Progressive Loss of Acromioclavicular Joint Reduction Correlated with Progressive Clavicular Tunnel Widening after Coracoclavicular Stabilization in Acute High-Grade Acromioclavicular Joint Injury.

Objectives: This study aimed to compare 24-month radiographic follow-ups of clavicular tunnel widenings (CTWs) and coracoclavicular distances (CCDs) and examine correlations between these measurements in patients following combined coracoclavicular stabilization and acromioclavicular capsule repair in treatment of acute high-grade acromioclavicular joint injury. Methods: This retrospective study reviewed the records of patients with acute Rockwood type V acromioclavicular joint injury who underwent surgery within 3 weeks after their injury. All patients had follow-ups at 3 and 6 months and 1 and 2 years. The CTWs were measured on anteroposterior radiographs between the medial and lateral borders at the superior, middle and inferior levels of the tunnels. On anteroposterior radiographs of both clavicles, the CCDs were measured at the shortest distance between the upper border of the coracoid process and the inferior border of the clavicle and reported as the CCD ratio, which was defined as the ratio of the affected and unaffected clavicles. At the final follow-ups, clinical outcomes were assessed using American Shoulder and Elbow Surgeons (ASES) scores. Results: This study included seventeen men and six women with a mean age of 47.26 ± 10.68 years. At the final follow-ups, the mean ASES score of all patients was 95.28 ± 3.62. We found a significant correlation between the increase in the CTWs and the increase in the CCD ratios (Spearman's rho correlation coefficient range 0.578-0.647, all p-values < 0.001). Conclusions: We found long-term postoperative widening of the clavicular tunnels, which correlated positively with a gradual postoperative decline in the acromioclavicular joint alignment reductions.

Using a Nice knot to simplify and strengthen closed reduction in displaced distal clavicle fracture: a technical note.

A displaced distal clavicle fracture often necessitates surgical intervention, with various open and closed reduction options. Open reduction is easier but raises blood supply concerns, while closed reduction can involve complex deforming forces with differing displacement vectors. Herein, we demonstrate how a Nice knot with its sliding and self-locking qualities can be used to make closed reduction easier and the alignment more secure. A case report illustrates this Nice knot application in a 61-year-old male with a distal clavicle fracture. The Nice knot's ability to be loosened and retightened ensured more precise alignment in this case. The Nice knot technique is a versatile option for easier and more secure distal clavicle fracture management.

Looping a suture under the coracoid process using a modified pelvic suture needle in coracoclavicular stabilization.

A distal clavicle fracture is a common shoulder injury. Coracoclavicular (CC) stabilization is a popular procedure for treating this injury. However, with this method, there is a technical difficulty in looping the suture under the coracoid base with instruments normally available in the operating room (OR). Herein, the authors describe modifying a pelvic suture needle to ease this process. Case presentation: An 18-year-old Thai female presented with left shoulder pain after a fall while cycling. The physical examination showed tenderness at the prominent distal clavicle. The radiograph of both clavicles showed a displaced distal clavicle fracture of the left shoulder. After discussing the treatment, she decided to have CC stabilization as the authors recommended. Clinical discussion: CC stabilization is one of the main surgical techniques used in treating an acute displaced distal clavicle fracture. The most important but difficult step of the CC stabilization is passing a suture under the coracoid base. To make this step easier, various commercial tools have been created, however, they are expensive ($1400-1500 per piece), and most operating rooms in resource-limited countries do not have them available. The authors modified a pelvic suture needle specifically for use in looping a suture under the coracoid process, which is hard to do with standard surgical tools.

Using a right-angle forceps clamp to pass a suture under the coracoid base in coracoclavicular stabilization: a technical note.

