The objective of this retrospective study was to correlate the Bado and Jupiter classifications with long-term results after operative treatment of Monteggia fractures in adults and to determine prognostic factors for functional outcome. Of 63 adult patients who sustained a Monteggia fracture in a ten-year period, 47 were available for follow-up after a mean time of 8.4 years (5 to 14). According to the Broberg and Morrey elbow scale, 22 patients (47%) had excellent, 12 (26%) good, nine (19%) fair and four (8%) poor results at the last follow-up. A total of 12 patients (26%) needed a second operation within 12 months of the initial operation. The mean Broberg and Morrey score was 87.2 (45 to 100) and the mean DASH score was 17.4 (0 to 70). There was a significant correlation between the two scores (p = 0.01). The following factors were found to be correlated with a poor clinical outcome: Bado type II fracture, Jupiter type IIa fracture, fracture of the radial head, coronoid fracture, and complications requiring further surgery. Bado type II Monteggia fractures, and within this group, Jupiter type IIa fractures, are frequently associated with fractures of the radial head and the coronoid process, and should be considered as negative prognostic factors for functional long-term outcome. Patients with these types of fracture should be informed about the potential risk of functional deficits and the possible need for further surgery

Four men who presented with chronic dislocation of the radial head and nonunion or malunion of the ulna were reviewed after open reduction of the radial head and internal fixation of the ulna in attempted overcorrection. Their mean age was 37 years (28 to 46) and the mean interval between injury and reconstruction was nine months (4 to 18). The mean follow-up was 24 months (15 to 36). One patient who had undergone secondary excision of the radial head was also followed up for comparison. The three patients who had followed the treatment protocol had nearly normal flexion, extension and supination and only very occasional pain. All had considerable loss of pronation which did not affect patient satisfaction. Preservation of the radial head in chronic adult Monteggia fractures appears to be a promising mode of treatment

Background. Chronic acquired radial head dislocations pose a complex problem in terms of surgical decision making, especially if surgery has already previously failed. There are several underlying causes that should be investigated, including previous trauma resulting in a missed Monteggia fracture. Aim. To review the clinical and radiological outcomes for children up to 18 years of age, with a radial head dislocation treated with circular frame surgery. Method. A retrospective study was designed to identify patients from our departmental database who had undergone circular frame surgery to reduce the radial head during the past 6 years. Results. 20 patients were identified with a mean age of 11 years (3 – 17). Fourteen patients had a diagnosis of missed Monteggia fracture, three patients had Hereditary Multiple Exostoses, one had Nail Patella syndrome, one had Osteogenesis Imperfecta and one had rickets. The average delay between trauma and frame surgery was three years (0 – 7). All patients achieved union of their ulnar or radial osteotomy. The average frame duration was 167 days (61 – 325) and complications included delayed union and residual radial head subluxation. Thirteen patients achieved at least 40 degrees of supination, and 10 patients achieved at least 40 degrees of pronation. Eighteen patients achieved an arc of movement from full extension to at least 110 degrees of flexion. Eleven patients reported their pain level at final follow-up, of which 9 had no pain at all. Conclusion and Discussion. Circular frame surgery was a reliable and consistent method of reducing chronic radial head dislocations and improving function. Radiological appearances of mild residual subluxation of the radial head were clinically well tolerated and generally required no further treatment

