Patient-reported outcome assessment after total joint replacement: comparison of questionnaire completion times on paper and tablet computer.
Patient-reported outcome (PRO) assessment is becoming increasingly important after joint replacement surgery. However, PRO data collection, questionnaire handling, and data processing are time consuming and costly process. The aim of our study was to evaluate the efficiency of PRO assessment using tablet computers compared with traditional paper questionnaires in a total hip or knee arthroplasty (THR or TKR) population. ⋯ Electronic PRO data collection can substantially decrease time, logistics, and effort associated with questionnaire completion in daily clinical practice. It is also acceptable for use in an older arthroplasty population.

Titanium-nickel shape memory alloy (Ti-Ni SMA) is characterized by shape-memory effect, super-elasticity, excellent fatigue behavior, corrosion resistance, acceptable biocompatibility and high damping capacity. ⋯ The Ti-Ni SMA-claw fixator produced good osteosynthesis effect by continuous recovery stress with relatively simple and minimally invasive handling process, which can be introduced as an alternative to traditional tension band technique for treatment of patellar transverse fracture.

Cast-treated distal radius fractures: a prospective cohort study of radiological outcomes and their association with impaired calcaneal bone mineral density.
We hypothesized that treating distal radius fractures with cast only or closed reduction and cast is associated with high malunion risk and that the risk is higher in patients with low bone mineral density (BMD). ⋯ Closed reduction and cast is not an effective treatment for distal radius fractures if radiological graphic outcomes are considered. There is a higher risk of malunion involving dorsal and radial tilt in patients with osteoporosis. Calcaneal BMD measurement may have some benefit in predicting the risk of severe malunion.

Comparative StudyReconstruction techniques in comparison for reverse shoulder trauma prosthesis in the elderly: a follow-up between 2 and 4 years.
The aim of this study was to evaluate the clinical outcome of a bone graft technique called bCAT (bone Collar And Tie), in which the fractured humeral head is modelled into a collar shape versus puzzle piece reconstruction (PPR) in elderly patients with complex proximal humeral fractures. ⋯ The PPR and the bCAT techniques promoted the healing and correct positioning of the tuberosities thereby resulting in good functioning of the residual cuff. The bCAT technique resulted in better clinical function particularly in abduction and extrarotation and in terms of radiological outcome of reverse prosthesis surgery.

Displaced supracondylar humeral fractures: influence of delay of surgery on the incidence of open reduction, complications and outcome.
Closed reduction and pinning is the accepted treatment choice for dislocated supracondylar humeral fractures in children (SCHF). Rates of open reduction, complications and outcome are reported to be dependent on delay of surgery. We investigated whether delay of surgery had influence on the incidence of open reduction, complications and outcome of surgical treatment of SCHFs in the authors' institution. ⋯ III (retrospective comparative study).
