Inability to actively supinate the forearm makes common activities of daily living and certain vocational activities awkward or impossible to perform. A total of 11 patients with deficient supination of the arm underwent transfer of the tendon of flexor carpi ulnaris to the split tendon of brachioradialis with its bony insertion into the radial styloid left intact. Active supination beyond neutral rotation was a mean of 37.2° (25° to 49.5°) at a minimum follow-up of three years, representing a significant improvement (95% confidence interval 25 to 50, p < 0.001). Functional evaluation of the hand after this transfer showed excellent and good results in ten patients and fair in one. The split tendon of brachioradialis as an insertion for transfer of the flexor carpi ulnaris appears to provide adequate supination of the forearm without altering the available pronation and avoids the domination of wrist extension sometimes associated with transfers of the flexor carpi ulnaris to the radial extensors of the wrist

Malunion of fractures of the forearm in children can lead to permanent disability. The capacity of the radius and ulna to remodel spontaneously after malunion has been assessed in this study. Forty-nine children who had malunited fractures of the forearm were examined when the remodelling process was complete. It was noted that fractures of the distal third of the radius and ulna led to fewer problems than those of the diaphysis. It was concluded that malunion of the distal third of the radius and the ulna will remodel satisfactorily providing the child is less than 14 years of age. Gross malunion of the midshaft of the radius and ulna will spontaneously correct in an infant but little useful correction of deformity can be anticipated in diaphysial fractures when the child is aged eight years or more

Florid reactive periostitis is a pronounced periosteal reaction, usually affecting the hands and feet, for which there is no obvious cause. It is rare in children and in long bones. We report an unusual case of florid reactive periostitis in a ten-year-old girl that involved both bones of the forearm. The lesion resolved over a period of one year, leaving a residual exostosis. She developed a physeal bar in the distal ulna in the region of the lesion at one-year follow-up. This was thought to be a complication of the biopsy procedure and was treated by resection and proximal ulnar lengthening

We identified 25 children (10 girls and 15 boys) who had been treated with single bone intramedullary fixation for diaphyseal fractures of both forearm bones. Their mean age was 10.75 years (4.6 to 15.9). All had a good functional outcome. We conclude that in selected children, single bone intramedullary nailing is a suitable method of treatment for diaphyseal fractures of both bones of the forearm

1. A series of fractures of the forearm has been treated by exceptionally rigid internal fixation with a special plate and screws. 2. The plate and screws are described. 3. The results of rigid fixation are found to be: i) reliability of union, and ii) good final function. 4. The lessons learned regarding the application of the plate and the after-treatment of the forearms are recounted

We studied 55 patients who had undergone elective removal of forearm plates between 1980 and 1986; 44 plates were removed from the radius and 37 from the ulna. Before removal only 20 patients (36%) had definite symptoms attributable to the plates, but 44 patients (80%) were advised by the surgeon to have the plates removed. In 22 cases (40%) the operation was followed by a significant complication. The complication rate was higher with junior surgeons and was permanent in 50% of cases. It is recommended that forearm plates should be removed only if they are causing significant symptoms, and that the operation should not be delegated to the most junior surgeon

We reviewed 36 cases of forearm deformity caused by multiple osteochondromas in 30 patients and classified them into three types: Type I showed a combination of ulnar shortening and bowing of the radius secondary to osteochondromas of the distal ulna (22 forearms). Type II showed dislocation of the radial head, either with osteochondromas of the proximal radius (Type IIa, two forearms) or secondary to more distal involvement (Type IIb, five forearms). Type III had relative radial shortening due to osteochrondromas at the distal radius (seven forearms). Operations were performed on 16 forearms in 13 patients, with 92% of satisfactory results. For Type I deformity, excision of osteochondromas, immediate ulnar lengthening and corrective osteotomy of the radius are recommended. For Type IIa, excision of the radial head is necessary, and for Type IIb, we advise gradual lengthening of the ulna using an external fixator. Excision of osteochondromas alone gave good results in Type III deformity. Our classification gives a reliable indication of the prognosis and is a guide to the choice of surgical treatment

Seven patients with segmental defects of both bones of the forearm had reconstruction operations using a vascularised fibular graft to bridge the radius. Reasonable forearm rotation was preserved with full elbow movements and satisfactory hand function

Fractures of the proximal forearm in young children may be unstable with the elbow flexed but stable with it in extension. Fifteen such fractures were managed by immobilisation in long-arm casts with the elbow extended. Only one patient had more than 15 degrees angulation at the time of bony union. All obtained normal elbow movement at two weeks and full forearm rotation at follow-up. No casts fell off. The extended elbow cast is awkward but it provides an alternative to internal fixation for some unstable fractures

We investigated whether, in the management of stable paediatric fractures of the forearm, flexible casts that can be removed at home are as clinically effective, cost-effective and acceptable to both patient and parent as management using a cast conventionally removed in hospital. A single-centre randomised controlled trial was performed on 317 children with a mean age of 9.3 years (2 to 16). No significant differences were seen in the change in Childhood Health Assessment Questionnaire index score (p = 0.10) or EuroQol 5-Dimensions domain scores between the two groups one week after removal of the cast or the absolute scores at six months. There was a significantly lower overall median treatment cost in the group whose casts were removed at home (£150.88 (. sem. 1.90) vs £251.62 (. sem. 2.68); p <  0.001). No difference was seen in satisfaction between the two groups (p = 0.48). Cite this article: Bone Joint J 2013;95-B:1714–20

