PURPOSE OF THE STUDYUltrahigh molecular weight polyethylene (UHMWPE) is today the most frequently used bearing surface in total joint replacements (TJR) because of its properties, i.e., excellent biocompatibility, good mechanical and tribological performance and high wear resistance. UHMWPE liners are the most loaded TJR components and, therefore, their properties are decisive for TJR longevity. This study had three objectives: 1) to evaluate the oxidative degradation of explanted UHMWPE components; 2) to look for a statistically significant relationship between the extent of oxidative degradation and the durability of joint replacements; and 3)...

Acta Chir Orthop Traumatol Cech. 2016; 83(3):163-168 | DOI: 10.55095/achot2016/024  

PURPOSE OF THE STUDYThe alloplastic materials currently used for protective surface layers on implants were tested in vitro under microbiological laboratory conditions by contamination with microbial agents most frequently found in deep infection of total joint replacements. The objective was to find out how the resistance to bacterial colonisation was related to different surface finishes.MATERIAL AND METHODSEach of 14 samples of alloplastic material currently used in the manufacture of orthopaedic implants was inoculated with each of the group of microorganisms most frequently infecting joint replacements; these were Staphylococcus...

Acta Chir Orthop Traumatol Cech. 2016; 83(3):169-174 | DOI: 10.55095/achot2016/025  

PUPOSE OF THE STUDYThe treatment of osteochondral lesions of weight-bearing joints remains a serious therapeutic challenge, largely due to the minimal ability of articular hyaline cartilage to regenerate. The authors present the long-term clinical and MRI results of treating deep chondral and osteochondral defects of the ankle joint by the method of implantation of autologous chondrocytes in the form of a solid chondrograft.MATERIAL AND METHODSThe method of solid chondrograft implantation in the ankle joint was used in our Department from the year 2003. Between 2003 and 2013, this method was used in 31 patients, 16 men and 15 women. Their...

Acta Chir Orthop Traumatol Cech. 2016; 83(3):175-181 | DOI: 10.55095/achot2016/026  

PURPOSE OF THE STUDYThe aim of this prospective study was to evaluate, at one year of follow-up, radiographic and clinical results of total knee arthroplasty (TKA) performed with use of Zimmer® Patient Specific Instruments (PSIs) which allow for planning and customising each patient's TKA.MATERIAL AND METHODSOf the patients with knee arthritis who were eligible for joint replacement, 23 were randomly selected and included in this study. There were 11 men and 12 women, with 11 right and 12 left knee joints. On the basis of pre-operative CT scans, PSI custom-made pin guides, which conformed to the individual patient's anatomy, were produced...

Positions of Sustentacular Screw in Osteosynthesis of Calcaneal Fractures: Clinical and Radiographic StudyOriginal papers

Acta Chir Orthop Traumatol Cech. 2016; 83(3):182-185 | DOI: 10.55095/achot2016/027  

PURPOSE OF THE STUDYThe aim of the study was to analyse the options for sustentacular screw placement in osteosynthesis of intra-articular fractures of the heel bone and to assess the effect of various screw positions on failure to maintain the reduction in the post-operative period. In addition, problems related to screw-end protrusion over the medial cortical bone or to screw penetration into the talocalcaneal joint were assessed.MATERIAL AND METHODSThe group comprised 23 patients with a total of 25 intra-articular fractures of the heel bone treated by surgery. The procedure involved insertion of a sustentacular screw under fluoroscopic...

PURPOSE OF THE STUDYThe aim of this pilot study was to develop The Eastbourne Miami-J Protocol for care of cervical injuries within the community. Led by orthopaedic senior practitioners, a multidisciplinary approach was developed to provide education and collar care for patients on a weekly basis.MATERIALS AND METHODSA total of 51 patients (17 male and 33 female), mean age 74 years (21 to 95) with CT confirmed cervical injuries during November 2010 and May 2014 followed the Eastbourne Miami-J Protocol.RESULTSPatients required collar care on average for 7.25 weeks. Thirty-two patients had single level cervical injuries with C2 the...

Acta Chir Orthop Traumatol Cech. 2016; 83(3):189-193 | DOI: 10.55095/achot2016/029  

The case of a 15-year-old girl with a large ganglioneuroma in the mediastinum and spinal canal is presented. The tumour initially manifested as scoliosis. Its diagnosis was made on the basis of CT scanning and magnetic resonance imaging, and confirmed by thoracoscopic mediastinal biopsy. Radical tumour excision was indicated. The first stage involved removal of the tumour from the spinal canal through a posterior approach, and transpedicular fixation of the spinal column with correction of the curve. At the second-stage procedure, the tumour was removed from the pleural cavity and mediastinum through thoracotomy. At two years after surgery, the spondylodesis...

Acta Chir Orthop Traumatol Cech. 2016; 83(3):194-197 | DOI: 10.55095/achot2016/030  

Displaced fractures of the acromion are rare injuries. A 45-year-old lady presented with an isolated acromion fracture (type III, Kuhn classification) resulting from a direct blow to the top of her right shoulder in a fall while skiing. After standard clinical and radiological examination of the shoulder, an open reduction and internal plate fixation using a postero-superior approach to the scapula was performed. Early rehabilitation of the arm and shoulder was initiated. At 50 days after surgery the patient achieved a full range of motion in her right shoulder and muscle strength equal to that of the contralateral extremity. By 12 weeks radiographic...

Acta Chir Orthop Traumatol Cech. 2016; 83(3):198-201 | DOI: 10.55095/achot2016/031  

This study describes a diagnostic and therapeutic algorithm in a 53-year-old male patient who was diagnosed with a synovial chondromatosis of the knee joint extending to the popliteal fossa and soft tissues around the knee. Because of the presence of massive nodules, the patient was indicated for total synovectomy, with removal of pathologically changed cartilaginous tissue, performed by combined anterior and posterior approaches to the knee joint.Despite complete removal of the synovium and loose cartilage bodies and the patient's pain relief in the post-operative time, three years after the operation new problems appeared. Magnetic resonance...
