What’s New in Hand and Wrist Surgery 2021

Every month, JBJS publishes a review of the most pertinent and impactful studies published in the orthopaedic literature during the previous year in 14 specialty areas. Click here for a collection of all such OrthoBuzz Guest Editorial summaries.

This month, author Christopher J. Dy, MD, MPH summarizes the 5 most compelling findings from the 40 studies highlighted in the most recent “What’s New in Hand and Wrist Surgery.”

Carpal Tunnel Syndrome

–Corticosteroid injection is one modality for managing carpal tunnel syndrome, and a recent study examined the accuracy of needle placement1. Of 756 simulated injections, correct placement was noted for 572 (76%). The needle was placed in the median nerve 66 times (8.7%), and the carpal tunnel was missed 118 times (15.6%). As noted by the study authors, “safety of carpal tunnel injection remains an important concern.”

Cubital Tunnel Syndrome

–One recent study evaluating patient-reported outcomes of in situ decompression for cubital tunnel syndrome found that 66 (86%) of 77 patients were satisfied2. All of the patients who were not satisfied had preoperative weakness of the muscles innervated by the ulnar nerve.

Distal Radial Fracture

–A retrospective radiographic analysis of 273 uninjured adult distal radii found that the volar cortical angle (VCA) ranged from 23° to 43° (mean, 32°)3. With most volar locking plates having a fixed angle of 18° to 30°, there is a strong possibility of a mismatch between the patient’s VCA and the implant. If the patient’s VCA exceeds the implant’s fixed angle, undercorrection of sagittal tilt may result if the plate is used to guide reduction in treating a distal radial fracture.

Dupuytren Contracture

–A recent report presented a single surgeon’s experience over an 11-year time frame with 3 common treatments of Dupuytren contracture4. The rates of reintervention after needle aponeurotomy were 24% at 2 years and 61% at 5 years; after collagenase injection at the same time points, 41% and 55%; and after surgical fasciectomy, 4% at both 2 and 5 years. When factoring in cost, needle aponeurotomy appeared to be a high-value intervention.

Scapholunate Dissociation

–Among 203 patients who underwent  3-ligament tenodesis for scapholunate injury, improvement in patient-reported outcomes at 1 year was noted for 79%, but 10% had no change, and 11% had worse patient-reported outcomes5. Indications for 3-ligament tenodesis may need further clarification.

Cost-Effectiveness of Endoscopic vs Open Carpal Tunnel Release

Carpal tunnel release (CTR) is one of the most common upper-extremity procedures, with excellent outcomes and lasting benefits. When comparing the surgical options of open versus endoscopic CTR, studies have noted higher rates of transient nerve injury but lower risk of wound problems after endoscopic release. Long-term clinical outcomes appear to be similar between the 2 techniques.

What about the associated costs? This is a multidimensional question of particular relevance given the high economic impact of carpal tunnel syndrome, a leading cause of lost work time. Barnes et al. shed new light on the cost-effectiveness of endoscopic versus open CTR in a recent JBJS report, offering a look from societal and payer perspectives. In this cost-effectiveness analysis, the authors developed a Markov model to evaluate unilateral open versus endoscopic CTR in an office setting with local anesthesia and an operating room (OR) setting under monitored anesthesia care. Comprehensive outcomes data from published meta-analyses helped to inform the modeling, while the costs of CTR, performed from 2012 to 2016, were obtained from a large Medicare claims database.

The authors note that, with complications rates being relatively balanced between the 2 techniques, and differences in quality-adjusted life-years being small (<1 quality-adjusted life-day), “procedural and lost-productivity costs primarily drove the results.” (The model assumed 8.21 fewer days of missed work after endoscopic CTR.) Health-care costs are larger for endoscopic CTR, but “the impact of lost productivity was important.” For instance, endoscopic release in the OR setting becomes cost-effective if the patient’s expected return to work is even 1.2 days earlier than that following open CTR in the OR. However, because of the lower costs of performing open CTR in the office setting, endoscopic CTR in the OR is cost-effective only if the expected return to work is at least 3.9 days earlier than that following open CTR in the office.

Overall, the authors concluded that, from a payer perspective, endoscopic CTR is more expensive than open CTR and only becomes truly cost-effective if performed in an office setting under local anesthesia. However, from a societal perspective, earlier return to work may help tip the scales in favor of endoscopic release. The authors caution that additional research is needed to confirm their findings based on the latest surgical techniques and return-to-work protocols.

