Varus tibial joint line obliquity: a potential cause of femoral component malrotation.

In 60 consecutive total knee arthroplasties done in 52 patients with primary osteoarthritis and varus or neutral tibiofemoral alignment, the posterior condylar angle was calculated intraoperatively and averaged 3.98 degrees (range, 0 degrees-9 degrees). Eighteen knees had a posterior condylar angle value less than 3 degrees whereas 27 knees had a posterior condylar angle value of 5 degrees or greater. Final rotational alignment of the femoral component was set parallel to the transepicondylar axis. Only one of these 60 knees required a lateral retinacular release for proper patellar tracking during the knee arthroplasty. When compared with three previously defined angles measured on the radiographs taken preoperatively, only the tibial plateau-tibial shaft angle values were correlated significantly with the value of the posterior condylar angle. As the tibial varus joint line obliquity increased, there was a distinct tendency for the transepicondylar axis to be rotated more externally relative to the posterior condylar axis. This variance suggests that the use of the posterior condylar axis as a rotational reference is inappropriate in many knees with arthritis with varus or neutral tibiofemoral alignment. In particular, varus tibial joint line obliquity of more than 4 degrees increases the likelihood of femoral component malrotation when the posterior femoral condyles are used to reference femoral component rotation.

Posterior instability of the shoulder after supracondylar fractures recovered with cubitus varus deformity.

Cubitus varus is a common complication after supracondylar fractures of the humerus, and there have been several discussions about the timing of correction of deformity. Although surgery is performed mainly for cosmetic purposes, the authors in this article show the relationship between cubitus varus and dislocation of the ulnar nerve and posterior instability of the ipsilateral shoulder with a Bankart lesion in three children. A special type of osteotomy to obtain three-dimensional correction was made. All shoulders were found to be clinically stable at follow-up with full pain-free range of motion. Corrective osteotomy of the distal humerus itself corrected the varus angulation and dislocation of the medial portion of the triceps in two patients and prevented the ulnar nerve from dislocating. The authors' experience illustrates the importance of biomechanics in understanding the pathoanatomy of cubitus varus; this deformity should not be regarded as a cosmetic deformity and should be treated early.

Dynamic pedobarograph in evaluation of varus and valgus foot deformities.

Objective documentation of dynamic varus and valgus deformities of the hindfoot is still a clinical dilemma. In a review of spastic foot deformities, clinical, radiographic, and foot pressure data were collected in 108 children with cerebral palsy. According to the clinical assessment, five categories of foot deformities were defined: severe varus, varus, neutral, valgus, and severe valgus. A coronal index of the pedobarograph was determined by comparing the pressure/time integral under the medial column to that under the lateral column of the foot. Coronal index is highly correlated with clinical assessment and offers better information than radiographic measurements in differentiating the clinical categories. The authors recommend the pedobarograph as the primary evaluation tool to measure the severity of deformity for patients with varus and valgus foot dysfunction. The severity of the deformity can be monitored with a single measurement, which has the best correlation with the clinical assessment. The clinical assessment is still the primary tool to determine general patterns, but it is difficult to apply an objective measurement. Radiographic study is most useful for the preoperative assessment when surgery is indicated.

[Treatment of cubitus varus deformity in adults with lateral closing wedge osteotomy].

OBJECTIVE: To explore the proper methodology to treat cubitus varus deformity in adults with lateral closing wedge osteotomy. METHODS: The clinical data of 20 adult patients with post-traumatic cubitus varus deformity who underwent lateral closing wedge osteotomy and were followed up for 40 months on average were analyzed. RESULTS: twenty-seven of the 28 patients showed excellent heal, and one case of delay in healing occurred. Eighteen elbow joints were in a neutral position, 6 were slightly varus, and 4 were varus. Tardy ulnar nerve palsy occurred in 5 cases. Reduction of elbow flexion was 11 degrees, even more than 20 degrees in 5 cases. Four patients were able to flex their elbows by 120 degrees or less. The reduction of extension was 3.4 degrees on average. Two patients showed failure of internal fixation, Kirshner wires were used in both of which. CONCLUSION: Exact pre-operative planning of osteotomy, minimal injury to the soft tissues, proper dealing of the ulnar nerve, and stable internal fixation are the key factors that improve the function of elbow joint after the lateral closing wedge osteotomy and reduce the post-operative complications.

