Abstract
PURPOSE Management of fibular hemimelia includes either prosthetic care with or without a suitable amputation or tibial lengthening. Many studies have documented the success of both procedures. Most parents of these children refuse an amputation or have no access to good prosthetic care. The author presents a limb-salvage procedure with tibial lengthening and ankle stabilization. METHODS Twelve children of fibular hemimelia with 14 extremities had been subjected to limb lengthening after lateral leg release. To correct the valgus procurvatum, double oblique diaphyseal osteotomy (DODO) of the tibia was performed in 11 extremities. The age of the patients ranged from two to 15 years with the median of five years. All were male. The proposed procedure included three stages of loosening, lengthening, and stabilization with ankle arthrodesis at a later stage. RESULTS All patients returned for follow-up for the first four years and had been walking on their sensate feet. With DODO followed by fixator/traction could straighten and lengthen the tibia simultaneously and correct the valgus procurvatum. Ankle stabilization provided stability and a plantigrade foot. A follow-up of six to 30 years with a median of ten years has been reported. CONCLUSION A new procedure of loosening, lengthening, and stabilization of the leg with ankle arthrodesis has been proposed. A follow-up of 30 years with a median of ten years of the said procedure has been reported. The procedure provides a long-lasting plantigrade and painless foot that has sensation and proprioception. An amputation at any level has not been recommended.

Song MH, Shin CH, Choi IH, Cho TJ. Characteristics of terminal hemimelia: What is the difference between terminal hemimelia and classic fibular hemimelia? J Child Orthop 2024; 18:179-186. [PMID: 38567037 PMCID: PMC10984148 DOI: 10.1177/18632521241227830] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/05/2023] [Accepted: 12/16/2023] [Indexed: 04/04/2024] Open
Abstract
Purpose Fibular hemimelia has denoted a spectrum of postaxial longitudinal deficiency with fibular aplasia/hypoplasia; the term "terminal hemimelia" is reserved for patients with postaxial longitudinal deficiency having a normal fibula. We aimed to delineate the characteristics of terminal hemimelia. Methods In total, 30 patients with postaxial longitudinal deficiency who had a normal or hypoplastic fibula and visited our institution between 1992 and 2022 were reviewed. Patients were divided into terminal hemimelia and classic fibular hemimelia groups, and their demographic characteristics and clinical and radiographic findings were compared. Results Femoral shortening, knee valgus, and tibial spine hypoplasia were less common in terminal hemimelia (n = 13) than in classic fibular hemimelia (n = 17) (p = 0.03, p < 0.001, and p = 0.003, respectively). None of the patients in the terminal hemimelia group exhibited knee instability, whereas 12% of patients with classic fibular hemimelia did. Ball-and-socket ankle and absence of lateral rays were commonly observed in both groups. However, tarsal coalition was observed less frequently in terminal hemimelia (p = 0.004). All terminal hemimelia patients exhibited a painless plantigrade foot without ankle instability. Despite limb-length discrepancy at maturity averaging 40.4 mm for terminal hemimelia and 67.0 mm for classic fibular hemimelia (p < 0.001), patients with terminal hemimelia, except for one, exhibited > 20 mm of limb-length discrepancy. However, 46% of them underwent limb-length equalization procedures, mostly single-stage tibial lengthening, at a mean age of 11.2 years. Conclusion Terminal hemimelia may present with a milder phenotype than classic fibular hemimelia. It mainly overlaps with the symptoms of fibular hemimelia below the ankle joint and manifests as limb-length discrepancy. However, a considerable number of patients with terminal hemimelia required limb-length equalization procedures, for example single-stage tibial lengthening. Level of evidence level IV.

Abstract
Introduction Foot oligodactyly is usually associated with fibular insufficiency or cleft foot syndrome. A foot with a reduced number of rays may occasionally have an isolated dysplasia. Methods We reviewed the clinical notes and X-rays of six children with oligodactyly, having a normal development of the tibia and fibula. Clinical evaluation recorded the plantigrade or deviated foot, appropriate shoe wear, and aesthetic presentation of barefoot children. Radiological examination revealed missing or hypoplastic bones in the foot, the presence of other deformities, and leg length discrepancy (LLD) of the affected limb. Results On clinical evaluation, all children except one had a plantigrade foot with normal shoe wear; the lesion was not spotted in three of them unless informed of the presence of the dysplasia. Radiological examination in four of them revealed the absence or hypoplasia of the navicular, with a normal shape of the first metatarsal. Calcaneocuboid joints were normal in five of them; LLD was the main problem in three children. The girl with bilateral oligodactyly presented as a normal child. Conclusion Oligodactyly may present as an isolated dysplasia. LLD in these patients, which is less severe than in children with fibular or tibial insufficiency, is the main issue that requires surgical management in later life. Prenatal diagnosis of oligodactyly as an isolated dysplasia is an important feature for appropriate counseling of parents.

Abstract
Introduction The management of tibial hemimelia can be complex and involve either amputation or reconstruction. The decision made carries significant implications on patients and their families. This is a case series in the management of Type IV tibial hemimelia with a description of a novel surgical technique in the reconstructive arm of the pathway. Materials and methods The study included four patients with bilateral tibial hemimelia have an amputation in one limb and reconstructive surgery on the other. The reconstruction involved a supratalar double osteotomy of the tibia and fibula, followed by a staged hindfoot osteotomy using a circular ring fixator. Functional outcomes are reported using the Special Interest Group in Amputee Medicine (SIGAM) and the short form 12 (SF-12) methods. Results The mean age of patients in our cohort is 14 years (3-27 years) with mean age of surgery at 3 years. One case had an amputation following initial reconstructive surgery due to psychological distress and regressive behaviour. SIGAM functional outcome scores of F were recorded in three of four cases, with one patient performing at level B. On the reconstructive side, two of three patients reported a mean physical short form 12 (SF-12) score of 56.7 and a mental SF-12 score of 55.7. One patient reported a physical SF-12 score of 28.5 and a mental SF-12 score of 30.3. Discussion and conclusion A reconstructive option provides a satisfactory functional outcome, comparable to the population mean, in the majority of patients in our cohort. Clinical significance A staged supratalar double osteotomy followed later by a hindfoot osteotomy is effective in centralising the ankle and creates a plantigrade weight-bearing platform for ambulation in patients with Type IV tibial hemimelia.

