The challenge of the surgical treatment of paediatric distal radius/ forearm fracture: K wire vs plate fixation - outcomes assessment.

Aim Distal radius/forearm fractures in adolescent patients remain challenging injuries to treat. Distal radius/forearm bony anatomy is not completely restored with intramedullary K wire fixation. The aim of this study was to compare radiographic and functional outcomes obtained using intramedullary K wire fixation and open reduction and internal fixation in the treatment of distal radius/ forearm fracture. Methods A total of 43 patients who presented with distal radius/ forearm fractures were enrolled and divided into two groups: 23 patients treated with K-wire (IMNK) and 20 patients treated with plate and screws (ORIF). The evaluation criteria were: fracture healing time, objective quality of life measured by the Mayo wrist score (MWS) and quick disabilities of the arm, shoulder and hand score (QuickDash), length time of surgery, complications, sport or play return, forearm visual analogic pain (FVAS), bone healing by radius union scoring system (RUSS). Results In both groups the results obtained were comparable in terms of functional, pain and return to play/sport after the third month after surgery. Bone healing was faster in IMNK than ORIF but without significance (p>0.05). There was less complication in ORIF than IMNK (p<0.05). Conclusion The treatment of adolescent distal radius or forearm fractures remains challenging. One challenge facing the physician is the choice of surgical technique and fixation method, which will be influenced by individual experience and preference. The question of distal radius or forearm fractures in adolescents would be best answered with a prospective randomized study.

Hybrid external fixation in the treatment of tibial pilon fractures: A retrospective analysis of 162 fractures.

OBJECTIVES: To determine the efficacy of hybrid external fixation in the treatment of tibial pilon fractures. DESIGN: Retrospective, multicentre study. PATIENTS/PARTICIPANTS: Adult patients with tibial pilon fractures treated with hybrid external fixation. INTERVENTION: Fracture reduction with ligamentotaxis and fixation with XCaliber hybrid external fixator. MAIN OUTCOME MEASUREMENTS: Fracture union, complications, functional outcome (Mazur Ankle Score). RESULTS: Union was obtained in 159 fractures at an average of 125days; there were three delayed unions and three non-unions. The most frequent complication was superficial pin-track infections (48), all of which responded to local wound care and antibiotics. There were no deep infections and no DVT. Only one fracture had loss of reduction that required frame revision. The overall functional scores were 91 (excellent) for AO/OTA type A fractures, 89 (good) for type B fractures, and 75 (satisfactory) for type C fractures. CONCLUSIONS: Hybrid external fixation is an effective method of stabilising tibial pilon fractures, particularly those with marked comminution. The minimally-invasive technique and stable fixation enable early mobilisation, with good functional results and minimal complications. LEVEL OF EVIDENCE: Level IV Case series.

Comparison among total knee arthroplasties with a mobile bearing: menisci versus rotating platform versus AP glide platform.

A retrospective study was conducted on 60 patients (53 females, seven males with a mean age of 68 years and 5 months) who underwent a total knee replacement using a mobile bearing. The diagnosis was primary osteoarthritis in 57 cases and rheumatoid arthritis in three cases. None of the patients underwent a bilateral procedure, thus 60 implants (33 all cementless, three all cemented, 24 with only the tibial component cemented) were considered. Three different groups were identified: Group 1: first 20 total knee arthroplasties with menisci. Group 2: first 20 total knee arthroplasties with rotating platform. Group 3: first 20 total knee arthroplasties with AP glide platform. Clinical and radiological results at the final follow up, although different in time among the three groups, have shown no revision due to mechanical or septic reasons, and no signs of impending failure.

On a case of multifocal osteonecrosis in a patient suffering from acute lymphoblastic leukemia.

The Authors describe the case of a 14-year-old girl who developed a multifocal osteonecrosis (ON), after treatment with chemotherapy and corticosteroids for acute lymphoblastic leukemia (ALL). She came to our attention about 6 months after the beginning of treatment complaining of pain in her left knee and later in both hips and shoulders. Radiography and MRI confirmed the presence of avascular ON at all these sites. The patient underwent bilateral total hip arthroplasty, which was still functioning well at the last follow-up visits at 5 years, and at 5 years and 4 months. ON is increasingly recognized as a complication of the treatment of cancer in children and adolescents, and as patients now frequently survive ALL into adulthood, orthopedists will be increasingly called on to manage this complication affecting multiple joints in children and young adults.