Congenital hallux varus: case presentation and review of the literature.

Congenital hallux varus is uncommon as an isolated deformity. Many authors cite this deformity in conjunction with metatarsus varus or talipes equino varus deformities. An unusual case of bilateral congenital hallux varus is presented in a 9-month-old. A review of etiologies and treatment methods are given.

Combined split anterior tibial-tendon transfer and intramuscular lengthening of the posterior tibial tendon. Results in patients who have a varus deformity of the foot due to spastic cerebral palsy.

Twenty patients who had a varus deformity of the foot secondary to spastic cerebral palsy had twenty-two operations involving combined split anterior tibial-tendon transfer and intramuscular lengthening of the posterior tibial tendon, with and without concomitant lengthening of the Achilles tendon. Preoperatively, all patients had had a dynamic varus deformity of the hindfoot and adduction of the forefoot in both the stance phase and the swing phase of gait. At an average follow-up of 6.2 years (range, 2.3 to 8.8 years), there were fourteen excellent, four good, and four poor clinical results. Two patients who had a fixed varus deformity of the hindfoot and one patient who had a very weak anterior tibial muscle had a poor result. We concluded that the combined procedure is effective for correction of a flexible varus deformity of the foot in patients who have spastic cerebral palsy.

Histomorphometry and vitamin D metabolism of valgus-varus deformity in broiler chickens.

Vitamin D metabolite levels and tibiotarsal histomorphometric characteristics were determined in 49-day-old male broilers. Valgus-varus bone deformity was present in 5.2% and tibial dyschondroplasia (TD) in 3% of these broilers, which were raised on floor litter under seemingly normal nutritional, space, and lighting conditions. No significant weight differences were observed between normal and lame broilers. The plasma levels of 25-OH-D were the same in lame and normal broilers. However, 1,25-(OH)2D plasma levels were reduced 28% in broilers with valgus-varus deformities but normal in broilers with TD. Anatomically, there were three different patterns of bone development in the undecalcified mid-diaphyseal sections. The pattern with the least periosteal growth, lowest tetracycline labeling, and smallest marrow cavity was most often seen in valgus-varus deformities. Patterns with greatest periosteal growth, high tetracycline labeling, and larger marrow cavities were more representative of normal broilers. It was hypothesized that defective prostaglandin metabolism reduced 1,25-(OH)2D levels, contributing to the overall reduction in bone formation and bone resorption observed in broilers with valgus-varus bone deformity.

Dwyer osteotomy for treatment of calcaneal varus.

Treatment of varus deformity of the rearfoot is satisfactorily corrected with a lateral closing wedge osteotomy of the calcaneus. Whether the condition being treated is club foot, pes cavus deformity, or calcaneal varus alone, statistics show the varus component is consistently resolved with this osteotomy approach. A case report of calcaneal varus is presented, including a postoperative complication with resolution.

[Dwyer's calcaneal osteotomy for varus deformity of the foot. (A follow-up study including gait analysis) (author's transl)].

A follow-up study on 20 patients one to 9 years after lateral wedge resection of the calcaneus according to Dwyer is reported. In 18 feet with neurogenic varus deformity of the hind foot, the angle between the axis of the lower leg and the heel was altered from 11.4 degrees +/- 1.4 degrees SD varus to a normal value of 5.9 degrees +/- 0.9 degrees SD valgus. The position of the calcaneal tuberosity was changed from 6.7 degrees +/- 1.1 degree SD varus to 0.1 degree +/- SD varus in 7 congenital club feet. The osteotomy reduced accompanying deformities of pes cavus and pes adductus in the operated children.

Surgical treatment of metatarsus varus during the growth period.

The writers describe their experience in the treatment of congenital metatarsus varus. They describe an original technique for anterior transfer or shortening of peroneus brevis which they consider to be indicated when the varus deformity is less than 15 degrees and is correctable manually. They also describe Heyman's technique and give their results in twenty-five cases. They consider that this operation is indicated only for varus deformity of the forefoot exceeding 15 degrees which is correctable manually. In both these techniques it is essential that the hindfoot should be in the correct midline axis. Where manual correction of the hindfoot is not possible they advise Dillwyn Evans' operation. In varus deformity of the 1st metatarsal exceeding 15 degrees, and not correctable manually, they suggest osteotomy of the base of this bone, displacing it the correct degree and fixing it with a wedge of homoplastic bone inserted into the gap.

