Use of 2.0 mini plate system as reduction plate

Fracture stabilization and reduction using temporary plates during intramedullary tibial nailing was introduced as a novel concept in fracture surgery by Benirschke et al. (Orthop Trans 18:1055–1056, 1995). The concept of temporary reduction using one-third tubular plates proved useful in aiding metaphyseal and periarticular fracture fixation also. However, planning the strategic location of final plate was the main limitation with this technique using one-third tubular plates. We used 2.0 mini plates as provisional reduction plates that solved the issue of planning and placement of plates. The main advantage of our technique is that the final definitive plate can be applied directly over the mini plates. Here, we will describe our technique using relevant fracture case in metaphyseal–periarticular location.     

Effect of urethral plate characteristics on tubularized incised plate urethroplasty

PURPOSE: We determined outcomes of tubularized incised plate urethroplasty based on preoperative urethral plate configuration or width. MATERIALS AND METHODS: Records of consecutive prepubertal boys undergoing tubularized incised plate distal hypospadias repair were reviewed. The urethral plate was characterized as flat, cleft or deep, and results in each group were noted. In addition, the width of the plate after separation from the glans wings before midline incision was measured in some patients, with outcomes determined according to those less than 8 mm versus 8 mm or greater. RESULTS: Of 159 patients plate configuration was recorded in 143, widths in 48 and both in 46. Outcomes were determined at a mean of 8 months postoperatively. Overall, there were no cases of meatal stenosis and fistulas occurred in 3 patients (2%). No significant difference in results was predicted by plate configuration or width. CONCLUSIONS: Tubularized incised plate urethroplasty for distal hypospadias repair has a low complication rate regardless of urethral plate configuration or width. Therefore, this procedure is potentially applicable in all cases of primary distal hypospadias.     

A retrospective comparison of four plate constructs for first metatarsophalangeal joint fusion: static plate, static plate with lag screw, locked plate, and locked plate with lag screw

The primary treatment for progressive first metatarsophalangeal (MTP) joint arthritis is arthrodesis. Multiple fixation types have been used to accomplish fusion including plating. There have been no published articles reporting the outcomes of these 4 plate and/or screw constructs. We present our experience with 138 first MTP joint fusions using these constructs. A retrospective comparison and radiographic chart review of 132 patients (138 feet) was performed to compare different constructs in regards to successful union and time to fusion. All operations were performed by 4 fellowship-trained foot and ankle surgeons. The radiographs were independently read by 2 authors not involved in the index procedures. Radiographic fusion was determined by bridging cortices across the joint line. The mean time to union (in days) and rate of fusion were static plate: 59, 95%, static plate with lag screw: 56, 86%, locked plate: 66, 92%, and locked plate with lag screw: 53, 96%. There was not a statistically significant difference between the groups in regards to patient age, time to weight bearing, time to fusion, or rate of fusion. We report on the results of fusion comparing 4 different plate and/or screw constructs for first MTP joint fusion. The data reveal no significant difference in time to fusion or rate of fusion between static and locked plates, with or without a lag screw.     

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.     

Minimally invasive plate osteosynthesis of tibial fracture using self-navigated plate

This study aims to introduce a self-navigated plate, which is characterized by the presence of a groove at each end of the plate, in treating tibial fractures. The plate is inserted subperiosteally across the fracture line when the fracture is effectively reduced. A second plate of the same is then placed over the subcutaneous one and serves as a guide for percutaneous insertion of screws through the holes of subperiosteal plate into the bones to secure the fracture. Seven patients with tibial shaft fractures were treated by minimally invasive plate osteosynthesis (MIPO) using this plate. The average operative time was 47 min, and the average fluoroscopy time was 19 s. All fractures healed from 3 to 6 months postoperatively, and excellent functional recovery was observed in all patients. In conclusion, the economical-friendly self-navigated plate is a good and effective alternative fixation method in treating tibia fractures by MIPO.     

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.     

The growth plate

The growth plate is an organ composed of cartilage, bone, and fibrous parts whose activities are synchronized to provide for longitudinal growth in the typical long bone. The morphology, function, and metabolism of the growth plate and its component parts are discussed in detail in this article.
