RESUMO
BACKGROUND: Standard supra-acetabular pin placement still needs fluoroscopic guidance, which is technically demanding for an untrained surgeon due to the unfamiliar fluoroscopic view and the risk of damaging some structures. The risks associated with the open technique without fluoroscopy have not yet been investigated, despite the palpable entry point and large bony corridor for rapid insertion in the limited time available for the management of unstable pelvic fracture patients. The aim of this study was to compare the open technique without fluoroscopy to the fluoroscopically assisted percutaneous technique for the positioning of supra-acetabular screws in cadavers without pelvic instability. MATERIALS AND METHODS: The open technique for half-pin placement was compared to standard fluoroscopic guidance in 16 hemipelves (8 cadavers). The open technique was first performed on one side in each cadaver after simple randomization, followed by standard fluoroscopic guidance on the other side. In the open technique group, a Schanz pin 5 mm in diameter and 200 mm in length was inserted in the area just above the anteroinferior iliac spine (AIIS) and aimed with a medial inclination of 20° and a cephalad inclination of 10-20° after a 2 cm pilot drill hole had been established. Standard fluoroscopically guided pin placement was performed on the other side. Fluoroscopic assessment was conducted after final pin placement on both sides. The lateral femoral cutaneous nerve of the thigh (LFCN) and the hip capsule were identified via the Smith-Peterson approach. After complete dissection of soft tissue, it was clearly apparent that pin penetration was conducted outside the bony corridor. RESULTS: The LFCN was found to be in a risk zone near the pin (mean distance, 15 mm; range, 0-30 mm). One LFCN may have been injured in the fluoroscopic guidance group. The mean medial inclination of the pin was 19.8° (range, 5-40°) and the mean cephalad inclination was 11.5° (range 0-20°) in the open technique group. The mean medial inclination of the pin was 30.4° (range, 20-45°) and the mean cephalad inclination was 19.3° (range, 2-35°) in the fluoroscopic guidance group. The mean distance of the pin entry point from the AIIS was 11.1 mm (range, 0-35 mm) in the open technique group. The mean distance of the entry point of the pin from the AIIS was 15.1 mm (range, 0-25 mm) in the fluoroscopic guidance group. The mean hip joint capsule distance was 12 mm (range, 8-25 mm). No joint penetration was observed in the open technique group, compared to one joint penetration in the fluoroscopic guidance group. No sciatic notch penetration was found in either group, but pin penetration outside the external cortex of the ilium was found only in the open technique group, in 4 hemipelves. CONCLUSIONS: This study shows that the freehand technique performed by experienced trauma surgeons may be as acceptable as controlled pin insertion under image intensification for selecting the proper entry point and stabilizing the anterior pelvic ring.

BACKGROUND: The purpose of this study was to report on ankle and foot functions via the holistic evaluations using clinical examination, functional scores assessment and isokinetic tests after harvesting autogenous peroneus longus tendons for anterior cruciate ligament (ACL) reconstruction focusing on the donor site morbidity with a minimum 1-year follow-up period. MATERIAL AND METHOD: The study included 24 patients who underwent ACL reconstruction using peroneus longus autograft and endobutton fixation. Results of ACL reconstruction were assessed via physical examination. Donor site morbidity of the foot and ankle after tendon-harvesting was assessed using American Orthopedic Foot-and-Ankle Society (AOFAS) for ankle-hindfoot score and Visual Analogue Score-Foot Ankle (VAS-FA). Isokinetic testing for the ankle was performed in 10 voluntary patients after surgery. RESULTS: Mean follow-up time was 12.8 months. Regarding the latest follow-up, anterior drawer tests of ankle showed normal findings in 83.3%, and 1+ anterior laxity in 16.7% of all patients. Mean pre- and postoperative AOFAS scores were 100.0 ± 0.0 and 96.0 ± 9.6, respectively at 6-month follow-up (p = 0.06). Mean pre- and postoperative VAS-FA scores were 99.7 ± 1.1 and 95.4 ± 12.0, respectively at - 13-month follow-up (p = 0.09). At 7-month follow-up by isokinetic testing, peak torques of eversion and inversion were significantly lower on the harvested ankle compared with the contralateral ankle at both velocities (60 degrees/second and 120 degrees/second, p < 0.05). CONCLUSION: Based on overall findings in the present study, the authors could not recommend the peroneus longus tendon as the first option of donor graft for ACL reconstruction due to the several morbidities particularly in the first 12 months after the operation. However, the peroneus longus tendon may be the option after other graft harvestings for the ligament reconstruction, which needs several tendon grafts in a patient with multi-directional instability of the knee due to some specific situation such as a traumatic knee dislocation.

