PURPOSE OF THE STUDYVarious spine disorders are regularly treated by orthoses, and success of treatment depends on wearing these devices. In this study we examined the compliance, wear comfort, subjective stabilization and side effects associated with spinal orthoses using an individualized questionnaire and the Compact Short Form-12 Health Survey (SF-12).MATERIAL AND METHODSIn this prospective pilot study of randomized cross-over design, twelve healthy volunteers with a mean age of 31.2 years wore three different types of orthoses, each for one week: A hyperextension brace (HB), a custom-made semirigid orthosis (SO) and a custom-made rigid...

Acta Chir Orthop Traumatol Cech. 2017; 84(2):97-100 | DOI: 10.55095/achot2017/014  

PURPOSE OF THE STUDYAlthough total hip arthroplasty (THA) is one of the most successful orthopedic operations, the soft tissue trauma towards the periarticular musculature during surgical approaches remains a critical concern. However, the actual microstructural proof of muscle trauma on the level of the myofiber due to the surgical approach has never been claimed.MATERIAL AND METHODSPatients undergoing THA were prospectively enrolled and either operated by a direct lateral (DL) or a anterolateral minimally invasive approach (ALMI). Intraoperatively and at 6 months follow-up a needle biopsy was taken from the gluteus medius muscle and the...

Acta Chir Orthop Traumatol Cech. 2017; 84(2):101-105 | DOI: 10.55095/achot2017/015  

PURPOSE OF THE STUDYHamstring grafts are commonly used for ACL reconstruction. The purpose of our study is to determine the effects of the suspension fixation compared to graft cross-pinning transfixation, and the effect(s) of structural damage during the preparation of the graft on biomechanical properties of the graft.MATERIAL AND METHODSThe design of the study is a cadaveric biomechanical laboratory study. 38 fresh-frozen human hamstring specimens from 19 cadaveric donors were used. The grafts were tested for their loading properties. One half of each specimen was suspended over a 3.3mm pin, the other half was cross-pinned by a 3.3mm...

Acta Chir Orthop Traumatol Cech. 2017; 84(2):106-113 | DOI: 10.55095/achot2017/016  

PURPOSE OF THE STUDYA retrospective evaluation of the success rate of revision ACL reconstruction performed using BTB allograft in terms of the life expectancy of the procedure up to and over five years from surgery.MATERIAL AND METHODSOver a ten-year period, from 2003 to 2013, we performed 47 revision ACL reconstruction surgeries. The majority of the primary ACL reconstructions using BTB autografts were not performed at our site. The group observed included 16 women (34%) and 31 men (66%). The women were aged between 25 and 48 years, the median age being 32.5, and the men were aged between 25 and 46 years with the median age of 35.We...

Acta Chir Orthop Traumatol Cech. 2017; 84(2):114-119 | DOI: 10.55095/achot2017/017  

PURPOSE OF THE STUDYThe aim of the study was to assess the functional outcomes of rehabilitation in patients with surgically treated distal radius fractures in the early postoperative period. We compared the functional outcomes of patients undergoing standard rehabilitation with the group of patients whose postoperative rehabilitation was extended with shoulder girdle exercises of the affected upper limb while the wrist was immobilized. Several indices and variables were used for the assessment of the functional therapeutic outcomes of the affected wrist.MATERIAL AND METHODSForty patients (32 females and 8 males, the mean age 60.5 years)...

Acta Chir Orthop Traumatol Cech. 2017; 84(2):120-124 | DOI: 10.55095/achot2017/018  

PURPOSE OF THE STUDYClosed reduction and percutaneous fixation of nondisplaced talar neck fractures have been applied by some authors. The aim of this paper is to assess the results and complications of this minimally invasive technique.MATERIAL AND METHODSIn the period from 2009 to 2014, twenty-one patients with a talar neck fracture were observed after closed reduction and percutaneous screw fixation in the Traumatological Hospital in Brno. The mean age of the patients was 38 years (range 18-56 years). The mechanism of injury was a motor vehicle accident in 11 cases, a fall from height in six cases, a sports injury in 3 cases, and a fall...

PURPOSE OF THE STUDYThe aim of the study was to evaluate the safety and efficacy of the application of platelet- and leukocyte-rich plasma (L-PRP) in the treatment of lateral humeral epicondyle (ERH) as compared to the administration of corticosteroid therapy.MATERIAL AND METHODSIt was a prospective, double-blind and randomized clinical trial. It included a total of 25 cases of ERH in 23 patients aged 18 to 60 years. They were divided into two arms: L-PRP arm with 10 cases and corticosteroid arm with 15 cases. The therapy of L-PRP group: first application: 3 ml of native L-PRP without activation, second application: after 6 weeks, 3 ml...

Acta Chir Orthop Traumatol Cech. 2017; 84(2):133-137 | DOI: 10.55095/achot2017/020  

PURPOSE OF THE STUDYIn developing new or modifying the existing surgical treatment methods of spine conditions an integral part of ex vivo experiments is the assessment of mechanical, kinematic and dynamic properties of created constructions. The aim of the study is to create an appropriately validated numerical model of canine cervical spine in order to obtain a tool for basic research to be applied in cervical spine surgeries. For this purpose, canine is a suitable model due to the occurrence of similar cervical spine conditions in some breeds of dogs and in humans. The obtained model can also be used in research and in clinical veterinary practice.MATERIAL...

Cerclage Breakage in Trochanteric Revision - High Risk for Hip Endoprosthesis?Case report

M. J. KRAUS, A. M. NOWAKOWSKI

Acta Chir Orthop Traumatol Cech. 2017; 84(2):138-140 | DOI: 10.55095/achot2017/021  

We report a 72-year-old man who underwent fixation with a multifilament cerclage system after a peri-prosthetic trochanteric fracture (Vancouver A1). Failure of cerclage occurred after 23 month and revision of trochanteric attachment was performed due to non-union. Intraoperatively fragments of the cable were found between prosthesis head and liner. Cup and head were changed and the greater trochanter was re-attached after allograft-impaction. Based on the present case report multifilament cerclage cables should be used with precaution and might require a close and frequent follow-up given the possibility of cerclage breakage and consecutive catastrophic...
