General Anxiety Is Associated with Problematic Initial Recovery After Carpal Tunnel Release

Psychological factors are associated with pain extent in patients with carpal tunnel syndrome

INTRODUCTION

Widespread pain may be related to psychosocial aspects in several musculoskeletal conditions, but the literature on carpal tunnel syndrome (CTS) is scarce.

OBJECTIVE

To determine the relationship between pain extent and psychological factors (catastrophizing, kinesiophobia, anxiety symptoms, and depression) in people with CTS.

METHODS

A cross-sectional study was conducted. The independent variables were: pain intensity, disability (QuickDASH), duration of symptoms, anxiety and depressive symptoms, catastrophizing, and kinesiophobia. The main outcome was: pain extent (% of total area and categories "pain within the median nerve-innervated territory" versus "extra-median nerve pain"). Correlation analysis was performed using Spearman's correlation coefficient. A linear regression model and binary logistic regression (both with forward selection) were performed to determine the main predictors of pain extent.

RESULTS

Forty-eight participants were included. A moderate positive correlation was found between catastrophizing (r = 0.455; p = 0.024) and disability (r = 0.448; p = 0.024) with total pain extent area. Regression models indicated that catastrophizing explained 22% of the variance in the pain extent (β = 0.003; 95% CI: 0.002-0.005), while kinesiophobia was the variable that best explained the distribution of pain in the extra-median territory (R2 Nagelkerke = 0.182). Null or weak correlations were found for the rest of the associations.

CONCLUSION

Catastrophizing and kinesiophobia were the main indicators of pain extent in people with CTS. Clinicians are advised to use specific questionnaires to check for the presence of catastrophizing or kinesiophobia in people with CTS and wider pain extension.

Is Pain in the Uninjured Arm Associated With Unhelpful Thoughts and Distress Regarding Symptoms During Recovery From Upper-Extremity Injury?

PURPOSE

During recovery from upper-extremity injury, patients sometimes express concerns regarding pain associated with increased use of the uninjured limb. Concerns about discomfort associated with increased use may represent a manifestation of unhelpful thoughts such as catastrophic thinking or kinesiophobia. We asked the following questions: (1) Among people recovering from an isolated unilateral upper-extremity injury, is pain intensity in the uninjured arm associated with unhelpful thoughts and feelings of distress regarding symptoms, accounting for other factors? (2) Is pain intensity in the injured extremity, magnitude of capability, or accommodation of pain associated with unhelpful thoughts and feelings of distress regarding symptoms?

METHODS

In this cross-sectional study of new or returning patients presenting to a musculoskeletal specialist for care for an upper-extremity injury, the patients completed scales that were used to measure the following: pain intensity in the uninjured arm, pain intensity in the injured arm, upper-extremity-specific magnitude of capability, symptoms of depression, symptoms of health anxiety, catastrophic thinking, and accommodation of pain. Multivariable analysis was used to evaluate factors associated with pain intensity in the uninjured arm, pain intensity in the injured arm, magnitude of capability, and pain accommodation, controlling for other demographic and injury-related factors.

RESULTS

Greater pain intensity in both uninjured and injured arms was independently associated with greater unhelpful thinking regarding symptoms. A greater magnitude of capability and pain accommodation were independently associated with less unhelpful thinking regarding symptoms.

CONCLUSIONS

Given that greater pain intensity in the uninjured upper extremity is associated with greater unhelpful thinking, clinicians can be attuned to patient concerns about contralateral pain. Clinicians can facilitate recovery from upper-extremity injury by evaluating the uninjured limb as well as identifying and ameliorating unhelpful thinking regarding symptoms.

Factors Associated with Preoperative Anxiety in Patients Undergoing Ambulatory Hand Surgery: A Cross-Sectional Observational Study

Background: Studies examining preoperative anxiety in patients awaiting hand surgery are scarce. Preoperative anxiety is a common reaction and can have a negative impact on treatment outcomes. The aim of this study was to assess the level of anxiety in patients undergoing hand surgery as a one-day procedure and to investigate the associations between patients' preoperative anxiety and selected sociodemographic, psychological, and clinical variables. Methods: We examined 121 patients (77.7% women) who were operated on in an ambulatory setting. The mean age was 52.6 years (range: 24-84 years). Preoperative anxiety was assessed according to the Amsterdam Preoperative Anxiety and Information Scale (APAIS). The Visual Analogue Scale was used to assess irritability, depression, and pain. Results: Univariate analyses showed significant correlations between patients' preoperative anxiety and increased age, surgery within a year since diagnosis, the presence of rehabilitation in their medical history, higher irritability, and living in rural areas. Multivariate analyses showed significant associations between patients' anxiety level and diagnosis of up to a year, a history of rehabilitation and the level of irritability. Conclusions: Patients undergoing hand surgery in an ambulatory surgery setting experience some preoperative anxiety. Younger patients, those with a shorter duration of disease, with a history of rehabilitation, those presenting intense irritability, and those living in rural areas may demand special attention.