Abstract
RATIONALE Evaluation of clinical and radiologic abnormalities in patients with postaxial hypoplasia of the lower extremity (PHLE) for treatment decisions represents a major challenge, which is more complicated when PHLE is associated with congenital dislocation of the patella. PATIENT CONCERNS : Herein, we present the case of an 8-year-old female patient with evident length inequality in her left lower extremity and inability to walk. DIAGNOSES Radiological evaluation revealed PHLE with fibular hemimelia, proximal femoral focal deficiency, tarsal coalition, and congenital patellar dislocation of the patella. The right lower extremity was also affected by fibular hemimelia. INTERVENTIONS AND OUTCOMES Surgical management included the Roux-Goldthwait technique for patellofemoral joint realignment, a medial knee stapled with Blount technique, and femur enlargement using the Wagner technique. The results from surgical intervention included a left femoral elongation of 6.7 cm featuring callus with angulation, displacement, and a discrepancy of 5 cm between femurs with a flexor contraction in the knee of -15° and a centralized knee. LESSON PHLE accompanied by congenital dislocation of the patella has not been extensively described in the literature; therefore, there is no established management. Starting reconstruction at an early age, together with an adequate classification of the deformity, are essential factors when opting for limb reconstruction.

Abstract
BACKGROUND Congenital fibular deficiency is a rare disease with a broad spectrum of deformities. Associated anomalies complicate the symptoms of patients and, consequently, individualized treatments that aim at normal function and acceptable appearance. CASE PRESENTATION We present a case of congenital femoral and fibular shortening in the right lower limb with foot anomaly at school age. The patient underwent limb lengthening procedure in a single session on the right femur and tibia at the same time using a double-Ilizarov frame. The functional and cosmetic of his right lower extremity achieved a good outcome. Complications were minimal except for the superficial infection. Treatment lasted for 9.2 months, allowing for returning the patient to functional activity as soon as possible. CONCLUSION A satisfactory result was obtained with limb lengthening in a single session using double Ilizarov external fixators in a school-aged patient with congenital fibular deficiency.

Abstract
Fibular hemimelia (FH) presents with foot and ankle deformity and leg length discrepancy. Many historic reconstructions have resulted in poor outcomes. This report reviews modern classification and reconstruction methods. The Paley SHORDT procedure (SHortening Osteotomy Realignment Distal Tibia) is designed to correct dynamic valgus deformity. The Paley SUPERankle procedure (Systematic Utilitarian Procedure for Extremity Reconstruction) is designed to correct fixed equino-valgus foot deformity. The leg length discrepancy in FH is successfully treated with serial lengthening and epiphysiodesis. Implantable intramedullary lengthening devices have led to all internal lengthenings. Recent advancements in techniques and implants in extramedullary implantable limb lengthening (EMILL) have allowed internal lengthenings in younger and smaller patients, who would traditionally require external fixation. These new internal techniques with lengthenings of up to 5 cm can be repeated more easily and frequently than external fixation, reducing the need to achieve larger single-stage lengthenings (e.g., 8 cm). Modern reconstruction methods with lengthening are able to achieve limb length equalization with a plantigrade-stable foot, resulting in excellent functional result comparable or better than a Syme’s amputation with prosthetic fitting.

Abstract
CASE A total knee arthroplasty (TKA) was performed on a 35-year-old man with congenital fibular deficiency and a 20° varus and 28° antecurvatum tibial deformity of the left lower limb. CONCLUSION One-stage TKA and correction of the extraarticular deformity by means of intraarticular bone resections and a standard soft tissue release were performed to restore the limb's mechanical axis. Patients with congenital fibular deficiency present a wide range of limb deformities because of bone deficiencies or treatment sequels, which might require a specific surgical technique and small-sized implants to obtain good results during a TKA.

Abstract
Anteromedial bowing and shortening of the tibia are intrinsic features of limbs with congenital fibular deficiency (CFD). Tibial bowing occurs more frequently when the fibula is radiographically absent rather than deficient. The bowing has been attributed to rapid longitudinal growth of the tibial anlage coupled with anteromedial tibial bending moments of the posterior crural and lateral peroneal musculature unopposed in the absence of a fibular strut. Eccentric mechanical loading results in asymmetric mineral deposition and thickening of the diaphyseal cortex. Skeletogenesis depends upon an intimate interplay between the normally prefigured tibial cartilage anlage and beginning muscular contractile actions during initial vascularization of the anlage, while the embryonic limb vasculature is undergoing a series of transitions. A diaphyseal periosteal collar normally forms at the site of nutrient artery invasion and stabilizes the growing anlage. In CFD however, arteriography consistently reveals anomalous tibial nutrient arterial branches, which originate from a primitive axial artery rather than from the usual posterior tibial artery. These anomalous nutrient arteries enter the tibial shaft at the posterior aspect of the proximal metaphysis, establishing an eccentric bone collar. The developing vasculature of the embryonic limb is responsive to the then most metabolically active tissues. Disruption of the reciprocal relationship between the transitioning vasculature and the developing long bones is pivotal in producing the diverse skeletal malformations of the congenital short limb (CSL). Embryonic vascular dysgenesis contributes not only to the well-recognized congenital tibial and fibular shortenings but also predisposes to congenital anteromedial bowing of the tibia.