In children with obstetric brachial plexus palsy (OBPP) who develop an internal rotation deformity of the shoulder, release of subscapularis improves the range of external rotation of the shoulder and the strength of supination of the forearm. We studied the strength of supination in 35 healthy adult volunteers at 45° of both internal and external rotation. The mean and maximum torques were greater in external than internal rotation by 8.7% and 7.5%, respectively. This was highly significant (p < 0.0001). The increased strength of supination in external rotation is probably because the maximum power of biceps, particularly the long head, may be exerted in this position. In children the difference may be even greater due to anatomical differences causing the dramatic increases in the strength of supination after surgery for OBPP. In adults our findings suggest that the supination exercises which are undertaken after injury or surgery to the forearm or wrist should be performed in external rotation

We treated 22 children with a supracondylar fracture of the humerus and an ipsilateral fracture of the forearm by closed reduction and percutaneous fixation. There were four Gartland type-II and 18 Gartland type-III supracondylar fractures of the humerus. There were fractures of both bones of the forearm in 16 and of the radius in six. Both the supracondylar and the distal forearm fractures were treated by closed reduction and percutaneous fixation. The mean follow-up time was 38.6 months. At the latest follow-up there were 21 excellent or good results and one fair result. There were no cases of delayed union, nonunion or malunion. Five nerve injuries were diagnosed on admission and all recovered spontaneously within eight weeks. No patient developed a compartment syndrome

Displaced fractures of the forearm in children are often treated conservatively, but there is a relatively high incidence of redisplacement, malunion and consequent limitation of function. We have performed percutaneous Kirschner (K) wire fixation in 72 such children under the age of 14 years, of which 57 were reviewed for our study. Both the radius and ulna were fractured in 45 (79%), the radius only in eight and the ulna only in four. The mean initial angulation was 19° in the lateral plane and 9° in the anteroposterior plane for the radius and 15° and 9°, respectively, for the ulna. In 42 patients (74%) we performed closed reduction. In the remaining 15 (26%) closed reduction failed and an open reduction, through a minimal approach, was required before K wiring. At a mean follow-up of 20 months all patients had good functional results with an excellent range of movement. Only five had angulation of from 10° to 15° and none had nonunion, premature epiphyseal closure or deep infection. Percutaneous intramedullary K wiring for forearm diaphyseal fracture is a convenient, effective and safe operation, with minimal complications

Aims

The aims of this study were to identify means to quantify coronal plane displacement associated with distal radius fractures (DRFs), and to understand their relationship to radial inclination (RI).

1. The problem of gap defects in the forearm bones and its solution by radio-ulnar fusion is discussed. 2. Seven patients with radio-ulnar fusions are presented. In four patients the operation was done for defects in the ulna, in two for defects in the radius, and in one for non-union of the radius and ulna after fracture. 3. The good cosmetic and functional result after radio-ulnar fusion is emphasised

1. The posterior interosseous nerve of the forearm is vulnerable to constriction in an aponeurotic cleft in the supinator muscle. 2. A case is presented of paresis of the nerve by an intramuscular lipoma which extended into this cleft. 3. A discussion is given of the possible relation of this feature to certain cases of occupational stress–"tennis elbow.". 4. An approach is described for decompressing the nerve in the rare cases which do not respond to conservative treatment

We report two cases of bilateral chronic exertional compartment syndrome (CCS) in the forearmand hand. Measurement of the intramuscular pressure was useful for diagnosis. These two cases illustrate that bilateral CCS should be suspected in patients complaining of bilateral exercise-induced pain in the anconeus muscle, the forearms, the thenar and hypothenar regions and in the first dorsal interosseous muscle. Fasciotomy relieved the pain in both cases

Aims. Torus fractures of the distal radius are the most common fractures in children. The NICE non-complex fracture guidelines recently concluded that bandaging was probably the optimal treatment for these injuries. However, across the UK current treatment varies widely due to a lack of evidence underpinning the guidelines. The Forearm Fracture Recovery in Children Evaluation (FORCE) trial evaluates the effect of a soft bandage and immediate discharge compared with rigid immobilization. Methods. FORCE is a multicentre, parallel group randomized controlled equivalence trial. The primary outcome is the Wong-Baker FACES pain score at three days after randomization and the primary analysis of this outcome will use a multivariate linear regression model to compare the two groups. Secondary outcomes are measured at one and seven days, and three and six-weeks post-randomization and include the Patient Reported Outcome Measurement Information System (PROMIS) upper extremity limb score, EuroQoL EQ-5D-Y, analgesia use, school absence, complications, and healthcare resource use. The planned statistical and health economic analyses for this trial are described here. The FORCE trial protocol has been published separately. Conclusion. This paper provides details of the planned analyses for this trial, and will reduce the risks of outcome reporting bias and data driven results. Cite this article: Bone Joint Open 2020;1-6:205–213

The incidence of refracture following the removal of screws and plates from the diaphyses of 115 forearm bones in 80 patients has been studied. Refracture occurred in four adult patients as a result of minimal trauma, in two patients at the original fracture site after premature plate removal, at the site of a countersunk interfragmentary screw in one and at the original fracture site in another who had required three operative procedures to achieve 'union'. It is suggested that refracture could have been avoided in at least two of these patients. If the 3.5 mm plating system has been used, the incidence of refracture should be minimal

1. A technique for bridging bone defects in the forearm with massive iliac graft and medullary nailing is described. 2. The results of fifteen operations are reviewed
