Abstract
OBJECTIVE Describe the unusual complication of lower extremity compartment syndrome occurring in an adolescent with spinal cord injury (SCI). METHODS Case presentation. RESULTS A 17-year-old male with C5 ASIA A complete SCI developed a compartment syndrome of his lower leg on the ninth day postinjury. Presenting signs included an equinus deformity of the foot, blackened induration over the anterior tibia, circumferential erythematous markings over the calf, large urticarial lesions over the knee, and calf swelling. The presumed etiology of the compartment syndrome was excessive pressure from elastic wraps, which were placed over gradient elastic stockings. Pressures were 51 mmHg in the superficial posterior, 50 mmHg in the deep posterior, 33 mmHg in the anterior, and 34 mmHg in the peroneal compartments. The patient also developed rhabdomyolysis with myoglobinuria. In addition to supportive care, the patient underwent a dual incision fasciotomy for compartment release. CONCLUSIONS The development of lower extremity compartment syndrome was probably a result of excessive pressure applied by elastic wraps. Elastic wraps should be used with caution in individuals with SCI.

Abstract
Skin closure after a comprehensive posteromediallateral release of clubfeet through a Cincinnati incision may be difficult. This is especially true for cases of severe deformity either primary or recurrent. To deal with this, certain techniques have been developed. These consist of casting the foot in an undercorrected position with subsequent serial cast changes, leaving the incision completely or partially open for closure by secondary intention, using tissue expanders, and using different flap techniques. Five patients with nine clubfoot deformities who were treated with a comprehensive posteromedial-lateral release through a Cincinnati incision and underwent fasciocutaneous flap closure since June 1998 were included in this study. These flaps allowed correction and complete wound closure at the end of surgery without any skin tension. These flaps were constructed either in a rotational or V-Y advancement manner. None of the patients had any major complications. In summary, this new fasciocutaneous flap is a simple and reliable method in cases with primary skin-closure difficulties. It does not require special equipment or a plastic surgeon.

Abstract
This study is a retrospective review of the results of consecutive cases of a transphyseal osteotomy of the distal tibia. Indications for the procedure are significant valgus or varus deformities of the ankle needing acute correction because of problems with the skin and brace fit as well as progressive deformity. Twenty-one patients with a variety of underlying diagnoses, five with bilateral deformities, underwent this procedure. The technique involved making either a medially based closing or opening wedge with the distal limb of the osteotomy through the physis or the physeal scar so that it was very close to the ankle joint. A fibular osteotomy was not necessary except in three ankles. All osteotomies healed. All patients were able to ambulate and use their braces as soon as their osteotomies healed, and none had any further pressure sores or brace-related problems, although some had mild residual valgus or varus deformities. There were no significant leg-length discrepancy problems as a result of the surgery. This osteotomy is a treatment alternative for significant angular deformities of the ankle that require acute correction.

Abstract
STUDY DESIGN A case series in which the halo-Milwaukee brace was used for postoperative immobilization in children with complex congenital and developmental spinal deformities. OBJECTIVES To describe the use of halo-Milwaukee orthosis in a pediatric population for stabilization of the cervical and upper thoracic spine. SUMMARY AND BACKGROUND DATA Postoperative immobilization of the neck and upper thorax can be achieved with cervical orthoses, cervicothoracic lumbar orthosis, halo cast, Minerva jacket, or halo vest. In the young child or in individuals with severe deformities, prefabricated braces often do not provide adequate stability or predictable fit. The halo-Milwaukee brace has proven to be an effective and versatile technique in the management of complex pediatric spinal deformities. METHODS Halo-Milwaukee brace immobilization was used in 12 patients after surgical stabilization of the upper thoracic or cervical spine. Technique and indications are discussed in this report. Surgical outcomes and complications were reviewed retrospectively in all cases. RESULTS Application of the halo-Milwaukee brace was a clinically effective and safe means of controlling the upper thoracic and cervical spine. The orthosis was well tolerated and allowed access to the posterior incision. The brace is easily converted to a standard Milwaukee brace with neck ring. The pelvic segment of the brace is molded before surgery, and in most instances did not require postoperative modification. CONCLUSION The halo-Milwaukee brace is a simple and convenient method of intraoperative and postoperative immobilization. The technique is applicable in patients who cannot be treated with more conventional off-the-shelf orthoses. The brace was well tolerated and allowed for early patient mobilization.

