RESUMO
BACKGROUND AND PURPOSE: Bilateral femoral distraction osteogenesis in patients with achondroplasia is insufficiently reported. We aimed to perform the first study that exclusively analyzed simultaneous bilateral femoral distraction osteogenesis with motorized intramedullary lengthening nails via an antegrade approach in patients with achondroplasia focused on reliability, accuracy, precision, and the evolving complications. PATIENTS AND METHODS: In this retrospective singlecenter study we analyzed patients with achondroplasia who underwent simultaneous bilateral femoral lengthening with antegrade intramedullary lengthening nails between October 2014 and April 2019. 15 patients (30 femoral segments) of median age 14 years (interquartile range [IQR] 12-15) were available for analysis. The median follow-up was 29 months (IQR 27-37) after nail implantation. RESULTS: The median distraction length per segment was 49 mm (IQR 47-51) with a median distraction index of 1.0 mm/day (IQR 0.9-1.0), and a median consolidation index of 20 days/cm (IQR 17-23). Reliability of the lengthening nails was 97% and their calculated accuracy and precision were 96% and 95%, respectively. The most common complication was temporary restriction of knee range of motion during distraction in 10 of 30 of the lengthened segments. 1 patient was treated with 2 unplanned additional surgeries due to premature consolidation. CONCLUSION: The method is reliable and accurate with few complications.

BACKGROUND: In the treatment of tall stature, the reduction of excessive predicted final height can either be achieved by hormonal treatment or surgically by temporary (tED) or permanent (pED) epiphysiodesis. The present study evaluates the preliminary results of two novel devices for tED and pED around the knee to reduce the predicted final height. MATERIALS AND METHODS: A retrospective analysis was performed to evaluate the clinical and radiographic outcome after bilateral epiphysiodesis for the treatment of tall stature. A cohort of 34 patients (16 girls, 18 boys) who underwent either tED or pED between 2015 and 2020 were eligible for analysis based on the electronic patient records and picture archiving and communication system of our orthopaedic teaching hospital. tED was conducted in 11 patients (32%) through bilateral implantation of four RigidTacks™ (Merete, Berlin, Germany) around the knee. Twenty-three patients (68%) received pED, performed with an EpiStop™ trephine (Eberle, Wurmberg, Germany). The mean overall follow-up time was 2.9 years. RESULTS: The mean age at surgery was 12.3 years in girls and 13.2 years in boys. Patients had a mean body height of 175.2 cm in girls and 184.7 cm in boys at surgery. The mean predicted final height was 191.4 cm in girls and 210.4 cm in boys. At the last follow-up, 26 patients (76.5%) had achieved skeletal maturity. The mean height of skeletally mature patients was 187.2 cm in girls and 198.5 cm in boys. A mean reduction of the predicted final height of 5.9 cm in girls and 8.7 cm in boys was achieved, corresponding to a reduction in remaining growth of 46% in girls and 38% in boys. Secondary frontal plane deformities of the knee were detected in 5/11 patients (45.5%) in the tED group and 1/23 treatments (4.3%) in the pED group. CONCLUSIONS: tED and pED have both proven to be efficient at achieving growth inhibition to reduce excessive predicted height. However, tED has been associated with an increased risk of secondary angular deformities of the knee. Furthermore, the risk of implant-related complications and the necessity of a subsequent surgical intervention for implant removal have led our study group to abandon tED when treating tall stature. Long-term results of both procedures are pending.

