Introduction and Purpose. Metacarpal fractures constitute approximately one third of all hand fractures. The majority of these fractures are treated by conservative non-surgical methods. The aim of this study is to obtain the appropriate anatomical alignment of the fracture with dynamic metacarpal stabilization splint (DMSS) and to maintain the proper bone anatomy until the union is achieved. In addition, by comparing this method with short arm plaster splint (SAPS) application, it is aimed to evaluate whether patients are superior in terms of comfort, range of motion (ROM) and grip strength. Materials and Methods. In our study, SAPS or DMSS was applied to the patients with 5th metacarpal neck fracture randomly after fracture reduction and followed for 3 months. A total of 119 patients with appropriate criteria were included in the study. Radiological alignment of the fracture and amount of joint movements were evaluated during follow-up. Grip strength was evaluated with Jamar dynamometer. EQ-5D-5L and VAS scores were used for clinical evaluation. Results. 103 patients completed their follow-up. 51 patients were treated with SAPS and 52 patients were treated with DMSS. The mean age of the SAPS was 29.5 (SD ± 9.4; 16–53 years) and the mean age of the DMSS group was 27.8 (SD ± 11.6; 16–63). Pressure sores was seen in 5 patients in the DMSS group, while no pressure sore was seen in the SAPS (p = 0.008). There was no significant difference between the two groups in the VAS scores at all times. There was no significant difference between the mean dorsal cortical angulation (DCA) before the reduction, after the reduction and at the third month follow-ups. There was no statistically significant difference between the length of metacarps at first admittion before reduction, after reduction and at third month follow-ups. When the grip strength of the two groups were compared as a percentage, the grip strength of the patients in the DMSS group was found to be higher at 1st month, 2nd month and 3rd month (p <0.001). When the ROM values of the patients were evaluated, DMSS group had a higher degree of ROM in the first month compared to the SAPS group (p <0.001). No statistically significant difference was detected among groups at third month in the ROM of the IP and MP joints. However, wrist ROM was statistically higher in DMSS group at 3rd month (p <0.05). There was a statistically significant difference between EuroQol scores in favor of DMSA group (p <0.05). Discussion and Conclusion. In stable 5th metacarpal neck fractures, DMSA is as effective as SAPS to maintain bone anatomy. In addition, DMSA can be preferred for fixation plaster splint or circular plaster applications for the prevention of reduction in boxer fractures, with the advantage of having high clinical scores, which is an indication of early acquisition of grip strength, ease of use and patient comfort

Background: The occurrence of congenitally short metatarsals is associated with an abnormal gait and an aesthetically displeasing appearance. Similarly, short metacarpals result in severe cosmetic disfigurement, particularly in young female patients.

Methods: We examined and performed bone lengthening surgery in 13 female and 2 male patients. Of these, procedures were conducted on 12 metatarsals of 8 patients, 4 metacarpals and 1 metatarsal of a single patient, 1 metacarpal and 1 metatarsal of a single patient and 7 metacarpals of 5 patients. The mean age of the patients who underwent metacarpal procedures was 14.5 (10–21) years while the mean age of those who underwent metatarsal procedures was 17.5 (10–25) years. The callotasis method was employed for these procedures and we used either a unilateral external fixator and/or a circular external fixator.

Results: The mean healing index and increase in metacarpal length was 1.6 (1.1–2.3) months/cm and 17.6 (13–26) mm, respectively. The mean follow-up period for patients who underwent metacarpal lengthening was 57.5 (12–96) months. The mean healing index and increase in metatarsal length was 1.6 (1.0–2.0) months/cm and 24.3 (20–30) mm respectively. The mean follow-up period for patients who underwent metatarsal lengthening was 48.3 (12–72) months. The preoperative AOFAS (American Orthopaedic Foot and Ankle Society) scores were good in 5 and excellent in 9 cases. The functional scores of metatarso-phalangial (MTP) joint of lengthened metatarsals for the lesser toe were excellent in 12 and good in 2 cases based on the AOFAS scoring system. All patients who underwent metacarpal lengthening reported that they were satisfied and could conduct their daily activities with good functional and aesthetic results. Complications included 4 angulations, 1 subluxation and 1 non-union and were seen in 6 of the metatarsal lengthening cases that exceeded 40% (or > 20 mm) of the total length of the original bone.

Interpretation: There are recommendations in the literature that allow for the avoidance of severe complications and for the shortening of the consolidation period. We conclude that the periosteum must be protected with percutaneus osteotomy and lengthening should be performed at a rate of 0.25 mm twice a day, should not exceeding 40% of the original bone length (or > 20 mm). If the anticipated lengthening exceeds these predefined values then we suggest that the procedure should be performed using a circular external fixator with temporary fixation of the MCP or the MTP joint and the inclusion of the proximal phalanx in the frame.