Introduction. Chronic radial head dislocation in children after trauma is a serious condition. Often the dislocation is overseen initially and is a part of the Monteggia fracture complex with anterior bowing of the ulna. Typical complaints are pain, decreased ROM and cubitus valgus. Radial head dysplasia often occurs. The treatment of this condition is debated. Only few series of patients treated with open reduction and ulnar osteotomy exists with long-term follow up. We present a group of rare patients with long-time follow-up treated by only two surgeons through a period of 16 years. Materials and Methods. All 16 patients had anterior radial head dislocation (Bado type 1). Mean age at the time of traumatic dislocation was 6 years ranging from 2 to 9. We found a mean delay of 17 (range 1–83) months before open reduction and ulnar open wedge osteotomy. In 8 cases reconstruction of the annular ligament was performed and in 6 patients temporary transarticular fixation of the radial head with a k-wire was performed. Follow-up time was 8 (range 3–17) years postoperatively. Patients were investigated with bilateral x-ray, arthrosis status, congruency of the radiocapitellar joint, Oxford Elbow Score, force measurements and range of motion. Results. There were no major complications to surgery such as infection, nerve palsies or pseudarthrosis. Radiological results showed 9/16 with reduction of the radial head and with no arthrosis, 4/16 with arthrosis or subluxation, and 2/16 with a dislocated radial head. We found a significant correlation between radiological outcome and delay to ulnar osteotomy (p = 0.03). At follow up the mean Function score was 92 (SD 9), Social/psychological score 83 (SD 14) and Pain score was 88 (SD 15). None of the patients with fully reduced radial head had progressed in increased valgus deformity. In contrast, one of two patients with postoperative secondary dislocation of the radial head had an increase in carrying angle on 25 degrees. Typical clinical findings were a small but significant extension deficit and median loss of supination on 10 grades ranging from 0–90 (p = 0.008). Five patients had subsequent surgery, of which one had an excision of the radial head 8 years after primary surgery. Ligament reconstruction or transfixation of the radial head did not influence the radiological or clinical outcome. Discussion and Conclusion. Case reports of similar patients treated conservatively demonstrate high morbidity and therefore open reduction and ulnar osteotomy is justified given the good clinical longterm outcome in the present study. However, this study underlines the importance of minimising the delay between trauma and open reduction. If surgery is performed before 40 months after trauma good to fair longterm radiological results can be obtained. After 40 months there is a high risk of recurrent luxation of the radial head

Aims

Heterotopic ossification (HO) is a common complication after elbow trauma and can cause severe upper limb disability. Although multiple prognostic factors have been reported to be associated with the development of post-traumatic HO, no model has yet been able to combine these predictors more succinctly to convey prognostic information and medical measures to patients. Therefore, this study aimed to identify prognostic factors leading to the formation of HO after surgery for elbow trauma, and to establish and validate a nomogram to predict the probability of HO formation in such particular injuries.

The Essex-Lopresti injury is rare. It consists of fracture of the head of the radius, rupture of the interosseous membrane and disruption of the distal radioulnar joint. The injury is often missed because attention is directed towards the fracture of the head of the radius. We present a series of 12 patients with a mean age of 44.9 years (26 to 54), 11 of whom were treated surgically at a mean of 4.6 months (1 to 16) after injury and the other after 18 years. They were followed up for a mean of 29.2 months (2 to 69). Ten patients had additional injuries to the forearm or wrist, which made diagnosis more difficult. Replacement of the head of the radius was carried out in ten patients and the Sauve-Kapandji procedure in three. Patients were assessed using standard outcome scores. The mean post-operative Disabilities of the Arm, Shoulder and Hand score was 55 (37 to 83), the mean Morrey Elbow Performance score was 72.2 (39 to 92) and the mean Mayo wrist score was 61.3 (35 to 80). The mean grip strength was 68.5% (39.6% to 91.3%) of the unaffected wrist.

Most of the patients (10 of 12) were satisfied with their operation and in 11 the pain was relieved. When treating the chronic Essex-Lopresti injury, we recommend accurate realignment of the radius and ulna and replacement of the head of the radius. If this fails a Sauve-Kapandji procedure to arthrodese the distal radioulnar joint should be undertaken to stabilise the forearm while maintaining mobility.

A total of 11 patients with combined traumatic injuries of the brachial plexus and spinal cord were reviewed retrospectively. Brachial plexus paralysis in such dual injuries tends to be diagnosed and treated late and the prognosis is usually poor. The associated injuries, which were all on the same side as the plexus lesion, were to the head (nine cases), shoulder girdle (five), thorax (nine) and upper limb (seven). These other injuries were responsible for the delayed diagnosis of brachial plexus paralysis and the poor prognosis was probably because of the delay in starting treatment and the severity of the associated injuries. When such injuries are detected in patients with spinal cord trauma, it is important to consider the possibility of involvement of the brachial plexus.