We aimed to evaluate the functional outcome and endoprosthetic complications following the Bateman-type soft tissue reconstruction around proximal or total humeral replacements in patients undergoing resection of a primary malignant bone tumor. Between September 2001 and December 2018, a total of 102 patients underwent resection of a primary malignant bone tumor and subsequent reconstruction with a modular humeral megaprosthesis in our department. Fifteen (15%) of these patients underwent a Bateman-type soft tissue reconstruction and were included in this retrospective study. The median Musculoskeletal Tumor Society (MSTS) score was 21, the median Toronto Extremity Salvage Score (TESS) was 70, and the median American Shoulder and Elbow Surgeons (ASES) score was 72. Fifty-three percent (8/15) of all patients required a revision surgery after a median time of 6 months. There were 2 soft tissue failures, 3 infections and 3 tumor recurrences. The revision-free implant survivorship amounted to 53% (95% confidence interval (CI) 28-81) after 1 year and 47% (95% CI 22-73) at last follow-up. The Bateman-type reconstruction is a feasible option for soft tissue reconstruction but functional outcome is overall limited and the risk for revision surgery within the first postoperative year is high.
RESUMO
Background and purpose - Van Neck-Odelberg disease (VND) is a self-limiting skeletal phenomenon characterized by a symptomatic or asymptomatic uni- or bilateral overgrowth of the pre-pubescent ischiopubic synchondrosis. It is frequently misinterpreted as a neoplastic, traumatic, or infectious process, often resulting in excessive diagnostic and therapeutic measures. This study assessed the demographic, clinical, and radiographic features of the condition and analyzed diagnostic and therapeutic pathways in a large single-center cohort.Patients and methods - We retrospectively analyzed 21 consecutive patients (13 male) with a median age of 10 years (IQR 8-13) and a median follow-up of 5 years (IQR 42-94 months), who were diagnosed at our department between 1995 and 2019.Results - VND was unilateral in 17 cases and bilateral in 4 cases. Initial referral diagnoses included suspected primary bone tumor (n = 9), fracture (n = 3), osteomyelitis (n = 2), and metastasis (n = 1). The referral diagnosis was more likely to be VND in asymptomatic than symptomatic patients (4/6 vs. 2/15). More MRI scans were performed in unilateral than bilateral VND (median 2 vs. 0). All 15 symptomatic patients underwent nonoperative treatment and reported a resolution of symptoms and return to physical activity after a median time of 5 months (IQR 0-6).Interpretation - By understanding the physiological course of VND during skeletal maturation, unnecessary diagnostic and therapeutic measures can be avoided and uncertainty and anxiety amongst affected patients, their families, and treating physicians can be minimized.

PURPOSE: The aim of this study was to evaluate the success of guided growth by temporal hemiepiphysiodesis of the lateral proximal tibia as a first line treatment option for Blount disease. METHODS: This was a retrospective multicentre study conducted in five centres, covering data on 55 limbs in 45 patients, with an average follow-up of 24.5 months following plate insertion. Preoperative alignment analysis was compared with three measurements taken postoperatively. The normalization of the mechanical medial proximal tibia angle (mMPTA) was defined as the primary outcome measure. RESULTS: Mean age at surgery was 9.5 years. Average preoperative mMPTA was 77°. On average, at 24.5 months post-surgery, mMPTA was 86.33°, while 43/55 limbs (78.18%) have achieved normalization (mMPTA 85° to 90°). Average rate of correction was 1° per month. When grouping the children as infantile (11 limbs), juvenile (12 limbs) and adolescent (32 limbs), operated on before the age of four years, between four and ten years and after the age of ten years, respectively, 63.63%, 66.67%, 87.5% have completed correction of deformity during the follow-up period. Interestingly, the femoral component of the deformity has achieved correction as well in 33/55 limbs (64%). CONCLUSION: Hemiepiphysiodesis is an effective first line treatment for Blount disease. Overall success rate is good but varies according to child's age. Adolescent Blount has the best chance of achieving full correction while same treatment is less effective in infantile Blount.Level of evidence: IV.
RESUMO
AIM: Presentation of the joint angle tool (JAT), a low-cost goniometer for intraoperative assessment of the lower limb alignment. BACKGROUND: Intraoperative assessment of coronal alignment is important when performing corrective osteotomies around the knee and ankle, limb lengthening, and trauma surgery. JAT provides surgeons with information about the anatomic and mechanical axes intraoperatively based on true anteroposterior radiographs. TECHNIQUE: JAT consists of pre-printed joint orientation angles of the anatomic and mechanical axis including normal variations on a plastic sheet. It is placed on the screen of the image intensifier after obtaining a true anteroposterior image. The pre-printed joint orientation angles can assist the surgeons intraoperatively in achieving the pre-planned axis correction. Here, its feasibility is demonstrated in four cases. CONCLUSION AND CLINICAL SIGNIFICANCE: JAT is a modified goniometer that allows intraoperative assessment of the mechanical and anatomic axis. JAT is applicable throughout the entire surgical procedure irrespective of the method of internal fixation and may provide additional reassurance of correct alignment. JAT consists of a plastic sheet with printed joint orientation angles and their normal variation.