A distal clavicle fracture is a common injury of the shoulder joint. Coracoclavicular (CC) stabilization is one of the recommended procedures for treating the distal clavicle fracture. However, it is difficult to pass the suture under the coracoid process with instruments normally available in the operating room (OR). Herein, the authors describe a simple technique to accomplish this suture passing quickly and easily using tools available in the OR. Case presentation: A 59-year-old Thai female presented with right shoulder pain after a fall. The physical examination showed a prominent bulge and tenderness at the right distal clavicle. A radiograph of both clavicles showed a right displaced distal clavicle fracture. After discussing the possible treatments with her, she decided to have CC stabilization as we recommended. Clinical discussion: In CC stabilization, the most important but difficult step is passing a suture under the coracoid base. There are some specialized commercial instruments which are matched to the shape of the coracoid process to make it easy to perform this step, but all are highly expensive (~$1400-1500 per piece) and thus often not available in ORs in resource-limited settings. Conclusion: The authors devised a technique using standard surgical instruments and materials available in all ORs to enable them to pass a suture easily and quickly under the coracoid base.

Displaced varus proximal humerus fracture with conservative treatment: a case report.

The authors report a case of an elderly female with a displaced varus misalignment of a proximal humerus fracture which met the indications for surgery, but the patient was treated conservatively with an arm sling due to the wishes of the patient and her relatives. The clinical outcome was nearly full function compared with the right shoulder. Presentation of case: A 65-year-old Thai female presented with right shoulder pain 1 h after a fall during which her right shoulder hit the floor. Radiographs of the right shoulder in anteroposterior and lateral transcapular views showed a proximal humerus fracture with varus misalignment. The patient and her relatives decided on conservative treatment with an arm sling. At 12 weeks following the fall she was able to move her right shoulder nearly equally to the left shoulder. Intervention and outcome: The authors discussed the treatment options with the patient and her relatives and recommended open reduction and internal fixation with a locking plate and screw, but they decided on conservative treatment with an arm sling. At 12 weeks following the fall she was able to move her right shoulder nearly equally to the left shoulder. She had no pain and could do normal life activities with the right shoulder. Relevance and impact: Patients with severe varus deformity are usually treated with surgery. If there are contraindications for surgery, the stability of the fracture should first be evaluated through radiographs of the fracture in various arm positions.

Using a modified recycled corkscrew suture anchor to pass a suture under the coracoid base.

INTRODUCTION: A common shoulder injury is a distal clavicle fracture which can be treated with various methods such as coracoclavicular (CC) stabilization, fixation with a distal clavicular locking plate, hook plate or tension band wiring. In CC stabilization, the most difficult step is passing a suture under the coracoid base because there is no standard instrument matched to the shape of the coracoid process. We propose a technique using a modified recycled corkscrew suture anchor to pass a suture under the coracoid base. CASE PRESENTATION: A 30-year-old Thai female with a left clavicle fracture was scheduled for CC stabilization. In the step of passing a suture under the coracoid base, we used a modified recycled corkscrew suture anchor to quickly and easily perform this step. CLINICAL DISCUSSION: There are some specialized commercial tools which are designed to pass a suture under the coracoid base but all are very expensive (∼ $1400-1500 per piece). To overcome this problem, we modified a used sterilized corkscrew suture anchor to pass a suture under the coracoid base, normally done from the medial to lateral sides, recycling a device usually discarded after use.

A simple way to deal with an inadvertently cut suture while inserting the screw in the tibial tunnel during ACL reconstruction.

INTRODUCTION: There are many complications that can occur during or after ACL reconstruction, including a suture inadvertently cut by the screw threads while inserting the interference screw in the tibial tunnel. No fixes for this small but annoying problem have been proposed to date in the literature, and herein we propose a simple way to deal with this situation by bringing the tibial side of the ACL graft through the anterolateral portal and re-suturing with a stronger suture material. CASE PRESENTATION: A 48-year-old Thai female was undergoing an ACL reconstruction with a hamstring graft following a standard technique when the holding suture and distal part of the ACL graft were accidentally cut by the screw. Rather than redoing the graft from the beginning, we did a workaround by bringing the tibial end of the graft through the AL portal and re-suturing. DISCUSSION: In ACL graft fixation, when inserting the interference screw into the tibial tunnel there is a risk of cutting the holding suture with the screw. When this happened in our situation, we decided to attempt to redo the suture by first taking the graft out through the AL portal and then re-suturing with a stronger suture material. CONCLUSION: If inadvertently cutting the holding suture while inserting the screw in the tibial tunnel during ACL reconstruction occurs, the surgeon can use the simple solution we applied in this case to solve this problem or to avoid having to redo the entire procedure.

