Fibula Rod System

Product Overview

The Acumed Fibula Rod System offers an alternative approach to traditional fibular plating by providing fracture stability with a minimally invasive surgical technique. Utilizing a targeting guide, the fibula rod and interlocking screws can be inserted through small incisions, which may help minimize valuable surgery room time.

The Fibula Nail for Treatment of Ankle Fractures in Elderly and High Risk Patients

Publication Excerpt

“The fibula nail provides an alternative to standard plate fixation that uses a minimal approach and, therefore, decreases the incidence of wound infection and the need for further surgery to remove prominent metalwork while providing stable fixation.”

Journal Abstract

Ankle fractures in the elderly are increasing in incidence, and comorbidities, including diabetes, steroid use, and osteoporosis, can make these injuries difficult to treat in this population. Prominent metal work, infection, and wound problems are common complications. The fibula nail provides an alternative to standard plate fixation that uses a minimal approach and, therefore, decreases the incidence of wound infection and the need for further surgery to remove prominent metalwork while providing stable fixation.

The Treatment of Unstable Fractures of the Ankle Using the Acumed Fibular Nail: Development of a Technique

Publication Excerpt

“Nailing of the fibula using our current technique gives good radiological and functional outcomes with minimal complications, and should be considered in the management of patients with an unstable ankle fracture.”

Journal Abstract

Techniques for fixation of fractures of the lateral malleolus have remained essentially unchanged since the 1960s, but are associated with complication rates of up to 30%. The fibular nail is an alternative method of fixation requiring a minimal incision and tissue dissection, and has the potential to reduce the incidence of complications.

The team reviewed the results of 105 patients with unstable fractures of the ankle that were fixed between 2002 and 2010 using the Acumed fibular nail. The mean age of the patients was 64.8 years (22 to 95), and 80 (76%) had significant systemic medical comorbidities. Various different configurations of locking screw were assessed over the study period as experience was gained with the device.

Nailing without the use of locking screws gave satisfactory stability in only 66% of cases (4 of 6). Initial locking screw constructs rendered between 91% (10 of 11) and 96% (23 of 24) of ankles stable. Overall, seven patients had loss of fixation of the fracture and there were five postoperative wound infections related to the distal fibula. This led to the development of the current technique with a screw across the syndesmosis in addition to a distal locking screw.

In 21 patients treated with this technique there have been no significant complications and only one superficial wound infection. Good fracture reduction was achieved in all of these patients. The mean physical component Short-Form 12, Olerud and Molander score, and American Academy of Orthopaedic Surgeons Foot and Ankle outcome scores at a mean of six years post-injury were 46 (28 to 61), 65 (35 to 100) and 83 (52 to 99), respectively. There have been no cases of fibular nonunion.

Nailing of the fibula using our current technique gives good radiological and functional outcomes with minimal complications, and should be considered in the management of patients with an unstable ankle fracture.

Fluoroscopy-Guided Reduction and Fibular Nail Fixation to Manage Unstable Ankle Fractures in Patients With Diabetes: A Retrospective Cohort Study

Publication Excerpt

“Fluoroscopy-guided reduction and fibular nail fixation of unstable ankle fractures in patients with diabetes was associated with a low incidence of wound and overall complications, while providing effective surgical fixation.”

Journal Abstract

Aims
Patients with diabetes are at increased risk of wound complications after open reduction and internal fixation of unstable ankle fractures. A fibular nail avoids large surgical incisions and allows anatomical reduction of the mortise.

Patients and Methods
The team retrospectively reviewed the results of fluoroscopy-guided reduction and percutaneous fibular nail fixation for unstable Weber type B or C fractures in 24 adult patients with type 1 or type 2 diabetes. The re-operation rate for wound dehiscence or other indications such as amputation, mortality, and functional outcomes was determined.

Results
Two patients developed lateral side wound infection, one of whom underwent wound debridement. Three other patients required re-operation for removal of symptomatic hardware. No patient required a below-knee amputation. Six patients died during the study period for unrelated reasons. At a median follow-up of 12 months (7 to 38) the mean Short Form-36 Metal Component Score and Physical Component Score were 53.2 (95% confidence intervals (CI) 48.1 to 58.4) and 39.3 (95% CI 32.1 to 46.4), respectively. The mean Visual Analogue Score for pain was 3.1 (95% 1.4 to 4.9). The mean Ankle Osteoarthritis Scale total score was 32.9 (95% CI 16.0 to 49.7).

Conclusions
Fluoroscopy-guided reduction and fibular nail fixation of unstable ankle fractures in patients with diabetes was associated with a low incidence of wound and overall complications, while providing effective surgical fixation.

Key Features

Minimally Invasive
The nail is inserted in the distal fibula through a minimal incision. Screws are inserted by making stab incisions to protect the soft tissue envelope and preserve vascularity of the periosteum.
Anatomically Contoured
The nail has a 5° bend designed to fit the intramedullary canal of the fibula.
Streamlined Procedure
The surgical technique consists of 8 steps from start to finish, streamlining valuable surgery time.
Targeting Guide
The targeting guide aids in the anatomic placement of both A/P and M/L screws and allows for syndesmotic screw fixation.

Case Study: Open Reduction of the Lateral Malleolus

A 76-year-old woman stepped off a curb and twisted her right ankle. Due to swelling and blistering, the surgeon chose to use Acumed's Fibula Rod System to treat the fracture of the lateral malleolus.
