Nonunion of the distal radius is a rare complication (0.2%) which gradually can lead to deformity, pain and dysfunction of the hand. We examined 7 patients who developed nonunion of the distal radius after surgical intervention and we try to rationalize this complication.

Our material consisted of 7 patients (2 male and 5 female) average 51 years old (31–75). Two patients with distal radial malunion, developed nonunion after corrective osteotomy. Four patients with comminuted metaphyseal radial fracture and concomitant distal ulna fracture, developed nonunion after application of an external fixator alone or in combination with internal fixation. Finally one patient with isolated fracture of the distal metaphysis developed nonunion after internal fixation. All patients after the confirmation of the nonunion and until radiological union underwent 1–3 operations. The index procedures for final union were wrist arthrodesis (1 patient) radioscapholunate fusion with excision of the distal scaphoid (2 patients) and internal fixation (4 patients). Additionally, in 6 patients a supplementary method for DRUJ asymmetry was needed.

Results were estimated after a mean follow-up of 30,8 months (1–4 years) based on radiological and clinical criteria. There were 1 excellent, 5 good and 1 fair result.

Despite the existence of predisposing factors (comminution, associated fracture of the distal ulna, metabolic disease, osteoporosis, distraction through external fixator), the contribution of the surgeon to the development of the nonunion is undeniable.

Introduction: The combined fractures of the clavicle (or A-C dislocation) and the scapular neck are complex injuries related to high energy trauma. Their management varies depending on the degree of instability and the presence of neurovascular complications. We evaluated the results of the treatment given to this rare injury.

Material and Method: During a five year period (1997–2001) we treated 12 patients with floating shoulder. The injury was in all cases the result of severe road traffic accident. Nine patients were males and three females with age ranging from 20 to 51 years. Seven patients had injured the right shoulder, the remaining five having injured the left one. Eight patients had additional injuries (chest in four, head in two, fracture of the T4 with complete paraplegia in one, chest and abdominal in one).

Three patients had neurovascular complications and were operated upon. Two of them with vascular injury were operated ungently and had arterial graft and stabilization of the clavicle or the A-C joint with tension band. The third patient with only neurological injury (axillary and suprascapular nerves) had similar stabilization of his clavicle. The remaining nine patients with minor displacement of the fractures and stable shoulder girdle were managed conservatively.

Results: We reexamined eleven patients. The mean follow-up period was 19 months (8–56 months). In nine patients-including the three operated-the fractures had healed in satisfactory position. In the remaining two the fracture of the scapular neck was malunited, resulting in loss of shoulder normal configuration and restriction of shoulder elevation. In two of the operated patients the coexistence of neurological injury resulted in poor functional outcome. The third one-with the axillary and suprascapular nerve injury-improved in relation to the axillary nerve within six months from the injury and had a fairly useful upper extremity. In the Constant-Murley scale the score ranged from 28–89 points (average 67 points).

Conclusion: In conclusion, fractures of the clavicle (or A-C dislocations) and the scapular neck are injuries of high energy and are usually encountered in multiplez injured patients. Severe displacement is usually related to instability of the shoulder girdle and neurovascular injuries; urgent operation is then necessary and the final result is often poor. In cases of severe displacement the stabilization of only the clavicle is not sufficient and open reduction and internal fixation of the scapular neck is recommended.

Introduction: Internal fixation of distal radius fractures with dorsal plates (when needed) comprise two potential problems: efficacy of stabilization and the high frequency of tendonitis which forced us to early removal of the hardware. Our purpose is to study the efficacy of the method of stabilization with 2 plates (2mm) the central and radial columns of distal radius according to the technique presented by Regazzoni (1993).

Material and Methods: Eight patients (5 males and 3 females), average 35 years old (range, 20–52 years) were treated with comminuted intraarticular fracture type C (6 patients) or malunion of distal radius (2 patients). A combined approach was used in 4 patients and only dorsal approach in the rest 4 patients. In all patients with recent comminuted fractures a supplementary fixation method with allograft were used. In patients with mal-united fractures the technique with two plates together with iliac graft were applied.

Results: Results estimated after mean follow-up of 14 months (range 9–18 months) according to clinical (pain, range of motion, and grip strength) and radiological (articular congruency, radial height, radial inclination and palmar tilt) criteria. Six patients revealed excellent or good result although two patients with loss of reduction needed a second operation.

Conclusion: We concluded, that when the technique with 2 plates was applied correctly the stability of fixation enhanced because the detrimental rotational forces were cancelled while the frequency of tendon irritation decreased.
