Background Mindfulness-based interventions are useful in reducing psychologic distress and pain intensity in patients with chronic pain. However, most mindfulness-based interventions are resource-intensive, lengthy, and not feasible for busy orthopaedic surgical practices. Questions/purposes The purpose of this study was to determine if a 60-second personalized mindfulness-based video exercise is (1) associated with improved pain intensity, emotional distress, and state anxiety compared with an attention placebo control (a time-matched educational pamphlet about pain and stress); and (2) feasible and acceptable for patients with upper extremity injury in an orthopaedic practice. Methods This was a single-center, single-blind randomized controlled trial of the mindfulness-based video exercise (60 seconds duration, free online) versus an attention placebo control (an educational pamphlet about pain and stress presented to patients to read over 60 seconds). One hundred forty-nine patients presenting for a new or followup appointment at the office of one of two orthopaedic hand and upper extremity outpatient surgical practices at an urban academic hospital were invited to participate between September 2016 and December 2016. Of 149 patients screened, 125 patients were randomized and completed a demographic questionnaire, the Numeric Rating Scale to assess pain intensity, the State Anxiety subscale of the State Trait Anxiety Inventory to assess state anxiety, and Emotion Thermometers to assess anxiety, anger, and depression before and after the interventions. Postintervention, patients also completed the Client Satisfaction Questionnaire Scale-3 to assess the acceptability. A mean score of 21 or higher is considered acceptable. Feasibility was determined based on number of patients approached who refused participation. The intervention was defined as feasible if refusal rate was lower than 25%. Analysis of covariance was used to test comparative improved pain intensity on the NRS, psychologic distress on the Emotion Thermometers, and state anxiety on the State Anxiety Subscale of the State Trait Anxiety Index after controlling for respective baseline scores. A 1-point minimal clinically important difference (MCID) was used on the NRS for pain intensity. Results Adjusted for the baseline means, compared with patients who received the attention placebo control, patients who participated in the mindfulness-based video exercise demonstrated improved pain intensity (mindfulness-based video exercise: 3.03 ± 0.12; control: 3.49 ± 0.12; mean difference: 0.46 [0.12-0.80]; p = 0.008); state anxiety (mindfulness-based video exercise: 32.35 ± 0.59; control: 35.29 ± 0.59; mean difference: 2.94 [1.29-4.59]; p = 0.001); anxiety symptoms (mindfulness-based video exercise: 1.49 ± 0.19; control: 2.10 ± 0.19; mean difference: 0.61 [0.08-1.14]; p = 0.024); depression (mindfulness-based video exercise: 1.03 ± 0.10; control: 1.47 ± 0.11; mean difference: 0.44 [0.15-0.73]; p = 0.004); and anger (mindfulness-based video exercise: 0.76 ± 0.12; control: 1.36 ± 0.12; mean difference: 0.60 [0.26-0.94]; p = 0.001). However, the observed differences in pain intensity were below 1 point on the NRS, which is the MCID established in patients with chronic pain. No MCID is available for the other measures. The mindfulness-based video exercise was feasible based on a dropout rate of 0%, and acceptability reached the medium range with similar scores in both groups (mindfulness-based video exercise: 20.70 ± 5.48; control: 20.52 ± 6.42). Conclusions A 60-second mindfulness-based video exercise is feasible to implement and acceptable to patients in busy orthopaedic practices. This video exercise is also effective in improving momentary pain, anxiety, depression, and anger in this population, but it is unclear whether these improved pain and distress levels are meaningful to patients who present with low levels of pain and psychologic distress. Future studies should seek to discern whether the improved pain and distress levels we observed are clinically important or whether the intervention delivers larger effects in subgroups of patients experiencing greater pain intensity and if the improved pain and distress levels are durable. Such studies might also assess cost-effectiveness, because this mindfulness-based tool takes little time and few resources to use, and the effects and durability of multiple sessions of a mindfulness-based video exercise.

Background: This study addresses the prevalence of discrete pathophysiology accounting for patients’ symptoms during diagnostic wrist arthroscopy in individuals with wrist pain without a specific preoperative diagnosis. Secondarily, we determined the number and type of surgeries subsequent to diagnostic wrist arthroscopy. Methods: Between January 2000 and January 2015, 135 diagnostic wrist arthroscopies were performed by 12 surgeons in 3 urban academic hospitals. We recorded the diagnostic findings of diagnostic wrist arthroscopy and any subsequent surgeries. Results: One hundred and five patients had synovitis or a normal wrist (78%), 17 had likely age-appropriate changes (eg, central triangular fibrocartilage complex defects scapholunate changes) (13%), 8 (6%) were given uncommon diagnoses, and 5 (4%) had osteochondral defects. Sixteen patients (12%) had subsequent wrist surgery: 2 were for adverse events, 2 were carpal tunnel releases, and 12 were other surgeries. Conclusion: Diagnostic arthroscopy performed in the setting of an unclear preoperative diagnosis yielded limited diagnostic benefit.

Background: Grip strength is a performance-based measure of upper extremity function that might be influenced by priming (the influence of a response to a stimulus by exposure to another stimulus). This study addressed the influence of questionnaire content on performance measurements such as grip strength between patients who complete the standard Pain Catastrophizing Scale (PCS) compared with patients who complete a positively adjusted PCS. Methods: Between June 2015 and August 2015, we enrolled 122 patients who presented to 3 hand surgeons at 3 outpatient offices. They were randomized to 2 groups: the control group, which completed the PCS, and the intervention group, which completed a positively phrased version of the PCS. Before and after completion of the questionnaire, we measured each patient’s grip strength 3 times by alternating between hands. Two patients were excluded after participation. We calculated both the preintervention and postintervention mean and maximum grip strengths. Results: There was no significant difference between groups on mean or maximum grip strength before completion of the questionnaires. There was a greater improvement in mean grip strength of both hands in the intervention group compared with the PCS group. This improvement was statistically significant in the affected hand. The maximum grip strength showed a statistically significant greater improvement in both hands in the positive PCS group compared with the control group. Conclusions: Positive priming through a questionnaire leads to an increase in mean and maximum grip strength when compared with the standard questionnaire that uses negative terms rather than positive.

