Aims and Objectives: Background: Postoperative persistent pain occurs in approximately 10% of surgically treated patients. It incapacitates and reduces quality of life in those affected. The aetiology is poorly understood, predictive factors are currently unknown, diagnosis and therapy are difficult. Objectives: To evaluate the benefit of dermal thermography in the diagnosis and therapy of persistent postoperative pain. Study design: retrospective, Level of evidence IV Materials and Methods: A single surgeon performed highly standardized ACL reconstructions, arthroscopies and total endoprotheses of the knee. Patients were seen six weeks postoperative for clinical and thermographic evaluation. Regions of interest were defined for the affected knee, a control region defined for the contralateral knee. The thermographic image was used to pinpoint a site for subcutaneous local anaesthesia. The clinical evaluation was then repeated. Results: Patients in total (n=133), arthroscopy (n=21), total endoprothesis (n=42), ACL (n=50). If the temperature difference (TD) between the site of pathology and the average ipsilateral knee temperature was negative, pathology was classified as hypothermic (n=19), otherwise hyperthermic (n=94). Arthroscopically treated patients showed a TD of 0,88 ± 0,39 °C in hyperthermic (n=12) and -0,811 ± 0,623 °C in hypothermic (n=9) knees. Prosthetically treated patients showed a TD of 1,29 ± 0,51 °C in hyperthermic (n=37) and -0,88 ± 0,33 °C in hypothermic (n=5) knees. ACL treated patients showed a TD of 1,20 ± 0,48 °C in hyperthermic (n=45) and -0,62 ± 0,41 °C in hypothermic (n=5) knees. The difference in temperature between the site of pathology and the average temperature of the ipsilateral knee was significant for all subgroups: arthroscopy-hypothermic p < 0,001, arthroscopy-hypothermic p < 0,005; endoprothesis-hyperthermic p < 0,001, endoprothesis-hypothermic p < 0,004; ACL-hyperthermic p < 0,001, ACL-hypothermic p < 0,027. In contrast to the hyperthermic groups (for all p < 0,001), there was no significant difference between the site of pathology and the contralateral control region in the hypothermic groups. All patients reported a reduction of pain and better mobility after subcutaneous infiltration with Scandicain 2% at the thermographically defined site of pathology. Conclusion: Thermography is useful to pinpoint sites of pathology in persistent postoperative pain. Two types of thermal abnormality could be identified at the site of pathology: hypo- and hyperthermic. Local anaesthesia at the site of pathology resulted in pain reduction and improved mobility. Further studies are necessary to understand the postoperative thermal changes in order to devise a suitable therapy.

Abstract Background Direct-to-implant (DTI) breast reconstruction provides high-quality aesthetic results in appropriate candidates. Most commonly, implants are placed in the subpectoral space which can lead to pain and breast animation. Surgical and technological advances have allowed for successful prepectoral implant placement which may eliminate these trade-offs. Objectives Here we present early outcomes from 153 reconstructions in 94 patients who underwent prepectoral DTI. We sought to determine whether these patients have less postoperative pain and narcotic use than subpectoral implant or expander placement. Methods A retrospective review was performed for all prepectoral DTI reconstructions at our institution from 2015 to 2016. Data were collected on postoperative pain and narcotic use while in hospital. Results The average follow-up time was 8.5 months (range, 3–17 months) and the overall complication rate was 27% (n = 41) with the most common complications being skin necrosis (9%, n = 13) and infection (7%, n = 11). No statistically significant difference in complications was found in patients who underwent postmastectomy radiation therapy. Patients who underwent prepectoral DTI reconstruction did not have a statistically significant difference in postoperative pain and narcotic use while in-hospital compared with other techniques. Conclusion Prepectoral DTI reconstruction provides good results with similar complication rates to subpectoral techniques. Prepectoral DTI eliminates the problem of breast animation. Although our series did not reach statistical significance in pain scores or requirement for postoperative narcotics, we believe that it is an important preliminary result and with larger numbers we anticipate a more definitive conclusion.

