Radial Head Fractures

Radial Head Fracture (Mason Type 4) Fixation With Headless Compression Screws: The "Tripod Technique"

Radial head fractures are fairly common fractures in the general population accounting for up to 30% of elbow fractures. The management of these fractures is controversial, specially in the higher grade of fractures. The current case report presents a middle-aged male patient with a fracture dislocation of the radial head in the dominant hand. After undergoing adequate investigations, the fracture was classified and managed with headless compression screws using the tripod technique. The management of the patient, preoperative planning, and the complications faced are mentioned in the current report. The patient on follow-up shows a good range of motion and an improved Mayo elbow score. Thus, stating good results can be obtained in Mason type 4 fractures using osteosynthesis with headless compression screws.

Anatomic Monopolar Press-fit Radial Head Arthroplasty; High Rate of Loosening at Mid-Term Follow Up

Introduction

Radial head arthroplasty (RHA) is used for the management of unstable or unreconstructable injuries of the radial head. Our aim was to investigate clinical and radiographic outcomes in patients treated with the Acumed anatomic radial head press-fit system for trauma.

Methods

Clinical and radiographic assessment of RHAs undertaken for trauma with minimum 2-year follow-up.

Results

16 consecutive patients, mean age 53 (21-82) and 66 month ± 27 (26-122) clinical follow-up were included. There were marked radiographic changes with 11/16 showing periprosthetic lucent lines and 13/16 showing subcollar osteolysis. Radiographic changes occurred early post-surgery. Stem loosening was associated with larger cantilever quotients (0.47 vs 0.38, p  =  0.004). Overall survivability was 81.2%, with 3 RHAs removed. Clinical outcomes for the retained RHAs were acceptable with mean flexion 134°, extension deficit of 10°, pronation of 82°, and supination of 73°. Mean VAS scores were 8.5 ±  14.4, QuickDASH 13.8 ±  18.9, Mayo Elbow Performance Scores were 91.5 ±  12.5 with no poor scores.

Conclusion

Mid-term clinical functional outcomes following the Acumed anatomic RHA are acceptable in most cases. However, in view of the extensive periprosthetic lucencies and surgical removal due to loosening, patients should be cautioned when consented for implantation of the prosthesis, especially if a large collar is anticipated.

The Emergent Evaluation and Treatment of Elbow and Forearm Injuries

This article provides an updated review of the emergent evalution and treatment of elbow and forearm injuries in the emergency department. Clinically necessary imaging is discussed. Common and uncommon injuries of the elbow and forearm are reviewed with an emphasis on early recognition, efficient management, and avoidance of complications. The astute emergency physician will rely on a focused history and precise examination, applied anatomic knowledge, and strong radiographic interpretative skills to avoid missed injuries and complications.

Use of surgical glue for Mason type III radial head fractures: A case report

RATIONALE

A Mason type III radial head fracture, which is characterized by comminuted fragments of the radial head, is a severe injury. Open reduction and internal fixation (ORIF) is an alternative treatment method; however, the technique of using an on-table reduction in combination with surgical glue is rarely reported.

PATIENT CONCERNS

A 48-year-old man was admitted to our department with complaints of elbow pain after falling down. Elbow radiography and computed tomography (CT) demonstrated characteristics of fractures before the operation.

DIAGNOSIS

Radiographic images showed a Mason type III radial head fracture.

INTERVENTIONS

The patient underwent ORIF at our hospital. During the operation, the technique of on-table reconstruction combined with surgical glue was used.

OUTCOMES

The patient recovered well and was able to participate in his usual work.

LESSONS

Mason type III radial head fractures could be treated with ORIF, and a satisfactory result could be anticipated, thus avoiding a radial head replacement or resection. Anatomical reduction of a comminuted radial head could be obtained via an on-table reconstruction and application of surgical glue.

[Typical fractures and dislocations of the elbow joint and their treatment]

Diagnosis and treatment of injuries to the elbow joint place high demands on the treating physicians. The complex anatomy of the elbow joint enables a wide range of movement and complex functions in everyday and professional life. These must be restored in the event of injury.Clinical and imaging-based diagnostic procedures serve to classify typical injuries of this joint according to a large variety of different pathologies. These include fractures of the distal humerus, the proximal ulna, and the radial head, as well as dislocations and dislocation fractures.The following article gives an overview of the most common of these injuries.