Shoulder Injury Related to COVID-19 Vaccine Administration: A Case Series.

BACKGROUND: A shoulder injury related to vaccine administration (SIRVA) is a vaccination complication that can affect daily life activities. To date, there have been no case series of patients diagnosed as SIRVA following a COVID-19 vaccination. We offer a series of seven SIRVA cases including clinical presentations, investigations and treatment outcomes. METHODS: A retrospective chart review was performed for seven patients who developed SIRVA following a COVID-19 vaccination between April 2021 and October 2021. All patients had no prior shoulder pain before their vaccination and then developed shoulder pain within a few days following the vaccination, which did not spontaneously improve within 1 week. RESULTS: Four of the seven patients were male, and the average age was 62.29 ± 7.76 years. The average body mass index was 25.1 ± 2.2 kg/m2. In all cases, the cause of the SIRVA was from an incorrect COVID-19 vaccine administration technique. Two patients developed shoulder pain immediately following the injection, one patient about 3 h after the injection, and the other four patients within the next few days. Two of the seven patients visited the orthopedic clinic after the persistent shoulder pain for 3 and 4 days and the other five patients 1-9 weeks following their injections. One of the seven patients was treated with combined intravenous antibiotic and oral non-steroidal anti-inflammatory drug (NSAID) because septic arthritis of the shoulder could not initially be ruled out, and recovered within 2 weeks. The other six patients had shoulder pain without acute fever, and five of them were treated with only oral prednisolone 30 mg/day for 5-10 days, following which the pain improved and they all could return to normal activities within 14 days, with no side effects from the prednisolone such as stomachache, nausea, vomiting, headache, or dizziness. DISCUSSION AND CONCLUSION: In our series, the most common cause of SIRVA was an incorrect vaccination technique. Most patients responded well to oral NSAIDs or oral prednisolone. CLINICAL RELEVANCE: All SIRVAs were from an incorrect injection technique and not actually the vaccination, so our series highlights the importance of ensuring all vaccinators understand the importance of taking proper care with the injection technique. Additionally, most of our patients with SIRVA from a COVID-19 injection responded well to oral prednisolone (30 mg/day). If there are no contraindications, we suggest this as the first line treatment for COVID-19-related SIRVA.

Using a modified J-shaped Y-knot all-suture anchor to pass a suture under the coracoid process in coracoclavicular stabilization.

INTRODUCTION: The distal clavicle fracture is a common shoulder injury. There are several treatment methods which can achieve good outcomes, of which coracoclavicular (CC) stabilization is one of the most popular surgical options. In CC stabilization, the step of passing a suture under the coracoid base is the most difficult step because the standard surgical tool is not designed for passing a suture under the coracoid process. To solve this problem, there are commercial tools for use in this step but all of them are expensive, and thus of limited availability in developing or low-resource settings. We propose a modified J-shaped Y-knot all-suture anchor for use in passing a suture under the coracoid process. CASE PRESENTATION: A 45-year-old Thai male who had a left distal clavicle fracture was scheduled for CC stabilization. We modified a sterile Y-knot all-suture anchor to loop underneath the coracoid base which was easy to use and can design individually. DISCUSSION: In CC stabilization, there are many specialized commercial tools specially designed to easily pass the suture under the coracoid base but they are very expensive. The surgeon can use this technique to modify J-shaped Y-knot all-suture anchor for use in CC stabilization, recycling a Y-knot all-suture anchor normally discarded after use. CONCLUSION: A modified J-shaped Y-knot all-suture anchor can use in passing a suture under the coracoid process.

