Ultrasound guided versus blinded injection in trigger finger treatment: a prospective controlled study.

BACKGROUND: Trigger finger is a common disease with a lifetime prevalence of 2%. One of the frequently preferred non-surgical treatments is blinded injection around the A1 pulley. This study aims to compare the clinical results of ultrasound-guided and blinded corticosteroid injection in the trigger finger. METHODS: In this prospective clinical study, 66 patients who had persistent symptoms of a single trigger finger were included. Patients with similar baseline characteristics such as age, gender, triggering period, and comorbidities were randomized. 34 patients had ultrasound-guided (UG), and 32 had blinded injections (BG). QDASH, VAS, time to return to work, and complications were compared between the groups. RESULTS: The mean age was 52,66 (29-73) years. There were 18 male and 48 female patients. In the UG, the triggering resolved faster, returning to work was earlier, and the medication period was shorter (p < 0.05). A total of 17 patients who had diabetes mellitus received re-injections, 11 of which were in BG and 6 in UG (p < 0.05). Although statistically significantly lower scores were obtained in UG at the 1st and 4th weeks in the QDASH and VAS scores (p < 0.05), at the 12th and 24 weeks, there was no significant difference (p > 0.05). CONCLUSION: Using ultrasound guidance for corticosteroid injections is more effective for treating trigger fingers than the blinded method, leading to better results and a faster return to work in the early stages of treatment.

Ultrasonography view for acute ankle injury: comparison of ultrasonography and magnetic resonance imaging.

INTRODUCTION: We aim to asses the diagnostic performance of ankle ultrasonography in patients presenting with acute ankle sprain injury, with comparison to MRI (Manyetik Rezonans Imaging). MATERIALS AND METHODS: The study included patients who applied to the hospital within 48 h after an ankle sprain, and who presented with signs of pain, swelling, and tenderness in the ankle. Ankle ultrasonography examination was performed and an ankle MRI took place the same day. RESULTS: 30 patients were included in the study. 53.3% (n = 16) were female. The mean age was 30 ± 6.4 years. The ultrasonography examination determined 76.6% (n = 23) of the patients to have anterior talofibular ligament (ATFL) injury, 33.3% to have (n = 10) CFL injury, and 33.3% to have (n = 10) anterior inferior tibia-fibular ligament (AITFL) injury. The MRI of the patients determined 73.3% (n = 22) of the patients to have ATFL injury, 43.3% (n = 13) to have calcaneal fibular ligament (CFL) injury, and 33.3% to have (n = 10) AITFL injury. The ATFL, CFL, and AITFL injuries diagnosed on ultrasonography correlated with the MRI results (ICC = 0.875, ICC = 0.879, and ICC = 0.858). However, among the ATFL injuries observed on MRI, 26.6% (n = 8) were grade I, 26.6% (n = 8) were grade II, and 20% (n = 6) were grade III injuries. Of the ATFL injuries observed on ultrasonography, 46.6% (n = 14) were grade I, 8.6% (n = 2) were grade II, and 30.4% (n = 7) were grade III injuries. CONCLUSIONS: Findings on all types of ATFL, CFL and AITFL appear to have a higher degree of correlation. Ultrasonography could have an added role as a triaging tool, to fast-track MRI.

Comparison of the radiological parameters between dynamic-referencing tactile guidance robotic system and Microplasty® instrumentation in unicompartmental knee arthroplasty.