Abstract
PURPOSE Longitudinal fibular deficiency (LFD) is the most common congenital long bone deficiency. This study aimed to objectively assess the physical performance of children and adolescents with LFD compared with unaffected peers, and to examine trends over age for subgroups of the LFD population. METHODS Differences between children with LFD and unaffected peers were examined with hand-held dynamometry for lower-limb muscle strength, Six-Minute Walk Test, Timed up and down stairs test, Star Excursion Balance Test, and Standing long jump. RESULTS Thirty-nine children with LFD and 284 unaffected peers participated. Children with LFD performed at a lower level than their unaffected peers, on all measures of physical performance (mean 2.1 z-scores lower, all p < 0.01), except in long jump (p = 0.27). When comparing the performance of children with LFD to their unaffected peers across four age groups, there was a significant between-groups difference on all strength measures, and on the Six-Minute Walk distance, between children with and without LFD. These differences were smallest in young children (3-6 years) and largest in the older children (15-18 years) (all p < 0.01). Children with no lengthening surgery performed better on the Six-Minute Walk Test, covering a greater distance during the test, than those who had surgery (mean difference 83 metres, p < 0.01). There were no significant differences between children who had or had not undergone an amputation. CONCLUSIONS Children with LFD performed at a significantly lower level than unaffected peers on all measures of physical performance other than jumping. The largest differences were in older children. This paper provides baseline functional data for future interventions in LFD. LEVEL OF EVIDENCE Cross-sectional study.Implications for RehabilitationThis paper provides the first baseline functional data using validated objective measures on a consecutive cohort of children and adolescents with longitudinal fibular deficiency.Children with LFD performed significantly worse than their unaffected peers on all measures of physical performance other than jumping, with children falling further behind their peers as they age.Children who undergo an amputation typically have the most severe anatomical presentation and yet perform at an equivalent functional level.This paper identifies multiple modifiable impairments that represent potential opportunities for rehabilitation professionals to target with conservative treatment options to improve functional performance.

Abstract
PURPOSE Fibula hemimelia is the most common congenital deficiency of long bones. Primary treatment options include amputation with prosthetic fitting or limb reconstruction. The aim of our study was to conduct a systematic review comparing amputation with limb reconstruction for fibula hemimelia. METHODS MEDLINE, EMBASE, Web of Science, Elsevier Scopus, and the Cochrane Registry of Clinical Trials were searched from 1951 to 2019 for studies that evaluated amputation versus limb reconstruction for fibula hemimelia. Random effect models were utilized for the meta-analytic comparisons of amputation versus limb reconstruction for patient satisfaction and surgical complications. Descriptive, quantitative, and qualitative data were extracted. RESULTS Seven retrospective cohort studies were eligible for the meta-analysis, with a total of 169 fibula hemimelia cases. Amputation resulted in an odds ratio of 6.8 (95% confidence interval: 2.4, 19.2) when compared with limb reconstruction in terms of patient satisfaction. Furthermore, limb reconstruction was found to have an odds ratio of 28 (95% confidence interval: 7.8, 100.3) for complications. The total surgical complication rates in the amputation and limb reconstruction groups were 0.2 and 1.2 complications per limb. The rate of surgical procedures per patient was 1.5 and 4.2 for amputation and limb reconstruction, respectively. CONCLUSIONS The cumulative evidence at present indicates better patient satisfaction with less surgical complications and less number of procedures with amputation for fibula hemimelia when compared with limb reconstruction. Absence of uniform protocols make it difficult to compare results accurately. LEVEL OF EVIDENCE Level III-therapeutic.

Abstract
BACKGROUND Patients with congenital fibular deficiency often develop genu valgum secondary to lateral femoral condylar hypoplasia. Guided growth strategies are often performed to correct limb alignment when adequate skeletal growth remains. METHODS A retrospective review of patients with postaxial hypoplasia of the lower extremity managed with an amputation strategy and who had a guided growth procedure for coronal plane limb malalignment during their course of treatment was performed. Clinical and radiographic data, including measures of coronal plane deformity and alignment, type of amputation, subsequent operative procedures, and complications were recorded. RESULTS Seventeen patients (20 extremities) met study inclusion criteria (mean follow-up 8.8 y). Foot ablation and hemiepiphysiodesis for valgus deformity of the knee was performed in all extremities. The average age at the time of initial hemiepiphysiodesis was 11.2 years at an average of 8.8 years from the initial amputation procedure. The mean preoperative mechanical axis deviation was 26.5 mm, which was corrected to a mean mechanical axis deviation of 7.0 mm. Fifteen (75%) of the extremities had correction of the deformity to neutral alignment after the initial procedure. Lack of correction occurred in 3 extremities, and overcorrection occurred in 2 extremities. Additional procedures were required in 5 extremities for rebound valgus deformity after hardware removal. CONCLUSIONS In patients with postaxial hypoplasia, regular monitoring of the residual limb for growth-related changes must occur to ensure optimal function and prosthetic fit. Timing of the guided growth procedure is critical, as younger patients may be more likely to experience rebound deformity. Families and patients should be made aware that growth might be unpredictable in this population with risks of both overcorrection and undercorrection. LEVEL OF EVIDENCE Level IV-case series.

