Efficacy of supervised self-reduction vs. physician-assisted techniques for anterior shoulder dislocations: a systematic review and meta-analysis.

BACKGROUND AND OBJECTIVE: Reduction manipulation using self-reduction procedures such as Stimson, Milch, and Boss-Holtzach should be easy and effective and also require less force, pain medication, and outside assistance. This technique should not cause damage to arteries, nerves, or shoulder joint components. Self-reduction is straightforward and can be done in clinics, making it ideal for people who suffer from shoulder joint dislocation frequently. The goal of this study is to compare the effectiveness of supervised self-reduction procedures vs. physician-assisted treatments in the treatment of anterior shoulder dislocations. METHOD: We conducted a comprehensive search on PubMed, Scopus, Web of Science, and Cochrane up to March 22, 2023, using the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) checklist. Relevant articles were reviewed, with a focus on studies comparing supervised self-reduction techniques to physician-assisted techniques in cases of anterior shoulder dislocation. RESULTS: Four papers in all were included in the meta-analysis. One prospective trial, one case-control study, one randomized clinical trial, and one retrospective trial made up these studies. The studies involved 283 patients in the physician-assisted group and 180 patients in the supervised self-reduction group. They were carried out in four European countries: Italy, Germany, Portugal, and Spain. The success rate of supervised self-reduction techniques was significantly higher, with an odds ratio of 2.71 (95% CI 1.25-5.58, p-value = 0.01). Based on the Visual Analog Scale (VAS) score, the physician-assisted group reported significantly higher maximum pain, with a mean difference of 1.98 (95% CI 1.24-2.72, p-value < 0.01). The self-reduction approaches exhibit shorter reduction time in comparison to physician-assisted groups. In addition, the self-reduction groups do not document any complications. Based on the GRADE system, the level of assurance in the evidence was high. CONCLUSION: Supervised self-reduction techniques outperform in terms of success rate and reduction-related maximum pain. These techniques could be used as an effective first-line treatment for anterior shoulder dislocation, potentially reducing the need for analgesics and emergency room visits.

Rate of Successful Shoulder Reduction on First Confirmatory Imaging in the Emergency Department.

BACKGROUND: Management of acute shoulder dislocation in the emergency department (ED) is common. OBJECTIVE: This study describes the rate, risk factors, and length of stay (LOS) associated with shoulder dislocation reduction failure in the ED. METHODS: The study was a retrospective case-control study of patients 18 years and older presenting to the ED with acute shoulder dislocation who underwent attempted reduction. Patients with successful reduction on post-reduction first confirmatory imaging are compared with those requiring multiple attempts. RESULTS: Of 398 ED encounters when a shoulder reduction was attempted in the ED, 18.8% (75/398 [95% CI 15.2-22.9%]) required multiple reduction attempts. Patients with successful reduction on first confirmatory imaging were more commonly male (80.2% [95% CI 75.6-84.3%] vs. 68.0% [95% CI 56.8-77.8%]; p = 0.0220), discharged home from the ED (95.4% [95% CI 92.6-97.3%] vs. 84.0% [95% CI 74.4-91.0%]; p = 0.0004), reduced using a traction/countertraction technique (42.1% [95% CI 36.8-47.6%] vs. 29.3% [95% CI 19.9-40.4%]; p = 0.0415), and less likely to have a pre-reduction fracture (26.0% [95% CI 21.4-31.0%] vs. 45.3% [95% CI 34.4-56.7%]; p = 0.0010). Mean length of stay (LOS) for those with successful reduction on first confirmatory imaging was 2 hours and 8 minutes shorter than for those with more than one attempt (p < 0.001). CONCLUSIONS: The rate of failed first-pass reduction is higher than previously reported. Furthermore, the ED LOS was significantly longer in patients requiring multiple attempts. Knowledge of the failure rate and risk factors may raise physician awareness and guide future studies evaluating approaches for verification of reduction success.

Nursemaid's elbow: Radial head subluxation injuries in children.

ABSTRACT: Radial head subluxation, or nursemaid's elbow, is a common orthopedic complaint in children and often is the result of a pulling injury to the affected arm. Although this injury largely is a clinical diagnosis, different imaging modalities may be used to identify it and confirm successful reduction. Multiple manipulative techniques can be used to treat this injury and methods are generally specific to clinician preference. This article reviews the causes, evaluation, and management of radial head subluxation.

