The results of bone deformity correction using a spider frame with web-based software for lower extremity long bone deformities.

AIM: To present the functional and radiological results and evaluate the effectiveness of a computer-assisted external fixator (spider frame) in patients with lower extremity shortness and deformity. MATERIALS AND METHODS: The study comprised 17 patients (14 male, 3 female) who were treated for lower extremity long bone deformity and shortness between 2012 and 2015 using a spider frame. The procedure's level of difficulty was determined preoperatively using the Paley Scale. Postoperatively, the results for the patients who underwent tibial operations were evaluated using the Paley criteria modified by ASAMI, and the results for the patients who underwent femoral operations were evaluated according to the Paley scoring system. The evaluations were made by calculating the External Fixator and Distraction indexes. RESULTS: The mean age of the patients was 24.58 years (range, 5-51 years). The spider frame was applied to the femur in 10 patients and to the tibia in seven. The mean follow-up period was 15 months (range, 6-31 months) from the operation day, and the mean amount of lengthening was 3.0 cm (range, 1-6 cm). The mean duration of fixator application was 202.7 days (range, 104-300 days). The mean External Fixator Index was 98 days/cm (range, 42-265 days/cm). The mean Distraction Index was 10.49 days/cm (range, 10-14 days/cm). CONCLUSION: The computer-assisted external fixator system (spider frame) achieves single-stage correction in cases of both deformity and shortness. The system can be applied easily, and because of its high-tech software, it offers the possibility of postoperative treatment of the deformity.

Arthroscopic synovectomy in the treatment of functional ankle instability: outcomes and gait analysis.

BACKGROUND: Natural consequence of repetitive ankle sprains is the chronic ankle instability. Objective of this study was to clarify the gait patterns of functional ankle instability (FAI) patients after arthroscopic synovectomy, but also assessment of postoperative recovery. PATIENTS AND METHODS: Arthroscopic synovectomy was performed to 14 FAI patients with history of unilateral repetitive ankle sprains, pain, and subjective sensation of instability. At a mean 54 months of follow-up (27-84), clinical assessment was conducted with respect to pain, number of ankle sprains, and American Orthopaedics Foot and Ankle Society (AOFAS) scores. Gait analysis was conducted to determine the temporospatial, kinetic and kinematic parameters at the last follow-up. RESULTS: Mean AOFAS scores increased from 68 (range 55-75) to 89 (range 77-100) points (P < 0.01). Mean ankle sprains was 13 in a period of 23 (range 14-48) months (0.58 per month) and decreased to three sprains in a mean time period of 54 months (0.053 per month) (P < 0.01). Mean preoperative and postoperative VAS scores were 8.0 and 2.9, respectively (P < 0.01). During gait analysis, no significant differences were found in ankle joint, including foot progression angles, ankle dorsi-plantar flexion degrees and ground reaction forces (P > 0.01). Among temporospatial parameters, only double support time showed a significant difference (P < 0.01). All patients were satisfied from the procedure and returned to their previous activity level. CONCLUSION: Improved long-term clinical results and scores were obtained in our patient group when compared with the preoperative scores. Also, three-dimensional gait analysis showed that the involved ankles demonstrate similar gait patterns to the uninvolved ankles in patients with FAI.

Does the Ponseti technique affect the vascular development in patients with congenital talipes equinovarus?

In this study, we have evaluated the changes observed in the main arteries of the foot before and after the Ponseti technique. Arterial structures of seven patients were examined using Doppler ultrasound and the parameters studied included the course of the arteries, lumen filling, flow direction, pattern, and velocity. Before the treatment, the side with congenital talipes equinovarus deformity showed decreased blood flow in all arteries, except for the posterior tibial artery. At the second examination, the increase in the flow velocity of both arteries except tibialis anterior arteries was statistically significant. The Ponseti method results in normalization of the arterial structures in extremities with congenital talipes equinovarus.

Intra-articular polyacrylamide hydrogel injections are not innocent.

Osteoarthritis is a chronic disorder characterized by joint cartilage degeneration with concomitant changes in the synovium and subchondral bone metabolism. Many conservative treatment modalities, one of which is intra-articular injections, have been described for the treatment of this disorder. Traditionally, hyaluranic acid and corticosteroids are the agents that have been used for this purpose. Recently, polyacrylamide hydrogels are being used widely. Biocompatibility, nonbioabsorbability, and anti-infectious effect obtained by silver addition made polyacrylamide hydrogels more popular. In this paper, we present a case and the method of our management, in whom host tissue reaction (foreign body granuloma, edema, inflammation, and redness induration) has been observed, as the first and unique adverse effect reported in the literature.