Using a Modified Kirschner Wire to Pass the First Suture Under the Coracoid Base in Coracoclavicular Stabilization.

The acromioclavicular (AC) joint injury is a common shoulder injury in sports medicine. Combined coracoclavicular stabilization with AC capsule repair is 1 of 2 preferred treatments in acute high-grade AC joint injury. In East-Asian populations, the surgeon prefers to pass the first suture under the coracoid base, which is difficult using only basic surgical tools. We propose using a modified K-wire to pass the first suture under the coracoid base.

Simulated weightbearing computed tomography for verification of radiographic staging of varus ankle osteoarthritis: a cross-sectional study.

BACKGROUND: Varus ankle osteoarthritis is classified using only weightbearing anteroposterior ankle radiographs; however, sagittal ankle alignment may also affect the position and extent of joint space obliteration. We hypothesized that the sagittal alignment of the ankle may also affect the position and extent of joint space obliteration visible on the coronal section; therefore, we identified the sites of joint space obliteration in patients with stage 3 varus ankle osteoarthritis for comparison with the sites observed on simulated weightbearing computed tomography and investigated the effects of anterior and posterior ankle subluxation. METHODS: Simulated weightbearing computed tomography scans of 83 ft with varus ankle osteoarthritis (26 stage 3a, 57 stage 3b) were performed to check for joint space obliteration in the ankle. Further classification as exhibiting either anterior, posterior, or no subluxation on weightbearing lateral radiographs was performed. RESULTS: Anterior, posterior, and no subluxation was seen in 5, 9, and 12 ankles among the 26 classified as stage 3a, respectively, and in 22, 12, and 23 ankles among the 57 classified as stage 3b, respectively. The mean tibial lateral surface angle on weightbearing lateral radiographs in stage 3a ankles was 75.6, 83.3, and 80.3 degrees in the anterior, posterior, and no subluxation groups, respectively; and 75.5, 86.6, and 82.7 degrees in stage 3b ankles (p < .05). In stage 3b ankles, widespread joint space obliteration was observed at the anterior distal articular surface of the tibia in all 22 ankles with anterior subluxation and at the posterior distal articular surface of the tibia in all 12 ankles with posterior subluxation. CONCLUSIONS: Simulated weightbearing computed tomography revealed joint space obliteration at the anterior distal articular surface of the tibia in stage 3b ankles with anterior subluxation and at the posterior side in stage 3a and 3b ankles with posterior subluxation. In some patients with stage 3 varus ankle osteoarthritis, the obliteration of the joint space is difficult to evaluate accurately using only weightbearing anteroposterior radiographs; weightbearing lateral radiographs should also be performed.

Shoulder injury related to Sinovac COVID-19 vaccine: A case report.

INTRODUCTION: After a vaccination, patients frequently have clinical symptoms of pain and swelling over the injection area which usually resolve 2-3 days after the injection. If the symptoms do not improve, a shoulder injury related to vaccine administration (SIRVA) will be considered, perhaps related to an improper injection technique. Herein we report our first case of a SIRVA after a Sinovac COVID-19 vaccination which occurred due to deep penetration and direction of the needle. The clinical symptoms of the patient improved after treatment with combined oral non-steroidal anti-inflammatory drugs and a short course of intravenous antibiotic. CASE PRESENTATION: A 52-year-old Thai male without prior shoulder pain had a Sinovac COVID-19 vaccination at his right shoulder. The injection was given by a nurse using a 27-gauge needle, 1.5 inches in length. The injection landmark was 3 finger breadths below the midlateral edge of the acromial process. The direction of the needle was 45° to the skin cephalad. Three days after receiving the vaccine the patient began to have right shoulder pain with limited range of motion and acute fever. He was admitted for medical treatment which his clinical symptoms gradually improved. CONCLUSION: We report a case of subacromial-subcoracoid-subdeltoid bursitis following a Sinovac COVID-19 vaccine injection. This condition is rare, and usually related to an incorrect vaccination technique. To avoid this complication, nurses should identify the correct landmark, use an appropriate needle length, and point the needle in the correct direction.