Effect of Using the Modified Milch Technique on Quality of Life in Patients with Anterior Dislocation of the Shoulder Joint.

Objective: To evaluate the effect of the Milch technique on quality of life (QoL) in patients with anterior dislocation of the shoulder joint. Methods: A total of 126 patients undergoing manual reduction for anterior dislocation of the shoulder in our hospital from January 2021 to January 2022 were prospectively enrolled in this study. The randomized number table method was used to divide patients into the study group (63 patients) and the control group (63 patients). The study group was treated with a modified Milch technique while the control group was treated with the Hippocratic method. Success rate and complications were compared to evaluate the effectiveness of manual reduction. Clinical assessment of shoulder function included the Constant-Murley Score and visual analog scale (VAS) before, during and after manual reduction. Results: The success rate of primary and secondary reduction in the study group was significantly higher than in the control group (87.30% vs 61.90, respectively; P = .001; 11.11% vs 25.40%, respectively; P = .038). The failure rate in the study group was significantly lower than in the control group (1.59% vs 12.70%, respectively; P = .015). The time required for reduction in the study and control groups was 58.87 ± 7.92 seconds and 93.09 ± 8.01 seconds, respectively; a significant difference (t = -24.113; P < .001). There was no statistically significant difference in VAS scores before and during reduction in the 2 groups. After reduction, VAS scores in the study group were significantly lower than in the control group (1.02 ± 0.01 vs 1.14 ± 0.26, respectively; P < .001). There were no significant differences in pain level, activities of daily living, joint range of motion or muscle strength between the 2 groups before and after reduction (P > .05). After reduction, health status, emotional function, mental health, physiological function, physiological function, physical pain, vitality and social function scores in the study group were significantly higher than in the control group (P < .05). There were 4 avulsion fractures and 2 humeral fractures in the control group; no complications occurred in the study group, with a significant difference (χ2 = 6.289; P = .012). Conclusion: The Milch technique can improve the QoL in patients with anterior dislocation of the shoulder, and the success rate of the reduction is high.

Han's technique: a new reduction technique for acute anterior shoulder dislocation.

INTRODUCTION: Acute anterior shoulder dislocation (AASD) is the most common joint dislocation. Here, we introduced a new reduction technique for AASD, named "Han's technique" (or "Touch overhead technique"). METHODS: Patients diagnosed with AASD were treated with "Han's technique" in the orthopaedic department of our hospital from October 2018 to November 2020. An orthopedic surgeon performed the reduction maneuver without any anesthesia or sedation throughout the reduction process. The fundamental information and related data were recorded, including patients' age, sex, dislocation side, previous dislocations history, reduction time, number of attempts at reduction, success rate of the reduction, intensity of pain during reduction using the 10-point visual analogue scale score (VAS), any complications, with or without the fracture and neurovascular examination results. RESULTS: Forty-one patients with AASD were involved in our study. Thirty-nine cases (95%) were primary dislocation. Eleven patients (27%) were complicated with large tubercle fracture and one patient (2%) complicated with inferior glenoid fractures. All patients were successfully reduced by Han's technique with mean reduction time was 138 s. The pain score during the reduction operation is only1.83 ± 0.83 points. No neurovascular injury or iatrogenic fracture was found after reduction in all patients. CONCLUSIONS: Han's technique (or Touch overhead technique) is a simple, safe, effective, mild and easy to master which can be operated by one surgeon without anesthesia or sedation for AASD.

Modified chair method: an easy and efficient reduction method without medication for anterior shoulder dislocation.

