Evaluation and Management of Sleep Disorders in the Hand Surgery Patient

Carpal tunnel decompression: a comparison of elderly and younger patients' sleep quality

The current study was conducted to evaluate sleep disturbances by age group in patients who underwent carpal tunnel decompression (CTD). Individuals who applied to the orthopedic outpatient clinic and had CTD between 2018 and 2022 had their medical records reviewed. Pre-operative data included patient demographics and the Pittsburgh Sleep Quality Index (PSQI). All post-surgery patients who returned for suture removal were clinically evaluated. Patients were requested to return for re-scoring on the PSQI 6 months after CTD. The cases' average age was 56.44±9.37 years. The study divided its subjects into two age ranges: those between the ages of 45 and 60 (82.2%) (Group1) and those between the ages of 70 and 85 (17.8%) (Group 2). The PSQI values of Group 1 were found to be significantly lower than Group 2. Preoperative PSQI levels were compared to post-op values at 2 weeks and 6 months, and both measurements decreased significantly. Sleep quality improved in all patient groups, regardless of their age, following CTD. Elderly patients had delayed improvements in sleep quality following CTD. The PSQI was effective in determining improvement following CTD, particularly in younger patients, and the progress remained for 6 months.

Improvement of Sleep Quality after Surgical Decompression in Carpal Tunnel Syndrome

Background Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy which can cause severe sleep disturbance. Carpal tunnel release (CTR) is a choice for severe cases, which has shown to improve sleep quality, but the available evidence is limited. This study aimed to investigate the impact of CTR on sleep quality and hand symptoms and functions in patients with CTS.

Methods This was a prospective study in 2019–2020 on patients with CTS and poor sleep quality undergoing CTR. Patients were evaluated before and at 1, 3, and 12 months after CTR by the Pittsburgh sleep quality index (PSQI) and Boston carpal tunnel syndrome questionnaires.

Results There were 33 patients with 27 females (82%) and a median age of 51 years. The median time of CTS diagnosis and having sleep disorder before CTR were 12 and 6 months, respectively. The outcomes significantly improved after CTR, with the median PSQI and Boston symptom and function scores reduced from 12, 33, and 23 before CTR to 9, 14, and 11 at 1 month; 7, 13, and 9 at 3 months; and 1, 11, and 8 at 12 months postoperatively, respectively. The correlations between the PSQI and Boston symptom and function scores were > 0.6 at all time-points.

Conclusions Surgical decompression significantly improves sleep quality and the hand symptoms and functions in patients with CTS. Long-term evaluations are lacking and thus are required in future studies.

Persistent sleep disturbance after spine surgery is associated with failure to achieve meaningful improvements in pain and health-related quality of life

BACKGROUND CONTEXT

Little is known about the effects of sleep disturbance (SD) on clinical outcomes after spine surgery.

PURPOSE

To determine the (1) prevalence of SD among patients presenting for spine surgery at an academic medical center; (2) correlations between SD and health-related quality of life (HRQoL) scores; and (3) associations between postoperative SD resolution and short-term HRQoL.

STUDY DESIGN

Retrospective review of prospectively collected data.

PATIENT SAMPLE

We included 508 adults undergoing spine surgery at 1 academic center between December 2014 and January 2018.

OUTCOME MEASURES

Participants completed the Oswestry Disability Index (ODI) or Neck Disability Index (NDI) and Patient Reported Outcome Measurement System (PROMIS-29) questionnaire preoperatively, during the immediate postoperative period (6-12 weeks), and at 6, 12, and 24 months after surgery.

METHODS

Using preoperative PROMIS SD scores, we grouped participants as having no sleep disturbance (score <55), mild disturbance (score, 55-60), moderate disturbance (score 60-70), or severe disturbance (score, 70). For the final analysis, we collapsed these categories into no/mild and moderate/severe. Pearson correlation tests were used to assess correlations between SD and HRQoL measures. Regression analysis (adjusting for age, sex, comorbidities, current opioid use, and occurrence of complications) was used to estimate the effect of postoperative resolved or continuing SD on HRQoL scores and the likelihood of achieving clinically meaningful improvements in HRQoL. Alpha = 0.05.

