Background: Rates of opioid addiction and overdose continue to climb in the United States, increasing pressure on prescribers to identify solutions to decrease postoperative opioid consumption. Hand and upper extremity surgeries are high-volume surgeries with a predilection for inadvertent overprescribing. Recent investigations have shown that preoperative opioid counseling may decrease postoperative opioid consumption. In order to test this hypothesis, a prospective randomized trial was undertaken to determine the effect of preoperative opioid counseling on postoperative opioid consumption. Methods: Eligible patients undergoing outpatient upper extremity surgery were randomized to either receive preoperative opioid counseling or to receive no counseling. Surgeons were blinded to their patient's counseling status. Preoperatively, patient demographics, surgical and prescription details were recorded. Postoperatively, patients' pain experience including opioid consumption, pain levels, and satisfaction was recorded. Results: There were 131 total patients enrolled, with 62 in the counseling group and 69 in the control group. Patients receiving counseling consumed 11.8 pills compared to 17.4 pills in the control group (P = .007), which translated to 93.7 Morphine Equivalent Units (MEU) in the counseling group compared to 143.2 MEU in the control group (P = .01). There was no difference in pain scores at any time point between groups. Among all study patients a total of 3767 opioid pills were prescribed with approximately 50% left unused. Conclusion: Patients receiving preoperative counseling consumed significantly fewer opioids postoperatively. Inadvertant overprescribing remains high. Routine use of preoperative counseling should be implemented along with prescribing fewer opioids overall to prevent overprescribing.

Background: There is a paucity of literature exploring the epidemiology of finger infections presenting to emergency departments (EDs) on a national scale. The purpose of this study was to determine the national incidence of and risk factors for finger infections. Methods: Finger infections presenting to EDs between 2012 and 2016 were identified in the National Electronic Injury Surveillance System database. Finger infections were characterized by mechanism and type, with subanalyses for sex, race, and age. Results: Over this 5-year period, finger infections accounted for 80 519 visits to EDs in the United States. The annual incidence increased significantly from 4.4 per 100 000 person-years in 2012 to 6.2 in 2016. The 3 most common causes of finger infections were nail manicuring tools, knives, and doors. The most common diagnosis was finger cellulitis (46.3%). Significantly more men developed finger infections than women (relative risk of 1.4). The highest overall incidence was observed in 40- to 59-year-old men (7.8 per 100 000 person-years). Tenosynovitis resulted in the largest proportion of admissions (25%). Conclusions: We have demonstrated a rising incidence of finger infections presenting to EDs, with 40- to 59-year-old patients most at risk. The most common mechanism was the use of nail manicuring tools, such as nail clippers. Patient education may decrease finger infection incidence from these activities, and early detection of finger infections may be crucial to minimizing hospital admissions and invasive treatments.

Background: Peripheral nerve injuries may result in pain, disability, and decreased quality of life (QoL). Pain is an incompletely understood experience and is associated with emotional and behavioral qualities. We hypothesized that pain following peripheral nerve surgery could be predicted by changes in emotions or QoL postoperatively. Methods: Using prospectively collected data, a retrospective study design was used to evaluate the relationships among pain, QoL, and psychosocial factors in patients who underwent peripheral nerve surgery. Patients completed questionnaires rating pain; impact of pain on QoL, sadness, depression, frustration, anger, and hopefulness before surgery; and each postoperative follow-up visit. Multilevel modeling was used to assess the concurrent and lagged relationships between pain and psychosocial factors. Results: Increased pain was concurrently associated with decreased hopefulness (P = .001) and increased the impact on QoL, sadness, depression, and anger (P < .001). In lagged analyses, the impact on QoL and anger prospectively predicted pain (P < .001 and P = .02, respectively). Pain predicted subsequent scores of QoL, sadness, depression, anger, and hopefulness (P < .01). Having an upper limb nerve injury and self-report of "no comment for childhood trauma" were predictors of postsurgical pain. Conclusion: Psychosocial measures and pain are reciprocally related among patients who underwent surgery for peripheral nerve injuries or compression. Our study provides evidence of the important relationships among psychosocial factors, pain, and outcome and identifies treatment targets following nerve surgery.