BACKGROUND: Various maneuvers have been introduced to address anterior shoulder dislocations. Chair method allows the patient to sit comfortably and feel less pain during the reduction procedure. However, the rarity of comparative studies led to a lack of evidence to popularize. The present study aimed to introduce a modified chair (MOC) reduction method for anterior shoulder dislocation and explore its effectiveness compared with the traditional Hippocratic approach. METHODS: This is a single-center retrospective study of 257 patients with anterior shoulder dislocation from September 2020 and July 2021. Patients were divided into two groups according to the reduction method they received (either the Hippocratic method or the MOC method). Success rate, reduction time, visual analog scale (VAS) pain score, satisfaction level, and a new indicator, pain index (reduction time (s)* VAS/ 10), were compared. RESULTS: One hundred sixteen patients (43 females, 73 males) underwent the Hippocratic method, and 141 (65 females, 76 males) MOC method. A significantly higher success rate was seen in the MOC group (96.5%(136/141) vs. 84.5%(98/116) in the Hippocratic group; OR 5, 95%CI 1.79 ~ 13.91; p = 0.002). Pain index of the patients in the MOC group was much lower than that in the Hippocratic group (3.20 (2.10, 4.53) vs. 36.70 (22.40, 47.25), p <  0.001). The reduction time, VAS pain score, and satisfaction level also favored the MOC method. CONCLUSIONS: The MOC method is an easy and efficient reduction method with minimum assistance for anterior shoulder dislocations. Physicians can skillfully perform this procedure with the help of their body weight. The MOC method could be attempted for shoulder dislocations in the emergency department.

Self-reduction techniques taught via smartphone are effective for anterior shoulder dislocation: prospective randomized study.

PURPOSE: To prospectively compare the effectiveness of three methods for self-assisted shoulder reduction demonstrated using a smartphone video link. BACKGROUND: Anterior shoulder dislocation is very common among young adults. Patients often seek medical assistance in the emergency department to reduce their shoulder. Many techniques for shoulder reduction had been described, some of which do not require professional assistance and can be performed by patients themselves. METHODS: Patients admitted with anterior shoulder dislocation were randomized to either the Stimson, Milch or the Boss-Holtzach-Matter technique. Each patient was given a link to watch a short instructional video on his smartphone and instructed to attempt self-reduction. Success of the reduction, pain level, patient satisfaction and complications were recorded. RESULTS: The study cohort consisted of 58 patients (mean age was 31.6 (18-66, median = 27), 82% males, 88% right hand dominant). Success rate using Boss-Holtzach-Matter (10 of 19, 53%) and self-assisted Milch (11 of 20, 55%) were significantly higher than with the self-assisted Stimson method (3 of 19, 16%), p < 0.05. Pain levels improved from 8.4 (2-10) to 3.1 (0-10) following the reduction. Patient subjective satisfaction from the reduction attempt was 6.7 (0-10). No complications were observed. CONCLUSION:  Both the Self-assisted Milch and the Boss-Holtzach-Matter techniques are ideal for reduction of anterior shoulder dislocation without medical assistance. Both methods can be successfully performed without assistance or previous education and taught using an instructional video. LEVEL OF EVIDENCE: Level II.

Immediate Effect of Ankle Mobilization on Range of Motion, Dynamic Knee Valgus, and Knee Pain in Women With Patellofemoral Pain and Ankle Dorsiflexion Restriction: A Randomized Controlled Trial With 48-Hour Follow-Up.

CONTEXT: Restriction in ankle dorsiflexion range of motion (ROM) has been previously associated with excessive dynamic knee valgus. This, in turn, has been correlated with knee pain in women with patellofemoral pain. OBJECTIVES: To investigate the immediate effect of 3 ankle mobilization techniques on dorsiflexion ROM, dynamic knee valgus, knee pain, and patient perceptions of improvement in women with patellofemoral pain and ankle dorsiflexion restriction. DESIGN: Randomized controlled trial with 3 arms. SETTING: Biomechanics laboratory. PARTICIPANTS: A total of 117 women with patellofemoral pain who display ankle dorsiflexion restriction were divided into 3 groups: ankle mobilization with anterior tibia glide (n = 39), ankle mobilization with posterior tibia glide (n = 39), and ankle mobilization with anterior and posterior tibia glide (n = 39). INTERVENTION(S): The participants received a single session of ankle mobilization with movement technique. MAIN OUTCOME MEASURES: Dorsiflexion ROM (weight-bearing lunge test), dynamic knee valgus (frontal plane projection angle), knee pain (numeric pain rating scale), and patient perceptions of improvement (global perceived effect scale). The outcome measures were collected at the baseline, immediate postintervention (immediate reassessment), and 48 hours postintervention (48 h reassessment). RESULTS: There were no significant differences between the 3 treatment groups regarding dorsiflexion ROM and patient perceptions of improvement. Compared with mobilization with anterior and posterior tibia glide, mobilization with anterior tibia glide promoted greater increase in dynamic knee valgus (P = .02) and greater knee pain reduction (P = .02) at immediate reassessment. Also compared with mobilization with anterior and posterior tibia glide, mobilization with posterior tibia glide promoted greater knee pain reduction (P < .01) at immediate reassessment. CONCLUSION: In our sample, the direction of the tibia glide in ankle mobilization accounted for significant changes only in dynamic knee valgus and knee pain in the immediate reassessment.