BACKGROUND: Deltoid splitting is one of common and useful approaches in proximal humerus surgery. The disadvantage of this approach is high risk of axillary nerve injury. Nowadays, there is no consensus in the proper mean of the individual's axillary nerve location. OBJECTIVE: The present study aim to determine the correlation between the axillary nerve and the upper arm length that may create equations to calculate the nerve location. MATERIAL AND METHOD: Seventy shoulders were measured the distance from lateral acromial edge to axillary nerve and compared with upper arm length in three positions of the shoulder (adduction 30°, abduction 45° and 90°). The authors used distance of lateral acromial edge to lateral epicondyle and tip ofgreater tuberosity to lateral epicondyle as the upper arm length. RESULTS: The average distance ofshoulder adduction 30°, abduction 45° and90° were 57.9, 57.1 and 52.9 mm, respectively. All of three positions showed linear correlation to upper arm length from both of reference sites. From acromion edge reference, where "Y" is axillary nerve distance in mm and "x" is upper arm length in cm, the relation were Y= 2.3x-10, Y= 2x-2 and Y= 2x-7with the accuracy rate were 88.57%, 85.71% and 81.43%, respectively. From greater tuberosity reference, the relations were Y = 2.54x-14, Y = 2x and Y = 2.3x-12 with the accuracy rates 87.14%, 80% and 84.29%, respectively. CONCLUSION: There is linear correlation between distance from the lateral acromial edge to axillary nerve and the upper arm length. The authors can predict the danger zone in the location of the anterior upper branch of the axillary nerve. However, further clinical study may helpful to prove the equations. Level ofevidence: Basic science anatomy study.

Fluoroscopy-guided injection via the anterior (A), anterolateral (AL), or proximal anterolateral (PAL) approaches are the common hip injection techniques without comparing the efficacy of the three techniques. The prospective randomized controlled trial was conducted from August 2020 to March 2022. Included patients with intra-articular hip disorders indicated an intra-articular steroid injection. Excluded significant spine pathology with radiculopathy or significant neurological deficits, previous hip surgery of the injection side, suspected tumor or infection origins, steroid or contrast media allergy, and body mass index > 35 kg/m2. The primary outcome was the injection attempt defining one attempt and multiple attempts. 90 patients were recruited and allocated to 30 per group. There were no differences between A, AL, and PAL respectively regarding the success in one attempt rate (80%, 80%, 90%; p = 0.533), VAS during local anesthetic injection (4.33 ± 1.99, 3.70 ± 2.34, 4.27 ± 2.49; p = 0.500), VAS during intra-articular injection (4.27 ± 1.87, 4.70 ± 2.37, 4.13 ± 2.37; p = 0.587), radiation doses (0.558 ± 0.313, 0.526 ± 0.485, 0.492 ± 0.275 mGy; p = 0.788), radiation time (0.043 ± 0.017, 0.039 ± 0.021, 0.041 ± 0.015 seconds; p = 0.723), and complications. The post-injection mHHS was improved in all three approaches without significant differences.

