Congenital anomalies, diseases, and injuries may result in osteochondral damage. Recently, a big hope has been given to somatic stem cells (SSCs) which are characterized as undifferentiated cells with an ability of long-term self-renewing and plasticity. They are adherent with a fibroblast-like morphology in vitro and express various surface markers (e.g. CD29, CD73, CD90, and CD105), but they are negative for CD31, CD34, CD45, and HLA-DR. SSCs secrete various bioactive molecules, which are involved in processes of regeneration. The main goal of the present study was the characterization and comparison of biological properties of SSCs obtained from adipose tissue, dental pulp, and urine concerning osteochondral regeneration. SSCs were maintained in an appropriate growth medium up to the third passage and were analyzed by light and electron microscope. The immunophenotype was analyzed by flow cytometry. The kinetics of proliferation was measured by MTT assay. Human Cytokine/Chemokine Multiplex Assay was used, and SSCs secretory profile was measured by Luminex MAGPIX® Instrument. Pellet cultures and a chondrogenic medium were used to induce chondrogenic differentiation. Osteogenic differentiation was induced by the osteogenic medium. Chondrogenic and osteogenic differentiation was analyzed by real-time PCR. SSCs had similar fibroblast-like morphology. They have similar kinetics of proliferation. SSCs shared the expression CD29, CD44, CD73, CD90, and CD105. They lack expression of CD29 and CD34. SSCs secerned similar levels of IL10 and IL18 while differing in IFN-gamma, IL6, IL8, MCP-1, and RANTES production. SSCs possess a similar capacity for chondrogenic differentiation but slightly differ in osteogenic differentiation. In conclusion, it can be emphasized that SSCs from adipose tissue, dental pulp, and urine share the majority of cellular characteristics typical for SSCs and have great potential to be used in osteochondral tissue regeneration.

The aim of this publication is to present a case report of a 38-year-old patient with traumatic astragalectomy and resultant foot reconstruction surgery using a combination of talus compensation by vertically placed tricortical autograft and pantalar arthrodesis with a retrograde calcaneotibial nail (hindfoot nail). The advantage of this treatment is based on a solid, stable osteosynthesis, while maintaining the length of the limb. Key words: traumatic talar extrusion, tibiocalcaneal arthrodesis, hindfoot nail, bone graft, pantalar arthrodesis.

Úvod: Zlomeniny proximálneho humeru predstavujú asi 4−5 % zo všetkých zlomenín. Terapia dislokovaných 3- a 4-časťových zlomenín je náročná a optimálna liečebná metóda je diskutabilná. Cieľom práce bolo porovnanie operačnej a neoperačnej terapie 3- a 4-časťových zlomenín proximálneho humeru u dospelých pacientov. Metoda: Od septembra 2010 do septembra 2013 sme na II. Ortopedicko-traumatologickej klinike Univerzitnej nemocnice Bratislava prospektívne vyhodnocovali operačnú verzus neoperačnú liečbu 3- a 4-časťových zlomenín proximálneho humeru. Pacienti zaradení do štúdie boli dospelí pacienti s 3- a 4-časťovými zlomeninami proximálneho humeru typu Neer IV, V a VI. V operačnej skupine bolo spolu 20 pacientov liečených pomocou uhlovo-stabilných dláh (Philos, Synthes) a intramedulárnych klincov (Multilock, Synthes). Skupinu tvorilo 13 žien (65 %) a 7 mužov (35 %). Priemerný vek bol 60,9?7,67 (52–80) rokov. Konzervatívna skupina obsahovala 19 pacientov. Dvanásť žien (63,2 %) a sedem mužov (36,8 %). Priemerný vek bol 65,1?9,4 (52−88) rokov. Poranená končatina sa fixovala použitím Gilchristovej bandáže na maximálne 3 týždne. Všetci pacienti boli hodnotení po 12 mesiacoch použitím skórovacieho systému podľa Constant- Murleyho a Oxford Shoulder Score. Druhotne boli hodnotené komplikácie liečby. Výsledky: Relatívne individuálne Constant-Murley Score v celej skupine liečenej operačne bolo priemerne 57,8?23,5 % (11−88 %). Oxford Shoulder Score priemerne 34,8?10,6 (10−46) bodov. Komplikácie boli zaznamenané u 12 pacientov (60 %). V skupine konzervatívnej bolo relatívne individuálne Constant-Murley Score po12 mesiacoch po úraze priemerne 60,9?20,9 % (16−90 %). Oxford Shoulder Score bolo priemerne 36,1?8,9 (15−48) bodov. Komplikácie boli prítomné u 4 pacientov (21,1 %). Záver: V tejto štúdii dislokovaných 3- a 4-časťových zlomenín proximálneho humeru bola operačná skupina pacientov, liečená zväčša použitím uhlovo-stabilných dláh, spojená so značným počtom komplikácií. Horšie funkčné výsledky operačnej skupiny boli porovnateľné s výsledkami skupiny neoperačnej. Pre dosiahnutie lepších výsledkov by sa starostlivo mala posudzovať indikácia operácie, výber pacienta, metóda operácie, operačné skúsenosti ako aj následná rehabilitácia. Kľúčové slová: zlomenina proximálneho humeru − operačná liečba − konzervatívna liečba − 3- a 4-časťové zlomeniny
Introduction: Proximal humerus fractures account for about 4−5% of all fractures. Treatment of 3- and 4-part fractures is difficult, and the optimal treatment option remains controversial. The aim of the study was to compare surgical and non-surgical treatments of 3- and 4-part fractures of the proximal humerus in adults. Method: A prospective study of surgical and non-surgical treatments of 3- and 4-part fractures of the proximal humerus was conducted at the 2nd Department of Orthopedics and Traumatology, University Hospital Bratislava, from September 2010 until September 2013. Patients included in the study were compliant adults patients with 3- and 4-part proximal humerus fractures Neer type IV, V and VI. Twenty patients were treated surgically. The group included 13 women (65%) and 7 men (35%). Mean age was 60.9?7.67 (52–80) years. Angle-stable plates (Philos, Synthes) and intramedullary nails (Multilock, Synthes) were used. The non-surgical group included 19 patients, consisting of 12 (63.2%) women and 7 (36.8%) men. Mean age of both sexes was 66.3?9.5 (52−88) years. Gilchrist bandage was applied for the maximum of 3 weeks. All patients were evaluated at 12 months from treatment using the Constant-Murley scoring system and the Oxford Shoulder Score. Treatment complications were evaluated as a secondary step. Results: The mean individual relative Constant-Murley score was 57.8?23.5% (11−88%) in the surgical group. The mean Oxford Shoulder score was 34.8?10.6 (10−46) points. Complications were recorded in 12 patients (60%). In the non-surgical group, the mean individual relative Constant-Murley score at 12 months from injury was 60.9?20.9% (16−90%). The mean Oxford Shoulder score was 36.1?8.9 (15−48) points. Complications were recorded in 4 patients (21.1%). Conclusions: In this study, surgical treatment patients with displaced 3- and 4-part proximal humerus fractures, mostly treated by angle-stable plates, showed a number of complications. Poor functional results of the surgical group were comparable to those of the non-surgical group. The indication for surgery, patient selection, type of surgery, surgical experience and subsequent rehabilitation should be carefully assessed for better results. Key words: proximal humerus fracture − surgical treatment − non-surgical treatment − 3- and 4-part fractures

