Laterally, the peroneal tubercle provides a groove for the peroneal tendons (the brevis superiorly and the longus inferiorly). Most common fx pattern Deforming forces: 6) pectoralis pulls shaft anterior and medial 7) head and attached tuberosities stay neutralNonoperative Closed reduction often possible Sling Operative indications controversial technique - CRPP - Plate fixation - IM device Often missed Deforming forces: GT pulled superior and posterio r by SS, IS, and TM Can only accept minimal displacement ( 5mm) or else it will block ER and ABDNonoperative indicated for GT displaced 5 mm Operative indicated for GT displacement 5 mm - isolated screw fixation only in young with good bone stock - nonabsorbable suture technique for osteoporotic bone (avoid hardware due to impingement) - tension band wiring Nonoperative Minimally or non-displaced Operative ORIF if large fragment excision with RCR if small Thank you for taking the time to provide feedback. The AC joint forms where the clavicle (collarbone) meets the shoulder blade (acromion). The fractures represent high energy injury in young patients whereas are a low energy injuries in old people. It involves separation of the AC joint and injury to the ligaments that support the joint.

The anatomical axis of the knee joint does not coincide with the weight-bearing axis which crosses the center of the femoral head and the center of the knee. Posterior facet is a major weightbearing surface, though the anterior and middle facets bear more weight per unit area. It will be used to make improvements to this website. Internally, the os calcis contains compression and tensile trabeculae. Patients present with pain, deformity, weakness, and inability to use the leg.

Open reduction and internal fixation with restricted weight bearing for 7 weeksOpen reduction and internal fixation with restricted weight bearing for 6 weeksOpen reduction and internal fixation with restricted weight bearing for 67 weeks The anatomical axis is in valgus and subtends an angle of 86 with the knee joint. In a Type 7 injury, the AC ligament tears and the coracoclavicular (CC) ligament sprains or tears slightly causing misalignment in the collarbone. As the axial load is applied to the hindfoot, the talus is driven into the angle of Gissane, dividing the os calcis into two fragments. Young patients often sustain high energy trauma and elderly patients usually have a history of a fall.

Patient needs to evaluated for skin integrity, vascular status in the affected limb. Extra-articular injuries are more likely to occur with a sudden twisting force applied to the hindfoot than with other mechanismsFollowing axial loading, there may also be a rotational element, especially in varus.

Technique guide are not considered high yield topics for orthopaedic standardized exams including the ABOS, EBOT and RC. This form uses a CAPTCHA to ensure that it is submitted by a person, instead of a machine or automated software. The central portion of the middle third is fairly weak cancellous bone, especially weak in compression. A shoulder separation commonly occurs in athletic young patients and results from a fall directly onto the point of the shoulderA Type 6 shoulder separation occurs when there is an AC ligament sprain that does not displace the collarbone. Acromioclavicular joint (AC joint) dislocation or shoulder separation is one of the most common injuries of the upper arm. Full trauma evaluation is warranted if the injury is due to a high energy mechanism.
