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: Simple bone cysts (SBCs) are the most common benign bone lesions in childhood. There are many different methods in the treatment of SBCs. There is no consensus on which method to use in the treatment. In this study, we compared the results of allogeneic bone graft or synthetic bone graft in addition to fl exible intramedullary nail (FIN) for SBC located in the humerus. MATERIAL AND METHODS: This retrospective study comparing the data of 19 (group 1: 8 curettage, allograft and FIN; group 2: 11 curettage, synthetic graft and FIN) patients with a mean age of 11.4 (6 to 26; seven female, twelve male) who were surgically treated in our hospital for humeral SBC between April 2014 and January 2020. Patient data included age, sex, anatomical side, stage of the cyst, pathological fracture, previous treatments and complications. RESULTS: The mean follow-up period was 33.7 months (12 to 61). The average last follow-up Musculoskeletal Tumor Society functional scores for groups 1 and 2 were 27.8 (20 to 30) and 28.6 (21 to 30) (P > 0.05). Complete or signifi cant partial radiographic healing rates were achieved in group 1 (75%) compared with group 2 (81.9%). The reoperation rates for groups 1 and 2 were 62.5% (5/8; three for nails removed, two for recurrence) and 36.3% (4/11; two for nails removed, two for recurrence). One patient in group 2 had a 15° varus deformity due to recurrence. No other complications were observed. CONCLUSIONS: The combination of curettage-grafonage FIN is a common treatment method in recent years, as it provides early cyst healing and limb mobilization in SBCs located in the upper extremity. For defects after curettage of the bone cysts, allogeneic or synthetic grafts (granule b-tricalcium phospate) which have similar results in terms of healing can be used as an alternative to each other. KEY WORDS: allografts, bone cysts, bone nails, synthetic grafts, humerus.

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.

PURPOSE OF THE STUDY Although there are numerous studies on outcomes and comparison of open and closed reduction but there is no clarity on relationship between outcomes and complications with type of surgical intervention done for Type 3 Gartland supracondylar humerus fracture. The aim of this study is to compare the outcomes and complications of closed vs open reduction in Type 3 Gartland supracondylar humerus fractures. MATERIAL AND METHODS Electronic literature searches of Embase, MEDLINE and the Cochrane Library was conducted in February 2022 using the terms "supracondylar", "humerus", "fracture", "Gartland type 3" and synonymous. The data extracted included the study details, demographic data, procedure performed, final functional and cosmetic outcome according to Flynn criteria and complications of included studies. RESULTS Pooled data analysis revealed no significant difference in mean satisfactory outcome rate according to Flynn cosmetic criteria in open group (97%, 95% CI 95.5%-98.5%), as compared to closed group (97.5%, 95% CI 96.3%-98.7%), although a statistically significant difference in mean satisfactory rate according to Flynn functional criteria in open group (93.4%, 95% CI 90.8%- 96.1%) as compared to closed group (98.5%, 95% CI 97.5%-99.4%) was noted. On separate comparison of the two-arm studies, closed reduction favoured better functional outcomes (RR 0.92, 95% CI 0.86-0.99). CONCLUSIONS Closed reduction and percutaneous fixation have better functional outcome than open reduction with K-wire fixation. But there was no significant difference in cosmetic outcomes, overall complication rate and nerve injury with either open or closed reduction. The threshold of converting a closed reduction to an open reduction in supracondylar humerus fractures of children should be high. Key words: supracondylar humerus, open reduction, percutaneous pinning, Flynn criteria.