RESUMO
OBJECTIVE: Distraction osteogenesis is a method of stimulating the growth of new bone tissue in order to lengthen the extremities or bridge resected bone defects. In addition to the now-established intramedullary procedures, two different fixator systems are in use. The present study investigated the classical Ilizarov ring fixator (IRF) and a hexapod to assess the precision of lower-leg lengthening and complications classified using the Paley criteria for problems, obstacles, and complications. The study also examined the follow-up results in functional tests to assess outcomes in terms of range of motion in adjacent joints, daily activities, and quality of life. PATIENTS AND METHODS: A total of 43 patients (53 segments) who were treated over a period of 16 years were re-assessed. In 33 segments, treatment was carried out with the hexapod Taylor Spatial Frame (TSF); the conventional IRF was used in 20 segments. The patients' mean age was 13.5 years (range 2-54 years). The follow-up examinations were carried out 2-15 years postoperatively and comprised measurement of a current leg axis view with the patient standing, calculation of a knee score, activity scores, ankle joint scores, and assessment of motor function and sensory function using appropriate scores in the lower leg and foot. The post-treatment health-related quality of life was assessed using the Short-Form Health Survey-36 questionnaire. RESULTS: Using the Paley criteria, far fewer problems occurred in the TSF group in comparison with the IRF (TSF 12.1%, IRF 50%). In the problems category, significant differences were observed with regard to axial deviation (TSF 0%, IRF 36.8%) and pin infections (TSF 9.1%, IRF 40%). Comparison of the obstacles and complications did not identify any significant differences between the two groups. Analysis of the scores for the knee, activity, and motor function/sensory function also did not show any marked discrepancies, apart from a major difference in mobility in the upper and lower ankle joints with poorer findings in the TSF group. CONCLUSIONS: During treatment, the TSF ring fixator leads to fewer problems, fewer secondary axial translations, and fewer pin infections. However, with temporary transfixation of the ankle joints, the TSF system is also associated with postoperative deterioration in mobility in the upper and lower ankle joint.
RESUMO
BACKGROUND: The quality of the abstracts presented at a conference reflects the scientific work and level of activity of the scientific association concerned. The aim of the present study was to determine the rate of publications of podium presentations and posters at the conferences of the European Paediatric Orthopaedic Society (EPOS) from 2006 to 2008 and to identify factors that favor publication in peer-reviewed journals. The results are compared with those of other international societies. METHODS: All 646 abstracts (including podiums, posters, and e-posters) presented at the EPOS conferences were investigated using the PubMed database to identify any corresponding published articles in the journals listed in the database. A period of 5 years before and after the relevant conference was used for the PubMed search. Factors influencing publication and the quality of the study, such as the type of presentation and the level of evidence, were also investigated. RESULTS: A publication rate of 36.7% was observed, corresponding to 237 publications of 646 abstracts. The period to publication showed a mean of 13.88 ± 1.34 months. It was found that abstracts of podium presentations were published significantly more often than poster abstracts (P<0.001). Experimental studies, with a publication rate of 50.9%, showed better results than clinical studies (36.0%). Overall, the articles were published in 61 different journals, with the largest number (n=50) appearing in the Journal of Pediatric Orthopaedics. In addition, the present study shows that abstracts with a higher level of evidence were associated with a higher publication rate. CONCLUSIONS: At 36.7%, the rate of publication of EPOS abstracts is within the range reached by other specialist orthopaedics societies, such as the German Society of Orthopaedics and Trauma Surgery (36%) and the British Orthopaedic Association (36%). However, it is lower than the publication rate of the Pediatric Orthopaedic Society of North America (POSNA), at 50%. The high percentage of unpublished conference abstracts (63%), which did not go through a peer-reviewed process, casts doubts upon the practice of utilizing the citation of abstracts based purely on conference abstracts. LEVEL OF EVIDENCE: Statistical study.