Patient Misperception of Musculoskeletal Disease Onset

Often when I ask patients about the reason for their visit, I inquire about specific events. For example, “What were you doing when you hurt your knee?” For acute injuries, they can usually describe the exact moment they tore their ACL or dislocated their shoulder. In an adolescent sports clinic, where I spend much of my time, this acute scenario is the norm, but what about patient conversations regarding gradual-onset disease processes such as carpal tunnel syndrome (CTS) or osteoarthritis? These pathologies develop over many years, but patients with such conditions may fixate on when their disease became symptomatic–and may therefore mistakenly attribute a chronic condition to an acute injury.

Lemmers et al. investigate this complex body-mind concept in the December 16, 2020 issue of The Journal. The authors sought to analyze factors associated with the misperception of disease onset due to the recent experience of symptoms in 121 adult patients with CTS, cubital tunnel syndrome, upper-extremity osteoarthritis, or rotator cuff tendinosis. The patients filled out questionnaires for depression, anxiety, pain catastrophizing, self-efficacy, and upper-extremity physical function, in addition to supplying basic demographic information.

Based on the responses, most patients understood that their problem was not new but was instead “age-appropriate.” However, 18% of patients perceived the sudden onset of symptoms as a “new” disease, and 24% felt the problem was related to at least 1 injury or event. After multivariable analysis, Lemmers et al. found that Hispanic ethnicity and publicly funded or no insurance were independently associated with the perception that an event/injury caused the problem. The authors candidly admit that this area needs much more research, but they surmise that this latter finding could be related to lower health literacy.

This work highlights that we need to make sure our patients understand exactly what is happening with their musculoskeletal system. Because misperception of a disease’s cause and onset could affect patient decision-making, it is incumbent upon us as surgeons to be vigilant for possible misconceptions during our shared decision-making discussions with patients. As Lemmers et al. conclude, “Patients who do not understand what is happening to their body might choose different health strategies than they would if their understanding were accurate.”

What’s New in Hand and Wrist Surgery 2020

Every month, JBJS publishes a review of the most pertinent and impactful studies published in the orthopaedic literature during the previous year in 13 subspecialties. Click here for a collection of OrthoBuzz summaries of these “What’s New” articles. This month, author Christopher J. Dy, MD, MPH selected the 5 most clinically compelling findings from the more than 50 studies summarized in the March 18, 2020 “What’s New in Hand and Wrist Surgery.”

Scaphoid Nonunion
—A retrospective case series investigating 3 treatments for scaphoid nonunion among >100 patients1 found the following:

  • Those receiving iliac crest bone graft (n=31), most of whom had carpal collapse with preserved proximal pole vascularity, had a union rate of 71%, a time-to-union of 19 weeks, and a reoperation rate of 23%.
  • Those receiving an intercompartmental supraretinacular artery flap (n=33), most of whom had osteonecrosis of the proximal pole and half of whom had carpal collapse, had a union rate of 79%, a time-to-union of 26 weeks, and a reoperation rate of 12%.
  • Those receiving a free vascularized medial femoral condyle flap (n=45), most of whom had carpal collapse, osteonecrosis, and prior surgery, had a union rate of 89%, a time-to-union of 16 weeks, and a reoperation rate of 16%.

—Among 13 patients with scaphoid nonunion and osteonecrosis who were treated with cancellous autograft packing and volar-plate fixation,2 there was 100% fracture union, with most achieving union within 18 weeks. However, preoperative carpal-collapse rates were not reported, making it difficult to assess the role of this procedure.

Finger Replantation: Financial Issues
—The frequency and success rates of finger replantation have been decreasing in the US. A review of physician reimbursement for these procedures3 found that replantation has lower reimbursement per work relative value unit (RVU) than many other common hand surgeries, including revision amputation, carpal tunnel release, and trigger finger surgery. This “relative devaluation” may help explain the decline in frequency and success of finger replantation.

Socioeconomics of Carpal Tunnel Syndrome
—Among patients seeking treatment for carpal tunnel syndrome, those from areas of “increased social deprivation” had worse physical function, pain interference, anxiety, and depression than patients from more affluent areas.4

Cubital Tunnel Syndrome
—A study of preoperative dynamic ultrasound in patients with cubital syndrome5 found that ultrasound was far more reliable than preoperative clinical examinations in predicting ulnar nerve stability within the cubital tunnel (88% match with intraoperative findings vs 12% match, respectively). Preoperative ultrasound may therefore help surgeons counsel patients about the possible need for nerve transposition.

What’s New in Hand Surgery 2019

Every month, JBJS publishes a review of the most pertinent and impactful studies published in the orthopaedic literature during the previous year in one of 13 subspecialties. Click here for a collection of all OrthoBuzz subspecialty summaries.

This month, Christopher J. Dy, MD, MPH, author of the March 20, 2019 “What’s New in Hand Surgery,” selected the five most compelling findings from among the 47 noteworthy studies summarized in the article.

