Operative Techniques

E

Preoperative Plan

  • describe potential complications and steps to avoid them
F

Room Preparation

1

Surgical Instrumentation

  • Intramedullary humeral nail system

2

Room setup and Equipment

  • standard OR table

3

Patient Positioning

  • beach chair position
  • place a small roll between the medial borders of the scapula
  • turn the head to the contralateral side
G

Approach

1

Palpate and outline the anatomy of the humerus, clavicle and the humeral head

  • identify and mark out the midline

2

Make the skin incision

  • make a small longitudinal incision over the anterolateral corner of the acromion centered over the greater tuberosity
  • extend the incision distally 3 cm

3

Perform skin incision

  • use 10 blade for skin incision

4

Divide the deltoid

  • split the deltoid fibers in line with the longitudinal incision
  • do not extend the incision more than 4 cm because of the axillary nerve
  • use knife down to fascia lata

5

Reflect the supraspinatus

  • longitudinally incise the the supraspinatus in line with the skin incision for 1 to 2 cm just posterior to the bicipital tuberosity
  • place suture tags
H

Canal Entry

1

Make the entry hole

  • make the entry hole just medial to the to of the greater tuberosity, just lateral to the articular margin and 0.5 cm posterior to the bicipital groove
  • make sure the entry hole is centered on AP and Lateral radiographs

2

Place the Kwire

  • insert the kwire into the medullary canal to the level of the lesser tuberosity

3

Open the medullary canal

  • use an awl or pass a cannulated drill bit over the kwire
  • extend the shoulder to improve clearance of the acromion
  • once the canal is opened, remove the kwire and place a ball tip guidewire

4

Advance the guidewire

  • advance the guidewire until it is 1 to 2 cm proximal to the olecranon fossa
I

Determine Nail Length

1

Guide rod method

  • with the distal end of the rod 1 to 2 cm proximal to the olecranon fossa, overlap a second guide rod extending proximally from the humeral entry portal
  • subtract the length in mm of the overlapped guide rod from the total length of the identical guidewire to determine the nail length

2

Nail length gauge

  • place the radioopaque gauge anterior to the humerus
  • move the the C-arm to the proximal end of the humerus
  • read the length from the stamped measurements on the gauge
J

Reaming and Nail Insertion

1

Ream the humeral shaft

  • slowly ream the entire humerus over the ball tipped guidewire in 0.5 mm increments
  • choose a nail that is 1 mm smaller than the last reamer used

2

Insert the nail

  • attach the nail to an adaptor
  • place the nail holding screw through the adaptor
  • place the radiolucent targeting device onto the nail adaptor

3

Verify the nail assembly

  • insert a drill bit through the assembled tissue protector placed in the required holes of the targeting device

4

Advance the nail

  • manually advance the nail with sustained pressure
  • insert the nail to at least the first circumferential groove on the nail adaptor but no deeper than the second groove
  • countersink the nail 5 mm below the articular surface
K

Distal Locking Screws

1

Place the interlocking screws in a specific order

  • place anterior, then posterior, then lateral then medial directed interlocking screws

2

Place the anterior-posterior screws

  • advance the C arm over the distal humerus until the oval slot is seen in a perfect circle
  • use a scalpel over the skin to precisely determine the location of the incision
  • keep incision lateral to the biceps tendon
  • after skin incision use a blunt hemostat to spread under the brachialis muscle
  • insert a short drill bit through a soft tissue protector
  • center the drill bit in the locking hole hole
  • attach the drill and penetrate the near cortex
  • detach the drill bit then use a mallet to advance the drill bit to the far cortex
  • reattach the drill and penetrate the far cortex
  • place a depth gauge and measure the length of the interlocking screws
  • place the interlocking screws
  • use C arm to confirm placement and length

3

Place the lateral-medial screws

  • advance the C arm over the distal humerus until the oval slot is seen in a perfect circle
  • use a scalpel over the skin to precisely determine the location of the incision
  • after skin incision use a blunt hemostat to spread to the bone
  • insert a short drill bit through a soft tissue protector
  • center the drill bit in the locking hole hole
  • attach the drill and penetrate the near cortex
  • detach the drill bit then use a mallet to advance the drill bit to the far cortex
  • reattach the drill and penetrate the far cortex
  • place a depth gauge and measure the length of the interlocking screws
  • place the interlocking screws
  • use C arm to confirm placement and length
L

Wound Closure

1

Repair the supraspinatus and deltoid

  • use nonabsobable suture to perform a side to side repair

2

Close the deep fascia

  • use 0 vicryl for deep fascia

3

Perform superficial closure

  • use 3-0 vicryl for subcutaneous tissue
  • use 3-0 nylon for skin

4

Dressings

  • place soft dressings
  • place in sling or shoulder immobilizer