PURPOSE OF THE STUDY: The purpose of this study is to compare the stability of different fi xation methods in high pediatric supracondylar humerus fractures with a fi nite element analysis method. MATERIAL AND METHODS Transverse, lateral oblique, and medial oblique fracture models were created in a ten years old boy's distal humerus. Eight different fi xation methods were applied to each fracture model. Displacement of the fracture models was measured under the translational and torsional forces. RESULTS In the transverse fracture model; the 6th method provided the best stability in internal rotation, external rotation, and extension loading. In varus 7th method, valgus 8th, and fl exion the 5th and 2nd methods had the best stability. In the lateral oblique fracture model; the 7th method had the best stability in all loading directions except fl exion and the 6th method had the best stability in fl exion and had acceptable values in all other directions except valgus and external rotation. In the medial oblique fracture model; the 6th method had the best stability in all directions except varus. 3rd method was the best fi xation type against varus and the second stable fi xation type in all other directions. CONCLUSIONS Combining lateral antegrade with lateral retrograde wire and lateral condylomedullary wire provides strong stability in the lateral oblique fracture. Two condylomedullary Kirchner wires and one antegrade lateral wire results in a strong stability in the medial oblique fracture. Medial-lateral condylomedullary and lateral antegrade wires provided the best stability against varus in transverse and lateral oblique fractures. KEY WORDS: high pediatric supracondylar humerus fracture, percutaneous fi xation method, metaphyseal-diaphyseal junction, fi nite element analysis.
Glenohumeral joint is the most frequently dislocated joint of the human body. Concomitant fractures of the coracoid process and tuberculum majus in humeral dislocation of the shoulder joint are rarely described. Concomitant fractures are results of a significant contraction of the surrounding muscles and rotator cuff during a cerebral paroxysm. Due to the small number of cases, the treatment of such injuries is not simple and it is based on an algorithm for treatment of isolated injuries of these anatomical structures. In this case report, we describe a concomitant fracture of the coracoid process and tuberculum majus during an anterior shoulder dislocation in 25-year-old patient after an epileptic seizure. The injury was treated in our department surgically, with a good functional result. The absolute Constant score for the operated arm is 95 points, the relative Constant score is 97%, DASH score 0, VAS score 0.

PURPOSE OF THE STUDY Aseptic pseudoarthrosis (nonunion, PSA) of the humeral shaft is one of the serious complications in the treatment of fractures in this area. In a retrospective study, the authors described different methods of treating patients with this complication using predictive factors. MATERIAL AND METHODS Based on the definition of nonunion and the criteria, 14 patients (N=14) with the mean age of 56 years (32-78), namely 8 men and 6 women were included in the study. All patients were followed up clinically and radiologically at 1, 3, 6, 9, 12 months and every 3 months until the condition stabilized. The follow-up period was 11-72 months, with the average of 22 months. According to the AO classification, the fractures were classified as: 4-A1, 1-A2, 4-A3, 1-B1, 3-B2 and 1-C2. Based on the Weber-Čech classification, 2 cases of pseudoarthrosis were hypertrophic, 4 oligotrophic and 8 atrophic. According to the Non-Union Scoring System (NUSS), 5 patients reached the score under 25 points, 3 patients received 25-50 points, 4 patients 51-75 points and two patients over 76 points. In five cases, the fracture displacement index (FDI) was above 100%. In 11 patients, PSA was in the proximal and middle third and in three patients in the distal third of the humerus. METHODS Of the whole group (N=14), the nail was used in 5 cases (36%) - in 3 cases NUSS of up to 50 points and in 2 cases over 76 points. The plate was used in 9 cases (64%). In patients with NUSS of up to 50 points - in 1 case after conservative treatment, in 1 case for augmentation of nail, in 3 cases for augmentation of Prévot nails. In 4 cases with NUSS of 51-75 points a plate was replaced. Osteosynthesis was always supplemented by Judet's decortication or resection of atrophic bone and spongioplasty by autologous graft. RESULTS Shoulder function measured by the Constant Murley score (C-M) improved from 53 to 89 points (from the range of 36-76 points to the range of 75-100 points). The function of the elbow joint also improved, namely from the Mayo Elbow Performance Score (MEPS) of 65 points to 90 points (from the range of 45-70 points to the range of 80-100 points). In 11 cases (79%) the nonunion was healed and in 3 cases (21%) the failure to heal was reported. In the group with unhealed nonunions, in one case with NUSS of 51-75 points a thermoplastic casting was used and in two patients with NUSS above 76 points a palliative surgery was performed using a 12mm interlocking intramedullary nail. DISCUSSION The results of our study focused on the treatment of aseptic nonunion of the humeral shaft confirm the conclusions arrived at by other authors. As to the osteosynthesis materials, the plate remains the gold standard and provides sufficient stability for bone healing. For unhealed treatment-resistant PSA, we offer a stable intramedullary nail instead of prosthetic replacement or amputation, which provides good stability required for limb function. CONCLUSIONS When planning the treatment of aseptic pseudoarthrosis of the humeral shaft, it is necessary to have a thorough knowledge of etiopathogenesis with all predictive factors. The NUSS classification provides good guidance in treating this complication. Key words: aseptic nonunion, NUSS classification, predictive factors.