Rotational deformity of the distal humerus in cubitus varus.

The medial rotation deformity of the distal humerus usually exists in the cubitus varus deformity but has received little attention. Study of this deformity in 29 cases of cubitus varus was carried out using the osteotomized bony specimens that were removed during closed wedge osteotomy in order to determine the actual bone deformity. The average duration of the varus deformity was 5.6 yrs (range 1 to 11). The medial rotation deformity of the distal humerus averaged 27 degrees (range 15 to 45). There was no correlation between the degree of rotation and that of the varus deformity (correlation coefficient r = 0.15). The affected-side shoulder compensated well in both internal and external rotation, and had a greater arc of rotation than that of the normal side. The affected-side shoulder exhibited an internal rotation deformity with an average of 16 degrees (range 5 to 25), with restriction of external rotation of only 13 degrees (range 0 to 20) in comparison to normal side shoulder.

[Open osteotomy of the first cuneiform in the treatment of tarsometatarsal varus in children].

MATERIAL AND METHODS: Open wedge osteotomy of the first cuneiform was used for correction of metatarsus varus primus. The osteotomy interested the medial, dorsal and plantar face of the first cuneiform, but lateral cortex should be carefully left intact, it is used like a hinge for opening the osteotomy. This procedure is carried out when varus of the tarsometatarsal joint is superior to 20 degree, it is reduced to its normal value, between 5 and 10 degree. Osteotomy is stabilized with bone graft. In resistant metatarsus adductus, closed wedge osteotomy of the cuboid has been added to correct the varus deformity of the fore foot, it allowed lateral swing of the forefoot: the bone excised from cuboid is used to stabilized medial osteotomy. Twelve children, aged 5 to 15 years, underwent medial open wedge osteotomy of the first cuneiform for correction of 16 feet including 8 hallux valgus, 6 serpentine feet, defined as adductus of the forefoot and valgus of the hindfoot, and 2 clubfeet. In all hallux valgus it was associated with release of all contracted lateral structures and in three cases, shortening of the proximal phalanx. In serpentine feet and clubfeet closed wedge osteotomy of cuboid has been added. RESULTS: Results have been studied with follow up ranging between 18 months and 5 years. In 8 cases of hallux valgus, one case showed recurrence; failure was related to technical deficiency, because the lateral cortex of the first cuneiform was cut accidently leading to over lengthening of the first column. In 6 resistant metatarsus varus and 2 clubfeet, we didn't find any recurrence at term of our follow up. DISCUSSION: In all cases, growth of metatarsals hasn't been disturbed at term of our follow up and tarsometatarsal joint remained well corrected, because proximal epiphyseal plate of metatarsal was normally positioned and saved from damage.

[Treatment of hallux valgus by varus osteotomy of the first phalanx associated with adductor plasty].

PURPOSE OF THE STUDY: Sixty two hallux valgus treated by first phalanx varus osteotomy associated to adductor hallux plasty were reviewed with a minimum follow-up of 4 years. MATERIAL AND METHODS: 48 females and 2 males were operated. Average age was 46 years. The forefoot was grecian 40 times. The pre-operative metatarsus varus was at an average of 14.2 degrees when the metatarso-phalangeal valgus was 33.3 degrees. The interphalangeal valgus was 8.25 degrees. The first phalanx base lateral translation measured an average of 5.8 mm. Sesamoids were always dislocated. 36 patients were treated in the same operative time, using this associated approach at different level. RESULTS: Results were evaluated according to 3 Groulier's criteria. In 10 cases, a post-operative pain persisted. Shoe wearing continually improved. The great toe valgus was corrected in 31 cases (50 per cent). The correction was partial in 20 cases (32.3 per cent) but on radiographs, only 34 cases (54.8 per cent) conserved a normal joint space. The first phalanx base lateral translation only improved partially. It measured an average of 408 mm. The global result was good in and very good, 67 per cent, while patients subjective estimation was good or very good in 90.3 per cent. DISCUSSION: The study of this series of first phalanx varus osteotomy associated to adductor plasty shows lateral subluxation partial correction, factor of long term modification on articular metatarso-phalangeal joint space. The adductor plasty associated to abductor disinsertion showed a results improvement compared with other published series. CONCLUSION: The first phalanx varus osteotomy associated to adductor plasty should be limited to moderate hallux valgus deformity with interphalangeal valgus and without any major articular incongruity.