Suturing the Anterior Cruciate Ligament Using a No. 16 Intravenous Catheter Needle in Avulsion Anterior Cruciate Ligament Injury.

Avulsion anterior cruciate ligament injuries are more common in pediatric patients. There are several methods of fixation available for these injuries (tibial intercondylar eminence fractures), such as the pullout suture technique, screw fixation, and suture anchor fixation. Currently, a pullout technique is widely used for fixation. We purpose a pullout technique method using a modified No. 16 intravenous catheter needle to suture the anterior cruciate ligament fiber instead of a suture hook or suture passer. We also use one anterior tibial tunnel for this arthroscopic pullout fixation technique to decrease the incidence of physeal injury in pediatric patients by using many tibial tunnels.

Patient Position Is Related to the Risk of Neurovascular Injury in Clavicular Plating: A Cadaveric Study.

BACKGROUND: Fixation of clavicle shaft fractures with a plate and screws can endanger the neurovascular structures if proper care is not taken. Although prior studies have looked at the risk of clavicular plates and screws (for example, length and positions) to vulnerable neurovascular structures (such as the subclavian vein, subclavian artery, and brachial plexus) in the supine position, no studies to our knowledge have compared these distances in the beach chair position. QUESTIONS/PURPOSES: (1) In superior and anteroinferior plating of midclavicle fractures, which screw tips in a typical clavicular plating approach place the neurovascular structures at risk of injury? (2) How does patient positioning (supine or beach chair) affect the distance between the screws and the neurovascular structures? METHODS: The clavicles of 15 fresh-frozen cadavers were dissected. A hypothetical fracture line was marked at the midpoint of each clavicle. A precontoured six-hole 3.5-mm reconstruction locking compression plate was applied to the superior surface of the clavicle by using the fracture line to position the center of the plate. The direction of the drill bits and screws through screw holes that offer the greater risk of injury to the neurovascular structures were identified, and were defined as the risky screw holes, and the distances from the screw tips to the neurovascular structures were measured according to a standard protocol with a Vernier caliper in both supine and beach chair positions. Anteroinferior plating was also assessed following the same steps. The different distances from the screw tips to the neurovascular structures in the supine position were compared with the distances in the beach chair position using an unpaired t-test. RESULTS: The risky screw holes were the first medial and second medial screw holes. The relative distance ratios compared with the entire clavicular length for the distances from the sternoclavicular joint to the first medial and second medial screw holes were 0.46 and 0.36 in superior plating and 0.47 and 0.37 in anteroinferior plating, respectively. The riskiest screw hole for both superior and anteroinferior plates was the second medial screw hole in both the supine and beach chair positions (supine superior plating: 8.2 mm ± 3.1 mm [minimum: 1.1 mm]; beach chair anteroinferior plating: 7.6 mm ± 4.2 mm [minimum: 1.1 mm]). Patient positioning affected the distances between the riskiest screw tip and the nearest neurovascular structures, whereas in superior plating, changing from the supine position to the beach chair position increased this distance by 1.4 mm (95% CI -2.8 to -0.1; supine 8.2 ± 3.1 mm, beach chair 9.6 ± 2.1 mm; p = 0.037); by contrast, in anteroinferior plating, changing from the beach chair position to the supine position increased this distance by 5.4 mm (95% CI 3.6 to 7.4; beach chair 7.6 ± 4.2 mm, supine 13.0 ± 3.2 mm; p < 0.001). CONCLUSIONS: The second medial screw hole places the neurovascular structures at the most risk, particularly with superior plating in the supine position and anteroinferior plating in the beach chair position. CLINICAL RELEVANCE: The surgeon should be careful while making the first medial and second medial screw holes. Superior plating is safer to perform in the beach chair position, while anteroinferior plating is more safely performed in the supine position.