Background Glenohumeral internal rotation deficit, often diagnosed in players of overhead sports, has been associated with the development of secondary shoulder lesions. Hypothesis Asymptomatic players of different overhead sports will exhibit variable degrees of glenohumeral internal rotation deficit. Study Design Cross-sectional study; Level of evidence, 3. Methods Fifty-four asymptomatic male volunteers (108 shoulders) divided into 3 groups (tennis players, swimmers, control group) underwent measurements of glenohumeral internal and external rotation using clinical examination with scapular stabilization. Measurements of dominant and nondominant shoulders were compared within and between groups. Glenohumeral internal rotation deficit (GIRD) was defined as the difference in internal rotation between the nondominant and dominant shoulders. Results In tennis players, mean GIRD was 23.9° ± 8.4° (P < .001); in swimmers, 12° ± 6.8° (P < .001); and in the control group, 4.9° ± 7.4° (P = .035). Dominant shoulders showed significant difference between all groups, and the difference in internal rotation of the dominant shoulder between the group of tennis players in comparison with the control group (27.6°, P < .001) was greater than the difference in internal rotation of the dominant shoulder found in the group of swimmers compared with the control group (17.9°, P < .001). Between tennis players and swimmers, the difference in internal rotation of the dominant shoulder was 9.7° (P = .002). Conclusion Dominant limbs showed less glenohumeral internal rotation than the nondominant limbs in all groups, with the deficit in the group of tennis players about twice the deficit found for swimmers. Mean difference between limbs in the control group was less than 5°, which is within normal parameters according to most studies. There were statistically significant differences between all groups when dominant shoulders were compared with each other, differences that were not compensated by external rotation gain. Tennis players had the least range of motion, followed by swimmers.

Background: Arthroscopic labral repair combined with capsular plication decreases joint volume and restores glenoid labral bumper height; thus, the procedure helps decrease capsular redundancy. However, the decreased volume and restored glenoid labral bumper height could change over time, which could influence the outcome of the operation. Purpose: To (1) measure glenoid labral bumper height and capsular volume quantitatively in serial computed tomography arthrography (CTA) and evaluate the relationship between bumper height and joint volume and (2) compare the difference in bumper height and joint volume between groups with and without apprehension after arthroscopic Bankart repair. Study Design: Case-control study; Level of evidence, 3. Methods: Patients who had undergone arthroscopic Bankart repair between January 2012 and June 2016, and were assessed by CTA 3 to 6 months and 12 to 18 months after the operation were included. An image reconstruction program (3-dimensional slicer) was used to calculate inferior, anterior-inferior, and posterior-inferior joint volumes; the ratio of the anterior-inferior volume to the inferior volume was defined as the anterior-inferior volume fraction (VFAI). We also measured glenoid labral bumper height at the 5-, 4-, and 3-o’clock positions. Results: A total of 50 patients were enrolled as study participants (mean age, 25.2 ± 9.29 years). Of these, 10 patients had either redislocation or apprehension, and 40 patients had neither. A significant correlation was observed between 5-o’clock glenoid labral bumper height and VFAI on early CTA (3-6 months) and late CTA (12-18 months) (early CTA: Pearson coefficient, –0.335, P = .040; late CTA: Pearson coefficient, –0.468, P = .003). VFAI at the early CTA was 42.20 ± 10.15 in the group with apprehension and 33.49 ± 9.66 in the group without apprehension; a significant difference was observed. VFAI at the late CTA was 45.84 ± 11.97 in the group with apprehension and 37.65 ± 9.70 in the group without apprehension and thus showed a significant difference between the 2 groups. However, the 3-, 4-, and 5-o’clock glenoid labral bumper heights on early and late CTAs did not show a statistically significant difference between the 2 groups. Conclusion: Early postoperative VFAI is related to postoperative apprehension and redislocation and might be reduced by increasing the 5-o’clock glenoid labral bumper height.

Background: Surgery for degenerative foot and ankle conditions often results in a lengthy recovery. Current outcome measures do not accurately assess postoperative mobility, especially in older patients. The Life-Space Assessment (LSA), a questionnaire quantifying patients’ mobility after a medical event, was used in this study to assess perioperative mobility in total hip arthroplasty (THA) and foot and ankle surgery patients. We hypothesized that patients undergoing elective foot and ankle surgery would have greater postoperative mobility limitation than THA patients. Methods: Preoperative, 3-month, and 6-month postoperative LSA data were collected from THA and foot and ankle cohorts. Twelve-month postoperative data were obtained for the foot and ankle group as well. Patient demographics were recorded, and data were analyzed using a Mann-Whitney U test. Results: Twenty-eight degenerative foot and ankle operative patients and 38 THA patients met inclusion criteria. Only patients aged ≥60 years were included in this study. The mean preoperative LSA score was lower in the foot and ankle group (68.8) compared with THA (74.0), although the difference was not statistically significant ( P = .602). THA patients showed a significant increase in LSA score from preoperative (74) to 6 months postoperation (95.9) ( P = .003); however, foot and ankle patients showed no significant difference between preoperative (68.8) and 6-month (61.2) scores ( P = .468). Twelve months postoperatively, foot and ankle patients showed improvement in LSA score (88.3) compared with preoperation ( P = .065). Conclusion: Compared with THA, recovery of mobility after foot and ankle surgery was slower. THA patients exhibited improved mobility as early as 3 months after surgery, whereas foot and ankle patients did not show full improvement until 12 months. This work will assist the foot and ankle specialist in educating patients about challenges in mobility during their recovery from surgery. Level of Evidence: Level II, prospective cohort study.