Background: Digital nerves will experience tension under normal daily activities, and understanding the amount of tension experienced in these nerves relates directly to the necessary strength in nerve repairs. To begin quantification of tension, the tension borne by the median and digital nerves in cadaveric hands was quantified under conditions of finger hyperextension, nerve distraction, and finger flexion. Methods: Five cadaveric hands were mounted in a special fixture that allowed finger hyperextension and flexion and could apply known distractions while the tension borne by each digital nerve was measured. Sequential dissection exposed the digital nerves so that measurements of tension in the median, common, and proper digital nerves were conducted with finger hyperextension, nerve distraction, and finger flexion. Results: Metacarpophalangeal (MCP) hyperextension of 30° created mean nerve tensions up to 0.64 N, 5 mm of nerve distraction created mean nerve tensions up to 1.23 N, and 90° of MCP flexion relieved up to a mean of 1.18 N of nerve tension. Conclusions: In situ tension is present in the median and digital nerves with digital motion. Finger hyperextension and nerve distraction produce tension, whereas finger flexion reduces tension. Existing nerve repairs are strong enough to withstand in situ nerve tensions produced by reasonable digital motion if the original nerve length is present.

Background: Although the diagnosis of thoracic outlet syndrome (TOS) is often missed, outcomes from surgical intervention significantly improve patient satisfaction. This article seeks to highlight patient characteristics, intraoperative findings, and both short and long-term outcomes of thoracic outlet decompression in the adolescent population. Methods: A retrospective chart review of patients between the ages of 13 and 21 years with a clinical diagnosis of neurogenic thoracic outlet syndrome (NTOS) who were treated surgically between 2000 and 2015 was performed. Data points including preoperative patient characteristics and intraoperative findings were collected. In addition, patient-reported outcome scores, including Visual Analog Scale (VAS), Single Assessment Numeric Evaluation (SANE), Quick Disabilities of the Arm, Shoulder, and Hand (QuickDASH) questionnaire, Cervical Brachial Symptom Questionnaire (CBSQ), and NTOS index, were obtained for a cohort of patients with follow-up ranging from 2 to 15 years. Results: The study population consisted of 54 patients involving 61 extremities. The most common procedures included neurolysis of the supraclavicular brachial plexus (60, 98.4%), anterior scalenectomy (59, 96.7%), and middle scalenectomy (54, 88.5%). First rib resection (FRR) was performed in 28 patients (45.9%). Long-term outcomes were collected for 24 (44%) of 54 patients with an average follow-up of 69.5 months (range, 24-180 months). The average VAS improved from 7.5 preoperatively to 1.8 postoperatively. The average SANE increased from 28.9 preoperatively to 85.4 postoperatively. The average postoperative scores were 11.4 for the QuickDASH, 27.4 for the CBSQ, and 17.2 for the NTOS index. Subgroup analysis of patients having FRR (28, 45.9%) demonstrated no difference in clinical outcome measures compared with patients who did not have FRR. Conclusion: Surgical treatment of NTOS in adolescent patients has favorable intermediate and long-term outcomes.

Introduction: Carpal tunnel syndrome and ulnar neuropathy are such common maladies affecting the upper extremties that they often become the default diagnosis when patients complain of numbness, pain, or weakness of the hands. While often correct, there are a number of other conditions that can also cause sensory or motor loss of the hands, which should be considered when appropriate, as they can mimic upper extremity entrapment syndromes. Methods: In this review, we will discuss such mimics, including Charcot-Marie-Tooth disease, multifocal motor neuropathy, hereditary neuropathy with pressure palsies, mononeuropathy multiplex, Lewis-Sumner syndrome, brachial plexitis (Parsonage-Turner syndrome), myotonic dystrophy, inclusion body myopathy, and distal myopathy of Welander. We will discuss the clinical presentation, as well as diagnostic testing, treatment (if available), and prognosis. Conclusion: The objective is to provide a differential diagnosis for those patients who do not fit well clinically or respond to usual therapy for entrapment neuropathy of the upper extremities.

Background: To present a retrospective study on the outcomes of a modified version of suture suspension arthroplasty with trapeziectomy on patients with thumb basal joint arthritis and to evaluate the relationship between the degree of subsidence and functional outcome. Methods: We performed a chart review on 67 patients (75 thumbs) who were surgically treated for thumb carpometacarpal osteoarthritis with trapeziectomy and suture suspension arthroplasty from May 2010 to May 2016. Outcome measures included Disabilities of the Arm, Shoulder and Hand (DASH), grip strength, lateral/precision pinch strength, range of motion, and return to work/resumption of usual activities. Radiographic images were used to measure first metacarpal subsidence into the trapezial space. Results: Clinical outcomes were satisfactory, showing an initial postoperative DASH score of 45.94, which decreased to 27.93 at 6 months postoperatively and to 19.69 at 1 year postoperatively. Radiographic images revealed a mean first metacarpal subsidence of 39% compared with the preoperative images. Grip and pinch strengths showed steady improvement from initial postoperative to final follow-up visits, resulting in 90% recovery of gross grasp, 77% recovery of lateral pinch, and 79% recovery of precision pinch compared with the contralateral side. Conclusions: Our study has found that suture suspension arthroplasty with trapeziectomy is an effective treatment for thumb basal joint arthritis. Suture suspension arthroplasty allows for short immobilization time, avoids tendon sacrifice, avoids anchor use, and leaves a cosmetically appealing scar. Furthermore, a relationship of any significance between postoperative first metacarpal subsidence and functional outcomes does not appear.

