Surgical treatment of complete thoracolumbar fracture and dislocation / 中华创伤杂志

Objective To investigate the methods and effects of posterior fixation and fusion in treatment of complete thoracolumbar fracture and dislocation.Methods The study enrolled 8 cases of complete thoracolumbar fracture and dislocation treated by posterior fixation and fusion with pedicle screwrod system between January 2006 and December 2012.There were 7 males and 1 female,at mean age of 31.9 years (range,19-49 years).Mean time interval between injury and surgery was 8.1 days (range,4-12 days).Fracture-dislocation classification was AO type C,Denis three-column injury,and Meyerding grade V.According to American Spinal Injury Association (ASIA),there 5 cases at grades A,1 at grade B,1 at grade C 1 at grade E.Fracture-dislocation segments included T5-T6 in 1 case,T12-L1 in 3,L1-L2 in 2,L3-L4 in 1 and L4-L5 in 1.Results Mean duration of surgery was 220.6 minutes (range,135-335 minutes) and mean intraoperative blood loss was 1 150 ml (range,500-2 400 ml).Seven cases sustained dural laceration during the operation,which were sutured or covered with autologous fat grafts,but 3 of them were subjected to cerebrospinal fluid leakage and healed after conservative therapy.Anatomic reduction was achieved in 6 cases,partial reduction in 1 and non-reduction in 1.Mean Cobb angle improved from 29.3 ° (range,8 °-51 °) preoperatively to 1.9 ° (range,-5°-10 °) postoperatively.After a mean follow-up of 39.3 months (range,2-76 months),2 cases were recovered from preoperative ASIA grade A and B to C respectively and 6 cases (4 A,1 C,1 E) revealed no significant improvement.There was no implant loosening or breakage.One case was died of lung-related complications at postoperative 4 years.One case sustained lumbar deep infection at postoperative 3 weeks and managed by debridement,irrigation,drainage and implant retention.Conclusion Posterior fixation and fusion is the general treatment principle for complete thoracolumbar fracture and dislocation,but the degree of reduction depends on severity of the injured spinal cord.

Treatment of hematomas in operation area after anterior approach surgery for cervical spondylosis / 中华创伤杂志

Objective To investigate the treatment and prevention strategies of hematomas in operation area after anterior approach surgery for cervical spondylosis.Methods A retrospective review was conducted on 12 with hematoma compression in operation area out of 785 patients managed by anterior cervical surgery from January 2007 to July 2013,including 10 males and 2 females at age ranging from 40-71 years (mean 56.8 years).Surgery method was anterior cervical corpectomy and interbody fusion using titanium mesh cage plus plate and intraoperative blood loss was 300-1 200 ml.Primary clinical manifestations were neurological dysfunction in 5 patients,dyspnea in 6,and both neurological dysfunction and dyspnea in 1.There were 10 patients with the presence of symptoms at postoperative 0.5-22 hours,1 at postoperative 73 hours,and 1 at postoperative 74 hours.All the 12 patients underwent a second anterior cervical exploration.Results There were 5 patients with epidural hematoma,6 with subcutaneous hematoma,and 1 with both hematomas.After surgical interventions,the patients presented improvement in respiratory and neurological function,with inapparent respiratory abnormality and improved neurological function at discharge.One patient was died of cardiovascular-associated disease after being discharged from hospital.The left 11 patients were followed up for mean 19.8 months (range,6-43 months),with improved Japanese Orthopedic Association (JOA) score at final follow-up.Conclusions Hematoma took place frequently in the early period,especially within 24 hours in operation area after anterior approach to cervical disorders and close attention should be paid to respiratory and limb sensation and motion functions.Early detection and early surgical interventions are the key countermeasures to avoiding the severe results.

Dermatofibrosarcoma Protuberans in Breast

Dermatofibrosarcoma protuberans is a slow-growing, but locally aggressive fibrous tumor that has a high rate of local recurrence after surgical resection. This tumor most commonly occurs in the trunk and proximal extremities. In this report we present a case of a 47-year-old woman with dermatofirbosarcoma protuberans in her breast, which is a very unusual site. Complete and careful resection is recommended for this type of tumor to prevent its recurrence.

The clinical analysis of free patellar implantation in repairing the defect of the knee of giant cell tumors / 中华外科杂志

<p><b>OBJECTIVE</b>To analysis the clinical effects of free patellar implantation in treating the defect of the knee joint after the excision of giant cell tumor in the distal femur and the proximal tibia.</p><p><b>METHODS</b>If the giant cell tumor in the distal femur and the proximal tibia invaded the articular surface, we resected the condyle of femur or tibia including the tumor, dissociated the patella and placed it in the condyle horizontally to repair the articular surface. The cruciate ligament was reserved in all the patients. The condyle of femur or tibia was replaced by the anterior surface or the articular surface of the patella respectively. The implanted patella was fixed by the screw to the contralateral condyle, and the remaining defect was filled by autogenous cancellous illium.</p><p><b>RESULTS</b>Nine patients were followed up 3 to 121 months, the average was 65 months. None of them recurred or metastated. The excellent and good rate of the functional evaluation of knee joints was 88.9%.</p><p><b>CONCLUSION</b>After resecting the condyle of femur or tibia including the tumors which invade the articular surface, we find that free patellar implantation is a suitable way to repair the defect of the knee.</p>

Auriculoterapia en pacientes asmáticos

Se realiza un estudio para evaluar la eficacia de la auriculopuntura en 30 asmáticos del área de salud de Aguada de Pasajeros, durante los meses de noviembre de 1992 a abril de 1993. El tratamiento se aplicó durante un mes, con seguimiento durante los 5 meses posteriores. Se observó una disminución en la frecuencia, intensidad y duración de las crisis de asma; la mayoría de los pacientes tuvo una evolución satisfactoria y no se presentaron complicaciones. Se concluye que la auriculoterapia es un método útil en pacientes con asma bronquial debido a su eficacia e inocuidad.

A study was conducted to evaluate the efficacy of auriculopuncture in 30 asthmatic patients from the health area of Aguada de Pasajeros between November, 1992, and April, 1993. The treatment was applied for a month, with a follow-up during the next 5 months. It was observed a reduction in the frequency, intensity and duration of the asthma crises. Most of the patients had a satisfactory evolution and there were no complications.