Medial patellofemoral ligament (MPFL) reconstruction is a standard procedure in patellar dislocation patients. Superficial quadriceps autografts (QA) and hamstring autografts (HA) are popular graft choices in MPFL reconstruction with the lack of directly compared clinical studies between both methods. A total of 43 patellar instability patients, who underwent QA and HA for patellar stabilization at a specified center between 2012 and 2021, were retrospectively reviewed. 21 QA and 22 HA patients were 52.4% of males and 47.6% females with a median age of 25 years (range 12-58) in the QA group, while 63.6% were females with a median age of 21 years (range 14-58) in the HA group. The mean follow-up period was 46.9 months (range 24-77) in QA and 61 months (range 24-100) in the HA group. At the final follow-up, no complications were observed with either technique. No patients presented with recurrent dislocations after surgery. There was no statistically significant difference in postoperative mean Kujala scores (QA = 94.9+/- 4.1 and HA = 94.2+/- 8.0, p = 0.73) or the mean Lysholm scores (QA = 94.1+/- 5.0 and HA = 93.2+/- 7.0, p = 0.61).

Background: The Jobe test is commonly used to diagnose full-thickness (FT) supraspinatus (SSP) tendon tear. The original Jobe test used single-arm testing, although the double-arm Jobe test has also been used in clinical practice. Purpose: To evaluate the reliability, accuracy, and diagnostic value of the single-arm and double-arm Jobe test for diagnosis of FT SSP tear. Study Design: Cohort study (diagnosis); Level of evidence, 2. Methods: Patients with shoulder pain requiring magnetic resonance imaging (MRI) of the shoulder between March 1, 2021, and March 31, 2022, were enrolled. Each patient underwent both single-arm and double-arm Jobe tests by 2 orthopaedic surgeons independently, and the presence of pain, weakness, or both during the test was documented. Diagnosis of FT SSP tear on MRI scan was used as the gold standard to compare the diagnostic value of the Jobe test. The interrater reliability of the Jobe test, and the inter- and intrarater reliability of the MRI evaluation (patients with vs without FT SSP tear) was performed using the kappa (κ) coefficient. Results: A total of 80 patients (57 females [71%]; mean age, 61.46 ± 9.61 years) were included. MRI scans revealed FT SSP tears in 32 (40%) of the patients. Both single- and double-arm Jobe tests had low diagnostic values (accuracy, 46.25% to 60%; sensitivity, 46.9% to 84.4%; specificity, 25% to 66.7%). The single-arm test with weakness revealed the highest sensitivity (84.4%). The double-arm test with weakness plus pain revealed the highest specificity (66.7%). Double-arm testing with pain had the highest accuracy (60%), with the highest positive likelihood ratio (1.5). The interrater reliability of the Jobe test indicated substantial agreement (double-arm vs single-arm, κ = 0.771 and 0.716, respectively, agreement 85%; P < .05). The interrater reliability of MRI scan evaluation of the FT SSP tear indicated substantial agreement (κ = 0.750, agreement 85%; P < .05), while the intrarater reliability indicated almost perfect agreement (κ = 0.917, agreement 96%; P < .05). Conclusion: The Jobe test, either single- or double-arm, had low accuracy and diagnostic value in diagnosing FT SSP tear. The concern with a single-arm examination for weakness is that it may be an inappropriate diagnostic test for ruling out FT SSP with 84% sensitivity, while a double-arm examination provides a higher specificity.
