Pre- and postoperative complications of adult forearm fractures treated with plate fixation

Adverse Events After Surgical Treatment of Adult Diaphyseal Forearm Fractures: a Retrospective Analysis of 470 Patients

Background

The incidence of and risk factors for adverse events after internal fixation of diaphyseal forearm fractures have not been well defined in the current literature. The objective of this study was to estimate the incidence of adverse events after diaphyseal forearm fracture surgery in adults and explore potential risk factors for adverse events.

Methods

We conducted a retrospective, multicenter, cohort study in which we evaluated all diaphyseal forearm fractures between 2009 and 2019 in patients presenting to 4 trauma hospitals in southern Finland. Patients <16 years of age and fracture-dislocations were excluded. There were 470 patients included in this study. Patient records were evaluated to identify and analyze adverse events.

Results

There were 202 patients with both-bone fractures, 164 patients with isolated ulnar fractures, and 104 patients with isolated radial fractures. In total, 146 patients (31%) experienced an adverse event; 83 (18%) had major adverse events (persistent or requiring surgical intervention). The patients underwent procedures performed by 185 different surgeons. The median number of operations for a single surgeon was 2 (range, 1 to 12). The most common major adverse events were plate and screw-related issues (6%), nonunion (5%), persistent nerve injuries (4%), and refractures (4%). Higher body mass index, Gustilo-Anderson type-II open fractures, both-bone fractures, isolated radial fractures, and operations performed by junior residents were found to be risk factors for adverse events in the multivariable analysis.

Conclusions

Adverse events after diaphyseal forearm fracture surgery are common. We recommend concentrating these operations in a limited team of surgeons and restricting inexperienced surgeons from operating on these fractures without supervision.

Is intramedullary pinning for isolated ulnar shaft fractures a surgical alternative to plate fixation?

INTRODUCTION

Unstable isolated ulnar shaft fractures are rare injuries that need to be surgically treated. The purpose of this study was to compare the functional and radiographic outcomes of two types of surgeries: closed reduction and intramedullary fixation (IMF) by pinning and open reduction and internal fixation (ORIF).

HYPOTHESIS

Our hypothesis was that IMF obtained similar outcomes to ORIF.

MATERIALS AND METHODS

All patients treated for an isolated distal or middle third ulnar shaft fracture between 2016 and 2019 were enrolled into two groups: ORIF and IMF. The technique performed depended on the surgeon's preference and not the type of fracture or patient. Demographic and clinical data (QuickDASH) and complications were retrospectively collected. X-rays were also examined to classify the fracture, assess postoperative reduction quality, and determine the amount of shortening and angulation.

RESULTS

A total of 81 patients with a mean age of 34 years were divided into two groups: 34 in ORIF and 47 in IMF. The two groups had similar demographics, mechanisms of injury, and preoperative fracture characteristics. The only difference was smoking (p<0.001). Despite a greater mean ulnar shortening of 0.4 mm in the IMF group (p=0.048), there were no significant differences regarding the functional score (QuickDASH) and rate of pseudarthrosis. However, the operative time (p<0.001) was shorter in the IMF group.

DISCUSSION

In the treatment of unstable isolated ulnar shaft fractures, IMF and ORIF had similar clinical and radiographic outcomes in terms of bone healing. The mean ulnar shortening reported in the IMF group was small and was not at risk of developing posttraumatic osteoarthritis.

CONCLUSION

IMF is a feasible therapeutic alternative to ORIF for isolated fractures of the distal two-thirds of the ulnar shaft. Further studies with a higher level of evidence need to be conducted to confirm the equivalence of these two fixation techniques.

Delayed Versus Primary Closure of Diaphyseal Forearm Fractures in Adults: Short-Term Soft Tissue Outcomes

INTRODUCTION

The purpose of this study was to investigate the effect of delayed closures, whether delayed primary closure (DPC) or split-thickness skin grafting (STSG), of operatively treated forearm fractures on short-term soft tissue outcomes.

METHODS

In this retrospective cohort comparative study of two academic-level one trauma centers from 2010 to 2020, adult patients with diaphyseal forearm fractures who underwent open reduction and internal fixation (ORIF) were either closed primarily at index surgery, or underwent delayed closure, either with DPC or with a STSG. Primary outcome measures were soft-tissue outcomes as measured by wound healing (delayed healing, dehiscence, or skin breakdown) and fracture-related infection (FRI) at time of final follow-up.

