Ultrasonographic Measurement of Median Nerve Cross-Sectional Area in Evaluating Carpal Tunnel Release Outcomes.

PURPOSE: Earlier research has explored carpal tunnel release (CTR) surgery outcomes using electrodiagnostic tests (EDX). However, evaluation of the median nerve before and after CTR by ultrasound (US) is understudied. This study aimed to establish the outcomes of CTR by EDX and US, and examine the correlation between the clinical improvement and US after CTR. METHODS: The sample consisted of 172 wrists that underwent CTR. Pain was assessed using the visual analog scale (VAS). The Boston Carpal Tunnel Syndrome Questionnaire (BCTQ), including the symptom severity and function subscales, was applied before and 3 months after CTR. The proximal and distal cross-sectional areas (CSAs) of the median nerve were measured using US, and EDX was performed before and 3 months after CTR. RESULTS: Patients had mean preoperative and postoperative VAS scores of 7.7 ± 1.2 and 1.7 ± 1.2, respectively. The mean preoperative and postoperative proximal CSA measurements were 16.4 ± 4.5 mm2 and 12.1 ± 3.9 mm2, respectively. The mean preoperative and postoperative distal CSA measurements were 13.6 ± 3.7 mm2 and 11.0 ± 3.1 mm2, respectively. A significant improvement was observed in VAS, BCTQ, and EDX 3 months after CTR. A weak, positive correlation was observed between the improvement in the BCTQ symptom severity and function subscales and CSAs following CTR. CONCLUSIONS: The results of this study demonstrate that preoperative median nerve CSA values may be used in evaluating CTR outcomes. TYPE OF STUDY/LEVEL OF EVIDENCE: Therapeutic IV.

Evaluation of Patients with Acromioclavicular Joint Separation Treated Using the Clavicular Hook Plate.

BACKGROUND: This study aimed to evaluate the outcomes of patients who underwent surgical treatment using the clavicular hook plate for diagnosed Rockwood Type 3 - Type 4 - Type 5 acromioclavicular joint separation. MATERIAL AND METHODS: Patients who were operated with the diagnosis of acute traumatic acromioclavicular joint separation between the years 2017-2021 were evaluated retrospectively. Patients' age, gender, mechanism of injury, time to surgery, follow-up duration, and complications were evaluated. Functional results were evalu-ated using pre-op and post-op VAS and the Constant-Murley Shoulder Score. RESULTS: A total of thirty patients admitted with the diagnosis of acromioclavicular joint separation were included. All patients underwent surgical treatment using the clavicular hook plate. Twenty (66.6%) patients were male and 10 (33.6%) were female. Seventeen of the patients were admitted due to sports injuries, 6 due to traffic accidents, and 7 due to workplace accidents. The patients were followed up for an average of 26.1 weeks. The Rockwood Classification was used for classification of injuries. Accordingly, 12, 13, and 5 of the patients had Type 3, Type 4, and Type 5 injury, respectively. While the mean pre-op VAS score was 7.4 (5-9), it was 1.8 (1-4) in the post-op period. The mean pre-op Constant-Murley score was 31.5 (22-42), compared to 85.1 (72-100) in the post-op period. The differences between the pre-op and post-op VAS and Constant-Murley Shoulder Scores were statistically significant. CONCLUSION: In this study, we achieved good functional results in the treatment of acromioclavicular joint separation by using a clavicular hook plate providing stable fixation and allowing early mobilization.

The Fate of Failed Debridement, Antibiotics, and Implant Retention in Infected Knee Arthroplasties: Nothing to Lose.

Purpose The frequency of periprosthetic knee infections increases yearly because of the popularity of the total knee prostheses. Revision knee arthroplasty is an annoying problem for both the surgeons and the patients. Debridément, antibiotics, and implant retention (DAIR) is a popular alternative for the treatment of periprosthetic knee infections. Little is known about the fate of the failed DAIR patients. This study aims to investigate the effect of the failed DAIR on the clinical result after two-staged revision arthroplasty. Method Ninety-nine two-staged revision arthroplasties and 85 DAIR patients from two reference clinics were retrospectively analyzed. The minimum follow-up was 36 months. Patients were grouped according to the treatment as, two-staged revision without DAIR, two-staged revision after failed DAIR, and successful DAIR. Their Knee Society Scores (KSS), functional KSS (KSS-f) and Western Ontario and McMaster Universities Arthritis Index (WOMAC) scores were analyzed and compared. Results DAIR has a 52.9% success rate for the treatment of infection. Elevated erythrocyte sedimentation rates and C-reactive peptide levels are not risk factors for failure, but the time passed since the index surgery is a risk factor for worse outcome scores. Failed DAIR is not a risk factor for reinfection after two-staged revision. Last KSS after failed DAIR, successful DAIR, and two-staged revision were 83.98±7.033, 91.89±4.386, and 91.38±4.735, respectively. Last KSS-f after failed DAIR, successful DAIR, and two-staged revision were 86.25±9.524, 94.56±8.106, and 94.85±5.996, respectively. Last WOMAC after failed DAIR, successful DAIR, and two-staged revision were 86.16±7.745, 94.750±4.964, and 93.319±5.961, respectively.  Conclusion Failed DAIR is associated with lesser, but still good, or excellent clinical scores. DAIR is suggested as a promising treatment option for periprosthetic knee infections in well-selected patients.

