We assessed peripheral nerve function during and after lower-limb lengthening by callotasis in 14 patients with short stature, using motor conduction studies. Four patients with short stature of varying aetiology showed unilateral and one showed bilateral weakness of foot dorsiflexion. Both clinical and electrophysiological abnormalities consistent with involvement of the peroneal nerve were ob...
Small cell osteosarcoma (SCO) is the most rare subtype of osteosarcoma and has a poor prognosis. An 11-year-old boy presented with 2-month history of painful tumefaction in the lower leg. Imaging analysis demonstrated a mixture of osteolytic and osteosclerotic lesions in the proximal tibia and extraskeletal area. Histology of the open biopsy showed small round cells producing mucous matrix. Bas...
This paper describes a new technique for greater trochanteric hip arthroplasty in which the femur is divided at the subtrochanteric level and the upper fragment rotated through 180 degrees to place the greater trochanter deeply in the acetabulum; with the lower limb in the weight-bearing position the fragments are then fixed with a short intramedullary nail. This operation was carried out in a ...
A modular endoprosthetic system has been developed at the Groningen University Hospital and the University of Twente. The system can bridge a defect resulting from the resection of a malignant bone tumour which has developed around the knee joint of a child. Since the other healthy leg continues to grow, the system includes an element whose length can be adjusted non-invasively by using an exte...
When people make decisions, do they give equal weight to evidence arriving at different times? A recent study (Kiani et al., 2008) using brief motion pulses (superimposed on a random moving dot display) reported a primacy effect: pulses presented early in a motion observation period had a stronger impact than pulses presented later. This observation was interpreted as supporting the bounded dif...
There are many techniques for limb lengthening. Lengthening over a plate is an alternative choice of fixation in children or when nailing is difficult. We present a new technique for tibial lengthening with using a monolateral external fixator over a lengthening plate.Lengthening over an intramedullary nail is a commonly used method in patients with short stature or limb-length discrepancy. How...
Traction injury to the sciatic nerve can occur during hamstring lengthening. The aim of this study was to monitor the influence of hamstring lengthening on conduction in the sciatic nerve using evoked electromyography (EMG). Ten children with spastic cerebral palsy underwent bilateral distal hamstring lengthening. Before lengthening, the evoked potential was recorded with the patient prone. Dur...
Background and purpose - Femoral lengthening may result in decrease in knee range of motion (ROM) and quadriceps and hamstring muscle weakness. We evaluated preoperative and postoperative knee ROM, hamstring muscle strength, and quadriceps muscle strength in a diverse group of patients undergoing femoral lengthening. We hypothesized that lengthening would not result in a significant change in k...
Limb lengthening by Ilizarov lengthens not just the long bone, but also the soft tissues too. Damage of the musclesduring corticotomy and their stretching during distraction play a crucial role in occurrence of complications and finallimb function. We present here a systematic codified nomenclature system of each muscle summarising all theinfluence that corticotomy and distraction have the part...
Comparison of silk sutures and 2–ethyl–cyanoacrylate on wound closure following surgical crown lengthening using apically positioned flap surgery Dr. A. Moghareh Abed* - Dr. M. E'tesampoor*** Assistant Professor of Periodontics Dept., Faculty of Dentistry, Isfahan University of Medical Sciences. ** Dentist. Background and Aim: The use of cyanoacrylate tissue glue as an alternative to silk sutur...