Background: Radiocarpal dislocations are rare injuries that result from high-energy forces across the wrist with the hallmark finding of radiocarpal ligament disruption. Published treatment methods are comprehensive with moderate-to-good outcomes. The purpose of this study was to review the treatment of radiocarpal dislocations with a dorsal wrist spanning plate. Methods: A retrospective review was conducted analyzing the radiographic and clinical outcomes of patients treated for a radiocarpal dislocation using a dorsal wrist spanning plate over a 10-year period. Outcomes assessed included radiographic joint incongruity and arthrosis, wrist range of motion, grip strength, Visual Analogue Scale (VAS) score, surgical complications, and Disabilities of the Arm, Shoulder, and Hand (DASH) score. Results: Thirteen patients were treated with a dorsal wrist spanning plate for radiocarpal dislocation with a mean follow-up of 615 days from the time of initial surgery. Six patients (46%) had associated distal radioulnar joint instability. The mean wrist range of motion at the final follow-up was: flexion 39°, extension 44°, pronation 79°, and supination 84°. One patient (8%) developed ulnar translation of the carpus, and 11 patients (85%) developed radiographic posttraumatic wrist arthrosis. Mean VAS and DASH scores were 4 and 18, respectively. Conclusions: Acute treatment with a dorsal wrist spanning plate in this series resulted in comparable outcomes to what have been previously reported in the literature. The dorsal wrist spanning plate offers the surgeon a reliable method of stabilization, with minimal additional surgical trauma to the wrist, while avoiding the potential for infections that develop with other treatment methods.

Background: The development of trigger digit after carpal tunnel syndrome release surgery has been widely reported. Lluch described reconstruction of the flexor retinaculum in elongated position to prevent such complication. Methods: We conducted a retrospective review to determine whether patients who undergo reconstruction in elongated position of the flexor retinaculum have a lower incidence of trigger digit postoperatively. In total, 1050 patients were included, 865 of whom had undergone traditional carpal tunnel release and 185 flexor retinaculum reconstruction. Results: No differences were found in the incidence of trigger digit after surgery (8.7% of the patients who underwent traditional release vs 11.9% in the reconstruction group). Neither difference was found when comparing mean time with the development of trigger digit. Conclusions: In the absence of randomized long-term studies comparing traditional release and reconstruction in elongated position after carpal tunnel release, given our results, we see no reason to favor reconstruction over standard carpal tunnel release as a means to prevent postoperative triggering of digits.

Background: Metacarpal factures are common, comprising up to 50% of hand fractures. More work is needed to further our understanding of metacarpal anatomy to improve fixation techniques and reduce postoperative complications following surgical implants. The purpose of this anatomic study was to evaluate the length, midshaft metaphyseal width, and area of the articular surface of the head (AH) and base (AB) of metacarpals 1 to 5. Methods: This prospective study assessed measures from 17 cadavers at 1 institution's anatomy lab. The anatomic dimensions of the metacarpals in both the right and left hands were measured. Epidemiological data including sex and age at death were also collected. Results: In all, 29 hands were dissected for metacarpal anatomic measurements, for a total of 145 metacarpals. The second metacarpal was longest, at 69.58 mm. Multivariate analysis of variance revealed a significant effect of sex overall, with greater metacarpal dimensions in men. Increasing age was associated with decreasing dimensions, except for AH of metacarpal 1 (F = 3.43, P = .02) and AB of metacarpal 1 (F = 11.54, P < .001) and 4 (F = 4.21, P = .01). Multiple metacarpal dimensions were also significantly correlated with each other. Conclusion: Our data reveal further information regarding metacarpal dimensions of length, midshaft width, and AH and AB. The results allow for potential to improve surgical management through improving metacarpal implants, developing an optimal plate and screw design, techniques to better accommodate anatomical differences based on age and sex, reducing postoperative complications and improving the standard of care.