RESULTS

Preoperative SD was reported by 127 participants (25%). SD was significantly correlated with worse ODI and/or NDI values and worse scores in all PROMIS health domains (all, p<.001). At the immediate postoperative assessment, SD had resolved in 80 of 127 participants (63%). Compared with participants who reported no preoperative SD, those with ongoing SD were significantly less likely to achieve clinically meaningful improvements in Pain Interference (odds ratio [OR], 0.49; 95% confidence interval [CI], 0.28, 0.84), Physical Function (OR, 0.32; 95% CI, 0.13, 0.82), and Satisfaction with Participation in Social Roles (OR, 0.57; 95% CI, 0.37, 0.80).

CONCLUSION

One-quarter of spine surgery patients reported preoperative SD of at least moderate severity. Poor preoperative sleep quality and ongoing postoperative sleep disturbance were significantly associated with worse scores on several HRQoL measures. These results highlight the importance of addressing patients' sleep disturbance both before and after surgery.

Awan H. Early Postoperative Improvement in Sleep and Pain After Carpal Tunnel Release

Background: Carpal tunnel syndrome (CTS) is the most common compressive neuropathy of the upper extremity. We sought to assess the subjective improvement in preoperative symptoms related to CTS, particularly those affecting sleep, and describe opioid consumption postoperatively. Methods: All patients undergoing primary carpal tunnel release (CTR) for electromyographically proven CTS were studied prospectively. All procedures were performed by hand surgery fellowship-trained adult orthopedic and plastic surgeons in the outpatient setting. Patients underwent either endoscopic or open CTR from June 2017 to December 2017. Outcomes assessed were pre- and postoperative Quick Disabilities of Arm, Shoulder and Hand (QuickDASH), visual analog scale (VAS), and Pittsburgh Sleep Quality Index (PSQI) scores as well as postoperative pain control. Results: Sixty-one patients were enrolled. At 2 weeks, all showed significant (P < .05) improvement in QuickDASH scores. At 6 weeks, 40 patients were available for follow-up. When compared with preoperative scores, QuickDASH (51 vs 24.5; P < .05), VAS (6.7 vs 2.9; P < .05), and PSQI (10.4 vs 6.4; P < .05) scores continued to improve when compared with preoperative scores. At 2-week follow-up, 39 patients responded to the question, "How soon after your carpal tunnel surgery did you notice an improvement in your sleep?" Seventeen patients (43.6%) reported they had improvement in sleep within 24 hours, 12 patients (30.8%) reported improvement between 2 and 3 days postoperatively, 8 patients (20.5%) reported improvement between 4 and 5 days postoperatively, and 2 patients (5.1%) reported improvement between 6 and 7 days postoperatively. Conclusions: The present study demonstrates rapid and sustained improvement in sleep quality and function following CTR.

Association between upper extremity dysfunction and sleep disturbance in an elderly general population

Objective

Several upper extremity disorders are associated with sleep disturbance in patient populations. This study evaluated the relation between self-assessment of upper extremity function and sleep disturbance in an elderly general population.

Methods

A total of 159 participants (56 men, 103 women, 38-88 years old, mean age of 66.4 years) completed a self-administered questionnaire including items for sex, weight, height, and dominant hand. Upper extremity dysfunction was investigated using Quick Disabilities of the Arm, Shoulder, and Hand of the Japanese Society for Surgery of the Hand. The sleep disturbance severity was evaluated using a Japanese version of the Athens Insomnia Scale. Quality of life was assessed using the EuroQol-5-dimension-3-level, Japanese version. We measured the bilateral hand grip as an indicator of hand muscle function. Statistical tests were applied to clarify the association between upper extremity dysfunction and screening results for sleep disturbance.

Results

Of 159 participants, 45 (28.3%) had sleep disturbance as assessed using Japanese version of the Athens Insomnia Scale (11 men and 34 women; mean age of 68.1 years). Japanese version of the Athens Insomnia Scale scores correlated with the EuroQol index; EuroQol visual analog scale; and Quick Disabilities of the Arm, Shoulder, and Hand scores. The Quick Disabilities of the Arm, Shoulder, and Hand score and dominant grip strength of the participants with sleep disturbance were significantly higher than those of the no sleep disturbance group. The EuroQol index score and visual analog scale of those reporting a sleep disturbance were significantly lower than those of the no sleep disturbance group.