Parents of children suffering from disproportionate short stature due to achondroplasia may wish to have surgical leg lengthening carried out for the child. The aim is not to increase height, but rather to achieve physiological proportions in the body. In a systematic review of the literature on the topic dating from the last 20 years, the surgical approaches used for this purpose were analyzed in accordance with the Preferred reporting items for systematic reviews and meta-analyses (PRISMA) criteria. Twelve studies show that to date, involvement of the child in decision-making at the start of treatment has been expected and that it is recommended from the age of 12. In highly heterogeneous patient groups, with varying factors involved and different techniques being used, lengthening (often by more than 10 cm) is described. High complication rates are reported, with many setbacks often requiring repeat surgery. Using PALEY'S multiplier method, the expected standing height, sitting height, and leg length can be predicted and an individualized treatment approach can be planned and operative procedures could be started in early childhood as PERETTI suggests. As the patients are unable to be involved in decision-making as young children, these data may provide a basis for offering differentiated advice to parents, who usually consult a pediatric orthopedist at a very early stage in the child's life.

BACKGROUND AND OBJECTIVES: We present a large study of patients with proximal fibula resection. Moreover we describe a new classification system for tumour resection of the proximal fibula independent of the tumour differentiation. METHODS: In 57 patients the functional and clinical outcomes were evaluated. The follow-up ranged between six months and 22.2 years (median 7.2 years). The indication for surgery was benign tumours in ten cases and malignant tumours in 47 cases. In 13 of 45 patients, where a resection of the lateral ligament complex was done, knee instability occurred. In 32 patients a resection of the peroneal nerve with resulting peroneal palsy was necessary. RESULTS: Patients with peroneal resection had significantly worse functional outcome than patients without peroneal resection. An ankle foot orthosis was tolerated well by these patients. Three of four patients with pathological tibia fracture had local radiation therapy. There was no higher risk of tibia fracture in patients with partial tibial resection. CONCLUSIONS: Resection of tumours in the proximal fibula can cause knee instability, peroneal palsy and in cases of local radiation therapy, a higher risk of delayed wound healing and fracture. Despite the risks of proximal fibula resection, good functional results can be achieved.

INTRODUCTION: Intraligamentary correctional operations like a high tibial osteotomy were performed in genua valga to prevent later medial gonarthrosis especially in younger patients. An unwanted effect of this method seems to be the inferiorization of the patella. This is feared because of the complications in case of subsequent alloarthroplasty. Besides the classical Coventry method as a subtractive osteotomy the hemicallotasis has been established as a sustainable additive procedure. This means a gradual open wedge correction using an external fixateur. OBJECTIVE: The aim of this study was to determine the position of the patella pre- and postoperatively and in follow-ups with subtractive versus additive intraligamentary high tibial osteotomies on the basis of five radiological parameters. It was expected that an additive osteotomy leads to an inferiorized patella position whereas a subtractive osteotomy leads postoperative to a higher position of the tibia. METHOD: Between 1990 and 2001, 54 patients (61 legs) had undergone an operation due to a genu varum either by the subtractive osteotomy (n = 30) according to Coventry's method or the additive gradually hemicallotasis (n = 31) with an external fixator. RESULTS: In coherence with the Coventry's osteotomy a significant inferiorization of the postoperative patella position with all five radiological parameters was observed, the hemicallotasis showed no operation-related significant alteration of the patella height. Instancing the Insall-Salvati Index there were four (12.9%) preoperative and three (9.7%) postoperative patella baja positions detected. Along with the subtractive osteotomy there were 5 preoperative patellae baja (16.7%) and 11 postoperative patellae baja (36.7%) positions. Furthermore a significant interrelation was noticed between the extent of the correctional angle and the postoperative alteration of the patella. CONCLUSION: The results are surprising, contrary was expected. First this can be explained by its gradual, additive correctional property in contrast to the spontaneous correction by the conventional method according to Coventry, second by the postoperative treatment, which allows an early mobilization and active remedial gymnastics, provided an impact resistant osteosynthesis by a fixateur externe is given. In the case of the additive hemicallotasis an intraligamentary osteotomy is recommended. Technically expensive step cuts in order to osteotomize below the tuberositas tibiae are not necessary. Due to the low quota of complications and the small operative expense the continuous distraction is preferential to ad hoc correction. A postoperative patella baja position has not to be afraid in hemicallotasis.