Abstract
Eight pediatric patients who underwent nine simultaneous ipsilateral femoral and tibial lengthenings with the Ilizarov external fixator were reviewed. The patient's demographics, diagnoses, corticotomy levels, mechanical axes, healing indices, amounts of lengthening, and complications were recorded. The patients' average age was 8 years 10 months (5 years 4 months-15 years 10 months) with an average follow-up of 49 months (30-88 months). The percentage of femoral lengthening averaged 16.7% (8-23%) with an average healing index of 28 days/cm (20-38 days/cm). The percentage of tibial lengthening averaged 18% (9.6-23.6%) with an average healing index of 29 days/cm (1940 days/cm). Four complications in three patients occurred as a direct result of the lengthening process. Three of the complications involved soft-tissue contractures, which were each successfully treated with one additional surgical procedure, whereas the fourth complication involved poor bone regeneration and required bone grafting and additional immobilization.

Abstract
OBJECTIVE To determine long-term outcomes and life satisfaction of adults who sustained pediatric spinal cord injury (SCI). DESIGN Structured interview of adults who were 25 years or older who had pediatric SCI. SETTING Community. PARTICIPANTS A convenience sample of 46 patients from a total of 81 patients who received care in an SCI program: 1 refused participation, 4 died, and 30 were lost to follow-up. MAIN OUTCOME MEASURES A structured questionnaire including physical, psychosocial, and medical information. The Craig Handicap Assessment and Reporting Technique and two measures of life satisfaction were also administered. RESULTS Participants were 25 to 34 years old, mean 27 years. Thirty-two had tetraplegia and 14 had paraplegia. Thirty-one were men. Mean years of education was 14. Fifty-four percent were employed, 48% lived independently, and 15% were married. Life satisfaction was associated with education, income, satisfaction with employment, and social/recreation opportunities, and was inversely associated with some medical complications. Life satisfaction was not significantly associated with level of injury, age at injury, or duration of injury. CONCLUSIONS Individuals who had pediatric SCI, much like adult-onset SCI, have the greatest opportunity for a satisfying adult life if rehabilitation emphasizes psychosocial factors such as education, employment, and long-term health management.

Abstract
The occurrence of tetraplegic spinal cord injuries in two patients who had preexisting cervical spine fusions highlights the vulnerable nature of such patients. One patient sustained a C5-6 fracture-dislocation after a motor vehicle accident, despite a spontaneously fused cervical spine as a consequence of his juvenile rheumatoid arthritis. A second patient sustained a C3-4 distraction injury in a sporting injury 2 years after he had undergone a posterior cervical spine fusion because of an aneurysmal bone cyst. Prior to their spinal cord injuries, both patients had no apparent neurologic deficits, were relatively active, and followed no specific precautions for their spines.

Abstract
STUDY DESIGN Case reports. OBJECTIVES Description of neurologic and vascular complications of scoliosis surgery to children and adolescents with ehlers-danios syndrome. SUMMARY OF BACKGROUND DATA There have been no previous reports of neurologic and vascular complications of scoliosis surgery in patients with Ehlers-Danlos syndrome. Scoliosis and vascular fragility are characteristics of certain types of Ehlers-Danlos syndrome. METHODS Case reports and literature review. RESULTS Subsequent to scoliosis surgery, three patients with Ehlers-Danlos syndrome developed neurologic complications: two developed paraplegia, and one developed unilateral foot and ankle weakness with transient neurogenic bladder. Another patient with Ehlers-Danlos syndrome experienced avulsion of segmental arteries during anterior spinal surgery. CONCLUSIONS Patients with Ehlers-Danlos syndrome may be at high risk for neurologic and vascular complications consequent to scoliosis surgery, necessitating careful perioperative evaluation and management.

