Technique of Forearm Fasciotomy

– see forearm compartment syndrome; – Discussion:     – see forearm flexors     – in forearm, both volar & dorsal compartments must be relieved by two incisions placed at 180 deg to each other;          – release of volar compartment may quell elevated dorsal compartment;     – on volar surface, lacertus fibrosis (proximally) & … Read more

Technique for Acetabular Cup Removal

        – Discussion:     – considerations:            – removal of press fit components can often be complicated by heavy bone ingrowth, insertion of under-reamed                   components, or insertion of oversized peripherally oversized cups;     – acetabular exposure:   … Read more

Technique for King-Moe Type III Scoliosis

– See:  – OCS Application and Correction  – Notes for Wrightlock Spinal Fixation System: Technique Overview: The typical hook placement for a Type III scoliotic curve of about 65 degrees (Figure 1) is derived from that recommended by Harrington. Normally, a six hook construct is used. Couplers are placed between the upper and middle sets … Read more

Technique of Blade Plate Insertion

– Discussion:  – 1st guide wire marks femoral anteversion;  – 2nd guide wire marks direction of seating chisel and should be driven into the femoral neck parallel to 1st guide wire;  – note that because the greater trochanter lies slightly posterior to the femoral neck, the guide wire needs to be placed slightly anterior to … Read more

Tarsal Coaliltion

– See: – Talocalcaneal Coalition – Calcaneonavicular Coalition – Discussion: – coalition between tarsal bones is frequent cause of painful flatfoot (pes planus) in the older child or adolescent; – tarsal coalition may be osseous, cartilaginous, or fibrous. – calcaneonavicular coalition bar is most common, followed by middle facet of talocalcaneal coalition joint; – single … Read more

(see also: Accessory Navicular; Kohler’s Disease I) Anatomy navicular joins in front w/ medial, intermediate, & lateral cuneiform bones, which articulate anteriorly w/ first, second, and third metatarsals; navicular provides insertion for tibialis posterior; blood supply to the navicular bone is radial and extraarticular & is subject to loss both at time of injury & … Read more

Tarsal Tunnel Syndrome

– Tarsal Tunnel Syndrome: – compression syndrome of the tibial nerve in the tarsal tunnel; – tarsal tunnel is formed by the flexor retinaculum behind and distal to the medial malleolus; – inciting causes: – lipoma, ganglia, or neoplasms within the tarsal tunnel; – an accessory flexor digitorum longus muscle is a common cause; – … Read more

Talar Tilt

– See:    – Talar Tilt: Physical Exam – Tilt Measurement:     – Mortise view:           – line drawn parallel to articular surface of distal tibia;           – second line drawn parallel to talar surface should be parallel to each other;     – alternative method: … Read more
