PURPOSE: To describe foot abnormalities in proximal femoral focal deficiency and their correlation to the severity. METHODS: Eighty-nine extremities in 87 patients were evaluated between 1996 and 2020 clinically and radiologically. Fibula length, ankle shape, tarsal coalitions, and the number of foot rays were recorded. Extremities with proximal femoral focal deficiency were classified according to Pappas and divided into severe (classes II and V), medium severe (classes III and IV), and mild groups (classes VII, VIII, and IX). RESULTS: The fibula was short in 89% and absent in 11% of cases. An absent fibula occurred mostly in severe class III and only in 4% of mild grades (statistically significant, p = 0.004). The valgus ankle joint prevailed in 82% of cases. Spherical ankle joints (18% of cases) were associated in all cases with a tarsal coalition. Tarsal coalitions occurred in 14.6% and were present in all classes except class IV. Five ray feet were found in 83% of cases, four ray feet were found in 16%, and three ray feet in one extremity. Reduction in the number of foot rays occurred more commonly in association with fibular aplasia (30%). CONCLUSIONS: Abnormalities of the fibula and ankle joint represent a constant part of proximal femoral focal deficiency, whereas tarsal coalition and a reduction of foot rays do not. The severity of foot abnormalities does not correlate to the severity of proximal femoral focal deficiency but does with fibular aplasia.

PURPOSE: To evaluate the effect of vitamin D on the speed and quality of pediatric fracture healing. METHODS: A 4-year prospective study of healthy children with shaft fractures of the forearm bones (treated with minimally invasive osteosynthesis) or femur (treated by traction or by minimally invasive osteosynthesis). All children had their vitamin D levels examined four times-at the time of the injury, 1, 3, and 5 months after the injury. Also, all children underwent radiograph follow-ups (same time as blood tests) to evaluate fracture healing. Children were, in the beginning, blindly divided into two similarly sized groups-one group was orally administered cholecalciferol throughout the follow-up, the second group was not, and we compared those groups. RESULTS: Altogether, 63 children were included in the study-36 supplemented and 27 non-supplemented. In supplemented children, the vitamin D levels increased statistically significantly during the follow-up period, in contrast to the non-supplemented group. The fracture healing on radiographs was also statistically significantly faster and better in the supplemented group. When we divided children according to fracture type, we observed statistically significantly better fracture healing in children with forearm fractures in the supplemented group for the whole study period. In children with femoral fractures, the healing in the supplemented group was statistically significantly better after 3 months; however, after 1 and 5 months, the difference was not statistically significant. CONCLUSIONS: Based on our results, we recommend vitamin D testing and administration for children treated for forearm and femoral fractures. LEVEL OF EVIDENCE: Level I.

PURPOSE: The aim of the study is to evaluate the use of ultrasound imaging in diagnostics of Monteggia lesion in children where conventional radiographs and the use of the radiocapitellar line fail to provide an accurate diagnosis. METHODS: Prospective diagnostic study of 70 patients treated between May 2018 and July 2021 in a pediatric level 1 trauma center. In 20 patients with the confirmed radiographic diagnosis of Monteggia lesion, an ultrasound of the humeroradial joint was performed to determine signs of both normal and dislocated elbow joint. In 36 patients with suspected humeroradial dislocation on plain radiographs, ultrasound imaging was performed to determine the definitive diagnosis. Overall, 14 patients with elbow joint injury other than humeroradial dislocation were excluded from the study. RESULTS: The "double-hump sign" and the "congruency sign" were determined as normal findings on ultrasound of the humeroradial joint. These signs were applied to patients with unclear findings on radiographs. In three patients, the dislocation of the humeroradial joint was confirmed by ultrasound. In two patients, "defect in congruency sign" was seen during reduction despite normal radiographs, which required re-reduction. In 31 patients, dislocation of the humeroradial joint was refuted. In 34 out of the 36 patients, the diagnosis determined by ultrasound was confirmed in follow-up. Two patients did not attend the follow-up examination. CONCLUSION: Ultrasound imaging is an accessible, non-invasive, and dynamic point-of-care method that can be applied in children suffering from suspected humeroradial dislocation and/or subluxation. LEVEL OF EVIDENCE: Level III-diagnostic study.

