ABSTRACT

NEW PATHOPHYSIOLOGICAL INSIGHTS: Based on improved knowledge of the vascular supply of the proximal femur, a safe surgical dislocation of the hip joint was established allowing direct insights to the pathomorphological malfunctioning of the joint. One insight was that slipped capital femoral epiphysis (SCFE) impingement leads to substantial damage of the chondrolabral rim area, even in the presence of minor slips. A further surgical development was the extended retinacular flap allowing for correction of the deformity with calculable risk for iatrogenic necrosis. CONSECUTIVE SURGICAL CONCEPT: In 20 years of experience, a treatment concept for SCFE could be established which replaces classic pinning in situ and indirect correction of the deformity with subcapital re-alignment when the physis is still open, with true femoral neck osteotomy for hips with closed physis. Pinning in situ still has a place in minor slips but should be combined with open or arthroscopic recreation of an anterior metaphyseal waisting. UNEXPECTED COMPLICATION: Loss of joint stability is a rare complication of anatomic re-alignment. It can be disease-related when the impingement has induced severe destruction of acetabular cartilage. It can be related to the surgical procedure, especially when the neck was excessively shortened and refixation of the trochanter was not advanced. Finally, in cases with severe and long-lasting deformity, the acetabulum may undergo adaptive flattening, being the cause of joint destabilisation with the correction of the deformity. Advancement of the greater trochanter and/or peri-acetabular osteotomy may be discussed to restabilise the joint.

ABSTRACT

UNLABELLED: The knee has various pathologic appearances in patients with congenital longitudinal deformities of the lower extremities. Radiographs from 39 patients with unilateral longitudinal congenital deficiencies of the lower extremities were analyzed to describe epiphyseal and metaphyseal configurations and position of the epiphyseal plate. We defined 22 radiographic parameters of the femur and tibia, calculated the mean values, and compared the parameters of the affected knee with the unaffected knee for patients in different age groups. In the femur, we observed hypoplasia of the lateral condyle in width and height. In the tibia, the lateral condylar hypoplasia was manifest primarily by lateral horizontal deficiency. Age group comparisons showed no horizontal epiphyseal deficiencies in the older patients, but there was persistence of vertical epiphyseal deficiencies. Bony deformities in congenital longitudinal deficiencies mainly were attributable to dysplasia of the lateral epiphysis in the distal femur and proximal tibia, whereas positions of the epiphyseal plate had varying physiologic values. LEVEL OF EVIDENCE: Diagnostic study, Level II. See the Guidelines for Authors for a complete description of levels of evidence.

ABSTRACT

AIM: The Ponseti method for the treatment of congenital clubfeet has been propagated due to the sometimes disappointing functional results after surgical treatment. The aim of our study was to evaluate our early results and experiences with the Ponseti method. METHOD: Between December 2002 and December 2004 a total of 87 clubfeet in 59 patients were treated using the Ponseti method at our department. Only patients in whom treatment was initiated within the first three weeks of life were included in this study. Rate of successful correction without open release surgery, radiological findings, classification according to Pirani at the time of the last follow up, recurrence rate and duration of treatment were defined as outcome measures for this prospective study. RESULTS: Fifty-nine cases in 37 patients met the inclusion criteria. Ninety-three percent of all cases (55 feet) were corrected without open surgery. The mean duration of active treatment was 11.4 weeks (8-20 weeks). The mean tibiocalcaneal angle 3-4 weeks after the percutaneous tenotomy of the Achilles tendon was 69 degrees, the mean a.-p.-talocalcaneal angle measured 33 degrees and the lateral talocalcaneal angle 36 degrees. A recurrence was seen in one patient with bilateral clubfeet (3.6 %). CONCLUSION: Open release surgery can be averted in most cases of idiopathic clubfoot using the Ponseti method. Scarring of the soft tissue and especially of the joint capsule can thereby be avoided.

ABSTRACT

Congenital unilateral anterolateral tibial bowing in combination with a bifid ipsilateral great toe is a very rare deformity which resembles the anterolateral tibial bowing that occurs in association with congenital pseudarthrosis of the tibia. However, spontaneous resolution of the deformity without operative treatment and with a continuously straight fibula has been described in all previously reported cases. We report three additional cases and discuss the options for treatment. We suggest that this is a specific entity within the field of anterolateral bowing of the tibia and conclude that it has a much better prognosis than congenital pseudarthrosis of the tibia, although conservative treatment alone may not be sufficient.
