Simple posterior elbow dislocations are often being treated with strict immobilization after reduction. We performed a study in order to investigate if a functional protocol of rehabilitation, allowing early motion, would be more effective.

We prospectively followed twenty five consecutive patients for simple posterior elbow dislocation in a non-randomized study. Patients were divided in two groups. Group A (twelve cases) was treated with immobilization using a cast in 90 degrees of flexion and neutral rotation for three weeks. Group B (thirteen cases) was treated according to a functional rehabilitation program that allowed early controlled mobilization starting on the 2nd post-traumatic day, consisting of immediate flexion from 90° and gradual extension after the 2nd week. Follow-up of the patients was recorded at six weeks and three months. The functional scores used were Mayo Clinic Performance Index, Liverpool Elbow score and Broberg and Morey.

None of the patients had an incident of redislocation. Patients of group B had statistically significant better (p< 0.05) functional scores at six weeks and better no statistically significant in three months: group B/group A: Mayo: 91.6/65.5, Liverpool: 8.8/6.1, Broberg and Morey: 89.1/73.3.

It seems that a functional rehabilitation program gives the same result in terms of stability offering at the same time patients a better range of motion and functional score at least at six weeks and three months.

Aims: The objective of our study is to elucidate the chondrogenic potential of free autologous periosteal grafts in treating articular cartilage defects, especially in complicated cases where apart from the cartilage defect there are coexisting lesions. Methods: 60 young rabbits were randomly divided in 5 groups. A cartilage defect 0.5 ⋄ 0.5 was created in both knees of each rabbit and covered with free autologous periosteal graft. In the right knee an additional ligamentous lesion was created. Results: All the knees were amputated at one, two and three months postoperatively. Apart from the histological examination, the cartilage specimens were tested biomechanically. An indentation test was used using a Shore A sclerometer and the data were evaluated and compared. In the test group the produced fibrocartilage or hyaline-like cartilage, was mechanically inferior (hardness 50–70 GPa) comparing to the control knees group (98 GPa). The results were statistically evaluated (using O’Driscoll’s histological grading scale and Wilcoxon rank sum test). Conclusions: Autologous periosteal transplantation can be used in daily practise, as it is a method relatively easy to perform with low cost and without any contra-indications. Nevertheless, in cases of unstable knees the method has poor results and ligamentous repair is recommended first.

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.

Aim : We investigated the combination of closed reduction, percutaneous osteosynthesis with screws and external fixation in the treatment of high-energy fractures of the tibial condyles with severe soft-tissue lesions.

Method : We studied 35 fractures (11 open) of the tibial condyles. Twenty-eight were Schatzker type VI, 5 type V and 2 type I. The fracture was reduced under fluoroscopic control and the articular surface was fixed with cannulated lag screws. In 23 patients (group A) a unilateral external fixation was applied with the proximal pins placed in the tibial condyles. In 12 patients (group B) an external fixation crossing the knee was used for 6 weeks followed by a knee brace. The follow-up period was 8–45 months

Results: All fractures united in a mean time of 15 weeks except for two in group A that needed conversion to internal fixation. Ten knees developed pintract infection. All knees had range of motion of at least 1000 except for one in group B that developed osteoarththritis. A collapse of the articular surface of more than 5mm and malalignment of more than 60 were observed in 7 and 5 patients in group A and B respectively.

Conclusions: Limited internal and external fixation are a satisfactory technique for selected fractures of the tibial plateau, particularly with poor soft-tissue envelope. Crossing the knee with the external fixator does not necessarily lead to significant stiffness.

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.