PURPOSE: The goal of this retrospective study was to compare the gradual lengthening of the ulna in children with multiple hereditary exostoses with and without an elastic intramedullary nail. METHODS: Between 1998 to 2018, the ulna was lengthened in 28 forearms in 21 patients (aged 7.1 to 16.6 years) using a monolateral external fixator when relative ulnar shortening exceeded 15 mm. In total, 16 forearms were lengthened with the external fixator (group I) and 12 forearms with the addition of an intramedullary elastic nail (group II). Subjective assessment of function, range of movement (ROM) of the wrist and elbow and complications were compared. Ulnar shortening, radial head dislocation, radial articular angle (RAA) and percentage of carpal slip and radial bowing were followed radiographically. The difference between the groups has been evaluated statistically. RESULTS: The function of the extremity improved partially in 81% of patients in group I and in 83% of patients in group II. ROM was not improved except for radial deviation. Radial head position did not change. The values in group II in comparison with group I are higher for gain of length and lower for bone lengthening index and for bone healing index. Carpal slip decreased insignificantly. The RAA and radial bowing decreased, the comparison of values between groups and age under and over ten years were not statistically significant. Complications were more common in group I. No permanent complications were noted. CONCLUSION: The addition of an intramedullary nail during the gradual ulnar lengthening improves the gain, bone healing index and rate of complications. LEVEL OF EVIDENCE: III.

PURPOSE: The anatomy and neurovascular supply of the pectoralis major muscle was studied in order to establish the safe and functional muscle transfer for the reconstruction of elbow flexion in patients with arthrogryposis multiplex congenita (AMC). METHODS: Twenty pectoralis major muscles were dissected in 11 adult cadavers. The distribution of the motor end plates was studied in five pectoralis major muscles in foetuses by the detection of esterases. RESULTS: The pectoralis major muscle consists of clavicular, manubrial, sternocostal, costal and abdominal parts. Each part has a distinct vascular and nerve supply. The motor nerves arise from the medial and lateral pectoral nerves. The motor end plates are localised in one zone in the clavicular and manubrial parts and in two oblique zones in the distal parts of the muscle. In 15 cases, each of the muscle parts were supplied by one nerve branch. In four cases, six nerves were distinguished and the clavicular part was supplied by two nerves. In one case, four nerves were found, with the clavicular and manubrial parts supplied by one common nerve. Three branches (13 cases) or two arterial branches (seven cases) supplied the muscle, arising from thoracoacromial and lateral thoracic arteries, respectively. The superior branch supplied the clavicular and manubrial parts, whereas the dominant pectoral branch supplied the manubrial, sternocostal and costal parts of the muscle. The inferior branch of the lateral thoracic artery supplied the abdominal part in 13 cases. In seven cases, the inferior branch failed and the abdominal part was supplied from the dominant branch. CONCLUSION: This study presents guidelines for the transfer of the distal parts of the pectoralis major muscle for the reconstruction of elbow flexion. The sternocostal, costal and abdominal parts of the muscle can be released as a unit from the chest wall after dissection between the second and third rib and be transferred to the brachium. They are sufficiently supplied from the dominant pectoral branch of the thoracoacromial artery in all cases and inconstantly from the inferior branch of the lateral thoracic artery and from three motor nerves.

PURPOSE: Acute tibial tubercle avulsion fractures typically occur in adolescent boys involved in certain sports. All of the excerpted authors recommend open reduction and internal fixation (ORIF) as the only method to manage the displaced form of the injury. We attempted to select the optimal medical treatment of various types of this injury. The closed reduction and internal fixation (CRIF) method was selectively used. METHODS: During a period of 10 years (1997-2006), we treated 12 children with an acute injury to the tibial tubercle. Ogden's classification was used to describe the type of injury. Nine patients with a displaced fracture were treated surgically, using either the CRIF or ORIF methods. In cases of intraarticular fracture, the use of the CRIF method was tested. The suitability of the CRIF method was decided during manipulation of the fragments under an X-ray amplifier. RESULTS: According to Ogden's classification, three children were classified with type 1A, one with 1B, three with 2A, four with 3A, and one with 3B. In patients with the displaced extraarticular injury (types 1B and 2A), the ORIF method of treatment was necessary. In all but one case of intraarticular fracture (type 3A and 3B), the CRIF method was sufficient. CONCLUSIONS: The authors recommend that, for displaced intraarticular Ogden's type 3A or 3B fracture, the CRIF method should be considered as a first choice.