Abstract
Defects occurring in the femoral-fibular-ulnar developmental field are believed to cause the cluster of anomalies seen with femoral, fibular and ulnar limb deficiencies. Upper limb function must be considered in the management of lower limb deficiencies. The purpose of this study is to determine the frequency and type of upper extremity anomalies found in children with femoral and/or fibular deficiency. A retrospective review of 327 consecutive patients with the diagnosis of femoral and/or fibular deficiency was performed using existing records and radiographs. Characteristics of those with and without upper extremity anomalies were compared. Upper extremity anomalies were identified in 56 patients. They were more common among those with bilateral, compared with unilateral, lower extremity deficiencies (P < 0.0001). Seventy-five upper limbs were involved with 50 ulnar deficiencies, nine congenital transhumeral deficiencies, four congenital shoulder disarticulations, seven cleft hands, two radial head dislocations and one each - radial deficiency, syndactyly and capitate-lunate coalition. Two patients with bilateral upper extremity anomalies had ulnar deficiency on one side and a transverse deficiency on the other. Upper extremity anomalies are found in 17% of children with femoral and/or fibular deficiency, especially with bilateral lower extremity involvement. Ulnar deficiency is the most common type but one-third had other anomalies. The frequent finding of congenital transverse upper extremity deficiencies suggests there may be common embryology.

Abstract
Midline metatarsal ray deficiencies, which occur in approximately half of congenital short limbs with fibular deficiency, provide the most distal and compelling manifestation of a fluid spectrum of human lower-extremity congenital long bone reductions; this spectrum syndromically affects the long bone triad of the proximal femur, fibula, and midline metatarsals. The bony deficiencies correspond to sites of rapid embryonic arterial transitioning. Long bones first begin to ossify because of vascular invasions of their respective mesenchymal/cartilage anlagen, proceeding in a proximal-to-distal sequence along the forming embryonic limb. A single-axis artery forms initially in the embryonic lower limb by means of vasculogenesis. Additional arteries evolve in overlapping transitional waves, in proximity to the various anlagen, during the sixth and seventh weeks after fertilization. An adult pattern of vessels presents by the eighth week. Arterial alterations, in the form of retained primitive embryonic vessels and/or reduced absent adult vessels, have been observed clinically at the aforementioned locations where skeletal reductions occur. Persistence of primitive vessels in association with the triad of long bone reductions allows a heuristic estimation of the time, place, and nature of such coupled vascular and bony dysgeneses. Arterial dysgenesis is postulated to have occurred when the developing arterial and skeletal structures were concurrently vulnerable to teratogenic insults because of embryonic arterial instability, a risk factor during arterial transition. It is herein hypothesized that flawed arterial transitions subject the prefigured long bone cartilage models of the rapidly growing limb to the risk of teratogenesis at one or more of the then most rapidly growing sites. Midline metatarsal deficiency forms the keystone of this developmental concept of an error of limb development, which occurs as a consequence of failed completion of the medial portion of the plantar arch. Therefore, the historical nomenclature of congenital long bone deficiencies will benefit from modification from a current reliance on empirical physical taxonomies to a developmental foundation.

Abstract
BACKGROUND Deformity of the tibia, including shortening and angulation, may accompany severe forms of postaxial hypoplasia (fibular deficiency). The current literature reflects varying opinions on the appropriate management for tibial deformity in the setting of fibular deficiency. METHODS We performed a retrospective review to determine outcomes of tibial deformity correction in patients with a primary diagnosis of fibular deficiency. Clinical and radiographic outcomes of patients treated with foot ablation were reviewed to establish indications for tibial deformity correction, identify occurrence of additional surgical procedures related to limb alignment or deformity, and characterize difficulties with prosthetic wear potentially related to residual or recurrent tibial deformity. RESULTS From 1989 to 2016, 51 patients (57 extremities) with fibular deficiency were managed with a foot ablation procedure. Twenty-five (44%) had simultaneous correction of the tibial deformity. The initial tibial deformity measured 42.5 degrees, was corrected to 5.6 degrees intraoperatively, and measured 18.6 degrees at follow-up, suggesting recurrent deformity. In follow-up, approximately half of the patients complained of redness and one third complained of a continued prominence along the anterior tibia. Thirty-two extremities had an isolated foot ablation procedure without tibial osteotomy. Radiographic review demonstrated mild tibial bowing at the time of amputation with a mean angular deformity of 15.4 degrees and remained unchanged during the follow-up period (mean, 12.7 degrees). Similar to the osteotomy group, approximately half of the patients complained of redness and erythema over the anterior bow, with one fourth noting prominence, and only 2 reporting significant pain. CONCLUSIONS Tibial osteotomies in patients with more significant degrees of angular deformity can be safely performed at the same setting as foot ablative procedures for fibular deficiency. Recurrent deformity with growth may occur. Patients and their caregivers should be aware that rebound deformity may occur, but typically can be managed with prosthetic adjustment and without significant disruption to the child's daily activities.

Abstract
The congenital short limb (CSL) with fibular deficiency has traditionally been graded by plain radiography. The most popular orthopedic classification sorts the fibular dysmorphologies into three radiographic groupings: IA (thinned), IB (proximally truncated), or II (absent). In contrast, the soft tissues have been relatively neglected. Since bone formation of the fibula progresses from the anlage, a scaffolding cartilage mold intermediate, cartilage transformation to bone is dependent upon timely embryonic arterial invasion. Absences of the requisite arteries predicate specific skeletal dysmorphologies. The usual arterial supply of the fibula is comprised primarily of the anterior tibialis artery (ATA), which uniquely supplies the proximal portion of the fibula, and also joins the peroneal artery (PA) in supplying the mid to distal fibular shaft. Combinations of the two nutrient arteries allow four potential variations of fibular vascular supply, among which the ATA and PA conjoin to supply the normal fibula and variably supply the three dysmorphic fibular models. The IA and IB deformities conform, respectively, to the absences of the PA and the ATA. Combined ATA and PA absences present in the radiographically "absent" fibula. Thus, each of the four fibular (dys)morphologies conforms to a specific embryonic pattern of arterial development. The term "dystrophism" most accurately characterizes such malformed long bones.