RESUMO
Background: The success rate of surgical treatment for rotator cuff (RC) tear ranges from 16% to 94%. The Rotator Cuff Healing Index (RoHI) is a system for predicting failure after RC repair and is based on a combined score of factors, including age, anteroposterior (AP) tear size, tendon retraction, fatty infiltration of the infraspinatus muscle, bone mineral density (BMD), and level of work activity. Purpose: To determine the factors leading to RC repair failure in a Thai population, to test the reliability of the RoHI in this population, and to compare the RoHI with a modified RoHI (m-RoHI) based on the factors for repair failure as determined. Study Design: Case-control study; Level of evidence, 3. Methods: This study included 133 Thai patients who underwent arthroscopic RC repair between February 2012 and February 2021. Postoperative magnetic resonance imaging was performed at 6 to 24 months to evaluate RC healing. Variables that might affect failure rates were evaluated, including demographic characteristics, AP tear size and retraction, radiographic measurements, and magnetic resonance imaging findings. The m-RoHI was created using factors that significantly predicted repair failure on multivariate analysis. The area under the receiver operating characteristic curve was calculated to determine the reliability of the RoHI and to compare the reliability of the RoHI and m-RoHI to predict failure rates. Results: Multivariate logistic regression analysis revealed that body mass index ≥23 (adjusted odds ratio [OR], 9.02; P = .034), high work activity (adjusted OR, 19.53; P = .008), AP tear size ≥2.5 cm (adjusted OR, 19.04; P = .001), and a retraction size of 2 to <3 cm (adjusted OR, 20.36; P = .013) were the independent factors that predicted repair failure in our population. BMD was not independently predictive of repair failure. We used these 4 significant independent factors to generate the m-RoHI. The area under the curve of the final adjusted m-RoHI was slightly improved as compared with the original RoHI, but this difference was not significant (0.827 [95% CI, 0.741-0.913] vs 0.780 [95% CI, 0.686-0.875], respectively; P = .447). Conclusion: The m-RoHI had a similar predictive value for repair failure to the original RoHI in our study population, but it did not require obtaining BMD. The m-RoHI may be useful in populations where BMD is not routinely obtained.
RESUMO
Background: The standard radiographic view for diagnosing acromioclavicular joint (ACJ) dislocations is the Zanca view of both shoulders to assess superior displacement of the distal clavicle by measuring the coracoclavicular distance (CCD) and comparing it with the uninjured shoulder; however, there is no consensus on a gold standard for diagnostic measures to classify acute ACJ injuries. Purpose: To compare the CCD from an upright chest radiograph with a standard Zanca view of both shoulders in patients with an ACJ dislocation. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: We reviewed the records of 70 patients with an ACJ dislocation between 2010 and 2021 who had both an upright chest radiograph and a Zanca view. An ACJ dislocation was classified as low grade (Rockwood types 1-3) or high grade (Rockwood type 5). The CCD was measured on the upright chest radiograph and the Zanca view by 2 independent reviewers, and the percentage of the CCD difference compared with the unaffected side (ΔCCD) was calculated and compared between the upright chest radiograph and the Zanca view. Interrater and intrarater reliability were determined using the intraclass correlation coefficient. Results: Included were 70 patients (55 male and 15 female; mean age, 46 years). There were 29 patients (41.43%) with a low-grade injury and 41 patients (58.57%) with a high-grade injury. In the overall analysis, the ΔCCD on the upright chest radiograph and Zanca view was significantly different (130.25% ± 88.42% vs 152.69% ± 106.56%, respectively; mean difference, 22.44% [95% CI, 2.40% to 42.48%]; P = .029). The subgroup analysis revealed that the ΔCCD on the upright chest radiograph and Zanca view was significantly different for patients with a low-grade injury (60.71% ± 25.79% vs 91.46% ± 68.54%, respectively; mean difference, 30.76% [95% CI, 7.18% to 54.33%]; P = .012) but not different for patients with a high-grade injury (179.45% ± 83.87% vs 196.00% ± 107.97%, respectively; mean difference, 16.56% [95% CI, -14.06% to 47.18%]; P = .281). The intraclass correlation coefficients for the ΔCCD measurements indicated good to excellent interrater and intrarater reliability. Conclusion: The study findings indicated that upright chest radiography can be used as a diagnostic screening tool for high-grade ACJ dislocations, but not for low-grade ACJ injuries, compared with the Zanca view.