Conclusion

Self-administered upper extremity health condition as assessed using Quick Disabilities of the Arm, Shoulder, and Hand correlated with sleep disturbance. Our results suggest a link between upper extremity conditions and sleep disturbance.

Relationship between electrodiagnostic findings and sleep disturbance in carpal tunnel syndrome: A controlled objective and subjective study

Objective

This controlled objective and subjective study aimed to evaluate the relationship between insomnia severity and electrodiagnostic findings in patients with carpal tunnel syndrome (CTS).

Methods

Twenty-one patients with an established clinical and electrodiagnostic diagnosis of CTS before surgery were included. Sleep characteristics were monitored objectively over 4 to 9 nights by means of actigraphy. On the following morning, participants completed a sleep log that conveyed their subjective impressions of how they had slept. All patients also completed the Insomnia Severity Index questionnaire. The correlation of these findings with patients’ motor latency and sensory latency was evaluated using Spearman correlation analysis.

Results

We found no correlation between sensory or motor latencies and all sleep measures.

Conclusion

Electrodiagnostic findings and sleep severity in patients with CTS appear to be independent measures, and they do not correlate with each other.

Prospective evaluation of sleep improvement after cubital tunnel decompression surgery

BACKGROUND

Compromised sleep is a known phenomenon with compressive neuropathies such as carpal tunnel syndrome. However, the prevalence of sleep disturbance with cubital tunnel syndrome (CuTS) and the effect on sleep after ulnar nerve decompression are not well understood. We hypothesized that CuTS results in sleep disturbances and that decompression surgery would result in improvement in overall sleep quality.

METHODS

Consecutive patients with electrodiagnostic-proven CuTS indicated for decompression were prospectively enrolled. Demographic data, McGowan grade, electrodiagnostic (electromyography) severity, visual analog scale pain score, the 11-item version of the Disabilities of the Arm, Shoulder and Hand questionnaire, and the Insomnia Severity Index scale data were collected preoperatively and at 2 weeks and 3 months postoperatively.

RESULTS

There were 145 patients enrolled, with 97% available at 2 weeks and 72% available at the final 3-month follow-up. Surgical decompression procedures consisted of 102 in situ releases and 43 transpositions. The average preoperative Insomnia Severity Index score for the entire cohort was 10.7, above the threshold for a diagnosis of insomnia, which subsequently improved to 4.1 by final follow-up postoperatively, consistent with resolution of the insomnia. There was no difference in the extent of sleep improvement between in situ decompression and transposition. Similarly, electromyography severity and McGowan grade also did not appear to significantly affect the extent of sleep improvement.

CONCLUSION

CuTS decompression surgery, irrespective of surgical type and preoperative severity, resulted in improvement in sleep by the 3 month postoperative visit.

Preferences in Sleep Position Correlate With Nighttime Paresthesias in Healthy People Without Carpal Tunnel Syndrome

BACKGROUND

Carpal tunnel syndrome has been associated with sleep position preferences. The aim of this study is to assess self-reported nocturnal paresthesias and sleeping position in participants with and without carpal tunnel syndrome diagnosis to further clinical knowledge for preventive and therapeutic interventions.

METHODS

A cross-sectional survey study of 396 participants was performed in young adults, healthy volunteers, and a patient population. Participants were surveyed on risk factors for carpal tunnel syndrome, nocturnal paresthesias, and sleep preferences. Binary logistic regression analysis was performed comparing participants with rare and frequent nocturnal paresthesias. Subanalyses for participants without carpal tunnel syndrome under and over 21 years of age were performed on all factors significantly associated with subclinical compression neuropathy in the overall population.

