilitation. There are limitations in this study such as the absence of a control conventional anesthesia group, the satisfaction questionnaire was not done immediately post-operatively, as such, a memory bias cannot be excluded, and it is not yet validated for the Portuguese population.
