Percutaneous Retrograde Intramedullary Pin Fixation for Isolated Metacarpal Shaft Fracture of the Little Finger: Soo Hong Han, Hyung Ku Yoon, Dong Eun Shin, Seung Chul Han, Young Woong Kim; J Korean Fract Soc 2010;23(4):367-372.

PURPOSE
To evaluate the anatomic and functional outcome of retrograde intramedullary single wire fixation for metacarpal shaft fractures of the little finger.
MATERIALS AND METHODS
hirty one consecutive patients with closed metacarpal shaft fractures of the little finger who have been treated with retrograde intramedullary single wire fixation were evaluated. Fracture union and angulation were analyzed radiologically, and clinical evaluations were performed including range of motion, DASH score and complications.
RESULTS
Fracture union was achieved in all cases and callus formation was obvious at postoperative 41 days. Average angulation of fracture site was 3degrees in the coronal plane and 1.2degrees in the sagittal plane at the last follow up and no measurable metacarpal shortening was observed. Mean TAM was 253degrees and DASH score was 2.6. There were two cases of pin migration as intermediate complications.
CONCLUSION
Closed reduction with subsequent percutaneous retrograde K-wire fixation produced good radiological and functional results. We recommend this minimally invasive technique which provides adequate fixation of displaced little finger metacarpal shaft fractures with good functional results and low morbidity.

Operative Treatment of Metacarpal Shaft Fracture>: Comparision of Low-Profile Miniplating System and Kirschner Wire Fixation: Hyun Dae Shin, Kwang Jin Rhee, Kyung Cheon Kim, Ho Sup Song; J Korean Fract Soc 2005;18(2):105-109.

Abstract PDF: PURPOSE
To compare Kirschner wire fixation and low profile miniplating system in metacarpal shaft fracture.
MATERIALS AND METHODS
Patients, available at least 1 year, who received the operative treatment after being diagnosed as metacarpal shaft fracture from 1997 May to 2003 May were the subjects with the exclusion of thumb fracture and intraarticular metacarpal bone fracture and also cases involving Kirschner wire fixation on severe laceration or open fracture. On the last follow up total action motion (TAM) and plain radiographes was checked.
RESULTS
In 7 cases (38.9%) where closed reduction and Kirschner wire fixation were carried out, 8 cases (61.5%) where open reduction and Kirschner wire fixation were carried out and 24 cases (88.9%) where open reduction using miniplate and screw showed either excellent or good results on TAM. 5 cases of dorsal angulation occured in closed reduction and Kirschner wire fixation group and 4 cases of dorsal angulation in open reduction and Kirschner wire fixation group however no cases of dorsal angulation occured in open reduction and miniplate and screw fixation group, and in all cases no rotational deformity, complications through ulnar or radial angulation occured. Internal fixation was carried out on 2 cases of nonunion which had closed reduction and Kirschner wire fixation carried out, while the rest all showed bony union.
CONCLUSION
Selective use of low profile miniplate and screw fixation in the metacarpal shaft fracture is more effective than in cases of comminuted fracture which can not be achieved firm fixation by Kirschner wire fixation. Low profile miniplate and screw fixation can get more precise anatomical reduction and firm fixation so it allow early return to daily living activity and show low complication rate.

Metacarpal Shaft Fracture Treated by Closed Reduction and Percutaneous Intramedullary K-wire Fixationv: Soo Joong Choi, Chang Kyun Lim, Ho Guen Chang, Jun Dong Chang, Chang Ju Lee; J Korean Soc Fract 1998;11(1):100-106. Published online January 31, 1998; DOI: https://doi.org/10.12671/jksf.1998.11.1.100

Abstract PDF: The metacarpal shaft fracture has been reported as a stable fracture relatively, but operative treatment is indicated when there happens reduction loss, or is in need of early exercise. Intramedullary K-wire fixation has been used for unstable transverse or long oblique diaphyseal fracture of the metacarpal bone. The fracture site is not opened and the K-wires are introduced under X-ray control. The techniques can stablize the fracture site and allow immediate exercise postoperatively. We experienced 9 cases of 4th metacarpal shaft fracture treated by percutaneous intramedullary K-wire frxation with modified technique. The K-wire was used one or two ezch metacarpal fracture. The types of fracture were 4cases of transverse, 3 of oblique, 2 of comminuted. The average clinical union period were 5 weeks. There were not severe complications in all cases.