Distal Radial Fractures
—A randomized trial comparing volar plate fixation to cast management in patients >60 years of age who had AO type-C distal radial fractures1 found that the volar plating group had better Patient-Rated Wrist Evaluation scores than the casting group after a minimum 24 months of follow-up. Maintenance of reduction was also better in the volar plating group. These findings are contrary to those of a similar randomized trial published in 2011, suggesting that there are patient-level and surgeon-level differences between the 2 environments in which the studies were conducted.

—Among 175 elderly patients with distal radial fractures treated nonoperatively and who showed acceptable radiographic reduction at 1 to 2 weeks, 28% had late displacement or malunion at the 3-month follow-up.2 Relative to cases in which reduction was maintained, cases with late displacement or malunion had lower grip strength and loss of the total wrist range of motion. However, there was no between-group difference in patient-reported functional measures, and the incidence of the most common complication—carpal tunnel syndrome—was the same in both groups.

Scaphoid Fractures
—Findings from a biomechanical study with cadavers suggest that 50% cortical healing of a scaphoid fracture after open reduction and internal fixation with a compression screw is sufficient to allow unrestricted activity.3 Constructs with a 50% osteotomy and compression screw showed the same load to failure as intact scaphoids, but load to failure in a group with a 75% osteotomy and compression screw was lower than that in the intact scaphoid group.

—Traditionally, surgeons have emphasized proximal pole vascularity in cases of scaphoid nonunion. However, a study of 35 scaphoid nonunions treated with nonvascularized bone grafting and a headless compression screw4 found that 33 fractures went on to union, despite evidence of compromised proximal pole vascularity in 14 of 32 patients who had histopathological data available.

Carpal Tunnel Syndrome
—A cross-sectional study analyzing data from 367 patients who presented for evaluation of carpal tunnel syndrome (CTS)5 found that those with the poorest socioeconomic status had worse PROMIS scores for physical function, pain interference, depression, and anxiety, compared with those in the least-deprived quartile. Deprived patients were also more likely to have a higher comorbidity burden and to use tobacco, both of which may influence outcomes after CTS treatment.

October 2018 Article Exchange with JOSPT

jospt_article_exchange_logo1In 2015, JBJS launched an “article exchange” collaboration with the Journal of Orthopaedic & Sports Physical Therapy (JOSPT) to support multidisciplinary integration, continuity of care, and excellent patient outcomes in orthopaedics and sports medicine.

During the month of October 2018, JBJS and OrthoBuzz readers will have open access to the JOSPT article titled “Validity of Clinical Small-Fiber Sensory Testing to Detect Small–Nerve Fiber Degeneration.”

This prospective, cross-sectional, diagnostic-accuracy study found that pinprick testing, followed by warm and cold tests if pinprick is normal, is a valid and cost-effective method to detect small-fiber degeneration in a carpal tunnel syndrome model of neuropathy.

JBJS 100: Bankart Repair, Carpal Tunnel Assessment

JBJS 100Under one name or another, The Journal of Bone & Joint Surgery has published quality orthopaedic content spanning three centuries. In 1919, our publication was called the Journal of Orthopaedic Surgery, and the first volume of that journal was Volume 1 of what we know today as JBJS.

Thus, the 24 issues we turn out in 2018 will constitute our 100th volume. To help celebrate this milestone, throughout the year we will be spotlighting 100 of the most influential JBJS articles on OrthoBuzz, making the original content openly accessible for a limited time.

Unlike the scientific rigor of Journal content, the selection of this list was not entirely scientific. About half we picked from “JBJS Classics,” which were chosen previously by current and past JBJS Editors-in-Chief and Deputy Editors. We also selected JBJS articles that have been cited more than 1,000 times in other publications, according to Google Scholar search results. Finally, we considered “activity” on the Web of Science and The Journal’s websites.

We hope you enjoy and benefit from reading these groundbreaking articles from JBJS, as we mark our 100th volume. Here are two more:

The Bankart Procedure: A Long-Term End-Result Study
C R Rowe, D Patel, W W Southmayd: JBJS, 1978 January; 60 (1): 1
This was the first large clinical series with long follow-up to report the findings and results of the open Bankart repair. The results were almost uniformly excellent or good, and this study contributed to the demise of nonanatomic shoulder repairs.

A Self-Administered Questionnaire for the Assessment of Severity of Symptoms and Functional Status in Carpal Tunnel Syndrome
D W Levine, B P Simmons, M J Koris, L H Daltroy, G G Hohl, A H Fossel, J N Katz: JBJS, 1993 January; 75 (11): 1585
Distinguishing interventions that work from those that don’t requires rigorous outcomes research, which, in turn, relies on standardized, patient-centered measures that have proven reliability and validity. Meeting these criteria are the Symptom Severity and Functional Status Scales for carpal tunnel syndrome described in this oft-cited JBJS study from 25 years ago.

