Introduction

Conservative treatment of Achilles tendon ruptures may lead to re-rupture. Open surgical repair entails a risk of skin necrosis or infection. Several percutaneous techniques have been used, like Tenolig® or Achillon®, but these techniques are costly and may be marred by wound healing problems. Ma and Griffith described a technique for percutaneous repair witch left the suture and the knot under the skin, thus reducing the risk for infection.

Material and Methods

From January 2001 to September 2006, we used this percutaneous treatment for 60 acute ruptures of Achille tendon. The repair was made under local anaesthesia, using a single or double absorbable suture. Postoperative care was 3 weeks immobilisation in a cast in equinus position with no weight bearing, followed by another 3 weeks in a cast with the ankle at 90° with progressive weight bearing.

Purpose: During the second half of the 80s, Grammont, Trouilloud and Guichet developed a centromedullary nail for progressive limb lengthening. We analysed retrospectively twenty lengthenings, studying the clinical and radiological results to examine the quality of callus formation.

Material and methods: This study included eighteen patients, thirteen men and five women, who underwent lengthening procedures between 1991 and 2000. The patient’s clinical files were analysed in addition to the results of a physical examination. A standardised x-ray protocol was used to analyse bone regeneration.

Results: Mean follow-up was 4.55 years (1.5–10.5). Mean lengthening was 46 mm (30–80) achieved at a mean rate of 1.28 mm/d. The Bastiani index was 26 j/cm. Complications were: one progressive external popliteal sciatic palsy, one persistent knee flexion, one premature callus consolidation, and two callus fractures after nail removal. All patients maintained their activity level. The quality of regenerated bone was better in the dorsal and medial segments exposed to more stress. The callus was cortical and remodelled after removal of the nail.

Discussion: Like all lengthening techniques, the Albizzia nail requires careful preoperative planning, particularly to determine the level of the endomedullary osteotomy. The clinical results in this series were globally satisfactory. The callus was similar to cortical bone and quite different from the callus obtained with external lengthening methods, but our study demonstrated the excellent quality of the regenerated bone. The Albizzia nail can also be left in place until a solid reliable callus has formed, an advantage compared with external fixation which is less well tolerated.

Purpose: Patellar instability raises serious clinical and therapeutic problems in children. We present our results with the “soft baguette” technique used since 1974.

Material and methods: Sixty-four patients (50 girls and 14 boys) (85 knees) treated between 1974 and 2000 were reviewed. Mean follow-up was 140 months (14–234). For eight knees, section of the lateral wing of the patella was associated. The five types of patellar instability, from permanent dislocation to potential instability, were represented.

Results: At last follow-up, 84% of our patients were satisfied with significant improvement in pain, instability and patellar track. We had minor complications in 23.5% of the knees (haematoma, effusions) and eleven recurrences (9.5%) at mid- or long-term which were considered failures. There were no cases of epiphysiodesis. A neoTTA developed in eight cases, proving the efficacy of realignment of the medialised patellar ligament. Following changes in the mechanical axis of these knees revealed a clear trend towards increased valgus.

Discussion: The soft baguette technique has fulfilled expectations: stabilisation of the extensor system without injuring the growth cartilage, and trochlear remodelling for the younger patients. The trend towards increased valgus raises a problem. Because of this risk, if the initial valgum is greater than 5° we emphasise the theoretical importance of temporary medial epiphysiodesis associated with the soft baguette to control this potential source of recurrence and therapeutic failure.

Purpose: We performed a biometric evaluation of the femoral trochlea in the human foetus and compared measurements with those observed in the adult in order to search for correlations with other biometric parameters of the human femur.

Material: Twenty-two foetuses with no orthopaedic anomalies were preserved in formol. The 44 knees were studied. Fœtal age varied from 26 to 40 weeks.

Method: After anatomic dissection, digital photographic documents were analysed using angular measurement software. The following dimensions were measured on the distal epiphysis: anteroposterior thickness of the condyles, protrusions of the lateral and medial trochleal edges, the difference in condyle height, the trochlear opening angle alpha, trochlear slope. Femoral anteversion, length of the femoral neck, and the neck-shaft angle were measured on the AP view of the femur.

Spearman’s test was used to search for correlations. Results were compared with those measured under the same conditions in a series of 32 adult knees published by Wanner.

Results: The alpha angle of trochlear opening was 148° with a coefficient of variability of 4%. The alpha angle was greater than 150° in 18 trochleae. The lateral edge of the trochlea was higher than the medial edge in 37/44 trochleae. There was no correlation by age and sex.

The femoral measurements showed 27.01° anteversion with very wide variability (coefficient 46%) and no correlation with trochlear opening.

No significant differences were observed between the fœtal and adult measurements.

Discussion: Our data are the first reporting anatomic measurements of the fœtal trochlea. The morphology of the lower extremity of the femur during the third trimester of pregnancy is globally the same as in adult femurs. Morphological changes of the proximal femur occurring during growth do not appear to modify the morphology of the distal femur. The deep and asymmetrical engagement of the patella onto the trochlea is a characteristic of modern man and is considered to be a consequence of bipedal stance. Our study would appear to confirm that the anatomic characteristics of the human trochlea have been integrated into the genome in the course of evolution. This suggests that a genetic origin of trochlea dysplasia, as suggested by Dejour, is a reasonable hypothesis.
