[Treatment of Steroid-induced Osteonecrosis of Femoral Head by Porous Tantalum Rod and Gugutou Huaisiyu Capsule].

Objective: To observe the curative effect of porous tantalum rod and Gugutou Huaisiyu Capsule (GHC) for steroid-induced osteonecrosis of femoral head (SONFH).

Methods: A total 60 hips of 50 SONFH patients were randomly assigned to the treatment group and the control group according to grouping time, 25 in each group (30 hips). Patients in the control group were implanted with porous tantalum rod, while those in the treatment group additionally took GHC (5 pills each time, three time per day for 2 successive months; and then twice per day for 4 successive months).

Sartorius muscle-pedicle bone graft for osteonecrosis of the femoral head.

Purpose: This study summarises the clinical efficacy of sartorius muscle-pedicle bone graft in osteonecrosis of the femoral head.

Methods: A total of 58 patients, including 53 men (61 hips) and five women (6 hips) with osteonecrosis of the femoral head, underwent sartorius muscle-pedicle bone grafting. Association Research Circulation Osseous (ARCO) staging was performed.

[Classification of upper sacral segment based on continuous axial pelvic computed tomography scan].

Objectives: To introduce a classification system of upper sacral segment and its significance based on the continuous pelvic axial computed tomography scan.

Methods: The whole pelvis 2.0 mm thick axial scan images of 127 cases were observed, the sacroiliac screw channel of S1 were measured, according to the size of the transverse screw channel the upper sacral segment were classified.

[Influence of the included angle between anterior aspects of S2 and S1 vertebral bodies on pelvic inlet imaging in mid-line sagittal plane].

Objective: To analyze the influence of included angle between the anterior aspects of S2 and S vertebral bodies on pelvic inlet imaging in the pelvic midline sagittal plane.

Methods: Totally 58 axial pelvic CT scans were chosen as study objects including 43 males and 15 females,with an average age of 40.7 years old (ranged,18 to 68 years old).

[Application of auto-control micro-motion intramedullary locking nail in the treatment of femoral shaft fractures].

Objective: The auto-control micro-motion intramedullary locking nail (AMLN) is designed, to reduce the incidence of delayed union and non-union of femoral shaft fractures fixed by interlocking intramedullary nails, and to observe the clinical effect of self-design AMLN in the treatment of femoral shaft fractures.

Methods: The distal and promixal nails were connected by the micro-motion locking structure, which could cause 1.0-1.

[Multicentre study on treatment of unstable tibiofibular fracture with percutem clamp therapy].

Objective: To objectively evaluate the clinical efficacy, safety and technical operating standard of percutem clamp fixation (PCCF), an operation designed by imitating bone setting method of TCM, in treating unstable tibiofibular fracture (UTF).

Methods: A prospective controlled multicentre clinical study was carried out on 200 patients with UTF, they were assigned to the treated group (99 cases) treated with PCCF and the control group (101 cases) treated with unilateral multifunctional external fixator (UMFEF).

Results: PCCF showed better effects than UMFEF in reducing the time of fixing operation and healing time; and the immediate effect after removing the fixating apparatus and long-term efficacy as well as safety in the treated group were also superior to those in the control group (P < 0.
