The infection of Mycoplasma hominis after total knee replacement: Case report and literature review.

The Mycoplasma hominis infection is a rare postoperative complication after joint replacement. Based on our knowledge, there were only two cases reported by Korea all over the world currently. A case of postoperative Mycoplasma hominis infection after total knee replacement in our hospital was reported in this article.

Comparison of interface contact profiles of a new minimum contact locking compression plate and the limited contact dynamic compression plate.

In this study, we investigated whether or not a new minimum contact locking compression plate (MC-LCP) can provide advantages over the limited contact dynamic compression plate (LC-DCP) in the context of interface contact area and force. Six matched pairs of cadaveric bones were used for each of three bone types of the humerus, radius and ulna. For each bone type, one of two bone plates was fixed to either of two matched cadaveric bones at the middle of the diaphysis.

[The comparative study of patients with severe polytrauma treated by damage control orthopedits in normal time and in earthquake].

Objective: To compare the outcome of damage control in patients with severe polytrauma in normal time and in the earthquake of 2008 Sichuan China.

Methods: In the retrospective study, 26 cases with severity polytrauma in peacetime and 24 cases with severe polytrauma who have mainly sustained in the earthquake of 2008 Sichuan China were involovd. The patients' demographics, the methods and effects of damage control were evaluated.

Damage control orthopaedics in 53 cases of severe polytrauma who have mainly sustained orthopaedic trauma.

Objective: To discuss damage control orthopaedics in 53 cases of severe polytrauma who have mainly sustained orthopaedic trauma.

Methods: The data of 53 cases of severe polytrauma who had mainly sustained orthopaedic trauma were retrospectively analyzed. And the methods and timing of damage control orthopaedics were discussed in this study.

Damage control of multiple injuries headed by cervical spinal cord injury.

Objective: To explore the strategy of damage control in clinical treatment of multiple injuries headed by cervical spinal cord injury.

Methods: A retrospective analysis was performed in 32 patients. Cervical fractures associated with tetraplegia occurred in 18 patients, traumatic intervertebral disk hernia associated with tetraplegia in 2 patients, and cervical fractures and dislocation associated with tetraplegia in 12 patients.

Application of injury severity score to multiple injuries headed by spinal cord injury.

Objective: To evaluate the application of injury severity score ( ISS) to multiple injuries headed by spinal cord injury.

Methods: The data of 55 cases (40 males and 15 females, aged 17-69 years, mean equal to 41 years) of multiple injuries headed by spinal cord injury treated in our hospital from January 2000 to December 2004 were reviewed and analyzed with ISS (Version of AIS-2005) to explore their relationship.

Results: The ISS values increased with the number of injured regions, so did the complications.

Primary total hip arthroplasty for acetabular fracture.

Objective: To explore the operative indications and operative methods of primary total hip arthroplasty for acetabular fracture and to observe the clinical curative effect.

Methods: We retrospectively summarized and analyzed the traumatic conditions, fracture types, complications, operative time, operative techniques, and short term curative effect of 11 patients (10 males and 1 female, with a mean age of 42.4 years) with acetabular fracture who underwent primary total hip arthroplasty.

Surgical treatment of infected arterial injuries of the major limb.

Objective: To analyze retrospectively the surgical treatment of 21 cases of infected arterial injuries of the major limb hospitalized from 1989 to 2003 in our department.

Methods: After a radical debridement and drainage, an autologous vessel bypass reconstruction, simple vessel ligation or amputation were carried out respectively according to each patient's condition. In order to make a better milieu for the grafts, local musculo-cutaneous flaps were translocated to cover the wounds in 9 cases.
