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

METHODSAfter 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.

RESULTS1 case (4.8%) died during the treatment. 5 cases (5/21, 23.8%) underwent amputations. Blood supply reconstruction was successful in 15 cases (15/21, 71.4%). 93.3% (14/15) of the cases were successful in getting an unobstructed vessel at early stage. Thrombosis occurred in 1 case (1/15, 6.7%) and a sound result was obtained after a second operation.

CONCLUSIONSRadical debridement combined with bypass vessel reconstruction with autologous vein and with musculo-cutaneous flap translocation is an effective treatment for infective limb vascular injuries.

Objective To retrospectively study revisions for infected total hip replacements in 30 cases and discuss the bacteriological characters of the infected total hip replacements,difficulties and strategies in the revision.Methods Thirty revisions of infected total hip replacements were reviewed retrospectively.There were 12 males and 18 females,with mean age of 62.5 years(31-86 years)at revi- sion surgery.Infection was presented one month to four years(mean seven months)after THA operation. The diseases for initial operation included femoral neck fractures in 12 cases,femoral head necrosis in 11,hip osteoarthritis in five and rheumatoid arthritis in two.Twelve eases were treated by one-stage revi- sion and 18 by two-stage revision.Results Before the revision operation,the hip infection were diag- nosed by bacterial culture in 18 cases including five with Staphylococcus epidermidis,four with Staphylo- coccus aureus and nine with other bacteria.Bacteria growth appeared on the specimens from 23 hip joints during the revision surgery but not on the specimens from seven hip joints.Of 12 one-stage revisions,10 cases were followed for mean 16 months,which showed infection recurrence in two eases.Of 18 two-stage revisions,13 cases were followed for mean 20 months,which showed one case with infection recurrence. The mean Harris hip score was improved from preoperative 44 to 84 at follow-up.Conclusions 1) The main bacteria in the infected hip are antibiotic resistant Staphylococcus.2)Because the revision op- eration is difficult,careful preparation before revision is important for success.The fresh surgeon should not attempt.3)The revision strategies should vary according to specific status of the cases.The infection recurrence rate is lower when using a two-stage revision strategy.4)Application of antibiotic bone cement can help improve treatment effect and facilitate functional recovery of the joints.5)The scientific rehabil- itation after operation is very important to functional recovery.

Objective To report the experience of the application of microsurgery in joint replace- ment.Methods There were 22 cases,10 cases with segmental acetabular defects treated with the pedicle sartorius muscle iliac bone grafting,5 cases with vascular repair following major vascular injury of extremity during operation,6 cases with neural repair following neural injury during operation,1 case with serious injury reconstruction by elbow joint replacement and free flap.Results The operations succeeded in 22 cases without any postoperative infection.The mean follow-up was 40.1 months (3-72 months) in 22 cases,in which the joint function improved and the operative result was satisfactory with no joint pain.Conclusion Microsurgical technique can reconstruct bone and tissue defect effectively in joint replacement.

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

METHODSThe 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.

RESULTSWe succeeded in rescuing the lives of all the 53 patients, and 38 patients returned to their former work.

CONCLUSIONSInjury Severity Score (ISS(90)) should be 17 in severe polytrauma patients, but in severe polytrauma patients who have mainly sustained orthopaedic trauma, the ISS(90) of bone and joint injuries should be 16. We recommend that primary minimally-invasive external fracture stabilization should be made for extremities and pelvis in these patients to avoid additional surgical trauma and that definitive secondary fracture care should be performed after medical stabilization for these patients in intensive care unit (ICU).

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

METHODSA 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. Seventeen cases were combined with craniocerebral injury, 7 combined with pulmonary contusion, multi-fractures of rib or hemopneumothorax, 2 combined with pelvic fracture and other 8 combined with fracture of limbs. The neural function was assessed by the American Spinal Injury Association (ASIA) scale.

RESULTSThirty-one patients were followed up for an average of 14 months. Of them, 10 got complete recovery, 13 obtained improvement of more than one ASIA grade, 8 did not improve, and 1 died.

CONCLUSIONSFor the emergency treatment of multiple injuries headed by cervical spinal cord injury, the damage control strategy is the principle to follow. The final operations are preferably performed within 5 to 10 days after injury so as to raise the successful rate of remedy.

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

METHODSIn 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.

RESULTSIn the earthquake group, 24 cases succeeded in the rescuing life; among whom, 3 patients needed the further debridement and dermoplasty. In the normal time group, 26 cases succeeded in the rescuing life; among whom, 19 patients had returned to their former work and 3 patients needed the further treatment. There was no difference between two groups in therapeutic effects (P > 0.05).

CONCLUSIONBoth in earthquake and in normal time, treating the severity polytrauma by damage control orthopedics can acquire satisfied effect.

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

METHODSWe 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.

RESULTSThe patients were followed up for 6-45 months (mean=28 months). Their average Harris score of postoperative hip joint was 78.

CONCLUSIONUnder strict mastery of indications, patients with acetabular fracture may undergo primary total hip arthroplasty, but stable acetabular components should be made.

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

METHODSThe 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.

RESULTSThe ISS values increased with the number of injured regions, so did the complications. The recovery rate was negatively related to ISS values. During the period of immunity observation, the patients with ISS larger than 25 could undergo planned operations safely.

CONCLUSIONSTreatment for multiple injuries headed by spinal cord injury closely depends on the general and local conditions of the patients. ISS may provide useful data for the choice of treatment methods.

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. It was confirmed through mass spectrometer and Mycoplasma cultivation and treated by the first stage debridement, polyethylene insert replacement, and then drainage and irrigation combined with sensitive antibiotics after the operation. We observed that the C reactive protein (CRP) level correlates with the development of disease, while the erythrocyte sedimentation rate (ESR) remains at a high level, indicating the relevance between the Mycoplasma hominis infection caused by knee joint replacement and CRP. This study aims to report the case and review relevant literature.
