Plating of tibial pilon fractures.

Successful treatment of pilon fractures requires a thorough understanding of the injury, proper timing of treatment, and use of the proper implant placed in the correct location. This article describes the factors involved in treatment decisions

The treatment of pilon fractures.

Soft tissue complications, skin slough, and superficial infection lead to deeper infection and amputation. By avoiding these complications, it is expected that better results can be obtained. Two techniques are available to do this. The first is to limit incisions and use external fixation to obtain stability. Even in these cases, care must be taken with the soft tissues. The second is a staged reconstruction, whereby stage one allows soft tissue stabilization. To this end, the fibula is plated, and transarticular external fixation is performed; this maintains anatomic length, preventing soft tissue contraction and permitting edema resolution. The second stage, formal tibial open reduction and internal fixation, is performed with plates and screws when operative intervention is safe. These methods appear to be equally effective in reducing major soft tissue complications. Surgeons should treat these complex fractures with the method with which they are most comfortable. Surgeons who feel comfortable with techniques of internal fixation are best qualified to perform open reductions. Surgeons who have experience with percutaneous fixation and hybrid external fixator application should use this method. Surgeons with limited or minimal experience with pilon fractures should consider fibula fixation and transarticular external fixation followed by transfer to an orthopedic trauma surgeon for definitive management

Treatment of long bone intramedullary infection using the RIA for removal of infected tissue: indications, method and clinical results.

Treatment of intramedullary infections of long bones is based upon the principles of surgical debridement, irrigation, fracture site stabilization, soft tissue coverage, and antibiotic administration. Reaming of the medullary canal is an essential component of surgical debridement because it removes intramedullary debris and infected bone surrounding the removed intramedullary device and within the intramedullary canal. The Reamer-Irrigator-Aspirator (RIA) has distinct features that appear to be beneficial for management of intramedullary infections. It allows reaming under simultaneous irrigation and aspiration, which minimizes the residual amount of infected fluid and tissue in the medullary canal and the propagation of infected material. The disposable reamer head is sharp, which combined with the continuous irrigation may attenuate the increased temperature associated with reaming and its potential adverse effects on adjacent endosteal bone. The disadvantage of the RIA is increased cost because of use of disposable parts. Potential complications can be avoided by detailed preoperative planning and careful surgical technique. The RIA should be used with caution in patients with narrow medullary canals and in infections involving the metaphysis or a limited part of the medullary canal. Reaming of the canal is performed with one pass of the RIA under careful fluoroscopic control. Limited information is available in the literature on the results of the RIA for management of intramedullary infections of long bones; however preliminary results are promising. The RIA device appears to be an effective and safe tool for debridement of the medullary canal and management of intramedullary infections of the long bones. Further research is needed to clarify the exact contribution of the RIA in the management of these infections

A staged protocol for soft tissue management in the treatment of complex pilon fractures.

OBJECTIVE: To determine whether open reduction and internal fixation of intra-articular pilon fractures using a staged treatment protocol results in minimal surgical wound complications. DESIGN: Retrospective. SETTING: Level 1 trauma center. PATIENTS/PARTICIPANTS: Between January 1991 and December 1996, 226 pilon fractures (AO types 43A-C) were treated, of which 108 were AO type 43C. Fifty-six fractures were included in a retrospective analysis of a treatment protocol. Injuries were divided into Group I, thirty-four closed fractures, and Group II, twenty-two open fractures (three Gustilo Type 1, six Type II, eight Type IIIA, and five Type IIIB). METHODS: The protocol consisted of immediate (within twenty-four hours) open reduction and internal fixation of the fibula when fractured, using a one-third tubular or 3.5-millimeter dynamic compression plate and application of an external fixator spanning the ankle joint. Patients with isolated injuries were discharged after initial stabilization and readmitted for the definitive reconstruction. Polytrauma patients remained hospitalized and were observed. Formal open reconstruction of the articular surface by plating was performed when soft tissue swelling had subsided. Complications were defined as wound problems requiring hospitalization. All affected limbs were then evaluated via chart and radiograph review, patient interviews, and physical examination until surgical wound healing was complete, for a minimum of twelve months. RESULTS: Group 1 (closed pilon): Follow-up was possible in twenty-nine out of thirty fractures (97 percent). Average time from external fixation to open reduction was 12.7 days. All wounds healed. None exhibited wound dehiscence or full-thickness tissue necrosis requiring secondary soft tissue coverage postoperatively. Seventeen percent (five out of twenty-nine patients) had partial-thickness skin necrosis. All were treated with local wound care and oral antibiotics and healed uneventfully. There was one late complication (3.4 percent), a chronic draining sinus secondary to osteomyelitis, which resolved after fracture healing and metal removal. Group II (open pilon): Follow-up was possible in seventeen patients with nineteen fractures (86 percent). Average time from external fixation to formal reconstruction was fourteen days (range 4 to 31 days). By definition, all Gustilo Type IIIB fractures required flap coverage for the injury. Two patients experienced partial-thickness wound necrosis. These were treated with local wound care and antibiotics. All surgical wounds healed. There were two complications (10.5 percent), both deep infections. One Type I open fracture developed wound dehiscence and osteomyelitis requiring multiple debridements, intravenous antibiotics, subsequent removal of hardware, and re-application of an external fixator to cure the infection. One Type IIIA open fracture of the distal tibia and calcaneus developed osteomyelitis and required a below-knee amputation. CONCLUSION: Based on our data, it appears that the historically high rates of infection associated with open reduction and internal fixation of pilon fractures may be due to attempts at immediate fixation through swollen, compromised soft tissues. When a staged procedure is performed with initial restoration of fibula length and tibial external fixation, soft tissue stabilization is possible. Once soft tissue swelling has significantly diminished, anatomic reduction and internal fixation can then be performed semi-electively with only minimal wound problems. This is evidenced by the lack of skin grafts, rotation flaps, or free tissue transfers in our series. This technique appears to be effective in closed and open fractures alike

The Antibiotic Nail in the Treatment of Long Bone Infection: Technique and Results.