UNLABELLED: Limb-lengthening procedures include a series of radiographic examinations to follow the lengthening process and callus formation. We quantified ionizing radiation exposure during lengthening treatment and estimated the risks associated with this exposure in 53 patients undergoing lengthening procedures. Field size and tube voltage of all radiographs and fluoroscopy time during surgery were recorded. According to conversion factor tables of organ doses, the cumulative organ dose was estimated. Location of lengthening, age, complications during lengthening procedure, range of lengthening, healing index, and other factors affecting the duration of the lengthening procedures were analyzed. Average lengthening was 4.8 cm (range, 3.0-12.5 cm). The average cumulative organ dose for a straight lengthening procedure was 3.1 mSv (range, 0.2-12.5 mSv). The average organ dose per centimeter of lengthening was 0.7 mSv/cm (range, 0.03-5.9 mSv/cm). Doses for patients with tibial lengthening (0.3 mSv/cm) were less than doses for patients with femoral lengthening (1.1 mSv/cm). Age, complications, range of lengthening, and healing index did not influence the dosage of radiation per centimeter lengthening. We judge the average patient's exposure during a limb-lengthening procedure as tolerable, but femur lengthening results in a higher cumulative organ dose. LEVEL OF EVIDENCE: Level II, prognostic study. See the Guidelines for Authors for a complete description of levels of evidence.

Four patients were treated with limb lengthening to correct a leg-length discrepancy that developed after a hip transposition after pelvic resection for sacroma of the pelvis. Three patients had Ewing's sacroma and one patient had osteosarcoma. All patients received chemotherapy; radiotherapy also was administered to the three patients with Ewing's sacroma. Femur lengthening was started at an average of 5.7 years (range, 4.4-6.8 years) after tumor surgery. At the start of elongation, the average age of the patients was 17.3 years (range, 10.3-20.8 years). The average leg-length discrepancy was 10.3 cm (range, 6-12 cm). The average of achieved lengthening was 6.4 cm (range 6-7.5 cm). The average healing index was 32 days (range, 27-40 days) per 1-cm elongation. According to the classification of Paley, two problems and two minor complications were treated by additional interventions. At the final followup, the average functional score was 22 (73%) according to the system of the Musculoskeletal Tumor Society. Leg-length discrepancy after hip transposition can be corrected with distraction osteogenesis. All patients who wore a stiff ankle-foot orthosis before lengthening wore an ordinary shoe lift after lengthening. The problems of the lengthening procedure are similar to the general complication rate of bone lengthening. Because the 5-year survival after resection of a pelvic sarcoma is only 20% to 30%, leg lengthening after hip transposition should be offered only to long-term survivors with at least 5 years event-free survival.