OBJECTIVES: This study aims to compare the radiological outcomes of unicompartmental knee arthroplasty (UKA) performed by a navigation-based robotic system versus Microplasty® instrumentation. PATIENTS AND METHODS: Between January 2018 and January 2019, a total of 90 knees of 75 patients (65 males, 10 females; mean age: 62.0±9.4 years; range, 50 to 73 years) were included. Among these, 54 knees underwent Oxford mobile-bearing UKA with an Microplasty® instrumentation set and 36 knees were operated with the aid of a Restoris® MCK with MAKO navigation-based robotic system. Postoperative anteroposterior and lateral X-rays of all patients were evaluated according to nine different parameters. On the femoral side, femoral varus-valgus angle, flexion-extension angle, femoral condyle posterior fit; on tibial side, tibial component varus/valgus, tibial posterior slope, medial, anterior, posterior and lateral fit of tibial component assessed. RESULTS: There was no significant difference between groups in terms of age, sex, and affected side. On the femoral side, no significant difference was observed in the component position between groups. On the tibial side, tibial component medial fit (p=0.032) and anterior fit (p=0.007) were better in navigation-based robotic system group. CONCLUSION: Microplasty® instrumentation may lead to comparable implant positioning compared to a tactile-based navigated robotic instrumentation.

Does the clamping method in local and systemic TXA applications in total knee arthroplasty change the game?: A retrospective comparative cohort study.

Many different methods and drain clamping periods have been described in systemic and local tranexamic acid (TXA) applications, and the superiority of the methods to each other has not been clearly demonstrated. The method of local infusion in combined TXA applications may not alter the Hb drop or total or hidden blood loss. We aim to compare two different combined TXA application methods. We retrospectively analyzed 182 patients who underwent total knee arthroplasty between 2018 and 2021. Patients over 40 years of age who underwent TKA for degenerative knee arthritis were included in the study. Unicondylar, revision, or bilateral arthroplasties and patients with the cardiovascular or cerebrovascular disease were excluded from the study. All patients in the study received 1 g TXA intravenously half an hour before the incision. For the first group, 1 g TXA was given intra-articularly at the drain site after closure, and the clamp was kept closed for 1 hour. In the second group, the drain was clamped for an additional 6 hours, and a 1 g intravenous dose was administered at the 5th hour postoperatively. No local applications were used in the control group. Total, hidden, and visible blood loss (total blood loss, hidden blood loss, visible blood loss), postoperative decreases in hemoglobin and hematocrit level (ΔHgb, ΔHtc), blood transfusion rates, and hospital stay durations were evaluated. There were 72 patients in the first group, 52 in the second, and 58 in control. A total of 37 patients received one or more blood transfusions postoperatively, and there was no statistical difference in the need for blood transfusions between the groups (P = .255). Although a statistically significant difference (P = .001) in total blood loss, hidden blood loss, visible blood loss and ΔHgb values was observed between the groups, the difference between the first and second groups was insignificant (P = .512). The duration of hospital stay was observed to be less in the first and second groups (P = .024). Local and systemic TXA applications were observed to be more effective than only systemic applications in reducing blood loss after total knee arthroplasty, regardless of the local method.

The effects of patient related factors on hidden and total blood loss in single-level open transforaminal lumbar interbody fusion surgery.

OBJECTIVE: The aim of this retrospective study was to identify the amount of TBL and HBL and analyse the risk factors using multivariate linear regression analysis during single-level OTLIF surgery. METHODS: In this study 62 patients (32 male, 30 female, mean age 49.22 ± 13.26) who underwent single-level interbody fusion proce dures by a single surgeon between 2015 and 2021 were included. Retrospectively, relevant statistics regarding body mass index (BMI), American Society of Anesthesiologist Score (ASA), preoperative mean arterial pressure (MAP), and age were gathered. Preoperative MR images were used to assess and measure radiological parameters such as skin-disc distance (SDA), canal area (CA), paravertebral muscle area (PVMA),lumbosacral maximum subcutaneous fat thickness (LSMSF), operation level subcutaneous fat thickness (OPSF) and spi nous process length (SPL).Total blood loss (TBL) was calculated according to Nadler's formula. Hidden blood loss (HBL) was measured by deducting the measured (visible) blood loss from TBL. TBL, HBL and their relationship with preoperative parameters were assessed. RESULTS: HBL was determined to be significantly higher in older patients (P = 0.012). MAP was seen to have a statistically significant cor relation with operating time (P = 0.002), operative bleeding (P = 0.002), TBL (P = 0.006), and HBL (P = 0.001), and an inverse correlation with postoperative drainage (P = 0.007). The ASA scores were observed to be statistically significantly correlated with TBL (P = 0.001), and HBL (P = 0.001). LSMSF showed a significant correlation with TBL (P = 0.005) and HBL (P = 0.002). OPSF was determined to be correlated with TBL (P = 0.011), HBL (P = 0.009) and length of stay in hospital (P =0.034). SDD was correlated with TBL (P =0.043), and SPL with HBL (P = 0.013). It was shown that age (P =0.012), MAP (P =0.001), ASA (P =0.001), LSMFS (P = 0.002), OPSF (P = 0.009), SPL (P = 0.013) were risk factors for HBL. According to multivariate logistic regression analysis; two anatomical factors LSMSF and SPL were independent risk factors for HBL (P < 0.05). CONCLUSION: This results of this study have revealed that most patient-related parameters have a significant effect on HBL and TBL.The study has also demonstrated that LSMSF and SPL are independent risk factors for HBL.

