There is an increasing trend towards radial head replacement (RHR) or fixation for complex radial head fractures. These injuries are identified by grossly displaced fragments or elbow instability. The aim of this study was to examine the outcome of a surgical protocol that emphasised delayed radial-head excision (RHE) as the procedure of choice. When the humero-ulnar joint was congruent, intervention was delayed 10 to 14 days to allow time for ligamentous healing. RHR was performed if instability was demonstrated on-table. A retrospective study was performed to identify the outcome of patients undergoing surgery for a radial head fracture between 2008 and 2014. There were 18 Mason Type III and 18 Mason Type IV injuries. There was an associated coronoid fracture in 17 patients. RHE was performed in 28 patients, of which the reoperation rate was 2 (7.1%). RHR was performed in 15 patients, of whom 4 (27%) had reintervention. RHR was most common in the Type III coronoid fractures. The cumulative reoperation rate was 9.3% at six months and 15.4% at two years. The median Oxford Elbow Score (OES) was 85.4 (IQR 73.4 to 99.5). Time from injury was the only predictor of the Oxford Elbow Score (p=0.04). This surgical protocol resulted in a reduced need for RHR, a low reintervention rate, and satisfactory function. RHR should be reserved for cases where stability cannot be achieved on-table. Stability can be maximised by delaying RHE until early ligamentous healing occurs

A total of 14 women and seven men with a mean age of 43 years (18 to 68) who sustained a Mason type IV fracture of the elbow, without an additional type II or III coronoid fracture, were evaluated after a mean of 21 years (14 to 46). Primary treatment included closed elbow reduction followed by immobilisation in a plaster in all cases, with an additional excision of the radial head in 11, partial resection in two and suturing of the annular ligament in two. Delayed radial head excision was performed in two patients and an ulnar nerve transposition in one. The uninjured elbows served as controls. Nine patients had no symptoms, 11 reported slight impairment, and one severe impairment of the elbow. Elbow flexion was impaired by a mean of 3° (. sd. 4) and extension by a mean of 9° (. sd. 4) (p < 0.01). None experienced chronic elbow instability or recurrent dislocation. There were more degenerative changes in the formerly injured elbows, but none had developed a reduction in joint space. We conclude that most patients with a Mason type IV fracture of the elbow report a good long-term outcome

The Essex-Lopresti injury (ELI) of the forearm is a rare and serious condition which is often overlooked, leading to a poor outcome.

The purpose of this retrospective case study was to establish whether early surgery can give good medium-term results.

From a group of 295 patients with a fracture of the radial head, 12 patients were diagnosed with ELI on MRI which confirmed injury to the interosseous membrane (IOM) and ligament (IOL). They were treated by reduction and temporary Kirschner (K)-wire stabilisation of the distal radioulnar joint (DRUJ). In addition, eight patients had a radial head replacement, and two a radial head reconstruction.

All patients were examined clinically and radiologically 59 months (25 to 90) after surgery when the mean Mayo Modified Wrist Score (MMWS) was 88.4 (78 to 94), the mean Mayo Elbow Performance Scores (MEPS) 86.7 (77 to 95) and the mean disabilities of arm, shoulder and hand (DASH) score 20.5 (16 to 31): all of these indicate a good outcome.

In case of a high index of suspicion for ELI in patients with a radial head fracture, we recommend the following: confirmation of IOM and IOL injury with an early MRI scan; early surgery with reduction and temporary K-wire stabilisation of the DRUJ; preservation of the radial head if at all possible or replacement if not, and functional bracing in supination. This will increase the prospect of a good result, and avoid the complications of a missed diagnosis and the difficulties of late treatment.