RESUMO
Subacromial corticosteroid injections (SCI) treat shoulder pain from subacromial impingement syndrome (SIS). However, a high-volume corticosteroid injection (HVCI) increases the incidence of local and general complications from lidocaine. This study aimed to compare the results of functional and clinical outcomes between the very low-volume corticosteroid injection (VLVCI) and HVCI including to WORC (Western Ontario Rotator Cuff Index), VAS (Visual Analog Scale), DASH (The disabilities of the arm, shoulder, and hand) and ROM (Range of Motion). A total of 64 patients presenting with SIS were evaluated in two SCI volume in a randomization-controlled trial study. The VAS for pain pre-injection and post-injection at 15 min, was from 5.34 ± 2.44 at before injection to 2.44 ± 1.58 at post injection 15 min in the HVCI group (P < 0.001) and from 5.19 ± 2.33 to 2.84 ± 1.49 in VLVCI group (P < 0.001). Not significant differences at mean difference VAS post-injection 15 min VAS (P = 0.324) and Percentage difference VAS pre-injection and post-injection (P = 0.24). All follow-up timing, there were no significant differences in WORC, DASH and ROM between two groups (P > 0.05). The results revealed the VLVCI is non-inferior to HVCI both of functional outcomes and VAS.

Chronic osteomyelitis is still a serious health problem that causes disabling conditions and has an impact on the quality of life. The objective of this study was to determine the clinical efficacy and safety of localized antibiotics delivery via impregnated microporous nanohydroxyapatite (nHA-ATB) beads for chronic osteomyelitis treatment. A total of 62 patients were enrolled in this study. After radical surgical debridement, the bone defect was filled with three types of antibiotics (vancomycin or gentamicin or fosfomycin) impregnated HA beads. The follow-up period was 48 weeks. It was found that the success rate was approximately 98% with a re-infection in only one patient. Quality of life of all patients after treatment improved significantly over time. Systemic exposure to vancomycin and gentamicin after beads implantation was limited and high local antibiotics concentrations were found in wound drainage fluid at 24, 48 and 72 h. Blood biochemistry measurements did not show any nephrotoxic or hepatotoxic effects. 20 adverse events were reported, but 90% of the events were resolved without having to remove the beads and the patients recovered. Satisfactory outcomes were observed in terms of success rate, quality of life and adverse effect. nHA-ATB beads impregnated by vancomycin or gentamicin or fosfomycin could potentially be employed as an alternative product of choice for localized antibiotics delivery in chronic osteomyelitis treatment.
RESUMO
The current concept procedures in the acute acromioclavicular joint dislocation should be divided into 2 types of structure restoration: those that provide coracoclavicular stabilization, which affects the primary healing of the coracoclavicular ligaments by vertically stabilizing the clavicle and coracoid in their anatomical positions, and those that attempt to repair the superior acromioclavicular ligament complex, which controls both horizontal and rotational stabilization. The acute acromioclavicular joint dislocation clinical outcome will be achieved if you perform both procedures. It's difficult to stabilize the acromioclavicular joint in both vertical and horizontal planes, and most current techniques aren't always effective. In this Technical Note, we discuss an arthroscopic-assisted technique that reconstructs the coracoclavicular and acromioclavicular ligaments under image intensifier guidance to achieve bidirectional (vertical and horizontal) and rotational stability.
RESUMO
End-stage renal disease with spontaneous quadriceps tendon rupture (QTR) is a specific condition that differs from classic QTR. The tissue quality of the quadriceps tendon (QT), the rupture site, the mechanism of injury, and the pathophysiology of the rupture mechanism all have an effect on conventional QT repair procedures, with a higher likelihood of rerupture or failed repair construction. We believe that our technique provides repair-site stability, strong repair construction, increased contact surface healing, and a reduced chance of rerupture after QT repair. Furthermore, in most patients who have end-stage renal disease with QTR, misdiagnosis and/or underestimation occurs, resulting in proximal retraction of the QT and poor results; however, this technique can be performed with alternative procedures such as augmentation or QT lengthening. The suture bridge transosseous QT repair technique relies on biomechanics knowledge for better stability. Suture bridge repair concept can achieve better healing of all layers of the QT until returning to normal activity with no disability and an improved quality of life.
