Comparative Study
Physeal fractures of the distal radius and ulna: long-term prognosis.
The long-term prognosis of injuries to the distal physis of forearm bones, including complications such as radioulnar length discrepancy and styloid nonunion, has not been extensively studied. Reliable radiographic prognostic criteria to predict physeal disturbance at trauma are also lacking. The aim of this study is to investigate both issues. ⋯ None of the patients reviewed at follow-up, including those with radioulnar length discrepancy of less than 1 cm and those with styloid nonunion, complained of any symptom related to their previous injury, not even those engaged in heavy manual labor. Of the 10 patients with either radial or ulnar shortening of more than 1 cm, only 2 with radial growth arrest and marked radioulnar length discrepancy had severe functional problems. Growth disturbances of more than 1 cm following distal radial physeal injury occurred only in Ogden type 1C, 2B, and 2D lesions, whereas in distal ulnar physeal injuries, growth disturbances occurred regardless of the Ogden classification type.

Fractures of the olecranon: a 15- to 25-year followup of 73 patients.
The incidence of olecranon fractures in adults and the long-term outcome of closed olecranon fractures in 45 women and 28 men (mean age, 54 and 36 years at the time of fracture, respectively), were examined at a mean of 19 years after the fracture. The uninjured elbows served as controls. Thirteen percent of the original fractures were displaced less than 2 mm, 65% more than 2 mm, and 22% were multifragmental. ⋯ Radiographic signs of degenerative changes were found in more than 50% of the formerly fractured elbows, which was more than in the uninjured (11%). Radiographic signs of osteoarthritis were found in 6% of the formerly fractured elbows versus zero percent in the uninjured, of which only two patients had a poor outcome. Isolated, closed fractures of the olecranon in adults have a favorable, long-term outcome.

Case Reports Multicenter Study Comparative Study
Supracondylar fractures of the humerus associated with ipsilateral forearm fractures in children: a report of forty-seven cases.
Supracondylar fractures of the humerus associated with ipsilateral forearm fractures are uncommon and treatment recommendations are controversial. The purpose of this study was to determine whether pin fixation of both fracture components, humerus and forearm, would improve the outcome. In a two-center trial, 884 children sustaining supracondylar fractures of the humerus were retrospectively reviewed, and 47 (5.3%) showed associated ipsilateral forearm fractures. ⋯ There were no reangulations in the patients who had pin fixation of their fractures. There were no complications due to pin fixation in the humerus or the forearm. In unstable supracondylar humerus and forearm fractures, stabilization with pin fixation to prevent reangulation should be considered.

The treatment of isolated ulnar fractures remains controversial, with different authors recommending both surgical and non-surgical management. We undertook a systematic review of the current literature in order to assess whether any conclusions can be drawn. A total of 33 series involving 1876 patients were identified as suitable for analysis. ⋯ However, these have not been verified in clinical studies. Compression plate fixation gave reliable results in these cases. Other methods lacked sufficient published data to be recommended.

Comparative Study
Biomechanical comparison for different configurations of tension band wiring techniques in treating an olecranon fracture.
The aim of this study was to compare the superiority between the newly designed modified AO tension band wiring technique and the traditional modified AO tension band wiring technique in treating an olecranon fracture. ⋯ The new technique may be applied widely to treat all olecranon fractures, because it is a technically easier and safer technique. Less than 5.5-kg loads could be permitted in daily activity postoperatively. A single tolerable loading weight should not exceed 8 kg. Kirschner wires will not migrate proximally, despite increased joint loading. Clinically, this study may confirm indirectly the hypothesis that proximal migration of Kirschner wires was mainly due to triceps traction.
