Úvod: Cílem práce je pomocí analýzy vlastního souboru pacientů a aktuálních odborných publikací stanovit, v jakých případech lze zlomeniny střední části skafoidea léčit konzervativně krátkodobou sádrovou fixací s malým rizikem vzniku pakloubu. Materiál a metoda: Soubor 19 pacientů (17 mužů a 2 ženy) s průměrným věkem 31 let (rozsah 20–43, SD 7,3) se zlomeninami střední části člunkové kosti zápěstí indikovanými ke konzervativní léčbě. Diagnostika byla prováděna na základě RTG a CT vyšetření. Konzervativní terapie spočívala v přiložení sádrové fixace zápěstí a palce na dobu min. 6 týdnů u zcela nedislokovaných zlomenin (průměr 6,4 týdne, rozsah 6–10 týdnů). Ostatní zlomeniny byly imobilizovány sádrou celkem 9 týdnů. Všichni pacienti byli sledováni min. 6 měsíců. Výsledky: V odstupu 6 měsíců od úrazu uváděli 2 z pacientů mírné klidové bolesti (1× při zhojené zlomenině, 1× při pakloubu). Bolesti při pohybu nastávaly u 5 pacientů s rozvinutým pakloubem. Dobré zhojení zlomeniny v anatomickém postavení bylo pozorováno u 10 pacientů (53 %), ve 2 případech (11 %) došlo v průběhu hojení k úhlové dislokaci a v 7 případech (37 %) se rozvinul pakloub. Závěr: Konzervativní terapie je vhodná pro zlomeniny střední části skafoidea nedislokované a s dislokací kostních fragmentů do 1,5 mm. U těchto zlomenin je při konzervativní terapii nízké riziko rozvoje pakloubu. RTG zobrazení je nedostatečné. CT vyšetření je nutné zhotovit při nezachycení linie lomu na RTG snímcích při výrazném klinickém nálezu, obzvlášť ve skupině pacientů s typickým výskytem zlomeniny střední části skafoidea, tzn. u mladých mužů ve věku mezi 25. a 40. rokem. Rozhodnutí o druhu léčby musí vždy vycházet z CT vyšetření.
Introduction: The goal of this work is to determine, using the analysis of our own patient group and current professional publications, in which cases fractures of the scaphoid waist can be treated conservatively by short-term plaster fixation with a low risk of non-union developing. Material and method: A group of 19 patients (17 men and 2 women) with the mean age 31 years (range 20–43, SD 7.3) with fractures of scaphoid waist were indicated for conservative treatment. The diagnosis was made on the basis of X-ray and CT examination. Conservative therapy consisted of applying plaster fixation of the wrist and thumb for a minimum of 6 weeks in completely non-dislocated fractures (mean 6.4 weeks, range 6–10 weeks). The other fractures were immobilized with a plaster cast for a total of 9 weeks. All patients were followed for at least 6 months. Results: At 6 months after the injury, 2 of the patients reported mild pain at rest (1× with healed fracture, 1× with a non-union). Pain during movement occurred in 5 patients with a developed non-union. Good healing of the fracture in the anatomical position was observed in 10 patients (53%), in 2 cases (11%) an angular dislocation occured during healing, and in 7 patients (37%) the result of treatment was a non-union. Conclusion: Conservative therapy is suitable for fractures of the scaphoid waist without dislocation and with dislocation of bone fragments up to 1.5 mm. In these fractures, conservative therapy has a low risk of non-union developing. X-ray imaging is insufficient. In case the fracture line does not appear on the X-ray and there is a significant clinical finding, especially in the group of patients with a typical occurrence of a fracture of the scaphoid waist, i.e. in young men aged between 25 and 40 years, CT examination must be performed. The decision on the type of treatment must always be based on the CT scan.

Several accessory bones can be found around the wrist, which may pose a diagnostic challenge. Hereby, we report a unique case of a traumatic fracture of an aberrant os styloideum in a 66-year-old male. The patient presented with a swollen dominant right hand and a hematoma on its anterior and posterior aspects, as a result of a fall on an outstretched hand. The diagnosis was based on a CT scan, which showed a fractured accessory bone between the distal portion of the capitate bone and the base of the third metacarpus. Due to its typical location, the ossicle was identified as os styloideum. The patient was treated conservatively and the symptoms subsided on a short forearm cast after 2 weeks. At a 12-month follow-up, no other episodes were declared. Strong anatomical knowledge and sharing of such cases is essential for proper diagnosis and treatment of this very rare condition.