Wear patterns on tibial plateaus from varus and valgus osteoarthritic knees.

The size and location of articular cartilage wear was assessed on 106 varus and 37 valgus osteoarthritic tibial plateaus resected during total knee arthroplasty. Anterior cruciate ligament integrity was assessed intraoperatively, and calibrated digital images were used to measure the wear patterns. Complete anterior cruciate ligament deficiency was seen in 25% of the varus and 24% of the valgus knees. Wear patterns on anterior cruciate ligament intact and attenuated varus tibial plateaus occurred in the middle to anterior aspect of the medial plateau. Anterior cruciate ligament deficient varus plateaus had significantly larger wear areas located more posterior on the medial plateau. In contrast, anterior cruciate ligament intact and deficient valgus tibial plateaus had wear located posterior to the center of the lateral plateau. Anterior cruciate ligament integrity is a discrete feature of advanced osteoarthritis that strongly influences the articular wear patterns. The anterior cruciate ligament deficient wear patterns show a wear mechanism that is consistent with the posterior femoral subluxation and posterior tibiofemoral contact observed after acute anterior cruciate ligament rupture. These observations provide insight into the altered knee mechanics that exist in osteoarthritic knees and the resulting mechanical factors that contribute to degenerative changes.

The effect of unilateral varus rotational osteotomy with or without pelvic osteotomy on the contralateral hip in patients with perinatal static encephalopathy.

Forty-eight patients with perinatal static encephalopathy were treated with unilateral varus rotational femoral osteotomy for hip subluxation. Twenty-one of the 48 also had concomitant pelvic osteotomy. Twenty-seven of the patients were nonambulators. Bilateral soft-tissue releases had been performed previously in 20 patients. At the time of varus rotational osteotomy, the mean age was 8 years, 11 months. The indication for a varus rotational osteotomy was femoral head subluxation or dislocation in all cases. The preoperative center-edge angle ranged from -8 degrees to 18 degrees (mean, 4 degrees), and on the contralateral side, the center-edge angle ranged from 0 degree to 32 degrees (mean, 19 degrees). The center-edge angle on the operative side at follow-up averaged 25 degrees (-10 degrees to 78 degrees), an improvement of 21 degrees, and on the contralateral side averaged 27 degrees (range, 9 degrees-40 degrees), an improvement of 8 degrees. Forty-seven patients have had no subsequent surgery on the contralateral hip. One patient had a varus rotational osteotomy on the contralateral hip 5 years postoperatively; however, this hip was subluxated at the time of the index procedure. Twelve patients have had no surgery at any time on the contralateral side. None of these patients had deterioration of the contralateral hip. Surgery on one hip should not, in itself, be an indication for surgery on the contralateral concentrically reduced hip with adequate abduction in patients with acetabular dysplasia secondary to perinatal static encephalopathy.

Acquired hallux varus.

Acquired hallux varus most commonly occurs after hallux valgus surgery. Sagittal plane, coronal plane, and varus deformities are present at the metatarsophalangeal joint. Evaluation of both the metatarsophalangeal and interphalangeal joints for mobility is necessary in surgical decision making. Not all patients require surgery. The anatomy, incidence, pathogenesis, evaluation, classification, and treatment of acquired hallux varus are discussed in this review.

[Post-operative iatrogenic hallux varus. Surgical treatment. Apropos of 19 cases].

The post operative iatrogenic hallux varus associates varus, big toe's dorsal flexion and supination. The pathogeny is dominated by musculo-tendinous lack of balance created by the initial operation and excessive exostosectomy. The authors have nineteen times surgically corrected this deformation. The procedure included in all cases, a medial arthrolysis; five times associated with a screwed capito-metatarsal osseous shelf (or graft) (when there was a metatarsal's head maiming); thirteen times associated with a metatarso-phalangeal arthrodesis (in cases of impaired joint surfaces). The authors analyse, besides, without excluding them the other surgical procedures for hallux varus, and particularly tendinous transfers. The results show the necessity of a perfect etiopathogenic analysis of the deformation.

Hallux varus: a step-wise approach for correction.

Iatrogenic hallux varus can be an unfortunate complication of hallux abducto valgus surgery. The correction of hallux varus must be performed in a well planned, step-wise method. The authors present both soft tissue and osseous corrections for hallux varus, with two case reports.
