Background: In some short malunion cases, midshaft clavicular fractures are reported to result in unsatisfactory clinical outcomes. Shortening deformity of the clavicle could change the anatomical alignment of the shoulder girdle and is surmised to affect shoulder kinematics on arm movements. Nevertheless, no report has ever referred to documented changes.
Hypothesis: Scapular motion will change with clavicular shortening in cadaveric models.
Study Design: Controlled laboratory study.
Methods: Twelve cadaveric shoulders were used, and sequential clavicular shortening by 0%, 5%, 10%, 15%, and 20% from the original length was simulated in this study. The scapulothoracic motion during passive arm elevation in 3 planes was monitored using an electromagnetic tracking device. Differences in kinematics of the scapula between the 0% shortening models and the other 4 experimental groups were analyzed.
Results: During arm elevation, posterior tilting and external rotation of the scapula significantly decreased with > or = 10% shortening of the clavicle. Decreased posterior tilting was found with a shorter clavicle and at higher positions of arm elevation in all planes and became obvious during coronal plane elevation. Upward rotation of the scapula did not change with shortening at any elevated arm positions.
Conclusion: The findings of this study clearly indicated that shortening of the clavicle affects the kinematics in the shoulder girdle.
Clinical Relevance: The results of this cadaveric study suggest that clavicular shortening of > or = 10% affects scapular kinematics and might produce clinical symptoms.

Objective: To explore the anatomic characteristics of C7 nerve localization, course, and length during cross-transfer surgery of the C7 nerve through the anterior vertebral approach and investigate the feasibility, safety, and clinical efficacy of C7 nerve transfer surgery through the anterior vertebral approach for the treatment of central upper limb spastic paralysis.
Methods: Four fresh-frozen adult head and neck samples were selected. C7 nerve transfer surgery was simulated through the anterior vertebral approach.

Article Synopsis
- The study investigated the effectiveness of Nice knot-assisted fixation in treating comminuted and displaced clavicle fractures compared to traditional surgical methods.
- A systematic literature search identified 11 relevant studies with a total of 754 patients, analyzing outcomes such as healing time, blood loss, and functional scores.
- Results indicated that Nice knot-assisted fixation led to shorter operative times, less blood loss, faster fracture healing, and improved functional outcomes, though it did not significantly affect hospitalization duration or complications compared to traditional methods.

Article Synopsis
- Most kids with broken collarbones can heal without surgery, but doctors needed to know how long it usually takes for them to heal.
- The study looked at 390 kids with collarbone fractures and found out how healing time varies by age: infants heal in about 4 weeks, school-aged kids in about 8 weeks, and teenagers in about 12 weeks.
- The results help doctors know when to check for healing, so they can ensure kids are recovering on track.
Operative treatment of clavicle fractures results in more opioids prescribed as compared to non-operative management.

Article Synopsis
- * Data was collected from 158 patients treated at a trauma center between 2012 and 2016, comparing demographics, fracture details, and narcotic prescriptions for those who underwent surgery versus those who did not.
- * Findings reveal that patients who received surgical treatment were prescribed significantly more opioids than those treated non-operatively, suggesting that while surgery may have benefits, it also leads to higher opioid consumption.