Abstract
Fifty-five supramalleolar osteotomies were performed in 35 patients for progressive hindfoot valgus in myelomeningocele. All patients were ambulatory. The most common motor level of innervation was L3 in 42 limbs. The average age at surgery was 12 years. The average follow-up was 8 years. Preoperatively, all patients experienced progressive difficulty with brace use, and anteroposterior weight-bearing ankle radiographs showed a valgus tilt of the talotibial angle (TTA) of > or = 10 degrees with an average of 18 degrees. The average postoperative correction of TTA was 17 degrees. The results were graded as follows: excellent, 42 limbs; good, eight limbs; fair, three limbs; and poor, two limbs. The fair and poor limb results were the result of loss of correction or nonunion. The best results were seen when the TTA was corrected to 5 degrees of varus.

Abstract
Arthrograms of 35 hips in 33 children less than 2 years of age with typical development dysplasia of the hip were reviewed. After arthrograms were repeated for 11 hips 6 weeks following the initial test, results were classified into 6 types based on medial pooling ratio and morphology of the acetabular limbus. Using modified Severin's criteria for outcome evaluation, 7 of the 11 hips had been upgraded in type. All hips that were classified as Type I by arthrogram had Severin I results. The relation of arthrographic type and radiographic results was statistically significant. Immediate open reduction is recommended in hips classified as Type VI at first arthrogram or Type III and above at repeat arthrogram.

Abstract
Chondrolysis and avascular necrosis (AVN) are serious complications after slipped capital femoral epiphysis (SCFE). Chondrolysis, or acute cartilage necrosis of the capital femoral epiphysis, can occur in treated and untreated SCFE. Its exact etiology has not been conclusively determined, and there may be some connection with hardware penetration into the joint and its development. Because chondrolysis can occur in both treated and untreated hips, an immune mechanism has been postulated. Although some evidence of immune reaction has been confirmed in the joint, no screening test has yet been developed to determine susceptible individuals. AVN is clearly related to impeded blood supply to the femoral head and to severely slipped unstable acute slips. Forceful reduction of the femoral head must be avoided. However, some slips are so unstable that reductions occur merely with positioning of the patient for operation. Improperly placed fixation devices may also play a role in the development of AVN. Chondrolysis and AVN may not be completely avoidable in the treatment of SCFE.

Abstract
The use of parapodia and reciprocating gait orthoses (RGOs) was reviewed in 41 children and adolescents with spinal cord injuries. Compared with users of RGOs, users of parapodia were younger when injured and when the orthotic was first used, were more likely to be household ambulators and to have higher neurological levels, and were unlikely to continue their use of the parapodium after early school age. Hip contractures that required surgical releases or contributed to discontinuation of orthotic usage were present in six of 26 parapodium users and 12 of 22 RGO users. RGOs and parapodia have a limited but important role in management of pediatric spinal cord injury, and should be used in a developmentally based program responsive to the changing needs of children and adolescents.

Abstract
The ambulatory status of 76 children and adolescents with spinal cord injuries was studied to delineate the natural history of ambulation and to identify factors predictive of successful ambulation. The type of orthotic used and the degree and duration of ambulation depended on age, completeness and level of the neurologic deficit, and lower extremity contractures. Younger age, L3 or better neurologic levels, incomplete lesions with motor preservation, and absence of lower extremity contractures were associated with functional walking. The psychological advantages of ambulation must be weighed against the cost of orthotics and associated training and the nonfunctional nature of ambulation in the vast majority of individuals with spinal cord injuries. In addition, the developmental aspects of pediatric spinal cord injuries require changing therapeutic goals at different developmental stages.

Abstract
The incidence of latex allergy in children and adolescents with spinal cord injuries was investigated using history and laboratory testing. Among 67 individuals with spinal cord injuries, four had histories of latex allergy, and two of these also had positive laboratory tests. There were eight individuals without a history of latex allergy who had positive laboratory tests. Defining latex allergy as a positive history or a positive laboratory test, 12 of the 67 subjects (18%) would be considered allergic to latex. The incidence of latex allergy increased with time since the spinal cord injury. Recommendations are made for the diagnosis, management, and prevention of latex allergy in individuals with spinal cord injuries.