Comparison between new modified external rotation method and external rotation method for reduction of ASD.

INTRODUCTION: Dislocation of the shoulder joint is common and is mainly anterior. Several reduction methods have been described and the external reduction method (ERM) is one of the newest. We modified the ERM by making some additions in hopes to develop a less painful, quick and simple method. The aim of this study was to compare the new modified external rotation reduction method (MERM) with ERM in acute anterior shoulder dislocations (ASD). METHODS: A total of 62 patients with ASD were classified randomly into 2 groups. The reduction was performed with MERM in one group and with ERM in the other group and the results were compared. Patients' pain scores, reduction time, success rate of the reduction methods, age, sex, dislocation side, dislocation time, previous dislocations history, injury mechanism, any complications, reduction time and neurovascular examination were collected. Parametric and nonparametric analyses were used to compare MERM and ERM. RESULTS: The study cohort consisted of 62 patients (52 males, 10 females; mean age, 35 years; age range, 18-73 years) who were randomly assigned to treatment with the MERM (n = 32) or the ERM (n = 30). There was a statistically significant difference between the two methods in terms of time, and the MERM can be applied much faster than ERM (1.34 ±â€¯1.41 min vs 3.05 ±â€¯1.93 min; p < 0.001). The intra-reduction VAS pain score was not significantly in patients who were treated with MERM (85.31 ±â€¯10.39 vs. 78.33 ±â€¯16.54; p = 0.122). CONCLUSION: MERM can be an alternate method compared to the ERM for the reduction of ASD.

Anatomic healing after non-operative treatment of a large, displaced anterior glenoid rim fracture after primary traumatic anterior shoulder dislocation - a case report.

BACKGROUND: Large, displaced anterior glenoid rim fractures after primary traumatic anterior shoulder dislocation are usually managed by surgical stabilization. Although there is little evidence supporting surgical management, it is often preferred over non-operative treatment. This case report describes non-operative management of such large, displaced anterior glenoid rim fracture with CT- and MRI-based documentation of anatomical healing of the fracture fragment, a finding that has not been described previously. CASE PRESENTATION: This case report describes a 49-year-old male, right-hand dominant, carpenter, who had a left-sided primary anterior shoulder dislocation after a fall while skiing. Initial plain radiographs showed a reduced glenohumeral joint with a large, displaced anterior glenoid rim fracture. CT-evaluation showed a centered humeral head, and as per our institutional protocol, non-operative management was initiated. Longitudinal radiographic assessment at 2 weeks, 4.5 months and 12 months showed reduction of the initially severely displaced fracture fragment. MRI- and CT-evaluation after 12 months confirmed anatomical healing of the fragment. At final follow-up, the patient was highly satisfied, although the healing process was complicated by posttraumatic frozen shoulder, which has had almost fully resolved after 12 months. CONCLUSIONS: Given that the glenohumeral joint is concentrically reduced, large (displaced) anterior glenoid rim fractures after traumatic primary shoulder dislocation can be successfully treated non-operatively, with the potential of anatomical fracture fragment healing. Therefore, it remains subject to conservative treatment at our institution and surgical stabilization is reserved for patients with a decentered humeral head or persistent glenohumeral instability.

What Is the Cost of a "Cast Holiday" in Treating Children With Early Onset Scoliosis (EOS) With Elongation Derotation Flexion (EDF, "Mehta") Casting?