BACKGROUND AND OBJECTIVES: Local therapy of pelvic Ewing's sarcoma remains a challenge because of the complex anatomy and large tumor volumes. Wide resections often end up contaminated with marginal margins in one part of the specimen. Pelvic tumor surgery causes considerable disability, because of the loss of hip function. This may cause a low quality of life for tumor survivors. The aim of the study was to evaluate the oncologic results of combined surgery and radiotherapy of pelvic Ewing's sarcoma. Functional and psychosocial outcome of the tumor survivors was assessed. METHODS: Thirty-six pelvic Ewing's sarcoma patients were treated surgically for local tumor control between 1986 and 1996. Chemotherapy was administered according to current European Intergroup/Cooperative Ewing's Sarcoma Study (EI/CESS) protocols. Radiotherapy was also performed on all patients. All patients were intended to get wide tumor excision and a limb salvage procedure. Complications necessitating operative revision were analyzed and functional results were scored according to the criteria of the Musculoskeletal Tumor Society (MSTS). Quality of life and psychosocial functioning was assessed by the QLQ-C 30 of the European Organization for Research and Treatment of Cancer (EORTC). RESULTS: The overall 5- and 10-year survival rate was 45%. The prognosis of patients with primary metastases was 33%. There were two local recurrences after marginal resection. Every second patient needed at least one surgical revision. A secondary hindquarter amputation was avoided in all patients. MSTS functional evaluation instruments reached 59% (+/-21.0%). Global quality of life of the QLQ-C 30 showed good results (70 +/- 16%) compared to the general population (75 +/- 24%). CONCLUSIONS: The advantages of surgical local control of pelvic Ewing's sarcoma should be offered to the patient. Quality of life measurement after internal hemipelvectomy shows that the life of these patients is more than worth living and that they are able to compensate the functional impairment.

The incidence and characteristics of sacral infiltration in pelvic sarcomas were analyzed. Fifty-one patients with a pelvic sarcoma (chondrosarcoma, 15 patients; Ewing's sarcoma, 23 patients; and osteosarcoma, 13 patients) abutting the sacroiliac joint had surgical treatment. Tumor infiltration into the sacrum was suspected based on preoperative images in 18 patients; 15 of 18 patients had histologic tumor invasion. There was a significant difference of median volume of sarcomas with and without infiltration. One of 23 Ewing's sarcomas, seven of 15 chondrosarcomas, and seven of 13 osteosarcomas penetrated the sacroiliac joint into the sacrum. Logistic regression test showed that diagnosis was the most important factor influencing sacral infiltration. Twelve tumors infiltrated through the posterior part of the joint, two tumors infiltrated through the anterior part, and one large tumor infiltrated through an unknown route. To obtain wide surgical margins, patients at risk (elderly, large tumor, or diagnosis of osteosarcoma or chondrosarcoma) for sacral involvement may require extended internal hemipelvectomy with the medial margin extending into the sacrum. High quality imaging studies should be used to assess the need for transarticular resection.

The intraarticular infiltration of sarcomas around the shoulder was analyzed. Of 58 sarcomas located around the shoulder, which were treated between 1993 and 1998, 15 osteosarcomas, 12 chondrosarcomas, and one Ewing's sarcoma that abutted the shoulder were selected. Radiologic images of 28 tumors were analyzed and compared with pathologic examinations. In 17 of 28 sarcomas (15 in the proximal humerus and two in the scapula), joint infiltration was suspected radiologically because of the existence of a tumor mass probably inside the joint or disruption of the joint surface and protrusion of the tumor. Seven of 17 tumors with radiologically positive and zero of 11 tumors with radiologically negative findings showed histologically positive findings for tumor inside the joint. Four of 11 osteosarcomas and three of four chondrosarcomas of the proximal humerus showed histologic findings of joint infiltration. Pericapsular extension was seen in two patients, direct articular spread with a pathologic fracture was seen in two patients, direct articular spread was seen in one patient, direct articular spread with pericapsular extension was seen in one patient, and pericapsular extension with a pathologic fracture was seen in one patient. The current study showed that pericapsular or direct articular infiltration into the glenohumeral joint is a phenomenon in sarcoma around the shoulder. Exact assessment of tumor existence inside the joint can be difficult in osteosarcoma and chondrosarcoma, so abnormal radiologic findings should be regarded as proof of existence of tumor, and extraarticular wide resection should be planned.

We assessed the long-term results in 22 patients with rotationplasty after resection of high-grade malignant bone tumors. We used established methods (QLQ-C 30; FLZ) to evaluate the quality of life, diplomas, life-contentment, occupational situation and marriage status. After 10-year follow-up, we found no reduction in psychosocial adaptation, and life contentment was about the same as in healthy persons. We therefore recommend rotationplasty instead of amputation whenever conventional limb salvage is impossible.
