Acromioclavicular joint (ACJ) injury is a common shoulder injury. There are various techniques of ACJ reconstruction. Superficial infection after ACJ reconstruction is not an uncommon complication. However, osteomyelitis post ACJ reconstruction has never been highlighted as a possible complication. Our patient is a 31-year-old male who sustained a Rockwood 5 ACJ dislocation and had anatomical ACJ reconstruction with autogenous gracilis and semitendinosus graft. Our technique involved the anatomical reconstruction of the ACJ and the coracoclavicular ligament with the usage of two bioscrews and the temporary stabilisation of the ACJ with two k-wires. As in any orthopaedic surgery, infection is often disastrous especially when the surgery involves implants. It can be disastrous with high morbidity to the patient as well as a costly complication to treat. Therefore, we wish to highlight this case as despite its rarity, osteomyelitis can be devastating to the patient and should be prevented if possible.

BACKGROUND: To prevent risk of life-threatening stent thrombosis, all patients need to undergo dual antiplatelet therapy (DAPT) for at least 6 weeks to 12 months after stent implantation. If DAPT is continued during noncardiac surgery, there is a risk of severe bleeding at the surgical site. Our study was to assess the risk of bleeding in patients with continued DAPT during orthopedic surgery. METHODS: The clinical data of 78 patients with coronary heart disease who underwent orthopedic surgery from February 2006 to July 2018 were retrospectively analyzed. Prior to orthopedic surgery, DAPT was continued in 16 patients (group I), 24 patients were treated with single antiplatelet therapy (group II), and 26 patients received low-molecular-weight heparin therapy for more than 5 days after the discontinuation of all antiplatelet therapies (group III). Twelve patients were excluded, as they had undergone minimally invasive surgery such as transforaminal endoscopy and vertebroplasty. The perioperative blood loss of each patient was calculated using Nadler's formula and Gross' formula. The intraoperative bleeding volume, total volume of intraoperative bleeding in addition to postoperative drainage, and total blood loss were compared between groups. The level of significance was set at P < 0.05. RESULTS: There were no significant differences between the three groups in age, intraoperative bleeding volume, total volume of intraoperative bleeding in addition to postoperative drainage, and total perioperative blood loss calculated by Nadler's formula and Gross' formula (all P > 0.05). Six patients experienced postoperative cardiovascular complications due to the delayed restart of antiplatelet therapy; one of these patients in group III died from myocardial infarction. CONCLUSIONS Continued DAPT or single antiplatelet treatment during orthopedic surgery does not increase the total intraoperative and perioperative bleeding compared with switching from antiplatelet therapy to low-molecular-weight heparin. However, the discontinuation of antiplatelet therapy increases the risk of serious cardiac complications.

To evaluate the efficacy of operative and non-operative treatment for three- or four-part proximal humeral fractures in elderly patients by meta-analysis.The literature search was performed in Cochrance Library, Medline, Embase, SinoMed, CNKI, Wanfang data and CQVIP databases for operative and non-operative treatment of three- or four-part proximal humeral fractures in elderly patients, and searches of conference proceedings were also conducted. The data were extracted and a meta-analysis was performed using RevMan 5.3. The outcome measures included Constants score, pain and incidence rates of AVN, reoperation, osteoarthritis, nonunion.Six randomized controlled trials involving 264 patients were included in the meta-analysis. The differences of Constant scores (=0.47, 95%:-4.35-5.28,=0.85), incidence of ANV (=0.56, 95%:0.25-1.24,=0.15), incidence of osteoarthritis (=0.56, 95%:0.19-1.68,=0.30), incidence of nonunion (=0.43, 95%:0.13-1.43,=0.17) between operative group and non-operative group were not statistically significant. Operative treatment was better in pain score (=1.01, 95%:0.12-1.19,=0.03) and had statistically significant higher reoperative rate (=3.97, 95%:1.45-10.92,=0.007).No evidence support that there is difference in Constant score and incidence rate of ANV, osteoarthritis, nonunion between operative and non-operative treatment for three- or four-part proximal humeral fractures in elderly patients. More high quality randomized controlled trials are required to determine which treatment is more efficient.

Antegrade transmalleolar drilling method is one of the options for the treatment of osteochondral lesion of talus (OLT). We present five patients who underwent tibial drilling for treatment of OLT and later developed distal tibial cystic formation induced by cartilage opening or heat necrosis during drilling. Antegrade transmalleolar drilling can be a possible option for the treatment of OLT if the lesion is not easily reachable; however, other viable treatment should be considered due to its possibility of distal tibial pathologic change.