Bilateral simultaneous heterotopic ossification of the reflected head of rectus femoris muscle: a case report and review of the literature.

Lamellar bone formation in an abnormal location is defined as heterotopic ossification. It commonly occurs around the hip joint and most often involves the abductor muscles. It is a benign condition; however, its etiology remains largely unknown. Most previously reported cases have been due to trauma or intramuscular hemorrhage. In this paper, we present a case of bilateral heterotopic ossification of the reflected head of rectus femoris muscle without antecedent trauma or any other known cause, as the first and unique case in the literature. She was treated by excision of the right symptomatic bony mass via a modified Smith-Petersen approach. Postoperatively, she received 75 mg indomethacin daily for six weeks. She was pain-free and obtained full range of motion 3 weeks after the first intervention.

Comparison of two different measurement methods to determine glenoid bone defects: area or width?

BACKGROUND: This study compared two different techniques that have been used to measure the glenoids of patients with recurrent anterior shoulder dislocation. METHODS: We analyzed 36 patients who had received arthroscopic Bankart repair for anterior shoulder instability. Retrospectively, 3-dimensional computed tomography images of both shoulders were available for these patients. Two measurement methods were compared to determine the glenoid defects. One of these techniques is based on linear measurement, previously defined as the glenoid index. The other method is based on surface area measurement. Subsequently, 3 more diameters and the average values obtained from these diameters were compared with the surface measurement method. Pearson correlation coefficient (r) was assessed to determine the relationship. RESULTS: There was an almost perfect relationship between measurement methods when the defect area was less than 6% of the inferior glenoid circle (r, 0.915; P < .001). This relation decreased and the difference became more pronounced (r, 0.343; P = .657) when the bone loss exceeded 14% of the inferior glenoid circle. The highest correlations with the actual defects were the average values obtained from 4 different diameters (r, 0.964; P < .001) and the 4-o'clock position of the single diameter measurements (r, 0.860; P = .001). In addition, 11 patients had crescent-like defects, demonstrating a relatively low correlation between the measurement methods (r, 0.679; P = .021). CONCLUSION: Although the best correlation was achieved from average values obtained from different diameter positions, in practical use, we advise a linear measurement to estimate the glenoid bone loss at the 4-o'clock position to achieve a high correlation between the measurement techniques.

The role of simple elbow dislocations in cubitus valgus development in children.

PURPOSE: We investigated the functional and radiological outcomes of conservatively treated simple traumatic elbow dislocations and subsequent incidence of cubitus valgus development in children. METHODS: Eleven patients (one female, ten male; mean age 9.8 years, range seven to 12 years) who presented to our hospital with simple elbow dislocations and were conservatively treated between July 2008 and September 2010 were included in the study. All were posterolateral closed dislocations. None of the patients had accompanying elbow fractures. All patients had pre- and postoperative radiographic examinations. The carrying angle of the involved elbow was measured and compared to the contralateral non-injured elbow during follow-up. The incidence and severity of cubitus valgus development was assessed. The functional and clinical outcomes were evaluated using the Mayo Elbow Performance Scale. The mean monitoring period was 24.3 months (range 19-30 months). RESULTS: All patients had satisfactory good and excellent results (85-100 points; mean 96.8 points) according to the Mayo Elbow Performance Scale. The final average elbow flexion was 137° (range, 130-145°) and average extension was 8.6° (range 0-20°) with full supination and pronation in traumatic elbow. Four patients (36.4%) had an average increase (cubitus valgus) of 14.5° (10-20°) in carrying angle compared to the other elbow. CONCLUSIONS: While isolated traumatic dislocation of the elbow is uncommon among children, it can be successfully treated by urgent closed reduction, proper fixation of the elbow and appropriate timely rehabilitation. However, it should be considered that some patients may develop cubitus valgus deformity in a later period. Therefore, each patient with a simple traumatic elbow dislocation should be followed, and the parents should be informed of the potential for any deformity development.

Synergistic Effect of TGF-ß1 And BMP-7 on Chondrogenesis and Extracellular Matrix Synthesis: An In Vitro Study.