RESULTS

Eighty-one patients with 81 diaphyseal forearm fractures underwent ORIF with a mean follow-up of 14.3 months. Forty-one fractures (50.6%) were open injuries. Thirteen patients (16.0%) were unable to be closed primarily and underwent an average of 2.46 ± 0.7 surgeries including final coverage, with an average of 4.31 ± 2.8 days to final coverage. Four patients (30.8%) underwent DPC and 9 (69.2%) underwent STSG. Five (6.6%) patients in the delayed closure group had pre-operative compartment syndrome and underwent formal two-incision fasciotomies. There were no significant differences between delayed versus primary closure in wound healing complication rates, FRI, or radiographic union.

CONCLUSIONS

Diaphyseal forearm fractures that undergo ORIF have equivalent short-term soft tissue outcomes when closed primarily at index surgery or when closed in a delayed fashion.

American Academy of Orthopaedic Surgeons/American Society for Surgery of the Hand Clinical Practice Guideline Summary Management of Distal Radius Fractures

The Management of Distal Radius Fractures Evidence-Based Clinical Practice Guideline is based on a systematic review of published studies for the treatment of distal radius fractures in adults older than 18 years. The scope of this guideline is limited to the treatment of acute distal radius fractures and does not address distal radius malunion. This guideline contains seven recommendations to assist orthopaedic surgeons and all qualified physicians managing patients with acute distal radius fractures based on the best current available evidence. It serves as an information resource for professional healthcare practitioners and developers of practice guidelines and recommendations. In addition to providing pragmatic practice recommendations, this guideline also highlights gaps in the literature and informs areas for future research and quality measure development.

Induced membrane technique applied to the forearm: Technical refinement, indications and results of 13 cases

INTRODUCTION

The unique anatomical characteristics of the forearm bones makes their reconstruction challenging. The aim of this study was to report the surgical methods and results of the induced membrane technique applied to traumatic forearm bone defects.

MATERIAL AND METHODS

We evaluated retrospectively a case series of 13 patients operated between 2010 and 2017. The first surgical step consisted of debridement of the fracture site and implantation of a cement spacer with appropriate fixation. The anatomy of the forearm skeleton had to be restored. The second step, done 6 weeks later, consisted of removing the cement spacer and applying cancellous bone autograft harvested from the iliac crest. The outcome measures were radiological bone union, need for surgical revision, and postoperative wrist range of motion.

RESULTS

All 13 patients were men, with a mean age of 39 years (18-67). The average follow-up was 2.5 years. Eleven patients were suffering from a nonunion and two from a post-traumatic bone defect. Six patients had an identified preoperative infection. Three patients had previously undergone an unsuccessful treatment for their nonunion with bone addition. The maximum length of bone reconstruction was 12 cm. Union was achieved in 12 of 13 patients in a mean of 5 months (3-8). The other patient died during the postoperative course. Two patients needed revision surgery: ulnar shortening osteotomy (1 case) and additional tendon reconstruction (1 case). The mean pronosupination range was 123° on average (55-180°). The mean flexion-extension range was 106° (90-130°).

CONCLUSION

The induced membrane technique is a reliable reconstruction technique that is well suited to reconstruction of the forearm skeleton.

Wrist fracture management and the role of surgical care practitioner through the patient's journey

The presentation of this case study involves an exploration of the patient's journey in detail after having a traumatic wrist fracture, which is recognised as one of the most common fractures encountered daily in emergency services by junior doctors and practitioners. However, this article not only analyses the medical guidance for this type of case, but also the importance of the surgical care practitioner role in trauma and orthopaedics. All practitioners attending patients in emergency services are required to develop a good knowledge of anatomy, physiology, patient's examination technique, classifications and consequently being aware of the possible surgical options for treatment of the fracture. They will also need to fully understand the legal implications of consent to ensure safe practice.

Fracture nonunion in long bones: A literature review of risk factors and surgical management

Nonunion following a long bone fracture causes considerable morbidity when it occurs. Risk factors depend on specific fractures but there is a complex interplay of injury severity, comorbidities, patient medication and infection. The majority of nonunions occur after long bone fractures with the tibia, femur, forearm, humerus and clavicle predominating. Despite interest in the biological augmentation of fracture healing, the majority of nonunions can be effectively managed with conventional surgical techniques. In this review we present a review of risk factors for nonunion and the outcome following surgical management.