Background The dorsal lunate facet fragment represents part of a complex articular injury of the distal radius and is challenging to reduce through a standard volar approach. We propose reduction through a standard volar approach and intraoperative dorsal lunate facet reduction using a bone forceps. To evaluate the postoperative reduction, we used computed tomography (CT) scan. Methods We retrospectively included 60 patients with a median follow‐up of 44 weeks. Fracture reduction was evaluated using pre‐ and direct postoperative CT scans of the wrist, measuring the articular gap and step of the sigmoid notch. The range of motion was evaluated clinically by the treating physician. Bivariate analysis was performed to compare pre‐ and postoperative radiographic measurements and to compare wrist range of motion. Results When comparing the injured with the uninjured wrist, there was a significant difference in flexion, extension, pronation, and supination. In 87% of the patients, there was complete radiographic reduction of the fracture. Conclusion This study shows that dorsal ulnar lunate facet fracture fragments in distal radius fractures can be reduced through a standard volar approach with the help of an intraoperative bone reduction forceps. Using wrist CT, we showed that 87% of the patients with a dorsal ulnar lunate facet fragment had a postoperative articular step or gap of <1 mm. Level of Evidence: This is a level IV, therapeutic study.

Background Radiographic diagnosis of scapholunate ligament injury (SLI) in the setting of distal radius fractures (DRFs) is challenging. It remains unclear to what extent radiographic diagnosis of SLI by a radiologist influences surgical decision‐making regarding treatment of SLI. Purpose We aimed to (1) identify the number of times that concerns for the possibility of concurrent SLI in the setting of a DRF had been raised by the radiologists, (2) identify how often the radiologists diagnosis was confirmed by the treating surgeon, and (3) how many of the patients with a radiographic concern for SLI by the radiologist received operative treatment for the SLI. Patients and Methods Based on Current Procedural Terminology codes, we identified 2,923 patients that were operatively treated for their DRF in 1 of 3 participating institutions in an urban city in the United States. We reviewed the medical charts of 654 patients who had a mention of scapholunate ligament (SL) distance in their radiography, surgery, or clinical notes. We then measured the SL distance and recorded patient, diagnosis, and treatment characteristics of all these patients. Results A total of 200 out of 2,923 patients (6.8%) received a radiological diagnosis of SLI. In seven of these patients (3.5%), the surgeon confirmed the diagnosis of the radiologist. Four patients (2%) had operative repair of their SLI. Conclusion Radiologists demonstrate a low threshold to identify SLI in the setting of DRFs, while the number of SLIs identified by the treating surgeon is a remarkably smaller number. Level of Evidence Level II, prognostic study.

Objective Closed reduction and percutaneous pinning (CRPP) is losing popularity as a treatment modality for distal radius fractures. However, in select cases, CRPP may have advantages relative to open reduction and internal reduction. We aimed to retrospectively assess the outcomes after CRPP for the treatment of distal radius fractures. Study Design This is a retrospective cohort study. Methods We used billing records to identify all skeletally mature patients with a distal radius fracture who were treated with CRPP by a single surgeon at a level I trauma center in an urban city in the United States. We assessed the medical charts and recorded demographics, trauma and treatment characteristics, radiographic characteristics, and outcomes. Results All patients had a good or excellent range of motion regarding forearm rotation, and almost 80% had good or excellent range of motion regarding flexion or extension of their wrist. One patient had a concern for pin tract infection, and one had subcutaneous migration of a pin, which were both treated by pin removal. Conclusion CRPP is a good option in patients with few and sizeable fracture fragments in patients with a distal radius fracture, and it should be considered as an effective tool to restore radiographic parameters and functional outcomes.

Ulnar Neck Fractures Associated with Distal Radius Fractures

Sezai Özkan; Stefan F. Fischerauer; Thomas J.M. Kootstra; Femke M.A.P. Claessen; David Ring

Abstract Background There is little published data to guide management of ulnar neck fractures associated with fractures of the distal radius. Purpose As unplanned surgery usually reflects adverse events and this injury combination is relatively uncommon, we used a large database to study the incidence of unplanned surgeries after surgical and nonsurgical treatment of distal metaphyseal ulna fractures associated with a distal radius fracture and identify factors associated with these unplanned surgeries. Patients and Methods We identified 277 patients with an ulnar neck fracture associated with a distal radius fracture. Fifty‐six (20%) ulnar neck fractures were initially treated operatively and six of them (11%) had a second, unplanned surgery. Of the 221 initially nonoperatively treated fractures, only one (0.45%) had a subsequent unplanned surgery that seemed unrelated to the fracture (ulnar nerve neurolysis). Results Bivariate analysis showed that younger age, open fracture, multifragmentary fractures, and initial operative treatment of the ulnar neck fracture were significantly associated with unplanned surgery. A multivariable analysis was not feasible due to the small number of unplanned surgeries. Conclusion Eighty percent of ulnar neck fractures associated with a fracture of the distal radius was treated nonoperatively in our region, and subsequent surgery for problems was very uncommon. Operative treatment and fracture complexity were associated with unplanned surgery, which reflected some measure of injury severity, technical inadequacy, and inherent problems associated with surgery. Level of Evidence Level II, prognostic study.