INTRODUCTION: Serial casting of children with early onset scoliosis (EOS) is an established treatment option. A break from cast treatment often called a "cast holiday," (CH) is often allowed by some centers, particularly over the summer months. The impact of CHs on treatment duration or outcome has not been examined. METHODS: Institution review board approved retrospective review of children treated for EOS with elongation derotation flexion ("Mehta") casting at a children's hospital between 2001 and 2016 with a minimum of 2 years' follow-up. A CH was defined as a minimum of 4 weeks out of the cast, braced, or unbraced.The analysis was performed to determine the impact of a CH within the first 18 months of treatment. Separate analyses were performed for the entire cohort of children castedduring the study period, and then separately looking at idiopathic EOS in isolation. The impact of a CH was assessed in terms of the likelihood of achieving scoliosis <15 degrees at the final follow-up ("success"). Odds ratios were used to assess group differences between "success" ratios, and Student t tests assessed group differences for parametric data. RESULTS: Ninety children met inclusion and exclusion criteria, 31 of whom took a CH during the first 18 months of treatment (34%). This included 59 patients with idiopathic EOS (66%), 18 with syndromic EOS, 5 congenital, and 1 neuromuscular. There were no statistically significant differences between CH and no CH groups.Forty-four percent of the no CH group achieved scoliosis <15 degrees at final follow-up, as opposed to 13% of the CH group, an odds ratio of 5.3 for success without a CH. When limited to children with idiopathic EOS, 56% achieved success in the no CH, versus only 22% in the group that took a CH, an odds ratio of 4.4 for success with no CH. CONCLUSION: This study demonstrates that children treated for EOS with serial casting who take a CH within the first 18 months of treatment are less likely to achieve scoliosis <15 degrees than those who persist with treatment. LEVEL OF EVIDENCE: Level III.

Complex Clubfoot Treatment With Ponseti Method: A Latin American Multicentric Study.

BACKGROUND: Complex clubfoot is a term used to describe those feet that present after treatment with a short first metatarsal, severe plantar flexion of all metatarsals, rigid equinus, and deep folds through the sole of the foot and above the heel. Ponseti has described a modification of his original technique for the treatment of the deformity. Few series have reported the treatment outcomes of this group of patients. The purpose of this study is to analyze mid-term results and complications of a large multicenter cohort. METHODS: Patients with complex clubfoot treated at 6 tertiary-care institutions with a minimum of 1-year follow-up were retrospectively analyzed. Demographic data, previous treatment, number of casts, Achilles tenotomy, recurrences, complications, and additional procedures were documented. The patients were clinically evaluated at the time of presentation, after treatment, and at the last follow-up according to the Pirani score. All variables had a nonparametric distribution and are thus described as median (interquartile range (IQR), minimum-maximum). A comparison between the variables was performed using a Mann-Whitney U test, the change within each group was performed with a Wilcoxon-designated range test. A P-value <0.05 was used to indicate statistical significance. RESULTS: One hundred twenty-four feet (79 patients) were evaluated. The median age at initial treatment was 7 months (IQR, 15; min-max, 1 to 53 mo). The mean follow-up was 49 months (IQR, 42; min-max, 12 to 132 mo). A median of 5 casts (IQR, 5; min-max, 3 to 13) was required for correction. Percutaneous tenotomy of the Achilles tendon was performed in 96% of the feet. One hundred twenty-two feet (98%) were initially corrected; 2 feet could not be corrected and required a posteromedial release. The Pirani score improved significantly from a pretreatment mean of 6 points (IQR, 1; min-max, 4.5 to 6) to 0.5 (IQR, 0.5; min-max, 0 to 2.5) at the last follow-up (P <0.001). Seven feet (6%) presented minor complications related to casting. Relapses occurred in 29.8% (37/124). In this subgroup, the number of casts required at initial treatment was higher (6; IQR, 5; min-max, 1 to 12 vs. 4 IQR, 4; min-max, 1 to 13; P<0.001), and follow-up was significantly longer (62 mo; IQR, 58; min-max, 28 to 132 vs. 37 mo; IQR, 48, min-max, 7 to 115; P<0.001). CONCLUSIONS: Ponseti method is safe and effective for the correction of complex clubfeet. Early diagnosis and strict adherence to the Ponseti principles are key to achieve deformity correction. Patients with complex clubfoot require frequent follow-up because of a higher recurrence rate. LEVEL OF EVIDENCE: Level III-therapeutic study.

Significance of Asymmetry of Groin and Thigh Skin Creases in Developmental Dysplasia of the Hip Revisited: Results of a Comparative Study.