PURPOSE: The appropriate treatment of pulseless pink supracondylar humerus fractures (SCHF) remains controversial. In this study, the outcomes of two treatment approaches (with and without vascular surgery) were compared. MATERIAL AND METHODS: This was a retrospective multicenter study of patients with pulseless pink SCHFs treated in ten pediatric surgery, trauma, or orthopedics departments in the Czech and Slovak Republic between 2014 and 2018. RESULTS: Of the total 3608 cases of displaced SCHF, 125 had the pulseless pink SCHF. Of those, 91% (114/125) did not undergo vascular surgery and 9% (11/125) underwent vascular surgery. The patients who did undergo vascular surgery had radial artery pulsation restored more frequently in the operating room (73% vs. 36%; p = 0.02), within 6 h (91% vs. 45%; p = 0.004), and within 24 h of surgery (91% vs. 57%; p = 0.05). However, 72 h after surgery, there was no significant difference in palpable radial artery pulsation between the vascular surgery and the non-vascular surgery groups (91% vs. 74%; p = 0.24). Additionally, no significant differences in long-term neurological (9% vs. 22%; p = 0.46) or circulatory (9% vs. 7%; p = 0.57) deficits were found between the two groups. CONCLUSION: While vascular surgery in patients with pulseless pink SCHFs is associated with a more prompt restoration of radial artery pulsation, no statistical significant differences in terms of the restoration of neurological deficits or the risks of long-term neurological or circulatory deficits were found between patients with and without vascular surgery.
PURPOSE OF THE STUDY Most humeral nonunions can be successfully treated with a single procedure, but some are more difficult to heal. Humeral nonunions which have two or more surgical procedures were defined as refractory humeral nonunions, and this condition is a very challenging condition. The aim of the study is to show the results of atrophic refractory humeral nonunion treated with open reduction and internal fixation and autogenous block iliac crest graft and spongioplasty. MATERIAL AND METHODS Refractory humeral nonunions treated with open reduction and internal fixation and autogenous block iliac crest graft and spongioplasty from January 2010 to March 2019 were included this study retrospectively. Patient baseline information, number of previous surgeries, comorbidities, follow-up time, fracture union time, and complications were recorded. The functional outcome was evaluated with the Constant scores and Mayo scores at the end of the first year. The primary outcome variable was mentioned as bony union. RESULTS A total of 13 refractory humeral nonunions included this study. The average age of the patients was 50.92±15.55 years (range, 26-78 years), and 8 of them were female. Preoperative and postoperative mean Mayo scores were; 56.54±17.84, and 85.38±7.49 respectively (p<0.001). Preoperative and postoperative mean Constant scores were; 45±11.71, and 80.62±5.38 respectively (p<0.001). DISCUSSION The strict application of basic nonunion principles can result in successful salvage of refractory humeral nonunions. But this concept may not provide sufficient solution for each situation. On the other hand, we also applied the basic nonunion principles. Compression plating and autogenous bone grafting and spongioplasty have been considered as the gold standard in the management of humeral shaft nonunion. CONCLUSIONS Open reduction and internal fixation and autogenous block iliac crest graft and spongioplasty should be considered as an alternative for the treatment of refractory atrophic humeral nonunions, whose treatment is a very challenging condition for surgeons. Key words: block graft, bone grafting, nonunion, refractory humeral nonunion, spongioplasty.
