PURPOSE OF THE STUDYThe present study aimed to analyse both, the functional outcome and quality of life after surgical treatment of periprosthetic fractures following TKA.MATERIAL AND METHODSA retrospective review of all periprosthetic fractures following knee arthroplasty which have been surgically treated at our institution between January 2005 and January 2012 was conducted. Beside epidemiologic data, type of surgery and postoperative complications were recorded. The functional outcome was assessed using range of motion, Knee Society Score and VAS to evaluate pain. Quality of life was evaluated using SF-36 and WOMAC. Furthermore patients...

INTRODUCTIONAlternative fusion expanders are in clinical use for instrumented posterolateral fusion (PLF) to avoid donor site morbidity in autologous bone graft (ABG) harvesting. Purpose of this study was to evaluate demineralized bone matrix (DBM) in PLF as alternative to the gold standard of ABG in acute traumatic vertebral body fractures of the thoracolumbar spine.MATERIAL AND METHODSWe retrospectively identified 101 patients with acute traumatic vertebral body fractures of the thoracic and lumbar spine who were treated with instrumented PLF in our level one trauma center between 2005 and 2011. Patients with a primary paraplegia, osteodepriving...

Acta Chir Orthop Traumatol Cech. 2015; 82(2):126-134 | DOI: 10.55095/achot2015/018  

PURPOSE OF THE STUDYA consensual classification of the periprosthetic interface membrane obtained at revision total joint arthroplasty was published by Morawietz et al. in 2006. Based on histomorphological criteria, four types of periprosthetic membrane were proposed: type I, aseptic failure; type II, septic failure; type III, combined type (carrying signs of both type I and II); and type IV, indeterminate type. The aim of this study was to find out whether and to what extent the Morawietz system would be suitable for use at an independent institution involved in the evaluation of periprosthetic membranes for a long time. Should it appear that...

Acta Chir Orthop Traumatol Cech. 2015; 82(2):135-139 | DOI: 10.55095/achot2015/019  

PURPOSE OF THE STUDYGrowth factors produced by platelets enhance tissue healing. The aim of this study was to confirm or disprove the hypothesis that, in anterior cruciate ligament (ACL) reconstruction, the application of platelet-rich plasma (PRP) into the tibial and femoral tunnels and in the graft enhances graft maturation and graft-bone interface healing and thus improves knee function at 3 and 12 months post-operatively in comparison with the control group.MATERIAL AND METHODSA total of 40 patient had the surgery; 20 underwent single-bundle hamstring reconstruction with PRP application (PRP group) and 20 had the same surgery without...

Acta Chir Orthop Traumatol Cech. 2015; 82(2):140-144 | DOI: 10.55095/achot2015/020  

PURPOSE OF THE STUDYThe objective of this study was to establish relative fixation strengths of proximal femoral nail (PFN), dynamic hip screw (DHS), monolateral external fixator (EF), and cannulated screw (CS) in basicervical hip fracture model.MATERIAL AND METHODSThe study involved four groups of implanted composite proximal femoral synthetic bones of eight specimens per group; nailing with PFN, DHS, fixation with three cannulated screws, and EF. 70˚ osteotomy was performed to simulate a Pauwels Type 3 basicervical fracture. Minimum preload of 100 N was applied before loading to failure. The constructs were subjected to cyclic loading...

Acta Chir Orthop Traumatol Cech. 2015; 82(2):145-151 | DOI: 10.55095/achot2015/021  

PURPOSE OF THE STUDYIn view of increasing interest in a relationship between the surface of an implant and its behaviour and longevity in total hip arthroplasty (THA), the aim of this study is to present the clinical and radiographic results, as well as complications, of hip replacement surgery using the cemented femoral stem SAS I.MATERIAL AND METHODSA total of 298 cemented femoral stems SAS I were implanted in 275 patients at our department between 1996 and 2005. The patient average age was 72.1 years, with the range from 64 to 92 years. The pre-operative diagnoses were as follows: primary osteoarthritis in 179 (30.1%); post-dysplastic...

Acta Chir Orthop Traumatol Cech. 2015; 82(2):152-156 | DOI: 10.55095/achot2015/022  

PURPOSE OF THE STUDYThe os peroneum is a sesamoid bone found within the peroneus longus tendon and is present in the form of ossification on radiographs in 8-26% of the population. It is most likely the result of stress in the lateral side of the foot in connection with genetic factors. The factors affecting os peroneum development include anatomical changes, among others the length of the metatarsals especially because of the main tendon insertion on the first metatarsal bone.MATERIAL AND METHODSIn the study, 768 standardised radiographs of feet of the Caucasian population, taken between 2006 and 2012 in the Vamed Mediterra hospital (Mostiště,...

Fragility Fractures of the Pelvis: Should they Be Fixed?Current concepts review

P. M. ROMMENS, S.-O. DIETZ, C. OSSENDORF, P. PAIRON, D. WAGNER, A. HOFMANN

Acta Chir Orthop Traumatol Cech. 2015; 82(2):101-112 | DOI: 10.55095/achot2015/015  

Due to the aging population, there is an increasing number of fragility fractures of the pelvis (FFP). They are the result of low energy trauma. The bone breaks but the ligaments remain intact. Immobilizing pain at the pubic region or at the sacrum is the main symptom. Conventional radiographs reveal pubic rami fractures, but lesions of the dorsal pelvis are hardly visible and easily overlooked. CT of the pelvis with multiplanar reconstructions show the real extension of the lesion. Most patients have a history of osteoporosis or other fragility fractures. The new classification distinguishes between four categories of different and increasing instability....

Sequential Subtrochanteric Femoral Fracture after Atypical Diaphyseal Fracture in a Long-Term Bisphosphonate User: A Case ReportCase report

K.-T. PARK, K.-B. LEE

Acta Chir Orthop Traumatol Cech. 2015; 82(2):157-160 | DOI: 10.55095/achot2015/023  

Recent reports have found a relationship between long-term bisphosphonate therapy and the occurrence of low-energy subtrochanteric or diaphyseal atypical femoral fractures. These fractures usually occur at only one site in the same bone. We report a rare case of a patient with sequential atypical femoral fractures (first, a diaphyseal fracture, and second, an ipsilateral subtrochanteric fracture) after low-energy trauma. We present the clinical and operative findings and discuss how to prevent subsequent atypical femoral fractures. This case indicates that an atypical subtrochanteric femoral fracture can occur after an atypical diaphyseal fracture...

Acta Chir Orthop Traumatol Cech. 2015; 82(2):161-166 | DOI: 10.55095/achot2015/024  

Congenital dislocation of the knee and congenital permanent dislocation of the patella are rare disorders usually associated with complex syndromes. Two cases of siblings, girl and boy, who had the same clinical phenotype of this disorder are presented. The diagnosis of Desbuquois dysplasia was made and its autosomal recessive heredity was confirmed by genetic analysis. DNA samples were sent for a molecular genetic analysis of the skeletal dysplasia. The girl was surgically treated for a complete (grade 3) anterior dislocation of the tibia on the femur in the first year of life. Redressing casts had not previously been applied to avoid the risk of...