INTRODUCTION: The purpose of the present study seeks to determine the signal timing of BMP-7 and TGF-ß1 from a novel chitosan based hydrogel system that may affect chondrocyte proliferation resulting in the presence of a synergism seen conspicuously in consecutive controlled delivery. METHODS: Four groups of cultured chondrocytes were seeded on a novel designed chitosan based hydrogel. The hydrogel was left empty (control) in one group and loaded with BMP-7, TGF-ß1 and their combination in the other groups, respectively. Hydrogel structure was analyzed with scanning electron microscope. The release kinetics of Growth Factors (GFs) was determined with ELISA. Chondrocyte viability and toxicity after being tested with MTS and collagen type II synthesis, were quantified with western blotting. Canonical regression analysis was used for measuring statistical evaluation. RESULTS: Chitosan based hydrogel allowed controlled release of GFs in different time intervals for BMP-7 and TGF-ß1. Double peak concentration gradient was found to be present in the group loaded with both GFs. In this group, substantially higher chondrocyte growth and collagen synthesis were also detected. CONCLUSIONS: We concluded that, chitosan based hydrogel systems may be adjusted to release GFs consecutively during biodegradation at the layers of surface, which may increase the cell number and enhance collagen type II synthesis.

The role of debridement and reconstruction of sagittal balance in tuberculous spondylitis.

BACKGROUND: An accepted comprehensive clinical approach to the deformed spine with tuberculous infection is still lacking. We aimed to determine the usage of a staged algorithm in the treatment of kyphotic spine with tuberculous infection and to present the clinical results of the patients treated with the help of this protocol. MATERIALS AND METHODS: 54 patients (28 females, 26 males) with a mean age of 39.2 (22-76) years. Preoperative, early postoperative, and followup clinical and radiologic results were evaluated retrospectively. The patients were classified into Kaplan A (kyphotic deformity <30°), Kaplan B (kyphotic deformity 30°-60°) and Kaplan C (kyphotic deformity >60°). They were operated by posterior instrument with anterior debridment (Kaplan A), debridment with anterior bone grafting (Kaplan B) and anterior column resection and bone grafting in Kaplan C. RESULTS: Tuberculous involvement were seen at more than one level in 40 patients and paraspinal abscess were detected in 31. Preoperative focal kyphotic deformity was reconstructed with an average of 19 (9-38) degrees. Twenty-six patients had neurologic compromise with different severities and 12 of them improved after the surgical intervention. Improvement in work ability and pain status was detected in 52% and 61% of the patients, respectively. Wound complications responding to medical care were detected in nine patients. Initial kyphotic deformity was found as an important parameter in selecting the surgical procedure. CONCLUSION: Regarding resected amount of infected osseous material, as planned preoperatively, have resulted with better concordance between anterior and posterior column heights and better sagittal alignment. We could correct kyphosis and improve sagittal balance with staged algorithm as used by us.

Relationship between the size of bone marrow edema of the talus and ankle pain.

BACKGROUND: We sought to determine the changes in the size of the edema observed on MRI scans and its relation to the patient's pain during activity and pain during rest in bone marrow edema. METHODS: A total of 26 patients were followed up at 3-month intervals for a period of 1 year. During the follow-ups, magnetic resonance imaging scans of the patients' ankles were obtained; the scores obtained on the American Orthopaedic Foot and Ankle Society functional rating scale and visual analog scale were determined. The changes in these parameters and the correlation between them were examined. RESULTS: The size of the edema as observed on magnetic resonance imaging scans decreased, and the pain during activity and rest decreased. Although there is a correlation between the decrease in the edema size observed on magnetic resonance imaging scans and decrease in the pain during activity, there is no correlation between the decrease in the edema size observed on magnetic resonance imaging scans and the decrease in pain during rest. CONCLUSIONS: Patients can be informed more precisely, that the pain during rest and activity may not decrease after the third and sixth month, respectively. Magnetic resonance imaging may not alter after the ninth month, so it may not be necessary to be performed again.

Giant cell tumor of second and third metatarsals and a simplified surgical technique: report of two cases.

Giant cell tumor (GCT) is a rare benign tumor that often arises in tendon sheath as well as long bones of the lower extremity in adults, although localization in the metatarsus is rare. In this report, the authors describe the rare case of GCT localized to the third metatarsal GCT in a skeletally mature 17-year-old girl, and also describe the results of distal metatarsal resection with Kirschner wire stabilization for the treatment of this condition.