RESUMO
BACKGROUND: Os acromiale is an anatomic variant in which the acromial ossification center fails to fuse. It may lead to painful shoulder conditions and surgical intervention may be required for treatment. The prevalence of os acromiale in South Koreans (0.7%) has previously been the representative number for the Asian population, and it is lower than that in the Black and White populations. PURPOSE: To determine the prevalence of os acromiale in Thai patients with shoulder disabilities who underwent magnetic resonance imaging (MRI). STUDY DESIGN: Cross-sectional study; Level of evidence, 3. METHODS: We retrospectively reviewed the MRI scans of patients with shoulder disabilities between January 2019 and May 2021 at a single institution. The relationship of sex, age, and shoulder diagnosis to the presence of os acromiale was then analyzed. RESULTS: A total of 940 MRI scans in 848 patients were evaluated, of which 20 shoulders were detected to have os acromiale, a prevalence of 2.13%. The mean age of the patients was 60.25 years, with 60% being female and 40% male. Of the 20 os acromiale cases, 17 (85%) were preacromiale, 1 (5%) mesoacromiale, and 2 (10%) meta-acromiale. The associated diagnoses were as follows: 75%, full-thickness rotator cuff (RC) tear; 10%, partial-thickness RC tear; 5%, RC tendinopathy with symptomatic os acromiale; 5%, anterior shoulder instability with full-thickness RC tear; and 5%, frozen shoulder. Age, sex, and associated shoulder disability were not associated with the presence of os acromiale. CONCLUSION: In Thai patients with shoulder problems who required MRI evaluation, the prevalence of os acromiale was 2.13%. This is lower than the prevalence from other ethnic groups but slightly higher than that from the same ethnic group (Korea). There was no relation between the presence of os acromiale and shoulder pain, regardless of diagnosis.
RESUMO
The acromiohumeral interval (AHI) is a measurement used to determine the superior migration of the humeral head in rotator cuff (RC) tear patients. The purpose of this study was to compare the AHI of; supine, upright shoulder radiographs, and magnetic resonance imaging (MRI) of the shoulder. The 86 shoulders were divided into 3 groups that included; (1) non-full thickness tear (50%), (2) full thickness (FT) tear ≤3 cm (33.7%), and (3) FT tear > 3 cm (16.3%). The mean difference of AHI noted was significantly lower in the supine radiographs and MRIs than with the upright (1.34-1.37 mm, 1.62-1.87 mm, respectively). Upright AHI ≤ 7.0 mm had 27.9% sensitivity and 100% specificity in diagnosing FT tears with 64% accuracy (p < 0.001). The supine AHI ≤ 6.5 mm had 32.6% sensitivity, 100.0% specificity, and 66.3% accuracy (p < 0.01). The results revealed the AHI in supine radiographs were significantly lower than upright shoulder radiographs. For AHI ≤ 7 mm in upright shoulder radiographs, this remains as an appropriate diagnostic test for ruling in shoulders with full thickness rotator cuff tears. This value was not relevant for use as the cut point in the supine radiographs and MRIs.

Background: The modified Harris Hip Score (mHHS) is one of the more commonly used patient-reported outcome measures to evaluate and monitor treatment in patients with hip abnormalities and has been translated into several languages. Purpose: To develop a Thai version of the mHHS (TH-mHHS) and evaluate the validity and reliability of the measure. Study Design: Cohort study (diagnosis); Level of evidence, 3. Methods: The TH-mHHS was developed using the forward-backward translation method. Patients who presented with hip pain during the first clinic visit completed the Thai version of questionnaires including the mHHS, 36-item Short Form Health Survey (TH-SF36), and Hip disability and Osteoarthritis Outcome Score (TH-HOOS). The validity between the measures was tested using the Spearman correlation coefficient. The test-retest reliability of the TH-mHHS was assessed using the intraclass correlation coefficient, and internal consistency was assessed using the Cronbach alpha. Results: A total of 64 patients were enrolled who had a mean age of 52.8 ± 16.6 years (range, 17-80 years). There were 64% female and 36% male participants. The TH-mHHS showed a moderate correlation with all subscales of the TH-HOOS and the total TH-HOOS (r = 0.50-0.65; P < .01) and a high correlation with the physical functioning subscale and physical component summary of the TH-SF36 (r = 0.73 and 0.75, respectively; P < .01). The test-retest reliability was excellent, with an intraclass correlation coefficient of 0.95 (95% CI, 0.92-0.97; P < .001). The internal consistency was acceptable, with a Cronbach alpha of .71. No floor or ceiling effects were observed. Conclusion: The TH-mHHS showed a moderate to high correlation with the TH-SF36 and TH-HOOS, excellent test-retest reliability, and acceptable internal consistency. This measure can be effectively used for evaluating Thai patients with hip disorders, especially an older and arthritic population.