OBJECTIVETo investigate the therapeutic effect of total en bloc spondylectomy (TES) for thoracolumbar tumors and the results of spinal stability reconstruction.

METHODSFrom January 2007 to June 2011 there were 18 patients with thoracolumbar tumors distributed in the thoracic vertebrae (n = 10) and lumbar vertebrae (n = 8). There were 7 haemangiomas, 5 giant cell tumors of bone, 1 malignant schwannoma, 1 solitary plasmocytoma, 1 neuroblastoma, 1 osteoblastoma, 1 metastatic malignant fibrous histiocytoma, and 1 metastasis of breast cancer. All the 18 patients were treated with improved TES under electrophysiological monitoring of spinal cord. Four patients were treated through one-stage combined anteroposterior approach and 14 patients through one-stage posterior approach. The anterior reconstructions included titanium mesh cages filled with bone or bone cement in 15 cases, titanium mesh cage with strengthened rings in 2 cases and artificial vertebral body replacement in 1 case. The posterior reconstruction included multiple segmental fixation with pedicle screw-rod system in 15 cases and short segmental fixation in 3 cases. Massive bone auto-graft was employed in 13 cases and fragmental bone graft in 5 cases.

RESULTSThe total en bloc spondylectomy was performed successfully in 15 patients and unsuccessful in 3 whose spinal tumors were resected by piecemeal technique. In 15 patients with successfully performed TES, the duration of surgery was from 340 to 610 min (average, 450.7 min), the blood loss was from 3000 to 10 200 ml (average, 4850 ml), and the intraoperative blood transfusion was from 2800 to 9600 ml (average, 4200 ml). The operation-related complications comprised hemopneumothorax, intercostal nerve pain, stress ulcer and bleeding, and so on. One year after operation, the patients with neurological dysfunction recovered from grade A to grade D in one patient, and to grade E in the other 14 cases. The average visual analog scale (VAS) scores was 0.5. One patient with plasmacytoma and another one with L5 metastatic tumor suffered progression of the disease and were living with the diseases. The patient with metastatic malignant fibrous histiocytoma died of local recurrence and lung metastasis 16 months postoperatively. One patient with L4 neuroblastoma died of other reason and all the rest were free from relapse. The Cobb angle of upper and lower vertebral body adjacent to the involved vertebrae in sagittal plane was from -26.7° to 12.0° (average, -2.57°) just postoperatively and from -17.5° to 57.2° (average, 11.5°) at the last follow-up or before reoperation. There were 2 patients with screw-rod breakdown and 2 patients with internal fixation loosening. The measurement of titanium mesh cage subsided into adjacent vertebral bodies was average 7.5 mm. The revision surgery was performed in 3 patients, through combined anteroposterior approach in 2 and only posterior approach in 1 patient.

CONCLUSIONSTES significantly increases the therapeutic effect of spinal tumors, although accompanied with high difficulty and massive bleeding. In spinal stability reconstruction after total spondylectomy, it should be emphasized that posterior long segment fixation with pedicle screw-rod system, massive bone bridging graft and the application of thoracolumbosacral orthosis can achieve short-term firm fixation and long-term fusion-stabilization.

BACKGROUND: Due to the anatomical nature of the radial nerve, dissection and attainment of an adequate operative field in mid to distal humerus fracture is dangerous and limited. We devised a combined anterolateral and lateral approach that ensures protection of the radial nerve. This is achieved by performing bimodal dissection of the proximal humerus anteriorly and the distal humerus laterally. METHODS: Thirty-five consecutive patients were treated using a combined anterolateral and lateral approach for a minimum follow-up period of 24 months. We analyzed time to bony union, time to return to daily work, range of motion, elbow joint function as assessed by the Mayo elbow performance index and complications. RESULTS: Radiologic bony union was observed at 11.2 weeks (range, 8 to 20 weeks) on average. Four cases of incomplete radial nerve palsy before surgery all recovered. Time to return to work was 10.2 weeks (range, 2 to 32 weeks) on average. The average range of motion of the elbow was 3.3degrees (range, 0degrees to 10degrees) of extension and 135.9degrees (range, 125degrees to 145degrees) of flexion. There were 21 cases of excellent and 13 cases of good or better recovery, comprising over 97.1% on the Mayo elbow performance index. There were no complications of radial nerve palsy, non-union, mal-union, or infection. CONCLUSIONS: Our a modified combined anterolateral and lateral approach is a clinically effective surgical method of achieving protection of the radial nerve and securing easy and firm internal fixation.

