- Sugar Tong Splint: elbow bent to 90 deg, 4 inch width length from 3-4 finger from axillary fossa under the arm to come over the acromion process
Orthopedic Bracing:
Purpose:
- Prophylactic- protect a joint and surrounding soft tissue (ankle brace instead of tapping)
- Functional- provide support & protection to existing injury or post surgery (ACl)
- Rehabilitative- used for post surgery to immobilize, some allow you to control ROM through adjustable hinges (Elbow brace to allow certain flexion and extension ROM)
Objectives:
- Support and protect when preventing injury, treating and rehabilitating existing injury
- Compression to reduce effusion and swelling
- Control ROM during rehabilitation
Brace Migration:
- To reduce migration
- Take brace on and off and reapply step by step
- Use of neoprene sleeve under
- Tape adherent spray
Types:
- Spider pad: shock absorber, volleyball knee pad
- Neoprene Sleeve: warmth and compression, thigh compression
- Shin splint calf sleeve: pressure on the medial tibia
- Patellar Femoral Strap: pressure on patellar tendon, ChoPat, patellar tendon strap
- Patellar Femoral Stress Syndrome Brace: Donought, lateral J on lat side of patella, H brace, true pull- lat hinge
- OA brace- osteoarthritis brace, relieves friction of bone on bone
- AS0: ankle stabilizing orthotic
- Air Heel: recommended for treatment of plantar fascitiis, air pocket over the Achilles tendon
- Playmaker: ROM brace, can control ROM, mcl, acl, meniscus
- DonJoy: derotational brace, to measure 6 inches above the patella
- Custom Fit: hollow carbon fiber, can break lifetime warranty, hinge absorbs shock
Orthotics:
- Therapeutic device placed in the show to Dec stress to the foot and LKC??
- Brings the foot to the ground
- Indications: imbalances in the foot, shock absorption, pressure sensitive areas, reduce shearing forces, special conditions
- Pes Cavus- High Medial Long Arch (tibia externally rotates), Pes Planus- Flat Feet
- Running shock= 2 to 3x body weight
- Cavus Foot- Excessive Supination
- Soft orthotic to inc shock absorption
- Pronate the talus, tibia internally rotates (knock kneed)
- Turf Toe- want forefoot ridgity
Parts:
- Shell: primary material (ridged, semiridgid, soft)
- Post: brings floor to foot, used to control the abnormal mvmt, rear foot controls calcaneus, forefoot controls subtalar and metatarsal mvmt
- Arch pad- flat foot, cavus foot
- Metatarsal pad- plantar callosities, forefoot pain
- Rear foot post- heel varus and valgus
- Forefoot post- forefoot varus and valgus
- Forefoot extension- covers the entire plantar surface of foot, most athletic ones are only 3/4ths the length (calcaneus to metarsal heads)
- Cover- shock absorption, attractiveness and durability
Types:
- Ridged: usually sent out, nonflexible acrylics, slipper made with the casting stuff
- Semirigid: majority, made from low temp thermoplastics, cork, foam, and leather, used with extrinsic post, combine support and shock absorption, easy to modify, medial and lateral flares prevent slippage, can be used as temporary for trials, or they can end up keeping them
- Soft: Shock absorption, relief of pressure areas and relief from shearing forces
- Turf Toe- excessive hyperextension of the 1st MTP joint—half steel plate—full length orthotic
- Sesamoiditis- j pad- down 2 MT and hooks proximal to sesamoids
- Metatarsalgia- Pain in the forefoot, metatarsal pad, placed proximal to MT heads, can also be used to treat interdigital neromas, ---tear drop pad- spread the transverse arch- spreads the metatrsal heads increasing the distance btw them
- Morton Neuroma- occurs at 3-4th digit, nerves get impinged, poke on it to re-create symptoms
- Plantar Fasciitis- control rear foot mvmt, semiridgid orthotic, deep heel cup—night splint

Joint Reduction:
- Shoulder Reduction: Kocher Technique- reduction of an anterior dislocation, you can also use the Stimson technique, this is with the pt laying down and holding a wt
- Finger Reduction: distract, place a towel over joint, send for x rays, rot fx can require surgery
- Anterior Instability- in men in early 20s, “dead arm”
- Posterior Instability- seizure or severe electric shock, repetitive subluxation, post shoulder pain
- Multidirectional Instability- in athletes with congenital hyperlaxity of multiple joints in sports requiring overhead arm motions, vague symptoms with activity
- Posterior shoulder reduction- place in sling or 4s spica method, ice bag, x-ray-fx and lesions
- Patellar reduction- laterally dislocated, move knee into extension while applying an anteriomedial force to lift the patella over the femoral condyle and back into the groove.
- For patellar dislocations be aware of distal pulse, due to the genicular arteries that wrap around the knee
Colle’s Fx:
- Fx of the distal radius—silver fork sign—dorsal displacement of distal fragment and volar angulation
- Ulnar styloid fracture can occur
- X ray views- AP and Lateral
- Zero Variance- normal
- + Variance- ulna is higher than radius (problem with supination and pronation)—LAC to limit the amount of supination and pronation
- - Variance- ulna is sitting below the radius
Casting with Colle’s Fx:
- nondisplaced- SAC- 4-6wks unreduced, 6-8wks reduced
- Intrarticular Fx- LAC with thumb spica 3-6wks( SAC
- Elderly Pt’s always in a SAC because if not they will never regain full extension
- External Fixator- comminuted, displaced, or open fx—6wks
- Open Reduction Internal Fixation- Intraarticular fx- post op cast 2-6 wks
- Nerve block- injection that blocks sensation—awake during surgery
- Median nerve contusion—leads to carpal tunnel
Flexmeter- brace you can use like a wrist guard for snow boarding/skiing
