Innovations in locking plate technology

Plating techniques remain the mainstay for managing most periarticular and selected long bone fractures. However, movement toward more biologically appropriate plating techniques is occurring in an attempt to minimize soft-tissue stripping, decrease the need for bone grafting, and improve union rates. Internal fixation with locking plates creates a toggle-free, fixed-angle construct. Early data on the biomechanical and clinical performance of these implants are encouraging. Current indications for locked plating include periarticular fractures, typically those with metaphyseal comminution. Although impressive union rates have been reported, malunion remains a concern, especially when percutaneous techniques are used. Further clinical and biomechanical research on locking plate technology is needed to define its place fully alongside existing technology in orthopaedic trauma.     

Minimally invasive periprosthetic plate osteosynthesis using the locking attachment plate

Objective

Stable fixation of periprosthetic or periimplant fractures with an angular stable plate and early weight bearing as tolerated.

Indications

Periprosthetic femur fractures around the hip, Vancouver type B1 or C. Periprosthetic femur and tibia fractures around the knee. Periprosthetic fractures of the humerus. Periimplant fractures after intramedullary nailing.

Contraindications

Loosening of prosthesis. Local infection. Osteitis.

Surgical technique

Preoperative planning is recommended. After minimally invasive fracture reduction and preliminary fixation, submuscular insertion of a large fragment femoral titanium plate or a distal femur plate. The plate is fixed with locking head screws and/or regular cortical screws where possible. If stability is insufficient, one or two locking attachment plates (LAP) are mounted to the femoral plate around the stem of the prosthesis. After fixing the LAP to one of the locking holes of the femoral plate, 3.5 mm screws are used to connect the LAP to the cortical bone and/or cement mantle of the prosthesis.

Postoperative management

Weight bearing as tolerated starting on postoperative day 1 is suggested under supervision of a physiotherapist.

Results

In 6 patients with periprosthetic fractures and 2 patients with periimplant fractures, no surgical complications (e.g., wound infection or bleeding) were observed. The mean time to bony union was 14 weeks. No implant loosening of the locking attachment plate was observed. At the follow-up examination, all patients had reached their prefracture mobility level.     

Posterior buttress plate with locking compression plate for Hoffa fracture

BackgroundMany difficulties are associated with treating fractures of the posterior condyle of the femur (Hoffa fractures). Anatomical reduction and internal fixation are optimum for such intra-articular fractures. Some surgeons use anteroposterior screws to achieve direct stability. However, screw fixation is not adequate in some cases. To increase stability, we treat Hoffa fractures with a posterior buttress plate; we use a twisted, 1/3 tubular plate at the posterior surface and a supplementary, locking compression plate (LCP) for additional stability.MethodsPatients who had sustained Hoffa fractures between January 2006 and March 2009 were included in this study. Patients comprised three males and two females with a mean age of 73.6 years at the time of surgery. A 3.5-mm 1/3 tubular plate was twisted and applied to the posterolateral aspect of the distal femur. This was combined with an LCP on the distal femur to achieve a rafting effect.ResultsAll fractures were healed within 15 weeks. There were no instances of nonunion, infection, or implant removal. The mean range of motion was ?3° to 121°. Four patients had no pain in the treated limb and one had mild pain on weight bearing. The average Oxford Knee Score was 44.6 points. All patients achieved satisfactory joint function and regained their walking ability with good clinical results.ConclusionsImproved stability associated with this technique enables patients to begin range-of-motion training and return to their normal activities sooner; this resulted in good outcome.

Steinmann pin augmentation versus locking plate constructs

BackgroundAggressive bone neoplasms, such as giant cell tumors, often affect the proximal tibia warranting bony resection via curettage leaving behind massive defects that require extensive reconstruction. Reconstruction is usually accomplished with poly(methyl methacrylate) (PMMA) packing supplemented with an internal fixation construct. The purpose of this study is to compare Steinmann pin augmentation to locking plate constructs to determine which offers the stiffer reconstruction option.ResultsLocking plate constructs (801.8 ± 78 N/mm) had greater (p = 0.041) stiffness than tibial constructs fixed with Steinmann pins (646.5 ± 206.3 N/mm).ConclusionsPermanent deformation was similar between the Pin and Plate group; however, two tibia from the Pin group exhibited displacements >5 mm which we considered failure.

Interprosthetic femoral fractures treated with locking plate

Purpose

Interprosthetic fractures are challenging to manage. Although treatment of femoral fractures around a single implant has been described, there is little literature for treatment of interprosthetic femoral fractures. This study analyses the management and outcomes of 15 patients with interprosthetic femoral fractures treated with locking plates.

Methods

A retrospective chart review was conducted of 17 patients with interprosthetic femur fracture treated with locking plates from 2002 to 2013. Patient demographics and comorbidities were collected. Preoperatively, patients were classified with the Vancouver or Su classification system. Intraoperative use of bone graft and/or cerclage cables was also examined. Clinical and radiographic outcomes were evaluated for union, time to full weight bearing, return to preinjury level of activity, and pain assessed with visual analog scale (VAS).

Results

There were 15 patients with interprosthetic fractures meeting criteria for this study. Average patient age was 80.53 (range, 61–92) years. Bone grafting was used in 23.5 % (four of 17) and cerclage cables in 29.4 % (five of 17). Patients achieved complete union and return to full weight bearing an average of 4.02 (range, two to six) months later. Average VAS pain score was 1.00 (range, zero to six). All patients returned to their preoperative ambulatory status.

Conclusion

Locking plates could achieve satisfactory results for interprosthetic fractures. Considering an individual’s fracture type, bone quality and protheses to determine the appropriate plate length and optional use of cerclage and/or bone graft was essential. In this limited sample size, interprosthetic fractures occurred at similar rates at the supracondylar region and diaphysis.     

Tibiotalocalcaneal arthrodesis using a femoral locking plate

The goal of a tibiotalocalcaneal arthrodesis is to create a pain-free, stable hindfoot and ankle. Although a reserved procedure, it is useful when simultaneous ankle and subtalar joint pathology exists. Numerous complications have been reported after tibiotalocalcaneal arthrodesis, most importantly nonunion. Locking plates have proved to be a more stable construct than alternative forms of arthrodesis. In the inverted positions, the hybrid plating of the femoral locking plate structurally aligns with the anatomy of the hindfoot. This provides an anatomically sound construct, while allowing for both locking and lag screw insertion. We describe a new technique using a 4.5-mm condylar plate for tibiotalocalcaneal arthrodesis.
