The importance of the posteromedial fragment and its specific pinning in fractures of the distal radius.

In fractures of the lower end of the radius, the presence of a posteromedial fragment should be recognized if present. This fragment with two articular surfaces, if not reduced, will damage the radiocarpal and inferior radioulnar articulations. The diagnosis needs to be made on 3/4 X-ray views, as the fracture is often mistaken for a Colles' fracture. The author advises reduction and fixation by a method of double pinning. By comparing two sets of statistics, the overall results are shown to be improved without more complications.

Predicting palmar radio-carpal ligament disruption in fractures of the distal articular surface of the radius involving the palmar cortex.

12 adult cadaver wrists were dissected to identify the regions of origin of the four palmar radio-carpal ligaments. A non-dimensionalized value, called the radio-carpal ligament ratio (RLR), was defined as the width of ligament origin from the radius divided by the length of the capitate. Both values were measured directly from radiographs of the cadaver specimens. The RLRs for the four palmar radio-carpal ligaments were found to be statistically consistent. We applied the RLR concept retrospectively to 20 wrists with intraarticular distal radius fractures requiring open reduction. It was found that those fracture patterns in which the fracture fragment ratios (FFR: widths of the fracture fragments divided by the length of the capitate) were outside the limits of corresponding RLRs had clear intra-operative evidence of palmar radio-carpal ligament disruption, while those with FFRs within the limits of corresponding RLRs were noted to have no ligament disruption.

Corrective osteotomy of the distal radius after fracture to restore the function of wrist joint, forearm, and hand.

Eighty-two patients suffering from a severe deformity of the distal radius were operated on in the course of the past 7 years. The corrective osteotomy was done by implanting a corticocancellous bone graft to restore the correct angle of the joint surface and the correct length of the radius. In addition to this, a buttress T-plate was used, which could be removed 6 months later. In 80% of the cases the results with regard to the function of the patients' hands were good. The operative technique is standardized. It is possible to perform this kind of operation on patients of any age, and the procedure can check Sudeck's atrophy. When the obvious disability of the forearm is corrected the mobility of the wrist joint is simultaneously improved.

Delayed rupture of the thumb extensor tendon. A 5-year study of 18 consecutive cases.

18 consecutive cases of delayed rupture of the extensor pollicis longus tendon were recorded during 5 years; 4 were spontaneous, and 14 after distal radius fracture, most of which were undisplaced or only slightly displaced. 15 cases were operated upon with tendon transfers: 13 had extensor indicis proprius transfer, 1 transfer of the extensor carpi radialis longus, and 1 reoperated with the extensor communis to the little finger as a motor unit. Subjectively, nearly complete satisfaction was reported; all patients were able to elevate the thumb to the level of the palm and full independent index finger movements were noted. In this 5-year-period 4,400 patients with distal radius fractures were treated, giving an incidence of delayed tendon rupture after distal radius fracture of 0.3 percent.

Loss and recovery of trabecular bone in the distal radius following fracture--immobilization of the upper limb in children.

Computed tomography of the human radius is performed using a special purpose scanning device which incorporates a radionuclide (125I) as radiation source. Parameters decribing the trabecular bone and the compact bone are determined at a distal and a diaphyseal measuring site respectively. Using this measurement technique changes in bone mineralization in the radius were studied in a group of 23 children following immobilization of an upper limb for fracture healing. An immobilization period of between three to six weeks resulted in a reduction of the relevant parameter value of up to 44% (mean 16%) in the distal part of the radius, whereas no significant change could be seen in the diaphyseal part of the same bone. Rapid remineralization of trabecular bone is indicated by the increase of the corresponding parameter value at a rate of up to several percent per week. However, in some of the patients studied complete normalization was not attained during the first six months following cast removal.

[Inline skating, an old sport, newly discovered: harmless or a potential danger with socioeconomic effects?].

Over a period of one year, all accidents associated with in-line skating (ILS) were surveyed. Sport-specific data was recorded with a standardized questionnaire. The study comprised 66 patients with 75 injuries (48 upper limb, 16 skull, eight lower limb, three trunk). We were looking after 42 male and 24 female patients with an average age of 20 years (5-53 years). Twenty-seven patients (40%) had to be treated as inpatients. Overall, the most frequent injury (one third of all injuries) was forearm fracture close to the wrist (21 radius fractures, four radioulnar fractures). It had to be reset in 20 cases. Additional internal fixation was required in 10 cases (Kirschner wire osteosynthesis, intramedullary nailing or plate osteosynthesis). Only five patients could be treated with plaster cast fixation alone. Most patients with injuries in the vicinity of the wrist were not wearing a wrist protector at the time of the accident. The most frequent reasons given for not wearing protectors was forgetfulness or the high price of protectors. However, there were also two distal radius fractures and a disc injury in the wrist in patients who had been wearing wrist protectors. In most cases, ILS accidents lead to appreciable damage requiring a healing period of several weeks to months (average period of loss of work 41 days). The bfu (advisory center for accident prevention) reckons with 60,000 ILS cases annually in Switzerland. These injuries are thus of great socioeconomic importance. In the future, better risk behavior must be achieved by informing the population (wearing protectors, especially for the wrist and head, attendance of training courses).

Fractures of the distal end of radius in elderly patients: a comparative study of anatomical and functional results.

The functional and anatomical results of distal end of radius fractures with severe displacement in 22 elderly patients are reviewed in this retrospective study. The mean age of the patients was 69.4 years (range, 60-88 years) and the mean follow-up period was 24 months (range, 12-53 months). According to the sum of demerit points (Saito, 1983), the latest follow-up functional end results were excellent in 64% of fractures and good in 36%. As for the anatomical results at follow-up, the average radial tilt was 20.7 degrees, ulnar variance was 4.0 mm, and palmar tilt was -2.7 degrees respectively. Though most of the patients had satisfactory outcome and the functional results did not correlate with the radiographic evidence of minor deformities, the functional results of the patients with radial shortening of 6 mm or over were poor. Furthermore, the grip power was the most significant factor related to subjective evaluation and did not improve significantly in patients with the non-dominant hand injured.

Complications after Pi Plate osteosynthesis.

BACKGROUND: Distal intraarticular radius fractures can be operated on by means of a palmar or dorsal approach. The dorsal approach has been reported as a treatment option that often leads to tendon ruptures. The purpose of this study was to show that a dorsal implant does not lead to a high rate of tendon ruptures. METHODS: A retrospective study was conducted in which the patient population was analyzed for complaints and complications, follow-up time, and further surgical procedures. RESULTS: A series of 389 patients with distal intraarticular fractures of the radius treated with the dorsal Pi Plate is reported. There was a complication rate of 6.7 percent within the first 2 postoperative months. A special focus was on the occurrence of extensor tendon ruptures, which occurred in five cases in the patient population. This most feared complication occurred within the first 8 months after surgery and in no case at a later stage. All tendon ruptures were reconstructed and healed without further complications. Hardware was removed in 75.5 percent of patients after 6 to 8 months. In the remaining 24.5 percent of patients, the plates were left in situ for more than 33 months, and 89 percent of these patients were free of pain and had excellent movement in the wrist. CONCLUSIONS: The authors conclude that the Pi Plate is a very good surgical option, especially in complicated, comminuted fractures classified as C3. It is not associated with an overly high risk of extensor tendon ruptures, as has been suggested by other authors.