Purpose Currently no guidelines exist for the timing of the injection of anesthetics in surgeries performed under general anesthesia to minimize postoperative pain. To better understand the role of timing of the injection of local anesthesia in hand surgery performed under general anesthesia, we evaluated the effect of pre- versus postincisional local analgesic injection on immediate postoperative pain experience. We hypothesize that the preincisional (preemptive) injection will result in decreased immediate postoperative pain experience and analgesic use when compared with postincisional injection. Methods Consecutive cases of thumb basal joint arthroplasty performed over a 4-year period were retrospectively reviewed. During the first half of the study period, the surgical site was infiltrated with 0.5% bupivacaine at the completion of surgery following closure. During the second half of the study period, the surgical site was infiltrated with 0.5% bupivacaine prior to skin incision. Data collected included patient demographics, immediate postoperative recovery room (PACU) pain scores, and postoperative opioid consumption in morphine equivalents. Results Two-tailed t-test identified no significant difference between the pre- and postincision cohorts relative to PACU entrance pain scores and time spent in the PACU. PACU exit pain scores were significantly lower in the preincision cohort. The mean PACU pain score was also significantly lower in the preincision cohort. PACU opioid consumption, converted into morphine equivalents, was found to be 211 mg in the preincision versus 299 mg in the postincision cohort. Conclusion The preincisional (preemptive) injection of local anesthesia was found to result in lower pain scores during and upon exit of the PACU as compared with the postclosure group. In addition, the preincision cohort also trended toward lower opioid consumption while in the PACU. Consideration should be given to the routine use of preincision injection of local anesthesia to maximize pain relief in a multimodal pain strategy in hand surgical patients. Level of Evidence Therapeutic level III.

The Quick disabilities of the arm, shoulder and hand (QuickDASH) patient-reported outcome measure is frequently used to assess disabilities and symptoms of the upper extremity. This study compares real preoperative QuickDASH scores and remembered preoperative QuickDASH scores. Remembered preoperative QuickDASH scores were obtained 45 months (39–67) after surgery. Patient material consisted of 160 patients operated for Dupuytren’s contracture, carpal tunnel syndrome, thumb basal joint arthrosis, and shoulder pain. All patients had completed QuickDASH questionnaires before surgery. Paired T-tests, linear mixed models, and limits of agreement were used for analyses. There was a significant difference between remembered and real preoperative scores (mean 7.6, SD 15.6; SEM 1.2). Neither diagnosis, age, gender, nor time between surgery and review influenced the difference significantly. A linear mixed model was constructed to investigate the ability to retrospectively predict preoperative QuickDASH scores. Remembered preoperative QuickDASH cannot be used in individual patients because of the high inaccuracy. Level of evidence: III

ABSTRACT Objectives To determine the incidence and intensity of pain and the areas most affected by injuries with musculoskeletal pain, and the incidence and severity of “injuries defined by time of leave” in games and training of soccer referees in a triennium. Methods An interview was conducted with 257 referees using a web application. With this tool, a monthly evaluation form was sent to the referees with questions that measured the incidence, location, and pain intensity of injuries with complaints of pain and time of leave, severity in games and training in the years 2012, 2013, and 2014. The numerical pain scale was used to classify the pain intensity of the lesions with pain complaint. Results There was no difference between the years studied in relation to injuries with pain complaints, both in games and in training. Mean values were 37.8/1,000 hours in games and 39.9/1,000 hours in training, with a mean incidence of “ injuries defined by time of leave” of 3.7/1,000 hours in games. The difference was significantly higher in 2013 compared to 2012 and 2014, and in training, the average incidence was 3.5/1,000 hours, with a significantly higher difference in 2012 compared to 2013 and 2014. Conclusion Lesions with pain complaints did not present a significant difference in games compared to training; in the lesions by time of leave, the incidence in games was higher than in training, and the most frequent type of injury was low-degree muscle pain, predominantly in the thigh and triceps surae.