Antibiotic cement nails provide a useful and relatively simple technique to treat intramedullary osteomyelitis of the long bones. These devices provide stability as well as local, targeted antibiotics, which are both critical aspects of osteomyelitis management. Additionally, the use of a threaded core is a critical component of successful cement nail assembly. With adherence to the simple principles outlined in this review, surgeons can expect reliably good results using these drug-delivery implants

Fractures of the tibial plafond.

Tibial plafond fractures comprise a diverse group of articular, metaphyseal, and occasionally diaphyseal injuries and have in common injury to the articular surface of the distal tibia and significant associated soft-tissue injury. Injury to the soft tissues combined with the complex fracture patterns has led to high complication rates from surgical attempts to reduce and stabilize these fractures. Currently, there is a wide range of treatment techniques available for a wide spectrum of injury severity, surgeon experience, and surgeon preferences. Patient outcomes vary widely. Because these injuries are relatively uncommon, the amount of clinical data available to guide treatment decisions is limited. Careful classification and assessment of the fracture pattern and associated soft-tissue injury and an understanding of the principles of modern concepts of treatment should allow the surgeon to choose from among several treatment protocols, all of which emphasize minimizing complications to optimize patient outcomes

Propionibacterium acnes Infection of the Shoulder After a Manipulation Under Anesthesia for Stiffness Status Post Open Reduction and Internal Fixation Proximal Humerus: A Case Report.

INTRODUCTION: Propionibacterium acnes infection has been more frequently recognized as an important cause of post-operative shoulder infection. Infection by this organism is more frequently seen after total shoulder arthroplasty but can also be seen after an open reduction and internal fixation (ORIF) of the proximal humerus. We present a patient with P. acnes infection of the shoulder that only became apparent after he underwent a manipulation under anesthesia for stiffness of the shoulder after an ORIF. CASE REPORT: Our patient was a 64-year-old male who sustained a proximal humerus fracture after a motorcycle collision and underwent an ORIF of the proximal humerus with plate fixation. Postoperatively, the patient had stiffness of the shoulder so he underwent a manipulation under anesthesia of the shoulder. On post-operative day 5, the patient developed an erythematous area over the incision. This area opened up and began to drain by post-operative day 10. The patient underwent an irrigation and debridement of the shoulder with partial removal of hardware. He was also started on antibiotics and clinically cleared his infection. CONCLUSION: Infection by P. acnes can be difficult to diagnose and may present with shoulder stiffness as the only initial symptom. This case is unique as there have not been any documented cases of a latent P. acnes infection presenting after a manipulation under anesthesia of the shoulder. There must be a high clinical suspicion for P. acnes infection in any patient presenting with post-operative stiffness

Long-term Bisphosphonate Therapy-induced Periprosthetic Femoral Stress Fracture in a Sliding Hip Screw Implant: A Unique Case Report.

INTRODUCTION: Long-term bisphosphonate therapy for osteoporosis is associated with an increased risk of low-to-no energy atypical subtrochanteric and femoral shaft fractures with characteristic radiologic findings. There are few reports of patients with long-term bisphosphonate-induced periprosthetic fractures, all of them had a hip arthroplasty prosthesis. In this report, we present a unique case of a 90-year-old Caucasian female on long-term bisphosphonate therapy with a sliding hip screw implant who sustained a periprosthetic fracture of the femoral shaft at the distal aspect of the plate. CASE REPORT: In April 2014, a 90-year-old female presented with left thigh pain after a fall from standing height. She had a previous fixation of a left intertrochanteric hip fracture with a sliding hip screw in 1999 and a 9-year history of bisphosphonate therapy. Radiographs obtained in the emergency department revealed a left-sided femoral shaft fracture at the distal aspect of the previously applied five-hole side plate. Of note, the periprosthetic fracture demonstrated cortical thickening at the fracture site of the lateral femoral cortex, lack of comminution as well as a transverse appearance. The patient was taken to the operating room the next day for retrograde placement of an intramedullary nail of the left femur with revision of left intertrochanteric femur fracture fixation. By 3 months postoperatively, she had obtained full radiographic union. CONCLUSION: This case report highlights the possibility of an atypical fracture distal to the sliding hip screw implant after open reduction internal fixation of an intertrochanteric hip fracture in patients on long-term bisphosphonates

Strangulation of Radial Nerve Within Nondisplaced Fracture Component of Humeral Shaft Fracture.

Rates of radial nerve injury, which is commonly associated with humeral shaft fractures, range from 8% to 12%. This neurapraxia typically recovers with nonoperative management. In some conservatively treated cases, the radial nerve is lacerated or entrapped. Patients with a lacerated or entrapped nerve may have better outcomes with early operative management. We report on a rare case of the radial nerve entrapped within a nondisplaced segment of a closed humeral shaft fracture and describe the clinical outcome of early operative management