Abstract
The association of Down's syndrome (trisomy 21) with clubfeet has not previously been elaborated. Eight patients with a total of 15 clubfeet were identified for review. Five of these had trisomy 21 noted by chromosomal analysis, and 1 had a mosaic pattern. Two patients did not have chromosomal documentation, but had characteristic features of Down's syndrome. Interestingly, 2 patients had evidence of arthrogryposis as well as Down's syndrome. Four of the 8 patients had other orthopedic anomalies, including scoliosis, atlantoaxial instability, brachydactyly, and coxa valga. All 8 patients had an initial period of casting prior to any surgical intervention. Fourteen of the 15 feet required surgical intervention to afford correction of the deformity. The 6 feet with relatively long-term follow up (average: 5 years) showed that there was 1 excellent, 4 good, and 1 fair result using the criteria of Turco. It appears that, even though Down's syndrome is usually characterized by ligamentous laxity, when clubfeet are associated with this syndrome they are often resistant to nonoperative treatment, and surgical treatment seems to produce an acceptable result.

Abstract
Scoliosis is the most common orthopaedic problem encountered in Rett syndrome. It is characterized by a long C-shaped thoracolumbar curve of neurologic origin. The occurrence of scoliosis in Rett syndrome is age-dependent, with a reported incidence of 36% to 100%. The onset of scoliosis is usually before age 8 years, and rapid curve progression is usually detected early in the second decade. In Rett syndrome, sagittal deformity with excessive kyphosis can progress and necessitates close observation. Orthotic treatment does not alter the natural history of scoliosis or kyphosis. Indications for surgery are curve progression exceeding a 40 degree or 45 degree Cobb angle or curves that cause pain or loss of function. Anterior discectomy, interbody fusion, and posterior fusion with instrumentation can achieve improved correction in young adolescents with significant curves. Surgical intervention should include fusing the scoliotic and the excessively kyphotic segments.

Abstract
For children with myelomeningocele kyphosis, the ideal timing for spinal correction or the correct stabilization technique for preventing the recurrence of deformity are controversial issues. From 1988 to 1992, vertebral kyphectomy and long segment spinal fixation with a special lower-end contouring around the anterior aspect of the sacrum through the sacral foramina (the modified Gillespie's technique) were carried out on six young children with ages ranging from three years and four months to five years and 11 months (average, five years). The indications for surgery were recurrent skin breakdown and/or increasing functional deficits due to curve progression. A mean preoperative kyphosis of 126.3 degrees was reduced to 21.8 degrees postoperatively. There was one case of pseudarthrosis seen at the osteotomy site which was treated with anterior interbody grafting. With a mean follow-up period of 35 months (range, 10-48 months), all patients showed good maintenance of correction and no implant failure. The average loss of correction was 2.7 degrees. We believe that in these young, severely handicapped children, long segment fixation using the modified Gillespie's technique with full or partial segment fusion allows a quick resumption of upright activities, achieves satisfactory correction of kyphosis and minimizes the risk of recurrent deformity.

Abstract
STUDY DESIGN This retrospective study reviewed 100 children with clinically and electrodiagnostically proven Charcot-Marie-Tooth disease (CMTD). OBJECTIVE To determine the incidence of spinal deformity in children with CMTD. SUMMARY OF BACKGROUND DATA A 10% incidence of kyphoscoliosis has been reported. METHODS All charts and electrodiagnostic studies were reviewed to confirm that CMTD diagnostic criteria were met. Existing radiographs on 89 children were available. Cobb angles were measured and deformity was defined as scoliosis > or = 10 degrees and kyphosis > 40 degrees. RESULTS Thirty-seven of 89 CMTD children had spinal deformity. There was scoliosis in 20, kyphoscoliosis in 14, and kyphosis in 3. In children with radiographs taken at maturity, 50% had deformity. The most common scoliotic pattern was a thoracic curve with convexity in either direction. Spinal deformity is more likely in female and Type I patients. CONCLUSIONS This study found an incidence of 37%-50% spinal deformity in children with CMTD, with female and Type I patients at greatest risk. However, the deformity rarely required treatment.

