Wrist malalignment, in cases of malunited fractures of the distal radius, is not always a consequence of adaptation of the wrist to new conditions, but an expression of non-diagnosed ligamentous injuries. The aim of our study is to examine if the wrist malalignment is correctable with radius osteotomy.

Twenty nine patients (17 female, 12 male) of mean age 51 years, with symptomatic malunited fracture of the distal radius with dorsal angulation, of duration 3 months -47 years, were examined. Twenty seven patients underwent corrective radius osteotomy (open dorsally in 26 cases and closed palmarly in 1 case). Fixation material (plate and screws) was placed on the dorsal side in 23 cases and on the volar side in 4 cases. In all patients measurements on the lateral X-ray view, concerning the reversal of the normal palmar tilt of the radius, the radiolunate and lunocapitate angles, were performed before and after surgery. Based on those measurements patients were divided in two groups:

a) In group A (23 patients) the malalignment concerned the midcarpal joint, and

b) In group B (6 patients) the malalignment concerned the radiocarpal joint.

The radiographic element of evaluation was the radiolunate angle. Radiolunate angle greater than 25° indicated malalignment at the radiocarpal level while radiolunate angle less than 25° indicated malalignment at the mid-carpal level. In 5 patients post-operative measurements were not performed because in addition to the radial osteotomy they were subjected to operative correction of wrist malalignment.

Results estimated immediately postoperative and at the final follow-up, 6 months later. In patients with midcarpal malalignment, correction was possible, under the condition of a sufficient radius osteotomy and a non fixed midcarpal deformity. In patients with radiocarpal malalignment the deformity persisted despite the correction of the radial osteotomy.

We conclude that correction of wrist malalignment is not always achieved with corrective osteotomy of the radius and that preoperative radiological control may be indicative of the possibility of correcting the deformity.

Fracture of the volar rim of the distal radius could be an isolated fracture or part of a complex type of fracture. Frequently it is displaced and rotated because of the attachment of the volar radio-carpal ligaments. Fixation of this fragment is mandatory to preserve integrity of radio-carpal and distal radio-ulnar joints. Given the difficulty of manipulation of this osteochondral fragment we studied the efficiency of a wire-loop as a method of fixation of this fragment.

Eleven patients were examined (8 male, 3 female) mean age 42,6 years (21–72 years) who had various type of fractures of the distal radius but had in common the presence of an osteochondral fracture of the volar radial rim in the ulnar side (7 patients), in the radial side (3 patients) or on both sides (1 patient). Distal radius fracture was type B3.1 (1 patient), B3.3 (4 patients), C3.1 (3 patients), C1.3 (1 patient) and radiocarpal fracture-dislocation in 2 cases. All patients were treated operatively. Eight of them had early (1 – 10 days post-injury) and three had delayed treatment (1 month post-injury). The rim fragment was found displaced in all patients and rotated 45°-180° in 5 patients. Different types of fixation of the distal radius fractures were used, while in all patients the rim fragment was fixed using a wire loop.

Results were estimated after a mean follow-up of 1 year (6 months- 4 years) using clinical (pain, function, range of motion, grip strength) (Cooney 1987) and radiological (articular congruence, arthritis) criteria. Results were evaluated as excellent (4 patients), good (5 patients) fair (1 patient) and poor (1 patient), while in two cases there was loss of fragment reduction.

In conclusion, although intraarticular fractures are often associated with injury of the interosseous ligaments, probably they have no effect on the integrity of the volar radiocarpal ligaments, the origins of which could influence the volar rim fracture displacement. Wire loop is a valid method for fixation of osteochondral fracture of the volar radial rim, giving stability and avoiding comminution and necrosis of the fragment.

It is known that the delayed diagnosis of Essex-Lopresti injury can lead to devastating results concerning the function of the upper extremity. The aim of our study is to suggest methods of early diagnosis and treatment based on our experience on ten patients who were treated for this rare injury.

We studied 10 patients (9 male and 1 female), average 36,5 years old (25–53) who sustained comminuted fracture of the radial head, isolated (3 patients) or with concomitant injury of the ipsilateral (3 patients) or the contralateral upper extremity (4 patients). Initially, 8 patients were treated with excision and 2 with internal fixation of the radial head and radioulnar transfixing pin. Gradually, they all developed subluxation of the DRUJ and they were treated for established Essex-Lopresti injury, 1–7 months after initial injury. Six patients were treated with reduction of radioulnar length (ulnar shortening osteotomy, with or without distraction with an external fixator) and TFC suturing. In 4 patients the radial head was replaced with a metallic implant, joint levelling and TFC suturing.

The results were estimated after an average follow-up of 67 months (1–10 years) based on radiological (radioulnar equivalence) and clinical criteria (wrist and elbow range of motion, forearm rotation and grip strength). Excellent results were achieved in 4 patients who underwent metallic radial head replacement. Conversely, in the rest patients the radioulnar discrepancy relapsed in various degrees but the radiological result does not correlate with the clinical picture.

We concluded that early diagnosis is necessary but not the only prerequisite for a good long-term result. Replacement of the radial head with titanium implant, offers good result at least in the short and mid-term period.
