Sharing of Information
• Upper extremity injuries 30-40% of peripheral vascular injuries
• 15-20% of peripheral vascular traumas
-ulnar and radial arteries
• Penetrating trauma -most common cause
![Page 33: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/33.jpg)
Assessment and Management of Extremity Injuries
• Trauma to the extremities falls into two basic categories – penetrating (vascular or neurologic injury)– blunt (fractures and the soft tissue injuries)
• Unless active bleeding is present, injuries to the extremities are less urgent than injuries to the trunk, the head, or the neck
![Page 34: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/34.jpg)
Assessment and Management of Extremity Injuries
• most extremity injuries are not immediately life-threatening and thus can be treated more deliberately
• Massive Hemorrhage: goal is to control bleeding and transport to the OR
![Page 35: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/35.jpg)
Initial Assessment
• History
• PE
• Time of Injury if vessels are involved
• Mechanism of Injury
• Presence of major vascular injury
![Page 36: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/36.jpg)
Initial Assessment
• The initial examination should first be directed toward the circulation
• Blood pressure and temperature in both the injured limb and its contralateral counterpart should be determined
![Page 37: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/37.jpg)
Initial Assessment
• The circulatory examination should be followed first by a quick neurologic examination aimed at assessing motor function in the hands and feet
• Ascertain the presence or absence of sensation and later by a proximal examination of sensory and motor function
![Page 38: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/38.jpg)
Initial Assessment
• Gross deformity is pathognomonic of fracture or dislocation
• Soft tissue defects should be noted
• If oozing is present, particularly in the hand, proximal application of a tourniquet– may facilitate examination– permit definitive control of the bleeding point– determine nerve, muscle, or tendon
![Page 39: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/39.jpg)
Injuries to Blood Vessels
• Arterial injuries in an upper extremity are generally a less demanding problem than corresponding injuries in a lower extremity
• main reasons:– that upper extremity vessels have much better
collateral flow– remain viable except when extensive soft
tissue damage is present
![Page 40: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/40.jpg)
Injuries to Blood Vessels
• Injuries from blunt trauma usually result in thrombosis of a vessel
• Penetrating injuries that completely divide the vessel may be manifested by thrombosis rather than hemorrhage
• If the vessel is only partially divided, it contracts and will continue to bleed.
• Partial transections are more dangerous than complete ones
![Page 41: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/41.jpg)
Injuries to Blood Vessels
• If the location of the penetrating injury is obscure or if multiple injuries may exist, angiographic or ultrasonographic evaluation may be appropriate
• Extremity arteriography in the OR can be performed by injection into the axillary artery (for upper extremity injuries) or the common femoral artery (for lower extremity injuries).
![Page 42: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/42.jpg)
Injuries to Blood Vessels
• Exposure of the x-ray plate immediately after injection of 15 to 20 ml of full-strength contrast material usually results in visualization of the injured area
![Page 43: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/43.jpg)

Injuries to Blood Vessels
• Hard signs
-indicative of an underlying arterial injury
-requires immediate operative exploration and repair.
• Soft signs
-further evaluation • Critical time for restoration of perfusion is 6-8
hours following extremity vascular trauma
![Page 47: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/47.jpg)
Complications
• Occlusion and bleeding -early complications -necessitate reoperation.
• Muscle edema• Nerve injury • Arteriovenous fistulas and false
aneurysms -late complications
![Page 48: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/48.jpg)
TENDON INJURIES
• Flexor tendon injuries cause less impairment of hand function than extensor tendon injuries
• This is mainly due to the redundancy of the flexor tendons in the hand
• Flexor tendon lacerations should always be repaired in the operating room because the synovial sheaths predispose to serious infections
![Page 49: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/49.jpg)
TENDON INJURIES
Table 1 - Classification of Flexor Tendon Injury
Zone Description
I Flexor digitorum superficialis inserts into the profundus tendon and the base of the distal phalanx
II
From the MCP to the DIP joint of the fingers
III
Extends from the exit of the carpal tunnel to the MCP joint
IV
Includes the wrist and carpal tunnel
V
Forearm
![Page 50: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/50.jpg)
• Any flexor tendon lacerations should be repaired by a hand surgeon within 12 hours
• But they can be splinted with the fingers flexed for delayed repair within four weeks. This is not as favorable, however, as having the tendon repaired within the first 12 hours.
![Page 51: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/51.jpg)
• Medical therapy: -IV antibiotics when indicated-tetanus immunization
• Surgical therapy: All flexor tendons should be repaired in the OR • Hemostasis• Irrigation• Debridement are of vital importance. Debris and nonviable tissue left within the wound are niduses for infection,
which can severely compromise the final range of motion.
![Page 52: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/52.jpg)
Injuries to Nerves
• Nerve injury has always been the most challenging aspect of managing trauma to the extremities
• It is the principal factor that accounts for limb loss and permanent disability
• Some nerve injuries, such as brachial plexus injuries and nerve root injuries, preclude repair
![Page 53: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/53.jpg)

Objective
• To know the cause, mechanism and the effects of early controlled mobilization after flexor tendon repair and to assess the range of active motion after flexor tendon repair in hand.
![Page 65: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/65.jpg)
Methods:
• This study was conducted at the department of Plastic Surgery, Pakistan Institute of Medical Sciences, Islamabad from 1st March 2002 to 31st August 2003. Only adult patients of either sex with an acute injury were included in whom primary or delayed primary tendon repair
was undertaken.
![Page 66: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/66.jpg)
• In all the patients, modified Kessler’s technique was used for the repair using
non-absorbable monofilament (Prolene 4-0). The wound was closed with interrupted nonabsorbable, polyfilament (Silk 4-0) suture.
![Page 67: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/67.jpg)
• Passive movements of fingers were started from the first post operative day, and for controlled, active movements, a dynamic splint was applied.
![Page 68: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/68.jpg)
Results
• Laceration with sharp object was the most frequent cause of injury.
• Finger tip to distal palmer crease distance (TPD) was < 2.0 cm in 71% cases (average 2.4cm) at the end of 2nd postoperative week.
![Page 69: Case Presentation, Management, Discussion and Sharing of Information on Skin and Soft Tissue Trauma Jonathan Malabanan, M.D. Surgery Resident OMMC.](https://reader038.fdocuments.us/reader038/viewer/2022110205/56649cd75503460f9499e9ae/html5/thumbnails/69.jpg)
Results
• TPD was < 2.0 cm in 55% patients
and < 1.0 cm in 38% cases (average 1.5cm) at the end of 6th week.
• Total 9 patients were lost to the follow up at the end of 8th week.
• TPD was < 1.0 cm in 67% (average 0.9cm) at the end of 8th postoperative week. No case of disruption of repair was noted during the study.

Conclusion
• Early active mobilization programme is essential after tendon repair. Majority of the patients (92%) had fair to good results at the end of 2nd week which increased to 97% at the end of 8th week to good to
excellent.
