Cardiopulmonary Resuscitation II: ACLS Airway Management01:22

Cardiopulmonary Resuscitation II: ACLS Airway Management

19
Airway management is a key skill in emergency and critical care settings, as maintaining a clear airway is essential for adequate oxygenation and ventilation.Head Tilt-Chin Lift TechniqueThe head tilt-chin lift maneuver is an essential technique primarily used in patients without suspected cervical spine injuries. To perform this maneuver, one hand is placed on the patient’s forehead, and gentle pressure is applied backward to tilt the head. The fingertips of the other hand are positioned...

Muscles of the Shoulder01:23

Muscles of the Shoulder

3.9K
The muscles surrounding the shoulder girdle, including the clavicle and scapula, primarily stabilize the scapula. This stable base allows other muscles to move the humerus effectively. Scapular movements often mirror those of the humerus and extend its range of motion. For instance, raising the arm above the head would not be feasible without simultaneous upward rotation of the scapula.

Ankle Joint01:10

Ankle Joint

1.6K
The ankle is formed by the talocrural joint (crural = leg). It consists of the articulations between the talus bone of the foot and the distal ends of the tibia and fibula of the leg. The superior aspect of the talus bone is square-shaped and has three areas of articulation. The top of the talus articulates with the inferior tibia. This is the portion of the ankle joint that carries the body weight between the leg and foot. The sides of the talus are firmly held in position by the articulations...

Self-Locking Screw01:16

Self-Locking Screw

1.6K
A square-threaded screw jack is a mechanical device widely used for lifting heavy loads or applying considerable force. One of the key features that can make a screw jack more effective and reliable is its self-locking capability.
A square-threaded screw jack carrying a load is considered self-locking if the screw retains its position even after the moment applied to it is removed.

Muscles of the Anterior Neck01:26

Muscles of the Anterior Neck

1.8K
The anterior neck muscles are the group of muscles covering the front part of the neck. These muscles are classified into three subgroups. The first one is the superficial muscles, the most visible muscles in the front of the neck. It includes the platysma and sternocleidomastoid. The second group is the suprahyoid muscles, located above the hyoid bone. This group comprises the digastric, mylohyoid, geniohyoid, and stylohyoid. Lastly, the infrahyoid muscles are found below the hyoid bone and...

Summary
This summary is machine-generated.

The Lockdown™ technique shows excellent patient satisfaction for acromioclavicular (AC) joint injuries, with 95.2% reporting good or excellent outcomes. Common complications include prominent hardware and stiffness, but radiological resubluxation doesn't impact patient satisfaction.

Area of Science:

  • Orthopedic Surgery
  • Sports Medicine
  • Traumatology

Background:

  • Acromioclavicular (AC) joint disruption is a frequent injury with varied surgical treatments.
  • Procedures like Lockdown™, Modified Weaver-Dunn, Arthroscopic stabilization, and LARS have varying outcomes.

Purpose of the Study:

  • To evaluate functional and radiological outcomes of AC joint reconstruction using the Lockdown™ technique.
  • Analysis covers a 10-year period at Medway Maritime Hospital.

Main Methods:

  • Retrospective review of 53 patients undergoing AC joint reconstruction (2012-2021).
  • Data collected via electronic records and telephonic interviews (Oxford Shoulder Score, QuickDASH).
  • Radiological assessment of AC joint reduction using hospital PACS data.

Main Results:

  • 42 patients analyzed (92.9% male, mean age 42.2 years, mean follow-up 68 months).
  • Majority had Rockwood type V injuries (71.43%).
  • Significant improvement in Oxford Shoulder Score (21.3 to 44.3) and QuickDASH (50.6 to 9.1).
  • 81% showed radiological reduction; resubluxation occurred in 19% but rarely impacted satisfaction.
  • 95.2% reported excellent or good outcomes.

Conclusions:

  • The Lockdown™ technique provides excellent or good patient satisfaction in over 95% of cases with long-term follow-up.
  • Prominent metalwork and stiffness are the most frequent clinical complications.
  • Radiological resubluxation is observed in approximately 20% of cases but does not correlate with patient dissatisfaction.