Abstract
BACKGROUND Fibular hemimelia is the most common deficiency involving the long bones. Paley classification is based on the ankle joint morphology, identifies the basic pathology, and helps in planning the surgical management. Reconstruction surgery encompasses foot deformity correction and limb length equalization. The SUPERankle procedure is a combination of bone and soft tissue procedures that stabilizes the foot and addresses all deformities. METHODS We retrospectively reviewed 29 consecutive patients (29 limb segments), surgically treated between December 2000 and December 2014. Among the 29 patients, 27 were treated with reconstructive procedures. Type 1 (8 patients) cases were treated with only limb lengthening, and correction of tibial deformities. Type 2 (7 patients) cases were treated by distal tibial medial hemiepiphysiodesis or supramalleolar varus osteotomy. In type 3 (10 patients) cases, the foot deformity was corrected using the SUPERankle procedure. Type 4 (2 patients) cases were treated with supramalleolar osteotomy along with posteromedial release and lateral column shortening. In a second stage, limb lengthening was performed, using the Ilizarov technique. In the remaining 2 patients (type 3A and type 3C), amputation was performed using Syme technique as a first choice of treatment. RESULTS The results were evaluated using Association for the Study and Application of Methods of Ilizarov scoring. Excellent results were obtained in 15 of 27 (55%) patients. Six (22%) patients had good results, 4 (14.8%) had fair results, and 2 (7%) had poor results. Mean limb length discrepancy at initial presentation was 3.55 cm (range: 2 to 5.5 cm) which significantly improved to 1.01 cm (range: 0 to 3 cm) after treatment (P=0.015). CONCLUSIONS Our results and a review of the literature clearly suggest that limb reconstruction according to Paley classification, is an excellent option in the management of fibular hemimelia. Our 2-staged procedure (SUPERankle procedure followed by limb lengthening) helps in reducing the complications of limb lengthening and incidence of ankle stiffness. Performing the first surgery at an earlier age (below 5 y) plays a significant role in preventing recurrent foot deformities. LEVEL OF EVIDENCE Level IV.

Longitudinal Fibular Deficiency: A Cross-Sectional Study Comparing Lower Limb Function of Children and Young People with That of Unaffected Peers. CHILDREN-BASEL 2019; 6:children6030045.

Abstract
Longitudinal fibular deficiency (LFD), or fibular hemimelia, is congenital partial or complete absence of the fibula. We aimed to compare the lower limb function of children and young people with LFD to that of unaffected peers. A cross-sectional study of Australian children and young people with LFD, and of unaffected peers, was undertaken. Twenty-three (12 males) children and young people with LFD (74% of those eligible) and 213 unaffected peers, all aged 7–21 years were subject to the Knee Osteoarthritis Outcome Score (KOOS/KOOS-Child) and the Cumberland Ankle Instability Tool (CAIT/CAIT-Youth). Linear regression models compared affected children and young people to unaffected peers. Participants with LFD scored lower in both outcomes (adjusted p < 0.05). The difference between participants with LFD and unaffected peers was significantly greater among younger participants than older participants for KOOS activities and sports domain scores (adjusted p ≤ 0.01). Differences in the other KOOS domains (pain/symptoms/quality of life) and ankle function (CAIT scores) were not affected by age (adjusted p ≥ 0.08). Children and young people with LFD on average report reduced lower limb function compared to unaffected peers. Knee-related activities and sports domains appear to be worse in younger children with LFD, and scores in these domains become closer to those of unaffected peers as they become older.

Abstract
To assess the characteristics of ulnar deficiency (UD) and their relationship to lower extremity deficiencies, we retrospectively classified 82 limbs with UD in 62 patients, 55% of whom had femoral, fibular, or combined deficiencies. In general, UD severity classification at one level (elbow, ulna, fingers, thumb/first web space) statistically correlated with similar severity at another. Ours is the first study to show that presence of a lower limb deficiency is associated with less severe UD on the basis of elbow, ulnar, and thumb/first web parameters. This is consistent with the embryological timing of proximal upper extremities developing before the lower extremities.

Abstract
BACKGROUND Fibular hemimelia is the most common congenital long-bone deficiency. It is usually unilateral and results in a limb-length discrepancy. The literature generally subscribes to the concept of constant inhibition, a process by which limb-length ratios between the shorter and longer extremity remain constant throughout growth, but scientific data supporting this concept are sparse. Additionally, recent literature suggests that these children have abnormal skeletal maturation. OBJECTIVE To elucidate the lower-extremity long-bone growth patterns and skeletal maturation of children with unilateral fibular hemimelia. MATERIALS AND METHODS We reviewed medical records of children with unilateral fibular hemimelia seen at a large pediatric hospital over a 17-year period. Inclusion criteria were: at least two scanograms prior to any shortening/lengthening procedure, and no other congenital or acquired disorders. We collected the study cohort's femoral and tibial lengths (scanogram reports), plotted them against patient chronological ages and compared them to published growth standards. When these children's bone ages (Greulich and Pyle) were available, we plotted them against the children's chronological ages. RESULTS Twenty-three children were included (total=115 scanograms). At least 1 bone-age assessment was performed in 19 children (total=84 bone ages). All bone growth curves were within normal growth standards for the femur and tibia. Length ratios between shorter and longer limbs remained constant. Skeletal maturation was within two standard deviations of normal in 90% of bone ages. CONCLUSION Lower-extremity long bones of children with unilateral fibular hemimelia have relatively normal growth curves, supporting and confirming the concept of constant inhibition. Most children show normal skeletal maturation.

