Determining scaphoid waist fracture union by conventional radiographic examination: an analysis of reliability and validity.
Conventional radiographic imaging is the first imaging tool of choice in scaphoid fractures. The majority of undisplaced scaphoid waist fractures unite after 6 weeks of cast immobilization. We hypothesized that conventional radiographic imaging at 6 weeks after injury can both accurately and reliably predict union in undisplaced scaphoid waist fractures. ⋯ Conventional radiographic imaging is accurate and moderately reliable in diagnosing union, and reliable but inaccurate in diagnosing nonunion of scaphoid waist fractures at 6 weeks follow-up.

Low preoperative Constant score is a negative predictive factor for postoperative proprioception after total shoulder arthroplasty in osteoarthritis.
Shoulder proprioception in patients with glenohumeral osteoarthritis and the effect of total shoulder arthroplasty (TSA) on proprioception have been evaluated previously. Measuring proprioception with an active angle reproduction (AAR) test, proprioception remained unchanged or deteriorated in a short follow-up period after shoulder replacement. Therefore, the purpose of this prospective study was to evaluate the influence of the preoperative Constant score (CS) on postoperative proprioceptive outcome after TSA in patients with primary osteoarthritis to address the question of whether the preoperative state of shoulder function influences postoperative proprioceptive outcome. ⋯ In conclusion, a low preoperative CS is a negative predictive factor for postoperative proprioception after TSA. We should keep that in mind when determining the best timepoint for shoulder replacement in patients with glenohumeral osteoarthritis.

Open reduction and internal fixation of Ideberg IV and V glenoid intra-articular fractures through a Judet approach: a retrospective analysis of 11 cases.
To evaluate the methods and the outcomes of complex intra-articular glenoid fractures, treated by open reduction and internal fixations. ⋯ Good outcomes could be obtained when Ideberg IV and V glenoid fractures were treated by open reduction and internal fixation through a Judet approach.

Breakage of cephalomedullary nailing in operative treatment of trochanteric and subtrochanteric femoral fractures.
Mechanical breakage of cephalomedullary nail osteosynthesis is a rare complication attributed to delayed fracture union or nonunion. This study presents a series of cases of breakage and secondary lag screw dislocation after cephalomedullary nailing. The aim of this study was to identify factors that contribute to cephalomedullary nail breakage. ⋯ Breakage of cephalomedullary nail osteosynthesis of trochanteric fractures is a severe complication. The results of our study demonstrate that revision surgery provides good clinical and radiological short-term results. Predominately, failures of trochanteric fractures are related to lack of surgeon performance. Therefore, application of the implant requires accurate preoperative planning, advanced surgical experience to evaluate the patient and the fracture classification, and precise surgical technique including attention to detail and anatomical reduction of the fracture fragments.

Minimal invasive posterior total hip arthroplasty: are 6 weeks of hip precautions really necessary?
Postoperative hip dislocations have been reported in 0.5 to 10.6 % of patients after primary posterolateral total hip arthroplasty (THA). Hip precautions are currently recommended for 6 weeks postoperatively to reduce early dislocation and facilitate healing of the posterior soft tissue repair. ⋯ Shortening the time of posterolateral hip precautions from 6 to 4 weeks after surgery does not increase the risk of postoperative dislocation.