Intraoseální ganglion je relativně zřídkavou příčinou chronické bolesti zápěstí. Nejčastěji ganglia nacházíme v os lunatum a os scaphoideum. V mnoha případech je jejich součástí i extraoseální složka, přičemž obě části mohou být zdrojem klinických potíží. V naší kazuistice prezentujeme pacientku s atypickou chronickou bolestí volární části zápěstí, u které byl diagnostikován intraoseální ganglion os scaphoideum s volární extraoseální složkou jakožto hlavním zdrojem potíží. U pacientky byly odstraněny obě složky ganglia a defekt v os scaphoideum byl vyplněn spongioplastikou, což vedlo k vymizení klinických obtíží a eliminaci rizika fraktury os scaphoideum. V práci je popisována a diskutována diagnostická a terapeutická rozvaha u pacientů s nálezem intraoseálních a extraoseálních ganglií zápěstí v návaznosti na relevantní literaturu.
Intraosseous ganglion is a relatively rare cause of chronic wrist pain. The ganglion is most commonly found in the os lunatum and os scaphoideum and in many cases includes an extraosseous component, both of which can be a source of clinical difficulty. In our case report, we present a patient with atypical chronic volar wrist pain who was diagnosed to have an intraosseous ganglion of the os scaphoideum with a volar extraosseous component as the main source of her problems. The patient had both components of the ganglion removed and the defect in the os scaphoideum was filled with an autogenous cancellous bone graft resulting in resolution of the clinical complaints and elimination of the risk of os scaphoideum fracture. The diagnostic and therapeutic considerations in patients found to have an intraosseous ganglion of the wrist with an extraosseous component are described and discussed in relation to the relevant literature.

PURPOSE: The accessory bones around the elbow are very rare variant structures, present in approximately 0.7% of cases. They can cause diagnostic problems and can be mistaken for pathological structures, especially when pain and limitation of elbow movements are present and a trauma can be traced in the patient's history. They are of different nature, either presenting within muscle tendons as sesamoids (brachialis and triceps brachii muscles) or presenting intra-articularly probably as separated or accessory ossification centres. The least common is the os supratrochleare anterius. METHODS: We present a case of a young male, featuring chronic blocking and 20° limited flexion of his right elbow, which bothered him during his occupation as a locksmith. In history, he suffered minor trauma to the elbow 20 years ago. X-ray and CT showed a large ossicle in the coronoid fossa of the humerus. RESULTS: The ossicle was surgically extracted in small pieces. The patient left satisfied with no mention of complaints. CONCLUSION: The os supratrochleare anterius is a very rare accessory bone of the elbow, located in the coronoid fossa of the humerus which can mimic many pathological states, and limit movements and causing pain around the elbow.

PURPOSE OF THE STUDY: The preclinical study aimed to compare the healing of segmental bone defects treated with biodegradable hyaluronic acid and tricalcium phosphate-based hydrogel with the established autologous spongioplasty. Another aim was to evaluate the hydrogel as a scaffold for osteoinductive growth factor of bone morphogenetic protein-2 (BMP-2) and stem cells. MATERIAL AND METHODS: The study was conducted in an in vivo animal model. A standardized rabbit model of a 15 mm long segmental bone defect of left radius was used. A total of 40 animals were divided into 5 groups of 8 individuals. In the KO- (negative control) group, the created defect was left to heal spontaneously. In the KO+ (positive control) group, the defect was filled with morselized bone autograft prepared from the resected segment. In the study group A, the defect was filled with hydrogel based on hyaluronic acid derivative and tricalcium phosphate. In the study group B, the defect was filled with hydrogel based on hyaluronic acid derivative, tricalcium phosphate and bone marrow aspirate. In the study group C, the defect was filled with hydrogel based on hyaluronic acid derivative, tricalcium phosphate, bone marrow aspirate and BMP-2. Healing was assessed using radiographs at 1, 6, and 12 weeks postoperatively and histology specimens were collected at 16 weeks postoperatively. RESULTS: Altogether 35 rabbits survived (KO- 7, KO+ 7, A 7, B 6, C 8) until the end of the study. As concerns the radiographic assessment, the best results were achieved by the groups KO+ and C, where new bone formation across the entire width of the bone defect was clearly seen at 6 and 12 weeks and the osteotomy line was completely healed too. At 12 weeks, complete bone remodelling was observed in all animals in the group KO+, whereas in the group C, bone remodelling was fully completed in 5 animals and partially completed in 3 animals. In terms of histological assessment, however, the best results were achieved by the group C, where the bone defect was completely remodelled into lamellar bone in 7 specimens, while in 1 specimen it healed with bony callus formation. In the group KO+, the defect was healed in 4 specimens by cartilaginous callus with loci of remodelling into bony callus, in 2 specimens the bony callus was predominant with cartilaginous callus areas, and only one defect was completely remodelled into lamellar bone. DISCUSSION: Compared to autografts that manifest osteogenic, osteoinductive and osteoconductive properties, the biodegradable hyaluronic acid and tricalcium phosphate-based hydrogel has osteoconductive properties only. Thus, it was also tested in our study as a scaffold for bone marrow cells and BMP-2 osteoinductive growth factor. Thanks to its semi-liquid properties, the biodegradable hyaluronic acid and tricalcium phosphate-based hydrogel is a promising material for use in 3D printing. CONCLUSIONS: The preclinical study in an in vivo animal model confirmed the beneficial effect of the biodegradable hyaluronic acid and tricalcium phosphate-based hydrogel on the healing of critical-size segmental bone defects. Better healing of these defects was also confirmed for filling composed of hydrogel and BMP-2 osteoinductive growth factor. The benefit of bone marrow aspirate mixed with hydrogel was not confirmed. KEY WORDS: bone defect, non-union, rabbit, hyaluronic acid, calcium phosphate, stem cells, BMP-2, scaffold, bone healing, spongioplasty.