Abstract
Background and Aims:There are no population-based studies about hospital admissions and need for surgical treatment of congenital lower-limb deficiencies. The aim is to assess the impact children with lower-limb deficiencies pose to national hospital level health-care system.Materials and Methods:A population-based study was conducted using the national Register of Congenital Malformations and Care Register for Health Care. All 185 live births with lower-limb deficiency (1993–2008) were included. Data on hospital care were collected until 31 December 2009 and compared to data on the whole pediatric population (0.9 million) live born in 1993−2008.Results:The whole pediatric population had annually on average 0.10 hospital admissions and the mean length of in-patient care of 0.3 days per child. The respective figures were 1.5 and 5.6 in terminal lower-limb amputations (n = 7), 1.1 and 3.9 in long-bone deficiencies (n = 53), 0.6 and 1.9 in foot deficiencies (n = 26) and 0.4 and 2.6 in toe deficiencies (n = 101). Orthopedic surgery was performed in 72% (5/7) of patients with terminal amputations, in 62% (33/53) of patients with long bone, in 58% (14/24) of patients with foot and in 25% (25/101) of patients in toe deficiencies. Half (54%) of all procedures were orthopedic operations.Conclusion:In congenital lower-limb deficiencies the need of hospital care and the number of orthopedic procedures is multiple-fold compared to whole pediatric population. The burden to the patient and to the families is markedly increased, especially in children with terminal amputations and long-bone deficiencies of lower limbs.

Abstract
BACKGROUND Absent lateral osseous structures in congenital fibular deficiency, including the distal femur and fibula, have led some authors to refer to the nature of foot ray deficiency as "lateral" as well. Others have suggested that the ray deficiency is in the central portion of the midfoot and forefoot.We sought to determine whether cuboid preservation and/or cuneiform deficiency in the feet of patients with congenital fibular deficiency implied that the ray deficiency is central rather than lateral in patients with congenital fibular deficiency. METHODS We identified all patients with a clinical morphologic diagnosis of congenital fibular deficiency at our institution over a 15-year period. We reviewed the records and radiographs of patients who had radiographs of the feet to allow determination of the number of metatarsals, the presence or absence of a cuboid or calcaneocuboid fusion, the number of cuneiforms present (if possible), and any other osseous abnormalities of the foot. We excluded patients with 5-rayed feet, those who had not had radiographs of the feet, or whose radiographs were not adequate to allow accurate assessment of these radiographic features. We defined the characteristic "lateral (fifth) ray present" if there was a well-developed cuboid or calcaneocuboid coalition with which the lateral-most preserved metatarsal articulated. RESULTS Twenty-six patients with 28 affected feet met radiographic criteria for inclusion in the study. All affected feet had a well-developed cuboid or calcaneocuboid coalition. The lateral-most ray of 25 patients with 26 affected feet articulated with the cuboid or calcaneocuboid coalition. One patient with bilateral fibular deficiency had bilateral partially deficient cuboids, and the lateral-most metatarsal articulated with the medial remnant of the deformed cuboids. Twenty-one of 28 feet with visible cuneiforms had 2 or 1 cuneiform. CONCLUSIONS Although the embryology and pathogenesis of congenital fibular deficiency remain unknown, based on the radiographic features of the feet in this study, congenital fibular deficiency should not be viewed as a global "lateral lower-limb deficiency" nor the foot ray deficiency as "lateral."

Abstract
Amputation is not a defeat or failure of treatment, but an effective management strategy for certain conditions in the pediatric population. The principles of management, especially in the pediatric population, have not changed. Current surgical strategies focus on providing an optimal residual limb for prosthetic fitting. New technology provides improvement in the design and fabrication of prosthetic devices.

Abstract
PURPOSE Complete fibula absence often presents with significant lower-limb deformity. Parental counselling regarding management is paramount in achieving the optimum functional outcome. Amputation offers a single surgical event with minimal complications. This study compares outcomes with an amputation protocol to those using an extension prosthesis. METHOD Thirty-two patients were identified. Nine patients (2 males, 7 females; median age at assessment of 23.5 years) used an extension prosthesis. Twenty-three patients (16 males, 7 females; median age at assessment of eight years) underwent 25 amputations during childhood. Mobility was assessed using SIGAM and K scores. Quality of life was assessed using the PedsQL inventory questionnaire; pain by a verbal severity score. RESULTS The 19 Syme and one Boyd amputation in 19 patients were performed early (mean age 15 months). Four Syme and one trans-tibial amputation in four patients took place in older children (mean age 6.6 years). Only two underwent tibial kyphus correction to aid prosthetic fitting. K scores were significantly higher (mean 4 vs 2) and pain scores lower in the amputation group allowing high impact activity compared with community ambulation with an extension prosthesis. The SIGAM and PedsQL scores were all better in the amputation group, but not significantly so. CONCLUSION Childhood amputation for severe limb length inequality and foot deformity in congenital fibula absence offers excellent short-term functional outcome with prosthetic support. The tibial kyphus does not need routine correction and facilitates prosthetic suspension. Accommodative extension prostheses offer reasonable long-term function but outcome scores are lower.

Abstract
Fibular hemimelia presents with foot deformity and leg length discrepancy. Previous classifications have focused on the degree of fibular deficiency rather than the type of foot deformity. Published methods of surgical reconstruction have often failed due to residual or recurrent foot deformity. The purpose of this report is to introduce new classification and reconstruction methods. The Paley SHORDT procedure is used to stabilize the ankle when there is a hypoplastic distal fibula with a dynamic valgus deformity. It involves shortening and realignment of the distal tibia relative to the fibula. In contrast, the Paley SUPERankle procedure is used when there is a fixed equinovalgus foot deformity. The SUPERankle uses a supramalleolar shortening-realignment osteotomy and/or subtalar osteotomies with anlage resection. Due to the bony instead of soft tissue correction of deformity, residual or recurrent deformity is prevented. Weakening of gastro-soleus and peroneal muscles is avoided by shortening of the tibia instead of tendon lengthening. The limitation of ankle motion is related to ankle dysplasia rather than surgery or lengthening. A plantigrade-stable foot and ankle leads to an excellent functional result comparable or better than a Syme's amputation with prosthetic fitting. Serial lengthening procedures combined with the SHORDT or SUPERankle reconstruction lead to limb length equalization with a plantigrade, painless, functional foot.

