Experimental Study on Rats with Critical-Size Bone Defects Comparing Effects of Autologous Bone Graft, Equine Bone Substitute Bio-Gen Alone or in Association with Platelet-Rich Fibrin (PRF).

Background: A critical-sized bone defect (CsBD) is considered one that will not heal spontaneously and requires reconstruction. This study aims to compare the results of using different bone reconstructive techniques and to study the potential of platelet-rich fibrin (PRF) to enhance the healing properties of a bone substitute (BS).

Methods: In this experimental study on rats, the treatment of critical-sized bone defects was carried out by analysing four groups: a control group in which the bone defect was left empty; a group treated with Bio-Gen; another group in which the defect was treated with PRF in combination with Bio-Gen; and the last that was treated with autologous bone graft (ABG).

Utility of "reposition-flap" in the reconstruction of the avulsed thumb.

Injuries that result in thumb amputation cause a loss of 50% of hand function. Microsurgical replantation remains the gold standard of thumb reconstruction techniques. The non-microsurgical technical variants of thumb reconstruction described so far aim to create a neo-thumb of adequate length, stable, opposable, sensitive, and last but not least esthetically pleasing appearance.

Arterial only anastomosis associated with modified Baudet technique in ear replantation: Case reports and literature review.

Background: Total ear amputation is a relatively rare trauma with an absolute indication for surgical treatment. Numerous techniques for auricular reconstruction have been described. When local and general conditions allow microsurgical replantation, this must be the first choice.

Idiopathic tenosynovitis with rice bodies.

Purpose: Idiopathic tenosynovitis with rice bodies is a rare disease and its non-association with rheumatic diseases, tuberculosis infection or trauma is reported only in few cases in literature.

Patients, Materials And Methods: Our study presents a series of five patients diagnosed with tenosynovitis with rice bodies at the flexor tendons of the upper limb. Medical history revealed no associated disease or trauma.