PURPOSE OF THE STUDY The study aimed to propose an optimal based fl ap creation with the view to ensure long-term survival of the interposition arthroplasty. MATERIAL AND METHODS A total of 28 dorsal wrist capsules were collected from 16 cadavers (with age range at death 18 to 80 years, with no visible wrist pathology). Altogether 112 histological specimens were obtained from these 28 samples. Post-hoc Dunn's tests were used to analyse the percentage of vascularisation of individual sides of the dorsal capsule (circumference and area) at the 0.05 level of signifi cance. Spearmann's correlation analysis was used to assess the effect of age on vascularization of the dorsal wrist capsule. In cadavers in whom both capsules were collected, the limbs were compared. For the sake of comparison, the Wilcoxon matched pairs test was used. RESULTS Regarding statistical signifi cance, the largest share of the total circumference and area of the measured vessels of the dorsal capsule is constituted by the distal side (35.2% of the circumference and 30.9% of the area). The blood supply of the dorsal capsule received on the ulnar side is the lowest (12.9% of the circumference and 17.6% of the area). There was no signifi cant effect of age on vascularization of the dorsal wrist capsule confi rmed. Also, the comparison of vascularization of both limbs from a single cadaver did not yield any statistically signifi cant results. DISCUSSION Proximal row carpectomy is a long-established surgical technique used to manage the degenerative changes in the wrist. Our results showed the best vascularization on the distal and radial sides of the dorsal wrist capsule. In this light, the distally-based fl ap or the fl ap described by Berger, which respects the clinically important ligaments, appear to be the least invasive and help maintain the future stability of the wrist. CONCLUSIONS In clinical practice, we advise that a radially-based fl ap according to Berger is created and the distal side of the dorsal capsule, the most vascularized portion based on our results, is preserved as much as possible. The fl ap created in this manner also preserves the important carpal ligaments and appears to the authors of this study to be the most benefi cial, also with respect to the presence of the largest arteries, contrary to the distal side. Another option is to use a distally-based fl ap for interposition arthroplasty. Key words: interposition arthroplasty, proximal row carpectomy, vascularization, degenerative changes, wrist.

There are many osseous variants that occur around the elbow joint such as supracondylar process, supratrochlear foramen, accessory ossicles, and others. Scientific databases were searched for variants around the elbow joint. Elbow radiographs from our center demonstrating some of these findings were included in the study. The aim of the present review was to provide comprehensive information on the terminology, prevalence, history, etiology, and clinical importance of these variants. These anatomical variants are important for radiologists while interpreting radiographs, computed tomography, and magnetic resonance imaging for trauma and orthopedic surgeons during osteosynthesis at the distal humerus, proximal ulna, and radius.
BACKGROUND: Approximately, one-third of patients with tumors of proximal humerus will require an extra-articular resection to achieve oncologic margins. This procedure yields poor functional outcomes with a considerable rate of revisions. Unconstrained implants are prone to instability hindering also function of the elbow and hand, whereas constrained shoulder reconstructions suffer from early aseptic loosening of the glenoid component due to bone overload. The purpose of this study was to develop a constrained implant suitable for extra-articular resection with loss of function in deltoid and rotator cuff, which would provide both stability and passive motion, whilst also decreasing the risk of aseptic loosening of the glenoid component. METHODS: In cooperation with Czech Technical University in Prague, we devised an implant consisting of two constrained joints in series connected by a dumbbell piece. The biomechanical analysis showed a reduction of load transfer to the glenoid component with a torque of 8.6 Nm capable of generating an 865-N pulling force on bone screw to just 0.07 Nm, hence shielding the glenoid component from undesired forces and decreasing the risk of aseptic loosening. Three patients with extra-articular resection with a total loss of function of both rotator cuff and deltoid muscle received this type of reconstruction. The average follow-up was 16 months. RESULTS: The surgical technique is straightforward. The surgery took 175 min on average with average blood loss of 516 ml. There were no surgical- or implant-related complications. All three patients were pain-free and had a stable shoulder joint after the reconstruction. All had fully functional elbow, wrist, and hand joints. The average Musculoskeletal Tumor Society (MSTS) score was 21/30 (70%). All patients were pleased with the results. CONCLUSION: The presented innovative implant design has demonstrated to be a promising alternative for reconstruction in these challenging cases.
