SCHEDULE 13D/A

This Amendment No. 10 (this Amendment) to the Schedule 13D (the Schedule 13D) is being filed on behalf of
Prescott Group Capital Management, L.L.C., an Oklahoma limited liability company (Prescott Capital), Prescott Group Aggressive Small Cap, L.P., an Oklahoma limited partnership (Prescott Small Cap), Prescott Group Aggressive
Small Cap II, L.P., an Oklahoma limited partnership (Prescott Small Cap II and, together with Prescott Small Cap, the Small Cap Funds), and Mr. Phil Frohlich, the principal of Prescott Capital, relating to Ordinary
shares, NIS 0.01 par value (the Ordinary Shares), of Modsys International Ltd., an Israeli company (the Issuer).

The Ordinary Shares held by Prescott Master Fund reported on this Schedule 13D were previously reported on a Schedule 13G/A filed with the
Securities Exchange Commission on May 11, 2010 and a Schedule 13D filed with the Securities Exchange Commission on June 2, 2010, as subsequently amended on January 6, 2011, again on June 27, 2011, again on December 16, 2011,
again on April 27, 2012, again on September 12, 2012, again on November 26, 2013, again on December 12, 2014, again on January 4, 2016 and again on January 5, 2017. Capitalized terms used herein but not defined have the
respective meanings given to them in the Schedule 13D.

Item 3 of the Schedule 13D is hereby amended as follows:

Item 3.

Source and Amount of Funds

As of April 4, 2017, the Small Cap Funds had
invested $17,291,524 (inclusive of brokerage commissions) in Ordinary Shares of the Issuer. The source of these funds was the working capital of the Small Cap Funds.

Item 4 of the Schedule 13D is hereby amended by adding the following:

Item 4.

Purpose of the Transaction

Item 6 is incorporated herein by reference.

Item 5 of the Schedule 13D is hereby amended as follows:

Item 5.

Interest in Securities of the Issuer

(a) The aggregate percentage of Ordinary
Shares reported to be owned by the Reporting Persons is based upon the sum of (i) 19,086,159 Ordinary Shares outstanding, which is the total number of Ordinary Shares outstanding as of March 8, 2017, as reported in the Issuers most
recent 10-K filed with the Securities Exchange Commission on March 10, 2017, plus (ii) 1,073,653, the number of warrants exercisable to purchase Ordinary Shares held by the Reporting Persons, plus (iii) 216,000, the number of
preferred shares convertible into Ordinary Shares held by the Reporting Persons.

As of April 4, 2017, the Small Cap Funds
beneficially owned approximately 5,685,929 Ordinary Shares, representing approximately 27.9% of the issued and outstanding Ordinary Shares of the Issuer. Such Ordinary Shares consist of (i) 4,396,276 Ordinary Shares, (ii) warrants
exercisable to purchase 1,073,653 Ordinary Shares and (iii) preferred shares convertible into 216,000 Ordinary Shares.

Prescott Capital, as the general partner of the Small Cap Funds, and Mr. Frohlich, as
managing member of Prescott Capital, may also be deemed to beneficially own the 5,685,929 Ordinary Shares held by the Small Cap Funds, representing approximately 27.9% of the issued and outstanding Ordinary Shares of the Issuer.

Prescott Capital and Mr. Frohlich disclaim beneficial ownership of the Ordinary Shares held by the Small Cap Funds except to the extent
of their pecuniary interest therein.

(b) By virtue of his position with Prescott Capital and the Small Cap Funds, Mr. Frohlich has
the sole power to vote and dispose of the Ordinary Shares owned by the Small Cap Funds reported in this Schedule 13D.

The filing of this
Schedule 13D shall not be construed as admission that Prescott Capital or Mr. Frohlich is for the purposes of Section 13(d) or 13(g) of the Act the beneficial owner of any of the 5,685,929 Ordinary Shares owned by the Small Cap Funds.
Pursuant to Rule 13d-4, Prescott Capital and Mr. Frohlich disclaim all such beneficial ownership.

(c) Other than the acquisitions
described in Item 6 hereof and the receipt by the Reporting Persons of 16,000 preferred shares convertible into 16,000 Ordinary Shares as a dividend for 2016 on the preferred shares held by the Reporting Persons, there were no transactions in
the Issuers securities during the sixty days prior to the date hereof made by the Reporting Persons.

(d) No person other than the
Reporting Persons is known to have the right to receive, or the power to direct the receipt of dividends from, or proceeds from the sale of, the Ordinary Shares.

(e) Not applicable.

Item 6
of the Schedule 13D is hereby amended as follows:

Item 6.