The efficacy of magnetic resonance imaging and x-ray in the evaluation of response to radiosynovectomy in patients with hemophilic arthropathy.

OBJECTIVE: We aimed to assess the role of Magnetic Resonance Imaging (MRI) and X-Ray in the evaluation of response to radiosynovectomy (RS) in patients with hemophilic arthropathy. MATERIAL AND METHODS: Eleven patients who suffered from hemophilic arthropathy with a mean age of 11.7 (range between 7-15) were included in this study. 148-185 MBq Yttrium 90 silicate (Y-90) was administered intraarticularly to ten knee joints and one patient was treated with intraarticular 74 MBq Rhenium 186 (Re-186) injection into his ankle. Before radiosynovectomy, plain anteroposterior and lateral X-rays of the target joints were obtained by standard technique. The follow-up MRI and X-ray studies of the patients were done 6 months after RS. Pettersson hemophilic arthropathy scales were utilized to stage the condition of the joints on plain X-ray and classification of the investigated joints on MRI were done according to Denver score. The clinical assessment of the efficacy of the RS was made with the comparison of the average bleedings before and after the intervention. RESULTS: During the 6-month follow-up period after RS, an improvement in number of hemarthrosis 75% or greater compared with the prior six months occurred in six joints (54.5%). The Pettersson scores worsened in 1/11 (9%), remained unchanged in 9/11 (81.8%), and improved in 1/11 (9%) joints. At the 6-month follow-up, the MRI score worsened in one (9%) and was unchanged in 10/11 joints (90.9%). CONCLUSION: MRI is a more sensitive tool than plain radiography for evaluating and follow-up of joint disease in persons with hemophilia, but both methods don't show correlation with the therapeutic response Conflict of interest:None declared.

Is there any correlation between the preoperative parameters and correction loss in patients operated for hyperkyphosis?

OBJECTIVES: Preoperative, postoperative, and latest follow-up data of sagittal balance and spinopelvic parameters of our patients treated surgically for hyperkyphosis were evaluated retrospectively, to determine whether there is any correlation between the preoperative pelvic incidence and postoperative correction loss. METHODS: Totally 33 patients (18 females) who were operated for hyperkyphosis and, were reached at the latest follow-up were included in the study. Age at operation, gender, date of operation, etiology and level of the deformities, instrumentation, and graft types were noted in detail. The kyphosis angles were measured by the Cobb method. The preoperative and postoperative spinopelvic parameters (pelvic incidence, sacral slope, and pelvic tilt) were recorded. RESULTS: The average follow-up was 4 years (range 3-8 years). The mean age at operation was 21 years (range 14-40 years). Scheuermann kyphosis was diagnosed as the etiological factor in 18 patients (53%). The mean preoperative kyphosis angle was 76° (range 55-98°), which decreased postoperatively to 38° (range 20-55°) (p<0.05). The mean kyphosis angle two years postoperatively was 41° (p>0.05). Preoperative and latest follow-up spinopelvic parameters were also not significantly different. Furthermore, no correlation could be found between the age at operation, instrumentation level, spinopelvic parameters, and correction loss. CONCLUSION: There is no correlation between the preoperative pelvic incidence and postoperative correction loss in patients treated surgically for hyperkyphosis. Further studies with larger sample size and longer follow-up should be conducted.

[Crescentic distal metatarsal osteotomy for the treatment of hallux valgus: a prospective, randomized, controlled study of two different fixation methods]. / Halluks valgus tedavisinde kresentik distal metatarsal osteotomi: Iki farkli tespit yöntemiyle ileriye dönük, randomize, kontrollü bir çalisma.

OBJECTIVES: This study was designed to draw attention to a distal metatarsal osteotomy technique, which has been somewhat overlooked for the treatment of hallux valgus, and to compare the clinical and radiographic results of two different fixation methods. METHODS: The study included 16 feet of 13 patients (11 women, 2 men) who were treated with crescentic distal metatarsal osteotomy for mild-to-moderate hallux valgus (<35 degrees ). The patients were randomized to two fixation methods with two cross K-wires (group 1; 7 patients, 8 feet) and a compressive screw (group 2; 6 patients, 8 feet). The results were evaluated using the AOFAS (American Orthopaedic Foot and Ankle Society) clinical rating scale for hallux, and a visual analog scale for pain. Radiographic measurements included the hallux valgus angle (HVA), first/second intermetatarsal angle (IMA), and distal metatarsal articular angle (DMAA), before and 12 months after surgery. RESULTS: There were no significant differences between the two groups with regard to pre- and postoperative AOFAS scores and pain scores, which showed significant improvements in both groups at the end of one-year follow-up (p<0.001). The HVA and IMA significantly decreased from 32 degrees to 19 degrees and from 12 degrees to 6 degrees in group 1, and from 30 degrees to 17 degrees and from 12 degrees to 8 degrees in group 2, respectively (p<0.001). A similar improvement was also seen in the DMAA (p<0.001). Postoperative radiographic improvements were similar in both groups. One patient in group 1 underwent revision surgery with the same technique due to recurrence, and one patient in group 2 had delayed union. CONCLUSION: Crescentic distal metatarsal osteotomy may be an appropriate technique in the treatment of mild-to-moderate hallux valgus.