The Carpal Tunnel Syndrome: Seventeen Years’ Experience in Diagnosis and Treatment of 654 Hands
George S. Phalen: JBJS, 1966 March; 48 (2): 211
Everything Phalen presented about carpal tunnel syndrome in 1966 holds true more than 50 years later. This includes his descriptions of the anatomical, epidemiologic, histologic, and clinical features of carpal tunnel syndrome and his emphasis on careful history-taking and physical examination.

Periprosthetic Bone Loss in Total Hip Arthroplasty: Polyethylene Wear Debris and the Concept of the Effective Joint Space
T P Schmalzried, M Jasty, W H Harris: JBJS, 1992 Jan; 74 (6): 849
The insights offered by these authors radically altered our thoughts about osteolysis. Using this concept of effective joint space, subsequent investigators and innovators identified methods and designs of hip replacements to retard osteolysis by limiting the generation and spread of particulate debris.

What’s New in Hand and Wrist Surgery

Hand Wrist for O'Buzz.jpegEvery month, JBJS publishes a Specialty Update—a review of some of the most pertinent and impactful studies published in one of 13 orthopaedic subspecialties during the previous year. Click here for a collection of all OrthoBuzz Specialty Update summaries.

This month, OrthoBuzz asked Sanjeev Kakar, MD, the author of the March 15, 2017 Specialty Update on hand and wrist surgery, to select five of the most clinically compelling findings from among the more than 40 he cited in the article.

Carpal Tunnel Syndrome

—The AAOS published updated clinical practice guidelines on the evaluation and treatment of carpal tunnel syndrome (CTS). Among the conclusions are the following:

  • Thenar atrophy is strongly associated with ruling in carpal tunnel syndrome but poorly associated with ruling it out.
  • High body mass index and repetitive hand and wrist actions are associated with an increased risk of developing CTS.
  • Surgical division of the transverse carpal ligament should relieve symptoms and improve function compared with nonoperative treatment.
  • There is no benefit to routine postoperative immobilization after CTS surgery.

Wrist Fracture

—If a distal radius fracture is displaced, especially in an elderly patient, should one proceed with nonoperative or operative treatment? A systematic review/meta-analysis1 involving more than 800 patients 60 years of age or older found that operatively treated patients had greater grip strength and better restoration of radiographic parameters than nonoperatively treated patients. However, those who underwent surgery also experienced more complications (primarily hardware-related) that required surgery.

Thumb and Digit Arthritis

—There are a myriad of treatments for the management of basilar thumb arthritis, ranging from trapeziectomy to fusion. Which one is better, especially if the scaphotrapeziotrapezoid joint is not involved? A prospective study was conducted randomizing women older than 40 with basal thumb joint arthritis to trapeziectomy and suspension arthroplasty or carpometacarpal joint arthrodesis. After a mean follow-up of 5.3 years, those in the trapeziectomy-suspension arthroplasty group had significantly better pain reduction and function.2 Researchers halted the study prematurely due to increased complications in the arthrodesis group.

Outcome Measurement Tools

—Among the many patient-reported outcome measures for the upper extremity, which should be used for which conditions? For distal radius fractures, a systematic approach has been proposed3 that captures outcomes across five domains: range of motion and grip strength, patient-reported scores of disability and function, complications, pain, and radiographs.4

—Is there any way to make the collection of patient-reported outcomes easier and less time-consuming? An assessment that compared two forms of computerized adaptive tests (CATs) with the DASH (Disabilities of the Arm, Shoulder and Hand) measure among 379 hand-clinic patients found that the CAT required fewer questions to complete than the DASH, yet maintained excellent reliability.5

March 2017 Article Exchange with JOSPT

JOSPT_Article_Exchange_Logo.pngIn 2015, JBJS launched an“article exchange” collaboration with the Journal of Orthopaedic & Sports Physical Therapy (JOSPT) to support multidisciplinary integration, continuity of care, and excellent patient outcomes in orthopaedics and sports medicine.

During the month of March 2017, JBJS and OrthoBuzz readers will have access to the JOSPT article titled “The Effectiveness of Manual Therapy Versus Surgery on Self-reported Function, Cervical Range of Motion, and Pinch Grip Force in Carpal Tunnel Syndrome: A Randomized Clinical Trial.”

In that clinical trial of 100 women with carpal tunnel syndrome randomized to receive either manual therapy or endoscopic decompression/release, researchers found that both interventions had similar outcomes in self-reported function and pinch-tip grip force at 3, 6, and 12 months of follow-up. However, at 1 month, there were significant between-group differences in favor of manual therapy. No changes in cervical range of motion were observed after either manual therapy or surgery at any time point.