RESUMO
BACKGROUND: Arthroscopic rotator cuff repair is the standard treatment in patients with symptomatic reparable rotator cuff tear. It brings good to excellent postoperative outcomes. Postoperative suction drainage is the method to theoretically reduce postoperative shoulder swelling and hematoma formation, which is still commonly used in clinical practice, yet its efficacy remains unproven. METHODS: This is a nonblinded prospective randomized controlled study. A sample of 43 shoulders were simply randomized without replacement across drain and nondrain groups, allocated by sealed envelope before skin closures. The preoperative, intraoperative, and postoperative data were analyzed. The difference of oblique (O) and horizontal (H) shoulder circumference between before and after operation is the primary parameter indicating swelling and hematoma formation. The preoperative reliability of O and H dimensions were evaluated by 2 independent evaluators. The visual analog scale, estimated blood loss, and Disabilities of Arm, Shoulder, and Hand score were analyzed. RESULTS: There was no significant difference of circumference between drain and nondrain groups in both O and H methods. For method O, the mean difference between drain and nondrain groups at 24 hours was -0.25 (95% CI: -2.09 to 1.59, P = .783), at 1 week was -0.54 (95% CI: -2.05 to 0.96, P = .470), at 1 month was -0.39 (95% CI: -2.06 to 1.28, P = .639) and at 3 months was -0.01 (95% CI: -1.49 to 1.46, P = .987). Method H: Mean difference between groups at 24 hours was 0.29 (95% confidence interval [CI]: -0.61 to 1.20, P = .520), at 1 week was 0.004 (95% CI: -0.99 to 1.002, P = .993), at 1 month was -0.53 (95% CI: -1.62 to 0.56, P = .333), and at 3 months was -0.07 (95% CI: -0.91 to 0.77, P = .862). The preoperative O and H parameters showed strong to almost perfect agreement (intraclass correlation coefficient for A = 0.858 [95% CI: 0.738 to 0.923, P < .001], intraclass correlation coefficient for B = 0.955 [95% CI: 0.918 to 0.976, P < .001]). No significant difference of visual analog scale, estimated blood loss, and Disabilities of Arm, Shoulder, and Hand score was recorded between groups. CONCLUSION: No difference was found between drain and nondrain placement for shoulder swelling, visual analog scale, estimated blood loss, and functional outcome in 3 months after surgery. Drain placement after arthroscopic rotator cuff repair is of unproven benefit in routine clinical practice.
RESUMO
Patellofemoral instability is one of the knee problems that can be found in up to 3% of knee injuries, especially in younger aged females. Recent biomechanical studies showed that the main soft tissue stabilizer for patellofemoral stability is the medial patellofemoral ligament (MPFL). More than 200 articles on MPFL reconstruction have been published. Some surgical techniques create multiple holes in the patellar area that may increase the risk of patellar fractures. This technique that we present here attempts to reduce the chance of patella-related complications, while maintaining stability of the reconstructed construct, reducing the use of a lengthy tendon graft within the patella and covering the footprint at the border of the patella closed to the native anatomy of the MPFL.
