Use of External Fixation and Primary Wound Closure in an Open Comminuted First Metatarsal Fracture: A Case Report

Management of open, comminuted fractures presents a challenge for the foot and ankle surgeon. Reconstructive surgery for such injuries has a high potential for the development of serious complications, and factors such as the extent of soft tissue injury, neurovascular status to the foot, and fracture stability must be taken into consideration before determining a surgical plan. This article describes the case of a patient who presented with an open, comminuted first metatarsal fracture as a result of a chainsaw injury. The patient was treated with a uniplanar mini-external fixator, demineralized bone matrix, primary wound closure, and external bone growth stimulation. At 1-year follow-up, the interview and examination revealed the patient to be pain free with a functional first ray. ACFAS Level of Clinical Evidence: 4.     

A Rare Fracture,an Even Rarer Treatment: The Arthroscopic Reduction and Internal Fixation of an Isolated Femoral Head Fracture

This case report describes the first documented arthroscopic reduction and internal fixation of a rare isolated femoral head fracture without associated dislocation. A large suprafoveal osteochondral fracture was arthroscopically reduced by use of crossover techniques gained from experience performing arthroscopic femoroacetabular impingement surgery. An innovative “chopstick” maneuver was used to rotate the mobilized osteochondral fragment into anatomic position, followed by arthroscopic Herbert screw fixation. Relevant surgical techniques and clinical outcome are presented. Although this case shows arthroscopic osteosynthesis for a rare fracture, the techniques described herein may permit broader arthroscopic applications. As hip arthroscopy evolves, the role of arthroscopic surgery in the traumatized hip may expand beyond diagnostic arthroscopy and foreign/loose body removal. An anatomic reduction with stable internal fixation permitting early joint motion trumps the ability to perform outpatient arthroscopic procedures. However, if the equivalent procedure can indeed be accomplished in a safe and minimally invasive manner, one can envision a future expansion of the role of hip arthroscopic surgery in fracture management.     

Fractures of the Proximal Fifth Metatarsal: Percutaneous Bicortical Fixation

Background

Displaced intraarticular zone I and displaced zone II fractures of the proximal fifth metatarsal bone are frequently complicated by delayed nonunion due to a vascular watershed. Many complications have been reported with the commonly used intramedullary screw fixation for these fractures. The optimal surgical procedure for these fractures has not been determined. All these observations led us to evaluate the effectiveness of percutaneous bicortical screw fixation for treating these fractures.

Methods

Twenty-three fractures were operatively treated by bicortical screw fixation. All the fractures were evaluated both clinically and radiologically for the healing. All the patients were followed at 2 or 3 week intervals till fracture union. The patients were followed for an average of 22.5 months.

Results

Twenty-three fractures healed uneventfully following bicortical fixation, with a mean healing time of 6.3 weeks (range, 4 to 10 weeks). The average American Orthopaedic Foot & Ankle Society (AOFAS) score was 94 (range, 90 to 99). All the patients reported no pain at rest or during athletic activity. We removed the implant in all cases at a mean of 23.2 weeks (range, 18 to 32 weeks). There was no refracture in any of our cases.

Conclusions

The current study shows the effectiveness of bicortical screw fixation for displaced intraarticular zone I fractures and displaced zone II fractures. We recommend it as one of the useful techniques for fixation of displaced zone I and II fractures.

Nonunion of a Pediatric Distal Radial Metaphyseal Fracture Following Open Reduction and Internal Fixation

Abstract A boy, age 9, presented with deformation and pain of the left distal forearm, 1 year after a plate osteosynthesis for a distal radial metaphyseal fracture. This case showed a pediatric nonunion of a distal radial metaphyseal fracture which caused strong deformation of the left distal forearm. This is an extremely rare complication in children following an open reduction and internal fixation for a displaced distal forearm fracture. Key points of pediatric fracture healing are discussed and a review of the literature is given.

Complications,Reoperations, and Long-Term Outcomes after Open Reduction Internal Fixation of Mason Classification Type II and Type III Radial Head Fractures

Introduction  The objectives of this study were to assess long-term outcomes, complications, and reoperations after open reduction internal fixation (ORIF) of radial head fractures. Materials and Methods  35 adult patients, who underwent ORIF of an isolated, displaced radial head fracture without elbow instability (Mason classification type II or III) at two tertiary care referral centers from 2000 to 2017, were identified. Patient satisfaction, pain, and QuickDASH scores were assessed by telephone follow-up at median 12.9 years. Results  The mean age of the 35 patients in our study was 39 years, and 54% were women. The median length of clinical follow-up was 175 days. Postoperative complications occurred in 54% of patients, and reoperations in 23% of patients. Multivariable logistic regression identified fixation with plate and screws versus screws alone as a risk factor for complications and reoperations. The long-term telephone follow-up response rate was 54%. At 13-year median follow-up, the average patient satisfaction was 9.6/10, the average patient-reported pain was 0.7/10, and the average QuickDASH score was 10.5. Conclusion  The long-term outcomes of ORIF of Mason classification type II and III radial head fractures are favorable; however, rates of complication and reoperation are notable and may be higher with plate-and-screw fixation.

Comparison of the Outcomes Between Headless Cannulated Screw Fixation and Fixation Using a Locking Compression Distal Ulna Hook Plate in Fracture of Fifth Metatarsal Base

The aim of the present study was to evaluate and compare the clinical and radiologic results of internal fixation with a headless cannulated screw versus a locking compression distal ulna hook plate for fractures at the base of the fifth metatarsal bone, zone 1. From April 2012 to April 2015, 30 cases (29 patients) were retrospectively evaluated. The mean follow-up period was 13 months. The patients were divided into 2 groups stratified by the fixation method: screw (group A, n = 15) or plate (group B, n = 15). We measured the displacement to diastasis of the fracture on the foot oblique radiographs taken pre- and postoperatively in each group, recorded the time to bony union, and measured the difference in the reduction distance in each group. The clinical results were evaluated using the American Orthopaedic Foot and Ankle Society midfoot score at 12 months postoperatively. In group A, the mean interval to union was 54.2 ± 9.3 days, the mean displacement to diastasis had improved to 0.3 ± 0.4 mm postoperatively (p < .001), and the mean reduction distance was 2.9 ± 1.0 mm postoperatively. In group B, the mean interval to union was 41.5 ± 7.0 days, the mean displacement to diastasis had improved to 0.06 ± 0.2 mm postoperatively (p < .001), and the mean reduction distance was 4.1 ± 1.6 mm. The American Orthopaedic Foot and Ankle Society midfoot scale score was 97.7 ± 3.4 in group A and 98.2 ± 3.2 in group B. The interval to union was significantly different between the 2 groups (p = .01). No complications were recorded. Our findings have shown that the plate is a reasonable and alternative method for the surgical treatment of fifth metatarsal base fractures.