Quadriceps reconstruction with suture anchor and Achilles allograft combination in quadriceps tendon re-rupture after primary surgical repair: A novel technique.

Quadriceps ruptures are one of the pathological conditions of the knee extensor mechanism, accounting for 3% of all tendon injuries. These injuries cause substantial disability of the extensor mechanism. Primary repair is the treatment of choice in acute presentation. In the setting of chronic conditions, the treatment becomes more challenging. Available surgical options include lengthening procedures, and reconstruction with auto graft or allografts. The traditional Scuderi and Codivilla techniques are challenging to perform in degenerative or traumatic retracted ruptures. There is no standard effective treatment in these patients, which yields the best clinical and biomechanical outcomes. An 18-year-old male patient with quadriceps re-rupture after a primary repair was managed with allograft reconstruction using suture anchors. At six years of follow-up, the patient gained a full range of motion with excellent clinical outcomes. He returned to his previous work. In conclusion, quadriceps reconstruction using suture anchor and Achilles allograft combination is a feasible technique in neglected cases who present with quadriceps tendon re-rupture after primary surgical repair.

Comparison of rapid and conventional methods for investigating of mecA presence in Staphylococcus Species.

OBJECTIVES: Taking the determination of mecA gene by polymerized chain reaction (PCR) method as a reference in determining methicillin resistance in Staphylococcus species, we aimed at comparing the reliability levels of disk diffusion, latex agglutination test and chromogenic agar use methods. METHODS: This prospective study was conducted on 228 Staphylococcus strains isolated between January 2020 and December 2020 in Samsun Training and Research Hospital. Disk diffusion, latex agglutination and chromogen agar medium methods were applied along with the polymerized chain reaction (PCR) method. RESULTS: The mecA gene was detected in 47 of the isolates (20.6%) by the PCR method, and these isolates were accepted as methicillin-resistant. When the PCR result was taken as a reference, the sensitivity of the disk diffusion method became 100%, and specificity became 45.9%; sensitivity of latex agglutination was determined as 80.9%, and specificity as 70.2%; sensitivity of chromogenic agar as 85.1% and its specificity was found to be 95%. Only in S. aureus isolates, the highest sensitivity and specificity rate (100% and 88%, respectively) belonged to chromogenic agar. CONCLUSION: Chromogenic agar provides more reliable data for S. aureus isolates, and the combined use of all three methods does not significantly increase reliability.

Efficacy of extracorporeal shock wave therapy for pillar pain after open carpal tunnel release: a double-blind, randomized, sham-controlled study.

BACKGROUND: Pillar pain may develop after carpal tunnel release surgery (CTRS). This prospective double-blinded randomized trial investigated the effectiveness of extracorporeal shock wave therapy (ESWT) in pillar pain relief and hand function improvement. METHODS: The sample consisted of 60 patients with post-CTRS pillar pain, randomized into two groups. The ESWT group (experimental) received three sessions of ESWT, while the control group received three sessions of sham ESWT, one session per week. Participants were evaluated before treatment, and three weeks, three months, and six months after treatment. The pain was assessed using the visual analogue scale (VAS). Hand functions were assessed using the Michigan hand outcomes questionnaire (MHQ). RESULTS: The ESWT group showed significant improvement in VAS and MHQ scores after treatment at all time points compared to the control group (P < 0.001). Before treatment, the ESWT and control groups had a VAS score of 6.8 ± 1.3 and 6.7 ± 1.0, respectively. Three weeks after treatment, they had a VAS score of 2.8 ± 1.1 and 6.1 ± 1.0, respectively. Six months after treatment, the VAS score was reduced to 1.9 ± 0.9 and 5.1 ± 1.0, respectively. The ESWT group had a MHQ score of 54.4 ± 7.7 before treatment and 73.3 ± 6.8 six months after. The control group had a MHQ score of 54.2 ± 7.1 before treatment and 57.8 ± 4.4 six months after. CONCLUSIONS: ESWT is an effective and a safe non-invasive treatment option for pain management and hand functionality in pillar pain.

