Assessment of Coracoclavicular Ligament Healing on MRI After Arthroscopic TightRope Fixation for Acute Acromioclavicular Joint Dislocation.

Background: Arthroscopic-assisted fixation of acute high-grade acromioclavicular (AC) joint dislocation has gained popularity in the last decade. Coracoclavicular (CC) fixation using the TightRope device is a less invasive technique. Purpose: To investigate CC ligament healing and functional outcomes after arthroscopic fixation using the TightRope device for acute AC joint disruption. Study Design: Case series; Level of evidence, 4. Methods: The study retrospectively analyzed the data of patients admitted for arthroscopic surgical treatment of acute AC joint injury using a single TightRope device. The data collection commenced in October 2021. The Constant-Murley (CM) score and University of California, Los Angeles (UCLA) shoulder score were used for functional evaluation. The CC distance (CCD) was measured on plain radiographs, whereas healing of the CC ligament was evaluated on magnetic resonance imaging (MRI). Statistical analyses were conducted with the Mann-Whitney U test, independent t test, or paired t test, as appropriate. Results: The analysis included 33 patients with a mean age of 37.7 years (range, 24-49 years) and a minimum follow-up of 24 months. Significant preoperative to postoperative increases were noted in both the CM and UCLA scores (from 34.1 ± 7.6 to 93.3 ± 3.6 and from 8.7 ± 2.1 to 32.9 ± 1.7, respectively; P < .0001 for both). The CCD decreased from 21.8 ± 3.02 mm preoperatively to 10.6 ± 1.2 mm postoperatively (P < .0001). All patients displayed CC ligament healing on MRI. Two patients with superficial infection and 1 case of partial reduction loss were confirmed at the end of this study. Conclusion: The arthroscopic TightRope technique was found to be a reliable and less invasive method of fixation for acute AC joint disruptions. The CC ligament healed adequately based on MRI evaluation, and the patients regained their preinjury activities, with favorable functional outcomes and minor comorbidities.

Intramedullary Kirschner wire fixation of displaced distal forearm fractures in children.

AIM OF THE WORK: This study was designed to highlight internal fixation by intramedullary K-wires for displaced distal forearm fractures among children and analyze the results of this technique. We hypothesize that physis-sparing intramedullary fixation prevents displacement with a lower complication rate. METHODS: This prospective case series involving 47 patients was conducted between February 2018 and December 2019. All patients with open physis presented with recent displaced distal forearm fractures were included, and all of them were treated with an intramedullary k-wire fixation for both bones with the assessment of the union rate, union time, suspected complication, radiographic evaluation, and functional outcome. RESULTS: The study population consisted of 31 boys (66%) and 16 girls (34%). The mean age of the patients was 10.68 ± 2.728 years (range, 7-15 years). All fractures were united in a median of 6 weeks (range, 4-8 weeks), The functional outcome after 12 months was normal in 42 patients (89.4%), whereas, in five patients (10.6%), the functional parameters were minimally reduced. The median preoperative angulation improved from 36° (range, 24°-52°) preoperatively to 4° (range, 0°-10°) on immediate postoperative radiographs. After 12 months, the median angulation was 2° (range, 0°-7°) (p < 0.001). The angulation of the distal radius immediately after surgery and at the final follow-up was statistically correlated with the functional outcome (p < 0.001 and 0.002, respectively). CONCLUSION: This technique provides a good result with less susceptibility to re-displacement and low complication rates. LEVEL OF EVIDENCE: Level IV.

Comparative Evaluation of Arthroscopically Assisted Coracoclavicular Fixation Versus Hook Plate Fixation for Unstable Distal Clavicle Fractures: A Minimum 2-Year Follow-up Study.