[Long-term results of conservative treatment for thoracolumbar compression fractures]. / Torakolomber omurga kompresyon kiriklarinda konservatif tedavinin uzun dönem sonuçlari.

OBJECTIVES: We evaluated the radiologic and clinical outcomes of conservative treatment for thoracolumbar compression fractures. METHODS: Forty-three patients (28 males, 15 females; mean age 39 years; range 24 to 54 years) were treated conservatively for 47 thoracolumbar compression fractures. All the patients were assessed by plain radiograms and computed tomography. According to the Denis classification, there were eight type A, 20 type B, 12 type C, and seven type D fractures. Involvement was at L1 in 30, L2 in five, and T12 in 12 fractures. There were no neurological deficits. Treatment involved use of a body cast for two months, followed by a thoracolumbosacral orthosis for four months. Radiographically, local kyphosis angle and sagittal index were measured before treatment, after casting, and at the final follow-ups. Pain and functional scales proposed by Denis et al. were also utilized. The mean follow-up was 7.5 years (range 6 to 11 years). RESULTS: The mean local kyphosis angle and sagittal index were measured as 12.6 and 13.7 degrees before treatment, and 5.9 and 7.0 degrees after casting, respectively (p<0.05). However, both did not differ significantly from the baseline at the final measurements (12.7 and 13.9, respectively; p>0.05). The mean pain and functional scores were 1.4 and 1.6, respectively. Four patients had moderate to severe back pain despite mean kyphosis angles of 12 (baseline), 13.5 (after casting), and 14.8 (final). Two patients required substitution of the body cast for orthosis due to excessive sweating, and three patients received local treatment for skin problems secondary to the use of orthosis. CONCLUSION: If the kyphosis angle is less than 30 degrees, compression fractures are supposed to be stable to be treated conservatively with satisfactory clinical results. Functional results seem to be unaffected from the fact that casting does not improve radiographic parameters in the long-term.

Distal first metatarsal dome (crescentic) osteotomy for repair of mild to moderate hallux valgus deformity.

Hallux valgus is one of the most common foot deformities. Despite the large number of techniques described for hallux valgus correction, there has been much controversy regarding the best procedure to use. Distal osteotomies have long been done for mild to moderate deformities. Although presented previously, based on a review of the literature, this technique does not appear to be regularly used by many surgeons. This article presents a distal metatarsal osteotomy as easy to perform and useful for the repair of mild to moderate hallux valgus deformity, wherein the first metatarsal angle measures less than 14 degrees.

How are outcomes affected by combining the Pemberton and Salter osteotomies?

UNLABELLED: The Pembersal operation combines features of the Pemberton and Salter osteotomies. Results have usually been reported in patients with dysplasia but without frank dislocation. We asked if the following factors influence the outcome of the Pembersal operation in patients with dislocated hips: triradiate cartilage damage causing early closure; the acetabular index improvement; and the age of the patient at time of operation. We assessed triradiate cartilage damage, a modified McKay clinical classification, acetabular index, center-edge angles, Reimers index, acetabular depth-to-width ratios, Severin classification and Tönnis grading of 33 patients (44 hips) have been evaluated in this retrospective study. The mean age at surgery was 5 years (range, 1.5-14 years). The minimum followup was 5 years (mean, 10.5 years; range, 5-17 years). Preoperatively, three (7%) hips were Tönnis Grade 2, 10 (23%) were Grade 3, and 31 (70%) were Grade 4. Eight (18%) hips were Severin Class 1, 32 (73%) Class 2, and four (9%) were Class 3. According to McKay's criteria satisfactory results with a rate of 76% were obtained. Premature closure of the triradiate cartilage occurred in eight (18%) hips and postoperative avascular necrosis of the femoral head in three (6%) hips. Satisfactory clinical and radiographic improvements in the aforementioned parameters can be obtained by Pembersal osteotomy. LEVEL OF EVIDENCE: Level IV, therapeutic case series. See the Guidelines for Authors for a complete description of levels of evidence.