Can ultrasound-guided infraclavicular block be an alternative option for forearm reduction in the emergency department? A prospective randomized study.

OBJECTIVE: Ultrasound-guided infraclavicular nerve block (IB) has become a well-established method in several outpatient procedures; however, its use in emergency departments (EDs) remains limited. The aim of this study was to compare procedural sedation and anlagesia (PSA) and IB in the pain management for patients who underwent forearm fracture reduction in the ED. METHODS: This prospective randomized study included 60 patients aged 18 to 65 years, who visited the ED with forearm fractures. They were randomly divided into two groups: Group PSA (n=30) and Group IB (n=30). The pain scores of patients were evaluated before and during the procedure with the visual analog scale. Complications and patient and operator satisfaction levels were recorded. RESULTS: There was no difference between the two groups in terms of demographic characteristics. The median (interquartile range) pain scores observed during the procedures were significantly higher in Group PSA than in Group IB (4 [4-6] vs. 2 [0-2], respectively; P<0.001). Patient and operator satisfaction levels were significantly higher in Group IB (P<0.001). Oxygen desaturation was statistically higher in Group PSA than in Group IB (40.00% vs. 3.33%, respectively; P=0.002). CONCLUSION: IB was an effective alternative for reducing pain and increasing patient satisfaction in ED patients undergoing forearm fracture reduction.

Analysis of Clinical Outcomes in Pediatric Distal Tibia Triplanar Fractures Treated Surgically and Conservatively.

Purpose We aimed to analyze the clinical and functional outcomes of patients who underwent surgery or received conservative treatment to look into the impact of treatment methods on clinical outcomes. Methods A retrospective study was performed on 25 patients with a minimum one-year follow-up. Patients were divided into two groups based on joint and physis displacement measured on preop CT images. Patients with a displacement of > 2 mm underwent surgery, while those with a displacement of < 2 mm received conservative treatment. The clinical results were assessed using the Ankle-Hindfoot Scale developed by the American Orthopedic Foot and Ankle Society (AOFAS) and the Modified Weber Protocol (MWP). Results The sample consisted of 14 patients who underwent surgery and 11 patients who received conservative treatment. The surgical group had a mean follow-up of 36.79±14.43 months, while the conservative group had a mean follow-up of 31.82±13.55 months. The surgical and conservative groups had a postop 1st-year AOFAS score of 96.64±3.54 and 93.64 ± 4.69, respectively. The difference was statistically insignificant (p > 0.05), but the surgical group had higher scores numerically. The surgical and conservative groups had a postop 6th-month AOFAS score of 84.64±1.64 and 80.82±2.85, respectively. The difference was statistically significant (p < 0.05). Conclusion The results of both surgical treatment and conservative treatment are satisfactory. Especially, surgical treatment should not be avoided in patients requiring surgery with a displacement of more than 2 mm and surgeons may consider surgery for better clinical outcomes and earlier rehabilitation in the treatment of triplane fractures.

Sedoanalgesia Versus Infraclavicular Block for Closed Reduction of Pediatric Forearm Fracture in Emergency Department: Prospective Randomized Study.

OBJECTIVE: Procedural sedoanalgesia is commonly used in pediatric patients in the emergency department (ED) for interventional procedures, diagnosis, and treatment. However, this method causes serious systemic complications, such as respiratory and cardiac depression. To minimize these complications, ultrasound-guided regional anesthesia methods have been used in recent years. We aimed to compare the use of procedural sedoanalgesia (PSA) and infraclavicular block (ICB) in the pain management of pediatric patients who underwent closed reductions of forearm fractures. MATERIALS AND METHODS: This prospective, randomized, clinical study included patients aged 3 to 15 years who presented to the ED with forearm fractures. The patients were divided into 2 groups: the procedural sedoanalgesia group (group PSA, n = 30) and ultrasound-guided ICB group (group ICB, n = 30). Pain scores of the patients were evaluated using the Wong-Baker FACES Scale before and during the procedure. Pain scores and parental and operator satisfaction were compared between the groups. RESULTS: There was no statistical significance in terms of demographic data. The pain scores observed during the procedures were significantly higher in the group PSA than in the group ICB (3.07 ± 1.55 vs 0.47 ± 0.86, respectively; P < 0.001). The parental and operator satisfaction of the ICB group was significantly higher than that of the PSA group (P < 0.001). CONCLUSIONS: Ultrasound-guided ICB is a safe and effective method in the management of pain during closed reduction of forearm fracture in pediatric patients in EDs. It can be used safely in emergency rooms and has a high level of both parental and operator satisfaction.
