Abstract:
Introduction. Fractures of the Mt (Mt) bones prezent a range of 19% - 35% of the
osteoarticular system trauma. 88 % fracture of Mt fractures are the rays 2-3-4-5, and the fifth
Mt bone have up to 10% of hand bone fractures.
Aim of the study. To evaluate the intermediate term results (follow up of two years) of distal
humerus fractures according to data from medical records, classification, type of implant used
in fracture fixation, specific parameters of elbow postsurgical treatment.
Materials and methods. We have proposed a study of patients with fractures of the Mt bones
which consecutively was treated in departament of Hand Surgery with the application of
microsurgical techniques, of Traumatology and Orthopedics Clinical Hospital, Chisinau in the
period 2018-2019. Final outcomes was determined by using Disabilities of Arm and Shoulder
and Hand (DASH) score and the wrist MAYO score calculated along with complete range of
motion. All results were presented as mean ± standard deviation (±SD).
Results. First Mt fracture was in – 10 cases (5 cases - shaft fracture; Rolando/Bennett fractures
-5 cases), fracture of 2 or more rays 10 cases, and rest cases were one ray Mt bone fracture -
115 cases, where 75(55,5%) patients has been with subcapital fractures of fifth Mt bone, and
in total were investigate 135 patients. The average age is 30,05 years (max 67, min 15 SD
±10,45) The report between sex was 8,4:1 (121:14) with predominance of male gender. In fresh
and less comminuted fractures cases was achieved close reduction of Mt and fixation was
obtained with k-wires in 56 (41,8%) cases.. In rest patients were apply open reduction and
internal fixation with the k-wires by segment fracture of Mt subcapital fracture - 43(31,85%)
patients, shaft segment 30 (22,22%) patients, and 10 (7,41%) with fracture of the base of Mt.
All fractures healed, and radiographic union was observed at an average of 1,5-3 months. Was
possible to investigate MAYO and DASH scores at 19 patients with a mean of 88±19 and
19±20.
Conclusions. Outcome of open reduction and internal fixation of fractures of the Mt bones
usually can result in high union rates, and a good result can be obtained with perfect reduction
of the Mt fragments fracture and it is desired as soon is possible for an acceptable outcome
DASH and MAYO scores.