Treatment Of Ingrown Toenail with a Minimally Invasive Nail Fixator: Comparative Study with Winograd Technique.

BACKGROUND: Many surgical techniques have been reported for the treatment of ingrown toenails. Occurrences of infection after matricectomy procedures could cause clinicians to prefer using external braces to treat ingrown toenails. This study compares patients with ingrown toenails who underwent the nail fixation technique and the Winograd technique. METHODS: Patients who underwent ingrown toenail surgery were retrospectively reviewed. The patients' demographic characteristics (age, gender, body mass index [BMI] morphology according to Heifetz classification, surgical technique, visual analog scale (VAS) values, time to return to daily activities (days), complications, and satisfaction levels were all recorded. RESULTS: Seventy patients were included in the study. Of the patients, 33 underwent nail fixation and 37 underwent the Winograd technique. No significant statistical differences were found in terms of patients' age, gender, BMI, preoperative clinical features, long-term satisfaction, and ingrown toenail recurrence rates between the two groups, but time to return to daily activities and VAS values were statistically significantly lower in patients treated using nail fixation compared with the Winograd technique. CONCLUSION: Nail fixation can be an effective surgical treatment option for an ingrown toenail.

The intra- and interobserver reliability of five commonly used intertrochanteric femur fracture classification systems.

OBJECTIVES: This study aims to evaluate the effect of surgical experience on reliability for Boyd-Griffin, Evans/Jensen, Evans, Orthopaedic Trauma Association (main and subgroups), and Tronzo classification systems. PATIENTS AND METHODS: Between January 2013 and December 2014, radiological images of a total of 60 patients (13 males, 47 females; mean age: 78.9±21.9 years; range, 61 to 96 years) with the diagnosis of intertrochanteric femur fracture were analyzed. Radiographs were evaluated and classified by five residents and five orthopedics and traumatology surgeons according to the Evans, Boyd-Griffin, Evans/Jensen, OTA, and Tronzo classification systems. Intra- and interobserver reliability were calculated using the kappa statistics. RESULTS: The worst intraobserver compatibility among the residents was the classification system with OTA subgroups (κ=0.516), while the classification system with the best intraobserver fit was found to be OTA main groups (κ=0.744). The worst agreement among surgeons was in the Evans classification system (κ=0.456). However, the best intraobserver agreement was in the OTA main groups (κ=0.741). The best interobserver agreement was observed regarding the OTA main groups (κ=0.699). CONCLUSION: The classification that has the best harmony both among residents and surgeons, and between residents and surgeons is the OTA main group classification.

Comparison of Pain, Muscle Strength, and Functional Status Following Unicompartmental Knee Arthroplasty, Total Knee Arthroplasty, and Conservative Management of Gonarthrosis.