RESUMO
Proximal tendinopathy of the long head of the biceps (LHB) is a common shoulder problem that requires surgical intervention, especially in patients with concomitant rotator cuff tears. The comparative results of biceps tenotomy and biceps tenodesis are still doubtful; both techniques show good to excellent results in terms of postoperative pain and functional outcomes. The described technique-all-arthroscopic LHB transfer-is an optional biceps tenodesis technique using all-arthroscopic soft-tissue tenodesis and arthroscopic suturing of the LHB to the short head of the biceps and coracoacromial ligament combined with release of the LHB from the bicipital groove.
RESUMO
BACKGROUND: A hooked acromion on an outlet view and a keeled acromion on Rockwood tilt radiographs are associated with rotator cuff tears. The identification of the acromial morphology may be helpful for acromioplasty planning with regarding the acromial types. METHODS: Descriptive Laboratory Study. Three-dimensional computed tomography scans models of 108 shoulders in 91 patients with; (1) Normal shoulders, (2) Shoulders with osteoarthritis, and (3) Irreparable rotator cuff tears; were created and adjusted manually to provide the proper supraspinatus outlet and Rockwood views. The acromial morphology/spurs were analyzed, classified and tested for reliability. RESULTS: The intra-observer reliability of supraspinatus outlet view had a weak-to-strong agreement [0.828 (95%CI: 0.716-0.945, p-value<0.001), and 0.475 (95%CI: 0.288-0.672, p-value<0.001 from 2 evaluators]. The inter-rater of the supraspinatus outlet view has a minimal-to-moderate agreement [0.782 (95%CI: 0.662-0.907, p-value<0.001), and 0.344 (95%CI: 0.157-0.539, p-value<0.001) in the first and second readings]. The intra-observer reliability of the Rockwood view has a moderate-to-almost-perfect agreement [0.752 (95%CI: 0.652-0.860, p-value<0.001), and 0.903 (95%CI: 0.833-0.974, p-value<0.001) from 2 evaluators]. The inter-observer reliability of the Rockwood view has a moderate-to-strong agreement [0.854 (95%CI: 0.777-0.936, p-value<0.001), and 0.737 (95%CI: 0.634-0.847, p-value<0.001) in the first and second readings]. CONCLUSION: The classification of acromion morphology under Three-dimensional computed tomography in the supraspinatus outlet view has poor reliability. The Rockwood caudal tilt view model results in moderate-to-almost-perfect reliability that can be developed to the plain radiographic classification to determine the need for acromioplasty in rotator cuff surgery.
RESUMO
BACKGROUND: Anterior cruciate ligament (ACL) reconstruction is the mainstay treatment for the symptomatic anterior cruciate ligament insufficiency. Postoperative rehabilitation is the key main factor in successful surgical outcome but, the postoperative pain is a major obstacle to achieve good postoperative rehabilitation. The purpose of this study is to compare the effects of intra-articular morphine (IAMO) with normal saline [control group (C)] for postoperative pain control in the ACL reconstruction knees. METHODS: Patients who underwent ACL reconstruction during 2017-2019 were included, prospectively, from Khon Kaen hospital and randomized into 2 groups: IAMO group and the control group (C). After surgery, all patients received the same rehabilitation protocols. The results were assessed using the visual analogue scale (VAS), following the spinal block anesthesia at 6, 12,18 and 24 hours. Time to first analgesic request, range of motion and adverse effects were recorded. RESULTS: Forty patients were included and twenty were designated to the IAMO group. The mean age was 25.3±7.6 years and 80 percent of the patients were males. The IAMO group had lower VAS scores at the 12 and 24 hour postoperative periods [greatest variance at 12 hours (4.7±1.7 vs 5.8±1.6)]. In the IAMO group, time to first analgesic request was longer and morphine consumption was less, but these were not statistically significant. No complications were observed in both groups. CONCLUSIONS: The trend of VAS in the IAMO group was lower than in the control group, especially at 12 hours after surgery with no statistically significant differences. From this study and with the advantages of IAMO after ACL reconstruction, IAMO is useful in ACL reconstruction patients without complications.