BACKGROUND: No high level of scientific evidence exists about the use of asymmetry of skin creases (ASC) on the groin and thigh regions in diagnosing developmental dysplasia of the hip. The aim of this comparative study was to revisit whether or not ASC was a significant clinical finding in developmental dysplasia of the hip. METHODS: This was retrospective analysis of a prospectively collected data. Control group was composed of 1000 consecutive healthy infants (mean age, 46.7 d) whose both hips were considered Graf type I (normal). Study group (SG) was composed of 246 consecutive patients (mean age, 96.5 d) whose treatments by abduction bracing were initiated due to unilateral or bilateral Graf type IIa(-) and worse hips. RESULTS: SG included 178 patients with bilateral or unilateral dysplastic hips [Graf type IIa(-), IIb, IIc] and 68 patients with at least 1 decentered hip (Graf type D, III, IV). ASC was seen in 63 of 101 patients (63%) having positive clinical finding(s). The rates of both ASC alone (P<0.001; odds ratio, 3.46) and ASC total (ASC with and without additional findings) (P<0.0001; odds ratio, 7.48) were significantly higher in SG than in control group. ASC was the only clinical finding in 31 patients and 24 of these 31 patients (77%) had unilateral or bilateral dysplastic hips. Sensitivity and specificity of ASC alone were 12.60% and 96.00%, respectively. ASC was accompanied by other clinical findings (mostly Galeazzi sign and limitation of abduction) in 32 patients and 23 of these 32 patients (72%) had at least 1 decentered hip. Sensitivity and specificity of ASC total were 25.61% and 95.60%, respectively. CONCLUSIONS: ASC is a significant finding, as there is considerable increased risk of having dysplastic or decentered hips in infants having such a finding alone or associated with other findings. ASC alone is more commonly seen in patients with dysplastic hip(s) whereas ASC is mostly accompanied with other clinical finding(s) in patients with decentered hip(s). This study shows that, ASC can be introduced as a risk factor in selected newborn hip screening programs. LEVEL OF EVIDENCE: Level II-diagnostic study.

Manipulation under anesthesia as a therapy option for postoperative knee stiffness: a retrospective matched-pair analysis.

INTRODUCTION: Due to demographic changes, total knee arthroplasty (TKA) is one of the most frequently performed orthopedic surgeries. Therapies for associated postoperative complications, such as postoperative knee stiffness (PKS), are becoming increasingly important. The aim of this retrospective matched-pair analysis was to evaluate mid-term-results following manipulation under anesthesia (MUA). MATERIALS AND METHODS: Fifty-one patients with PKS were evaluated and 51 matched-pair patients without PKS after primary TKA were chosen for the control group. In addition to the range of motion, the functionality was recorded by Knee Society Score (KSS), Western Ontario and Mc Masters Universities Osteoarthritis Index (WOMAC), and Short-Form-12 Questionnaire (SF-12). Experience of pain was mapped using a 10-point Numeric Rating Scale (NRS), and the analgesic requirement was mapped using the WHO step scheme. A final follow-up examination was conducted approximately three years after TKA. To evaluate potential risk factors for the development of PKS, TKA alignment was measured via postoperative X-ray images. RESULTS: Improvement of the average knee flexion of 35.7° and total flexion of 107.4° was detected in PKS patients after MUA. The flexion of the control group was 112.4°; no significant between-group difference was present regarding prosthesis type, sex, age and BMI. Regarding KSS, WOMAC, and SF-12, the MUA cohort achieved statistically-relevant lower overall scores than the control group, p = 0.006, p = 0.005, p = 0.001, respectively. Significantly higher experiences of pain and a higher need for analgesics in MUA patients were reported (p = 0.001 and p < 0.001, respectively). Radiological evaluation of the prosthesis alignment did not show any differences between the two groups. CONCLUSIONS: MUA can improve mobility after PKS, whereby MUA seemed to be a functional therapy option for PKS. Compared to the control group, the MUA group showed lower functional values and an increased experience of pain. A correlation between prosthesis malalignment and MUA could not be detected radiologically. Further studies are necessary to investigate the reasons for PKS.

Can an acute high-grade acromioclavicular joint separation be reduced and stabilized without surgery? A surgeon's experience.

