– Discussion: – demonstrates intra-articular extension of frx – degree of comminution of posterior facet; – calcaneocuboid joint; – impingement of lateral border of calcaneus on lateral malleolus and entrapment of tendons or nerves can be demonstrated; – latter is best seen … Read more
– Facial Fractures and Upper Airway Injuries: – in pts with major frxs of the mandible and maxilla (Lefort III) in whom massive edema has yet to occur, oral intubation is preferred, and if required is usually easily accomplished; – blind nasal intubation following major facial injury is discouraged because of … Read more
– Discussion: – the Coventry type of HTO, creates an osteotomy above the tibial tubercle; – in choosing a closing wedge osteotomy, the surgeon should be sure that the major deformity is on the tibial side (vs femoral side); – the disadvantages of this type of osteotomy include possible … Read more
Origin: tip of coracoid process on scapula; Insertion: middle of medial border of humerus, opposite deltoid tuberosity; action: horizontal flexion and adduction of the humerus at the shoulder; synergists: pectoralis major, biceps brachi, and anterior deltoid; nerve supply: musculocutaneous, C6, C7; – Surgical Hazards: – profunda gives off muscular branches, usually gives rise to … Read more
– Discussion: – can reduce back and knee pain; – improved ability to sit for longer periods of time; – increased incidence of dislocation; – indications for conversion: – painful pseudarthrosis – pseudorthrosis rates … Read more
– Discussion: – stenosing tenosynovitis of the flexor pollicis longus in childhood is relatively uncommon condition which causes triggering, IP joint flexion contracture, and a flexor tendon nodule over the metacarpal head level (Notta’s nodule); – although present at birth, dx often not made until 4-6 months of age – … Read more
– Detached Deltoid: – deltoid tendon & muscle that are reattached to raw acromial bone edge can pull away if they are improperly attached – if deltoid detachment occurs, it should be repaired as soon as possible, because if fixed contracture of deltoid develops little can be done; – Axillary Nerve Injury: … Read more
– Discussion: – at time of the injury, calcaneus is driven up toward center of body; – lateral wall is driven outward, as are the peroneal tendons; – this results in shortened functional length of gastrocnemius-soleus complex, flat foot, lateral impingement of peroneal structures, & locked … Read more
– Discussion: – osteonecrosis of proximal fragment; – non union if proximal fragment is too thin; – delayed union or nonunion occurs in 1-3% of pts & is treated by bone grafting or by repeat osteotomy when correction is lost; – ref: Results … Read more
– Antebrachial Compartment Syndrome: (see compartment syndrome menu) – causes: – may follow supracondylar fr(x) of humerus, or both bone forearm fractures; – compartment syndromes in the forearm after wrist fractures usually involve the volar compartment; – compartment syndrome monitoring – technique of forearm fasciotomy: (see … Read more
