Item 2. Management's Discussion and Analysis of Financial Condition and Results
        of Operations

Description of Business

     Our revenues are generated from the sale of products in two principal
product categories--spinal implant products and orthobiologic products. Our
spinal implant products consist of titanium or stainless steel hooks, rods and
screws and related instruments required for the surgeon to assemble a construct
which restores the natural anatomy of the spine, keeping it immobilized while a
bone graft eventually fuses the vertebrae. Our orthobiologic products consist of
synthetic bone graft substitute materials and products used to derive AGFTM. AGF
is used to provide faster, more complete bone growth and enhance the performance
of our bone graft products.

     All of our operations are located in the United States, however, we sell
our products to customers both within and outside the United States. Within the
United States, we distribute our products primarily through independent agents.
These independent agents provide a delivery and consultative service to our
surgeon and hospital customers and receive commissions based on sales in their
territories. The commissions are reflected in our income statement within
selling and marketing expense.

     For our spinal implant products, we invoice hospitals directly following a
surgical procedure in which our products are used. Our spinal implant products
are made available to hospitals from consignment inventories maintained by our
larger independent agents, or from loaner implant sets that we ship from our
facility. For our orthobiologic products, we generally ship directly to
hospitals from our facility, and we invoice hospitals upon shipment. We also
distribute AGF related products through a supply agreement with Edwards
Lifesciences Cardiovascular Resources.

     Outside the United States, we sell our products directly to distributors
who maintain an inventory of our products. We record revenue at the time of
shipment to the distributor at prices generally ranging from 40% to 70% of our
U.S. list prices. The distributors provide service to the surgeons and
hospitals, deliver products and invoice hospitals directly at prices determined
by the distributors.

     Because our revenues from U.S. hospitals are primarily at list price, and
our revenues from international distributors are at a discount to U.S. list
prices, our gross margins are subject to fluctuation based on the mix of
domestic and international sales, with domestic gross margins being somewhat
higher than international gross margins. Additionally, the spinal implant and
orthobiologic sales mix also affects our gross margins, with higher margins for
our orthobiologic products.

</TABLE>

         Sales of spinal implant products increased in the quarter ended
September 30, 2000 by $386,000 or 7.6% to $5.4 million, compared to $5.1 million
for the quarter ended September 30, 1999. The increase is attributable to higher
usage of the SynergyTM Spinal System as well as a sales price increase which
took place in October 1999.

         Sales of orthobiologic products increased by $678,000 or 15.1% to $5.2
million for the three months ended September 30, 2000, compared to $4.5 million
for the three months ended September 30, 1999. Our AGF related products, which
were launched on a nationwide basis during the second quarter of 1999, increased
by $864,000 or 113.8% and sales of synthetic bone products decreased by $186,000
or 5.0% versus the same quarter of 1999. We believe the decline in sales of
synthetic bone products is primarily related to the shift in domestic
distribution from direct sales representatives to independent agents, which we
believe are focusing a greater portion of their efforts on spinal implant
product sales. Therefore, we believe this trend is likely to continue for the
foreseeable future.

         Total domestic sales of spinal implant products and orthobiologic
products increased 14.0% or $1.1 million to $9.0 million for the three months
ended September 30, 2000, compared to $7.9 million for the same period of 1999.
International sales for the third quarter of 2000 were approximately $1.6
million and for the third quarter of 1999 were approximately $1.7 million.

                                       10
<PAGE>

         For the quarter ended September 30, 2000, the gross margin was 70.6% of
sales compared to 72.2% of sales for the quarter ended September 30, 1999. A
decrease in manufacturing overhead absorption resulting from our inventory
reduction efforts is the primary cause of the decrease in gross margin.

         Total operating expenses for the quarter ended September 30, 2000
increased by 6.9% or $388,000 to $6.0 million, compared to $5.6 million for the
same quarter of 1999, but decreased as a percentage of sales from 59.2% in the
third quarter of 1999 to 56.9% in the third quarter of 2000. Research and
development expenses increased by 29.3% or $305,000 due primarily to the hiring
of personnel and other costs related to spinal implant product development
projects and amortization of intangible assets primarily related to the AGF
technology. Selling and marketing expenses increased $230,000 or 6.6% compared
to the third quarter of 1999 primarily due to increased commissions on higher
domestic sales. General and administrative expenses decreased by 13.4% or
$147,000 due primarily to lower products liability insurance premium rates and a
lesser accrual for a profit-based bonus program.

         Net interest and other income increased $156,000 or 107.6% related
principally to an increase in interest income combined with reduced interest
expense. Interest income for the quarter ended September 30, 2000 increased
$71,000 or 59.2% compared to the third quarter of 1999 due to increased average
cash and short-term investment balances combined with higher interest rates.
Interest expense decreased during the quarter ended September 30, 2000 as a
result of the extinguishment of the convertible subordinated debentures.

