Comparative Study
Comparison of four different reduction methods for anterior dislocation of the shoulder.
Shoulder dislocations account for almost 50% of all major joint dislocations and are mainly anterior. ⋯ We suggest that the Chair method is an effective and fast reduction maneuver that may be an alternative for the treatment of anterior shoulder dislocations. Further prospective studies with larger sample size are needed to compare safety of different reduction techniques.

The regeneration of articular hyaline cartilage remains an elusive goal despite years of research. Recently, an aragonite-hyaluronate (Ar-HA) biphasic scaffold has been described capable of cartilage regeneration over a 6-month follow-up period. This study was conducted in order to assess the fate of the regenerated osteochondral tissue in a 12-month-long validated caprine model. ⋯ Osteochondral defects are common in humans; the results of the current study suggest that an acellular Ar-HA scaffold might induce cartilage and subchondral bone regeneration.

Acetabular revision arthroplasty with major bone loss is one of the most difficult operations in orthopedic surgery. The goal of the study was to evaluate midterm clinical results of the use of morselized allografts with cemented cage support in revision total hip replacement. ⋯ These data confirm that acetabular reconstruction using morselized allografts and cemented acetabular cages is effective in the midterm as a treatment for acetabular loosening with massive bone deficiency.

Comparative Study
Comparison of posterior correction results between Marfan syndrome scoliosis and adolescent idiopathic scoliosis-a retrospective case-series study.
The X-ray films of the patients with Marfan syndrome scoliosis (MSS) look like those with adolescent idiopathic scoliosis (AIS). In literature, there are many reports on the correction results of AIS, while there are a few studies focused on the difference of the correction results between MSS and AIS. This study aims to analyze whether there are differences of posterior correction surgery in MSS and AIS. ⋯ When performing posterior correction for scoliosis, the surgeons should be aware that the patients with Marfan syndrome scoliosis had more estimated blood loss and longer operation duration than AIS patients, while the correction rate was similar.

The aim of the study was to evaluate predictors and clinical relevance of heterotopic ossification (HO) in patients treated for acetabular fractures in a tertiary referral centre. ⋯ A very low rate of HO was found compared to the HO rates described in other studies with similar patient cohorts who received prophylaxis. Based on our findings and the current literature, we do not recommend giving prophylaxis against HO to patients after internal fixation of acetabular fractures.