Thorax deformity, joint hypermobility, and anxiety disorders.

OBJECTIVE: To evaluate the association between thorax deformities, panic disorder, and joint hypermobility METHODS: The study includes 52 males diagnosed with thorax deformity, and 40 healthy male controls without thorax deformity, in Tatvan Bitlis and Isparta, Turkey. The study was carried out from 2004 to 2006. The teleradiographic and thoracic lateral images of the subjects were evaluated to obtain the Beighton scores; subjects' psychiatric conditions were evaluated using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-1), and the Hamilton Anxiety Scale (HAM-A) was applied in order to determine the anxiety levels. Both the subjects and controls were compared in sociodemographic, anxiety levels, and joint mobility levels. In addition, males with joint hypermobility and thorax deformity were compared to the group with thorax deformity without joint hypermobility. RESULTS: A significant difference in HAM-A scores was found between the groups with thorax deformity and without. In addition, 21 subjects with thorax deformity met the joint hypermobility criteria in the group with thorax deformity, and 7 subjects without thorax deformity met the joint hypermobility criteria in the group without thorax deformity, according to Beighton scoring. The Beighton scores of the subjects with thorax deformity were significantly different from those of the group without deformity. Additionally, anxiety scores of the males with thorax deformity and joint hypermobility were found higher than males with thorax deformity without joint hypermobility. CONCLUSION: Anxiety disorders, particularly panic disorder, have a significantly higher distribution in male subjects with thorax deformity compared to the healthy control group. In addition, the anxiety level of males with thorax deformity and joint hypermobility is higher than males with thorax deformity without joint hypermobility.

[Arthroscopic rotator cuff repair: evaluation of outcomes and analysis of prognostic factors]. / Artroskopik rotator manset onarimi: Sonuçlar ve belirleyici faktörlerin analizi.

OBJECTIVES: The purpose of this study was to evaluate the results of arthroscopic rotator cuff repair of full-thickness tears and to determine prognostic factors. METHODS: Forty-one shoulders of 40 patients (16 males, 24 females; mean age 56 years; range 39 to 72 years) unresponsive to conservative treatment were evaluated. The mean symptom duration was 15 months (range 2 to 24 months). Involvement was on the right in 34 shoulders, on the left in seven shoulders, 80% being on the dominant side. The range of motion was measured with a goniometer, muscle strength was measured manually. Clinical and functional evaluations were based on physical and radiological examinations, and the UCLA scale. The mean follow-up was 37 months (range 12 to 61 months). Prognostic factors included age, symptom duration, range of motion, muscle strength, tear size, retraction and quality of tendon, and fatty degenerative changes. RESULTS: According to the UCLA scale, the results were satisfactory in 29 shoulders (70.7%), moderate in five (12.2%), and poor in seven (17.1%). Six shoulders (14.6%) required revision surgery. Postoperative improvements in forward flexion and muscle strength were significant (p<0.05), whereas change in external rotation was insignificant (p>0.05). Age, tear size, retraction and quality of tendon, and fatty degenerative changes were found to significantly affect unsatisfactory results (p<0.05). Preoperative symptom duration, range of motion, and muscle strength were not effective on the results (p>0.05). CONCLUSION: Our results are not as successful as those obtained from open procedures. The results may be more satisfactory through improving arthroscopic skills and taking prognostic factors into consideration in patient selection.

Combined fibular and tarsal agenesis in a case of lower extremity hemimelia.

Fibular hemimelia is a congenital disorder characterized by partial or total absence of the fibula. The appearance of the affected limb can range from barely detectable to severe deformity. An affected extremity typically displays a valgus foot and ankle, shortening of the leg, anterior bowing of the tibia and knee, tarsal coalition, as well as radiographic absence of 1 to several lateral rays (1, 2). We encountered an adult patient who displayed fibular agenesis in combination with absence of the ipsilateral talus and cuboid. Because of the rarity of this deformity, we believed that it was important to describe her case despite the fact that, after evaluation and discussion of treatment options, the decision was made to continue to accommodate the deformity with an orthosis.