         During the third quarter of 1999, we had no income tax provision due to
the utilization of net operating loss carryforwards. The valuation allowance was
reduced during the same three month period since management believes that the
deferred tax assets are more probable than not to be realized. During the fourth
quarter of 1999, the valuation allowance was eliminated. In the third quarter of
2000 we recorded an income tax provision of $580,000, which reflected an
effective tax rate of approximately 33% for the quarter and which adjusted the
year-to-date effective tax rate to 37%.

Nine months ended September 30, 1999 and 2000
---------------------------------------------

         For the nine months ended September 30, 2000, sales of $33.4 million
were $5.2 million or 18.5% higher than net sales of $28.2 million for the same
period of 1999. The following table presents sales by category (in thousands):

         Sales of spinal implant products increased in the nine months ended
September 30, 2000 by $2.9 million or 19.0% to $18.1 million, compared to $15.2
million for the nine months ended September 30, 1999. The increase reflects
continued sales growth of the SynergyTM Spinal System, aided by improved
distribution and territory coverage.

         Sales of orthobiologic products increased by $2.3 million or 17.9% to
$15.3 million for the nine months ended September 30, 2000, compared to $13.0
million for the nine months ended September 30, 1999. Sales of AGF related
products, which were launched on a nationwide basis during the second quarter of
1999, increased by $2.9 million for the nine months ended September 30, 2000
compared to the same period of 1999. Sales of synthetic bone products decreased
by $602,000 or 5.3% versus the same period of 1999. We believe the decline in
sales of synthetic bone products is primarily related to the shift in domestic
distribution from direct sales representatives to independent agents, which we
believe are focusing a greater portion of their efforts on spinal implant
product sales. Therefore, we believe this trend is likely to continue for the
foreseeable future.

         Total domestic sales of spinal implant products and orthobiologic
products increased 21.2% or $4.7 million to $26.7 million for the nine months
ended September 30, 2000, compared to $22.0 million for the same period of 1999.
International sales increased $531,000 or 8.6% to $6.7 million for the first
nine months of 2000 from $6.1 million for the first nine months of 1999.

         For the nine months ended September 30, 2000, the gross margin was
69.7% of sales compared to 70.2% of sales for the nine months ended September
30, 1999. The slight decrease reflects lower overhead absorption resulting from
our inventory reduction efforts.

         Total operating expenses for the nine months ended September 30, 2000
increased by 12.7% or $2.1 million to $18.7 million, compared to $16.6 million
for the same period of 1999, and as a percentage of sales decreased from 58.8%
in the first nine months of 1999 to 55.9% in the first nine months of 2000.
Research and development expenses increased by 24.1% or $742,000 due primarily
to the hiring of personnel and other costs related to spinal implant product
development projects and amortization of intangible assets related to the AGF
technology . Selling and marketing expenses increased $1.3 million or 12.5%
compared to the first nine months of 1999 primarily due to increased commissions
on higher domestic sales. General and administrative expenses decreased $187,000
or 5.8% due primarily to lower products liability insurance premium rates.
During the second quarter of 2000, a non-recurring charge of $268,000 was
recorded in connection with the withdrawal of a proposed secondary public stock
offering.

         Net interest and other income increased $300,000 or 86.2% related
principally to an increase in interest income combined with reduced interest
expense. Interest income for the nine months ended September 30, 2000 increased
$169,000 or 53.8% from the same period of 1999 due to increased average cash and
short-term investment balances combined with higher interest rates. Interest
expense decreased during the nine months ended September 30, 2000 as a result of
the extinguishment of the convertible subordinated debentures.

         During the first nine months of 1999, we had no income tax provision
due to the utilization of net operating loss carryforwards. The valuation
allowance was reduced during the same nine month period since management
believes that the deferred tax assets are more probable than not to be realized.
During the fourth quarter of 1999, the valuation allowance was eliminated. In
the first nine months of 2000 we recorded an income tax provision of $1.9
million, reflecting an effective tax rate of approximately 37%.

Liquidity and Capital Resources

         In the first nine months of 2000, our operating activities generated
$4.7 million of net cash. We invest our excess cash in U.S. Treasury securities
and high-grade marketable securities. At September 30, 2000, cash, cash
equivalents and short-term investments totaled $14.9 million as compared to $9.8
million at December 31, 1999. We also have a $5.0 million revolving line of
credit available to us that had no amount outstanding at September 30, 2000 and
which expires in June 2001.

         We have used and may continue to use our cash, our common stock, or a
combination of both to pay for purchased technologies, product lines, mergers
and acquisitions. We also intend to continue to invest in the development of our
business. We believe we currently possess sufficient resources to meet the cash
requirements of our operations for at least the next year. However, some of the
aforementioned activities may require cash in excess of that which we currently
possess, and we can give no assurance that we will be able to raise the
additional capital on satisfactory terms, if at all.

         At September 30, 2000, we had no material commitments for capital
expenditures.
