Objective. To analyze the effect of PFNA-II internal fixation on hip joint recovery and quality of life (QOL) in patients with lateral-wall dangerous type of intertrochanteric fracture. Methods. One hundred and twelve patients with lateral-wall dangerous type of intertrochanteric fracture who underwent surgical treatment in our hospital from May 2017 to May 2019 were selected as the participants of the study. Based on the treatment method, all the enrolled patients were divided into two groups: proximal femoral nail antirotation (PFNA group; n = 59 ) who received closed reduction and minimally invasive PFNA internal fixation and dynamic hip screw group (DHS; n = 53 ) who received internal fixation. The clinical indicators, curative effect, hip function score, pain degree, postoperative QOL score, and complications were compared between the two groups. Results. The operation time, intraoperative blood loss, postoperative drainage volume, and the incidence of postoperative complications in PFNA group were statistically lower than those in DHS group ( P < 0.05 ). The curative effect in PFNA group was notably better than that in DHS group. There were no significant differences in scores of hip function, visual analogue scale (VAS), and QOL between the two groups before operation ( P > 0.05 ). However, the hip function score and QOL score increased in both groups after surgery, and the increase was more significant in the PFNA group, while the VAS score decreased in both groups, and the decrease in PFNA group was more significant ( P < 0.05 ). Conclusion. PFNA internal fixation for the treatment of lateral-wall dangerous type of intertrochanteric fracture has the advantages of short operation time, less intraoperative blood loss, effective improvement of hip joint function, and fewer postoperative complications, which is worthy of clinical application.

Avascular necrosis of the femoral head is a complex medical and social problem. The rapid development of the disease, the complexity of diagnosis and the prevalence among young patients leads to impaired hip joint function and further disability. To improve the quality of life of patients, the Orthopedic Department of the Traumatology Center of Khabarovsk developed a method of minimally invasive two-stage decompression. Surgical treatment was performed in 30 cases in patients with ANFH of stages 0, 1, 2 (by ARCO). Evaluation of treatment results was carried out before operative treatment, after 6 and 12 months. 12 months after surgical treatment, positive dynamics was noted, namely, pain reduction, a walking distance increase, abandonment of crutches, opportunity to use public transport, ability to sit for a long time in one and the same position, to put on shoes, and the abandonment of constant intake of non-steroidal anti-inflammatory drugs. The assessment of hip joint function in 20% of cases showed an excellent result, in 26,6% of cases — a good result, in 40% — satisfactory, and in 13,3% (4 people) — unsatisfactory result, which proves the effectiveness of the proposed treatment method and the feasibility of its use.

Sector Angle

A new set of angles measured on standard axial CT images of the hip joint is defined. The angles provide information on the support of the femoral head from the anterior and the posterior part of the acetabulum. These angles have been measured in 82 adult hips, and correlated to a set of established parameters commonly measured at conventional roentgenography and on CT images of the hip joint. The defined angles may prove to be valuable in the total appreciation of hip joint function and stability.

AbstractAvascular necrosis of the femoral head (ANFH) is a debilitating bone disease, characterized by collapse of the femoral head and subsequent loss of hip joint function. Heterozygous mutations in COL2A1 have been identified to cause familial ANFH. Here we report on a large Chinese family with ANFH and a novel heterozygous mutation (c.3517 G > A, p.Gly1173Ser) in exon 50 of COL2A1 in the Gly-X–Y domain. Previously, only five different COL2A1 mutations have been described in patients with familial ANFH. Therefore, our findings provide significant clues to the phenotype–genotype relationships in familial ANFH and may be helpful in clinical diagnosis. Furthermore, these results should assist further studies of the mechanisms underlying collagen diseases.

Abstract Avascular necrosis of the femoral head (ANFH) is a debilitating bone disease, characterized by collapse of the femoral head and subsequent loss of hip joint function. Heterozygous mutations in COL2A1 have been identified to cause familiar ANFH. Here we report on a large Chinese family with ANFH and a novel heterozygous mutation (c.3517 G > A, Gly1173Ser) in exon 50 of COL2A1 in the Gly-X-Y domain. Previously, only five different COL2A1 mutations have been described in patients familiar ANFH. Therefore, our findings provide significant clues to the phenotype-genotype relationships in familiar ANFH and may be helpful in clinical diagnosis. Furthermore, these results should assist further studies of the mechanisms underlying collagen diseases.

Abrasive Flow Finishing

Total hip arthroplasty (THA) is one of the most well-known orthopedic surgeries in the world which involves the substitution of the natural hip joint by prostheses. In this process, the surface roughness of the femoral head plays a pivotal role in the performance of hip joint implants. In this regard, the nano-finishing of the femoral head of the hip joint implants to achieve a uniform surface roughness with the lowest standard deviation is a major challenge in the conventional and advanced finishing processes. In the present study, the inverse replica fixture technique was used for automatic finishing in the abrasive flow finishing (AFF) process. For this aim, an experimental setup of the AFF process was designed and fabricated. After the tests, experimental data were modeled and optimized to achieve the minimum surface roughness in the ASTM F138 (SS 316L) femoral head of the hip joint through the use of response surface methodology (RSM). The results confirmed uniform surface roughness up to the range of 0.0203 µm with a minimum standard deviation of 0.00224 for the femoral head. Moreover, the spherical shape deviation of the femoral head was achieved in the range of 7 µm. The RSM results showed a 99.71% improvement in the femoral head surface roughness (0.0007) µm under the optimized condition involving the extrusion pressure of 9.10 MPa, the number of finishing cycles of 95, and SiC abrasive mesh number of 1000.