BACKGROUND: Treatment options and surgical decision for grade 3-4 gonarthrosis remains controversial. We aimed to compare the pain level, muscle strength, physical performance, lower extremity functions, and other physical activity levels between patients who underwent arthroplasty and those who received conservative management for grade 3-4 gonarthrosis. METHODS: This prospective analytical observational study was conducted in a tertiary referral hospital. A total of 30 unicompartmental knee arthroplasty (UKA) and 30 total knee arthroplasty (TKA) patients as two different study groups and 30 patients were treated conservatively as the control group were included. The rehabilitation and complication rates were recorded. The values of the range of motion, quadriceps diameter, were measured and also the isokinetic muscle strength, pick-up, repeated sit-to-stand, stair ascending and descending, straight-line walking, timed up and go, and 20-m walk tests, the knee injury and osteoarthritis-outcome-score (KOOS), the hospital for special-surgery-knee-score (HSS), and Oxford-Knee-Score (OKS) were performed. RESULTS: Postoperative rehabilitation and complication rates were significantly higher in the TKA group compared to the UKA group (p = 0.029 and p = 0.026, respectively). Six months after the treatment, the knee extension muscle strength value at 180°/s, knee flexion degree, total work flexion, stair ascending, VAS at night, all KOOS symptom, pain and daily function and total scores in the UKA group was significantly different than the TKA and the control groups (p < 0.001). Total work extension values, knee flexion degree, in the control group were found to be significantly higher than the TKA group (p = 0.033, p < 0.001, respectively). CONCLUSIONS: The UKA was significantly superior to TKA and conservative treatment concerning pain, muscle strength, and quality of life. LEVEL OF EVIDENCE: IIa.

The time from injury to surgery is an important factor affecting the mechanoreceptors at stump of torn anterior cruciate ligament.

INTRODUCTION: Restoration of proprioceptive function after anterior cruciate ligament (ACL) reconstruction is as important as mechanical stability. For this purpose, remnant of the torn ACL is the only source of nerve endings. Our aim in this study is to investigate the quantity of mechanoreceptors in the remnants ACL stumps in injured knees and to correlate that with the quantity in intact ACL in control cases. MATERIALS AND METHODS: 48 patients that underwent ACL reconstruction between January 2016 and December 2018 as study group and 20 knees of 10 fresh frozen cadavers that as control group included in the study. Remaining stumps from study group and native ACL from control group were collected and investigated with S100 immunostaining. The type and number of mechanoreceptors in standardized areas was determined. The correlation of number of mechanoreceptors and time to surgery after ACL rupture were evaluated. RESULTS: The free nerve endings (FNE) and total number of mechanoreceptors were significantly lower in the study group as compared to the control group (p < 0.001 and p = 0.004, respectively). The number of Golgi-Mazzoni corpuscle decreased significantly with time (p = 0.041 CC: - 0.438). CONCLUSION: The time from injury to surgery is an important factor affecting the mechanoreceptors at stump of torn ACL. The surgeon and patient should be aware of the fact that delay in surgery could lead to the loss of mechanoreceptors.

Increased acromiohumeral distance in a double-row arthroscopic rotator cuff surgery compared to a single-row surgery after 12 months.