Abstract
Hip dysplasia was recently observed in association with Charcot-Marie-Tooth disease (CMT). We retrospectively reviewed available radiographs of 74 of 100 children with clinically and electrodiagnostically proven CMT and noted six cases of hip dysplasia. Minor hip abnormalities, most commonly increased neck shaft angles, were noted in 21 other patients. Type I usually causes more weakness and had more hip dysplasia than type II. A female predominance was noted but may have resulted from sampling of more immature radiographs in males. Most dysplasia was asymptomatic and was detected only on screening radiographs.

Abstract
A number of predictors that may influence acetabular development after reduction were studied in 75 hips with developmental dysplasia of the hip (DDH). Seventy-nine percent of the hips had satisfactory results of Severin group I or II, and 21% had unsatisfactory results. The best predictor of success in a unilateral case is the center-head distance discrepancy (CHDD) measurement at 1 year follow-up. Ninety-six percent of hips with a CHDD of < or = 6% had satisfactory results, whereas 78% with a CHDD > 6% had unsatisfactory results. This study also confirms that age at reduction and significant improvement in the acetabular index in the first year after reduction are important predictors.

Abstract
Further delineation of a generalized bone dysplasia which we call spondylo-meta-epiphyseal dysplasia, short limb-abnormal calcification type is presented. This dwarfing condition has several serious complications, with the most common cause of death being spinal cord damage secondary to atlantoaxial instability. It is a heritable condition with an autosomal recessive mode of transmission. Radiologic diagnostic criteria are developed on the basis of studies in 8 patients with the oldest being between 4 and 5 years old. The condition is clinically and radiographically apparent neonatally or in early infancy, and it is probable that all or almost all affected individuals will come to medical attention in the age range screened by this study.

Abstract
Toxic shock syndrome (TSS), first described by Todd et al. in 1978, can be a life-threatening entity. Familiarity with the pathogenesis and clinical presentation of TSS may help achieve early diagnosis and prompt appropriate intervention. TSS is not a septicemia, but a toxemia. The most extensively described pathogenesis involves a focus of specific Staphylococcus aureus strains capable of producing an exotoxin (TSST-1). We report two patients who developed TSS while in external fixators and describe their initial symptoms, management, and subsequent problems. This report will serve to alert pediatric orthopaedic surgeons to this entity and enable them to recognize its rather precipitous presentation and initiate appropriate treatment.

Abstract
This study is a retrospective review of nine patients who underwent Luque instrumentation without fusion from 1982-1984. Average age at surgery was 9 years. Average preoperative curve was 51 degrees (30 degrees-70 degrees). All nine patients have had at least one revision. All of the revisions were technically difficult secondary to extensive fibrosis and weakened laminar bone. Spontaneous fusion was documented in all nine patients, limiting further correction. Final follow-up curves averaged 51 degrees (25 degrees-90 degrees). Average gain in spinal height was 5.8 cm (2.3 in) but only a small portion was derived from the instrumented levels. Segmental spinal instrumentation without fusion in immature patients was not effective in control of spinal deformity, nor did it allow anticipated growth under the instrumented regions.

Abstract
Pseudoaneurysm (PA) is recognized as a rare complication after pediatric foot surgery. We identified the incidence, pertinent clinical features, and response to surgical intervention in PA as a complication of foot surgery. Four PAs were identified after 2,756 foot operations, an overall incidence of 0.14%. These patients typically had symptoms between 2 and 3 months after index operation with an enlarging, pulsatile, compressible mass in the plantar medial aspect of the foot. Arteriography was helpful in planning surgical intervention. Operative treatment consisted of ligation and excision of PA in all patients. Final outcome of foot deformity surgery was not compromised.