Objective: If preferable, the regional anesthesia is a more preferred method than general anesthesia. The preference for regional anesthesia increases as postoperative recovery is quicker, hospitalization is less and hospital costs are low. Material and methods: We retrospectively evaluated the hemodynamic findings, postoperative pain, hospital, and intensive care stay in patients aged 18-80 who underwent lower extremity surgery with regional anesthesia in the last 1 year. We divided the cases into 3 groups; Group 1 (n =114) patients with a peripheral nerve block, Group 2 (n =104) spinal anesthesia, and Group 3 (n =81) epidural anesthesia. Results: The difference between group 1 and 2, age hospitalization, and time of stay in intensive care was statistically significant. (P=0.021) (P=0.000). The difference between group 1 and 3 Intensive care unit stay was statistically significant (P = 0.003). The difference between the length of stay in the intensive care unit between groups 2 and 3 was found as statistically significant (P = 0.000). There was no significant difference in terms of hospital stay. Group 1 was found to have the shortest duration of intensive care stay. Conclusion: In lower extremity surgeries, peripheral nerve blocks may have provided more hemodynamic stability and longer analgesic effect compared to central blocks.

Background: The relationship between depressive symptoms and patient outcomes after hallux valgus surgery has not been well-studied. We hypothesized that patients with depressive symptoms would have greater subjective dysfunction preoperatively and less functional improvement and satisfaction after surgery when compared with patients without depressive symptoms. Methods: A total of 239 adult patients who had surgical hallux valgus correction over a 2-year period were retrospectively enrolled. A telephone survey was administered prospectively at least 11 months postoperatively inquiring about overall satisfaction level with surgery and satisfaction with postoperative pain level. A scale of 0 to 6 was used, with 0 indicating complete dissatisfaction and 6 indicating complete satisfaction. Patients were divided into 2 groups based on depressive symptoms; a Short Form–12 mental component score (SF-12 MCS) of less than 45.6 points was considered indicative of active depressive symptoms based on literature correlating SF-12 scores with Patient Health Questionnaire–9 for depression. Given the great variability of depressive symptoms in patients with or without self-reported depression and medicated or unmedicated status, we elected to use the MCS classification of depressive symptoms for our analysis. Data from 239 patients were available for analysis, with an average age of 51.6 years and 207 women (87%). Two hundred eighteen patients (91%) completed preoperative functional scores, 160 patients (67%) completed the satisfaction survey at an average of 23 months postoperatively (range 11 to 43 months), and 154 patients (64%) completed postoperative functional scores an average of 21 months postoperatively (range, 11-44 months). Results Thirty-six of 239 patients (15%) with baseline functional scores exhibited depressive symptoms. There was no significant difference in baseline functional scores and pain levels between groups with the exception of the SF-12 MCS ( P < .001). Most outcomes improved significantly over time, including the SF-12 physical component score ( P = .013), Foot and Ankle Ability Measure (FAAM; P = .013), and FAAM Activities of Daily Living ( P = .046). The patients with depressive symptoms generally had lower scores at baseline and final follow-up in all functional scores, with the exception of visual analog scale (VAS). VAS pain scores started higher in the group of patients with depressive symptoms and ended lower. Satisfaction with postoperative pain was lower in the group with depressive symptoms when compared with patients without depressive symptoms (3.6 vs 4.5, P = .042). There was no significant difference in satisfaction after surgery between groups ( P = .251). Conclusion: Patients with depressive symptoms had greater pain at baseline and less pain postoperatively when compared with patients without depressive symptoms; however, satisfaction levels with postoperative pain were lower in these patients. Furthermore, most functional scores were lower in patients with depressive symptoms, with the exception of the MCS. Reported history of depression was not associated with any significant difference in functional outcome scores or satisfaction. Further study is warranted to determine why patients with depressive symptoms fare worse after surgical hallux valgus correction by most subjective measures. Level of Evidence: Level III, comparative study.

Abstract Purpose To evaluate the relationship between kinesiophobia and patient's return to sport after shoulder stabilization surgery. The hypothesis was that kinesiophobia represents an independent factor correlated to the difference between preinjury and postoperative level of sport. Methods This study retrospectively evaluated 66 patients (mean age: 35.5, standard deviation [SD] = 9.9 years) and at a mean follow-up of 61.1 (SD = 37.5) months after arthroscopic Bankart's repair or open Bristow–Latarjet procedure. Kinesiophobia was assessed with the Tampa Scale for Kinesiophobia (TSK); return to the preinjury sport was assessed by the difference between baseline and postoperative degree of shoulder involvement in sport (D-DOSIS) scale. The Western Ontario Shoulder Instability index (WOSI) was used to evaluate participants' perceptions of shoulder function. Results TSK showed correlation with D-DOSIS (ρ = 0.505, p < 0.001) and the WOSI score (ρ = 0.589, p < 0.001). There was significant difference in TSK and WOSI scores between participants who had and had not returned to their previous level of sport participation (p = 0.006, and 0.0001, respectively). Conclusion This study demonstrated that kinesiophobia is correlated to the return to sport after shoulder stabilization surgery. Level of Evidence Level IV, retrospective case series.
