Primary internal fixation and bone grafting for open fractures of the hand

The Mangled Upper Extremity-Algorithm for Salvage: My Workhorse Flaps

Mangling injuries of the upper extremity are severe, high-energy traumas that damage multiple functional systems including skin, nerves, vascular, tendon, and bone. Management requires familiarity with various techniques in orthopedic, vascular, and plastic surgery. A specific technique cannot be described due to the various combinations of injuries that can occur with mangled upper extremities, but we present principles and recommendations for treatment and judgment.

Current concepts of bone grafting in trauma surgery

Bone graft in trauma surgery is commonly used in managing bone defects, non-union, fracture related infections, arthrodesis or to provide structural support in fractures. A variety of bone grafts are made available to the treating physician, which includes autograft, allograft and bone graft substitutes. The future of bone grafting in trauma surgery is exciting with the incorporation of technological advancement such as gene therapy, 3D-printing and tissue engineering. Regardless, there are still limitations to what we understand regarding current bone grafting techniques with conflicting literature on their clinical utility and indication. The aim of this review article therefore is to take a step back and critically evaluate the current concepts of bone grafting in trauma surgery, with special emphasis made on reviewing the types of bone graft, biology of bone graft incorporation and indication for its use in various clinical scenarios.

Open Fractures of the Hand: Review of Pathogenesis and Introduction of a New Classification System

Open fractures of the hand are a common and varied group of injuries. Although at increased risk for infection, open fractures of the hand are more resistant to infection than other open fractures. Numerous unique factors in the hand may play a role in the altered risk of postinjury infection. Current systems for the classification of open fractures fail to address the unique qualities of the hand. This article proposes a novel classification system for open fractures of the hand, taking into account the factors unique to the hand that affect its risk for developing infection after an open fracture.

"Damage Control" Hand Surgery: Evaluation and Emergency Management of the Mangled Hand

Mangled hand injuries are defined as those with significant damage to multiple structures, which may be limb threatening. Historically these injuries resulted in amputation or death, but modern surgical and perioperative advances allow for complex reconstruction and the possibility of a sensate and functional limb. Evaluation begins with surveying for life-threatening injuries followed by a systematic approach to identify injured structures; management begins with preserving all parts, minimizing warm ischemia time, performing débridement, and planning an operative approach to optimize the chance of a functional limb. With careful surgical planning and a well-executed reconstruction, most limbs can be salvaged.

Open fractures of the hand with soft tissue loss

The evaluation, initial treatment, and definitive reconstruction of open fractures of the hand with associated soft tissue loss are reviewed. Specific attention is given to the literature on open fracture antibiotic prophylaxis in the hand; the timing of bone and soft tissue reconstruction; and options for soft tissue coverage, including local, regional, and distant tissue transfer. Factors that have shown association with outcomes in these injuries are also discussed, and the authors' preferred management is summarized.

Corticocancellous olecranon autograft for metacarpal defect reconstruction: a case report

BACKGROUND

High-energy injuries to the hand frequently lead to bone defects as well as soft tissue loss. Early bone grafting of defects is well established in the literature; however, few options are available for autologous corticocancellous grafts. Most frequently cited studies describe the iliac crest or the distal radius donor sites.

METHODS

In this case report, we describe a new technique of obtaining corticocancellous bone graft from the olecranon.

RESULTS

Complete union of the segmental defect was achieved with this technique.

CONCLUSIONS

The olecranon donor site is outside the zone of injury and therefore safe to access, but within the upper extremity, thus avoiding the need for harvest from a distant site such as the iliac crest or the distal femur. Additional benefits of this site are the greater volume of graft that can be harvested compared to the distal radius as well as a more optimal ratio of cancellous to cortical graft available, compared to the iliac crest where the graft may be excessively cortical in nature.

Open intercondylar fractures of the distal humerus: Management using a mini-external fixator construct

Intercondylar fractures of the distal humerus are a challenging entity to treat. Open reduction-internal fixation with plating is well accepted as the standard treatment for these fractures, because it allows early mobilization and prevents joint stiffness. However, this technique may be associated with inferior postoperative results and a higher risk of infection in open fractures. External fixation appears to be an interesting option in such cases, where the results of open reduction-internal fixation with plating may be suboptimal. We present a bilateral uniplanar mini-external fixator construct for the treatment of open intercondylar distal humeral fractures. We managed 8 cases with this external fixation technique, with 6 of 8 patients achieving good to excellent results as determined by Cassebaum's rating system.

Primary bone grafting with pedicled flap cover for dorsal combined injuries of the digits

Twenty digits in 15 patients with dorsal combined tissue loss were treated by radical debridement, primary non-vascularised iliac crest bone graft and immediate lower abdominal flap cover between 1996 and 2006. The average length of the bone grafts was 3.3 (range 2.5-5) cm. No extensor tendon reconstruction was carried out. The flaps were divided at 3 weeks without delay. Permissible thinning of the flap was done at the time of division of flaps. No secondary procedure was done. All patients were retrospectively reviewed and X-rays obtained. Radiological union was achieved in 18 of 20 digits. One bone graft was removed because of infection. One bridging bone graft united with the distal phalanx but had a painless non-union with the proximal phalanx. There were no flap complications. Bone graft length resorptions of 20% and 15% occurred in two terminal bone grafts. We recommend this protocol as a solution to this challenging problem.