The two-stage exchange arthroplasty (one- or two-stage) is believed to be the gold standard for the management of infections following total knee arthroplasty. We herein report a novel two-stage exchange arthroplasty technique using an antibiotic-impregnated cement intramedullary nail, which can be easily prepared during surgery using a straight thoracic tube and a Steinmann pin, and may provide additional stability to the knee to maintain normal mechanical axis. In addition, there is less pain between the period of prosthesis removal and subsequent reimplantation. Less soft tissue contracture, less scar adhesion, easy removal of the cement intramedullary nail, and successful infection control are the advantages of this technique.

OBJECTIVETo assess the effect of the anterior surgical approach for thoracolumbar spine tuberculosis and analyzed the causes of the surgical complications and the countermeasures.

METHODSFrom Jan 1996 to Dec 2005, 120 patients with thoracolumbar spine tuberculosis underwent operations through the anterior approach either following the primary diagnosis (115 cases) or for recurrence (5 cases).

RESULTSIntraoperative pleural rupture occurred in 4 cases, and rupture of the external iliac vein occurred 1 case. Three patients had damages of the T12 dorsal ramus. One patient developed venous embolism of the lower extremity after the operation, two had paralytic ileus and 1 had false diabetes insipidus. Of the 5 recurrent patients, 1 died due to alcoholic cirrhosis and acute liver failure, 1 received a third operation for loosened internal fixation, and 1 had recurrence due to extensive drug resistance (XDR).

CONCLUSIONStandardized antituberculous therapy is fundamental for preventing the recurrence of tuberculosis, and individualized antituberculous therapy adjustment according to the results of bacterial culture and drug sensitivity tests can be the most effective means for preventing drug resistance and reducing tuberculosis recurrence.

OBJECTIVE: To investigate the surgical techniques and clinical outcomes of total hip replacement for patients with end-stage osteoarthritis secondary to developmental dysplasia of the hip. METHODS: From May 2004 to March 2008, a total of 36 total hip replacements were performed in 32 patients with end-stage osteoarthritis secondary to developmental dysplasia of the hip. The acetabulum cup was reconstructed in the corresponding anatomical position in all cases. Cemented components were used in 16 hips, and cementless components in the other 20 hips. The mean follow-up was 31.3 months. Clinical outcomes were determined with Harris hip score. Radiographs were taken after the surgery and in every follow-up examination for further reference. RESULTS: All patients postoperatively gained a limb lengthening with an average of (3.4+/-1.3) cm. Three patients had complications, 2 had nondisplaced fractures of the proximal part of the femur,and 1 sciatic nerve palsy which disappeared after 3 months. There was no infection, dislocation and symptomatic deep vein thrombosis. Compared with preoperation, the mean Harris hip scores on the 3rd day, the 14th day after the operation and at the last follow-up were all improved significantly (all P<0.05). There was no loosening, migration, heterotopic ossification radiographically, and no revision during the follow-up. CONCLUSION Total hip replacement is an effective treatment for patients with end-stage osteoarthritis secondary to developmental dysplasia of the hip. The key is to place the acetabulum cup in the corresponding anatomical position, and choose proper prosthesises during the surgery.

OBJECTIVE: To analyze the etiology and prevention of complications related to the pedicle screw technique in the treatment of thoracic scoliosis. METHODS: There were 183 thoracic deformity patients 110 idiopathic scoliosis, 32 adult scoliosis, 28 congenital kyphoscoliosis, 8 Marfan syndrome with scoliosis, and 6 others. All patients' Cobb angles were evaluated preoperatively, intraoperatively, and postoperatively by roentgenograms. The deformity correction rate was calculated. All radiographic evaluations were carried out in a double-blind fashion. The complication rate was analyzed perioperatively and postoperatively. RESULTS: The deformity correction rate was 72%, better than others treated with hook-rod system. The perioperation complication rate was 8.4% (pedicle fracture 1.5%, infection 3.8%, pneumothorax and plural effusion 1.6%, transitory neurological damage 0.5%, and over-bleeding shock 1%). The complication rate at follow-up was 3.6% (infection 0.5%, fatigue fracture 1%, loss of deformity correction 1.6%, and transitory neurological damage 0.5%). Compared with those treated with hook-rod system, the perioperation complication rate, loss of deformity correction, permanent damage, and complications related to the internal fixation were all low. CONCLUSION The complication rate of pedicle screw fixation system was low in the treatment of thoracic deformity. When surgeons are thoroughly familiar with the technique and related pathoanatomy, and with the spinal cord function wardship by SEP, complications related to the pedicle screw technique in the treatment of thoracic scoliosis will be well controlled.