INTRODUCTION: While the management of Rockwood type III injuries is still a topic of debate, high-grade Rockwood type V injuries are mostly treated surgically, to anatomically reduce the acromioclavicular (AC) joint and to restore functionality. In this case report, we present a method for non-operative reduction and stabilization of a high-grade AC joint injury. CASE: A 31-year-old male orthopaedic resident sustained a Rockwood type V injury during a snowboarding accident. His AC joint was reduced and stabilized with an AC joint brace for six weeks. The brace provided active clavicle depression and humeral elevation. After removal of the brace the AC joint showed a nearly anatomic reduction. Six-month follow-up weighted X-ray views showed an AC joint which had healed in a Rockwood type II position and the patient returned to full pre-injury function with a satisfying cosmetic appearance. CONCLUSION: Non-operative reduction and stabilization of high-grade AC joint separations seems to be a valuable treatment option. A "closed reduction and external fixation" approach with the aid of a dedicated AC joint brace can reduce the AC joint and keep it in place until ligamentous consolidation occurs, thus improving AC joint stability and cosmetic appearance without surgical intervention.

Impact of Extremity Manipulation on Postural Sway Characteristics: A Preliminary, Randomized Crossover Study.

OBJECTIVE: Evaluate multisegmental postural sway after upper- vs lower-extremity manipulation. METHODS: Participants were healthy volunteers (aged 21-40 years). Upper- or lower-extremity manipulations were delivered in a randomized crossover design. Postural assessments were made pre-post manipulation, in floor and rocker board conditions. Analysis included traditional balance measures of pathlength and range and sample entropy (SampEn) to examine the temporal structure of sway of the head, trunk, and surface. RESULTS: No statistical changes in pathlength or sway range on the ground surface condition were observed. No increases in the amount of sway occurred in any condition. Chiropractic manipulation of either upper or lower extremities led to reductions in traditional measures of postural control on the rocker board. In the anteroposterior direction (sagittal plane), lower-extremity manipulation led to increased trunk SampEn while on the ground, and conversely a decreased SampEn while on the rocker board. In the mediolateral rocker board condition (frontal plane), manipulation elicited a change in SampEn that differed according to site of manipulation; upper-extremity manipulation increased SampEn, whereas lower-extremity manipulation reduced SampEn. CONCLUSION: Both upper- and lower-extremity manipulation influenced several measures of postural sway on both the ground and the rocker board. Lower-extremity manipulation improved the organization of sway at the trunk (anteroposterior direction) and the board (mediolateral direction). Given the reduction and reorganization of sway metrics seen in this study, we propose extending this line of research to the elderly who are at greatest risk of increased sway and falls.

Effects of Tibiofibular and Ankle Joint Manipulation on Hip Strength and Muscle Activation.

OBJECTIVES: The purpose of this study was to determine whether high-velocity, low-amplitude ankle region manipulations could increase force output and muscle activation of hip musculature in individuals with a history of ankle sprain and unilateral tensor fascia latae (TFL) weakness during muscle testing. METHODS: This investigation used a single-arm repeated measures design. Twenty-five participants' force outputs were tested at three time points (before manipulation, immediately after manipulation, and 48 hours after manipulation), and muscle activation of the rectus femoris, gluteus medius, and TFL was measured before and immediately after manipulation. Manipulations were applied to the talocrural, subtalar, proximal, and distal tibiofibular joints of the weaker limb. No contralateral manipulations were applied. Two-way repeated measures analysis of variance was used to compare maximal and average force production for each limb. In addition, paired t tests were used to compare muscle activation before and after manipulations. RESULTS: There was a significant limb × time interaction. The involved limb average force increased from before manipulation (65.7 N) to 48 hours after manipulation (77.8 N; P = .014), maximal force increased (76.9 N) 48 hours after manipulation (87.8 N; P = .030), and gluteus medius activation increased (9.8% maximum, 12.2% average) immediately after manipulation. No significant differences were found in the uninvolved limb. CONCLUSION: The results of this study suggest that high-velocity, low-amplitude ankle region manipulations might improve hip abductor strength in individuals with a history of ankle sprain and unilateral weakness during a TFL muscle test.

Treatment of Neck Pain With Myofascial Therapies: A Single Blind Randomized Controlled Trial.

