ABSTRACT
A retrospective analysis was performed among 8 patients with unilateral intraarticular calcaneal fracture, who were selected from the Department of Orthopaedics in Yangpu District Central Hospital of Shanghai. They were treated with the injectable bone graft MIIG[R] X3 combined with percutaneous reduction by leverage and axial fixation from June 2005 to November 2006. After treatment, the function of affected feet was evaluated according to the ankle-hindfoot score of the American Orthopaedic Foot & Ankle Society (totally 100 points). All the patients were rechecked with X-ray films periodically to observe the reaction between the materials and the host, the healing of fracture, the pain of limbs and joint motion. Eight patients were all followed up, the complication rate reached 12.5% (1/8), the improvement of Bohler angle excelled 18° to 25°, and that of Gissane angle exceeded 30° to 35°. Among the included patients, 6 cases achieved excellent effect and 2 cases good. All developed the bone union. None of all had complications, such as necrosis of skin, hematoma and deep infection.
ABSTRACT
0.05). Incision size,operating time,blood loss,hospital stay,medical device expenses,postoperative VAS and ODI,clinical outcomes,fusion rates,and complication rates were studied and tested with independent sample t test and x2 test.[Results]The mean follow-up was 19.1 months (range,12~25 months) in group A and 24.6 months (range,9~36 months) in group B.There were statistically significant differences in the incision size,operating time,blood loss,hospital stay and medical device expenses (P0.05).[Conclusion]Unilateral transforaminal lumbar interbody fusion with unilateral pedicle screw fixation has the advantages of small incision,little bleeding,no destruction of the contralateral structure,short operating time or hospital stay,low medical device expenses and good recovery.But the operation indications must be strictly defined.
ABSTRACT
[Objective]To explore the short-term outcome and surgical technique of minimally invasive unicondylar knee arthroplasty(MIS-UKA) for medial compartmental osteoarthritis of the knee. [Methods]Forty-five patients(48 knees) with medial compartmental osteoarthritis of knee treated by MIS-UKA from May 2005 to December 2008 were reviewed and analyzed.The pain and range of motion(ROM) of the knees were evaluated by HSS score system before and after MIS-UKA.Pre-and postoperative alignment of the lower limbs was measured and compared.Surgery indications and surgical technique of MIS-UKA were also summarized.[Results]Forty-three knees in 40 patients were followed up for a mean time of 24 months(12-40 months).The pain over medial compartment of the knees was subsided or relieved in all cases.The post-operative ROM of the knees was 0?~135?(mean 120?),and alignment was 2? varus on the average(0?~6? varus).HSS score increased from 70(60~82) to 90(75~95).The good-to-excellent rate was 92%.[Conclusion]MIS-UKA is an effective method for medial compartmental osteoarthritis of the knee.Surgery indications and surgical technique are the key factors for the final results.
ABSTRACT
[Objective]To explore the clinical value of discography followed by computed tomography for the treatment of multi-level lumbar disc degeneration. [Methods]Twenty-eight cases were enrolled from January 2005 to January 2008.There were 12 males and 16 females with average age of 38.2 years,ranging from 30 to 56 years.The level of degenerated disc included L3、4 and L4、5(9 cases),L4、5 and L5S1(15 cases),L3、4,L4、5 and L5S1(4 cases).The level of discography included L2、3(10 cases),L3、4(28 cases),L4、5(28 cases),and L5S1(26 cases) with a total of 92 discs.The painful discs(or responsible discs) were screened according to diagnostic criteria of provocative discography and treated with interbody fusion.[Results]Thirty-two responsible discs were screened in total of 92 discs.ODI scores between pre and post operation were significantly different(P
