Recurrence of Dupuytren’s contracture: A consensus-based definition

Purpose: One of the major determinants of Dupyutren disease (DD) treatment efficacy is recurrence of the contracture. Unfortunately, lack of agreement in the literature on what constitutes recurrence makes it nearly impossible to compare the multiple treatments alternatives available today. The aim of this study is to bring an unbiased pool of experts to agree upon what would be considered a recurrence of DD after treatment; and from that consensus establish a much-needed definition for DD recurrence. Methods: To reach an expert consensus on the definition of recurrence we used the Delphi method and invited 43 Dupuytren’s research and treatment experts from 10 countries to participate by answering a series of questionnaire rounds. After each round the answers were analyzed and the experts received a feedback report with another questionnaire round to further hone in of the definition. We defined consensus when at least 70% of the experts agreed on a topic. Results: Twenty-one experts agreed to participate in this study. After four consensus rounds, we agreed that DD recurrence should be defined as “more than 20 degrees of contracture recurrence in any treated joint at one year post-treatment compared to six weeks post-treatment”. In addition, “recurrence should be reported individually for every treated joint” and afterwards measurements should be repeated and reported yearly. Conclusion: This study provides the most comprehensive to date definition of what should be considered recurrence of DD. These standardized criteria should allow us to better evaluate the many treatment alternatives

Patient-Reported Outcomes and Function after Surgical Repair of the Ulnar Collateral Ligament of the Thumb

Purpose: The purpose of this study was to report prospectively collected patient-reported outcomes of patients who underwent open thumb ulnar collateral ligament (UCL) repair and to find risk factors associated with poor patient-reported outcomes. Methods: Patients undergoing open surgical repair for a complete thumb UCL rupture were included between December 2011 and February 2021. Michigan Hand Outcomes Questionnaire (MHQ) total scores at baseline were compared to MHQ total scores at three and 12 months after surgery. Associations between the 12-month MHQ total score and several variables (i.e., sex, injury to surgery time, K-wire immobilization) were analyzed. Results: Seventy-six patients were included. From baseline to three and 12 months after surgery, patients improved significantly with a mean MHQ total score of 65 (standard deviation [SD] 15) to 78 (SD 14) and 87 (SD 12), respectively. We did not find any differences in outcomes between patients who underwent surgery in the acute (&lt;3 weeks) setting compared to a delayed setting (&lt;6 months). Conclusions: We found that patient-reported outcomes improve significantly at three and 12 months after open surgical repair of the thumb UCL compared to baseline. We did not find an association between injury to surgery time and lower MHQ total scores. This suggests that acute repair for full-thickness UCL tears might not always be necessary.

Incision techniques for trigger thumb release:a comparison of outcomes of four types of skin incision

Although trigger thumb release is commonly performed, there is no consensus on the optimal skin incision. This study aimed to compare outcomes of four incision techniques, including V-shaped, oblique, transverse and longitudinal incisions. Outcomes included the Michigan Hand Outcomes Questionnaire, satisfaction with the treatment and postoperative complications. The results of 875 patients who underwent trigger thumb release were assessed. All groups demonstrated improvement in self-reported hand function (range of 10-14 points), pain (25-27 points) and aesthetics (4-7 points) from baseline to 3 months postoperatively with no differences between incision techniques. Of the patients, 76% reported good or excellent satisfaction with the outcome of treatment. Satisfaction and complication rates of the different incision techniques were similar. These findings imply that there is no clear benefit of one type of incision over another for trigger thumb release, suggesting that surgeons may use the technique of their preference.Level of evidence: II

Ultrasonographic quantification of intrinsic hand muscle cross-sectional area; Reliability and validity for predicting muscle strength

Objective To investigate whether ultrasonographic measurement of the cross-sectional area (CSA) of the intrinsic hand muscles can be used to predict muscle strength in a valid and reliable manner, and to determine if this method can be used for follow-up of patients with peripheral nerve injury between the wrist and elbow. Design Repeated-measures cross-sectional study. Setting Clinical and academic hospital. Participants Healthy adults (n=31) and patients with ulnar and median nerve injuries (n=16) between the wrist and elbow who were visiting the Erasmus Medical Center or Maasstad Hospital were included in the study (N=47). Interventions Not applicable. Main Outcome Measures Correlation between measured muscle CSA and strength and assessment of inter- and intrarater reliability. Ultrasound and strength measurements of the intrinsic hand muscles were conducted bilaterally. To establish validity, the CSA of 4 muscles (abductor digiti minimi, first dorsal interosseus, abductor pollicis brevis, opponens pollicis) was compared with strength measurements of the same muscles conducted with the Rotterdam Intrinsic Hand Myometer. Repeated measures were conducted to assess inter- and intrarater reliability. Results The assessed CSA strongly correlated with strength measurements, with correlations ranging from 0.82 to 0.93 in healthy volunteers and from 0.63 to 0.94 in patients. Test-retest reliability showed excellent intrarater reliability (intraclass correlation coefficient range, 0.99-1.00) in patients and volunteers and good interrater reliability (intraclass correlation coefficient range, 0.88-0.95) in healthy volunteers. Conclusions We found that ultrasound is a valid and reliable method to assess the CSA of specific muscles in the hand. Therefore, this technique could be useful to monitor muscle reinnervation in patients suffering from peripheral nerve injury as a valuable addition to strength dynamometers