Abstract
BACKGROUND Individuals with lower limb amputation (LLA) commonly experience low back pain (LBP). Although massage effects on LBP are well-documented, research regarding massage for individuals with LLA is scarce. OBJECTIVES This study evaluated the effectiveness of massage therapy to promote activity level, decrease LBP, and improve health-related quality of life (HRQOL) in a long-term prosthetic user. METHODS The 50-day study consisted of two baseline sessions, seven treatment sessions that included a 50-min massage applied to major gait muscles, and two follow-up sessions. Pedometer-measured ambulatory activity level, visual analog scale-measured pain level, and RAND-36 Health Survey 1.0-determined HRQOL were assessed. RESULTS Pain level decreased, HRQOL increased, and no change occurred in ambulatory activity level. CONCLUSION For the participant, therapeutic massage intervention lead to successful LBP symptom management.

Abstract
Nineteen foot centralizations were performed in 14 patients with Jones type I and II tibial hemimelia. All feet showed equinovarus deformity and were treated by foot centralization by means of calcaneofibular arthrodesis. The average age of patients at the time of surgery was 1.3 years (range 0.4-3.8 years). The average follow-up postoperative period was 10.2 years (range 2.2-22.9). At the time of the final follow-up, four of the operated feet were plantigrade without secondary surgery. The remaining 15 limbs, however, required secondary surgery to treat postoperative early loss of correction and/or recurrent foot deformities such as equinus, varus and adduction, in addition to talipes calcaneal deformities, and fibular angular deformity at the fibular shortening osteotomy site. The deformities were treated either by repeat foot centralization, or fibular or calcaneal osteotomy. Careful observation for recurrence of the deformity is necessary until the distal fibular epiphysis closes, and the cartilagenous distal fibular end and calcaneus finally achieve ankyloses.

Abstract
BACKGROUND Patients with congenital limb shortening can present with joint instability, soft tissue contractures, and significant leg length discrepancy. Classically, lengthening is done with external fixation, which can result in scarring, pin site infection, loss of motion, and pain. We therefore developed an alternative to this approach, a new, controllable, internal lengthening device for patients with congenital limb shortening. QUESTIONS/PURPOSES We evaluated this device in terms of (1) healing index, (2) complications, (3) accuracy of the device's external controller, and (4) adjacent-joint ROM. METHODS Between January 2012 and May 2013, we treated 66 patients for congenital limb shortening, of whom 21 were treated using this device. During this period, general indications for using the device were patients with leg length discrepancies of 2 cm or more, with intramedullary canals able to withstand rods of at least 12.5-mm diameter and 230-mm length, without active infection in the affected bone, able to comply with the need for frequent lengthening, and without metal allergies or an implanted pacemaker. We included only those patients who had completed their course of treatment and were currently fully weightbearing, leaving 18 patients (21 bone segments) available for followup at a minimum of 6 months after limb lengthening (mean, 14 months; range, 6-22 months). Mean age was 19 years (range, 9-49 years). Sixteen femurs and five tibias were lengthened a mean of 4.4 cm (range, 2.1-6.5 cm). Mean distraction index was 1.0 mm/day (range, 0.5-1.8 mm/day). Healing index, complications, device accuracy, and ROM were recorded. To date, 10 of the 21 devices have been removed. This was typically done 12-24 months after insertion when the bone was solidly healed on all four cortices. RESULTS Mean healing index was 0.91 months/cm (range, 0.2-2.0 months/cm). There were seven complications requiring an additional unplanned surgery, including one hip flexion contracture, three femurs with delayed healing, one tibia with delayed healing, one hip subluxation/dislocation, and one knee subluxation. The external controller was accurate as programmed and actual lengthening amounts were consistent. ROMs of the hip, knee, and ankle were essentially maintained. CONCLUSIONS This device is completely internal, allowing for satisfactory joint motion during treatment in most patients. Lengthening was achieved in an accurate, controlled manner, and all patients reached their goal length. Complications remain a concern, as is the case with all approaches to this complex patient population. Both future comparative studies and longer-term followup are needed. LEVEL OF EVIDENCE Level IV, therapeutic study. See Instructions for Authors for a complete description of levels of evidence.

Abstract
Congenital fibular deficiency (CFD) is characterized by a wide spectrum of manifestations ranging from mild limb length inequality (LLI) to severe shortening, with foot and ankle deformities and associated anomalies. The etiology of CFD remains unclear. Treatment goals are to achieve normal weight bearing, a functional plantigrade foot, and equal limb length. The recent Birch classification system has been proposed to provide a treatment guide: the functionality of the foot, LLI, and associated anomalies should be taken into account for decision-making. Treatment options include orthosis or epiphysiodesis, Syme or Boyd amputation and prosthetic rehabilitation, limb lengthening procedures, and foot and ankle reconstruction. The outcome of amputation for severe forms of CFD has shown favorable results and fewer complications compared with those of limb lengthening. Nevertheless, advances in the limb lengthening techniques may change our approach to treating patients with CFD and might extend the indications for reconstructive procedures to the treatment of severe LLI and foot deformities.

Abstract
The arterial patterns of the lower extremities of three patients with congenital absence fibulae (hemimelia) were evaluated to determine whether the relationship existed between the absence of peroneal artery and hemimelia. Computerized tomograph angiography revealed the absence of peroneal artery in all the patients with dysplastic limbs and absent fibula.