The Effect of Patient-Reported Allergies on Patient-Reported Outcomes in Carpal Tunnel Release

BACKGROUND

Patient-reported allergies have been shown to be a risk factor for poor surgical outcomes in a variety of orthopedic procedures. The relationship between patient-reported allergies and outcomes in carpal tunnel surgery remains unclear.

METHODS

A retrospective electronic medical chart review was conducted on 390 patients who underwent primary carpal tunnel releases, without concomitant procedures, who completed preoperative and postoperative Quick Disabilities of Arm, Shoulder, and Hand or Patient-Rated Wrist Evaluation scores, with a minimum of 1-year follow-up. Patient demographic data and patient-reported outcome measures were collected. Patients were grouped based on the number of allergies reported (≤3 allergies or ≥4 allergies), and statistical analysis was performed.

RESULTS

Three hundred and ninety patients were included in the analysis (347 patients [89.0%] with ≤3 allergies; 43 patients [11.0%] with ≥4 allergies). Patients were predominantly female (n = 243, 62.3%), and the median age at surgery was 61 years. Patients with ≥4 allergies were more likely to be female (88.4% vs 59.1%), older (64.3 years vs 60.3 years), and more likely to be taking psychotropic medication (51.2% vs 28.2%). No differences were seen in patient-reported outcomes at any time point preoperatively or postoperatively, with both groups showing similar postoperative improvement.

CONCLUSIONS

Patients with a high number of reported allergies have similar improvement in patient-reported outcomes following carpal tunnel release as low-allergy cohorts.

Mental and behavioural disorders increase the risk of tendon rupture after flexor tendon repair in zone I and II

Introduction

The effect of mental and behavioural disorders (MBD) on the risk of tendon ruptures after flexor tendon repair is not well understood. This study aimed to analyse the association between MBD and tendon rupture after flexor tendon repair in zones I and II.

Methods

Data from the Swedish National Registry for Hand Surgery (HAKIR) on patients with a complete flexor tendon repair at our department between 2012 and 2019 were followed for a minimum of 2 years to assess the rate of rupture. Independent variables were collected from HAKIR and clinical records: prevalence MBD based on ICD-10 codes F0-F99, age, sex, injured tendon, number of injured fingers, day to surgery, core suture, digital nerve injury, smoking, injury mechanism, and rehabilitation method. Multiple logistic regression was used to assess the association between variables.

Results

A cohort of 593 patients with 49 ruptures (8.2%) was identified. Potential causes of rupture were non-adherence behaviour in 16 (33%), accidents in seven (14%), infections in six (12%), and no clear cause in 20 (41%) patients. Patients with MBD had an association to rupture (OR 3.6), 17.7% ruptures compared to 7.2% in patients with no diagnosed disorders. Patients >50 years of age had a higher risk compared to patients <25 years (OR 4.3), 15% compared to 3.9%' respectively. Men had a higher risk compared to women (OR 2.9), 10% compared to 4.3%' respectively.

Conclusion

We identified an association between the prevalence of mental and behavioural disorders and rupture after flexor tendon repair.

Is Pain in the Uninjured Leg Associated With Unhelpful Thoughts and Distress Regarding Symptoms During Recovery From Lower Extremity Injury?

BACKGROUND

Patients recovering from lower extremity injuries often interpret discomfort associated with increased use of the uninjured leg as a potential indication of harm. If expressed concerns regarding contralateral leg pain are associated with unhelpful thinking regarding symptoms, they can signal orthopaedic surgeons to gently reorient these thoughts to help improve comfort and capability during recovery.

QUESTIONS/PURPOSES

We asked: (1) Among people recovering from isolated traumatic lower extremity injury, is pain intensity in the uninjured leg associated with unhelpful thoughts and feelings of distress regarding symptoms, accounting for other factors? (2) Are pain intensity in the injured leg, magnitude of capability, and accommodation of pain associated with unhelpful thoughts and feelings of distress regarding symptoms?

METHODS

Between February 2020 and February 2022, we enrolled 139 patients presenting for an initial evaluation or return visit for any traumatic lower extremity injury at the offices of one of three musculoskeletal specialists. Patients had the option to decline filling out our surveys, but because of the cross-sectional design, required fields on the electronic survey tools, and monitored completion, there were few declines and few incomplete surveys. The median age of participants was 41 years (IQR 32 to 58), and 48% (67 of 139) were women. Fifty percent (70 of 139) injured their right leg. Sixty-five percent (91 of 139) had operative treatment of their fracture. Patients completed measures of pain intensity in the uninjured leg, pain intensity in the injured leg, lower extremity-specific magnitude of capability, symptoms of depression, symptoms of health anxiety, catastrophic thinking, and accommodation of pain. Multivariable analysis sought factors independently associated with pain intensity in the uninjured leg, pain intensity in the injured leg, magnitude of capability, and pain accommodation, controlling for other demographic and injury-related factors.