OBJECTIVE: This study aimed to investigate the effects of myofascial release therapy vs a standard physical therapy program in patients with neck pain (NP). METHODS: This was a randomized controlled trial in which 54 participants with mechanical NP were randomly assigned into an experimental group (EG) or a comparison group (CG). The EG group (n = 27) received 5 therapy sessions of myofascial release therapy while the CG group (n = 27) received 10 sessions of massage, ultrasound therapy, and transcutaneous electric nerve stimulation over a 2-week period. Outcome measures were the numerical pain rating scale (NPRS), pressure pain thresholds (PPTs) and range of motion at the end of treatment and at 1-month follow-up. RESULTS: At 1-month follow-up, between-group differences in change scores were found in the NPRS (mean = -1.56, 95% confidence interval [CI] [-2.30 to -0.81]; P < .001), in the right thoracic PPT (mean = 0.35, 95% CI [0.03-0.66]; P = .031), and in both left (mean = 0.34, 95% CI [0.08-0.61]; P = .012) and right (mean = 0.29, 95% CI [0.04-0.54]; P = .026) suboccipital PPTs. The success rate was 63.0% in the CG and 92.6% in the EG. The number needed to treat was 3.38 (95% CI = 1.99-11.23). CONCLUSIONS: Myofascial release therapy could be better than a standard physical therapy program for improving pain and suboccipital PPTs in patients with NP. However, the difference between both treatments is less than the minimum detectable change of the NPRS.

A systematic review of pre-hospital shoulder reduction techniques for anterior shoulder dislocation and the effect on patient return to function.

PURPOSE: The majority of acute anterior shoulder dislocations are sustained during sports and wilderness activities. The management of acute dislocations in the pre-hospital setting is currently without guidelines based on the evidence. The study aims to assess the risk of acute complications in pre-hospital shoulder reduction and identify which pre-hospital reduction technique has the highest success rate in the published literature. METHODS: The involved databases were Allied and Complementary Medicine, CENTRAL, CINAHL, Cochrane Database of Systematic Reviews, Embase, Europe PMC, Ovid MEDLINE®, Pedro, Proquest, Trip, and World Health Organization International Clinical Trials Registry platform. Only original research of high methodological quality was included, which was defined by the recently developed assessment tool-assessing the methodological quality of published papers (AMQPP) and investigated the management of acute anterior shoulder dislocations in the pre-hospital setting. RESULTS: Two hundred and ninety-eight articles were identified and screened. A full text review was performed on 40 articles. Four articles published between 2015 and 2018 met the inclusion criteria. A total of 181 patients were included with the study duration ranging from 6 to 60 months. All studies reported zero immediate complication following pre-hospital reduction and there were no documented subsequent adverse events regardless of the technique used. Prompt resolution of neurological symptoms was observed following the early and successful pre-hospital reduction. First attempt success rate, when performed by skilled practitioners, ranged from 72.3% to 94.9%. CONCLUSION: Pre-hospital shoulder reduction appears to be a safe and feasible option when carried out with the appropriate expertise. A novel reduction technique adapted from the mountain medicine diploma course at the University of Paris North was found to have the highest first attempt reduction success rate of 94.9%. Other techniques described in the literature included Hippocratic, Stimson's, Counter-traction and external rotation with the success rates ranging from 54% to 71.7%.

Is the Denis Browne Splint a Myth? A Long-Term Prospective Cohort Study in Clubfoot Management using Denis Browne Splint Versus Daily Exercise Protocol.

The Ponseti technique is successful in idiopathic clubfoot management. However, the leading cause of relapse and recurrence is nonadherence to the Denis Brown bracing protocol. This necessitates more extensive soft tissue surgeries. Based on a detailed up-to-date search, we have found that no other studies provide such a modified Ponseti technique. This study is unique, as it depends on using specific stretching exercises instead of bracing during management. Between August 2009 and June 2019, a consecutive series of 194 isolated idiopathic clubfoot patients (251 feet) were included in this study. The mean follow-up was 93 months (range 72 to 146), mean 91.8 months. All patients underwent a clinical and functional assessment using the Laaveg-Ponseti score and radiological assessments. There were 132 boys (68.1%) and 62 girls (31.9%), a male-to-female ratio of 2:1. The mean age at initiation of treatment was 14.9 days. According to the Laaveg-Ponseti score, 51.7% yielded excellent results, 35.3% yielded good results, 11.55% yielded fair results, and 1.59% yielded poor results. Bracing noncompliance has been identified as a major cause for treatment failure. This presented exercise protocol not only eliminates the need for bracing and reduces the cost for the affected individuals but also provides excellent clinical and radiographic end results, comparable to the original treatment protocol using the Denis Brown brace.