RESULTS

Thirty-three percent of the study population experienced nocturnal paresthesias at least weekly. Increased body mass index ( P < .001) and sleeping with the wrist flexed ( P = .030) were associated with a higher frequency of nocturnal paresthesias. Side sleeping was associated with less frequent nocturnal symptoms ( P = .003). In participants without carpal tunnel syndrome, subgroup analysis illustrated a relationship between nocturnal paresthesias and wrist position. In participants with carpal tunnel syndrome, sleeping on the side had a significantly reduced frequency of nocturnal paresthesias.

CONCLUSION

This study illustrates nocturnal paresthesias in people without history of carpal tunnel syndrome including people younger than previously reported. In healthy patients with upper extremity subclinical compression neuropathy, sleep position modification may be a useful intervention to reduce the frequency of nocturnal symptoms prior to developing carpal tunnel syndrome.

Obstructive sleep apnea affects complication rates following knee arthroscopy but use of continuous positive airway pressure is not protective against complications

PURPOSE

Obstructive sleep apnea (OSA) has not been studied as a risk factor for complications following knee arthroscopy. The goals of this study were to: (1) compare complication rates after knee arthroscopy between patients with and without OSA and (2) evaluate whether continuous positive airway pressure (CPAP) mitigated complication rates.

METHODS

A national private insurance database was queried for patients undergoing simple knee arthroscopy from 2007 to 2016. Patients with a diagnosis of OSA were then identified using ICD-9/10 codes. Patients with OSA were then subdivided into cohorts with and without a billing code for a CPAP device. Adverse events within 30 days postoperatively related to OSA were then assessed in all groups: (1) emergency room (ER) visit, (2) hospital admission, (3) pulmonary embolism (PE), (4) myocardial infarction, (5) respiratory arrest and (6) in-hospital mortality within 6 months postoperatively. Adverse event rates were compared between the control and study groups using a multivariable regression analysis.

RESULTS

97,036 patients underwent simple knee arthroscopy with 8656 patients having a diagnosis of OSA. Of these, 3820 (44%) had orders for CPAP machines. After controlling for confounders, patients with OSA had significantly higher risk of ER visits, PE and respiratory arrest compared to controls (p < 0.05). The majority of these significant findings persisted regardless of CPAP use. There were no significant differences in complication rates between OSA patients with and without CPAP orders.

CONCLUSIONS

OSA appears to be independently associated with a higher risk for ER visits, PE and respiratory arrest following knee arthroscopy after controlling for demographic and comorbidity confounders. An order for CPAP was not associated with a significant reduction the risk for these complications. CPAP noncompliance may not be as important a factor when risk stratifying patients undergoing ambulatory knee arthroscopy compared to more significant medical comorbidities.

Sleep disturbance and response to surgical decompression in patients with carpal tunnel syndrome: a prospective randomized pilot comparison of open versus endoscopic release

BACKGROUND

Sleep disturbance is a common complaint of patients with carpal tunnel syndrome (CTS). While carpal tunnel release (CTR) surgery has been shown to relieve subjective sleep-related complaints, data is lacking on the global effect on sleep using validated sleep measures. Additionally, it is not known if open (OCTR) or endoscopic release (ECTR) produce differing degrees of sleep-symptom relief.

METHODS

Sixty patients were randomly allocated to undergo either OCTR (n=30) or ECTR (n=30) surgery. Forty-three (71.7%) of the patients were female, and mean age of all patients was 49.4 years (range, 35-78). Prior to surgery, patients were administered three baseline self-reported outcome measures: the Pittsburgh Sleep Quality Index (PQSI), the Insomnia Severity Scale (ISI) and the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) survey, which were subsequently administered at three postoperative time points: 1-2 weeks, 4-6 weeks and 6-12 months.

RESULTS

All 60 patients experienced significant improvements in the three outcome scores by their first postoperative visit compared to preoperatively. ECTR provided superior improvement to OCTR at the first postoperative visit for ISI (P=0.006) and PSQI (P=0.016), and at the second visit for PSQI (P=0.0038). There were no significant differences between the two groups for the QuickDASH at any time points, or for the ISI/PSQI at the final follow-up.

CONCLUSION

Endoscopic and open CTR both improve sleep symptoms postoperatively in the short-term which is sustained for 6-12 months, although endoscopic CTR does so more rapidly.