Jaffe-Campanacci syndrome, revisited: detailed clinical and molecular analyses determine whether patients have neurofibromatosis type 1, coincidental manifestations, or a distinct disorder. Genet Med 2013; 16:448-59. [PMID: 24232412 DOI: 10.1038/gim.2013.163] [Citation(s) in RCA: 24] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2013] [Accepted: 09/10/2013] [Indexed: 01/02/2023] Open
Abstract
PURPOSE "Jaffe-Campanacci syndrome" describes the complex of multiple nonossifying fibromas of the long bones, mandibular giant cell lesions, and café-au-lait macules in individuals without neurofibromas. We sought to determine whether Jaffe-Campanacci syndrome is a distinct genetic entity or a variant of neurofibromatosis type 1. METHODS We performed germline NF1, SPRED1, and GNAS1 (exon 8) mutation testing on patients with Jaffe-Campanacci syndrome or Jaffe-Campanacci syndrome-related features. We also performed somatic NF1 mutation testing on nonossifying fibromas and giant cell lesions. RESULTS Pathogenic germline NF1 mutations were identified in 13 of 14 patients with multiple café-au-lait macules and multiple nonossifying fibromas or giant cell lesions ("classical" Jaffe-Campanacci syndrome); all 13 also fulfilled the National Institutes of Health diagnostic criteria for neurofibromatosis type 1. Somatic NF1 mutations were detected in two giant cell lesions but not in two nonossifying fibromas. No SPRED1 or GNAS1 (exon 8) mutations were detected in the seven NF1-negative patients with Jaffe-Campanacci syndrome, nonossifying fibromas, or giant cell lesions. CONCLUSION In this study, the majority of patients with café-au-lait macules and nonossifying fibromas or giant cell lesions harbored a pathogenic germline NF1 mutation, suggesting that many Jaffe-Campanacci syndrome cases may actually have neurofibromatosis type 1. We provide the first proof of specific somatic second-hit mutations affecting NF1 in two giant cell lesions from two unrelated patients, establishing these as neurofibromatosis type 1-associated tumors.

Abstract
The objective of this study is to present treatment of fibular hemimelia along with the complications, results, and an algorithm for treatment indications on the basis of authors' experience. A group of 31 patients was studied. In patients fulfilling the criteria for amputation, Syme's amputation should be performed. Elongation should be performed in case of type IA or IB fibular hemimelia, with a functional foot with more than three rays, leg shortening less than 5 cm at birth, and less than 10 cm at 9 years of life. The combination of epiphysiodesis with elongation produces the best outcome and is best accepted by the patients.

Limb Lengthening and Reconstruction Society AIM index reliably assesses lower limb deformity. Clin Orthop Relat Res 2013; 471:621-7. [PMID: 23054511 PMCID: PMC3549163 DOI: 10.1007/s11999-012-2609-8] [Citation(s) in RCA: 18] [Impact Index Per Article: 1.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/19/2012] [Accepted: 09/07/2012] [Indexed: 01/31/2023]
Abstract
BACKGROUND Although several systems exist for classifying specific limb deformities, there currently are no validated rating scales for evaluating the complexity of general lower limb deformities. Accurate assessment of the complexity of a limb deformity is essential for successful treatment. A committee of the Limb Lengthening and Reconstruction Society (LLRS) therefore developed the LLRS AIM Index to quantify the severity of a broad range of lower extremity deformities in seven domains. QUESTIONS/PURPOSES We addressed two questions: (1) Does the LLRS AIM Index show construct validity by correlating with rankings of case complexity? (2) Does the LLRS AIM Index show sufficient interrater and intrarater reliabilities? METHODS We had eight surgeons evaluate 10 fictionalized patients with various lower limb deformities. First, they ranked the cases from simplest to most complex, and then they rated the cases using the LLRS AIM Index. Two or more weeks later, they rated the cases again. We assessed reliability using the Kendall's W test. RESULTS Raters were consistent in their rankings of case complexity (W = 0.33). Patient rankings also correlated with both sets of LLRS AIM ratings (r(2) = 0.25; r(2) = 0.23). The LLRS AIM Index showed interrater reliability with an intraclass correlation (ICC) of 0.97 for Trial 1 and 0.98 for Trial 2 and intrarater reliability with an ICC of 0.94. The LLRS AIM Index ratings also were highly consistent between the attending surgeons and surgeons-in-training (ICC = 0.91). CONCLUSIONS Our preliminarily observations suggest that the LLRS AIM Index reliably classifies the complexity of lower limb deformities in and between observers.

Abstract
OBJECTIVE Diagnosis of fibular hemimelia is based on the identification of absence or shortening of the fibula in relation to the tibia. Despite the existence of different classifications of this congenital deficiency, certain morphological forms defy proper classification. One such form is absence of foot rays with leg shortening in the presence of an entire fibula. In these cases, foot morphology suggests that central foot rays, not lateral ones, are affected by the deficiency; thus justifying the hypothesis concerning the existence of a separate type of hypoplasia, which may be named "intermediate ray deficiency" (IRD). MATERIALS AND METHODS Nine patients with IRD, with an average age of 9.4 years at diagnosis (2.9-15), were analyzed. Clinical and radiographic parameters of the leg and foot were recorded according to the Stanitski classification of fibular hemimelia. The position of the lateral and medial malleoli was assessed. Axial alignment was analyzed according to the Paley method. RESULTS The number of foot rays in eight cases was 4, while in one case, it was 3. Talocalcaneal synostosis was observed in seven cases. The shape of the ankle joint was spherical in six cases, horizontal in two cases and valgus in one case. The position of the lateral malleolus was slightly higher compared to normal. An average functional leg length discrepancy was 4.4 cm. The average percentage of fibular shortening was 9.5 %, tibial shortening 8.7 % and femoral shortening 3.3 %. In all of the cases, slight knee valgus was observed on the femoral level (average 3.3°) and tibial level (average 2.0°). As a result, criteria for IRD diagnosis were proposed. CONCLUSION "Intermediate ray deficiency" might be defined as a separate type of lower limb hypoplasia.
