The aim of this study was to evaluate the changes of biochemical markers during fracture healing in patients with osteoporosis. The study included 26 patients; 9 underwent hip hemiarthroplasty (mean age +/- SD: 71.0 +/- 10.2 years, group EN) for femoral neck fractures. 7 underwent osteosynthesis (75.3 +/- 8.2 years, group OS) for trochanteric fractures, and 10 subjects had spinal compression fractures (68.2 +/- 12.0 years, group CO). No operative procedures were performed in group CO. ⋯ No biochemical markers changed significantly in group CO. In conclusion, bone resorption was accelerated at an early stage due to acute osteonecrosis or bed rest, followed by bone formation due to callus or mechanical stress later on. As far as bone resorption markers are concerned, 24 weeks are enough to eliminate the effect of fracture.

Review Case ReportsBilateral calcaneal fracture in childhood. Case report and review of the literature.
Calcaneal fractures in young children are rare. Bilateral calcaneal fractures in this age group are exceptional. In the literature only 4 cases of bilateral calcaneal fractures have been reported, and the youngest patient was 6 years old (range 6-17 years). ⋯ This is confirmed by other studies. It is not unlikely that the incidence is indeed higher because the joint involvement in childhood injuries is often subtle, and the fracture can easily be overlooked on initial X-ray examination. We survey the literature and report the case of a 5-year-old boy who sustained bilateral calcaneal fractures and an additional fracture of the neck of the talus on one side, a combination which to our knowledge has never been described before.

Review Case ReportsRecurrent dislocation of tibialis posterior tendon. A report of two cases.
We successfully treated two patients with recurrent dislocation of the tibialis posterior tendon by creating a bone block. Sudden resistive contraction of the tibialis posterior muscle is considered to be the mechanical cause of the initial traumatic injury, and a shallow tibialis posterior tendon sulcus may be the predisposing factor. ⋯ When treating patients with a complaint of long-standing pain around the medial malleolus, we must bear in mind the possible diagnosis of recurrent dislocation of the tibialis posterior tendon. If the patient can voluntarily dislocate the tendon by active plantar flexion and inversion of the ankle, the diagnosis is definitive.

Case ReportsBilateral pathological femoral neck fractures secondary to ectopic parathyroid adenoma.
A rare case of bilateral pathological femoral neck fractures secondary to ectopic parathyroid adenoma is reported. Both hip fractures were treated with closed reduction and internal fixation. The right hip fracture healed uneventfully, whereas the left hip fracture developed non-union that required subtrochanteric osteotomy and internal fixation and eventually healed. Neither hip developed avascular necrosis.

Supracondylar process syndrome of the humerus has received little attention in the orthopaedic literature. This case report presents a patient with this condition.