PURPOSE OF THE STUDY: The vast majority of studies on fractures of the acetabulum are concerned with surgical treatment. All displaced fractures are presented as surgically treated. The purpose of this study was to evaluate the results of surgical and conservative treatment of patients with acetabular fractures in relation to the degree of fracture displacement. MATERIAL AND METHODS: We analysed 140 fractures of the acetabulum treated in our institution by different methods between 2009 and 2013. In addition to the use of Letournel´s classification, we allocated each fracture to one of six groups: 1. Sixty displaced fractures treated surgically, 2. Twenty three fractures with a displacement of more than 6 mm, 3. Eighteen slightly displaced fractures (2-3 mm in the acetabular roof or 4-5 mm in other parts of the acetabulum), 4. Twenty non-displaced fractures, 5. Six pelvic fractures involving the acetabulum and 6. Thirteen fractures of old people, mostly displaced but not examined by CT. Groups 2 to 6 were treated conservatively. In all patients, demographic and epidemiologic factors were analysed in relation to the patient's group assignment. In 107 patients, hip function was assessed using the Matta clinical grading system at a minimum follow-up of 12 months (average 3.16 years). Radiological status, time of admission, start of weight-bearing after the accident, working ability, mortality and complications were also evaluated. RESULTS: Non-displaced fractures were often associated with serious injury or polytrauma in 20 patients; not all of them had excellent functional outcome. (mean score, 17.25). Excluding two patients who developed avascular necrosis, fourteen slightly displaced fractures had a fixal score of 16.92. Sixteen patients with displaced fractures were managed conservatively due to their poor medical condition and other circumstances. Their functional outcome (mean score, 15.25) was significantly worse than that of the patients with non-displaced fractures (p=0.02) and worse than the outcome in patients with slightly displaced fractures, but the difference was not significant (p=0.32). No occurrence of accelerated post-traumatic arthritis was observed in these groups. The mean clinical score of 14.80 and 60% of excellent and good results were achieved in surgically treated patients. Eight of them were treated by primary hip arthroplasty and osteosynthesis. A total of 11 patients required total hip arthroplasty because of post-traumatic osteoarthritis, but only one from the group of slightly displaced fractures, all others from the group of surgically treated patients. DISCUSSION: Displaced fractures of the acetabulum are best treated by open reduction and internal fixation. The type of fracture and the quality of reduction influence the functional outcome. There are a few studies reporting long-term outcomes in conservatively treated acetabular fractures. Although conservative treatment continues to be the mainstay of treatment in most centres in the developing countries, it is obvious that not all of acetabular fractures can or must be treated surgically or identically. We found that, in many cases, surgery was too dangerous for the patient and his/her medical condition or that the result of surgery was doubtful, mostly because of a late presentation. In some cases, primary hip arthroplasty is a solution. Secondary total hip replacement is technically more demanding and has a higher rate of failure. CONCLUSIONS: Conservative treatment is the method of choice for the treatment of non-displaced acetabular fractures. Excellent or very good results can also be expected in slightly displaced fractures if acetabular roof involvement is minor. In displaced fractures, if the result of surgery is doubtful under various circumstances or if high-risk medical conditions are present in the patient, conservative treatment can be the method of choice with satisfying results. Key words: acetabular fractures, conservative treatment, degree of displacement, epidemiology of acetabular fractures.