RESULTS

Greater pain intensity in the uninjured leg (regression coefficient [RC] 0.09 [95% CI 0.02 to 0.16]; p < 0.01) was moderately associated with more unhelpful thinking regarding symptoms. This indicates that for every one-unit increase in unhelpful thinking regarding symptoms on the 17-point scale we used to measure pain catastrophizing, pain intensity in the uninjured leg increases by 0.94 points on the 11-point scale that we used to measure pain intensity, holding all other independent variables constant. Greater pain intensity in the injured leg (RC 0.18 [95% CI 0.08 to 0.27]; p < 0.01) was modestly associated with more unhelpful thinking regarding symptoms. Greater pain accommodation (RC -0.25 [95% CI -0.38 to -0.12]; p < 0.01) was modestly associated with less unhelpful thinking regarding symptoms. Greater magnitude of capability was not independently associated with less unhelpful thinking regarding symptoms.

CONCLUSION

A patient's report of concerns regarding pain in the uninjured limb (such as, "I'm overcompensating for the pain in my other leg") can be considered an indicator of unhelpful thinking regarding symptoms. Orthopaedic surgeons can use such reports to recognize unhelpful thinking and begin guiding patients toward healthier thoughts and behaviors.

Prospective randomized controlled trial comparing the effect of Monocryl versus nylon sutures on patient- and observer-assessed outcomes following carpal tunnel surgery

Controversy remains regarding the optimal technique and suture type for wound closure after carpal tunnel surgery. Adult patients undergoing open carpal tunnel release were prospectively randomized to receive either interrupted, buried Monocryl sutures or traditional nylon horizontal mattress sutures for their wound closures. At the 2-week and 6-week postoperative visits, Patient and Observer Scar Assessment Scale questionnaires were completed. At 2 weeks, patients and observers had a significantly better opinion of incisions closed with Monocryl. By 6 weeks, neither patients nor observers found a difference between suture types in any category. Scars of wounds closed with Monocryl did not change appreciably in appearance between 2 and 6 weeks. However, patients and observers noted significant improvement in scar appearance in the nylon group over time. Monocryl suture represents an effective method for carpal tunnel closure that leads to improved patient- and observer-reported outcome scores in the early postoperative period compared with nylon.Level of evidence: II.

Outcomes of Reverse Total Shoulder Arthroplasty for Proximal Humerus Fracture Versus Rotator Cuff Arthropathy

INTRODUCTION

Reverse total shoulder arthroplasty (RSA) is used to treat a variety of shoulder-related pathologies. This study compared medium-term clinical outcomes of less than 10-year follow-up in patients treated with RSA for proximal humerus fracture (PHF) versus rotator cuff arthropathy (RCA).

METHODS

This retrospective review was conducted at two tertiary care centers, in which self-reported clinical outcomes were assessed using four validated instruments, that is, American Shoulder and Elbow Society (ASES) score, Shoulder Pain and Disability Index (SPADI), visual analog scale (VAS), and shoulder subjective value (SSV). Statistical analyses were performed using linear or logistic regression with generalized estimating equations.

RESULTS

Of the 189 patients included in this study, 70 were treated for fracture and 119 for RCA. At a mean postoperative follow-up of 6.4 years, the means were 79.7 for ASES score, 20.8 for SPADI-Total, 0.8 for VAS, and 77.1 for SSV. After adjusting models for covariates, there was no significant difference in average SSV (P = 0.7), VAS (P = 0.7) or SPADI-Pain (P = 0.2) between PHF and RCA cohorts; however, the RCA cohort reported significantly better outcomes in ASES scores (P = 0.002), SPADI-Disability (P < 0.0001), and SPADI-Total (P = 0.0001).

DISCUSSION

Patients with RCA and PHF treated with RSA achieved similar medium-term outcomes in several domains, particularly postoperative pain levels; however, patients with PHF reported greater perceived disability. RSA is an effective pain-controlling procedure, but patients may have variable functional outcomes based on the indication for surgery.

The impact of psychological factors on outcome after salvage surgery for wrist osteoarthritis

This prospective longitudinal study of 80 patients analysed the effect of preoperative pain catastrophizing, anxiety, depression and sense of coherence on the Disabilities of the Arm, Shoulder and Hand, Patient-Rated Wrist Evaluation, quality of life, grip strength and range of motion during the first year after salvage surgery for wrist osteoarthritis. Generalized estimating equations were used to analyse the effect of the psychological factors on the outcome variables. Pain catastrophizing or a tendency for anxiety preoperatively had a strong negative impact on postoperative Disabilities of the Arm, Shoulder and Hand and Patient-Rated Wrist Evaluation. Anxiety also predicted a lower postoperative quality of life, whereas pain catastrophizing had a negative impact on grip strength. Sense of coherence did not influence the outcome.Level of evidence: II.