Abstract
The somatosensory cortical evoked potentials recorded during posterior spine fusion and instrumentation for 99 consecutive patients with idiopathic scoliosis, 18 years of age or younger, were retrospectively reviewed. The potentials were recorded from scalp electrodes while synchronously stimulating both tibial nerves near the ankles. Signal changes observed during consecutive 30-minute time intervals after deformity correction were analyzed. No changes in neurologic status were observed postoperatively. Latency values tended to remain constant on average. A small, but statistically significant, decrease in the first two interpeak amplitudes was observed during the first 30-minute interval after deformity correction. The first interpeak amplitude recovered, while the second remained statistically significantly decreased. No patient had a decrease of greater than 50% in both of the first two amplitudes, which persisted throughout the 60-minute interval immediately after deformity correction. This study demonstrated a tendency for somatosensory cortical evoked potential interpeak amplitudes to decrease during the first 30 minutes after deformity correction. There was a great deal of individual variation, including amplitude increases in many patients. There was no evidence supporting an association between dramatic, sustained amplitude decreases and uncomplicated deformity correction. The value of thoroughly evaluating somatosensory cortical evoked potential signal trends while making intraoperative decisions is emphasized.

Abstract
To determine whether or not the crankshaft phenomenon occurs after spinal fusion in patients with congenital scoliosis, we reviewed 23 curves in 21 patients who were operated on before age 10 years. Operative procedures consisted of various kinds of posterior fusions as well as anterior and posterior hemiepiphyseodeses. Seven of the 23 curves progressed greater than or equal to 10 degrees during the course of follow-up, and six of the seven demonstrated increased rotation and were believed to demonstrate the crankshaft phenomenon. No spines rotated without curve progression. The only statistically predictive factor was length of follow-up. No curve that underwent anterior and posterior hemiepiphyseodeses demonstrated the crankshaft phenomenon. Although the crankshaft phenomenon can occur in young patients operatively treated for congenital scoliosis, apparently it can be prevented by anterior fusion.

Abstract
The intraoperative variability of somatosensory cortical evoked potentials (SCEPs) has been measured for 320 consecutive spinal surgeries and found to be a function of patient diagnosis, neuromuscular status, age, and procedural factors. In many cases, it is likely that this variability severely limits the reliability and usefulness of spinal cord monitoring in detecting early cord compromise. Patients with idiopathic scoliosis, spondylolisthesis, and pseudarthrosis have the smallest spontaneous variability and strongest amplitudes, while those with congenital, paralytic scoliosis, stenosis, or tumor have very variable, weak SCEPs. Patients with neurologic disorders, particularly cerebral palsy, myelomeningocele, Friedreich's ataxia, and peripheral deficits, also have high variability and weak amplitudes. A monitoring quality scoring system is proposed that may be useful during surgery in judging how well the SCEPs can discern surgically related changes in cord function from background variations.

Abstract
Sixteen patients were treated with a new anterior internal fixation device after thoracolumbar or lumbar decompression, and fusion with bone grafting. Ten patients had acute burst fractures, four had metastatic tumors, and two had old, healed fractures with deformity. In the acute fracture group, eight patients had neurologic deficits and seven patients experienced improvement. Six patients had lesions of the conus medullaris, all of which improved. The four patients with metastatic tumors underwent surgery for back and leg pain and all gained significant relief. Two patients had correction of old fracture deformity with satisfactory outcome. Complications were minimal. The new anterior stabilization device provided early stability, allowed early patient mobilization, was easy to insert, and has a low profile. Late collapse, non-union, and kyphotic deformity have not been noted thusfar.

Abstract
An experimental investigation was carried out to create burst fractures and to evaluate the mechanisms and degree of reduction of the intracanal fragment with posterior instrumentation techniques in multisegmental human cadaver specimens. Reduction of the spinal fragment through kyphosis correction and distraction was evaluated using CT imaging. With kyphosis correction alone there was no decrease in canal compromise; in some cases there was a slight increase in canal compromise. Distraction, whether applied before or after kyphosis correction was the effective mechanism in reducing the fracture fragment. Kyphosis correction applied after distraction did not reduce the fragment further. Posterior devices that are used to treat burst fractures of the thoracolumbar spine with intracanal fragments should provide some form of distraction.

Abstract
Outpatient pediatric orthopedic records were reviewed retrospectively in an attempt to identify all patients with congenital spine and urinary tract anomalies. All patients with a positive intravenous pyelogram (IVP) were asked to return for ultrasonographic evaluation. Urinary tract abnormalities were identified in seven (26%) of the 27 patients with documented IVPs. An additional patient was later added to the series, making a total of seven patients who returned for an ultrasonogram, which was then compared with the IVP. Observations and a review of the literature suggest that ultrasonography combined with urinalysis and serum creatinine is the screening protocol of choice in this patient population.

