Calcium homeostasis influences radiological fracture healing in postmenopausal women.
Recent studies suggest that calcium and 25-[OH]-cholecalciferol represent substantial co-factors in fracture healing. However, there still seems to be no sustainable consensus regarding the influence on fracture healing patterns. In this study, the influence of calcium and vitamin D levels on fracture callus formation was prospectively analysed using pQCT scan. ⋯ Calcium and parathyroid hormone serum levels influence fracture callus area interpreted as fracture callus formation patterns. Calcium levels within physiological range accounted for highest fracture callus area. Therefore, a balanced calcium homeostasis is required for appropriate callus formation.

Intraoperative soft tissue tension and postoperative range of motion in posterior stabilized total knee arthroplasty.
Intraoperative soft tissue tension can significantly impact the range of motion following total knee arthroplasty (TKA). However, the level of impact remains unclear. The purpose of this study was to investigate the relationship between intraoperative soft tissue tension and postoperative range of motion. ⋯ We did not observe a correlation between intraoperative soft tissue tension adjusted from 80 to 160 N and 1-year postoperative range of motion in posterior stabilized TKA.

Open arthrolysis and hinged external fixation for posttraumatic ankylosed elbows.
An ankylosed elbow is defined as an elbow having a range of motion of 0°. Movement is extremely limited. This study retrospectively analyzes the results of arthrolysis and hinged external fixation performed on 15 patients suffering from ankylosed elbows. ⋯ Open arthrolysis and monolateral hinged external fixation are effective in treating posttraumatic ankylosed elbow. Arthrolysis should be performed by a combination of lateral and medial approaches. In addition, routine hinged external fixation and anterior transposition of the ulnar nerve may improve the postoperative recovery of elbow stiffness.

Significance of segmental instability in cervical ossification of the posterior longitudinal ligament and treated by a posterior hybrid technique.
Retrospective cohort case study. ⋯ Segmental instability, a degenerative dynamic factor, is important to the OPLL myelopathy. The posterior hybrid technique seemed to be effective and safe in the treatment of selective OPLL patients associated with SI. The benefits may include providing stabilization environment for spinal cord recovery, and preventing progressive kyphotic change and progression of OPLL.

Randomized Controlled Trial Multicenter Study Comparative StudyOperative vs conservative treatment of traumatic patellar dislocation: results of a prospective randomized controlled clinical trial.
Patellar dislocation is a common knee injury with mainly lateral dislocations, leading to ruptures of the medial patellofemoral ligament in most of the cases. Even though several prognostic factors for patellofemoral instability have been identified so far, the appropriate therapy for patients with patellar dislocation remains a controversial issue. The purpose of this study was to compare the outcome after conservative or operative treatment in patients after first-time patellar dislocation. ⋯ Our multicentric prospective randomized controlled trial revealed no significant difference between conservative and operative treatment for patients after first-time traumatic patellar dislocation. However, a tendency towards a better Kujala score and lower redislocation rates for patients with operative treatment was observed. The small number of patients is a limiting factor of the study, leading to results without statistical significance. A meta-analysis including other study's level I data is desirable for the future.