BACKGROUND: Arthroscopic rotator cuff surgery is an effective treatment for rotator cuff tears with the considered use of double-row repair techniques becoming popular in the last decade. We aim to compare the effects of double- and single-row arthroscopic rotator cuff repairs (ARCR) on repair integrity (RI) and acromiohumeral distance (AHD). METHODS: In this observational study, we retrospectively identified 98 patients with degenerative rotator cuff tear treated with arthroscopic rotator cuff repair between 2016 and 2019. We excluded 22 patients with partial-thickness tears, 15 with associated subscapularis or SLAP tears, 13 with massive tears, and 5 patients lost to follow-up; we included 43 patients who had ARCR for full-thickness cuff tear and clinical, radiologic follow-up. Of these 43 patients, 23 are grouped as double-row repair group (DRG) and 20 as single-row repair group (SRG). A minimum of 12 months after the surgery, bilateral shoulder MRIs were obtained. Contralateral shoulders without asymptomatic rotator cuff tears served as a control group (CG). The operating surgeon and two other surgeons experienced in arthroscopy blindly measured the AHD and determined the RI at the control MRIs in all groups. Functional assessments relied on UCLA and qDASH Scores. RESULTS: The mean age was 57.89 (45-78) years, and the mean follow-up time was 28,65 (21-43) months. The mean AHD of the CG was 9.7 ± 0.96 mm, the preoperative AHD of DRG was 8.62 ± 1.45 mm, and SRG was 9.71 ± 0.95 mm. The postoperative mean AHD of DRG 9.61 ± 1.83 mm and SRG was 10.21 ± 1.97 mm. AHD differences between the preoperative and postoperative groups were significant (P=0.009). The increase of the AHD in the double-row group was significantly higher than the single-row group (P=0.004). There was a high correlation between the RI and DASH scores (P=0.005). RI did not correlate with the repair method (P=0.580). CONCLUSION: Although double-row repairs can maintain greater AHD than single-row repairs in the clinical setting, this difference did not affect functional results. Regardless of the surgical intervention, functional results are favourable if RI is achieved. LEVEL OF EVIDENCE: Level III, Retrospective Cohort Study.

Late Presenting Pediatric Radial Neck Fracture: A Case Report and Review of the Literature.

INTRODUCTION: A pediatric radial neck fracture, when the diagnosis is delayed, is still a challenging problem for the treating orthopedic surgeon. We report a pediatric patient with late presenting radial neck fracture and results of open reduction and fixation with Kirschner wires. CASE REPORT: A 13-year-old right-handed girl fell on an out-stretched right arm after being tackled during playing basketball and had a radial neck fracture. However, the diagnosis of her fracture was delayed for 3 weeks. At the first radiologic examination, the anteroposterior and lateral radiographs were showing over 80 degrees of angulation at the radial neck and subluxation of the radiocapitellar joint. We tried to obtain a closed reduction, but we could not succeed. Then, we performed open reduction while preserving medial periosteal continuity and vascular supply of the radial head by meticulous surgical dissection. Sixth-month radiography control and clinical examination confirmed the complete healing of the fracture without any epiphyseal injury. Painless full range of motion without any restriction of pronation and supination was achieved. The patient and her parents were satisfied with the outcome. CONCLUSIONS: Even if the diagnosis of pediatric radial fractures is delayed if we can preserve medial periosteal continuity and vascularity of the radial head with open reduction, satisfactory results are obtainable.

2,2'-Bipyridin-1-ium 3-nitro-benzene-sulfonate.

In the title compound, C(10)H(9)N(2) (+)·C(6)H(4)NO(5)S(-), the dihedral angle between the aromatic rings of the cation is 9.42 (7)°. In the crystal, the anions and cations are linked by C-H⋯O and N-H⋯O hydrogen bonds, generating R(2) (1)(5) and R(4) (4)(14) rings, respectively. These hydrogen bonds also provide packing along [110].

Diaqua-bis(ethyl-enediamine-κN,N')copper(II) 2,2'-dithio-dinicotinate sesquihydrate.

In the title compound, [Cu(C(2)H(8)N(2))(2)](C(12)H(6)N(2)O(4)S(2))·1.5H(2)O, there are two half-molecules of the cationic complex in the asymmetric unit. The Cu(2+) ions lie on inversion centres and are octa-hedrally coordinated by two ethyl-enediamine (en) and two aqua ligands in a typical Jahn-Teller distorted environment with the water O atoms in the axial positions. Two 2-mercaptonicotinate units (mnic) are linked by a disulfide bridge. All the ethyl-enediamine N-H and O-H groups form inter-molecular hydrogen bonds with acceptor O and N atoms, giving rise to a three-dimensional network. One of the uncoordinated water molecules has a site occupation factor of 0.5.