Abstract
We performed a prospective roentgenographic study to determine the incidence of spondylolysis, spondylolisthesis, or both, in 500 unselected first-grade children from 1955 through 1957. The families of the children with spondylolysis were followed in a similar manner. The incidence of spondylolysis at the age of six years was 4.4 per cent and increased to 6 per cent in adulthood. The degree of spondylolisthesis was as much as 28 per cent, and progression of the olisthesis was unusual. The data support the hypothesis that the spondylolytic defect is the result of a defect in the cartilaginous anlage of a vertebra. There is a hereditary pre-disposition to the defect and a strong association with spina bifida occulta. Progression of a slip was unlikely after adolescence and the slip was never symptomatic in the population that we studied.

Abstract
Previous studies have shown an association between an abnormal arterial pattern and bony malformations of the human lower limb. We have dissected and performed arteriography on a congenitally short limb with ectrodactyly in order to examine the relationship between arterial pattern and bony anomalies in another type of deformity. The bony anomalies were a combination of short femur, tibia and fibula, clubfoot with tarsal synostoses, metatarsal absence, ectrodactyly, and a bifid hallux. The arterial pattern was characterized by deficiency of the anterior tibial artery and absence of the plantar arch. Major muscular anomalies were noted in the foot only; the muscles of the missing toe were absent and any muscles that normally cross the midventral line were either missing or failed to cross the midline. The superficial peroneal nerve failed to enter the dorsum of the foot and its sensory distribution was assumed by an extra branch of the sural nerve. The most severe abnormalities of the bones, muscles, arteries, and nerves occurred near the midventral line of the foot. We hypothesize that the abnormal arterial pattern put the limb at risk of teratogenic damage by reducing the number of collateral blood supply routes. We suggest that some event, such as extravasation of blood or embolization, compromised the blood flow in the remaining blood vessels and that this event resulted in both a general shortening of the limb and the specific defects observed in the foot. We interpret the anatomy to be consistent with the vascular teratogenic event occurring near the midline of the foot during the fifth week of embryonic development.

Abstract
We studied 100 consecutive patients with potentially unstable fractures and fracture-dislocations by multiplane computed tomography. The mechanism of failure of the middle osteoligamentous complex of the spine (posterior longitudinal ligament, posterior part of the vertebral body, and posterior annulus fibrosus) was determined by three-dimensional analysis. Three modes of middle-column failure were used to classify the injuries: axial compression (seventy-three patients), axial distraction (fifteen patients), and translation within the transverse plane (twelve patients). Fifty of eighty-six patients who were evaluated in the acute phase of injury underwent operative stabilization, and the mechanism of middle-column disruption determined the type of instrumentation that was used. Compression and distraction injuries of the middle complex could be appropriately treated by Harrington distraction and compression instrumentation, respectively. However, in translational injuries (torn posterior longitudinal ligament) routine Harrington instrumentation was contraindicated due to the risk of overdistraction. Translational injuries were associated with the greatest degree of instability and often had complete ligament discontinuity at the level of the affected vertebrae. Patients with a translational injury had the most severe neural deficits (six of eleven patients studied acutely having a complete spinal cord lesion). Translational injuries of the middle column were treated by segmental spinal instrumentation to provide strong fixation with minimum risk of neural sequelae from passing sublaminar wires. Moreover, postoperative use of a cast over insensate skin was not required. Computed tomography was more sensitive than any other modality in the diagnosis of disruption of the posterior elements in unstable burst fractures, and computer-reconstructed sagittal images were accurate in evaluating the nature of facet-joint failure in distraction injuries. Computed tomography with metrizamide proved superior to either conventional tomography or myelography alone in localizing the site of neural canal compromise in acute thoracolumbar injuries. The mode of failure of the middle osteoligamentous complex as visualized by computed tomography determined the pattern of spinal injury, the severity of the neural deficit, the degree of instability, and the type of instrumentation required.