Background: Neer type 2 distal clavicular fractures are associated with poor outcomes after nonoperative management. Surgical management is preferred, and various fixation methods have been studied. Purpose: To assess the clinical and radiological outcomes in patients with unstable distal-end clavicular fractures that were treated with hook plate (HP) or arthroscopically assisted coracoclavicular (AAC) fixation. Study Design: Cohort study; Level of evidence, 3. Methods: We retrospectively compared the clinical and radiological results of HP versus AAC fixation in patients who had unstable lateral-end clavicular fractures and at least 2 years of follow-up. The recorded postoperative Constant score, American Shoulder and Elbow Surgeons score, and shoulder forward flexion were compared between treatment groups using the independent t test. Fracture union was evaluated on routine shoulder radiographs. Results: This study included 34 patients (17 with HP fixation, 17 with AAC fixation) with a mean ± SD age of 36.4 ± 8.3 years for the HP group and 37.2 ± 6.9 years for the AAC group. The mean follow-up period was 30.8 ± 2.8 months for the HP group and 28.8 ± 3.01 months for the AAC group. No statistically significant difference between groups was observed regarding postoperative Constant score (89.7 vs 92.5; P = .07), American Shoulder and Elbow Surgeons score (88.2 vs 91.1; P = .12), or mean time to union (10.1 vs 9.3 weeks; P = .16). Postoperative shoulder forward flexion was better in the AAC group (168.2° ± 4.3°) versus the HP group (161.9° ± 6.6°; P = .002), and the complication rate was lower in the AAC group (5.8% vs 41.1%; P = .03). Conclusion: Both the AAC and HP fixation methods were effective in the surgical fixation of unstable Neer type 2 lateral-third clavicle fractures, with successful functional and radiological outcomes. However, AAC fixation provided an earlier return to work with fewer complications.

A Single Intramedullary K-Wire Is Sufficient for the Management of Nonthumb Metacarpal Shaft Fractures.

OBJECTIVE: This study aims to evaluate the outcome after the internal fixation of diaphyseal metacarpal fractures by a single intramedullary K-wire. METHODS: In this prospective case series study, conducted from July 2017 to June 2019 in 23 adult patients with a single, unstable, diaphyseal metacarpal fracture, outcomes after internal surgical fixation using a single antegrade intramedullary K-wire were evaluated. The outcomes were evaluated by union rate, time to union, handgrip measurements at 6 and 12 months, and the modified Disabilities of the Arm, Shoulder, and Hand (DASH) score at 12 months. RESULTS: The study population consisted of 17 males and 6 females, with a mean patient age of 28.4 ± 8.5 years (range, 16-45 years). The median time to final follow-up was 14 ± 1.8 months (range: 12-24 months). The mean duration of the union was 7.3 ± 1.6 weeks (range: 5-11 weeks), with a union rate of 95.7% (22 cases). The mean handgrip strength was 68% ± 12.8% of the strength of the uninjured hand after 6 months and 92.7% ± 6.9% after 12 months. The mean modified DASH score was 2.6 ± 0.26 after 12 months (range: 0-5.8). There were no cases of malrotation or infection. In conclusion, using a single 1.8-2.0 mm K-wire gives excellent functional outcomes and union rate without significant complications when used to treat an unstable metacarpal shaft fracture.

Portal vein thrombosis in hepatitis C virus-related cirrhotic patients: Prevalence and clinical characteristics in an Egyptian cohort.

Portal vein thrombosis is a catastrophe not uncommonly complicating hepatitis C virus-related liver cirrhosis. To estimate its prevalence and clinical characteristics, we investigated 1000 cirrhotic patients by abdominal ultrasound or Doppler study at least. Portal vein thrombosis was found in 21.6%, of whom 157 (72.7%) had malignancy. Complete portal vein thrombosis was found in 70.4%. Half of all these patients had at least one episode of portal hypertensive bleeding, a third had abdominal pain and a quarter presented with jaundice. Portal bilopathy was diagnosed in two cases (0.9%). There was significant association between severity of liver disease, ascites, male gender and site of segmental focal lesion and portal vein thrombosis.