Arthroscopic debridement does not enhance surgical treatment of intra-articular distal radius fractures: a randomized controlled trial

The aim of this study was to determine the difference in functional outcomes after open reduction and internal fixation (ORIF) with and without arthroscopic debridement in adults with displaced intra-articular distal radius fractures. In this multicentre trial, 50 patients were randomized between ORIF with or without arthroscopic debridement. The primary outcome measure was the Patient-Rated Wrist Evaluation (PRWE) score. Secondary outcome measures were Disabilities of the Arm, Shoulder, and Hand (DASH) questionnaire, pain scores, range of wrist motion, grip strength, and complications. Median PRWE was worse for the intervention group at 3 months and was equal for both groups at 12 months. The secondary outcome measures did not show consistent patterns of differences at different time-points of follow-up. We conclude that patients treated with additional arthroscopy to remove intra-articular hematoma and debris did not have better outcomes than those treated with ORIF alone. We therefore do not recommend arthroscopy for removal of hematoma and debris when surgically fixing distal radius fractures. Level of evidence:

Management of Recurrent Carpal Tunnel Syndrome: Systematic Review and Meta-Analysis

Purpose: Few comparisons have been performed between the outcomes of surgical techniques for recurrent carpal tunnel syndrome. Using a meta-analysis, this study aimed to compare the outcomes of different surgical techniques using the Boston Carpal Tunnel Questionnaire (BCTQ) and visual analog scale (VAS) for pain as outcomes. Methods: The following categories were used to define the study's inclusion criteria: population, intervention, comparator, outcomes, and study design. Studies were examined by 2 reviewers, and the Preferred Reporting Items for Systematic Review and Meta-Analyses guidelines were followed. The studies were assigned to 1 of the following treatment groups: decompression with or without neurolysis, autologous fat transfer, hypothenar fat pad, pedicled or free flap, and “other.” For our primary outcome, we compared improvement using the BCTQ and VAS for pain between the treatment groups. For our secondary outcome, postoperative BCTQ and VAS pain values were compared. Results: Fourteen studies were included: 5 case series with postoperative data only and 9 pre-post studies without a control group. With regard to our primary outcome, the studies reported an average improvement of 1.2 points (95% confidence interval [CI][1.5, 0.9]) on a scale of 1–5 on the symptoms severity scale (SSS) of the BCTQ, 1.9 points (95% CI [1.37, 0.79]) on a scale of 1–5 on the function severity scale of the BCTQ, and 3.8 points (95% CI [4.9, 2.6]) on a scale of 1–10 on the VAS for pain. We only found significantly lesser improvement in the “other” treatment group than in the hypothenar fat pad group and autologous fat transfer group using the SSS. The hypothenar fat pad group had the best reported postoperative SSS score of 1.75 (95% CI [1.24, 2.25]), function severity scale score of 1.55 (95% CI [1.20, 1.90]), and VAS pain score of 1.45 (95% CI [0.83, 2.07]). Conclusions: All the techniques showed clinically important improvements in all the outcomes. We found lesser improvement in the “other” treatment group than in the hypothenar fat pad group and autologous fat transfer group using the SSS. We found that the hypothenar fat pad group had the best reported postoperative values in our secondary analysis. Type of study/level of evidence: Therapeutic IV

The never-ending battle between proximal row carpectomy and four corner arthrodesis: A systematic review and meta-analysis for the final verdict

While scaphoid excision combined with Four Corner Arthrodesis (FCA) or Proximal Row Carpectomy (PRC) is a commonly-used salvage procedures to treat type two and type three Scapholunate Advanced Collapse (SLAC) and Scaphoid Nonunion Advanced Collapse (SNAC)-induced degenerative arthritis, controversy remains over which treatment intervention provides superior outcomes. We searched for articles comparing a range of motion, grip strength, complications requiring reoperation, conversion to wrist arthrodesis, pain, and disability of shoulder and arm scores between FCA and PRC-treated patients. The risk of bias was assessed using the National Institutes of Health (NIH) quality assessment tool. We performed a meta-analysis using Random-Effects Models. Fifteen articles (10 retrospective, 2 cross-sectional, 1 prospective, and 2 randomized trials) were included. There was no significant difference between PRC and FCA in any of the different outcome measures. The risk of bias was found consistently high across all studies. Despite the lack of high-quality evidence, based on existing literature, we recommend PRC as the preferred choice of treatment because of the simplicity of the surgical procedure, lack of hardware-related complications, and comparable long-term outcomes.

Factors associated with self-reported pain and hand function following surgical A1 pulley release

Surgical A1 pulley release can considerably reduce pain and improve hand function, but individual outcomes are highly variable. This study aimed to identify factors contributing to self-reported pain and hand function 3 months postoperatively. We included 2681 patients who had received surgical treatment for a trigger finger or thumb and who completed the Michigan Hand outcomes Questionnaire (MHQ). Hierarchical linear regression models were used to investigate patient and clinical characteristics associated with postoperative pain and hand function. For both pain and hand function, the most influential factors associated with worse outcomes were worse MHQ scores at baseline (β 0.38 and 0.33, respectively) and ≥3 preoperative steroid injections (β -0.36 and -0.35). These factors indicated that patients with severe preoperative symptoms represent a group with a more advanced disease that is more difficult to treat. These findings can assist clinicians in patient counselling, expectation management and decision-making about the timing of the intervention.Level of evidence: II
