Bilateral Stress Fractures of Amputated Tibial Stumps in the Setting of Chronic Compartment Syndrome.

Introduction: Limb amputation and subsequent prosthetics lead to significant disturbances in bone residual limb remodeling.

Aim: To familiarize specialists with the possibility of simultaneous bilateral stress fractures of amputation residual limbs resulting from intensive loads and poor-quality prosthetics causing chronic compartment syndrome. A case of bilateral stress fractures of the tibia in a 28-year-old male military serviceman with paired transtibial amputation is presented.

Vascularization of a bone stump.

Aim To study the character of blood circulation in the bone stump at tight and loose closure of the medullary cavity. Methods Two series of experiments on 39 rabbits with mid-third femoral amputation and muscular plasty were carried out. In the 1st (experimental) series, the bone scapula was closed by thin cortical autograft taken from the epimetaphyseal area, and then the muscles were sutured, and in the 2nd - the scapula was closed by myoplasty only.

BIOMECHANICAL FACTORS IN RESIDUAL LIMB FORMATION AFTER AMPUTATION.

Objective: The aim: To study the influence of biomechanical factors on the character of morphological disorders in the process of reparative regeneration at the end of the residual limb after amputation.

Patients And Methods: Materials and methods: 10 series of experiments on 144 rabbits were conducted. We used myodesis with normal, insufficient and excessive muscle tension, their electrical stimulation, tight and leaky closure of the bone marrow canal.

Reamputation stumps below knee.

Aim To investigate rehabilitation outcomes of patients with malformed tibial stumps. Methods Observations included 421 patients with residual limb diseases and malformations (extensive inactive scars adhered to the bone, excessively long or short stumps, bone filing, osteomyelitis of the stump, muscle attachment to the skin scar, excessive mobility and deviations of the fibula, improper filing). Four hundred and thirty-six (436) reconstructive surgeries were performed.

REPARATIVE REGENERATION AT THE END OF BONE FILING AFTER OSTOPLASTIC AMPUTATION.

Objective: The aim: To study the role and place of bone grafting in the formation of bone stump after amputation.

Patients And Methods: Materials and methods: 3 series of experiments were carried out on 44 rabbits with amputation of the thigh in the middle third and stump grafting using osteoplastic hermetic closure of the canal with a thin cortical plate (series I), closure of the canal with a spongy bone (series II), and loose closure of the canal with a cortical graft located at the entrance to the canal at an angle of 30° (ІІІ series). Observation period: 1, 3, 6 months.

The relationship between homocysteine level and vitamins B12, B9 and B6 status in patients with chronic kidney disease.

Objective: Introduction: According to present knowledge, hyperhomocysteinemia is one of the risk factors of cardio-vascular pathology. Patients with chronic kidney disease are known to develop hyperhomocysteinemia more often than those in general population. Іmportant cause of hyperhomocysteinemia is the deficiency of vitamins В6, В9 and В12 that are involved in homocysteine metabolism.
